Description

Technical Field

[0001] This invention relates to the field of honing equipment technology, specifically to a support device and honing equipment. Background Technology

[0002] Deep hole honing equipment is a special machine tool used for precision machining of cylindrical deep holes. It includes a drive unit, a honing rod, and a honing head. The drive unit drives the honing rod to drive the honing head to perform a combination of rotation and reciprocating motion inside the hole, so as to achieve high-precision finishing of the inner hole of the workpiece.

[0003] However, due to the large length-to-diameter ratio of deep-hole workpieces, the required overhang length of the honing rod is relatively long, resulting in lower rigidity of the honing rod. In actual machining, the honing rod exhibits significant deflection during high-speed rotation, easily leading to bending deformation, which in turn causes friction with the inner wall of the hole, resulting in wear on both the workpiece and the honing rod. Summary of the Invention

[0004] This invention provides a support device and honing equipment to solve the problem that the long overhang length of the deep hole honing rod makes it prone to deformation, causing wear on the workpiece and the honing rod.

[0005] In a first aspect, the present invention provides a support device for a honing apparatus, comprising: a support mechanism sleeved on a honing rod of the honing apparatus, the support mechanism being configured to switch between a first state and a second state; in the first state, the support mechanism locks the honing rod and moves with the honing rod to allow the support mechanism to enter the inner hole of a workpiece and contact the inner wall of the inner hole; in the second state, the support mechanism is disengaged from the honing rod to allow the honing rod to move relative to the support mechanism; an adjustment mechanism configured to control the switching of the support mechanism between the first state and the second state; and a limiting mechanism, in the second state, abutting against the support mechanism, and in the first state, disengaging from the support mechanism; the support mechanism, the adjustment mechanism, and the limiting mechanism are arranged sequentially along a first direction.

[0006] According to the above technical means, in the first state, the support mechanism locks the honing rod and extends into the inner hole together with the honing rod. The outer diameter of the support mechanism is equivalent to the inner diameter of the inner hole. The end of the honing rod is provided with a honing head. The support mechanism and the honing head work together to support the honing rod, thereby reducing the overhang length of the honing rod and reducing the deflection of the honing rod during rotation. This reduces the probability of deformation of the honing rod and helps prevent the honing rod from colliding with the inner wall of the inner hole, thereby improving the honing quality and extending the service life of the honing rod.

[0007] Furthermore, since the required length of the honing rod to extend into the workpiece varies, the support mechanism is designed to switch between a first state and a second state. This allows for adjustment of the support mechanism's position on the honing rod according to the actual machining conditions. The adjustment mechanism first switches the support mechanism to the second state, with the limiting mechanism abutting against it to maintain this state. At this point, the support mechanism is disengaged from the honing rod, allowing the honing rod to reciprocate. Once the honing rod reaches the appropriate position, the limiting mechanism disengages from the support mechanism, and the adjustment mechanism simultaneously drives the support mechanism back to the first state. This causes the support mechanism to re-lock the honing rod and follow it into the workpiece's inner hole, providing support and ensuring honing quality. This also improves the flexibility of the support device, making it suitable for machining different workpieces.

[0008] In one optional embodiment, the support mechanism includes a first support member, a second support member, and an elastic component; in a first state, the first support member and the second support member are engaged to define a receiving hole for the honing rod to pass through; in a second state, the first support member and the second support member are at least partially separated; the first support member and the second support member are connected by the elastic component, and in the second state, the elastic component generates a restoring force that drives the first support member and the second support member to engage.

[0009] Thus, the elastic component ensures that the first and second supports remain engaged in the first state, increasing the locking force between the first and second supports and the honing rod, thereby ensuring that the support mechanism can rotate and reciprocate with the honing rod. When the adjusting component applies a sufficiently large external force to the first and second supports, the first and second supports are opened, the receiving hole enlarges, and the first and second supports are disengaged from the honing rod, allowing the honing rod to move freely relative to the support mechanism. After the external force disappears, the first and second supports re-engage under the restoring force of the elastic component, thus switching back to the first state. This enables the automatic reset of the first and second supports, ensuring that the support mechanism can flexibly switch between the first and second states.

[0010] In one optional embodiment, the elastic component includes a first connector, a second connector, and a first elastic member; one end of the first support member is hinged to one end of the second support member, the other end of the first support member is provided with a first connector, the other end of the second support member is provided with a second connector, and both ends of the first elastic member are respectively connected to the first connector and the second connector; in the second state, the first elastic member is stretched.

[0011] Thus, in the second state, the first elastic element is stretched. When the external force applied by the adjusting mechanism to the support mechanism disappears, the first elastic element pulls the first and second support elements back to their original positions, thereby locking the support mechanism. This helps to ensure the stability of the connection between the support mechanism and the honing rod in the first state, ensuring that the support mechanism always moves with the honing rod, avoiding wear, improving the reliability of the honing equipment, and extending the service life of the honing rod.

[0012] In one optional embodiment, the elastic component includes two connecting bolts and two second elastic elements; two connecting grooves are symmetrically arranged at both ends of the first support member, and two bolt holes are symmetrically opened at both ends of the second support member; the connecting bolts include a bolt connecting section, an adjusting section, and a limiting section connected in sequence; the bolt connecting section passes through the bottom of the connecting groove and is bolted to the bolt hole; the second elastic element is sleeved on the adjusting section and located in the connecting groove, and both ends of the second elastic element abut against the limiting section and the bottom of the connecting groove, respectively; in the second state, the second elastic element is compressed.

[0013] Thus, the adjusting section slides into the connecting groove of the first support member. When the external force applied by the adjusting mechanism to the support mechanism disappears, the second elastic member pushes the bottom of the connecting groove and the limiting section, thereby switching the support mechanism to the first state.

[0014] In one optional embodiment, the support mechanism further includes a third support member and a fourth support member; the third support member is disposed on the outer peripheral side of the first support member, and the fourth support member is disposed on the outer peripheral side of the second support member; when the support mechanism is located in the inner hole of the workpiece, the third support member and the fourth support member are used to contact the inner wall of the inner hole.

[0015] Thus, in the first state, the third and fourth support members are in contact with the inner wall of the hole, thereby reducing the friction between the support mechanism and the workpiece while ensuring the support function of the support mechanism, preventing scratches on the inner hole, thereby improving the reliability of the support device and extending the service life of the support mechanism.

[0016] In one optional embodiment, at least one of the first support member and the second support member has a limiting groove on its outer wall; the third support member or the fourth support member is partially located within the limiting groove.

[0017] In this way, by setting the limiting groove, the third and fourth support components are positioned in both the axial and circumferential directions, which helps to ensure the stability of the connection between the third and fourth support components and the first and second support components, thereby improving the reliability of the support mechanism and extending the service life of the honing equipment.

[0018] In one optional embodiment, the adjustment mechanism includes an adjustment assembly, the adjustment assembly including an adjustment member; the third support member and the fourth support member together define an adjustment groove, the third support member being fixedly connected to the first support member, and the fourth support member being fixedly connected to the second support member; the adjustment member is located within the adjustment groove, the adjustment member at least partially abutting against the third support member and the fourth support member, and the adjustment member is configured to move relative to the adjustment groove along the first direction to drive the support mechanism to switch between the first state and the second state via the third support member and the fourth support member.

[0019] Thus, in the first state, the adjusting member is located within the adjusting groove, and the adjusting member and the adjusting groove are in stress-free contact. Moving the adjusting member relative to the adjusting groove can open the third and fourth support members, thereby applying a sufficiently large force to the support mechanism and switching it to the second state. When the adjusting member moves in the opposite direction, it separates from the adjusting groove, the external force disappears, and the support mechanism switches back to the first state under the action of the elastic component. Therefore, by controlling the position of the adjusting member relative to the adjusting groove, the position of the support mechanism on the honing rod can be adjusted, offering high flexibility. This allows the support mechanism to be adjusted at any time according to actual processing needs, which helps to expand the application range of the support device and improve its compatibility.

[0020] In one alternative embodiment, the adjusting member includes a first wedge-shaped surface, and the groove wall of the adjusting groove forms a second wedge-shaped surface, wherein the first wedge-shaped surface and the second wedge-shaped surface are in sliding engagement.

[0021] Thus, by utilizing the force-amplifying principle of the wedge surface, the axial movement of the adjusting member is converted into the radial opening movement of the adjusting groove, thereby achieving continuous and stable opening of the third and fourth supporting members, and thus enabling the support mechanism to smoothly switch to the second state. To ensure that the clamping force of the support mechanism in the first state is sufficiently large, the elastic force of the first or second elastic member is relatively large. Therefore, the sliding cooperation of the first and second wedge surfaces makes the adjustment more effortless and facilitates the rapid switching between the first and second states.

[0022] In one optional embodiment, the adjusting mechanism further includes a pressing component, which in turn includes a fixed seat and a sliding seat. The fixed seat is fitted onto the honing rod and has a clearance fit with it. The fixed seat is fixedly connected to the support mechanism, and the sliding seat is slidably fitted with the fixed seat. The adjusting member is disposed on the sliding seat. The pressing component is fixed to the base of the honing equipment and is configured to push the sliding seat toward the support mechanism so that the adjusting member moves relative to the adjusting groove.

[0023] Thus, the adjustment mechanism and the support mechanism move synchronously. In the first state, when the support mechanism follows the honing rod and moves backward in the first direction until the slide block abuts against the pressing component, it moves backward further. The pressing component pushes the slide block, and the adjustment component on the slide block slides relative to the adjustment groove. The first wedge surface and the second wedge surface slide and cooperate, thereby supporting the adjustment groove. As a result, the first support component and the second support component are taken away from the honing rod by the third support component and the fourth support component, thereby switching the support mechanism to the second state.

[0024] After switching to the second state, the supporting mechanism remains in the second state under the combined action of the limiting mechanism and the adjusting mechanism. At this time, the honing rod can continue to move forward or backward. After adjusting the honing rod to the appropriate position, the limiting mechanism no longer limits the movement, the adjusting component slides in the opposite direction, and the supporting mechanism returns to the first state, thereby realizing the position adjustment of the supporting mechanism. By coordinating the action of the adjusting mechanism with the reciprocating movement of the honing rod, the state switching and position adjustment of the supporting mechanism are realized. The operation is simple, highly flexible, and conducive to improving the response speed of the supporting mechanism.

[0025] In addition, the clearance fit between the fixed seat and the honing rod ensures that there is no interference between the fixed seat and the honing rod when the support mechanism is in the second state, thereby ensuring the smooth movement of the honing rod and preventing wear on the honing rod.

[0026] In one optional embodiment, the adjusting assembly further includes a guide rod and a third elastic element, and the slide includes a pressing surface; the guide rod extends along the first direction, one end of the guide rod passes through the fixed seat and is fixedly connected to the support mechanism, and the other end of the guide rod is slidably engaged with the pressing surface; the third elastic element is sleeved on the guide rod, and both ends of the third elastic element abut against the pressing surface and the fixed seat respectively; in the second state, the pressing assembly abuts against the pressing surface, and the third elastic element is compressed.

[0027] Thus, the fixed seat is fixed to the support mechanism via a guide rod, while the other end of the guide rod passes through the pressure surface, providing a certain guiding effect on the slide and preventing it from shifting, which helps improve the accuracy of the adjustment component. When the pressure component pushes against the pressure surface, the slide begins to slide along the guide rod, thereby driving the adjusting member to support the adjustment groove. At this time, the third elastic member is compressed, and the support mechanism maintains the second state through the limiting mechanism. When the limiting mechanism stops limiting, the slide returns to its original position under the action of the third elastic member, the adjusting member returns to its original position relative to the adjustment groove, and the support mechanism switches to the first state under the action of the elastic member. Therefore, only the limiting mechanism needs to be adjusted to achieve automatic switching of the support mechanism from the second state to the first state, with a rapid response, which helps improve the flexibility of the support mechanism's state switching.

[0028] In one optional embodiment, the adjusting assembly further includes a guide bar, and the fixing seat includes a fixing part and a sliding engagement part; the fixing part is fixedly connected to the support mechanism through the guide rod, the sliding engagement part is connected to the fixing part, the guide bar is disposed on the sliding engagement part and extends along the first direction, and the pressing surface is in clearance engagement with the guide bar.

[0029] This helps prevent interference when the slide block slides relative to the fixed seat, and the guide bar can prevent the pressure surface from shifting radially, ensuring the stability of the slide block's sliding.

[0030] In one optional embodiment, the pressing assembly includes a first mounting base, a first telescopic rod, an extension rod, and a pressing rod; the first mounting base is fixedly connected to the base of the honing equipment; the first telescopic rod extends along a second direction, one end of the first telescopic rod is connected to the first mounting base, and the other end of the first telescopic rod is connected to one end of the extension rod; the extension rod extends along a third direction, and the other end of the extension rod is provided with a first adjusting portion, in which a first sliding groove extending along the first direction is formed; the pressing rod includes a first sliding portion and a pressing portion, the first sliding portion passes through the first sliding groove and slides in cooperation with the first sliding groove, the pressing portion is provided at one end of the first sliding portion, and in the second state, the pressing portion presses against the slide block; the first direction, the second direction, and the third direction are perpendicular to each other.

[0031] Thus, when the honing rod reciprocates and rotates, the position of the pressing component remains unchanged, and the length of the first telescopic rod can be adjusted along the second direction to ensure that the pressing part and the slide are at the same height. The first sliding part of the pressing rod slides relative to the first sliding groove, thereby adjusting the pressing part to a position corresponding to the slide, which helps to ensure accurate contact between the pressing part and the slide and improves the accuracy of the support device.

[0032] In the first state, the support mechanism clamps the honing rod, and the adjusting component and the support mechanism move together with the honing rod. When the honing rod retracts to the point where the pressing part abuts against the pressing surface of the slide, the honing rod continues to retract, and the pressing part pushes the slide to slide as a fixed seat, thereby driving the adjusting component to move relative to the adjusting groove. The adjusting component opens the first and second supporting components through the third and fourth supporting components, and the support mechanism is disengaged from the honing rod, thus switching to the second state. The limiting mechanism cooperates with the adjusting mechanism to keep the support mechanism in the second state.

[0033] In one alternative embodiment, the first adjusting part further includes a first locking member, which is at least partially located within the first groove and connected to the first sliding part to lock the pressing rod to the first adjusting part.

[0034] Thus, when the first sliding part slides relative to the first groove until the position of the pressing part corresponds to the pressing surface, the position of the first sliding part can be locked by the first locking member to improve the stability of the pressing assembly and prevent displacement during the pressing part's pushing against the slide block.

[0035] In one optional embodiment, the pressing part includes a pressing bearing and a fixed shaft; the pressing bearing is rotatably connected to the fixed shaft, and in the second state, the pressing bearing abuts against the slide block, and the pressing bearing slides against the slide block.

[0036] Thus, when switching the support mechanism from the first state to the second state, the honing rod may still be rotating. That is, the support mechanism and adjusting assembly will switch from the first state to the second state as the honing rod rotates. To prevent wear caused by the adjusting assembly rotating relative to the pressing part during the switching process, the pressing part can be equipped with a rotatable pressing bearing. When the adjusting assembly rotates, the pressing bearing rotates synchronously, thereby reducing wear between the pressing part and the pressing surface of the slide, which helps extend the service life of the adjusting mechanism and reduce maintenance costs.

[0037] In one optional embodiment, the limiting mechanism includes a second mounting base, a second telescopic rod, and a limiting rod; the second mounting base is fixedly connected to the base of the honing equipment, one end of the second telescopic rod is rotatably connected to the mounting base, and the other end of the second telescopic rod is provided with a second adjusting part, and a second sliding groove is formed in the second adjusting part; the limiting rod includes a second sliding part and a limiting ball head, the second sliding part passes through the second sliding groove and slides with the second sliding groove, and the limiting ball head is provided at one end of the second sliding part. In the second state, the limiting ball head abuts against the support mechanism.

[0038] Thus, adjusting the length of the second telescopic rod can increase the height of the limiting ball head, ensuring that the height of the limiting ball head is consistent with that of the third or fourth support member of the support mechanism. By rotating the second telescopic rod, the extension direction of the limiting rod can be adjusted, thereby controlling whether the limiting ball head abuts or disengages from the support mechanism. The second sliding part slides relative to the second slide groove to adjust the position of the limiting ball head, ensuring that the limiting ball head can abut against the third or fourth support member of the support mechanism, thereby improving the accuracy of the limiting mechanism.

[0039] After the adjusting mechanism opens the support mechanism and disengages it from the honing rod, the second telescopic rod can be rotated to make the limiting ball head abut against the third or fourth support member. At this time, the contact surface of the slide is abutted by the pressing part, and the support mechanism is abutted by the limiting ball head. The pressing component and the limiting mechanism clamp the adjusting component and the support mechanism in the middle, thereby preventing the slide from resetting under the action of the third elastic element, thus keeping the support mechanism in the second state. When the honing rod moves to the appropriate position, the telescopic rod is rotated again to separate the limiting ball head from the support mechanism. At this time, under the action of the third elastic element, the slide drives the adjusting component to reset, and the support mechanism switches to the first state under the action of the elastic component. Since the limiting ball head has now deviated from the support mechanism under the action of the second telescopic rod, when the support mechanism moves forward with the honing rod, the limiting ball head will not interfere with the support mechanism. This helps ensure that the support mechanism can smoothly enter the inner hole of the workpiece and play a supporting role, thereby preventing the honing rod from deforming or wearing, and thus improving the honing accuracy and quality of the honing equipment.

[0040] In one alternative embodiment, the second adjusting part further includes a second locking member, which is at least partially located within the second groove and connected to the second sliding part to lock the limiting rod and the second adjusting part.

[0041] In this way, after the second sliding part is slid to the appropriate position, it can be locked by the second locking member to prevent the extension rod from sliding relative to the second sliding groove during the limiting process. This helps to ensure the stability of the limiting ball head and improve the reliability of the limiting mechanism.

[0042] In one optional embodiment, the limiting mechanism further includes a driving member; the driving member is connected to the second telescopic rod, and the driving member is configured to drive the second telescopic rod to rotate in the second state so that the limiting ball head abuts against the support mechanism, and to drive the second telescopic rod to rotate in the opposite direction in the first state so that the limiting ball head separates from the support mechanism.

[0043] In this way, the drive unit can control the rotation of the second telescopic rod as needed, so that the limiting ball head abuts against the third or fourth support member, keeping the support mechanism in the second state, or separating the limiting ball head from the support mechanism, switching the support mechanism to the first state. As long as the position and rotation frequency of the limiting ball head are reasonably controlled by the drive unit, the position of the support mechanism can be adjusted at any time during the reciprocating movement of the honing rod. The response is rapid and the flexibility is strong, which helps to improve the adjustment efficiency of the support device.

[0044] In a second aspect, the present invention also provides a honing apparatus, including the support device described in any one of the first aspects.

[0045] Based on the aforementioned technical means, the honing equipment can flexibly adjust the position of the support mechanism on the honing rod according to the length that the honing rod needs to extend into the inner hole of the workpiece. The honing rod includes two support points in the inner hole: the honing head and the support mechanism. This effectively reduces the overhang length of the honing rod, thereby preventing the honing rod from deforming and colliding with the inner wall of the hole. This is beneficial to improving the honing accuracy and quality of the honing equipment, while also reducing the wear of the honing rod and lowering the maintenance cost of the honing equipment.

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] As described in the background art, in related technologies, when honing equipment is running, the honing rod has only two support points: the drive unit and the honing head. Due to the large length-to-diameter ratio of deep-hole workpieces, the required overhang length of the honing rod is long, resulting in low rigidity of the honing rod. In actual processing, the honing rod exhibits significant deflection during high-speed rotation, easily causing bending deformation, which in turn leads to friction with the inner wall of the hole, resulting in wear on both the workpiece and the honing rod.

[0052] To address the aforementioned technical problems, this application provides a support device and a honing apparatus. The support device includes a support mechanism, an adjustment mechanism, and a limiting mechanism. The support mechanism can switch between a first state and a second state. In the first state, the support mechanism locks the honing rod and extends into the inner hole together with the honing rod. The outer diameter of the support mechanism is approximately equal to the inner diameter of the inner hole. A honing head is provided at the end of the honing rod. The support mechanism and the honing head together support the honing rod, thereby reducing the overhang length of the honing rod, reducing the deflection of the honing rod during rotation, and thus reducing the probability of deformation of the honing rod. This helps prevent the honing rod from colliding with the inner wall of the inner hole, thereby improving the honing quality and extending the service life of the honing rod.

[0053] Furthermore, since the required length of the honing rod to extend into the workpiece varies, the support mechanism is designed to switch between a first state and a second state. This allows for adjustment of the support mechanism's position on the honing rod according to the actual machining conditions. The adjustment mechanism first switches the support mechanism to the second state, with the limiting mechanism abutting against it to maintain this state. At this point, the support mechanism is disengaged from the honing rod, allowing the honing rod to reciprocate. Once the honing rod reaches the appropriate position, the limiting mechanism disengages from the support mechanism, and the adjustment mechanism simultaneously drives the support mechanism back to the first state. This causes the support mechanism to re-lock the honing rod and follow it into the workpiece's inner hole, providing support and ensuring honing quality. This also improves the flexibility of the support device, making it suitable for machining different workpieces.

[0054] The following is combined Figures 1 to 18 The following describes embodiments of the present invention.

[0055] According to an embodiment of the present invention, see, in one aspect, Figure 1 As shown, a support device is provided for a honing machine. The support device includes a support mechanism 100, an adjusting mechanism 200, and a limiting mechanism 300. The support mechanism 100 is sleeved on the honing rod 10 of the honing machine. The support mechanism 100 is configured to switch between a first state and a second state. In the first state, the support mechanism 100 locks the honing rod 10 and moves with the honing rod 10 so that the support mechanism 100 enters the inner hole of the workpiece 1 and contacts the inner wall of the inner hole. In the second state, the support mechanism 100 is disengaged from the honing rod 10 so that the honing rod 10 moves relative to the support mechanism 100. The adjusting mechanism 200 is configured to control the switching of the support mechanism 100 between the first state and the second state. In the second state, the limiting mechanism 300 abuts against the support mechanism 100, and in the first state, the limiting mechanism 300 is disengaged from the support mechanism 100. The support mechanism 100, the adjusting mechanism 200, and the limiting mechanism 300 are arranged sequentially along a first direction. in, Figure 1 The X-direction is the first direction.

[0056] In this embodiment, in the first state, the support mechanism 100 locks the honing rod 10 and extends into the inner hole together with the honing rod 10. The outer diameter of the support mechanism 100 is equivalent to the inner diameter of the inner hole. The end of the honing rod 10 is provided with a honing head 20. The support mechanism 100 and the honing head 20 together support the honing rod 10, thereby reducing the overhang length of the honing rod 10, reducing the deflection of the honing rod 10 during rotation, thereby reducing the probability of deformation of the honing rod 10, which helps to prevent the honing rod 10 from colliding with the inner wall of the inner hole, thereby improving the honing quality and extending the service life of the honing rod 10.

[0057] Furthermore, since the length of the honing rod 10 that needs to extend into the workpiece 1 varies, the support mechanism 100 is configured to switch between a first state and a second state. This allows the position of the support mechanism 100 on the honing rod 10 to be adjusted according to the actual processing conditions. The adjustment mechanism 200 first switches the support mechanism 100 to the second state, and the limiting mechanism 300 abuts against the support mechanism 100 to keep it in the second state. At this time, the support mechanism 100 is disengaged from the honing rod 10, and the honing rod 10 can reciprocate. When the honing rod 10 moves to the appropriate position, the limiting mechanism 300 disengages from the support mechanism 100, and at the same time, the adjustment mechanism 200 drives the support mechanism 100 to switch back to the first state, thereby causing the support mechanism 100 to lock the honing rod 10 again and follow the honing rod 10 into the inner hole of the workpiece 1, playing a supporting role, ensuring honing quality, and improving the flexibility of the support device, thus making it suitable for processing different workpieces 1, and further expanding the applicability of the honing equipment.

[0058] Furthermore, the length of the support mechanism 100 along the first direction can be set according to the length of the honing rod 10 and the length that needs to be extended into the workpiece 1. When the honing rod 10 is long, the length of the support mechanism 100 can be appropriately increased to enlarge the support surface. This helps to further improve the rigidity of the honing rod 10, prevent the honing rod 10 from deforming and making unintended contact with the inner hole, thereby improving the processing accuracy and quality of the honing equipment and enhancing its reliability. This application embodiment does not impose a specific length limit on the support structure; it can be reasonably set according to actual conditions.

[0059] In one embodiment, see Figures 1 to 6 As shown, the support mechanism 100 includes a first support member 110, a second support member 120, and an elastic component 130. In a first state, the first support member 110 and the second support member 120 are engaged to define a receiving hole for passing through the honing rod 10. In a second state, the first support member 110 and the second support member 120 are at least partially separated. The first support member 110 and the second support member 120 are connected by the elastic component 130. In the second state, the elastic component 130 generates a restoring force that drives the first support member 110 and the second support member 120 to engage.

[0060] In practical implementation, the elastic component 130 ensures that the first support member 110 and the second support member 120 remain engaged in the first state, increasing the locking force between the first support member 110 and the second support member 120 and the honing rod 10, thereby ensuring that the support mechanism 100 can rotate and reciprocate with the honing rod 10. When the adjusting component 210 applies a sufficiently large external force to the first support member 110 and the second support member 120, the first support member 110 and the second support member 120 are stretched open, the receiving hole becomes larger, thereby disengaging the first support member 110 and the second support member 120 from the honing rod 10, allowing the honing rod 10 to move freely relative to the support mechanism 100. After the external force disappears, the first support member 110 and the second support member 120 re-engage under the restoring force of the elastic component 130, thus switching back to the first state. This enables the automatic reset of the first support member 110 and the second support member 120, ensuring that the support mechanism 100 can flexibly switch between the first state and the second state.

[0061] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the elastic component 130 includes a first connector 131, a second connector 132, and a first elastic member 133; one end of the first support member 110 is hinged to one end of the second support member 120, the other end of the first support member 110 is provided with the first connector 131, the other end of the second support member 120 is provided with the second connector 132, and the two ends of the first elastic member 133 are respectively connected to the first connector 131 and the second connector 132; in the second state, the first elastic member 133 is stretched.

[0062] For example, the first support member 110 and the second support member 120 are respectively formed as a male sleeve and a female sleeve. One end of the first support member 110 is provided with a protrusion, and one end of the second support member 120 is provided with a groove that matches the shape of the protrusion. The support member is located in the groove and is hinged through the pivot 121. The other end of the first support member 110 and the other end of the second support member 120 can be provided with stepped surfaces. The first connector 131 and the second connector 132 can be bolts, which are respectively provided on two symmetrically distributed stepped surfaces. A clearance space is left between the two stepped surfaces to accommodate the first elastic member 133. In the second state, the first elastic element 133 is stretched. When the external force applied by the adjusting mechanism 200 to the support mechanism 100 disappears, the first elastic element 133 pulls the first support element 110 and the second support element 120 to reset, thereby locking the support mechanism 100. This helps to ensure the stability of the connection between the support mechanism 100 and the honing rod 10 in the first state, ensuring that the support mechanism 100 always moves with the honing rod 10, avoiding wear, improving the reliability of the honing equipment, and extending the service life of the honing rod 10.

[0063] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the elastic component 130 includes two connecting bolts 134 and two second elastic elements 135; two connecting grooves 111 are symmetrically arranged at both ends of the first support member 110, and two bolt holes are symmetrically opened at both ends of the second support member 120; the connecting bolts 134 include a bolt connecting section 1341, an adjusting section 1342, and a limiting section 1343 connected in sequence; the bolt connecting section 1341 passes through the bottom of the connecting groove 111 and is bolted to the bolt hole; the second elastic element 135 is sleeved on the adjusting section 1342 and located in the connecting groove 111, and the two ends of the second elastic element 135 abut against the limiting section 1343 and the bottom of the connecting groove 111, respectively; in the second state, the second elastic element 135 is compressed.

[0064] It should be noted that when the elastic component 130 includes two second elastic elements 135, it is necessary to ensure that the elastic coefficient and length of the two second elastic elements 135 are consistent to ensure that the elastic force on both ends of the first support member 110 is consistent in the second state, thereby ensuring that the first support member 110 can be quickly and stably pulled to engage with the second support member 120. The adjusting section 1342 slides in cooperation with the connecting groove 111 of the first support member 110. When the external force applied by the adjusting mechanism 200 to the support mechanism 100 disappears, the second elastic element 135 pushes the bottom of the connecting groove 111 and the limiting section 1343, thereby switching the support mechanism 100 to the first state.

[0065] In one embodiment, see Figures 1 to 6 , Figure 17 and Figure 18 As shown, the support mechanism 100 also includes a third support member 140 and a fourth support member 150; the third support member 140 is disposed on the outer periphery of the first support member 110, and the fourth support member 150 is disposed on the outer periphery of the second support member 120; when the support mechanism 100 is located in the inner hole of the workpiece 1, the third support member 140 and the fourth support member 150 are used to contact the inner wall of the inner hole.

[0066] It is understandable that, in order to set up the elastic component 130, the first support member 110 and the second support member 120 may be provided with structures such as connecting groove 111 and stepped surface. In order to ensure that the first support member 110 and the second support member 120 can clamp the honing rod 10 and ensure the support effect of the support mechanism 100, the first support member 110 and the second support member 120 need to be made of materials with high rigidity. In the first state, if the first support member 110 and the second support member 120 are in direct contact with the inner wall of the workpiece 1, wear may occur when the support mechanism 100 rotates and reciprocates with the honing rod 10.

[0067] Therefore, a third support member 140 and a fourth support member 150 can be provided outside the first support member 110 and the second support member 120. The third support member 140 and the fourth support member 150 can be made of materials with smooth outer surfaces, low hardness, and light weight, such as nylon and plastic parts. In the first state, the third support member 140 and the fourth support member 150 are in contact with the inner wall of the hole, thereby reducing the friction between the support mechanism 100 and the workpiece 1 while ensuring the support of the support mechanism 100, preventing scratches on the inner hole, and reducing the weight of the support mechanism 100, thereby improving the reliability of the support device and extending the service life of the support mechanism 100.

[0068] Furthermore, the third support member 140 and the fourth support member 150 can be fixed to the first support member 110 and the second support member 120 by bolts or by adhesive. This application embodiment does not limit this, as long as the third support member 140 and the fourth support member 150 are always stably connected. For example, the third support member 140 and the fourth support member 150 are detachably connected to the first support member 110 and the second support member 120 by bolts. When the third support member 140 and the fourth support member 150 are worn, they can be replaced at any time without replacing other structures in the support mechanism 100. The operation is simple and convenient, which helps to save the maintenance cost of the support device.

[0069] In one embodiment, see Figures 1 to 6 As shown, at least one of the first support member 110 and the second support member 120 has a limiting groove 112 on its outer wall; the third support member 140 or the fourth support member 150 is partially located in the limiting groove 112.

[0070] In specific implementation, by setting the limiting groove 112, the third support member 140 and the fourth support member 150 are positioned in both the axial and circumferential directions. This helps to ensure the stability of the connection between the third support member 140 and the fourth support member 150 and the first support member 110 and the second support member 120, thereby improving the reliability of the support mechanism 100 and extending the service life of the honing equipment.

[0071] In one embodiment, see Figures 1 to 10 and Figures 16 to 18As shown, the adjustment mechanism 200 includes an adjustment assembly 210, which includes an adjustment member 211. A third support member 140 and a fourth support member 150 together define an adjustment groove 141. The third support member 140 is fixedly connected to the first support member 110, and the fourth support member 150 is fixedly connected to the second support member 120. The adjustment member 211 is located within the adjustment groove 141 and at least partially abuts against the third support member 140 and the fourth support member 150. The adjustment member 211 is configured to move relative to the adjustment groove 141 in a first direction to drive the support mechanism 100 to switch between a first state and a second state via the third support member 140 and the fourth support member 150.

[0072] In this embodiment, in the first state, the adjusting member 211 is located within the adjusting groove 141, and the adjusting member 211 and the adjusting groove 141 are in stress-free contact. The movement of the adjusting member 211 relative to the adjusting groove 141 can open the third support member 140 and the fourth support member 150, thereby applying a sufficiently large force to the support mechanism 100 and switching it to the second state. When the adjusting member 211 moves in the opposite direction, the adjusting member 211 separates from the adjusting groove 141, the external force disappears, and the support mechanism 100 switches back to the first state under the action of the elastic component 130. Therefore, by controlling the position of the adjusting member 211 relative to the adjusting groove 141, the position of the support mechanism 100 on the honing rod 10 can be adjusted, offering high flexibility. This allows the support mechanism 100 to be adjusted at any time according to actual processing needs, which is beneficial for expanding the applicability of the support device and improving its compatibility.

[0073] In one embodiment, see Figures 1 to 10 and Figures 16 to 18 As shown, the adjusting member 211 includes a first wedge-shaped surface 2111, and the groove wall of the adjusting groove 141 forms a second wedge-shaped surface 1411. The first wedge-shaped surface 2111 and the second wedge-shaped surface 1411 are in sliding fit.

[0074] In practical implementation, the force-amplifying principle of the wedge surface is utilized to convert the axial movement of the adjusting member 211 into the radial opening movement of the adjusting groove 141, thereby achieving continuous and stable opening of the third support member 140 and the fourth support member 150, and thus enabling the support mechanism 100 to smoothly switch to the second state. To ensure that the clamping force of the support mechanism 100 in the first state is sufficiently large, the elastic force of the first elastic member 133 or the second elastic member 135 is relatively large. Therefore, through the sliding cooperation of the first wedge surface 2111 and the second wedge surface 1411, the adjustment is more effortless, which is conducive to achieving rapid switching between the first state and the second state.

[0075] In one embodiment, see Figures 1 to 8 and Figures 11 to 13As shown, the adjusting mechanism 200 also includes a pressing component 220, and the adjusting component 210 also includes a fixed seat 212 and a slide 213; the fixed seat 212 is used to be sleeved on the honing rod 10 and is clearance-fitted with the honing rod 10, the fixed seat 212 is fixedly connected to the support mechanism 100, the slide 213 is slidably fitted with the fixed seat 212, and the adjusting member 211 is disposed on the slide 213; the pressing component 220 is fixed to the base 30 of the honing equipment, and the pressing component 220 is configured to push the slide 213 toward the support mechanism 100 so that the adjusting member 211 moves relative to the adjusting groove 141.

[0076] Specifically, the fixed seat 212 is fixedly connected to the support mechanism 100, that is, the adjustment mechanism 200 moves synchronously with the support mechanism 100. In the first state, when the support mechanism 100 follows the honing rod 10 and moves backward in the first direction until the slide 213 abuts against the pressing component 220, it moves backward further. The pressing component 220 pushes the slide 213, and the adjustment member 211 on the slide 213 slides relative to the adjustment groove 141. The first wedge surface 2111 and the second wedge surface 1411 slide and cooperate, thereby supporting the adjustment groove 141. Thus, the first support member 110 and the second support member 120 are taken away from the honing rod 10 through the third support member 140 and the fourth support member 150, thereby switching the support mechanism 100 to the second state.

[0077] After switching to the second state, the supporting mechanism 100 remains in the second state under the combined action of the limiting mechanism 300 and the adjusting mechanism 200. At this time, the honing rod 10 can continue to move forward or backward. After the honing rod 10 is adjusted to a suitable position, the limiting mechanism 300 no longer limits the movement, the adjusting member 211 slides in the opposite direction, and the supporting mechanism 100 returns to the first state, thereby realizing the position adjustment of the supporting mechanism 100. By coordinating the action of the adjusting mechanism 200 with the reciprocating movement of the honing rod 10, the state switching and position adjustment of the supporting mechanism 100 are realized. The operation is simple, the flexibility is high, and it is beneficial to improve the response speed of the supporting mechanism 100.

[0078] In addition, the clearance fit between the fixed seat 212 and the honing rod 10 ensures that there is no interference between the fixed seat 212 and the honing rod 10 when the support mechanism 100 is in the second state, thereby ensuring the smooth movement of the honing rod 10 and preventing wear on the honing rod 10.

[0079] In one embodiment, see Figures 1 to 10As shown, the adjusting assembly 210 also includes a guide rod 214 and a third elastic element 215, and the slide 213 includes a pressing surface 2131; the guide rod 214 extends along a first direction, one end of the guide rod 214 passes through the fixed seat 212 and is fixedly connected to the support mechanism 100, and the other end of the guide rod 214 is slidably engaged with the pressing surface 2131; the third elastic element 215 is sleeved on the guide rod 214, and both ends of the third elastic element 215 abut against the pressing surface 2131 and the fixed seat 212 respectively; in the second state, the pressing assembly 220 abuts against the pressing surface 2131, and the third elastic element 215 is compressed.

[0080] It is understood that the fixed seat 212 is fixedly connected to the support mechanism 100 via the guide rod 214. Simultaneously, the other end of the guide rod 214 passes through the pressing surface 2131, thus providing a certain guiding effect on the slide 213 and preventing it from shifting, which helps improve the accuracy of the adjustment component 210. When the pressing component 220 pushes against the pressing surface 2131, the slide 213 begins to slide along the guide rod 214, thereby driving the adjusting member 211 to support the adjusting groove 141. At this time, the third elastic member 215 is compressed, and the support mechanism 100 maintains the second state through the limiting mechanism 300. When the limiting mechanism 300 no longer limits the movement, the slide is reset under the action of the third elastic member 215, the adjusting member 211 returns to its original position relative to the adjusting groove 141, and the support mechanism 100 switches to the first state under the action of the elastic component 130. Therefore, only the limit mechanism 300 needs to be adjusted to achieve automatic switching of the support mechanism 100 from the second state to the first state, which is quick and helps to improve the flexibility of the support mechanism 100 in switching states.

[0081] In one embodiment, see Figures 1 to 10 As shown, the adjustment assembly 210 also includes a guide bar 216, and the fixed seat 212 includes a fixed part 2121 and a sliding fit part 2122; the fixed part 2121 is fixedly connected to the support mechanism 100 through the guide rod 214, the sliding fit part 2122 is connected to the fixed part 2121, the guide bar 216 is disposed on the sliding fit part 2122 and extends along the first direction, and the pressing surface 2131 is in clearance fit with the guide bar 216.

[0082] It is understandable that the guide bar 216 can be symmetrically arranged on the outer surface of the sliding mating part 2122. The guide bar 216 extends along the first direction. The slide 213, the fixed part 2121, and the guide bar 216 are all clearance fit, which helps to prevent interference when the slide 213 slides relative to the fixed part 212. At the same time, the guide bar 216 can prevent the pressing surface 2131 from shifting radially, ensuring the stability of the slide 213 sliding.

[0083] In one embodiment, see Figures 1 to 8 and Figures 11 to 13As shown, the pressing assembly 220 includes a first mounting base 221, a first telescopic rod 222, an extension rod 223, and a pressing rod 224; the first mounting base 221 is used to be fixedly connected to the base 30 of the honing equipment; the first telescopic rod 222 extends along a second direction, one end of the first telescopic rod 222 is connected to the first mounting base 221, and the other end of the first telescopic rod 222 is connected to one end of the extension rod 223; the extension rod 223 extends along a third direction, and the other end of the extension rod 223 is provided with a first adjustment part 2. 231, a first sliding groove 2231a extending along a first direction is formed in the first adjusting part 2231; the pressing rod 224 includes a first sliding part 2241 and a pressing part 2242, the first sliding part 2241 passes through the first sliding groove 2231a and slides in cooperation with the first sliding groove 2231a, the pressing part 2242 is provided at one end of the first sliding part 2241, and in the second state, the pressing part 2242 presses against the slide block 213; the first direction, the second direction and the third direction are perpendicular to each other. Figure 2 and Figure 3 The X direction is the first direction, the Z direction is the second direction, and the Y direction is the third direction.

[0084] In practical implementation, the first mounting base 221 is fixedly connected to the base 30. Therefore, when the honing rod 10 performs reciprocating and rotating movements, the position of the pressing component 220 remains unchanged. The length of the first telescopic rod 222 can be adjusted along the second direction to ensure that the pressing part 2242 and the slide 213 are at the same height. The first sliding part 2241 of the pressing rod 224 slides relative to the first sliding groove 2231a, thereby adjusting the pressing part 2242 to a position corresponding to the slide 213. This helps to ensure accurate contact between the pressing part 2242 and the slide 213, improving the accuracy of the support device.

[0085] In the first state, the support mechanism 100 clamps the honing rod 10, and the adjusting component 210 moves together with the support mechanism 100 along with the honing rod 10. When the honing rod 10 retracts to the point where the pressing part 2242 abuts against the pressing surface 2131 of the slide block 213, the honing rod 10 continues to retract, and the pressing part 2242 pushes the slide block 213 to slide, which is equivalent to the fixed seat 212, thereby driving the adjusting component 211 to move relative to the adjusting groove 141. The adjusting component 211 opens the first supporting component 110 and the second supporting component 120 through the third supporting component 140 and the fourth supporting component 150, and the support mechanism 100 is disengaged from the honing rod 10, thereby switching to the second state. The limiting mechanism 300 cooperates with the adjusting mechanism 200 to keep the support mechanism 100 in the second state.

[0086] In one embodiment, see Figures 1 to 8 and Figures 11 to 13As shown, the first adjustment part 2231 also includes a first locking member 2231b, which is at least partially located in the first slide groove 2231a and connected to the first sliding part 2241 to lock the pressure rod 224 to the first adjustment part 2231.

[0087] Specifically, when the first sliding part 2241 slides relative to the first sliding groove 2231a until the position of the pressing part 2242 corresponds to the pressing surface 2131, the position of the first sliding part 2241 can be locked by the first locking member 2231b to improve the stability of the pressing assembly 220 and prevent displacement during the process of the pressing part 2242 pushing against the slide block 213. Furthermore, a third locking member 2221 can be provided on the telescopic rod. After the first telescopic rod 222 is adjusted to a suitable length, the third locking member 2221 locks it to ensure that the height of the pressing part 2242 does not change, which helps to further improve the stability of the pressing assembly 220 and thus improve the overall reliability of the support device.

[0088] In one embodiment, see Figures 1 to 8 and Figures 11 to 13 As shown, the pressing part 2242 includes a pressing bearing 2242a and a fixed shaft 2242b; the pressing bearing 2242a is rotatably connected to the fixed shaft 2242b. In the second state, the pressing bearing 2242a abuts against the slide 213, and the pressing bearing 2242a and the slide 213 are in sliding engagement.

[0089] It is understandable that when the support mechanism 100 is switched from the first state to the second state, the honing rod 10 may still be rotating. That is, the support mechanism 100 and the adjusting component 210 will switch from the first state to the second state as the honing rod 10 rotates. To prevent wear caused by the rotation of the adjusting component 210 relative to the pressing part 2242 during the switching process, the pressing part 2242 can be equipped with a rotatable pressing bearing 2242a. When the adjusting component 210 rotates, the pressing bearing 2242a can rotate synchronously, thereby reducing the wear between the pressing part 2242 and the pressing surface 2131 of the slide 213, which helps to extend the service life of the adjusting mechanism 200 and reduce maintenance costs.

[0090] In one embodiment, see Figures 1 to 8 and Figures 11 to 15As shown, the limiting mechanism 300 includes a second mounting base 310, a second telescopic rod 320, and a limiting rod 330. The second mounting base 310 is fixedly connected to the base 30 of the honing equipment. One end of the second telescopic rod 320 is rotatably connected to the mounting base, and the other end of the second telescopic rod 320 is provided with a second adjusting part 321. A second sliding groove 3211 is opened in the second adjusting part 321. The limiting rod 330 includes a second sliding part 331 and a limiting ball head 332. The second sliding part 331 passes through the second sliding groove 3211 and slides in cooperation with the second sliding groove 3211. The limiting ball head 332 is located at one end of the second sliding part 331. In the second state, the limiting ball head 332 abuts against the support mechanism 100.

[0091] In this embodiment, since the third support member 140 and the fourth support member 150 of the support mechanism 100 are soft support structures, in the second state, the limiting ball head 332 can abut against the third support member 140 or the fourth support member 150, which helps to increase the limiting resistance of the limiting ball head 332 to the support mechanism 100 and ensure the limiting effect. Adjusting the length of the second telescopic rod 320 can increase the height of the limiting ball head 332, ensuring that the height of the limiting ball head 332 is consistent with that of the third support member 140 or the fourth support member 150 of the support mechanism 100. By rotating the second telescopic rod 320, the extension direction of the limiting rod 330 can be adjusted, thereby controlling the abutment or disengagement of the limiting ball head 332 from the support mechanism 100. The second sliding part 331 slides relative to the second sliding groove 3211 to adjust the position of the limiting ball head 332, ensuring that the limiting ball head 332 can abut against the third support member 140 or the fourth support member 150 of the support mechanism 100, thereby improving the accuracy of the limiting mechanism 300.

[0092] Specifically, when the adjusting mechanism 200 opens the support mechanism 100, disengaging it from the honing rod 10, the second telescopic rod 320 can be rotated to make the limiting ball head 332 abut against the third support member 140 or the fourth support member 150. At this time, the contact surface of the slide 213 is abutted by the pressing part 2242, and the support mechanism 100 is abutted by the limiting ball head 332. The pressing component 220 and the limiting mechanism 300 clamp the adjusting component 210 and the support mechanism 100 in the middle, thereby preventing the slide 213 from resetting under the action of the third elastic member 215, thus keeping the support mechanism 100 in the second state. When the honing rod 10 moves to the appropriate position, the telescopic rod is rotated again to separate the limiting ball head 332 from the support mechanism 100. At this time, under the action of the third elastic member 215, the slide 213 drives the adjusting member 211 to reset, and the support mechanism 100 switches to the first state under the action of the elastic component 130. Since the limiting ball head 332 has deviated from the support mechanism 100 under the drive of the second telescopic rod 320, when the support mechanism 100 moves forward with the honing rod 10, the limiting ball head 332 will not interfere with the support mechanism 100. This helps to ensure that the support mechanism 100 can smoothly enter the inner hole of the workpiece 1 and play a supporting role, thereby preventing the honing rod 10 from deforming or wearing, and thus improving the honing accuracy and quality of the honing equipment.

[0093] For specific implementation details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 14 and Figure 15 As shown, a mounting groove 311 can be formed on the second mounting base 310. A first plane bearing 312, a radial bearing 313, a second plane bearing 314, an end cap 315, and a fixing bolt 316 are arranged in the mounting groove 311. The second telescopic rod 320 is partially inserted into the mounting groove 311 and fixed in the mounting groove 311 by the fixing bolt 316 and the end cap 315. The first plane bearing 312, the radial bearing 313, and the second plane bearing 314 realize the rotatable connection between the second telescopic rod 320 and the second mounting base 310. Of course, the specific structure of the second mounting base 310 and the second telescopic rod 320 is not limited in this embodiment and can be reasonably set according to the actual situation.

[0094] In one embodiment, see Figure 1 , Figure 2 , Figure 14 and Figure 15 As shown, the second adjustment part 321 also includes a second locking member 3212, which is at least partially located in the second slide groove 3211 and connected to the second sliding part 331 to lock the limiting rod 330 and the second adjustment part 321.

[0095] Understandably, after the second sliding part 331 is slid to the appropriate position, it can be locked by the second locking member 3212 to prevent the second sliding part 331 from sliding relative to the second slide groove 3211 during the limiting process. This helps to ensure the stability of the limiting ball head 332 and improve the reliability of the limiting mechanism 300. Similarly, a fourth locking member 322 can also be provided on the second telescopic rod 320 to lock the length of the second telescopic rod 320.

[0096] In one embodiment, see Figures 1 to 6 , Figure 14 and Figure 15 As shown, the limiting mechanism 300 also includes a driving member 340; the driving member 340 is connected to the second telescopic rod 320, and the driving member 340 is configured to drive the second telescopic rod 320 to rotate in a second state so that the limiting ball head 332 abuts against the support mechanism 100, and to drive the second telescopic rod 320 to rotate in the opposite direction in a first state so that the limiting ball head 332 separates from the support mechanism 100.

[0097] In practical implementation, the drive unit 340 can control the rotation of the second telescopic rod 320 as needed, so that the limiting ball head 332 abuts against the third support member 140 or the fourth support member 150, keeping the support mechanism 100 in the second state, or separating the limiting ball head 332 from the support mechanism 100, switching the support mechanism 100 to the first state. As long as the position and rotation frequency of the limiting ball head 332 are reasonably controlled by the drive unit 340, the position of the support mechanism 100 can be adjusted at any time during the reciprocating movement of the honing rod 10. The response is rapid and the flexibility is strong, which is conducive to improving the adjustment efficiency of the support device.

[0098] The driving component 340 can be an electromagnet driver, a hydraulic cylinder driver, or a pneumatic cylinder driver, etc. This application embodiment does not limit this, as long as the driving component 340 can drive the second telescopic rod 320 to rotate.

[0099] According to an embodiment of the present invention, on the other hand, see also... Figure 1 As shown, a honing apparatus is also provided, including any of the aforementioned support devices.

[0100] It should be noted that the specific structure and working principle of the support device have been described in detail in the above embodiments, and will not be repeated here.

[0101] In this embodiment, the honing equipment can flexibly adjust the position of the support mechanism 100 on the honing rod 10 according to the length that the honing rod 10 needs to extend into the inner hole of the workpiece 1. The honing rod 10 includes two support points in the inner hole: the honing head 20 and the support mechanism 100. This effectively reduces the overhang length of the honing rod 10, thereby preventing the honing rod 10 from deforming and colliding with the inner wall of the hole. This is beneficial to improving the honing accuracy and quality of the honing equipment, while reducing the wear of the honing rod 10 and lowering the maintenance cost of the honing equipment.

[0102] In summary, the support device provided in this application embodiment has the support mechanism 100 locked onto the honing rod 10 in the first state, and enters the inner hole of the workpiece 1 together with the honing rod 10. Together with the honing head 20, it supports the honing rod 10, shortens the overhang length of the honing rod 10, thereby preventing the honing rod 10 from deforming and colliding with the inner wall of the hole, causing wear. This is beneficial to improving the honing quality of the honing equipment, while reducing the wear of the honing rod 10 and lowering maintenance costs. Depending on the depth of the inner hole of workpiece 1, the position of the support mechanism 100 on the honing rod 10 needs to be adjusted. Specifically, the honing rod 10 first drives the support mechanism 100 to retract until the slide 213 of the adjusting component 210 abuts against the pressing component 220. As the honing rod 10 continues to retract, the slide 213 slides relative to the fixed seat 212, and the adjusting component 211 on the slide 213 slides relative to the adjusting groove 141 of the support mechanism 100, thus supporting the support mechanism 100 and disengaging the honing rod 10, switching to the second state. At the same time, the limiting ball head 332 of the limiting mechanism 300 rotates to abut against the support mechanism 100, so that the support mechanism 100 remains in the second state. At this time, the honing rod 10 can reciprocate relative to the support mechanism 100 to adjust the position of the support mechanism 100 relative to the honing rod 10. After reaching the appropriate position, the limiting ball head 332 rotates in the opposite direction and separates from the support mechanism 100. The slide block 213 drives the adjusting member 211 to reset under the action of the third elastic member 215. The support mechanism 100 switches back to the first state under the action of the elastic component 130, re-clamps the honing rod 10, and moves with the honing rod 10, thereby realizing the adjustment of the position of the support mechanism 100.

[0103] Therefore, this embodiment of the application prevents wear between the honing rod 10 and the workpiece 1 by setting a support device, thereby improving the honing quality. The support device can flexibly adjust the position of the support mechanism 100 on the honing rod 10 by adjusting the position of the limit head in coordination with the movement of the honing rod 10, thereby adapting to different types of workpieces 1, which is beneficial to expanding the application range of the support device and improving the compatibility of the support device.

[0104] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
