Description
Technical Field
[0001] This application belongs to the technical field of lathes, and particularly relates to an auxiliary alignment tool for a lathe. Background Art
[0002] A lathe is a machine tool that uses a turning tool to perform turning operations on a rotating workpiece. Whether it is an ordinary lathe or a CNC lathe, the workpiece needs to be aligned when being clamped, so that the rotation center of the lathe coincides with the rotation center of the workpiece.
[0003] In the related art, in order to facilitate the alignment of the workpiece, an alignment tool is usually provided on the turret of the lathe. The alignment tool includes an alignment rod provided on the turret and a bearing rotatably connected to the alignment rod. When aligning the workpiece, the alignment rod needs to be adjusted so that the outer peripheral surface of the bearing abuts against the peripheral surface or end face of the workpiece, and then the workpiece is driven to rotate so that the bearing rotates following the workpiece under the action of the peripheral surface of the workpiece. If there is a deviation in the installation position of the workpiece, during the rotation of the workpiece, the outer peripheral surface of the bearing will be separated from the peripheral surface or end face of the workpiece, so that the bearing cannot rotate synchronously with the workpiece. At this time, the staff needs to adjust the workpiece again until the bearing rotates following the workpiece in real time during the rotation of the workpiece. Then, due to the different sizes of the workpieces, the relative position of the alignment rod and the turret also needs to be adjusted when clamping different workpieces, which affects the alignment efficiency of the workpiece. Summary of the Utility Model
[0004] This application provides an auxiliary alignment tool for a lathe to improve the alignment efficiency of the workpiece.
[0005] The technical solution adopted by this application is as follows:
[0006] An auxiliary alignment tool for a lathe includes a body provided on the turret, an adjusting member provided on the body, and a rolling body rotatably connected to the adjusting member. The adjusting member can move relative to the body so that the position of the rolling body can change to abut against different workpieces.
[0007] By adopting the above technical solution, when using the auxiliary alignment tool to assist in aligning the workpiece, first install the body on the turret of the lathe, and then adjust the adjusting member so that the relative position between the rolling body and the body changes until the rolling body can abut against the peripheral surface of the workpiece. Then rotate the body so that the rolling body rotates following the workpiece. If during the rotation of the workpiece, there is a position where the rolling body cannot rotate synchronously with the workpiece, it means that there is a deviation between the rotation center of the workpiece and the rotation center of the lathe. At this time, adjust the workpiece again until the rolling body rotates following the workpiece.
[0008] Since the adjusting member can move relative to the main body, when aligning different workpieces, only the adjusting member needs to be adjusted, and there is no need to adjust the relative position between the main body and the square tool rest, so as to improve the alignment efficiency of the workpiece. At the same time, the alignment range of the auxiliary alignment tool can be increased to increase the flexibility of the auxiliary alignment tool.
[0009] Optionally, the main body is provided with a sliding groove, the adjusting member includes a sliding section slidably connected to the sliding groove and a connecting section exposed outside the sliding groove, and the rolling body is connected to the connecting section.
[0010] By adopting the above technical solution, when adjusting the rolling body, the adjusting member is slid, and then the sliding section slides relative to the sliding groove, so that the relative position between the rolling body and the main body changes, so as to realize the adjustment of the rolling body. In this process, only the adjusting member needs to be slid, so as to reduce the adjustment difficulty of the rolling body and further improve the alignment efficiency of the workpiece.
[0011] Optionally, the main body is provided with a reference scale, and the sliding section is provided with an indicating arrow pointing to the reference scale.
[0012] By adopting the above technical solution, when the adjusting member is slid, the sliding section drives the indicating arrow to move, and then the indicating arrow moves relative to the reference scale, so that the scale indicated by the indicating arrow changes. And the staff can determine the adjusted distance of the rolling body by referring to the relative change distance between the indicating arrow and the reference scale, so as to achieve the effect of facilitating the staff to accurately adjust the rolling body.
[0013] Optionally, the main body is provided with a hidden groove, the reference scale is located in the hidden groove, and at least part of the indicating arrow is located in the hidden groove.
[0014] By adopting the above technical solution, since the reference scale is located in the hidden groove and at least part of the indicating arrow is located in the hidden groove, the reference scale and the indicating arrow do not protrude from the main body, so as to avoid the situation that the reference scale may be worn, and at the same time, the situation that the indicating arrow is easily damaged can also be avoided, so as to increase the service life of the auxiliary alignment tool.
[0015] Optionally, the main body is provided with a transparent cover plate covering the hidden groove.
[0016] By adopting the above technical solution, since the main body is provided with a transparent cover plate covering the hidden groove, on the one hand, the staff can observe the relative position between the indicating arrow and the reference scale through the transparent cover plate, and on the other hand, the transparent cover plate can block dust from the hidden groove to avoid the situation that dust enters the hidden groove and causes the indicating arrow to get stuck, so as to ensure the service life of the auxiliary alignment tool.
[0017] Optionally, the body is threadedly connected with a locking rod, and the locking rod has a locking position where it abuts against the sliding section and an unlocking position where it is separated from the sliding section.
[0018] By adopting the above technical solution, when adjusting the rolling element, first rotate the locking rod so that the locking rod moves from the locking position to the unlocking position, and then the locking rod is separated from the sliding section. After adjusting the rolling element to the set position, rotate the locking rod in the reverse direction so that the locking rod moves from the unlocking position to the locking position, thereby enabling the locking rod to abut against the sliding section to complete the adjustment of the rolling element. By locking the adjusting member with the locking rod, the stability of the adjusting member is increased, and further the accuracy of aligning the workpiece is increased.
[0019] Optionally, the sliding section is provided with a waist-shaped groove whose length direction is parallel to the sliding direction of the sliding section, and at least part of the locking rod is located in the waist-shaped groove.
[0020] By adopting the above technical solution, since the length direction of the waist-shaped groove is parallel to the sliding direction of the sliding section and at least part of the locking rod is located in the waist-shaped groove, the locking rod and the groove wall of the waist-shaped groove can be in a stop fit, so that the locking rod can limit the sliding range of the adjusting member to avoid the situation that the sliding section may be separated from the body, and further increase the connection stability between the adjusting member and the body.
[0021] Optionally, the locking rod is arranged at one end of the body close to the rolling element.
[0022] By adopting the above technical solution, since the locking rod is arranged at one end of the body close to the rolling element, the adjustable range of the adjusting member is increased, so as to further increase the adjustable range of the rolling element and further increase the alignment range of the auxiliary alignment tool.
[0023] Optionally, the outer peripheral surface of the rolling element is provided with a corrugated groove, and the corrugated groove extends along the circumferential direction of the rolling element.
[0024] By adopting the above technical solution, since the outer peripheral surface of the rolling element is provided with a corrugated groove and the corrugated groove extends along the circumferential direction of the rolling element, when the rolling element rotates following the workpiece, the relative position between the corrugated groove and the workpiece changes, so that the staff can check whether the rolling element rotates synchronously with the workpiece to achieve the effect of accurately aligning the workpiece.
[0025] Optionally, multiple color bands are arranged in the corrugated groove, and the colors of adjacent two color bands are different.
[0026] By adopting the above technical solution, since there are multiple color bands arranged in the corrugated groove and the colors of adjacent two color bands are different, it makes the rolling body more obvious when rotating following the workpiece, so as to further achieve the effect of facilitating the staff to check whether the rolling body rotates synchronously with the workpiece, and further improve the accuracy of workpiece alignment.

The adjusting member can move relative to the body, so that the position of the rolling body can change to abut against different workpieces. Since the adjusting member can move relative to the body, when aligning different workpieces, only the adjusting member needs to be adjusted, and there is no need to adjust the relative position between the body and the square tool post, so as to improve the alignment efficiency of the workpiece. At the same time, the alignment range of the auxiliary alignment tool can be increased to increase the flexibility of the auxiliary alignment tool.
[0029] 2. The body in this application is provided with a sliding groove. The adjusting member includes a sliding end slidably connected to the sliding groove and a connecting section exposed outside the sliding groove. The rolling body is connected to the connecting section. When adjusting the rolling body, the adjusting member is slid, and then the sliding section slides relative to the sliding groove, so that the relative position between the rolling body and the body changes to realize the adjustment of the rolling body.

[0043] Referring to Figures 1 to 4 , an auxiliary alignment tool for a lathe is disclosed, including a body 1 provided on a turret, an adjusting member 2 provided on the body 1, and a rolling body 3 rotatably connected to the adjusting member 2. The adjusting member 2 can move relative to the body 1 so that the position of the rolling body 3 can change to abut against different workpieces.
[0044] When using the auxiliary alignment tool to assist in aligning a workpiece, first install the body 1 on the turret of the lathe, and then adjust the adjusting member 2 so that the relative position between the rolling body 3 and the body 1 changes until the rolling body 3 can abut against the circumferential surface of the workpiece. Then rotate the body 1 so that the rolling body 3 follows the rotation of the workpiece. If there is a position where the rolling body 3 cannot rotate synchronously with the workpiece during the rotation of the workpiece, it means that there is a deviation between the rotation center of the workpiece and the rotation center of the lathe. At this time, adjust the workpiece again until the rolling body 3 rotates synchronously with the workpiece in real time.
[0045] Since the adjusting member 2 can move relative to the body 1, when aligning different workpieces, only the adjusting member 2 needs to be adjusted, and there is no need to adjust the relative position between the body 1 and the turret, so as to improve the alignment efficiency of the workpiece, and at the same time, the alignment range of the auxiliary alignment tool can be increased to increase the flexibility of the auxiliary alignment tool.
[0046] This application does not specifically limit the structure of the rolling body 3. Preferably, referring to Figure 1 and Figure 4 , the rolling body 3 is a bearing to reduce the resistance when the rolling body 3 rotates, so as to ensure that the rolling body 3 can rotate synchronously with the workpiece when it contacts the workpiece. In other embodiments, the rolling body 3 can also be a rolling wheel.
[0047] In a preferred embodiment, referring to Figure 2 , Figure 3 and Figure 4, the body 1 is provided with a sliding groove 11. The adjusting member 2 includes a sliding section 21 slidably connected to the sliding groove 11 and a connecting section 22 exposed outside the sliding groove 11. The rolling body 3 is connected to the connecting section 22.
[0048] When adjusting the rolling body 3, the adjusting member 2 is slid, so that the sliding section 21 and the sliding groove 11 slide relative to each other, so that the relative position between the rolling body 3 and the body 1 changes, so as to realize the adjustment of the rolling body 3. In this process, only the adjusting member needs to be slid, so as to reduce the adjustment difficulty of the rolling body 3, and further improve the alignment efficiency of the workpiece.
[0049] Preferably, referring to Figure 1 , Figure 2 and Figure 4 , a pin shaft 221 is provided on the connecting section 22, and the rolling body 3 is sleeved on the pin shaft 221, so as to realize the rotational connection of the rolling body 3 to the connecting section 22.
[0050] The structure of the sliding section 21 of the present application is not specifically limited. Preferably, the cross-section of the sliding section 21 perpendicular to its own length direction is an isosceles trapezoid, and the sliding groove 11 is adapted to the sliding section 21, so as to increase the connection stability between the adjusting member 2 and the body 1, and further increase the alignment effect of the auxiliary alignment tool on the workpiece. In other embodiments, the sliding section 21 may also be T-shaped in cross-section perpendicular to its own length direction.
[0051] In a preferred embodiment, referring to Figure 1 and Figure 3 , the body 1 is provided with a reference scale 12, and the sliding section 21 is provided with an indicating arrow 211 pointing to the reference scale 12. When sliding the adjusting member, the sliding section 21 drives the indicating arrow 211 to move, so that the indicating arrow 211 and the reference scale 12 move relative to each other, so that the scale indicated by the indicating arrow 211 changes, and the staff can determine the adjusted distance of the rolling body 3 by referring to the relative change distance between the indicating arrow 211 and the reference scale 12, so as to achieve the effect of facilitating the staff to accurately adjust the rolling body 3.
[0052] The structure of the reference scale 12 of the present application is not specifically limited. Preferably, the reference scale 12 is a scale line engraved or printed on the body 1, so as to reduce the production cost of the auxiliary alignment tool. In other embodiments, the reference scale 12 may also be a scale ruler with scale lines.
[0053] The present application does not specifically limit the structure of the indicating arrow 211. Preferably, the indicating arrow 211 is a strip-shaped structure provided on the sliding section 21, and the end of the strip-shaped structure is pointed and points to the reference scale 12, so as to facilitate the staff to view the relative position of the indicating arrow 211 and the reference scale 12. In other embodiments, the indicating arrow 211 can also be an arrow engraved or printed on the sliding section 21.
[0054] Further, referring to Figure 2 and Figure 3 , the main body 1 is provided with a hidden groove 13, the reference scale 12 is located in the hidden groove 13, and at least part of the indicating arrow 211 is located in the hidden groove 13.
[0055] Since the reference scale 12 is located in the hidden groove 13 and at least part of the indicating arrow 211 is located in the hidden groove 13, the reference scale 12 and the indicating arrow 211 do not protrude from the main body 1, so as to avoid possible wear of the reference scale 12, and at the same time avoid the situation that the indicating arrow 211 is easily damaged, so as to increase the service life of the auxiliary alignment tool.
[0056] Furthermore, the main body 1 is provided with a transparent cover plate covering the hidden groove 13. On the one hand, it enables the staff to observe the relative position of the indicating arrow 211 and the reference scale 12 through the transparent cover plate. On the other hand, the transparent cover plate can prevent dust from entering the hidden groove 13, so as to avoid the situation that the indicating arrow 211 is stuck due to dust entering the hidden groove 13, so as to ensure the service life of the auxiliary alignment tool.
[0057] The present application does not specifically limit the structure of the transparent cover plate. Preferably, the transparent cover plate is a plate-shaped structure made of transparent resin to increase the service life of the transparent cover plate. In other embodiments, the transparent cover plate can also be a plate-shaped structure cut from glass.
[0058] In a preferred embodiment, referring to Figure 2 and Figure 3 , the main body 1 is threadedly connected with a locking rod 14, and the locking rod 14 has a locking position against the sliding section 21 and an unlocking position separated from the sliding section 21.
[0059] When adjusting the rolling element 3, first rotate the locking rod 14 to make the locking rod 14 move from the locking position to the unlocking position, and then separate the locking rod 14 from the sliding section 21. After adjusting the rolling element 3 to the set position, rotate the locking rod 14 in the reverse direction to make the locking rod 14 move from the unlocking position to the locking position, so that the locking rod 14 abuts against the sliding section 21 to complete the adjustment of the rolling element 3. By locking the adjusting member 2 with the locking rod 14, the stability of the adjusting member 2 is increased, and further the accuracy of aligning the workpiece is increased.
[0060] Preferably, referring to Figure 2 and Figure 3 , the locking rod 14 has a locking end that can abut against the sliding section 21 and an operating end opposite to the locking end. The operating end is located outside the main body 1, and an operating block 141 is provided at the operating end. When rotating the locking rod 14, it is only necessary to rotate the operating block 141, which increases the contact area between the staff and the locking rod 14, so as to facilitate the staff to rotate the locking rod 14.
[0061] Furthermore, referring to Figure 4 , the sliding section 21 is provided with an elongated slot 222 whose length direction is parallel to the sliding direction of the sliding section 21. At least a part of the locking rod 14 is located in the elongated slot 222, and then the locking rod 14 and the slot wall of the elongated slot 222 can be in a stop fit, so that the locking rod 14 can limit the sliding range of the adjusting member 2 to avoid the situation that the sliding section 21 may be separated from the main body 1, thereby increasing the connection stability between the adjusting member 2 and the main body 1.
[0062] The present application does not make specific limitations on the setting of the locking rod 14. Preferably, referring to Figure 2 , the locking rod 14 is provided at one end of the main body 1 close to the rolling element 3, thereby increasing the adjustable range of the adjusting member 2, further increasing the adjustable range of the rolling element 3, and further increasing the alignment range of the auxiliary alignment tool. In other embodiments, the locking rod 14 can also be provided at the middle position in the length direction of the main body 1.
[0063] In a preferred embodiment, referring to Figure 2 and Figure 3 , the outer peripheral surface of the rolling element 3 is provided with a corrugated groove 31, and the corrugated groove 31 extends along the circumferential direction of the rolling element 3. Then, when the rolling element 3 rotates following the workpiece, the relative position between the corrugated groove 31 and the workpiece changes, so that the staff can check whether the rolling element 3 rotates synchronously with the workpiece, so as to achieve the effect of accurately aligning the workpiece.
[0064] Furthermore, multiple color bands are provided in the corrugated groove 31, and the colors of adjacent two color bands are different, which makes it more obvious when the rolling element 3 rotates following the workpiece, so as to further achieve the effect of facilitating the staff to check whether the rolling element 3 rotates synchronously with the workpiece, and further improving the accuracy of aligning the workpiece.
[0065] The present application does not make specific limitations on the structure of the color band. Preferably, the color band can be formed by dyes painted in the corrugated groove 31 to reduce the production cost of the auxiliary alignment tool. In other embodiments, the color band can also be a corrugated ring structure sleeved on the corrugated groove 31, and the corrugated ring structure has multiple colors along its circumferential direction.
