Description

Technical Field

[0001] This application relates to the technical field of machining apparatus for mechanical parts, and in particular to a rotating shaft machining apparatus. Background Technology

[0002] A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is mainly used in the structure of the mechanical industry. The main function of a shaft is to support rotating parts and transmit motion and power. Before a shaft is put on the market, it needs to be processed. As it is a relatively precise mechanical part, it requires many processing steps, including grinding and cutting the surface.

[0003] In conventional technology, grinding and cutting equipment for rotating shaft surfaces includes a machine base for clamping the rotating shaft to be processed, the machine base and the rotating shaft to be processed rotating coaxially and driving the rotating shaft to be processed to rotate, and a grinding tool that can move relative to the rotating shaft to grind the outer wall of the rotating shaft to be processed. However, although the machine base can automatically clamp the workpiece and the grinding tool can automatically perform the grinding operation, in the above solution, operators still need to start and stop the equipment to install the rotating shaft to be processed and remove the rotating shaft after processing, which affects work efficiency. Utility Model Content

[0004] In order to achieve automatic loading and unloading, thereby improving the working efficiency of the equipment, this application provides a shaft processing device.

[0005] This application provides a shaft machining device, which adopts the following technical solution:

[0006] A shaft machining apparatus, comprising:

[0007] Machine tool;

[0008] A feeding mechanism, the feeding mechanism including a conveyor track for sequentially conveying the rotating shafts to be processed;

[0009] A clamping disk is rotatably mounted on the machine base for clamping a rotating shaft to be processed. A first drive source for driving the clamping disk to rotate is provided on the machine base.

[0010] A transfer component, which is movable on the machine platform, is used to move the shaft to be processed at the outlet end of the conveyor track to the clamping plate so that it can be fixed by the clamping plate;

[0011] A grinding tool holder, movable on the machine base, includes a grinding tool for abutting against the outer wall of the shaft to be processed.

[0012] The feeding track is inclined and can be moved to the bottom of the clamping plate to allow the rotating shaft that falls from the clamping plate to move.

[0013] By adopting the above technical solution, during operation, the conveyor track of the feeding mechanism can sequentially transport the shafts to be processed. The transfer component moves the shafts to be processed from the outlet of the conveyor track to the clamping plate and fixes them there. At this time, the clamping plate is driven to rotate by the first drive source, and the grinding tool holder moves and grinds and cuts the outer wall of the shaft to be processed by the grinding tool. After completion, the grinding tool holder is removed, and the clamping plate no longer clamps the shaft to be processed, so that the shaft to be processed can be unloaded through the unloading track, thereby realizing the function of automatic loading and unloading and greatly improving work efficiency.

[0014] Optionally, the clamping disk is coaxially formed with a clamping groove for inserting the rotating shaft to be processed. A clamping member for clamping the rotating shaft to be processed is slidably disposed in the clamping groove, and an ejector member for ejecting the rotating shaft to be processed out of the clamping groove after the clamping member releases the rotating shaft to be processed.

[0015] By adopting the above technical solution, after the shaft to be processed is inserted into the clamping groove, it can be clamped and fixed by the clamping component, so that the shaft to be processed can be rotated when the clamping plate rotates. When the clamping component no longer clamps the shaft to be processed, the shaft to be processed can be ejected by the ejector component, which facilitates the unloading of the shaft to be processed and the grinding operation of the next shaft to be processed.

[0016] Optionally, an installation groove is provided on the inner wall of the clamping groove away from the opening, and the ejector is an elastic member with one end connected to the inner wall of the installation groove and the other end extending out of the installation groove.

[0017] By adopting the above technical solution, when the shaft to be processed is clamped and fixed by the clamping member, the elastic member can be compressed into the mounting groove and store elastic potential energy. When the clamping member no longer fixes the shaft to be processed, the elastic member resets, thereby pushing the shaft to be processed out of the clamping groove.

[0018] Optionally, the conveying track is provided with a feeding trough for the rotating shaft to be processed to move. The feeding trough passes through the bottom of the conveying track to form a discharge port. The machine base is provided with a second drive source for driving the rotating shaft to be processed on the rotating component to move in a direction parallel to the axis of the clamping disc, and a third drive source for driving the rotating component to move horizontally in a direction perpendicular to the axis of the clamping disc.

[0019] By adopting the above technical solution, the shaft to be processed slides in the feeding groove and can fall from the discharge port onto the transfer component in sequence. The shaft to be processed is transported to the clamping groove by the third drive source, and the shaft to be processed is inserted into the clamping groove by the second drive source.

[0020] Optionally, the machine base is provided with a support base, the rotating component is slidably connected to the support base, the rotating component is provided with a placement groove, the placement groove is used to accommodate the rotating shaft to be processed and passes through one end of the rotating component near the clamping plate, the second drive source includes a movable second output shaft, and the end of the second output shaft is connected to a slider that slides in the placement groove.

[0021] By adopting the above technical solution, the rotating shaft to be processed that falls from the discharge port can enter the placement groove. When the rotating part is moved to the position groove and the clamping groove are opposite, the rotating shaft to be processed can be pushed into the insertion groove by moving the second output shaft.

[0022] Optionally, the machine base is provided with a first support seat that can move horizontally along a direction parallel to the axis of the clamping disc, and a second support seat that can move horizontally on the first support seat along a direction perpendicular to the axis of the clamping disc, and the grinding tool holder is disposed on the second support seat.

[0023] By adopting the above technical solution, when the first and second support platforms move, the grinding tool holder can be moved, which facilitates the installation and disassembly of the shaft to be processed, and makes it easy to move the grinding tool to abut against the outer wall of the shaft to be processed, thereby performing grinding and cutting work.

[0024] Optionally, the feeding track is located on one side of the grinding tool holder, and both the feeding track and the grinding tool holder are detachably connected to the second support seat.

[0025] By adopting the above technical solution, the material feeding track can be moved simultaneously with the movement of the second support seat. This allows the material feeding track to be moved to one side during grinding, reducing interference between the material feeding track and the grinding tool holder. Furthermore, the material feeding track and the grinding tool holder are detachably connected to the second support seat, facilitating replacement and maintenance.

[0026] Optionally, the second support seat has a long groove that is parallel to the length direction of the second support seat. The long groove is a T-shaped groove or a dovetail groove and passes through one end of the second support seat. The feeding track and the grinding tool holder can both move through the long groove and be locked by a locking member after moving along the length direction of the long groove.

[0027] By adopting the above technical solution, a long groove is set to facilitate the adjustment of the position of the feeding track and the grinding tool holder. After the adjustment is completed, the locking parts are used to lock them, thereby improving the applicability of the feeding track and the grinding tool holder.

[0028] Optionally, it also includes a nozzle for spraying coolant, the nozzle spraying in a direction passing through the axis of the clamping disc.

[0029] By adopting the above technical solution, the spray nozzle can be used to cool and reduce the temperature of the rotating shaft to be processed, which is mounted on the clamping plate, by spraying coolant.

[0030] In summary, this application includes at least one of the following beneficial effects:

[0031] 1. During operation, the conveyor rail of the feeding mechanism can sequentially transport the shafts to be processed. The transfer component moves the shafts to be processed from the outlet of the conveyor rail to the clamping plate and fixes them there. At this time, the clamping plate is driven to rotate by the first drive source, and the grinding tool holder moves and grinds and cuts the outer wall of the shaft to be processed by the grinding tool. After completion, the grinding tool holder is removed, and the clamping plate no longer clamps the shaft to be processed, so that the shaft to be processed can be unloaded through the unloading rail, thereby realizing the automatic loading and unloading function and greatly improving work efficiency.

[0032] 2. When the first and second support platforms move, they can drive the grinding tool holder to move, which facilitates the installation and disassembly of the shaft to be processed, and makes it easy to move the grinding tool to abut against the outer wall of the shaft to be processed, so as to carry out grinding and cutting work;

[0033] 3. Long slots are provided to facilitate the adjustment of the material feeding track and grinding tool holder. After the adjustment is completed, the slots are locked with locking components to improve the applicability of the material feeding track and grinding tool holder. Attached Figure Description

Detailed Implementation

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] This application discloses a shaft processing apparatus, referring to... Figure 1 and Figure 2 The rotary shaft processing device includes a machine base 1, on which a first bearing seat 11 is slidably connected, and on which a second bearing seat 12 is slidably connected, with the sliding directions of the first bearing seat 11 and the second bearing seat 12 being perpendicular. The first bearing seat 11 and the second bearing seat 12 are driven to move by one of the following methods: a motor screw structure, a cylinder, a hydraulic cylinder, an electric actuator, etc. The second support seat 12 has two parallel long grooves 121. The length direction of the long grooves 121 is parallel to the sliding direction of the second support seat 12. The second support seat 12 is detachably connected to a grinding tool holder 5 and a feeding track 6. The bottom of the grinding tool holder 5 and the feeding track 6 is fixed with a block that slides in the long groove 121. The long groove 121 is specifically a T-shaped groove or a dovetail groove and passes through one end of the second support seat 12. The corresponding block is also a T-shaped block or a dovetail block, so that the grinding tool holder 5 and the feeding track 6 can be moved and adjusted in position and then locked by a locking member. The locking member can be a bolt that is threaded to the grinding tool holder 5 or the feeding track 6 to abut against the second support seat 12, thereby facilitating the adjustment of the position of the grinding tool holder 5 and the feeding track 6.

[0041] Reference Figure 1 and Figure 2 A clamping plate 2 is provided on one side of the machine base 1. The clamping plate 2 is rotatably connected to the machine base 1 and is driven to rotate by a first drive source, which can be a motor (not shown in the figure). The output shaft and the clamping plate 2 are coaxially and fixedly connected. Four fan-shaped clamping plates 21 are slidably connected to one side of the clamping plate 2. The four clamping plates 21 form an approximately circular shape, and a clamping groove 22 for clamping the rotating shaft to be processed is formed at the center of the circle. The four clamping plates 21 can move towards the center. The specific operation method can be driven by a single cylinder or by a pneumatic four-jaw chuck. These are conventional methods and will not be described in detail.

[0042] When the shaft to be processed is inserted into the clamping slot 22, it is clamped and fixed by the clamping plate 21. At this time, the grinding tool holder 5 can be moved so that the grinding tool 51 set on the grinding tool holder 5 can fit against the outer wall of the shaft to be processed. When the clamping plate 2 is driven to rotate by the first drive source, the grinding tool 51 can grind and cut the outer wall of the shaft to be processed. The machine base 1 is connected to a nozzle 14 with its opening facing downward. The axis of the nozzle 14 is perpendicular to and passes through the axis of the clamping plate 2. The nozzle 14 can be connected to an external coolant circuit, so that coolant is sprayed out through the nozzle 14 to cool and lubricate the shaft being processed.

[0043] Reference Figure 1 and Figure 2 The clamping plate 2 has an installation groove 221 at the clamping groove 22. The inner wall of the installation groove 221 is fixedly connected to a coaxial elastic element 23. The elastic element 23 is a spring, so that when the shaft to be processed is inserted into the clamping groove 22 and abuts against the inner wall of the clamping groove 22 away from the opening, and is clamped and fixed by the clamping plate 21, the elastic element 23 is compressed. When the clamping plate 21 is released, the elastic element 23 can act as an ejector. The shaft can be ejected from the clamping groove 22 and fall into the unloading track 6 by the reset spring force. The unloading track 6 is inclined, and a collection frame 7 is placed on the first support seat 11 or the second support seat 12 to collect the shaft that slides down from the unloading track 6.

[0044] Reference Figure 1 and Figure 3 The shaft processing device also includes a feeding mechanism and a transfer component 4. The feeding mechanism includes a conveyor track 3 fixed to the machine base 1 and arranged at an incline or arc. The conveyor track 3 has a feeding trough 31 along its length. The shafts to be processed can be stored in the feeding trough 31 and slide down sequentially by gravity. Specifically, the feeding trough 31 passes through the bottom of the conveyor track 3 to form a discharge port 32. The width of the feeding trough 31 is adapted to the length of the shaft to be processed, while the depth is slightly greater than the diameter of the shaft to be processed.

[0045] Reference Figure 3 and Figure 4 A support base 13 is fixed on the machine base 1. The support base 13 is located at the bottom of the conveyor track 3, and a guide block 131 is fixed on the top of the support base 13. The transfer component 4 is long and horizontal in length and perpendicular to the axis of the clamping plate 2. The bottom of the transfer component 4 has a moving groove 41 for the guide block 131 to move, thereby providing support and sliding guidance for the transfer component 4 through the support base 13. The transfer component 4 has a placement groove 44 for the shaft to be processed to fall from the discharge port 32. The length direction of the placement groove 44 is perpendicular to the length direction of the transfer component 4, and both ends penetrate through the side wall of the transfer component 4. A slider 421 is slidably connected in the placement groove 44. When the transfer component 4 moves to the point where the placement groove 44 and the clamping groove 22 are opposite, the slider 421 can push the shaft to be processed into the clamping groove 22 for fixing.

[0046] Specifically, a third drive source 43 is installed on the machine base 1. The third drive source 43 is a cylinder, hydraulic cylinder, or electric actuator, and its length direction is parallel to the length direction of the rotating part 4. The output end is fixed to the end of the rotating part 4. When the third drive source 43 works, it can drive the rotating part 4 to move. Since the rotating part 4 is long and narrow, when the discharge port 32 is not aligned with the placement groove 44, the rotating shaft to be processed from the discharge port 32 is blocked by the top surface of the rotating part 4, thus making it difficult to detach from the loading groove 31.

[0047] A second drive source 42 is fixed on the material transfer component 4. The second drive source 42 is one of a cylinder, a hydraulic rod, and an electric push rod. The second drive source 42 includes a second output shaft that can move in a direction parallel to the axis of the clamping disk 2. The end of the second output shaft is fixed to the slider 421 and can be used to drive the slider 421 to move back and forth.

[0048] The implementation principle of the shaft processing device in this application embodiment is as follows: In use, the shaft to be processed can be stored in the loading groove 31 and fed sequentially through the unloading port 32; when the shaft to be processed enters the placement groove 44, the shaft to be processed is driven by the third driving source 43 to face the clamping groove 22, and the slider 421 is driven by the second driving source 42 to move and push the shaft to be processed into the clamping groove 22 and compress the elastic element 23, and drive the clamping plate 21 to clamp and fix the shaft to be processed; finally, the grinding tool holder 5 is moved until the grinding tool 51 abuts against the outer wall of the shaft to be processed, and the clamping plate 2 is driven to rotate and grind and cut with the help of coolant. Finally, after the clamping plate 21 is released, the elastic force of the elastic element 23 can push the shaft out of the clamping groove 22 and transfer it to the collection frame 7 for collection through the unloading track 6.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
