Description

Technical Field

[0001] This application relates to the field of main gear shaft manufacturing, and in particular to a main gear shaft manufacturing equipment and process. Background Technology

[0002] A type of main gear shaft, such as Figure 1 As shown, it includes a head 11 and a tail 12, which are integrally formed. The length of the tail 12 is greater than the length of the head 11. The head 11 and the tail 12 are machined to form a plurality of stepped surfaces 13, which are spaced apart. Both the head 11 and the tail 12 are machined to form end grooves 14 for ejector pins to be inserted. When the ejector pin is inserted into the end groove 14 of the head 11, the ejector pin is flush with the surface of the head 11. When the ejector pin is inserted into the end groove 14 of the tail 12, the ejector pin is flush with the surface of the tail 12.

[0003] In related technologies, when machining the main gear shaft, the tail of the main gear is held by a fixture, and the head is machined by a cutting device. After machining, the head is held by the fixture, and the tail is machined by the cutting device. In the above process, due to the different structures of the tail and the head, the adaptability of the fixture when holding the tail and the head is different, which affects the stability of the tail or head during machining, and thus affects the machining accuracy of the main gear shaft, which needs to be improved. Summary of the Invention

[0004] To improve the machining accuracy of the main gear shaft, this application provides a main gear shaft manufacturing equipment and process.

[0005] Firstly, the main gear shaft manufacturing equipment provided in this application adopts the following technical solution:

[0006] A main gear shaft manufacturing machine includes a bed, on which machining station one and machining station two are provided. The bed is also provided with a clamping device one, a clamping device two, a cutting device one, and a cutting device two. The clamping device one and the cutting device one are located in machining station one, with the clamping device one clamping the head and the cutting device one machining the tail. The clamping device two and the cutting device two are located in machining station two, with the clamping device two clamping the tail and the cutting device two machining the head.

[0007] By adopting the above technical solution, during the processing, clamping device one clamps the head of the workpiece, exposing the tail. Cutting device one moves according to the actually set path to process the tail. After processing, clamping device two clamps the processed tail, exposing the head. Cutting device two moves according to the actually set path to process the head. By clamping the head and tail with clamping device one and clamping device two respectively, it is beneficial to improve the compatibility between clamping device one and the unprocessed head, as well as the compatibility between clamping device two and the processed tail. This improves the positioning stability of the head and tail during the cutting process, thereby improving the processing accuracy.

[0008] Preferably, the first clamping device is provided with a first clamping space, the second clamping device is provided with a second clamping space, and the bed is provided with a positioning post. The first clamping device and the second clamping device are respectively located on opposite sides of the positioning post. The positioning post has a connection port, and the connection port, the first clamping space, and the second clamping space are connected. The first clamping space and the second clamping space are located on the extension path of the connection port.

[0009] By adopting the above technical solution, during the processing, the head is placed in clamping space one, and clamping device one clamps the head. At this time, the head is located on the side of the tail near clamping device two. After the tail is processed, clamping device one releases the head, and another main gear shaft is placed into clamping device one. The main gear shaft with the processed tail is pushed to move towards clamping device two, so that the head enters clamping space two along clamping space one and the connecting port. The head extends out of clamping space two, so that the processed tail is moved into clamping space two. Clamping device two clamps and positions the processed tail, and the head can be processed by cutting device two. This helps to reduce the movement path of the main gear shaft from clamping device one to clamping device two, and helps to improve the processing efficiency of the main gear shaft.

[0010] Preferably, when clamping device one clamps the head of the main gear shaft, clamping workpiece two clamps the tail of another main gear shaft, at which time the adjacent main gear shafts abut against each other.

[0011] By adopting the above technical solution, after the head of the new main gear shaft is placed into the clamping space one, the head of the main gear shaft abuts against the tail of another main gear shaft, so that the tail of the main gear shaft with the processed tail is located in the clamping space two, which makes it easy for the clamping device two to clamp the tail of the main gear shaft.

[0012] Preferably, the bed is provided with a receiving groove, which is located below the second clamping device. A cover plate is rotatably connected to the bed, which is used to cover the receiving groove. The second clamping device is provided with a second driving component, which drives the cover plate to rotate.

[0013] By adopting the above technical solution, during the processing, the cover plate closes the receiving groove, preventing iron filings from entering the receiving groove. After the head of the clamping device 2 is processed, a new main gear shaft is placed into the clamping device 1, causing the main gear shaft processed at the clamping device 2 to fall. When the new main gear shaft is placed into the clamping device 1, the drive assembly 2 drives the cover plate to rotate and open the receiving groove, allowing the main gear shaft falling from the clamping device 2 to fall into the receiving groove, making the receiving of materials timely and convenient.

[0014] Preferably, the bed has a waste chip groove, the cover plate covers the waste chip groove, and the pivot of the cover plate is located between the waste chip groove and the cover plate.

[0015] By adopting the above technical solution, when the cover plate rotates to open the receiving groove, it rotates upward. At this time, the cover plate tilts downward towards the waste chip trough, so that the waste chips above the cover plate move downward into the waste chip trough under the action of gravity, which helps to reduce the amount of waste chips above the cover plate entering the receiving groove.

[0016] Preferably, the clamping device two includes a mounting part one, a rotating part one rotatably connected to the mounting part one, and a plurality of grippers one slidably connected to the rotating part one. The plurality of grippers one are arranged around the outer periphery of the clamping space two. The grippers one slide closer to or away from the clamping space two. The driving assembly two includes a plurality of driving blocks one slidably connected to the mounting part one, a driving member one disposed on the mounting part one, and a driving rod slidably connected to the mounting part one. The driving blocks one are arranged around the outer periphery of the clamping space two. The driving blocks one are located on the side of the grippers one away from the clamping space two. The driving member one drives the driving blocks one to slide closer to or away from the clamping space two. The driving blocks one and the waste chip tray are respectively located on opposite sides of the driving rod. The driving rod is located on the moving path of the driving blocks one. The driving rod abuts against the cover plate.

[0017] By adopting the above technical solution, during the process of driving the first drive block to move closer to the clamping space 2, the first drive block abuts against the first gripper to clamp the tail of the first gripper. After processing, the first drive block moves away from the clamping space 2 and disengages from the first gripper, causing the first gripper to release the tail. During this process, the first drive block abuts against the drive rod and pushes the cover plate to rotate towards the waste chip tray, opening the receiving tray. The second drive assembly simultaneously controls the clamping of the first gripper and the opening and closing of the cover plate. There is no need to set up a separate drive device to drive the clamping of the first gripper and the opening and closing of the cover plate separately, which helps to reduce energy consumption and reflects the concept of energy conservation and environmental protection.

[0018] Preferably, a roller is rotatably connected to the drive block, and the drive block abuts against the gripper via the roller.

[0019] By adopting the above technical solution, the roller abuts against the first gripper, which helps to reduce the friction between the first gripper and the first drive block when the first rotating part drives the first gripper to rotate. This helps to reduce the wear of both the first gripper and the first drive block, and thus helps to improve the service life of the first gripper and the first drive block.

[0020] Preferably, the center of gravity of the cover plate is located on the side of the cover plate's rotation axis closer to the receiving groove.

[0021] By adopting the above technical solution, when the drive block drives the gripper to clamp the tail, the cover plate can quickly close the receiving trough under its own gravity.

[0022] Secondly, regarding the first aspect, the main gear shaft manufacturing process provided by this application includes the following steps: placing the head on a clamping device one, clamping the head on the clamping device one, with the tail outside the clamping device one, and machining the tail on a cutting device one; removing the head from the clamping device one and placing it on a clamping device two that is adapted to the structure of the machined tail, clamping the tail on the clamping device two, with the head outside the clamping device two, and machining the head on the cutting device two.

[0023] By adopting the above technical solution, the head and tail are clamped by clamping device one and clamping device two respectively, which helps to improve the compatibility between clamping device one and the unprocessed head and the compatibility between clamping device two and the processed tail, improve the positioning stability of the head and tail during the cutting process, and thus help to improve the machining accuracy.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By clamping the head and tail with clamping device one and clamping device two respectively, it is beneficial to improve the compatibility between clamping device one and the unprocessed head and the compatibility between clamping device two and the processed tail, improve the positioning stability of the head and tail during the cutting process, and thus improve the machining accuracy.

[0026] 2. When the cover plate rotates to open the receiving trough, it rotates upwards. At this time, the cover plate tilts downwards towards the waste trough, so that the waste on the top of the cover plate moves downwards into the waste trough under the action of gravity, which helps to reduce the amount of waste on the top of the cover plate entering the receiving trough.

[0027] 3. When the drive block drives the gripper to clamp the tail, the cover plate can quickly close the receiving trough under its own gravity. Attached Figure Description

The side of the drive rod 93 away from the drive block 91 abuts against the cover plate 213, and the drive block 91 abuts against the drive rod 93. The drive rod 93 abuts against the cover plate 213, causing the side of the cover plate 213 near the waste chip trough 212 to rotate downward and extend into the waste chip trough 212. This causes the side of the cover plate 213 near the receiving groove 211 to rotate upward and open the receiving groove 211.

[0052] During the machining of the main gear shaft, the head 11 of the main gear shaft to be machined is placed into the clamping space 321, causing the previous main gear shaft to move into the connecting port 241. Then, the finished tail 12 of the previous main gear shaft moves into the clamping space 64. The jaws 33 fit against the head 11 of the main gear shaft to be machined. The driving component 52 drives the driving block 51 to move closer to the clamping space 321. The driving block 51 abuts against the jaws 33 via rollers 53, causing the jaws 33 to move closer to the clamping space 321 to clamp the head 11. The first moving part 92 drives the first gripper 63 to clamp the tail 12 of the main gear shaft located in the second clamping space 64. The third driving part 81 drives the first rotating part 62 and the second rotating part 32 to rotate, thereby driving the main gear shaft at the first clamping space 321 and the second clamping space 64 to rotate. The first tool holder 42, through its cooperation with the first sliding seat 41, processes the corresponding stepped surface 13 and end groove 14 along the cutting path at the tail 12. The second tool holder 72, through its cooperation with the second sliding seat 71, processes the corresponding stepped surface 13 and end groove 14 along the cutting path at the head 11.

[0053] When the gripper 63 on the second processing station releases the processing tail 12, the main gear shaft is processed. The drive unit 92 releases the gripper, and the drive block 51 located below the clamping space 64 moves downward. The drive rod 93 abuts against the cover plate 213, causing the cover plate 213 to rotate and open the receiving groove 211. As the new main gear shaft is placed into the clamping space 321, the processed main gear shaft is pushed into the feeding groove.

[0054] When the first chuck 63 holds the machined tail 12 of the main gear shaft, the first chuck 63 is in contact with the machined tail 12 of the main gear shaft. When the second chuck 33 holds the machined head 11 of the main gear shaft, the second chuck 33 is in contact with the unmachined head 11.

[0055] The implementation principle of a main gear shaft manufacturing equipment according to an embodiment of this application is as follows: the head 11 and tail 12 of the main gear shaft are clamped by clamping device 3 and clamping device 6 respectively, so that clamping device 3 is adapted to the head 11 and clamping device 6 is adapted to the machined tail 12, which makes the main gear shaft less prone to shaking during processing and helps to improve processing accuracy.

[0056] This application also discloses a main gear shaft manufacturing process, including the following steps: placing the head 11 into the clamping space 321, clamping the head 11 with the jaw 33, machining the tail 12 with the jaw 63, moving the head 11 into the clamping space, clamping the tail 12 with the clamping device 6, and machining the head 11 with the tool holder 72.

[0057] The implementation principle of a main gear shaft manufacturing process in this application embodiment is as follows: the head 11 and tail 12 of the main gear shaft are clamped by clamping jaw 1 63 and clamping jaw 2 33 respectively, so that clamping device 1 3 is adapted to the head 11 and clamping device 2 6 is adapted to the machined tail 12, which makes the main gear shaft less prone to shaking during machining and helps to improve machining accuracy.

[0058] 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.
