Technical Field
[0001] The present application relates to the technical field of shaft parts processing, and in particular to a gear shaft flat key press-fitting device. Background Art
[0002] Shaft parts are mainly used to support transmission parts, transmit torque and bear loads. They are usually columnar. When processing shaft parts, they are first fixed on the processing equipment. The processing equipment includes a turning tool. After the turning tool cuts the shaft parts to the specified shape, the shaft parts are then processed more accurately and surface treated. There are keyways on the shaft parts, and keys are provided on the outer wall in the length direction of the shaft parts. The keys are located in the keyways, and shaft parts are usually made of metal materials and have certain magnetism.
[0003] In the current technology, the processing equipment includes a fixture, which clamps the shaft parts in the radial direction so that the relative position of the shaft parts and the fixture is restricted in the radial direction, so as to facilitate the processing of the shaft parts.
[0004] However, during the processing of shaft parts by processing equipment, vibration is easy to occur at the fixture, causing the shaft parts clamped by the fixture to slip in the axial direction, resulting in misalignment of the shaft parts relative to the fixture, thereby affecting the normal progress of the processing process. Utility Model Content
[0005] In order to improve the problem that during the processing of shaft parts by processing equipment, the fixture is prone to vibration, causing the shaft parts clamped by the fixture to slip, resulting in misalignment of the shaft parts relative to the fixture, thereby affecting the normal progress of the processing process, the present application provides a gear shaft flat key pressing device.
[0006] The present application provides a gear shaft flat key press-fitting device that adopts the following technical solution:
[0007] A gear shaft flat key press-fitting device comprises a frame, a limit seat arranged on the frame, a pressure block and a driving member, the limit seat is provided with a limit hole for placing shaft parts, the pressure block is slidably connected to the frame, the driving member is used to drive the pressure block to move toward the shaft part located in the limit hole, the limit seat is slidably connected to the limit block, and the limit block is used to abut against the shaft part located in the limit hole in the axial direction.
[0008] By adopting the above technical scheme, shaft parts are placed in the limiting holes, the driving member is turned on, and the driving member drives the pressure block to move toward the shaft parts until the pressure block abuts against the shaft parts, and at the same time, the shaft parts abut against the inner wall of the limiting hole, thereby limiting the relative displacement of the shaft parts and the limiting seat in the radial direction. When the limiting block abuts against the shaft parts in the axial direction, the relative displacement of the shaft parts and the limiting seat in the axial direction is limited, so that the relative position of the shaft parts and the limiting seat is fixed. When processing shaft parts, the shaft parts are not easily affected by the vibration of the processing equipment and slide with the device, and the shaft parts are not easily misaligned with the processing equipment, which is conducive to the normal progress of the processing process.
[0009] Preferably, a limit spring is provided on the pressure block, one end of the limit spring is connected to the pressure block, and the other end of the limit spring is connected to the limit block, and the limit spring is used to drive the limit block to abut against the shaft part in the limit hole.
[0010] By adopting the above technical solution, the limiting spring drives the limiting block to move toward the shaft part placed in the limiting hole, so that the limiting block can abut against the shaft part in the radial direction more stably, thereby enhancing the limiting effect of the limiting block on the shaft part.
[0011] Preferably, the frame is further provided with a guide rod, the pressing block is connected with a guide plate, the guide plate is slidably connected to the guide rod, and the guide plate slides relative to the guide rod along the length direction of the guide rod.
[0012] By adopting the above technical solution, when the guide plate slides relative to the guide rod along the length direction of the guide rod, the guide plate drives the pressure block to slide relative to the guide rod along the length direction of the guide rod, and the sliding direction of the pressure block is limited, so that each time the pressure block slides, it abuts against the same position of the shaft part, thereby reducing the steps of manually adjusting the relative position of the pressure block and the shaft part, and improving the fixing efficiency of the shaft parts.
[0013] Preferably, the driving member comprises a driving cylinder, the guide plate is detachably connected to an output shaft of the driving cylinder, and the guide plate is detachably connected to the pressing block.
[0014] By adopting the above technical solution, the driving cylinder is connected to the frame, the guide plate is connected to the driving cylinder, and finally the pressure block is connected to the guide plate to complete the installation of the device. When manufacturing the device, the guide plate and the pressure block are first processed separately and then assembled, which makes the manufacturing of the device more convenient and also makes it easier to transfer the device.
[0015] Preferably, the frame is provided with a base, the base is arranged between the frame and the limiting seat, the base is provided with a sliding groove, the limiting seat is provided with a sliding bolt, the sliding bolt is located in the sliding groove, and the sliding bolt slides along the length direction of the sliding groove.
[0016] By adopting the above technical solution, when the shaft parts are placed on the limit seat, when the sliding bolt is slid relative to the base along the length direction of the sliding groove, the limit seat is driven to slide relative to the base, and the relative position of the limit seat and the pressure block is changed, thereby adjusting the relative position of the shaft parts and the pressure block, so that the pressure block can fix the shaft parts more accurately.
[0017] Preferably, a fixing bolt is rotatably provided on the limiting seat, and the fixing bolt is located outside the sliding groove. When the fixing bolt is rotated, the fixing bolt abuts against the base.
[0018] By adopting the above technical solution, when adjusting the relative position of the limit seat and the base, the fixing bolt is rotated to release the abutment against the base, and the limit seat and the base can slide relative to each other; after the relative position of the limit seat and the base is adjusted, the fixing bolt is rotated again to make the fixing bolt abut against the base, and the relative position of the limit seat and the base is fixed. When processing shaft parts, the relative slippage between the base and the limit seat is reduced, thereby reducing the probability of the limit seat causing the shaft parts to be misaligned.
[0019] Preferably, a limiting groove is formed on the limiting seat, the limiting groove is used for accommodating a key on a shaft part, and a groove wall of the limiting groove is used for abutting against the key of the shaft part.
[0020] By adopting the above technical solution, after the shaft parts are placed in the limiting holes, the driving cylinder is started, and the driving cylinder drives the pressure block to apply pressure on the shaft parts toward the limiting seats. The keys of the shaft parts are embedded in the limiting grooves, and the relative positions of the shaft parts and the limiting seats are further fixed in the radial direction of the shaft parts, thereby further reducing the relative displacement of the shaft parts and the limiting seats due to shaking.
[0021] Preferably, the pressing block is made of a strong magnetic material.
[0022] By adopting the above technical solution, when the pressing block abuts against the shaft part, the pressing block produces an adsorption effect on the shaft part, which increases the friction between the pressing block and the shaft part, thereby enhancing the limiting effect of the pressing block on the shaft part.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Place the shaft parts in the limiting hole.

The shaft parts are not easily misaligned with the processing equipment, which is conducive to the normal processing process.
[0025] 2. When the guide plate slides relative to the guide rod along the length direction of the guide rod, the guide plate drives the pressing block to slide relative to the guide rod along the length direction of the guide rod, and the sliding direction of the pressing block is limited, so that the pressing block abuts against the same position of the shaft part every time it slides, reducing the steps of manually adjusting the relative position of the pressing block and the shaft part, and improving the fixing efficiency of the shaft parts;
[0026] 3. When placing shaft parts on the limit seat, the relative position of the shaft parts and the pressing block is adjusted by sliding the sliding bolt relative to the base along the length direction of the sliding groove, so that the pressing block can fix the shaft parts more accurately.

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] The following is combined with Figure 1-4 This application is described in further detail.
[0034] The present application discloses a gear shaft flat key press-fit device. Figure 1 , including a frame 1, a limit seat 2 is fixedly provided on the frame 1, a limit hole 21 is opened on the limit seat 2, the limit hole 21 is used to limit the relative position of the shaft part 5 placed therein and the limit seat 2, a driving member 3 is slidably provided on the frame 1, the driving member 3 includes a driving cylinder 31, a pressure block 32 is threadedly connected on the output shaft 311 of the driving cylinder 31, and the driving cylinder 31 is used to drive the pressure block 32 to move toward the limit seat 2 until the pressure block 32 abuts against the shaft part 5 in the limit hole 21.
[0035] Reference Figure 2 , a plurality of guide rods 35 are fixedly connected to the frame 1 in sequence, and the axial directions of the plurality of guide rods 35 are consistent. A guide plate 33 is fixedly connected to the pressing block 32, and the plurality of guide rods 35 all pass through the guide plate 33. The guide plate 33 is slidably connected with the guide rod 35, and the guide plate 33 slides relative to the guide rod 35 along the length direction of the guide rod 35. The guide plate 33 drives the pressing block 32 to slide relative to the guide rod 35 along the length direction of the guide rod 35. The guide rod 35 limits the sliding direction of the pressing block 32, so that the pressing block 32 abuts against the same position of the shaft part 5 each time it slides, reducing the steps of manually adjusting the relative position of the pressing block 32 and the shaft part 5, and improving the fixing efficiency of the shaft part 5.
[0036] Reference Figure 3 A spring groove 321 is opened on the side of the pressure block 32 facing the limit seat 2, and a limit spring 322 is provided on the pressure block 32, one end of the limit spring 322 is fixedly connected to the bottom of the spring groove 321, and the other end of the limit spring 322 is fixedly connected to the limit block 34, and the end of the limit block 34 close to the limit spring 322 is located in the spring groove 321, and the end of the limit block 34 away from the limit spring 322 is located outside the spring groove 321. The limit spring 322 is used to drive the limit block 34 to slide toward the shaft part 5 located in the limit hole 21, so that the limit block 34 abuts against the shaft part 5.
[0037] Reference Figure 4A limiting groove 323 is opened on the limiting seat 2, and the limiting groove 323 is located on the side of the pressing block 32 close to the limiting seat 2. The limiting groove 323 is used to place the key on the shaft part 5, and the groove wall of the limiting groove 323 is used to abut against the key of the shaft part 5.
[0038] Reference Figure 1 A base 4 is fixedly provided on the frame 1, and the base 4 is arranged between the frame 1 and the limit seat 2. A sliding groove 41 is opened on the side of the base 4 facing the limit seat 2. A sliding bolt 42 is rotatably provided on the limit seat 2. A sliding plate 43 is provided between the bolt head of the sliding bolt 42 and the limit seat 2. A sliding hole 431 is opened on the sliding plate 43. The sliding bolt 42 passes through the sliding hole 431, and the end of the sliding bolt 42 away from its own bolt head is located in the sliding groove 41, so that the bolt head of the sliding bolt 42 abuts against one side of the sliding plate 43, and the base 4 abuts against the other side opposite to the sliding plate 43. The sliding bolt 42 slides relative to the base 4 along the length direction of the sliding groove 41, driving the limit seat 2 and the base 4 to slide relative to each other. When the shaft part 5 is placed on the limit seat 2, when the sliding bolt 42 is slid relative to the base 4 along the length direction of the sliding groove 41, the limit seat 2 is driven to slide relative to the base 4, and the relative position of the limit seat 2 and the pressure block 32 is changed, thereby adjusting the relative position of the shaft part 5 and the pressure block 32, so that the pressure block 32 can fix the shaft part 5 more accurately.
[0039] Reference Figure 1 The sliding plate 43 is provided with a fixing hole 432, which is a threaded hole. The sliding plate 43 is rotatably connected with a fixing bolt 44, which passes through the fixing hole 432. When the fixing bolt 44 is rotated, the fixing bolt 44 abuts against the base 4, so that the friction force generated between the fixing bolt 44 and the base 4 increases, so that the relative position of the fixing bolt 44 and the base 4 is fixed, so that the relative position of the limiting seat 2 and the base 4 is fixed. When adjusting the relative position of the limiting seat 2 and the base 4, the fixing bolt 44 is rotated so that the fixing bolt 44 releases the abutment against the base 4, and the limiting seat 2 and the base 4 can slide relative to each other; after the relative position of the limiting seat 2 and the base 4 is adjusted, the fixing bolt 44 is rotated again so that the fixing bolt 44 abuts against the base 4, and the relative position of the limiting seat 2 and the base 4 is fixed. When the shaft parts 5 are processed, the relative sliding of the base 4 and the limiting seat 2 is reduced, thereby reducing the probability of the limiting seat 2 driving the shaft parts 5 to be misaligned.
[0040] The implementation principle of a gear shaft flat key pressing device in an embodiment of the present application is: place the shaft part 5 in the limiting hole 21, turn on the driving cylinder 31, and make the driving cylinder 31 drive the pressure block 32 to move toward the shaft part 5 until the pressure block 32 abuts against the shaft part 5, and at the same time, make the shaft part 5 abut against the inner wall of the limiting hole 21, so as to limit the relative displacement of the shaft part 5 and the limiting seat 2 in the radial direction. When the limiting block 34 abuts against the shaft part 5 in the axial direction, the relative displacement of the shaft part 5 and the limiting seat 2 in the axial direction is limited, so that the relative position of the shaft part 5 and the limiting seat 2 is fixed. When processing the shaft part 5, the shaft part 5 is not easily affected by the vibration of the processing equipment and slides with the device, and the shaft part 5 is not easily misaligned with the processing equipment, which is conducive to the normal progress of the processing process.
[0041] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
