Description

Technical Field

[0001] This utility model relates to the field of automotive bushing processing technology, and in particular to a lathe for easy workpiece positioning in automotive bushing production. Background Technology

[0002] When mechanical equipment is running, the shaft rotates at high speed. In order to improve the stability of the shaft, avoid wear caused by friction and heat, and extend the service life of the shaft, a bushing is fixed on the outside of the shaft to protect it. In automobile manufacturing, bushings are also needed to connect the shaft. The bushing usually consists of an outer tube, an inner tube, and a rubber layer. The inner tube and the outer tube are fixedly connected by the rubber layer in the middle. When processing the bushing, the outer tube is usually processed by a lathe, and finally the bushing is assembled as a whole.

[0003] Existing lathes typically use clamping devices to hold and fix outer tubes during use. However, this usually involves multiple cylinders working together to drive the clamping arms to clamp the outer tubes. But when the cylinders malfunction or leak, the clamping becomes unstable, affecting the machining quality. To address this, we propose a lathe for automotive bushing production that facilitates workpiece positioning. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a lathe for easy workpiece positioning in automotive bushing production, which can solve the problems existing in the background art.

One end of the connecting frame is fixedly connected to an output motor. The output end of the output motor is fixedly connected to a bidirectional threaded rod. The outer surface of the bidirectional threaded rod is movably connected to a second movable mounting block through threads.

[0009] In a further technical solution, one end of the second movable mounting block is fixedly connected to one end of the movable connecting block, and the outer surface of the first movable mounting block slides against the inner surface of the connecting sleeve block.

[0010] In a further technical solution, the top of the connecting sleeve block has a flat surface.

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figures 1-4 As shown, a lathe for easy workpiece positioning in automotive bushing production includes a machine body 1. Fixed guide rails 2 are symmetrically arranged on the front surface of the machine body 1. Movable switch doors 3 are symmetrically and movably connected to the inner side of the fixed guide rails 2. Connecting legs 4 are bolted to the inner side of the machine body 1. A connecting mounting base plate 5 is fixedly connected to one end of the connecting legs 4. A fixed clamping mechanism 6 is fixedly connected to the top of the connecting mounting base plate 5.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the bushing can be quickly and stably clamped and fixed by the fixed clamping mechanism 6. At the same time, the fixed clamping mechanism 6 can be quickly connected and fixed to the machine tool body 1 with the cooperation of the connecting mounting base plate 5 and the connecting support leg 4 and bolts, making the operation convenient and quick.

[0027] In another embodiment, such as Figure 2 As shown, an auxiliary reinforcement mechanism 7 is fixedly connected to one end of the top of the clamping component of the fixed clamping mechanism 6.

[0028] The auxiliary reinforcement mechanism 7 can cooperate with the fixed clamping mechanism 6 to reinforce the internal components of the fixed clamping mechanism 6, improve the stability of clamping, and facilitate operation.

[0029] In another embodiment, such as Figure 2 As shown, the fixed clamping mechanism 6 includes a connecting sleeve block 8 and a connecting frame 15. The connecting sleeve block 8 is symmetrically provided with connecting springs 10. The other end of the connecting spring 10 is fixedly connected to a first movable mounting block 9. One end of the first movable mounting block 9 is movably connected to a movable clamping arm 11. The other end of the movable clamping arm 11 is movably connected to a movable connecting block 14. The inner side of the movable clamping arm 11 is movably engaged with a movable clamping block 12. The inner side of the movable clamping block 12 is provided with a clamping groove 13. One end of the connecting frame 15 is fixedly connected to an output motor 16. The output end of the output motor 16 is fixedly connected to a bidirectional threaded rod 17. The outer surface of the bidirectional threaded rod 17 is movably connected to a second movable mounting block 18 via threads.

[0030] The output motor 16 can drive the bidirectional threaded rod 17, enabling the second movable mounting block 18 to move on the outer side of the surface of the bidirectional threaded rod 17, thereby moving the movable connecting block 14, which in turn causes the movable clamping arm 11 and the movable clamping block 12 to deflect. At the same time, when the movable clamping block 12 contacts the bushing, the other end of the movable clamping arm 11 can deflect, causing the first movable mounting block 9 to move inside the connecting sleeve block 8, compressing the connecting spring 10. Meanwhile, the connecting spring 10 can provide a reverse force, thereby stably clamping and fixing the bushing, making operation convenient.

[0031] In another embodiment, such as Figure 2 As shown, one end of the second movable mounting block 18 is fixedly connected to one end of the movable connecting block 14, and the outer surface of the first movable mounting block 9 slides against the inner surface of the connecting sleeve block 8.

[0032] This allows the second movable mounting block 18 to stably drive the movable connecting block 14 to move when it moves, while the first movable mounting block 9 can stably move inside the connecting sleeve block 8, making operation convenient.

[0033] In another embodiment, such as Figure 2 As shown, the top of the connecting sleeve 8 has a flat surface.

[0034] This facilitates a stable connection between the auxiliary reinforcement mechanism 7 and the top plane of the connecting sleeve block 8.

[0035] In another embodiment, such as Figure 3 and Figure 4As shown, the auxiliary reinforcement mechanism 7 includes a connecting mounting arm 19. A movable threaded rod 20 is movably connected to the top end of the connecting mounting arm 19. A connecting base 21 is fixedly connected to the bottom of the movable threaded rod 20. A connecting rotating disk 24 is fixedly connected to the top of the movable threaded rod 20. A movable mounting sleeve 22 is movably sleeved on the outer surface of the connecting base 21. A connecting anti-slip base 23 is fixedly connected to the bottom of the movable mounting sleeve 22.

[0036] The rotating connecting disc 24 facilitates rotation, driving the movable threaded rod 20 and the connecting base 21 to rotate. This allows the movable threaded rod 20 to move downwards inside the connecting mounting arm 19, enabling the connecting base 21 to move the movable mounting sleeve 22 and the connecting anti-slip base 23 downwards. This allows the connecting anti-slip base 23 to press against the top plane of the connecting sleeve 8, thus achieving a connection and fixation. This makes operation convenient.

[0037] In another embodiment, such as Figure 3 As shown, a fixed reinforcing arm 25 is fixedly connected to one side of the connecting mounting arm 19.

[0038] The reinforcing arm 25 is easy to fix and supports the connecting mounting arm 19, making operation convenient.

[0039] The working principle of this utility model is as follows: During use, the bushing is placed at the top center of the connecting mounting base plate 5. Then, the output motor 16 drives the bidirectional threaded rod 17, causing the second movable mounting block 18 to move on the outer side of the surface of the bidirectional threaded rod 17, driving the movable connecting block 14 to move. This causes the movable clamping arm 11 and the movable clamping block 12 to deflect. Simultaneously, when the movable clamping block 12 contacts the bushing, the other end of the movable clamping arm 11 deflects, causing the first movable mounting block 9 to move inside the connecting sleeve block 8, thus connecting the bushing. The connecting spring 10 causes compression, and at the same time, the connecting spring 10 can provide a reverse force, thereby stably clamping and fixing the bushing. Then, the connecting rotating disk 24 is rotated, which drives the movable threaded rod 20 and the connecting base 21 to rotate, so that the movable threaded rod 20 can move downward inside the connecting mounting arm 19, so that the connecting base 21 can move the movable mounting sleeve 22 and the connecting anti-slip base 23 downward, so that the connecting anti-slip base 23 can press against the top plane of the connecting sleeve 8, thereby connecting and fixing. The overall structure is simple and the operation is convenient and quick.

[0040] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
