[0022] In the above structure, by setting the main body 1, motor 2, slide groove 3, slide seat 4, impact rod 5, screw rod 6, inner groove 7, connecting seat 8, and connecting rod 9 structure, the buffer structure can be used in the process of use. The operator can drive the screw rod 6 to rotate through the output shaft of the motor 2, so as to adjust the position of the slide seat 4 on the main body 1, so that the user can use the structure to provide buffering for the lathe tailstock in different positions, thereby improving the flexibility and scope of use of the buffer structure.
[0023] In a preferred embodiment: the outer wall of the limit strip 14 is slidably connected to the inner wall of the strip groove 13, the outer wall of the round rod 19 is fixedly equipped with a limit ring, the inner wall of the movable hole 18 is provided with a circular hole, the outer wall of the limit ring is slidably connected to the inner wall of the movable hole 18, and the inner wall of the circular hole is slidably connected to the outer wall of the round rod 19.
[0024] In the above structure, the strip groove 13, the limit strip 14 and the limit ring structure are set, so that during the operation of the buffer structure, the strip groove 13 and the limit strip 14 are used to limit the connecting tube 15, so as to ensure that the connecting tube 15 can only move along the outer wall of the round rod 19 after being impacted, so that the buffer spring 17 is compressed, and the elasticity of the buffer spring 17 is used to reset the connecting tube 15 after the impact force disappears, thereby ensuring that the subsequent use of the buffer structure will not be affected, thereby improving the stability of the buffer structure.
[0025] In a preferred embodiment, a sliding hole is formed on the outer wall of the striking rod 5 , and the inner wall of the sliding hole is slidably connected to the outer wall of the cross bar 11 . There are two cross bars 11 , and both cross bars 11 are symmetrically distributed along the inner wall of the mounting groove 10 .
[0026] In the above structure, through the sliding hole and cross bar 11 structure, when the impact rod 5 is impacted, the impact rod 5 is used to compress the buffer spring 12, thereby achieving a primary buffering effect, and the connecting tube 15 cooperates with the compression of the buffer spring 2 17 to achieve a secondary buffering effect, thereby improving the buffering effect provided by the buffer structure on the tailstock of the lathe.
[0027] In a preferred embodiment, the outer wall of the connecting seat 8 is slidably connected to the inner wall of the inner groove 7 , a through hole is formed on the inner wall of the inner groove 7 , and the inner wall of the through hole is slidably connected to the outer wall of the connecting rod 9 .
[0028] In the above structure, through the set through hole, inner groove 7, and connecting seat 8 structure, when the motor 2 is working, the rotation of the screw rod 6 will cause the connecting seat 8 to slide along the inner wall of the inner groove 7, so that the slide 4 moves under the pushing action of the connecting rod 9, and the effect of automatically adjusting the position of the slide 4 is achieved, thereby improving the automation of the buffer structure and also being able to improve the scope of use of the buffer structure.
[0029] In a preferred embodiment, the outer wall of the buffer spring 12 abuts against the outer wall of the struck rod 5 , and the outer wall of the buffer spring 2 17 abuts against the outer wall of the connecting tube 15 .
[0030] In the above structure, through the set impact rod 5, buffer spring 12, connecting tube 15, buffer spring 2 17 structure, when the tailstock of the lathe impacts the impact rod 5, the impact rod 5 compresses the buffer spring 12 to achieve a primary buffering effect on the impact force, and after the impact rod 5 squeezes the buffer spring 12, the buffer spring 2 17 will be compressed through the connecting tube 15 to perform a secondary buffering operation, thereby ensuring the buffer structure's offsetting effect on the impact force, thereby improving the buffering performance of the buffer structure.
[0031] In a preferred embodiment, one end of the connecting rod 9 away from the connecting seat 8 is fixedly assembled with the outer wall of the sliding seat 4, and the connecting rod 9 is made of galvanized iron metal.
[0032] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can ensure that the connecting seat 8 will not break when the connecting rod 9 pushes the tube slide seat 4 to slide during movement. At the same time, the galvanized iron metal also has the characteristic of low cost, which can effectively reduce the production cost of the buffer structure.
[0033] Working principle: When the lathe impacts the impact rod 5 during operation, the impact force will cause the impact rod 5 to slide along the outer wall of the cross bar 11 and compress the buffer spring 12, thereby achieving a primary offset of the impact force. At the same time, the impact rod 5 will drive the connecting tube 15 to slide along the outer wall of the round rod 19 when moving, so that the connecting tube 15 compresses the buffer spring 2 17, achieving a secondary offset of the impact force, thereby improving the buffering performance provided by the buffer structure. When the user needs to perform buffering operations on lathe tailstocks of different sizes, the motor 2 can be used to drive the screw 6 to rotate, so that the connecting seat 8 can push or pull the slide 4 to move through the connecting rod 9, so that the impact rod 5 can fit the tailstocks of lathes of different sizes, thereby improving the scope of use and automation of the buffer structure.
