Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

The telescopic cylinder 201 is started, and the thrust provided by the telescopic cylinder 201 is 500N. When the output end of the telescopic cylinder 201 pushes the threaded seat 202 forward, the internal thread 204 on the inner wall of the propulsion cylinder 203 matches the threaded seat 202, and under the cooperation of the guide seat 206 and the guide plate 205, the propulsion cylinder 203 cannot rotate. The propulsion cylinder 203 is subjected to the axial force from the threaded seat 202, overcomes the friction force of 50N, and moves forward along the axis. The propulsion cylinder 203 drives the guide plate 205 and the first clamping seat 208 to approach the second clamping seat 209. When the first clamping seat 208 and the second clamping seat 209 contact each other, the parts are clamped and fixed by the grooves on the end faces of both. In this process, due to the cooperation between the limit seat 308 and the limit groove 311 in the initial operation stage, the limiting force on the rotating seat 310 is 400N, and the maximum axial force that can be provided by the contact force between the propulsion cylinder 203 and the threaded seat 202 is 200N. Since the limiting force is greater than the axial force, the propulsion cylinder 203 can be moved forward smoothly to fix the parts.

[0032] Furthermore, a support plate 301 is provided in the control component 3. The support plate 301 is arranged on a side of the top of the workbench 1 away from the mounting table 210. The bottom of the support plate 301 is fixedly connected to the workbench 1 surface. A fixed cylinder 302 is fixedly connected to the side of the support plate 301 close to the telescopic cylinder 201. An assembly seat 303 is sleeved inside the fixed cylinder 302. The outer ring wall of the assembly seat 303 is fixedly connected to the inner wall of the fixed cylinder 302. A plurality of assembly grooves 304 are provided around the assembly seat 303. The plurality of assembly grooves 304 are evenly distributed around the axis of the assembly seat 303. A first connecting cylinder 305 is fixedly connected to the bottom of the inner cavity of the assembly groove 304. A reset spring 306 is built in the first connecting cylinder 305. A second connecting cylinder 307 is sleeved on one end of the reset spring 306 away from the first connecting cylinder 305. One end of the reset spring 306 is fixedly connected to the bottom of the inner cavity of the first connecting cylinder 305, and the other end of the reset spring 306 is fixedly connected to the bottom of the inner cavity of the second connecting cylinder 307. 07 is placed in the assembly groove 304, the end of the second connecting cylinder 307 away from the first connecting cylinder 305 is fixedly connected to the limiting seat 308, the limiting seat 308 is placed in the assembly groove 304, the limiting seat 308 is slidably connected to the groove wall of the assembly groove 304, and the end of the limiting seat 308 away from the assembly seat 303 is provided with a conical surface 309, and a rotating seat 310 is sleeved in the fixed cylinder 302, and the rotating seat 310 is rotatably connected to the inner wall of the fixed cylinder 302 on all sides, and the rotating seat 310 is arranged on the assembly seat On the side of 303 close to the telescopic cylinder 201, the axes of the rotating seat 310, the assembly seat 303 and the telescopic cylinder 201 coincide with each other. A plurality of limit grooves 311 matching the limit seat 308 are provided on the side of the rotating seat 310 close to the assembly seat 303. The limit seat 308 is slidably connected to the groove wall of the limit groove 311. The side of the rotating seat 310 away from the assembly seat 303 is fixedly connected to the tail of the telescopic cylinder 201. After the parts are contacted and fixed, the propulsion tube 203 can no longer move forward. At this time, the propulsion cylinder 203 is subjected to a reaction force of 600N from the parts, and the limiting force of the limit seat 308 on the rotating seat 310 is 400N. Since the limiting force is less than the reaction force, and the guide plate 205 also enters the flip window 207, under the continuous force of the propulsion cylinder 203, the limit seat 308 is forced to enter the assembly groove 304. When the force of the propulsion cylinder 203 is greater than the limiting force, the spring is compressed, and the rotating seat 310 can rotate after losing the restriction of the limit seat 308. Since the rotating seat 310 is fixedly connected to the tail of the telescopic cylinder 201, the telescopic cylinder 201 drives the driving assembly 2 on the top side of the workbench 1 to rotate as a whole, thereby completing the flipping of the parts.

[0033] How it works

[0034] In actual use, the telescopic cylinder 201 is started, and the thrust provided by the telescopic cylinder 201 is 500N. When the output end of the telescopic cylinder 201 pushes the threaded seat 202 forward, the internal thread 204 on the inner wall of the propulsion cylinder 203 matches the threaded seat 202, and the propulsion cylinder 203 cannot rotate under the cooperation of the guide seat 206 and the guide plate 205. The propulsion cylinder 203 receives the axial force from the threaded seat 202, overcomes the friction force of 50N, and moves forward along the axis. The propulsion cylinder 203 drives the guide plate 205 and the first clamping seat 208 to approach the second clamping seat 209. When the first clamping seat 208 and the second clamping seat 209 contact each other, the components are clamped and fixed by the grooves on the end faces of both. In this process, due to the cooperation between the limit seat 308 and the limit groove 311 in the initial operation stage, the limiting force on the rotating seat 310 is 400N, and the maximum axial force that can be provided by the contact force between the propulsion cylinder 203 and the threaded seat 202 is 200N. Since the limiting force is greater than the axial force, the propulsion cylinder 203 can be moved forward smoothly to fix the parts.

[0035] After the parts are contacted and fixed, the propulsion cylinder 203 can no longer move forward. At this time, the propulsion cylinder 203 is subjected to a reaction force of 600N from the parts, and the limiting force of the limit seat 308 on the rotating seat 310 is 400N. Since the limiting force is less than the reaction force, and the guide plate 205 also enters the flip window 207, under the continuous force of the propulsion cylinder 203, the limit seat 308 is forced to enter the assembly groove 304. When the force of the propulsion cylinder 203 is greater than the limiting force, the spring is compressed, and the rotating seat 310 can rotate after losing the restriction of the limit seat 308. Since the rotating seat 310 is fixedly connected to the tail of the telescopic cylinder 201, the telescopic cylinder 201 drives the driving assembly 2 on the top side of the workbench 1 to rotate as a whole, thereby completing the flipping of the parts.

[0036] Only one telescopic cylinder 201 is used to provide power, and the coordinated cooperation of various forces in the above process can operate stably. When the telescopic cylinder 201 thrusts, the connection between the fixing and subsequent flipping actions can be reliably completed, reducing the problems such as the force incoordination that may occur due to multiple power sources, reducing the probability of failure, and improving the reliability of the entire fixture. Starting from starting the telescopic cylinder 201 to provide thrust, no additional complex operations are required, and the fixing and flipping of parts can be achieved in sequence according to the established force relationship. The whole process is automatically carried out by relying on the transmission and conversion of forces, reducing manual intervention and improving production efficiency. In the process of force transmission, various parts are compactly matched, and the propulsion cylinder 203, the guide plate 205 and other parts move in an orderly manner, without unnecessary space waste and force loss. The compact design allows the force to be effectively transmitted between the parts, occupies a small space, and is easy to install and use in the processing workshop. When the first clamping seat 208 and the second clamping seat 209 contact the parts, they are stably clamped under the action of thrust. By adjusting the thrust of the telescopic cylinder 201, it can adapt to the processing of parts of different shapes and sizes. For components with different resistances, stable clamping and flipping can be achieved by relying on force adjustment and the coordination relationship between the forces of the components, and it has strong versatility and adaptability.
