Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 As shown in the figure, the present invention is an automatic positioning and clamping mechanism for machining equipment, including an extrusion mechanism 1 and a hydraulic rod 101. A positioning mechanism 2 is arranged at the bottom of the extrusion mechanism 1. The outer surface of the hydraulic rod 101 is fixedly connected with a top plate 102. The bottom of the hydraulic rod 101 penetrates through the top plate 102 and extends to the outside. The bottom output end of the hydraulic rod 101 is fixedly connected with an adjustment box 103. An activity groove 110 is opened inside the adjustment box 103. An extrusion block 104 is slidably connected to the inner wall of the activity groove 110. Connecting blocks 106 are fixedly connected to both the left and right sides of the extrusion block 104;

[0027] There are two connecting blocks 106 in total. The two connecting blocks 106 are symmetrically arranged with the extrusion block 104 as the center. The parts included in the two connecting blocks 106 are the same. A connecting rod 109 is rotatably connected inside the connecting block 106. The other end of the connecting rod 109 is rotatably connected to a slide block 108. During the downward movement of the adjustment box 103, the extrusion block 104 will first come into contact with the workpiece, and the adjustment box 103 will move downward. While the adjustment box 103 moves downward, the extrusion block 104 will be squeezed into it. While the extrusion block 104 is being squeezed, it drives the connecting block 106 to move upward. While the connecting rod 109 is being pulled, it drives the slide block 108 to approach the extrusion block 104. At the same time, the clamping plate 111 is driven by the slide block 108 to move synchronously. The workpiece is clamped and extruded by the inward movement of the clamping plate 111, and the clamping plate 111 can be adjusted according to the size of the workpiece to improve the applicability of the device.

[0028] The adjustment box 103 is internally provided with a sliding groove 107, and the inner part of the sliding groove 107 is slidably connected to the outer surface of the slider 108. The bottom of the slider 108 penetrates through the adjustment box 103 and is used externally.

[0029] The bottom of the slider 108 is fixedly connected with a clamping plate 111. The top of the clamping plate 111 is slidably connected to the bottom of the adjustment box 103. The bottom of the extrusion block 104 penetrates through the adjustment box 103 and extends to the outside. The top of the extrusion block 104 is fixedly connected with a spring 105, and the top of the spring 105 is fixedly connected to the inner wall of the moving groove 110.

[0030] The positioning mechanism 2 includes a bottom plate 201 fixedly connected to the bottom of the hydraulic rod 101. The inner part of the bottom plate 201 is provided with a sliding groove 204. A motor 202 is fixedly connected to the inner part of the bottom plate 201. The bottom output end of the motor 202 is fixedly connected with a threaded rod 203.

[0031] The outer surface of the threaded rod 203 is threadedly connected with a lifting ring 205. The outer surface of the lifting ring 205 is rotatably connected with a connecting rod 206. There are four connecting rods 206 in total, and the four connecting rods 206 are arranged in a circular array with the threaded rod 203 as the center. When the motor 202 is started, the threaded rod 203 rotates, and the lifting ring 205 moves downward through the rotation of the threaded rod 203. While the lifting ring 205 moves downward, it will pull the connecting rod 206 to move synchronously. While the connecting rod 206 is pulled downward, it will drive the sliding rod 207 to move closer to the center along the sliding groove 204. While the sliding rod 207 moves closer to the center, it will drive the push plate 209 to move closer to the center. Because there are four push plates 209 in total and they move synchronously, the speed and distance when pushing the workpiece are the same, and the workpiece will be pushed to the center to position the workpiece.

[0032] The parts included in the outer surfaces of the four connecting rods 206 are the same. One end of the connecting rod 206 away from the lifting ring 205 is rotatably connected with a sliding rod 207. The outer surface of the sliding rod 207 is slidably connected to the inner wall of the sliding groove 204. The top of the sliding rod 207 penetrates through the bottom plate 201 and extends to the outside.

[0033] The top of the sliding rod 207 is fixedly connected with a fixed ring 208. The outer surface of the fixed ring 208 is rotatably connected with a push plate 209. The inner part of the push plate 209 is provided with a rotating groove 213. The inner wall of the rotating groove 213 is rotatably connected to the outer surface of the fixed ring 208. A rotating rod 210 is rotatably connected to the inner part of the fixed ring 208.

[0034] The front and back of the rotating rod 210 are respectively fixedly connected to the front and back inner walls of the rotating groove 213. A limiting groove 211 is formed inside the fixing ring 208. A limiting plate 212 is slidably connected to the inner wall of the limiting groove 211. The front and back of the limiting plate 212 are respectively fixedly connected to the front and back inner walls of the rotating groove 213. A first spring 214 is fixedly connected inside the limiting plate 212. The bottom of the first spring 214 is fixedly connected to a limiting block 215. The bottom of the limiting block 215 penetrates through the limiting plate 212 and extends to the outside. A first limiting groove 216 is formed in the inner wall of the limiting groove 211. The inner wall of the first limiting groove 216 is adapted to the outer surface of the limiting block 215.

[0035] A specific application of this embodiment is as follows: The worker first places the workpiece on the bottom plate 201, and then rotates the push plate 209. When the push plate 209 rotates, it will drive the limiting plate 212 to slide to the right along the limiting groove 211. When it slides to the rightmost side, the first spring 214 pushes the limiting block 215 downward, so that the limiting block 215 is inserted into the first limiting groove 216 to limit the push plate 209 and keep it in a vertical state without reverse rotation. And when the push plate 209 moves to the vertical state, the limiting plate 212 will move to the leftmost side and cannot move further to the left. Then the motor 202 is started. The rotation of the motor 202 drives the threaded rod 203 to rotate. By the rotation of the threaded rod 203, the lifting ring 205 moves downward. While the lifting ring 205 moves downward, it will pull the connecting rod 206 to move synchronously. While the connecting rod 206 is pulled downward, it will drive the sliding rod 207 to move closer to the center along the sliding groove 204. While the sliding rod 207 moves closer to the center, it drives the push plate 209 to move closer to the center. Since there are four push plates 209 in total and they move synchronously, the speed and distance when pushing the workpiece are the same, and the workpiece will be pushed to the center for positioning. After positioning, the hydraulic rod 101 is started. The start of the hydraulic rod 101 pushes the adjustment box 103 downward. During the downward movement of the adjustment box 103, the extrusion block 104 will first contact the workpiece, and the adjustment box 103 will move downward. While the adjustment box 103 moves downward, the extrusion block 104 will be extruded into it and compress the spring 105. While the extrusion block 104 is being extruded, it drives the connecting block 106 to move upward, and at the same time pulls the connecting rod 109. While the connecting rod 109 is being pulled, it drives the slider 108 to move closer to the extrusion block 104, and at the same time drives the clamping plate 111 to move synchronously through the slider 108. The workpiece is clamped and extruded by the inward movement of the clamping plate 111, and the clamping plate 111 can be adjusted according to the size of the workpiece to improve the applicability of the device.
