[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The present invention provides a technical solution: an electromechanical automatic clamping device, comprising an L-shaped seat 1, a clamping mechanism 2 is arranged on the inner wall of the L-shaped seat 1, and a stopping mechanism 3 is arranged inside the clamping mechanism 2;

[0025] The clamping mechanism 2 includes a round rod 21, which is connected to the vertical inner wall of the L-shaped seat 1. The round rod 21 is inserted into the inside of the socket 22, and the socket 22 is opened at the upper end of the buffer pad 23. The other end of the round rod 21 is fixedly connected to a fixed plate 24, and the side wall of the fixed plate 24 close to the L-shaped seat 1 is fixedly connected to a cylinder 25. First, the L-shaped seat 1 is moved so that the L-shaped seat 1 and the mobile clamping block 31 are located on both sides of the object to be clamped, and then the cylinder 25 is started, and the retaining ring 310 is pushed by the cylinder 25 to move, and the retaining ring 310 drives the mobile clamping block 31 to move, so that the mobile clamping block 31 and the L-shaped seat 1 are close to each other, and then the buffer pad 23 and the extrusion pad 34 are pushed to clamp the object;

[0026] The stopping mechanism 3 includes a moving clamping block 31, a sliding hole 32 is provided at the upper end of the moving clamping block 31, the sliding hole 32 is slidably sleeved on the surface of the round rod 21, the round rod 21 is inserted into the inside of the through hole 33, the through hole 33 is provided at the upper end of the extrusion pad 34, and the extrusion pad 34 is symmetrically fixedly connected to two springs 35 on the side wall of one side close to the moving clamping block 31, and the other ends of the two springs 35 are respectively clamped in two clamping grooves 36, and the two clamping grooves 36 are respectively provided at both ends of the side wall of one side of the moving clamping block 31, and the extrusion pad 34 is fixedly connected to the trigger rod 3 at the center of the side wall of one side close to the moving clamping block 31 7. The trigger rod 37 passes through the round hole 38 and is inserted into the slot 39. The slot 39 is provided inside the output end of the cylinder 25. A retaining ring 310 is fixedly sleeved on the inner wall of the round hole 38. A stop switch 311 is fixedly connected inside the slot 39. When the object is clamped, the squeezing pad 34 is subjected to reverse pressure, and the pressure pushes the squeezing pad 34 to approach the moving clamp block 31. The squeezing pad 34 pushes the trigger rod 37 to move into the round hole 38, so that the trigger rod 37 is inserted into the slot 39 to squeeze the stop switch 311, so that the cylinder 25 stops running, thereby preventing the moving clamp block 31 from crushing the object due to excessive pressure.

[0027] The lifting mechanism 4 includes a slide groove 41, which is provided on a side wall of the extrusion pad 34 away from the moving clamping block 31. A slider 42 is slidably connected inside the slide groove 41. One end of the slider 42 located inside the slide groove 41 is fixedly connected with a clamping block 43. The clamping block 43 is slidably connected inside a limiting groove 44. The limiting groove 44 is provided inside the slide groove 41. A lifting block 45 is fixedly connected to the other end of the slider 42. A pull rod 46 is fixedly connected to the upper end of the lifting block 45. The upper end of the pull rod 46 is inserted into the inclined groove 47. The inclined groove 47 is provided on the lower surface of the horizontal end of the L-shaped seat 1. The pull rod 46 An inclined hole 48 is provided on the upper side wall, and an inclined plate 49 is inserted into the inclined hole 48. When the extrusion pad 34 moves, it pushes the lifting block 45 to move, and when the lifting block 45 moves, it drives the pull rod 46 to move. When the pull rod 46 moves inside the inclined groove 47, the surface of the inclined plate 49 pushes the inclined hole 48 to move up along the trajectory of the inclined plate 49, thereby causing the pull rod 46 to move up and up, and finally drives the lifting block 45 to move up and up. The upward lifting block 45 drives the contacted object to lift through friction, so that the buffer pad 23 and the extrusion pad 34 clamp the object to prevent the object from falling off from between the buffer pad 23 and the extrusion pad 34.

[0028] The output end of the cylinder 25 contacts the retaining ring 310 accordingly, and then the retaining ring 310 is pushed to move by the cylinder 25 , and the retaining ring 310 drives the movable clamping block 31 to move.

[0029] The pressing pad 34 is located between the buffer pad 23 and the movable clamping block 31 . When the object is clamped, the pressing pad 34 is subjected to reverse pressure, and the pressure pushes the pressing pad 34 to approach the movable clamping block 31 .

[0030] The circular hole 38 is formed on the side wall of the movable clamping block 31 , so that the retaining ring 310 drives the movable clamping block 31 to move.

[0031] The trigger rod 37 contacts the stop switch 311 , and when the trigger rod 37 is pressed, it squeezes the notification switch 311 to control the cylinder 25 to stop.

[0032] The trigger stroke length of the stop switch 311 is longer than the distance between the moving clamp block 31 and the pressing pad 34 , so that the moving distance of the pressing pad 34 is sufficient to push the trigger rod 37 to press the stop switch 311 to operate.

[0033] The two ends of the inclined plate 49 are respectively fixedly connected to the inner walls of the inclined groove 47 on both sides, so that the moving tracks of the inclined plate 49 and the pressing pad 34 are located in the same straight line.

[0034] Specifically, when using the present invention, first move the L-shaped seat 1 so that the L-shaped seat 1 and the mobile clamping block 31 are located on both sides of the object to be clamped, then start the cylinder 25, and push the retaining ring 310 to move through the cylinder 25, and the retaining ring 310 drives the mobile clamping block 31 to move, so that the mobile clamping block 31 and the L-shaped seat 1 are close to each other, and then push the buffer pad 23 and the squeezing pad 34 to clamp the object. When the object is clamped, the squeezing pad 34 is subjected to reverse pressure, and the pressure pushes the squeezing pad 34 to approach the mobile clamping block 31, and the squeezing pad 34 pushes the trigger rod 37 to move into the circular hole 38, so that the trigger rod 37 is inserted into the slot 39 and squeezed to stop. Switch 311 stops the operation of the cylinder 25, thereby preventing the moving clamping block 31 from crushing the object due to excessive pressure. At the same time, when the squeezing pad 34 moves, it pushes the lifting block 45 to move. When the lifting block 45 moves, it drives the pull rod 46 to move. When the pull rod 46 moves inside the inclined groove 47, the surface of the inclined plate 49 pushes the inclined hole 48 to move upward along the trajectory of the inclined plate 49, thereby causing the pull rod 46 to move upward and finally driving the lifting block 45 to move upward. The upward lifting block 45 drives the contacted object to lift through friction, so that the buffer pad 23 and the squeezing pad 34 clamp the object to prevent the object from falling off from between the buffer pad 23 and the squeezing pad 34.
