For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Please refer to Figure 1 The present embodiment provides an automatic clamping device 100 for clamping a workpiece, which includes a workbench assembly 10, a pressure plate assembly 20 and a pressure block assembly 30. The workbench assembly 10 is used to place the workpiece. The pressure plate assembly 20 is used to cooperate with the workbench assembly 10 to perform preliminary pressing on the workpiece. The pressure block assembly 30 is used to cooperate with the pressure plate assembly 20 to further clamp the workpiece.

[0025] Please refer to Figure 2 Specifically, the workbench assembly 10 includes a workbench 11 and a positioning mechanism 13. The workbench 11 is used to place a workpiece. The positioning mechanism 13 is connected to the workbench 11 in a transmission manner and is used to drive the workbench 11 to move to a preset position. It is understandable that when the workpiece needs to be processed, the workbench 11 is moved to a convenient position in advance by the positioning mechanism 13, so that the worker can perform subsequent processing operations on the workpiece. The preset position can be determined according to the shape and size of the workpiece to be processed.

[0026] In order to facilitate workers to place the workpiece on the workbench 11, in this embodiment, the workbench assembly 10 also includes a table 12. The workbench 11 and the positioning mechanism 13 are both arranged above the table 12. It can be understood that the height of the table 12 determines the height of the workbench 11. Setting the workbench 11 at a certain height facilitates workers to operate the workpiece. In this embodiment, the height of the table 12 is set to be fixed. In other embodiments, the height of the table 12 can be set to be adjustable, that is, the table 12 is set to be a lifting table, which is not limited by the present invention.

[0027] Further, the positioning mechanism 13 includes a guide rail 131, a slider 132 and a first driving member 133. The guide rail 131 is fixedly arranged above the table 12. The slider 132 is slidably connected to the guide rail 131. The slider 132 is also fixedly connected to the workbench 11. When the slider 132 slides on the guide rail 131, the workbench 11 slides along with the slider 132. The first driving member 133 is used to drive the slider 132 to slide along the guide rail 131.

[0028] Please refer to Figure 1 , the x direction in the figure represents the length direction of the workbench 11, and the y direction in the figure represents the width direction of the workbench 11. In this embodiment, the workbench 11 moves along its length direction.

[0029] Please continue to refer to Figure 2,. In order to prevent the slider 132 and the workbench 11 from sliding out of the guide rail 131, a limiter 134 is fixedly provided at the end of the guide rail 131. The limiter 134 is used to limit the sliding range of the slider 132. Specifically, in the present embodiment, the limiter 134 includes a baffle and a block, which are respectively arranged on both sides of the guide rail 131 and fixedly connected to the guide rail 131. It can be understood that when the slider 132 and the workbench 11 move to the two ends of the guide rail 131, the limiter 134 prevents the slider 132 and the workbench 11 from continuing to move outward. The distance between the limiters 134 is the moving range of the slider 132 and the workbench 11.

[0030] Optionally, in other embodiments, the limiter 134 may also be provided with a collision switch or a travel switch (not shown). When the slider 132 and the workbench 11 move to both sides of the guide rail 131, the collision switch or the travel switch detects that the slider 132 and the workbench 11 are close to each other, and transmits a position signal to the controller, and the controller controls the first driving member 133 to stop, thereby limiting the movement range of the slider 132 and the workbench 11. As long as the slider 132 and the workbench 11 can be limited to continue to move to the outside of the guide rail 131, the utility model does not limit the specific structure of the limiter 134.

[0031] Specifically, in the present embodiment, the first driving member 133 includes a screw rod 1332, a nut and a first motor 1331. The screw rod 1332 is fixed to the table 12 through a bearing seat. The extension direction of the screw rod 1332 is consistent with the direction of the guide rail 131. The first motor 1331 is arranged on one side of the screw rod 1332, and is used to drive the screw rod 1332 to rotate. The nut is arranged on the workbench 11 through a bearing. The nut is threadedly matched with the screw rod 1332. It can be understood that the first motor 1331 drives the screw rod 1332 to rotate, thereby driving the nut to move on the screw rod 1332, and then driving the workbench 11 to move along the guide rail 131.

[0032] Optionally, in other embodiments, the first driving member 133 can be set to other linear motion structures, such as a conveyor belt mechanism, a chain mechanism, a linear drive cylinder and other driving structures. As long as the workbench 11 can be moved along the guide rail 131, the utility model does not limit the structure of the first driving member 133.

[0033] In this embodiment, the pressing plate assembly 20 includes a pressing plate 21, a rotating shaft 22 and a rotating mechanism 23. The rotating shaft 22 is arranged on one side of the width direction of the workbench 11. The pressing plate 21 is fixedly connected to the rotating shaft 22. The rotating mechanism 23 is transmission-connected with the rotating shaft 22, and is used to drive the rotating shaft 22 to rotate, so as to drive the pressing plate 21 to approach or move away from the workbench 11. The pressing plate 21 approaches the workbench 11 to press the workpiece on the workbench 11. The pressing plate 21 moves away from the workbench 11 to loosen the workpiece on the workbench 11. Specifically, the rotating mechanism 23 is a motor, which is arranged on one side of the rotating shaft 22, and is used to drive the rotating shaft 22 to rotate. The rotating shaft 22 is fixed on the table 12 through a bearing seat and is arranged on one side of the workbench 11. The extending direction of the rotating shaft 22 is consistent with the extending direction of the guide rail 131. A "U"-shaped connector is arranged on one side of the pressing plate 21 and is fixedly connected to the rotating shaft 22. When the rotating shaft 22 rotates, the pressing plate 21 can rotate synchronously.

[0034] Please refer to Figure 3 It can be understood that when the workpiece needs to be clamped, the workpiece is placed on the workbench 11. The rotating mechanism 23 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the pressing plate 21 to rotate, so that the pressing plate 21 rotates toward the workbench 11 to clamp the workpiece therebetween. Due to the structure of the rotating pressing plate 21, when the shape of the workpiece is different, the pressing plate 21 can be adjusted to any suitable angle according to the actual situation, that is, when the pressing plate 21 is pressed, the pressing plate 21 has a certain angle with the horizontal surface.

[0035] Optionally, in this embodiment, the height of the rotating shaft 22 is fixed, so that the height of the pressure plate 21 in the horizontal plane is fixed. In other embodiments, the height of the rotating shaft 22 can be set to be adjustable, for example, the rotating shaft 22 is set on a conical bearing seat, and a lifting structure can be set below the conical bearing seat to achieve the overall lifting of the pressure plate assembly 20.

[0036] Please refer to Figure 1 , further, when the workbench 11 moves to a preset position, the pressing plate 21 can completely cover the workbench 11. That is, when the workbench 11 moves to any position on the guide rail 131, the pressing plate 21 can cooperate with the workbench 11. Specifically, the length of the pressing plate 21 should be as long as possible to meet the moving range of the workbench 11. When the pressing plate 21 presses the workbench 11, the side of the pressing plate 21 away from the rotating shaft 22 exceeds the edge of the workbench 11.

[0037] Please refer to Figure 4The pressing block assembly 30 includes a pressing block 31 and an adjusting mechanism 32. The pressing block 31 is arranged on a side of the pressing plate 21 away from the workbench 11. Specifically, the pressing block 31, the pressing plate 21 and the workbench 11 are arranged in sequence. It can be understood that the workpiece is placed on the workbench 11. The pressing plate 21 rotates downward and cooperates with the workbench 11 to preliminarily press the workpiece. The pressing block 31 is pressed down and fits with the upper surface of the pressing plate 21, thereby further applying pressure to the pressing plate 21. It can be understood that when the pressing plate 21 is pressed, the pressing plate 21 has a certain angle with the horizontal plane. Therefore, the utility model is provided with an adjusting mechanism 32 for adjusting the angle of the pressing block 31 so that the lower surface of the pressing block 31 is parallel to the upper surface of the pressing plate 21, so as to facilitate the pressing block 31 and the pressing plate 21 to fit. The adjusting mechanism 32 is also used to drive the pressing block 31 to approach or move away from the pressing plate 21. Furthermore, when the pressing block 31 is in contact with the pressing plate 21 , the adjusting mechanism 32 is used to control the pressure of the pressing block 31 on the pressing plate 21 .

[0038] Furthermore, there are multiple pressing block assemblies 30. The pressing block assemblies 30 are arranged at intervals along the length direction of the workbench 11. Specifically, in this embodiment, there are three pressing block assemblies 30, and the distances between the pressing block assemblies 30 are equal, so that the pressure of the pressing block 31 on the pressing plate 21 is uniform. In other embodiments, the number of the pressing block assemblies 30 can be set to two, four or other numbers, which is not limited by the present utility model.

[0039] Specifically, the adjustment mechanism 32 includes a connecting seat 323, a first section arm 321 and a second section arm 322. The connecting seat 323 is arranged on one side of the width direction of the workbench 11. One end of the first section arm 321 is hinged to the connecting seat 323. The other end of the first section arm 321 is hinged to one end of the second section arm 322. The pressing block 31 is arranged at one end of the second section arm 322 away from the first section arm 321. The adjustment mechanism 32 also includes a second driving member 324 and a third driving member 325. The second driving member 324 is used to drive the first section arm 321 and the connecting seat 323 to rotate relative to each other. The third driving member 325 is used to drive the second section arm 322 and the first section arm 321 to rotate relative to each other. It can be understood that in order to improve the space utilization rate of the automatic clamping device, the connecting seat 323 is arranged below the table 12. Thus, the pressing block 31 is arranged above the pressing plate 21 by sequentially arranging the first section arm 321 and the second section arm 322. Furthermore, the first section arm 321 rotates relative to the connection seat 323, and the second section arm 322 further rotates relative to the first section arm 321, thereby achieving the angle adjustment of the pressing block 31 at the end of the second section arm 322. In addition, the connection structure of the first section arm 321 and the second section arm 322 can also achieve the pressing block 31 to approach or move away from the pressing plate 21.

[0040] In order to further achieve fine adjustment of the pressing block 31, the pressing block 31 is rotatably connected to the second arm 322. The adjustment mechanism 32 also includes a fourth driving member 326. The fourth driving member 326 is used to drive the pressing block 31 relative to the second arm 322. Specifically, in the present embodiment, a connecting arm 327 is further provided between the pressing block 31 and the second arm 322. The two ends of the connecting arm 327 are respectively hinged to the pressing block 31 and the second arm 322. The fourth driving member 326 includes two motors, which are respectively arranged at the hinge points of the connecting arm 327 and the pressing block 31 and the second arm 322, and are respectively used to drive the pressing block 31 to rotate relative to the connecting arm 327 and drive the connecting arm 327 to rotate relative to the second arm 322.

[0041] In order to facilitate the height adjustment of the pressing block 31 and facilitate the pressing block 31 to press or release the pressing plate 21, the first arm 321 includes a telescopic component 3211. The telescopic component 3211 is used to adjust the length of the first arm 321. Specifically, in this embodiment, the telescopic component 3211 is a telescopic cylinder.

[0042] Furthermore, the adjustment mechanism 32 also includes a lifting rail 33 and a lifting slider 34. The lifting rail 33 is vertically fixedly arranged on one side of the width direction of the workbench 11. The lifting slider 34 is slidably connected to the lifting rail 33. The lifting slider 34 is fixedly connected to the connecting seat 323. The adjustment mechanism 32 also includes a fifth driving member 35. The fifth driving member 35 is used to drive the lifting slider 34 to slide along the lifting rail 33. Specifically, in the present embodiment, the lifting rail 33 is fixed on the ground and is located below the table 12. When the lifting slider 34 slides on the lifting rail 33, it drives the first section arm 321, the second section arm 322 and the pressing block 31 to move up and down, so as to adjust the height of the pressing block 31. It can be understood that when the workpiece is pressed, the pressing block assembly 30 can be set at a certain height in advance through the lifting rail 33 and the lifting slider 34 to facilitate subsequent work operations.

[0043] Furthermore, the fifth driving member 35 includes a lifting plate 351 and an elevator 352. The elevator 352 is arranged below the lifting plate 351 and is transmission-connected to the lifting plate 351. The elevator 352 is used to drive the lifting plate 351 to rise and fall. The upper surface of the lifting plate 351 abuts against the lifting slider 34. It can be understood that by providing a lifting plate 351, when there are multiple pressing block assemblies 30, the lifting plate 351 can abut against multiple lifting sliders 34, thereby driving the synchronous lifting of the pressing block assemblies 30. Specifically, in the present embodiment, the elevator 352 is a shear-type elevator 352.

The pressure plate 21 approaches the workbench 11 to press the workpiece, and the pressure plate 21 moves away from the workbench 11 to loosen the workpiece. The pressure block assembly 30 comprises a pressure block 31 and an adjusting mechanism 32.
