[0025] refer to Figures 1 to 3 As an object of the present invention, a clamping device is provided, which includes a support assembly 1, a first clamping assembly 2, a second clamping assembly 3 and a transmission assembly 4. The first clamping assembly 2 and the second clamping assembly 3 are arranged on opposite sides of the support assembly 1, and the first clamping assembly 2 and the second clamping assembly 3 are each independently and automatically movable to clamp or release materials. The transmission assembly 4 is fixedly connected to the support assembly 1 and is used to be connected to a driving member (not shown) to drive the support assembly 1 to move. Therefore, since the clamping device provided by the present invention is provided with two clamping assemblies, it can clamp two or more materials at the same time, and the two clamping assemblies can be moved in an automated manner to clamp or release materials, so the degree of automation is high, and by controlling the range of movement, it can adapt to materials of different shapes, so that it has high versatility, and a transmission assembly 4 fixedly connected to the support assembly 1 is also provided, whereby the clamped materials can be conveniently transported to the processing position, which significantly improves the work efficiency.

[0026] Please refer to the following for further reference Figure 1 and Figure 2Specifically, the first clamping assembly 2 includes a pair of first cylinders 21, a pair of first moving blocks 22, and a first clamping block group 23 provided on each first moving block 22. The pair of first cylinders 21 drive the pair of first moving blocks 22 to move toward or away from each other, so that the two first clamping block groups 23 approach or move away from each other to clamp or release the material accordingly. The second clamping assembly 3 includes a pair of second cylinders 31, a pair of second moving blocks 32, and a second clamping block group 33 provided on the two second moving blocks 32. The pair of second cylinders 31 drive the pair of second moving blocks 32 to move toward or away from each other, so that the two second clamping block groups 33 approach or move away from each other to clamp or release the material accordingly. In this way, the two clamping assemblies use cylinders to accurately control the spacing between the moving block pairs, so that the corresponding materials can be clamped reliably and adaptively.

[0027] Please refer to the following for further reference Figure 1 , more specifically, the first cylinder 21 and the second cylinder 31 each include a cylinder body and a piston rod, the cylinder bodies of a pair of first cylinders 21 and a pair of second cylinders 31 are aligned adjacently and the piston rods are aligned oppositely, the first clamping block group 23 includes a first clamping block 231 and a second clamping block 232, and the first clamping blocks 231 and the second clamping blocks 232 of the two first clamping block groups 23 are arranged in pairs, and the second clamping block group 33 includes a third clamping block 331 and a fourth clamping block 332, and the third clamping blocks 331 and the fourth clamping blocks 332 of the two second clamping block groups 33 are arranged in pairs. In this way, each clamping assembly has two pairs of opposing clamping blocks, so that the material can be clamped stably.

[0028] Please refer to the following for further reference Figure 1 Preferably, the first clamping block group 23 and the second clamping block group 33 each further include a plurality of pairs of pillars 233, 333 and support plates 234, 334, one end of the pillars 233, 333 is fixedly connected to the first moving block 22 or the second moving block 32 and the other end is fixedly connected to the support plates 234, 334, and a corresponding clamping block is fixed on the side of each support plate 234, 334 facing away from the first moving block 22 or the second moving block 32. Therefore, the clamping block is supported by the support of the pillars 233, 333 and the support plates 234, 334, so that the clamping block is well supported and can closely apply symmetrical clamping forces to the opposite sides of the material. In addition, by setting the pillars 233, 333 to different heights, the versatility for materials in different states can be further improved.

[0029] Please refer to the following for further reference Figure 1Specifically, the support assembly 1 includes a first support plate 11 and a second support plate 12 which are arranged in parallel and have a spacing therebetween, and a connecting plate 13 connected between the first support plate 11 and the second support plate 12.

Therefore, the overall structure of the support assembly 1 is compact, and the relative position of the first cylinder 21 and the second cylinder 31 is accurately positioned, thereby ensuring that each clamping assembly accurately clamps the clamped position of the material.

[0030] Please refer to the following for further reference Figure 1 Preferably, the clamping device further comprises a mounting seat 5 arranged in the spacing space, an electrical terminal 6 electrically connected to each cylinder is arranged on the mounting seat 5, and a displacement detector 7 for detecting the position of the bracket assembly 1 is arranged on one side plate of the mounting seat 5, and a clamping detector 8 for detecting whether the first clamping assembly 2 and the second clamping assembly 3 clamp the material in place is respectively arranged on the first support plate 11 and the second support plate 12. Therefore, the displacement detector 7 can accurately determine whether the bracket assembly 1 and thus the material are moved in place, thereby ensuring that the material is further processed accurately, and the clamping detector can accurately determine the posture of the material being clamped on the clamping assembly, thereby ensuring that each preset clamping position of the material is clamped.

[0031] Please refer to the following for further reference Figure 1 Preferably, clamping grooves 235 and 335 are provided on each clamping block, so that different clamping grooves 235 and 335 can be set according to different clamping positions of the material, further increasing the reliability of clamping the material. The clamping blocks are made of silicone or rubber, so as to avoid wear on the material. In the initial state, each cylinder is arranged in the horizontal direction, and in the horizontal direction, different clamping block pairs in each clamping assembly are horizontally opposite and have different horizontal spacings. In the vertical direction, the two first clamping block groups 23 and the two second clamping block groups 33 are arranged relative to each other in a mirror-image rotation of 180 degrees. In this way, under the drive of the transmission component, only the first clamping assembly 2 and the second clamping assembly 3 need to be flipped 180 degrees relative to each other, so that the same type of materials can be clamped quickly and sequentially, further improving the work efficiency.

[0032] Please refer to the following for further reference Figure 2 and Figure 3Specifically, the transmission assembly 4 includes a motion connection mechanism 41, a transmission column 42 and a fixing ring 43 such as a flange. The motion connection mechanism 41 includes a connection base and a plug-in column 411, a clamping groove 412 and an identification groove 413 provided on the connection base. The plug-in column 411 is used to be plugged and matched with the driving member so as to transmit the driving force of the driving member. The clamping groove 412 is used to be clamped and fixed with the driving member. The identification groove 413 is used to determine that it is connected to the preset matching driving member. One end of the transmission column 42 is fixed to the connection base and the other end is fixed to the connecting plate 13 through the fixing ring 43. In this way, through the above-mentioned setting of the motion connection mechanism 41, it can be ensured that the transmission assembly 4 can be securely and accurately connected to the driving member such as the manipulator.

[0033] As another object of the utility model, the utility model also provides a processing equipment (not shown), which includes a driving member and any one of the above clamping devices. The processing equipment can obtain the beneficial effects brought by any one of the clamping devices, which will not be repeated here. Therefore, the processing equipment has the advantages of high degree of automation, ability to perform processing such as opening holes on multiple clamped materials sequentially or simultaneously, and high versatility.

[0034] Specifically, the processing equipment includes a robot, and the driving member is a manipulator of the robot. Therefore, the use of the manipulator of the robot to drive the bracket assembly has the advantages of flexible operation and high degree of automation. In addition, in the utility model, the material is a plastic oil tank, and the clamping device is used to clamp the oil tank to the processing position so that the robot's manipulator can be used to replace the cutting device and further open a hole in the oil tank.
