DETAILED DESCRIPTION

[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0018] Please refer to Figs. 1-3The utility model provides a technical scheme, including installation shell 1, is equipped with first cavity 101 in installation shell 1 inside, is equipped with cylinder 2 in first cavity 101 inside connection, is equipped with connecting plate 3 in installation shell 1 top end connection, is equipped with protective housing 4 in connecting plate 3 top end connection, is equipped with second cavity 5 in protective housing 4 top end, is equipped with clamping arm seat 6 in connecting plate 3 top end inside connection in second cavity 5, is equipped with first through -hole 7 in one side of clamping arm seat 6, is equipped with guide sliding slot 8 in both sides in first through -hole 7 inside, is equipped with protruding part 9 in both sides of clamping arm seat 6 middle end all connection, cylinder 2 top end penetrates connecting plate 3, and is equipped with top rod 10 in connection, is equipped with triangular sliding block 11 in top rod 10 top end rotation, and triangular sliding block 11 is slidably arranged in guide sliding slot 8, is equipped with connecting plate 12 in both sides of triangular sliding block 11 all rotation, is equipped with clamping arm 13 in the rotation of connecting plate 12 between, its effect is that cylinder 2 is as power source, drives triangular sliding block 11 in guide sliding slot 8 sliding through top rod 10, realizes the quick, stable opening and closing action of clamping arm 13, and the design of guide sliding slot 8 ensures the stability and accuracy of triangular sliding block 11 in the moving process, to guarantee the clamping precision of clamping arm 13, clamping arm 13 is rotatably connected with triangular sliding block 11 through connecting plate 12, and this design makes clamping arm 13 can adapt to different shape and size workpieces in the clamping process.

[0019] Second through -hole 14 is equipped with in one side of clamping arm 13 corresponding clamping arm seat 6, its effect is that if clamping arm 13 needs to be replaced due to wear or damage, the design of second through -hole 14 can simplify the replacement process. By disassembling the fixing part matched with the second through -hole, the clamping arm can be easily removed from the clamping arm seat and replaced or repaired, and the expansion and closing of the clamping arm 13 are also facilitated.

[0020] Rubber pad 15 is connected to the opposite side of clamping arm 13, which acts as a buffer layer between clamping arm 13 and the clamped workpiece, effectively reducing the direct pressure and friction on the workpiece surface during clamping, thereby protecting the workpiece from damage.

[0021] One side of the top end of one group of clamping arms 13 is connected to a pressure sensor 16, which can monitor the clamping force of the clamping arm 13 on the workpiece in real time. This is crucial to ensure that the workpiece does not fall off due to insufficient clamping force or is not damaged due to excessive clamping force during clamping. By monitoring the clamping force in real time, the clamping parameters can be adjusted in time to maintain a stable clamping state.

[0022] A clamping opening 17 is provided at the top end of the protective housing 4, which provides a passage for the workpiece to enter and exit the clamping area.

[0023] The installation shell 1 is connected with the installation support 18 on one side, and the installation support 18 is connected with the top end through the stabilizing rod 19, which provides a stable installation foundation for the whole device, ensures that the device will not shake or tilt during operation, and further enhances the structural stability of the device, especially when bearing a large clamping force or external impact, which can maintain the overall stability of the device.

[0024] A plurality of mounting holes are formed in the installation shell 1 and the installation support 18, which can be flexibly installed in different positions or platforms, meeting the diversified needs of automatic production lines, and optimizing the layout of the production line and improving the production efficiency.

[0025] The working principle is that the power source of the clamp is located in the first cavity 101 in the installation shell 1, and when the cylinder receives a signal, it will be elongated or shortened, thereby pushing or pulling the top rod 10 connected thereto. The elongation or shortening of the cylinder 2 is transmitted to the triangular sliding block 11 through the top rod, and the top end of the top rod 10 is rotationally connected with the triangular sliding block 11, which is slidingly arranged in the guide sliding groove 8. When the top rod 10 is pushed, the triangular sliding block 11 will slide in the guide sliding groove 8. Since one end of the clamping arm 13 is rotationally fixed on the protruding portion 9, when the triangular sliding block 11 moves upward, the connecting plates 12 on both sides of the triangular sliding block 11 will move upward, and one end of the connecting plate 12 is rotationally fixed on the other end of the clamping arm 13, so that the clamping arm 13 will make a circular motion around the protruding portion 9, and the clamping arm 13 will move to both sides to open the clamping arm 13. The rubber pad 15 is connected to the opposite side of the clamping arm 13, which is used to increase the friction between the clamping arm and the workpiece, prevent the workpiece from slipping, and protect the workpiece from damage. The pressure sensor 16 is connected to one side of the top end of one set of clamping arms 13, which is used to monitor the clamping force of the clamping arm on the workpiece in real time. The clamping opening 17 is formed in the top end of the protective shell 4, which provides a passage for the workpiece to enter and leave the clamping area.
