[0027] Existing clamping devices, when clamping irregularly shaped parts, suffer from problems due to the large clamping area, making it difficult to adjust the clamping force evenly at different locations on the part. For these reasons, this application proposes an improved clamping force adjustment device.

[0028] One specific embodiment of the clamping force adjusting device shown in Figures 1 to 3 includes: a fixed plate 2, a screw 4, a sleeve 7, a pressure column 8, and an elastic element 6.

[0029] As shown in Figures 2 and 3, the fixing plate 2 has a stepped hole. The screw 4 is threadedly connected to the first threaded hole 9 in the stepped hole. The outside of the sleeve 7 is connected to the second hole 10 in the stepped hole, the diameter of the second hole 10 being larger than the diameter of the first threaded hole 9. One end of the pressure column 8 is adapted to make pressure contact with the part to be pressed, and the other end of the pressure column 8 slides inside the sleeve 7; and the other end of the pressure column 8 is adapted to be engaged with the inner side of the clamping platform provided near the end of the sleeve 7. The elastic element 6 is disposed inside the sleeve 7, and the elastic element 6 is located between the screw 4 and the other end of the pressure column 8. The clamping force adjusting device is adapted to compress the elastic element 6 by screwing the screw 4 with a scale, thereby applying a thrust to the pressure column 8 through the elastic element 6, so as to use the pressure column 8 to press the part to be pressed; the scale corresponds to the clamping force of the pressure column 8 on the part to be pressed. Specifically, the scale corresponds to the compression amount of the elastic element 6, and the compression amount of the elastic element 6 corresponds to the clamping force.

[0030] Specifically, the second hole 10 is a second threaded hole; the outer circumferential thread of the sleeve 7 is connected to the second threaded hole.

[0031] Furthermore, as shown in Figure 3, the diameter of the first threaded hole 9 is smaller than the inner diameter of the sleeve 7 where the elastic element 6 is located; a pressure block 5 is provided between the screw 4 and the elastic element 6, and the pressure block 5 is slidably connected inside the sleeve 7.

[0032] Furthermore, as shown in Figure 1, the screw 4 has a hexagonal screw head at the screwing end.

[0033] Specifically, as shown in Figure 3, the elastic element 6 is a spring.

[0034] Furthermore, as shown in Figure 1, the part to be pressed is an irregularly shaped part; the screw 4, sleeve 7, pressure column 8 and elastic element 6 constitute a pressing force adjustment unit 3, and multiple sets of pressing force adjustment units 3 are distributed on the fixed plate 2, and different pressing force adjustment units 3 are suitable for adjusting the pressing force separately.

[0035] Specifically, as shown in Figure 1, the fixing plate 2 is L-shaped; the clamping force adjustment unit 3 is located on the horizontal part of the L-shaped fixing plate 2. As shown in Figure 1, two rows and three columns of clamping force adjustment units 3 are distributed on the horizontal part of each L-shaped fixing plate 2.

[0036] Furthermore, as shown in Figure 1, the two L-shaped fixing plates 2 equipped with the clamping force adjustment unit 3 are arranged with their openings facing each other, and the vertical parts of the two fixing plates 2 are connected to the telescopic member 1. Alternatively, the top ends of the vertical parts of the two L-shaped fixing plates 2 can be connected to the bottom surface of the connecting plate 11, and the top surface of the connecting plate 11 can be connected to the telescopic end of the telescopic member 1.

[0037] Furthermore, the telescopic member 1 is connected to the movable arm.

[0038] Specifically, the telescopic component 1 is a cylinder.

[0039] The working process of the clamping force adjustment device described in this application is briefly described as follows: First, keep the moving arm stationary; second, place the part to be clamped on a horizontal surface, adjust the clamping force of the pressure column 8 to the maximum value, and ensure that the end of the pressure column 8 is in pressure contact with the part to be clamped, i.e., the spring is in the ultimate clamping state; third, adjust the screws 4 at different positions according to the structure of the irregular part to be clamped, and record the scale value corresponding to each screw 4, and check the corresponding clamping force until it meets the clamping force test requirements; fourth, after the clamping force test is completed, store the part to be clamped.
