[0029] Figure 1 This is a schematic diagram of the structure of the self-adjusting clamping device described in this utility model. Figure 2 This is a side sectional view of the self-adjusting clamping device described in this utility model. (See reference) Figure 1-2As shown, the self-adjusting clamping device includes an upper clamping plate 1, a clamping seat 2, a guide block 3, a pneumatic base 4, clamping fingers 5, and a fixing pin 7. The pneumatic base 4 is movably equipped with two clamping fingers 5, which are arranged opposite each other. Both the upper clamping plate 1 and the clamping seat 2 are claw structures, with a connecting end and a claw end at each end. The connecting end of the upper clamping plate 1 and the connecting end of the clamping seat 2 are each connected to one clamping finger 5. The relative position between the claw end of the upper clamping plate 1 and the claw end of the clamping seat 2 matches the relative position between the two clamping fingers 5. The clamping end of the clamping seat 2 is provided with a guide groove 24, and the two ends of the guide groove 24... A pin hole 25 is provided on the side, and a fixing pin 7 is inserted into the pin hole 25. The guide block 3 is set in the guide groove 24 and is hinged by the fixing pin 7. There is a guide gap 6 between the guide block 3 and the bottom of the guide groove 24. The guide block 3 is located between the connecting end of the upper clamping plate 1 and the connecting end of the clamping seat 2. After the pneumatic seat 4 outputs power, the two clamping fingers 5 move towards each other, and drive the clamping ends of the upper clamping plate 1 and the clamping seat 2 to move towards each other. The clamping ends of the upper clamping plate 1 cooperate with the guide block 3 to clamp one or more cables. The guide block 3 adaptively adjusts in the guide gap 6 according to the contact position of the cable, thereby forming a stable clamping effect.
[0030] The connecting end of the upper clamping piece 1 is the first connecting block 11, and the clamping end of the upper clamping piece 1 is the upper clamping claw 13. The first connecting block 11 and the upper clamping claw 13 are fixedly connected. The end face of the upper clamping claw 13 facing the guide block 3 is provided with a rounded guide surface 14, which can avoid damage to the cable caused by hard contact between the upper clamping claw 13 and the cable, and at the same time improve the stability of clamping.
[0031] The connecting end of the clamp 2 is the second connecting block 21, and the gripper end of the clamp 2 is the lower base 23. The lower base 23 is provided with the guide groove 24 facing the upper gripper 13, and the guide groove 24 forms a guide gap 6 with the guide block 3.
[0032] In this embodiment of the utility model, the upper clamping piece 1 further includes a first bending block 12, which connects the upper clamping claw 13 and the first connecting block 11 respectively; the clamping base 2 further includes a second bending block 22, which connects the lower base 23 and the second connecting block 21 respectively; the first bending block 12 and the second bending block 22 cooperate to form a clearance space, which is used to provide clearance space for other components in specific scenarios, so as to be suitable for complex application scenarios and improve space utilization.
[0033] In this embodiment of the utility model, the first bending block 12, the upper clamping claw 13, and the first connecting block 11 included in the upper clamping piece 1 can be integrally formed, and the material of the upper clamping piece 1 can be, for example, a material with good wear resistance and polishing performance, such as S136 steel, SUS304 steel, etc., which has a certain strength to provide support. The surface roughness of the guide surface 14 of the upper clamping claw 13 is Ra0.4-0.8 after rounding corner treatment.
[0034] In this embodiment of the utility model, the second bending block 22, the lower base 23 and the second connecting block 21 included in the clamp 2 can be integrally formed, and the material of the clamp 2 can be, for example, a material with good wear resistance and polishing properties, such as S136 steel, SUS304 steel, etc., which has a certain strength to provide support.
[0035] The upper clamping piece 1 and the clamping base 2 are manufactured by integral molding, which is suitable for mass production and processing and can effectively reduce costs. In other embodiments of this utility model, the various components corresponding to the upper clamping piece 1 and the clamping base 2 can also be manufactured by separate assembly, such as welding, screwing, etc. The various components manufactured separately are assembled together, which can be determined according to the actual application requirements. This utility model does not limit this.
[0036] The guide block 3 includes a guide base 31 and a guide insert 32. The guide insert 32 is mounted on the upper end of the guide base 31. The guide base 31 is inserted into the guide groove 24 and is hinged to the fixing pin 7.
[0037] The guide insert 32 is made of rubber, such as wear-resistant polyurethane or nitrile rubber, which has high wear resistance, a Shore hardness of 50-80°, and a continuous operating temperature of -35-80°. The upper end of the guide insert 32 has a stepped structure, which can provide a flexible support surface for the cable and achieve stable clamping with the upper jaw 13 without damaging the cable.
[0038] The self-adjusting clamping device described in this embodiment of the utility model provides a guide block 3 on the clamping seat 2 and forms a guide gap 6 between the guide block 3 and the clamping seat 2. This allows the guide block 3 and the upper clamping piece 1 to adaptively adjust the clamping position when clamping the cable, thereby achieving stable clamping of one or more cables. The overall structure is simple, reliable, and low in cost.
