This type of gripper is usually made of durable materials such as steel or synthetic composites to ensure long-term durability and reliability. The anti-slip properties mainly come from the design of the gripper, which may include special surface textures, coatings, or soft pads, which can increase friction with the gripped object to prevent slippage.

A through groove 11 is provided at the lower end of the mounting seat 1. The driving mechanism 2 comprises a motor 21 fixedly mounted in a groove inside the mounting seat 1, and a gear rack mechanism 22 fixedly mounted on the motor 21.

The telescopic mechanism 37 can adopt a telescopic mechanism such as a starting telescopic rod and an electric telescopic rod. The anti-skid column 36 is concentrically aligned with the through hole 33.
[0028] Slide rails are arranged at both ends of the through slot 11, and slide grooves matching the slide rails are arranged at both ends of the clamping block 31. Similarly, slide rails are arranged at both sides of the sliding bin 34, and slide grooves matching the slide rails are arranged at both sides of the moving plate 35.
[0029] The gear rack mechanism 22 includes a driving gear 221 fixedly connected to the main shaft of the motor 21 and a driven rack 222 arranged on the clamping block 31. The driven racks 222 on the clamping blocks 31 at both ends are axially symmetrically distributed, and the driven racks 222 and the driving gear 221 are installed in coordination.
[0030] The upper end of the mounting seat 1 is provided with a fixing member 12. The fixing member 12 is mounted on the flange of the mechanical arm.
[0031] The anti-skid column 36 includes a plurality of fixed columns 361 fixedly connected to the moving plate 35 , and anti-skid contacts 362 disposed on the fixed columns 361 . The anti-skid contacts 362 are made of a flexible silicone material.
[0032] The anti-skid convex pad 32 is made of hard rubber material.
[0033] The diameter of the through hole 33 is slightly larger than the diameter of the anti-skid column 36 .
[0034] Pressure sensing sheets are provided between the clamping surface of the clamping block 31 and the anti-slip convex pad 32 , and between the fixed column 361 and the movable plate 35 .
[0035] Example 2
[0036] The working principle of this utility model:
[0037] The anti-skid mechanical claw designed by the utility model can respectively perform anti-skid grasping on rigid objects and flexible objects.
[0038] The mechanical claw is mounted on the mechanical arm, and the motor, telescopic mechanism and pressure sensor are electrically connected to the control unit. By operating the control unit, the motor 21 of the mechanical claw rotates the driving gear 221, and the driving gear 221 drives the driven racks 222 on both sides to move relative to each other, thereby achieving the clamping or releasing movement between the clamping blocks 31.
[0039] When the mechanical claw is required to clamp a rigid object, the motor 21 rotates, and the clamping block 31 moves inward to clamp the clamping block 31. During the clamping process of the clamping block 31, the pressure sensor between the clamping surface of the clamping block 31 and the anti-skid convex pad 32 can detect the clamping pressure and feed back the pressure value to the control unit. The control unit can control the rotation of the motor so that the clamping block 31 can clamp the rigid object adaptively and safely. The multiple anti-skid convex pads 32 on the clamping block 31 play an anti-skid role on the rigid object. At this time, the telescopic mechanism 37 in the clamping block 31 is in a retracted state, so the moving plate 35 is located at the innermost side of the sliding bin 34, and the multiple anti-skid columns 36 are retracted into the clamping block 31.
[0040] When the mechanical claw is required to clamp the flexible object, the telescopic mechanism 37 is activated to push the movable plate 35 to move. When the telescopic rod reaches the set formation of the telescopic mechanism 37, it stops moving. At this time, the anti-skid column 36 extends out of the clamping surface of the clamping block 31 through the through hole 33 under the movement of the movable plate 35, and the clamping force is provided by the telescopic mechanism 37. After the anti-skid column 36 is extended, the height of the fixed column 361 is slightly greater than the height of the anti-skid convex pad 32. The anti-skid contact 362 of the flexible silicone material can prevent the flexible object from being damaged during the clamping process. When the clamping block 31 clamps the flexible object, a pressure sensor sheet is provided between the fixed column 361 and the movable plate 35, and the control unit can control the rotation of the motor so that the anti-skid column 36 can clamp the flexible object adaptively and safely.
[0041] The utility model integrates clamping mechanisms suitable for rigid and flexible objects, so that the mechanical claw can not only firmly clamp rigid objects but also gently handle flexible objects, thereby significantly improving its versatility and operating efficiency.
