[0023] Two displacement sensors (4) are arranged at the bottom of the sensor bracket (3) and are used to measure the displacement of the upper end surface of the polished product. When the polished product has an irregularly shaped batch seam, it will affect the clamping of the end surface of the polished product and the gripper, causing the upper end surface of the polished product to be displaced. In addition, the displacement sensor (4) is used to detect whether the gripper is clamped to the polished product, so as to ensure the effective and safe operation of the polishing equipment.
[0024] The clamping device (5) is hydraulically-type and fixedly connected to the inside of the control device (2). A plurality of clamping claws are arranged at the bottom of the clamping device (5). The clamping claws are used to clamp the top shaft (7) of the clamping claw. The clamping claw (8) is connected below the top shaft (7) of the clamping claw, so that the clamping claw (8) is fixed by hydraulic means. When the clamping claw (8) needs to be replaced, the clamping claw is released by the control device (2), and the top shaft (7) and the clamping claw (8) fall off, so that the hydraulic clamping device (5) can realize the rapid replacement of the clamping claw.
[0025] A connecting terminal (6) is also connected above the top shaft (7) of the claw, a through hole is provided at the center of the top shaft (7) of the claw, and the connecting terminal (6) passes through the through hole and is connected to the claw (8) for controlling the opening and closing of the claw (8);
[0026] The top end of the clamping claw (8) is connected to the top end shaft (7) of the clamping claw. After the top end shaft (7) of the clamping claw is locked by the clamping device (5), the clamping claw (8) can clamp the product to be polished under the control of the connecting terminal (6).
[0027] The quick-change machine gripper for automatic grinding has the following action characteristics:
[0028] The machine gripper is set according to the type and variety of the product to be polished. The tops of different types of claws (8) are connected to the claw top shaft (7). When it is necessary to replace different types of polished products, it is necessary to replace the claw top shaft (7) and the claw (8). When the control device (2) sends a gripper release signal, the clamping device (5) will be loosened. After replacing another type of claw top shaft (7) and claw (8), when the control device (2) sends a gripper clamping signal, the claw top shaft (7) at the top of the claw (8) is locked. At this point, the hydraulic clamping device is completed to quickly replace the claw (8);
[0029] When the control device (2) sends a gripper opening signal through the connection terminal (6), the product to be polished is ready to be clamped on the clamping claw (8); when the control device (2) sends a gripper closing signal through the connection terminal (6), the clamping claw (8) clamps the product to be polished to a specified position, thereby realizing the opening and closing control of the clamping claw (8);
[0030] When the displacement sensor (4) detects that the product being polished has an irregularly shaped seam, it will affect the clamping of the end face of the product being polished and the clamping claw (8), and the product being polished needs to be further manually processed before clamping.
[0031] The utility model provides a quick-change machine gripper for automatic grinding. When automatically grinding multiple varieties of products, the machine gripper is set according to the different types and varieties of products, so that the clamping claw (8) can be quickly replaced, the replacement efficiency between working parts can be improved, and the use range of the grinding equipment can be expanded. The displacement sensor (4) can measure the displacement of the product being ground and can detect whether the machine gripper is clamped to the product being ground.
[0032] The utility model has the advantages of realizing rapid replacement of machine grippers during automatic grinding of multiple varieties of products and has the characteristic of high flexibility.
[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
