DETAILED DESCRIPTION

[0029] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] REFERENCE Figure 1 and Figure 3 An embodiment provided by the utility model: a special gripper for automobile parts production line, including mechanical gripper 1, both sides in mechanical gripper 1 are slidably connected with connecting frame 2, and the outer wall of connecting frame 2 is provided with adjusting assembly and fixed assembly.

[0031] The adjusting assembly comprises a plurality of connecting plates 3 located at the bottom of the connecting frame 2, the top of each connecting plate 3 is fixedly connected with a sliding block 14 which is slidingly connected in the interior of the connecting frame 2, ensuring the flexibility and adjusting ability of the assembly. The top of each connecting frame 2 is fixedly connected with a plurality of fixed shells 15 which provide support and guidance for the connecting columns 11 to move smoothly inside, the interior of each fixed shell 15 is slidingly connected with a connecting column 11 which is designed to effectively transmit force and adjust position, the interior of each connecting column 11 is fixedly connected with a connecting shaft 10 which is used to realize the rotation and linkage between components, the outer wall of each connecting shaft 10 is rotatably connected with a connecting block 9, the rotation of the connecting block 9 helps to realize the adjustment and control of the overall equipment, one end of each connecting column 11 is fixedly connected with a clamping block 13 which is clamped with the interior of the sliding block 14, ensuring the stability of the assembly during work, the connecting block 9 is attached between the fixed shell 15, enhancing the firmness of the connection. The clamping block 13 is slidingly connected in the interior of the connecting frame 2, ensuring flexible movement during adjustment, the outer wall of each connecting column 11 is provided with a spring 12, one end of the spring 12 is fixedly connected to the inner wall of the fixed shell 15, providing necessary elastic support, the other end of the spring 12 is fixedly connected to the outer wall of the clamping block 13, providing a rebound force for the movement of the clamping block 13, further enhancing the function and reliability of the adjusting assembly.

[0032] Specifically, during the adjustment of the equipment, after rotating the connecting block 9, the clamping block 13 at the bottom of the connecting column 11 is effectively pushed out of the interior of the sliding block 14 through the connecting shaft 10, this process causes the spring 12 to compress, and then the connecting plates 3 on both sides move in the opposite direction, at this time, the sliding block 14 smoothly slides in the interior of the connecting frame 2, realizing accurate control of the positional relationship between the two fixed plates 4, thereby effectively adjusting the clamping range of the equipment, then, rotate the connecting block 9 again to make it return to the initial position, push the clamping block 13 to re-enter the interior of the sliding block 14, in this process, the rebound force generated by the spring 12 helps to enhance the clamping effect between the clamping block 13 and the sliding block 14, ensuring the position stability of the two fixed plates 4, not only improving the applicability of the equipment, but also improving the efficiency and reliability of the adjustment process, ensuring that the equipment can perform its best performance in different application scenarios.

[0033] Reference Figure 1 and Figure 2The fixing assembly includes a plurality of rubber discs 7 located on the outer wall of the connecting frame 2, which is responsible for direct contact with the automobile parts to achieve the functions of clamping and fixing. Each connecting plate 3 is fixedly connected with a fixing plate 4 at the bottom, which provides structural support so that the entire fixing assembly can work more stably. Each fixing plate 4 is fixedly connected with a fixing block 5 on one side, which is used to accommodate and guide the movement of the transmission column 6 to ensure that the transmission column 6 can move smoothly. Each fixing block 5 is slidably connected with a plurality of transmission columns 6 inside, which can move freely inside the fixing block 5 to effectively transmit force and adjust the clamping state. Each transmission column 6 is fixedly connected to the outer wall of the rubber disc 7 at one end, so that the rubber disc 7 can generate the necessary extrusion force during clamping to enhance the fixing effect on the automobile parts and ensure its safety and stability during operation. The rubber disc 7 is used to clamp and fix the automobile parts, and its high friction characteristics ensure the stability and firmness during clamping. Each fixing block 5 is provided with a plurality of springs 8 inside, one end of which is fixedly connected to one end of the transmission column 6 to provide the necessary elastic support to generate appropriate extrusion force during clamping. The other end of the spring 8 is fixedly connected to the inside of the fixing block 5 to ensure the stability and reliability of the spring, thereby effectively improving the functionality of the entire fixing assembly.

[0034] Specifically, during the clamping process of the device on the parts, first, the mechanical gripper 1 drives the rubber discs 7 on both sides to move towards the surface of the automobile parts. In this way, the rubber disc 7 comes into contact with the surface of the automobile parts, and the transmission column 6 at one end of the rubber disc 7 is pushed to slide inside the fixing block 5 by the profiled surface of the automobile parts. This movement makes the rubber disc 7 tightly fit the profiled surface of the automobile parts, thereby significantly increasing the contact area between the device and the outer wall of the automobile parts. During the movement of the transmission column 6, it will compress the spring 8, which not only increases the stability of the system, but also uses the rebound force of the spring 8 to apply extrusion to the rubber disc 7 at one end of the transmission column 6 towards the surface of the automobile parts. At the same time, the high friction characteristics of the rubber disc 7 further enhance the fixing effect of the device on the automobile parts, ensuring that the parts will not shift during clamping, effectively improving the stability and safety of clamping, so that the device can be more reliable and efficient when handling automobile parts.

[0035] Working principle: in the device adjustment process, the rotating connecting block 9, through the connecting shaft 10 push connecting column 11 bottom card block 13 from the inside of the slider 14, and make spring two 12 compression, next two side connecting plate 3 reverse movement, and make the slider 14 in connecting frame 2 inside sliding, reach control two side fixed plate 4 position relationship, adjust the clamping range of the device effect, next again rotating connecting block 9, make connecting block 9 reset, so as to push card block 13 re card in the inside of the slider 14, and make use of spring two 12 rebound force enhance the clamping effect between card block 13 and slider 14, reach to two side fixed plate 4 position fixed, enhance the applicability of the device;

[0036] In the device to parts clamping process, using mechanical gripper 1 drive both sides of the rubber disc 7 to move to the surface of the automobile parts, using the automobile parts surface profile push transmission column 6 in the fixed block 5 inside sliding, make rubber disc 7 and automobile parts outer wall profile fit, enhance the equipment and automobile parts outer wall fit area, transmission column 6 in the moving process will compress spring one 8, make use of spring one 8 rebound force push transmission column 6 end rubber disc 7 on the surface of the automobile parts extrusion, and make use of the high friction characteristics of rubber disc 7, enhance the equipment to automobile parts fixed action.
