[0025] The use process of the embodiment is as follows: first, according to different flat plate components, the extrusion distance of the pressing part is adjusted, when adjusting, the telescopic end of the telescopic mechanism 1 moves upward, driving the two driving rod one 21s on both sides to move upward synchronously, under the action of the intermediate hole 24 and the hinged rod one 25, the other end of the driving rod one 21 drives the driving rod two 22 to rotate outward of the work platform 200, so that the extrusion part 23 moves away from the surface of the work platform 200, at this time, the components can be moved to the work platform 200 by using the mechanical arm or the transmission channel, the extrusion distance of the adjusting screw one 231 is changed by rotating the locking nut one 233, that is, the acting range of the pressing head 232 can be changed to adapt to components of different sizes, the pressing strength can be changed by changing the extrusion height of the telescopic end, after the above two conditions are determined, the telescopic end is lowered, driving the pressing head 232 to reset, whether the two distances are appropriate is observed, the above process is repeated to achieve the required pressure and distance.
[0026] After the adjustment is completed, the pressing mechanism 2 can realize the stable fixing and quick releasing process of the components by the above steps, that is, the telescopic mechanism 1 drives the pressing part to press or release the components, and the clamping effect of the plate components is realized by cooperating with the whole process.
[0027] Another embodiment of the application is that two sets of abutting mechanisms 3 are symmetrically arranged on the other two sides of the working platform 200, the abutting mechanism 3 comprises a driving rod three 31 and a driving rod four 32, one end of the driving rod three 31 is connected with a contact part 33, the other end is fixedly connected with the driving rod four 32 at an angle and is hinged to the support frame 100 through a hinge rod two 34, the other end of the driving rod four 32 is connected with an abutting part 35, and the driving rod three 31 and the working platform 200 are connected through a compression spring 36.
[0028] The contact part 33 comprises a threaded hole formed on the driving rod three 31, an adjusting screw two 331 matched with the threaded hole is arranged in the threaded hole, one end of the adjusting screw two 331 is fixedly connected with a contact head 332, and the other end is sleeved with a locking nut two 333 matched with the adjusting screw two 331, the abutting part 35 comprises a threaded hole formed on the driving rod four 32, an adjusting screw three 351 matched with the threaded hole is arranged in the threaded hole, one end of the adjusting screw three 351 is fixedly connected with an abutting head 352, and the other end is sleeved with a locking nut three 353 matched with the adjusting screw three 351, and the telescopic end of the telescopic mechanism 1 can contact or move away from the contact head 332 through up-down movement, so that the up-down movement of the contact head 332 drives the abutting head 352 to contact or move away from the side wall of the component on the working platform 200.
[0029] On the basis of the above embodiment, the telescopic end of the telescopic mechanism 1 moves upward, when it moves to a certain position, it gradually contacts the contact head 332 and pushes the contact head 332 upward to drive the driving rod three 31 to rotate around the hinge shaft two and press the compression spring 36, the driving rod three 31 synchronously drives the driving rod four 32 to rotate to make the abutting head 352 move away from the side wall of the component, and vice versa, the telescopic end descends, does not push the compression spring 36 through the contact head 332, the compression spring 36 releases the elastic force to drive the driving rod four 32 to reset, that is, the abutting head 352 abuts against the component on the working platform 200 again, the extension distance of the telescopic mechanism 1 and the extension length of the pressing head 232 in the early debugging stage are also matched, and then the size of the component is determined to realize the synchronous movement of the telescopic mechanism 1, the pressing mechanism 2 and the abutting mechanism 3, and the component is fixed with appropriate force, the debugging process of the contact part 33 and the abutting part 35 is the same as that of the pressing part, which is simple, fast and stable.
[0030] Thus, the pressing parts on both sides press and fix the components on the workbench 200, exert a vertical force on them, and then the abutting parts 35 on the other two sides abut and fix the components on both sides, exert a horizontal force on them, so as to stably fix the components on the workbench 200, and ensure the effect of the clamp. By adjusting the extension size of the pressing head 232, the extension height of the telescopic mechanism 1, and the extension size of the contact head 332 and the abutting head 352, the entire clamp can adapt to components of various sizes and provide different pressing and abutting forces according to needs when working, so that the components are not damaged due to improper force, and different specifications of the clamp do not need to be replaced. Moreover, the telescopic action of one telescopic mechanism 1 can simultaneously realize stable forces at four positions to stably fix the components on the workbench 200, and the action process is accurate and simple, and the working efficiency is high.

Correspondingly, the telescopic mechanism 1 adopts a telescopic cylinder, and the number of the cylinder telescopic rods thereof is multiple, so as to smoothly drive the force plate 11 to move up and down, and the area of the force plate 11 is large, which can facilitate the connection of the driving rod one 21 and the pushing of the contact head 332, so that the entire action process is more stable. In actual use, the positions of the driving rod one 21 and the contact head 332 can be adjusted on the force plate 11 with a larger area, so as to meet the use requirements of components of larger sizes.
[0032] Among them, the pressing head 232, the contact head 332 and the abutting head 352 are all made of soft silica gel material, which is chemically stable and can withstand high temperature, for example, the environment generating heat when welding components, and also has good elasticity and toughness, and is not easy to deform, preventing damage to fragile components.
[0033] As shown in Figure 1 and Figure 4 , the driving rod two 22 is fixed with a connecting block 220 at one end of the extrusion part 23, and the threaded hole is arranged on the connecting block 220. Since the width of the driving rod two 22 is not too large, it avoids blocking the operation space of the components, and in order to ensure the stable connection of the extrusion part 23, the connecting block 220 for connection is specially arranged at the end of the driving rod two 22 to ensure the connection strength. Correspondingly, the end of the driving rod four 32 can also adopt this operation.
[0034] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
