[0029] In the embodiment of the utility model, the lower plate and the middle plate are rotatably connected via a bearing 26. Four positioning discs 27 are arranged in a circular array on the upper surface of the lower plate with the bearing as the center. Each positioning disc is 90° apart.

The above composition is a rotating mechanism that facilitates the rotation and adjustment of the seat.

[0030] In the embodiment of the utility model, an anti-deflection rod 35 is fixedly connected to the top of the top block. The anti-deflection rod vertically penetrates the pressure plate. The pressure plate is provided with a strip hole 36 for the anti-deflection rod to pass through and get stuck.

[0031] In the embodiment of the utility model, two groups of pressing plates are arranged symmetrically in the transverse direction, and pressing handles 37 are fixedly arranged on the tops of the outer ends of the two groups of pressing plates.

[0032] In the embodiment of the utility model, the upper plate is square, and a clamping assembly 38 is provided at each of its four corners. The clamping assembly includes a longitudinally telescopic clamping cylinder 39, and the telescopic ends of the clamping cylinder are fixedly connected with a clamping plate 40 to move toward each other to clamp the workpiece.

[0033] In the embodiment of the utility model, a handle 41 is fixedly connected to one end of the upper plate away from the slide rod.

[0034] In the embodiment of the utility model, a groove 42 is provided on the lower plate to facilitate clamping on the production line.

[0035] In the embodiment of the utility model, the upper plate is composed of an aluminum plate with holes, a splint and a clamping cylinder. The aluminum plate has the advantages of light weight, good rigidity and strong corrosion resistance. The splint is used to fix the workpiece above. The workpiece is quickly clamped on the assembly fixture plate through the clamping cylinder. Through the cylinder and the air nozzle, fast tightening and loosening are completed, thereby increasing the speed of workpiece replacement and improving production efficiency.

[0036] The working principle of the embodiment of the utility model is as follows: first, the fully adjustable assembly jig tray is placed on the designated production line, and the entire fully adjustable assembly jig tray is clamped on the production line through the groove of the lower plate. Because the fully adjustable assembly jig tray is clamped by the clamping plate and the clamping cylinder of the upper plate, two air nozzle valves are arranged on the middle plate of the jig tray and connected with the clamping cylinder, one is used to contract and clamp the clamping cylinder, and the other is used to push out and loosen the clamping cylinder. After the jig tray is connected to the air pipe, the seat to be assembled can be clamped on it and clamped with the clamping cylinder, and then the seat assembly work can be carried out.

[0037] During the production process, since the assembly is not only the front, but sometimes the sides and back, and sometimes even the bottom, the rotating mechanism and the lifting mechanism of the jig plate can be used; after the seat is clamped, press the lever (pressing plate) to lift the positioning block, push the middle plate, and the middle plate can rotate on the bearing. The lower plate is equipped with four positioning discs, which can support the jig plate to rotate 90°, 180°, and 270°. It can meet the assembly tasks of the side and back of the seat, and the operator can rotate the jig plate; after rotating to the required direction, release the pressing plate, and the positioning block will rebound under the tension of the spring, enter the slot, and be fixed, so that the jig plate will not shake during assembly.

[0038] When it is necessary to assemble the seat at the bottom, a lifting mechanism is required. First, push the operating rod longitudinally to make the push-pull plate slide along the guide rod. When the operating rod is inserted into the L-shaped slot and is in place, rotate the operating rod to make it engage with the L-shaped slot. Then pull out the locking rod to unlock the locking assembly. After unlocking, the upper plate will be lifted up by the action of the gas spring to break away from the support of the nylon block and flip upward around the two rotating wheels. During the process, the rotating wheels will slide in the slide rails and will be limited by the limit assembly to prevent the upper plate from derailing and sliding out. When the bottom assembly is completed, hold the handle of the upper plate and press it down. Due to the lever principle, the upper plate is pressed down, and then the locking assembly is locked to reset the upper plate and continue to complete the next assembly.

[0039] The present invention is not limited to the above-mentioned best implementation mode. Anyone can derive other forms of fully adjustable assembly fixture trays based on the inspiration of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
