Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to a flip-type pressure maintaining mechanism. Background Technique

[0002] Currently, in the process of automobile production and processing, multiple components usually need to be assembled with each other, and some components need to be strengthened after being connected. For example, after adopting the glue connection process, the product needs to be pressed and cured.

[0003] In the prior art, adding counterweights is adopted. This method increases the number of counterweights, resulting in a bloated and heavy mechanism, and it is easy to tip over, with poor stability. Or a spring mechanism is used. This method obtains a large pressing pressure through the spring mechanism, but the spring force cannot be accurately determined, and a large error will be formed between multiple pressing jigs, resulting in uneven quality of the pressed products. Secondly, as the number of uses increases, the elastic force will gradually decrease, and it is easy to have a situation of insufficient pressure, resulting in unstable product quality.

[0004] As disclosed in a pressure maintaining mechanism of Chinese Patent CN216153110U, it includes a top plate, a guiding component, a moving plate and a connecting rod group. The moving plate can move along the guiding component, and the connecting rod group is arranged between the top plate and the moving plate. The top plate part can apply pressure to the connecting rod group, and the connecting rod group can convert the applied pressure into a greater thrust to push the moving plate to move away from the top plate to press the product. Through the above-mentioned connecting rod group, the external force applied to the connecting rod group can be amplified, so that the effect of increasing the pressing pressure can be achieved without additionally increasing the external force.

[0005] However, during the use of this device, the carrier will be damaged due to long-term extrusion, and it is not convenient to replace it, thus affecting the automobile processing efficiency.

[0006] Therefore, we urgently need to provide a flip-type pressure maintaining mechanism. Content of the Utility Model

By engaging the clamping rod 204 with the slots, it is convenient to fix the assembly jig 201 on the top of the base 1. The fixing block 202 is fixedly installed on the left side of the top of the base 1 around the assembly jig 201. Limiting holes are provided inside the fixing block 202 and the support block 203, and the clamping rod 204 is slidably connected inside the limiting holes. Through the limiting holes, the clamping rod 204 can only move linearly, which is convenient for the clamping rod 204 to engage with the assembly jig 201. The support block 203 is fixedly installed at the front and rear ends on the left side of the base 1. The clamping rod 204 is movably installed inside the adjacent fixing block 202 and support block 203. The push plate 205 is fixedly installed on the outer sides of the left and right clamping rods 204. The spring 206 is installed between the push plate 205 and the support block 203.
