[0002] When clamping, baking, shaping, loading and unloading glass fiber composite materials with a thickness of 1.5-3mm, it is necessary to ensure that the clamp will not be melted during baking and cannot be clamped, and it is also necessary to ensure the movement speed of the clamp during shaping and loading and unloading. If the speed cannot be guaranteed, the material will be pulled out by the clamp, and it is also necessary to ensure that the material will not be clamped through by the clamp after baking. However, the existing clamps are very prone to melting bridge bending during baking, causing the clamp to be skewed or unable to clamp. The skewness will cause the product to be clamped through, which seriously affects the product quality and leads to the production of defective and scrapped products. Therefore, it is urgently needed to design a high-temperature resistant clamp with a micro-unlocking force frame and retractable function to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In a specific embodiment of the present invention, Figure 1-Figure 6 As shown, a high temperature resistant clamp with a micro-unlocking force frame and a telescopic function is specifically disclosed, comprising a frame 1, a plurality of telescopic rods 2, and a plurality of clamping claw assemblies 3 respectively arranged on the four sides of the frame 1, wherein the plurality of telescopic rods 2 are respectively arranged in the four sides of the frame 1, and each of the telescopic rods 2 is connected to a driving mechanism, and the plurality of clamping claw assemblies 3 are used to clamp products in the inner cavity of the frame 1;

[0028] Each clamping jaw assembly 3 includes a connecting block 31, a slide plate 32, a flip linkage assembly 33 and a plurality of clamping jaws 34. The connecting block 31 is sleeved on the corresponding telescopic rod 2 and fixed to the telescopic rod 2. The slide plate 32 is arranged on the frame 1 and the bottom is connected to the connecting block 31. The flip linkage assembly 33 is arranged on the slide plate 32. A plurality of clamping jaws 34 are connected to the flip linkage assembly 33 and are arranged in coordination with the slide plate 32.

[0029] The clamp of the present invention adopts a method of clamping inwards from all sides, and uses the same driving mechanism to keep the telescopic rods 2 on all sides of the frame to be able to be evenly extended and retracted to ensure the moving speed of the clamp, and the clamping claws 34 cooperate with or move away from the slide plate 32 under the flipping of the flip linkage assembly 33 to clamp or release the four sides of the product, maintain the stability of the clamp, and solve the problem that the uneven tension of the clamp is easy to pull and damage the product;

[0030] The flip linkage assembly 33 includes a support frame 331, a lifting plate 332, a flip plate 333 and a fixed frame 334. The support frame 331 is Z-shaped. One end of the support frame 331 is fixedly arranged in the end of the slide plate 32 away from the clamping claw 34, and the other end extends outward. The end of the support frame 331 extending outward is penetrated by a first pin shaft 335. The flip side of the lifting plate 332 is sleeved on the outer side of the pin shaft connecting sleeve 336, and the two are connected by a second pin shaft 337. The pin shaft 337 and the first pin shaft 335 are connected by a pin shaft connecting sleeve 336, and the pin shaft connecting sleeve 336 is located on the inner side of the support frame 331. The flip side of the lifting plate 332 is connected to the flip plate 333 by a third pin shaft 338. A pressing handle 339 is inserted into the pressing side. The lower part of the flip plate 333 is connected to the middle and lower part of the support frame 331 by a fourth pin shaft 330. When rotating, the lower part of the lifting plate 332 is pressed against or rotated away from the upper part of the support frame 331 extending outward.

[0031] The setting of the flip linkage assembly 33 can flip the lifting plate 332 under the action of power, so as to press the lifting plate 332 against or rotate away from the upper part of the support frame 331 extending outward, so as to achieve the locking or separation of the clamping jaws 34, so as to increase the clamping force of the clamping jaws 34;

[0032] The ends of several clamping jaws 34 and the fixing frame 334 are fixed by fasteners. The arrangement of fixing the clamping jaws 34 and the fixing frame 334 by fasteners allows the clamping jaws 34 to be replaced to solve the problem that the existing clamping jaws 34 are damaged and cannot be replaced and the entire clamping jaw assembly needs to be replaced, thereby effectively reducing the replacement cost of the clamping jaws 34.

[0033] The slide plate 32 is provided with an inclined surface 321 cooperating with a plurality of clamping jaws 34. The setting of the inclined surface 321 of the slide plate 32 can make the inclined surface 321 effectively fit with the bottom surface of the product and reduce the contact area with the product to reduce the possibility of wire drawing.

[0034] One end of the first pin 335, the second pin 337, the third pin 338 and the fourth pin 330 are all provided with a limiting plug bolt with a limiting boss 4. The first pin 335, the second pin 337, the third pin 338 and the fourth pin 330 adopt the setting of a limiting plug bolt with a limiting boss 4, which can effectively limit the position of the pin to improve the stability of the connection between the two connected by the pin, so as to avoid the connection between the two being detached.

[0035] The frame 1 is composed of four brackets 11 , and the four brackets 11 are fixed by connecting members 12 .

[0036] The jaw 34 is made of spring steel. The setting of the jaw 34 being made of spring steel can improve the elasticity of the jaw 34, so that the wear of the lower part of the jaw 34 can also be compensated by the elasticity of the jaw 34 to compensate for the gap between the jaw 34 and the slide plate 32, so as to maintain the clamping force of the product, and at the same time it can also solve the problem that the existing jaws are easy to clamp through the product.

[0037] The workflow of the present invention is:

[0038] The frame 1 is moved to the outside of the product, and the driving mechanisms around the frame 1 simultaneously drive the corresponding telescopic rods 2 to extend and retract in the frame 1. When the product needs to be clamped, after the lifting plate 332 of the flip linkage assembly 33 is subjected to an upward lifting force, the lower part of the lifting plate 332 is away from the upper groove extending outward from the support frame 331, and the pin shaft connecting sleeve 336 rotates accordingly, and the flip plate 333 rotates relatively. The lifting plate 332 is lifted, and the end of the flip plate 333 close to the product flips upward to drive the clamping claw 34 to move upward away from the slide plate 32. After the clamping claw 34 is opened, the driving mechanism pushes the telescopic rod 2 to move toward the inside of the frame 1. The movement of the telescopic rod 2 drives the clamping claw assembly 3 to move toward the product. When it moves to the clamping position of the product, the lifting plate 332 is released. The force is applied, and the clamping jaw 34 slowly moves downward under its own gravity. When the clamping jaw 34 moves close to the product, downward pressure is applied to the lifting plate 332, so that the lower part of the lifting plate 332 is inserted into the upper groove extending outward from the support frame 331, so as to achieve the locking of the clamping jaw 34 and clamp the product at the same time. When the product needs to be transported, the clamp is driven by the moving mechanism to move to the required position to solve the problem that the existing products are always switched to distribute the clamps, causing the products to be easily damaged. At the same time, it also solves the problems that the existing clamps cannot withstand high temperatures, are prone to skewness or cannot be used normally at high temperatures, the movement speed of the clamp cannot be guaranteed, which will cause the material to be pulled out by the clamp, and the skewness or insufficient elasticity of the clamp will easily cause the product to be clamped through.

[0039] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
