Description

Technical Field

[0001] This invention belongs to the field of high-temperature clamping technology, specifically a high-temperature resistant clamp with a micro-unlocking force frame and a retractable function. Background Technology

[0002] When clamping, baking, shaping, and loading / unloading fiberglass composite materials with a thickness of 1.5-3mm, it is necessary to ensure that the clamps do not melt during baking and become unable to grip the material, and also to ensure the movement speed of the clamps during shaping and loading / unloading. If the speed cannot be guaranteed, the material will be pulled out by the clamps. Furthermore, it is also necessary to ensure that the material is not punctured by the clamps after baking. However, existing clamps are prone to melting and bridging during baking, which can cause the clamps to become skewed or unable to grip the material. Skewed clamps can cause the product to be punctured, which seriously affects product quality and leads to defective and scrapped products. Therefore, there is an urgent need to design a high-temperature resistant clamp with a micro-unlocking force frame and a telescopic function to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a high-temperature resistant clamp with a micro-unlocking force frame and a retractable function, which solves the problems mentioned above, such as the existing clamps being unable to withstand high temperatures and being prone to skewing or malfunctioning at high temperatures, the inability to guarantee the clamp's movement speed leading to material being pulled out by the clamp, and the clamp being skewed or having insufficient elasticity, which can easily cause the product to be punctured.

[0004] To solve the above technical problems, the present invention provides a high-temperature resistant clamp with a micro-unlocking force frame and telescopic function, including a frame, several telescopic rods and several gripper assemblies respectively disposed around the frame. The several telescopic rods are respectively inserted through the frame and each telescopic rod is connected to a drive mechanism. The several gripper assemblies are used to grip the product inside the frame cavity.

[0005] Each gripper assembly includes a connecting block, a sliding plate, a flip linkage component, and several grippers. The connecting block is sleeved on the corresponding telescopic rod and fixedly installed with the telescopic rod. The sliding plate is installed on the frame and its bottom is connected to the connecting block. The flip linkage component is installed on the sliding plate. Several grippers are connected to the flip linkage component and are configured to cooperate with the sliding plate.

[0006] Furthermore, the flipping linkage assembly includes a support frame, a lifting plate, a flipping plate, and a fixing frame. The support frame is Z-shaped, with one end fixedly disposed inside the end of the slide plate away from the gripper, and the other end extending outward. A first pin is inserted through the outward-extending end of the support frame. The flipping side of the lifting plate is sleeved on the outside of the pin connecting sleeve, and the two are connected by a second pin. The second pin and the first pin are connected by a pin connecting sleeve, which is located inside the support frame. The flipping side of the lifting plate is connected to the flipping plate by a third pin. A pressing handle is inserted inside the pressing side. The lower part of the flipping plate is connected to the lower middle part of the support frame by a fourth pin. When rotating, the lower part of the lifting plate abuts against or rotates away from the upper outward-extending part of the support frame.

[0007] Furthermore, several of the grippers are fixed to the ends of the fixing frame by fasteners.

[0008] Furthermore, the slide plate is provided with inclined surfaces that engage with a plurality of the grippers.

[0009] Furthermore, one end of the first pin, the second pin, the third pin, and the fourth pin is a limiting plug bolt with a limiting shoulder.

[0010] Furthermore, the frame consists of four supports, which are fixed together by connectors.

[0011] Furthermore, the gripper is made of spring steel.

[0012] The beneficial effects of the present invention are as follows: The clamp of the present invention adopts a clamping method from all four sides inward, and the same driving mechanism can keep the telescopic rods around the frame from extending and retracting evenly to ensure the moving speed of the clamp. The grippers cooperate with or move away from the slide plate under the flipping linkage component to clamp or release the product from all four sides, maintain the stability of the clamp, and solve the problem that uneven clamping force can easily pull and damage the product.

[0013] The flipping linkage component allows the lifting plate to flip under power, so as to press or rotate the lifting plate against or away from the upper part of the outward-extending support frame, thereby locking or separating the grippers and increasing the clamping force of the grippers.

[0014] The clamps and the mounting bracket are fixed together by fasteners, which allows the clamps to be replaced. This solves the problem of replacing the entire clamp assembly when the existing clamps are damaged and cannot be replaced, effectively reducing the replacement cost of the clamps.

[0015] The design of the skateboard's ramp allows it to effectively conform to the bottom surface of the product, while also reducing the contact area and thus minimizing the possibility of stringing.

[0016] The first, second, third, and fourth pins are set with limiting plug bolts with limiting shoulders, which can effectively limit the position of the pins to improve the stability of the connection between the two connected by the pins and prevent the two connected by the pins from separating.

[0017] The use of spring steel for the grippers improves their elasticity, allowing wear on the lower part of the grippers to compensate for the gap between the grippers and the slide plate, thus maintaining the clamping force on the product. It also solves the problem of existing grippers easily puncturing the product. Attached Figure Description

Detailed Implementation

[0026] The technical solutions in the embodiments of the invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] In one specific embodiment of the present invention, such as Figures 1-6 As shown, a high-temperature resistant clamp with a micro-unlocking force frame and telescopic function is disclosed, including a frame 1, several telescopic rods 2 and several gripper assemblies 3 respectively arranged around the frame 1. The several telescopic rods 2 are respectively inserted around the frame 1, and each telescopic rod 2 is connected to a drive mechanism. The several gripper assemblies 3 are used to grip the product inside the cavity of the frame 1.

[0028] Each gripper assembly 3 includes a connecting block 31, a sliding plate 32, a flip linkage assembly 33, and several grippers 34. The connecting block 31 is sleeved on the corresponding telescopic rod 2 and is fixedly installed with the telescopic rod 2. The sliding plate 32 is installed on the frame 1 and its bottom is connected to the connecting block 31. The flip linkage assembly 33 is installed on the sliding plate 32. Several grippers 34 are connected to the flip linkage assembly 33 and are configured to cooperate with the sliding plate 32.

[0029] The clamp of the present invention adopts a clamping method from all four sides inward, and the same driving mechanism can keep the telescopic rods 2 around the frame from extending and retracting evenly to ensure the movement speed of the clamp. The gripper 34 cooperates with or moves away from the slide plate 32 under the flipping linkage component 33 to clamp or release the product from all four sides, maintain the stability of the clamp, and solve the problem that uneven clamp tension can easily pull and damage the product.

[0030] The flipping linkage assembly 33 includes a support frame 331, a lifting plate 332, a flipping plate 333, and a fixing frame 334. The support frame 331 is Z-shaped, with one end fixedly mounted inside the end of the slide plate 32 away from the gripper 34, and the other end extending outward. A first pin 335 passes through the outward-extending end of the support frame 331. The flipping side of the lifting plate 332 is sleeved on the outside of the pin connecting sleeve 336, and the two are connected by a second pin 337. The pin 337 and the first pin 335 are connected by a pin connecting sleeve 336, which is located inside the support frame 331. The flip side of the lifting plate 332 is connected to the flip plate 333 by a third pin 338. A pressing handle 339 is provided inside the pressing side. The lower part of the flip plate 333 is connected to the lower middle part of the support frame 331 by a fourth pin 330. When rotating, the lower part of the lifting plate 332 abuts against or rotates away from the upper part of the support frame 331 that extends outward.

[0031] The flipping linkage component 33 can flip the lifting plate 332 under the action of power, so as to press or rotate the lifting plate 332 against the upper part of the support frame 331 extending outward, so as to lock or separate the gripper 34 and improve the clamping force of the gripper 34.

[0032] Several grippers 34 are fixed to the ends of the fixing frame 334 by fasteners. The fasteners fix the grippers 34 to the fixing frame 334, allowing the grippers 34 to be replaced. This solves the problem that the existing grippers 34 are damaged and cannot be replaced, requiring the replacement of the entire gripper assembly, and effectively reduces the replacement cost of the grippers 34.

[0033] The slide plate 32 is provided with a ramp 321 that cooperates with several grippers 34. The ramp 321 of the slide plate 32 can effectively fit with the bottom surface of the product and reduce the contact area with the product, thereby reducing the possibility of stringing.

[0034] One end of the first pin 335, the second pin 337, the third pin 338, and the fourth pin 330 is a limiting plug bolt with a limiting shoulder 4. The setting of the first pin 335, the second pin 337, the third pin 338, and the fourth pin 330 with limiting plug bolts with limiting shoulders 4 can effectively limit the position of the pins, thereby improving the stability of the connection between the two connected by the pins and preventing the connection from coming apart.

[0035] The frame 1 consists of four supports 11, and the four supports 11 are fixed together by connectors 12.

[0036] The gripper 34 is made of spring steel. The use of spring steel in the gripper 34 can improve the elasticity of the gripper 34. This allows the elasticity of the gripper 34 to compensate for the gap between the gripper 34 and the slide plate 32 when the lower part of the gripper 34 is worn, so as to maintain the clamping force of the product. At the same time, it can also solve the problem that existing grippers are prone to puncturing the product.

[0037] The workflow of this invention:

[0038] When frame 1 is moved to the outside of the product, the various drive mechanisms around frame 1 simultaneously drive the corresponding telescopic rods 2 to extend and retract within frame 1. When clamping the product is required, the lifting plate 332 of the flipping linkage assembly 33 is subjected to an upward lifting force. The lower part of the lifting plate 332 moves away from the upper groove extending outward from the support frame 331, and the pin connecting sleeve 336 rotates accordingly. The flipping plate 333 rotates relative to this, and the lifting plate 332 is lifted. The end of the flipping plate 333 closest to the product flips upward, causing the gripper 34 to move upward away from the slide plate 32. After the gripper 34 opens, the drive mechanism pushes the telescopic rod 2 to move inward to the inside of frame 1. The movement of the telescopic rod 2 causes the gripper assembly 3 to move towards the product. When it moves to the product clamping position, the lifting plate 332 is released. The gripper 34 moves slowly downwards under its own weight. When the gripper 34 moves close to the product, it applies downward pressure to the lifting plate 332, causing the lower part of the lifting plate 332 to engage with the upper groove extending outward from the support frame 331, thereby locking the gripper 34 and clamping the product. When the product needs to be transported, the clamp moves to the required position under the drive of the moving mechanism. This solves the problem of the existing products being constantly rotated and distributed for clamping, which causes the products to be easily damaged. It also solves the problems of the existing clamps being unable to withstand high temperatures and being prone to skewing or malfunctioning at high temperatures, the inability to guarantee the movement speed of the clamps leading to the material being pulled out by the clamps, and the problem of the clamps being skewed or having insufficient elasticity, which can easily cause the product to be punctured.

[0039] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
