Description

Technical Field

[0001] The invention relates to the field of mold processing, and more specifically, to a high-strength and fast gripper. Background Art

[0002] In industrial production, various molds and tools for the required products can be obtained by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. The molds and tools can then be used to produce products, thereby improving production efficiency.

[0003] During the die-casting process, the mold needs to be pressed and cast. At present, the mold is generally pressed and fixed by manual screwing. This production method is often time-consuming. In addition, in some positions where it is difficult to screw, the processing is often difficult, which also leads to the position of the screws not being accurate enough, affecting the quality of the mold.

[0004] Therefore, it is necessary to propose a high-strength and fast gripper to solve the above problems. Summary of the invention

[0005] In order to overcome at least one defect (shortcoming) of the above-mentioned prior art, the present invention provides a high-strength and fast gripper with high precision and convenient operation.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows: a high-strength quick gripper, comprising a clamping plate, a rotating screw, and a clamping gripper and a rotating nut which are sequentially sleeved on the rotating screw, a limiter is provided in the middle of the rotating screw, the clamping plate is arranged on the clamping gripper, the clamping gripper is movably arranged between the rotating nut and the limiter, and is positioned by the rotating nut and the limiter, and the position of the clamping gripper is adjusted by using the limiter and the rotating nut, so that the clamping gripper is clamped on the mold to be processed, thereby pressing and fixing the mold, which reduces the difficulty of processing while also providing processing accuracy.

[0007] Furthermore, the clamping claw includes a clamping claw, a clamping connecting arm and a clamping foot. The clamping claw is connected to the clamping foot via the clamping connecting arm. Through the clamping foot, the clamping claw can be movably set on the rotating screw, and the clamping claw can quickly clamp the casting plate of the mold, thereby facilitating the production of the mold.

[0008] Furthermore, the clamping foot includes a foot body connected to the clamping connecting arm and a connecting positioning column arranged on the foot body, the connecting positioning column is provided with a through hole matching the rotating screw, the foot body is movably sleeved on the rotating screw through the through hole, and the foot body can be movably arranged on the rotating screw through the connecting positioning column, which is simple and convenient and saves production costs.

[0009] Furthermore, the opening of the clamping claw is inclined, and the inclined opening of the clamping claw can be suitable for casting plates of different heights, which is convenient for fixing the clamping claw and pressing the casting plate.

[0010] Furthermore, it also includes a hinge mechanism arranged on the clamping plate, a hinge through hole is provided between the clamping connecting arm and the clamping claw, and the clamping plate is rotatably arranged on the hinge through hole through the hinge mechanism. Through the setting of the hinge mechanism, the clamping plate can be rotated to a certain extent, so that the angle of the clamping plate can be adjusted, which is convenient for clamping mold casting plates of different shapes.

[0011] Furthermore, the hinge mechanism includes a hinge seat and a hinge column arranged on the hinge seat, and the hinge column is rotatably arranged on the hinge through hole. Through the hinge seat and the hinge column, the angle of the clamping plate can be simply adjusted, which is simple and convenient.

[0012] Furthermore, a pressure relief groove is provided on the clamping plate. The provision of the pressure relief groove can provide a certain pressure relief effect during the process of clamping the casting plate, thereby preventing the casting plate from being damaged during the clamping process.

[0013] Furthermore, the pressing plate is provided with a wear-resistant gasket, which can be used to reduce the impact force of the pressing plate on the casting plate, thereby protecting the casting plate and the pressing plate.

[0014] Furthermore, the limiter is a limit block or a limit sleeve. In actual applications, the limit block or the limit sleeve can be set on the rotating screw to locate the position of the clamping claw. It is also possible to only open threads at both ends of the rotating shaft to form a rotating screw when producing the rotating screw. Such a rotating screw has higher strength. In actual applications, other methods can also be used to locate the position of the clamping claw, all of which are within the protection scope of the present invention.

[0015] Furthermore, the stopper and the rotating screw are an integrated structure, and the integrated structure of the stopper and the rotating screw strengthens the connection strength between the stopper and the rotating screw, thereby extending the service life of the rotating screw.

The technical solution of the present invention is further explained below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-2As shown, a high-strength and fast gripper comprises a clamping plate 1, a rotating screw 2, and a clamping gripper 3 and a rotating nut 4 which are sequentially sleeved on the rotating screw 2. A limiter 5 is provided in the middle of the rotating screw 2. The clamping plate 1 is arranged on the clamping gripper 3. The clamping gripper 3 is movably arranged between the rotating nut 4 and the limiter 5, and is positioned by the rotating nut 4 and the limiter 5. The position of the clamping gripper 3 is adjusted by using the limiter 5 and the rotating nut 4, so that the clamping gripper 3 is clamped on the mold to be processed, thereby clamping and fixing the mold, reducing the difficulty of processing while also providing processing accuracy. The clamping gripper 3 comprises a clamping gripper 6, a clamping connecting arm 7 and a clamping foot 8. The clamping gripper 6 is connected to the clamping foot 8 through the clamping connecting arm 7. Through the clamping foot 8, the clamping gripper 6 can be movably arranged on the rotating screw 2, and the clamping gripper 3 can quickly clamp the casting plate 9 of the mold, which is convenient for the production of the mold.

[0028] In the present invention, the clamping foot 8 includes a foot body 10 connected to the clamping connecting arm 7 and a connecting positioning column 11 arranged on the foot body 10. The connecting positioning column 11 is provided with a through hole 12 matching the rotating screw 2. The foot body 10 is movably sleeved on the rotating screw 2 through the through hole 12. The foot body 10 can be movably set on the rotating screw 2 through the connecting positioning column 11, which is simple and convenient and saves production costs. The opening of the clamping claw 6 is inclined, and the inclined opening of the clamping claw 6 can be suitable for casting plates 9 of different heights, which is convenient for fixing the clamping claw 6 and pressing the casting plate 9.

[0029] In addition, it also includes a hinge mechanism arranged on the clamping plate 1, and a hinge through hole 13 is arranged between the clamping connecting arm 7 and the clamping claw 6. The clamping plate 1 is rotatably arranged on the hinge through hole 13 through the hinge mechanism. Through the setting of the hinge mechanism, the clamping plate can be rotated to a certain extent, so that the angle of the clamping plate can be adjusted, which is convenient for clamping mold casting plates of different shapes. The hinge mechanism includes a hinge seat 14 and a hinge column 15 arranged on the hinge seat 14. The hinge column 15 is rotatably arranged on the hinge through hole 13. Through the hinge seat 14 and the hinge column 15, the angle of the clamping plate can be simply adjusted, which is simple and convenient. A pressure relief groove 16 is provided on the clamping plate 1. Through the setting of the pressure relief groove, it can play a certain pressure relief role in the process of clamping the casting plate, thereby preventing the casting plate from being damaged during the clamping process. A wear-resistant gasket is provided on the clamping plate. Through the setting of the wear-resistant gasket, it can be used to reduce the impact force of the clamping plate on the casting plate, thereby protecting the casting plate and the clamping plate.

[0030] In the present invention, the limiter is a limit block or a limit sleeve. In actual applications, the limit block or the limit sleeve can be set on the rotating screw to locate the position of the clamping claw. It is also possible to only open threads at both ends of the rotating shaft to form a rotating screw when producing the rotating screw. Such a rotating screw has higher strength. In actual applications, other methods can also be used to locate the position of the clamping claw, which are all within the protection scope of the present invention. In actual applications, the limiter and the rotating screw are an integrated structure. The integrated structure of the limiter and the rotating screw strengthens the connection strength between the limiter and the rotating screw, thereby extending the service life of the rotating screw.

[0031] Example

[0032] like Figure 3-4 As shown, the high-strength quick gripper is arranged on the panel of the casting plate, wherein the clamping plate squeezes both sides of the casting plate. Since the position of the clamping foot on the rotating screw is adjustable, the position of the clamping foot can be adjusted according to the size of the casting plate. During the adjustment process, it is only necessary to use a tool to rotate the rotating nut so that the rotating nut moves on the rotating screw, and the position of the clamping gripper can be limited with the limiter on the rotating screw, and the clamping gripper is buckled on the bottom plate of the casting plate. When clamping, it is only necessary to adjust the installation height of the high-strength quick gripper on the casting plate panel to complete the clamping. When removing the high-strength quick gripper on the casting plate, it is only necessary to reversely loosen the high-strength quick gripper to complete the disassembly. Compared with the prior art, it is necessary to continuously tighten multiple screws at different positions. The present invention only needs to adjust the installation height of the high-strength quick gripper and the position of the rotating nut to fix the casting plate, which is convenient for the production of the mold. While improving the production speed of the mold, it also reduces the labor intensity of the workers. The high-strength quick gripper is used to clamp the mold, so that the accuracy of the mold is increased.
