Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a metal product processing clamp. Background Art

[0002] During the processing of metal products, it is necessary to ensure that they always remain in the set position, so a clamp is needed to clamp and fix the metal products. According to a metal product processing clamp described in Chinese patent document CN202222627275.0, the disclosed technical solution drives the motor and the metal product carrier plate to move up and down through an electric telescopic rod, thereby driving the metal product to move up and down, and can adjust the height of the metal product as needed. The motor drives the rotating shaft and the metal product carrier plate to rotate, thereby driving the metal product to rotate, without manual adjustment, so that the clamp clamps the metal product under the action of the electric push rod, thereby improving work efficiency.

[0003] According to the technical solution disclosed by the technology, after the clamp used for metal product processing in the prior art is clamped, the metal product workpiece cannot be moved due to the influence of static friction and can only move synchronously with the clamping structure. Therefore, the clamping position is always covered by the clamping structure, resulting in the subsequent processing range being unable to include the clamping area, thereby reducing the processable range. On the other hand, it is difficult to accurately control the clamping point to be in the center position through clamping through a threaded structure. Although the spring structure can control the position of the workpiece and achieve rapid unfolding and clamping effects, it also needs to apply a greater pulling force when unfolding, so the clamping operation process is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a metal product processing clamp to solve the problems raised in the above-mentioned background technology. After clamping, the utility model can still control the workpiece to be pulled in the horizontal direction, thereby changing the clamping position without releasing the clamping effect, and is more convenient to use.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a metal product processing fixture, including a processing fixture body, the processing fixture body including a base plate, a telescopic mechanism, a clamping assembly and a reset mechanism, end plates are installed at both ends of the base plate, the telescopic mechanism is installed on the inner side of the end plate, a clamping assembly is installed at the end of each telescopic mechanism, a lifting assembly is installed on the surface of the base plate, a reset mechanism is installed at the bottom of one of the telescopic mechanisms, and the reset mechanism passes through the inside of one of the end plates.

[0006] Furthermore, the telescopic mechanism includes a telescopic sleeve and a telescopic rod, a spring is sleeved on one end of the surface of the telescopic rod, a limiting convex ring is installed in the middle of one of the telescopic rods, and the clamping assembly is installed at the end of the telescopic rod.

[0007] Furthermore, the clamping assembly includes a connecting frame and a top plate, wherein the top plate is installed on the inner side of the connecting frame, rolling sleeves are arranged at both ends of the top plate, and a rotating belt is wound around the side of the rolling sleeve.

[0008] Furthermore, the top plate fits against the inner side of the rotating belt, the end of the telescopic rod and the spring are embedded in the telescopic sleeve, one end of the telescopic sleeve is welded to the surface of the end plate as a whole, and the two ends of the spring are fixedly connected to the telescopic rod and the telescopic sleeve respectively.

[0009] Furthermore, the reset mechanism includes a screw rod, a top connecting plate and a bottom connecting plate, a hand wheel is installed at one end of the screw rod, the screw rod passes through the inside of the end plate, and a threaded sleeve is sleeved on the surface of the screw rod.

[0010] Furthermore, the bottom connecting plate is installed at one end of the threaded sleeve, and a top connecting plate is arranged on the top of the bottom connecting plate, and the top connecting plate is sleeved on the surface of the telescopic rod.

[0011] Furthermore, the lifting assembly includes a base and a support plate, a threaded hole is opened in the middle of the base, and a threaded rod is connected to the bottom of the support plate.

[0012] Furthermore, the support plate is embedded into the threaded hole through the threaded rod at the bottom, and the lifting component is arranged on one side of the bottom plate.

[0013] Beneficial effects of the utility model:

[0014] The metal product processing fixture is equipped with a rotating belt in the clamping assembly, and the two sides of the workpiece are clamped by the rotating belt. Therefore, after clamping, the clamping belt can still be rotated by pulling the workpiece, thereby changing the clamped area. Therefore, without dismantling, the range that can be directly exposed for processing can be expanded by replacing the clamping range, eliminating processing dead angles.

[0015] The metal product processing fixture can control the advancement of the clamping component at the end through the spring inside the telescopic mechanism, thereby achieving the clamping effect. After clamping is completed, since the spring specifications inside the two clamping components are the same, it can ensure that the clamped workpiece can automatically move to the middle position, and cooperate with the lifting component fixed at the bottom to adjust the height of the workpiece. Therefore, the external processing equipment does not need to adjust the position, and it is more convenient to use.

[0016] The metal product processing fixture controls one of the telescopic mechanisms to move through a reset mechanism, so the resistance effect generated by the spring can be reduced through rotation, making the process of unfolding the two telescopic mechanisms more labor-saving.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a metal product processing fixture, including a processing fixture body, the processing fixture body includes a base plate 1, a telescopic mechanism 3, a clamping assembly 4 and a reset mechanism 5, end plates 2 are installed at both ends of the base plate 1, the telescopic mechanism 3 is installed on the inner side of the end plate 2, the clamping assembly 4 is installed at the end of each telescopic mechanism 3, a lifting assembly 6 is installed on the surface of the base plate 1, and a reset mechanism 5 is installed at the bottom of one of the telescopic mechanisms 3, and the reset mechanism 5 passes through the inside of one of the end plates 2. The metal product processing fixture includes a processing fixture body, the processing fixture body includes a base plate 1, a telescopic mechanism 3, a clamping assembly 4 and a reset mechanism 5. When in use, one of the telescopic mechanisms 3 is pulled to shrink by rotating the reset mechanism 5 until it passes over the top of the bottom lifting assembly 6, and then the metal product workpiece to be processed can be placed on the top of the lifting assembly 6, and at this time, the reset mechanism 5 is controlled to release the pulling effect on the telescopic mechanism 3, and the clamping process of the workpiece can be realized by the telescopic mechanisms 3 and the clamping assembly 4 on both sides.

[0024] In this embodiment, the telescopic mechanism 3 includes a telescopic sleeve 7 and a telescopic rod 8, one end of the surface of the telescopic rod 8 is sleeved with a spring 9, a limiting convex ring 10 is installed in the middle of one of the telescopic rods 8, and the clamping assembly 4 is installed at the end of the telescopic rod 8. The clamping assembly 4 includes a connecting frame 11 and a top plate 12, and the top plate 12 is installed on the inner side of the connecting frame 11. Rolling sleeves 13 are provided at both ends of the top plate 12, and a rotating belt 14 is wound around the side of the rolling sleeve 13. The top plate 12 fits with the inner side of the rotating belt 14, and the end of the telescopic rod 8 and the spring 9 are embedded in the interior of the telescopic sleeve 7. One end of the telescopic sleeve 7 is welded to the surface of the end plate 2 as a whole, and the two ends of the spring 9 are respectively fixedly connected to the telescopic rod 8 and the telescopic sleeve 7. A rotating belt 14 is installed in the clamping assembly 4, and the two sides of the workpiece are clamped by the rotating belt 14. Therefore, after clamping, the clamping belt can still be rotated by pulling the workpiece, thereby changing the clamped area range. Therefore, without dismantling, the range that can be directly exposed for processing can be expanded by replacing the clamping range, eliminating processing dead angles.

[0025] Specifically, when one of the telescopic mechanisms 3 is pulled and retracted by the reset mechanism 5, the other telescopic mechanism 3 will push the internal telescopic rod 8 toward the outside under the action of the spring 9 until the entire spring 9 reaches the initial state. At this time, the clamping assembly 4 at the end of the telescopic mechanism 3 is aligned with the lifting assembly 6, and then the reset mechanism 5 can be controlled to coordinate the other telescopic mechanism 3 and the clamping assembly 4 to achieve the clamping effect on the workpiece. After the clamping is completed, since the clamping assembly 4 achieves the clamping effect on the workpiece through the inner rotating belt 14, directly pulling the workpiece can drive the rotating belt 14 to rotate, thereby changing the clamped area on the workpiece surface.

[0026] In this embodiment, the reset mechanism 5 includes a screw rod 15, a top connection plate 18 and a bottom connection plate 17, a hand wheel 16 is installed at one end of the screw rod 15, the screw rod 15 passes through the inside of the end plate 2, a threaded sleeve 19 is sleeved on the surface of the screw rod 15, the bottom connection plate 17 is installed on one end of the threaded sleeve 19, a top connection plate 18 is arranged on the top of the bottom connection plate 17, and the top connection plate 18 is sleeved on the surface of the telescopic rod 8. The reset mechanism 5 controls one of the telescopic mechanisms 3 to move, so the resistance effect of the spring 9 can be reduced by rotating, making the process of unfolding the two telescopic mechanisms 3 more labor-saving.

[0027] Specifically, by controlling the handwheel 16 on the reset mechanism 5 to rotate, the screw rod 15 can be controlled to rotate, and the threaded sleeve 19 at the end and the bottom connecting plate 17 are pulled toward the position of the end plate 2 until the top connecting plate 18 is pressed against the limiting convex ring 10 of the upper telescopic mechanism 3. At this time, the handwheel 16 is continued to be rotated, and the top telescopic rod 8 can be finally pulled toward the position of the end plate 2 through the screw rod 15 and the connecting plate until the internal spring 9 is compressed, thereby realizing the expansion process of the two clamping components 4.

[0028] In this embodiment, the lifting assembly 6 includes a base 20 and a support plate 23. A threaded hole 21 is provided in the middle of the base 20. A threaded rod 22 is connected to the bottom of the support plate 23. The support plate 23 is embedded in the threaded hole 21 through the threaded rod 22 at the bottom. The lifting assembly 6 is arranged on one side of the bottom plate 1. The spring 9 inside the telescopic mechanism 3 can control the advancement of the clamping assembly 4 at the end to achieve the clamping effect. After the clamping is completed, since the springs 9 inside the two clamping assemblies 4 have the same specifications, it can ensure that the clamped workpiece can automatically move to the middle position, and cooperate with the lifting assembly 6 fixed at the bottom to adjust the height of the workpiece, so that the external processing equipment does not need to adjust the position, and it is more convenient to use. Specifically, after the workpiece is clamped through the above process, the workpiece is still placed on the support plate 23. With the reverse rotation of the handwheel 16, the screw rod 15 is rotated to control the top connecting plate 18 to move in the opposite direction of the limiting convex ring 10, and the top telescopic mechanism 3 can be slowly unblocked. In this process, the clamped workpiece will be slowly moved toward the middle through the two telescopic mechanisms 3 and the clamping assembly 4 until the top connecting plate 18 is completely disengaged from the limiting convex ring 10, at which time the workpiece can be automatically moved to the center point of the clamp.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
