Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a stable fixture for processing plate-shaped pure nickel sheets. Background Technology

[0002] Due to their excellent electrical conductivity and corrosion resistance, sheet-shaped pure nickel sheets are widely used in many fields such as electronics, batteries, and aerospace. During the processing of sheet-shaped pure nickel sheets, such as cutting, stamping, and grinding, fixtures and tooling are required to hold them in place to ensure the accuracy and consistency of the processing.

[0003] However, the existing technology has the following drawbacks:

[0004] However, pure nickel sheets are relatively soft, and traditional fixtures use simple clamping methods, which can easily cause indentations, scratches and other damage to the surface of the pure nickel sheets during the clamping process, affecting product quality. On the other hand, the positioning accuracy of existing fixtures is insufficient, and the pure nickel sheets are prone to positional shifts during processing, resulting in large processing dimensional errors and high scrap rates. Utility Model Content

[0005] The purpose of this invention is to provide a stable fixture for processing plate-shaped pure nickel sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable fixture for processing plate-shaped pure nickel sheets, comprising a base, a first support, and a second support. Fixed blocks are fixedly installed at both ends of the bottom of the first support, and are also fixedly installed on one side of the top of the base via the fixed blocks. Second sliding grooves are provided at both ends of the top of the base away from the first support. Slider blocks are provided at both ends of the bottom of the second support, and are slidably installed inside the second sliding grooves. First sliding plates are movably installed at both ends of the top plate of the first support near the second support. A first adjusting bolt is threadedly installed at the center of the end of the first sliding plate away from the first support, and a first pressure plate is rotatably installed at the bottom of the first adjusting bolt. Second sliding plates are movably installed at both ends of the top plate of the second support near the first support. A second adjusting bolt is threadedly installed at the center of the end of the second sliding plate away from the second support, and a second pressure plate is rotatably installed at the bottom of the second adjusting bolt.

[0007] By adopting the above technical solution, the positions of the second support, the first slide plate, and the second slide plate can all be adjusted according to the size of the pure nickel sheet, making it more flexible and expanding its application range.

[0008] Both the first bracket and the second bracket are in a "C" shape with the length of the bottom plate longer than that of the top plate. Buffer pads are bonded to the inner walls of the first bracket, the inner walls of the second bracket, the bottom of the first pressing plate, and the bottom of the second pressing plate, and the buffer pads are made of rubber material.

[0009] Adopting the above technical solution, buffer pads are bonded to the contact surfaces of the brackets and the pressing plates with the pure nickel sheet, which plays a protective role for the pure nickel sheet and can prevent the surface of the pure nickel sheet from being damaged.

[0010] L-shaped fixing plates are fixedly installed on both sides of the second bracket. A threaded through hole is opened in the middle of the bottom of the L-shaped fixing plate, and a fastening bolt is threadedly installed inside the threaded through hole. A rubber head is provided at one end of the fastening bolt close to the base. Grooves are opened on both sides of the base, and the rubber head of the fastening bolt is in close contact with the inner wall of the groove.

[0011] Adopting the above technical solution, by tightening the fastening bolt, the second bracket can be fixed. By loosening the fastening bolt to release the limit, the second bracket can be moved for adjustment.

[0012] First chutes are opened at both ends of the top plate of the first bracket close to the second bracket. A first screw rod is provided in the middle of the first chute. One end of the first screw rod is rotationally connected to the inner wall of one end of the first chute through a rotating connector, and the other end thereof passes through the top plate and is fixedly installed with a gear-shaped rotating handle. A transverse threaded through hole is opened on the side of the first sliding plate away from the first adjusting bolt, and it is sleeved on the outside of the first screw rod.

[0013] Adopting the above technical solution, the gear-shaped rotating handle is convenient for rotating the first screw rod. The first screw rod is threadedly connected to the inner transverse thread of the first sliding plate, and can drive the first sliding plate to move left and right.

[0014] Third chutes are opened at both ends of the top plate of the second bracket close to the first bracket. A second screw rod is provided inside the third chute. One end of the second screw rod is rotationally connected to the inner wall of one end of the third chute through a rotating connector, and the other end thereof passes through the top plate and is fixedly installed with a gear-shaped rotating handle. A transverse threaded through hole is opened on the side of the second sliding plate away from the second adjusting bolt, and it is sleeved on the outside of the second screw rod.

[0015] Adopting the above technical solution, the two third chutes are symmetrically arranged, the second screw rod is rotatable, and the side of the second sliding plate away from the second adjusting bolt is in close fit with the third chute.

[0016] The heights of the top of the bottom plate of the first bracket and the top of the bottom plate of the second bracket are the same. There are gaps between the bottom of the second bracket and the top of the base and between the L-shaped fixing plate and the side wall of the base.

[0017] By adopting the above technical solution, the pure nickel sheet can be placed flat, and the bottom of the second bracket is higher than the top of the base, preventing the two from rubbing against each other and causing damage when the second bracket is moved.

[0018] The base has mounting holes at all four corners, and a floor mat is attached to the bottom of the base. The first bracket and the second bracket are arranged symmetrically.

[0019] The above technical solution provides a convenient mounting hole for fixing fixtures and tools onto the worktable of the processing equipment.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The second support, first slide plate, and second slide plate of this utility model are all slidable, and can be flexibly adjusted and positioned according to different sizes of pure nickel sheets to meet the processing needs of pure nickel sheets of various specifications. The positioning accuracy is high, effectively avoiding positional displacement of pure nickel sheets during processing, improving the accuracy of processing dimensions. The structure is reasonably designed, and the pressure plate can be moved by rotating the handle. The clamping and disassembling of pure nickel sheets is simple and quick, improving processing efficiency. Attached Figure Description
