Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and more specifically, to an elastic clamping fixture. Background Technology

[0002] Tooling, also known as process equipment, refers to the general term for all tools used in the manufacturing process. This includes cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, and workstation fixtures. Tooling is its common abbreviation. A fixture is a process device used during machining to quickly secure the workpiece, maintaining the correct relative position of the machine tool, cutting tool, and workpiece. In other words, tooling fixtures are indispensable components of machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent, and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, versatility, and economy.

[0003] There is a workpiece with a planar outer wall on one side and an arc-shaped outer wall on the other. Traditional clamping fixtures are prone to misalignment, resulting in unstable clamping. Moreover, the operation is cumbersome and inconvenient for quick clamping of the workpiece. Therefore, we propose an elastic clamping fixture to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an elastic clamping fixture that can place the workpiece sideways inside the clamping groove, so that the plane of the workpiece fits against the side wall of the clamping groove, and simultaneously align multiple workpieces with each other. Finally, by rotating the locking bolt, the lower support block moves downward at the top opening of the elastic clamping member, thereby causing the top opening of the elastic clamping member to open outward, and thus making the top part of the elastic clamping member tightly fit against the arc surface of the workpiece, completing the clamping of the workpiece. The structure is simple, the operation is convenient, and the workpiece can be clamped quickly.

[0006] 2. Technical Solution

[0012] An elastic clamping component is installed on the inner side of the mounting slot;

[0013] The elastic clamping assembly includes an elastic clamping member placed inside the mounting groove and having a wedge-shaped top opening, a wedge-shaped pressure support block installed on top of the elastic clamping member, a first countersunk hole opened on the pressure support block, and a locking bolt installed inside the first countersunk hole and screwed into the first threaded hole.

[0014] Furthermore, the plane of the workpiece is in contact with the side wall of the clamping groove, and the ends of the plurality of workpieces are aligned with each other.

[0020] 3. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this solution, the elastic clamping component is placed inside the mounting groove, and the locking bolt on the elastic clamping component is screwed into the first threaded hole. First, the elastic clamping component is gently locked, and then the workpiece is placed on its side inside the clamping groove so that the plane of the workpiece is in contact with the side wall of the clamping groove. At the same time, multiple workpieces are aligned with each other. Finally, the locking bolt is rotated so that the lower support block moves downward at the top opening of the elastic clamping component, thereby opening the top opening of the elastic clamping component outward, and then making the top part of the elastic clamping component closely fit with the arc surface of the workpiece, thus completing the clamping of the workpiece. The structure is simple and the operation is convenient, and the workpiece can be clamped quickly.

[0037] Both ends of the clamping groove 3 are provided with mounting grooves 5, and the bottom wall of the mounting groove 5 is provided with a first threaded hole 6 that penetrates the base 1.

[0038] An elastic clamping component is installed on the inner side of the mounting slot 5;

[0039] The elastic clamping assembly includes an elastic clamping member 7 placed inside the mounting groove 5 and having a wedge-shaped top opening, a pressure support block 8 installed on the top of the elastic clamping member 7 and having a wedge-shaped top opening, a first countersunk hole 9 opened on the pressure support block 8, and a locking bolt 10 installed inside the first countersunk hole 9 and screwed into the first threaded hole 6.

[0040] It should be noted that when using this elastic clamping fixture, the elastic clamping component is placed inside the mounting groove 5, and the locking bolt 10 on the elastic clamping component is screwed into the first threaded hole 6. First, the elastic clamping component is gently tightened. Then, the workpiece 4 is placed sideways inside the clamping groove 3, so that the plane of the workpiece 4 is in contact with the side wall of the clamping groove 3. At the same time, multiple workpieces 4 are aligned with each other. Finally, the locking bolt 10 is rotated, so that the lower support block 8 moves downward at the top opening of the elastic clamping component 7, thereby opening the top opening of the elastic clamping component 7 outward, and making the top part of the elastic clamping component 7 tightly fit with the arc surface of the workpiece 4, thus completing the clamping of the workpiece 4. The structure is simple, the operation is convenient, and the clamping of the workpiece 4 can be completed quickly.
