Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of precision parts processing, and in particular relates to a placement fixture for precision parts. Background Art
[0002] When processing precision parts, they need to be clamped and fixed on the fixture before operation. The fixture refers to the device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection, also known as a fixture.
[0003] Since conventional clamps completely rely on a spiral method to clamp or loosen precision parts, the spiral operation process is relatively slow, resulting in a problem of low operating efficiency of conventional clamps.
[0004] To this end, we proposed a placement fixture for precision parts to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the problem of low operating efficiency of conventional fixtures and proposes a placement fixture for precision parts.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A clamp for placing precision parts includes a clamp seat, a clamp frame is slidably mounted on the upper part of the clamp seat, a bolt is movably arranged inside the clamp seat, the upper part of the bolt is threadedly engaged with the clamp seat, the bolt is movably connected to the clamp frame, the lower end of the bolt is padded with an elastic seat, and one end of the elastic seat is fixedly connected to the clamp seat. The target precision part is placed between the clamp seat and the clamp frame, and the bolt is pressed downward to make the bolt overcome the elastic force of the elastic seat and swing downward, so that the bolt and the clamp seat lose the threaded connection relationship, and then the bolt is pushed or pulled to drive the clamp frame to move directly until the clamp frame contacts the precision part, and then the lower part of the bolt is held by hand and the bolt is screwed upward to make it move along the clamp seat in a spiral, so that the bolt acts on the clamp frame, and the precision part is clamped and fixed by the clamp frame, which improves the clamping efficiency compared with conventional clamps.
[0008] Preferably, the clamping seat comprises a first clamping block, a seat body, a fixed seat and a guide seat, wherein the first clamping block, the guide seat and the fixed seat are all fixedly connected to the upper end of the seat body. The guide seat is used to guide the sliding of the clamping frame, and when the clamping frame is close to the first clamping block, the first clamping block and the clamping frame are used to conveniently clamp and fix the precision parts.
[0009] Preferably, the elastic seat includes a pad and a spring sheet, the lower end of the pad is fixedly connected to the upper end of the spring sheet, and the elastic force of the spring sheet is used to act upward on the pad, so that the pad acts upward on the bolt, so as to facilitate the bolt and the guide seat to maintain a threaded connection relationship.
[0010] Preferably, a groove is formed at the upper end of the cushion block, so as to increase the contact range between the elastic seat and the bolt.
[0011] Preferably, the clamping frame includes a second clamping block and a sliding rod, and the sliding rod is symmetrically fixedly connected to the outer end of the second clamping block. When the second clamping block moves, the sliding rod constrains the direction of the second clamping block without the clamping frame constraining the direction of the sliding rod, thereby improving the stability of the sliding direction of the clamping frame.
[0012] Preferably, the clamping frame further comprises a clamping plate, which is fixedly connected to the outer end of the second clamping block. The clamping plate is used to increase the contact range between the clamping frame and the target precision component.
[0013] Preferably, the bolt includes a connecting ball, a threaded rod and an operating disk, one end of the threaded rod is fixedly connected to the connecting ball, and the other end of the threaded rod facing away from the connecting ball is fixedly connected to the operating disk. Press the threaded rod downward to make the upper part of the threaded rod lose the threaded connection with the guide seat, then push the operating disk to drive the threaded rod and the connecting ball, and drive the clamp frame to slide through the connecting ball. Hold the lower part of the operating disk and rotate it upward in the forward or reverse direction, so that the threaded rod moves along the spiral in the guide seat, so that the bolt can control the movement of the clamp frame.
[0014] In summary, the technical effects and advantages of the utility model are as follows:
[0015] 1. Place the target precision component between the clamp seat and the clamp frame, press the bolt downward to make the bolt overcome the elastic force of the elastic seat and swing downward, so that the bolt and the clamp seat lose the threaded connection, then push or pull the bolt to drive the clamp frame to move directly until the clamp frame contacts the precision component, then hold the lower part of the bolt and screw the bolt upward to make it move spirally along the clamp seat, so that the bolt acts on the clamp frame, and the precision component is clamped and fixed by the clamp frame, which improves the clamping efficiency compared with conventional clamps.
[0016] 2. Use the elastic force of the spring sheet to act upward on the pad, so that the pad acts upward on the bolt, making it convenient to maintain a threaded connection between the bolt and the guide seat.
[0017] 3. When the second clamping block moves, the direction of the second clamping block is constrained by the sliding rod without the clamping frame constraining the direction of the sliding rod, thereby improving the stability of the sliding direction of the clamping frame.
[0018] 4. Press the threaded rod downward to make the upper part of the threaded rod lose the threaded connection with the guide seat, then push the operating panel to drive the threaded rod and the connecting ball, and drive the clamp to slide through the connecting ball. Hold the lower part of the operating panel and rotate it upward in the forward or reverse direction to make the threaded rod move along the spiral inside the guide seat, so that the bolt can control the movement of the clamp.
