Abstract

The utility model discloses a part clamp which comprises a base, wherein a shell and a fixed cone seat are arranged at the top of the base, the shell is positioned at the outer side of the fixed cone seat, an oil storage bin is formed between the shell and the fixed cone seat, a compression oil way communicated with the oil storage bin is formed on the shell, a piston is arranged at the oil storage bin between the shell and the fixed cone seat, and an expansion sleeve is arranged at the inner sides of the piston and the fixed cone seat. According to the utility model, the oil is filled in the compression oil way, the oil quantity of the compression oil storage bin is increased, the piston is pushed downwards, the conical surface of the expansion sleeve is extruded, and the expansion sleeve is contracted inwards to clamp a workpiece; the clamping force on the workpiece is softer, and the damage of rigid parts is avoided.

Description

Part fixture

Technical Field

The utility model relates to the technical field of clamps, in particular to a part clamp.

Background

The disc type thin-wall parts are increasingly widely applied to various industrial fields due to the characteristics of material saving, light weight, compact structure and the like. However, the thin-wall part is weak in strength, poor in rigidity and easy to change, so that the thin-wall part is often unstable in clamping in the preparation process, and thus, the preparation error is caused. Therefore, the clamping device is reasonable in structure, and the clamping-stable clamp is one of indispensable components in the preparation process of disc thin-wall parts.

The prior clamp for the disc thin-wall part disclosed by the publication No. CN208556827U comprises a first clamping assembly, a second clamping assembly and a third clamping assembly, wherein the first clamping assembly comprises a first backing plate and a first compression ring, and the inner diameter of the first compression ring is larger than that of the mounting through hole so as to expose the inner peripheral surface to be processed of the mounting through hole; the second clamping assembly comprises a second backing plate and a second pressing ring, and the cross section area of the second pressing ring is smaller than that of the disc surface of the disc-type thin-wall part so as to expose the outer peripheral surface of the disc-type thin-wall part; the deformation and vibration patterns generated in the processing of the disc thin-wall parts are solved, but for rigid parts, the parts cannot be well protected, and therefore, a part clamp is provided.

Disclosure of Invention

The utility model aims to provide a part clamp which solves the problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a part anchor clamps, includes the base, casing and fixed conical seat are installed at the top of base, and the casing is located the fixed conical seat outside, be formed with the oil storage storehouse between casing and the fixed conical seat, set up the oil circuit that compresses tightly with the oil storage storehouse intercommunication on the casing, the piston is installed to the oil storage storehouse department between casing and the fixed conical seat, the cover that rises is installed to the inboard of piston and fixed conical seat.

Preferably, a 0-shaped sealing ring is arranged between the shell and the base, and a 0-shaped sealing ring is arranged between the fixed conical seat and the base.

Compared with the prior art, the utility model has the beneficial effects that:

1. the oil is filled in the compression oil way, the oil quantity of the compression oil storage bin is increased, the piston is pushed downwards, the conical surface of the expansion sleeve is extruded, and the expansion sleeve is contracted inwards to clamp a workpiece; the clamping force on the workpiece is softer, and the damage of rigid parts is avoided.
