Abstract

A hydraulic clamp for cutting machining of a pump head of a high-pressure fuel pump comprises a supporting part in the vertical direction, a first clamping part in the horizontal direction, a second clamping part in the horizontal direction, an inclined wedge horizontal pushing mechanism arranged between the first clamping part in the horizontal direction and the second clamping part in the horizontal direction, and air tightness monitoring devices arranged on the first clamping part and the second clamping part. According to the hydraulic clamp, power in the vertical direction is converted into clamping force in the horizontal direction through the inclined wedge horizontal pushing mechanism, machining of two products is completed through one-time clamping, and the working efficiency is greatly improved; the air tightness monitoring devices are arranged to improve the positioning precision of product clamping, and the situation that the machining precision of a product is low due to the fact that a clamping gap is too large is avoided; and the height of a special wedge-shaped block is lower than that of an installed workpiece, tool collision during tool machining and switching is avoided, invalid production time is shortened, and production efficiency and stability are further improved.

Description

technical field [0001] The invention belongs to the technical field of general machinery, and relates to a hydraulic tooling for a numerically controlled machine tool, in particular to a hydraulic fixture for cutting and processing a pump head of a high-pressure fuel pump. Background technique [0002] The pump head is one of the key parts of the high-pressure fuel pump for automobiles. It is usually manufactured by forging combined with cutting process, and the cutting process is usually carried out on the CNC machining center. [0003] The cutting process of pump head parts in the prior art is usually processed by hydraulic chuck, and only one product can be processed at a time, and the production efficiency is low. In addition, due to the limited structure of the workpiece, the clamping position and positioning requirements are high, and problems such as tool collision and low product processing accuracy are prone to occur. [0004] Aiming at the problems of low producti...
