Machining clamp for automobile steering knuckle flange end face holes

Abstract

The invention discloses a machining clamp for automobile steering knuckle flange end face holes. On the premise that original technical requirements are met, the machining clamp utilizes the technical characteristic that a shaft part of a part and the end face of a flange are mutually perpendicular, positioning is performed with an accurate reference shaft diameter, it is guaranteed that the axis is perpendicular to drill plates, the flange end face is in a parallel state, and the technical requirements are effectively guaranteed. According to the design of the novel clamp, the two separable drill plates are adopted, when the movable drill plate is pulled open by a hydraulic device, a workpiece is placed between the fixed drill plate and the movable drill plate, the hydraulic device pushes half rings in linkage with the movable drill plate and the fixed drill plate to automatically correct the shaft part of the workpiece along two guide rods and hoop the shaft part on the half ring of the fixed drill plate, so that clamping work is finished. It is sufficiently guaranteed that the two drill plates are in parallel under the limit of the two guide rods, the shaft part is completely kept perpendicular after the workpiece is compressed by the drill plates in parallel, the fixed drill plate is kept still, positioning half rings connected with the drill plates always keep the center of the part unchanged, and therefore the technical requirements are met. Due to the fact that one-off hydraulic clamping is adopted, the time for clamping the part is reduced, one worker can achieve multi-machine operation through an automatic numerical control machining tool, and therefore production cost is reduced.

Description

technical field [0001] The invention relates to an automobile steering knuckle and various parts that must be positioned by the shaft and processed vertically from the direction of the shaft. Background technique [0002] Under the premise of not changing the technical requirements for ensuring the position of the flange end surface porous relative to the shaft reference and the end surface reference, the invention of the processing fixture for the end surface hole of the steering knuckle parts completely replaces the original old-fashioned flip-type drilling jig for Solve the processing problems of low production efficiency, high labor intensity and high production cost. Contents of the invention [0003] The design drawing of the invention fixture is attached figure 1 shown. 1. Hydraulic cylinder (1 piece), 2. Guide rod (2 pieces), 3. Nut (2 pieces), 4. Support plate (1 piece), 5. Screws (8 pieces), 6. Base (1 piece) , 7. Guide sleeve (2 pieces), 8. Movable drilling t...
