Device for machining small plane of left lock-hook of automobile fifth-wheel part

Abstract

The invention relates to a device for machining a small plane of a left lock-hook of an automobile fifth-wheel part. The device comprises a fixed positioning mechanism, a connecting mechanism and a drive mechanism; the drive mechanism is connected with the fixed positioning mechanism through the connecting mechanism; the fixed positioning mechanism comprises a fixed plate, a positioning plate, a positioning mandrel and a clamp plate; the positioning plate, the positioning mandrel and the clamp plate are disposed on the fixed plate; the positioning plate and the clamp plate are connected and fixed through the positioning mandrel; the clamp plate is composed of two plates facing each other and equal in size; the drive mechanism comprises a drive cylinder, is connected with the clamp plate on the fixed positioning mechanism through the connecting mechanism and drives the clamp plate to open or close. Compared with the prior art, the device has the advantages, such as wide range of application, economy and practicality, simple and practical structure, and convenience in maintenance.

Description

technical field [0001] The invention relates to a processing device for an automobile hook lock, in particular to a processing device for the small plane of the left lock hook of an automobile five-wheel accessory. Background technique [0002] The left lock hook is used in the traction part of the car, and it is one of the main components that require high safety factor assembly accuracy. [0003] At present, the small plane of the left lock hook is processed by a milling machine, and a special mechanical clamping tool is installed on the working table of the milling machine, so that there is no too much space due to the positioning of the product structure. When clamping with a hook wrench during processing, the labor intensity is high, and the clamping force of manual operation is inconsistent, resulting in improper positioning of the workpiece, poor quality stability, and each time the processing is completed, the nut needs to be turned two to three times to make the cla...

Problems solved by technology

When clamping with a hook wrench during processing, the labor intensity is high, and the clamping force of manual operation is inconsistent, resulting in improper positioning of the workpiece, poor quality stability, and each time the processing is completed, the nut needs to be turned two to three times to make the clamping plate and the work The workpiece can only be unloaded if there is enough clearance, the clamping time is long, and the production efficiency is low

[0004] The Chinese patent with the application number 201120559774.X discloses a manufacturing system for automobile lock hook parts. , The first roller, the upper mold core, the first upper mold base, the second process components: the second lower mold base, the second lower mold backing plate, the second lower presser, the second roller, the upper mold presser , The second upper mold base, because various molds need to be used in conjunction with each other, it is easy to be crushed, broken, etc. at the bend, the stability of the parts is poor, and the scrap rate is high. If there are unqualified parts assembled into the body assembly There will be a great risk, or lead to the scrapping of the body assembly, and the sliding friction generated during work will also affect the life of the mold and the stability of the parts, and the production cost and the cost of mold maintenance are relatively high.
