Description

A kind of Hydraulic chuck clamp for brake drum processing
Technical field
The present invention relates to a kind of Hydraulic chuck clamp for brake drum processing, belong to brake drum clamp for machining technical field.
Background technology
Traditional oild chuck is divided into 3 dog chucks or 4 dog chucks, claw is the bloom of trapezium structure, product can be carried out outer clamping or interior clamping, use traditional oild chuck that the brake drum of automobile is clamped and add man-hour, clamping direction cannot be automatically adjusted according to the inside and outside shape of product, need to regulate the central point when levelness of workpiece regulates work pieces process by operator, need repeatedly to reconcile, time-consuming take a lot of work, the technical merit of operator is required higher.And thick, the finish turning of the brake lining of brake drum, reinforcement, dust-proof guard seam, assembling seam and both ends of the surface disposably cannot be completed, add and repeatedly to change clamping plane man-hour, operator to carry repeatedly in the course of processing, operator's labor intensity is big, working (machining) efficiency is low, and machining accuracy can not be guaranteed.
Summary of the invention
It is an object of the invention to, it is provided that a kind of central point automatically finding brake drum in clamping process accurately, it is possible to apparent condition and processing technique according to brake drum are automatically adjusted clamping force;Thick, the finish turning processing of the brake lining of brake drum, reinforcement, dust-proof guard seam, assembling seam and both ends of the surface can be completed after disposable clamping, solve the problem repeatedly changing clamping plane in existing clamping process, thus ensure that machining accuracy, improve the Hydraulic chuck clamp for brake drum processing of working (machining) efficiency.
The present invention is to realize above-mentioned purpose by the following technical solutions:
This Hydraulic chuck clamp being used for brake drum processing is made up of chuck body, basic point block and self-centering deck, it is characterized in that: the upper surface of chuck body has radially made at least six mounting groove, is mounted alternately with basic point block and self-centering deck in six mounting grooves;The inner end of basic point block is equipped with basic point screw rod, and basic point block manually radially can slide in the mounting groove of chuck body upper surface;Self-centering deck is made up of pedestal, swing bolster, crossbeam-rotating axle, two claw rotary shafts, two pieces of pads and two claws, swing bolster is connected with pedestal by crossbeam-rotating axle, crossbeam-rotating axle can rotate in pedestal, swing bolster can swing on crossbeam-rotating axle, and the two ends of swing bolster are separately installed with claw and pad by claw rotary shaft;Claw can rotate in claw rotary shaft up and down.Described basic point block and self-centering deck are at least three.
The present invention having the beneficial effects that compared with prior art:
This Hydraulic chuck clamp being used for brake drum processing can find workpiece centre point automatically accurately, it is ensured that the axiality of clamping workpiece and levelness.And can disposably complete thick, the finish turning processing of the brake lining of brake drum, reinforcement, dust-proof guard seam, assembling seam and both ends of the surface, and improve working (machining) efficiency, compared with conventional brace, time and labour saving, productivity effect improves 2.5 times.This chuck clamps is under the control of Computerized Numerical Control System Program, it is possible to implements high and low pressure and automatically changes, can be automatically adjusted clamping force according to the apparent condition of workpiece and processing technique.During roughing, it is ensured that big processing capacity, by Computerized Numerical Control System Program control, system pressure is set to high pressure;During polish, system pressure first unloads, and chuck jaws time delay is unclamped, and is then converted into low pressure, real rotation secondary clamping.Due to finishing utilization of hour is low pressure, the impact that workpiece is deformed by chucking power reduces, brake lining, the circle of seam are beated and are ensured workpiece stationarity in the course of processing, reduce the deformation that workpiece is caused by the chucking power in clamping process, thus ensure that machining accuracy, decrease employee and change the number of times of face clamping and the number of times of carrying, improve working (machining) efficiency.

Detailed description of the invention
This Hydraulic chuck clamp being used for brake drum processing is made up of chuck body 1, basic point block 7 and self-centering deck, and the upper surface of chuck body 1 has radially made at least six mounting groove, is mounted alternately with basic point block 7 and self-centering deck in six mounting grooves.The inner end of basic point block 7, equipped with basic point screw rod 8, regulates the height of workpiece by adjusting the height of basic point screw rod 8, and basic point block 7 manually radially can slide in the mounting groove of chuck body 1 upper surface.Self-centering deck is made up of pedestal 3, swing bolster 9, crossbeam-rotating axle 2, two pieces of pads 5 of 4, two claw rotary shafts and two claws 6, swing bolster 9 is connected with pedestal 3 by crossbeam-rotating axle 4, crossbeam-rotating axle 4 can rotate in pedestal 3, swing bolster 9 can swing on crossbeam-rotating axle 4, and the two ends of swing bolster 9 are separately installed with claw 6 and pad 5 by claw rotary shaft 2.Claw 6 can rotate in claw rotary shaft 2 up and down.Described basic point block 7 and self-centering deck are at least three (seeing accompanying drawing 1~3).
This Hydraulic chuck clamp work process being used for brake drum processing is, before processing, size according to brake drum, select corresponding pad 5 and claw 6, by hand propelled or pull regulation basic point block 7 to move along the radial direction of chuck body 1, basic point screw rod 8 is made to be directed at the step surface of brake drum workpiece bottom, ensure assembling seam outer face, bottom surface processing dimension, levelness and the level height of brake drum workpiece is controlled by rotating the height of regulation basic point screw rod 8, basic point adjusts and terminates and pad, after claw has been changed, pedestal 3 is controlled to chuck hub slip by the tight loose button of opening of the gripper chuck on display control panel, workpiece is clamped with the swing bolster 9 on moving base 3 and claw 6.In clamping process, according to the feature in product clamping face, swing bolster, by swinging on crossbeam-rotating axle 4 and claw is by swinging up and down in claw rotary shaft 2, can find the central point of brake drum workpiece accurately, it is ensured that the machining accuracy of brake drum workpiece automatically.After process finishing, clicking on the tight loose button of opening of gripper chuck, pedestal slides in and out along chuck radial direction, unclamps workpiece.
The above is presently preferred embodiments of the present invention, the example above explanation not flesh and blood to the present invention makees any pro forma restriction, person of an ordinary skill in the technical field's any simple modification that above detailed description of the invention has been made by the technical spirit of the foundation present invention after having read this specification or deformation, and the technology contents possibly also with the disclosure above is changed or is modified to the Equivalent embodiments of equivalent variations, all still fall within the range of technical solution of the present invention, without departing from the spirit and scope of the invention.
