Abstract
The invention relates to a hydraulic chuck clamp used for machining a drum brake, and belongs to the technical field of clamps for machining the drum brake. The hydraulic chuck clamp is composed of a chunk body, base point blocks and automatic centering clamping bases, and the six base point blocks and the six automatic centering clamping bases are alternately installed on the chunk body. A base point screw rod is installed on every base point block; every automatic centering clamping base is composed of a substrate, a rotating beam, a beam rotating shaft, two clamping jaw rotating shafts, two gaskets and two clamping jaws, wherein the rotating beam is connected with the substrate through the bean rotating shaft, and the clamping jaws and the gaskets are installed at the two ends of the rotating beam. The hydraulic chuck clamp can automatically capture the center point of a workpiece, ensure the coaxiality and levelness of workpiece clamping, finish rough and fine turning on a braking face, reinforcing ribs, a spigot of a dust-proof baffle, an assembly spigot and the two end faces of the drum brake in a one-off mode, improve machining efficiency and save time and labor, and the production benefits are improved by 2.5 times. The problems that when the drum brake is machined in a traditional mode, people need to replace clamping planes repeatedly, time and labor are wasted, and machining accuracy can not be ensured are solved.
Description
Technical field
The present invention relates to a kind of oild chuck fixture 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, can carry out outer clamping or interior clamping to product, adopt traditional oild chuck to clamp and add man-hour the brake drum of automobile, cannot automatically regulate clamping direction according to the inside and outside shape of product, need to regulate the levelness of workpiece to regulate workpiece to add the central point in man-hour by operator, need to repeatedly reconcile, time-consuming taking a lot of work, has relatively high expectations to operator's technical merit.And cannot to the brake lining of brake drum, reinforcement, dust-proof guard seam, assembling seam and both ends of the surface thick, finish turning is disposable completes, add and will repeatedly change clamping plane man-hour, operator will carry repeatedly in process, operator's labour intensity is large, working (machining) efficiency is low, and machining accuracy can not be guaranteed.
Summary of the invention
The object of the invention is to, a kind of central point of automatically finding brake drum in clamping process accurately is provided, can automatically regulate clamping force according to the surface state of brake drum and processing technology; After disposable clamping, can complete thick, the finish turning processing of brake lining, reinforcement, dust-proof guard seam, assembling seam and the both ends of the surface of brake drum, solved the problem that will repeatedly change clamping plane in existing clamping process, thereby guaranteed machining accuracy, improved the oild chuck fixture for brake drum processing of working (machining) efficiency.
The present invention realizes above-mentioned purpose by the following technical solutions:
Should by chuck body, basic point piece and self-centering deck, be formed for the oild chuck fixture of brake drum processing, it is characterized in that: the upper surface of chuck body is radially manufactured with at least six mounting grooves, in six mounting grooves, be mounted alternately with basic point piece and self-centering deck; Basic point screw rod is equipped with in the inner end of basic point piece, and basic point piece radially slides in the mounting groove of chuck body upper surface by manual energy; Self-centering deck is comprised of pedestal, swing bolster, crossbeam-rotating axle, two claw rotating shafts, two 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 rotating shaft; Claw can rotation up and down on claw rotating shaft.Described basic point piece and self-centering deck are at least three.
The present invention's beneficial effect is compared with prior art:
Should can automatically find workpiece centre point accurately for the oild chuck fixture of brake drum processing, guarantee axiality and the levelness of clamping workpiece.And disposable thick, the finish turning processing that complete brake lining, reinforcement, dust-proof guard seam, assembling seam and the both ends of the surface of brake drum of energy, improved working (machining) efficiency, compare with conventional brace, time and labour saving, productivity effect has improved 2.5 times.This chuck clamps, under the control of Computerized Numerical Control System Program, can be implemented high and low pressure and automatically change, and can automatically regulate clamping force according to the surface state of workpiece and processing technology.During roughing, guarantee large processing capacity, by Computerized Numerical Control System Program, control, system pressure is set to high pressure; During fine finishining, system pressure first unloads, and chuck jaws time delay is unclamped, and is then transformed to low pressure, revolves in fact secondary and clamps.Due to finishing utilization of hour is low pressure, chucking power reduces the impact of workpiece deformation, the circle of brake lining, seam is beated and is guaranteed the stationarity of workpiece in process, reduce the distortion that the chucking power in clamping process causes workpiece, thereby guaranteed machining accuracy, reduce employee and changed the number of times of face clamping and the number of times of carrying, improved working (machining) efficiency.
