Abstract
The utility model relates to a hydraulic chuck tool. The innovation points are that the hydraulic chuck tool consists of a body, an elastic sleeve, a sealing plunger and a compression bolt, wherein a mounting sleeve is manufactured at the front end of the body, the elastic sleeve is coaxially sleeved in the mounting sleeve, an annular hydraulic ring is commonly manufactured between the inner wall of the mounting sleeve of the body and the outer wall of the elastic sleeve, a radial oilhole is manufactured on the body, the compression bolt is mounted on the radial oilhole, the sealing plunger is mounted inside the compression bolt of the radial oilhole, a hydraulic oil channel is manufactured inside the body between the annular hydraulic ring and the radial oilhole, and hydraulic oil is packed in the hydraulic oil channel. The utility model has compact structure as well as scientific and reasonable design, and is suitable for machining holes in shafts, worms or similar parts, which have higher requirement on coaxiality with an excircle surface. In addition, by adopting a novel clamping mode to realize accurate positioning of workpieces, the utility model has higher popularization and application value.
Description
Technical field
The utility model belongs to the machined field, particularly a kind of hydraulic chuck frock.
Background technology
At present, in the machining process of axle or worm screw class part, require very high for axial hole and part outer round surface axiality.In the existing processing, adopt soft pawl or dish type chuck that part is carried out the clamping location usually, carry out the processing of axial hole again.In use all there are some drawbacks in existing frock, as, soft pawl is to be welded on the scroll chuck, the structures shape of scroll chuck positioning accuracy (axiality) can not be very high; The clamping force of dish type chuck is inhomogeneous on circumference, makes that clamping the radial position of front and back workpiece on anchor clamps changes easily.Therefore, because the limitation of soft pawl or dish type chuck self structure, part axiality≤the 0.05mm that adopts above-mentioned frock to process, product percent of pass less than 40%, underproof product can only the punching axle cylindrical grinding again, operation and processing cost have been increased undoubtedly, even, still remain to be improved total process back qualification rate again between 85%～90%.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and evenly distributes on the circumference of workpiece, guarantees the accurate location after workpiece clamps, thereby improves the hydraulic chuck frock of product passing rate of processing.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of hydraulic chuck frock, it is characterized in that: mainly constitute by body, resilient sleeve, sealed plunger and hold-down bolt, be shaped on installation sleeve at the body front end, coaxial package one resilient sleeve in this installation sleeve, between body installation sleeve inwall and resilient sleeve outer wall, be shaped on annular hydraulic pressure ring jointly, on body, be shaped on radial direction oil hole, on this radial direction oil hole, hold-down bolt is installed, at the inner sealed plunger of installing of the hold-down bolt of radial direction oil hole, the body interior between annular hydraulic pressure ring and radial direction oil hole is shaped on hydraulic oil channel and encapsulates hydraulic oil.
And, at sealed plunger outer wall coaxial package O type circle.
And described resilient sleeve outer face and body installation sleeve outer face adopt uniform screw to install.
And, at the uniform installing hole that is connected with machine tool chief axis that is shaped on of body periphery.
Advantage of the present utility model and good effect are:
1. this hydraulic chuck tool structure design science is reasonable, adopt hydraulic oil as the medium that transmits clamping force, it has Incoercibility, therefore transmission thrust that can be good, hydraulic oil acts on the resilient sleeve by annular pressure ring, clamping force can evenly distribute on the circumference of workpiece thus, thereby guarantees that workpiece still can keep accurate in locating after clamped, improves machining accuracy.
2. this hydraulic chuck frock is regulated thrust by the hold-down bolt installed on the body, realizes the clamping of workpiece and loosens, and has simple, convenient outstanding advantage; And hold-down bolt acts on hydraulic oil by sealed plunger, and hold-down bolt does not directly contact hydraulic oil, guarantees the sealing of hydraulic oil and the convenience of adjusting.
3. the utility model compact conformation, design science is reasonable, is applicable in axle, worm screw or the like parts and the processing in the coaxial hole of having relatively high expectations of outer round surface, adopts novel installation way to realize the accurate location of workpiece, has higher popularization and application values.
Description of drawings
Fig. 1 is structural representation of the present utility model (cutaway view);
Fig. 2 is the right view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.
A kind of hydraulic chuck frock, its innovation part is: mainly be made of body 5, resilient sleeve 8, sealed plunger 2 and hold-down bolt 1.Be shaped on installation sleeve 7 at the body front end, coaxial package resilient sleeve in this installation sleeve, but place work piece 9 in the resilient sleeve.Resilient sleeve outer face and body installation sleeve outer face adopt uniform screw 11 to install.Between body installation sleeve inwall and resilient sleeve outer wall, be shaped on annular hydraulic pressure ring 6 jointly, on body, be shaped on radial direction oil hole, on this radial direction oil hole, hold-down bolt is installed, at the inner sealed plunger of installing of the hold-down bolt of radial direction oil hole, at plunger outer wall coaxial package O type circle 3.Body interior between annular hydraulic pressure ring and radial direction oil hole is shaped on hydraulic oil channel 4 and encapsulates hydraulic oil.At the uniform installing hole 10 that is connected with machine tool chief axis that is shaped on of body periphery.
The mode of operation of this hydraulic chuck frock is:
1. this hydraulic chuck frock is installed on the lathe spindle, and transfers to installation sleeve axle center and lathe spindle concentric.
2. in the resilient sleeve of workpiece being packed into.
3. rotatably compressing bolt forces sealed plunger to move to the direction that hydraulic oil is arranged, because the sealing function of O type circle, hydraulic oil is sealed in the enclosure space, hydraulic oil has Incoercibility (little compressibility), make the inwall of resilient sleeve be extruded, according to Pascal's law and relevant mechanical knowledge as can be known, hydraulic oil all equates extruding force size on any position of the inwall of resilient sleeve, and direction is pointed to the axis of resilient sleeve, this has just guaranteed all even unanimity of resilient sleeve inner wall deformation, realizes the clamping of workpiece.
4. processing begins and finishes.
5. unclamp hold-down bolt, hydraulic oil forces plunger outward to move, and oil pressure disappears, and resilient sleeve is recovered normal shape.
6. taking-up workpiece, a working cycles finishes.
Through test, reached 99.2% (accumulative total is processed 500, qualified 496) with the qualification rate in hole on the part of hydraulic chuck processing, economic benefit is very considerable.In addition, the succeeding in developing of hydraulic chuck, for the similar part processing of worm screw or axial workpiece many a kind of installation way, be with a wide range of applications.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
