Description
Technical field
The utility model relates to the Precision Machining anchor clamps of the core part-square casing profile of electric main shaft, specifically, relates to a kind of hydraulic pressure milling clamper of multistation Precision Machining square casing.
Background technology
Square casing is the core part of electric main shaft, the height of its quality is directly connected to the assembly precision of electric main shaft, the housing profile generally has the round side of having, circular shell is because of easily manufactured more common, square casing is because of the bigger and less use of manufacture difficulty relatively, it mainly makes difficult point: the one, and be benchmark with the housing inner hole centreline, the depth of parallelism of housing bottom surface and center line is in 0.01mm; The 2nd, the centre-to-centre spacing of housing bottom surface between its endoporus requires in ± 0.01mm.
Summary of the invention
The purpose of utility model provides a kind of hydraulic pressure milling clamper of multistation Precision Machining square casing, can realize the Precision Machining of outline of the square casing of electric main shaft by these anchor clamps.
The technical scheme that realizes above-mentioned purpose is: a kind of hydraulic pressure milling clamper of multistation Precision Machining square casing, by base plate, liquid plastics, mandrel, ringfeder, sealing screw, plunger, adjust screw, cushion block and rhombus pin are formed, ringfeder is sleeved on the mandrel, and with the mandrel interference fit, and the position that is used for the tensioner housing of ringfeder has two sections thin-walleds that separate, cushion block is bearing on the base plate, the end face of cushion block props up mandrel, liquid plastics is filled in the cooperation place of cavity and the mandrel and the ringfeder of mandrel, the front end of plunger props up liquid plastics, adjust screw threads on mandrel, and the front end of adjusting screw props up plunger back-end, sealing screw is spun in the filler opening of liquid plastics on the mandrel, and the rhombus pin is inserted on the ringfeder.
Advantage of the present utility model is as follows: (1) location, reliable clamping, convenience, and utilize a sleeve clamp can finish the processing on four planes, the production efficiency height.(2) clamping force is even, can not destroy machined surface.(3) accuracy of manufacture height, owing to locate with the endoporus self-centering of housing, the foozle of housing endoporus guarantees the uniformity of centre-to-centre spacing size to the almost not influence of its centre-to-centre spacing.(4) anchor clamps are easily manufactured, by the cushion block adjustment anchor clamps center line and the platen depth of parallelism reached in the 0.002mm.(5) these anchor clamps are particularly suitable for the relatively poor Al-alloy casing of rigidity, can improve the system rigidity of housing, reduce housing distortion.(6) these anchor clamps also can be installed in and do the grinding jig use on the surface grinding machine.

The specific embodiment
Below in conjunction with drawings and Examples utility model is described in further detail.
Shown in Fig. 1 ~ 3, a kind of hydraulic pressure milling clamper of multistation Precision Machining square casing, by base plate 1, liquid plastics 3, mandrel 4, ringfeder 5, sealing screw 6, plunger 7, adjust screw 8, cushion block 9 and rhombus pin 10 are formed, ringfeder 5 is sleeved on the mandrel 4, and with mandrel 4 interference fit, and the position that is used for tensioner housing 2 of ringfeder 5 has two sections thin-walleds that separate, cushion block 9 is bearing on the base plate 1, the end face of cushion block 9 props up mandrel 4, liquid plastics 3 is filled in the cooperation place of cavity and the mandrel 4 and the ringfeder 5 of mandrel 4, the front end of plunger 7 props up liquid plastics 3, adjusting screw 8 is spun on the mandrel 4, and the front end of adjusting screw 8 props up plunger 7 rear ends, and sealing screw 6 is spun in the filler opening of liquid plastics on the mandrel, and rhombus pin 10 is inserted on the ringfeder 5.
Use of the present utility model is as follows:
During work, the base plate 1 of anchor clamps is connected by U-lag with the workbench of CNC milling machine (machining center), and housing 2 is enclosed within on the ringfeder 5, insert rhombus pin 10, screw 8 is adjusted in rotation, promotes plunger 7, clamping force evenly is delivered to two chambeies of ringfeder 5 inwalls, makes ringfeder 5 thin-walleds outwards expand clamping work pieces simultaneously, get final product plane of milling, after milling was finished, screw 8 is adjusted in derotation made the ringfeder contraction unclamp housing, half-twist, insert rhombus pin 10, tight housing 2 rises again.For improving the positioning accuracy of anchor clamps, ringfeder 5 tensioner housings 2 parts should be long as far as possible, be divided into two cavitys as far as possible, anchor clamps are with after lathe is connected, amesdial is fixed on the machine tool chief axis, detect ringfeder two ends height with amesdial then, by adjusting cushion block 9, make its reading unanimity,, reduce anchor clamps distortion itself for the clamping accuracy that improves anchor clamps improves the anchor clamps life-span, ringfeder 5 adopts the spring steel vacuum annealing on the one hand, vacuum hardening is handled, satisfy the strain requirement of ringfeder, the cylindrical of finish turning ringfeder 5 again after ringfeder and the mandrel interference assembling guarantees that ringfeder 5 endoporus thin-walled portions are coaxial as far as possible with cylindrical on the other hand.
