Abstract
The invention discloses the clamping method of a kind of compressor case, relate to machining technique field, use a kind of compressor case clamping device, its step includes: A, dress part: compressor case is loaded onto chuck, its three lateral register boss are individually positioned on three movable jaws of chuck, make compressor case bottom surface abut against with the locating surface of movable jaw；B, holding parts: start movable jaw and control switch, make the lateral compressing block of three movable jaws i.e. be completed by three lateral register boss phase clampings of arcwall face with compressor case.Than prior art, the present invention can solve the part deformation that easily occurs and loosening problem in existing compressor case clamping, processing.
Description
Technical field
The present invention relates to machining technique field, a kind of method for screw compressor casing is carried out clamping.
Background technology
Compressor case is one of basic components important in screw compressor, it has columnar housing, cast by precision by aluminium alloy, play a part support and accommodate various parts, dimensional accuracy and position accuracy demand to compressor case processing are high, and affect part processing precision not only have processing method, also installation way.The generally clamping to compressor case is to use three-jaw chuck, is placed on the three-jaw of three-jaw chuck by compressor case, then after the end face of centering compressor case, opens and controls switch, is clamped by compressor case.There is following deficiency in process of production in this clamping mode: owing to the blank of compressor case is Al-alloy parts, three-jaw chuck is used to carry out clamping, part as excessive in chucking power is susceptible to deformation, part is after unloading, size, positional precision can change and cause, there will be the off-gage phenomenon inconsistent with processing dimension, cause that accepted product percentage is low, production cost increases；As chucking power deficiency part easily loosens, part easily comes off, the hidden danger of generation accident.
Summary of the invention
The technical problem to be solved is to provide the clamping method of a kind of compressor case, and it can solve the part deformation that easily occurs and loosening problem in existing compressor case clamping, processing.
The technical scheme that the present invention provides is: the clamping method of this compressor case, compressor case includes columnar housing, afterbody at described housing is provided with three lateral register boss, the outer surface of described lateral register boss is the arcwall face that higher end is low, one end that described arcwall face is high is positioned at described housing bottom surface, the angle at described arcwall face oblique angle is 4 degree～6 degree, use a kind of compressor case clamping device, this compressor case clamping device includes the chuck being provided with three movable jaws, described movable jaw is provided with locating surface and stretches out the lateral compressing block of described locating surface, the inner surface of described lateral compressing block is the arcwall face that higher end is low, one end that described arcwall face is low is positioned at described locating surface side, the angle at described arcwall face oblique angle is 4 degree～6 degree；
Its step includes:
A, dress part: compressor case is loaded onto chuck, and its three lateral register boss are individually positioned on three movable jaws of chuck, make compressor case bottom surface abut against with the locating surface of movable jaw；
B, holding parts: start movable jaw and control switch, make the lateral compressing block of three movable jaws i.e. be completed by three lateral register boss phase clampings of arcwall face with compressor case.
Owing to have employed technique scheme, the present invention is compared with prior art, having the beneficial effect that owing to being provided with multiple lateral register boss at the afterbody of compressor case housing, the movable jaw of compressor case clamping device sets locating surface and lateral compressing block position is protruding；During clamping, compressor case is put on three movable jaws of chuck, compressor case bottom surface is leaned on the locating surface of flat movable jaw, start movable jaw and control switch, the arcwall face of movable jaw compact heap position projection is made to abut against with the arcwall face of the lateral register boss of compressor case, produce to axle center and to the power of chuck at clamping part, by part firm grip, prevent part work in-process, because the part processing precision that chucking power is excessive or deficiency causes is poor, caducous phenomenon, improves the crudy of part.

Detailed description of the invention
Embodiment 1:
Compressor case as depicted in figs. 1 and 2 includes columnar housing, the present embodiment is provided with three uniform lateral register boss 1 at the afterbody of housing, the outer surface of lateral register boss 1 is the arcwall face that higher end is low, one end that arcwall face is high is positioned at housing bottom surface, and angle b at the compressor case lateral register boss 1 arcwall face oblique angle of the present embodiment is 4 degree.
The clamping method of compressor case, use a kind of compressor case clamping device, this compressor case clamping device compressor case clamping device includes the chuck 2 being provided with three movable jaws 3, movable jaw 3 is provided with locating surface 3-2 and stretches out the lateral compressing block 3-1 of described locating surface 3-2, the inner surface of lateral compressing block 3-1 is the arcwall face that higher end is low, one end that lateral compressing block 3-1 arcwall face is low is positioned at locating surface 3-2 side, angle a at the arcwall face oblique angle of the movable jaw 3 lateral compressing block 3-1 of the present embodiment is 4 degree, as shown in Figure 3, Figure 4；
Its step includes: A, dress part: compressor case is loaded onto chuck, and its three lateral register boss are individually positioned on three movable jaws of chuck, make compressor case bottom surface abut against with the locating surface of movable jaw；B, holding parts:
Start movable jaw and control switch, make the lateral compressing block of three movable jaws i.e. be completed, as shown in Figure 5 by three lateral register boss phase clampings of arcwall face with compressor case.
Embodiment 2:
Angle b at the compressor case lateral register boss 1 arcwall face oblique angle of the present embodiment is 6 degree；Angle a at the arcwall face oblique angle of movable jaw 3 lateral compressing block 3-1 is 6 degree；Other features are same as in Example 1.
