Abstract
The invention discloses a compressor shell clamping method and relates to the machining technical field. According to the method, a compressor shell clamping device is used. The method comprises the steps of A, installing a part, wherein a compressor shell is installed on a chuck, and three lateral positioning bosses of the compressor shell are placed on three movable claws of the chuck respectively so that the bottom surface of the compressor shell and the positioning surfaces of the movable claws can be connected in an abutting mode; B, clamping the part, wherein a movable claw control switch is started to enable lateral pressing blocks of the three movable claws to be clamped to the three lateral positioning bosses of the compressor shell through arched surfaces, and then clamping is achieved. Compared with the prior art, the method has the advantage that the problem existing in the prior art that part deformation and looseness occur easily during compressor shell clamping and machining is solved.
Description
Technical field
The present invention relates to machining technique field, especially a kind of for screw compressor casing being carried out to the method for clamping.
Background technology
Compressor case is one of basic components important in screw compressor, the columnar housing of its tool, by aluminium alloy, by precision, cast, play a part to support and containing various parts, dimensional accuracy and position accuracy demand to compressor case processing are high, and affect part processing precision not only have a processing method, also have installation way.Conventionally to the clamping of compressor case, be to adopt three-jaw chuck, compressor case be placed on the three-jaw of three-jaw chuck, then, after the end face of centering compressor case, open gauge tap, compressor case is clamped.There is in process of production following deficiency in this clamping mode: because the blank of compressor case is Al-alloy parts, adopt three-jaw chuck to carry out clamping, part as excessive in chucking power easily deforms, part is after unloading, size, positional precision can change and cause, there will be and the inconsistent off-gage phenomenon of processing dimension, cause that accepted product percentage is low, production cost increases; Part as not enough in chucking power is easily loosening, and part easily comes off, the hidden danger of generation accident.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of clamping method of compressor case, and it can solve the part deformation of easy appearance in existing compressor case clamping, processing and loosening problem.
Technical scheme provided by the invention is: the clamping method of this compressor case, compressor case comprises columnar housing, afterbody at described housing is provided with three lateral register boss, the outer surface of described lateral register boss is the low arcwall face in high one end, one end, 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 comprises the chuck that is provided with three movable jaws, on described movable jaw, be provided with locating surface and the lateral compressing block that stretches out described locating surface, the inner surface of described lateral compressing block is the low arcwall face in high one end, one end, one end that described arcwall face is low is positioned at described locating surface one side, the angle at described arcwall face oblique angle is 4 degree～6 degree,
Its step comprises:
A, dress part: compressor case is loaded onto to chuck, and its three lateral register boss are placed on respectively on three movable jaws of chuck, and the locating surface of compressor case bottom surface and movable jaw is connected;
B, clamping part: start movable jaw gauge tap, the lateral compressing block of three movable jaws is completed by arcwall face and three lateral register boss phases clamping of compressor case.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect having is: because the afterbody at compressor case housing is provided with a plurality of lateral register boss, the movable jaw of compressor case clamping device is set locating surface and lateral compressing block position projection; During clamping, compressor case is put on three movable jaws of chuck, locating surface by compressor case bottom surface by flat movable jaw, start movable jaw gauge tap, the arcwall face of the arcwall face of movable jaw compact heap position projection and the lateral register boss of compressor case is connected, at clamping part, produce to axle center and to the power of chuck, by part clamping firmly, prevent part work in-process, because chucking power is excessive or the not enough part processing precision causing is poor, caducous phenomenon, the crudy of raising part.
