Description
Technical field
The invention belongs to the production and processing technical field of Piston Refrigerant Compreessor, specifically, the present invention relates to a kind of fixture for Piston Refrigerant Compreessor connecting rod diplopore honing processing.
Background technology
at present, the technology that generally adopts in the freezer compressor industry is: during the honing compressor connecting bar, connecting rod is fixed on fixture, this fixture install at place, the position, hole of want honing two layerings can horizontal and vertical deflection rotating shaft, thereby guarantee that workpiece can rotate around two-layer rotating shaft adding man-hour, and also leave in the horizontal direction certain mobile surplus, thereby make cutter and the compressor connecting bar hole between reach all directions stress equalization, the hole potential energy guarantees six-freedom degree is arranged adding man-hour, to guarantee that tie rod holes guarantees that when reaching surface roughness the form and position tolerance of tie rod holes does not make a variation.
As mentioned above, in prior art, compressor connecting bar hole position honing clamp for machining is the cross pivot structure that relies on rigidity, reaches the biased purpose that turns in hole by cross rotating shaft deflection.This structure is because of the limitation of structure, can not guarantee that position, two holes has the free degree of six direction simultaneously, so the every clamping of existing clamp for machining once can only be processed position, a hole, processing must be changed other fixture and board equipment during position, second hole, this certainly will cause adding and requires to pay double artificial and double board equipment man-hour and position, different hole needs special fixture and multiple clamping, causes machining accuracy low.
Summary of the invention
The problem that the present invention solves is to provide a kind of Piston Refrigerant Compreessor connecting rod diplopore honing fixture structure, its objective is two hole potential energy honings simultaneously that guarantee connecting rod and does not need more to renew special fixture, board.During certain position, hole when fixture at the honing workpiece, corresponding workpiece hole position only has independently that workpiece positioning component and commutation backstay produce the location to it, thereby and when stressed in the position, hole of honing workpiece can produce deflection arbitrarily and movement guarantees that stress point reaches balance.Thereby other positions of workpiece guarantee the form and position tolerance of compressor connecting bar hole in the honing process because mutual interference not occurring without stress point or limit point.Equally, when fixture need switch to other position, hole, the workpiece positioning component that all are corresponding and commutation backstay also correspondingly switched, and position, the hole generation of not processing thereby assurance needs the position, hole of processing to produce the location separates, the repetitive cycling processing action.
To achieve these goals, the technical scheme taked of the present invention is:
Piston Refrigerant Compreessor connecting rod diplopore honing fixture provided by the present invention comprises clamp base, commutation backstay, two semicircle floating position-limiting sleeve, workpiece positioning component A, cutter, workpiece positioning component B.The backstay that commutates is comprised of commutation backstay A and commutation backstay B, and the table top that wherein commutates between backstay A and commutation backstay B is the two-layer staircase structural model that rise the middle both sides of sinking.Workpiece positioning component A, workpiece positioning component B are contained in two semicircle floating position-limiting sleeves and are supported on the table top that commutates between backstay A and commutation backstay B.In cyclic process, after the first position, hole machined, commutation backstay A return, and workpiece positioning component A is corresponding falls to getting out of a predicament or an embarrassing situation of commutation backstay table top; And commutation backstay B advances, and workpiece positioning component B rises to topping bar of commutation backstay table top, completes to switch to make the second location, machining hole position.
For making workpiece to be processed obtain the necessary free degree, the workpiece positioning component preferably is comprised of workpiece positioning floating seat, flexible member and flexible member positioning seat, be that workpiece positioning component A is comprised of workpiece positioning floating seat A, flexible member A and flexible member positioning seat A, and workpiece positioning component B is comprised of workpiece positioning floating seat B, flexible member B and flexible member positioning seat B.The flexible characteristic of the workpiece positioning component that forms like this makes processed hole potential energy prolong any yaw motion of suffered outer masterpiece.
Flexible member can adopt any suitable element as known in the art, and in preferred embodiments, what flexible member adopted is stage clip.That is, workpiece positioning component B at this moment is comprised of workpiece positioning floating seat A, compression spring A and stage clip positioning seat A, and workpiece positioning component B is comprised of workpiece positioning floating seat B, stage clip B and stage clip positioning seat B.
Can obtain suitable rotation compensation for making the tie rod holes honing add the man-hour compressor connecting bar, can set the tilt value of tie rod holes honing organisation of working, suitable setting value is that-2.0 mm are to+2.0 mm.
The present invention adopts technique scheme, two hole clamped one times and independent processing separately, and the gap quality after the improving product assembling reduces the inwall friction; Therefore promote the requirement that effect reaches consumption reduction synergy; Reduce unnecessary artificial and machining tool, improved efficient.Adopted the stage clip syndeton again on workpiece positioning floating seat, taken full advantage of flexible, the distortion of stage clip, the characteristic of recovery, guaranteed that part to be processed obtains the function that can rotate on required direction; When compressor connecting bar can stretch by stage clip when being subject to out-of-balance force in the honing process, reverse and in time be compensated hole inwall honing when improving honing stressed evenly, reduced the form and position tolerance of tie rod holes.
