Description
Technical field
The utility model belongs to the production and processing technical field of Piston Refrigerant Compreessor, and specifically, the utility model relates to a kind of anchor clamps 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 the anchor clamps, these anchor clamps 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 certain mobile surplus in the horizontal direction, 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, compressor connecting bar hole position honing clamp for machining is the cross pivot structure that relies on rigidity in the prior art, reaches the purpose of the biased commentaries on classics 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 anchor clamps and board equipment during position, second hole, this certainly will cause adding, and double artificial and double board equipment is paid in the requirement in man-hour and position, different hole needs special fixture and multiple clamping, causes machining accuracy low.
The utility model content
The problem that the utility model solves provides a kind of Piston Refrigerant Compreessor connecting rod diplopore honing clamp structure, its objective is two hole potential energy honings simultaneously that guarantee connecting rod and does not need more to renew special fixture, board.When certain position, hole at the honing workpiece of anchor clamps, corresponding workpiece hole position has only 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 mutual interference can not occur because of no stress point or spacing point, guarantee the form and position tolerance of compressor connecting bar hole in the honing process.Equally, when anchor clamps 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 utility model is:
Piston Refrigerant Compreessor connecting rod diplopore honing anchor clamps provided by the utility model comprise clamp base, commutation backstay, the unsteady spacing collar of two semicircle, workpiece positioning component A, cutter, workpiece positioning component B.The backstay that commutates is made up of commutation backstay A and commutation backstay B, and the table top that wherein commutates between backstay A and the 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 the unsteady spacing collar of two semicircles and are supported on the table top that commutates between backstay A and the commutation backstay B.In cyclic process, after position, first hole machined, commutation backstay A return, and workpiece positioning component A is corresponding to fall 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, finishes to switch to make location, the second machining hole position.
For making workpiece to be processed obtain the necessary free degree, the workpiece positioning component preferably is made up of workpiece location floating seat, flexible member and flexible member positioning seat, be that workpiece positioning component A is made up of workpiece location floating seat A, flexible member A and flexible member positioning seat A, and workpiece positioning component B is made up of workpiece location floating seat B, flexible member B and flexible member positioning seat B.The flexible characteristic of the workpiece positioning component of Zu Chenging makes processed hole potential energy prolong any yaw motion of suffered outer masterpiece like this.
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 made up of workpiece location floating seat A, compression spring A and stage clip positioning seat A, and workpiece positioning component B is made up of workpiece location 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 utility model adopts technique scheme, the clamping in two holes and independent processing separately, and the gap quality after the assembling of lifting product 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 at workpiece location floating seat again, taken full advantage of the characteristic of stretching, twisting, restoring of stage clip, guaranteed that part to be processed obtains the function that can rotate in required direction; When compressor connecting bar in the honing process, when being subjected to out-of-balance force, can stretching, reverse by stage clip and in time be compensated hole inwall honing when improving honing stressed evenly, reduced the form and position tolerance of tie rod holes.
