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 process.
Background technology
At present, the technology generally adopted in freezer compressor industry is: be fixed on fixture by connecting rod during honing compressor connecting bar, this fixture can the rotating shaft of horizontal and vertical deflection position, hole place's installation two layerings in wanted honing, thus ensure workpiece add man-hour can around two-layer axis of rotation, and also leave certain mobile surplus in the horizontal direction, thus make cutter reach all directions stress equalization between compressor connecting bar hole, hole potential energy ensures there is six-freedom degree man-hour adding, to ensure that tie rod holes ensures that while reaching surface roughness the form and position tolerance of tie rod holes does not make a variation.
As mentioned above, in prior art, position, compressor connecting bar hole Honing process fixture is the cross pivot structure relying on rigidity, is reached the object in biased turn of hole by cross rotating shaft deflection.This structure is because of the limitation of structure, can not ensure that there is the free degree of six direction position, two holes simultaneously, so the every clamping of existing clamp for machining once can only process position, a hole, other fixture and board equipment must be changed during processing second position, 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 of guarantee connecting rod and does not need more to renew special fixture, board.When certain position, hole at honing workpiece of fixture, corresponding workpiece hole position only has independently Workpiece fixing assembly and the backstay that commutates to produce location to it, and workpiece can produce arbitrary deflection and moves thus ensure that stress point reaches balance when the position, hole of honing is stressed.Workpiece other positions, because there will not be mutual interference without stress point or limit point, ensure the form and position tolerance of compressor connecting bar hole in honing process.Equally, when fixture need be switched to other position, hole, Workpiece fixing assembly and the commutation backstay of all correspondences also correspondingly switch, thus the position, hole ensureing the position, hole of needs processing to produce location and do not process produces separation, repetitive cycling processing action.
To achieve these goals, the technical scheme that the present invention takes 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 fixing assembly A, cutter, Workpiece fixing assembly B.Commutation backstay is made up of the backstay A and commutation backstay B that commutates, the two-layer staircase structural model that the table top wherein commutated between backstay A and commutation backstay B rises in middle both sides of sinking.Workpiece fixing assembly A, Workpiece fixing assembly B to be contained in two semicircle floating position-limiting sleeve and to be supported on the table top between commutation backstay A and commutation backstay B.In cyclic process, after the first position, hole machines, commutation backstay A returns, and Workpiece fixing assembly A is corresponding falls to getting out of a predicament or an embarrassing situation of commutation backstay table top; And the backstay B that commutates advances, Workpiece fixing assembly B rises to topping bar of commutation backstay table top, completes switching and makes the second location, machining hole position.
The necessary free degree is obtained for making workpiece to be processed, Workpiece fixing assembly is preferably made up of Workpiece fixing floating seat, flexible member and flexible member positioning seat, namely Workpiece fixing assembly A is made up of Workpiece fixing floating seat A, flexible member A and flexible member positioning seat A, and Workpiece fixing assembly B is made up of Workpiece fixing floating seat B, flexible member B and flexible member positioning seat B.The flexible characteristic of the Workpiece fixing assembly of such composition makes processed hole potential energy along any yaw motion of suffered outer masterpiece.
Flexible member can adopt any applicable element as known in the art, and in preferred embodiments, what flexible member adopted is stage clip.That is, Workpiece fixing assembly B is at this moment made up of Workpiece fixing floating seat A, compression spring A and stage clip positioning seat A, and Workpiece fixing assembly B is made up of Workpiece fixing floating seat B, stage clip B and stage clip positioning seat B.
For when enabling tie rod holes Honing process, compressor connecting bar obtains suitable rotation compensation, can set the tilt value of tie rod holes Honing process mechanism, suitable setting value is-2.0 mm to+2.0 mm.
The present invention adopts technique scheme, and holes clamped one time is also independently processed separately, and the gap quality after improving product assembling, reduces inwall friction; Therefore the requirement that effect reaches consumption reduction synergy is promoted; Reduce unnecessary artificial and machining tool, improve efficiency.On Workpiece fixing floating seat, have employed stage clip syndeton again, take full advantage of flexible, the distortion of stage clip, the characteristic of recovery, ensure that part to be processed obtains the function that can rotate in a desired direction; When compressor connecting bar stretching by stage clip when being subject to out-of-balance force, reversing and be compensated in time and improve the uniform force of honing hole when inwall honing in honing process, reduce the form and position tolerance of tie rod holes.
