Abstract
The invention discloses a grinding mechanism of a notch-shaped cylinder hole of a piston type refrigeration compressor base. The grinding mechanism comprises a base, a pull rod and a pull rod guide disc. The pull rod guide disc is fixed above one side of the base, the pull rod transversely penetrates through the pull rod guide disc, an expansion shaft used for fixing a compressor base is arranged at one end of the pull rod close to the base, an expansion sleeve is sleeved on the outer surface of the expansion shaft, a butterfly spring is used for resetting the pull rod is arranged at the other end of the pull rod, the pull rod is connected with the expansion shaft through a hinge, the expansion shaft adjusts radial displacement of the pull rod in micro mode through the hinge, a rotating shaft is further arranged in the pull rod guide disc, and the rotating shaft is connected with the expansion sleeve to drive the expansion sleeve to rotate. The grinding mechanism aims at automatically compensating unbalance stress of cutters caused by a base cylinder hole notch when the cylinder hole is ground, a machined part body deflects slightly through the hinge and the rotating shaft and remove unbalance stress, and the grinding mechanism can ensure form and location tolerance of the cylinder hole of the compressor base in the grinding process.
Description
Technical field
The present invention relates to Compressor Manufacturing field, particularly a kind of Piston Refrigerant Compreessor base breach shape cylinder holes grinding mechanism.
Background technology
At present, the technology generally adopted in freezer compressor industry is: compressor base frame cylinder holes be processed by by fixture and compressor means base fastening, and allow fixture move as parallel direction in the horizontal direction the end of together with, thus make cutter reach all directions stress equalization between compressor base frame cylinder holes, ensure that cylinder holes ensures that while reaching surface roughness the form and position tolerance of cylinder holes does not make a variation.
As shown in Figure 1, be the schematic diagram of the Piston Refrigerant Compreessor base cylinder holes processing grinding mechanism of prior art, wherein, Fig. 1 is structural scheme of mechanism; Fig. 2 be in Fig. 1 A-A to sectional view.
Due to present to energy-saving and cost-reducing and improve the improving constantly of requirement of motor effect, in prior art, compressor base frame cylinder holes must increase by a first quarter moon v notch v to meet the matching requirements of Parts of Compressor, to put existing abrasive structure before this because cylinder holes jagged thus milling cutter is contacted with bore area time generation unequal force, causing cutter to appear in process has deflection; Thus make cutter can not balanced inner hole grinding surface in full process, must occur that the degree of grinding at the upper and lower position of cylinder holes is different, the form and position tolerance of endoporus is caused to depart from, cause cylinder holes to be processed to become inclined hole by original straight hole, consequently increase the resistance of assembling back piston motion; The measure taked as overcome can only be increase fit clearance, and sealing property like this brings adverse effect, causes the usefulness degradation of the moving component such as cylinder holes and piston.。
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Piston Refrigerant Compreessor base breach shape cylinder holes grinding mechanism, when its objective is that cylinder holes is ground, auto-compensation is because the cutter caused by base cylinder holes breach is by force unbalance, the part noumenon of processing is by hinge and rotating shaft, reach slight deflection, thus eliminate unbalanced stressed, ensure the form and position tolerance of compressor base frame cylinder holes in process of lapping.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of Piston Refrigerant Compreessor base breach shape cylinder holes grinding mechanism, comprise base, pull bar and pull bar positioning disk, described pull bar positioning disk is fixed on above base side, pull bar is laterally arranged in pull bar positioning disk, one end that pull bar is close to base is provided with the swelling shaft of fixing compressor base, the sheathed expansion set of swelling shaft outer surface, the pull bar other end is provided with an official document or note spring resetted for pull bar, described pull bar and swelling shaft are connected through the hinge, swelling shaft finely tunes its radial displacement by hinge, a rotating shaft is also provided with in described pull bar positioning disk, rotating shaft is connected with expansion set and drives expansion set to rotate.
As a further improvement on the present invention, be also fixed with a spacing pressing plate inside described pull bar positioning disk and between expansion set, pressing plate is fixed on expansion set, is provided with a stage clip between pressing plate and positioning disk.
The invention has the beneficial effects as follows: the present invention have employed rotating hinge and pivot structure on expansion set and swelling shaft, make swelling shaft can reach slight radial deflection by hinge, expansion set also realizes deflection with the deflection of swelling shaft, ensure that part to be processed obtains the function that can rotate in required direction; The uniform force of the cylinder holes inwall grinding when compressor base frame cylinder holes makes the deflection of compressor base frame entirety when being subject to out-of-balance force by pressing plate and is compensated in time and improves grinding in process of lapping, reduces the form and position tolerance of cylinder holes; The post gap quality of improving product assembling, reduces inwall slip; Promote the requirement that effect reaches consumption reduction synergy.

Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 illustrates a kind of embodiment of a kind of Piston Refrigerant Compreessor of the present invention base breach shape cylinder holes grinding mechanism, comprise base 1, pull bar 10 and pull bar positioning disk 2, described pull bar positioning disk is fixed on above base 1 side, pull bar 10 to be laterally arranged in pull bar positioning disk 2, one end that pull bar 10 is close to base 1 is provided with the swelling shaft 8 for fixing compressor base, the sheathed expansion set 7 of swelling shaft 8 outer surface, pull bar 10 other end is provided with an official document or note spring 3 resetted for pull bar, described pull bar 10 is connected by hinge 4 with swelling shaft 8, swelling shaft 8 finely tunes its radial displacement by hinge 4, a rotating shaft 11 is also provided with in described pull bar positioning disk 2, rotating shaft 11 is connected with expansion set 7 and drives expansion set 7 to rotate, a spacing pressing plate 6 is also fixed with inside described pull bar positioning disk 2 and between expansion set 7, pressing plate 6 is fixed on expansion set 7, a stage clip 5 is provided with between pressing plate 7 and pull bar positioning disk 2.
Swelling shaft can reach slight radial deflection by hinge, the uniform force of the cylinder holes inwall grinding when compressor base frame cylinder holes makes the deflection of compressor base frame entirety when being subject to out-of-balance force by pressing plate and is compensated in time and improves grinding in process of lapping, specifically, its tilt value is: between-0.3 ~+0.3mm, and this mechanism improves and adapts to existing social energy conservation consumption-reducing technological need for change; Form and position tolerance value during compressor base frame cylinder holes attrition process can be reduced, realize Product Process requirement not improving under any process equipment condition; Time grinding force when effectively can compensate compressor base frame cylinder holes attrition process is uneven.
Shown by above implementation column analysis: invention significantly improves piston type compressed machine base cylinder holes grinding technics level; Adopt this kind of new structure, product processing technique can be provided to ensure, reduce because technology equipment is unreasonable and do not reach product design level, meeting product is issued to improved efficiency technological innovation in equal power consumption.
