Description
Technical field
The utility model relates to the anchor clamps that use in the single screw rod type refrigerating compressor guiding valve process, and these anchor clamps are used for the Fast Installation location of the boring arc process of guiding valve.
Background technology
On the existing market, the energy adjustment method that single screw rod type refrigerating compressor is commonly used mostly is guiding valve and regulates.Common sliding valve structure is made of guiding valve body 1 shown in Fig. 1～3, and guiding valve body 1 is provided with the cooperation cambered surface 2 that cooperates with the screw rotor external cylindrical surface, the outer edge surface that cooperates with the compressor internal chamber wall 3 and is cooperating the energy measuring tank of offering on the cambered surface 24.Guiding valve body 1 is the guiding valve rear end near a side of screw rotor exhaust end, and the other end is the guiding valve front end.The rear end of guiding valve has screwed hole 5 vertically, be convenient to threaded rod and penetrate in this screwed hole 5, thereby can by manually, surge or mode such as electronic drives sliding valve movement.The front end edge of guiding valve is axially arranged with pilot hole 6, and the end of this pilot hole 6 is the boss 7 that outwards is convexly equipped with on the guiding valve body 1, and the guide post in the compressor block stretches in this pilot hole 6, and guiding valve is moved back and forth along the screw rotor axial direction.
At present, the processing method of guiding valve is to cast out a blank earlier, processes outer edge surface 3 and boss 7 then thereon, is cooperating cambered surface 2 positions to process a datum plane again, and then on vertical machining centre, datum plane is processed into cooperation cambered surface 2 with boring cutter, reprocessing at last can measuring tank 4.
Cooperate the anchor clamps that use in the process of cambered surface 2 to form in processing by a base plate, a boring ring and pressing plate, the boring ring is fixedly arranged on the base plate, several workpiece placed cavities are circumferentially offered in the inwall upper edge of this boring ring, and the inwall of this workpiece placed cavity is the half-finished outer edge surface coupling of major arc face and guiding valve; Pressing plate is arranged at the top of workpiece placed cavity.During clamping; the half-finished rear end of guiding valve is put into the workpiece placed cavity down; outer edge surface leans on mutually with the inwall of workpiece placed cavity; workpiece is placed and is had randomness; just need the operator to carry out " levelling " step this moment, to guarantee that the half-finished datum plane of guiding valve is perpendicular to the diameter of crossing the outer edge surface center of circle on the boring ring.When " levelling ", earlier with a pull bar along the datum plane coarse positioning, and then about carrying out with amesdial, about after the smoothing, compress through pressing plate again, about carrying out again after compressing, about smoothing verify, could carry out the boring arc to it with boring cutter at last.
Above-mentioned processing and positioning device uses for many years, but must carry out " levelling " to the guiding valve semi-finished product in the process of clamping, need in " levelling " process repeatedly with about the micrometer, about smoothing, cumbersome, the location is accurate inadequately, efficient is lower.Therefore, the utility model provides a kind of single screw rod type refrigerating compressor guiding valve processing and positioning device, to remedy the deficiencies in the prior art from improving the prior art angle.
Summary of the invention
The utility model provides a kind of single screw rod type refrigerating compressor guiding valve anchor clamps, its objective is the existing anchor clamps location trouble of the boring arc process of guiding valve, the problem that precision is not high, efficient is lower of being used for that solve.
For achieving the above object, the technical solution adopted in the utility model is: a kind of single screw rod type refrigerating compressor guiding valve anchor clamps, mainly form by a base plate, a boring ring and several pressing plates, the boring ring is fixedly arranged on the base plate, several workpiece placed cavities are circumferentially offered in the inwall upper edge of this boring ring, and the inwall of these workpiece placed cavities is the half-finished outer edge surface coupling of major arc face and guiding valve; The pressing plate correspondence is arranged on the top of each workpiece placed cavity, corresponding each workpiece placed cavity is provided with the locating hole that embeds for the half-finished boss of guiding valve on the described base plate, 3 corresponding connections in line of the center of circle of the center of circle of locating hole, workpiece placed cavity and the center of circle of boring ring.
Related content in above-mentioned two technical schemes is explained as follows:
1, in the such scheme, described workpiece placed cavity is a major arc shape, and the half-finished outer edge surface of guiding valve cooperates with the inwall of this workpiece placed cavity, and this workpiece placed cavity is to locating on half-finished length of guiding valve and the width.
2, in the such scheme, described pressing plate is provided with resigning hole, and after the guiding valve semi-finished product were put into the workpiece placed cavity, clamping platen by the resigning hole on the pressing plate, can be offered screwed hole in the rear end of guiding valve.
3, in the such scheme, described locating hole is oval locating hole, and the diameter of crossing this ellipse center of circle on the major axis of this ellipse locating hole and the boring ring is vertical.When the guiding valve semi-finished product were put into the workpiece placed cavity, the boss on the guiding valve semi-finished product front end stretched in the described oval locating hole, matches with it.This ellipse locating hole matches with the boss of guiding valve front end on short-axis direction, on the long axis direction with the boss matched in clearance, thereby rotate after the guiding valve semi-finished product from putting into the workpiece placed cavity preventing, also can avoid simultaneously the workpiece placed cavity on width to the half-finished location of crossing of guiding valve.The outer edge surface of the boss that cooperates with oval locating hole is a polished surface.
The utility model beneficial effect compared with prior art is:
1, owing to application of the present utility model, the boring ring inwall of anchor clamps cooperates with the half-finished outer edge surface of guiding valve along the inwall of the major arc shape workpiece placed cavity that circumferentially is provided with, and can accurately locate the guiding valve semi-finished product on length and width; Corresponding each workpiece placed cavity is provided with the locating hole that embeds for the half-finished boss of guiding valve on the base plate of anchor clamps, be provided with because the boss of guiding valve semi-finished product front end and guiding valve are eccentric, thereby after making that the guiding valve semi-finished product are placed in the workpiece placed cavity, boss cooperates with locating hole and can prevent to rotate after the guiding valve semi-finished product from putting into the workpiece placed cavity, and do not need other aids, one side that just can make cooperation cambered surface to be processed on the guiding valve semi-finished product is perpendicular to the diameter of crossing the outer edge surface center of circle on the boring ring, just energy one-time-reach-place of location is installed, simple and fast.
2, because application of the present utility model, when clamping, can one-time-reach-place, need not to carry out " levelling " step again, not be used in repeatedly correction and check, and can guarantee the high accuracy of boring arc.
