Abstract
The utility model discloses a channel positioning numerical control turning fixture for an inner race. The fixture in the utility model overcomes the shortcomings that prior cutting method of inner races has too much positioning modes and procedures and cannot be applied to mass production of high precision. The utility model provides processing method and a tool fixture which have advantages of precise positioning, single procedure production, high precision processing and which can be applied to mass production. The fixture includes a bolt 1, a flange 4, a spring cap 5, a ball case 8, a sliding body 9, a rotary mount 10, a rotator 12, a pressing block 13, a positioning backer, a three-jaw 15, and a stopper 16. The fixture makes the processing reference consistent with the measurement reference and the enables large end face turning and the inner bore processing to be completed at one time on one machine. No reference transition requiring multiple procedures is needed. The channel positioning numerical control turning fixture for inner race has advantages of high reliability and precision, and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool anchor clamps, relates in particular to inner race raceway groove positioning numerical control turning clamp.
Background technology
When existing inner race plane machining and endoporus, measuring basis is on the interior a certain section circle of inner race raceway groove, and the profile of this type products of inner race is a spheroidal, and raceway groove is difficult for location and clamping in circular profile.Existing processing method is: 1, with hand universal machine tools processing, the big plane of an end with inner race is the big cylindrical that the location benchmark is clamped inner race earlier, the facet of the processing other end (the inner race blank all is the cold forging extruding, and the measurement of big plane and its measuring basis cuts circle during extruding has the certain position and the depth of parallelism to require); 2, be the location benchmark with the facet, clamp big cylindrical, the processing large end face puts the processing of large end face shape and size in place.With the facet location, clamp big cylindrical, the processing endoporus puts the endoporus dimensioned in place.4, measure datum level and the size of large end face and the position degree requirement in cylindrical and hole with special measuring tool.
This processing method shortcoming: 1, measuring basis and machining benchmark are inconsistent, need machining benchmark is changed several times.2, manufacturing procedure is many, because it is many to add operation, the processing accumulated error is just big.3, this series products of universal machine tools processing inner race, efficient is slow, can not adapt to high mass throughput processing.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of inner race raceway groove positioning numerical control turning clamp at above-mentioned problems of the prior art, it can pass through design and use cleverly, the locate mode, operation that has overcome the machine cut processing of existing inner race too much, the deficiency of high-precision production and processing in batches, a kind of accurate location, single operation production, high accuracy processing are provided, and can realize processing method and the jig produced in enormous quantities.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of inner race raceway groove positioning numerical control turning clamp comprises: bolt 1, flange 4, spring compressor 5, ball cover 8, slide mass 9, rotary fixing frame 10, rotary body 12, briquetting 13, location backer 14, three-jaw 15, limited block 16;
The angling cylinder of lathe pulling pull bar is being connected bolt 1 with pull bar, drive slide mass 9 again and move backward, and slide mass 9 pulling ball covers 8, ball cover 8 are by the principle design in multi-directional ball joint, can rotate arbitrarily.Ball cover 8 promotes the center rotation of rotary bodies 12 around fixed mount 10, and three-jaw 15 is fixed on the slide mass 9 by briquetting 13, and location backer 14 is installed on the positioning step of centre of clamp body, and three-jaw 15 positions can be adjusted according to the difference of product diameter.
Advantage of the present utility model is: the locate mode that has overcome the machine cut processing of existing inner race, operation is too much, the deficiency of high-precision production and processing in batches, a kind of accurate location is provided, single operation production, high accuracy processing, and can realize the inner race raceway groove positioning numerical control turning clamp produced in enormous quantities, these anchor clamps make machining benchmark consistent with measuring basis, can be on a machine tool endoporus is disposable machines with turning large end face and processing, need not the benchmark conversion of multiple operation, clamping workpiece is reliable, the machining accuracy height is fit to produce in enormous quantities.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, be the structural representation of inner race raceway groove positioning numerical control turning clamp described in the utility model, these anchor clamps comprise: bolt 1, flange 4, spring compressor 5, ball cover 8, slide mass 9, rotary fixing frame 10, rotary body 12, briquetting 13, location backer 14, three-jaw 15, limited block 16.
The angling cylinder of lathe pulling pull bar is being connected bolt 1 with pull bar, drive slide mass 9 again and move backward, and slide mass 9 pulling ball covers 8, ball cover 8 are by the principle design in multi-directional ball joint, can rotate arbitrarily.Ball cover 8 promotes the center rotation of rotary bodies 12 around fixed mount 10, and three-jaw 15 is fixed on the slide mass 9 by briquetting 13, and location backer 14 is installed on the positioning step of centre of clamp body, and three-jaw 15 can be adjusted according to the difference of product diameter.
During clamping, the end face that will need not process is to the anchor clamps end earlier, and the raceway groove position of product is near location backer 14, and three-jaw 15 is crossed the greatest circle (by needing machined surface) of product and located to clamp.During clamping, three-jaw 15 moves the locating surface backer of product to the anchor clamps inner end earlier, and after product and locating surface were close to, three-jaw 15 had the trend of a clamping force again, and product is firmly clamped.After workpiece machines, unclamp anchor clamps, take off product.These anchor clamps need not the benchmark conversion of multiple operation, and clamping workpiece is reliable, and the machining accuracy height is used when being fit to produce in enormous quantities.
It should be noted that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
