Abstract
The utility model discloses a linear cutting clamping apparatus for processing an aperture of an overrun clutch retainer. One end of a mandrel (1) of the clamping apparatus is provided with a spring chuck (4), and the other end is provided with an angular contact bearing (6) and an equal-index plate (2), wherein the outer ring of the angular contact bearing (6) is fixed on a supporting pad (3), and the supporting pad (3) is fixed on a supporting plate (5); the supporting plate (5) is fixed on a linear cutting machine tool body; and a positioning pin (7) is inserted in a positioning pin hole of the equal-index plate (2). The utility model has the advantages of higher equal precision, concentricity of internal diameter and external diameter, and small size index difference of the aperture and can satisfy the requirement for processing the aperture of the high precise overrun clutch retainer.
Description
Technical field
The utility model relates to freewheel clutch retainer fenestra processing technique field, especially a kind of linear cutting clamp of processing freewheel clutch retainer fenestra.
Background technology
Freewheel clutch retainer fenestra divides inside and outside retainer fenestra.Interior fenestra is a rectangle, and outer fenestra is a rectangle band breach form, and in use, inside and outside two retainers play separation and supporting role to the voussoir of freewheel clutch jointly.Common common freewheel clutch is that No. 10 steel plates, the punching presses of 08Al steel plate are made.The fenestra drawing, halving precision is 0.3～0.4mm, and freewheel clutch of having relatively high expectations such as aviation clutch, then use steel alloy, stainless steel to shape through car, mill etc., and require to have certain rigidity, fenestra halving precision to require to below the 0.1mm, so fenestra need adopt the higher processing modes of precision such as line cutting, add the corresponding anchor clamps of needs in man-hour with wire cutting machine and solve in the line cutting process processing of retainer fenestra and five equilibrium problem.
The utility model content
The purpose of this utility model provides a kind of linear cutting clamp of processing freewheel clutch retainer fenestra, has higher halving precision, interior external diameter concentricity, and the advantage that aperture window dimension calibration difference is little can satisfy the processing of high accuracy freewheel clutch retainer fenestra.
The technical solution of the utility model is: described a kind of linear cutting clamp of processing freewheel clutch retainer fenestra, end at the mandrel of these anchor clamps is equipped with spring chuck, the other end is equipped with angular contact bearing and equi-index plate, the outer ring of angular contact bearing all is fixed on the back-up block, back-up block is fixed on the gripper shoe, and gripper shoe is fixed on one's body the wire cutting machine tool.
On the dowel hole of described equi-index plate, be inserted with alignment pin.
Described angular contact bearing is two covers.
The utility model can guarantee clamping of retainer, continuously the retainer fenestra is cut out by the equi-index plate calibration, and requirement such as halving precision, aperture window dimension can reach higher precision, the replaceable different equi-index plate of different five equilibriums can satisfy the processing of high accuracy freewheel clutch retainer fenestra.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in fig. 1, the utility model mainly comprises mandrel 1, equi-index plate 2, back-up block 3, spring chuck 4, gripper shoe 5, angular contact bearing 6; End at mandrel 1 is equipped with spring chuck 4, the other end is equipped with two cover angular contact bearing 6 and equi-index plates 2, on the dowel hole of equi-index plate 2, be inserted with alignment pin 7, the outer ring of two cover angular contact bearings 6 all is fixed on the back-up block 3, back-up block 3 is fixed on the gripper shoe 5, and gripper shoe 5 is fixed on one's body the wire cutting machine tool.Equi-index plate 2 is manufactured with different size according to the quantity that waits the branch fenestra.
Before the utility model work, select equi-index plate 2, and the equi-index plate 2 that chooses is installed on the mandrel 1 according to the quantity that waits the branch fenestra; During work, at first adjust the utility model, make it axial, radial clearance is not more than 0.01mm, rotation freely, the spring chuck axle, circular runout is not more than 0.02mm, to be clipped in through the retainer part of finish turning on the spring chuck 4 then, centering retainer part external diameter and end face, circular runout is not more than 0.02mm, alignment pin 7 is inserted in the dowel hole of equi-index plates 2 the fixedly position of five equilibrium fenestra, the wire cutting machine tool molybdenum filament is drawn just arrived retainer part fenestra center again, by the wire hole that gets out in advance molybdenum filament is put on, cut by the requirement of retainer part aperture window dimension at last, finish the cutting of a fenestra after, extract molybdenum filament out, extract alignment pin 7, rotation equi-index plate 2 to next halving hole inserts dowel hole again, repeats above-mentioned steps again, finishes to the cutting of last fenestra repeatedly.
