The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, machining large box parts special-purpose vehicle boring fixture, comprise cushion block body 1, clamping press plate 9, locating piece 2 and moving press plate 4, on described cushion block body upper surface, by securing member, be equipped with for box parts location and fixing clamping press plate 8, in described cushion block body anterior end surface, be provided with for measuring locating piece 2 and the locating hole 10 of box parts hole and end face distance, the four corners position of described cushion block body anterior end surface is respectively equipped with moving press plate 5.Described locating piece 2 is fixed by soket head cap screw 7 and cushion block body.
In the present embodiment, in described cushion block body anterior end surface, be shaped with the groove 11 for coordinating with the protruding key of box parts.
In the present embodiment, the side end face of described cushion block body one side for matching with platen, the side end face of another side for matching with placement box parts, the side end face that described cushion block body matches with platen and cushion block body are the face of being parallel to each other with the side end face that placement box parts matches, and the nonparallelism franchise of both sides end face is 0.01mm.
In the present embodiment, between the locating piece 2 in described cushion block body anterior end surface and locating hole 10, be provided with box parts on the distance that matches of dead eye 13 and its end distance.
In the present embodiment, between the groove 11 in described cushion block body anterior end surface and locating hole 10, be provided with and box parts on dead eye 13 and protruding key 15 between the distance that matches of spacing.
Because the mutual nonparallelism of boring fixture left and right sides end face is controlled in 0.01mm, the mutual non-perpendicularity in left end face and bottom surface is equally also controlled in 0.01mm, so this has just guaranteed the datum level of part to be processed and the uniformity of boring fixture datum, boring fixture is provided with locating hole 10 and groove 11, the distance of locating hole and locating piece 2 and fixing with the distance of groove 11, and match with the desired size of part to be processed.Described clamping press plate 8 is that described moving press plate 4 is arranged on boring fixture four corners position, can part to be processed easy to setup for the stability of further firm part to be processed.
Operation principle of the present utility model is:
Refer to Fig. 4-Fig. 5, first the hole of machining box part and end face on vertical lathe, during clamping, car boring fixture left end face is placed on vertical lathe workstation face as datum level, its right end face clamping box parts (part of double dot dash line shown in Fig. 5), and by clamping press plate 8 and six square toes trip bolts 9, box parts 12 and the top of this boring fixture are fixed, then by moving press plate 4, adjusting support pin 3, hexagon thin nut 6, packing ring 5, box parts and this boring fixture anterior end surface are fixed.Because boring fixture left and right sides end face nonparallelism franchise is controlled in 0.01mm, so guaranteed the datum level of box parts and the uniformity of car boring fixture datum, the protruding key of box parts is placed in fixture groove, according to the location dimension shown in Fig. 1, dead eye 13 and the end face of machining box part, then in the situation that box parts and fixture still maintain the original state, integral body is pulled down from vertical lathe, will fixture left end face be placed on horizontal Machining centers work top, press dead eye 13 centerings in 0.01mm, according to dead eye 13 and locating piece 2 displacement processing transmission axis hole 14 and end faces.Because design is during fixture, all desired location dimensions all match with box parts, thus when machining box part, not only save time, laborsaving, assurance machining accuracy, and this car boring fixture can also use on different lathes, saved fund.
