Technical field
The present invention relates to a kind of jig of using during with stock-removing machine cutting machine part, particularly a kind of motor car engine rocker processing chucking appliance.
Background technology
Motor car engine rocker is with stock-removing machine motor car engine rocker casting blank machining to be formed.Motor car engine rocker is a curved boom shape, when the casting blank is processed into product, to cut with a plurality of machined surfaces of stock-removing machine in a plurality of directions of casting blank, process rocker shaft hole, plane, rocker arm shaft aperture, bearing bracket stand, dead eye, hydraulic tappet hole etc., the processing back requires the precision of processing higher.For convenience of machining and assurance machining accuracy, add man-hour at blank, available machining center is to the blank machining, with machining center machining motor car engine rocker blank the time, need the motor car engine rocker blank to be fixed on the jig, again the jig that is fixed with the motor car engine rocker blank is fixed on the machining center landing slab with jig.Jig not only requires the easy to loading and unloading of workpiece as a kind of important instrument, also require workpiece be fixed on the jig back blank stablize indeformable, add when being subjected to cutting force man-hour blank also stablize indeformable, thereby the precision that guarantees processing back workpiece is higher.In the blank process, the structure of jig influence significantly blank loading and unloading and fixing after stable and product processing after precision.In the prior art, the motor car engine rocker processing chucking appliance of using when not being applicable to work in-process heart processing automobile engine rocker.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of motor car engine rocker processing chucking appliance of using when being applicable to work in-process heart processing automobile engine rocker.
The present invention is achieved using the following method.
Motor car engine rocker processing chucking appliance has a left side, right supporting seat, a left side, on the right supporting seat supporting seat axle bed is arranged respectively, a left side, between the right supporting seat rectangular flute profile fixture body is arranged, a fixture body left side along its length, right-hand member has respectively on a left side, jig axon in the right supporting seat axle bed, there is the wafer type band-type brake of jig axon top in the supporting seat axle bed, the left side of the rectangular groove of fixture body, right-hand member has rotating disk respectively, corresponding rotary spacing retaining is arranged respectively between rotating disk and the supporting seat, the bottom land of fixture body is evenly equipped with six～ten chip-removal holes that match with rocker shaft hole along left and right directions, there is filler ring in the aperture on the chip-removal hole on the fixture body bottom land lateral surface, there is the preceding saddle that matches with the front side of motor car engine rocker casting blank in the place ahead, aperture on the chip-removal hole, before there is the edge at the rear, aperture on the chip-removal hole, the rear to the push rod slideway, the push rod that can slide in the push rod slideway is arranged in the push rod slideway, the front end of push rod has the top fork, the rear end of push rod is supported and is connected with the push rod cam that the axle location is connected in the slideway rear side, the spring that makes push rod be subjected to backward directions power is arranged between push rod and push rod slideway, on the chip-removal hole rear in aperture have fulcrum above the push rod slideway before, the rear is to lever, the front end of lever is hinged with presses fork, the rear end of lever is connected with the connecting rod vertical with the fixture body groove bottom, the lower end of connecting rod is supported and is connected with lever and cam, the lever and cam axle pass fixture body before, back trough rim, the front end of lever and cam axle has handwheel.
During use, motor car engine rocker casting blank is placed on filler ring and the preceding saddle, before allowing the front side of blank be placed on the saddle, the rocker shaft hole of blank is relative with chip-removal hole, rotate the push rod cam, allow the top of push rod front end pitch the rear side that is against blank, the handwheel of rotating lever camshaft front end, the push rod cam by connecting rod make the hinged pressure fork of lever front end be pressed in blank above, the rocker shaft hole of blank is in the prong of pressing fork, blank is stuck on the fixture body of the present invention firmly, again the present invention is fixed on the landing slab of metal machining center.
When the wafer type band-type brake of jig axon unclamps in the supporting seat axle bed, stir the left and right end rotating disk of the rectangular groove of fixture body, fixture body can rotate, in the angle that is fit to processing, rotating disk and rotary spacing retaining because of the left and right end of rectangular groove, wafer type band-type brake with the jig axon, allow fixture body be fixed on the angle that is fit to processing, machined surface to a direction of blank carries out machining, the machined surface of a direction is carried out after machining finishes, can change the angle of fixture body, the machined surface of another direction of blank is carried out machining
The present invention has six～ten stations, on each station, as long as rotate the loading and unloading that push rod cam and two cams of lever and cam just can be finished workpiece, workpiece loading and unloading is very convenient, after the motor car engine rocker blank is placed on filler ring of the present invention and the preceding saddle, the forward and backward, upper and lower of blank is subjected to strictly retraining, and stably is stuck on the fixture body, and blank is stuck on the fixture body that the back is stressed rationally can not to produce distortion.
Below in conjunction with accompanying drawing, the present invention is further described.
