Description
Technical field
The present invention relates to field of machining, be specifically related to differential carrier cross axle fixture.
Background technology
Differential mechanism is the vitals of automobile, the structure of its housing and the service behaviour of processing precision direct influence differential mechanism.4 axis hole requirement on machining accuracy for installing cross axle on differential carrier are high, are difficult problems in housing processing.There are some problems in process at present for differential carrier cross axle, the position tolerances such as perpendicularity are had not meet the demands between cross shaft hole, vibration is easily there is in device volume process, and then affect crudy, owing to ceaselessly changing in process and adjusting fixture, make production efficiency low.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, location is reliable, can ensure machining accuracy, the differential carrier cross axle fixture that production efficiency is improved greatly.
Differential carrier cross axle fixture of the present invention, comprise base, described base is provided with two columns, driving oil cylinder is installed between two columns, described driving oil cylinder is provided with a piston rod, the described piston rod other end is fixedly connected with clamp body, described column is through clamp body, and clamp body can slide on column, described column upper end is provided with hold-down nut, a clamping cylinder is provided with in described clamp body, clamping cylinder is provided with a guide draw bar, described guide draw bar upper end is provided with pressure ring, fairlead is provided with between described column and clamp body, clamp body upper end is provided with a positioning sleeve.
Preferably, column is provided with positioning retainer ring.
Preferably, clamp body upper surface is horizontal plane, and all the other each faces are inclined-plane.
Preferably, base is provided with standard water tank.
Structure of the present invention is simple, and location is reliable, can ensure machining accuracy, production efficiency is improved greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of differential carrier cross axle fixture.
Reference numeral: 1-base, 2-drives oil cylinder, 3-piston rod, 4-column, 5-fairlead, 6-clamp body, 7-workpiece, 8-pressure ring, 9-guide draw bar, 10-positioning sleeve, 11-clamping cylinder, 12-positioning retainer ring.
Detailed description of the invention
Differential carrier cross axle fixture of the present invention, comprise base 1, described base 1 is provided with two columns 4, be provided with between two columns 4 and drive oil cylinder 2, described driving oil cylinder 2 is provided with a piston rod 3, described piston rod 3 other end is fixedly connected with clamp body 6, described column 4 is through clamp body 6, and clamp body 6 can slide on column 4, described column 4 upper end is provided with hold-down nut, a clamping cylinder 11 is provided with in described clamp body 6, clamping cylinder 11 is provided with a guide draw bar 9, described guide draw bar 9 upper end is provided with pressure ring 8, fairlead 5 is provided with between described column 4 and clamp body 6, clamp body 6 upper end is provided with a positioning sleeve 10.Clamp body 6 upper surface is horizontal plane, and all the other each faces are inclined-plane.Base 1 is provided with standard water tank.Column 4 is provided with positioning retainer ring 12 to the distance controlling clamp body 6 and move up and down and accuracy.Base l surrounding is the tank of standard, and for the removing of chips, and on clamp body 6, except locating surface horizontal plane, all the other are all inclined-plane, are convenient to chip and fall in the tank of base 1 along clamp body 6.
Add man-hour, workpiece 7 puts into the tram of clamp body 6 along guide draw bar 9, realizes workpiece 7 locate by alignment pin, positioning sleeve lO upper end inner hole surface and end face thereof.Put into pressure ring 8 in guide draw bar 9 upper slot after, the piston of clamping cylinder ll moves downward, drive guide draw bar 9 and pressure ring 8 descending together, thus clamping work pieces 7.Hole, after Drilling operation terminates, the piston rod 3 of oil cylinder 2 is driven to move downward, drive clamp body 6 to move downward, realize the conversion of brill, borer position, after Boring terminates, after piston rod 3 drives clamp body 6 to be up to boring station, the piston rod 3 of clamping cylinder 11 is up, such that the guide draw bar 9 of clamping cylinder is up unclamps workpiece 7, and taking off pressure ring 8 can take out workpiece 7.
