Abstract
The utility model discloses a differential mechanism gear drilling clamp. The differential mechanism gear drilling clamp comprises a base plate (1). A disc-shaped boss (2) is arranged on the upper surface of the base plate (1), and a cylindrical protrusion (3) is arranged in the center of the upper surface of the disc-shaped boss (2). The cylindrical protrusion (3) is sleeved with a pressing plate (4) which is installed above the disc-shaped boss (2), and at least two vertical holes (7) are evenly distributed in the pressing plate (4). The center lines of the holes (7) are located on the outer side of the disc-shaped boss (2). According to the differential mechanism gear drilling clamp, the pressing plate is used for pressing a workpiece, a drill bit is guided through the holes distributed in the pressing plate, the positions of holes in the workpiece are ensured, machining efficiency is effectively improved, and meanwhile the differential mechanism gear drilling clamp has the advantages of being stable in machining size precision, capable of saving cost, simple and safe in operation and the like.
Description
Technical field
The utility model relates to a kind of fixture, particularly relates to a kind of differential gear hole fixture.
Background technology
Differential mechanism is the main part of automobile drive axle, its effect is exactly in the semiaxis transferring power of both sides, allow both sides semiaxis with different rotating speed rotations, meet two sidecar wheels and with the form of pure rolling, do equidistantly not travel as far as possible, reduce the friction on tire and ground.Logical differential mechanism is comprised of parts such as planetary gear, planetary wheel carrier (differential carrier), axle shaft gears, and the power of engine enters differential mechanism through power transmission shaft, directly drives planetary wheel carrier, then drives left and right two semiaxis by planetary gear, drives respectively left and right wheel.And axle shaft gear on differential mechanism need to get out a plurality of holes conventionally on the flank of tooth so that install, because a plurality of holes are to be uniformly distributed along gear centre, higher to the position accuracy demand between each hole.At present on the market a lot of enterprises for this manufacturing procedure if it were not for having bored the position of going to again amount next one hole after a hole, otherwise be exactly directly on workpiece, to mark out the position that needs hole, the machining accuracy of these two kinds of processing modes is all lower, be not easy to reach the required workpiece accuracy requirement of workpiece, therefore need a kind of special fixture to improve the hole machining accuracy of differential gear.
Utility model content
Technical problem to be solved in the utility model is a kind of differential gear boring grab that can improve hole site precision.
The technical solution of the utility model is as follows: a kind of differential gear boring grab, comprise chassis (1), on chassis, (1) upper surface is provided with discoid boss (2), the upper surface center of described discoid boss (2) is provided with column-shaped projection (3), the outer platen (4) that is set with of this column-shaped projection (3), described platen (4) is arranged on the top of discoid boss (2), on this platen (4), be evenly distributed with at least two vertical holes (7), and the center line of this hole (7) is positioned at discoid boss (2) outside.
While using above-mentioned fixture to carry out hole to differential gear, first take off platen, workpiece is placed on chassis, workpiece is sleeved on discoid boss, then load onto platen, make the lower surface of platen be pressed on the upper surface of workpiece, then fixture is placed in to the drill bit below of drilling machine, make drill bit through the workpiece to below platen, carry out hole from hole, bored after one, make platen continue to press workpiece, rolling clamp body, drill bit is stretched into from next hole and carry out hole, because the position distribution in hole is even and fixing, the situation that there will not be the pore size distribution inequality of brill, precision is higher, and do not need to use Digit Control Machine Tool, adopt common driller just can complete operation, saved cost.
In order to facilitate workpiece pressing, the top of described column-shaped projection (3) is provided with vertical double-screw bolt (5), on this double-screw bolt (5), be set with pressing plate (10) and nut (6), and the lower surface of this pressing plate (10) is close to platen (4) upper surface, described nut (6) is positioned at the top of pressing plate (10), and this nut (6) while tightening lower surface be pressed on the upper surface of pressing plate (10).In use, first take off nut, pressing plate and platen, after workpiece is placed, first use platen workpiece pressing, then load onto pressing plate, make pressing plate press platen, then load onto nut, fastening nut, makes nut clamping platen, make to make moving with rolling clamp body, still more enough retaining holes position relative with workpiece.
In order conveniently to rotate or move chuck body, on the outer circumference surface of described chassis (1), be evenly provided with three holding rods (8).
In order further to improve hole precision, in described hole (7), be equiped with orientation drill cover (9).
Beneficial effect: the utility model is used platen by Work-sheet pressing, then by the hole distributing on platen, drill bit is led, guarantee the position in hole on workpiece, when effectively having improved working (machining) efficiency, there is the features such as stable, the cost-saving and safety simple to operate of accurate to dimension.
