Description
Technical field
The utility model is related to hole drilling positioning fixture technical field, particularly belong to it is a kind of for heavy truck back axle shell pieces drilling
Special tooling.
Background technology
Vehicle rear-axle housing is the important component of automobile, and it is constituted with main reducing gear, differential mechanism and wheel drive
Drive axle.Drive axle is in the end of PWTN, and its motor-driven function is the torque that increase is transmitted by power transmission shaft or speed changer,
And power is reasonably distributed to left and right driving wheel, Drive axle housing is bearing part and force transmission element important on automobile in addition.Drive
The axle housing of dynamic bridge not only supports vehicle weight, transfers load to wheel, and also subject to leading for being passed over by driving moment
Gravitation, brake force, side force, the counter-force of vertical force and countertorque, and it is transmitted to vehicle frame or vehicle body through suspension.Crossed in garage
Cheng Zhong, ever-changing due to road conditions, axle housing is influenceed by the shock loading produced between wheel and ground, may cause
Axle housing deforms or fractures.Therefore, driving axle housing should have enough intensity, rigidity and good dynamic characteristic, reasonable design
Manufacture driving axle housing is the important measures for improving Riding Stability of Automobile, and vehicle rear-axle housing is widely used in the middle of various vehicles.
Wherein back axle shell pieces requirement drills in its cambered surface, and boring positioning is very difficult, and processing efficiency is than relatively low.
Utility model content
The purpose of this utility model there is provided a kind of special tooling for the drilling of heavy truck back axle shell pieces, overcome existing
The deficiency of technology, frock main body is made up of two pieces of arcs being parallel to each other, radian and rear axle housing to be processed below arc
Piece top radian is consistent, is positioned using back axle shell pieces top radian to be processed, is carried out by the spacing connecting plate of two sides
Secondary positioning, while being provided with the boring positioning block of activity between two pieces of arcs, positions convenient and swift, reduction cambered surface hole positioning
Difficulty, improves the efficiency of back axle shell pieces cambered surface hole.
To solve the above problems, technical solution adopted in the utility model is as follows：
A kind of special tooling for the drilling of heavy truck back axle shell pieces, including two pieces of arcs being parallel to each other, described two
Block arc by positioned at secondly the connecting plate at end is fixed together, described arc lower section radian and rear axle housing to be processed
Piece top radian is consistent, and position is provided with several boring positioning blocks, described boring positioning block between two pieces of described arcs
Boring positioning hole is provided with, two sides contacted with arc on described boring positioning block are equipped with several screwed holes, described
Boring positioning block be connected with arc by the connecting hole on the arc of screwed hole, nut and setting, described connecting plate
Lower section is provided with the spacing edge-cut consistent with back axle shell pieces width to be processed.
Further, described connecting hole is waist hole structure, and resigning is provided with positioned at waist hole superstructure on described arc
Notch.
Further, several carrying handles are additionally provided between two pieces of described arcs.
Compared with prior art, implementation result of the present utility model is as follows for the utility model：
A kind of special tooling for the drilling of heavy truck back axle shell pieces described in the utility model, frock main body is mutually flat by two pieces
Capable arc is constituted, and arc lower section radian is consistent with back axle shell pieces top radian to be processed, using back axle to be processed
Positioning for shell pieces top radian, carries out secondary positioning, while being provided between two pieces of arcs by the spacing connecting plate of two sides
The boring positioning block of activity, positions convenient and swift, reduction cambered surface hole positioning difficulty, improves the effect of back axle shell pieces cambered surface hole
Rate.
