Description
Technical Field
The invention relates to the technical field of automobile part manufacturing, in particular to a tool for assisting in assembling a gear bolt of a main speed reducer of a differential.
Background
In a front-wheel drive transmission assembly product, a differential mechanism sub-assembly product needs to be assembled with main speed reduction teeth and then is fastened and fixed through bolt torsion. The assembly on the production line is carried out through equipment capable of automatically screwing. During equipment failure or when trial-manufacturing assembles the new product, need design the positioning frock, carry out differential mechanism bolt torsion and tighten fixedly.
The existing differential mechanism bolt torsion tightening tool comprises positioning reverse gear teeth at the left end and the right end of a base, when the differential mechanism bolt torsion tightening tool is used, a main speed reduction gear is clamped between the two positioning reverse gear teeth, bolt torsion tightening is carried out through the main speed reduction gear teeth fixedly positioning reverse gear teeth (a part of the tool is formed by the reverse gear teeth), as differential mechanism bolt tightening torque is large (100 N.m), positioning is carried out through the positioning reverse gear tooth surface, the gear surface has tooth surface scratch risks, the surface of a part gear is easy to be impacted, images can be caused to the thickness and the super-depth of the gear surface, and therefore the sound performance of a transmission assembly can be influenced. In addition, because the main speed reduction gear is a helical gear, a differential assembly for assembling the main speed reducer is positioned in a tool, when the bolt torque force is tightened, the differential can be fixed only by tightening a left bolt and a right bolt for fixing the reverse gear after the positioning reverse gear carefully aligns with the main speed reduction gear. The process has high requirement on the operating skills of the staff, long operating time and lower assembly efficiency.
Disclosure of Invention
The invention aims to solve the problem of providing a differential main reducer tooth bolt assembling tool so as to solve the problems that the assembling quality of a gear bolt of an existing differential main reducer is influenced and the assembling efficiency is low.
In order to solve the problems, the technical scheme of the invention is as follows: the differential main reducer tooth bolt assembling tool comprises a base, wherein two upright posts are vertically arranged at two ends of the base, a positioning block which is transversely arranged and extends towards the middle of the two upright posts is arranged in the middle of the two upright posts, a limiting groove for roughly limiting a bell mouth position of a differential shell is arranged on the positioning block, clamps are arranged at the tops of the two upright posts, and positioning hammers with horizontal positioning surfaces are clamped by the two clamps; the middle part of the upper surface of the base is provided with a circular positioning block for accurately positioning the bottom of the differential case, and the circular positioning block is provided with a positioning lug for accurately positioning a stop watch buckle positioning groove at the bottom of the differential case.
In the above technical solution, a more specific solution may be: the top of the upright post is connected with the clamp through a hexagon socket head cap screw.
Further: the positioning block penetrates through the upright post and is provided with a limiting block.
Further: the limiting block is connected with the upright post through a hexagon socket head cap screw.
Further: the positioning hammer longitudinally penetrates through the clamping arm of the clamp and is fastened by a bolt.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
the differential main reducer tooth bolt assembling tool adopts a positioning lug for accurately positioning a stop watch buckle positioning groove at the bottom of a differential shell so as to accurately fix a differential; positioning blocks on upright columns on two sides of a base are adopted, a limiting groove for roughly limiting a bell mouth position of a differential case is arranged on each positioning block, a plane where the bell mouth position of the differential case is located and a plane where a positioning groove of the differential case is located have a vertical relation, a blank surface of the bell mouth position is designed to be a rough positioning limiting block, and differential guiding positioning and rough positioning are carried out; the clamp on the upright post and the positioning hammer with the horizontal plane longitudinally clamp the main reducing gear, so that the main reducing gear is prevented from falling off, tightening and loosening when a differential bolt is tightened for torsion tightening, the assembly efficiency is greatly improved, and the assembly quality is not influenced; based on different product's two horn mouths of differential casing apart from difference and differential casing constant head tank place reference circle diameter and constant head tank size difference, design different thick location stopper and smart location seat and satisfy different motorcycle types and carry out trial-manufacturing assembly or production line equipment trouble during, production line temporary assembly.
