Description
Technical field
The utility model belongs to machinery processing apparatus, is specifically related to the high-precision boring device in the casing worm bearing hole of worm gear case.
Background technology
At present, the casing worm bearing hole of worm gear case processes at general boring machine, for processing first an end bearing hole, again 180 ° of work table rotations are proofreaied and correct machining hole after, processing other end dead eye; This processing method is owing to dead eye is processed at twice, so two hole coaxiality errors are larger, cause the casing that processes when assembling, can not guarantee product quality, the product that causes processing is constantly done over again, and product quality is not increased, and affects the delivery date of product.
Summary of the invention
The purpose of this utility model is: a kind of high-precision boring device is provided, first positive boring one end bearing hole reaches drawing requirement during use, anti-boring other end dead eye again, the assurance casing is finished the processing in worm bearing hole, two ends in clamped one time, this device rotates behind the Product Assembly flexibly in the situation that there is not numerical control device to solve key in the casing manufacture process, reduces noise, improve the quality of products, guarantee the delivery date of product.
Technical solution of the present utility model is: this boring device comprises base plate, wallboard, locating core, knife bar body, taper shank and copper sheathing float, on base plate, fix two wallboards by bolt and pin spacing distance, locating core is fixed on the base plate by soket head cap screw between two wallboards, the interior aperture holding screw axial restraint copper sheathing of wallboard, the endoporus penetration type of copper sheathing is installed the knife bar body, fix the taper shank that floats by knife bar coupling bar and straight pin on the knife bar body, by the screw spacing distance two floating boring tools are installed at the knife bar body, whole formation boring device.
Wherein, at wallboard force-feed oil cup is installed.
At first, hang on casing, the worm wheel aperture of casing is cooperated with the locating core cylindrical, the side positioning reference plane of proofreading and correct base plate compresses base plate, four blocks of vertical compression plates and four backing plates are fixed on casing on the base plate by studs and nut, the knife bar body passes casing, and centering worm bearing hole end surface makes locating core cylindrical center line equal casing Worm Bearing hole to worm bearing hole centre-to-centre spacing to knife bar body distance between center line; Then, the taper shank connection motor that floats, the positive and negative precession of the cutter relieving body of rod, thereby positive and negative boring worm bearing hole.
The utlity model has following advantage: 1, the casing boring device is simple in structure, and is easy to adjust, and locating core is fixed on the base plate by soket head cap screw, and the locating core cylindrical cooperates the location with the casing worm wheel aperture; 2, casing clamped one time, positive and negative boring worm bearing hole, the axiality in assurance bearings at both ends hole.3, be particularly useful for the large batch of casing processing of long span.
