Abstract
The invention discloses a hobbing and positioning sleeve of a gear-worm gear combined shaft, which comprises a body, wherein a mounting hole is arranged in the body, the inner diameter of the mounting hole is greater than the diameter of an addendum circle of a gear on the gear-worm gear combined shaft, the width value of the body is equal to a numerical value obtained after a distance value between the center line of the gear teeth of a worm gear and the fixed position of a shaft head is subtracted from one half of the tooth width value of the worm gear, a positioning structure which enables the center line of the mounting hole to be superposed with the axis of the gear-worm gear combined shaft is also arranged on the body, and the horizontal movement of the body is limited by the worm gear on the gear-worm gear combined shaft and a clamping head of a machine tool. The invention has simple structure and convenient manufacture, determines the distance between the center line of the gear teeth of the worm gear and the fixed position of the shaft head by transformation, fixes the gear-worm gear combined shaft quickly and accurately and enhances the production efficiency and the product quality.
Description
Technical field
The present invention relates to worm-wheel shaft gear hobbing auxiliary locator, the positioning sleeve that particularly a kind of gear-worm gear built-up shaft uses when the worm gear gear hobbing.
Background technology
In that being carried out gear hobbing, the worm gear on the gear-worm gear built-up shaft adds man-hour, the gear-worm gear built-up shaft clamps spindle nose by machine tool chuck and fixes, require worm gear gear teeth center corresponding with the hobboing cutter axis, therefore by accurately determining the fixed position of spindle nose, make worm gear gear teeth center line corresponding with the hobboing cutter axis, but owing to also have gear or other ladder axis bodies between spindle nose that machine tool chuck clamps and the worm gear, this makes the distance between worm gear gear teeth center line and the spindle nose fixed position be difficult to measure accurately, the worm gear gear teeth that process like this are likely and depart from gear teeth center line, also just can not satisfy worm and gear transmission requirement, seriously may scrap.
Summary of the invention
Problem to be solved by this invention just provides a kind of simple in structure, easily manufactured hobbing and positioning sleeve of gear-worm gear combined shaft, determine distance between worm gear gear teeth center line and the spindle nose fixed position by conversion, fix gear-worm gear built-up shaft, improve production efficiency and product quality fast again exactly.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of hobbing and positioning sleeve of gear-worm gear combined shaft, it is characterized in that: comprise body, in body, be provided with installing hole, the tip diameter that the internal diameter of described installing hole cogs greater than the gear-worm gear built-up shaft, the width value of described body equals the numerical value after the face width value that distance value between worm gear gear teeth center line and the spindle nose fixed position deducts half, also be provided with the location structure that makes installing hole center line and the dead in line of gear-worm gear built-up shaft on body, described body moves by worm gear on the gear-worm gear built-up shaft and machine tool chuck limit levels.
Further, described location structure comprises the capping that is arranged on body and the contacted end of machine tool chuck, described capping is provided with the locating hole that cooperates with the spindle nose and the shaft shoulder of gear-worm gear built-up shaft, the center line of described locating hole and the central lines of installing hole.
After adopting technique scheme, the present invention has following advantage: simple in structure, easily manufactured, determine distance between worm gear gear teeth center line and the spindle nose fixed position to fix gear-worm gear built-up shaft, improve production efficiency and product quality fast again exactly by conversion.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the cutaway view of an embodiment of the present invention;
Fig. 2 is the structural representation under user mode embodiment illustrated in fig. 1.
The specific embodiment
The structural representation of an embodiment of the present invention shown in Fig. 1 to 2, a kind of hobbing and positioning sleeve of gear-worm gear combined shaft, comprise body 1, body 1 moves by worm gear on the gear-worm gear built-up shaft 2 21 and machine tool chuck 3 limit levels, one end face of body 1 is against on the side of worm gear 21 on the gear-worm gear built-up shaft 2, the other end of body 1 contacts with machine tool chuck 3, in body, be provided with installing hole 11, the internal diameter of installing hole 11 is greater than cog 22 tip diameter of gear-worm gear built-up shaft 2, the width value of body 1 equals the numerical value after worm gear 21 facewidth values that distance value between worm gear gear teeth center line 211 and the spindle nose fixed position 231 deducts half, body 1 is provided with capping 12 with machine tool chuck 3 contacted ends, capping is provided with the locating hole 13 that cooperates with the spindle nose 23 and the shaft shoulder 24 of gear-worm gear built-up shaft, the central lines of the center line of locating hole 13 and installing hole 11 makes installing hole 11 center lines and 2 deads in line of gear-worm gear built-up shaft by locating hole 13.
The use principle of the foregoing description is: the present invention is enclosed within on the gear-worm gear built-up shaft to be processed, the its right end face and the worm gear side of body are offseted, to have gear-worm gear built-up shaft clamping of the present invention again in machine tool chuck, the lateral surface of machine tool chuck and the left end face of body are offseted, so just determined the fixed position of gear-worm gear built-up shaft spindle nose fast, thereby the distance between worm gear gear teeth center line and the spindle nose fixed position is met the demands, also just make worm gear gear teeth center line corresponding with the hobboing cutter axis.
The lateral surface cross section of body can be circular or square among the present invention, the present invention is simple in structure, easily manufactured, determine distance between worm gear gear teeth center line and the spindle nose fixed position to fix gear-worm gear built-up shaft, improve production efficiency and product quality fast again exactly by conversion.
Except that above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
