Abstract
The utility model relates to a gear grinding fixture for a large double-helical gear shaft. The gear grinding fixture consists of a fixing base and an adjusting base sleeve; the adjusting base sleeve is arranged on the fixing base through the matching between a positioning groove of the adjusting base sleeve and a positioning boss on the fixing base. The adjusting base sleeve is provided with adjusting screws, and the perpendicularity of the gear shaft is adjusted by adjusting the adjusting screws; the fixing base is provided with locking screws, the coaxiality of the gear shaft is adjusted through the locking screws, and after the adjustment is finished, the locking screws are uniformly fastened to perform gear grinding processing.
Description
Technical field
The utility model relates to a kind of large-scale double helical tooth gear grinding tooling for gear shafts.
Background technology
The following several installation way of the general employing of existing gear grinding tooling:
(1) two top clamping; (2) the top clamping in one end chuck one end; (3) use cover for seat clamping.
Several clamping method bearing capacitys are little above, be only applicable to diameter less, length is short, and the gear shaft that weight is lighter, and be subject to the restriction of gear grinding machines pitch of centers, can not be applicable to large gear axle, bearing capacity requires very large, clamping requires solid and reliable, main equipment cutting force, and efficiency requires high requirement.
Summary of the invention
The utility model main purpose is: a kind of frock for large-scale double helical tooth gear shaft clamping location is provided.
The utility model is a kind of large-scale double helical tooth gear grinding tooling for gear shafts, and its innovative point is: described large-scale double helical tooth gear grinding tooling for gear shafts is made up of firm banking and adjustment cover for seat; One end of described firm banking is convex table top, and the other end is mounting flange face, and firm banking periphery is equipped with reinforcement gusset; Described adjustment cover for seat one end is detent face, and the other end has tapped through hole, inside has adjustment screw; The detent face of described adjustment cover for seat coordinates and is connected with the convex table top of firm banking.
On this basis: described adjustment screw is distributed in adjusts cover for seat end face, and quantity is 4 or 8.
On this basis: between described firm banking both ends of the surface, have tapped through hole, inside have lock-screw, screw top globulate.
On this basis: described lock-screw is two rows, be distributed between the upper and lower both ends of the surface of firm banking, lock-screw quantity is 8 or 16.
On this basis: described gusset is four, gusset is distributed between firm banking periphery both ends of the surface, has two through holes on every gusset.
The beneficial effects of the utility model are:
1. this tool structure is simple, easy to use, can pass through clamped one time, just can grinding double helical tooth axle two side gears of different rotation directions, the position error of having avoided repeated clamping to cause, has so just saved time of clamping, improve the productivity ratio of enterprise, also improved the qualification rate of product simultaneously.
2. this frock bearing capacity is strong, and clamping is firm, and this has just improved the quality of product, has avoided making product in process, occur deviation because clamping is unstable, causes unnecessary waste.
3. this frock range of work is wide, can be according to different spindle nose diameters, change adjust cover for seat just can, saved enterprise and made for different spindle nose diameters the production cost that different frocks are brought.
Below coordinate accompanying drawing to describe in detail.
Brief description of the drawings

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1: this gear grinding tooling, by adjusting cover for seat 1 and firm banking 2 forms, is adjusted in cover for seat 1 and is equipped with and adjusts screw A, and an end face of adjusting cover for seat 1 is detent; One end of firm banking 2 is mounting flange face, and the other end is positioning boss, and lock-screw B is housed on firm banking 2, and firm banking is with gusset C outward.
Adjust between the detent face of cover for seat 1 and the convex table top of firm banking 2 and just coincide, this fit structure is simple, is easy for installation and removal, and can realize difform large gear axle by changing different adjustment cover for seat, convenient and swift, save frock cost.
There is again the perpendicularity of carrying out exactly regulating tooth wheel shaft by adjusting screw A, when gear shaft has tilting, rotate and adjust screw A, gear shaft to which direction tilts, and just rotates the screw of that direction, until perpendicularity adjustment completes, this regulative mode is simple and practical, operate convenient, fast, the perpendicularity of control gear axle well, and then make the Product Precision of processing high; Carry out the axiality of regulating tooth wheel shaft by lock-screw B, the lock-screw B intensity adopting is high, and screw top is spherical, to surface of the work not damaged, operate convenient, fastly equally, clamping is solid and reliable, the cutting force bearing is large, can give full play to the cutting power of lathe, and working (machining) efficiency is high.
Because this frock is large-scale double helical tooth gear grinding tooling, what process is all heavier large gear, in order to strengthen frock intensity, facilitate frock to be in place smoothly, the special gusset C in firm banking 1 periphery, two through holes offering on gusset are can be in place smoothly in order to lift and finely tune frock.
As shown in Figure 2; By the shaft diameter size of gear, select to adjust the specification of cover for seat, be illustrated as two kinds of schematic diagrames of adjusting cover for seat.
This frock adopts clamped one time, can distinguish two side gears of the different rotation directions in grinding double helical tooth axle both sides, has guaranteed precision of grinding teeth.
