Abstract
The utility model provides a device for fixing a tap so as to process the tap, and in particular provides a tap notch grinding sleeve type positioning device. The tap notch grinding sleeve type positioning device comprises a fixed sleeve and a movable sleeve; the fixed sleeve is arranged on a fixing frame; an edge end and a handle end of a component are respectively inserted into the fixed sleeve and the movable sleeve; a cooling pipe is arranged at the end part of the fixed sleeve; and a grinding wheel is arranged above the fixed sleeve. According to the tap notch grinding sleeve type positioning device, the positioning mode of a notch in processing is changed, and the outer circle of a tap blank is clamped by the sleeves, so that the stiffness in grinding is greatly improved, and the powerful grinding process for grinding the notch can be smoothly and easily carried out; the stiffness is improved, so that the cooling effect is enhanced, the tap notch can be processed at one time, no burns and cracks are generated, the working efficiency is increased by more than five times, and the quality of a product can be ensured as well.
Description
Technical field
The utility model is a kind of device, the particularly telescopic positioner of a kind of tap groove grinding groove of processing for fixing screw tap to screw tap.
Background technology
The working portion of screw tap all is designed with groove vertically, generally is referred to as chip pocket, and its effect is the control chip-flowing and holds bits, forms simultaneously cutting edge and anterior angle.Groove comprises straight trough groove and spiral grooves, and groove is the important structure on the screw tap, and groove processing is the important procedure of screw tap processing.
The groove processing of screw tap, the general method that all adopts grinding is during the grinding groove, screw tap to be located, existing positioner is seen Fig. 1, is top 2 with shank top 1 and blade, withstands on respectively workpiece 3(screw tap blank) on the centre bore at two ends, blade top 2 the top be provided with emery wheel 4 and cooling tube 5, this positioner adds the man-hour workpiece and easily shakes, and the crudy of groove is poor, the burn situation is serious, and seminess is many.
Summary of the invention
The purpose of this utility model is to cause the poor defective of workpiece wobbling groove crudy in order to overcome existing top positioner, invents a kind ofly to be clamped in screw tap shank and blade and can to add the heavy-duty grinding rigidity and make the stably telescopic positioner of tap groove grinding groove of workpiece.
The purpose of this utility model realizes as follows: the telescopic positioner of described tap groove grinding groove, comprise fixed muffle and quill, fixed muffle is located on the fixed mount, the sword end of workpiece and pommel are inserted in respectively in fixed muffle and the quill, the end of fixed muffle is provided with cooling tube, and the top of fixed muffle is provided with emery wheel.
Good effect of the present utility model is as follows: the utility model has changed the positioning form in the groove processing, uses sleeve clamping screw tap idiosome cylindrical, greatly strengthens the rigidity of grinding, and the high-rate grinding process that the mill groove is adopted becomes smoothly and be light; Because rigidity is strengthened, and has strengthened cooling effect, groove of screw tap can process at one time, and without burn, flawless, improves work efficiency more than 5 times, and product quality is guaranteed simultaneously.

Fig. 2 is the utility model structure chart
Among the figure: top 3 workpiece of top 2 blades of 1 shank
4 emery wheels, 5 cooling tubes, 6 fixed muffles
7 quills, 8 fixed mounts
The specific embodiment
As shown in Figure 2, the telescopic positioner of described tap groove grinding groove, comprise fixed muffle 6 and quill 7, fixed muffle 6 is located on the fixed mount 8, the sword end of workpiece 3 and pommel are inserted in respectively in fixed muffle 6 and the quill 7, the end of fixed muffle 6 is provided with cooling tube 5, and the top of fixed muffle 6 is provided with emery wheel 4.
During work, fixed muffle is fixed, and opening is arranged on the fixed muffle, is convenient to the wheel grinding groove.Bear grinding force by fixed muffle during the mill groove, compare with top positioner, change whole cylindrical contact into by 2 contacts, its contact area is large, has larger grinding rigidity, simultaneously be provided with cooling tube in the fixed muffle end, cooling fluid can enter in the sleeve from cooling tube, directly wash away the iron filings in the groove of milled just, because grinding speed is with 80 meter per second High Rotation Speeds, powerful spinning force is with cooling fluid wheel grinding ejection in the sleeve, the pressure of cooling fluid is brought up in 10 Palestine and Israels by 2 original bar, strengthen cooling effect, made cooling more abundant, solved the groove grinding burn, the difficult problem that the groove crackle is many.And during top location, because the High Rotation Speed of emery wheel, cooling fluid spills with the revolving force of emery wheel, can't arrive the grinding position, and cooling effect is very poor, and processing problems is a lot.Therefore, advantage of the present utility model is very significant.
Claims (1)
1. telescopic positioner of tap groove grinding groove, it is characterized in that: comprise fixed muffle and quill, fixed muffle is located on the fixed mount, the sword end of workpiece and pommel are inserted in respectively in fixed muffle and the quill, the end of fixed muffle is provided with cooling tube, and the top of fixed muffle is provided with emery wheel.
