Abstract
The utility model discloses a tapered hole single key broaching device comprising a guiding sleeve and a positioning sleeve. A vertical plate hole of a broaching machine is connected with one end of the positioning sleeve and the other end of the positioning sleeve is provided with an oblique plane connected with the guiding sleeve. The guiding sleeve is provided with a positioning spindle nose which is matched with a tapered hole of a workpiece. Guide grooves capable of containing broaches are installed inside the guiding sleeve and the positioning sleeve. The tapered hole single key broaching device has the advantages that the workpiece can be directly fixed on the positioning sleeve without alignment and clamping; the tapered hole single key broaching device guarantees that a tapered hole generatrix of the workpiece is parallel to the track of a broach margin, and the degree of symmetry of the broach and the tapered hole centre line is directly ensured too; the depth ofthe broached key groove is guaranteed by the depth of the guide grooves and can be adjusted by padding of thin copper plates; and after the device is adjusted, the broaching process is only a process of the broaches being pulled through the guide grooves, therefore the device is simple in operation, steady in processing quality, high in processing efficiency and low in processing cost.
Description
Technical field
The utility model relates to keyway attachment, is specifically related to a kind of tapered hole singly-bound broacher.
Background technology
At present, adopting broaching layout processing singly-bound keyway, is the most frequently used processing method of standard machinery manufacture field, and it has, and production efficiency is high, crudy stable, simple operation and other advantages.
The normal wire cutting method that uses is processed singly-bound at present, but obviously has following shortcoming:
A, cutting processing efficient are too low, and the process-cycle is long, sometimes impact assembling;
B, processing charges are high, by market price 0.004/m
2, keyway expense of line cutting needs 15 yuan;
C, with line cutting processing keyway, all want location clamping behind the centering endoporus for every, then cut behind the threading, operate cumbersomely, non-cutting time is long, crudy is unstable, working (machining) efficiency is low;
D, company do not have linear cutting equipment, and external obilque line cuts singly-bound has increased freight and production cycle, has increased production cost.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of tapered hole singly-bound broacher being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of tapered hole singly-bound broacher, it comprises fairlead and positioning sleeve, one end of described positioning sleeve is connected with broaching machine riser hole, the other end has the inclined-plane, this inclined-plane is connected with fairlead, fairlead is provided with the location spindle nose that matches with the work piece tapered hole, is provided with the guiding groove that can hold broaching tool in described fairlead and the positioning sleeve.
Described fairlead and positioning sleeve are fastening by screw and alignment pin.
Described positioning sleeve and broaching machine riser hole are interference fits.
Described fairlead and workpiece to be machined are matched in clearance.
The utility model has solved following technical problem:
A, processed workpiece directly install on the positioning shaft sleeve and get final product, without centering and clamping;
B, guarantee that by this device the taper hole bus of workpiece is parallel with broaching tool land track, also directly guaranteed the symmetry of broaching tool and taper hole center line;
C, by the depth of gathering sill, guarantee by the degree of depth of broaching keyway, and can regulate by the cushioning sheet copper;
D, mix up this device after, the broaching process is the process that broaching tool is pulled through guiding groove, and is simple to operate, crudy is stable, working (machining) efficiency is high, processing charges is low, every processing charges is counted roughly 2.8 yuan/part.
Description of drawings
Fig. 1 is the utility model right view;
Fig. 2 is the longitudinal sectional view of Fig. 1;
1. fairleads wherein, 2. positioning sleeve, 3. soket head cap screw, 4. alignment pin, 5. broaching machine head of a bed riser, 6. workpiece to be machined, 7. broaching tool, 8. right tilted surface, 9. guiding groove, 10. location spindle nose.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the product of our company, the workpiece that two kinds of cone hole machine singly-bound keyways are arranged, when product just began Development and Production, the consumption of these two kinds of workpiece was few, total consumption is about 130 approximately per month, and we have adopted the line cutting mode to process the interior keyway of its taper hole.Afterwards along with the continuous increase of output, per month total consumption of these two kinds of workpiece has reached about 1000, if continue to use wire cutting method processing singly-bound, Shortcomings then, requirement for the production of adaptation company, we have designed and produced a kind of tapered hole singly-bound broacher, and it comprises fairlead 1 and positioning sleeve 2.Fairlead 1 and positioning sleeve 2 are fastening by soket head cap screw 3 and alignment pin 4.The left end of described positioning sleeve 2 is connected with broaching machine riser hole on the broaching machine head of a bed riser 5, be interference fits, right-hand member has right tilted surface 8, this right tilted surface 8 is connected with fairlead 1, fairlead 1 is provided with the location spindle nose 10 that is little matched in clearance with the work piece tapered hole, is provided with the guiding groove 9 that can hold broaching tool 7 in described fairlead 1 and the positioning sleeve 2.The gradient of right tilted surface 8 will guarantee that the taper hole bus of workpiece to be machined 6 is parallel with broaching tool 7 land tracks, has also directly guaranteed the symmetry of broaching tool 7 with the taper hole center line.
In designing and producing process, to guarantee that to fairlead 1 symmetry, width, the degree of depth of guiding groove 9 reaches the angle to the left side, to guarantee the degree of depth, width, relative center line and the symmetry of right tilted surface 8 and the angle of right side of guiding groove 9 to positioning sleeve 2.Positioning sleeve 2 attaches together with broaching machine riser hole employing H8/k7 transition joins, workpiece to be machined 6 adopts the little matched in clearance of H8/g7 with fairlead 1, broaching tool 7 adopts the F8/h8 matched in clearance with guiding groove 9, for improving the service life of this device, fairlead 1 and positioning sleeve 2 all adopt to grind behind the 20CrMnTi carburizing and quenching and form, and performance safety is reliable.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
