Abstract
The utility model relates to a key slot broaching guide bush which comprises a workpiece positioning shaft, a guide bush positioning shaft, a flange and a cutter spacing groove, wherein the central shafts of the workpiece positioning shaft, the flange and the guide bush positioning shaft are coincident and are connected into a whole according to the sequence, the cutter spacing groove is formed on the workpiece positioning shaft, and is further embedded inside the flange and the guide bush positioning shaft, the height of the cutter spacing groove is lower than that of the flange and that of the guide bush positioning shaft, the flange has a closed shape, and the height of the cutter spacing groove is lower than that of the semicircle of the flange. By changing the position of the cutter spacing groove, the utility model ensures that the flange is in a closed state so that the stress in the broaching guide bush is minimized, which guarantees the accuracy of the broaching guide bush in the broaching process, and improves the quality of the processed workpiece.
Description
(1), technical field
The utility model relates to a kind of keyway broaching guide pin bushing.
(2), background technology
Broaching is that keyway is processed widely used technology, has the efficient height, the advantage of stable accuracy, but if to reach high accuracy mainly by the decision of broaching guide pin bushing precision.The broaching guide pin bushing generally adopts mould steel to carry out Quenching Treatment because cutting force and the frictional force that will bear are all very high, line cutting behind correct grinding.The broaching guide pin bushing structure that adopts is made up of workpiece locating shaft, guide pin bushing locating shaft, flange, cutter spacing groove at present, the cutter spacing groove is stuck in workpiece locating shaft, guide pin bushing locating shaft, flange side, form the breach groove, this structure is subjected to internal stress influence after having the line cutting, be easy to generate distortion, the precision of influence broaching guide pin bushing finally influences the processing work quality.
(3), utility model content
The technical problem that the utility model solves provides the keyway broaching guide pin bushing that a kind of reduction is subjected to internal stress, improves precision in the broaching process.
A kind of keyway broaching guide pin bushing, comprise workpiece locating shaft, guide pin bushing locating shaft, flange, cutter spacing groove, workpiece locating shaft, flange overlap and are connected to each other in proper order according to this formation one with the central shaft of guide pin bushing locating shaft, the cutter spacing groove is opened on the workpiece locating shaft, and described cutter spacing groove also is embedded in flange and the guide pin bushing locating shaft.
Preferably, the height of described cutter spacing groove is lower than the flange height.
Preferably, the height of described cutter spacing groove is lower than guide pin bushing locating shaft height.
Preferably, described flange becomes closed form.
Preferably, the height of described cutter spacing groove is lower than flange semicircle height.
The beneficial effects of the utility model are:
The utility model makes flange become closed form by changing the position of cutter spacing groove, makes the broaching guide pin bushing be subjected to internal stress to drop to minimum, the precision of guide pin bushing in broaching processing and manufacturing process of guaranteeing to broach, the quality of raising processing work.
(4), description of drawings
Accompanying drawing 1 is the front view of the described keyway broaching guide pin bushing of specific embodiment.
Accompanying drawing 2 is cutaway views of the described keyway broaching guide pin bushing of specific embodiment.
(5), the specific embodiment
Below in conjunction with embodiment is described the utility model is further described, but protection domain of the present utility model is not limited thereto.
With reference to Fig. 1 or 2, a kind of keyway broaching guide pin bushing, comprise workpiece locating shaft 1, guide pin bushing locating shaft 2, flange 3, cutter spacing groove 4, workpiece locating shaft 1, flange 3 overlaps and is connected to each other in proper order according to this formation one with the central shaft of guide pin bushing locating shaft 2, cutter spacing groove 4 is opened in workpiece locating shaft 1, described cutter spacing groove 4 is embedded in flange 3 and the guide pin bushing locating shaft 2, the height of described cutter spacing groove 4 is lower than flange 3 height, the height of described cutter spacing groove 4 is lower than guide pin bushing locating shaft 2 height, 3 one-tenth closed forms of described flange, the height of described cutter spacing groove 4 are lower than flange 3 semicircle height.
The space of when the broaching guide pin bushing carries out the line cutting, having calculated the broaching tool need of work, the guide pin bushing opening part of will broaching leaves part and does not process, and such structure has the effect of eliminating broaching guide pin bushing internal stress, improves the precision in the broaching process.
Claims (5)
1, a kind of keyway broaching guide pin bushing, comprise workpiece locating shaft, guide pin bushing locating shaft, flange, cutter spacing groove, workpiece locating shaft, flange overlap and are connected to each other in proper order according to this formation one with the central shaft of guide pin bushing locating shaft, the cutter spacing groove is opened on the workpiece locating shaft, it is characterized in that described cutter spacing groove also is embedded in flange and the guide pin bushing locating shaft.
2, keyway broaching guide pin bushing according to claim 1 is characterized in that the height of described cutter spacing groove is lower than the flange height.
3, keyway broaching guide pin bushing according to claim 1 is characterized in that the height of described cutter spacing groove is lower than guide pin bushing locating shaft height.
