Description
Technical field
The utility model relates to a kind of Machining of Shaft-type Parts fixture, is specifically related to a kind of axial workpiece grinding cylindrical fixture, belongs to Machining Technology field.
Background technology
Axial workpiece is parts important in transmission system, and the mating surface (cylindrical) of axle and other Assembly of the parts has the requirement of shape and position, the general processing adopting following locate mode to realize axle mating surface (cylindrical):
1, two centre bore positioning and clamping are adopted:
Generally locate as roughing standard using important periphery, process centre bore, then with the centre bore at axle two ends for positioning accurate benchmark, the two ends adopting heart carrier fixed axis class more; This kind of installation way can be avoided producing catcher mark, but to need two ends all the axial workpiece of grinding cannot realize clamped one time and complete grinding;
2, outer round surface positioning and clamping is used:
For the axial workpiece that hollow shaft or short and small axle etc. can not be located with centre bore, the periphery location of available axle, by clamp periphery transmitting torque; The universal fixturings such as general employing scroll chuck, chuck, or various high-precision self-centering special fixture, as first-class in elastic clip; This kind of installation way easily produces catcher mark on axle class periphery, affects part outer surface quality.
Therefore, research one accomplishes unifying datum, datum coincidence, acted as reference mutual as far as possible, and realizes the axle class special jig for grinding that once mounting processes multiple surface and become problem demanding prompt solution in the industry.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provides a kind of easy to use, and clamped one time can process the axle class grinding fixture on multiple surface.
Realizing the technical scheme that the utility model object adopts is, a kind of axial workpiece grinding cylindrical fixture, at least comprise the driving terminal pad for being arranged on axial workpiece end and be fixed on the driving handle driven on terminal pad periphery perpendicular to axial workpiece axis, an end face of described driving terminal pad is provided with more than 2 for connecting the alignment pin of axial workpiece, each alignment pin, perpendicular to driving the end face of terminal pad and being distributed on end face, drives the center of terminal pad to offer guide through hole vertically.
Described alignment pin is provided with 2, and 2 alignment pin symmetries are fixed on an end face of driving terminal pad.
Drive an end face of terminal pad to be provided with more than 2 blind holes distributed in pairs, blind hole is uniform on the end face driving terminal pad, and alignment pin is arranged in corresponding blind hole according to the size of axial workpiece, and alignment pin is connected with driving the blind threaded of terminal pad.
Described guide through hole is bellmouth.
As shown from the above technical solution, the alignment pin on terminal pad is driven to coordinate with the locating hole of axial workpiece end face, axial workpiece is connected with driving terminal pad by alignment pin, the driving lever of machine tool headstock is near the driving handle driving terminal pad, lathe is top to be against in the centre bore of axial workpiece two ends through guide through hole, and driving lever promotes to drive and carries out grinding driving axial workpiece to rotate.
Axial workpiece grinding cylindrical fixture tool of the present utility model has the following advantages:
1, this clamp structure is simple, and convenient mounting and clamping, does not need centering, and clamping precision is high;
2, eliminate the heart carrier of existing axial workpiece two ends clamping, to needing the axial workpiece energy clamped one time of two ends all grinding to complete grinding, process simple and convenient, grinding efficiency is high;
3, because axial workpiece each shelves mating surface (cylindrical) clamped one time completes grinding, the axiality of the axial workpiece therefore processed can reach higher requirement;
4, can determine the installation site of two alignment pins according to the size of axial workpiece to be processed, therefore this fixture is applicable to the Cylindrical Grinding Processes of various sizes axial workpiece.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is illustrated in detail.
The axial workpiece grinding cylindrical fixture that the utility model provides, its structure as depicted in figs. 1 and 2, comprising driving terminal pad 1 for being arranged on axial workpiece end and being fixed on perpendicular to axial workpiece axis drives driving on terminal pad periphery 2, the bottom of handle is driven to be connected with driving the quarter turn face of terminal pad periphery, drive and the length of 2 can be pushed driving being as the criterion with driving lever, an end face of terminal pad is driven to be provided with 2 for connecting the alignment pin 3 of axial workpiece, each alignment pin is perpendicular to driving the end face of terminal pad and being symmetrically distributed on this end face, above-mentioned end face is provided with more than 2 blind holes 11 distributed in pairs, blind hole is uniform on above-mentioned end face, alignment pin is arranged in corresponding blind hole according to the size of axial workpiece, alignment pin is connected with driving the blind threaded of terminal pad, the center of terminal pad is driven to offer taper guide through hole 12 vertically.
During actual use, as shown in Figure 3, alignment pin 3 is arranged in corresponding blind hole according to the size of axial workpiece 6, driving terminal pad 1 is assemblied in the end face of axial workpiece 6 by alignment pin, lathe top 7 is through the guide through hole driving terminal pad, and top 7 aim at axial workpiece two ends centre bores positions clamping, to the driving of terminal pad 1 be driven 2 near the driving lever 4 of machine tool headstock 5, start lathe, promoted to drive 2 by driving lever 4, thus drive axial workpiece 6 rotation to carry out grinding.
