Abstract
The utility model discloses a clamp for a grinding gear with a spherical end surface, which is characterized in that the clamp comprises a flange and a clamp head which are fixedly connected. The flange and the clamp head have the same rotating axial line; positioning pin shafts are arranged on the outer surface of the clamp head, and the axial lines of the positioning pin shafts pass through and are vertical to the rotating axial lines; the axial lines of all the positioning pin shafts are positioned on a same plane; and a wokpiece quick clamping device is also arranged on the clamp head. The clamp can simultaneously and quickly clamp and fix a plurality of gears with spherical end surfaces, facilitates the precise processing of processing equipment to the spherical end surfaces of the gears, realizes high efficiency, and improves the dimension precision and the surface smoothness of the spherical end surfaces of the gears.
Description
[technical field]
The utility model relates to a kind of anchor clamps, particularly be a kind of anchor clamps that are used for the grinding worm spherical end surface.
[background technology]
The spherical end surface gear is the gear that an a kind of side end face is a spherical arc, mainly being installed on vehicle transmission, drive axle and automobile axle etc. locates, it and spherical pad are used, if both no-floats, can reduce the wearing and tearing of spherical pad, increase the service life of automobile component, can reduce greatly simultaneously owing to often change maintenance time and the expense that spherical pad brought.Thus, an important technology index of spherical end surface gear is its sphere dimensional accuracy and fineness, and the processing of existing spherical end surface gear generally is to adopt turning fine finishining, can not guarantee sphere precision and fineness well, and workpiece is independent clamping, processing separately, efficient is low, the cost height.
[summary of the invention]
Problem in view of present known technology existence, the technical problems to be solved in the utility model is the anchor clamps that are to provide a kind of grinding worm spherical end surface, these anchor clamps can carry out quick-clamping and fixing to a plurality of gears with spherical end surface simultaneously, make things convenient for the fine finishining of process equipment to the gear spherical end surface, the efficient height, the dimensional accuracy and the surface smoothness of raising gear spherical end surface.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of anchor clamps of grinding worm spherical end surface, it is characterized in that: described anchor clamps comprise fixedly connected flange and chuck, flange has identical rotation with chuck, the outer surface of chuck is equipped with alignment pin, the axis of alignment pin by and perpendicular to rotation, the axis of all alignment pin is positioned at same plane, also is provided with the workpiece fast fixture on the described chuck.Described clamping device comprises gland, and the screw that screw rod that the gland lower end has and described alignment pin axle head are offered matches, and the diameter of gland upper surface is greater than the workpiece diameter of bore, and the upper surface of described gland also is provided with in order to turn the well of gland rotation.
Anchor clamps of the present utility model, be equipped with a plurality of alignment pin (according to the specification size of spherical end surface gear at the chuck outer surface, the number of alignment pin is set) with the spherical end surface gear quantity that can put, each alignment pin can effectively be located a workpiece to be machined, clamp fast then, by spheric grinding machine a plurality of workpieces to be machined are carried out grinding simultaneously, thus, grinding fine finishining when these anchor clamps have been realized a plurality of workpiece, the efficient height, the while has also guaranteed the dimensional accuracy and the surface smoothness of gear spherical end surface.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the part drawing of spherical end surface gear
Fig. 2 is a structural representation of the present utility model
Fig. 3 is the A-A view of Fig. 2
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, the upper surface of spherical end surface gear 1 is a spherical arc 2, and the lower surface is the plane, this plane and spherical end surface bore axis normal.
With reference to accompanying drawing 2,3, the anchor clamps of this grinding worm spherical end surface, comprise fixedly connected flange 3 and chuck 8, flange has identical rotation with chuck, chuck 8 has columniform outer surface, on chuck 8 columniform outer surfaces, be equipped with six pin-and-holes, in each pin-and-hole, be provided with alignment pin 6, the diameter of bore of the diameter of alignment pin 6 and gear 1 matches, alignment pin 6 is fixedlyed connected with chuck 8 by pin 10, the axis of alignment pin 6 by and perpendicular to rotation, the axis of all alignment pin is positioned at same plane, on chuck 8 cylindrical outer surfaces, also be provided with cushion block 7, cushion block 7 is enclosed within outside the alignment pin 6, and the curved surface that cushion block 7 lower surfaces have and chuck 8 cylindrical outer surfaces are fitted, and cushion block 7 upper surfaces are the planes with alignment pin 6 axis normal, in order to the planar end of Support Gear 1, the thickness of cushion block is determined according to the size and the gear thickness of gear spherical arc; The last axle head of alignment pin 6 offers screw, alignment pin is by this screw gland 4 that has been threaded, gland 4 upper surface downsides have an inclined-plane 5, this inclined-plane 5 matches with gear 1 interior Hole chamfering, just in time can be pressed against on the chamfering of gear 1 endoporus, the upper surface of gland 4 is processed with interior hex slot 9, just can turn gland 4 rotations with inner hexagon spanner like this.
When grinding spherical end surface gear, the flange of anchor clamps is connected (this moment, gland screwed off from the alignment pin axle head) with the ring flange of process equipment (spheric grinding machine) with bolting, the spherical end surface bore of need grinding is enclosed within on the alignment pin, the planar end of gear leans against on the cushion block down, gland precession alignment pin then, with inner hexagon spanner gland is screwed, this moment, gland just can compress gear, very efficient and convenient, at this moment, the ring flange of spheric grinding machine rotates, and drives the anchor clamps rotation, the form grinding emery wheel feed of spheric grinding machine is simultaneously carried out grinding to the spherical end surface that carries out of gear.
