Abstract
A group blocking clamp for flatly grinding a bearing central spindle special for air spinning comprises a frame type clamp main body, a pressing plate is arranged in the frame type clamp main body, a screw hole is arranged in one end surface of the frame type clamp main body, and a clamping screw rod is connected with the outer side of the pressing plate through the screw hole. Sliding chutes are arranged on the inner sides of two longitudinal plates of the frame type clamp main body, and sliding rods matched with the sliding chutes are arranged on the two sides of the pressing plate. According to the group blocking clamp for flatly grinding the bearing central spindle special for air spinning, tens of central spindles are arranged in a clamp body by adopting the frame type clamp main body and are ground simultaneously, so that the work efficiency of a grinding machine is improved, and the processing cost is lowered. The length dimension tolerance of a processed workpiece is 0.05mm, the end face run-out amount is 0.03mm, and the process requirement is ensured.
Description
Technical field
The utility model relates to a kind of bearing processing apparatus, be specially the processing of a kind of air spinning special bearing grinding machine special-purpose crowd's clip tool.
Background technology
At present in bearing professional production enterprise; As needing processing capacity in bearing mandrel year up to hundreds thousand of; Because bearing mandrel both ends of the surface precision and length precision are all had relatively high expectations, after hardening, can only carry out clamping processing with part of the little scroll chuck of high accuracy; Production efficiency is extremely low, and production cost is also very high.
Summary of the invention
The utility model has designed a kind of air spinning special bearing mandrel plain grinding crowd clip tool to the problem that exists on the above-mentioned prior art, has solved the problem of poor efficiency when the grinding of bearing core axial end at present.
A kind of air spinning special bearing mandrel plain grinding crowd clip tool comprises a frame jig main body, it is characterized in that in the frame jig main body, pressing plate being arranged, and at an end face of frame jig main body screw is arranged, and clamping screw links to each other with the outside of pressing plate through screw.
Described air spinning special bearing mandrel plain grinding crowd clip tool is characterized in that there is sliding tray two vertical plate inboards of frame jig main body, and there is the slide bar with the sliding tray coupling both sides of said pressing plate.
The air spinning special bearing mandrel plain grinding crowd clip tool of the utility model adopts a frame jig main body will reach the dozens of mandrel and places in the clamp body, carries out grinding simultaneously, has improved the operating efficiency of grinding machine, has reduced processing cost.Workpiece to be machined length dimension tolerance reaches 0.05mm, and end face run-out amount 0.03mm has guaranteed technological requirement.
Description of drawings
Fig. 1 is the anchor clamps front views.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1-frame jig main body, 2-workpiece, 3-pressing plate, 4-clamping screw, 5-slide bar, 6-sliding tray.
The specific embodiment
Shown in the accompanying drawing 1-2; The air spinning special bearing mandrel plain grinding crowd clip tool of the utility model; Comprise that a cross sectional shape that is made up of four faces is the frame jig main body 1 of rectangle, a screw is arranged, clamping screw 4 is arranged in the screw in the central authorities of an end face of jig main body.Jig main body inner face one side has the pressing plate 3 of an activity, and the outside of this pressing plate 3 is connected with clamping screw 4.In order to guarantee that pressing plate 3 smoothly moves, be shaped on sliding tray 6 in jig main body two vertical plate inboards, on the both sides of pressing plate 3 slide bar 5 is arranged, during installation, slide bar 5 is placed in the sliding tray 6.And then be connected with screw rod 4.
Operation sequence, the first step are cleaned grinding machine magnetic work table top, each surface of frame anchor clamps and workpiece to be machined surface, and second step was positioned over clamp body the appropriate location of Grinder bench; The workpiece of cleaning 2 basal planes also are loaded on shown position in the frame anchor clamps downwards a part; Slowly clamp gently after waiting to install, knock the workpiece upper surface with "painted-face" character in opera then, its each and every one and magnetic platform surface are close to; Fastening more at last it, table top carries out grinding after giving magnetic.The 3rd step blew off workpiece 2 and chucking surface after waiting to have ground the upper surface, and turnover fixture after the degaussing is cleaned work top again; Unclamp clamping screw; Fall framework and return again with above-mentioned method and knock, can grind second after fastening, keep its length tolerance and end face run-out amount.
