A kind of irregular bearing special purpose grinder

Technical field:

The present invention relates to the grinding machine equipment technical field, more specifically to a kind of special purpose grinder of processing irregular bearing.

Background technology:

Existing Oscillating lever bearing processing inner ring can only machining bearing be that the outer ring is the Oscillating lever bearing that is just adding fork above the circle; Can't process the outer ring is non-Oscillating lever bearing and the oscillating bearing that just adds fork above the circle; Such as the outer ring is that the Oscillating lever bearing that adds fork above the ellipse can't be processed, and also is not fit to the grinding machine equipment of this irregular bearing processing, simultaneously; The pay-off of existing Oscillating lever bearing is also unreasonable, needs manual work material loading constantly.

Summary of the invention:

The object of the invention is exactly the deficiency to prior art; And a kind of irregular bearing special purpose grinder is provided, it can process the outer ring is non-ly just to add the Oscillating lever bearing of fork and the inner ring of oscillating bearing above the circle, simultaneously; Need not manual work material loading constantly, solved the deficiency of prior art.

Technological solution of the present invention is following:

A kind of irregular bearing special purpose grinder; Comprise grinding main frame, main axis rotation mechanism, frame and blanking road, the blanking road is fixed on the frame, and the casing upper fixed of main axis rotation mechanism has discharging frame and hydraulic cylinder; Be fixed with work piece holder on the main shaft of main axis rotation mechanism; The grinding main frame is fixed on the planker of frame, and the emery wheel of grinding main frame is over against the centre bore of the end cap of work piece holder, and slideway is fixed on the casing of main axis rotation mechanism;

Be fixed with pushing block on the push rod of hydraulic cylinder, the pushing block sleeve is below the blowing bucket of discharging frame, and the charging aperture of slideway is over against pushing block, and the feed opening of slideway is over against the breach of work piece holder; The blanking road is over against work piece holder.

Said slideway is made up of main stem, side plate and baffle plate, and main stem and baffle plate are fixed on the casing of main axis rotation mechanism, and side plate is fixed on the main stem both sides, and baffle plate contacts with side plate, and baffle plate is over against main stem; Baffle plate, side plate one end and main stem one end constitute feed opening, and the side plate other end and the main stem other end constitute charging aperture.

Said work piece holder structure does, shell is connected on the main shaft through bolt, and end cap is connected on the shell through bolt, is inserted with cavity in the shell, and chamber outer wall is inserted with briquetting, and briquetting is being pressed cavity; Cavity one end is inserted with the ring-type briquetting, the other end is fixed with the catch bar that is provided with in the main shaft; Spring and pushing block sleeve are in catch bar, and pushing block is pressed against on the main shaft, and spring one end is put forth effort on pushing block, the other end is put forth effort on briquetting; Form breach on the shell, the workpiece sleeve is in breach, and cavity is pressed against on the workpiece, and the holding of ring-type briquetting is on workpiece, and workpiece is pressed against on the end cap.

Be fixed with material-storing box on the frame, material-storing box is over against the feed opening in blanking road.

Beneficial effect of the present invention is:

1, it through the push rod promotion of hydraulic cylinder, falls into the work piece holder breach with workpiece from slideway through workpiece is put on the discharging frame, processes, and reduces the artificial inconvenience of material loading constantly, reduces the labour.

2, its ring-type briquetting holding of being inserted with through cavity one end on workpiece with the center of fixation workpiece; And be pressed against on the side surface of workpiece through cavity and locate; Make that can process the outer ring is the non-inner ring that just adds the Oscillating lever bearing of fork above the circle, has solved the deficiency of prior art.
