Abstract
The utility model provides an eccentric fixture is used in processing of super smart outer raceway of bearing eccentric strap grinding. It includes the dish -type fixture body, locating pin and clamp bolt, and the bearing eccentric raceway centre of a circle and dish -type fixture external footpath centre of a circle coincidence, bearing eccentric cover and the dish -type fixture body dress card rear bearing eccentric raceway centre of a circle and machine tool rotary center between coincidence are guaranteed with the dish -type fixture body through the locating pin through clamp bolt and dish -type fixture body coupling, the eccentric cover of bearing to the eccentric cover of bearing. The utility model discloses a positioning pin guarantees the centre of a circle position of eccentric raceway, utilizes the offset in the eccentric cover external diameter centre of a circle of location pinhole and bearing to offset the offset between the eccentric raceway centre of a circle and the machine tool rotary center, makes by finished surface axle center and rotation axis coincidence, realizes the high precision grinding to the eccentric raceway of process.
Description
Technical field
This utility model relates to grinding bearing rings Fixture Design, is specifically related to the outer raceway processing eccentric fixture of a kind of bearing eccentric hoop grinding superfinishing.
Background technology
The function of printer, is by printing oiling roller and the tight paper of fixing roll-in in parallel, rotarily drives paper by oiling roller and move, and by ink printing on paper, the gap between printing oiling roller and fixing roller is to determine according to the thickness compressing paper.The axle two ends of printing oiling roller are separately installed with capacity eccentric bearing, and the gap adjusted between printing oiling roller and fixing roller realizes by the offset adjusting this two sets capacity eccentric bearing.During printing oiling roller work, high speed rotating (rotating speed is at about 40000 revs/min), drives paper high speed to move and realizes high efficiency printing.Printing is by multiple printing oiling roller pipeline system operations, is respectively completed the chromaticity printing on same, and paper printing oiling roller on streamline during high-speed mobile must assure that mutual not skewed guarantee printing quality.Therefore, the running accuracy to the capacity eccentric bearing for adjusting printing oiling roller and fixing roller gap requires that reaching 4 grades of (eccentric raceways circularity 0.002mm), offset dimensional tolerances reaches 0.015mm.When grinding eccentric raceways, the orientation axis that is installed is the most concentric with processed axle surface axis, cannot use the routine mode that is installed that the raceway face processed carries out on bearing special purpose grinder grinding, need, by means of a kind of eccentric fixture, eccentric raceways surface to be carried out grinding.
Summary of the invention
The purpose of this utility model is that providing a kind of is capable of the outer raceway processing eccentric fixture of bearing eccentric hoop grinding superfinishing to eccentric working surface high-precision grinding processing.
The purpose of this utility model is achieved in that it includes dish-type fixture body, alignment pin and fishbolt, bearing eccentric bushing is connected with dish-type fixture body by fishbolt, by alignment pin, bearing eccentric bushing and dish-type fixture body ensure that the bearing eccentric raceways center of circle overlaps with the dish-type fixture body external diameter center of circle, the bearing eccentric bushing rear bearing eccentric raceways center of circle that is installed with dish-type fixture body overlaps between machine tool rotary center.
This utility model uses alignment pin to ensure the home position of eccentric raceways, the offset utilizing dowel hole and the bearing eccentric bushing external diameter center of circle offsets the offset between the eccentric raceways center of circle and machine tool rotary center, make surface to be machined axle center and rotation axis coincident, it is achieved the high-precision grinding to processed eccentric raceways.
This utility model is made up of dish-type fixture body, alignment pin, fishbolt, and bearing eccentric bushing ensure that eccentric accurate positioning with dish-type fixture body by alignment pin, and eccentric raceways home position and raceway precision after grinding are satisfied by product drawing requirement.
By alignment pin, bearing eccentric bushing ensures that the bearing eccentric raceways center of circle overlaps with the fixture body external diameter center of circle with fixture body, utilize bolt to be clamped with fixture body by bearing eccentric bushing, after being installed, overlap between the eccentric raceways center of circle with machine tool rotary center.During grinding, on the basis of fixture external diameter, bearing eccentric raceways is carried out grinding.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with Fig. 1, this utility model is further described:
In conjunction with Fig. 1, the present embodiment includes dish-type fixture body 1, alignment pin 4 and fishbolt 3, bearing eccentric bushing 2 is connected with dish-type fixture body 1 by fishbolt 3, by alignment pin 4, bearing eccentric bushing 2 ensures that the bearing eccentric raceways center of circle overlaps with the dish-type fixture body external diameter center of circle with dish-type fixture body 1, the bearing eccentric raceways center of circle overlaps between machine tool rotary center.
The grinder frock of the present embodiment, alignment pin is used to ensure the home position of eccentric raceways, the offset utilizing dowel hole and the bearing eccentric bushing external diameter center of circle offsets the offset between the eccentric raceways center of circle and machine tool rotary center, make surface to be machined axle center and rotation axis coincident, it is achieved the high-precision grinding to processed eccentric raceways.
