Abstract
The utility model discloses a cylindrical roller V-shaped grinding face fixture. V-shaped grooves used for the placement of rollers are provided at the end of the V-shaped block (6), a support plate (5) is provided at the tip of each V-shaped groove, pressing mechanisms including a pressing board (1), a locking nut (2), a guiding pin (3), a clamping bolt (4) and a handle (8) are provided on the supporting plate, one end of the clamping bolt is connected to the pressing board screw thread through the supporting board by the locking nut, the other end of the clamping bolt is connected to the handle, the guiding pin is provided between the supporting board and the pressing board. Using V-shaped fixture, the utility model achieves processing cylindrical roller face on the plane grinder, replaced the traditional methods to reduce the labor intensity of the workers and shortened the processing cycle. More than one roller can be grinded and the efficiency of production is greatly improved. The cylindrical roller face cycle run out is ensured, the quality of bearing products is improved. When the accuracy of plan machine tool is stable, the roller face cycle run out percent of pass can be 100%.
Description
Technical field
The utility model belongs to the fixture for grinding machine technical field, and what relate generally to is a kind of Cylindrical roller mill base V-Clamp.
Background technology
Cylinder roller bearing is because of it can bear bigger radial load, characteristics are widely used in the large-scale tumblers such as machine tool chief axis, rolling machinery applicable to running up etc.Can the cylindrical roller basal plane circle of the cylinder roller bearing quality of beating guarantee, will directly influence the rotating accuracy and the service life of bearing.
Traditional cylindrical roller basal plane grinds processing to carry out on the 3A64 lathe, and its processing mode is that roller is placed on the V-block, realizes what mill was processed with the hand rotary roller, once only can grind a roller.Owing to be difficult to make the rotating speed of roller even, thereby be difficult to guarantee the crudy that roller datum end face circle that grinding is come out is beated with the hand rotary roller.Often need touch repeatedly and cut, repair rate reaches more than 50%.These class bearings such as special picture 6729/658,6729/748,6727950Y, roller weight all in 7kg, diameter and length all more than 100, very painstaking with the hand rotary roller, labour intensity is big especially.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of Cylindrical roller mill base V-Clamp.Utilize these anchor clamps can be on the lathe of plane processing column roller basal plane, not only guaranteed the quality that cylindrical roller basal plane circle is beated, and alleviated working strength of workers, improved production efficiency.
For achieving the above object, the technical scheme that the utility model is taked: be provided with the V-type groove that is used to place roller at the two ends of V-block, end at each V-type groove is provided with gripper shoe, gripper shoe is provided with the hold-down mechanism that is made of hold-down bolt, pressing plate, locking nut, pilot pin and handle, one end of hold-down bolt passes gripper shoe and is connected with the pressing plate rib-loop through locking nut, the other end of hold-down bolt is connected with handle, and an end of pilot pin passes gripper shoe fixedlys connected with pressing plate.
The utility model is reasonable in design, and is simple in structure.It utilizes the V-type anchor clamps to be implemented in processing column roller basal plane on the surface grinding machine, has replaced traditional processing method, has reduced working strength of workers, has shortened the process-cycle.Because of surface grinding machine can be placed a plurality of V-type anchor clamps, therefore once can grind a plurality of rollers, improved production efficiency greatly.Guaranteed that cylindrical roller basal plane circle beats, improved the bearing products quality.Because two V-type faces in the V-type anchor clamps are perpendicular to end face, cylindrical roller is positioned in the V-type anchor clamps like this, just guaranteed during clamping that the cylindrical roller axis is vertical with end face, circle that just can easier assurance cylindrical roller basal plane with respect to hand rotates is beated, the method grinding can also be avoided by wheel grinding hidden danger in one's hands except that reducing labor strength.Under the stable situation of plane machine tool accuracy, the roller datum end face circle qualification rate of beating can reach 100%.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1. pressing plate 2. locking nuts 3. pilot pins 4. hold-down bolts 5. gripper shoe 6.V type pieces 7. screws 8. handles 9. rollers.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: present embodiment is to be provided with the V-type groove that is used to place roller at the two ends of V-block 6, is provided with gripper shoe 5 in the end of each V-type groove, and this gripper shoe 5 is fixedlyed connected with V-block 6 by screw 7.Gripper shoe 5 is provided with the hold-down mechanism that is made of pressing plate 1, locking nut 2, pilot pin 3, hold-down bolt 4 and handle 8, one end of hold-down bolt 4 passes gripper shoe 5 and is connected with pressing plate 1 rib-loop by locking nut 2, promptly be provided with connecting hole on pressing plate 1, this connecting hole is a blind hole.The other end of hold-down bolt is connected with handle 8.Drive pressing plate when preventing that hold-down bolt from rotating and rotate, be provided with pilot pin 3 between gripper shoe 5 and pressing plate 1, an end of this pilot pin 3 is fixedlyed connected with gripper shoe 5, and the other end is fixedlyed connected with pressing plate 1.Present embodiment is placed on roller 9 in the V-type groove of V-block 6 in use, and turning handle 8 drives locking nut 2 by hold-down bolt 4 and promotes pressing plate 1 with cylindrical roller 9 clampings, is placed on the surface grinding machine and can grinds basal plane.Finish the anti-phase turning handle in mill processing back, locking nut drives pressing plate, makes cylindrical roller loosening, cylindrical roller can be taken out.
