Further, it is provided with concave station in the front end of spindle coupling disc, being provided with the flange of installation corresponding with concave station on transition disc, be connected by the first screw is fixing between spindle coupling disc with transition disc, the flange connector of transition disc end big with spring chuck is connected by the second screw is fixing.
Beneficial effect:
Use this utility model, it is only necessary to selecting satisfactory spring chuck, clamping workpiece is easy to operate rapidly, can greatly improve the work efficiency of bearing ring processing, reduce production cost.
With detailed description of the invention this utility model done the most concrete detailed description below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, cylinder, 2, cylinder end piece, 3, hollow spindle, 4, spindle coupling disc, 5, transition disc, 6, spring chuck, 7, blind rivet, 8, bearing ring, the 9, second screw, the 10, first screw, 11, main spindle box body, 12, cylinder lever connecting rod.
Detailed description of the invention
As it can be seen, the clamping device of a kind of engine lathe processing bearing ring, including main spindle box body 11 and the hollow spindle 3 that is rotatably located on main spindle box body 11, the front end of hollow spindle 3 is provided with spindle coupling disc 4.
Connect in spindle coupling disc 4 front end and have transition disc 5, it is provided with spring chuck 6 in transition disc 5 front end, spring chuck 6 is in hollow round table shape, the big end of spring chuck is connected by flange connector is fixing with transition disc 4, small end is provided with the cylindric lordosis for spring bearing lasso 8, and the excircle of cylindric lordosis is for the installation that matches with the endoporus of bearing ring 8.
Being convexly equipped with conical central hole before cylindric, conical central hole is pre-large post-small, and the centrage of conical central hole overlaps with the centrage of hollow spindle 3 setting.
Being provided with blind rivet 7 in conical central hole, blind rivet 7 includes the head of taper and shaft-like pulling portion, and the head of blind rivet 7 matches with conical central hole installation, and the pulling portion of blind rivet 7 puts in hollow spindle 3 backward；Be provided with cylinder 1 in the rear end of hollow spindle 3, the cylinder body of cylinder 1 is fixing with hollow spindle 3 to be connected, and the piston rod external part of cylinder 1 puts in hollow spindle 3 and is connected by a cylinder lever connecting rod 12 is fixing with the pulling portion of blind rivet 7.
Specifically, concave station can be set in the front end of spindle coupling disc 4, transition disc 5 arranges the flange of installation corresponding with concave station, be connected by the first screw 10 is fixing between spindle coupling disc 4 with transition disc 5.The flange connector that transition disc 5 is held greatly with spring chuck 6 is connected by the second screw 9 is fixing.
When this utility model uses, the bearing ring that will process is sleeved on the cylindric lordosis of spring chuck 6, cylinder 1 action, and piston extension bar drives blind rivet 7 to be moved rearwards by by cylinder lever connecting rod 10, so that spring chuck 6 clamp shaft bearing ring 8, then bearing ring 8 is processed.
According to said structure, when hollow spindle 3 rotates under the driving of driving means, connected spindle coupling disc 4, transition disc 6 collet 6, bearing ring (workpiece) 8, blind rivet 7, cylinder lever connecting rod 12 and cylinder 1 all rotate therewith.
After bearing ring 8 completion of processing, cylinder 1 action again, piston extension bar moves forward, and spring chuck 6 unclamps bearing ring 8.Thus realize the taking-up of bearing ring, to have reached the purpose of bearing ring processing.
When needing the bearing ring processing different model, it is only necessary to change suitable spring chuck 6.
Front end as herein described refers to hollow spindle 3 and stretches out main spindle box one end towards topping machanism, and accordingly, the other end of hollow spindle 3 is rear end.
