The utility model has the advantages workpiece clamping and rotating and adjustable rotating speed of the workpieces.
Description
Technical field
The utility model relates to the clamping device on the lathe, particularly a kind of band saw machine clamping device.
Background technology
At present, the clamping device that band saw machine is provided with is made up of two fixed calipers that can clamp mutually and moving caliper and a clamping cylinder, the push rod of this clamping cylinder is connected with moving caliper, by the clamping cylinder effect, moving caliper and fixed caliper can fasten workpiece clamp on the workbench of sawing machine to carry out sawing.In actual production, many workpiece need carry out centre annular groove or two ends anchor ring sawing processing, but the workpiece because the above-mentioned clamping device of prior art can only be fixedly clamped can not make workpiece rotate, and makes sawing machine to carry out centre annular groove or the processing of termination anchor ring to workpiece.
Summary of the invention
The purpose of this utility model provides a kind of band saw machine clamping device.It can clamping work pieces and workpiece is rotated.
The technical solution of the utility model is:
A kind of band saw machine clamping device comprises a clamping cylinder, and this clamping cylinder is installed on the cnetre cradle, the push rod left end of this clamping cylinder from cnetre cradle the corresponding hole activity stretch out and be connected with movable thimble; Electric rotating machine is connected the speed changer left end, and fixedly thimble is fixed on the speed changer right-hand member axle, and with movable top coaxial needle line; Fixedly the thimble right side is provided with pin; Be equipped with installing hole on speed changer base and the cnetre cradle base plate, and its two bottom surface is fixed with the guide runner of coaxial line respectively.
Described speed changer can be friction type stepless speed changer.
Described movable thimble right-hand member can be Outer Taper, and the push rod left end of clamping cylinder is provided with internal taper hole, and the Outer Taper of movable thimble right-hand member is plugged in the internal taper hole of push rod left end.
The utility model has been owing to adopted the thimble clamping mode at two ends, and an end is provided with electric rotating machine and speed changer, and the other end is provided with clamping cylinder and movable thimble.Therefore, clamping device described in the utility model has clamping work pieces and workpiece is rotated and advantage such as the workpiece velocity of rotation is adjustable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-electric rotating machine, 2-speed changer, 3-be thimble, 4-pin, the movable thimble of 5-, 6-cnetre cradle, 7-clamping cylinder, 8-push rod, 9-cnetre cradle base plate, 10-guide runner, 11-lathe bed, 12-speed changer base fixedly.
The specific embodiment
A kind of band saw machine clamping device comprises a clamping cylinder 7, and described clamping cylinder 7 is installed on the cnetre cradle 6, push rod 8 left ends of this clamping cylinder from cnetre cradle 6 the corresponding hole activity stretch out, and be connected with movable thimble 5; Electric rotating machine 1 is connected speed changer 2 left ends, and fixedly thimble 3 is fixed on the speed changer 2 right-hand member axles, and with movable thimble 5 coaxial lines; Fixedly thimble 3 right sides are provided with pin 4; Be equipped with installing hole on speed changer base 12 and the cnetre cradle base plate 9, and its two bottom surface is fixed with the guide runner 10 of coaxial line respectively.
Described speed changer 2 is a friction type stepless speed changer, makes that the workpiece velocity of rotation is adjustable, with the corresponding relation between coupling workpiece rotational frequency and the saw blade linear speed.
Described movable thimble 5 right-hand members are Outer Taper, and push rod 8 left ends of clamping cylinder 7 are provided with the internal taper hole that cooperates with movable thimble, and movable top cushion is connected in the internal taper hole of push rod left end.
The movable thimble that uses on described movable thimble 5 structures and the general lathe is identical, is made up of movable conehead, bearing and thimble rod, and movable conehead turns.Respectively be provided with four vertical installation through holes on described speed changer base and the movable top punch block base plate.
During application, the guide runner 10 in speed changer base 12 and the movable top punch block base plate 9 is placed gathering sill corresponding above sawing machine 11 workbench.By placing the installing hole that is respectively equipped with on T-shaped screw rod and speed changer base and the movable top punch block base plate on the corresponding chute of workbench to be connected, friction type stepless speed changer and cnetre cradle can be separately fixed on the workbench of sawing machine.Workpiece is fixedly clamped by the two ends thimble, and interacting with pin 4 on fixing thimble 3 right sides by putting movement folder general on the machine tool on the workpiece of fixing thimble 3 one ends, guarantees that workpiece and speed changer 2 right-hand member axles rotate synchronously.
The utility model can clamping work pieces and workpiece is independently rotated, and can regulate the workpiece velocity of rotation by friction type stepless speed changer.
