Abstract
The utility model discloses a clamp device of tube cutting machine driven by coaxal pressure cylinder, which is a simple structure, convenient maintaining and safe clamp device for tube cutting machine driven by air-driving or hydraulic transmission to cold cut steel tubes. The device adopts a hollow reciprocating pressure cylinder which is concentric with the hollow main axle to impel the central sleeve arranged in the hollow main axle to dive the conic disk which is arranged in the chuck to do axial movement; the conic disk installed on the hollow main axle rotates together with the main axle and the claw is made to do radial motion by means of the conical surface of the conic disk, thus, the rapidly clamping and loosening of the workpiece can be realized during a host works.
Description
The invention belongs to a kind of lathe clamping device, be particularly useful for doing the clamping device of cold cut steel pipe pipe cutting machine.
At present, the kind of drive of cold cut steel pipe pipe cutting machine clamping device has pneumatic gearing, three kinds of hydraulic drive and machine driving.The Japan spy reaches the 6UTH pipe cutting machine clamping device employing hydraulic drive that lathe Co., Ltd. produces, and it can clamp or unclamp workpiece rapidly by the awl dish in hydraulic pressure declutch lever and the boosting lever promotion chuck under the main frame rotation situation.This device shortcoming is a complex structure, and consumable accessory is many, and Chang Yin changes the part stopping production in the production, and maintenance is also very difficult simultaneously.The G-001 pipe cutting machine clamping device that Guangdong machine tool plant produces adopts spring force to clamp pneumatic unclamping.It is simple in structure that this equipment is cut clamping device than the 6UTH Pipe Cutting, but because running the time can not be given the chuck air feed, must treat can press from both sides after chuck comes to a complete stop, loose workpiece.
Task of the present invention is to provide a kind of simple in structure, easy to maintenance, and can utilize pneumatic or hydraulic drive to realize clamping and unclamping the cold cut steel pipe pipe cutting machine clamping device of workpiece rapidly under the main frame working order.
Operation principle of the present invention is: cylinder or hydraulic cylinder are made hollow reciprocating type pressure cylinder, and make pressure cylinder and hollow spindle concentric, chuck then is installed on the hollow spindle.Just the awl dish that directly promotes when the hollow piston of pressure cylinder axially moves in the intermediate sleeve drive chuck in the hollow spindle also axially moves; Meanwhile, the awl dish makes claw do radial motion again in company with main axis rotation by its conical surface.So just, the awl dish of having realized utilizing pressure cylinder directly to promote chuck under the main frame working order clamps workpiece or unclamps.
Below, in conjunction with the accompanying drawings principle of the present invention is done a detailed description.
Fig. 1 is a fundamental diagram of the present invention.
With reference to Fig. 1, hollow reciprocating type pressure cylinder (3) is installed on the cylinder seat (4) on the headstock, and concentric with hollow spindle (5), cylinder body is fixed.The hollow piston (1) of hollow reciprocating type pressure cylinder (3) links to each other by the left end of rolling bearing (2) intermediate sleeve (6) interior with being installed in hollow spindle (5), intermediate sleeve (6) is under the effect of piston (1), when axially moving, the awl dish (8) that drives in the chuck (7) that links to each other with its right-hand member also axially moves.Chuck (7) then is installed on the hollow spindle (6) and main shaft (6) together rotates, thereby makes its awl dish (8) make claw (9) do radial motion by the conical surface.So just, realized under the main frame working order, utilizing pressure cylinder directly to promote awl dish in the chuck, workpiece is clamped or unclamped.
The present invention is used on the cold cut steel pipe Pneumatic pipe cutting machine clamping device, proves through practical application, and it has not only realized pressing from both sides rapidly in main frame running situation, loose workpiece, and use, easy to maintenance. In addition, because claw does not stretch out the chuck end face, can not block during rotation, bump the tube head of cutting-out, thus safe and reliable.
Claims (3)
1, a kind of cold cut steel pipe pipe cutting machine clamping device of mainly being made up of main shaft, pressure cylinder, intermediate sleeve and chuck, the pressure cylinder that it is characterized in that this pipe cutting machine clamping device is hollow reciprocating type pressure cylinder, and concentric with hollow spindle.
2, cold cut steel pipe pipe cutting machine clamping device according to claim 1 is characterized in that the awl dish in this pipe cutting machine clamping device chuck is to be axially moved by the intermediate sleeve drive that pressure cylinder directly promotes in the hollow spindle.
3, cold cut steel pipe pipe cutting machine clamping device according to claim 1 and 2, the pressure cylinder that it is characterized in that this pipe cutting machine clamping device can be a cylinder, also can be hydraulic cylinder.
