Abstract

The utility model discloses a clamping clamp on a vertical lathe. The clamping clamp comprises clamping jaw bases and clamping jaws. The clamping clamp is characterized in that the clamping jaws comprise swing arms, rotating blocks, vertical rotating bushings, horizontal rotating bushings and clamp blocks; the swing arms are located on the upper parts of the clamping jaw bases by locating pins; the sides of the rotating blocks are connected at the two ends of the swing arms by the vertical rotating bushings; and the upper and lower sides of the rotating blocks are connected with the clamp blocks by the horizontal rotating bushings. The clamping clamp has the following beneficial effects that the clamping jaws are rotatable structures, and when the workpiece with a conical surface is clamped, the clamp blocks can automatically rotate to the required angles around the vertical rotating bushings and the horizontal rotating bushings under the gravity action of the workpiece, thus being suitable for clamping various workpieces with conical surfaces and dispensing with manual adjustment.

Description

The vertical lathe clamping device

Technical field

The utility model relates to a kind of vertical lathe clamping device.

Background technology

Original vertical lathe claw clamping area is for facing directly, and when the workpiece of the clamping band conical surface, the claw clamping area is contact workpiece fully; The not phenomenon of clamping of workpieces can appear pressing from both sides; Need claw be processed into the conical surface consistent with workpiece can clamping work pieces, and this need be the different claw of workpiece customization of various sizes, and the versatility of claw is poor; Change frequently, processing is inconvenient.

Summary of the invention

The purpose of the utility model is to provide a kind of versatility of claw good, can clamp the workpiece of various sizes and the clamping device on the vertical lathe easy to process automatically.

The technical scheme that the utility model adopts is: a kind of vertical lathe clamping device; Comprise master jaw, claw; It is characterized in that: said claw by swing arm, spill spin block, vertical rotary liner, horizontally rotate lining and fixture block is formed; Said swing arm is positioned at master jaw top by alignment pin, and the side of spill spin block is connected the swing arm two ends through vertical rotary liner, the spill spin block upper and lower surface through horizontally rotate lining and fixture block be linked together.

Between the side of said spill spin block and the swing arm alignment pin is housed.

Fine-tuning housing screw is installed on the said fixture block.

The claw of the utility model is rotatable structure; When clamping the workpiece of the band conical surface, under the gravity effect of workpiece, fixture block can rotate to needed angle automatically around vertical rotary liner, horizontal vertical lining; The workpiece that is suitable for the various band taperings of clamping does not need manual adjustment.

Among the figure, the 1st, workbench, the 2nd, master jaw, the 3rd, alignment pin, the 4th, fixture block, the 5th, horizontally rotate lining, the 6th, swing arm, the 7th, housing screw, the 8th, alignment pin, the 9th, vertical rotary liner, the 10th, spill spin block.

The specific embodiment

Below in conjunction with accompanying drawing and practical implementation instance the utility model is done further to set forth.

Can know from Fig. 1, Fig. 2, Fig. 3; The utility model is designed to rotatable structure with claw; Master jaw 2 tops are by alignment pin 3 location swing arms 6, and swing arm can horizontally rotate on master jaw, and spill spin block 10 is installed at the swing arm two ends; Vertical rotary liner 9 with swing arm and spill spin block be linked together, spill spin block can be done the rotation of vertical direction around vertical rotary liner; Alignment pin 8 is housed between the side of spill spin block and the swing arm, prevents that the relative motion of spill spin block and swing arm is excessive; The spill spin block upper and lower surface through horizontally rotate lining 5 and fixture block 4 be linked together, fixture block can be done the horizontal direction rotation around horizontally rotating lining, and housing screw is installed on the fixture block, can finely tune where necessary.

Method for using: when clamping the workpiece of the band conical surface, under the gravity effect of workpiece, fixture block can rotate to needed angle automatically around vertical rotary liner, horizontal vertical lining, is suitable for the workpiece of the various band taperings of clamping, does not need manual adjustment.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
