Abstract

The invention relates to a machine tool fixture for clamping cylindrical workpiece tightly, wherein a central bracket is fixedly arranged at the central part of a grooved bracket; two clamping arms are respectively articulated on two lateral surfaces of the bracket by a pivot pin shaft; every two clamping arms are symmetric to each other; an eccentric cam is articulated on the bracket in the length direction of the central bracket by using a camshaft; a main piston is installed in a hole at one end of the central bracket close to the eccentric cam; a force transmission piston is installed in a hole in the width direction of the central bracket; a tension spring passes through via holes at two sides of the central bracket; the two ends of the tension spring are respectively fixed to the bottoms of the clamping arms; an upper adjusting screw is disposed above each of the clamping arms so that the axis of the adjusting screw and the axis of the force transmission piston are located on the same axis; concentrated grease is injected from an intermediate hole in the length direction of the central bracket; and an oil injection hole is sealed tightly by using a pre-compressed adjusting screw.

Description

The powerful jig that clamps of a kind of column workpiece
Technical field
The present invention relates to a kind of jig, the powerful jig that clamps of particularly a kind of column workpiece belongs to the jig technical field.
Background technology
In the machine-building process, the machine components through regular meeting runs into the cylinder class in order to make these parts, just must be fixed on the blank of workpiece or the semi-finished product of workpiece on the workbench of lathe.At present, the main method that the column workpiece blank is fixed on the platen is to adopt the way of v block and T type bolt, does not have the special jig that installs and fixes the powerful clamping of column workpiece.This employing v block and T type bolt install and fix the way of column workpiece, have that to install and fix workpiece efficient low, and clamping force is little, influences labor productivity, reduces the scarce limit of product quality easily.
Summary of the invention
The objective of the invention is to: provide a kind of column workpiece the powerful jig that clamps, overcome in the existing mechanical processing owing to there is not the powerful existing above-mentioned scarce limit of jig that clamps of special column workpiece.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the powerful jig that clamps of a kind of column workpiece; It is made up of eccentric cam, camshaft, main piston, support, adjustment screw, clamp arm, fulcrum pin axle, precommpression adjustment screw, force-transmitting piston, center bearing bracket, dense butter, extension spring, and the powerful jig that clamps of column workpiece has a troffer, is mounted with a center bearing bracket in the centre of troffer; In the support two sides with each hinged two clamp arm of fulcrum pin axle; Symmetrical between per two clamp arms, above the support of center bearing bracket length direction, with the hinged eccentric cam of camshaft; Main piston is installed in the hole of center bearing bracket near eccentric cam one end; Force-transmitting piston is installed in the hole of center bearing bracket width, and extension spring is passed from the through hole of center bearing bracket both sides, and the two ends of extension spring are separately fixed at the bottom of clamp arm; Install adjustment screw above the clamp arm at each; The axis of adjustment screw and the axis of force-transmitting piston are on the same axis, in the interstitial hole of center bearing bracket length direction, inject dense butter, and oil filler point is shut with the precommpression adjustment screw.
Beneficial effect: the present invention is because after adopting such scheme, when clamp cylinders shape workpiece, not only efficient is higher; Simultaneously; Clamping force is bigger, can overcome effectively that to adopt v block and T type bolt to install and fix the existing workpiece efficient that installs and fixes of mode of column workpiece low, and clamping force is little; Influence labor productivity, reduce the scarce limit of product quality easily.
