Abstract
The invention discloses a novel jig which comprises an eccentric cam, a cam shaft, a main piston, a bracket, adjusting screws, clamping arms, pivot pin shafts, precompression adjusting bolts, a transmission piston, a central support, concentrated butter and a tension spring. The central support is fixedly arranged at the center of the grooved bracket; through holes are symmetrically arranged on the two sides of the two ends of the central support along the width direction; the two clamping arms are respectively hinged on the two side faces of the bracket through the pivot pin shafts; the eccentric cam is hinged through the cam shaft on the upper side of the bracket which is arranged along the length direction of the central support; the main piston is installed in a hole at the end of the central support, which is close to the eccentric cam, and the transmission piston is installed in a hole at the width direction of the central support; the tension spring passes through the through holes arranged at the two sides of the central support; and the concentrated butter is injected from a middle hole along the length direction of the central support.
Description
Technical field
The present invention relates to a kind of jig, particularly a kind of novel lathe anchor clamps belong to the jig technical field.
Background technology
In the machine-building process; Run into various types of machine components through regular meeting,, just must the blank of workpiece or the semi-finished product of workpiece be fixed on the workbench of lathe in order to make these parts; Have that to install and fix workpiece efficient low; Clamping force is little, influences labor productivity, reduces the defective of product quality easily.
Summary of the invention
The objective of the invention is to: a kind of novel lathe anchor clamps are provided, overcome and have in the existing mechanical processing that to install and fix workpiece efficient low, clamping force is little, influences labor productivity, reduces the defective of product quality easily.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of novel lathe anchor clamps; 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; Centre at troffer installs and fixes center bearing bracket; Both sides at the width two ends of center bearing bracket have through hole symmetrically, in the support two sides with each hinged two clamp arm of fulcrum pin axle; 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, and force-transmitting piston is installed in the hole of center bearing bracket width; Extension spring is passed from the through hole of center bearing bracket both sides, in the interstitial hole of center bearing bracket length direction, injects dense butter.
Beneficial effect: the present invention is because after adopting such scheme, when clamping work pieces, not only efficient is higher, and simultaneously, clamping force is bigger, and it is low to overcome the above-mentioned existing workpiece efficient that installs and fixes effectively, influences labor productivity, reduces the defective of product quality easily.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is a structure chart of the present invention.
Shown in the figure: 1, eccentric cam; 2, camshaft; 3, main piston; 4, support; 5, adjustment screw; 6, clamp arm; 7, fulcrum pin axle; 8, precommpression adjustment screw; 9, force-transmitting piston; 10, center bearing bracket; 11, dense butter; 12, extension spring.
The specific embodiment
Install and fix center bearing bracket (1) in the centre of troffer (4); Both sides at the width two ends of center bearing bracket (10) have through hole symmetrically, in support (4) two sides with each hinged two clamp arm (6) of fulcrum pin axle (7); Above the support (4) of center bearing bracket (10) length direction; With the hinged eccentric cam of camshaft (2) (1), main piston (3) is installed in the hole of center bearing bracket (10) near eccentric cam (2) one ends, and force-transmitting piston (9) is installed in the hole of center bearing bracket (10) width; Extension spring (12) is passed from the through hole of center bearing bracket (10) both sides, in the interstitial hole of center bearing bracket (10) length direction, injects dense butter (11).
