Alloy apparatus adjustable in clamping angle

Abstract

The invention relates to a clamping apparatus for machining and an alloy apparatus adjustable in clamping angle. The alloy apparatus adjustable in clamping angle comprise a left supporting crank arm,a right supporting crank arm, a left clamping device, a right clamping device and a hydraulic driving device; and the two ends of the hydraulic driving device are provided with the piston rod end headof a first piston and the piston rod end head of a second piston correspondingly in a stretching manner. According to the improvement, the right clamping device and the left clamping device are in mirror symmetry, and the left supporting crank arm and the right supporting crank arm are in mirror symmetry; an adjusting hand wheel disk is adopted for driving a position adjusting nut to move forwards and backwards on an adjusting screw rod; by means of linkage of a first connection rod and a second connection rod, a work included angle can be formed between a first clamping plate and a second clamping plate around an included angle shaft pin, a cylinder body is clamped, and the stress structure is improved; and up-down free swinging and rotating around a screw rod sleeve shaft pin can also be achieved, an object on a bevel is effectively clamped, functions are comprehensive, and the alloy apparatus adjustable in clamping angle is practical and convenient; and the clamping faces of the first clamping plate and the second clamping plate are each plated with a layer of hard chromium alloy, and abrasion resistance and durability are better.

Description

[0001] Technical field The present invention relates to a machining clamping instrument, especially an alloy instrument with adjustable clamping angle. Background technique

[0002] When metal workpieces are processed, vises are generally used to fix the workpieces, but vises can only be used to fix regular types of workpieces. When processing workpieces with irregular shapes, the existing clamping equipment has the following problems: One is that it cannot be firmly clamped, resulting in slow processing speed and low work efficiency; the second is that even if the workpiece is barely fixed before cutting, the workpiece is prone to loosening during actual operation.

[0003] Flat nose pliers are clamping instruments used to clamp parts, and are necessary accessories for machine tools such as machining centers, milling machines and drilling machines. Commonly used flat-nose pliers jaws are fixed, but the disadvantages are: for parts with irregular shapes, it is usually single-c...
