Auxiliary fixture for drilling multi-size mechanical hardware

Abstract

The invention discloses an auxiliary fixture for drilling multi-size mechanical hardware. The auxiliary fixture comprises a drilling platform, two clamping mechanisms are arranged on the two sides ofthe middle of the upper end of the drilling platform, the two clamping mechanisms are symmetrically arranged, each clamping mechanism comprises an arc-shaped central plate, the two ends of each arc-shaped central plate are provided with rectangular notches, arc-shaped clamping plates are movably inserted into the rectangular notches, U-shaped steel plates are welded to the inner sides of verticalplates of L-shaped steel plates, installation circular blocks are fixed to the middles of the inner sides of the U-shaped steel plates, and the ends, away from a rotating disc, of screw rods are fixedly connected with rotating blocks. According to the auxiliary fixture for drilling multi-size mechanical hardware, the angles of the arc-shaped clamping plates can be freely adjusted according to different diameters of different hardware, the fixing effect on hardware with different sizes is achieved, the variability and the adjustability are high, the application range is wide, fixing is more stable, the fixing effect is good, the practicability is strong, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an auxiliary clamp for drilling holes in multi-size mechanical hardware. Background technique [0002] Hardware, also known as "hardware", refers to five metals: gold, silver, copper, iron, and tin. After manual processing, it can be made into knives, swords and other works of art or metal devices. Hardware in modern society is more extensive, such as hardware tools, hardware tools, etc. Parts, daily hardware, construction hardware and security supplies, etc. Hardware is widely used in the field of machinery. For the processing of mechanical hardware, punching operations are often required. In the prior art, circular hardware is punched During operation, because of its smooth surface, if the fixing effect is not good, it is easy to cause the hardware to slide, shift and rotate, thus causing errors in the punching position; in the prior art, when punching circular hardware, Howe...

[0002] Hardware, also known as "hardware", refers to five metals: gold, silver, copper, iron, and tin. After manual processing, it can be made into knives, swords and other works of art or metal devices. Hardware in modern society is more extensive, such as hardware tools, hardware tools, etc. Parts, daily hardware, construction hardware and security supplies, etc. Hardware is widely used in the field of machinery. For the processing of mechanical hardware, punching operations are often required. In the prior art, circular hardware is punched During operation, because of its smooth surface, if the fixing effect is not good, it is easy to cause the hardware to slide, shift and rotate, thus causing errors in the punching position; in the prior art, when punching circular hardware, However, most of these fixtures can only fix the hardware of the same model size, the variability and adjustability are poor, and the scope of application is small; therefore, we propose an auxiliary fixture for drilling multi-size mechanical hardware
