Handheld back holt punching machine

Abstract

The invention discloses a handheld back bolt punching machine. A drilling angle die machine rotates to drive a drill bit to rotate, a limiting knob is rotated, the distance between a limiting block atthe lower end of a limiting screw and a punching face is adjusted, and therefore the punching depth is adjusted. A drilling connecting rod handle is downwards pressed, the drill bits conducts punching, and a hole expanding motor is a speed reducing motor. An upper oblique cutting block is driven, the engagement depth of the upper oblique cutting block and a lower oblique cutting block determinesthe deflection range, and the deeper the engagement is, the smaller the deflection is. The deflection hole expanding technology is completed by adjusting the engagement depth of the upper oblique cutting block and the lower oblique cutting block, the limiting depth of an adjusting rod is adjusted by rotating an adjusting screw, and the adjusting screw is locked through a locking knob after adjustment is completed. A deflection connecting rod handle is downwards pressed so that the engagement depth of the upper oblique cutting block and the lower oblique cutting block can be reduced, the drillbit is driven to do deflection movement, and the hole expanding effect is achieved. The engagement depth of the upper oblique cutting block and the lower oblique cutting block is adjusted through thedeflection connecting rod handle, and therefore the function of controlling the hole expanding diameter is achieved.

Description

technical field [0001] The invention relates to the technical field of curtain wall boring, in particular to a hand-held back bolt punching machine. Background technique [0002] The back bolt dry hanging system can effectively fix various curtain wall panels. The hidden "internal wedge cutting" method is suitable for various interior and exterior decorations of buildings. It is a system composed of stainless steel back bolts, aluminum alloy connectors, and metal keels. With the development of social economy and the improvement of people's quality of life, higher requirements are put forward for the quality of living environment, which promotes the development of curtain wall decoration industry. With the widespread use of stone, ceramic panels and clay panels on curtain walls, higher requirements are put forward for the safety performance and construction technology of curtain walls. [0003] At present, when drilling the curtain wall, the existing punching machines common...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held back-bolt punching machine in order to solve the above problems, which solves the problem that the punching machines commonly used in the existing market have uneven punching accuracy when drilling holes on the curtain wall. Dimensions such as the depth of the hole and the size of the support hole are difficult to adjust and change. The roundness deviation of the punched hole is relatively large, and the shape of the punched hole is an oval hole, which poses a safety hazard.
