A metal door and window lock hole grinding device

Abstract

The invention relates to the technical field of metal processing, and discloses a metal door and window lock hole grinding device, which specifically includes: a fixed column, one end side of the fixed column is fixedly connected with a fixed frame, the inner wall of the fixed frame is slidably connected with a telescopic plate, and the telescopic plate One side extends to the outside of the fixed frame and is fixedly connected with an arc-shaped grinding device; an extruding plate, which is arranged on the top of the arc-shaped grinding device, and the extruding plate is provided with two vertical and inclined sections; extruding and shrinking The extrusion shrinkage sleeve is set on the fixed column and is threadedly connected with the fixed column. The shape of the extrusion shrinkage tube is adapted to the shape of the extruded plate; the control device is arranged at the bottom of the fixed column and It is fixedly connected with a fixed column, and the invention relates to the technical field of metal processing. The metal door and window lockhole grinding device is convenient to adapt to lockholes of different diameters, does not need to replace the grinding head, is convenient to use, and can be replaced with a drill bit, does not need special driving equipment, is small in size, and is easy to carry and use.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a metal door and window lock hole grinding device. Background technique [0002] Metal processing, referred to as metalworking, refers to the production activities that humans process metal elements or materials with metal characteristics mainly composed of metal elements. It is a process technology that processes metal materials into articles, parts, and components, including large parts such as bridges and ships, and even small components of engines, jewelry, and watches. It is widely used in science, industry, artwork, Handicrafts and other different fields. The lockholes on metal doors and windows usually need to be polished on the inner wall of the lockhole after the machining is completed, so as to avoid the burrs on the inner wall from affecting the fit of the connectors. However, the currently used grinding device has poor adaptability. It is inconvenient to re...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a metal door and window lock hole grinding device, which solves the problem that the inner wall of the lock hole usually needs to be polished after the lock hole on the metal door and window is processed, so as to avoid the burrs on the inner wall from affecting the fit of the connectors. , but the currently used grinding device is poor in adaptability. When encountering a keyhole with a different aperture, it is necessary to replace the corresponding grinding block, which is inconvenient to use.
