Magnetic force frame for clamping electric drill or pneumatic drill

Abstract

A magnetic force frame for clamping an electric drill or a pneumatic drill comprises a frame body, a base, two guide rails, a connection cover plate, a lead screw, a holder, a switchable permanent magnet and two reinforced supports, wherein the L-shaped guide rails are arranged in pair, the lead screw is provided with rectangular threads, the holder comprises a transmission block and a clamping ring, the transmission block is provided with internal rectangular threads which are matched with the threads of the lead screw, the clamping ring is in a ring hoop structure, and the holder is meshed with the rectangular threads of the lead screw through the internal rectangular threads after being positioned. The invention has the advantages that: the magnetic force frame adopts the switchable strong permanent magnet, so the safety and stability of the electrical drill or the pneumatic drill during the punching, tapping and reaming processes can be ensured; the trapezoidal thread lead screw and cover plate-slide rail type transmission is adopted, the hole position precision and punching verticality during the punching, tapping and reaming processes can be ensured; and the magnetic force frame has a light volume, can clamp various electrical drills and pneumatic drills to punch, tap and ream, and the working efficiency is greatly improved.

Description

(1) Technical field [0001] The invention relates to a clamping tool for an electric drill or a pneumatic drill, in particular to a magnetic frame for clamping an electric drill or a pneumatic drill. (2) Background technology [0002] In the current rapidly developing industrial field, the production and manufacture of automobile molds, bridge construction, and square steel structures all involve drilling, tapping, and reaming. Commonly used tools are electric drills or pneumatic air drills. Due to the different workplaces and work content of using electric drills or pneumatic drills for drilling, tapping and reaming, the clamping requirements for electric drills or pneumatic drills are also different, which sometimes results in poor clamping of electric drills or pneumatic drills. complex. Especially in the drilling operation, sometimes the verticality of the hole is very high, and the clamping requirements of the electric drill or pneumatic drill are also stricter, otherw...
