Abstract

The utility model discloses an exchange brushless angle mill casing, including first casing and second casing, first casing front end is monolithic structure to at the inside motor accommodation space that sets up of first casing front end, set up in first casing rear end through the screw fixation behind second casing and the first casing lock, form the portion of holding at the whole middle part of casing after second casing is fixed with first casing, at the inside auxiliary electrical apparatus accommodation space that sets up in the whole rear portion of casing. Because first casing front end is monolithic structure, can show after the second casing passes through the screw fixation and sets up at first casing rear end and improve the holistic structural strength of casing, increase angle mill life, simple structure, the practicality is good.

Description

AC brushless angle grinder casing

Technical Field

The utility model belongs to decorate the electric tool field, specifically speaking relates to an exchange brushless angle mill casing.

Background

At present, the shell of the angle grinder in the field is of a split structure of a halved left shell and a halved right shell, the halved left shell and the halved right shell are fastened and fixed by screws, and the shell adopting the mode has poor integral structural strength and is easy to damage. Meanwhile, the whole radiating holes of the casing are arranged at the positions of the hand-held parts, so that the radiating holes are easily blocked when the casing is held by a hand, and poor radiating is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides an exchange brushless angle grinder casing for solving the technical problem.

The alternating current brushless angle grinder shell comprises a first shell and a second shell, wherein the front end of the first shell is of an integral structure, a motor accommodating space is arranged inside the front end of the first shell, the second shell is fixedly arranged at the rear end of the first shell through screws after being buckled with the first shell, a handheld part is formed in the middle of the whole shell after the second shell and the first shell are fixed, and an auxiliary electric appliance accommodating space is arranged inside the whole rear part of the shell.

Furthermore, a plurality of first heat dissipation holes and a plurality of second heat dissipation holes are formed in the first machine shell and the second machine shell at the rear part of the whole machine shell respectively.

Furthermore, the first heat dissipation hole and the second heat dissipation hole are respectively distributed at the rear ends of the first casing and the second casing.

Furthermore, the auxiliary electric appliance accommodating space arranged inside the integral rear part of the casing comprises a capacitor accommodating space, an adapter and a motor controller accommodating space.

Furthermore, the front end of the first housing is also provided with a plurality of groups of motor heat dissipation holes.
