Description

A fast clamping and fixing mechanism for a motor housing

technical field

The invention relates to a fast clamping and fixing mechanism for a motor casing, which is applied in the technical field of motor casing assembly.

Background technique

When assembling and installing the rear fan cover and the front cover of the existing motor housing, the operator does not use positioning and clamping operation for the assembly operation of the motor housing for the convenience of assembly. Although this saves operating time, the motor housing has no positioning. Clamping, the motor housing is easy to move or shake, which will cause inaccurate alignment of the positioning holes for assembly, and if the shaking motor housing is dumped, it will easily cause damage to the housing, and may cause injury to the assembler in severe cases. For this reason, We design a fast clamping and fixing mechanism for the motor housing.

detailed description

As shown in Figure 1, the present invention discloses a fast clamping and fixing mechanism for a motor housing, which includes: a motor housing 1, a bump 2, a threaded hole 3, a heat dissipation rib 4, and a motor base 5. Four bumps 2 are integrally formed by casting on the outer wall of the machine housing 1, each of which is provided with threaded holes 3, and the outer wall of the motor housing 1 is equiangularly spaced with several evenly distributed heat sinks. The rib plate 4, the bottom end of the motor housing 1 is cast and integrated to form a motor base 5, the motor base 5 is placed on the operating table 6, and the operating table 6 is engraved with anti-skid lines, which are used to increase The frictional force between the motor base 5 and the console 6 can prevent the motor housing 1 from slipping when assembled.

Both sides of the motor housing 1 on the console 6 are respectively provided with screw rods 7 connected perpendicularly to the console 6, and the screw rod 7 is provided with a positioning block 8 for sliding assembly installation, and the positioning block 8 is fixed by The bolt 10 is bolted in the threaded hole 3 on the bumps 2 on both sides of the motor housing 1, and forms a fixed connection with the motor housing 1. When the positioning block 8 is positioned and bolted to the bumps 2 on both sides, the The positioning block 8 is pinned and fixed on the screw rod 7 through a locking pin 9 .

The upper and lower sides of the motor housing 1 are respectively covered with an upper arc-shaped ferrule 11 and a lower arc-shaped ferrule 12, and the upper arc-shaped ferrule 11 and the lower arc-shaped ferrule 12 are in contact with the motor housing 1 up and down respectively. The upper and lower arc hoops 11 and 12 are horizontal ear seats 13 on both sides, and the upper and lower surfaces of the ear seats 13 are locked on the screw rod 7 by lock nuts 14.

The upper arc-shaped hoop 11 is consistent in shape and structure with the lower arc-shaped hoop 12, and the arc-shaped bending direction of the upper arc-shaped hoop 11 and the lower arc-shaped hoop 12 is oppositely arranged. A layer of cushioning rubber pad 15 is laid on the arc inner wall of the arc hoop 12 .

The present invention is implemented in this way: when the motor seat 5 of the motor housing 1 is placed on the console 6, screw rods 7 are arranged on both sides of the motor housing 1, and the positioning blocks 8 on the screw rod 7 slide to the motor housings on both sides. When the bump 2 of 1 is at the position, the positioning block 8 is bolted to the threaded hole 3 on the bump 2 through the fixing bolt 10 to form a fixed connection, and the positioning block 8 is locked on the screw rod 7 through the locking pin 9, so that the electric The positioning and clamping on both sides of the machine housing 1 is firm, avoiding the left and right sideslip and shaking of the motor housing 1; and the upper and lower sides of the motor housing 1 are respectively sleeved with an upper arc-shaped ferrule 11 and a lower arc-shaped ferrule 12 , the upper arc-shaped ferrule 11 and the lower arc-shaped ferrule 12 are in contact with the bumps 2 on the upper and lower ends of the motor housing 1 respectively, which can prevent the motor housing from shaking in the up and down direction. The upper arc-shaped ferrule 11 and the lower arc-shaped ferrule A buffer rubber pad 15 is arranged on the inner wall of the hoop 12 to protect the outer wall of the motor housing 1 and prevent the outer wall of the motor housing 1 from being squeezed and damaged.
