Problems solved by technology

[0004]Because this surface treatment device adopts the connection between the transmission system and the working head as a ball joint, the transmission part and the working head part are positioned mutually through the connection system, and the ball The ball center of the head and the rotation axis of the three-dimensional rotation of the working head are concentric, which makes the processing of the material complicated and the stability of the structure is not good

Embodiment Construction

[0017] see figure 1 , a surface treatment device, including a housing 1, a motor 3 arranged in the housing 1, a transmission shaft 7 matched with the motor 3, and a working head 2 connected with the transmission shaft 7.

[0018] The surface treatment device can be a sander or a polishing machine.

[0019] The casing 1 includes an upper base plate 11 and a lower base plate 12 , a gear box 10 is formed between the upper base plate 11 and the lower base plate 12 . A receiving portion 8 is disposed in the lower bottom plate 12 . see further Figure 5 The accommodating portion 8 includes a first accommodating portion 81 extending outward of the housing 1 , a second accommodating portion 82 extending inward of the housing, and a connecting portion 83 connecting the first accommodating portion 81 and the second accommodating portion 82 . Wherein, the first accommodating portion 81 has a spherical first inner surface 81a and a hole 81b, and the second accommodating portion 82 has...

Abstract

A surface treating apparatus is composed of a casing with an internal cavity, a motor, a drive axle matched with said motor and with a slot, a working head matched with said drive axle in said internal cavity, a locating element fixed in said slot on drive axle, and a pin matched with said locating element and with both ends in said working head.

Description

technical field [0001] The invention relates to a surface treatment device, in particular to a surface treatment device with a swingable working head. Background technique [0002] Traditional surface treatment devices generally include sanders, angle grinders and polishing machines, which generally include a housing, a motor disposed in the housing, a working head, and a transmission shaft connecting the motor and the working head, and the working head and the transmission The shaft is set at a fixed angle. During the working process, the working head cannot swing at a certain angle around its axis. Therefore, this type of transmission surface treatment device is more suitable for processing flat surfaces, but the effect of processing curved surfaces is less. [0003] U.S. Publication No. 6244943 discloses a surface treatment device mainly used for processing curved surfaces, which includes a housing, a transmission, a working head and a transmission shaft connecting the t...
