Embodiment 1

[0049] In this embodiment, the elastic member adopts the shrapnel 4, such as Figure 4 Figure 8 As shown, the shrapnel 4 includes a rear section 4-1, an arched section 4-2 and a front section 4-3, and the rear section 4-1, the arched section 4-2 and the front section 4-3 are sequentially connected to form the main part of the shrapnel 4, The connection point of rear section 4-1 and arch section 4-2 forms a horizontal connection with the connection point of front section 4-3 and arch section 4-2, and the midline of the highest point of arch section 4-2 is different from the horizontal connection line. Coincidentally, in this embodiment, preferably, the highest point of the elastic sheet 4 is biased outward.

[0050] Such as Figure 6 , the front end of the output shaft 2 is hollow, the output shaft 2 has a through hole 3-1 communicating with the hollow part of the output shaft 2, the main part of the shrapnel 4 is placed in the hollow part of the output shaft 2, and the arch...

Embodiment 2

[0058] Such as Figure 9 , the elastic member in embodiment 2 adopts steel wire 5, and steel wire 5 has the characteristics of fast forming, and the structure of steel wire 5 is basically the same as that of shrapnel 4. After changing from shrapnel 4 to steel wire 5, its corresponding push rod 6 also has some changes. There are 4 limiting grooves 3 in the example, wherein there are through holes 3-1 on the two opposing limiting grooves 3, and there are two arched sections 4-2 of the steel wire 5, and the two arched sections 4-2 are connected to each other. Symmetrical, the two arched sections 4-2 protrude from the corresponding through holes 3-1 respectively, the push rod 6 has a tail part 6-7, and the tail part 6-7 is connected with the first journal 6-1, as Figure 10 , A notch 6-8 is provided on the tail part 6-7, and the rear section of the steel wire 5 is embedded in the notch 6-8, so that the rear section of the steel wire 5 is hooped on the end face of the first journal...

Embodiment 3

[0061] The difference between Embodiment 3 and Embodiment 1 lies in the unlocking mechanism. The unlocking mechanism of Embodiment 1 is to press the push rod 6 to cause radial deformation of the elastic member. This embodiment starts from another method (not shown) , using the method of rotating the push rod 6, the push rod is equipped with a cam, and the travel curve of the cam is used to make the shrapnel 4 open regularly or return to the normal state. When the shrapnel 4 is opened, the grinding head 1 cannot be removed , when the shrapnel 4 is in a non-expanded normal state, the grinding head can be quickly removed. In this way, the unlocking mechanism can also control the elastic member.

Abstract

The invention discloses a polishing head quick-detaching mechanism which is used for mounting of a polishing head. The polishing head quick-detaching mechanism comprises an output shaft which is used as power output of a polisher. According to the output shaft, polishing head periphery fixing can be achieved, the gravity center of a part for transmitting torque is changed in a jumping mode when the part rolls. The output shaft is provided with an elastic piece which protrudes out of the surface of the output shaft part where the elastic piece is placed. When the polishing head is arranged in the output shaft in a sleeved mode, the radial size of the elastic piece is under stress and is reduced. After the polishing head is arranged on the output shaft, the radial size of the elastic piece is restored to the original state. At the time, the elastic piece can limit axial separating of the polishing head. An unlocking mechanism is further included. The unlocking mechanism can have an effect on the elastic piece, so that the radial size of the elastic piece is reduced. When the polishing head is mounted, plastic deforming of the polishing head does not exist, deforming parts are all placed on the elastic piece, accordingly, the quick-detaching mechanism is low in relative loss, meanwhile, polishing head replacing is quick, and convenience and quickness are achieved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a mechanism for replacing a grinding head of a grinder. The invention provides a quick-release mechanism for a grinding head. Background technique [0002] With the rapid development of my country's economy, the amount of grinding in the mold industry, furniture industry, machining industry, etc. is also increasing. Due to the good grinding effect and high precision, it is very popular among users. The grinding currently used mainly includes the grinding host and the working head (ie the grinding head), such as figure 1 The structure diagram of the grinding head 1 is given. The grinding head 1 can be regarded as a standard part in this industry. Hole 1-1, the inner wall of the penetration hole 1-1 is divided into a straight part 1-2, a key part 1-3 and a limit part 1-4, wherein the straight part 1-2 is used as the Imported, the key part 1-3 can rotate the grinding head 1...
