Problems solved by technology
However, the position of the collet body on the existing electric pipe expander is often unable to be adjusted, resulting in long-term use of the pipe expander. Replacing the chuck body or even the pipe expander will reduce the service life of the pipe expander and increase the user's cost
[0003] Chinese utility model 201920403433.X discloses a chuck body clamping adjustment structure of an electric pipe expander, which mainly fixes the chuck body through a connecting rod mechanism arranged in the connecting rod accommodation chamber; however, the connecting rod mechanism There are many overall parts, which will make it have more connection points. After the linkage mechanism of this structure is used for a long time, the connection points between the linkages are prone to loosening, which will cause the overall linkage mechanism to loosen and affect the clamping. effect; moreover, there are many integral parts of the linkage mechanism, which is complicated to assemble and not easy to use

Embodiment Construction
[0054] Below in conjunction with specific embodiment the patent of the present invention is described further:
[0055] An electric pipe expander, comprising a pipe expander main body 7, on which a chuck 2 is arranged, and the pipe fitting to be processed is clamped in the pipe expander main body 7, and an automatic reciprocating The rotating eccentric conical head automatically expands the pipe fixed on the chuck 2 through the automatic reciprocating rotation of the eccentric conical head; the main body 7 of the pipe expander also includes a handle for holding the entire electric pipe expander.
[0056] The electric pipe expander is also equipped with a clamping mechanism, which is used to clamp and fix the chuck 2 located in the placement chamber 1 during use, so as to prevent the pipe expansion from being affected by the offset of the chuck 2 in the placement chamber 1 effect; specifically, as figure 2 , 3 As shown, in addition to the above-mentioned placement cavity 1, ...

The invention belongs to the technical field of electric tools, and particularly relates to a chuck clamping mechanism of an electric pipe expander and the electric pipe expander. The chuck clamping mechanism comprises a containing seat and a handle, a containing cavity is formed in the containing seat, and a chuck for clamping a pipe fitting to be machined is arranged in the containing cavity; and the handle is rotatably arranged on one side of the containing seat, and an abutting part is arranged on the handle and extends into the containing cavity; and the handle is rotated to drive the abutting part to abut against the chuck in the containing cavity so as to clamp the chuck. The chuck is clamped in a handle rotating abutting mode, compared with a connecting rod mechanism, the number ofrotating points is small, the number of needed combined parts is small, and therefore compared with manufacturing, more convenience is achieved, and the overall structure is more stable; and therefore, the situation that an abutting point is loosened due to abrasion of the rotating points after a product is used for a long time is avoided.
Description
technical field [0001] The patent of the invention belongs to the technical field of electric tools, and particularly refers to a chuck clamping mechanism of an electric pipe expander and the electric pipe expander thereof. Background technique [0002] The eccentric pipe expander is a pipe expansion tool for connecting various pipes and pipes, pipes and containers in refrigeration, petroleum, chemical, shipbuilding, electric power and other industries. The pipe is expanded by the continuous rotation of the conical eccentric head. Existing pipe expanders generally include manual pipe expanders and electric pipe expanders. Manual pipe expanders have the advantages of small size and light weight. The electric pipe expander has the advantages of saving time and effort in pipe expansion processing, and high pipe expansion efficiency, so it is increasingly popular and used. However, the position of the chuck body on the existing electric pipe expander is often unable to be adjus...
