Abstract

The utility model discloses an expanding tire device for a magnetic steel hub. The expanding tire device comprises a worktable, wherein a cylindrical expanding tire consisting of at least two identical expanding blocks is arranged on the worktable; and a draw bar which is used for outwards expanding the expanding blocks is arranged in the center of the expanding tire. The cylindrical expanding tire consisting of the expanding blocks with the same structures is arranged on the worktable, the draw bar is arranged in the center of the expanding tire, and after the hub is placed on the expanding tire, the expanding tire is outwards expanded under the action of the draw bar, so that the hub is adjusted and machined. Compared with the prior art, the expanding tire device for the magnetic steel hub has the characteristics of simple structure, low cost, convenience and practicality.

Description

A kind of magnet steel wheel hub device of tyre that expands
Technical field
The utility model belongs to the electric bicycle motor technical field, relates to the swollen device of tyre of a kind of magnet steel wheel hub.
Background technology
The magnet steel wheel hub of electric bicycle for product requirement needs, all needs the magnet steel wheel hub is proofreaied and correct, with the requirement of satisfying the market after producing in process of production.Then, because the means for correcting complicated structure that the magnet steel wheel hub adopts is proofreaied and correct by present magnet steel wheel hub manufacturer, and cost is high, thereby has not only strengthened the production and processing cost of manufacturer, nor is beneficial to the maintenance in the use procedure.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure and effective magnet steel wheel hub device of tyre that expands.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of magnet steel wheel hub device of tyre that expands comprises workbench, is provided with the swollen tire of cylinder formula that at least two identical expansion blocks consist of at described workbench, is provided with for the pull bar with the outside distending of described expansion block in described swollen tire central authorities.
Described swollen tire is to be made of the identical expansion block of 6 block sizes.
Be provided with gathering sill at described workbench, described expansion block is installed in the described gathering sill.
The utility model is by arranging the swollen tire of the cylinder formula that is made of the identical expansion block of structure at workbench, be provided with pull bar in described swollen tire central authorities, after wheel hub is placed on the swollen tire, under the pull bar effect with the outside distending of described swollen tire, thereby realized the correction of wheel hub is processed; Compared with prior art, the utlity model has characteristics simple in structure, that cost is low, convenient and practical.
Description of drawings
Fig. 1 is the structural representation of the swollen device of tyre of a kind of magnet steel wheel hub of providing of the utility model embodiment;
Fig. 2 is the plan structure schematic diagram of the swollen device of tyre of the magnet steel wheel hub that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Fig. 1 ~ 2, a kind of magnet steel wheel hub device of tyre that expands comprises workbench 1, is provided with the swollen tire of cylinder formula that at least two identical expansion blocks 2 consist of at described workbench, is provided with for the pull bar 3 with described expansion block 2 outside distendings in described swollen tire central authorities.
Described expansion block 2 links together by extension spring.
More excellent, described swollen tire is to be made of the identical expansion block of 6 block sizes.
Be provided with gathering sill at described workbench, described expansion block is installed in the described gathering sill.
Further, be provided with gulde edge in the upper and lower side outside of described expansion block.
During use, the magnet steel wheel hub is enclosed within on the described swollen tire excircle, then starts oil cylinder, drive described pull bar and move downward, because pull bar moves downward the generation squeezing action, described expansion block is outwards pushed, and move along the gathering sill on the workbench, thereby realized correction to the magnet steel wheel hub.
The utility model is by arranging the swollen tire of the cylinder formula that is made of the identical expansion block of structure at workbench, be provided with pull bar in described swollen tire central authorities, after wheel hub is placed on the swollen tire, under the pull bar effect with the outside distending of described swollen tire, thereby realized the correction of wheel hub is processed; Compared with prior art, the utlity model has characteristics simple in structure, that cost is low, convenient and practical.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
