Abstract
The utility model discloses a kind of a movable armature for elevator traction machine, comprise: armature main body, described armature main body is provided with counterbore, and described counterbore is stepped, described stair-stepping diameter reduces from described armature body surfaces gradually to baseplane, and the baseplane of described counterbore is provided with a wedge angle.The utility model reasonable in design, the baseplane of counterbore designs one and allows the wedge angle leaving drill-shape, is convenient to processing, can not produce dot at the center of counterbore baseplane and affect assembling.Which enhance production efficiency, directly reduce productive costs.
Description
Technical field
The utility model relates to a kind of elevator traction machine, and specifically, what relate to is a kind of a movable armature for elevator traction machine, is the parts of elevator machine brake.
Background technology
Along with the process of urbanization, the development of real estate and commercial real estate, skyscraper gets more and more, increasing to the demand of elevator.
Do not consider fabrication properties and product operating needs during a movable armature product design of existing elevator traction machine, product counterbore base requires flat, causes counterbore to add man-hour, more complicated.Need first to hole, rear end mil cutter inserts milling, and finally prevent the center of counterbore baseplane from producing dot and affecting assembling, need the milling cutter with minor diameter, carry out circular interpolation milling in baseplane, this design causes, and at the bottom of production efficiency, cost is high.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of a movable armature for elevator traction machine, can enhance productivity, directly reduce productive costs.
For realizing above-mentioned object, a kind of a movable armature for elevator traction machine described in the utility model, comprise: armature main body, described armature main body is provided with counterbore, described counterbore is stepped, described stair-stepping diameter reduces from described armature body surfaces gradually to baseplane, and the baseplane of described counterbore is provided with a wedge angle.
Preferably, the mating shapes of described angular shape and processing drill.
Preferably, described wedge angle is positioned at the center of the baseplane of described counterbore.
Preferably, the angle of described wedge angle is greater than 90 degree and is less than 180 degree.
The utility model beneficial effect:
The utility model reasonable in design, the baseplane of counterbore designs one and allows the wedge angle leaving drill-shape, is convenient to processing, can not produce dot at the center of counterbore baseplane and affect assembling.Which enhance production efficiency, directly reduce productive costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the section-drawing of D-D shown in Fig. 1;
In figure: armature main body 1, counterbore 2, wedge angle 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1-2, the present embodiment provides a kind of a movable armature for elevator traction machine, comprise: armature main body 1, described armature main body 1 is provided with counterbore 2, described counterbore 2 is stepped, described stair-stepping diameter reduces from described armature body surfaces gradually to baseplane, and the baseplane of described counterbore is provided with a wedge angle 3.
The mating shapes of described angular shape and processing drill.
Described wedge angle is positioned at the center of the baseplane of described counterbore.
The angle of described wedge angle is greater than 90 degree and is less than 180 degree.
The utility model reasonable in design, the baseplane of counterbore designs one and allows the wedge angle leaving drill-shape, be convenient to processing, adding man-hour drill bit so directly beats darker, then directly insert milling with flat-bottom end mill just can complete, can not dot be produced at the center of counterbore baseplane and affect assembling.Which enhance production efficiency, directly reduce productive costs.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
