Abstract
The utility model discloses a guidance nut of a train brake shoes stack adjuster. In the process of producing a guidance nut, a guidance nut body and guidance nut meshing teeth are formed respectively in a casting manner through using the lost foam process, and then are spliced; the tooth profile parts of the guidance nut meshing teeth are formed through adopting a mold material, and then spliced into a whole; and the tooth profile is directly cast. Therefore, both the production efficiency and the precision of products are improved; the requirements of the conventional production technology are satisfied; the problem existing in the past is solved better; the manufacturing cost is reduced; and the guidance nut with an excellent performance is provided, and has an excellent application value.
Description
Technical field
The utility model belongs to trailer-car brake and transfers the device field, relates in particular to a kind of trailer-car brake and transfers the device guiding nut.
Background technique
During guiding nut on trailer-car brake accent device was produced, traditional essence casting directly cast out the mould that deforms, disappears and can't realize little tooth moulding, does not cast out machining difficulty, poor efficiency, low precision and cost height.
The model utility content
The purpose of this utility model is to utilize a kind of trailer-car brake to transfer the device guiding nut, is intended to solve the processing difficulties that existing manufacturing process exists, cost height, the problem that manufacturing efficiency is low.
The purpose of this utility model is to provide a kind of trailer-car brake to transfer the device guiding nut, and described guiding nut comprises: guiding nut body and guiding nut engaging tooth; Described guiding nut engaging tooth is arranged on the described guiding nut body.
Further, described guiding nut body and guiding nut engaging tooth adopt disappearance mold technique casting respectively.
Further, the parts of tooth of described guiding nut engaging tooth adopts the moulding of high density mould material.
The trailer-car brake that the utility model provides is transferred the device guiding nut, by with guiding nut body and guiding nut engaging tooth decibel casting, satisfied the requirement of existing one-tenth production. art, improved the precision of product, the output that helps high quality of products has satisfied client's demand; The parts of tooth of guiding nut engaging tooth adopts the moulding of high density mould material, and tooth is cast in splicing earlier again, has reduced to become to produce cost, has improved the efficient of producing, and preparation process is simple and practical, has good using value.

Fig. 2 is that the trailer-car brake that the utility model embodiment provides is transferred device guiding nut left view
Fig. 3 is that the trailer-car brake that the utility model embodiment provides is transferred device guiding nut sectional view.
Among the figure: 1, guiding nut body; 2, guiding nut engaging tooth.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of trailer-car brake to transfer the device guiding nut, and this guiding nut comprises: guiding nut body and guiding nut engaging tooth; The guiding nut engaging tooth is arranged on the guiding nut body.
As the utility model embodiment's a optimized project, guiding nut body and guiding nut engaging tooth adopt disappearance mold technique casting respectively.
As the utility model embodiment's a optimized project, the parts of tooth of guiding nut engaging tooth adopts the moulding of high density mould material.
Following with reference to accompanying drawing, transfer device to describe in further detail with guiding nut to the utility model embodiment trailer-car brake.
As Fig. 1, Fig. 2 and shown in Figure 3, trailer-car brake of the present utility model transfers device to be made up of guiding nut body 1 and guiding nut engaging tooth 2 with guiding nut, guiding nut in the utility model contains 60 tooth depths less than the guiding nut engaging tooth 2 of 2mm, and size is little but high to the profile accuracy requirement; Working process is, by the disappearance mold technique, with guiding nut body 1 and guiding nut engaging tooth 2 difference castings, the parts of tooth of guiding nut engaging tooth 2 adopts the moulding of high density mould material, be spliced into integral body then, directly cast out profile of tooth, realize efficient, low-cost batch production.
The trailer-car brake that the utility model embodiment provides is transferred the device guiding nut, by with guiding nut body and guiding nut engaging tooth decibel casting, satisfied the requirement of existing one-tenth production. art, improved the precision of product, the output that helps high quality of products has satisfied client's demand; The parts of tooth of guiding nut engaging tooth adopts the moulding of high density mould material, and tooth is cast in splicing earlier again, has reduced to become to produce cost, has improved the efficient of producing, and preparation process is simple and practical, has good using value.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
