Abstract
The utility model discloses a car direction machine spline connecting rod cover that static pressure finish rolling takes shape, including transmission guide arm, internal spline, it is as an organic whole that transmission guide arm and internal spline pass through static pressure finish rolling, the internal spline is arranged in the inner chamber of transmission guide arm, and seamless static pressure finish rolling has internal spline installation auxiliary member in the inner chamber of internal spline. Its internal spline is processed to technique that this car direction machine spline connecting rod cover that static pressure finish rolling takes shape adopted hollow steel pipe to take shape through static pressure finish rolling, and the cost space is fallen for this product provides great to this technique to its mechanical properties has been improved.
Description
Technical field
This utility model relates to area of medical devices, the training gear of vehicle spline connecting rod set that a kind of static pressure finish rolling shapes.
Background technology
Connecting rod set is one of parts of training gear of vehicle key, and its assembly traditional processing technology is that after being welded by internal spline and transmission guide rod two parts, machining forms.Production technology is complex, and machining accuracy is difficult to ensure that, especially weld strength, the machining accuracy of internal spline and internal spline and the axiality in guide rod portion, be the key point determining whole vehicle safety travel.At present, the production technology of this part is to use round steel to be first machined into method to be processed into hollow materials in the tube, process internal spline through broaching machine, use ion arc-welding spline housing and roughwrought transmission guide rod to be welded together, then ensure the axiality of product through grinding.This traditional design and production technology, its shortcoming is mainly reflected in: one is that utilization rate of raw materials is the lowest；Two is that the long cost of production process is high；Three is that production efficiency is low；Four is welding position lies dormant potential safety hazard in vehicle runs.In order to solve this problem, it is proposed that the training gear of vehicle spline connecting rod set that a kind of static pressure finish rolling shapes.
Utility model content
The purpose of this utility model is the training gear of vehicle spline connecting rod set providing a kind of static pressure finish rolling to shape, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: the training gear of vehicle spline connecting rod set that a kind of static pressure finish rolling shapes, including transmission guide rod, internal spline, described transmission guide rod and internal spline are integrated by static pressure finish rolling, described internal spline is positioned in the inner chamber of transmission guide rod, and in the inner chamber of internal spline, seamless static pressure finish rolling has internal spline installing auxiliary part.
Preferably, described transmission guide rod is hollow circuit cylinder shape steel tube.
Preferably, described internal spline and internal spline installing auxiliary part are all in Chinese character crosswise.
Preferably, the corner of described internal spline is provided with the groove extended to inner side.
Preferably, described internal spline is provided with, with the contact surface of transmission guide rod, the projection that the cambered surface with transmission guide rod cooperates.
Preferably, the external diameter of described internal spline installing auxiliary part is equal with the internal diameter of internal spline.
Compared with prior art, the beneficial effects of the utility model are: the training gear of vehicle spline connecting rod set that this static pressure finish rolling shapes uses technology that hollow steel pipe shapes through static pressure finish rolling to process its internal spline, this technology is that this product provides bigger cost declining space, and improves its mechanical performance.Replace traditional Machining Technology for Cutting with without cutting static pressure finish rolling process technology, make raw material usage amount reduce more than %, saving steel resource, greatly reduce the direct cost of product；Static pressure finish rolling process technology improves the micro structure of material, makes tissue finer and close, and intensity is improved, and extends the service life of material, improves product safety reliability；After adopting new technology, the structure design of product can be optimized, simplify production technology, improve productivity effect, reduction production cost.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-4, a kind of technical scheme of this utility model offer: the training gear of vehicle spline connecting rod set that a kind of static pressure finish rolling shapes, including transmission guide rod 1, described transmission guide rod 1 is hollow circuit cylinder shape steel tube, internal spline 2, described transmission guide rod 1 and internal spline 2 are integrated by static pressure finish rolling, described internal spline 2 is provided with, with the contact surface of transmission guide rod 1, the projection that the cambered surface with transmission guide rod 1 cooperates, use the technology mode that static pressure finish rolling shapes, make transmission guide rod 1 that this training gear of vehicle spline connecting rod overlaps and internal spline 2 by assembling die in the effect of static pressure once property shape, transmission guide rod 1 and internal spline 2 part are directly becoming an overall structure, transmission guide rod 1 and internal spline 2 after static pressure finish rolling shaping coordinate entrucking to use.Described internal spline 2 and internal spline installing auxiliary part 3 are all in Chinese character crosswise, described internal spline 2 is positioned in the inner chamber of transmission guide rod 1, and seamless static pressure finish rolling has internal spline installing auxiliary part 3 in the inner chamber of internal spline 2, the external diameter of described internal spline installing auxiliary part 3 is equal with the internal diameter of internal spline 2, the corner of described internal spline 2 is provided with the groove extended to inner side, the technology that this training gear of vehicle spline connecting rod set uses hollow steel pipe to shape through static pressure finish rolling processes its internal spline, this technology is that this product provides bigger cost declining space, and improves its mechanical performance.Replace traditional Machining Technology for Cutting with without cutting static pressure finish rolling process technology, make raw material usage amount minimizing more than 60%, saving steel resource, greatly reduce the direct cost of product；Static pressure finish rolling process technology improves the micro structure of material, makes tissue finer and close, and intensity is improved, and extends the service life of material, improves product safety reliability；After adopting new technology, the structure design of product can be optimized, simplify production technology, improve productivity effect, reduction production cost.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
