Abstract
A substrate to be processed into an automotive steering gear rack has a round-bar shaped structure and is provided with a reducing section at the front and rear ends respectively, wherein the reducing section at the front end is internally provided with a middle positioning hole having a front opening; the reducing section at the rear end is internally provided with a slot having a rear opening and inwards extended to the middle part of a round bar; two ring slots are formed on the external wall on the middle part of the round bar at intervals; and a side positioning hole is formed on the external wall on the front part of the round bar. Due to the two positioning base points, i.e. the middle positioning hole and the side positioning hole, the substrate has the advantages of being precisely positioned and having high matching precision; and in addition, the processed automotive steering gear rack has the advantages of good quality, high precision and no rejection.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of substrate that is used to be processed into the automobile steering device tooth bar.
Background technology
The automobile steering device tooth bar is used in the automobile steering device, and its structure and making precision have influence on assembly precision, thereby have influence on the work life of whole automobile steering device.General method for making is, before being made into the automobile steering device tooth bar, does a substrate earlier, at one section round rod segment of substrate tooth bar of getting on the bus out, promptly becomes the automobile steering device tooth bar again, is used to cooperate other parts to be assembled into automobile steering device.The flank of tooth and end face have an angle requirement when drawing tooth road preface.Originally only at end face mesopore location, a location is set, it is inaccurate the location often to occur, and resetting is inaccurate, workman and operation amount degree etc. is required to be easy to generate waste product than higher, even damage cutter.
The utility model content
The purpose of this utility model in order to solve the problem that above-mentioned prior art exists, provides a kind of substrate that is used to be processed into the automobile steering device tooth bar exactly.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of substrate that is used to be processed into the automobile steering device tooth bar, be the round bar shape framing member, its front-end and back-end are respectively equipped with a undergauge section, in front end undergauge section, be provided with to the location of open front mesopore, in the undergauge section of rear end, be provided with aft-opening slotted eye and extend inwardly to the middle part of round bar; Be interval with two annular grooves at the middle part of round bar outer wall, be provided with a location side opening at the anterior outer wall of round bar.
Described location side opening is a flared hole.
Also being provided with two radial holes on the described round bar is communicated with slotted eye two ends in the round bar respectively.
The utility model is used to be processed into the substrate of automobile steering device tooth bar owing to be provided with two setting bases, promptly locatees mesopore and a location side opening, accurate positioning for one, the quality of fit height, the automobile steering device tooth bar quality that is processed into is good, and the precision height can not produce waste product.
