Description
Technical field
This utility model relates to a kind of electric motor car cubing, particularly relates to a kind of electric bicycle general inspection of head tube axiality
Tool.
Background technology
Electromobile frame head tube is one of vital part in the middle of car load vehicle frame, main and front fork component for electric bicycles,
Steering bearing be combined assembling, if the upper and lower coaxiality error of head tube cross conference directly influence car load ride comfortableness,
Stability etc., serious steering bearing causes stuck due to dislocation, the consequence of traumatic injury people.To vehicle frame head in existing electric motor car industry
The detection of pipe axiality is all to use three-dimensional coordinates measurement instrument or the through type detection of tradition one end.Three-dimensional coordinates measurement instrument carries out car
Head tube axiality detects, due to the big inconvenient operation of equipment volume so can not be widely used.Tradition one end through type test bar
Carrying out head tube axiality detection, its error is big, detection mode is incorrect, it is impossible to position with datum level, can only be according in one end
Other end endoporus error is detected in hole, and such detection mode is wrong.
Summary of the invention
This utility model purpose is the defect for the detection of existing electric bicycle head tube axiality, it is provided that a kind of structure
Simply, the electric bicycle head tube axiality universal check tool that detection mode is correct.
This utility model for achieving the above object, adopts the following technical scheme that
A kind of electric bicycle head tube axiality universal check tool, it is characterised in that: it includes base plate, is arranged on base plate both sides
Spacing base and thread rack, reference axis；There is on described thread rack the hollow thread briquetting threaded with thread rack；
It is coaxially arranged with hollow plug component, for inserting head tube two ends compression car between described screw thread briquetting and spacing base
Head tube；Described reference axis diameter adapts with plug component internal diameter and head tube internal diameter, by whether head tube can be passed
Judge that head tube axiality is the most qualified.
Its external diameter being further characterized by described plug component is φ 30mm, φ 43mm or φ 50mm.
Preferred: described cubing is provided with the lining connecting one end plug, for extending the length of one end plug.
It is provided with handle on described base plate.
This utility model assembles mode by referring to actual electric motor car, head tube two ends carries out screw thread and compresses locked, protect
Card two ends plug completely attaches to head tube datum end face, then with upper and lower inner hole after；By test bar (reference axis) from one end
Through the other end, if it is qualified to pass through just explanation head tube axiality, otherwise then judge defective.This utility model volume
Little, error is little, product manufacturing finished product is low, detection service efficiency is high, easy to use, be particularly well-suited to produce random detection；Improve
Detection efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model schematic top plan view.
Fig. 2 is this utility model front elevational schematic.
Detailed description of the invention
A kind of electric bicycle head tube axiality universal check tool, including base plate 201, is arranged on base plate 201 liang as shown in Figure 1, 2
The spacing base 108 of side and thread rack 102, reference axis 105, the handle 109 being arranged on base plate 201, lining 104.Described
There is on thread rack 102 the hollow thread briquetting 101 threaded with thread rack 102；Described screw thread briquetting 101 and spacing
Hollow plug component 103,106 it is coaxially arranged with, for inserting head tube two ends compression head tube between base 108.Stifled
Head assembly 103,106 is divided into: φ 30mm, φ 43mm, φ 50mm tri-kinds, is respectively suitable for head tube upper and lower aperture φ 30mm/ φ
Three kinds of electric bicycle head tube models that 30mm, φ 3mm0/ φ 43mm, φ 30mm/ φ 50mm are conventional.Cubing is additionally provided with connection one
The lining of end plug component 104, for extending the length of one end plug component 103 so that the head tube length adjustment model of detection
Enclose bigger.
During use, welding is completed or the head tube of no welding is parallel is placed on coaxiality check fixture, by head tube two ends
It is respectively put into the plug component 103,106 relative to size, then carries out rotating until compressing headstock with the screw thread briquetting 101 of one end
The plug component 103 at pipe two ends, 106(compress as far as possible, it is impossible to loosen)；Finally by reference axis 105(test bar) from screw thread briquetting
101 one end penetrate, and the judgement that can pass through is qualified, otherwise are substandard product.The upper and lower axiality of head tube allows by mistake
Difference controls (reference axis 105 and plug component by fit tolerance between reference axis 105 and plug component 103,106 internal diameter
103,106 minor diameter fit tolerance values should be less than equal to head tube upper and lower axiality allowable error value).
