The testing tool that is used for car steering tube column guard shield size detection
Technical field
The invention belongs to the detection technique field that auto parts are produced, be specifically related to be used for the testing tool of car steering tube column guard shield size detection.
Background technology
At present, the detection means of car steering tube column guard shield mainly is by the testing staff detected member to be carried out common manual inspection.The steering column guard shield not only will detect all dimensional parameters on the guard shield; Also to detect the angle of inclination of steering column guard shield, the inclined height of steering column guard shield, tapering of steering column guard shield or the like; Because detected member complex structure; The parameter that need detect is various, so not only workload is big for this detection mode, and does not note slightly causing bigger detection error.Because detection of complex is loaded down with trivial details, had a strong impact on detection speed in addition, examined velocity effect, even parts can not in time be sent to the situation of station can cause car load to produce the time.
Summary of the invention
In order to improve the accuracy of detection efficiency and detection, the present invention provides a kind of simple in structure, easy to operate testing tool that is used for car steering tube column guard shield size detection.
Concrete technology of the present invention is following:
The testing tool that is used for car steering tube column guard shield size detection comprises the base plate of rectangle; Length direction one side of said base plate is provided with the detection body; Detecting body is inverted L shaped riser; The length direction opposite side both sides of base plate symmetry respectively are uniformly distributed with and offer three stick harness holes, cooperate respectively in the stick harness hole of both sides symmetry to be inserted with A stick harness, B stick harness and C stick harness, and the abutting end in said three stick harnesses and stick harness hole is the test side; Said detection upper part of body cooperation is provided with the height detection piece.
Said detection upper part of body offers and detects the piece groove, and the middle lower portion of said height detection piece offers through slot, makes height detection piece and detection body be the tabular grafting of cross.
The detection body both sides that contact with base plate are respectively equipped with leg-of-mutton back-up block.
The diameter of said A stick harness test side is that the diameter of 7mm, C stick harness test side is 14mm; The test side of B stick harness is a waist shape piece, and the length of waist shape piece is 11mm, and width is 6.5mm.
Useful technique effect of the present invention is embodied in the following aspects:
1. testing tool of the present invention is simple in structure; Easy to operate; And can position the detection of installing to steering column guard shield to be detected, use the present invention to detect the required time of steering column guard shield and be merely and have 10% of manual detection required time now, improve detection efficiency with the size all standing;
2. use testing tool of the present invention, whether the mounting hole site and relative position, the size suitable for reading that can accurately detect the steering column guard shield be qualified, and whether steering column guard shield bottom margin profile is qualified, improved seized veracity of parameters in the testing process greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the detected state synoptic diagram.
Sequence number among the last figure: base plate 1, A stick harness 2, B stick harness 3, C stick harness 4, detection body 5, back-up block 6, height detection piece 7, steering column guard shield 8.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1, the testing tool that is used for car steering tube column guard shield size detection comprises the base plate 1 of rectangle, and length direction one side of base plate 1 is installed with and detects body 5, and detection body 5 both sides that contact with base plate 1 are installed with leg-of-mutton back-up block 6 respectively.Detecting body 5 be inverted L shaped riser, and the length direction opposite side both sides of base plate 1 symmetry respectively are uniformly distributed with and offer three stick harness holes, in the stick harness hole of both sides symmetry respectively cooperation be fitted with A stick harness 2, B stick harness 3 and C stick harness 4.The top of detecting body 5 offers detects the piece groove, and the middle lower portion of height detection piece 7 offers through slot, and height detection piece 7 is the tabular grafting of cross with detection body 5.The diameter of A stick harness test side is that the diameter of 7mm, C stick harness test side is 14mm; The test side of B stick harness is a waist shape piece, and the length of waist shape piece is 11mm, and width is 6.5mm.
During detecting operation, at first steering column guard shield 8 is positioned on the base plate 1, then height detection piece 7 is inserted in the detection piece groove that detects body 5 tops, realize detection steering column guard shield 8 height; Again A stick harness 2, B stick harness 3 and C stick harness 4 are inserted to respectively in the corresponding mounting hole in steering column guard shield 8 bottom surfaces, realize the detection of steering column guard shield 8 bottom surface mounting holes and the detection of bottom margin profile.
