Description

Lid cubing on a kind of steering column

Technical field

Invention belongs to auto-parts detection technique field, and in particular to lid cubing on a kind of steering column.

Background technology

, it is necessary to modeling with cubing to punching, hot pressing and injection moulding when manufacturing exterior part in body of a motor car plastics The shape position error of exterior part is tested in material；The detection of exterior part shape position error point body detection in body of a motor car plastics Two types are detected with assembly, body is detected as the detection to the shape position error of body of exterior part in plastics in itself, assembly inspection Survey is at TAC (Total Assembly Checking Fixture) by the overall actual assembled of exterior part composition in plastics one In vehicle cubing, exterior part in plastics is detected with the shape position error of miscellaneous part mated condition.

Actually make at present in car, the form tolerance control of automobile component relies primarily on the control of plastic components and debugging is more than Sheet metal member, intrinsic tolerance is met to reach；Steering column lid as driver in automotive trim be easiest to watch attentively it is visual Face, its Geometrical Tolerance Principle is strict；In the prior art, general cubing detection is single, to meet based on the form and position tolerance of body, So that underproof phenomenon occurs in upper vehicle cubing, made troubles to car is made.

The content of the invention

For above-mentioned deficiency, the invention provides lid cubing on a kind of steering column, the present invention simulates actual entrucking, The mode of actual installation is simulated using simulated block, it is high with the degree of accuracy, the efficiency of allowance control and debugging greatly improved.

To achieve these goals, the technical solution adopted by the present invention is as follows：

Lid cubing on a kind of steering column, it is characterised in that simulated block I, simulated block II including base, above base, Simulated block III, simulated block IV and simulated block V, wherein simulated block I, simulated block III respectively with simulated block II, simulated block IV shapes Size is identical and positional symmetry is installed on both sides side by side, and the simulated block V is arranged between simulated block I and simulated block III.

Specifically, setting the fixture block covered on restricted steering column card radially movable with axial direction on described piece of I, simulated block II Button Block, for detecting the steering indicating light rod aperture tangent plane body of lid steering indicating light rod aperture gap and face difference on steering column, for detecting steering column The datum hole of the reference pins position of upper lid.

Specifically, being provided with the fixture block radial direction and axial direction covered on restricted steering column on the simulated block III, simulated block IV Activity snap seats, for detect the groove of lid reinforcement position on steering column, for detect with steering column on cover reference pins The datum hole of position.

Specifically, the simulated block V is provided with the steering that lid steering wheel assembly rod aperture gap differs from face on detection steering column Rod aperture tangent plane body.

Specifically, the position of the snap seats is interference fit with the fixture block of lid on steering column；The steering indicating light rod aperture is cut It is that gap coordinates that face body turns to lamp hole with lid on steering column；The groove is with lid reinforcement on steering column for gap coordinates；It is described Datum hole is interference fits with the reference pins of lid on steering column；The steering rod aperture tangent plane body and lid turning-bar on detection steering column Hole coordinates for gap.

In sum, as a result of such scheme, the present invention has advantages below to the present invention：

(1) present invention simulates the mode of actual installation using simulated block by simulating actual entrucking, preferably on control steering column The injection deformation ratio of lid, and where undesirable can be drawn by record data, injection debugging is carried out, improve work Efficiency.

Specific embodiment

With reference to embodiment to lid cubing on a kind of steering column of the invention, it is described further.

Embodiment 1：

Lid cubing on a kind of steering column, as Figure 1-5, including base 1, simulated block I2, simulated block installed in the top of base 1 II3, simulated block III4, simulated block IV5 and simulated block V6, wherein simulated block I2, simulated block III4 respectively with simulated block II3, mould Plan block IV5 shape sizes are identical and positional symmetry is installed on both sides side by side, and simulated block V6 is arranged on simulated block I2 and simulated block Between III4；The fixture block covered on restricted steering column snap seats 7, use radially with axial direction activity is set on block I2, simulated block II3 In the steering indicating light rod aperture tangent plane body 8 of lid steering indicating light rod aperture gap and face difference on detection steering column, for detecting what is covered on steering column The datum hole 9 of reference pins position；Be provided with simulated block III4, simulated block IV5 on restricted steering column cover fixture block radially with Axially activity snap seats 7, for detect the groove 10 of lid reinforcement position on steering column, for detect with steering column on cover The datum hole 9 of reference pins position；Simulated block V6 is provided with lid steering wheel assembly rod aperture gap and turning that face differs from detection steering column To rod aperture tangent plane body 11；The position of snap seats 7 is interference fit with the fixture block of lid on steering column；Steering indicating light rod aperture tangent plane body 8 with Covered on steering column and turn to lamp hole for gap coordinates；Groove 10 is with lid reinforcement on steering column for gap coordinates；Datum hole 9 and steering The reference pins covered on post are interference fits；Turn to rod aperture tangent plane body 11 and turn to rod aperture for gap coordinates with lid on detection steering column.
