Description

Detection jig

Technical Field

The utility model relates to a quality testing technical field especially relates to a detection tool.

Background

On-vehicle LCD screen backplate needs the binding, need inspect the binding quality after the binding is accomplished, and traditional detection binding technology will adorn a plurality of nail products and put into the flat board that has the straight hole and detect, because nail and hole fit clearance are little, just be difficult for putting into detection tool when a nail inclines slightly (in tolerance range), as shown in fig. 4, inefficiency, easy bending off with the fingers and thumb product nail department when operating personnel detects the completion back and takes out the product in addition.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a detection tool is provided to overcome not enough among the above-mentioned prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows: the utility model provides a detection tool, its includes the template at least, and each nail department on corresponding the product on the template all is equipped with the step hole, and the step hole is including consecutive taper hole, via hole a and via hole b, and the footpath end of taper hole is connected with via hole a, and the internal diameter of via hole b is greater than the internal diameter of via hole a, and the internal diameter of via hole a is greater than the diameter of nail, and the hole depth of taper hole is less than the length of nail.

The utility model has the advantages that: the oblique angle of taper hole plays and leads positive effect when utensil is put into to the product, and operating personnel can not break curved product nail off with the fingers and thumb when taking out the product, avoids leading to the product secondary to destroy, and it is easier to reduce to examine the straight body position of nail and ensure to put into the product and take out the product, can not warp moreover, can high-efficiently detect out the relative position degree of nail, has improved production efficiency, has reduced manufacturing cost.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Further: the taper angle of the taper hole is 60 degrees +/-2 degrees.

Further: the hole depth of the via hole a is 1.3mm-1.7 mm.

Further: the difference between the radius of the via hole a and the radius of the nail is 0.2mm-0.5 mm.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Example 1

As shown in fig. 1 to 3, a detection fixture at least includes a template 1, where the template 1 is provided with a stepped hole 110 at each nail position corresponding to a product, in general, the stepped hole 110 at least penetrates through one end surface of the template 1, and in this embodiment, it is preferable that the stepped hole 110 penetrates through both upper and lower end surfaces of the template 1, the stepped hole 110 includes a tapered hole 111, a via hole a112, and a via hole b113 connected in sequence, and it is preferable that the stepped hole 110 includes a tapered hole 111, a via hole a112, and a via hole b113 connected in sequence from top to bottom, a small-diameter end of the tapered hole 111 is connected to the via hole a112, an inner diameter of the via hole b113 is larger than an inner diameter of the via hole a112, an inner diameter of the via hole a112 is larger than a diameter of a nail, and a depth of.

Embodiment 2, as shown in fig. 1 to 3, this embodiment is further optimized based on embodiment 1, and specifically includes the following steps:

the taper angle of the taper hole 111 is preferably 60 ° ± 2 ° to facilitate nail introduction, and when the specific value is 58 °, 60 °, 62 ° or any other specific value in the interval.

Embodiment 3, as shown in fig. 1 to 3, this embodiment is further optimized based on embodiment 1 or 2, and specifically includes the following steps:

the hole depth of the via hole a112 is preferably 1.3mm-1.7mm, and more preferably 1.5mm, and the difference between the radius of the via hole a112 and the radius of the pin is preferably 0.2mm-0.5mm, and more preferably 0.5mm, through calculation and numerical simulation, this parameter and structure can ensure the position tolerance of the pin, and also facilitate product taking and placing, and the inner diameter of the via hole b113 is larger than the inner diameter of the via hole a112, so that the via hole b113 forms a clearance relative to the pin, or facilitates other product detection.

Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
