Description

Peeling force measuring jig

Technical Field

The utility model belongs to the technical field of high-accuracy communication or cell-phone electronic component shield cover, it measures the tool to involve peeling strength.

Background

When a bottom component of a high-precision communication or mobile phone electronic component shielding case is damaged, a covering part needs to be peeled off, and the peeling force of the covering part needs to be in a proper range so as to prevent the damage of welding below. The existing stripping force testing machine is expensive to purchase, complex in structure and incapable of being adjusted according to actual testing requirements.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: provided is a peeling force measuring device which has a simple structure, is low in cost, and can be flexibly changed.

In order to achieve the above purpose, the utility model provides a technical scheme as follows:

the stripping force measuring jig comprises a clamp, a slide rail, a base and a torque dial wrench, wherein two bearing seats are arranged in the base, a shaft lever is arranged in the two bearing seats, and the torque dial wrench is fixedly connected with the end part of the shaft lever; the slide rail is arranged in the base, the guiding direction of the slide rail is vertical to the central shaft of the shaft lever, and the clamp is connected to the slide rail in a sliding mode through a slide block; the shaft lever is provided with a rope through hole, and a rope is arranged in the rope through hole in a penetrating manner.

In this technical scheme, put the shield cover location centre gripping in anchor clamps, tie up the one end of rope on the cover portion again, along with the rotation of torsion bottle opener, anchor clamps pass through the slide rail and move to the axostylus axostyle under, along with the increase of rotating force, cover portion gradually with the separation of product main part, observe red dial plate on the torsion bottle opener this moment, can know the size of product peeling force.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the structure is simple, and the manufacturing cost is low;

2. the test result is directly read through the dial plate, and is relatively intuitive;

3. the clamp can be adaptively replaced according to the shape of the stamping part, and is flexible to use.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The shielding case as shown in fig. 1 includes an outer frame body a and covering portions B and C, which are connected to each other through a plurality of circular holes D.

The peeling force measuring jig shown in fig. 2 and 3 is designed for the product in fig. 1, and includes a clamp 10, a slide rail 20, a base 30 and a torque dial wrench 40, wherein two bearing seats 50 are arranged in the base, a shaft rod 60 is installed in the two bearing seats, and the torque dial wrench is fixedly connected with the end of the shaft rod; the slide rail is arranged in the base, the guide direction of the slide rail is vertical to the central shaft of the shaft lever, and the clamp is connected to the slide rail in a sliding manner by adopting a slide block; the shaft rod is provided with a neck part 61 with a diameter smaller than that of the shaft rod corresponding to the clamp, a rope threading hole 62, preferably a strip hole, is arranged in the neck part, and a rope is threaded in the rope threading hole. Referring to fig. 4, the clamp comprises a clamp bottom plate 11, a cushion block 12, a first movable clamping block 13 and a second movable clamping block 14, wherein the cushion block 12 is fixed on the clamp bottom plate, one side of the movable clamping block is locked on the side face of the cushion plate, the second movable clamping block is fixed on the clamp bottom plate through a bolt 15, the cushion block is in a square design, and three first movable clamping blocks and two second movable clamping blocks are arranged on the periphery of the cushion block and can tightly press the stamping part on the cushion block.

Referring to fig. 5, the shielding case in fig. 1 is placed in a fixture for positioning and clamping, one end of a rope 90 is tied in a waist hole E connecting a covering part B and an outer frame body a, the fixture moves to the position right below a shaft rod through a sliding rail along with the rotation of a torque screwdriver, a waste material part is gradually separated from a product main body along with the increase of rotation force, and the size of the peeling force of the product can be known by observing a red dial on the torque screwdriver.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
