Worm gear copper-based bedplate thread lockpin circular plywood glass detection device

Abstract

The invention relates to a tempered glass detection device, in particular to a worm gear copper-based bedplate thread lockpin circular plywood glass detection device. Improvement is conducted, a drive worm gear is further fixed on a bedplate rotating shaft on one side and matched with a worm shaft, the two ends of the worm shaft are rotatably fixed in a worm support which is fixed on the outer side face of the corresponding plate type rack, and one end of the worm shaft is further provided with a worm crank handle; a stud lockpin external thread is matched with a lockpin support inner hole thread, and cylindrical ball heads of stud lockpin ends at the two sides can enter spiral cone column lockholes in the two sides of a test bedplate for locking positioning; a circular rail slideway plywood assembly is fixed on the plane of the test bedplate, a middle pull rod in the front of the rack is arranged between an upper pull rod in the front of the rack and a lower pull rod in the front of the rack, and a broken glass recycling container is fixed on the middle pull rod in the front of the rack, the upper pull rod in the front of the rack and an upper pull rod on the rear of the rack; by means of the circular rail slideway plywood assembly, continuously random adjustment can be conducted on the tempered glass board with different specifications and dimensions.

Description

technical field [0001] The present invention relates to a tempered glass inspection instrument, in particular to such a round splint glass inspection apparatus which can be enlarged or reduced around the splint and uses a reversible workbench to test the strength of the glass. Background technique [0002] Fragmentation test is a main way to detect the quality of tempered glass. According to the requirements of national standards, after the 3mm thick tempered glass is broken, the fragments in any 50*50mm should be more than 30 pieces, and the 4mm~12mm thick tempered glass is broken. Fragments within any 50*50mm should be larger than 40 pieces, and a small amount of long fragments are allowed, the length of which should not exceed 75mm. The direction of the strip-shaped fragments should be roughly parallel to the edge of the glass. If they are not parallel, the included angle should not exceed 45 degrees. If one item fails to meet the standard, it is a substandard product. ...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device

[0004] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0005] China's other patent application number: 201420595067.X, tempered glass shard state test device, proposed some new methods and measures to deal with brittle glass splints, but it is still impossible to adjust any size, and it is impossible to make the four sides of the splints all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
