Description

Adjustable positioning device for glass cutting table

Technical field:

The utility model relates to a glass cutting table in a flat glass processing machine, in particular to a positioning device for table glass in the glass cutting table.

Background technique:

The most traditional flat glass cutting is manual operation with glass knife and ruler, which not only has high labor intensity, low efficiency, but also low cutting precision. With the rapid development of economic construction, the consumption of cutting glass is increasing, and the requirement of cutting precision is getting higher and higher. Manual cutting glass can no longer meet the above requirements. In response to this, a motor-driven double-bridge automatic cutting table has appeared in recent years, and a group of knife boxes with alloy steel knife wheels are respectively connected to the double bridges, so that the work efficiency is doubled. But, the location of its desktop glass generally adopts that fixed positioning blocks are set at the edge of the desktop to realize the positioning of the table glass. However, such a problem often occurs in actual use, that is, the cutter wheel for cutting glass just needs to cut the knife from the positioning block. Therefore, a section of glass close to the positioning block cannot be cut by the cutter wheel, so that the cut glass There will be quality defects such as beveled edges and broken edges. Extensive searches have been carried out for the above problems, but no relevant product or technical literature has been found.

Invention content:

The purpose of this utility model is exactly to solve the defect existing in the prior art, and a kind of adjustable positioning device of design solves the problem of positioning and lowering the knife.

In order to achieve the above object, the utility model adopts the following technical solutions:

An adjustable positioning device for a glass cutting table, which is composed of a frame, a slide rail connected to the frame, and a tabletop. The slide rail is connected with an orthogonal crossbeam, and a knife rest is arranged on the crossbeam. The adjacent two sides are respectively connected with a guide rail with a concave cross section, and a set of sliders matching the concave groove are arranged in the concave groove of each guide rail, and a matching screw is connected in the screw hole of each slider. A locking positioning sleeve is connected to each screw to cooperate with the surface of the guide rail to realize locking and positioning. The cross-sectional shape of the guide rail and the slider is rectangular, or other shapes such as trapezoid. The locking and positioning sleeve can be made of metal, or nylon and other materials, and a metal bush can be connected to the nylon locking and positioning sleeve, and the screw can be connected and matched with the bush.

Due to the adoption of the above technical solution, the locking and positioning device provided by the utility model can be easily adjusted along the guide rail and lock the positioning position, thus completely solving the problem of interference between the positioning device and the cutter wheel, and avoiding the The quality defects such as beveled edges and broken edges in the cut glass have greatly improved the product quality.

In order to illustrate the utility model in more detail, the following drawings provide a preferred embodiment of the utility model.

Description of drawings:

Fig. 1 is the top view of the utility model;

Fig. 2 is A-A sectional view of Fig. 1;

Detailed ways:

As shown in Fig. 1, the utility model is mainly made up of frame 5 and desktop 1, and frame 5 and desktop 1 are formed, and a pair of vertical slide rail 2 and a pair of horizontal slide rail 7 are respectively connected around frame 5, vertically The slide rail 2 and the transverse slide rail 7 are connected with the longitudinal beam 4 and the transverse beam 9 respectively, and the longitudinal beam 4 and the transverse beam 9 are equipped with the knife rest 8 and the knife rest 10 respectively, and the knife rest 8 and the knife rest 10 follow the longitudinal beam 4. The transverse beam 9 moves orthogonally along the slide rails 2 and 7, and the cutter wheels installed on the cutter rests 8 and 10 will cut the glass 1a fixed on the desktop 1 into shape. In the utility model, a guide rail 3 and 11 with a concave cross-section is respectively installed on the adjacent two sides of the inner side of the desktop 1, and three (any number) locking and positioning devices 6 are respectively arranged in each guide rail, and its specific structure is shown in the figure 2, a rectangular sliding block 6d with loose fit is set in the concave groove of the guide rail 3, a hexagon socket head screw 6a is connected in the screw hole in the sliding block 6d, and a nylon locking positioning sleeve 6c is arranged on the top of the guide rail 3, wherein Then connect a metal bushing 6b, and the cap head of the inner hexagonal screw 6a cooperates with the bushing and the locking positioning sleeve. The working process of the utility model is as follows: unscrew the screw 6a, move and adjust the nylon locking positioning sleeve 6c to a suitable position, tighten the screw 6a, and make the nylon locking positioning sleeve through the clamping action of the slider 6d and the inner cavity of the concave groove of the guide rail. 6c is fixedly positioned with the guide rail 3, and the left end of the glass 1a to be processed is positioned against the nylon locking positioning sleeve 6c.
