Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for manufacturing hydraulic supports, and particularly relates to an adjustable ear plate positioning device with a level gauge. Background Art

[0002] In a hydraulic support, the side guard plate of the top beam plays a role in lateral displacement and protection. During transportation, the side guard plate needs to be fixed on the top beam. Currently, the most commonly used fixing method is to weld ear plates on the top beam structural members and connect them at positions corresponding to the side guard plate of the top beam to ensure the smooth extension, contraction, and locking of the side guard plate. In the actual production process, the position of the ear plate is usually located by scribing or a simple tooling, with low efficiency. Moreover, during the assembly process of the support, the position of the ear plate is often inaccurate, resulting in misalignment or jamming, which affects the assembly. It is necessary to reposition and weld after trimming, affecting the production progress and customer satisfaction with the product.

[0003] There are currently two ways to place the ear plate. One is to place it on the top beam cover plate; the other is to place it on the outer side of the outer main rib plate. The problem of accurate positioning involves the positioning of the ear plates on the two outer main ribs of the top beam. As Figure 1 shown, for the ear plate of the side guard plate on the outer side of the outer main rib of the top beam of a certain type of support, its position is related to the top beam roof and the sleeve. It is necessary to ensure that the center of the ear plate hole is perpendicular to the roof and also ensure the horizontal dimension and spatial position with the sleeve. Scribing is difficult, and positioning is challenging. Ordinary tooling is made as a whole and is not universal. At the same time, for the positions of the ear plates on both sides, the tooling is symmetrically manufactured, increasing costs. Content of the Utility Model

[0004] The utility model overcomes the deficiencies of the prior art and provides an adjustable ear plate positioning device with a level gauge, which solves the problem of inaccurate positioning of the ear plates used for the side guard plate of the top beam on the current hydraulic support.
