Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot-rolled track steel quality inspection devices, in particular to a hot-rolled single-tooth track steel size measuring device. Background Art
[0002] Track steel is mainly used to make track chains of track-type excavators and is a consumable part. It is commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Single-tooth track steel is mainly used to make bulldozer track chains, which are used to build dumps, pile up scattered ore and rock, fill and dig covering materials, and carry out road construction. The construction conditions are harsh, and the strength, wear resistance and toughness of the track steel are high, and the size requirements are strict. Common track steel structures include Figure 3 As shown in Figure 2. Quality inspection of hot rolled track steel is a routine matter in industrial production.
[0003] In order to prevent the front and rear track steels from interfering during the operation of the track chain, tolerances are set for the long and short widths of the single-tooth track steel. During hot rolling production, the long and short widths of the single-tooth track steel teeth need to be measured. Figure 3 As shown, the long side width d1 is the distance from the end of the long side to the center line of the single tooth, and the short side width d2 is the distance from the end of the short side to the center line of the single tooth. The existing vernier calipers, inspection templates, etc. have many processes, are extremely inconvenient to operate, and are prone to human errors, resulting in deviations in the inspection results, making it difficult to meet the product quality inspection requirements under the existing production capacity, resulting in many problems in the size and quality of hot-rolled track steel.
[0004] In the prior art, it is difficult to measure with ordinary vernier calipers and inspection templates. When measuring with ordinary vernier calipers, the long side width and short side width of the single-tooth track steel do not have a position that can adapt to the clamping position of the claws, so the ordinary vernier caliper measures an inaccurate data; the inspection template only compares and fits the teeth and long and short sides with the template quickly, which can intuitively and quickly compare whether the long side and short side of the single-tooth track steel are qualified as a whole. The specific data of the long side width and the short side width cannot be objectively obtained, which affects the judgment of the steel size and cannot provide effective data support for the subsequent process changes. It is easy to produce scrap and affect production efficiency. Utility Model Content
