Description

Technical Field

[0001] This utility model belongs to the field of railway track wooden molds, specifically relating to an automatic detection and positioning tooling for turnout wooden molds. Background Technology

[0002] "Turnout molds" play a crucial role in railway engineering, particularly in turnout manufacturing. The core function of the turnout mold is to provide a precise physical prototype (master mold) that meets the process requirements for casting high-manganese steel turnouts. This prototype forms the casting cavity in the molding sand, ensuring the final cast turnout has the correct geometry, dimensional accuracy, and meets internal and external quality requirements. It is a critical bridge connecting design drawings and the actual casting, vital to the turnout's performance, lifespan, and operational safety. The precision of the mold is fundamental to ensuring that the casting's dimensional tolerances, surface quality, and the shape of key components (such as wheel flange grooves and rail top surfaces) meet requirements. A precise mold can minimize subsequent machining allowances in the casting, improving material utilization and production efficiency. Therefore, precise inspection of the mold is necessary during production. Currently, mold positioning relies entirely on manual operation, requiring frequent adjustments to maintain accuracy. Furthermore, with the widespread use of automated inspection methods, manual positioning is ill-suited to the current automated inspection processes. Summary of the Invention

[0005] Furthermore, a first gear is fixed to the output end of the second motor, and a second gear that meshes with the first gear is fixed to the transmission shaft located above the mounting housing. A second sliding frame with the same structure as the first sliding frame is fixed to the upper right side of the mounting housing.

A threaded positioning block 2-3 is fitted onto the threaded rod 2-1, and a balance block 2-4 is fixed to the positioning block 2-3.

For balance, two support rods 2-5 are also provided between the two facades 1-1 and on symmetrical sides of the threaded rod 2-1. The support rods 2-5 are fixedly connected to facades 1-1 and pass through the corresponding positions of the balance block 2-4, allowing the balance block 2-4 to slide horizontally along the support rods 2-5.

A sliding frame 3-1, which is a long, open-fronted box-shaped structure, is horizontally fixed to the right side of the mounting housing 3-7, and a first-order bidirectional threaded rod 3-2 is rotatably mounted inside. A fixing block 3-3 is fixed to the middle of the first-order sliding frame 3-1, and the first-order bidirectional threaded rod 3-2 passes through the fixing block 3-3. A support plate 3-4 for placing the wooden mold to be tested is provided at the front end of the fixing block 3-3; preferably, an anti-slip pad is provided on the support plate 3-4. The housing 3-7 contains a second motor 3-5 that drives the first bidirectional threaded rod 3-2. The first bidirectional threaded rod 3-2 has a threaded clamping head 3-6 installed on both the positive and negative threads. The rear end of the clamping head 3-6 is embedded in the first sliding frame 3-1, and the front end extends out of the first sliding frame 3-1 to clamp the wooden mold to be tested. When the second motor 3-5 drives the first bidirectional threaded rod 3-2 to rotate, the two clamping heads 3-6 can clamp and release along the first sliding frame 3-1.

[0016] To further enhance clamping stability, a first gear 4-1 is fixed to the output end of motor 3-5, and a second gear 4-2, meshing with the first gear 4-1, is fixed to the drive shaft 4-3 located on the upper part of the mounting housing 3-7.
