Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of RGV positioning, in particular to a flexible positioning mechanism of an RGV trolley. Background Art
[0002] Bogie maintenance often requires cleaning mud, oil, paint, and other debris from both sides, requiring the bogie to be flipped. Current flipping mechanisms often rely on manually adjusted clamps, which is time-consuming and labor-intensive, and because manual locking is required, safety cannot be guaranteed. RGVs, also known as rail-guided vehicles, can be used in various industries such as production, logistics, and foundry. They can move workpieces between multiple processing stations, improving efficiency. To improve bogie cleaning efficiency, a laser cleaning mechanism and RGV trolley are often combined to form a cleaning production line. Laser cleaning mechanisms have high processing precision, requiring guaranteed positioning accuracy.
[0003] Because the top and bottom structures of the bogie are different and asymmetrical, it is difficult to secure it after flipping it over. The bogie fixture often needs to be repositioned after flipping, which is time-consuming and labor-intensive. Furthermore, bogies come in a wide variety of sizes, making it difficult to adapt the flipping mechanism fixture to all bogies.
[0004] In addition, the RGV trolley is also prone to displacement during movement or flipping. Therefore, a positioning mechanism that can meet the needs is urgently needed. Utility Model Content
[0005] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively proposes a flexible positioning mechanism for the RGV trolley, which is suitable for bogies of different specifications and can be positioned during flipping to avoid the workpiece from being offset during movement or during the process of taking and placing the workpiece on the tooling.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a flexible positioning mechanism for an RGV trolley, including a tooling arranged on the RGV trolley, the tooling being used to place a bogie, a plurality of support columns being vertically arranged on the top of the tooling, and a positioning sleeve corresponding to the spring seat of the bogie, the positioning sleeve being used to be sleeved on the spring seat of the bogie, the number of the support columns being consistent with the number of the positioning sleeves, positioning grooves being correspondingly arranged on the top and bottom of the positioning sleeves, a positioning protrusion matching the positioning groove being provided on the top of the support column, a clamping positioning convex point being provided on the front side of the front positioning sleeve for positioning the clamping tooling of the flipping mechanism, and a clamping positioning convex point being provided on the rear side of the rear positioning sleeve for positioning the clamping tooling of the flipping mechanism.
[0007] In the above solution: an adjustment mechanism is provided on the tooling corresponding to each support column.
[0008] In the above solution: the adjustment mechanism is a linear bearing adjuster, and the support column is fixedly installed on the adjustment mechanism, and the position of the support column can be adjusted according to the position of different bogie spring seats.
[0009] In the above solution, the positioning groove is a raised ring provided at the bottom of the positioning sleeve, with the central area surrounded by the raised ring forming the positioning groove. The positioning protrusion is a frustum that matches the positioning groove. This provides a simple structure, and the frustum-shaped positioning protrusion can be automatically aligned.
[0010] In the above solution: the clamping and positioning protrusion is cylindrical extending forward and backward.
[0011] In summary, the beneficial effects of the present invention are as follows: the provided tooling is used to place the bogie, and is used in combination with the RGV trolley to drive the bogie to different processing equipment for processing, and the provided support column is used to support the workpiece. The provided positioning sleeve is used to be pre-mounted on the bogie, and can directly use the spring seat to press against the inside of the sleeve hole of the positioning sleeve, thereby achieving the installation and fixation of the positioning sleeve. At the same time, the provided positioning sleeve can also be applied to bogies of different models and spring seats in different positions, thereby increasing the scope of application. The positioning grooves provided at the top and bottom correspond to each other, so that they can directly correspond when supported by the support column, ensuring that the workpiece is in the same position each time the workpiece is placed or taken out, avoiding errors and improving processing accuracy. The provided positioning protrusion is used for the clamping tooling of the flipping mechanism to clamp and position, facilitating the clamping tooling of the flipping mechanism to clamp without contacting the bogie, thereby eliminating the need to set different clamping tools for the corresponding bogies, facilitating the flipping of the bogie to meet the flipping requirements of bogies of different specifications, and having a wide range of applications.
