Description

Technical Field

[0001] This utility model belongs to the technical field of ultra-thick glass basins, and in particular relates to a tooling connection mechanism for fine polishing of ultra-thick glass basins. Background Technology

[0002] Glass washbasins are highly favored for their crystal-clear visual effect and excellent texture. Among them, extra-thick glass washbasins (usually referring to washbasins with a thickness of more than 15mm) have become the darling of the high-end bathroom market due to their heavy texture and excellent durability. However, after the extra-thick glass washbasins are formed, there will be imperfections such as burrs on their edges, inner walls, and bottom surfaces. In addition, due to the requirement of transparency, they must undergo high-precision polishing to achieve safe use standards and a mirror-like visual effect.

[0003] Currently, the industry mainly relies on robotic automation systems for polishing such irregular curved workpieces. This involves multi-degree-of-freedom industrial robots holding polishing heads and performing trajectory polishing on a basin fixed on a workstation. The key to achieving efficient and high-quality polishing lies in how to stably, reliably, and quickly clamp the basin onto the workstation.

[0004] Existing tooling solutions generally suffer from the following technical pain points: 1. The tooling structure is complex and has poor adaptability: In order to fix irregularly shaped washbasins, the common practice is to design a huge clamp or base that conforms to the outer contour of the washbasin. Such clamps are usually made of metal or composite materials, which are complex in structure, have high manufacturing costs, and occupy a lot of space. Moreover, a clamp is usually only suitable for a specific model of washbasin. Once the product is updated, the tooling needs to be redesigned and manufactured, which has extremely low flexibility. 2. Multiple clamping and positioning errors: Since the basin needs to be fully polished on its inner and outer surfaces and edges, the complex integral fixture often obscures part of the surface to be polished. Therefore, multiple clamping and flipping are usually required in production. Each re-clamping introduces new positioning errors, causing the polishing trajectory to deviate, which seriously affects the consistency of polishing quality and may even cause equipment collision accidents due to robot path errors.

[0005] 3. Risk of damaging the workpiece: Traditional chuck or pressure plate clamps usually clamp the visible decorative surface or fragile edge of the basin. Even with the addition of cushioning pads, there is still a risk of pinching, cracking the glass or leaving marks under the continuous vibration generated during the robot polishing process. For expensive ultra-thick glass basins, the loss of yield is huge.

[0006] 4. Interruptions in automated processes and low efficiency: Frequent workpiece flipping, disassembly, and reclamping heavily rely on manual operation, which not only results in high labor intensity but also prevents the entire automated polishing production line from operating continuously, becoming a bottleneck restricting the improvement of production efficiency.

[0007] Therefore, there is an urgent need in this field for a new tooling connection mechanism that can overcome the above-mentioned defects. It should have the characteristics of simple structure, strong versatility, accurate positioning, non-destructive clamping, and the ability to achieve rapid posture conversion, so as to truly unleash the potential of the robot polishing system. Summary of the Invention

[0008] The purpose of this utility model is to provide a tooling connection mechanism for fine polishing of ultra-thick glass basins. Through the design of the new connection mechanism, the complex and bulky contour base is eliminated. The clamping is achieved through the universal structure of the drain outlet. The structure is extremely compact, saves materials, and greatly reduces manufacturing costs. It is also highly adaptable to basins of different shapes and sizes, achieving adaptability to all situations and greatly improving the versatility and flexibility of the tooling.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a tooling connection mechanism for fine polishing of ultra-thick glass basins, including a basin body and a connection mechanism body. The basin body is provided with a drain outlet, and the connection mechanism body is installed at the drain outlet position of the basin body. The main body of the connecting mechanism includes an inner basin clamp and a bottom basin clamp; The basin-in clamp includes a lower seat plate with an annular structure. The top of the lower seat plate is integrally provided with a first step portion. A screw body is integrally provided on the first step portion. A first rigid sheath is fixed to the outside of the first step portion. The basin bottom clamp includes a threaded sleeve body that is threadedly engaged with the screw body. The bottom end of the threaded sleeve body is integrally provided with a washer ring. The bottom surface of the washer ring is integrally provided with a second step portion. A second rigid sheath is fixed to the outside of the second step portion. The lower seat plate of the basin clamp and the pad ring of the basin bottom clamp are both equipped with manual tightening parts, and the manual tightening parts are equipped with tooling connecting seats. The basin inner clamp and the basin bottom clamp are respectively installed inside the basin and at the bottom of the basin body. The first rigid sleeve and the second rigid sleeve are fitted and attached to the drain outlet.

[0010] Furthermore, the manual tightening component includes a set of uprights, the tooling connecting seat is fixed between the outer ends of the two uprights, and a stiffening plate is provided between the two uprights and the tooling connecting seat.

[0011] Furthermore, both ends of the tooling connector are provided with connection ports, and the connection ports are misaligned with the upright and stiffening plate.

[0012] Furthermore, the two uprights of the manual screw-on component of the basin bottom clamp are respectively connected to the washer, and the area of ​​the screw sleeve extending beyond the washer is misaligned with the uprights.

[0013] Furthermore, when the inner clamp and the bottom clamp are connected, a gap is formed between the rib plate of the bottom clamp and the screw body on the inner clamp.

[0014] Furthermore, after the inner clamp and the bottom clamp are connected, the second step of the bottom clamp fits into the first step of the inner clamp.

[0015] This utility model has the following beneficial effects: 1. This utility model, through the design of a novel connecting mechanism, abandons the complex and cumbersome contour base. The core consists of only two parts: the inner basin clamp and the bottom basin clamp. It uses the universal structure of the drain outlet for clamping, resulting in an extremely compact structure, saving materials and significantly reducing manufacturing costs. It is also highly adaptable to basins of different shapes and sizes (such as square, round, and oval). As long as the drain outlet specifications are the same or similar, it can be adapted by replacing the rigid sleeve of different sizes, achieving adaptability to all situations and greatly improving the versatility and flexibility of the tooling.

[0016] 2. This utility model, by setting manual tightening parts on the inner clamp and bottom clamp of the basin respectively, eliminates the need for additional tools, making it convenient for workers to operate. At the same time, it creatively realizes two process positionings with one physical clamping (tightening), which can stably polish the bottom surface, outer surface, inner wall and edge area of ​​the basin respectively. It avoids the cumbersome steps of completely removing the basin from the tooling and re-clamping it in the traditional process, greatly shortens the conversion time between the two polishing, and greatly improves the production cycle and the degree of automation of the entire line.

[0017] 3. By designing a novel connection mechanism, this utility model ensures that the basin body and the two clamps remain as a single unit throughout the polishing process, switching only between two preset, high-precision manual screw-in mounting ports. This minimizes the cumulative positioning error caused by repeated clamping. The robot programming can perform offset calculations based on the precise coordinate relationship between the two mounting ports, thereby ensuring that the polishing trajectory accurately covers the target curved surface whether it is the first or second positioning, effectively guaranteeing a high degree of consistency in the polishing quality of batch products.

[0018] This utility model installs the connecting mechanism at the drain outlet of the basin, and the clamping force is evenly applied to the inner and outer edges of the drain outlet. This part has high structural strength and is a non-decorative functional area. With the first and second hard protective sleeves (preferably engineering plastic or copper sleeves), it provides sufficient friction and perfectly avoids scratches, indentations or stress concentrations that may be caused by direct contact between the metal clamps and the glass surface, thus achieving non-destructive clamping and perfectly protecting the workpiece and equipment.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
