Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pump processing, in particular to an automatic polishing production line for diaphragm pumps. Background Art

[0002] Diaphragm pumps, also known as control pumps, are a primary type of actuator. They utilize power to change fluid flow by receiving control signals from a control unit. They are a new type of conveying mechanism capable of transporting a variety of corrosive liquids, liquids containing particles, and high-viscosity, volatile, flammable, and highly toxic liquids. Their structural characteristics are the installation of rotating stainless steel pipe fittings on both sides of the pump body. When connecting multiple sections of pipe, these fittings must be connected using threads or flanges. Therefore, the connecting surfaces must be smooth, flat, and burr-free to ensure a tight and reliable connection.

[0003] In existing polishing operations, manual labor is typically used to initially smooth the product surface using a handheld grinder, followed by fine-grinding on a belt sander with varying mesh sizes from coarse to fine to ensure smooth, flat, and burr-free joints. However, manual polishing is time-consuming and labor-intensive, with low production capacity. The dust generated during polishing can damage the human respiratory tract. Furthermore, manual polishing cannot guarantee uniformity across a batch of products, potentially resulting in uneven polished surfaces and imperfect joints. Therefore, it is necessary to design an automated polishing device suitable for diaphragm pump components. Summary of the Invention

[0004] In view of this, the utility model provides an automatic polishing production line for a diaphragm pump to solve the above technical problems.

[0005] An automatic polishing production line for diaphragm pumps includes a silo, a robotic arm mounted on one side of the silo, a positioning fixture mounted on one side of the robotic arm, and a polishing mechanism mounted on one side of the robotic arm. A material tray is placed on the silo. The robotic arm's hand is equipped with a gripping assembly and a floating polishing assembly. The floating polishing assembly includes a connector connected to the robotic arm, a flange base mounted on the connector, a drilling and milling head mounted on the flange base, and a polishing head mounted on the flange base. The connector is a rotary switching head. The flange base is a fixed plate fixed to the connector. The drilling and milling head is an alloy grinding head mounted on a floating spindle. The polishing head is a grinding wheel polishing component with an air cooling element. The positioning fixture includes a placement table and a rotating table fixed to the placement table. The rotating table includes a rotating base plate, a first rotating mechanism mounted on the rotating base plate, a rotating cross plate connected to the first rotating mechanism, and a turntable mounted on the rotating cross plate. The first rotating mechanism includes a drive device fixed to the rotating baseplate and two rotating rings disposed between the rotating horizontal plate and the rotating baseplate. The rotating rings are connected to both ends of the rotating horizontal plate. The rotating horizontal plate is connected to the rotating baseplate via the rotating rings and is parallel to the bottom plate of the rotating baseplate. The turntable is located in the center of the rotating horizontal plate, and a rotating motor is located on the other side of the rotating horizontal plate.

[0007] Furthermore, the robot arm is arranged between the material bin, the positioning tooling table and the grinding mechanism.

[0008] Furthermore, the grabbing assembly and the floating grinding assembly are arranged on a rotating joint.

[0009] Furthermore, the drilling and milling head and the grinding head are oriented in opposite directions.

[0010] Furthermore, the placement table is a workbench with a Foma wheel provided at the bottom.

[0011] Furthermore, the grinding mechanism is a double-belt grinder, which is provided with two types of grinding belts with different mesh sizes.

[0012] Furthermore, the rotating base plate is a U-shaped structure, the bottom of which is fixed to the placement table by fasteners, and the two vertical plates extend vertically upward and are arranged parallel to each other.

[0013] Compared with the prior art, the automatic polishing production line for diaphragm pumps provided by the present invention realizes automatic grasping and polishing and deburring by setting the robot arm, which solves the need for manual polishing of products, helps to improve process standards and increase production efficiency. The floating polishing assembly is set on the robot arm to perform rough polishing on the product, thereby preventing differentiation caused by inaccurate product positioning or non-uniform product production, and ensuring the uniformity and flatness of the polished surface of the product. By setting the silo, multiple products are loaded in groups, and the silo has a larger storage capacity, which meets the loading requirements of mechanized operations and is compatible with multiple product models, helping to improve production efficiency. By setting the polishing mechanism and using sand belts of different mesh sizes, the process of replacing sand belts of different mesh sizes for polishing during fine polishing in the later stage is reduced, thereby speeding up the polishing speed and improving the polishing quality.
