Description

Technical Field

[0001] This utility model relates to the field of welding and grinding technology, and more specifically, to an automatic grinding machine for welded joints. Background Technology

[0002] Pressure vessels are mainly composed of numerous components, including the shell, heads, and nozzles, which are assembled and welded together. Among these, the shell is undoubtedly one of the most critical pressure-bearing components in a pressure vessel.

[0003] In the actual production process of pressure vessels, welding operations are frequently required on the end faces of two cylindrical components, or on the end faces of the cylinder and the head. After the welding of the two cylindrical components is completed, or after the welding of the cylinder and the head is completed, the next essential step is to grind the weld seams formed on the surface of the cylinder.

[0004] For grinding the longitudinal weld seams on smooth workpiece surfaces, such as square box containers, automatic grinding machines are typically used. This method significantly saves time and manpower, greatly improving work efficiency. However, it should be noted that the application of such automatic grinding machines currently has certain limitations; they are only suitable for workpieces with relatively small cylindrical diameters.

[0005] For surface grinding of longitudinal and circumferential welds on large-diameter cylindrical tubes, manual grinding is currently the most common method. Workers often need to use handheld grinding wheels to perform the grinding operation to meet the specific requirements of weld grinding. This manual grinding method is not only labor-intensive but also demands a high level of skill and experience from the workers. Prolonged handheld operation can easily lead to worker fatigue, potentially affecting the quality and precision of the grinding. Furthermore, manual grinding is relatively inefficient and difficult to meet the needs of large-scale production. Summary of the Invention

[0006] To address the problems of poor grinding quality, long processing time, low efficiency, and significant safety hazards in existing pressure vessel weld grinding processes, this invention provides an automatic weld joint grinding machine. The position of this automatic grinding machine can be freely adjusted according to the specifications and dimensions of the grinding cylinder to meet various grinding thickness requirements. Operators only need to control the control trolley buttons to adjust the cylinder rotation speed, and the grinding machine can grind the weld seam of the workpiece. This eliminates the hassle of manually rotating the cylinder, reduces labor intensity, improves work efficiency and grinding quality, and eliminates safety hazards during the grinding process.

[0007] The technical means adopted in this utility model are as follows:

[0008] An automatic grinding machine for welded joints includes: a grinding component, a drive component, a telescopic adjustable rod, and a fixing component;

[0009] The grinding assembly, drive assembly, and telescopic adjustable rod are respectively connected to the fixed assembly; the driven wheel in the grinding assembly has a wheel frame made of rubber; the drive wheel in the drive assembly has a specific surface roughness; and the cantilever bracket in the fixed assembly is made of stainless steel.

[0010] Furthermore, the driven wheel of the grinding assembly is assembled from a shaft, a bushing, and a baffle, and then welded to the fixing assembly.

[0011] Furthermore, the drive assembly consists of a drive wheel, a tension wheel, a motor, and a belt connected together to form an integral structure, and is bolted to the motor support. The motor support is welded to the fixing assembly.

[0012] Furthermore, the cylinder of the telescopic adjusting rod is bolted to the support, and a lug is welded to the bottom of the support, which is bolted to the fixing component.

[0013] Furthermore, the fixing component is a cantilever bracket, which is fixed to the external lifting platform of the equipment.

[0014] Furthermore, the motor in the drive assembly is an adjustable speed motor.

[0015] Furthermore, the extension stroke of the telescopic adjustable rod can be set and adjusted as needed.

[0018] 2. The automatic grinding machine for welded joints provided by this utility model has a cylinder and a support, a bottom lug of the support and a fixing component, and a Y-shaped joint of the cylinder telescopic adjustment rod and a driven wheel support plate bolted together. This facilitates installation, maintenance and adjustment, and can be flexibly adjusted according to different welded joint positions and shapes, thus improving the adaptability of the equipment.

[0019] 3. The automatic grinding machine for welding joints provided by this utility model adopts a cantilever bracket as the fixing component and is fixed on the external lifting platform of the equipment, so that the entire grinding machine can be adjusted in the vertical direction, which is convenient to adapt to welding joints of different heights and expands the application range of the equipment.

[0020] 4. The automatic grinding machine for welded joints provided by this utility model has an adjustable speed motor, which can adjust the speed according to different grinding needs and materials, so as to achieve more precise grinding control and improve grinding quality and efficiency.

[0021] 5. The automatic grinding machine for welded joints provided by this utility model has a telescopic adjustable rod whose extension stroke can be set and adjusted according to requirements, so that the equipment can adapt to welded joints of various sizes and shapes, improve the versatility and flexibility of the equipment, and reduce the equipment adjustment cost and time for workpieces of different specifications.
