Description

Technical Field

[0001] The present application relates to the technical field of grinding of large-diameter titanium cylinders after welding, and in particular to a grinding device for welding points of flanges of large-diameter titanium cylinders. Background Art

[0002] Titanium cylinder refers to a cylindrical structure made of titanium or titanium alloy. Titanium is a high-performance metal material with the advantages of light weight, high strength, and strong corrosion resistance. Therefore, titanium cylinders are widely used in various occasions that require high strength and corrosion resistance, including the chemical industry: titanium cylinders can withstand the erosion of various strong acids, strong alkalis and other corrosive media, so they are widely used in the chemical industry to manufacture reactors, storage tanks, pipelines and other equipment; marine engineering: such as the manufacture of seawater desalination equipment, offshore oil exploration equipment, etc.; medical field: such as the manufacture of artificial joints, dental implants and other medical devices. Titanium cylinders have received widespread attention and application in various fields due to their excellent performance and broad application prospects.

[0003] The titanium cylinders currently used in the chemical industry usually have larger dimensions (such as cylinder length and inner diameter), so that reactors can accommodate more reaction solutions at a time to improve operating efficiency. Reactors or other similar titanium cylinder containers usually need to be associated with upstream and downstream processes, so the ports of the titanium cylinders need to be connected. The usual sealing connection method is to weld flange connection plates at the ports of the titanium cylinders and connect them with bolts, which can achieve rapid connection operations of the titanium cylinders, while also ensuring connection strength and sealing, and is widely used in the field of pipeline connections.

[0004] At present, in order to improve the surface quality of the titanium cylinder after welding it to the flange, it is necessary to grind the welding joints between the two. For titanium cylinders with smaller inner diameters, it is relatively easy to grind. However, for titanium cylinders with larger diameters, manual grinding is more difficult, which will affect the grinding quality of the welding joints. Excessive grinding will also cause damage to the cylinder or flange, and the grinding efficiency is low. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a grinding device for the welding points of large-diameter titanium cylinder flanges, which solves the current difficulty in manual grinding of large-diameter titanium cylinders by supporting and adjusting the grinding equipment, thereby improving the grinding efficiency and grinding quality.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a grinding device for a large-diameter titanium cylinder flange welding point, characterized in that: the grinding device is placed on the ground, and includes an adjustment mechanism extending into the inner cavity of the cylinder and close to the welding point between the cylinder and the flange, and a grinding device that can contact the welding point between the cylinder and the flange is also arranged on the adjustment mechanism.

[0007] Preferably, the grinding device comprises a base, the adjustment mechanism comprises a vertical adjustment rod vertically arranged on the base, a horizontal adjustment rod is arranged at the top end of the vertical adjustment rod, and the grinding equipment is assembled at the end of the horizontal adjustment rod.

[0008] Preferably, the vertical adjustment rod comprises a threaded barrel rotatably disposed on the base, and a screw rod fixed to the end of the horizontal adjustment rod and passing through the threaded barrel.

[0009] Preferably, the grinding device is detachably hinged to the end of the horizontal adjustment rod, and the hinge point of the grinding device is adjustable and lockable.

[0010] The beneficial effect of the present application is that the grinding device can support the grinding equipment that is currently manually held and lifted, and at the same time accurately adjust the grinding equipment to connect with the welding point between the titanium cylinder and the flange, thereby performing labor-saving and precise grinding operations, solving the current operational difficulty of manual grinding of large-diameter titanium cylinders, and thereby improving the grinding efficiency and grinding quality.

[0020] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See attached Figures 1 to 8 The device for grinding the welding point of a large-diameter titanium cylinder flange is shown. The grinding device is placed on the ground and includes an adjustment mechanism that extends into the inner cavity of the cylinder 1 and is close to the welding point between the cylinder 1 and the flange 2, and a grinding device that can contact the welding point between the cylinder 1 and the flange 2 is also arranged on the adjustment mechanism. The titanium cylinder is axially placed at the welding point when grinding. Figure 4 On the roller base 7 shown in the figure, the titanium cylinder can be driven by external force or roller drive to rotate in the circumferential direction. When the titanium cylinder is in a rotatable state, the grinding device is driven close to the outer port of the titanium cylinder, and the grinding equipment (preferably a hand-held grinder 6) is driven by the adjustment mechanism to contact the welding point between the cylinder and the flange. The grinding equipment can perform precise grinding operations, which solves the difficulty of manual grinding of large-diameter titanium cylinders at present, thereby improving the grinding efficiency and grinding quality.

[0022] Specifically, Figure 5 As shown, the grinding device includes a base 3, and the adjustment mechanism includes a vertical adjustment rod 4 vertically arranged on the base 3, which can adjust the vertical height. A horizontal adjustment rod 5 is arranged at the top of the vertical adjustment rod 4, which can adjust the horizontal length. The grinding equipment is assembled at the end of the horizontal adjustment rod 5, and the contact between the grinding head of the grinding equipment and the welding point of the titanium cylinder and the flange can be adjusted by the vertical adjustment rod 4 and the horizontal adjustment rod 5. The grinding operation can be performed when the grinding head of the grinding equipment rotates at a high speed. At the same time, through the circumferential rotation of the titanium cylinder, continuous grinding operation is also performed along the circumferential welding seam of the titanium cylinder and the flange.

[0023] Preferably, a lockable driving wheel 31 is provided at the bottom of the base to facilitate the overall transfer operation of the grinding device.

[0024] Preferably, Figure 5 As shown, the vertical adjustment rod 4 includes a threaded barrel 41 rotatably arranged on the base 3, and a screw 42 fixed to the end of the horizontal adjustment rod 5 and inserted into the threaded barrel 41. The grinding device can be adjusted vertically by rotating the threaded barrel 41, and the grinding depth can be precisely adjusted. The screw 42 is sleeved with a locking nut 9 to lock the height of the vertical adjustment rod 4 after adjustment. At the same time, preferably, as Figure 5As shown, the horizontal adjustment rod 5 is a telescopic rod structure with an inner and outer structure, and is provided with an adjustable locking pin hole (not shown in the figure), which can quickly adjust the axial position of the grinding device. After adjusting the position of the grinding device, the titanium cylinder is slowly driven to rotate, and the circumferential continuous grinding operation can be achieved through the height rotation of the grinding head of the grinding device. In actual operation, the operator can hold the horizontal adjustment rod 5 on the outside of the titanium cylinder to further improve the stability during the grinding process and overcome the rotation of the vertical adjustment rod 4.

[0025] When the titanium cylinder has a conical structure section and the position forming an angle with the flange needs to be ground, such as Figure 8 As shown, the grinding device is detachably hinged at the end of the horizontal adjustment rod 5, and the hinge point of the grinding device can be adjusted and locked. Preferably, the hinge between the grinding device and the horizontal adjustment rod 5 is hinged with a screw. After the grinding head of the grinding device is adjusted to fit the angle structure between the titanium cylinder and the flange, it can be locked by the screw 8 to ensure the stability of the adjustment angle of the grinding device, so that the grinding operation at the welding point with an angle can be realized, thereby improving the applicability of the grinding device.

[0026] The principle of the present application is: when performing the grinding operation on the welding point between the titanium cylinder and the flange or the inner wall of the titanium cylinder, the titanium cylinder is first placed axially on the roller base, and then the grinding device is moved close to the port of the titanium cylinder through the movable base and locked, and then the grinding head of the grinding device is driven to connect with the welding point between the titanium cylinder and the flange through the vertical adjustment rod 4 and the horizontal adjustment rod 5 (at the same time, the grinding angle of the grinding head can be adaptively adjusted), the grinding device is started and rotated slowly and uniformly, and the circumferential continuous grinding operation of the welding point between the titanium cylinder and the flange can be performed.

[0027] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
