Description

Technical Field

[0001] This utility model relates to the field of metallurgical rotary joint technology, specifically a multi-angle grinding device for metallurgical rotary joint workpieces. Background Technology

[0002] Metallurgical rotary joints are rotary devices used in the metallurgical industry. They are mainly used to connect rotating and stationary components to achieve fluid or gas transmission. Metallurgical rotary joints are widely used in key parts such as the ladle turntable and sector section of continuous casting machines. Channel rotary joints can withstand pressures up to 250 bar and are used to transport media such as mineral oil, lubricating grease, air and argon. They can still ensure stable flow of molten steel and no leakage of media at a high temperature of 180 degrees Celsius. When processing metallurgical rotary joints, a multi-angle grinding device for metallurgical rotary joint workpieces is required.

[0003] Existing grinding equipment can only grind at fixed angles. For some complex-shaped rotary joint workpieces, it cannot fully meet the multi-angle grinding requirements, resulting in problems such as low grinding efficiency and difficulty in guaranteeing product quality.

[0006] Support legs fixedly installed at the bottom of the processing table;

[0007] And a grinding assembly located on the side of the processing table;

[0008] The polishing assembly includes a polishing mechanism disposed on the side of the processing table;

[0009] A stabilizing mechanism is provided at the top of the processing table.

[0010] Preferably, the grinding mechanism includes an adjusting block, which is slidably installed on the inner wall of the processing table with a groove. A connecting rod is slidably installed on the side wall of the adjusting block. A pull block is fixedly installed at one end of the connecting rod. A compression spring is fixedly installed on the side wall of the pull block. The other end of the compression spring is fixedly connected to the side wall of the adjusting block. An mounting block is fixedly installed on the top of the adjusting block. An L-shaped plate is rotatably installed on the inner wall of the mounting block via a bearing. A hydraulic cylinder is fixedly installed on the inner wall of the L-shaped plate. A motor is fixedly installed on the hydraulic cylinder via a hydraulic rod at its output end. A grinding wheel is fixedly installed on the motor via a rotating shaft at its output end. A second connecting block is fixedly installed on the top of the adjusting block. An electric push rod is hingedly installed on the inner wall of the second connecting block. A first connecting block is hingedly installed at the other end of the electric push rod. The top of the first connecting block is fixedly connected to the bottom of the L-shaped plate.

[0011] Preferably, a support block is slidably mounted on the bottom of the motor, and the bottom of the support block is fixedly connected to the top of the L-shaped plate. The support block can provide support for the bottom of the motor.

[0012] Preferably, one end of the plug-in rod extends movably through the inner wall of the adjusting block to the inner wall of the processing table. The diameter of the side wall of the plug-in rod is the same as the diameter of the inner wall of the circular groove on the side wall of the processing table. One end of the plug-in rod is slidably connected to the inner wall of the circular groove. When one end of the plug-in rod enters the inner wall of the circular groove, the position of the adjusting block can be limited.

[0013] Preferably, the stabilizing mechanism includes a stabilizing disk, which is fixedly installed on the top of the processing table. A U-shaped support block is fixedly installed on the top of the stabilizing disk, and a screw is installed on the inner wall of the U-shaped support block.

[0014] Preferably, the side wall of the screw is threadedly connected to the inner wall of the U-shaped support block, and a turntable is fixedly installed on the top of the screw.

[0015] Preferably, there are four support legs, all of which are of the same shape and size and are evenly distributed at the bottom of the processing table.

[0016] This utility model provides a multi-angle grinding device for metallurgical rotary joint workpieces. It has the following beneficial effects:

[0017] (1) This utility model allows the operator to adjust the position of the grinding wheel according to the size of the metallurgical rotary joint workpiece. The operator pulls the position of the pull block, which drives the compression spring and the insertion rod to move. When one end of the insertion rod is disengaged from the circular groove, the position of the adjustment block can be rotated. The adjustment block can slide on the inner wall of the slide groove on the inner wall of the processing table to quickly adjust the angle of the grinding wheel. The operator can also open the hydraulic cylinder, which drives the support block and the grinding wheel to adjust their positions. The operator can also open the electric push rod, which drives the position of the connecting block to move. The connecting block drives the L-shaped plate to rotate on the inner wall of the mounting block to further adjust the angle of the grinding wheel. The motor can drive the grinding wheel to rotate, which can perform multi-angle grinding on the metallurgical rotary joint workpiece. This solves the problem that the existing grinding device can only grind at a fixed angle. For some complex-shaped rotary joint workpieces, it cannot fully meet the multi-angle grinding needs, resulting in low grinding efficiency and difficulty in guaranteeing product quality.

[0018] (2) In this utility model, the operator places the metallurgical rotary joint workpiece on the top of the stabilizing plate, and then the turntable can be rotated directly. The turntable drives the position of the screw to rotate. Since the side wall of the screw is threadedly connected to the inner wall of the U-shaped support block, when the screw rotates, it can drive the position of the pressure plate to drop, so that the bottom of the pressure plate contacts the metallurgical rotary joint workpiece, effectively stabilizing the position of the metallurgical rotary joint workpiece.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the multi-angle grinding device for metallurgical rotary joint workpieces provided by this utility model is as follows: Figures 1 to 4 As shown: A multi-angle grinding device for metallurgical rotary joint workpieces, including a processing table 1,

[0026] The support legs 2 are fixedly installed at the bottom of the processing table 1. There are four support legs 2, and the four support legs 2 are all the same in shape and size. The four support legs 2 are evenly distributed at the bottom of the processing table 1.

[0027] And a grinding assembly 4 located on the side of the processing table 1;

[0028] The grinding assembly 4 includes a grinding mechanism 41 disposed on the side of the processing table 1;

[0029] A stabilizing mechanism 42 is provided at the top of the processing table 1.

[0030] The grinding mechanism 41 includes an adjusting block 411, which is slidably installed on the inner wall of the processing table 1 where a groove is formed. A connecting rod 414 is slidably installed on the side wall of the adjusting block 411. A pull block 412 is fixedly installed at one end of the connecting rod 414. A compression spring 413 is fixedly installed on the side wall of the pull block 412. The other end of the compression spring 413 is fixedly connected to the side wall of the adjusting block 411. An mounting block 416 is fixedly installed on the top of the adjusting block 411. An L-shaped plate 417 is rotatably mounted on the inner wall of the mounting block 416 via a bearing. A hydraulic cylinder 419 is fixedly installed on the inner wall of the L-shaped plate 417. A motor 4110 is fixedly installed on the hydraulic cylinder 419 through the hydraulic rod at the output end. A grinding wheel 4111 is fixedly installed on the motor 4110 through the rotating shaft at the output end. A connecting block 2 4113 is fixedly installed on the top of the adjusting block 411. An electric push rod 4112 is hinged to the inner wall of the connecting block 2 4113. A connecting block 1 415 is hinged to the other end of the electric push rod 4112. The top of the connecting block 1 415 is fixedly connected to the bottom of the L-shaped plate 417.

[0031] In this embodiment, a support block 418 is slidably mounted on the bottom of the motor 4110. The bottom of the support block 418 is fixedly connected to the top of the L-shaped plate 417. The support block 418 can support the bottom of the motor 4110.

[0032] Furthermore, one end of the plug rod 414 extends movably through the inner wall of the adjusting block 411 to the inner wall of the processing table 1. The diameter of the side wall of the plug rod 414 is the same as the inner wall diameter of the circular groove on the side wall of the processing table 1. One end of the plug rod 414 is slidably connected to the inner wall of the circular groove. When one end of the plug rod 414 enters the inner wall of the circular groove, the position of the adjusting block 411 can be limited.

[0033] In practice, the operator adjusts the position of the grinding wheel 4111 according to the size of the metallurgical rotary joint workpiece. The operator also pulls the pull block 412, which moves the compression spring 413 and the insertion rod 414. When one end of the insertion rod 414 disengages from the circular groove, the adjusting block 411 can rotate. The adjusting block 411 can slide along the inner wall of the groove on the inner wall of the processing table 1, quickly adjusting the angle of the grinding wheel 4111. The hydraulic cylinder 419 is activated, which drives the support block 418 and the grinding wheel 4111 to adjust their positions. The operator can also activate the electric push rod 4112, which drives the connecting block 415 to move. The connecting block 415 drives the L-shaped plate 417 to rotate on the inner wall of the mounting block 416, further adjusting the angle of the grinding wheel 4111. The motor 4110 can drive the grinding wheel 4111 to rotate, enabling multi-angle grinding of the metallurgical rotary joint workpiece.

[0034] Example 2: Based on Example 1, a preferred embodiment of the multi-angle grinding device for metallurgical rotary joint workpieces provided by this utility model is as follows: Figures 1 to 4 As shown: The stabilizing mechanism 42 includes a stabilizing disk 421, which is fixedly installed on the top of the processing table 1. A U-shaped support block 422 is fixedly installed on the top of the stabilizing disk 421. A screw 423 is installed on the inner wall of the U-shaped support block 422. A pressure plate 425 is rotatably installed on the bottom of the screw 423 through a bearing.

[0035] In this embodiment, the side wall of the screw 423 is threadedly connected to the inner wall of the U-shaped support block 422, and a turntable 424 is fixedly installed on the top of the screw 423.

[0036] In the specific implementation process, the operator places the metallurgical rotary joint workpiece on the top of the stabilizing plate 421, and then directly rotates the turntable 424. The turntable 424 drives the position of the screw 423 to rotate. Since the side wall of the screw 423 is threadedly connected to the inner wall of the U-shaped support block 422, when the screw 423 rotates, it can drive the position of the pressure plate 425 to drop, causing the bottom of the pressure plate 425 to contact the metallurgical rotary joint workpiece, effectively stabilizing the position of the metallurgical rotary joint workpiece.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
