Description

Technical Field

[0001] This invention relates to the field of workpiece grinding technology, specifically a grinding machine tool that can automatically adapt to grinding pressure. Background Technology

[0002] As a flow guiding device, the pipe body is frequently used in both industry and daily life. When it is necessary to connect two pipe bodies to increase the service length, welding is usually used to connect the two pipe bodies. After the two pipe bodies are welded, the weld scars at the weld joint need to be ground.

[0003] Currently, most weld scars are ground manually. When grinding weld scars on pipes made of different materials, the grinding pressure depends entirely on the operator's experience, resulting in inconsistent grinding quality. In addition, for pipes with larger diameters, it is difficult to turn the pipe over, which is even more detrimental to the worker's grinding work, thus reducing the efficiency of grinding weld scars on pipes.

[0021] Please see Figure 8 The control mechanism 3 includes four L-shaped angle irons 301 that are symmetrically arranged in pairs and fixedly connected to the first mounting plate 201.

A plug rod 306 is fixedly connected to the side of each fourth mounting plate 305 near the counterweights 302. Multiple plug holes 307 are opened on the side wall of each counterweight 302. Each plug hole 307 is matched with the plug rod 306. It should be noted here that by setting the control mechanism 3, the grinding pressure of the grinding head 203 can be controlled so that the grinding feed rate matches the material of the pipe 102, thereby improving the quality of grinding the weld scars on the pipe 102 and avoiding damage to the grinding blade 204 caused by the excessive feed speed of the grinding head 203.

[0022] Please see Figure 8Each third mounting plate 303 is provided with a pushing mechanism 4 for pushing the insertion rod 306.

It should be noted that by setting up the pushing mechanism 4, under the magnetic action of the electromagnet 401, the iron block 402 on the fourth mounting plate 305 will be attracted, thereby pushing the insertion rod 306 on the fourth mounting plate 305 into the insertion hole 307 on the counterweight block 302. In actual use, the number of counterweight blocks 302 applied to the second mounting plate 207 can be selected according to the material of the pipe 102.

[0023] Please see Figure 2 The base plate 101 is provided with a drive mechanism 5 for driving the first mounting plate 201. The drive mechanism 5 includes two drive tubes 501 that are fixedly connected to the base plate 101 and arranged symmetrically. A drive rod 502 is slidably connected to one of the two drive tubes 501. One end of the drive rod 502 is connected to the first mounting plate 201. A threaded rod 503 is threadedly connected to the other of the two drive tubes 501. A second motor 504 is provided on the first mounting plate 201. The output end of the second motor 504 is connected to the threaded rod 503. It should be noted here that the drive mechanism 5 facilitates the movement of the grinding head 203.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The first mounting plate 201 is provided with a detection mechanism 6 for detecting the moving distance of the grinding head 203. The detection mechanism 6 includes two symmetrically arranged detection tubes 601 fixedly connected to the side of the first mounting plate 201 near the pipe 102. The two detection tubes 601 are symmetrically arranged about the grinding head 203. The other ends of the two detection tubes 601 are rotatably connected to a first rotating ball 602. The two first rotating balls 602 are at the same horizontal position as the grinding blade 204. A first fixing plate 603 is fixedly connected to the side wall of the first mounting plate 201. An image sensor 604 is provided on the first fixing plate 603. The image sensor 604 is arranged opposite to the first rotating ball 602. It should be noted here that: by setting up the detection mechanism 6, when the first rotating ball 602 on the detection tube 601 abuts against the side wall of the pipe 102, the rotation of the second motor 504 will be stopped under the detection action of the image sensor 604, thereby realizing the control of the grinding allowance of the grinding head 203.

[0025] Please see Figure 5 and Figure 6 The first mounting plate 201 is provided with a rotating mechanism 7 for rotating the pipe 102. The rotating mechanism 7 includes a second fixed plate 701 fixedly connected to the side wall of the first mounting plate 201. A first rotating shaft 702 is rotatably connected to the second fixed plate 701. A first bevel gear 703 is fixedly connected to the end of the first rotating shaft 702 near the first motor 208. A second bevel gear 704 is fixedly connected to the side wall of the rotating rod 206. The second bevel gear 704 and the first bevel gear 703 are meshed with each other. A U-shaped plate 705 is fixedly connected to the side of the second fixed plate 701 away from the first mounting plate 201. A second rotating shaft 706 is rotatably connected to the side of the U-shaped plate 705 away from the first mounting plate 201. A rotating disk 707 is fixedly connected to the end of the second rotating shaft 706 away from the first rotating shaft 702. The rotating disk 707 and the first rotating ball 602 are on the same horizontal line. The other end of the second rotating shaft 706 is connected to the first rotating shaft 702 through a universal joint transmission rod 708. It should be noted that, through the setting of the rotating mechanism 7, after the grinding head 203 has finished grinding the weld scars in the area, the rotating disk 707 will abut against the side wall of the pipe 102. Under the rotation of the rotating disk 707, the pipe 102 will be rotated. This not only avoids the grinding head 203 from excessively grinding the weld scars of the pipe 102, but also realizes the automatic rotation of the pipe 102, thereby improving the quality and efficiency of grinding the weld scars of the pipe 102.

[0026] Please see Figure 4 and Figure 7 The first mounting plate 201 is provided with a cooling mechanism 8 for cooling the grinding head 203. The cooling mechanism 8 includes an L-shaped tube 801 fixedly connected to the first mounting plate 201. A mounting ring 802 is fixedly connected to one end of the L-shaped tube 801 near the grinding head 203. The mounting ring 802 is concentrically arranged with the grinding head 203. A plurality of inclined cooling ports 803 are opened on the inner wall of the mounting ring 802. Each cooling port 803 is arranged opposite to the grinding head 203. It should be noted that the cooling mechanism 8 facilitates the cooling of the grinding blade 204 on the grinding head 203, thereby helping to improve the grinding quality and reduce the wear of the grinding blade 204.

[0027] Please see Figure 7 A control switch 10 is provided on the side wall of the L-shaped tube 801; It should be noted here that the setting of control switch 10 facilitates the control of the cooling system's on and off states.

[0028] Please see Figure 5The side wall of the grinding head 203 is provided with multiple inclined fan blades 9; It should be noted here that the design of fan blade 9 facilitates the blowing away of dust that has been ground off the weld spatter.

[0029] Please see Figure 1 The base plate 101 is provided with an installation mechanism 11 for installing the pipe 102. The installation mechanism 11 includes two symmetrically arranged fifth installation plates 1101 fixedly connected to the base plate 101. The fifth installation plate 1101 is provided with a three-jaw chuck 1102. The three clamping rods 1103 on the three-jaw chuck 1102 are rotatably connected to the opposite ends of a second rotating ball 1104. It should be noted that the three-jaw chuck 1102 is existing technology and will not be described in detail here.

[0030] It should be noted that, through the installation mechanism 11, when it is necessary to grind the weld scars at the welded joint of the pipe 102, both ends of the pipe 102 are clamped and fixed by the three-jaw chuck 1102 on the fifth mounting plate 1101. Since the two ends of the three clamping rods 1103 are rotatably connected to the second rotating ball 1104, the pipe 102 can still rotate after it is clamped and fixed.

[0031] Working principle: When it is necessary to grind the weld scars at the welded joint of pipe 102, both ends of pipe 102 are clamped and fixed by the three-jaw chuck 1102 on the fifth mounting plate 1101. Since the two ends of the three clamping rods 1103 are rotatably connected to the second rotating ball 1104, pipe 102 can still rotate after being clamped and fixed. After the pipe 102 is clamped and fixed using the three-jaw chuck 1102, the second motor 504 is started, which drives the threaded rod 503 to rotate. Under the threaded meshing transmission between the threaded rod 503 and the drive tube 501 and the guiding action of the drive rod 502, the first mounting plate 201 is driven to move closer to the pipe 102. During the process of the first mounting plate 201 moving closer to the pipe 102, the grinding head 203 on the second mounting plate 207 will be driven to move closer to the pipe 102 simultaneously. Furthermore, when grinding the welding torch on the pipe 102, the pressure applied to the grinding head 203 can be selected according to the material of the pipe 102. When the pressure is applied to the grinding head 203, the electromagnet 401 is energized. Under the magnetic action of the electromagnet 401, the iron block 402 on the fourth mounting plate 305 will be attracted, thereby pushing the insertion rod 306 on the fourth mounting plate 305 into the insertion hole 307 on the counterweight block 302. In actual use, the number of counterweight blocks 302 applied to the second mounting plate 207 can be selected according to the material of the pipe 102. As the second motor 504 continues to rotate, it drives the grinding head 203 to move closer to the pipe 102. During this movement, the first motor 208 is activated, causing the grinding blade 204 at one end of the grinding head 203 to rotate. As the grinding head 203 continues to move closer to the pipe 102, when the grinding blade 204 on the grinding head 203 comes into contact with the weld scar on the pipe 102, the force will push the grinding head 203 away from the pipe 102. At this time, the second motor 504 continues to drive the first mounting plate 201 to move closer to the pipe 102. The first rotation on the detection tube 601... When the moving ball 602 abuts against the side wall of the pipe 102, the rotation of the second motor 504 will stop under the detection of the image sensor 604. At this time, the grinding head 203 will slowly move closer to the pipe 102 under the gravity of the counterweight 302, and grind the weld scars on the pipe 102 under the rotation grinding action of the grinding blade 204. This achieves control over the grinding pressure of the grinding head 203, so that the grinding feed rate matches the material of the pipe 102, thereby improving the quality of grinding the weld scars on the pipe 102 and avoiding damage to the grinding blade 204 due to excessive feed speed of the grinding head 203. Furthermore, when the grinding blade 204 on the grinding head 203 comes into contact with the weld scar on the pipe 102, as the grinding head 203 moves away from the pipe 102, it will synchronously drive the rotating disk 707 on the return plate 705 to move upward. As the first motor 208 rotates, it will synchronously drive the second bevel gear 704 on the rotating rod 206 to rotate. Under the action of the meshing transmission between the second bevel gear 704 and the first bevel gear 703, it will drive the first rotating shaft 702 to rotate. As the first rotating shaft 702 rotates, it will synchronously drive the rotating disk 707 to rotate through the universal joint transmission rod 708. After the grinding head 203 finishes grinding the weld scars in the area, the rotating disk 707 will abut against the side wall of the pipe 102. Under the rotation of the rotating disk 707, the pipe 102 will be flipped, which not only avoids excessive grinding of the weld scars on the pipe 102 by the grinding head 203, but also realizes the automatic flipping of the pipe 102, thereby improving the quality and efficiency of grinding the weld scars on the pipe 102.
