Description

Technical Field

[0001] The invention relates to the technical field of valve flange processing, and in particular to an automatic valve grinding machine. Background Art

[0002] The valve mainly plays a shut-off role in the pipeline system, that is, it cuts off or closes the flow of fluid. This function ensures that the fluid does not flow without authorization, thereby ensuring the safety and stability of the system. Especially in various pipelines, the main responsibility of the valve is to achieve this shut-off effect. In addition, special types of valves such as check valves or one-way valves also have the function of preventing the backflow of the medium, which is also a manifestation of the shut-off effect. The main components of the valve are the valve body, valve cover, valve core, valve seat, valve stem, handle, transmission device and connecting flange.

[0003] Among them, the valve flange is generally processed and formed by casting. After casting, some burrs often remain on its surface. These burrs need to be polished before they can be welded to the valve body. The valve flange polishing device generally adopts coarse grinding and fine grinding methods for the valve flange. Some larger burrs can be quickly removed during coarse grinding, and the fine grinding is mainly to polish it. In the prior art, it is relatively simple to polish the end face of the valve flange. It can be polished by directly fixing it on the polishing workbench. However, when polishing the side surface, since the side surface has a certain curvature, it is necessary to control the rotation of the valve flange or the rotation of the grinder to ensure that the side surface can be polished clean. However, during coarse grinding and fine grinding, the speed of the valve flange is controlled or the speed of the grinder around the flange is controlled to be the same. In this case, a larger protrusion will hit the coarse grinding wheel during coarse grinding, causing damage to the grinding wheel. During fine grinding, the burrs will not be completely removed or the grinding efficiency will be low.

[0004] Therefore, we make improvements to this and propose an automatic valve grinding machine. Summary of the invention

[0005] (I) The technical problem to be solved by the present invention is: when the valve flange is roughly ground, the flange rotation speed is controlled to be slow to ensure that the grinding wheel is less damaged during the rough grinding; when the valve flange is finely ground, the flange rotation speed is controlled to be fast to ensure that the burrs are removed more thoroughly while ensuring the efficiency.

[0039] Specifically, at this time, the driving rod 41 drives the reciprocating screw rod 42 to rotate through the large toothed disc 420, the driving gear 2 419 and the driving shaft 22, and drives the adjusting block 44 to rise through the driving block 43, squeezing the speed regulating rotating rod 47 on the rear side to move forward, so that the bevel gear 2 418 on the front side of the rear driving bin 23 meshes with the bevel gear 1 417 on the front side, and cooperates with the spline sleeve 49 and the spline shaft 410 to drive the bevel gear 1 411 and the bevel gear 2 412 to rotate at a low speed, and then drives the electric push rod 34 to rotate at a low speed through the connecting shaft 413, and finally drives the valve flange at the lower end of the electric clamp 35 to rotate at a low speed, so that the left side grinder 28 performs rough grinding on it, and at the same time starts the water spraying device to spray coolant on the valve flange to cool the valve flange. At this time, the driving motor 21 continues to drive the intermittent toothed disc 23 to rotate through the driving shaft 22. After a period of time, when the driving wheel 26 moves to the lower end inside the S-shaped slide groove 25, it will pull the right grinder 28 to move to the left, and at this time, the adjusting block 44 continues to rise, squeezing the bevel gear 1 417 and the bevel gear 2 418 at the front end of the rear driving bin 2 33 to disengage, and make the rear bevel gear 1 417 mesh with the bevel gear 2 418, thereby driving the valve flange to rotate at high speed, so that the right grinder 28 can fine-grind the valve flange through the cooperation of the edge grinding mechanism 2, the feeding mechanism 3, and the rotating mechanism 4, so that when the valve flange is fine-grinded on the side, the larger protrusion on the valve flange can be avoided from hitting the rough grinding wheel and causing damage to the valve flange, and the larger protrusion can be fully and completely ground off, and the rotation speed of the valve flange can be increased during fine grinding, so that while ensuring the grinding efficiency, the smaller burrs on the valve flange can be ground more thoroughly.

[0040] In this embodiment, the feeding mechanism 3 includes a driving gear 1 31, a driving bin 1 32, a driving bin 2 33, an electric push rod 34 and an electric clamp 35.

[0041] In this embodiment, the lower ends of the driving gear 31 and the driving bin 32 are rotatably connected to the front and rear sides of the middle of the upper end of the workbench 1, and the side of the driving gear 31 close to the driving end of the driving motor 21 is meshed with the intermittent gear disc 23.

[0042] Specifically, the electric clamp 35 on the rear side is started to clamp the valve flange. At this time, the electric clamp 35 on the front side rotates to the upper end of the front conveyor belt 5, and the electric push rod 34 and the electric clamp 35 on the front side are started to clamp the valve flange on the upper end of the front conveyor belt 5. In the process of increasing the speed of the valve flange on the rear side, the valve flange on the front end is also gradually increasing its speed to remove some stains and residues remaining on the valve flange to avoid affecting the grinding. When the fine grinding is completed, the intermittent gear disc 23 drives the grinder 28 on the right side away from the valve flange, and the adjusting block 44 descends, gradually driving the valve flange to reduce its speed, and the front side The valve flange has an intermittent gear disc 23 and a feeding mechanism 3, and is transported backward to the middle of the upper end of the workbench 1. The valve flange that has been polished on the rear side moves backward and keeps rotating at a high speed for a period of time before rotating at a low speed, which is conducive to throwing away the coolant used during polishing on its surface. Through the cooperation of the edge grinding mechanism 2 and the feeding mechanism 3, the larger stains remaining on the valve flange can be thrown away during the automatic loading process to avoid affecting the polishing effect. In the process of automatic unloading, the residual coolant can be thrown away to reduce the amount of coolant remaining on its surface and save the amount of clean water used for later rinsing.

[0043] Working principle: First, install a coarse grinding wheel on the lower end of the left grinder 28, install a fine grinding wheel on the lower end of the right grinder 28, and place the upper nozzle of the water spray device filled with coolant on one side of the middle of the upper end of the workbench 1, and place the valve flanges that need to be edged on the left side of the upper end of the front and rear conveyor belts 5 in turn, start the electric baffle 6 on the left side of the upper end of the rear conveyor belt 5, conduct the rightmost valve flange to the left side of the right electric baffle 6, and place a valve flange on the lower end of the rear electric clamp 35, start the rear electric clamp 35, clamp the valve flange, start the drive motor 21, drive the intermittent gear disc 23 to rotate through the drive shaft 22, and then drive the front and rear drive gears 419 to rotate, and rotate the rear valve flange to the upper side of the workbench 1. At this time, the electric clamp 35 on the front side rotates to the upper end of the front conveyor belt 5, and the electric push rod 34 and the electric clamp 35 on the front side are started to clamp the valve flange on the upper end of the front conveyor belt 5. In the process of the electric clamp 35 on the rear side driving the valve flange to be transmitted to the middle of the upper end of the workbench 1, the driving wheel 26 cooperates with the S-shaped slide groove 25 in the middle of the adjusting disk 24 to drive the grinder 28 on the upper end of the left bracket 27 to move to the left, and move to the left to move toward the valve flange. When the valve flange is transmitted to the middle of the upper end of the workbench 1, the grinder 28 on the left side is transmitted to the right side to cooperate with the valve flange to roughly grind the valve flange. At this time, the driving rod 41 drives the reciprocating screw rod 42 to rotate through the large toothed disc 420, the driving gear 2 419 and the driving shaft 22. The drive block 43 drives the regulating block 44 to rise, and squeezes the speed regulating rod 47 on the rear side to move forward, so that the bevel gear 2 418 on the front side of the rear driving bin 2 33 is meshed with the bevel gear 1 417 on the front side, and cooperates with the spline sleeve 49 and the spline shaft 410 to drive the bevel gear disc 1 411 and the bevel gear disc 2 412 to rotate at a low speed, and then drives the electric push rod 34 to rotate at a low speed through the connecting shaft 413, and finally drives the valve flange at the lower end of the electric clamp 35 to rotate at a low speed, so that the left grinder 28 performs rough grinding on it, and at the same time starts the water spraying device to spray coolant on the valve flange to cool the valve flange. At this time, the driving motor 21 continues to drive the intermittent gear disc 23 to rotate through the driving shaft 22. After a period of time, when the driving wheel 26 is in the S-shaped After the internal movement of the slide groove 25 reaches the lower end, it will pull the right grinder 28 to move to the left, and at this time, the adjusting block 44 continues to rise, squeezing the bevel gear 1 417 and the bevel gear 2 418 at the front end of the rear driving chamber 2 33 to disengage, and make the bevel gear 1 417 on the rear side mesh with the bevel gear 2 418, thereby driving the valve flange to rotate at a high speed, so that the right grinder 28 can fine-grind the valve flange through the cooperation of the edge grinding mechanism 2, the feeding mechanism 3, and the rotating mechanism 4, so that when the valve flange is fine-grinded on the side, the larger protrusion on the valve flange can be prevented from hitting the rough grinding wheel and causing damage to the valve flange, and the larger protrusion can be fully ground off, and the rotation speed of the valve flange can be increased during fine grinding, so that while ensuring the grinding efficiency,The grinding of smaller burrs on the valve flange is more thorough. In the process of increasing the speed of the rear valve flange, the front valve flange is also gradually increasing its speed, and some stains and residues remaining on the valve flange are removed to avoid affecting the grinding. After the fine grinding is completed, the intermittent gear disc 23 drives the grinder 28 on the right side away from the valve flange, and the adjustment block 44 descends, gradually driving the valve flange to reduce the speed. In addition, the front valve flange is transported backward to the middle of the upper end of the workbench 1 by the cooperation of the intermittent gear disc 23 and the feeding mechanism 3. The valve flange on the rear side that has been polished moves backward and keeps high-speed rotation for a period of time before rotating at a low speed, which is conducive to throwing away the coolant used on its surface during grinding. Through the cooperation of the edge grinding mechanism 2 and the feeding mechanism 3, the larger stains remaining on the valve flange are thrown away during the automatic feeding process to avoid affecting the grinding effect. In the process of automatic unloading, the residual coolant is thrown away, reducing the amount of coolant remaining on its surface, saving the amount of clean water used for later flushing.
