Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a multifunctional cleaning, grinding and polishing device for mechanical parts. Background Art

[0002] After the production of mechanical parts is completed, burrs and other impurities remaining on the surface need to be removed by polishing and cleaning. At the same time, the impurities remaining on the surface of mechanical parts after use can also be removed in the same way. Steel pipes are a common type of mechanical parts. When polishing and cleaning steel pipes, magnetic polishing machines are used as a type of steel pipe polishing. By adding clean water and cleaning agents to the polishing container, the magnetic field is used to drive the magnetic abrasive to rotate, and then the steel pipe is polished. When polishing the steel pipe, the rotation of the abrasive will cause the wastewater generated by polishing to splash, and the wastewater is easy to contaminate other areas of the equipment. Workers are required to clean the contaminated areas later, increasing labor costs. At the same time, the rotation of the abrasive will cause adjacent steel pipes to move, which can easily cause collisions and damage between the steel pipes, causing damage to the steel pipes. At the same time, the impurities generated by the polishing of the steel pipe float in the wastewater, and the steel pipe needs to be manually removed from the polishing machine for cleaning, increasing labor costs.

[0003] At the same time, due to the hollow structure of the steel pipe, abrasives are easy to remain on the inner surface of the steel pipe when polishing it.

[0020] The cleaning assembly includes a bellows 102, a fixed plate 104, a limit rod 105 and a rotating plate 106; a bellows 102 is fixedly connected to the inner left and inner right parts of the polishing barrel 2, and the bellows 102 is made of elastic rubber material; two fixed plates 104 are fixedly connected to the inner side of the polishing barrel 2; a number of limit rods 105 are commonly fixedly connected between the two fixed plates 104; except for the limit rods 105 located at the front and rear sides of the fixed plate 104, which are rotatably connected to a rotating plate 106, the remaining limit rods 105 are rotatably connected to two rotating plates 106, and two adjacent rotating plates 106 are in contact with each other.

[0021] The water inlet and outlet assembly includes a water inlet pipe 3 and a drain pipe 4; the water inlet pipe 3 is connected to the left and right sides of the polishing barrel 2; the drain pipe 4 is connected to the left side of the polishing barrel 2, and the drain pipe 4 is located below the left water inlet pipe 3; each water inlet pipe 3 and drain pipe 4 is connected to an external water pumping device.

[0022] It also includes a slide plate 103 and an electromagnetic valve 107 ; each corrugated cover 102 is fixedly connected to a slide plate 103 on one side facing the middle of the polishing barrel 2 ; each slide plate 103 is connected to an electromagnetic valve 107 .

[0023] It also includes a valve 108 ; a plurality of valves 108 are fixedly connected to the slide plate 103 on the left side; each valve 108 is located below the electromagnetic valve 107 .

[0024] A filter screen 201 is also included; a filter screen 201 is fixedly connected to the lower side of each two adjacent rotating plates 106 .

[0025] A warping portion 10301 is provided on the slide plate 103 located on the left side.

[0026] Each rotating plate 106 is made of rubber material, and each rotating plate 106 is rotationally connected to the limiting rod 105 via a torsion spring.

[0027] The surfaces of the first separation plate 6 and the second separation plate 7 are both covered with a rubber layer to prevent the first separation plate 6 and the second separation plate 7 from scratching the surface of the steel pipe, thereby ensuring the quality of the steel pipe after polishing and cleaning.

[0028] The following descriptions are based on Figure 1 is the viewing angle reference, Figure 1 In the figure, the side where the magnetic polishing machine 1 is located is the front side, and the side where the water inlet pipe 3 is located is the left side.

[0029] After the worker puts the steel pipe that needs to be polished and cleaned into the polishing barrel 2, he injects clean water and cleaning agent into the water inlet pipe 3 through the external water pumping equipment and the chemical delivery equipment. After the liquid covers the steel pipe and is lower than the height of the polishing barrel 2, the worker pours the polishing abrasive into the polishing barrel 2, starts the magnetic polishing machine 1 to make the abrasive rotate at high speed under the action of the magnetic field, and then grinds and polishes the surface of the steel pipe. When the polishing of the steel pipe is completed, the drain pipe 4 is sucked through the external water pumping equipment to discharge the cleaned impurities and sewage from the polishing barrel 2.

[0030] In the process of grinding and polishing the steel pipe, considering that the rotation of the abrasive will drive the polishing liquid to splash out of the polishing barrel 2, causing the liquid containing impurities to splash and pollute other areas of the equipment, before polishing and cleaning, the electric slide rail 101 is started to drive the cover plate 5 to move downward, and the upper side of the polishing barrel 2 is covered by the cover plate 5, so that the sewage in the polishing process cannot splash from the top of the polishing barrel 2 to other areas of the equipment. It should be noted that: Figure 6 As shown, the dotted line represents the highest water level. The lower end of the electric slide rail 101 is always not in contact with the liquid inside the polishing barrel 2. At the same time, the polishing barrel 2 is replaced by the rotating plate 106 to carry the steel pipe and clean water. Figure 4As shown, the worker adapts the first separation plate 6 and the second separation plate 7 to the diameter of the steel pipe and then inserts them into the mounting grooves on the cover plate 5 respectively. When the cover plate 5 moves downward, the cover plate 5 also drives the first separation plate 6 and the second separation plate 7 to move downward synchronously. When the lower sides of the first separation plate 6 and the second separation plate 7 contact the rotating plate 106, the cover plate 5 stops moving. At this time, the cover plate 5 seals the top of the polishing barrel 2. Considering that the rotation of the abrasive will cause the steel pipe in the liquid to move, this phenomenon may easily lead to collision and damage between two adjacent steel pipes. The single steel pipe is isolated by the first separation plate 6 and the second separation plate 7 after contacting the rotating plate 106, so that the steel pipe is confined between the first separation plate 6 and the second separation plate 7, so that the steel pipe cannot move back and forth in the polishing barrel 2, thereby preventing the two adjacent steel pipes from colliding with each other and being damaged during the polishing and cleaning process.

[0031] It is also considered that after the steel pipe is polished and cleaned, the cover plate 5 continues to move downward, thereby driving the first separation plate 6 and the second separation plate 7 to continue to move downward, so that all the rotating plates 106 are subjected to downward extrusion force as shown in FIG. Figure 5 It should be noted that the rotating plate 106 is initially held in the same state by the force of the torsion spring. Figure 2 As shown, the rubber material of the rotating plate 106 is used to fit each other and seal to prevent liquid leakage. It should be noted that the gap between two adjacent rotating plates 106 after rotation is smaller than the diameter of the steel pipe. At this time, the steel pipe cannot fall over the two adjacent rotating plates 106, so that the abrasive and sewage pass through the rotating plate 106 and are discharged into the filter 201. At the same time, after the clean water is poured into the water inlet pipe 3, the clean water is poured into the polishing barrel 2 through the corrugated cover 102 to rinse the polished steel pipe. At the same time, the clean water that flushes the steel pipe also passes through the rotating plate 106 to the filter. The abrasive on 201 is rinsed, so that the impurities remaining on the surface of the steel pipe and the abrasive are washed away together. There is no need for subsequent workers to take out the steel pipe and the abrasive for cleaning separately, thereby reducing labor costs. When the next batch of steel pipes needs to be polished, the workers only need to remove the abrasive collected on the filter screen 201, control the cover plate 5 to move upward back to the initial position, and then drive the first separation plate 6 and the second separation plate 7 to move upward, pour the abrasive back on the rotating plate 106, and then add new polishing liquid to carry out load-bearing polishing work on the next batch of steel pipes.

[0032] It is also taken into consideration that when the steel pipe is limited by the first separation plate 6 and the second separation plate 7, the first separation plate 6 and the second separation plate 7 will hinder the abrasive, making it difficult for the abrasive to polish the part of the steel pipe that contacts the first separation plate 6 and the second separation plate 7, resulting in uneven polishing of the steel pipe. In order to avoid this phenomenon, when the cover plate 5 is lowered and the polishing work is carried out for a period of time, clean water is pumped into the water inlet pipe 3 on the left side through an external water pumping device, so that after the clean water is poured into the corrugated cover 102, the clean water cannot be discharged into the polishing barrel 2 due to the restriction of the slide plate 103, and then the corrugated cover 102 made of elastic rubber material stretches to the right under the restriction of the polishing barrel 2 and the cover plate 5, and the slide plate 103 is pushed toward the position of the steel pipe by the effect of water pressure. When the slide plate 103 contacts the steel pipe, the slide plate 103 pushes the steel pipe to move to the right, thereby changing the contact position of the steel pipe with the first separation plate 6 and the second separation plate 7. It should be noted that: at this time, the liquid level in the polishing barrel 2 is always lower than the lower side of the electric slide rail 101. At this time, the abrasive continues to polish the steel pipe, which solves the problem of uneven polishing caused by limiting the steel pipes to prevent them from colliding with each other, and improves the polishing effect of the equipment on the steel pipe. When the steel pipe needs to be flushed, it is only necessary to start the electromagnetic valve 107 to open it, so that clean water is discharged to the polishing barrel 2 through the slide plate 103 to clean the steel pipe. At this time, the slide plate 103 loses the force of water pressure and is gradually contracted by the corrugated cover 102 made of elastic rubber material and brought back to the initial position.

[0033] It is also taken into consideration that, when the steel pipe is being polished, abrasives easily enter the inner annular surface of the steel pipe, and some abrasives will remain inside the steel pipe after polishing is completed. It is difficult to flush out the abrasives remaining on the inner annular surface of the steel pipe by passing clean water into the polishing barrel 2, resulting in that when the steel pipe is subsequently taken out, the abrasives easily fall to the ground during the transportation of the steel pipe and are difficult to collect, causing cost losses. In order to avoid this phenomenon, clean water is poured into the two water inlet pipes 3 at the same time, so that the two corrugated covers 102 push the two slide plates 103 to move left and right respectively, and then press against the left and right ends of the steel pipe. At this time, the water inlet pipe 3 on the left continues to be filled with clean water, thereby pushing the slide plate 103 on the left to continue to move toward the steel pipe. Since the steel pipe is restricted by the first separation plate 6 and the second separation plate 7, and blocked by the slide plate 103 on the right, the steel pipe pushes open the valve 108 on the left slide plate 103. Then, the clean water in the bellows 102 and the slide plate 103 is directly rushed into the steel pipe through the valve 108. At this time, the electromagnetic valve 107 on the right slide plate 103 is controlled to open, and the clean water is discharged to the polishing barrel 2 to rinse the surface of the steel pipe. At the same time, the right slide plate 103 is brought back to the initial position under the contraction of the right bellows 102, so that the right side of the steel pipe is connected with the polishing barrel 2, and then the clean water rushed into the steel pipe is discharged from the right side of the steel pipe, and finally discharged to the polishing barrel 2. In this way, the abrasive remaining on the inner ring surface of the steel pipe is flushed out to avoid the abrasive remaining in the steel pipe and affecting the subsequent use of the steel pipe, while avoiding cost losses. Furthermore, when the warping portion 10301 arranged on the left slide plate 103 is pushed against the steel pipe, it cooperates with the first separation plate 6 and the second separation plate 7 to lift the left end of the steel pipe upward and guide it to the valve 108.

[0034] Example 2 On the basis of Example 1, Figure 2 and Figure 8 As shown, it also includes a pressure plate 202; a plurality of electric slide rails 101 are slidably connected to a pressure plate 202; the pressure plate 202 also has a plurality of mounting grooves; the second separation plate 7 is detachably connected to the mounting groove on the pressure plate 202, and the second separation plate 7 is slidably connected to the mounting groove on the cover plate 5.

[0035] A rubber ball is provided on one side of each first separation plate 6 facing the second separation plate 7 to increase the friction between the first separation plate 6 and the steel pipe, push the steel pipe to rotate on the opened rotating plate 106, and improve the equipment's cleaning ability for the steel pipe.

[0036] When cleaning the steel pipe, the clean water after flushing the steel pipe and then flushing the abrasive will easily bring the impurities washed away from the surface of the steel pipe to the abrasive, and the abrasives are small in size and easy to accumulate with each other, resulting in impurities being mixed between the abrasives. It is difficult to flush the impurities mixed between the abrasives only by flushing, resulting in the abrasives being mixed with impurities to polish the steel pipes when the next batch of steel pipes are polished and cleaned, and the polishing and cleaning effect of the steel pipes is deteriorated. In order to avoid this phenomenon, when the abrasive falls on the filter screen 201, the electric slide rail 101 is started to first drive the cover plate 5 to move downward, and then when the cover plate 5 is reset upward, the abrasive is brought to the filter screen 201. The movable pressure plate 202 moves downward, and reciprocates in this way, so that the first separation plate 6 first moves downward to push open the rotating plate 106 located on the lower side of the first separation plate 6, and then the second separation plate 7 pushes open the rotating plate 106 located on the lower side of the second separation plate 7, so that the two adjacent rotating plates 106 are staggered to open, and then the two ends of the filter screen 201 move up and down respectively. In this way, the abrasives covered on the filter screen 201 are rolled and rubbed against each other, and the impurities mixed in the abrasives are discharged and flushed out by the rubbing of the abrasives themselves and the clean water discharged from the water inlet pipe 3, so as to avoid residual impurities between the abrasives and improve the equipment's polishing and cleaning ability for steel pipes.

[0037] It should be noted that in Example 1, when the cover plate 5 moves downward to drive the first separation plate 6 and the second separation plate 7 to restrict the steel pipe and squeeze the turn plate 106, the electric slide rail 101 synchronously drives the cover plate 5 and the pressure plate 202 to move downward.
