Description

Technical Field

[0001] The invention belongs to the technical field of grinding equipment, and in particular relates to an outer circle grinding device for a magnetic level gauge flange. Background Art

[0002] The flange of the magnetic level gauge is a component used to connect the magnetic level gauge and the container. Its function is to provide a stable connection interface to ensure that the level gauge can accurately measure the liquid level in the container.

[0003] The flange of the magnetic level gauge needs to be ground on its outer circle during the production process to ensure that the connection between the flange and other components is tighter and more accurate, making the outer circle surface of the flange smoother, reducing roughness, improving sealing performance, and further making the appearance of the flange neater and more beautiful. At present, most of the flanges are clamped and fixed by clamps, and then sandpaper is placed on the outer edge of the flange, and the flange is rotated to achieve the grinding of the outer circle of the flange. In actual processing, the grinding speed is fixed, and the technicians roughly adjust it according to the specific style and size of the flange. This grinding speed adjustment method is not accurate enough. For thinner flanges, due to the relatively small amount of material removal, the grinding speed needs to be appropriately increased during grinding to ensure processing efficiency. For thicker flanges, heat accumulation during grinding is high. There are more aggregates. In order to avoid thermal damage and improve the processing quality, the grinding speed needs to be appropriately reduced. In addition, the overall grinding time requires professional technicians to constantly observe the grinding status of the flange for adjustment, which is very inconvenient and requires frequent shutdowns for observation, affecting the grinding efficiency. The sandpaper board will gradually wear out during the grinding work, so it needs to be replaced regularly, but the degree of wear of the sandpaper depends on the grinding workload. At present, the grinding workload cannot be accurately judged, resulting in the replacement of the sandpaper board mostly using the means of regular replacement. Too frequent replacement not only requires shutdown to affect the grinding efficiency, but also will cause waste of sandpaper board due to insufficient grinding workload. The relatively sparse grinding frequency will cause the sandpaper board to reach its use limit long ago, and then the low quality of the sandpaper board will cause damage to the flange, affecting the processing quality of the flange.

[0031] A flange thickness detection feedback adjustment mechanism 6 is fixedly installed on one side of the lower end of the bidirectional clamping fixing mechanism 2, and the flange thickness detection feedback adjustment mechanism 6 includes a feedback shell 61 fixedly inserted in the side wall of the lower end of the positioning plate 22, and a resistor rod 62 is fixedly installed on the upper side of the inner wall of the feedback shell 61.

The front end of the synchronization rod 63 is fixedly connected to the rear side of the lower end of the moving plate 24, and the upper side of one end of the synchronization rod 63 located in the feedback shell 61 is fixedly connected with a conductive contact 64 that is electrically in contact with the resistor rod 62. The conductive contact 64 and the resistor rod 62 are respectively connected in series to the power supply circuits of the DC motor drive assembly 210, the suction electromagnetic plate 312 and the thrust electromagnetic plate 57.

[0032] A PLC controller 7 is fixedly mounted on one side of the upper end of the base 1 .

[0033] The operating principle of the present invention is described as follows: first, the flange to be processed is placed between the two clamping plates 27, and the electric push rod 23 is started. The electric push rod 23 drives the moving plate 24 to move, so that the two clamping plates 27 are close to each other to clamp and fix the flange. The plug-in column 28 on the side wall of the clamping plate 27 is inserted into the bolt hole on the surface of the flange to achieve a stable limit to the flange. As the moving plate 24 moves, the lower end of the moving plate 24 drives one end of the synchronization rod 63 to move at the same time, so that the conductive contact piece 64 connected to the other end of the synchronization rod 63 moves on the resistor rod 62. When the thickness of the flange is The larger the diameter of the flange, the smaller the moving distance of the synchronization rod 63, and the smaller the sliding distance of the conductive contact 64 on the resistor rod 62, so that the access resistance of the resistor rod 62 is larger. On the contrary, when the thickness of the flange is smaller, the moving distance of the synchronization rod 63 is relatively larger, so that the sliding distance of the conductive contact 64 on the resistor rod 62 is larger, so that the access resistance of the resistor rod 62 is smaller, and the flange can be quickly clamped and fixed, which is convenient for subsequent grinding operations. While fixing the flange, the thickness of the flange can be fed back and detected, which serves as an adjustment basis for subsequent grinding operations, and is convenient to use.

[0034] When the flange is completely fixed by the clamping plates 27 on both sides, the clamping force generated between the two clamping plates 27 is fed back to the pressure sensor 29 so that the pressure value of the pressure sensor 29 reaches the preset value. At this time, the PLC controller 7 controls the electric push rod 23 to stop the pushing action, and controls the electric telescopic rod 32 to drive the L-shaped lifting plate 33 to move downward, so that the sandpaper board 38 in the L-shaped lifting plate 33 is in contact with the outer side of the end of the flange. Since the conductive contact 64 and the resistor rod 62 are connected in series to the power supply circuit of the suction electromagnetic plate 312, the thicker the flange is, the greater the connection resistance of the resistor rod 62 is, which makes the power supply current of the suction electromagnetic plate 312 smaller, and the magnetism of the suction electromagnetic plate 312 weaker, thereby making the suction electromagnetic plate 312 to the suction permanent magnet plate 311 more attractive. The gravitational force is weak, so that the distance that the force-bearing plate 39 moves to overcome the elastic force of the return spring 310 is small, and then the distance that the L-shaped push-pull plate 35 cooperates with the push-pull rod 36 to drive the side fixing plate 37 to move is small, so that the distance between the vertical part of the L-shaped lifting plate 33 and the side fixing plate 37 is relatively large, which meets the grinding of thicker flanges. On the contrary, when the flange is thinner, the access resistance value of the resistor rod 62 is smaller, and the magnetism of the suction electromagnetic plate 312 is stronger, so that the moving distance of the side fixing plate 37 is larger, and the distance between the vertical part of the L-shaped lifting plate 33 and the side fixing plate 37 becomes smaller, which meets the grinding of thinner flanges. The distance of the grinding part can be adjusted based on the thickness of the flange to ensure that the sandpaper board 38 and the flange are stably and accurately in contact, and the outer circle of the flange can be quickly and effectively ground.

[0035] During the grinding process, the PLC controller 7 controls the DC motor drive assembly 210 to drive the rotating shaft 25 to drive the clamping plate 27 on one side to rotate, thereby driving the flange to rotate at a high speed, and cooperating with the sandpaper board 38 to grind the outer circle of the flange. The conductive contact 64 and the resistor rod 62 are also connected in series to the power supply circuit of the DC motor drive assembly 210. When the flange is thicker, the access resistance of the resistor rod 62 is larger, thereby making the power supply current of the DC motor drive assembly 210 smaller, making the working power of the DC motor drive assembly 210 smaller, and making the speed of the DC motor drive assembly 210 lower. On the contrary, when the flange is thinner, the access resistance of the resistor rod 62 is smaller, making the speed of the DC motor drive assembly 210 higher. The grinding speed can be automatically adjusted based on the thickness of the flange, so as to meet the requirements of increasing the grinding speed and improving the processing efficiency of the thinner flange and reducing the grinding speed of the thicker flange to avoid thermal damage and improve the processing quality.

[0036] The rotating shaft 25 drives the flange to rotate and drives the cam 46 to rotate synchronously at the same time. The protruding part of the cam 46 continuously squeezes and pushes on the squeezing plate 44. The squeezing plate 44 cooperates with the squeezing rod 43 to overcome the elastic force of the compensation spring 45 to drive the booster piston 42 to move in the booster box 41, and the grinding hydraulic pressure in the booster box 41 is sent to the universal serpentine metal tube 47 and sprayed out through the spray head 48 to act on the flange. The position of the spray head 48 can be adjusted based on the arbitrarily deformable characteristics of the universal serpentine metal tube 47 and installed on the side of the flange. It is suitable for the use of flanges of different sizes. The wheel 46 is separated from the pushing plate 44, and the boosting piston 42 is moved back under the action of the compensation spring 45, forming a negative pressure suction in the boosting box 41, and the grinding fluid is replenished into the boosting box 41 again in cooperation with the liquid replenishing pipe 49, so that the grinding fluid can be sprayed synchronously when the flange is ground, which helps to reduce the grinding heat and the occurrence of chatter marks in the grinding of the flange, and the spraying amount of the grinding fluid can be synchronously adjusted based on the grinding speed, meeting the requirement that the faster the grinding speed, the more the grinding fluid spraying amount, thereby ensuring the grinding quality and avoiding the waste of grinding fluid;

[0037] When the rotating shaft 25 rotates, the linkage telescopic rod 514 drives the input end of the reduction gear box 513 to rotate, and the output end of the reduction gear box 513 drives the rotating screw 58 to rotate at a reduced speed. The threaded sleeve connection between the rotating screw 58 and the pressing plate 59 causes the pressing plate 59 to gradually move in the control housing 51. When the pressing convex head 510 at one end of the pressing plate 59 acts on the replacement feedback switch 511, it indicates that the grinding amount of the sandpaper board 38 has reached the standard and needs to be replaced. The faster the grinding speed, the faster the relative movement speed of the pressing plate 59, which acts on the replacement feedback switch 511. The smaller the interval time on the feedback switch 511, the higher the frequency of replacement of the sandpaper board 38 is required. Based on the grinding speed and the amount of grinding processing, the warning of the need to replace the sandpaper board 38 can be automatically and accurately fed back to avoid the problem that too frequent replacement not only requires downtime to affect the grinding efficiency, but also causes the sandpaper board 38 to be wasted due to insufficient grinding workload. A relatively sparse grinding frequency will cause the sandpaper board 38 to reach its usage limit early, and then the flange will be damaged due to the low quality of the sandpaper board 38, affecting the processing quality of the flange.

[0038] When the pressing plate 59 acts on the trigger stop switch 54 on the trigger plate 53, it indicates that the grinding work on the flange is completed, and the conductive contact 64 and the resistor rod 62 are connected in series on the power supply circuit of the thrust electromagnetic plate 57. When the thickness of the flange is larger, the access resistance of the resistor rod 62 is larger, and the power supply current of the thrust electromagnetic plate 57 is smaller, resulting in weaker magnetism of the thrust electromagnetic plate 57. The thrust electromagnetic plate 57 cooperates with the thrust permanent magnet plate 56 to drive the trigger plate 53 to overcome the elastic force of the pull-down spring 55 and move up. The distance is shorter, and the distance between the trigger stop switch 54 and the pressing plate 59 is larger, which can increase the grinding time of the flange, and can automatically calculate the grinding time of the entire flange based on the thickness of the flange, so as to meet the requirement that thicker flanges require more grinding times and time to complete the processing.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
