Description

Technical Field

[0001] This utility model belongs to the field of rotary plug processing and manufacturing technology, and in particular relates to a rotary plug inner cavity grinding device for rotary plug processing and manufacturing. Background Technology

[0002] A plug valve is a type of valve that consists of a rotatable, perforated conical plug inserted into the center hole of the valve body. When the plug's orifice faces the valve body's inlet or outlet, fluid can pass through the plug. When the plug is rotated 90° and its orifice is completely blocked by the valve body, fluid cannot pass through. Therefore, it can function as both an opening / closing valve and a regulating valve.

[0003] However, existing grinding devices, when grinding the inner cavity of a stopcock, cannot quickly grind according to the varying diameters of the stopcock cavities, as the devices lack adjustment capabilities. Furthermore, grinding generates waste chips, which, due to the lack of a rapid collection function, remain on the device, affecting the working environment. Therefore, we provide a stopcock inner cavity grinding device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary valve inner cavity grinding device for rotary valve processing and manufacturing. By controlling the distance between the grinding block and the processing column, it is possible to perform rapid grinding work according to different heights and sizes of the rotary valve inner cavity. At the same time, the installation of the screen frame facilitates the recycling of the generated waste.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rotary valve internal cavity grinding device, comprising a top plate and a bottom plate located directly below the top plate; a processing plate is provided between the top plate and the bottom plate, and an installation port is provided at the middle of the upper part of the processing plate. A screen frame is provided at the installation port and bolted to the processing plate. A processing column is provided directly above the screen frame. Three grinding blocks are evenly distributed around the surface of the processing column. Limiting holes are provided on the surface wall of the processing column corresponding to the positions of the grinding blocks. A movable hole is provided at the inner end of the limiting hole. A movable rod passing through the limiting hole is fixed to the side wall of the grinding block near the processing column.

[0007] The present invention is further configured such that positioning rods are fixed at the four corner positions between the top plate and the bottom plate, and the processing plate is fitted onto the positioning rods through the through holes opened at the corners.

[0008] The present invention is further configured such that a lifting telescopic rod with a telescopic end bolted to the bottom surface of the processing plate is fixed on the upper end of the base plate on both sides of the mounting port, and a clamping cylinder is fixed on the upper end of the processing plate on both sides of the mounting port.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1 to 7 This utility model is a rotary valve inner cavity grinding device for rotary valve processing and manufacturing. By controlling the distance between the grinding block 4 and the processing column 3, it can achieve rapid grinding work according to different heights and sizes of the rotary valve inner cavity. At the same time, the installation of the screen frame 201 facilitates the recycling of the generated waste.

[0031] Specifically, there is a top plate 1 and a bottom plate 103 located directly below the top plate 1; a processing plate 2 is provided between the top plate 1 and the bottom plate 103, and an installation opening 203 is provided at the middle of the upper end of the processing plate 2. A screen frame 201 is provided at the installation opening 203 and bolted to the processing plate 2. A processing column 3 is provided directly above the screen frame 201. There are three grinding blocks 4 evenly distributed around the circumference on the surface of the processing column 3. Limiting holes 309 are provided on the surface wall of the processing column 3 corresponding to the positions of the grinding blocks 4 for limiting. An movable hole 308 is provided at the inner end of the hole 309. A movable rod 402 passing through the limiting hole 309 is fixed on the side wall of the grinding block 4 near the processing column 3. Positioning rods 102 are fixed at the four corner positions between the top plate 1 and the bottom plate 103. The processing plate 2 is sleeved on the positioning rods 102 through the through holes opened at the corners. A lifting telescopic rod 101 with a telescopic end bolted to the bottom surface of the processing plate 2 is fixed on the upper end of the bottom plate 103 on both sides of the mounting port 203. A clamping cylinder 202 is fixed on the upper surface of the processing plate 2 on both sides of the mounting port 203.

[0032] The operation process of this embodiment is as follows: Using the above-described structure, the stopcock is placed on the upper surface of the screen frame 201, and the clamping cylinder 202 is controlled to clamp the stopcock, aligning the stopcock's port with the processing column 3. Then, the lifting telescopic rod 101 is used to control the processing plate 2 to move upwards, allowing the processing column 3 to enter the stopcock. By controlling the rotation of the processing column 3, the grinding block 4 is driven to rotate rapidly along the inner cavity of the stopcock, thereby grinding the inner wall of the stopcock. The resulting debris will fall from the bottom of the stopcock. The waste falls onto the screen frame 201 at the port position, so the corresponding recycling bin is placed directly below the screen frame 201. The waste then falls from the screen frame 201 into the recycling bin, achieving rapid recycling of the waste. At the same time, after the processing column 3 and the grinding block 4 are inside the stopcock, the distance between the grinding block 4 and the processing column 3 is adjusted so that the grinding block 4 can always be in contact with the inner cavity of the stopcock, thereby enabling the entire inner cavity of the stopcock to be ground. This allows for rapid grinding work based on the different heights and sizes of the inner cavity of the stopcock.

[0033] Example 2

[0034] Please see Figure 3 , Figure 4, Figure 5 , Figure 6 and Figure 7 Based on Example 1, the linkage plate 303 and the synchronization plate 407 work in stages to drive multiple grinding blocks 4 to move at equal distances, thereby achieving synchronous work between structures and ensuring stable grinding.

[0035] Specifically, a movable cylinder 305 is fixed to the upper end face of the processing column 3, and an assembly plate 304 is fixed to the upper end face of the movable cylinder 305. A motor 301 connected to the assembly plate 304 is fixed to the end face of the top plate 1. Adjusting cylinders 302 are fixed to the upper end faces of the top plate 1 on both sides of the motor 301. Multiple curved holes 307 are opened inside the processing column 3, which are respectively connected to the inside of the movable hole 308. A synchronous plate 407 is set inside the movable cylinder 305. Multiple pushing rods 406 inserted into the curved holes 307 are fixed to the lower end face of the synchronous plate 407. A compression plate 403 is fixed to the end face of the movable rod 402 inside the movable hole 308. Each of the lower end faces is fixed with a rubber flexible rod 405 that abuts against the corresponding compression plate 403. The end face of the compression plate 403 is fixed with a spring 404 sleeved on the movable rod 402, and the other end of the spring 404 abuts against the inner wall of the movable hole 308. The outer wall of the movable cylinder 305 is fitted with a moving ring 401 that is the same height as the synchronous plate 407. The outer wall of the movable cylinder 305 is provided with an adjustment port 306 that communicates with its interior. The inner wall of the moving ring 401 is fixedly connected to the outer wall of the synchronous plate 407 through a fixed protrusion. The bottom of the top plate 1 is provided with a linkage plate 303 that rotates with the moving ring 401, and the linkage plate 303 is bolted to the piston end of the adjusting cylinder 302.

[0036] The operation process of this embodiment is as follows: When the processing column 3 and the grinding block 4 are inside the stopcock, the control adjustment cylinder 302 is activated. The adjustment cylinder 302 drives the moving plate to move up and down along the movable cylinder 305 through the linkage plate 303. Thus, the moving ring 401 directly controls the synchronous plate 407 to slide up and down in the movable cylinder 305. When the synchronous plate 407 moves downward, it pushes multiple push rods 406 to control the rubber flexible rod 405 to bend and move. Through the compression plate 403 and the movable rod 402, it pushes the grinding block 4 to move away from the processing column 3, thereby increasing the distance between the grinding block 4 and the processing column 3. When the synchronous plate 407 moves upward, the rubber flexible rod 405 is pulled upward and will not squeeze the compression plate 403. At this time, the spring 404 pushes the compression plate 403 to reset and drives the grinding block 4 to reset through the movable rod 402, thereby reducing the distance between the grinding block 4 and the processing column 3.

[0037] It should be noted that the rotation between the linkage plate 303 and the moving ring 401 is achieved by the engagement of the annular groove on the inner side of the linkage plate 303 and the protrusion on the outer side of the moving ring 401.
