Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically to a valve body end face processing device. Background Technology

[0002] The valve body is an important component of a valve. Its main processing methods are casting and forging. However, regardless of the method used to manufacture the valve body, its end face must be ground and polished after the valve body is formed to ensure the sealing performance of the valve body during use. The polishing machine is an important piece of equipment for polishing the end face of the valve body.

[0003] However, in practical use, for valve bodies of different sizes, the clamping needs to be adjusted according to their different shapes during processing. Traditional extrusion devices clamp the valve body by using extrusion blocks with fixed shapes on both sides, which can easily lead to insufficient tightness between the extrusion blocks and the valve body. At the same time, for irregularly shaped valve bodies, traditional extrusion blocks cannot fit well with the valve body. Therefore, a clamping device that can be easily adjusted is needed to achieve the effect of clamping and processing valve bodies of different sizes through adjustment in multiple directions and clamping positions, avoiding the need to replace clamping blocks and improving the efficiency of clamping and processing different workpieces. Utility Model Content

[0004] The purpose of this invention is to provide a valve body end face processing device, which solves the problem that existing valve body processing requires a convenient adjustment and clamping device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a valve body end face processing device, including a base plate, a movable plate and a lifting frame. The movable plate is provided at the top center of the base plate, and lifting frames are provided on both sides of the top of the base plate. A first electric push rod is fixedly connected to the center of the inside of the lifting frame. A second electric push rod is provided through the inside of the lifting frame on both sides near the first electric push rod. A connecting block is installed at one end of the first electric push rod and the second electric push rod near the center of the base plate.

[0006] The top of both sides of the base plate is fixedly connected to a side plate, the bottom of the movable plate is slidably connected to the top of the side plate, and an electric telescopic rod is fixedly connected to the center of the movable plate.

[0007] The second electric push rod has sliders installed on the outer wall near the inside of the lifting frame. The inside of the lifting frame has rectangular holes that slide corresponding to the sliders. Adjusting screws are installed through the top and bottom of the slider at the end away from the connecting block.

[0008] A central rod is fixedly connected through the center of the connecting block. Rubber rings are sleeved around the top and bottom of the central rod, and a compression bolt is threaded onto one side of the rubber ring.

[0009] Preferably, both ends of the movable plate are threaded with fixing bolts near the top of the side plate, and the fixing bolts penetrate the interior of the movable plate and are pressed against each other by the side plate.

[0010] Preferably, the top and bottom of the connecting block are both sleeved with rubber rings, and the inner protruding ends of the first electric push rod and the second electric push rod are fixedly connected to one end of the connecting block.

[0011] Preferably, the slider is T-shaped, one side of the slider is slidably connected to the inside of the rectangular hole, the two ends of the adjusting screw have opposite threads, and the ends of the second electric push rod and the first electric push rod away from the connecting block are in contact with the side wall of the side plate.

[0012] Preferably, both ends of the lifting frame are internally threaded with rotating screws, and the bottom of each rotating screw is rotatably connected to the top of the base plate via a rotating shaft.

[0013] Preferably, a cleaning module is fixedly connected to the bottom protruding end of the electric telescopic rod, and a grinding device is installed inside the cleaning module. The top of the base plate is inclined to the bottom at both sides away from the side plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] Rotating the adjusting screw causes the sliders at both ends to slide along the inside of the rectangular hole, which in turn moves the second electric push rod. This causes the connecting block at the extended end of the second electric push rod to approach the valve body, activating the second electric push rod. This causes the connecting block at one end of the second electric push rod to move closer to the valve body, which in turn causes the central rod to move the rubber ring closer to the valve body, thus squeezing and fixing the center of the valve body on both sides. Simultaneously, when fixing valve bodies of different heights, rotating the adjusting screw causes the lifting frame to move up and down. The lifting frame, through the slider, moves the first and second electric push rods, causing the connecting block to move accordingly, thus adjusting the height of the rubber ring. Furthermore, rotating the compression bolt releases the rubber ring, further adjusting its position, facilitating the clamping and fixing of valve bodies of different sizes.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The valve body end face processing device shown includes a base plate 1, a movable plate 2, and a lifting frame 3. The movable plate 2 is located at the top center of the base plate 1, and lifting frames 3 are located on both sides of the top of the base plate 1. A first electric push rod 4 is fixedly connected to the center of the interior of the lifting frame 3. A second electric push rod 401 is installed through the interior of the lifting frame 3 on both sides near the first electric push rod 4. A connecting block 5 is installed at one end of the first electric push rod 4 and the second electric push rod 401 near the center of the base plate 1. Side plates 101 are fixedly connected to the top of both sides of the base plate 1, and the bottom of the movable plate 2 is connected to the top of the side plates 101. The sliding connection is as follows: an electric telescopic rod 201 is fixedly connected to the center of the movable plate 2; a slider 402 is installed on the outer wall of the second electric push rod 401 near the inside of the lifting frame 3; a rectangular hole 302 corresponding to the slider 402 is opened inside the lifting frame 3; and an adjusting screw 403 is provided through the top and bottom of the end of the slider 402 away from the connecting block 5; a central rod 501 is fixedly connected through the center of the inside of the connecting block 5; a rubber ring 502 is sleeved around the top and bottom of the central rod 501; and a compression bolt 503 is threaded on one side of the rubber ring 502.

[0026] like Figure 1 , Figure 2As shown, both ends of the movable plate 2 are threaded with fixing bolts 203 near the top of the side plate 101. The fixing bolts 203 penetrate the interior of the movable plate 2 and are pressed against the side plate 101. The bottom protruding end of the electric telescopic rod 201 is fixedly connected to the cleaning module 202. The cleaning module 202 is equipped with a grinding device. The top of the base plate 1 is inclined to the bottom at both sides away from the side plate 101. By rotating the pressing bolts 503, the fixing of the rubber ring 502 is released, and the position of the rubber ring 502 can be adjusted. At the same time, the rubber ring 502 can be removed and replaced with different sizes. During processing, the movable plate 2 can be moved, and the cleaning module 202 can be moved by the electric telescopic rod 201. The grinding device inside the cleaning module 202 is used to process the valve body, which is convenient for the grinding device to process valve bodies of different sizes and structures.

[0027] like Figure 3 , Figure 5 As shown, the top and bottom of the connecting block 5 are sleeved with the rubber ring 502. The inner protruding ends of the first electric push rod 4 and the second electric push rod 401 are fixedly connected to one end of the connecting block 5. The slider 402 is T-shaped, and one side of the slider 402 is slidably connected to the inside of the rectangular hole 302. The two ends of the adjusting screw 403 have opposite threads. The ends of the second electric push rod 401 and the first electric push rod 4 away from the connecting block 5 are in contact with the side wall of the side plate 101. Rotating the adjusting screw 403 causes the sliders 402 at both ends to slide along the inside of the rectangular hole 302, thereby causing the second electric push rod 401 to move. This causes the connecting block 5 at the protruding end of the second electric push rod 401 to move closer to the valve body, thereby activating the extension of the second electric push rod 401. This causes the connecting block 5 at one end of the second electric push rod 401 to move closer to the valve body, thereby causing the central rod 501 to drive the rubber ring 502 to move closer to the valve body and press it, thus achieving compression and fixation on both sides of the center of the valve body.

[0028] like Figure 3 , Figure 4 As shown, both ends of the lifting frame 3 are threaded with rotating screws 301, and the bottom of the rotating screws 301 are rotatably connected to the top of the base plate 1 through a rotating shaft. The rotating screws 301 can rotate, thereby driving the lifting frame 3 to move up and down. The lifting frame 3 then drives the first electric push rod 4 and the second electric push rod 401 to move through the slider 402, thereby causing the connecting block 5 to move accordingly, thus realizing the adjustment of the height of the rubber ring 502.

[0029] In use, the valve body to be processed can be conveniently placed between the two first electric push rods 4, and then the first electric push rods 4 are activated to move closer together, causing the connecting blocks 5 on both sides to move closer together. This, in turn, causes the rubber ring 502 to squeeze and clamp the outer wall of the valve body via the central rod 501. Then, the adjusting screw 403 is rotated according to the size of the valve body, causing the adjusting screw 403 to drive the sliders 402 at both ends to slide along the inside of the rectangular hole 302, thereby moving the second electric push rod 401. This causes the connecting block 5 at the extended end of the second electric push rod 401 to move closer to the valve body, thus activating the extension of the second electric push rod 401. This causes the connecting block 5 at one end of the second electric push rod 401 to move closer to the valve body, causing the central rod 501 to drive the rubber ring 502 to squeeze and press against the valve body, thereby clamping the valve body. The valve body is also fixed by compression on both sides of the center. When fixing valve bodies of different heights, the screw 301 can be rotated to drive the lifting frame 3 to move up and down. The lifting frame 3 then drives the first electric push rod 4 and the second electric push rod 401 to move through the slider 402, which in turn causes the connecting block 5 to move accordingly, thereby adjusting the height of the rubber ring 502. The compression bolt 503 can also be rotated to release the fixation of the rubber ring 502, further adjusting the position of the rubber ring 502. The rubber ring 502 can also be removed and replaced with different sizes. During processing, the moving plate 2 can be moved, and the cleaning module 202 can be moved through the electric telescopic rod 201. The grinding equipment inside the cleaning module 202 is used to process the valve body, making it convenient for the grinding equipment to process valve bodies of different sizes and structures.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
