Description

Technical Field

[0001] This utility model relates to a machining fixture, specifically a ball valve hole machining fixture, belonging to the technical field of ball valve production. Background Technology

[0002] A ball valve is a type of valve whose closing element is a ball. It typically consists of a ball, a seat, a stem, and an operating mechanism. Its working principle is to rotate the ball 90 degrees so that the through hole on the ball is aligned with or perpendicular to the direction of the pipeline, thereby opening or closing the pipeline. The ball of a ball valve is usually spherical, with the channel formed in the middle of the ball. The ball is made of various materials, commonly stainless steel, copper, and cast iron. During the machining of the valve hole on the ball, a machining fixture is usually required. This fixture is a tool used to fix and position the ball. The design and use of this fixture can ensure the machining accuracy and quality of the valve hole and improve production efficiency.

[0003] Existing ball valve bore machining fixtures typically place the ball between clamping plates, fix the ball in place, and then use drilling or grinding tools to machine it. However, existing fixtures generally use bolts for fixing, which is inconvenient to operate and generates debris during machining. This debris flies everywhere and is difficult to collect and dispose of. Therefore, we provide a ball valve bore machining fixture to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a ball valve bore machining fixture, the specific technical solution of which is as follows:

[0005] A ball valve hole machining fixture includes a support plate, a rotating mechanism in the middle of the support plate, a collecting mechanism below the support plate, a support rod below the collecting mechanism, a base plate mounted on the lower part of the support rod, a lifting mechanism above the base plate, a protective plate inside the lifting mechanism, a compression ring connected to the upper end of the protective plate, the inner wall of the protective plate being slidably connected to the support plate, and a fixing mechanism above the support plate.

[0006] Preferably, the rotating mechanism includes a support block, the outer surface of which is rotatably connected to a support plate, and two retaining rings are also connected to the outer surface of the support block, the outer surfaces of which are slidably connected to the support plate.

[0007] Preferably, the outer surface of the support block is connected to two scraper rods, the lower surface of the scraper rods is slidably connected to the support plate, and a rotating rod is fixedly connected to the lower surface of the support block.

[0008] Preferably, the collection mechanism includes a collection box, the upper end of which is fixedly connected to a support plate, and a rotating plate is hinged to one side of the collection box.

[0009] Preferably, the lifting mechanism includes a telescopic rod, the lower part of which is mounted on the upper surface of the base plate, and a fixing block is connected to the telescopic end of the telescopic rod. One side of the fixing block is fixedly connected to the protective plate.

[0010] Preferably, the fixing mechanism includes a fixing plate, a support member is fixedly connected to the lower surface of the fixing plate, the lower part of the support member is fixedly connected to the collection box, and a sliding rod is slidably connected to the inner wall of the fixing plate.

[0011] Preferably, one end of the sliding rod is connected to a clamping plate, the other end of the sliding rod is rotatably connected to a roller, a tension spring is sleeved on the outer surface of the sliding rod, one end of the tension spring is fixedly connected to the clamping plate, and the other end of the tension spring is fixedly connected to a fixing plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This ball valve orifice machining fixture, through the setting of protective plates and fixing mechanisms, places the ball to be machined on the rotating mechanism. The lifting mechanism drives the protective plate to move upward, and the protective plate presses against the fixing mechanism, causing the fixing mechanism to squeeze and fix the ball, thus facilitating the fixation of the ball and achieving the effect of quick fixing and disassembly. The protective plate blocks most of the debris on the support plate, thereby avoiding the amount of debris splashing to the outside. This solves the problem of existing fixtures that generally fix the ball by tightening bolts, which is inconvenient to operate and generates debris during processing, which is difficult to collect and dispose of.

[0014] 2. This ball valve hole processing fixture is equipped with a rotating mechanism and other components. When processing is completed or the ball needs to be rotated, the protective plate is moved downwards, so that the roller is positioned at the extrusion ring. The rotating mechanism is rotated, causing the ball to rotate. At the same time, the scraper scrapes the debris on the support plate into the collection box for storage. When it is necessary to clean the debris inside the collection box, the protective plate can be moved downwards to expose the rotating plate and open it to facilitate the cleaning of the debris inside.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1-5 The system includes a support plate 1, a rotating mechanism 2 in the middle of the support plate 1, a collecting mechanism 3 below the support plate 1, a support rod 4 below the collecting mechanism 3, a base plate 5 installed below the support rod 4, a lifting mechanism 6 above the base plate 5, a protective plate 7 inside the lifting mechanism 6, a compression ring 8 connected to the upper end of the protective plate 7, and a sliding connection between the inner wall of the protective plate 7 and the support plate 1. Two fixing mechanisms 9 are located above the support plate 1. The ball to be processed is placed on the rotating mechanism 2, and the two fixing mechanisms 9 are used to fix the ball. The ball is polished from above. When the ball needs to rotate, the restriction on the ball is released. The rotating mechanism 2 can drive the ball to rotate. There are two collection mechanisms 3, which are used to collect debris. The collection mechanism 3 and the support plate 1 above it are supported by the support rod 4 and the base plate 5. The lifting mechanism 6 can drive the protective plate 7 to move up or down to protect one side of the polishing position and prevent debris from flying. At the same time, the fixing mechanism 9 fixes the ball. The protective plate 7 is made of polymethyl methacrylate material, also known as acrylic sheet, which has a certain hardness and is light-transmitting.

[0023] The rotating mechanism 2 includes a support block 201. The outer surface of the support block 201 is rotatably connected to the support plate 1. Two retaining rings 202 are also connected to the outer surface of the support block 201. The outer surface of the retaining rings 202 is slidably connected to the support plate 1. The support block 201 has a cavity inside for placing a ball. The two retaining rings 202 are located above and below the support plate 1, respectively, to limit the support block 201 and prevent it from shifting up and down.

[0024] Two scraper rods 203 are connected to the outer surface of the support block 201. The lower surface of the scraper rods 203 is slidably connected to the support plate 1. A rotating rod 204 is fixedly connected to the lower surface of the support block 201. Both scraper rods 203 are set on the upper retaining ring 202. When the support block 201 rotates, it can drive the scraper rods 203 to rotate, so that the scraper rods 203 scrape the debris on the support plate 1 into the collection mechanism 3 for collection. Twisting the rotating rod 204 can drive the support block 201 to rotate.

[0025] The collection mechanism 3 includes a collection box 301, the upper end of which is fixedly connected to the support plate 1. A rotating plate 302 is hinged to one side of the collection box 301. The collection box 301 is used to collect waste debris. Opening the rotating plate 302 can clean the waste debris inside.

[0026] The lifting mechanism 6 includes a telescopic rod 601. The lower part of the telescopic rod 601 is installed on the upper surface of the base plate 5. The telescopic end of the telescopic rod 601 is connected to a fixing block 602. One side of the fixing block 602 is fixedly connected to the protective plate 7. The telescopic rod 601 is electrically telescopic, which can drive the protective plate 7 to move up or down. The telescopic rod 601 is equipped with a locking mechanism, which can be fixed in a suitable position. This is existing technology and will not be described in detail again.

[0027] The fixing mechanism 9 includes a fixing plate 901, a support member 902 is fixedly connected to the lower surface of the fixing plate 901, the lower part of the support member 902 is fixedly connected to the collection box 301, and a sliding rod 903 is slidably connected to the inner wall of the fixing plate 901. The fixing plate 901 is fixed by the support member 902. The fixing plate 901 has a certain thickness and can restrict the sliding rod 903 to prevent the sliding rod 903 from tilting.

[0028] One end of the sliding rod 903 is connected to a clamping plate 904, and the other end of the sliding rod 903 is rotatably connected to a roller 906. A tension spring 905 is sleeved on the outer surface of the sliding rod 903. One end of the tension spring 905 is fixedly connected to the clamping plate 904, and the other end of the tension spring 905 is fixedly connected to the fixing plate 901. When there is no external force restriction, the tension spring 905 can drive the clamping plate 904 to move closer to the fixing plate 901, thereby making the two clamping plates 904 move away from each other, so as to facilitate the quick placement and removal of the ball.

[0029] The telescopic pole 601 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

[0030] In use, this utility model works as follows: The lifting mechanism 6 drives the protective plate 7 downwards, relieving it of pressure on the roller 906. Under the action of the tension spring 905, the two clamping plates 904 move away from each other, placing the ball to be processed on the support block 201. Then, the lifting mechanism 6 drives the protective plate 7 upwards, causing the compression ring 8 to compress the roller 906. The roller 906 drives the sliding rod 903 inwards, allowing it to enter the interior of the protective plate 7. The protective plate 7 holds the roller 906 in place, causing the sliding rod 903 to move the clamping plates 904 closer to the ball. The two clamping plates 904 compress and fix the ball, securing it in place. The protective plate 7 is then positioned appropriately for processing the ball from above. The generated debris splashes into the interior of the protective plate 7 and bounces back, thus preventing the debris from splashing outward. The protective plate 7 blocks most of the debris on the support plate 1. When the processing is completed or the ball needs to be rotated, the protective plate 7 is moved downward, so that the roller 906 is located at the position of the extrusion ring 8. At the same time, the fixing mechanism 9 is no longer fixed to the ball, achieving the effect of easy fixing and disassembly. The rotating mechanism 2 is rotated to drive the ball to rotate. At the same time, the scraper 203 scrapes the debris on the support plate 1 into the inside of the collection box 301 for storage. When it is necessary to clean the debris inside the collection box 301, the protective plate 7 can be moved downward to expose the rotating plate 302. The rotating plate 302 is opened to facilitate the cleaning of the debris inside.
