Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and specifically relates to a clamping fixture for processing flange positioning holes. Background Technology

[0002] A flange is a disc-shaped metal connector. Its core function is to enable detachable connection of components such as pipes, valves, and equipment through the surrounding bolt holes and the mating of the sealing gasket. It has structural stability and sealing performance. According to the structure, it can be divided into various types such as flat welding, butt welding, and threaded. The sealing surface design includes flat, concave and convex shapes to adapt to different media environments.

[0003] In existing technology, the flange is usually placed on a support platform, and then pressed onto the support platform with a pressure plate. Then, a drill bit is used to drill holes in the flange through the connecting holes on the pressure plate. Since the moving distance between the pressure plate and the support platform is fixed, when loading and unloading the flange, the operator needs to hold the flange between the support platform and the pressure plate. If accidental contact occurs, it can easily cause injury to the operator's safety, and it is also inconvenient to remove the processed flange from inside the support platform. Utility Model Content

[0004] To address the issue that the fixed movement distance between the pressure plate and the support platform necessitates manually inserting the flange between the support platform and the pressure plate during flange loading and unloading, which could easily cause injury to the operator if accidentally touched, and also makes it inconvenient to remove the finished flange from inside the support platform, this invention proposes a clamping fixture for processing flange positioning holes to overcome the aforementioned technical problems in existing related technologies.

[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 clamping fixture for machining flange positioning holes, including a base plate:

[0007] The base plate is equipped with a support assembly, a clamping assembly, an ejection assembly, and a cleaning assembly.

[0008] The support assembly has its outer surface slidably disposed with respect to the interior of the base plate, so that the support assembly can move back and forth along the direction of the base plate;

[0009] The clamping assembly is fixedly installed at its bottom end to the top end of the base plate, so that the clamping assembly can move up and down along the direction of the base plate, so as to use the clamping assembly in conjunction with the support assembly to clamp and fix the flange.

[0010] The ejector assembly is fixedly connected to the inner wall of the support assembly on one side, so that the ejector assembly ejects the flange as the support assembly moves;

[0011] The cleaning component is fixedly installed inside the ejector component on one side, so that the ejector component moves along with the support component, thereby moving the cleaning component to clean the debris on the top of the base plate.

[0012] Furthermore, the support component includes a T-slot, which is formed at the top of the base plate. A T-block is slidably disposed inside the T-slot. A handle is fixedly connected to one end of the T-block, and a support platform is fixedly connected to the top of the T-block. A placement groove is formed at the top of the support platform.

[0013] Furthermore, the clamping assembly includes a guide rod, the bottom end of which is fixedly installed with the top end of the base plate. A pressure plate is slidably disposed on the outer surface of the guide rod. A through hole is opened at the top end of the pressure plate. An electric push rod is fixedly installed at the bottom end of the pressure plate. The bottom end of the electric push rod is fixedly installed with the top end of the base plate.

[0014] Furthermore, the ejection assembly includes an inclined plate, one side of which is fixedly connected to the inner wall of the support platform. A support frame is fixedly connected to the bottom end of the inclined plate, and a support cylinder is fixedly connected to the top end of the support frame. A top cylinder is slidably disposed on the outer surface of the support cylinder, and a tension spring is fixedly connected inside the top cylinder. One end of the tension spring is fixedly connected to the top end of the support frame.

[0015] Furthermore, the ejection assembly also includes a sliding groove and a top block. The sliding groove is opened inside the support frame. A limit rod is slidably and fixedly connected inside the sliding groove. A connecting block is slidably provided on the outer surface of the limit rod. One side of the connecting block is fixedly connected to the outer surface of the top cylinder. The bottom end of the top block is fixedly connected to the top end of the base plate.

[0016] Furthermore, the cleaning component includes a mounting slot, which is opened on one side of the inclined plate. A mounting plate is fixedly installed inside the mounting slot, and a cleaning brush is fixedly connected to the bottom end of the mounting plate.

[0017] Furthermore, a limiting groove is provided inside the sliding groove, and a limiting block is slidably arranged inside the limiting groove. One side of the limiting block is fixedly connected to one side of the connecting block.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model moves the support assembly along the direction of the base plate, so that the support assembly moves away from the base plate. At the same time, when the support assembly moves, it can drive the ejector assembly fixed on the inner wall to move, so that the ejector assembly moves upward after moving a certain distance, so that the ejector assembly can extend out of the top of the support assembly, so that the ejector assembly can push out the flange that has been processed inside the support assembly, thereby facilitating the loading and unloading of the flange.

[0020] 2. When the inclined plate is moved by the support platform, the inclined plate can move the support frame fixed at the bottom, which in turn moves the fixed limiting rod. The limiting rod then moves the connecting block that is slidably set on the outer surface. When the connecting block moves to the top surface of the top block, it can move upward along the slope opened at the top of the top block. During the upward movement of the connecting block, it can move the top cylinder fixed on one side upward, so that the flange set at the top of the top cylinder can be pushed out of the placement groove. When the top cylinder moves, it can stretch the tension spring, which facilitates the unloading of the flange. Then, the unprocessed flange is placed on the top of the top cylinder. As the support platform moves back to its original position, the tension spring can contract and stretch the tension stress, which drives the top cylinder to move downward, so that the top cylinder can carry the flange into the placement groove, which facilitates the loading and unloading of the flange.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-6 As shown, this utility model is a clamping fixture for machining flange positioning holes, including a base plate 1:

[0034] The base plate 1 is respectively equipped with a support assembly 2, a clamping assembly 3, an ejection assembly 4, and a cleaning assembly 5;

[0035] The support component 2 has its outer surface slidably disposed with the interior of the base plate 1, so that the support component 2 can move back and forth along the direction of the base plate 1;

[0036] The clamping assembly 3 is fixedly installed at its bottom end to the top end of the base plate 1 so that the clamping assembly 3 can move up and down along the direction of the base plate 1, so as to use the clamping assembly 3 to cooperate with the support assembly 2 to clamp and fix the flange.

[0037] Ejector assembly 4, one side of which is fixedly connected to the inner wall of support assembly 2, so that ejector assembly 4 ejects the flange as support assembly 2 moves;

[0038] The cleaning component 5 is fixedly installed inside the ejector component 4 on one side, so that the ejector component 4 moves along with the support component 2, thereby moving the cleaning component 5 to clean the debris on the top of the base plate 1.

[0039] In use, by pulling the support assembly 2 along the direction of the base plate 1, the support assembly 2 moves away from the base plate 1. At the same time, when the support assembly 2 moves, it can drive the ejector assembly 4 fixed on the inner wall to move. After the ejector assembly 4 moves a certain distance, it moves upward, so that the ejector assembly 4 extends out of the top of the support assembly 2. Then, the flange is placed on the top of the ejector assembly 4, and the support assembly 2 is pushed in the opposite direction to reset the ejector assembly 4. This allows the ejector assembly 4 to pull the flange into the interior of the support assembly 2. After the support assembly 2 drives the flange to reset, the clamping assembly 3 is activated to move downward, so that the bottom end face of the clamping assembly 3 fits against the top face of the flange, thereby clamping and fixing the flange for subsequent drilling processing. The cleaning assembly 5 is set up so that it can clean up the debris that falls on the top of the base plate 1 as the support assembly 2 and the ejector assembly 4 move.

[0040] This invention moves the support assembly 2 along the direction of the base plate 1, causing the support assembly 2 to move away from the base plate 1. At the same time, when the support assembly 2 moves, it can drive the ejector assembly 4 fixed on the inner wall to move, so that the ejector assembly 4 moves upward after moving a certain distance, thereby allowing the ejector assembly 4 to extend out of the top of the support assembly 2, so that the ejector assembly 4 can eject the flange that has been processed inside the support assembly 2, thus facilitating the loading and unloading of the flange.

[0041] In one embodiment, the support component 2 includes a T-slot 201, which is formed at the top of the base plate 1. A T-block 202 is slidably disposed inside the T-slot 201. A handle 203 is fixedly connected to one end of the T-block 202. A support platform 204 is fixedly connected to the top of the T-block 202. A placement groove 205 is formed at the top of the support platform 204.

[0042] By pulling the handle 203, the T-block 202 fixed on one side is moved. Since the outer surface of the T-block 202 is slidably set with the inside of the T-slot 201, and the top of the T-block 202 is fixedly connected to the bottom of the support platform 204, when the T-block 202 moves, it can drive the support platform 204 to move along the direction of the T-slot 201. This allows the support platform 204 to drive the placement slot 205 opened at the top to move, so as to cooperate with the placement slot 205 to load and unload the flange.

[0043] In one embodiment, the clamping assembly 3 includes a guide rod 301, the bottom end of which is fixedly installed with the top end of the base plate 1. A pressure plate 302 is slidably disposed on the outer surface of the guide rod 301. A through hole 303 is opened at the top end of the pressure plate 302. An electric push rod 304 is fixedly installed at the bottom end of the pressure plate 302. The bottom end of the electric push rod 304 is fixedly installed with the top end of the base plate 1.

[0044] By activating the electric push rod 304, the pressure plate 302 installed at the telescopic end is moved up and down, so that the pressure plate 302 can move along the direction of the internally slidable guide rod 301. When the pressure plate 302 moves downward, it can fit against the top of the flange inside the placement groove 205 during the movement. This allows the pressure plate 302 to clamp the flange in conjunction with the placement groove 205. The through hole 303 facilitates drilling equipment to open the top of the flange.

[0045] In one embodiment, the ejection assembly 4 includes an inclined plate 401, one side of which is fixedly connected to the inner wall of the support platform 204. A support frame 402 is fixedly connected to the bottom end of the inclined plate 401, and a support cylinder 403 is fixedly connected to the top end of the support frame 402. A top cylinder 404 is slidably disposed on the outer surface of the support cylinder 403, and a tension spring 405 is fixedly connected inside the top cylinder 404. One end of the tension spring 405 is fixedly connected to the top end of the support frame 402.

[0046] The ejection assembly 4 also includes a sliding groove 406 and a top block 407. The sliding groove 406 is opened inside the support frame 402. A limit rod 408 is slidably and fixedly connected inside the sliding groove 406. A connecting block 409 is slidably provided on the outer surface of the limit rod 408. One side of the connecting block 409 is fixedly connected to the outer surface of the top cylinder 404. The bottom end of the top block 407 is fixedly connected to the top end of the base plate 1.

[0047] When the inclined plate 401 moves along with the support platform 204, it can cause the support frame 402 fixed at the bottom to move, thereby causing the support frame 402 to move and the fixed limiting rod 408 to move. The limiting rod 408 then causes the connecting block 409, which is slidably mounted on the outer surface, to move. When the connecting block 409 moves to the top surface of the top block 407, it can move upwards along the slope of the top of the top block 407, causing the connecting block 409 to move upwards and drive the top cylinder 4 fixed on one side. 04 moves upward, allowing the top cylinder 404 to push the flange, which is fitted at the top, out of the placement groove 205. When the top cylinder 404 moves, it can stretch the tension spring 405, which facilitates the unloading of the flange. Then, the unprocessed flange is placed on the top of the top cylinder 404. As the support platform 204 returns to its original position, the tension spring 405 contracts, causing the top cylinder 404 to move downward, so that the top cylinder 404 can carry the flange into the placement groove 205, which facilitates the loading and unloading of the flange.

[0048] In one embodiment, the cleaning component 5 includes a mounting groove 501, which is located on one side of the inclined plate 401. A mounting plate 502 is fixedly installed inside the mounting groove 501, and a cleaning brush 503 is fixedly connected to the bottom end of the mounting plate 502.

[0049] The mounting slot 501 and mounting plate 502 facilitate the disassembly, maintenance, or replacement of the cleaning brush 503 fixed at the bottom of the mounting plate 502. As the inclined plate 401 moves, the debris generated by drilling holes in the flange at the top of the inclined plate 401 can be moved and fall to the top of the base plate 1. Since the cleaning surface of the cleaning brush 503 is in contact with the top of the base plate 1, when the cleaning brush 503 moves with the mounting plate 502 along with the inclined plate 401, the cleaning brush 503 can clean the debris that falls from the top of the base plate 1.

[0050] In one embodiment, for the sliding groove 406, a limiting groove 6 is formed inside the sliding groove 406, and a limiting block 7 is slidably arranged inside the limiting groove 6. One side of the limiting block 7 is fixedly connected to one side of the connecting block 409.

[0051] When the connecting block 409 moves up and down, it can drive the fixed limiting block 7 on one side to move, and the limiting block 7 moves along the direction of the limiting groove 6, so that the limiting groove 6 cooperates with the limiting block 7 to restrict the movement direction of the connecting block 409, thereby improving the stability of the connecting block 409 during the movement process.

[0052] Through the above technical solution, 1. By pulling the support component 2 along the direction of the base plate 1, the support component 2 moves away from the base plate 1. At the same time, when the support component 2 moves, it can drive the ejector component 4 fixed on the inner wall to move, so that the ejector component 4 moves upward after moving a certain distance, thereby allowing the ejector component 4 to extend out of the top of the support component 2, so that the ejector component 4 can eject the flange that has been processed inside the support component 2, thereby facilitating the loading and unloading of the flange.

[0053] 2. When the inclined plate 401 is moved by the support platform 204, the inclined plate 401 can move the support frame 402 fixed at the bottom, thereby causing the support frame 402 to move the fixed limiting rod 408. The limiting rod 408 then moves the connecting block 409 slidably mounted on the outer surface. When the connecting block 409 moves to the top surface of the top block 407, it can move upward along the slope opened at the top of the top block 407. During the upward movement, the connecting block 409 drives the top cylinder 4 fixed on one side. 04 moves upward, allowing the top cylinder 404 to push the flange, which is fitted at the top, out of the placement groove 205. When the top cylinder 404 moves, it can stretch the tension spring 405, which facilitates the unloading of the flange. Then, the unprocessed flange is placed on the top of the top cylinder 404. As the support platform 204 returns to its original position, the tension spring 405 contracts, causing the top cylinder 404 to move downward, so that the top cylinder 404 can carry the flange into the placement groove 205, which facilitates the loading and unloading of the flange.
