Description

Technical Field

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

[0002] Flanges, also known as flange discs or flanges, are core basic components in the fields of mechanical transmission and pipeline connection. They are used for coaxial connection between shafts and for pipeline transfer at equipment inlet and outlet, such as the connection between reducer flanges and process pipelines. Through the combination structure of "flange body + gasket + bolts", they achieve detachable sealing connection and are widely used in industries such as petrochemical, power equipment, and machinery manufacturing.

[0003] In existing technologies, most flange positioning fixtures are cumbersome when positioning flanges. Current processing techniques typically involve manual positioning of flanges using components such as locating pins, locating posts, and clamping parts. This requires inserting the locating pin into the flange for positioning, then securing the locating pin with a nut, and finally clamping the flange with clamping parts. However, this positioning method also requires removing the nut to remove the locating pin during disassembly, making the operation cumbersome and inefficient in flange processing. Furthermore, different positioning components need to be changed for flanges of different diameters, making it difficult to quickly respond to the processing needs of small batches and multiple varieties. Therefore, there is an urgent need for a flange processing positioning fixture to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for flange processing, which has the advantages of convenient positioning and stable clamping. It solves the problems of manually positioning flanges with positioning pins, which requires removing nuts to take out the positioning pins during disassembly, making the operation cumbersome, and requiring different positioning components to be replaced for flanges of different diameters.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning fixture for flange processing includes a processing table and a flange. The top of the processing table is fixedly connected to a mounting base. The top of the processing table is provided with a fixing component for fixing the flange. The side wall of the mounting base is provided with a lifting component for adjusting the height of the flange.

[0008] The fixing component includes a cylinder fixedly installed on the top of the processing table. A push plate is fixedly connected to the output end of the cylinder. A support rod is fixedly connected to the side wall of the push plate. A clamping block is rotatably connected inside the support rod via a pin. An adjustment slide is opened inside the push plate, extending through to the inside of the mounting base. A positioning rod is slidably connected inside the adjustment slide.

[0009] The lifting assembly includes a placement seat fixedly connected to the side wall of the mounting base, and the placement seat has a lifting slide opening inside, with a placement rod slidably connected inside the lifting slide opening.

[0010] The beneficial effects of this utility model are:

[0011] This positioning fixture for flange processing, through the independent modular design of the fixing component and the lifting component, can quickly realize the pre-positioning, height adaptation and clamping of the flange, with short operation time. At the same time, the anti-damage structure such as rubber parts avoids damage to the flange surface.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the positioning rod is externally threaded with two nuts, which are respectively distributed on both sides of the push plate. The flange has a flange hole inside, and the positioning rod extends into the flange hole.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the two nuts lock the positioning rods on both sides of the push plate respectively, which can effectively prevent the positioning rods from moving. At the same time, the position of the positioning rods can be adjusted according to the diameter of the flange, thereby improving the versatility of the tooling.

[0015] Furthermore, a transmission rod is rotatably connected to the side wall of the mounting base, and the end of the transmission rod away from the mounting base is rotatably connected to the clamping block.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the support rod is raised to transmit the external driving force to the clamping block, driving the clamping block to rotate around the transmission rod, thereby clamping and fixing the flange.

[0017] Furthermore, a connecting plate is fixedly connected to one end of the placement rod that extends to the other side of the placement seat. An adjustment hole is provided inside the placement seat. A threaded rod extending into the adjustment hole is threadedly connected inside the connecting plate. A knob is fixedly connected to the outside of the threaded rod.

[0018] The beneficial effect of adopting the above-mentioned further solution is that rotating the knob drives the threaded rod to rotate, causing it to disengage from the adjustment hole, thereby enabling the connecting plate and the placement rod to move up and down along the lifting slide. This is suitable for height adaptation of small batches of multi-specification flanges and improves the versatility of tooling.

[0019] Furthermore, there are two placement rods, and each placement rod is covered with a rubber sleeve.

[0020] The advantages of adopting the above-mentioned further solution are that the two placement rods support the flange from both sides of the bottom, resulting in better stability; the rubber sleeve increases the friction with the flange, preventing slippage during processing; and the elastic material buffers the pressure, preventing the bottom surface of the flange from being damaged.

[0021] Furthermore, the flange is placed on the top of two placement rods, and a rubber pad is fixedly connected to the side of the clamping block near the mounting base. There are two clamping blocks.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the flange is supported by the placement rod, the clamping blocks clamp synchronously, and the rubber gasket prevents the clamping blocks from directly squeezing the side of the flange, causing scratches or deformation, thus ensuring surface quality.

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the embodiments, by Figure 1-5This invention discloses a positioning fixture for flange processing. The fixture includes a processing table 1 and a flange 2. A mounting base 3 is fixedly connected to the top of the processing table 1. A fixing assembly for fixing the flange 2 is provided at the top of the processing table 1. A lifting assembly for adjusting the height of the flange 2 is provided on the side wall of the mounting base 3. The fixing assembly includes a cylinder 4 fixedly installed at the top of the processing table 1. The cylinder 4 is a linear drive element (such as an SC series standard cylinder) in the prior art, and its extension stroke is controlled by a solenoid valve. A push plate 5 is fixedly connected to the output end of the cylinder 4. A support rod 6 is fixedly connected to the side wall of the push plate 5. A clamping block 7 is rotatably connected inside the support rod 6 via a pin. A transmission rod 14 is rotatably connected to the side wall of the mounting base 3. The end of the transmission rod 14 away from the mounting base 3 is rotatably connected to the clamping block 7. A rubber pad is fixedly connected to the side of the clamping block 7 closest to the mounting base 3. There are two clamping blocks 7.

[0031] In this embodiment, in actual use, the lifting support rod 6 transmits the external driving force to the clamping block 7, driving the clamping block 7 to rotate around the transmission rod 14, thereby clamping and fixing the flange with the clamping block 7. The rubber pad prevents the clamping block 7 from directly squeezing the side of the flange, causing scratches or deformation, and ensuring surface quality.

[0032] Specifically, refer to Figure 5 The push plate 5 has an adjustment slide 8 that extends through the mounting base 3. The adjustment slide 8 is slidably connected to a positioning rod 9. The positioning rod 9 is threaded with two nuts 10 on its outside. The two nuts 10 are distributed on both sides of the push plate 5. The flange 2 has a flange hole inside, and the positioning rod 9 extends into the flange hole.

[0033] In this embodiment, in actual use, the cylinder 4 pushes the push plate 5 to move, and the positioning rod 9 is inserted into the flange hole when the push plate 5 moves, so as to achieve radial pre-positioning of the flange. Tightening the nuts 10 on both sides can lock the positioning rod 9 to prevent it from shifting due to vibration. If it is necessary to adapt to flanges of different diameters, the positioning rod 9 can be slid along the adjusting slide 8 to adjust its alignment with the flange hole, thereby improving the versatility of the tooling.

[0034] Specifically, refer to Figure 4 The lifting assembly includes a placement seat 11 fixedly connected to the side wall of the mounting base 3. The placement seat 11 has a lifting slide 12 inside. A placement rod 13 is slidably connected inside the lifting slide 12. A connecting plate 15 is fixedly connected to one end of the placement rod 13 that extends through to the other side of the placement seat 11. An adjustment hole 18 is opened inside the placement seat 11. A threaded rod 16 extending into the adjustment hole 18 is threadedly connected inside the connecting plate 15. A knob 17 is fixedly connected to the outside of the threaded rod 16. There are two placement rods 13. A rubber sleeve is fitted on the outside of the placement rods 13. A flange 2 is placed on the top of the two placement rods 13.

[0035] In this embodiment, in actual use, the two placement rods 13 support the flange 2 from both sides of the bottom, resulting in better stability. The rubber sleeve increases the friction with the flange 2 to prevent slippage during processing. At the same time, the elastic material buffers the pressure and prevents the bottom surface of the flange 2 from being damaged. Rotating the knob 17 drives the threaded rod 16 to rotate, causing it to disengage from the adjustment hole 18. This allows the connecting plate 15 and the placement rods 13 to move up and down along the lifting slide 12. This is suitable for height adaptation of small batches of multi-specification flanges. The diameter of the flange 2 needs to be adapted to the adjustment hole 18, improving the versatility of the tooling.

[0036] Working principle:

[0037] Take the flange 2 to be processed. According to the diameter of the flange 2, turn the knob 17 to drive the threaded rod 16 to rotate, so that it is disengaged from the adjustment hole 18. Then, the connecting plate 15 and the placement rod 13 can be moved along the lifting slide 12. By adjusting the height of the placement rod 13, it can be adapted to flanges 2 of different diameters. At this time, the bottom end of the flange 2 is located inside the placement seat 11. By aligning the flange hole of the flange 2 with the adjustment slide 8, the cylinder 4 pushes the push plate 5 to move horizontally towards the mounting seat 3. The push plate 5 drives the clamping block 7 to rotate around the transmission rod 14 through the support rod 6. At the same time, the positioning rod 9 is inserted into the flange hole of the flange 2 synchronously with the push plate 5 to achieve radial pre-positioning. When the push plate 5 moves to the limit position, the rubber pad of the clamping block 7 contacts the side of the flange 2 and gradually applies a uniform clamping force.
