Description
Technical Field
[0001] This utility model relates to the field of fixture technology, specifically to a fixture for processing stainless steel pipes. Background Technology
[0002] Stainless steel pipes are a common type of pipe material, and are used in various applications due to their high corrosion resistance and high rigidity. In the production of stainless steel pipes, it is often necessary to cut, grind and weld them. Since the outer surface of stainless steel pipes is smooth and cylindrical, it is essential to fix them during the operation. In the past, screw clamps were the main method of fixing them.
[0003] However, some existing stainless steel pipe processing fixtures are not convenient for automatically rotating the stainless steel pipe when fixing it. When the stainless steel pipe needs to be ground, after the top of the stainless steel pipe is ground, it is still necessary to manually remove the stainless steel pipe from the fixture, then flip it over and fix it back in the fixture before the bottom can be ground. This wastes a lot of time and reduces the efficiency of stainless steel pipe processing. Therefore, we propose a stainless steel pipe processing fixture to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a fixture for processing stainless steel pipes, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing stainless steel pipes, comprising a base plate, two side plates above the base plate, and round rods rotatably connected to the sides of the two side plates that are close to each other. The right end of one of the round rods on the right extends to the outside of the right side plate, and a gear is fixedly sleeved on the outside of the right side rod. A rack meshes with the rear side of the gear. A U-shaped plate is fixedly connected to the ends of the two round rods that are close to each other. A first screw is rotatably connected to the front inner wall and the rear inner wall of the U-shaped plate. A rectangular plate is threaded to the outside of the first screw. An arc-shaped clamping plate is fixedly connected to the sides of the two rectangular plates that are close to each other. A support plate and a fixing block are fixedly connected to the right side of one of the right side plates. The same second screw is rotatably connected between the support plate and the fixing block.
[0006] More preferably, a rectangular block is threadedly connected to the outer side of the second screw, and the front side of the rectangular block is fixedly connected to the rear side of the rack.
[0007] More preferably, the same first square rod is fixedly connected between the front inner wall and the rear inner wall of the U-shaped plate, the rectangular plate is slidably sleeved on the outside of the corresponding first square rod, and the two corresponding first screws are welded together at their close ends, with the threads of the two first screws rotating in opposite directions.
[0008] More preferably, a first motor is fixedly connected to the front side of the U-shaped plate, and the end of the output shaft of the first motor is fixedly connected to the front end of the corresponding first screw.
[0009] More preferably, the support plate and the fixing block are fixedly connected by the same second square rod, and the rectangular block is slidably sleeved on the outside of the second square rod.
[0010] More preferably, a second motor is fixedly connected to the top of the support plate, the output shaft end of the second motor is fixedly connected to the top end of the second screw, and two fixing plates are fixedly connected to the top of the base plate.
[0011] More preferably, two electric telescopic rods are fixedly connected to each of the two fixed plates on their adjacent sides, and the output shaft end of the electric telescopic rod is fixedly connected to the outer side of the corresponding side plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The first motor is started, and the first screw rotates to move the rectangular plate. The rectangular plate is fixed to the stainless steel tube by the arc-shaped clamp. When the top of the stainless steel tube is finished and the bottom needs to be ground, the second motor is started, and the second screw drives the rectangular block downwards. The rectangular block drives the gear to rotate via a rack, and the gear drives the U-shaped plate to rotate via a round rod. The U-shaped plate drives the stainless steel tube to rotate via the arc-shaped clamp. At this time, the bottom of the stainless steel tube can be ground. This makes it easy for the stainless steel tube processing fixture to automatically rotate the stainless steel tube, eliminating the need for manual removal, flipping, and fixing of the stainless steel tube by the fixture, saving a lot of time and improving the efficiency of stainless steel tube processing.

The right end of one of the round rods 3 on the right extends to the outside of the right side plate 2, and a gear 4 is fixedly sleeved on the outside of the right side rod 3. A rack 5 meshes with the rear side of the gear 4. A U-shaped plate 6 is fixedly connected to the ends of the two round rods 3 that are close to each other. A first screw 7 is rotatably connected to the front inner wall and the rear inner wall of the U-shaped plate 6. A rectangular plate 8 is threaded to the outside of the first screw 7. An arc-shaped clamping plate 9 is fixedly connected to the sides of the two rectangular plates 8 that are close to each other. A support plate 10 and a fixing block 11 are fixedly connected to the right side of one of the right side plates 2. The support plate 10 and the fixing block 11 are rotatably connected by the same... The second screw 12 starts the first motor 15, which rotates the first screw 7 to move the rectangular plate 8. The rectangular plate 8 is fixed to the stainless steel tube by the arc-shaped clamp 9. When the top of the stainless steel tube is finished and the bottom of the stainless steel tube needs to be ground, the second motor 17 starts the second screw 12 to move the rectangular block 13 downward. The rectangular block 13 drives the gear 4 to rotate through the rack 5. The gear 4 drives the U-shaped plate 6 to rotate through the round rod 3. The U-shaped plate 6 drives the stainless steel tube to rotate through the arc-shaped clamp 9. At this time, the bottom of the stainless steel tube can be ground. This makes it easy for the stainless steel tube processing fixture to automatically rotate the stainless steel tube without the need for manual removal of the stainless steel tube from the fixture, flipping it over and fixing it with the fixture. This saves a lot of time and improves the efficiency of stainless steel tube processing.
[0022] In this embodiment, specifically: a rectangular block 13 is threadedly connected to the outer side of the second screw 12, and the front side of the rectangular block 13 is fixedly connected to the rear side of the rack 5.
[0023] In this embodiment, specifically: the same first square rod 14 is fixedly connected between the front inner wall and the rear inner wall of the U-shaped plate 6, the rectangular plate 8 is slidably sleeved on the outside of the corresponding first square rod 14, and the two corresponding first screws 7 are welded to each other at their close ends, and the threads of the two first screws 7 are opposite.
[0024] In this embodiment, specifically: a first motor 15 is fixedly connected to the front side of the U-shaped plate 6, and the output shaft end of the first motor 15 is fixedly connected to the front end of the corresponding first screw 7;
[0025] In this embodiment, specifically: the support plate 10 and the fixing block 11 are fixedly connected by the same second square rod 16, and the rectangular block 13 is slidably sleeved on the outside of the second square rod 16;
[0026] In this embodiment, specifically: a second motor 17 is fixedly connected to the top of the support plate 10, the output shaft end of the second motor 17 is fixedly connected to the top end of the second screw 12, and two fixing plates 18 are fixedly connected to the top of the base plate 1.
[0027] In this embodiment, specifically: two electric telescopic rods 19 are fixedly connected to each other on the side of the two fixed plates 18 that are close to each other, and the output shaft end of the electric telescopic rod 19 is fixedly connected to the outer side of the corresponding side plate 2.
[0028] In operation, when the stainless steel pipe needs to be fixed, the electric telescopic rod 19 is activated. The electric telescopic rod 19 moves the corresponding side plate 2, which in turn moves the two corresponding arc-shaped clamping plates 9 to the appropriate position. The stainless steel pipe is then placed between the four arc-shaped clamping plates 9. At this time, the first motor 15 is activated, which rotates the front first screw 7. The rotation of the front first screw 7 rotates the rear first screw 7, which in turn moves the corresponding rectangular plate 8. The rectangular plate 8 slides on the outside of the corresponding first square rod 14, and the rectangular plate 8 moves the corresponding arc-shaped clamping plates 9. The two corresponding arc-shaped clamping plates 9 move closer to each other and fix the stainless steel pipe. At this point, the stainless steel pipe can be ground. After the top of the stainless steel pipe is ground, when the bottom needs to be ground, the second motor 17 is activated. The second motor 17 moves the first... The rotation of the second screw 12 causes the rectangular block 13 to move downwards. The rectangular block 13 slides on the outside of the corresponding second square rod 16. The rectangular block 13 causes the rack 5 to move downwards. Under the action of the rack 5 meshing with the gear 4, the downward movement of the rack 5 causes the gear 4 to rotate. The rotation of the gear 4 causes a round rod 3 on the right to rotate. The rotation of the round rod 3 on the right causes the U-shaped plate 6 on the right to rotate. The rotation of the U-shaped plate 6 on the right causes the stainless steel tube to rotate through the corresponding two arc-shaped clamps 9. The stainless steel tube rotates through the two arc-shaped clamps 9 on the left, causing the U-shaped plate 6 on the left to rotate, thus flipping the stainless steel tube. At this time, the bottom of the stainless steel tube can be ground. This constitutes a fixture for processing stainless steel tubes. The fixture can automatically rotate the stainless steel tube without the need for manual removal of the stainless steel tube from the fixture, flipping it, and fixing it with the fixture. This saves a lot of time and improves the efficiency of stainless steel tube processing.
