Description

Technical Field

[0001] The invention relates to the technical field of positioning devices, and in particular to a positioning device for welding a pipeline support. Background Art

[0002] A pipe support is a structural component used to support overhead pipes. It is usually a U-shaped structure and is welded from three sections of steel. Commonly used steels are angle steel or U-shaped steel. Before welding, the two steels need to be cut into a 45° angle at one end close to each other so that the two steels are perpendicular to each other after splicing.

[0003] At present, when operating, workers need to use measuring tools or angle gauges to mark the angle to be cut at one end of the two steels that are close to each other, and use appropriate tools (such as angle grinders or saws) to cut one end of the two steels along the marked line so that they form an angle of 45°. After that, the incisions of the two steels are aligned, and appropriate welding methods (such as arc welding or gas shielded welding) are used for welding to ensure that they are aligned and welded firmly. At the same time, the steel needs to be fixed in position using a clamp when cutting to ensure the neatness of the cutting surface. After alignment, the steel also needs to be fixed using a clamp to ensure the firmness of the welding. This results in the need to remove the steel from the fixing clamp after the cutting is completed, and to align the two steels and then fix them again with a clamp, which requires frequent disassembly and fixing of the clamp, and the actual operation is relatively troublesome.

[0039] Embodiment 1

[0040] like Figure 1-4As shown, a positioning device for pipe support welding proposed by the present invention includes a mounting plate 1; three groups of positioning components 2 are arranged on the mounting plate 1 for clamping and fixing steel materials, and the three groups of positioning components 2 are arranged in a U shape. The positioning components 2 are also used to align the cut surface of the steel materials. The positioning components 2 include a first servo motor 201, a roller 202, and a positioning seat 203. The two groups of the first servo motors 201 are both installed at the bottom of the mounting plate 1. The output end of the first servo motor 201 passes through the mounting plate 1 and is fixedly connected to the roller 202. After starting, the first servo motor 201 drives the roller 202 to rotate, thereby realizing the movement of the steel materials. The top end of the roller 202 is rotatably connected to the positioning seat 203, and the positioning seat 203 is installed on the top of the mounting plate 1 so that the roller 202 keeps rotating in place. The positioning assembly 2 also includes a slide 204, a moving frame 205, a positioning shaft 206, and a rubber sleeve 207. Two groups of the slides 204 are both opened on the mounting plate 1, and the slides 204 are arranged on the side of the support block 3 away from the roller 202. The two groups of L-shaped moving frames 205 are respectively slidably connected to the two groups of slides 204. The positioning shaft 206 is installed at the bottom of the moving frame 205, and the positioning shaft 206 moves synchronously with the moving frame 205. The rubber sleeve 207 is rotatably connected to the outer ring of the positioning shaft 206, so that the rubber sleeve 207 keeps rotating in place. The steel is arranged between the rubber sleeve 207 and the roller 202. The rubber sleeve 207 clamps the steel after moving, and the steel moves when the roller 202 rotates. The positioning assembly 2 also includes a moving block 208, a slide bar 209, a positioning plate 210, a first push rod motor 211, and a connecting plate 212. The two groups of moving blocks 208 are fixedly connected to the bottom of the two groups of moving frames 205, respectively, and the moving frames 205 move synchronously with the moving blocks 208. The two groups of moving blocks 208 are slidably connected with a slide bar 209, and the two ends of the slide bar 209 are respectively fixedly connected with a positioning plate 210 installed at the bottom of the mounting plate 1. The positions of the slide bar 209 and the positioning plate 210 are fixed, so that the moving block 208 is limited when moving, so that it moves smoothly. The first push rod motor 211 is installed at the bottom of the mounting plate 1, and the output end of the first push rod motor 211 is fixedly connected with a connecting plate 212, and the connecting plate 212 is fixedly connected between the two groups of moving blocks 208. After starting, the first push rod motor 211 drives the two groups of moving blocks 208 to move synchronously through the first push rod motor 211.

[0041] Specifically, multiple groups of support blocks 3 are installed on the top of the mounting plate 1 to support the steel. The support blocks 3 are set at positions corresponding to the positioning components 2. The top of the support blocks 3 is an arc surface, which is convenient for reducing the friction force on the steel when it moves. And the photoelectric sensor 4 is used to sense the position of the steel. When the photoelectric sensor 4 detects the end of the steel, the position of the end of the steel can be known at this time because the position of the photoelectric sensor 4 is fixed. At the same time, the first servo motor 201 is precisely controlled by the motor controller, so that the first servo motor 201 drives the roller 202 to rotate and drives the steel to move a controllable distance, which is convenient for moving the end of the steel to the cutting position.

[0042] For further information, see Figure 5 The positioning device also includes two sets of cutting mechanisms 5 installed on the mounting plate 1 for cutting steel, and the two sets of cutting mechanisms 5 are symmetrically arranged on the top of the mounting plate 1. The cutting mechanism 5 includes a fixed seat 501, a second push rod motor 502, a mounting frame 503, a second servo motor 504, and a cutting disc 505. The fixed seat 501 is installed on the top of the mounting plate 1, and the second push rod motor 502 is installed on the bottom of the fixed seat 501. The mounting frame 503 is fixedly connected to the output end of the second push rod motor 502. After the second push rod motor 502 is started, the mounting frame 503 is driven to move. The second servo motor 504 is installed in the mounting frame 503, and the second servo motor 504 moves synchronously with the mounting frame 503. The output end of the second servo motor 504 is fixedly connected to the cutting disc 505. After the second servo motor 504 is started, the cutting disc 505 is driven to rotate to cut the steel. The angle between the cutting disc 505 and the steel is 45°, so that the cutting angle is 45°, which is convenient for splicing and welding. The cutting mechanism 5 further includes a limiting rod 506, a positioning block 507, and a limiting plate 508. Two groups of limiting rods 506 are fixedly connected to the side of the mounting frame 503 away from the cutting disc 505, and the limiting rods 506 move synchronously with the mounting frame 503. The positioning block 507 is slidably sleeved on the two groups of limiting rods 506. The positioning block 507 is fixedly connected to the top of the mounting plate 1. The position of the positioning block 507 is fixed, and cooperates with the limiting rod 506 to limit the movement of the mounting frame 503, so that the movement of the mounting frame 503 is stable, thereby ensuring stable cutting. The limiting plate 508 is installed at one end of the two groups of limiting rods 506 away from the mounting frame 503, and is used to limit and prevent the mounting frame 503 from moving too far.

[0043] Furthermore, a control panel 7 is installed on the top of the mounting plate 1, and the control panel 7 is used to input operation instructions. An electrical box 8 is also provided on one side of the control panel 7 and is installed on the top of the mounting plate 1. Multiple motor controllers are installed on the side of the electrical box 8, and the electrical box 8 is used to process operation instructions and control multiple motors to work together.

[0044] In this embodiment, when welding the pipe support, three steels are placed between the rollers 202 and the rubber sleeves 207 of the three positioning components 2, and the bottom of the steel is in contact with the support block 3. The first push rod motor 211 is started, and the first push rod motor 211 contracts to drive the connecting plate 212 to move, thereby driving the two groups of moving blocks 208 to approach the side of the first push rod motor 211 under the limiting action of the slide bar 209 and the first servo motor 201, and driving the two groups of moving frames 205 to slide in the slide groove 204. At this time, the rubber sleeve 207 is close to the steel and clamps the steel between the rollers 202 and the rubber sleeve 207. At this time, the first servo motor 201 is started to drive the roller 202 to rotate, so that the steel starts to move. When the photoelectric sensor 4 senses the end of the steel, it sends a signal to the electrical box 8, and controls the first servo motor 201 to rotate a suitable number of circles through the motor controller, so that the end of the steel is just located at the cutting position. At this time, the second servo motor 504 is started to drive the cutting disc 505 to rotate at high speed, and at the same time, the second push rod motor 502 is extended to drive the mounting frame 503 to move smoothly under the limiting action of the limiting rod 506 and the positioning block 507, and at the same time, the rotating cutting disc 505 approaches the steel and cuts. After that, the first servo motor 201 is rotated in the opposite direction to make the steel away from the cutting disc 505, and the second push rod motor 502 is started to shrink and drive the cutting disc 505 to reset. Similarly, at this time, the end of another group of steel perpendicular to the previous group of steel can be cut, and the cutting angle is 45°. At this time, the first servo motors 201 in the two groups of positioning components 2 rotate in coordination, so that the ends of the two groups of steel are spliced ​​together and perpendicular to each other, which is convenient for welding operations.

[0045] Embodiment 2

[0046] like Figure 6-8As shown, based on the first embodiment, the mounting plate 1 includes a fixed plate 11 and a movable movable plate 12, a plurality of sets of fixed feet 111 are installed at the bottom of the fixed plate 11, and a plurality of sets of movable wheels 121 are installed at the bottom of the movable plate 12, so as to facilitate the movable plate 12 to move away from the fixed plate 11, thereby adjusting the width of the welded pipe support. The fixed plate 11 is provided with two groups of positioning components 2, and the two groups of positioning components 2 are arranged in an L shape, and also include an adjustment component 6 installed at the bottom of the fixed plate 11 and the movable plate 12 for driving the movable plate 12 to move, the adjustment component 6 includes a third push rod motor 601, a first synchronous plate 602, a second synchronous plate 603, a synchronous rod 604, a limit sleeve 605, and a limit plate 606. The third push rod motor 601 is installed at the bottom of the fixed plate 11, and the output end of the third push rod motor 601 is fixedly connected to the first synchronous plate 602 installed at the bottom of the movable plate 12. After starting, the first synchronous plate 602 drives the third push rod motor 601 to move, and the third push rod motor 601 drives the movable plate 12 to move synchronously. Two groups of the second synchronous plates 603 are symmetrically arranged on both sides of the first synchronous plate 602 and fixedly connected to the bottom of the movable plate 12, and the second synchronous plate 603 moves synchronously with the movable plate 12. The two groups of synchronization rods 604 are respectively fixedly connected to the side of the two groups of second synchronization plates 603 close to the fixed plate 11, and the synchronization rods 604 move synchronously with the movable plate 12 through the second synchronization plates 603. The limiting sleeve 605 fixedly connected to the bottom of the fixed plate 11 is slidably connected to the synchronization rod 604, and is used to limit the movable plate 12 when it moves, so that the movable plate 12 moves smoothly. The two groups of limiting plates 606 are respectively installed at one end of the two groups of synchronization rods 604 away from the second synchronization plate 603, and are used to limit the moving distance of the movable plate 12.

[0047] In this embodiment, after the welding of one corner of the pipe support is completed, the third push rod motor 601 is started to extend, and the movable plate 12 is driven to move through the first synchronous plate 602. At this time, the movable plate 12 moves smoothly through the limiting action of the synchronous rod 604 and the limiting sleeve 605. At this time, the position of the steel changes, thereby adjusting the width between the two groups of steel, which is convenient for welding steel pipe supports of different widths.
