Description

Technical Field

[0001] This invention relates to the field of flange sleeve processing technology, specifically to a welding and machining machine for flange sleeves. Background Technology

[0002] Flange-type sleeves, also known as pipe expansion joints or pipeline expansion devices, are compensation devices for hot fluid pipelines. They are mainly used for the installation of straight pipelines and are suitable for hot water, steam, and oil-based media. Thermal expansion is compensated by the sliding movement of the outer sleeve over the sliding sleeve.

[0003] Patent CN204160183U discloses an integrated welding and machining machine for flange sleeves, comprising a welding station and a machining station. The welding station includes a pipe vibratory feeder, a first flange vibratory feeder, a second flange vibratory feeder, a tilting feeder, a welding torch support assembly, a workpiece clamping robot mechanism, a first workpiece welding rotation assembly, and a second workpiece welding rotation assembly. The machining station includes a gantry robot, a first lathe, a second machine tool, a rotation device, and a receiving device. This invention enables fully automated welding and machining of flange sleeves, improving production efficiency. While this patent addresses the aforementioned issues, it still suffers from the difficulty of achieving omnidirectional clamping of the workpiece during welding and machining. Therefore, this integrated welding and machining machine for flange sleeves is proposed to solve these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a welding and machining integrated machine for flange sleeves, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a welding and machining integrated machine for flange sleeves, comprising a machine housing, an elevation device and a feeding device disposed inside the machine housing, a welding device disposed on the top of the machine housing, a motor assembly disposed inside the machine housing, a machining mechanism disposed on the top of the elevation device, and a welding mechanism disposed on the top of the welding device. The elevation device includes a first spiral rod, a clamping block, a wheel, a drive block, a grinding wheel, a driven rod, a first spring, and a pad. The first spiral rod is disposed at the output end of the motor assembly, and the clamping block is movably connected to the outer circumferential surface of the first spiral rod. The wheel is rotatably connected to the outer wall of the clamping block, the drive block is fixedly connected to the inner wall of the clamping block, the pad is slidably connected to the inner wall of the housing, the driven rod is fixedly connected to the bottom of the pad, the grinding wheel is rotatably connected to the bottom of the driven rod, one end of the spring is fixedly connected to the top of the grinding wheel, and the other end of the spring is fixedly connected to the bottom of the clamping block. The raising device also includes a transmission rack, a rotating rod, a drive gear, a clamping rod, and a clamping plate. The transmission rack is fixedly connected to the outer wall of the pad, the rotating rod is rotatably connected to the inner wall of the clamping block, the drive gear is fixedly connected to the outer circumferential surface of the rotating rod, and the clamping rod is fixedly connected to the outer circumferential surface of the rotating rod. The plate is rotatably connected to the top of the clamping rod via a torsion spring. The drive gear meshes with the pad block. The grinding wheel is located on the movement trajectory of the drive block. The pad block is slidably connected to the inner wall of the clamping block. The workpiece to be processed is placed between the two clamping blocks. At this time, the motor unit is started to drive the screw rod to rotate. The rotation of the screw rod causes the clamping blocks to converge towards the center to clamp the workpiece. As the clamping blocks converge towards the center, the drive block moves. The drive block moves and contacts the grinding wheel, thereby squeezing the spring and driving the driven rod to move upward under the limit of the machine housing. As the clamping blocks converge towards the center, they also drive the wheel to squeeze the arc surface of the semicircular block, causing it to shrink. The driven rod moves upward. The upward movement of the pads leveles the bottom of the workpiece, ensuring the accuracy of the blank during milling and avoiding the possibility of not finding pads of suitable height during manual leveling, thus improving production efficiency. As the pads rise, they drive the transmission rack upward, which meshes with the drive gear to rotate. The rotation of the drive gear drives the clamping rod downward, which in turn moves the clamping plate downward to clamp and fix the top of the blank, reducing the possibility of the workpiece loosening during milling. At the same time, when the blank is too high, the clamping plate will adhere to the side of the blank through the torsion spring at the bottom, thus accommodating blanks of different sizes.

[0006] Preferably, the feeding device includes a fixed block, a fixed column, two springs, a semi-circular block, a pusher, a slider, a shaking spring, a conveying box, a bayonet, and two spiral rods. The fixed block is fixedly connected to the bottom of the machine housing, the fixed column is slidably connected to the inner wall of the fixed block, the semi-circular block is fixedly connected to the front part of the semi-circular block, one end of the two springs is fixedly connected to the rear part of the semi-circular block, and the other end of the two springs is fixedly connected to the front part of the fixed block. The pusher is fixedly connected to the front part of the semi-circular block, the slider is slidably connected to the inner wall of the pad block, and the shaking spring is fixedly connected to the inner wall of the slider. The second spiral rod is rotatably connected to the inner wall of the machine housing, and the feeding box is movably connected to the outer circumference of the second spiral rod. The clamp is formed on the inner wall of the feeding box. The feeding device also includes a transmission gear, a sliding port, a meshing gear, a limiting groove, and a lifting bar. The transmission gear is fixedly connected to one end of the second spiral rod. The limiting groove is formed on the inner wall of the machine housing. The sliding port is slidably connected to the inner wall of the limiting groove. The meshing gear is fixedly connected to the inner wall of the sliding port. The lifting bar is fixedly connected to the outer wall of the sliding port. The transmission gear meshes with the meshing gear, and the clamp is located on the lifting bar. On the motion trajectory, the semicircular block is located on the motion trajectory of the wheel. The material conveying box is slidably connected to the inner wall of the machine housing. The second spiral rod is connected to the motor unit via a belt pulley system. When the blank is milled, the clamping block unfolds, ending its clamping of the workpiece. At the same time, the wheel releases its constraint on the semicircular block, and the elasticity of the second spring drives the push tip forward, thereby pushing the workpiece to fall onto the shaking spring. The elasticity of the shaking spring and the weight of the workpiece itself cause the workpiece to bounce into the material conveying box. During the bouncing process, residual milling impurities on the workpiece can be shaken off, facilitating subsequent welding. Upon starting the workpiece, when it falls into the material handling box, the motor unit starts and drives the second screw rod to rotate via the pulley assembly. The rotation of the second screw rod, through the spiral groove on the circumferential surface, moves the material handling box to the right. At the same time, the rotation of the second screw rod drives the transmission gear to rotate, thereby causing the transmission gear to engage with the sliding port and slide along the limiting groove. The movement of the limiting groove causes the lifting bar to move upward. When the lifting bar moves upward and passes through the slot opened inside the material handling box, it will drive the workpiece inside to move upward. This process can automatically complete the unloading, thereby reducing the cost of manual unloading and improving production efficiency.

[0007] Preferably, the feeding device includes a fixed block, a fixed column, a second spring, a semi-circular block, a pusher, a slider, a shaking spring, a feeding box, a bayonet, and a second screw rod. The fixed block is fixedly connected to the bottom of the machine housing, the fixed column is slidably connected to the inner wall of the fixed block, the semi-circular block is fixedly connected to the front part of the semi-circular block, one end of the second spring is fixedly connected to the rear part of the semi-circular block, and the other end of the second spring is fixedly connected to the front part of the fixed block. The pusher is fixedly connected to the front part of the semi-circular block, the slider is slidably connected to the inner wall of the pad, the shaking spring is fixedly connected to the inner wall of the slider, and the screw rod... The screw rod is rotatably connected to the inner wall of the housing. The feeding box is movably connected to the outer circumference of the screw rod. The latch is formed on the inner wall of the feeding box. The feeding device also includes a transmission gear, a sliding port, a meshing gear, a limiting groove, and a lifting bar. The transmission gear is fixedly connected to one end of the screw rod. The limiting groove is formed on the inner wall of the housing. The sliding port is slidably connected to the inner wall of the limiting groove. The meshing gear is fixedly connected to the inner wall of the sliding port. The lifting bar is fixedly connected to the outer wall of the sliding port. The transmission gear meshes with the meshing gear. The latch is located on the movement trajectory of the lifting bar. The semicircular... The block is located on the movement trajectory of the wheel. The material box is slidably connected to the inner wall of the machine housing. The second screw rod is connected to the motor assembly via a pulley system. When the workpiece is lifted by the lifting bar to the bottom of the electromagnet, the attraction will attract the workpiece. The impact force of the attraction will be buffered and dissipated by the third spring. The contraction force of the third spring will drive the sliding column to move upward. The upward movement of the sliding column will drive the driving convex circle to move upward, thereby driving the L-shaped rod to move the torsion spring plate to the center to align the attracted workpiece. When the next blank begins milling, it drives the rotating rod to rotate. At the same time, the rotating rod rotates through the meshing of the bevel gear set. The driven rod rotates, squeezing and unfolding the torsion spring clamp, causing the flange-type sleeve annular part to lock inside the limiting short groove, while the flange-type sleeve cylindrical part locks inside the bottom clamping column. The moving frame contacts the electromagnetic switch on its movement path, thus turning off the electromagnet and demagnetizing it. Under the reset of the rotating rod, it prepares to attract and fix the next transferred workpiece. When there is a workpiece inside both the torsion spring clamp and the clamping column, shaking the handle causes the workpiece to rotate, avoiding the need for rotation during subsequent welding on the welding station, reducing unnecessary design losses and improving the welding efficiency of the workpiece.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This flange sleeve welding and machining integrated machine, with the cooperation of the wheel, semi-circular block, clamping plate and pad, the wheel squeezes the arc surface of the semi-circular block to shrink it, and the driven rod moves upward to drive the pad to move upward to level the bottom of the workpiece. This ensures the accuracy of the blank during milling and avoids the possibility of not being able to find a pad of the appropriate height when leveling manually, thereby improving production efficiency. At the same time, the clamping plate will be attached to the side of the blank through the torsion spring at the bottom, so as to adapt to blanks of different sizes.

[0010] 2. The welding and machining machine for this flange sleeve, with the cooperation of the limiting groove, lifting bar, material box, and bayonet, the movement of the limiting groove drives the lifting bar to move upward. When the lifting bar moves upward and passes through the bayonet inside the material box, it will drive the workpiece inside to move upward. This process can automatically complete the unloading, thereby reducing the cost of manual unloading and improving production efficiency.

[0011] 3. The welding and machining machine for this flange sleeve, with the cooperation of the torsion spring clamp, the clamping column clamp, and the throttle, allows the workpiece to rotate when there is a workpiece inside both the torsion spring clamp and the clamping column clamp. This avoids the need for rotation during subsequent welding of the welding table, reduces unnecessary design losses, and improves the welding efficiency of the workpiece. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8One embodiment of the present invention is: a welding and machining integrated machine for flange sleeves, comprising a housing 1, a raising device 2 and a feeding device 3 disposed inside the housing 1, a welding device 4 disposed on the top of the housing 1, a motor unit 5 disposed inside the housing 1, a machining mechanism disposed on the top of the raising device 2, and a welding mechanism disposed on the top of the welding device 4. The raising device 2 includes a spiral rod 201, a clamping block 202, a wheel 203, a drive block 204, a grinding wheel 205, a driven rod 206, a spring 207, and a pad 208. A screw rod 201 is located at the output end of the motor unit 5. A clamping block 202 is movably connected to the outer circumferential surface of the screw rod 201. A wheel 203 is rotatably connected to the outer wall of the clamping block 202. A drive block 204 is fixedly connected to the inner wall of the clamping block 202. A pad 208 is slidably connected to the inner wall of the housing 1. A driven rod 206 is fixedly connected to the bottom of the pad 208.

The welding and machining machine for this flange sleeve, with the cooperation of wheel 203, semi-circular block 304, clamping plate 213 and pad 208, the wheel 203 squeezes the arc surface of the semi-circular block 304 to shrink it, and the driven rod 206 moves upward to drive the pad 208 to move upward to level the bottom of the workpiece. This ensures the accuracy of the blank during milling and avoids the possibility of not being able to find the pad 208 at the appropriate height when leveling manually, thereby improving production efficiency. At the same time, the clamping plate 213 will fit against the side of the blank through the torsion spring at the bottom, thereby adapting to blanks of different sizes.

[0023] The feeding device 3 includes a fixed block 301, a fixed column 302, a second spring 303, a semi-circular block 304, a pusher tip 305, a sliding plate 306, a shaking spring 307, a conveying box 308, a bayonet 309, and a second screw rod 310. The fixed block 301 is fixedly connected to the bottom of the machine housing 1. The fixed column 302 is slidably connected to the inner wall of the fixed block 301. The semi-circular block 304 is fixedly connected to the front part of the semi-circular block 304. One end of the second spring 303 is fixedly connected to the rear part of the semi-circular block 304, and the other end of the second spring 303 is fixedly connected to... The feeding device 3 is connected to the front of the fixed block 301, the push tip 305 is fixedly connected to the front of the semi-circular block 304, the slide plate 306 is slidably connected to the inner wall of the pad block 208, the shaking spring 307 is fixedly connected to the inner wall of the slide plate 306, the second screw rod 310 is rotatably connected to the inner wall of the housing 1, the conveying box 308 is movably connected to the outer circumference of the second screw rod 310, the bayonet 309 is opened on the inner wall of the conveying box 308, and the feeding device 3 also includes a transmission gear 311, a sliding port 312, a meshing gear 313, a limiting groove 314, and a lifting bar 31. 5. The transmission gear 311 is fixedly connected to one end of the screw rod 310. The limiting groove 314 is formed on the inner wall of the housing 1. The sliding port 312 is slidably connected to the inner wall of the limiting groove 314. The meshing gear 313 is fixedly connected to the inner wall of the sliding port 312. The lifting bar 315 is fixedly connected to the outer wall of the sliding port 312. The transmission gear 311 meshes with the meshing gear 313. The locking slot 309 is located on the movement trajectory of the lifting bar 315. The semicircular block 304 is located on the movement trajectory of the wheel 203. The conveying box 308 is slidably connected to the housing. The inner wall of 1, the spiral rod 310 and the motor group 5 are connected by a belt pulley group. The welding and machining machine of this flange sleeve, with the cooperation of the limiting groove 314, lifting bar 315, material box 308 and bayonet 309, the limiting groove 314 moves to drive the lifting bar 315 to move upward. When the lifting bar 315 moves upward, it will drive the internal workpiece to move upward when it passes through the bayonet 309 opened inside the material box 308. This process can automatically complete the unloading, thereby reducing the cost of manual unloading and improving production efficiency.

[0024] Working principle: The workpiece to be processed is placed between two clamping blocks 202. The motor unit 5 is then started, driving the spiral rod 201 to rotate. The rotation of the spiral rod 201 causes the clamping blocks 202 to converge towards the center, clamping the workpiece. Simultaneously, the clamping blocks 202 converge, driving the drive block 204 to move. The drive block 204 moves and contacts the grinding wheel 205, thus compressing the spring 207 and driving the driven rod 206 to move upwards under the limit of the machine housing 1. While the clamping blocks 202 converge, they also drive the wheel 203 to compress the arc surface of the semi-circular block 304, causing it to shrink. The upward movement of the driven rod 206 causes the pad block 208 to move upwards, leveling the bottom of the workpiece. This ensures the accuracy of the workpiece during milling and avoids the possibility of not finding a suitable height for the pad block 208 during manual leveling, thereby improving production efficiency. The pad block 208 is positioned on top... While lifting, the transmission rack 209 moves upward, meshing with the drive gear 211 to rotate. The rotation of the drive gear 211 causes the clamping rod 212 to rotate downward, thereby moving the clamping plate 213 downward to clamp and fix the top of the blank, thus reducing the possibility of the workpiece loosening during milling. At the same time, when the height of the blank is too high, the clamping plate 213 will adhere to the side of the blank through the torsion spring at the bottom, thus adapting to blanks of different sizes. In this flange sleeve welding and machining integrated machine, with the cooperation of the torsion spring clamp 413, the clamping column clamp 415, and the throttle 411, when there are workpieces inside both the torsion spring clamp 413 and the clamping column clamp 415, shaking the throttle 411 causes the workpiece to rotate, avoiding the need for rotation during subsequent welding of the welding table, reducing unnecessary design losses and improving the welding efficiency of the workpiece.

[0025] When the blank is milled, the clamping block 202 unfolds, ending its grip on the workpiece. Simultaneously, the wheel 203 releases its constraint on the semicircular block 304, and the elasticity of the spring 303 pushes the push tip 305 forward, causing the workpiece to fall onto the shaking spring 307. The elasticity of the shaking spring 307 and the workpiece's own weight cause it to bounce into the conveyor box 308. During this bounce, residual milling impurities are shaken off, facilitating subsequent welding. When the workpiece falls into the conveyor box 308, the motor unit 5 starts, driving the screw rod 310 to rotate via the pulley system. When the screw rod 310 rotates, it drives the material box 308 to move to the right through the spiral groove on the circumferential surface. At the same time, the rotation of the screw rod 310 drives the transmission gear 311 to rotate, thereby driving the transmission gear 311 to engage with the transmission sliding port 312 through the meshing gear 313 and slide along the limiting groove 314. The movement of the limiting groove 314 drives the lifting bar 315 to move upward. When the lifting bar 315 moves upward, it passes through the bayonet 309 opened inside the material box 308, which will drive the workpiece inside to move upward. This process can automatically complete the unloading, thereby reducing the cost of manual unloading and improving production efficiency.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the welding device 4 includes a fixed base 401, a passive rod 402, a movable frame 403, an electromagnet 404, a spring 405, a driving convex circle 406, a sliding column 407, a torsion spring plate 408, a connecting base 409, and an L-shaped rod 410. The fixed base 401 is fixedly connected to the top of the housing 1, the passive rod 402 is rotatably connected to the top of the fixed base 401, and the movable frame 403 is fixedly connected to the top of the passive rod 402. The sliding column 407 is slidably connected to the inner wall of the movable frame 403. The electromagnet 404 is fixedly connected to the bottom of the sliding column 407. One end of the spring 405 is fixedly connected to the top of the electromagnet 404, and the other end of the spring 405 is fixedly connected to the bottom of the movable frame 403. One end of the driving convex circle 406 is fixedly connected to the top of the sliding column 407. The connecting seat 409 is fixedly connected to the outer wall of the movable frame 403. The L-shaped rod 410 is rotatably connected to the inner wall of the connecting seat 409 through a torsion spring. The torsion spring plate 408 is fixed. The welding device 4, which is fixedly connected to the bottom of the L-shaped rod 410, also includes a throttle 411, an electromagnetic switch 412, a torsion spring clamp 413, a limiting short groove 414, and a clamping column 415. The throttle 411 is slidably connected to the top of the housing 1. The torsion spring clamp 413 is rotatably connected to the outer circumference of the throttle 411 via a torsion spring. The electromagnetic switch 412 is located on the top of the torsion spring clamp 413. The limiting short groove 414 is formed on the inner wall of the torsion spring clamp 413. The clamping column 415 is rotatably connected to the throttle 411 via a torsion spring. The outer circumference of the casing 1 has a groove on the top. The throttle 411 is slidably connected inside the groove. The L-shaped rod 410 is located on the movement trajectory of the drive convex circle 406. With the cooperation of the torsion spring clamp 413, the clamping column clamp 415 and the throttle 411, when there are workpieces inside both the torsion spring clamp 413 and the clamping column clamp 415, the throttle 411 is shaken to make the workpiece rotate, avoiding the need for rotation during subsequent welding of the welding station, reducing unnecessary design losses and improving the welding efficiency of the workpiece.

[0027] Working principle: When the workpiece is lifted by the lifting bar 315 to the bottom of the electromagnet 404, the attraction will attract the workpiece. The impact force of the attraction will be buffered and dissipated by the spring 405. The contraction force of the spring 405 will drive the sliding column 407 to move upward. The upward movement of the sliding column 407 will drive the driving cam 406 to move upward, thereby driving the L-shaped rod 410 to move the torsion spring plate 408 towards the center to align the attracted workpiece. When the next blank begins milling, it drives the rotating rod 210 to rotate. At the same time, the rotation of the rotating rod 210 will drive the driven rod 402 to rotate through the meshing of the bevel gear set, thereby squeezing and unfolding the torsion spring clamp 41. 3. The flange sleeve annular part is locked inside the limiting short groove 414, while the flange sleeve cylindrical part is locked inside the bottom clamping column 415. The moving frame 403 will contact the electromagnetic switch 412 on the movement path, thereby turning off the electromagnet 404 and demagnetizing it. Under the reset of the rotating rod 210, it will be reset to prepare to attract and fix the next transmitted workpiece. When there is a workpiece inside both the torsion spring clamp 413 and the clamping column 415, the throttle handle 411 is shaken to make the workpiece rotate, avoiding the need for rotation during subsequent welding of the welding station, reducing unnecessary design losses and improving the welding efficiency of the workpiece.
