Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and in particular to a feeding device for a laser cutting machine used in the production of fire hydrant valves. Background Technology

[0002] Fire hydrant valves are core safety components of fire water supply systems and building fire protection facilities. The machining precision and surface quality of key components such as valve bodies, valve covers, valve discs, and flanges directly determine the sealing performance, opening and closing reliability, and service life of fire hydrants, thus affecting public fire safety. Due to limitations in the valve manufacturing process, various usage scenarios will be encountered during processing, not just the one mentioned below. More specifically, laser cutting machines are often used to cut the raw materials required for production.

[0003] Currently, when cutting common valve and pipe fitting raw materials, the position of the raw materials is usually manually positioned and fixed, and then a laser cutting machine is used to cut the raw materials. The cutting process requires manual intervention, which not only consumes a lot of manpower, but also the gas generated during cutting can cause harm to the human body. To address this, we have proposed a feeding device for a laser cutting machine in the production of fire hydrant valves. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a feeding device for a laser cutting machine used in the production of fire hydrant valves. This solves the current problem that when common valve and pipe fitting raw materials are cut, the position of the raw materials is usually manually positioned and fixed before a laser cutting machine is used to cut them. This process requires manual intervention, which not only consumes a lot of manpower but also causes harm to the human body due to the gas generated during cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A feeding device for a laser cutting machine used in the production of fire hydrant valves includes a laser cutting machine body, a control center on one side of the laser cutting machine body, a processing center on one side of the control center, a pushing component mounted on the top of the laser cutting machine body, a rotating inner support mechanism mounted on one side of the top of the pushing component, and a support positioning mechanism mounted on one side of the control center. The rotating inner support mechanism includes a base plate, a support plate, a bending plate, an inner support assembly, and a rotating assembly. The support plate is fixedly installed on the top side of the pushing assembly. The base plate is fixedly connected to one side of the support plate. The bending plate is fixedly connected to the top side of the support plate. The inner support assembly is provided on one side of the bending plate. The rotating assembly is installed on one side of the inner support assembly.

[0006] Preferably, the inner support assembly includes a cylinder, a long rod, a sleeve rod, an active rotating rod, a driven rotating rod, and a stop plate. The cylinder is fixedly installed on one side of the bending plate. The front end of the cylinder's output end is rotatably connected to the long rod via a bearing. A sleeve rod is provided on the outside of the long rod. The sleeve rod is rotatably connected to the support plate via a bearing. Multiple active rotating rods are provided on the outside of one end of the long rod. Multiple driven rotating rods are correspondingly provided on the outside of the sleeve rod. The stop plate is rotatably connected to one end of both the active and driven rotating rods.

[0007] The technical effect of adopting the above-mentioned further solution is that when the other end of the control part is installed, specifically, the other end of the control part is sleeved on the outside of multiple abutment plates. By activating the cylinder, the active rotating rod will be pushed by the long rod. Under the action of this force, the active rotating rod and the driven rotating rod will work together to adjust the position of the abutment plate so that the abutment plate can be tightly attached to the inner wall of the part, thus realizing the fixation of control parts of different diameters.

[0008] Preferably, the rotating assembly includes a drive motor, a reduction sprocket set, a key block, and a keyway. The drive motor is fixedly installed on the top side of the base plate, and the output end of the drive motor is fixedly connected to the reduction sprocket set. The key block is fixedly connected to the outside of the long rod, and a keyway corresponding to the key block is opened on the inner side of the sleeve rod. The driven gear of the reduction sprocket set is fixedly sleeved on the outside of one end of the sleeve rod.

[0009] The technical effect of adopting the above-mentioned further solution is that the drive motor can drive the sleeve rod to rotate through the reduction sprocket set, and under the drive of the key block and keyway, the abutment plate and the parts can rotate, so that the machining center can cut the controlled parts.

[0010] Preferably, the support and positioning mechanism includes a support component and a stabilizing component. The support component is installed on the upper surface of the laser cutting machine body near the control center, and the stabilizing component is installed above the support component.

[0011] The technical effect of adopting the above-mentioned further solution is that it can fix the end of the control part near the machining center, and at the same time, it can make the two ends of the control part on the same horizontal plane.

[0012] Preferably, the support assembly includes a hydraulic cylinder, an upper connecting plate, an arc-shaped surface, and a ball bearing. The hydraulic cylinder is installed on the upper surface of the laser cutting machine body near the control center. The upper connecting plate is fixedly connected above the output end of the hydraulic cylinder. An arc-shaped surface is provided in the middle of the upper connecting plate, and a plurality of ball bearings are installed on the inner side of the arc-shaped surface.

[0013] The technical effect of adopting the above-mentioned further solution is as follows: First, place one end of the control part inside the arc-shaped surface at the top of the upper connecting plate, and then start the hydraulic cylinder. The hydraulic cylinder adjusts the height of the control part so that both ends of the control part are on the same horizontal plane, and the other end of the control part can be fixed.

[0014] Preferably, the stabilizing component includes a fixed plate, an electric push rod, a lower connecting plate, cylindrical rods, and ball bearings. The fixed plate is fixedly connected to one side of the control center. An electric push rod is fixedly installed on the top of the fixed plate. The lower connecting plate is fixedly installed at the bottom output end of the electric push rod. Multiple cylindrical rods are fixedly connected to the bottom of the lower connecting plate. Ball bearings are rotatably installed at the bottom of each of the multiple cylindrical rods. The stabilizing component also includes guide rods. The guide rods are fixedly installed on both sides of the top of the lower connecting plate, and the guide rods are slidably engaged with the fixed plate.

[0015] The technical effect of adopting the above-mentioned further solution is: when the electric push rod is turned on, the electric push rod drives the lower connecting plate to move downward until the second ball at the bottom of the cylindrical rod is in close contact with the surface of the control part, the control part can be positioned. The first ball and the second ball can fix the control part while reducing the friction of the control part when it rotates.

[0016] Preferably, the pushing assembly includes a mounting box, a motor, a sprocket assembly, a threaded rod, an adjusting plate, and a moving plate. The mounting box is fixedly installed on the top side of the laser cutting machine body. Two adjusting plates are fixedly connected to one side of the mounting box. The motor is fixedly installed inside the mounting box. A sprocket assembly is fixedly connected to the output end of the motor. Threaded rods are fixedly connected to both sides of the sprocket assembly. A moving plate is threadedly connected to the outside of the threaded rod. The moving plate is fixedly connected to the support plate. Both ends of the threaded rod are rotatably connected to the adjusting plate through bearings.

[0017] The technical effect of adopting the above-mentioned further solution is that the motor can drive the sprocket assembly to rotate, thereby driving the threaded rod to rotate. At this time, the moving plate moves closer to the machining center under the drive of the threaded rod, which can realize the fixed-distance conveying of the controlled parts. During the conveying process, the first and second balls can also play a lubricating role on the controlled parts, reducing the friction between them and the arc surface.

[0018] (a) Beneficial effects Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a support and positioning mechanism, first places one end of the control part inside the arc-shaped surface at the top of the upper connecting plate, then activates the hydraulic cylinder to adjust the height of the control part so that both ends of the control part are on the same horizontal plane, thus fixing the other end of the control part. Then, the electric push rod is activated, which drives the lower connecting plate to move downward until the second ball bearing at the bottom of the cylindrical rod is in close contact with the surface of the control part, thus positioning the control part. The first and second balls can fix the control part while reducing friction during the rotation of the control part.

[0019] 2. This invention, by setting up a rotating inner support mechanism and activating the cylinder, causes the active rotating rod to be pushed by the long rod. Under the action of this force, the active rotating rod and the driven rotating rod work together to adjust the position of the abutment plate so that the abutment plate can be tightly attached to the inner wall of the part. This can achieve the fixing of parts with different diameters. The drive motor can drive the sleeve rod to rotate through the reduction sprocket set. Under the drive of the key block and keyway, the abutment plate and the part can be rotated so that the machining center can cut the parts.

[0020] 3. By setting up a pushing component, after the cutting is completed, the motor can drive the sprocket group to rotate, thereby driving the threaded rod to rotate. At this time, the moving plate moves closer to the machining center under the drive of the threaded rod, which can realize the fixed-distance transportation of the control parts. During the transportation process, the first and second balls can also play a lubricating role on the control parts, reducing the friction between them and the arc surface.

[0024] The technical solution in this application embodiment effectively solves the current problem that, when cutting common valve and pipe fitting raw materials, the position of the raw material is usually manually positioned and fixed before a laser cutting machine is used to cut it. This process requires manual intervention, which not only consumes a lot of manpower but also causes harm to the human body due to the gases generated during cutting. The overall approach is as follows: like Figures 1 to 8 In view of the problems existing in the prior art, the present invention provides a feeding device for a laser cutting machine for fire hydrant valve production, including a laser cutting machine body 1, a control center 12 is provided on one side of the laser cutting machine body 1, a processing center 11 is provided on one side of the control center 12, a pushing component 13 is installed on the top of the laser cutting machine body 1, a rotating inner support mechanism 2 is installed on one side of the top of the pushing component 13, and a support positioning mechanism 3 is installed on one side of the control center 12. The rotating inner support mechanism 2 includes a base plate 21, a support plate 22, a bending plate 23, an inner support assembly 24, and a rotating assembly 25. The support plate 22 is fixedly installed on the top side of the pushing assembly 13. The base plate 21 is fixedly connected to one side of the support plate 22. The bending plate 23 is fixedly connected to the top side of the support plate 22. The inner support assembly 24 is provided on one side of the bending plate 23. The rotating assembly 25 is installed on one side of the inner support assembly 24.

[0025] Specifically, the inner support assembly 24 includes a cylinder 241, a long rod 242, a sleeve rod 243, an active rotating rod 244, a driven rotating rod 245, and an abutment plate 246. The cylinder 241 is fixedly installed on one side of the bending plate 23. The front end of the output end of the cylinder 241 is rotatably connected to the long rod 242 through a bearing. The sleeve rod 243 is provided on the outside of the long rod 242. The sleeve rod 243 is rotatably connected to the support plate 22 through a bearing. Multiple active rotating rods 244 are provided on the outside of one end of the long rod 242. Multiple driven rotating rods 245 are correspondingly provided on the outside of the sleeve rod 243. The abutment plate 246 is rotatably connected to one end of the active rotating rod 244 and the driven rotating rod 245.

[0026] By adopting the above technical solution, the other end of the control part is sleeved on the outside of multiple abutment plates 246. By activating the cylinder 241, the active rotating rod 244 will be pushed by the long rod 242. Under the action of this force, the active rotating rod 244 and the driven rotating rod 245 work together to adjust the position of the abutment plate 246 so that the abutment plate 246 can be tightly attached to the inner wall of the part, thus realizing the fixation of control parts of different diameters.

[0027] Specifically, the rotating assembly 25 includes a drive motor 251, a reduction sprocket set 252, a key block 253, and a keyway 254. The drive motor 251 is fixedly installed on the top side of the base plate 21. The output end of the drive motor 251 is fixedly connected to the reduction sprocket set 252. The key block 253 is fixedly connected to the outside of the long rod 242. The inner side of the sleeve rod 243 is provided with a keyway 254 corresponding to the key block 253. The driven gear of the reduction sprocket set 252 is fixedly sleeved on the outside of one end of the sleeve rod 243.

[0028] By adopting the above technical solution, the drive motor 251 can drive the sleeve rod 243 to rotate through the reduction sprocket set 252. Under the drive of the key block 253 and the keyway 254, the abutment plate 246 and the part can rotate, so that the machining center 11 can cut the controlled part.

[0029] In this embodiment, the other end of the control part is sleeved on the outside of multiple abutment plates 246. By activating the cylinder 241, the active rotating rod 244 will be pushed by the long rod 242. Under the action of this force, the active rotating rod 244 and the driven rotating rod 245 work together to adjust the position of the abutment plate 246 so that the abutment plate 246 can be tightly attached to the inner wall of the part, thus fixing control parts of different diameters. The drive motor 251 can drive the sleeve rod 243 to rotate through the reduction sprocket set 252. Under the drive of the key block 253 and the keyway 254, the abutment plate 246 and the part can rotate, so that the machining center 11 can cut the control part.

[0030] like Figures 1 to 8The support and positioning mechanism 3 includes a support component 31 and a stabilizing component 32. The support component 31 is installed on the upper surface of the laser cutting machine body 1 near the control center 12. The stabilizing component 32 is installed above the support component 31. The support component 31 includes a hydraulic cylinder 311, an upper connecting plate 312, an arc surface 313, and ball bearings 314. The hydraulic cylinder 311 is installed on the upper surface of the laser cutting machine body 1 near the control center 12. The upper connecting plate 312 is fixedly connected above the output end of the hydraulic cylinder 311. An arc surface 313 is provided in the middle of the upper connecting plate 312. Multiple ball bearings 314 are installed on the inner side of the arc surface 313.

[0031] By adopting the above technical solution, one end of the control part is first placed inside the arc-shaped surface 313 at the top of the upper connecting plate 312, and then the hydraulic cylinder 311 is activated. The hydraulic cylinder 311 adjusts the height of the control part so that both ends of the control part are on the same horizontal plane, and the other end of the control part can be fixed.

[0032] Specifically, the stabilizing component 32 includes a fixed plate 321, an electric push rod 322, a lower connecting plate 323, cylindrical rods 325, and ball bearings 326. The fixed plate 321 is fixedly connected to one side of the control center 12. The electric push rod 322 is fixedly installed on the top of the fixed plate 321. The lower connecting plate 323 is fixedly installed at the bottom output end of the electric push rod 322. Multiple cylindrical rods 325 are fixedly connected to the bottom of the lower connecting plate 323. Ball bearings 326 are rotatably installed at the bottom of each of the multiple cylindrical rods 325. The stabilizing component 32 also includes a guide rod 324. The guide rod 324 is fixedly installed on both sides of the top of the lower connecting plate 323, and the guide rod 324 is slidably engaged with the fixed plate 321.

[0033] By adopting the above technical solution, the electric push rod 322 is activated, and the electric push rod 322 drives the lower connecting plate 323 to move downward until the second ball 326 at the bottom of the cylindrical rod 325 is in close contact with the surface of the control part, so that the control part can be positioned. The first ball 314 and the second ball 326 can fix the control part while reducing the friction of the control part when it rotates.

[0034] Specifically, the drive assembly 13 includes a mounting box 131, a motor 132, a sprocket assembly 133, a threaded rod 134, an adjusting plate 135, and a moving plate 136. The mounting box 131 is fixedly installed on one side of the top of the laser cutting machine body 1. Two adjusting plates 135 are fixedly connected to one side of the mounting box 131. The motor 132 is fixedly installed inside the mounting box 131. The output end of the motor 132 is fixedly connected to the sprocket assembly 133. Threaded rods 134 are fixedly connected to both sides of the sprocket assembly 133. The moving plate 136 is threadedly connected to the outside of the threaded rod 134. The moving plate 136 is fixedly connected to the support plate 22. The two ends of the threaded rod 134 are rotatably connected to the adjusting plate 135 through bearings.

[0035] By adopting the above technical solution, after the cutting is completed, the motor 132 can drive the sprocket group 133 to rotate, thereby driving the threaded rod 134 to rotate. At this time, the moving plate 136 moves closer to the machining center 11 under the drive of the threaded rod 134, which can realize the fixed-distance transport of the control parts. During the transport process, the first ball 314 and the second ball 326 can also play a lubricating role on the control parts, reducing the friction between them and the arc surface 313.

[0036] In this embodiment, during use: First, place one end of the control part inside the arc-shaped surface 313 at the top of the upper connecting plate 312. Then, activate the hydraulic cylinder 311 to adjust the height of the control part so that both ends of the control part are on the same horizontal plane, thus fixing the other end of the control part. Activate the electric push rod 322, which drives the lower connecting plate 323 downwards until the ball bearing 326 at the bottom of the cylindrical rod 325 is in close contact with the surface of the control part, thus positioning the control part. 314 and ball bearing 326 can fix the control part while reducing the friction of the control part during rotation. After cutting, the motor 132 can drive the sprocket group 133 to rotate, thereby driving the threaded rod 134 to rotate. At this time, the moving plate 136 moves closer to the machining center 11 under the drive of the threaded rod 134, which can realize the fixed distance transportation of the control part. During the transportation process, ball bearing 314 and ball bearing 326 can also lubricate the control part and reduce the friction between it and the arc surface 313.

[0037] Working principle: In use, first place one end of the control part inside the arc-shaped surface 313 at the top of the upper connecting plate 312, then activate the hydraulic cylinder 311. The hydraulic cylinder 311 adjusts the height of the control part so that both ends of the control part are on the same horizontal plane, thus fixing the other end of the control part. Specifically, when installing the other end of the control part, place it over the outside of multiple abutment plates 246. By activating the cylinder 241, the active rotating rod 244 will be pushed by the long rod 242. Under this force, the active rotating rod 244, together with the driven rotating rod 245, adjusts the position of the abutment plate 246 until it is tightly against the inner wall of the part, thus fixing control parts of different diameters. Then, activate the electric push rod 322, which drives the lower connecting plate 323 downwards until the bottom of the cylindrical rod 325... When ball 2 326 is in close contact with the surface of the control part, the control part can be positioned. Ball 1 314 and ball 2 326 can fix the control part while reducing friction during rotation. The drive motor 251 can drive the sleeve rod 243 to rotate through the reduction sprocket set 252. Under the drive of the key block 253 and keyway 254, the abutment plate 246 and the part can rotate, so that the machining center 11 can cut the control part. At the same time, after the cutting is completed, the motor 132 can drive the sprocket set 133 to rotate, thereby driving the threaded rod 134 to rotate. At this time, the moving plate 136 moves closer to the machining center 11 under the drive of the threaded rod 134, which can realize the fixed distance transport of the control part. During the transport process, ball 1 314 and ball 2 326 can also lubricate the control part and reduce the friction between it and the arc surface 313.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
