Description

Technical Field

[0001] The present invention relates to the technical field of gantry production equipment, and in particular to an automated production device for an ETC gantry. Background Art

[0002] The ETC gantry is the core facility of the highway's electronic toll collection system. It enables rapid vehicle passage and accurate billing through highly integrated intelligent technology. The ETC gantry is mainly composed of welded steel pipes of different sizes, and its production and manufacturing are mainly manual.

[0003] After searching, the Chinese patent publication number CN116967719A discloses an automated production device for an ETC gantry and its production, including a frame, a punch and a lifting cylinder. An adjustment plate is slidably provided on the frame, and the punch is arranged on the adjustment plate; racks are symmetrically provided on both sides of the adjustment plate, and the frame is provided with adjusting gears, and the symmetrically arranged adjusting gears are connected through a transmission shaft, and the transmission shaft is provided with a first gear; an adjusting motor is provided on the frame, and a second gear is provided on the adjusting motor; a heating ring for heating the steel pipe is provided on the punch; a lifting plate is provided on the lifting cylinder, and a clamping cylinder for clamping the steel pipe is provided on the lifting cylinder, and a first button matching the lifting plate is provided on the cylinder body of the lifting cylinder, and the first button is electrically connected to the adjusting motor.

[0004] The above patent has the following deficiencies: when the above device is performing flange welding, it only places the flange on the tapered end of the pipe fitting, and then drives the flange to move downward through the adjusting plate. After the forming block clamps the steel pipe at the punch, the second electromagnet is adsorbed by the magnetic block, and then the forming block is reset. The second electromagnet pulls the magnetic block to move the welding gun to the connection between the formed steel pipe and the flange for welding. At the same time, the third button controls the rotating motor to drive the punch to rotate one circle through the PLC controller, so that the steel pipe and the flange are completely welded and formed. However, when in use, the rotating motor drives the punch to rotate, thereby driving the formed pipe fitting to rotate. The punch and the pipe fitting are not one-piece structural parts, and there is a gap between the contact surfaces of the punch and the pipe fitting. When the flange and the pipe fitting are driven to rotate, the rotation angle of the pipe fitting and the punch rotation angle will be out of sync, and the welding head will repeatedly weld the connection between the flange and the pipe fitting. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an automated production device for an ETC gantry.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An automated production device for an ETC gantry, comprising a frame base, and also comprising: a rotating frame rotating on the frame base, at least two workstation mechanisms for vertically restraining pipe fittings being arranged around the rotating frame and equidistantly; a grinding assembly located above one of the workstation mechanisms, the grinding assembly being used to rub the edge of a tapered end of the pipe fitting and remove burrs on the pipe fitting; and a welding assembly located above another of the workstation mechanisms, the welding assembly being used to weld a flange to the tapered end of the pipe fitting.

[0007] Preferably: a bracket 1 is connected to one side of the frame base, a rotating shaft is rotatably connected between the bracket 1 and the frame base, the rotating frame is connected to the rotating shaft, a driving motor is installed on the bracket 1, and the output end of the driving motor is connected to one end of the rotating shaft 1.

[0008] Furthermore: the work station mechanism includes a connecting rod extending radially along the rotating frame, a work station plate located on the end of the connecting rod away from the rotating frame, and a member arranged on the work station plate and used to clamp the pipe fitting; the bottom of the work station plate is connected to a load-bearing plate that supports the bottom of the pipe fitting, a sliding track is fixedly connected to the frame base, the load-bearing plate is slidably connected to the sliding track, and a limit ring consistent with the diameter of the pipe fitting is bolted to the side of the load-bearing plate facing the pipe fitting.

[0009] On the basis of the above scheme: the clamping member is composed of a clamping cylinder installed on a work station plate and an arc-shaped clamping plate connected to the movable end of the clamping cylinder, and at least two clamping cylinders are arranged on the work station plate.

[0010] As a further solution of the present invention: the grinding assembly includes a bracket 2 connected to the frame base, a telescopic rod 1 installed on the bracket 2, a lifting frame connected to the movable end of the telescopic rod 1, a grinding piece rotatably connected to one end of the lifting frame and used to grind the pipe wall at the end of the pipe fitting, and a motor 1 that drives the grinding piece to operate.

[0011] At the same time, the grinding piece includes an annular groove plate with a friction groove facing the pipe, a grinding block arranged in the friction groove, and a spring connected between the grinding block and the annular groove plate. The output end of the motor is connected to the annular groove plate.

[0012] As a preferred embodiment of the present invention: the welding assembly includes a bracket three connected to the frame base, a telescopic rod two installed on the bracket three, a connecting frame connected to the movable end of the telescopic rod two, a fixing part connected to the connecting frame, and a chuck connected to the fixing part and clamping a flange, wherein the chuck is connected to a touch sensor.

[0013] At the same time, the welding assembly also includes a rotating plate rotatably connected to the fixed part, a gear ring connected to the rotating plate, a second motor arranged on the fixed part, a rotating gear connected to the output end of the second motor and meshing with the gear ring, a support plate connected to the rotating plate, a welding head rotating on the support plate, and a rotating motor driving the welding head to rotate. When the flange is butt-jointed with the pipe fitting, the welding end of the welding head extends to the edge of the inner ring of the flange.

[0014] As a more optimal solution of the present invention: the bracket three is connected to the telescopic rod three and the Hall sensor, the movable end of the telescopic rod three is connected to a V-shaped correction plate, the correction plate corresponds to the position of the limit ring, and the bracket two is connected to a magnetic block corresponding to the Hall sensor.

[0015] The bracket three is provided with a touch switch component, and the touch end of the touch switch component is in active contact with the end of the pipe component.

[0016] The beneficial effects of the present invention are: The present invention performs welding operation on the connection between the pipe fitting and the flange by arranging a welding assembly, so that when the flange is welded to the pipe fitting, there will be no position deviation between the two. Under the action of the welding assembly, the connection between the flange and the pipe fitting can be welded in a circle without rotating the flange or the pipe fitting. Therefore, there will be no angular deviation between the two due to the rotation of the gap, which is more conducive to the welding operation of the flange and the pipe fitting, avoids the situation that the rotation angle of the pipe fitting and the rotation angle of the punch are not synchronized, and also avoids the situation that the welding head repeatedly welds the connection between the flange and the pipe fitting.

[0017] By setting up a grinding component, the tapered end of the pipe to be welded is deburred, so that when the flange is welded to the pipe, there will be no loose welding due to the burrs on the pipe wall, and the inner ring of the flange is in close contact with the side wall of the pipe, which improves the welding effect.

[0018] By setting the gear ring, gear and motor, the welding head can be driven to move around the connection between the flange and the pipe fitting, and the flange and the pipe fitting are in a stable and immobile state at this time. The welding head can be used to perform welding operations on the connection between the flange and the pipe fitting. Secondly, by setting a rotating motor, the welding head can be easily pulled out, which facilitates the continuous operation of the welding machine assembly.

[0019] By setting up the correction plate, when the work station plate moves to the bottom of the welding assembly, the telescopic rod three is started under the action of the Hall sensor and the magnetic block, thereby driving the correction plate close to the limit ring. When the limit ring and the correction plate come into contact, the position of the work station plate can be fine-tuned, so that the flange and the pipe fitting can be docked more accurately.

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example 1

[0031] An automated production device for an ETC gantry, such as Figure 1 - Figure 8 As shown, it includes a frame base 1, a rotating frame 2 rotating on the frame base 1, a grinding assembly 4 located above one of the station mechanisms 3, and a welding assembly 5 located above the other station mechanism 3. Specifically, at least two station mechanisms 3 for vertically restraining the pipe fittings are equidistantly arranged around the rotating frame 2; the grinding assembly 4 is used to rub the edge of the tapered end of the pipe fitting and remove the burrs on the pipe fitting; the welding assembly 5 is used to weld the flange to the tapered end of the pipe fitting.

[0032] In order to solve the problem of rotating frame 2 rotation; Figure 1 As shown, a bracket 6 is connected to one side of the frame base 1, a rotating shaft 7 is rotatably connected between the bracket 6 and the frame base 1, the rotating frame 2 is connected to the rotating shaft 7, a driving motor 8 is installed on the bracket 6, and the output end of the driving motor 8 is connected to one end of the rotating shaft 7. Driven by the driving motor 8, the rotating shaft 7 drives the rotating frame 2 to rotate, and then drives the station mechanism 3 connected to the rotating frame 2 to move synchronously.

[0033] In order to solve the stability problem when placing pipe fittings; Figure 6 As shown, the work station mechanism 3 includes a connecting rod 301 extending radially along the rotating frame 2, a work station plate 302 located on the end of the connecting rod 301 away from the rotating frame 2, and a member arranged on the work station plate 302 and used to clamp the pipe fitting. The bottom of the work station plate 302 is connected to a load-bearing plate 303 that supports the bottom of the pipe fitting. A sliding track 9 is fixedly connected to the frame base 1, and the load-bearing plate 303 is slidably connected to the sliding track 9. A limiting ring 10 consistent with the diameter of the pipe fitting is bolted to the side of the load-bearing plate 303 facing the pipe fitting, so that the user can place the pipe fitting accurately.

[0034] The clamping member is composed of a clamping cylinder 304 installed on the work station plate 302 and an arc-shaped clamping plate 305 connected to the movable end of the clamping cylinder 304. At least two clamping cylinders 304 are arranged on the work station plate 302, which can clamp the pipe fittings on the work station plate 302 more stably.

[0035] In order to solve the problem that there are burrs on the ends of pipe fittings, which is not conducive to welding operations; Figure 2 as well as Figure 7 As shown, the grinding assembly 4 includes a bracket 2 401 connected to the frame base 1, a telescopic rod 1 402 installed on the bracket 2 401, a lifting frame 403 connected to the movable end of the telescopic rod 1 402, a grinding piece rotatably connected to one end of the lifting frame 403 and used for grinding the pipe wall at the end of the pipe fitting, and a motor 1 404 for driving the grinding piece to operate.

[0036] Next, the grinding piece includes an annular groove plate 11 with a friction groove 12 facing the pipe fitting, a grinding block 13 arranged in the friction groove 12, and a spring 14 connected between the grinding block 13 and the annular groove plate 11. The output end of the motor 404 is connected to the annular groove plate 11. When the grinding block 13 is arranged in the friction groove 12, two rows are arranged along the circular arc of the friction groove 12. Therefore, the inner and outer sides of the pipe wall of the pipe fitting can be clamped just right, thereby increasing the deburring effect on the pipe wall of the pipe fitting.

[0037] In order to solve the problem of efficient welding at the joints between flanges and pipe fittings; Figure 1 as well as Figure 8 As shown, the welding assembly 5 includes a bracket 3 15 connected to the frame base 1, a telescopic rod 2 501 installed on the bracket 3 15, a connecting frame 502 connected to the movable end of the telescopic rod 2 501, a fixing member 503 connected to the connecting frame 502, and a chuck 504 connected to the fixing member 503 and clamping a flange, and a touch sensor 16 is connected to the chuck 504. The chuck 504 is a pneumatic chuck 504 and is a prior art structure. It is widely used in the industrial field and will not be elaborated in detail. In the present invention, it is mainly used to clamp the flange at a fixed position, and then, driven by the telescopic rod 2 501, the flange is sleeved on the tapered end of the pipe fitting. After the welding is completed, the flange is released under the control of the system, and then the next flange placed on the chuck 504 is clamped, and the cycle is repeated.

[0038] The welding assembly 5 also includes a rotating plate 17 rotatably connected to the fixing member 503, a gear ring 18 connected to the rotating plate 17, a motor 19 arranged on the fixing member 503, a rotating gear 20 connected to the output end of the motor 19 and meshing with the gear ring 18, a support plate 21 connected to the rotating plate 17, a welding head 22 rotating on the support plate 21, and a rotating motor 23 driving the welding head 22 to rotate. When the flange and the pipe fitting are welded, the welding end of the welding head 22 extends to the edge of the inner ring of the flange. When the welding operation between the flange and the pipe fitting is completed, the welding head 22 is rotated so that it is no longer located under the flange, so as to facilitate the removal of the welding head 22 from under the welded flange.

[0039] When this embodiment is in use, the pipe fitting is first placed vertically on the work station mechanism 3 provided with the grinding assembly 4, and the pipe fitting is clamped by the clamping cylinder 304. At this time, the conical end of the pipe fitting is located at the top, and the other end of the pipe fitting is constrained in the limit ring 10, so that the pipe fitting is stabilized on the work station plate 302, and then the telescopic rod 402 is started to drive the lifting frame 403 to move downward, and then drive the grinding piece to move downward. When the friction groove 12 on the annular groove plate 11 covers the end wall of the pipe fitting, the grinding block 13 at this time will also correspondingly conflict with the pipe wall, and then the motor 404 is started, and the motor 404 will drive the annular groove plate 11 to rotate on the lifting frame 403, so that friction is generated between the grinding block 13 and the pipe wall, and finally the burrs on the pipe wall are removed to prepare for the subsequent welding operation.

[0040] Then, the rotating frame 2 is rotated to move the workstation to the position directly below the welding assembly 5, and then the telescopic rod 2 501 is started to drive the fixing part 503 to move downward. When the flange clamped on the chuck 504 is placed on the appropriate position of the pipe fitting, the fixing part 503 is moved. Under the action of the motor 2 19, the gear 20 drives the gear ring 18 to rotate. When the rotating plate 17 rotates, it will drive the welding head 22 to rotate synchronously. At the same time, the welding head 22 is started and the welding operation is performed. When the welding head 22 goes around the pipe fitting, the welding head 22 will The connection between the flange and the pipe fitting is welded. After the welding head 22 goes around the pipe fitting once, under the control of the background system, the telescopic rod 2 501 is started to move the fixing and chuck 504 upward. At the same time, under the action of the rotating motor 23, the welding head 22 is offset so that the welding head 22 can be smoothly moved out from under the flange. At this time, the welding operation of the flange and the pipe fitting is completed. In this process, there is no need to rotate the flange or the pipe fitting, so there will be no angle deviation between the two due to the rotation of the gap, which is more conducive to the welding operation of the flange and the pipe fitting. Example 2

[0041] An automated production device for an ETC gantry, such as Figure 2 as well as Figure 4 As shown, in order to solve the problem of automatic operation between the welding assembly 5 and the pipe fitting, and the longitudinal relative problem between the pipe fitting and the flange; this embodiment makes the following improvements on the basis of embodiment 1: a telescopic rod three 24 and a Hall sensor 25 are connected to the bracket three 15, a V-shaped correction plate 26 is connected to the movable end of the telescopic rod three 24, and the correction plate 26 corresponds to the position of the limit ring 10, a magnetic block 27 corresponding to the Hall sensor 25 is connected to the bracket two 401, and a touch switch 28 is provided on the bracket three 15, and the touch end of the touch switch 28 is in active contact with the end of the pipe fitting.

[0042] When the present embodiment is in use, when the pipe fitting moves with the work station plate 302 to the bottom of the welding assembly 5, the Hall sensor 25 senses the magnetic block 27 and transmits a signal to the operating system, which is a programmable logic controller and a common operating system in the field of industrial equipment. Under the control of the operating system, the telescopic rod three 24 is started, thereby driving the correction plate 26 to approach the limit ring 10. When the limit ring 10 conflicts with the correction plate 26, the position of the work station plate 302 can be fine-tuned to make the flange and the pipe fitting more accurate when docking. After the welding is completed, when the telescopic rod two 501 drives the fixing part 503 to move upward, it will touch the touch switch part, and then the telescopic rod three 24 will be started to move the correction plate 26 to the initial position. Then, under the action of the drive motor 8, the work station plate 302 is moved, and the flange and pipe fitting after welding are moved to the appropriate position and removed. At this time, the next pipe fitting to be welded will move to the position of the welding assembly 5.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
