Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a pipe fitting press-riveting device for metal boxes. Background Technology

[0002] In the industrial manufacturing sector, metal enclosures serve as crucial structures for supporting, protecting, or integrating various components. The quality of their connection with pipe fittings directly impacts the overall equipment's performance, safety, and lifespan. The connection between pipe fittings and metal enclosures must meet core requirements such as structural stability and reliable sealing. Riveting, with its advantages of high connection strength, smooth workpiece surface after operation, and minimal deformation, has become a widely adopted connection method in this field.

[0003] In an existing metal box-type pipe fitting crimping device, the bonding of the connecting pipe to the metal box typically requires manual pre-application of adhesive on the surface of the connecting pipe, manual positioning of the adhesive-coated connecting pipe to the insertion hole on the metal box, and finally manual operation of the crimping device to crimp the connecting pipe. The entire process requires manual operation, significantly reducing production efficiency and warranting improvement. Summary of the Invention

[0004] To improve production efficiency, this invention provides a pipe fitting pressing and riveting device for metal boxes.

[0005] The present invention provides a pipe fitting pressing and riveting device for metal boxes, which adopts the following technical solution: A pipe fitting press-fitting device for a metal box includes a workbench and a fixing mechanism for fixing the metal box to the workbench, a press-fitting device installed on the workbench for clamping and press-fitting a connecting pipe into the metal box, and a spraying device for applying adhesive to the connecting pipe during the press-fitting process of the connecting pipe into the metal box. The riveting device includes a clamping mechanism for clamping the connecting pipe and a driving mechanism for moving the clamping mechanism on the worktable to insert the connecting pipe into the metal housing.

[0006] By adopting the above technical solution, the metal box is placed on the workbench and fixed by a fixing mechanism. Then, the connecting pipe is manually placed into the clamping mechanism of the riveting device to clamp it, ensuring stability during subsequent movement and rotation. The drive mechanism converts power into horizontal displacement of the clamping mechanism, pushing the connecting pipe towards the preset hole in the metal box to achieve riveting. Simultaneously, the spraying device sprays the surface of the connecting pipe while it is moving, allowing gluing and riveting to be performed together. The entire process only requires manual placement of the connecting pipe into the riveting device and fixing it by the clamping mechanism, thus improving production efficiency.

[0007] Optionally, the drive mechanism includes a first bidirectional screw rotatably mounted on the worktable, a first motor that drives the first bidirectional screw to rotate, and a drive block threadedly connected to the first bidirectional screw. The clamping mechanism includes a clamping disk connected to the drive block, a clamping plate movably installed in the inner cavity of the clamping disk, and a clamping motor that drives the clamping plate to clamp the connecting pipe; the clamping disk has a clamping hole in the middle for inserting the connecting pipe, and the clamping plates are circumferentially distributed in the clamping hole to press and clamp the connecting pipe from the circumferential direction. The first motor drives the clamping plate to move horizontally on the worktable to press and rivet the connecting pipe clamped on the clamping plate into the metal housing.

[0008] By adopting the above technical solution, when the connecting tube is inserted into the clamping hole in the middle of the clamping plate, the clamping motor starts and drives the circumferentially distributed clamping plates to move synchronously. The clamping plates apply pressure from multiple directions around the connecting tube, firmly clamping the connecting tube on the clamping plate. Then, the first motor is started, driving the first bidirectional screw to rotate. Since the drive block is threadedly connected to the first bidirectional screw, the rotational motion of the screw is converted into the horizontal linear motion of the drive block. The clamping plate connected to the drive block moves horizontally with the drive block and is adjusted to be aligned with the position to be riveted on the metal box. The first motor continues to drive the clamping plate to move towards the metal box. Using the horizontal thrust of the clamping plate, the clamped connecting tube is pressed into the preset mounting hole of the metal box. By continuously applying pressure, the riveting and fixing of the connecting tube and the metal box is completed.

[0009] Optionally, a transmission mechanism for driving the clamping disk to rotate is provided between the clamping disk and the driving block; the transmission mechanism includes a transmission shaft rotatably connected to the top of the driving block, a gear and rack assembly that drives the transmission shaft to rotate during the horizontal movement of the clamping disk, a rotating disk connected to the clamping disk, and a first helical gear assembly connecting the transmission shaft and the rotating disk. The gear and rack assembly includes a drive rack fixedly mounted on the worktable and a drive gear fixedly connected to the transmission shaft. The drive rack and the drive gear mesh to rotate the transmission shaft when the drive block moves horizontally.

[0010] By adopting the above technical solution, when the first motor drives the drive block to move horizontally, the drive gear on the transmission shaft moves relative to the drive rack fixed on the worktable. Since the drive rack is fixed, the meshing action of the gear and rack converts the horizontal displacement of the drive block into the rotational motion of the transmission shaft. The rotation of the transmission shaft changes the transmission direction through the first helical gear assembly, and the power is transmitted from the horizontal transmission shaft to the vertical rotating disk, which ultimately drives the entire clamping disk to rotate synchronously. This allows the clamping disk and the connecting pipe to rotate synchronously through the transmission mechanism while moving horizontally. Therefore, when the spraying device applies glue to the connecting pipe, the application is more uniform. At the same time, the riveting process of the connecting pipe changes from a simple axial pressing to a compound action of "pressing + rotation", resulting in a better riveting effect.

[0011] Optionally, the clamping mechanism further includes an arc-shaped rod, a connecting rod, and a reversing rod; the connecting rod is radially slidably mounted on the rotating disk; both ends of the arc-shaped rod are rotatably connected to the connecting rod and the clamping disk, respectively; the reversing rod is rotatably connected to the clamping disk, and both ends of the reversing rod are rotatably connected to the connecting rod and the clamping plate, respectively. When the clamping motor drives the clamping disk to rotate, the clamping disk drives the arc-shaped rod to rotate and drives the connecting rod and the clamping plate to move in opposite directions through the reversing rod to achieve clamping and releasing.

[0012] By adopting the above technical solution, when the clamping motor drives the clamping disk to rotate, the rotation of the clamping disk directly drives the arc-shaped rod and the reversing rod connected to it to rotate synchronously, which in turn drives the connecting rod and the clamping plate to move. At the same time, the reversing rod, as an intermediate transmission component, connects the connecting rod and the clamping plate at its two ends respectively, converting the radial movement of the connecting rod into the opposite or opposite movement of the clamping plate. Therefore, when the connecting rod slides outward, the clamping plate contracts inward to clamp the connecting tube, and when the connecting rod slides inward, the clamping plate opens outward and no longer clamps the connecting tube.

[0013] Optionally, the clamping plate includes a front plate and a rear plate that are connected and cooperate with each other, and a mounting chamber is formed between the front plate and the rear plate. The arc-shaped rod, the reversing rod and the clamping plate are all movably disposed in the mounting chamber. The clamping disc has a through-hole with fan-shaped holes distributed circumferentially, and the fan-shaped holes have an inclined surface inside. The workbench is equipped with an H-shaped protective frame, which has a sliding adhesive spraying channel for the clamping mechanism to slide through. The end of the sliding adhesive spraying channel has a collection groove for collecting excess adhesive. The clamping mechanism also includes a protective box, and the drive shaft and the first helical gear assembly are both located inside the protective box.

[0014] By adopting the above technical solution, when the clamping plate and the connecting pipe move along the sliding adhesive spraying channel, the spraying device can simultaneously complete the adhesive spraying operation on the connecting pipe. At the same time, the fan-shaped hole, the inclined surface, and the sliding adhesive spraying channel lock the clamping plate and the connecting pipe to generate wind force when they rotate, which can blow excess adhesive into the collection tank for collection. Meanwhile, during the riveting process, the H-shaped protective frame and the protective box form multiple safety barriers to protect the operators and equipment parts.

[0015] The spraying device includes a storage tank disposed above the workbench for storing adhesive, a nozzle for spraying adhesive onto a connecting pipe, and a first pump connecting the storage tank and the nozzle to deliver adhesive into the nozzle; the storage tank is provided with a stirring and scraping mechanism for stirring the adhesive and scraping the adhesive off the inner wall of the storage tank.

[0016] By adopting the above technical solution, the working sequence of the spraying device is coordinated with the movement and rotation of the clamping mechanism to form a continuous process flow of "clamping → spraying → riveting". When the clamping mechanism moves the connecting pipe to the spraying station, the first pump acts as a power source to pressurize and deliver the glue in the storage tank to the nozzle through the connecting pipe. The nozzle sprays the glue evenly on the surface of the connecting pipe in the form of mist or line. At the same time, the stirring and scraping mechanism stirs the glue in the storage tank to prevent the glue from settling, separating or solidifying due to long-term standing, ensuring uniform glue concentration and consistent spraying effect. It can also remove the glue adhering to the inner wall of the storage tank in time, avoiding glue drying and accumulating on the tank wall and reducing material waste.

[0017] The stirring and scraping mechanism includes a stirring shaft rotatably installed inside the storage tank, a third motor that drives the stirring shaft to rotate, a stirring blade fixedly installed on the outside of the stirring shaft for stirring the glue, and a scraping frame rotatably installed on the outside of the stirring shaft for scraping the glue off the inner wall of the storage tank. The stirring shaft is equipped with a second helical gear assembly that drives the stirring blades and the scraper to rotate in opposite directions.

[0018] By adopting the above technical solution, the third motor provides the initial driving force, which drives the stirring shaft to rotate. The second helical gear assembly on the stirring shaft decomposes the single rotational power into two opposing rotational motions. One set of power is transmitted to the stirring blades, and the other set of power is transmitted to the scraper, causing the two to rotate in opposite directions. During the rotation, the stirring blades cut and mix the glue in the storage tank, breaking up any sedimentation or stratification that may form, ensuring uniform glue concentration and viscosity. At the same time, because the edge of the scraper is in close contact with the inner wall of the storage tank, the scraper can completely scrape off the glue adhering to the tank wall when it rotates.

[0019] The bottom of the workbench is provided with a collection mechanism for recycling adhesive; the collection mechanism includes a collection box communicating with the collection tank and a second pump connected to the outlet of the collection box for conveying the adhesive in the collection box back to the spraying device.

[0020] By adopting the above technical solution, excess glue during the spraying process flows through the sliding glue spraying channel of the H-shaped protective frame and eventually collects in the collection tank at the end of the channel. The collection tank, as a primary collection device, guides the glue to the collection box connected to it, completing the transfer of glue from the work area to the storage space and preventing glue from dripping and contaminating the workbench or the ground. The collection box, as a temporary storage container for recycled glue, centrally stores the glue flowing in from the collection tank. The second pump, as a power source, pressurizes and extracts the recycled glue temporarily stored in the collection box and transports it back to the storage tank of the spraying device through connecting pipelines, realizing the recycling of glue.

[0021] The collection box is fitted with a filter screen for filtering the recycled glue, and the filter screen is fixed to the collection box by a locking component. The locking assembly includes a pressure plate slidably mounted on the collection box, a locking rod fixedly mounted on the pressure plate and interlocking with the filter plate to lock the filter plate to the collection box, and a compression spring that drives the locking rod to always have a tendency to insert into the filter plate.

[0022] By adopting the above technical solution, the recycled glue flowing into the collection box from the collection tank first undergoes filtration by a filter screen. The mesh structure of the filter screen can intercept solid impurities in the glue, preventing impurities from clogging the nozzle or affecting the coating quality as they circulate back to the spraying device. Simultaneously, the filtered clean glue is stored at the bottom of the collection box, providing a basic guarantee for subsequent recycling. Secondly, the compression spring, as an elastic driving element, constantly applies elastic thrust to the pressure plate, keeping the locking rod fixed to the pressure plate inserted into the corresponding locking hole of the filter screen. The locking rod and the filter screen are interlocked... The filter screen is firmly fixed in the preset installation position of the collection box to prevent it from shifting or falling off due to glue impact or equipment vibration. When it is necessary to clean or replace the filter screen, the operator only needs to overcome the elastic force of the pressure spring to pull the pressure plate, so that the locking rod can be pulled out from the lock hole of the filter screen and the locking state can be released. At this time, the filter screen can be easily pulled out of the collection box for cleaning of impurities or replacement with a new filter screen. During installation, simply insert the filter screen into the slot of the collection box, release the pressure plate, and the pressure spring will automatically push the locking rod back into the lock hole to complete the fixing.

[0023] Optionally, the fixing mechanism includes a second bidirectional screw rotatably mounted on the worktable, a clamping block threadedly connected to the second bidirectional screw, and a second motor for driving the second bidirectional screw to rotate; the second bidirectional screw is symmetrically arranged on the worktable, and a synchronous belt assembly for driving the two to rotate synchronously is connected between the two sides of the second bidirectional screw; the second motor drives the second bidirectional screw to rotate so as to drive the clamping block to clamp it from all sides of the metal housing.

[0024] By adopting the above technical solution, the second motor provides driving force to drive one of the second bidirectional screws to rotate. The power is transmitted to the other symmetrically distributed second bidirectional screws through the synchronous belt assembly, so that the two second bidirectional screws achieve completely synchronous rotational motion. When the two second bidirectional screws rotate, the clamping block threaded to them will move synchronously towards the center along the axis of the second bidirectional screw, applying clamping force from all sides of the metal housing and fixing it firmly in the preset position of the worktable.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. After the metal box is placed on the workbench, it can be fixed by the fixing mechanism. Then, the connecting pipe is manually placed into the clamping mechanism of the riveting device to clamp the connecting pipe, so that the connecting pipe remains stable during subsequent movement and rotation. The drive mechanism converts the power into the horizontal displacement of the clamping mechanism, pushing the connecting pipe to the preset hole position of the metal box to achieve riveting. At the same time as the connection is moving, the spraying device sprays the surface of the connecting pipe, so that the gluing and riveting can be carried out at the same time. The whole process only requires the manual placement of the connecting pipe into the riveting device and fixing it by the clamping mechanism, thus improving production efficiency. 2. When the first motor drives the drive block to move horizontally, the drive gear on the transmission shaft moves relative to the drive rack fixed on the worktable. Since the drive rack is fixed, the meshing action of the gear and rack converts the horizontal displacement of the drive block into the rotational motion of the transmission shaft. The rotation of the transmission shaft changes the transmission direction through the first helical gear assembly. The power is transmitted from the horizontal transmission shaft to the vertical rotating disk, and finally drives the entire clamping disk to rotate synchronously. This allows the clamping disk and the connecting pipe to rotate synchronously through the transmission mechanism while moving horizontally. Therefore, when the spraying device applies glue to the connecting pipe, the application is more uniform. At the same time, the riveting process of the connecting pipe changes from a simple axial pressing to a compound action of "pressing + rotation", resulting in a better riveting effect. 3. The working sequence of the spraying device is coordinated with the movement and rotation of the clamping mechanism to form a continuous process flow of "clamping → spraying → riveting". When the clamping mechanism moves the connecting pipe to the spraying station, the first pump acts as a power source to pressurize and deliver the glue in the storage tank to the nozzle through the connecting pipe. The nozzle sprays the glue evenly on the surface of the connecting pipe in the form of mist or line. At the same time, the stirring and scraping mechanism stirs the glue in the storage tank to prevent the glue from settling, separating or solidifying due to long-term standing, ensuring uniform glue concentration and consistent spraying effect. It can also remove the glue adhering to the inner wall of the storage tank in time to avoid the glue drying and accumulating on the tank wall and reduce material waste. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This invention discloses a pipe fitting pressing and riveting device for metal boxes.

[0030] Reference Figure 1 and Figure 2 A pipe fitting riveting device for a metal box includes a worktable 1, a fixing mechanism 2, a riveting device 3, a spraying device 5, and a collection device 6. The fixing mechanism 2 is used to fix the metal box. The riveting device 3 is used to fix the connecting pipe, causing it to move and rotate while simultaneously riveting it into the metal box. The spraying device 5 is used to spray adhesive onto the rotating connecting pipe during movement. The collection device 6 is used to recover excess adhesive generated during the spraying of the connecting pipe.

[0031] The riveting device 3 includes a clamping mechanism 32 for clamping the connecting pipe and a driving mechanism 31 for moving the clamping mechanism 32 on the worktable 1 to insert the connecting pipe into the metal box.

[0032] During processing, the metal box is first placed on the workbench 1, and then fixed by the fixing mechanism 2 to prevent the metal box from moving when the connecting pipe is riveted in. Then, the connecting pipe is manually installed into the clamping mechanism 32, and then the driving mechanism 31 drives the clamped connecting pipe to rotate and rivet into the metal box while moving. At the same time as the connecting pipe moves and is riveted into the metal box, the spraying device 5 sprays glue onto the surface of the connecting pipe. The whole process only requires manual insertion of the connecting pipe into the riveting device 3, thus improving work efficiency.

[0033] Reference Figure 2 The fixing mechanism 2 includes a second bidirectional screw 21, a clamping block 22, a second motor 23, and a synchronous belt assembly 26. There are two second bidirectional screws 21, symmetrically arranged on the worktable 1, and both second bidirectional screws 21 are rotatably mounted inside the worktable 1. The outer side of each second bidirectional screw 21 has two external threads with opposite directions of rotation. One of the second bidirectional screws 21 is connected to the second motor 23 via a coupling, and the two second bidirectional screws 21 are connected by the synchronous belt assembly 26, so that when the second motor 23 drives one of the second bidirectional screws 21 to rotate, the other second bidirectional screw 21 rotates synchronously.

[0034] Each second bidirectional screw 21 has two clamping blocks 22 threadedly mounted on it, and the two clamping blocks 22 are located on different external threads. A T-shaped moving block 24 is fixedly connected to the bottom of the clamping block 22. A T-shaped moving groove 25 matching the T-shaped moving block 24 is opened on the top of the worktable 1. The T-shaped moving block 24 is slidably installed in the corresponding T-shaped moving groove 25. The cooperation between the T-shaped moving block 24 and the T-shaped moving groove 25 causes the clamping block 22 to only produce horizontal displacement.

[0035] In this embodiment, the timing belt assembly 26 includes two timing pulleys 261 and a timing belt 262. The two timing pulleys 261 are fixedly sleeved on the outside of the corresponding second bidirectional screw 21, and the timing belt 262 is sleeved on the outside of the two timing pulleys 261.

[0036] When the second motor 23 drives the second bidirectional screw 21 to rotate, the clamping block 22 is threadedly connected to the second bidirectional screw 21, and the T-shaped moving block 24 and the T-shaped moving groove 25 provide horizontal guidance for the clamping block 22. The clamping block 22 will move horizontally along the axial direction of the second bidirectional screw 21, driving the clamping block 22 to move closer to the metal box and clamping the metal box around its perimeter, thus preventing the metal box from moving when the connecting pipe is riveted into the metal box.

[0037] Reference Figure 1 and Figure 3 The drive mechanism 31 includes a first bidirectional screw 311, drive blocks 312, and a first motor 313. The first bidirectional screw 311 is rotatably mounted on the bottom of the worktable 1, and the first motor 313 drives the first bidirectional screw 311 to rotate. The first bidirectional screw 311 has two external threads with opposite directions of rotation on its outer side. There are two drive blocks 312, which are threadedly connected to the corresponding external threads of the first bidirectional screw 311. The worktable 1 has two sliding holes through which the two drive blocks 312 pass for positioning. Each drive block 312 is equipped with a clamping mechanism 32, thereby simultaneously riveting the connecting pipe from both sides of the metal housing on the worktable 1.

[0038] When the first motor 313 drives the first bidirectional screw 311 to rotate, the drive block 312 can move along the first bidirectional screw 311, thereby driving the clamping mechanism 32 to approach the metal box through the drive block 312, so as to press and rivet the connecting pipe into the metal box.

[0039] In this embodiment, an H-shaped protective frame 11 is fixedly installed on the workbench 1. The H-shaped protective frame 11 has an H-shaped cross-section and a sliding glue spraying channel 114 at its top, which faces the metal box. The end of the sliding glue spraying channel 114 near the metal box has a collection groove 115 for recycling glue. The inner bottom surface of the sliding glue spraying channel 114 has a waist-shaped hole 111 extending through it along its length, and grooves 112 are formed on both sides of the waist-shaped hole 111.

[0040] Reference Figure 3 and Figure 4 The clamping mechanism 32 includes a clamping disk 321, a clamping plate 322, an arc-shaped rod 323, a connecting rod 324, a reversing rod 325, a clamping motor 326, and a transmission mechanism 4. The transmission mechanism 4 is used to drive the connecting tube to rotate synchronously during the horizontal insertion of the metal box. The transmission mechanism 4 includes a transmission shaft 41, a gear and rack assembly 42, a first helical gear assembly 43, and a rotating disk 46.

[0041] The drive shaft 41 is rotatably mounted on the drive block 312 and passes through the oblong hole 111. The drive shaft 41 can move within the oblong hole 111 as the drive block 312 moves. The gear and rack assembly 42 includes a drive gear 421 and a drive rack 422. The drive gear 421 is fixedly mounted on the drive shaft 41, and the drive rack 422 is fixedly mounted on the H-shaped protective frame 11. The drive gear 421 meshes with the drive rack 422. When the drive shaft 41 moves horizontally within the oblong hole 111, the drive gear 421 can roll on the drive rack 422, thereby driving the drive shaft 41 to rotate.

[0042] The rotating disk 46 is connected to the transmission shaft 41 via a first helical gear assembly 43. The first helical gear assembly 43 includes a first bevel gear 431 and a second bevel gear 432. The first bevel gear 431 is fixedly mounted on the transmission shaft 41, and the first bevel gear 431 and the second bevel gear 432 mesh with each other at a 90° angle. A rotating shaft 44 is fixedly mounted inside the second bevel gear 432, and the rotating shaft 44 is fixedly connected to the rotating disk 46. When the transmission shaft 41 rotates, the rotating disk 46 can rotate synchronously.

[0043] To protect the transmission mechanism 4, an H-shaped protective frame 11 has a protective box 45 slidably mounted within the sliding adhesive spraying channel 114. The bottom of the protective box 45 has a slider 113 that slides and engages with the sliding groove 112. The gear and rack assembly 42 is located below the H-shaped protective frame 11. The transmission shaft 41 and the first helical gear assembly 43 are both located within the protective box 45. The rotating disk 46 is rotatably connected to the outer wall of the protective box 45. When the transmission shaft 41 moves horizontally, the protective box 45 can move synchronously with the rotating disk 46 within the sliding adhesive spraying channel 114, and the rotating disk 46 can also rotate synchronously.

[0044] A clamping motor 326 is fixedly mounted on a rotating disk 46, and a clamping disk 321 is fixedly connected to the output shaft of the clamping motor 326. The clamping disk 321 includes a front disk 3212 and a rear disk 3211 that are interconnected and cooperate with each other, forming a mounting chamber 3213 between them. The clamping disk 321 has through-holes 3215 for weight reduction, the through-holes 3215 being circumferentially distributed and having inclined surfaces 3216 within them. The through-holes 3215 avoid the mounting chamber 3213. A clamping hole 327 for inserting a connecting pipe is provided in the center of the front disk 3212, extending into the mounting chamber 3213.

[0045] The arc-shaped rod 323, the reversing rod 325, the connecting rod 324, and the clamping plate 322 are evenly distributed circumferentially on the clamping plate 321. The arc-shaped rod 323, the reversing rod 325, and the clamping plate 322 are all located within the mounting chamber 3213. The clamping plate 322 is circumferentially distributed around the clamping hole 327 to clamp the connecting pipe circumferentially. The connecting rod 324 is radially slidably mounted on the surface of the rotating plate 46 and passes through the rear plate 3211 into the mounting chamber 3213. The rear plate 3211 has a clearance hole 3214 for the connecting rod 324 to enter and move. The two ends of the arc-shaped rod 323 are rotatably connected to the connecting rod 324 and the rear plate 3211, respectively. The reversing rod 325 is rotatably mounted within the mounting chamber 3213, and its two ends are rotatably connected to the connecting rod 324 and the clamping plate 322, respectively.

[0046] When the clamping motor 326 drives the clamping disk 321 to rotate, the connecting rod 324 is limited to circumferential rotation by the rotating disk 46. Therefore, the clamping disk 321 can drive the connecting rod 324 to move radially on the rotating disk 46 by rotating the arc rod 323. The clamping plate 322 can move in the opposite direction to the connecting rod 324 by rotating the reversing rod 325, thereby clamping and releasing the connecting tube when the clamping motor 326 is running.

[0047] Since the clamping plate 321 and the rotating plate 46 are connected by a connecting rod 324, when the rotating plate 46 rotates, the connecting pipe and the clamping plate 321 can rotate synchronously. Furthermore, when the rotating plate 46 rotates, the connecting rod 324 has an outward centrifugal force, while the clamping plate 322 moves in the opposite direction to the connecting rod 324, allowing the clamping plate 322 to clamp the connecting pipe more tightly.

[0048] When it is necessary to fix the connecting pipe, first insert the connecting pipe into the clamping hole 327, and then start the clamping motor 326 to drive the clamping plate 321 to rotate so that the connecting pipe is clamped by the clamping plate 322. Start the first motor 313 to drive the clamping plate 321 to move the connecting pipe horizontally and rotate during the movement. With the above structure, the spraying device 5 can spray the surface of the connecting pipe more evenly during the riveting process into the metal box, and at the same time, the riveting process of the connecting pipe is changed from a simple axial pressing into a "pressing + rotation" compound action, resulting in a better riveting effect.

[0049] Furthermore, when the clamping disc 321 rotates, it generates wind through the fan-shaped hole 3215 and the inclined surface 3216. The wind can blow excess glue in the sliding glue spraying channel 114 to the collection tank 115.

[0050] Furthermore, a T-shaped slider 328 is fixedly installed at the end of the connecting rod 324, and a T-shaped groove 329 matching the T-shaped slider 328 is provided on the rotating disk 46, and the T-shaped slider 328 is slidably installed in the T-shaped groove 329.

[0051] Reference Figure 1 , Figure 5 and Figure 6 The spraying device 5 includes a storage tank 51, a nozzle 52, a first pump 53, and a stirring and scraping mechanism 55. A support frame 54 is fixedly installed on the top of the workbench 1. The top of the storage tank 51 is connected to a feed pipe 511, and a sealing plug 512 is inserted into the feed pipe 511. The storage tank 51 and the first pump 53 are both fixedly installed on the top of the support frame 54. The first pump 53 connects the storage tank 51 and the nozzle 52. The nozzle 52 points towards the sliding adhesive spraying channel 114 and is directly opposite the connecting pipe. The stirring and scraping mechanism 55 is located inside the storage tank 51 and is used to stir the adhesive and scrape off residual adhesive from the inner wall of the tank.

[0052] The stirring and scraping mechanism 55 includes a stirring shaft 551, a third motor 552, stirring blades 553, a scraping frame 554, and a second helical gear assembly 556. A protective box 555 is fixedly installed on the top of the storage tank 51. The third motor 552 and the second helical gear assembly 556 are located inside the protective box 555 to protect the third motor 552 and the second helical gear assembly 556.

[0053] The third motor 552 is fixedly connected to the stirring shaft 551, the stirring blade 553 is fixedly mounted on the stirring shaft 551, and the scraper 554 is sleeved and mounted on the outside of the stirring shaft 551. The stirring shaft 551 and the scraper 554 are connected by a second helical gear assembly 556 to drive the stirring blade 553 and the scraper 554 to rotate in opposite directions.

[0054] The second helical gear assembly 556 includes a third bevel gear 5561, a fourth bevel gear 5562, and a fifth bevel gear 5563. The third bevel gear 5561 meshes with the fourth bevel gear 5562, and the fourth bevel gear 5562 meshes with the fifth bevel gear 5563. The third bevel gear 5561 is fixedly mounted on the stirring shaft 551. A support shaft 5564 is fixedly mounted inside the fourth bevel gear 5562, and the support shaft 5564 is rotatably mounted on the inner wall of the protective housing 555. A rotating cylinder 5565 is fixedly mounted inside the fifth bevel gear 5563, and the rotating cylinder 5565 passes through the storage tank 51 and is fixedly connected to the scraper frame 554. The stirring blade 553, the stirring shaft 551, and the scraper frame 554 are all rotatably mounted inside the storage tank 51.

[0055] When spraying is required, the first pump 53 is started to extract the adhesive from the storage tank 51 and spray it evenly onto the surface of the connecting pipe through the nozzle 52. At the same time, the third motor 552 is started to drive the stirring shaft 551, stirring blades 553 and scraper 554 to start rotating, stirring the adhesive in the storage tank 51 to prevent the adhesive from settling, separating or solidifying due to prolonged standing, ensuring uniform adhesive concentration and consistent spraying effect. Meanwhile, the scraper 554 can promptly remove the adhesive adhering to the inner wall of the storage tank 51, preventing the adhesive from drying and accumulating on the tank wall and reducing material waste.

[0056] Reference Figure 1 , Figure 7 and Figure 8 A collection mechanism 6 is located at the bottom of the workbench 1. The collection mechanism 6 includes a collection box 61, a filter screen 65, and a second pump 62. A placement rack 63 is fixedly installed at the bottom of the workbench 1, and both the collection box 61 and the second pump 62 are fixedly installed on the placement rack 63. The collection box 61 is connected to the collection tank 115 through a collection pipe 64 to recover excess glue in the collection tank 115 to the collection box 61. The second pump 62 connects the collection box 61 and the storage tank 51 to transport the glue in the collection box 61 back to the storage tank 51.

[0057] A filter screen 65 is inserted into a collection box 61 and is used to filter the recycled glue. The filter screen 65 is inserted into the side wall of the collection box 61 and locked to the collection box 61 by a locking assembly 66.

[0058] The locking assembly 66 includes a pressure plate 661, a locking rod 662, and a compression spring 663. A sliding groove 664 is provided on one side of the collection box 61. The pressure plate 661 is slidably installed within the sliding groove 664. The locking rod 662 is fixedly installed on the top of the pressure plate 661, passing through the collection box 61 and engaging with the filter screen 65. The compression spring 663 is located between the pressure plate 661 and the sliding groove 664, and the compression spring 663 drives the locking rod 662 to always tend to insert into the filter screen 65.

[0059] When the recycled glue flows from the collection pipe 64 into the collection box 61, the filter plate 65 intercepts any impurities that may be present in the glue, ensuring that the glue entering the bottom of the collection box 61 remains clean, thus providing quality assurance for the subsequent recycling of the glue into the storage tank 51. After the filter plate 65 is movably inserted into the collection box 61, under the elastic force of the compression spring 663, the pressure plate 661 in the sliding groove 664 will drive the locking rod 662 to maintain a vertical upward trend, causing the locking rod 662 to insert into the filter plate 65 and the collection box 61, thereby firmly fixing the filter plate 65 in the collection box 61. When it is necessary to clean or replace the filter plate 65, simply pull down the pressure plate 661 to release the locking rod 662 from the filter plate 65 and the collection box 61, thereby releasing the locking state. At this time, the filter plate 65 can be easily pulled out of the collection box 61 for cleaning or replacement.
