Description

Technical Field

[0001] This application relates to the field of pin welding, and in particular to a fully automatic welding device for pin welding. Background Technology

[0002] A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. In practical applications, pins may also need to be welded to other products for ease of use.

[0003] Currently, in related technologies, Chinese patent CN217513165U discloses a welding device for manufacturing and processing pin shafts. This device includes a base with a groove on its top. A first motor is fixedly installed inside the groove, and a top plate is fixedly connected to the output end of the first motor. A rotating seat is fixedly installed on the top of the top plate, and a welding platform is rotatably mounted on the top of the rotating seat via a rotating shaft. A sliding groove is formed on the top of the welding platform, and a first threaded rod is rotatably installed inside the sliding groove. This welding device for manufacturing and processing pin shafts allows the top plate to rotate via the first motor, facilitating welding operations by rotating the pin shaft and the product without requiring the device to be rotated around the shaft.

[0004] However, during the welding process of the pin, some welding slag is easily generated and accumulates on the welding platform, which can easily affect the welding of the next product to the pin; but if the welding slag is directly cleaned onto the ground, it can easily cause a dirty and messy working environment. Summary of the Invention

[0005] In order to improve the problems existing in the above-mentioned technology in the pin welding process, this application provides a fully automatic welding device for pin welding.

[0006] This application provides a fully automatic welding device for pin welding, which adopts the following technical solution:

[0007] A fully automatic welding device for pin welding includes: a clamping table and a worktable. The clamping table is fixed above the worktable, and a clamping assembly for clamping the pin is provided at the bottom of the clamping table. A welding table is provided at the top of the worktable, and an adjustment assembly is provided between the welding table and the worktable. A processing mechanism is provided between the welding table and the worktable.

[0008] The processing mechanism includes a enclosure assembly and a lifting assembly. The enclosure assembly includes a enclosure plate, which is sleeved on the welding table. The enclosure plate has a collection cavity inside and an inlet groove communicating with the collection cavity is opened on the inner side wall of the enclosure plate. The lifting assembly is disposed between the enclosure plate and the worktable.

[0009] By adopting the above technical solution, after welding is completed, the welding table is lowered. During the descent of the welding table, the lifting component will lift the baffle plate until the inner bottom wall of the inlet tank is flush with the top wall of the welding table. Then, the stepper motor can be started to drive the rotating plate to rotate, that is, to drive the welding table to rotate. The rapid rotation of the welding table can generate centrifugal force to throw the welding slag on the welding table to the edge of the welding table. The welding slag will enter the collection chamber through the inlet tank, thereby completing the cleaning and collection of welding slag. This makes it difficult for welding slag to accumulate on the welding table and avoids cleaning it to the ground, thus preventing the working environment from becoming dirty and messy.

[0010] Optionally, the lifting assembly includes: a limiting block and a plurality of lifting rods. The side wall of the welding table is provided with a limiting groove. The limiting block is slidably connected in the limiting groove and is fixedly connected to the enclosure plate. One end of the lifting rod is fixed to the worktable and the other end abuts against the enclosure plate.

[0011] By adopting the above technical solution, the limiting block can limit the barrier plate, so that when the rotating plate rotates, the barrier plate can rotate along with the rotating plate, without affecting the vertical lifting and lowering of the barrier plate.

[0012] Optionally, the adjustment assembly includes: a rotating plate, an electric cylinder, and a stepper motor. The worktable has a receiving groove, and the bottom of the receiving groove has a receiving hole. The rotating plate is rotatably installed in the receiving groove. The stepper motor is installed in the receiving hole, and the output shaft of the stepper motor is coaxially fixed with the rotating plate. The electric cylinder is fixed on the rotating plate, and the push shaft of the electric cylinder is fixed with the welding table.

[0013] By adopting the above technical solution, during the welding process, a stepper motor can be used to drive the rotating plate to rotate at a certain angle, that is, to drive the welding table to rotate, thereby facilitating the welding robot to perform welding from all directions.

[0014] Optionally, the processing mechanism further includes: a blowing assembly, a driving assembly, and a transmission assembly. The blowing assembly includes: a rotating rod and a fan blade. The inner sidewall of the enclosure is provided with a mounting groove. The rotating rod is rotatably installed in the mounting groove, and the fan blade is fixed on the rotating rod. The driving assembly is disposed between the workbench and the enclosure, and the transmission assembly is disposed between the rotating rod and the driving assembly.

[0015] By adopting the above technical solution, the drive component and transmission component are used to drive the rotating rod to rotate the fan blades, thereby blowing air onto the welding table to further blow the welding slag into the collection chamber, thus improving the cleaning quality of the welding slag.

[0016] Optionally, the drive assembly includes: a support rod, an internal gear, a drive rod, and a drive gear. One end of the support rod is fixed to the workbench, and the other end is fixed to the internal gear. The outer wall of the enclosure is provided with a mounting groove. The drive rod is rotatably installed in the mounting groove, and the drive gear is coaxially sleeved on the drive rod. The drive gear meshes with the internal gear.

[0017] By adopting the above technical solution, during the rotation of the welding table, the drive gear meshes with the internal gear to drive the drive gear to rotate. The rotation of the drive gear will drive the drive rod to rotate, and thus the rotation of the drive rod will drive the transmission component to operate.

[0018] Optionally, the transmission assembly includes a transmission gear and a rotating gear, the mounting groove is connected to the installation groove, the transmission gear is coaxially sleeved on the drive rod, the rotating gear is coaxially sleeved on the rotating rod, and the transmission gear and the rotating gear mesh.

[0019] By adopting the above technical solution, the rotation of the drive rod will sequentially drive the rotation of the transmission gear, the rotating gear and the rotating rod, thereby driving the fan blades to rotate for blowing air.

[0020] Optionally, the blower assembly further includes a baffle net, which is fixed to the opening at the end of the mounting groove away from the placement groove.

[0021] By adopting the above technical solution, the baffle can block the welding slag, making it difficult for the welding slag to enter the installation tank.

[0022] Optionally, a top plate is fixedly provided on the top of the lifting rod, and an annular groove is provided on the top wall of the top plate. Multiple balls are provided in the annular groove, and the balls abut against the enclosure plate.

[0023] By adopting the above technical solution, the ball bearings can reduce the friction force on the fence panel, thereby reducing the wear of the fence panel and ensuring that the lifting rod can lift the fence panel to the required height.

[0024] Optionally, the clamping assembly includes: a clamping plate, a receiving plate, and a pushing spring. The clamping plate is slidably connected to the bottom wall of the clamping platform, the receiving plate is slidably connected to the bottom wall of the clamping platform, and the pushing spring is fixed between the receiving plate and the clamping plate.

[0025] By adopting the above technical solution, the pin is placed between the clamping plates, and then the spring is pushed to push the clamping plates closer to each other to clamp the pin, which facilitates the subsequent welding of the pin to the product.

[0026] Optionally, a tensioning assembly is provided between the welding table and the receiving plate. The tensioning assembly includes a sliding block, a first fixed pulley, a second fixed pulley, and a tension rope. The sliding block is slidably connected to the bottom wall of the welding table. The first fixed pulley is fixed to the worktable, and the second fixed pulley is fixed to the clamping table. One end of the tension rope is fixed to the sliding block and wraps around the first fixed pulley, while the other end passes through the receiving plate and wraps around the second fixed pulley. The end of the tension rope away from the sliding block is fixed to the receiving plate.

[0027] By adopting the above technical solution, during the process of the welding table rising, the welding table will pull the tension rope, which will pull the receiving plate so that the two receiving plates are brought closer to each other, that is, the spring is compressed, so that the clamping plate can further clamp the pin, making the pin less likely to move, thereby ensuring the welding quality of the pin and the product.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. After welding is completed, the welding table is lowered. During the descent, the lifting assembly will lift the baffle plate until the bottom wall of the inlet tank is flush with the top wall of the welding table. Then, the stepper motor can be started to drive the rotating plate to rotate, which in turn drives the welding table to rotate. The rapid rotation of the welding table generates centrifugal force, which throws the welding slag on the welding table to the edge of the welding table. The welding slag will enter the collection chamber through the inlet tank, thus completing the cleaning and collection of the welding slag. This prevents the welding slag from accumulating on the welding table and avoids cleaning it to the ground, thus preventing the working environment from becoming dirty.

[0030] 2. The ball bearings can reduce the friction on the fence panel, thereby reducing the wear of the fence panel and ensuring that the lifting rod can lift the fence panel to the required height.

[0031] 3. Place the pin between the clamping plates, then push the spring to bring the clamping plates closer together to clamp the pin, thus facilitating subsequent welding of the pin to the product. Attached Figure Description

[0037] This application provides a fully automatic welding device for pin welding.

[0038] See Figure 1 A fully automatic welding device for pin welding generally includes: a clamping table 2 and a worktable 1. The clamping table 2 is fixed above the worktable 1 by a rod, and the bottom wall of the clamping table 2 is provided with a clamping assembly 3 for clamping the pin. The clamping assembly 3 includes: a clamping plate 31, a receiving plate 32, and a pushing spring 33, and there are two clamping plates 31, two receiving plates 32, and two pushing springs 33. The clamping plates 31 are slidably connected to the bottom wall of the clamping table 2 and slide in the horizontal direction. In this embodiment, the two clamping plates 31 have grooves for the pin to pass through. In this embodiment, the clamping table 2 is provided with a through hole for placing the pin.

[0039] See Figure 1 The receiving plate 32 is slidably connected to the top wall of the clamping table 2 and slides in the same direction as the clamping plate 31. One end of the pushing spring 33 is fixed to the receiving plate 32 and the other end is fixed to the clamping plate 31. The pushing spring 33 is used to push the two clamping plates 31 closer to each other to clamp the pin, thereby facilitating the subsequent welding of the pin to the product.

[0040] See Figure 2 and Figure 4A welding table 13 is installed on the top of the workbench 1, and an adjustment component 4 is provided between the welding table 13 and the workbench 1. A welding robot is installed on the workbench 1. During welding, the pin is clamped and the product is placed on the welding table 13. Then, the welding robot automatically welds the pin and the product. During the welding process, the welding table 13 can be rotated using the adjustment component 4 to adjust its direction, thereby facilitating the welding robot to perform omnidirectional welding and improving the welding quality.

[0041] See Figure 3 A placement groove is provided at the center of the top wall of the welding table 13, and an electromagnetic plate is installed in the placement groove. Before welding the pin to the product, the product is placed on the electromagnetic plate. The electromagnetic plate can attract the product (the product is metal so that the electromagnetic plate can attract it), thereby fixing the product and making it less likely to move, thus improving the welding quality.

[0042] See Figure 3 The adjustment component 4 includes a rotating plate 41, an electric cylinder 42, and a stepper motor 43. A receiving groove 11 is formed at the center of the top wall of the worktable 1, and a receiving hole 12 is formed at the center of the bottom of the receiving groove 11. The rotating plate 41 is rotatably mounted in the receiving groove 11 via a bearing (not shown in the figure). The stepper motor 43 is mounted in the receiving hole 12, and the output shaft of the stepper motor 43 is coaxially fixed with the rotating plate 41. The electric cylinder 42 is fixedly mounted on the top wall of the rotating plate 41, and the push shaft of the electric cylinder 42 is fixed to the bottom wall of the welding table 13. The electric cylinder 42 is used to push the welding table 13 to rise and fall. After the product is placed on the welding table 13, the electric cylinder 42 is used to push the welding table 13 to rise until the product contacts the pin, thus facilitating welding. During the welding process, the stepper motor 43 can drive the rotating plate 41 to rotate at a certain angle, thereby driving the welding table 13 to rotate, which facilitates welding by the welding robot from all directions.

[0043] In this embodiment, all electrical components are controlled by a controller to achieve automatic adjustment.

[0044] See Figure 3A tensioning assembly 10 is provided between the receiving plate 32 and the welding table 13. The tensioning assembly 10 includes a sliding block 101, a first fixed pulley 102, a second fixed pulley 103, and a tension rope 104. The sliding block 101 is slidably connected to the bottom wall of the welding table 13 and slides along the circumference of the welding table 13. In this embodiment, there are two sliding blocks 101, two first fixed pulleys 102, two second fixed pulleys 103, and two tension ropes 104, each corresponding to one of the receiving plates 32. The first fixed pulley 102 is fixedly installed on the top wall of the workbench 1, and the second fixed pulley 103 is fixedly installed on the bottom wall of the welding table 13. The second fixed pulley 103 is located at the end of the push spring 33 near the clamping plate 31. The first fixed pulley 102 and the second fixed pulley 103 can guide the tension rope 104.

[0045] See Figure 3 One end of the tension rope 104 is fixedly connected to the sliding block 101 and wound around the first fixed pulley 102, while the other end passes through the receiving plate 32 and wound around the second fixed pulley 103. The end of the tension rope 104 away from the sliding block 101 is fixedly connected to the side of the receiving plate 32 closest to the push spring 33. During the ascent of the welding table 13, the welding table 13 pulls the tension rope 104, which in turn pulls the receiving plate 32, causing the two receiving plates 32 to move closer together, thus compressing the push spring 33. This allows the clamping plate 31 to further clamp the pin, making it less prone to movement and ensuring the welding quality between the pin and the product.

[0046] See Figure 3 and Figure 4 A processing mechanism is provided between the welding table 13 and the workbench 1. The processing mechanism includes: a barrier assembly 5, a lifting assembly 6, a blowing assembly 7, a drive assembly 8, and a transmission assembly 9.

[0047] See Figure 3 The enclosure assembly 5 includes an enclosure plate 51, which is fitted onto the welding table 13. The enclosure plate 51 has an annular collection chamber 511 inside for storing welding slag. An annular inlet groove 512 is formed on the inner sidewall of the enclosure plate 51, and the inlet groove 512 communicates with the collection chamber 511. When collecting welding slag, the inner bottom wall of the inlet groove 512 is flush with the top wall of the welding table 13.

[0048] See Figure 3 and Figure 4The lifting assembly 6 includes a limiting block 61 and multiple lifting rods 62. The side wall of the welding table 13 is provided with a limiting groove 515 in the vertical direction. The limiting block 61 is slidably connected in the limiting groove 515 and slides in the vertical direction. The limiting block 61 is fixed to the inner side wall of the enclosure plate 51. The limiting block 61 can limit the enclosure plate 51 so that when the rotating plate 41 rotates, the enclosure plate 51 can rotate with the rotating plate 41 without affecting the vertical lifting and lowering of the enclosure plate 51.

[0049] See Figure 3 One end of the lifting rod 62 is fixed to the top wall of the workbench 1, and the other end abuts against the bottom of the baffle plate 51. In this embodiment, four lifting rods 62 are provided, and the four lifting rods 62 are evenly distributed along the circumference of the baffle plate 51. After welding is completed, the welding table 13 is lowered. During the descent of the welding table 13, the lifting rod 62 will abut against the baffle plate 51 and lift the baffle plate 51 upward until the inner bottom wall of the groove 512 is flush with the top wall of the welding table 13.

[0050] Then the stepper motor 43 can be started to drive the rotating plate 41 to rotate, that is, to drive the welding table 13 to rotate. This operation can use the controller and frequency converter to adjust the speed of the stepper motor 43 to increase the speed of the stepper motor 43. The rapid rotation of the welding table 13 can generate centrifugal force to throw the welding slag on the welding table 13 to the edge of the welding table 13. The welding slag will enter the collection chamber 511 through the inlet trough 512, thereby completing the cleaning and collection of the welding slag, so that the welding slag is not easy to accumulate on the welding table 13, and there is no need to clean it to the ground, so as not to cause dirt and mess to the working environment.

[0051] See Figure 4 Furthermore, a top plate 621 is fixedly installed on the top wall of the lifting rod 62. The top plate 621 is in the form of a complete ring and is located on top of the multiple lifting rods 62. The top wall of the top plate 621 has an annular groove 6211, and multiple balls 6212 are arranged in the annular groove 6211. The balls 6212 abut against the bottom wall of the baffle plate 51. When the baffle plate 51 rotates, the balls 6212 can reduce the friction force on the baffle plate 51, thereby reducing the wear of the baffle plate 51, so as to ensure that the lifting rod 62 can lift the baffle plate 51 to the required height.

[0052] See Figure 4 The blower assembly 7 includes a rotating rod 71 and a fan blade 72. An installation groove 513 is provided on the inner side wall of the baffle plate 51, and when collecting welding slag, the inner bottom wall of the installation groove 513 is flush with the top wall of the welding table 13. The rotating rod 71 is rotatably mounted in the installation groove 513 and is horizontally positioned. The fan blade 72 is fixed to the end of the rotating rod 71 near the welding table 13.

[0053] See Figure 4Furthermore, the blower assembly 7 also includes a baffle 73, which is fixed to the opening at one end of the mounting groove 513 near the welding table 13. The baffle 73 can block the welding slag, so that the welding slag is not easy to enter the mounting groove 513.

[0054] See Figure 3 and Figure 4 The drive assembly 8 includes a support rod 81, an internal gear 82, a drive rod 83, and a drive gear 84. In this embodiment, multiple support rods 81 are provided and arranged along the circumference of the internal gear 82. One end of the support rod 81 is fixed to the top wall of the workbench 1, and the other end is fixed to the bottom wall of the internal gear 82. The support rod 81 provides fixed support for the internal gear 82.

[0055] See Figure 4 The outer wall of the enclosure 51 is provided with a mounting groove 514, and the mounting groove 514 is connected to the installation groove 513. The drive rod 83 is rotatably installed in the mounting groove 514 and is vertically arranged. The drive gear 84 is coaxially sleeved on the drive rod 83, and the drive gear 84 meshes with the internal gear 82.

[0056] See Figure 4 The transmission assembly 9 includes a transmission gear 91 and a rotating gear 92. The transmission gear 91 is coaxially mounted on the drive rod 83, and the rotating gear 92 is coaxially mounted on the rotating rod 71, with the transmission gear 91 and the rotating gear 92 meshing with each other. During the rotation of the welding table 13, the drive gear 84 will rotate, and the rotation of the drive gear 84 will sequentially drive the rotation of the drive rod 83, the transmission gear 91, the rotating gear 92, and the rotating rod 71. The rotation of the rotating rod 71 will drive the fan blade 72 to rotate, thereby blowing air onto the welding table 13 to further blow the welding slag into the collection chamber 511, thus improving the cleaning quality of the welding slag, and eliminating the need for an additional drive source to drive the fan blade 72 to rotate.

[0057] The working principle of the fully automatic welding device for pin welding of this application is as follows: After welding is completed, the welding table 13 is lowered. During the descent of the welding table 13, the lifting rod 62 will abut against the baffle plate 51 and lift the baffle plate 51 upward until the inner bottom wall of the inlet groove 512 is flush with the top wall of the welding table 13. Then the stepper motor 43 can be started to drive the rotating plate 41 to rotate, that is, drive the welding table 13 to rotate. The rapid rotation of the welding table 13 can generate centrifugal force to throw the welding slag on the welding table 13 to the edge of the welding table 13. The welding slag will enter the collection chamber 511 through the inlet groove 512, thereby completing the cleaning and collection of welding slag, so that the welding slag is not easy to accumulate on the welding table 13, and there is no need to clean it to the ground, so as not to cause dirt and mess to the working environment.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
