Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a welding turning machine. Background Technology

[0002] Electric tricycles are a type of transportation converted from bicycles, capable of carrying both passengers and goods. When welding the body of an electric tricycle, the base and side panels must first be spot-welded before full welding. Therefore, during full welding, the body needs to be flipped to different positions to adjust the welding location and facilitate the work. However, some existing methods place the body on a welding platform and flip it to adjust its position when welding different areas. This not only increases the labor intensity for workers but also reduces production efficiency. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a welding turning machine that facilitates the turning and position adjustment of electric tricycles, thereby improving production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a welding turning machine, comprising:

[0005] stand;

[0006] A tilting table, which is rotatably mounted on a frame;

[0007] There are two sliding tables, which are symmetrically and movable on both sides of the bottom of the frame. The sliding tables are equipped with sliding grooves.

[0008] There are two pressure plate assemblies, with one pressure plate assembly slidably installed in each slide groove.

[0009] The turning table includes a turning groove set on a frame, a welding plate rotatably set inside the turning groove, a turning shaft passing through the welding plate, a turning motor set on the inner wall of the turning groove, and the turning shaft coaxially connected to the output shaft of the turning motor.

[0010] The pressure plate assembly includes multiple pressure plate seats that are slidably arranged in parallel slots within the slide groove. An adjustment plate is rotatably hinged above the pressure plate seats. An extension seat is slidably sleeved on the outside of the adjustment plate. A clamping plate is rotatably arranged on each of the opposite side walls of the extension seat. A clamping cylinder is arranged on the side wall of the pressure plate seat near the end of the frame.

[0011] Preferably, the welding table is provided with multiple through slots spaced parallel to each other. The length direction of the through slots is the same as the length direction of the axis of the output shaft of the flip motor, which facilitates the collection of welding slag generated during the welding of the electric tricycle body and prevents the welding slag from accumulating on the welding table.

[0012] Preferably, the sliding table is rotatably connected to the bottom of the side wall of the frame via a rotating shaft. A sliding groove is provided on the end of the sliding table away from the rotating shaft. Multiple guide rods are arranged parallel to each other in the sliding groove. The pressure plate seat is slidably mounted on the guide rods. The position of the sliding table can be adjusted as needed to facilitate the welding of the electric tricycle carriage placed on the welding table.

[0013] Preferably, a push cylinder is embedded in the inner wall of the chute, and two pressure plate seats are provided, which are spaced apart along the movement direction of the piston rod of the push cylinder. The piston rod of the push cylinder passes through the pressure plate seat near the end of the push cylinder. A movable sleeve rod is coaxially provided on the piston rod of the push cylinder, and a connecting rod is provided through the pressure plate seat away from the end of the push cylinder. The piston rod, connecting rod, and movable sleeve rod of the push cylinder are coaxial. A groove with a diameter adapted to the connecting rod is provided on the end of the movable sleeve rod away from the push cylinder. The position of the pressure plate seat can be adjusted by the push cylinder, which is convenient for fixing the electric tricycle carriage of different sizes by means of a clamping plate, thereby improving the efficiency of welding operations.

[0014] Preferably, the length direction of the guide rod is the same as the movement direction of the piston rod of the push cylinder, so that when the position of the pressure plate seat is adjusted by pushing the cylinder, the pressure plate seat can be ensured to slide smoothly.

[0015] Preferably, the adjusting plate is rotatably hinged above the pressure plate seat via a rotating shaft with a nut, which facilitates the adjustment of the adjusting plate position on the pressure plate seat and then fixation.

[0016] Preferably, the extension seat has a central column on each of its two opposing side walls, and a through groove on the clamping plate. The central column extends into the through groove from the end away from the extension seat. The extension seat also has multiple internal threaded holes on each of its two opposing side walls, and multiple positioning bolts are movably installed in the internal threaded holes. The positioning bolts extend through the through groove into the corresponding internal threaded holes. This allows the clamping plate to be adjusted according to the size of the electric tricycle carriage, and then fixed with the positioning bolts. This facilitates the use of the clamping plate to fix the electric tricycle carriage placed on the welding platform.

[0017] Preferably, the internal threaded holes are rectangularly distributed to facilitate adjustment of the position of the clamping plate.

[0018] Preferably, the welding platform has a fixing groove on each of its opposite end sidewalls, and a positioning rod is movably inserted through the fixing groove. The pressure plate seat is provided with a slider that matches the fixing groove. The slider is slidably disposed in the fixing groove, and the positioning rod moves through the slider. This facilitates maintaining the horizontal sliding adjustment position of the pressure plate seat stably when the sliding table does not need to be rotated.

[0019] Preferably, a buffer sleeve 1 is coaxially sleeved on the piston rod of the clamping cylinder. A connecting plate is rotatably arranged on the end of the buffer sleeve 1 near the clamping cylinder. A buffer sleeve 2 is arranged on the end of the connecting plate away from the buffer sleeve 1. The axis of the buffer sleeve 1 is parallel to the axis of the buffer sleeve 2, so as to facilitate clamping and positioning of the electric tricycle carriage of different sizes after it is placed on the welding table by the buffer sleeve 1 and / or the buffer sleeve 2.

[0020] The beneficial effects of the present invention are as follows: 1. The present invention can adjust the position of the welding table by flipping the tilting groove, and with the cooperation of the pressure plate assembly, not only can the carriage of the electric tricycle be flipped according to the welding needs, but the carriage of the electric tricycle can also be fixed after flipping, thereby improving the welding efficiency.

[0021] 2. The distance between the two pressure plate seats can be adjusted by sliding within the groove according to the different sizes of the electric tricycle carriage, which facilitates the use of clamps to fix the electric tricycle carriage, thereby improving the applicability and versatility of fixing the electric tricycle carriage before welding.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1 to 4As shown, the present invention provides a welding turning machine, including a frame 1; a turning table 2 rotatably mounted on the frame 1; two sliding tables 3 are provided, which are symmetrically and movably mounted on both sides of the bottom of the frame 1, and each sliding table 3 is provided with a sliding groove 31; two pressure plate assemblies 4 are provided, and each sliding groove 31 is slidably mounted with a pressure plate assembly 4; the turning table 2 includes a turning groove 21 mounted on the frame 1, a welding plate 22 is rotatably mounted in the turning groove 21, a turning shaft 23 is passed through the welding plate 22, a turning motor 24 is mounted on the inner wall of the turning groove 21, and the turning shaft 23 is coaxially connected to the output shaft of the turning motor 24; the pressure plate assembly 4 includes a plurality of pressure plate seats 41 slidably mounted in parallel and spaced within the sliding groove 31, an adjusting plate 42 is rotatably hinged above the pressure plate seat 41, an extension seat 43 is slidably mounted on the outside of the adjusting plate 42, and a clamping plate 44 is rotatably mounted on each of the opposite side walls of the extension seat 43, and a clamping cylinder 45 is mounted on the side wall of the pressure plate seat 41 near the end of the frame 1.

[0036] When welding the electric tricycle body (the bottom plate and side plates of the electric tricycle body are spot welded), the bottom plate of the electric tricycle body can be placed on the welding table 22 first. Depending on the size of the electric tricycle body, the position of the pressure plate seat 41 can be adjusted by sliding it in the slide groove 31. The adjusting plate 42 can be rotated so that the positions of the extension seat 43 and the clamping plate 44 correspond vertically to the positions of the side plates of the electric tricycle body. At this time, the clamping plate 44 can be pressed against the side plates of the electric tricycle body (the clamping plate 44 near the end of the electric tricycle body can be provided with a groove that matches the width of the side plates of the electric tricycle body, so that the groove can be inserted into the outside of the side plates of the electric tricycle body to improve the fixation). At the same time, the clamping cylinder 45 is activated to clamp the electric tricycle body, which helps to maintain the stability of the position between the side plates and the bottom plate of the electric tricycle body, making it easier to carry out welding operations.

[0037] The frame 1 can also be equipped with multiple pneumatic cylinders (pneumatic cylinders are existing technology, so they will not be described in detail here), which facilitates the rotation and adjustment of the electric tricycle carriage when the tilting motor 24 is started to drive the welding table 22 to rotate and adjust its position in the tilting groove 21 with the tilting shaft 23 as the axis (the position of the adjustment plate 42 and the extension seat 43 can also be adjusted synchronously according to the tilting position of the welding table 22, so that the extension seat 43 can be used to press and fix the tilted electric tricycle carriage). This allows the operator to weld at different positions of the electric tricycle carriage, improving the ease of operation.

[0038] Example 2

[0039] Based on Example 1, such as Figures 1 to 2As shown, multiple through slots 25 are arranged parallel to each other on the welding table 22. The length direction of the through slots 25 is the same as the length direction of the axis of the output shaft of the flip motor 24. When welding the electric tricycle carriage on the welding table 22, the welding slag generated can fall onto the bottom surface of the frame 1 through the through slots 25 (or facilitate the cleaning of the welding slag falling on the welding table 22, and fall onto the bottom surface of the frame 1 through the through slots 25), which is convenient for collection and prevents the welding slag from accumulating on the welding table 22 and affecting the placement of the electric tricycle carriage before welding.

[0040] Example 3

[0041] Based on Example 1, such as Figure 1 , Figures 3 to 4 , Figures 6 to 7 As shown, the sliding table 3 is rotatably connected to the bottom of the side wall of the frame 1 via a rotating shaft 32. A sliding groove 31 is located at the end of the sliding table 3 away from the rotating shaft 32. Multiple guide rods 311 are arranged parallel to each other in the sliding groove 31. The pressure plate seat 41 is slidably mounted on the guide rods 311. A push cylinder 33 is embedded in the inner wall of the sliding groove 31. There are two pressure plate seats 41, and the two pressure plate seats 41 are distributed at intervals along the movement direction of the piston rod of the push cylinder 33. The piston rod of the push cylinder 33 passes through and is close to the push cylinder. The pressure plate seat 41 at the end of the cylinder 33 has a movable sleeve rod 331 coaxially arranged on the piston rod of the cylinder 33. A connecting rod 332 is arranged through the pressure plate seat 41 away from the end of the cylinder 33. The piston rod, connecting rod 332 and movable sleeve rod 331 of the cylinder 33 are coaxial. The end of the movable sleeve rod 331 away from the cylinder 33 has a tube groove 333 that matches the diameter of the connecting rod 332. The length direction of the guide rod 311 is the same as the movement direction of the piston rod of the cylinder 33.

[0042] The distance between the two pressure plate seats 41 can be adjusted within the slide groove 31 according to the different sizes of the electric tricycle carriage, so as to facilitate the use of the clamping plate 44 to fix the electric tricycle carriage, thereby improving the applicability of fixing the electric tricycle carriage before welding.

[0043] If it is necessary to adjust the position of the two pressure plate seats 41 at the same time, first put the movable sleeve rod 331 on the connecting rod 332, and then start the push cylinder 33 to make the two pressure plate seats 41 move synchronously for position adjustment.

[0044] Alternatively, internally threaded sleeves can be rotatably installed at both ends of the movable sleeve 331 along its length. The connecting rod 332 has an externally threaded rod structure, and a threaded rod is coaxially installed on the piston rod of the pushing cylinder 33. The threaded rods on the connecting rod 332 and the piston rod of the pushing cylinder 33 are respectively threadedly connected to the internally threaded sleeves at both ends of the movable sleeve 331 along its length. As needed, the distance between the two pressure plate seats 41 can be adjusted by rotating the internally threaded sleeves. At this time, the pushing cylinder 33 can be activated to make the two pressure plate seats 41 move synchronously for position adjustment.

[0045] A motor for driving the rotating shaft 32 can be installed at the bottom of the side wall of the platform 1, so as to facilitate the rotation and position adjustment of the sliding table 3.

[0046] Example 4

[0047] Based on Example 1, such as Figures 1 to 4 As shown, the adjusting plate 42 is rotatably hinged above the pressure plate seat 41 via a rotating shaft 46 with a nut. This allows the position of the adjusting plate 42 to be fixed by rotating it on the pressure plate seat 41 according to the welding requirements of the electric tricycle body (rotating the adjusting plate 42 around the rotating shaft 46 with a nut), and then tightening the nut in the rotating shaft 46 with a nut. This makes it easy to use the clamping plate 44 to fix the electric tricycle body before welding.

[0048] A lifting cylinder can also be provided above the pressure plate seat 41. The adjusting plate 42 is rotatably hinged to the piston rod of the lifting cylinder through the rotating shaft 46 with a nut. Thus, the lifting cylinder can drive the adjusting plate 42 and the extension seat 43 to adjust their positions in the vertical direction, which makes it convenient to clamp and fix electric tricycle carriages of different shapes and sizes before welding.

[0049] Example 5

[0050] Based on Example 1, such as Figure 1 , Figure 4 , Figures 8 to 9 As shown, the extension seat 43 has a central column 431 on each of its two opposing side walls, and a through groove 441 on the clamping plate 44. The end of the central column 431 away from the extension seat 43 moves through the through groove 441. The extension seat 43 also has multiple internal threaded holes 432 on each of its two opposing side walls. Multiple positioning bolts 433 are movably installed in the internal threaded holes 432. The positioning bolts 433 move through the through groove 441 to the corresponding internal threaded holes 432. The internal threaded holes 432 are rectangularly distributed.

[0051] Depending on the size of the electric tricycle carriage, the position of the clamping plate 44 can be adjusted by rotating or moving it outside the middle column 431 (that is, moving the end of the middle column 431 away from the extension seat 43 within the through groove 441 to different positions). After adjusting the clamping plate 44, the positioning bolt 433 is then connected to the corresponding internal threaded hole 432 through the through groove 441 on the clamping plate 44. This will connect and fix the clamping plate 44 to the extension seat 43, thus allowing the clamping plate 44 to be used to fix the electric tricycle carriage placed on the welding platform 22.

[0052] Example 6

[0053] Based on Example 1, such as Figure 1 , Figure 3 As shown, the welding platform 22 has fixed grooves 221 on its opposite end sidewalls. A positioning rod 222 is movably inserted through the fixed groove 221. A slider 223 adapted to the fixed groove 221 is provided on the pressure plate seat 41. The slider 223 is slidably disposed in the fixed groove 221, and the positioning rod 222 movably inserts through the slider 223. When it is not necessary to rotate the sliding table 3, the positioning rod 222 can be inserted through the slider 223, which helps to keep the pressure plate seat 41 in a stable position when sliding along the length of the fixed groove 221 (i.e., the slider 223 slides in the fixed groove 221). When it is necessary to rotate the sliding table 3, the positioning rod 222 can be removed. When the sliding table 3 is rotated, the slider 223 can be rotated out of the fixed groove 221.

[0054] Example 7

[0055] Based on Example 1, such as Figure 5 As shown, a buffer sleeve 451 is coaxially sleeved on the piston rod of the clamping cylinder 45. A connecting plate 452 is rotatably mounted on the end of the buffer sleeve 451 near the clamping cylinder 45, and a buffer sleeve 453 is mounted on the end of the connecting plate 452 away from the buffer sleeve 451. The axis of the buffer sleeve 451 is parallel to the axis of the buffer sleeve 453. When the electric tricycle carriage is placed on the welding platform 22, the clamping cylinder 45 can be activated to push the buffer sleeve 451, the connecting plate 452, and the buffer sleeve 453 to move simultaneously toward the electric tricycle carriage, so that the buffer sleeve 451 and / or the buffer sleeve 453... 3. It abuts against the electric tricycle carriage, thus fixing the electric tricycle carriage; or, depending on the different sizes of the electric tricycle carriage, the position of the buffer sleeve 453 can be adjusted by rotating the connecting plate 452 outside the buffer sleeve 451 (the connecting plate 452 is rotatably connected to the buffer sleeve 451 near the tightening cylinder 45 by a damping hinge, so that it can stop at any position after rotation; the damping hinge is existing technology, so it will not be described in detail here), thus making it easy for the buffer sleeve 453 to abut against the electric tricycle carriage according to different external sizes of the electric tricycle carriage.

[0056] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
