Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to an inclined welding device. Background Technology

[0002] During the production of sanitation vehicles, different components need to be welded together. Currently, many welding torches used in welding production processes are fixed in a straight up-down position and cannot be tilted. This makes the welding position and method relatively limited, and the welding position is relatively fixed. When welding operations need to be performed in different positions, it is not convenient to adjust the position of the welding torch, resulting in poor applicability. Summary of the Invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a tilting welding device, which has the advantages of facilitating the adjustment of the tilt angle of the welding torch and improving its applicability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an inclined welding device, comprising:

[0005] Fixed base;

[0006] Adjust the sliding plate; the sliding plate is set on the fixed base.

[0007] A tilt angle adjustment component is mounted on the side wall of the adjustment slide.

[0008] The adjusting rod moves through the adjusting slide.

[0009] An adjustment disc assembly is installed on the side wall of the adjustment slide away from the tilt angle adjustment assembly, and the two ends of the adjustment rod along its length are connected to the tilt angle adjustment assembly and the adjustment disc assembly, respectively.

[0010] The welding torch is movably connected to the adjusting rod at its middle position, and the welding torch is movably mounted on the adjusting plate assembly.

[0011] The tilt angle adjustment component includes a drive motor mounted on the side wall of the adjustment slide, an active bevel gear mounted on the output shaft of the drive motor, and a driven bevel gear meshing with the active bevel gear mounted on the end of the adjustment rod near the drive motor.

[0012] The adjustment plate assembly includes a circular base plate disposed on the side wall of the tilt angle adjustment assembly. A semi-circular groove is provided on the circular base plate, and a circular ring is disposed inside the semi-circular groove. The end of the welding torch away from the torch head is movably connected to both the circular ring and the adjustment rod.

[0013] Preferably, the fixed base is provided with a vertical groove, and the adjusting slide is vertically slidably disposed in the groove, so as to facilitate the sliding adjustment of the position of the adjusting slide within the groove, so as to adjust the welding gun according to different welding position requirements.

[0014] Preferably, the driven bevel gear is rotatably mounted on the side wall of the adjusting slide plate away from the adjusting plate assembly, and the adjusting rod slides through the driven bevel gear. The adjusting rod is coaxial with the driven bevel gear, which facilitates sliding the adjusting rod so as to adjust the distance between the welding torch and the fixed seat according to the welding requirements.

[0015] Preferably, the semi-circular groove, the ring, the circular base, and the adjusting rod are coaxial, which helps to maintain the stability of the welding torch position adjustment.

[0016] Preferably, the welding torch has multiple mounting slots spaced along its length that are adapted to the adjusting rod. The adjusting rod, located away from the driven bevel gear, moves through the circular base and is inserted into the corresponding mounting slot. A locking bolt is also threaded onto the end of the adjusting rod away from the driven bevel gear. The locking bolt moves through the corresponding mounting slot and abuts against the outer peripheral wall of the welding torch. A limiting plate is movably inserted into the end of the adjusting rod away from the driven bevel gear. The length of the limiting plate is greater than the radius of the semi-circular groove, and the position of the limiting plate away from the adjusting rod matches the position of the arc-shaped opening of the semi-circular groove. This facilitates the connection between the welding torch and the adjusting rod and helps maintain the stability of the welding torch position during welding operations.

[0017] Preferably, the welding torch is provided with a connecting rod at the end away from the torch head. The connecting rod is movably disposed in a semi-circular groove at the end away from the welding torch. An arc-shaped opening groove is provided at the end of the connecting rod away from the welding torch. The inner peripheral wall of the arc-shaped opening groove contacts the outer peripheral wall of the ring, which facilitates the synchronous sliding of the arc-shaped opening groove on the outer peripheral wall of the ring when the welding torch is rotated to adjust its position, thus helping to maintain the stability of the welding torch position.

[0018] Preferably, the connecting rod near the welding torch end has an external threaded rod structure, the connecting rod near the welding torch end is threadedly connected to the welding torch, and the connecting rod away from the welding torch end is rotatably connected to the arc-shaped opening groove, which facilitates the adjustment of the distance between the connecting rod and the welding torch, and allows the welding torch to be adjusted in position simultaneously when the position of the sliding adjustment rod is adjusted.

[0019] Preferably, the ring has multiple angle limiting holes evenly distributed along its circumference, and two angle limiting rods are movably inserted into the multiple angle limiting holes. The end of the limiting plate away from the adjusting rod is located between the two angle limiting rods, so that the two angle limiting rods can be inserted into the angle limiting holes at the corresponding positions as needed, so that the end of the limiting plate away from the adjusting rod can always be kept between the two angle limiting rods, so as to limit the position when the welding gun is rotated and adjusted.

[0020] Preferably, the limiting plate has a notch at the end away from the adjusting rod, the ring is located inside the notch, and an extension rod is provided on the notch. The extension rod is located between the two angle limiting rods, so that the two angle limiting rods can be inserted into the angle limiting holes at the corresponding positions as needed, so that the extension rod can be kept between the two angle limiting rods, so as to limit the position when the welding gun is rotated and adjusted.

[0021] Preferably, both ends of the semi-circular groove arc opening are provided with stoppers, which helps to keep the ring located within the semi-circular groove.

[0022] The beneficial effects of the present invention are as follows: 1. By starting the drive motor to drive the adjusting rod to rotate, the welding torch can be rotated, thereby realizing various tilt angle changes of the welding torch and improving its applicability.

[0023] 2. Alternatively, the two angle limiting rods can be inserted into the corresponding angle limiting holes so that the limiting plate can remain between the two angle limiting rods when it is away from the adjusting rod end, so as to limit the position when the welding gun is rotated and adjusted.

Detailed Implementation

[0035] 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.

[0036] Example 1

[0037] like Figures 1 to 5 As shown, the present invention provides an inclined welding device, including a fixed base 1; an adjusting slide plate 2 slidably disposed on the fixed base 1; an inclined angle adjusting component 3 disposed on the side wall of the adjusting slide plate 2; an adjusting rod 4 movably passing through the adjusting slide plate 2; an adjusting plate assembly 5 disposed on the side wall of the adjusting slide plate 2 away from the inclined angle adjusting component 3, with the two ends of the adjusting rod 4 in the length direction respectively connected to the inclined angle adjusting component 3 and the adjusting plate assembly 5; a welding torch 6 movably connected to the adjusting rod 4 at its middle position, and the welding torch 6 movably disposed on the adjusting plate assembly 5; the inclined angle adjusting component 3 includes a drive motor 31 disposed on the side wall of the adjusting slide plate 2, a drive bevel gear 32 disposed on the output shaft of the drive motor 31, and a driven bevel gear 33 meshing with the drive bevel gear 32 disposed on the end of the adjusting rod 4 near the drive motor 31; the adjusting plate assembly 5 includes a circular base 51 disposed on the side wall of the inclined angle adjusting component 3, a semi-circular groove 52 disposed on the circular base 51, a circular ring 53 disposed in the semi-circular groove 52, and the end of the welding torch 6 away from the torch head being movably connected to both the circular ring 53 and the adjusting rod 4.

[0038] Before welding, the fixed base 1 is fixed in the desired position. The drive motor 31 drives the active bevel gear 32 to rotate, which in turn drives the driven bevel gear 33 and the adjusting rod 4 to rotate. This allows the welding torch 6 to rotate and adjust its position according to the welding position requirements, with the axis of the adjusting rod 4 as the axis (i.e., the welding torch 6 can achieve different tilt angles relative to the circular base 51). While the welding torch 6 is rotating, the end of the welding torch 6 away from the torch head can slide on the ring 53 in the semi-circular groove 52, which helps to keep the position of the welding torch 6 stable during rotation. The position of the adjusting slide plate 2 on the fixed base 1 can also be adjusted to adjust the position of the welding torch 6.

[0039] Example 2

[0040] Based on Example 1, such as Figure 4 As shown, a slide groove 21 is vertically provided on the fixed base 1, and the adjusting slide plate 2 is vertically slidably disposed in the slide groove 21; this facilitates the sliding adjustment of the position of the adjusting slide plate 2 within the slide groove 21, so as to adjust the position of the welding torch 6 according to different welding heights, thereby improving the versatility of application; a lifting cylinder or a lead screw and nut assembly for driving the adjusting slide plate 2 to move vertically can be provided at the bottom of the slide groove 21 (both the lifting cylinder and the lead screw and nut assembly are existing technologies, so they will not be described in detail here).

[0041] Example 3

[0042] Based on Example 1, such as Figure 1 , Figures 3 to 5 As shown, the driven bevel gear 33 is rotatably mounted on the side wall of the adjusting slide plate 2 away from the adjusting plate assembly 5, and the adjusting rod 4 slides through the driven bevel gear 33. The adjusting rod 4 and the driven bevel gear 33 are coaxial. This allows the adjusting rod 4 to be slidably adjusted on the adjusting slide plate 2 (so that the adjusting rod 4 moves along the length of the axis of the driven bevel gear 33), thereby adjusting the distance between the welding torch 6 and the fixed seat 1 according to the welding position requirements, improving the diversity of welding positions. At the same time, in order to fix the position of the adjusting rod 4 after it slides on the adjusting slide plate 2, a connecting bolt that penetrates into the adjusting rod 4 can be provided on the side wall of the adjusting plate assembly 5 (near the end of the driven bevel gear 33). That is, before the adjusting rod 4 is slidably adjusted on the adjusting slide plate 2, the connecting bolt can be separated from the adjusting rod 4. After the adjusting rod 4 is slidably adjusted on the adjusting slide plate 2, the connecting bolt can be inserted into the adjusting rod 4 to fix the position of the adjusting rod 4 and prevent the adjusting rod 4 from rotating during welding operations.

[0043] Example 4

[0044] Based on Example 1, such as Figure 1As shown, the semi-circular groove 52, the ring 53, the circular base 51, and the adjusting rod 4 are coaxial; this helps to keep the position of the welding torch 6 stable when adjusting the position of the adjusting rod 4; at the same time, it allows the welding torch 6 to rotate and adjust its position with the axis of the adjusting rod 4 as the axis, so as to achieve different tilt angles.

[0045] Example 5

[0046] Based on Example 1, such as Figures 1 to 4 , Figure 8 As shown, the welding torch 6 has multiple mounting slots 62 spaced along its length to match the adjusting rod 4. The end of the adjusting rod 4 away from the driven bevel gear 33 moves through the circular base 51 and is inserted into the corresponding mounting slot 62. The end of the adjusting rod 4 away from the driven bevel gear 33 is also threaded with a locking bolt 64. The locking bolt 64 moves through the corresponding mounting slot 62 and abuts against the outer peripheral wall of the welding torch 6. A limiting plate 41 is inserted into the end of the adjusting rod 4 away from the driven bevel gear 33. The length of the limiting plate 41 is greater than the radius of the semi-circular groove 52, and the position of the end of the limiting plate 41 away from the adjusting rod 4 matches the position of the arc-shaped opening of the semi-circular groove 52. Multiple angle limiting holes 531 are evenly distributed along the circumference of the ring 53. Two angle limiting rods 532 are inserted into the multiple angle limiting holes 531. The end of the limiting plate 41 away from the adjusting rod 4 is located between the two angle limiting rods 532.

[0047] When it is necessary to adjust the vertical position of the welding torch 6, the connecting rod 63 can be removed first (that is, the connecting rod 63 and the welding torch 6 can be separated); then, according to the installation position requirements, the end of the adjusting rod 4 away from the driven bevel gear 33 can be inserted into the mounting groove 62 on the welding torch 6 at the corresponding position; then tighten the locking bolt 64 and the threaded connection between the end of the adjusting rod 4 away from the driven bevel gear 33, so that the locking bolt 64 abuts against the outer peripheral wall of the welding torch 6.

[0048] When the tilt angle of the welding torch 6 needs to be adjusted, the adjusting rod 4 can be rotated, and the welding torch 6 can rotate simultaneously with the adjusting rod 4 to achieve the tilt angle adjustment. When it is necessary to limit the range of rotation of the welding torch 6, the position of the end of the limiting plate 41 away from the adjusting rod 4 can be matched with the position of the arc-shaped opening of the semi-circular groove 52. At the same time, the two angle limiting rods 532 are respectively inserted into the two angle limiting holes 531, and the end of the limiting plate 41 away from the adjusting rod 4 is located between the two angle limiting rods 532. At this time, when the welding torch 6 is rotated, the two angle limiting rods 532 can limit the end of the limiting plate 41 away from the adjusting rod 4.

[0049] The limiting plate 41 has a notch 411 at the end away from the adjusting rod 4. The ring 53 is located inside the notch 411. An extension rod 412 is provided on the notch 411 and is located between the two angle limiting rods 532. When the two angle limiting rods 532 are inserted into the angle limiting holes 531 at the corresponding positions, the extension rod 412 can be kept between the two angle limiting rods 532 so as to limit the position when the welding gun 6 is rotated and adjusted. At the same time, when the welding gun 6 is rotated, the extension rod 412 and the limiting plate 41 can rotate synchronously, and the notch 411 can move outside the ring 53 without interfering with the ring 53.

[0050] Since the limiting plate 41 is movably inserted at the end of the adjusting rod 4 away from the driven bevel gear 33, when the limiting plate 41 is not needed, the limiting plate 41 can be slidably adjusted at the end of the adjusting rod 4 away from the driven bevel gear 33, so that the distance from both ends of the limiting plate 41 in the length direction to the adjusting rod 4 is the same, and both angle limiting rods 532 can be removed from the angle limiting hole 531. At this time, when the adjusting rod 4 is rotated, neither end of the limiting plate 41 in the length direction will interfere with the semi-circular groove 52.

[0051] Example 6

[0052] Based on Example 1, such as Figure 1 , Figures 3 to 7 , Figure 9 As shown, a connecting rod 63 is provided at the end of the welding torch 6 away from the torch head. The end of the connecting rod 63 away from the welding torch 6 is movably disposed in the semi-circular groove 52. An arc-shaped opening groove 61 is provided at the end of the connecting rod 63 away from the welding torch 6. The inner peripheral wall of the arc-shaped opening of the arc-shaped opening groove 61 contacts the outer peripheral wall of the ring 53. The end of the connecting rod 63 near the welding torch 6 has an external threaded rod structure. The end of the connecting rod 63 near the welding torch 6 is threadedly connected to the welding torch 6. The end of the connecting rod 63 away from the welding torch 6 is rotatably connected to the arc-shaped opening groove 61. When the welding torch 6 is rotated to adjust its position (that is, when the welding torch 6 rotates to adjust its position about the axis of the adjusting rod 4), the arc-shaped opening groove 61 slides synchronously on the outer peripheral wall of the ring 53, which helps to maintain the stability of the position of the welding torch 6.

[0053] Since the connecting rod 63 is threadedly connected to the welding torch 6 at the end near the welding torch 6, and the connecting rod 63 moves through the welding torch 6 at the end near the welding torch 6, it is convenient to rotate the connecting rod 63 at the same time when the adjusting rod 4 moves along the length of the driven bevel gear 33 axis on the adjusting slide plate 2. Thus, the distance between the welding torch 6 and the fixed seat 1 can be adjusted according to the welding position requirements. (The connecting rod 63 at the end near the welding torch 6 has an external threaded rod structure, and the external thread of the connecting rod 63 at the end near the welding torch 6 has multiple rotating nuts, which helps to fix the position of the welding torch 6 at the end of the connecting rod 63 near the welding torch 6.)

[0054] Both ends of the arc-shaped opening of the semi-circular groove 52 are provided with stop blocks 521; this helps to keep the ring 53 within the semi-circular groove 52.

[0055] 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.
