Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to a manual moving mechanism of an orbital welding device. Background Art

[0002] A large amount of welding operations are involved in the manufacturing process of containers. In the traditional method, manual welding is mainly used. In order to improve welding efficiency and save labor costs, automatic welding equipment has gradually replaced manual operations. The orbital moving automatic welding device is a relatively common equipment at present. The track is laid on the ground of the operation site, the welding device is installed on the sliding plate, sliders are arranged at the bottom of the sliding plate, and the sliders move along the track. After reaching the designated operation position, the positions of the sliders are fixed. After the automatic welding equipment completes one welding operation, it can move along the track to the next welding position again through the cooperation of the sliders and the track.

[0003] In the prior art, controlling the movement of the welding device along the track usually adopts the method of meshing a speed reducer gear set with a rack arranged along the track, and the purpose of moving the welding equipment to the designated position is achieved by controlling the start and stop of the motor. However, relying solely on the motor start and stop control method, the moving speed is relatively slow. Especially in the case where there are multiple automatic welding devices on the track, setting a manual moving device is more convenient for the rapid movement of the welding equipment. Summary of the Utility Model

[0004] The utility model discloses a manual moving mechanism of an orbital welding device, which can quickly move the welding device to the designated position on the track.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A manual moving mechanism of an orbital welding device includes a rack installed on the track, a slider sliding along the track, and a sliding plate fixedly connected to the slider. An activity plate is arranged on the sliding plate. One end of the activity plate is installed on the sliding plate in a hinged manner, and the activity plate can rotate up and down along the hinge point. A speed reducer seat is fixedly installed on the activity plate, a motor is installed on the speed reducer seat, a helical gear is installed on the output shaft of the motor, and the helical gear can be meshed with the rack. A manual clutch lever is arranged at the hinged end of the activity plate. A swing block is arranged at one end of the manual clutch lever, and the swing block is hinged to the sliding plate. Pressing the clutch lever can make the swing block rotate, and the rotation of the swing block can make the activity plate lift upward along the hinge point to separate the helical gear from the rack.

[0007] Further, a long-shaped relief hole is opened at the free end of the activity plate. A positioning post is arranged in the relief hole. The bottom of the positioning post is fixed on the sliding plate. The positioning post perpendicularly protrudes from the relief hole on the sliding plate. A spring is sleeved on the positioning post. The upper end of the spring is fixed on the positioning post, and the lower end of the spring abuts against the activity plate. The spring is in a compressed state.

[0008] Further, fixed seats are symmetrically arranged on the sliding plate, and the two fixed seats are connected by a fixed shaft. A connecting block is provided on the movable plate, and the connecting block is installed on the fixed shaft in a hinged manner. The movable plate can rotate up and down along the fixed shaft.

[0009] Further, two connecting blocks are arranged at intervals, and the two connecting blocks are also connected by a rotating shaft. A gap is left between the rotating shaft and the fixed shaft. A through hole is opened on the swinging block, and the swinging block is hinged and installed on the rotating shaft.

[0010] Further, the clutch lever is divided into a hand rocker and a connecting rod. The connecting rod is parallel to the direction of the rotating shaft. The hand rocker is connected to the connecting rod and forms an obtuse angle. The swinging block is fixedly installed at one end of the connecting rod. The swinging block is of a strip-shaped structure, and an inclined surface is provided on the swinging block.

[0011] For the manual moving mechanism designed by the utility model, after pressing the clutch lever, the movable plate can be tilted upward by the rotation of the swinging block. After the movable plate is turned upward, the originally meshing helical gear and the rack are separated. Only by pushing the sliding plate can the welding device be quickly moved to the designated position, with simple operation, convenience and rapidity. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] For the movement of the orbital welding device along the orbit in this embodiment, a manual moving mechanism is designed, as Figures 1 to 5 shown. A double orbit 1 is laid on the ground. A rack 4 is arranged on the side of the orbit 1 along the length direction of the orbit 1. A slider 5 is arranged on the orbit 1, and a slide plate 6 is fixedly installed on the slider 5. A welding torch 2, a mounting bracket, and a moving mechanism are respectively arranged on the slide plate 6. A laser sensor 3 is arranged on the mounting bracket. The moving mechanism includes a motor 8, a speed reducer, a helical gear 7, a movable plate 10, and a clutch lever 12. Among them, the movable plate 10 is arranged on the top surface of the slide plate 6, and one end of the movable plate 10 is installed on the slide plate 6 in a hinged manner, and the other end of the movable plate 10 is a free end and is not fixed, so that the movable plate 10 can rotate up and down by a certain angle along the hinge point. A speed reducer seat 9 is fixedly installed on the top surface of the movable plate 10. The motor 8 and the speed reducer are installed on the speed reducer seat 9. The output shaft of the motor 8 is downward, and a helical gear 7 is arranged at the end of the output shaft. When the movable plate 10 is completely attached to the slide plate 6, the helical gear 7 just meshes with the rack 4. Under the rotation of the motor 8, the slide plate 6 can be driven to move along the orbit 1 through the meshing of the helical gear 7 and the rack 4.

[0021] Continuing from the above, in order to quickly move the slide plate 6, it is necessary to separate the helical gear 7 from the rack 4. In this embodiment, a manual method is adopted to achieve the separation of the two, that is: a manual clutch lever 12 is arranged on one side of the hinged end of the movable plate 10, and a swing block 18 is arranged at one end of the clutch lever 12, so that the swing block 18 can rotate and pry the movable plate 10 to rotate upward during the rotation, thereby separating the helical gear 7 from the rack 4.

[0022] The manual moving mechanism is specifically arranged as follows: elongated relief holes 14 are respectively opened on both sides of the free end of the movable plate 10. A positioning post 11 is arranged in each relief hole 14. The positioning post 11 is perpendicular to the slide plate 6. The bottom of the positioning post 11 is fixed on the slide plate 6, so that the positioning post 11 protrudes from the relief hole 14. A spring 13 is sleeved on the positioning post 11. The upper end of the spring 13 is fixed on the positioning post 11, and the lower end of the spring 13 abuts against the movable plate 10 on both sides of the relief hole 14, so that the spring 13 is in a compressed state. When the clutch lever 12 is pressed downward, the movable plate 10 is lifted upward. The positioning post 11 can play a guiding role, and the relief hole 14 can limit the upward rotation angle of the movable plate 10. The movable plate 10 only needs to be slightly lifted upward to separate the helical gear 7 from the rack 4. When the clutch lever 12 is released, under the elastic force of the spring 13, the movable plate 10 is pressed tightly on the slide plate 6, so that the two are always attached, avoiding the movement of the position of the slide plate 6 caused by the upward rotation of the movable plate 10 during the normal operation of the welding device.

[0023] Continuing from the above, the structural arrangement for the clutch lever 12 to pry the movable plate 10 is as follows: The hinged end of the movable plate 10 extends outward to form two spaced-apart connecting blocks 17. Through holes are spacedly provided on the connecting blocks 17. Two fixed seats 15 are spacedly arranged on the sliding plate 6. The two fixed seats 15 are connected by a fixed shaft 16. The fixed shaft 16 is passed through one set of through holes on the two connecting blocks 17, enabling the movable plate 10 to rotate up and down along the fixed shaft 16. A rotating shaft 19 is arranged between the other set of through holes on the two connecting blocks 17. As Figure 5 shown, the clutch lever 12 is divided into a hand rocker 121 and a connecting rod 122. Among them, the connecting rod 122 is parallel to the direction of the rotating shaft 19. The hand rocker 121 is connected to the connecting rod 122 and forms an obtuse angle. A swinging block 18 is fixedly installed at one end of the connecting rod 122. The swinging block 18 can adopt a structure similar to a cam, as long as it can lift the movable plate 10 upward during rotation. In this embodiment, the swinging block 18 has a strip-shaped structure, and a through hole 182 is provided on the swinging block 18. Taking Figure 5 the direction shown as a reference, the connecting rod 122 is fixed to the upper end of the swinging block 18. The through hole 182 is located in the middle of the swinging block 18. The lower part of the swinging block 18 is set as an inclined surface 181. The swinging block 18 is installed on the rotating shaft 19 through the through hole 182, enabling the swinging block 18 to rotate.

[0024] When installing the swinging block 18, the swinging block 18 is embedded into the gap between the fixed shaft 16 and the rotating shaft 19, and the inclined surface 181 of the swinging block 18 faces the side of the movable plate 10. When the movable plate 10 is normally in close contact with the sliding plate 6, the swinging block 18 is limited by the limiting post of the fixed shaft 16. Even if the hand rocker 121 is pulled upward, the swinging block 18 cannot rotate. When the hand rocker 121 is pressed downward with force, the swinging block 18 starts to rotate, and the inclined surface 181 gradually approaches the movable plate 10. When the longest end of the swinging block 18 abuts against the bottom of the movable plate 10 and a downward pressing force is continuously applied, the movable plate 10 can be slightly lifted upward, thereby separating the spiral gear 7 from the rack 4. In this embodiment, the clutch lever 12 is not arranged outside the track 1 to prevent accidental contact with the clutch lever 12 during the operation of the operator. By arranging it inside, the use safety is higher.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
