DETAILED DESCRIPTION
[0022] The technical solutions will be further described below in combination with specific embodiments. It should be noted that the words such as up, down, left, right, etc. in this article are only for the position of the shown structure in the corresponding drawings. The serial numbers of the components in this article, such as first, second, etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. Unless otherwise specified, the connection and coupling in this application include direct and indirect connection.
[0023] Specific reference Figure 1 The welding device for gas cylinder processing shown includes a chassis 1, a lifting column 3, a crossbeam 4, and a welding gun 7. The chassis 1 is spliced and welded by horizontal and vertical staggered square tubes. Two lifting columns 3 are arranged at the two ends of the chassis 1, and a crossbeam 4 is arranged between the two lifting columns 3. The crossbeam 4 specifically includes a driving mechanism 41, a lead screw 42, and a lead screw nut 43. The lead screw nut 43 is installed on the lead screw 42, and the two ends of the lead screw 42 are correspondingly arranged on the two lifting columns 3. In this embodiment, the driving mechanism 41 uses a transmission structure of a motor and a gear. The motor and the lead screw 42 are provided with gears that mesh with each other. The bottom of the lead screw nut 43 is also provided with a rotating mechanism 6. The welding gun 7 is arranged on the rotating mechanism 6. The position adjustment in the height direction of the welding gun 7 and the longitudinal movement can be realized through the above-mentioned lifting column 3 and crossbeam 4. When different radius gas cylinders need to be welded, the height direction can be adapted through the lifting column 3, and the welding gun 7 can be moved in the longitudinal length direction through the crossbeam 4, so that the flexible adjustment of the welding gun 7 is realized.
[0024] In addition, as Figure 2 shown, the rotating mechanism 6 specifically includes a frame, a vertical shaft 61, a micro motor 62, and two gears 63. The frame is fixedly arranged at the bottom of the lead screw nut 43. The micro motor 62 is fixedly arranged on the frame through a motor frame. The vertical shaft 61 is connected with the frame in a rotating manner. The micro motor 62 and the vertical shaft 61 are respectively provided with a gear 63. The two gears 63 mesh with each other. The welding gun 7 is fixedly arranged at one end of the vertical shaft 61 through a clamp. Through the setting of the rotating mechanism, the welding gun 7 can be rotated at any angle in the plane, so that the welding point position of the welding gun 7 can be accurately adjusted.
[0025] As Figure 4 shown, the lifting column 3 comprises a fixed part 31 and a cylinder II 32, wherein the lower end of the fixed part 31 is arranged on the chassis 1, the upper end is connected with the cylinder II 32, the cylinder II 32 is arranged vertically, the telescopic rod of the cylinder II 32 is vertically downward and connected with the end of the cross beam 4. The position adjustment of the cross beam 4 in the height direction is realized through the cylinder II 32.
[0026] In addition, the device further comprises an infrared level meter 8, which is arranged on one of the lifting columns 3. When the infrared level meter is started, a straight line is indicated on the bottle body. By rotating the bottle body to make the longitudinal joint coincide with the straight line, the longitudinal joint can be quickly coincided with the welding point by adjusting the position of the welding point, thereby improving the welding speed.
[0027] The device adjusts the bottle body of the gas cylinder by using the limiting part 2, which specifically comprises a fixed wheel row 21 and a movable wheel row 22.
[0028] The fixed wheel row 21 comprises a horizontal shaft 211 and a plurality of rollers I 213 arranged at intervals on the horizontal shaft 211. The arrangement direction of the horizontal shaft 211 is consistent with the welding direction of the longitudinal joint, that is, the horizontal shaft 211 is parallel to the cross beam 4. The two ends of the horizontal shaft 211 are installed on the upper end of the chassis 1 through the lug plate. In a preferred embodiment, the rollers I 213 are coaxial with the horizontal shaft 211 and are connected in a fixed manner. One end of the horizontal shaft 211 is in transmission connection with the steering engine 212.
[0029] The movable wheel row 22 comprises a plurality of movable arms 221 arranged at intervals. The middle parts of the movable arms 221 are respectively hinged to the chassis 1 through the pin shaft. The upper ends of the movable arms 221 are respectively provided with rollers II 223, and the lower ends are jointly provided with a horizontal rod 222. The horizontal rod 222 is hinged to the telescopic end of the cylinder I 224. The tail of the shell of the cylinder I 224 is hinged to the chassis 1. It should be noted that the rollers II 223 and the rollers I 213 are arranged in a staggered manner. The lifting control of the rollers I 213 is realized by the extension and retraction of the telescopic end of the cylinder I 224, so that the gas cylinder can be clamped or released. When the position of the longitudinal joint needs to be adjusted, the rotation of the rollers I 213 is driven by the steering engine 212, so that the rotation of the bottle body of the gas cylinder can be realized, thereby adjusting the longitudinal joint to the best welding position.
[0030] The above embodiments only express the preferred embodiments of the present application, which are described in detail and specifically, but cannot be understood as the limitation of the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications, improvements and substitutions can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
