Description

Technical Field

[0001] The invention belongs to the technical field of weld interface positioning, and in particular relates to a disperser welding weld interface positioning device. Background Art

[0002] Disperser is a kind of mixer in a broad sense. Since the use of high-speed agitators (such as disc sawtooth agitators) can form strong turbulence locally, it usually has a strong dispersing and emulsifying effect on the material. Therefore, this type of high-speed agitator is also called a disperser. Dispersers are mainly divided into lifting type dispersers and kettle dispersers. Lifting type dispersers can be divided into hydraulic lifting dispersers, electric lifting dispersers, pneumatic lifting dispersers, hand-cranked lifting dispersers, etc. according to the lifting method.

[0003] The welding device for the high-efficiency cantilever beam type pipeline annular weld described in the patent application with reference publication number CN114178757A includes two cantilever beam welding machines and two annular pipeline positioning platforms. The two cantilever beam welding machines are distributed on the left and right sides of the two annular pipeline positioning platforms, and the two annular pipeline positioning platforms are distributed on the front and back sides of the two cantilever beam welding machines. The annular pipeline positioning platform includes a fixed lower positioning seat, a support frame, a cylinder, a solenoid valve, a movable upper positioning seat and an infrared ranging sensor. The annular pipeline positioning platform is used to clamp and fix two annular pipelines. The present invention can simultaneously weld the annular interface through several welding guns, which not only improves the welding work efficiency, but also ensures the stability and reliability after welding.

[0004] In the welding operation of the disperser, a positioning clamping mechanism is usually required to perform butt clamping auxiliary operations so that the welding positions of the welding workpieces are well butted to form a complete weld. Therefore, when adjusting the butt weld, one or two workpiece positions need to be adjusted. The adjustment includes linear movement and rotation adjustment of the welding port, which requires different fixed clamping and movable clamping (limiting) effects. In addition, the disperser contains a large number of cylindrical workpieces, and the models, sizes and lengths are different. The usual clamping and positioning mechanism uses a fixed clamping force for clamping and positioning (such as the above-mentioned technical means), which is difficult to apply to the position adjustment of such workpieces in different orientations. In order to solve the above problems, a disperser welding weld interface positioning device is proposed. Summary of the invention

[0053] It should be noted that, in the existing dispersion machine processing welding operation, a positioning clamping mechanism is usually required to perform butt clamping auxiliary operations so that the welding positions of the welding workpieces are butted together to form a complete weld. Therefore, when adjusting the butt weld, it is necessary to adjust the positions of one or two workpieces. The adjustment includes linear movement and rotational adjustment of the welding mouth, which requires different fixed clamping and movable clamping (limiting) effects. In addition, the dispersion machine contains a large number of cylindrical workpieces, and the models, sizes and lengths are different. The usual clamping and positioning mechanism uses a fixed clamping force for clamping and positioning, which is difficult to apply to the position adjustment of such workpieces in different orientations.

[0054] Specifically, in this embodiment, this scheme mainly operates the platform 1, the first sliding base assembly 4, the vertical frame assembly 5, the fixed inner frame 9, the movable inner frame 6, the clamping control assembly 2, the clamping assembly 3 and the second sliding base assembly 7.

The wall is tightly fitted, so that the outer wall of the upper cylindrical workpiece to be welded by the dispersing machine has a better clamping effect, and the second hydraulic cylinder 2043 is started and controlled to push the lower exhibition column 2042, so that the lower exhibition column 2042 rotates along the short pin at the connection between the lower exhibition column 2042 and the outer exhibition frame 2041, and then the position of the airbag clamp 2044 on the lower exhibition column 2042 is adjusted, so that the outer wall of the airbag clamp 2044 is tightly fitted with the outer wall of the cylindrical workpiece to be welded, so as to achieve a better tight limiting effect with the workpiece. At this time, the airbag column and the airbag clamp 2044 on the second clamp column 2024 serve as the main clamping and limiting role, and the thick rubber tube on the first clamp column 2022 serves as an auxiliary limiting effect;

[0055] Then, the outside of the workpiece to be butt-welded with the cylindrical workpiece is placed on the tray 701 away from the welding position, and the outside of the workpiece is limited by the limiting clamping column 702, and the second slide 705 and the position of the butt-jointed workpiece on the second slide 705 are moved and adjusted, so that the welding position of the butt-jointed workpiece and the welding position of the cylindrical workpiece clamped on the clamping control component 2 and the clamping component 3 are in a vertical state, so as to facilitate the butt-jointing of the welds; start and control the use of the side drive motor 501, and drive the transmission gear 503 to rotate by using the side drive motor 501, and the outer wall of the spur plate 603 is meshed and connected with the outer wall of the transmission gear 503, so as to drive the movable frame 601 to rise and fall along the inner wall of the side slide 502, so as to adjust the use height of the clamping control component 2 and the clamping component 3 on the movable frame 601, so as to linearly move the height of the cylindrical workpiece clamped on the clamping control component 2 and the clamping component 3, so that the cylindrical workpiece is finally butt-jointed with the butt-jointed workpiece to form a weld, so as to facilitate the welding operation;

[0056] When rotation adjustment is required, the clamping assembly 3 is controlled to release the clamping state, and the second hydraulic cylinder 2043 is controlled to pull the lower exhibition column 2042, so that the lower exhibition column 2042 rotates along the short pin at the connection between the lower exhibition column 2042 and the outer exhibition frame 2041, and then the position of the air bag clamp 2044 on the lower exhibition column 2042 is adjusted, so that the outer wall of the air bag clamp 2044 is slightly away from the outer wall of the cylindrical workpiece to be welded, and the exhaust control valve is controlled to reduce the gas inside the air bag column, so that the outer wall of the air bag column on the second clamping column 2024 is loosely fitted with the outer wall of the cylindrical workpiece, so that the welding position of the workpiece can be rotated and adjusted, and the side close to the arc center plate 201 is turned outward to continue welding.
