For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] Referring to the drawings Figs. 1-3 A kind of welding positioning device of angle steel tower assembly, comprising:

[0029] An operation table 1 is provided with two guide grooves 2; a plurality of transmission rollers 3 are arranged in the guide grooves 2, and a limiting groove 4 is arranged between the two guide grooves 2; a plurality of limiting holes 5 arranged in a straight line are arranged on the operation table 1; an opening is arranged at one end of the operation table 1 and communicates with the limiting groove 4, so as to facilitate the placing or removing of the clamping assembly into or out of the limiting groove 4;

[0030] The clamping assembly is arranged in the limiting groove 4 and comprises a clamping plate one 6, a clamping plate two 7, a clamping plate three 8 and a threaded rod 9; the clamping plate one 6 is provided with a bearing in the middle, and one limiting block 10 is arranged on each side of the clamping plate one 6; the lower half of the clamping plate two 7 is provided with a threaded groove; the clamping plate three 8 is fixed on the top of the limiting block 10 on one side through a bolt; one end of the threaded rod 9 is rotatably connected with the bearing, and the other end penetrates through the threaded groove and is connected with a rotating handle 11;

[0031] The positioning plate 12 is L-shaped, and an avoiding groove 13 is arranged at the corner of the positioning plate 12; a half-threaded bolt 14 is arranged in the avoiding groove 13, and the lower end of the half-threaded bolt 14 enters the limiting hole 5 in the corresponding position and is threadedly connected with the limiting hole 5;

[0032] The guide plate 15 is fixed on the top of the operation table 1 and is located on one side close to the limiting hole 5.

[0033] In this embodiment, two sliding grooves 16 are arranged on the operation table 1, and the two sliding grooves 16 are respectively arranged on the two sides of the limiting groove 4; the limiting block 10 is arranged in the sliding groove 16 and is in sliding connection with the sliding groove 16. When the staff manually pushes the clamping assembly to move in the limiting groove 4, the two limiting blocks 10 on the clamping plate one 6 slide in the corresponding sliding grooves 16, and at the same time, the two limiting blocks 10 also play a limiting role, so as to prevent the clamping assembly clamping the transverse angle steel from deviating and affecting the subsequent welding.

[0034] In addition, a vertical baffle 17 is arranged at the middle position of the bottom of the clamping plate three 8, and the lower end of the baffle 17 enters the sliding groove 16. The baffle 17 can play a limiting role on the clamping plate three 8, and when the bolt on the limiting block 10 is tightened, the clamping plate three 8 can be vertically moved downward to clamp the horizontal plate of the transverse angle steel. The side surface of the horizontal rod of the transverse angle steel abuts against the baffle 17, and the clamping plate two 7 abuts against the vertical plate of the transverse angle steel, so that the transverse angle steel can be clamped stably and will not shake during the moving welding process.

[0035] On the other hand, two sliding grooves 16 are provided with a rack 18 below one side plate of the limiting groove 4; the upper surface of the clamping plate 6 is provided with a rack 19 on both sides, which cooperates with the corresponding position of the rack 18. When the clamping assembly moves the transverse angle steel to the welding positioning point, the worker rotates the bolt on the limiting block 10, at this time the clamping plate 6 slowly moves upward, so that the rack 19 cooperates with the corresponding position of the rack 18, and the clamping plate 6 is limited, so that the relative position of the clamping plate 6 and the side plate of the sliding groove 16 no longer changes. Thus, the clamped transverse angle steel remains in a fixed state, facilitating subsequent welding fixation.

[0036] In the actual welding process, the worker first places the longitudinal angle steel on the transmission roller 3 on one side of the guide plate 15 on the operation table 1, so that the vertical plate side of the longitudinal angle steel is in contact with the side of the guide plate 15; then moves the longitudinal angle steel along the guide groove 2 to the positioning plate 12, until the front end of the longitudinal angle steel is in contact with the inner side of the right angle surface of the positioning plate 12, at this time the position of the longitudinal angle steel no longer changes. The corner of the positioning plate 12 is fixed in the corresponding limiting hole 5 by the half-threaded bolt 14, and during the movement of the longitudinal angle steel, the positioning plate 12, which does not limit the longitudinal angle steel, rotates the inner side of the right angle surface to the side away from the longitudinal angle steel, facilitating the passage of the longitudinal angle steel.

[0037] When the longitudinal angle steel no longer moves, the transverse angle steel is placed on the operation table 1, so that the side of the horizontal plate is in contact with the stop plate 17 at the bottom of the clamping plate 3, and then the worker rotates the rotating handle 11 at one end of the threaded rod 9, which drives the clamping plate 2 to move towards the clamping plate 1, until the clamping plate 2 is in contact with the vertical plate side of the transverse angle steel, at this time the transverse angle steel is clamped by the clamping assembly.

[0038] After the above steps are completed, the worker can manually push the clamping assembly to move the transverse angle steel to the welding positioning point; one end of the transverse angle steel is placed on the horizontal plate of the longitudinal angle steel, and the other end is placed on the transmission roller 3 away from the guide plate 15, which facilitates the movement of the transverse angle steel; when the transverse angle steel reaches the welding positioning point, the worker rotates the bolt on the limiting block 10, so that the rack 19 cooperates with the corresponding position of the rack 18, and the clamping plate 6 is limited, so that the position of the entire clamping assembly and the transverse angle steel no longer changes. Finally, the worker uses the welding equipment to complete the welding. It should be noted that the side of the transverse angle steel close to the longitudinal angle steel needs to be cut first, so that the transverse angle steel and the longitudinal angle steel can be welded to keep the surface flat and meet the construction requirements.

[0039] The welding positioning device of the angle steel tower assembly is convenient for the movement of the transverse angle steel and the longitudinal angle steel, the transverse angle steel is clamped and limited by the clamping assembly, a plurality of positioning plates 12 are arranged to cooperate with the longitudinal angle steel, the welding positioning point can be quickly determined, the welding efficiency is improved, the device is very practical, and has a good market application prospect.

[0040] The foregoing description of the specific exemplary embodiments of the present application is for illustrative and exemplification purposes. These descriptions are not intended to limit the application to the precise forms disclosed, and obviously many changes and modifications can be made therefrom by those of ordinary skill in the art in light of the foregoing teachings.
