Description

Technical Field

[0001] The utility model relates to the field of welding devices, in particular to an automatic stud welding platform for plate-type heat exchange equipment. Background Art

[0002] In the design process of plate heat exchange equipment, two methods are usually used to design the mutual support between the plates to meet the spatial stability of the heat exchange flow channel; one is stamping, and the other is to add positioning spacer studs on the surface of the plate.

[0003] Stamping is relatively simple for smaller heat exchanger plates, but for larger plates, the processing capacity of the stamping equipment will increase. In order to ensure that the thickness reduction after stamping still meets the design thickness requirements, the thickness of the heat exchanger plate is often increased, which in turn increases the design and manufacturing cost of the equipment. Although the welding stud method increases the cost of the studs at first glance, all heat exchanger plates can meet the minimum design requirements. The low cost of the screws and their universal applicability make the overall planning cost much lower than the stamping method. However, the stud welding equipment currently on the market cannot achieve fully automated welding for different plate types. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 The utility model is described in further detail.

[0024] Example 1:

[0025] This embodiment provides a stud automatic welding platform for plate heat exchange equipment, comprising a welding platform 1, an equipment platform 2 movably disposed on the welding platform 1, and a welding seat 3 disposed on the equipment platform 2.

[0026] like Figure 1-3 The welding platform 1 is provided with mutually parallel first guide rail groups 12 on both sides. The inner side of the first guide rail group 12 is provided with a first guide rib 13 parallel to the guide rail. A base 21 is provided on the first guide rail group 12. The bottom of the base 21 of the equipment platform 2 has a clip that is clamped to the first guide rail group 12 from both sides. A through hole is provided at one end of the base 21, and a first motor 212 is installed in the through hole. The rotating shaft of the first motor 212 passes through the through hole and is connected to a first roller 213. The first roller 213 is in close contact with the guide rib 13. When the first motor 212 drives the first roller 213 to rotate, the friction between the first roller 213 and the side of the guide rib 13 drives the base 21 to move. Both bases 21 are provided with a first motor 212, and the stepping distance of the two first motors 212 is synchronized.

[0027] like Figure 4 As shown, the front side of the equipment support shaft 22 of the equipment platform 2 is provided with a second guide rail group 221, and the second guide rib 222 is arranged above the equipment support shaft 22. The welding seat 3 is connected to the second guide rail group 221 through a snap-fit ​​connection. A second motor 223 and a second roller 224 are provided above the welding seat 3. The second motor 223 drives the second roller 224 to cooperate with the second guide rib 222 to realize the movement of the welding seat 3 along the direction of the second guide rib 222.

[0028] like Figure 5As shown, a welding gun connector 32 is fixed on the welding seat 3, and the welding gun 31 is fixed on the welding gun connector 32 with an adjustable angle. At the same time, a telescopic rod 321 and a third motor 322 are provided on the welding gun connector 32. The welding gun 31 is movably connected to the welding gun connector 32 through a buckle and a limiting rib, and the welding gun 31 is also connected to the bottom of the telescopic rod 321 through a fixing member. When the third motor 322 drives the telescopic rod 321 to extend and retract, the bottom of the telescopic rod drives the welding gun 31 to move up and down.

[0029] In this embodiment, a power supply module 225 is further provided on the equipment support shaft 22 for supplying power to the first motor 212 , the second motor 223 and the third motor 322 .

[0030] The welding platform 1 in this embodiment is further provided with a control cabinet 14 for controlling the motors.

[0031] The welding platform 1 in this embodiment is provided with a fixing device for fixing heat exchange plates 11 of different types. The fixing device is not shown in the drawings, and is specifically a clamping device parallel to the first guide rail group 12 with adjustable position.

[0032] When this embodiment is in use, the raw material plates are transported to the plate welding platform by a overhead crane, the equipment intelligent control cabinet is opened, and all equipment is powered on. The stud nails are sent to the welding gun by the feeding and shaking disk, and the first motor and the second motor send the welding gun to the upper surface of the raw material plate. The welding gun stores energy and welds. After welding is completed, the third motor of the welding gun sends the welding gun position upward to the starting point, and at the same time, the first motor sends the welding gun to the next point. The feeding and shaking disk sends the nails to the welding gun, and the third motor sends the welding gun downward to the raw material plate. The welding gun stores energy and completes welding. The third motor sends the welding gun upward to the starting point, and the first motor sends the welding gun to the next point. This cycle repeats until all the axial stud nails are welded. When the welding of a row of axial stud nails is completed, the first motor resets the welding gun, and the second motor moves the welding gun to the next axis. The above steps are repeated until all welding work is completed.

[0033] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
