Description

Technical Field

[0001] The utility model relates to a metal plate welding workbench. Background Art

[0002] Metal sheet welding is a common processing method. The common fixing method is to erect the metal sheet on the ground, build a corresponding bracket on the ground, and then weld it. This welding method has the following problems:

[0003] First, it is difficult to adjust the welding angle of metal sheets and the accuracy is poor.

[0004] Second, the placement stability of metal plates is poor. In the early stage of welding, when there are fewer welds, the shaking of metal plates will cause desoldering, causing trouble for the welding work.

[0005] Based on the above problems, we designed a metal sheet welding workbench which can realize the rapid fixation of metal sheets. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a metal plate welding workbench which can realize the rapid fixation of the metal plate.

[0007] The utility model is realized by the following technical solutions:

[0008] A metal plate welding workbench comprises a table, a plurality of brackets are arranged in an annular manner at the bottom of the table, under the action of the brackets, the table is separated from the ground, the table is circular, a groove is arranged on the plate surface of the table, the groove is located on the diameter line of the table, a screw is rotatably arranged in the groove, one end of the screw extends to the outside of the table, a frame plate is installed on the outside of the table, a first servo motor driving the screw to rotate is installed on the frame plate, an axial hole is arranged at the axis center of the table, a rotating shaft is rotatably installed in the axial hole, a bearing is matched between the rotating shaft and the axial hole, A servo reduction motor is installed at the bottom of the table, and the servo reduction motor is connected to the rotating shaft. A rotating arm is arranged at the upper end of the rotating shaft, and a first groove is arranged at the top of the rotating arm. The first groove is located on the diameter line of the table, and a first screw is rotatably arranged in the first groove. A first frame plate is installed at the outer end of the rotating arm, and a second servo motor for driving the first screw to rotate is installed on the first frame plate; sliding components are provided on the screw and the first screw, and an adsorption device is provided through the sliding component, and the welded metal sheet is fixed by negative pressure adsorption of the adsorption device.

[0009] Preferably, the sliding member includes a T-shaped slider, a portion of which is fitted into the groove and the first groove and slides along the groove and the first groove, a threaded hole for matching the screw rod and the first screw rod is provided on the side of the slider, a height-adjustable telescopic sleeve is installed on the top of the slider, and the adsorption device is fixed by the telescopic sleeve.

[0010] Preferably, the adsorption device includes a metal suction cup fixed to the side of the telescopic sleeve, and the outer side of the metal suction cup is connected to a high-pressure air pipe. The adsorption device also includes a vacuum pump installed at the bottom of the platform, and the suction end of the vacuum pump is connected to the high-pressure air pipe.

[0011] Preferably, an annular sealing ring is provided at the opening of the metal suction cup, and the metal sheet to be welded is contacted through the sealing ring.

[0012] Preferably, a stop bolt is screwed into the top of the first frame plate, and the stop bolt is screwed down and abuts against the table plate, and the position of the rotating arm is locked at this time.

[0013] Preferably, the high pressure air pipe has a spiral portion.

[0014] It also includes a controller, through which the servo motor, the first servo motor, the reduction servo motor and the vacuum pump are connected and driven.

[0015] When in use, the metal sheet to be welded is placed on the position of the metal suction cup, and then the corresponding vacuum pump is started. The vacuum pump generates negative pressure on the inner side of the metal suction cup to adsorb and fix the metal sheet. Then the position of the rotating arm is adjusted, and the other sheet to be welded is fixed by negative pressure adsorption. At this time, a weld is formed between the two plates and welding can be carried out.

[0016] After welding is completed, the vacuum pump is turned off, the negative pressure disappears, and the metal sheet can be removed.

[0017] When placing the metal sheet, the bottom of the metal sheet needs to be at a certain height from the table to allow the bottom of the metal sheet to be separated from the slider and avoid interfering with the rotation of the rotating arm.

[0018] When fixing the metal sheet, you can use the pad. When in use, place the pad directly on the table, and the bottom of the metal sheet is supported by the pad to reduce the difficulty of installation.

[0019] The beneficial effects of the utility model are:

[0020] Advantage 1: This device does not need to be clamped by a fixture, which avoids affecting the welding work after clamping, and also saves the fixture installation step, shortening the preparation time.

[0021] The second advantage is that fixation is more reliable and faster through negative pressure adsorption.

[0022] Advantage three: the position of the rotating arm can be adjusted according to the welding angle requirements, so that a stable angle is formed between the two metal plates to be welded, and the angle is relatively precise.

[0023] Advantage four: the device has a simple structure, low cost and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
