The preferred embodiments of the present invention are given in the drawings of the specification. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] In order to solve the above-mentioned shortcomings, the technical solution adopted by the present invention is:

[0029] In one embodiment, a single- and double-station adjustable cantilever welding machine bracket comprises a column, a tensioning mechanism, a beam mechanism and a welding mechanism; the column is symmetrically equipped with the tensioning mechanism, the beam mechanism and the welding mechanism; the bottom of the column is fixed to the ground; the top of the column is equipped with the tensioning mechanism; one end of the beam mechanism is installed on the column below the tensioning mechanism; the other end of the beam mechanism is equipped with the welding mechanism; the other end of the beam mechanism is connected to the tensioning mechanism; the beam mechanism and the tensioning mechanism both have a rotation function.

[0030] The above-mentioned single- and double-station adjustable cantilever welding machine bracket includes a column, a tensioning mechanism, a beam mechanism and a welding mechanism, and the rotation angle of the beam mechanism is 0 to 180 degrees. Compared with the prior art, the present invention can increase or decrease the length of the beam as needed to meet the requirements of different working radiuses; the present invention eliminates safety hazards and optimizes the welding machine working conditions by internalizing the power cord and fixing the hose and welding gun to the bracket; the present invention greatly improves the work efficiency through a column and a double-side station design; and the welding bracket has a simple structure, low manufacturing cost, long service life, and is widely applicable to welding operations.

[0031] The mechanical workbench applied to high-frequency rotation operations will be described below in conjunction with specific embodiments to further understand the inventive concept of the mechanical workbench applied to high-frequency rotation operations.

[0032] See also Figure 1 and Figure 2The single- and double-station adjustable cantilever welding machine bracket comprises a column 100, a tensioning mechanism 200, a beam mechanism 300 and a welding mechanism 400; the column 100 is symmetrically mounted with the tensioning mechanism 200, the beam mechanism 300 and the welding mechanism 400; the bottom of the column 100 is fixed to the ground by an anchor bolt 110; the top of the column 100 is mounted with the tensioning mechanism 200; one end of the beam mechanism 300 is mounted on the The column 100 is below the tensioning mechanism 200; the welding mechanism 400 is installed on the other end of the beam mechanism 300; the other end of the beam mechanism 300 is connected to the tensioning mechanism 200; the column 100 and the beam 320 are both hollow structures, and the present invention carries out built-in processing of the welding machine and the wire feeder power cord 470, that is, the welding machine and the wire feeder power cord 470 are successively passed through the hollow structures of the column 100 and the beam 320. The material or size of the column 100 can be flexibly selected according to specific working conditions. The material of the column 100 can be steel (H-steel or channel steel, etc.), which not only reduces the weight of the column 100 but also increases the rigidity. At the same time, an internal channel is provided for the welding machine and wire feeder power cord 470, and there is no relative movement between the welding machine and wire feeder power cord 470 and the column 100, eliminating the safety hazard caused by the wear and leakage of the insulation of the welding machine and wire feeder power cord 470.

[0033] In one embodiment, see Figure 2 The angle between the tensioning mechanism (200) and the beam mechanism (300) of the present invention is 8 degrees, and the angle between the tensioning mechanism (200) and the beam mechanism (300) can also be 5 degrees to 10 degrees. On the one hand, a suitable angle is beneficial to the tensioning effect of the tensioning mechanism (200) on the beam mechanism (300), so that the tension borne by the tensioning mechanism (200) is reduced, which is beneficial to the service life of the tensioning mechanism (200) and the beam mechanism (300); on the other hand, a suitable angle is beneficial to the overall working performance of the welding machine bracket of the present invention, and is beneficial to the overall service life of the welding machine bracket.

[0034] In one embodiment, see Figure 1 and Figure 3The beam mechanism 300 includes a vertical rotating roller 310, a beam 320, a left adjustment plate 330, a right adjustment plate 340, a fixed pin 350, an adjustment pin 360 and a connecting pin 370; the vertical rotating roller 310 is fixedly connected to the column 100; one end of the beam 320 is connected to the column 100 through the vertical rotating roller 310; the other end of the beam 320 is installed with the connecting pin 370; the left adjustment plate 330 and the right adjustment plate 340 are connected to the beam 320 through the fixed pin 350 and the adjustment pin 360.

[0035] In one embodiment, see Figure 1 The tensioning mechanism 200 includes a connecting seat 210, a hinge pin 220, a lead screw 230, a canted spring 240 and a canted rod 250; the connecting seat 210 is fixedly connected to the column 100; one end of the lead screw 230 is connected to the connecting seat 210 through the hinge pin 220; the other end of the lead screw 230 is connected to the canted spring 240; the canted rod 250 is connected to the cross beam 320 through the connecting pin 370. The device of the present invention can adjust the screw-in length of the lead screw 230 inside the hinge pin 220 by applying torque to the lead screw 230, thereby controlling the effective working length of the lead screw 230, so as to adjust the overall length of the tensioning mechanism 200 and indirectly adjust the height of the wire feeder 430, so that the device of the present invention is suitable for different working conditions and has more flexibility in operation.

[0036] In one embodiment, the welding mechanism 400 includes a welding wire wheel 410, a welding wire 420, a wire feeder 430, a wire feeder and welding gun connecting hose 440, a welding gun 450, a welding machine 460 and a welding machine and wire feeder power cord 470; the welding wire wheel 410 is installed at the end of the right adjustment plate 340; the wire feeder 430 is fixed to the extension seat of the beam 320 with bolts; the welding machine 460 and the wire feeder 430 are connected through the welding machine and wire feeder power cord 470; the wire feeder 430 is connected to the welding gun 450 through the wire feeder and welding gun connecting hose 440, and the welding gun 450 can be moved appropriately according to the welding position of the workpiece. During operation, the wire feeder 430 consumes the welding wire 420 as the welding gun 450 works, and the wire feeder 430 rotates and drives the welding wire wheel 410 to rotate. When the welding wire 420 in the welding wire wheel 410 is consumed, a new welding wire wheel 410 is replaced.

[0037] In one embodiment, see Figure 2, the column 100 is designed for single- and double-station operation, and can be flexibly selected according to specific working conditions. The beam mechanism 300 in the device of the present invention is rotated by the vertical rotating roller 310, and the rotation angle is 0 to 180 degrees; the tensioning mechanism 200 is rotated by the hinge pin 220, and the rotation angle is 0 to 180 degrees. The device of the present invention can effectively achieve a 360-degree working range through the rotation of the beam mechanism 300 and the tensioning mechanism 200, greatly improving the work efficiency. Specifically, the beam 320 and the wire feeder 430 can rotate freely with the column 100 as the center of the circle, and can operate at any position in this area, greatly reducing the labor intensity of the operator. At the same time, if there is a height requirement for the weldment operation area, the operator can flexibly move the welding gun 450 to perform the corresponding welding operation, so that the device of the present invention has a wider range of application, convenient operation and high efficiency.

[0038] In one embodiment, see Figure 4 A thrust ball bearing is installed at the upper end of the vertical rotating roller 310. The thrust ball bearing is a point contact bearing, which mainly bears radial loads and can also bear certain axial loads. It is commonly used in low-speed rotating mechanisms; a deep groove ball bearing is installed at the lower end of the vertical rotating roller, which can withstand the combined load of radial and axial forces acting simultaneously.

[0039] In one embodiment, the existing welding support is usually composed of a welding machine 460, a welding machine and a wire feeder power cord 470, a welding wire wheel 430, a wire feeder 430, a wire feeder and a welding gun connecting hose 440, and a welding gun 450. During the welding operation, all of the above components are directly placed on the ground, which makes on-site 6S management difficult and poses great safety hazards. In particular, when working at equal heights, the wire feeder and the welding gun connecting hose 440 and the welding gun 450 need to be moved as a whole. As a result, the prior art has problems such as too high labor intensity, low efficiency, small adjustable stroke, easy deformation of the spring, and poor adjustability. The purpose of adding a welding machine support to the device of the present invention is to solve the above problems in actual production. The specific operation process of the single- and double-station adjustable cantilever welding machine support of the present invention is as follows:

[0040] During operation, the power supply of the welding machine 460 is started, the voltage, current and gas pressure are adjusted, and the gas and current are transmitted to the wire feeder 430 through the welding machine and the wire feeder power line 470, and the wire feeder 430 starts to work. When the welding operation starts, the welding wire 420 begins to be consumed. As the welding wire 420 is consumed, the device of the present invention generates a pulling force, so that the welding wire wheel 410 rotates, and the welding wire 420 is continuously provided to the welding gun 450. When the welding wire 420 in the welding wire wheel 410 is consumed, a new welding wire wheel 410 is replaced.

[0041] The single- and double-station adjustable cantilever welding machine support of the present invention works as follows: Since the spatial position of the welding machine workpiece 480 is uncertain, the accessibility of the welding gun 450 within the equal height working radius can be changed by rotating the tensioning mechanism 200 and the beam mechanism 300 at the same time as the position of the target weldment is different; the tensioning mechanism 200 and the beam mechanism 300 can also be moved up and down at the same time according to the working condition requirements, thereby changing the height of the wire feeder 430 from the ground, that is, the position of the wire feeder 430, and the scalability of the inclined tension spring 240 can effectively achieve the purpose of changing the working range in the height direction. The double station is the mirror image principle of the single station, which doubles the working range of the single station.

[0042] The actual working process is that the welding machine bracket of the present invention changes in coordination with the welding machine operation. The batch use of the welding machine bracket of the present invention has obvious effects on solving the 6S management difficulties at the welding machine operation site, reducing safety risks, and reducing the labor intensity of operators.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
