Description

Technical Field

[0001] The utility model relates to a wire feeding suspension device for a welding machine, in particular to a wire feeding suspension device for an electric gantry welding machine. Background Art

[0002] During the aluminum welding process, when welding larger objects, due to the large volume of the welded object, the welding machine needs to be constantly moved to a suitable welding position. When moving the welding machine, the welding machine cable also needs to be constantly moved, which is time-consuming and laborious, and the workload is large. It requires multiple people to cooperate, and the production efficiency is not high. Moreover, during the movement of the cable, it is easy to break, increasing the loss of the welding machine cable and the company's cost expenditure. In view of the above problems, we invented a wire feeding suspension device for a welding machine with the application number 202020677658.7. During the working process, we found that the above device can only weld in a circle at a fixed position. The wire feeding suspension device of the welding machine can only rotate in a circle and cannot move back and forth horizontally. For areas beyond the length of the telescopic frame itself, the wire feeding suspension device of the welding machine still needs to be manually moved and fixed, and the back-and-forth movement is troublesome, reducing the working efficiency. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: in the prior art, it is necessary to manually move the position of the wire feeding suspension device of the welding machine to weld at a farther position, and the back-and-forth movement is troublesome, resulting in low working efficiency.

[0004] To solve the above technical problem, a technical solution provided by the utility model is:

[0005] An electric gantry welding machine wire feeding suspension device, including a gantry and a wire feeding suspension device of the welding machine. The wire feeding suspension device of the welding machine includes a rolling shaft and a rotating shaft. A suspension substrate is arranged outside the rotating shaft. An extendable or retractable telescopic frame is arranged on the suspension substrate. The rolling shaft is arranged inside the rotating shaft. A bearing is arranged between the rolling shaft and the rotating shaft to facilitate the circumferential rotation between the rolling shaft and the rotating shaft.

[0006] A U-shaped connecting plate is arranged on the upper end surface of the rolling shaft. A connecting shaft is arranged on the U-shaped connecting plate. A moving pulley and a gear are arranged on the connecting shaft. The moving pulley is arranged on the gantry and can move on the gantry. The connecting shaft passes through the U-shaped connecting plate and is connected to a motor. The motor is arranged on a motor fixing plate. The side of the motor fixing plate is connected to the outside of the rolling shaft. When the motor rotates, it drives the moving pulley to rotate. When the moving pulley rotates, it drives the U-shaped connecting plate to move on the gantry, and further drives the wire feeding suspension device of the welding machine to move on the gantry, realizing the movement of the wire feeding suspension device of the welding machine in the horizontal direction in terms of length and distance position.

[0007] Furthermore, the gantry includes columns and a cross beam. One column is respectively arranged at each of the left and right ends of the cross beam. The lower end faces of the two columns are fixed on the ground. The cross beam is an I-beam. The moving pulley includes two upper moving pulleys and two lower moving pulleys. Upper guide rails are arranged on the upper end faces of the two side edges at the lower end of the I-beam, and lower guide rails corresponding to the upper guide rails are arranged on the lower end faces. The two upper moving pulleys are respectively arranged on the two upper guide rails, and the two lower moving pulleys are respectively arranged on the two lower guide rails. The upper guide rails and the lower guide rails can guide the traveling directions of the upper moving pulleys and the lower moving pulleys to prevent deviation during the moving process.

[0008] Furthermore, the U-shaped connecting plate includes a left side plate, a right side plate and a lower side plate. The left side plate and the right side plate are respectively arranged at the left and right ends of the lower side plate.

[0009] Furthermore, adjusting holes and lower connecting holes distributed up and down are respectively arranged on the left side plate and the right side plate. A sliding plate capable of sliding up and down in the corresponding adjusting hole is arranged in each adjusting hole. By moving the position of the sliding plate, the distance between the sliding plate and the lower connecting hole can be adjusted.

[0010] Furthermore, through holes connected to the corresponding adjusting holes are respectively arranged on the upper end faces of the left side plate and the right side plate. Bolts are respectively arranged in the two through holes. The lower end face of the bolt is connected to the upper end face of the corresponding sliding plate. The bolt drives the sliding plate to move up and down in the adjusting hole. Nuts for limiting and preventing loosening are respectively arranged on the bolts above the left side plate or the right side plate and in the corresponding adjusting holes to fix the positions of the bolts with the nuts.

[0011] Furthermore, the connecting shaft includes two short connecting shafts and one long connecting shaft.

[0012] Furthermore, upper connecting holes are arranged on the two sliding plates. Upper bearings corresponding to the upper connecting holes are arranged in the two upper connecting holes. A short connecting shaft is arranged in each upper bearing. The axis of the short connecting shaft and the center of the corresponding upper moving pulley are on the same center line. One end of each short connecting shaft far away from the upper bearing is connected to the corresponding upper moving pulley. Upper gears are respectively arranged at the positions between the two side end faces at the lower end of the I-beam and the corresponding upper connecting holes on each short connecting shaft.

[0013] Further, a lower bearing is respectively arranged in each of the two lower connecting holes. The axes of the two lower bearings and the centers of the two lower moving pulleys are on the same horizontal plane. One end of the long connecting shaft is connected to the rotating end of the motor, and the other end sequentially passes through one of the lower bearings and the two lower moving pulleys and then is connected to the other lower bearing. Lower gears are arranged at positions corresponding to the upper gears on the long connecting shaft. The upper gears and the lower gears corresponding up and down are meshed and connected. When the motor rotates, the long connecting shaft rotates, thereby driving the two lower gears and the two lower moving pulleys on the long connecting shaft to rotate. At the same time, the two upper gears are driven to rotate through meshing. When the two upper gears rotate, the corresponding two upper moving pulleys are driven to rotate, realizing four-wheel linkage, thereby driving the welding wire feeding suspension device to move on the cross beam. Using electric power to drive the welding wire feeding suspension device to move on the cross beam can save time and effort, and at the same time, can expand the working range of the welding wire feeding suspension device, eliminating the need to manually move the welding wire feeding suspension device and improving the product production efficiency.

[0014] By adjusting the distance between the sliding plate and the lower connecting hole, the distance between the upper moving pulley and the lower moving pulley can be further adjusted, so that the upper moving pulley and the lower moving pulley can be clamped on the I-beam, and it can be applicable to I-beams with different thicknesses, with a wide application range.

[0015] Further, guide rods with buckles are evenly distributed on the upper part of the middle end of the I-beam. The other end of the buckle is connected to a guide groove with an opening on the lower end face. The length of the guide groove matches the length of the I-beam. Guide wheels matching the number of the guide rods are arranged inside the guide groove.

[0016] Further, connection lines that are easy to bend and have the same length are arranged between every two of the guide wheels, which is convenient for limiting the distance between adjacent two guide wheels. One end of the power connection line is connected to the motor, and the other end passes through all the guide wheels and then is connected to the power supply. The power connection line is fixedly connected to each contact with the guide wheels by fixing wires, such as binding straps. The length of the power connection line between every two of the guide wheels is greater than the length of the connection line between the corresponding two of the guide wheels, preventing the power connection line from generating tension during the stretching process. Tension is likely to damage the power connection line and can shorten the service life of the power connection line.

[0017] Further, auxiliary plates are arranged at the joints of the left side plate and the lower side plate and the right side plate and the lower side plate inside the U-shaped connecting plate, which can increase the strength of the U-shaped connecting plate.

[0018] Further, stoppers are arranged at both ends of the I-beam to prevent the welding machine suspension device from falling off when sliding.

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

[0020] 1. In the present utility model, the wire feeding suspension device of the welding machine is arranged on the gantry. By driving the moving pulley with a motor to move and using the cross beam on the gantry as the moving track of the wire feeding suspension device of the welding machine, not only can the working area of the wire feeding suspension device of the welding machine be increased, without the need to frequently move the wire feeding suspension device of the welding machine, but also labor can be saved. While saving time and effort, the production efficiency of products can also be improved.

[0021] 2. In the present utility model, by adjusting the distance between the sliding plate and the lower connection hole, the distance between the upper moving pulley and the lower moving pulley can be adjusted accordingly, so as to clamp the upper moving pulley and the lower moving pulley on the I-beam, and it can be applicable to I-beams of different thicknesses, with a wide range of applications.
