Description

Technical Field

[0001] The invention relates to a welding device, in particular to a sports equipment welding device applied in the field of sports equipment production. Background Art

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure; there are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] Sports equipment (also a type of sports equipment) is a general term for various equipment, gear and supplies used in competitive sports competitions and fitness exercises. In the production and processing of sports equipment, welding equipment is needed to weld the various parts.

[0004] The existing sports equipment welding device includes a welding platform and a welding gun located above the welding platform. Telescopic clamps and positioning fixtures are provided at both ends of the welding platform. The telescopic clamps are used to adjust the distance between the positioning fixture and the workpiece, and the positioning fixtures are used to clamp and fix workpieces of different shapes. However, this welding device uses the same set of fixtures, and the clamping firmness of the plate-shaped workpiece and the rod-shaped workpiece will be different, resulting in poor applicability.

[0005] To solve the above problems, the specification of Chinese patent CN116727988B discloses a sports equipment welding device, which belongs to the technical field of welding devices. The sports equipment welding device provided by the present invention includes a welding platform and a welding gun located above the welding platform, and also includes a mounting frame, a translation mechanism, a rod clamping mechanism, a plate positioning mechanism and a conversion assembly; there are two mounting frames and they are respectively located at the two ends of the welding platform; the translation mechanism is installed on the welding platform and is used to drive the two mounting frames to move closer to or away from each other; the rod clamping mechanism is used to clamp and fix the rod; the plate positioning mechanism is used to position and fix the plate; the conversion assembly is used to drive the rod clamping mechanism or the plate positioning mechanism to rotate to a working position for fixing the workpiece. The sports equipment welding device can change the position of the rod clamping mechanism and the plate positioning mechanism at any time through the conversion assembly, and can realize welding work between the same rods, between the same plates, and between rods and plates, thereby improving the applicability of the welding device.

[0006] Most existing welding devices use linear motion or circular motion to perform welding during welding, but this welding method is only suitable for welding linear welds or circular welds. Although it can also weld multi-segment linear welds with changing angles and arc welds with multiple arcs (especially when there are recessed or protruding parts in the welds), welding needs to be performed in sections. The weld joints after multi-segment welding are prone to over-welding or cold welding, resulting in weak points in the welds and insufficient stability. At the same time, due to the position difference in the protruding or recessed parts of the multi-segment welds, the front end of the welding gun needs to be retracted or extended to fit the weld, resulting in insufficient stability in the contact between the welding gun and the device to be welded during the welding process. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to provide a sports equipment welding device that can provide a certain telescopic compensation for the welding gun, so that when the welding gun encounters a telescopic or concave weld, the contact with the device to be welded is more stable, and at the same time can avoid the existence of weak points in the weld connection caused by multi-stage welding.

[0012] A driving structure for driving the angle compensation structure to move is also installed in the mounting block. The driving structure drives the welding gun to swing at multiple angles through the angle compensation structure.

[0013] In the above-mentioned sports equipment welding device, a telescopic compensation structure is used to provide telescopic compensation for the welding gun, so that the welding gun can be telescoped at the lower end of the fixed plate, thereby performing adaptive welding on the welds of the protruding part or the concave part of the device to be welded, so that the contact between the welding gun and the device is always stable during the welding process, thereby ensuring the welding quality; at the same time, the angle compensation structure is used to perform angle compensation on the welding gun, so that the welding gun can change the angle under the drive of the driving structure, so that when welding multiple sections of welds, the welding gun can change the angle autonomously to meet the welding requirements of welds in different extension directions, reduce the movement of the workpiece, and can maximize the integrity and consistency of the special-shaped welds after welding, avoid over-welding and cold welding at the weld joints, thereby further improving the welding quality;

[0014] Through the cooperation between the telescopic compensation structure and the angle compensation structure, it can better adapt to welds of different shapes and be competent for welding operations of various welds.

The driving wheel is rotatably connected to one end of the fixed block, and the wheel edge of the driving wheel is in contact with the spherical surface of the compensation ball head.

[0023] The angle control motor is fixed on one side of the fixed block and drives the driving wheel to rotate.

[0024] As a further supplement to the present application, a commutation motor is fixed to the upper end of the fixed plate, and the output shaft end of the commutation motor drives the driving structure to move in a circle along the axis of the angle compensation shaft through a telescopic compensation connecting piece.

Specifically, when the angle of the weld changes, it is only necessary to turn on the angle control motor, so that the angle control motor drives the driving wheel to rotate, and the driving wheel further drives the compensation ball head to roll in the spherical groove in a predetermined direction, so that the angle compensation shaft drives the welding gun to rotate accordingly, and the angle compensation spring can be elastically connected between the mounting block and the welding gun, so that the welding gun is more stable when it deflects with the angle compensation shaft. At the same time, it can also provide a deflection pulling force for the welding gun, so as to prevent the welding gun from rotating too quickly and leaving the weld, thereby realizing the angle compensation of the welding gun, so that when welding multiple sections of welds, the welding gun can change its angle autonomously to meet the welding requirements of welds with different extension directions, reduce the movement of the workpiece, and can maximize the integrity and consistency of the special-shaped weld after welding, avoid over-welding and cold welding at the weld joint, thereby further improving the welding quality;

[0047] The mounting structure includes a fixing plate 1 and a mounting block 2. The fixing plate 1 is fixed to the moving end of the liftable slide 500. The mounting block 2 is arranged between the fixing plate 1 and the welding gun 600.

[0048] An angle compensation structure is installed at the lower end of the mounting block 2 away from the fixing plate 1, and the mounting block 2 is rotatably connected to the upper end of the welding gun 600 through the angle compensation structure;

[0049] A driving structure 4 for driving the angle compensation structure to move is also installed in the mounting block 2. The driving structure 4 drives the welding gun 600 to swing at multiple angles through the angle compensation structure.

[0050] Based on the above structure, the telescopic compensation structure is used to provide telescopic compensation for the welding gun 600, so that the welding gun 600 can be telescoped at the lower end of the fixed plate 1, so as to perform adaptive welding on the weld of the protruding part or the concave part of the device to be welded, so that the welding gun (mainly refers to the end of the welding wire at the front end of the welding gun, the same below) is always in stable contact with the device during the welding process, thereby ensuring the welding quality; at the same time, the angle compensation structure is used to perform angle compensation on the welding gun, so that the welding gun can change the angle under the drive of the driving structure 4, so that when welding multiple sections of welds, the welding gun can change the angle autonomously to meet the welding requirements of welds in different extension directions, reduce the movement of the workpiece, and can maximize the integrity and consistency of the special-shaped weld after welding, avoid over-welding and cold welding at the weld joint, thereby further improving the welding quality;

[0051] Through the cooperation between the telescopic compensation structure and the angle compensation structure, it can better adapt to welds of different shapes and be competent for welding operations of various welds. At the same time, it can avoid the welding disadvantages existing in the existing technology, simplify the welding method and improve the welding quality.

[0052] Figure 2 and Figure 5 The telescopic compensation structure is shown to include a telescopic compensation support member 7, and the telescopic compensation support member 7 includes:

[0055] When the welding gun 600 moves along the weld, when a protruding part or a concave part appears on the weld, the front end of the welding gun 600 is subjected to a greater squeezing force at the weld or loses the squeezing force. At this time, the welding gun 600 squeezes the mounting block 2 or removes the squeezing force on the mounting block 2, so that the mounting block 2 further compresses the telescopic support sleeve 71 and the telescopic compensation spring 72, or extends under the elastic force of the telescopic compensation spring 72, thereby increasing the distance between the mounting block 2 and the fixed plate 1, so that the welding gun 600 can adaptively shrink or extend as the weld changes, thereby adapting to the protruding part or concave part of the weld, and realizing the telescopic compensation of the welding gun 600.

A plurality of angle compensation springs 5 ​​are provided, and the plurality of angle compensation springs 5 ​​are distributed circumferentially along the axis of the angle compensation shaft 3 .

[0059] When the angle of the weld changes, the driving structure 4 is used to drive the compensation ball head 31 at the upper end of the angle compensation shaft 3 to rotate tiltedly along the direction of movement, so that the angle compensation shaft 3 drives the welding gun 600 to rotate accordingly, and the angle compensation spring 5 can be elastically connected between the mounting block 2 and the welding gun 600, so that the welding gun 600 is more stable when deflected with the angle compensation shaft 3. At the same time, it can also provide a deflecting pulling force for the welding gun 600, thereby preventing the welding gun 600 from rotating too quickly and detaching from the weld, thereby achieving angle compensation for the welding gun 600.

[0060] Figure 4 and Figure 7 It is shown that a spherical embedding groove 21 is provided in the mounting block 2, which wraps the middle part of the compensation ball head 31 and forms an opening at the lower end.

[0063] When the angle of the welding gun 600 needs to be changed, it is only necessary to turn on the angle control motor 43 so that the angle control motor 43 drives the driving wheel 42 to rotate, and the driving wheel 42 further drives the compensation ball head 31 to roll in the spherical groove 21 in a predetermined direction, so that the welding gun 600 can be deflected through the angle compensation shaft 3 to change the angle of the welding gun 600.

[0064] Figure 3 , Figure 5 and Figure 7 It is shown that a reversing motor 8 is fixed to the upper end of the fixing plate 1, and the output shaft end of the reversing motor 8 drives the driving structure 4 to move in a circular motion along the axis of the angle compensation shaft 3 through the telescopic compensation connecting member 6;

[0065] The telescopic compensation connecting member 6 includes a connecting block 61 and a mounting plate 64. The upper end of the connecting block 61 is fixedly connected to the output shaft of the reversing motor 8. The mounting plate 64 is rotatably connected to the mounting groove 22.
