Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a convenient welding machine with multiple welding points. Background Art

[0002] In today's industrial manufacturing field, welding, as a key connection process, is widely used in many industries, such as automobile manufacturing, mechanical processing, and electronic equipment production. The quality of welding is directly related to the overall performance and safety of the product. Therefore, precise control of the welding process is crucial.

[0003] At present, traditional welding equipment has many drawbacks in actual operation. Especially when facing multi-point welding tasks, since the operation mainly relies on manual hand-held welding guns, operators need to hold the welding gun in the air for a long time to weld the parts to be welded placed on the platform. This process can easily cause hand fatigue; as the operation time increases, the hand shaking becomes more and more obvious, and the stability drops sharply. This unstable state directly affects the welding part, causing deviations in the position of the weld point, making it difficult to ensure the welding strength, and significantly increasing the defective rate, which seriously affects production efficiency and product quality, and brings high cost losses to the company; In addition, when there is a slightly larger gap in laser welding, welding wire must be used to ensure that the weld is full and continuous. Melting alone cannot fill the gap between the workpieces. In this welding process, the continuous supply of welding wire is indispensable. The welding wire is usually delivered to the welding part by a conveyor pipe. However, in actual production scenarios, due to the lack of awareness of regulations, the welding wire is easily damaged by bending. When it is used again, the bent part will produce greater resistance in the conveyor pipe, hindering the smooth delivery of the welding wire and even causing wire jamming. This not only leads to a waste of welding wire, but also frequent equipment commissioning and maintenance also consumes a lot of time and manpower, further disrupting the production rhythm and reducing production efficiency.

[0004] Therefore, the present invention proposes a convenient welding machine with multiple welding points to solve the above problems. Summary of the invention

[0005] In view of this, the technical problem to be solved by the present invention is to propose a multi-welding point convenient welding machine to solve the problems existing in the prior art.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a convenient welding machine with multiple welding points, comprising: a welding device, a push switch, a connecting auxiliary frame, and a welding wire conveying pipe, wherein the push switch is slidably connected to the welding device in a transverse direction, the connecting auxiliary frame is fixedly connected to the inner side wall of the welding device, and the welding wire conveying pipe is fixedly connected to the end of the connecting auxiliary frame, and further comprising: a first component, a second component, and a third component; The first component is used for movement stability of the welder when performing multi-spot welding; The second component is used to assist the welder in adjusting the height during stable welding, thereby increasing the adaptability range of the height of the welded workpiece; The third component is used to ensure that the welding wire in the welding wire conveying tube is in a non-bent state during operation when the welding wire is not being conveyed.

[0007] As an improvement, the first component includes an auxiliary plate fixedly connected to the welder, a driving shaft is fixedly connected to the auxiliary plate, and a thick shaft is movably sleeved on the driving shaft.

[0008] As an improvement, a supporting stand is fixedly connected to the outer ring surface of the thick shaft, and a rotating piece is rotatably connected to the bottom end of the supporting stand.

[0009] As an improvement, an extension piece is fixedly connected to the rotating piece, a column is fixedly connected to the bottom of the extension piece, and a rotating wheel is rotatably connected to the column.

[0010] As an improvement, the second component includes a ratchet plate fixedly connected to the auxiliary plate, and the ratchet plate is provided with concave tooth grooves at equal intervals.

[0011] As an improvement, a hexagonal column is fixedly connected to the end surface of the thick shaft rod, and a return spring is fixedly connected to the hexagonal column.

[0012] As an improvement, a fixing rod is fixedly connected to the end surface of the thick shaft rod, a limiting bar is rotatably connected to the fixing rod, and the limiting bar is fixedly connected to one end of the return spring.

[0013] As an improvement, the third component includes limiting notches equidistantly arranged on the supporting bracket, and a magnetic sheet is slidably connected to the column rod.

[0014] Compared with the prior art, the present invention provides a convenient welding machine with multiple welding points, which has the following beneficial effects: 1. The present invention significantly improves welding stability when performing supplementary welding of welding points through the design of a support tripod and a rotating wheel; that is, the additional support tripod provides a stable support foundation for the welder, effectively improving the welding scene on the basis of welding with an automatic laser welding machine, which is different from the hand shaking problem caused by long-term suspended operation of a manual hand-held welding gun; when the operator performs multi-point welding, the welder can be indirectly placed stably on the welding platform through the support tripod, which greatly reduces the position deviation of the welding points caused by hand fatigue, ensures that each welding point can be accurately positioned, and the welding strength can be reliably guaranteed. The defective rate is expected to be greatly reduced, thereby significantly improving the overall quality of the product; Improve operational convenience and flexibility: The rotating wheels under the support tripod allow the welder to slide freely on the welding platform; the operator does not need to move the body frequently or adjust the arm posture drastically. The operator only needs to use an external drive device and a drive rod to gently push the welder to quickly and conveniently move to different welding points, which greatly shortens the preparation time and operation stroke during the welding operation, greatly improves the efficiency of the welding work, and is especially suitable for multi-point welding tasks of complex structural parts.

[0015] 2. The present invention can accurately adapt to various welding height requirements by using the second component to participate in the work of the first component: that is, the support bracket and the welder are connected by rotation, and the second component with anti-reversal is equipped to realize the flexible adjustment of the angle between the two support brackets. This innovative design enables the height of the welder to be quickly and accurately adapted according to the different height requirements of the actual welding parts; whether facing a higher welding point or a lower fine welding part, the height of the welder can be easily adjusted to ensure that the welder is always at the best welding angle, which greatly expands the application scenarios of the welder, effectively avoids welding quality problems caused by inappropriate welding height, and further improves the welding yield of the product; Enhanced adaptability to complex working conditions: In multi-point welding tasks, the workpieces to be welded often have complex and changeable structures, and the heights of various welding parts are uneven; through the adjustable height design, the welder can adapt to such complex working conditions and seamlessly switch welding operations at different heights, reducing the cumbersome process of frequently changing equipment or adjusting tooling fixtures due to differences in workpiece heights, greatly improving the continuity and adaptability of the production process.

[0016] The present invention can effectively clamp the welding wire conveying tube by limiting the notch and designing the magnetic suction sheet, thereby simplifying the operation process and reducing labor intensity. The operator does not need to worry about the bending of the welding wire, nor does he need to spend extra energy to sort out and repair the bent welding wire, and the operation process is simplified; after the automatic laser welding task is completed, the welder with the welding wire conveying tube can be safely placed on the welding platform without worrying about it bending, which reduces the mental burden during the operation, reduces labor intensity, and enables the operator to focus more on the welding process itself, thereby improving work efficiency.

[0020] The present invention is further described in detail below based on the accompanying drawings and embodiments. Example

[0022] in: The first component 4 is used for stabilizing the movement of the welding machine 1 when performing multi-spot welding.

[0023] The driving shaft 402 and the thick shaft 403 are used in conjunction with each other to ensure the normal operation of the second component 5 , that is, the restriction state of the restriction bar 506 in the concave tooth groove 502 is released.

[0024] The rotating wheel 408 is used to assist the support stand 404 in stabilizing the movement of the welding machine 1 .

[0025] For further examples, please refer to Figures 3 to 7 As shown: The second component 5 is used to assist the welder 1 in adjusting the height during stable welding, thereby increasing the adaptability range of the height of the welded workpiece; the third component 6 is used to ensure that the welding wire in the welding wire conveying tube 3 is in a non-bent state during operation when the welding wire is not being conveyed. The second component 5 includes a ratchet plate 501 fixedly connected to the auxiliary plate 401, and the ratchet plate 501 is provided with concave tooth grooves 502 at equal intervals. A hexagonal column 503 is fixedly connected to the end face of the thick shaft rod 403, and a return spring 504 is fixedly connected to the hexagonal column 503. A fixing rod 505 is fixedly connected to the end face of the thick shaft rod 403, and a limiting strip 506 is rotatably connected to the fixing rod 505, and the limiting strip 506 is fixedly connected to one end of the return spring 504. The third component 6 includes limiting recesses 601 equidistantly provided on the supporting leg 404, and a magnetic suction sheet 602 is slidably connected to the column rod 407.

[0026] in: The second component 5 is used to assist the welder 1 in adjusting its height during stable welding, thereby increasing the adaptability range of the height of the welded workpiece.

[0027] The return spring 504 is used to cooperate with the movement of the limiting bar 506 .

[0028] The limiting strip 506 is matched with the concave tooth groove 502 .

[0029] The third component 6 is used to ensure that the welding wire in the welding wire conveying tube 3 is in a non-bent state during operation when the welding wire is not being conveyed.

[0030] The limiting notch 601 formed on the inner side of the supporting bracket 404 is mainly used to clamp the welding wire conveying tube 3 therein, so as to prevent the welding wire therein from bending and affecting the normal conveying work during use.

[0031] There are two magnetic sheets 602 , which can stably fix the corresponding two supporting legs 404 after being magnetically attracted to each other.

[0032] Everything in the above example works like this: It should be noted that this device is added near the optical fiber of the automatic laser welding machine to adapt to the gap supplementary welding work that occurs in workpieces of different models and types.

[0033] Working steps: Place the required welding workpiece on the jig; press the jig cylinder to complete the product pre-pressing; start the switch, the workpiece moves to the optical fiber and stops, and then welds the welding spot; after the welding work is completed, remove the product for visual inspection.

[0034] In the initial state: The welding wire conveying tube 3 is located in the limiting notch 601 opened on the supporting leg 404 , the two magnetic suction plates 602 are magnetically attracted to each other, the return spring 504 is not compressed, and the limiting bar 506 is clamped on the inner concave tooth groove 502 .

[0035] When supplementary welding is used, the operator first separates the two support legs 404 through the control system, that is, Figure 1 The status is adjusted to Attached Figure 2 state, and then specifically adjust the angle between the two support legs 404 according to the required welding height. Specifically, when separating the attached support legs 404, the support legs 404 will rotate under the drive of the driving shaft 402 through the thick shaft rod 403. During the rotation, the limiting strip 506 on the thick shaft rod 403 will move in the concave tooth groove 502. During this process, the return spring 504 is in a state of compression, release, and compression again to ensure the stable movement of the limiting strip 506 with the fixed rod 505 as the rotation axis, that is, the support legs 404 can only perform unidirectional rotation under the action of the second component 5. Furthermore, if the one-way rotation state is to be released, the thick shaft 403 on the driving shaft 402 only needs to be slid so that the limiting strip 506 on the thick shaft 403 is no longer stuck in the concave tooth groove 502 on the ratchet piece 501 fixedly connected to the auxiliary plate 401; Furthermore, after the angle of the support stand 404 is adjusted, the welder can control the welder 1 body through the external driving rod, and then slide on the welding platform under the action of the rotating wheel 408 provided at the bottom of the support stand 404, so as to ensure the moving stability of the welder 1, and perform welding work on the joint of the components by pressing the push switch 101 to deliver the welding wire from the welding wire delivery pipe 3; Furthermore, after the welding work is finished, the welding wire delivery tube 3 can be placed in the limiting notch 601 provided on the supporting bracket 404 and stably clamped and fixed with the assistance of the magnetic sheet 602; Furthermore, the support tripod 404 and the rotating wheel 408 are designed to significantly improve the welding stability when performing supplementary welding of welding points; that is, the additional support tripod 404 provides a stable support foundation for the welder 1, effectively improving the welding scene on the basis of welding with an automatic laser welding machine, which is different from the hand shaking problem caused by long-term suspended operation of a manual hand-held welding gun; when the operator performs multi-point welding, the welder 1 can be indirectly placed stably on the welding platform through the support tripod 404, which greatly reduces the position deviation of the welding points caused by hand fatigue, ensures that each welding point can be accurately positioned, and the welding strength can be reliably guaranteed. The defective rate is expected to be greatly reduced, thereby significantly improving the overall quality of the product; Improve operational convenience and flexibility: The rotating wheel 408 provided under the supporting tripod 404 enables the welder 1 to slide freely on the welding platform; the operator does not need to frequently move the body or drastically adjust the arm posture, but only needs to use an external driving device and a driving rod to gently push the welder 1 to quickly and conveniently move to different welding points, which greatly shortens the preparation time and operation stroke during the welding operation, greatly improves the efficiency of the welding work, and is especially suitable for multi-point welding tasks of complex structural parts.

[0036] Furthermore, by the second component 5 participating in the work of the first component 4, various welding height requirements can be accurately adapted: that is, the support bracket 404 and the welder 1 are connected by rotation, and the anti-reversal second component 5 is equipped to realize the flexible adjustment of the angle between the two support brackets 404. This innovative design enables the height of the welder 1 to be quickly and accurately adapted according to the different height requirements of the actual welding parts; whether facing a higher welding point or a lower fine welding part, the height of the welder 1 can be easily adjusted to ensure that the welder 1 is always at the best welding angle, which greatly expands the application scenarios of the welder 1, effectively avoids welding quality problems caused by inappropriate welding height, and further improves the welding yield of the product; Enhanced adaptability to complex working conditions: In multi-point welding tasks, the workpieces to be welded often have complex and changeable structures, and the heights of various welding parts are uneven; through the adjustable height design, the welder 1 can adapt to such complex working conditions and seamlessly switch welding operations at different heights, reducing the cumbersome process of frequently changing equipment or adjusting tooling fixtures due to differences in workpiece heights, greatly improving the continuity and adaptability of the production process.

[0037] Furthermore, by limiting the design of the notch 601 and the magnetic sheet 602, the welding wire delivery tube 3 can be effectively clamped, simplifying the operation process and reducing labor intensity. The operator does not need to worry about the bending of the welding wire, nor does he need to spend extra energy to sort out and repair the bent welding wire, and the operation process is simplified; after the automatic laser welding task is completed, the welder 1 with the welding wire delivery tube 3 can be safely placed on the welding platform without worrying about it bending, which reduces the mental burden during the operation, reduces labor intensity, and enables the operator to focus more on the welding process itself and improve work efficiency.
