Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, specifically a welding device for endoscope metal components. Background Technology

[0002] Endoscopes, as indispensable key equipment in industrial inspection and medical diagnosis, play a vital role in many precision operation scenarios due to their unique imaging and observation capabilities. Their internal structure is intricate and complex, composed of numerous interconnected components. These components often require welding during manufacturing and subsequent maintenance to achieve a stable connection between two independent workpieces.

[0003] Endoscope components are uniquely designed, with most exhibiting a cylindrical structure. While this structure fulfills the functional requirements of endoscopes to some extent, it presents challenges for clamping and securing them during the welding process. Existing welding equipment has significant limitations when clamping these cylindrical parts. Typically, the equipment can only ensure precise alignment of one side of the component; however, for welding endoscope components, side alignment alone is far from sufficient. To achieve high-quality welding, the axes of the two components to be welded must be strictly aligned to ensure uniform stress and structural stability at the weld joint, thereby guaranteeing the overall performance and reliability of the endoscope.

[0004] However, in practice, precisely aligning the axes of two cylindrical parts is no easy task. Existing welding equipment lacks effective axis alignment assistance functions. Operators often need to rely on extensive experience and superb skills, making repeated and meticulous adjustments to barely bring the axes of the parts to a roughly straight line. This process not only consumes a lot of time and energy but also demands a very high level of skill from the operator. The slightest carelessness can lead to welding deviations, affecting the quality of the endoscope, or even damaging components, increasing production costs and maintenance difficulties. Summary of the Invention

The base is provided with two left and right fixed structures, and a sliding groove is provided on the base. A rotatable track is provided in the sliding groove. The fixed structures cooperate with the track so that when the track rotates, the two fixed structures can move closer to or further away from each other.

Multiple pawls are arranged in a circular array on the fixing plate, and a rotatable actuating plate is also provided inside the fixing plate. The pawls cooperate with the actuating plate, and a rotatable actuating element is provided on the fixing plate. When the actuating element rotates, the actuating plate can rotate accordingly; thereby fixing / releasing the workpiece to be welded.

[0008] A wiping strip is installed inside the channel of the fixed frame. The wiping strip is connected to the inner wall of the fixed frame through an elastic connecting post. When the fixed frame moves, the wiping strip can be tightened and wrapped around the surface of the welded part that passes through the fixed frame.

The actuating member and the actuating disk are driven by a gear and rack meshing. A push rod is provided inside the fixed seat, and a first limiting tooth is fixedly connected to the push rod. A second limiting tooth is provided on the surface of the actuating member. Both the first and second limiting teeth are arranged at an angle, and the first limiting tooth is elastic, so that when the second limiting tooth rotates in one direction, the second limiting tooth can pass over the first limiting tooth, but when the second limiting tooth rotates in the other direction, the second limiting tooth cannot pass over the first limiting tooth.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Depend on Figure 1-8 The present invention discloses a welding device for endoscope metal components, including a base 1, an outer cover 2 on the base 1, and a welding mechanism 3 inside the outer cover 2. The base 1 is provided with two fixed structures on the left and right, and a sliding groove 5 is opened on the base 1. A rotatable track 6 is provided in the sliding groove 5. The fixed structures cooperate with the track 6 so that when the track 6 rotates, the two fixed structures can move closer to or further away from each other.

[0029] The fixing structure includes a fixing disk 4 and a fixing frame 7, both of which have through channels. The fixing frame 7 is located on one side of the fixing disk 4. Multiple pawls 22 are arranged in a circular array on the fixing disk 4, and a rotatable actuating disk 23 is also provided inside the fixing disk 4. The pawls 22 cooperate with the actuating disk 23. A rotatable actuating element 24 is provided on the fixing disk 4. When the actuating element 24 rotates, the actuating disk 23 can rotate accordingly, thereby fixing / releasing the workpiece to be welded. Through the implementation of the pawls 22, after ensuring that the two fixing disks 4 are on the same straight line, the central axes of the two workpieces to be welded can also be ensured to be on the same straight line, thereby ensuring that the two workpieces can be aligned and meet the requirements after welding.

[0030] A wiping belt 17 is provided in the channel of the fixed frame 7. The wiping belt 17 is connected to the inner wall of the fixed frame 7 through the elastic connecting post 18. When the fixed frame 7 moves, the wiping belt 17 can be tightened and wrapped around the surface of the welded part passing through the fixed frame 7.

[0031] When this device is implemented, the user places the workpiece to be welded into the fixed structure. The fixing plate 4 can fix the workpiece to be welded, and the setting of the two fixing plates 4 on the left and right can ensure that the two workpieces are in the same straight line when they are fixed, thus ensuring the smooth progress of the subsequent welding process. After the workpiece is fixed, the fixing plate 4 slides into the inner part of the outer cover 2. During the sliding process, the wiping belt 17 can wrap around the surface of the workpiece. Then the fixing frame 7 is pushed forward, so that the wiping belt 17 wipes the surface of the workpiece to remove dust, oil and other stains. After wiping, the wiping belt 17 can separate from the surface of the workpiece, and then the fixing frame 7 resets. Then, as the fixing plate 4 continues to move forward, the two workpieces to be welded together come into contact to perform the welding operation.

[0032] The lower end of the fixed disk 4 is fixedly connected to a first bracket 10, the track 6 passes through the first bracket 10, a first rotating wheel 11 that can rotate is provided in the first bracket 10, a rotating shaft 12 is fixedly connected to the axis of the first rotating wheel 11, a first transmission gear 13 is fixedly connected to the rotating shaft 12, a movable rod 14 is provided in the first bracket 10, the movable rod 14 and the first transmission gear 13 mesh with each other, and one end of the movable rod 14 is fixedly connected to the fixed frame 7 so that when the first rotating wheel 11 rotates, the fixed frame 7 can be pushed away from the fixed disk 4.

[0033] The track 6 can be a threaded rod or a linear module, etc., and this application does not impose any restrictions. Its driving method can be driven by a motor. Moreover, for endoscopes, their structure is generally small, and a scope tube (not shown in the figure) can also be provided on the outer cover 2 to allow the user to observe the welding position.

[0034] The lower end of the fixed frame 7 is fixedly connected to a second bracket 16. A second rotating wheel 20 that can rotate is provided inside the second bracket 16. A central shaft 19 and a second transmission gear 21 are also provided inside the second bracket 16. The central shaft 19 and the second transmission gear 21 are coaxially fixed together, and the second transmission gear 21 and the second rotating wheel 20 mesh with each other. One end of the wiping belt 17 is fixedly connected to the inner wall of the fixed frame 7, and the other end of the wiping belt 17 passes over the position of its first end and is wrapped around the central shaft 19.

[0035] The side of the slide groove 5 is provided with a first actuating tooth 8 and a second actuating tooth 9. The first actuating tooth 8 can cooperate with the second rotating wheel 20 to make the second rotating wheel 20 rotate. The second actuating tooth 9 can cooperate with the first rotating wheel 11 to make the first rotating wheel 11 rotate. There are two sets of the first actuating tooth 8 and the second actuating tooth 9, which can cooperate with the opposite sides of the first rotating wheel 11 and the second rotating wheel 20 respectively.

[0036] like Figure 1 As shown, in this implementation, there are first actuating teeth 8 and second actuating teeth 9 above and below the slide groove 5. When the fixed plate 4 moves to the middle position, the fixed plate 4 can push the fixed frame 7 to move together, and the second rotating wheel 20 inside the fixed frame 7 can first cooperate with the first actuating tooth 8, so that the wiping belt 17 is wrapped around the surface of the workpiece to be welded. Then the second rotating wheel 20 separates from the first actuating tooth 8, and the first rotating wheel 11 cooperates with the second actuating tooth 9. At this time, the fixed frame 7 is pushed away from the fixed plate 4, so that the wiping belt 17 and the workpiece to be welded slide relative to each other, thereby wiping the surface of the workpiece. After wiping, the second rotating wheel 20 cooperates with the first actuating tooth 8 located below. At this time, the second rotating wheel 20 reverses, thereby separating the wiping belt 17 from the workpiece. Then, under the action of the second actuating tooth 9 located below, the fixed frame 7 returns to its original position. Then, the fixed plate 4 continues to move forward until the two workpieces to be welded come together. At this time, the workpieces can be welded by using the welding mechanism 3.

[0037] A fixed base 25 is fixedly attached to the surface of the fixed disk 4. The actuating member 24 passes through the fixed base 25 and the two are engaged by a torsion spring 26. The actuating member 24 and the actuating disk 23 are driven by a gear and rack meshing. A push rod 29 is provided inside the fixed base 25. A first limiting tooth is fixedly attached to the push rod 29. A second limiting tooth is provided on the surface of the actuating member 24. Both the first and second limiting teeth are arranged at an angle. The first limiting tooth is elastic so that when the second limiting tooth rotates in one direction, the second limiting tooth can pass over the first limiting tooth, but when the second limiting tooth rotates in the other direction, the second limiting tooth cannot pass over the first limiting tooth.

[0038] After the workpiece passes through the fixed plate 4 and the fixed frame 7, the pawl 22 can be moved by rotating the actuating element 24, thereby fixing the position of the workpiece. The engagement of the first and second limiting teeth maintains stability after the workpiece is fixed, and the torsion spring 26 is in a stored energy state at this time. After the workpiece welding is completed, the pawl 22 needs to be released. By moving the push rod 29, the first and second limiting teeth are separated. At this time, the actuating element 24 will reverse under the action of the torsion spring 26, thereby separating the pawl 22 so that the user can remove the welded workpiece.

[0039] The push rod 29 is connected to the fixed base 25 by a spring 30, and one end of the push rod 29 extends out of the fixed base 25. A toggle rod 28 is provided on the outer cover 2. The toggle rod 28 can slide, and the side of the toggle rod 28 can cooperate with the push rod 29 so that when the toggle rod 28 slides, the push rod 29 can slide to one side. The use of the spring 30 allows the push rod 29 to remain in its original position when it is not subjected to external force.

[0040] An actuating block 27 is provided on the outer cover 2, and the actuating block 27 and the actuating rod 28 are engaged with each other.
