At first, under the action of the elastic limiting mechanism A, the two first sliding mechanisms do not move, and the distance between the upper clamping plate and the lower clamping plate of the same clamping mechanism is reduced, so that the corresponding pipes are clamped. After that, the two articulated frames continue to approach each other, and the distance between the upper clamping plate and the lower clamping plate of the same clamping mechanism remains unchanged. The two first sliding mechanisms approach each other, driving the two pipes to approach and contact each other.

At first, under the action of the elastic limiting mechanism A, the two first sliding mechanisms do not move, so that the articulated frame moves, driving the upper clamping plate and the lower clamping plate to move relative to each other, and the distance between the upper clamping plate and the lower clamping plate of the same clamping mechanism is reduced, so that the corresponding pipe is clamped. After clamping, the two articulated frames are continued to be pushed by the push-pull mechanism. Since the distance between the upper clamping plate and the lower clamping plate of the same clamping mechanism cannot be further reduced, the elastic mechanism A will be overcome, and the two first sliding mechanisms are used to approach each other, driving the two parts of the pipe to be welded to approach each other until they touch each other, completing the positioning of the two parts of the pipe to be welded, and finally welding can be performed.

DETAILED DESCRIPTION

[0033] The following will refer to the attached Figures 1 to 7 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] A variable adaptable sports equipment welding device, as shown in the attached Figure 1As shown, it includes two clamping mechanisms arranged on the left and right, and the clamping mechanism includes a first sliding mechanism 16 along the vertical direction, and the upper clamping plate 15 and the lower clamping plate 14 are slidably connected on the first sliding mechanism 16, and a hinge frame is provided between the upper clamping plate 15 and the lower clamping plate 14, and the hinge axis of the hinge frame is along the front-back direction. In this embodiment, the hinge frame includes an upper hinge rod 13, a hinge seat 12 and a lower hinge rod 11, the upper hinge rod 13 is hinged to the upper clamping plate 15 and the hinge seat 12 respectively, and the lower hinge rod 11 is hinged to the lower clamping plate 14 and the hinge seat 12 respectively, and the hinge seat 12 is always facing inward, and the distance between the upper clamping plate 15 and the lower clamping plate 14 is controlled by controlling the relative movement between the hinge frame and the first sliding mechanism 16; it also includes a second sliding mechanism 20 along the left and right direction, and the two clamping mechanisms are slidably arranged on the second sliding mechanism 20, and an elastic limiting mechanism A is provided between the second sliding mechanism 20; it also includes a push-pull mechanism for pushing and pulling the hinge frame.

[0035] Working principle: Taking the clamping mechanism on the left side as an example, when the hinge seat 12 is pushed to move to the right, due to the action of the elastic limiting mechanism A, at first, the first sliding mechanism 16 does not move, and the upper clamp plate 15 and the lower clamp plate 14 are close to each other, so that the upper clamp plate 15 and the lower clamp plate 14 can be clamped. After the clamping is completed, when the upper clamp plate 15 and the lower clamp plate 14 cannot continue to move close to each other, if the hinge seat 12 continues to be pushed to the right, it will drive the first sliding mechanism 16, the upper clamp plate 15 and the lower clamp plate 14 to move to the right together.

[0036] like Figure 1 , Figure 7 As shown, in actual use, it is only necessary to place the two parts of the pipe 34 to be welded on the two clamping mechanisms at a certain angle as needed so that the welding points correspond, and then push the two hinged seats 12 close to each other through the push-pull mechanism, so that the pipe 34 can be clamped by the upper clamping plate 15 and the lower clamping plate 14 first, and then drive the two clamping mechanisms close to each other, and finally make the welding points of the two parts of the pipe 34 to be welded contact, achieve positioning, and then weld, which is simple to operate.

[0037] In addition, it should be noted that the present invention, when used specifically, is mainly aimed at some pipes 34 that can be manually taken in and out and have a relatively light overall mass. The pipes 34 can be placed on the clamping mechanism more stably and are not prone to tilting. When the pipes 34 are initially clamped, the pipes 34 can also be manually supported to ensure the stability of the pipes 34.

[0038] During operation, the present invention only needs to control the push-pull mechanism to push the articulated frame to achieve rapid positioning, which is simple to operate and saves time and effort. The present invention can adapt to pipes 34 of different specifications, and only needs to control the push-pull mechanism to push the articulated frame to position pipes 34 of different specifications, which is flexible and convenient to use. When positioning the pipe 34, the present invention first does not move the pipe 34 in the horizontal direction, which can ensure the placement angle of the pipe 34. After being clamped by the clamping mechanism, the pipe 34 is moved horizontally, and then the two parts of the pipe 34 are brought into contact with each other, thereby reducing the skewness of the pipe 34 during positioning and movement, resulting in an error in the angle after positioning, thereby improving the accuracy of welding.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, in this embodiment, the clamping mechanism is provided with a discharge mechanism with an adjustable angle, and the discharge mechanism includes a third sliding mechanism 25 rotatably arranged on the lower clamping plate 14, and the third sliding mechanism 25 is along the horizontal direction. A fixed side clamping plate 29 is fixedly connected to the third sliding mechanism 25, and a movable side clamping plate 28 is slidably connected. In this embodiment, the fixed side clamping plate 29 is close to the inner side, and the movable side clamping plate 28 is close to the outer side. An elastic limiting mechanism B is provided between the movable side clamping plate 28 and the third sliding mechanism 25, and the elastic limiting mechanism B includes a fixed plate B26 fixedly connected to the third sliding mechanism 25, and a spring B27 is provided between the fixed plate B26 and the movable side clamping plate 28.

[0040] Working principle: The spring B27 generates a thrust on the movable side clamp 28, so that the movable side clamp 28 is close to the fixed side clamp 29. When placing the pipe 34, the pipe 34 can be placed between the movable side clamp 28 and the fixed side clamp 29, and supported by the third sliding mechanism 25. The movable side clamp 28 and the fixed side clamp 29 can temporarily limit the pipe 34.

[0041] In this embodiment, a telescopic rod 17 is fixedly connected to the fixed plate B26. The telescopic rod 17 is along the vertical direction. The top of the telescopic rod 17 passes through the upper clamping plate 15 and is rotatably connected to the upper clamping plate 15. A turntable 19 is provided at the top. A positioning hole is provided on the turntable 19. The turntable 19 is provided with a socket that matches the positioning hole. The turntable 19 is fixed to the upper clamping plate 15 by a movable latch 18.

[0042] Working principle: By rotating the rotating connection of the third sliding mechanism 25, it is convenient to adjust the angle of the pipe 34. Through the telescopic structure of the telescopic rod 17, it can adapt to different positions of the upper clamping plate 15 and the lower clamping plate 14. When the third sliding mechanism 25 rotates, it drives the telescopic rod 17 to rotate, and the telescopic rod 17 drives the turntable 19 to rotate. The position of the turntable 19 is fixed by the movable latch 18, thereby fixing the angle of the third sliding mechanism 25, which plays a role of temporarily limiting the pipe 34.

[0043] In this embodiment, slots are provided on the top of the movable side clamp plate 28 and the fixed side clamp plate 29, and limit rods 30 are inserted through the slots. In this embodiment, two front and rear slots are provided on the top of the movable side clamp plate 28 and the fixed side clamp plate 29 respectively, and one discharge mechanism is equipped with a total of 4 limit rods 30.

[0044] Working principle: By taking and placing the limiting rod 30 , the pipe 34 can be smoothly taken and placed, and the limiting rod 30 can better limit the pipe 34 .

[0045] During specific use, the discharge mechanism on the left clamping mechanism can be discharged first. Specifically, the limit rod 30 on the fixed side clamping plate 29 on the left clamping mechanism can be removed to facilitate the placement of the pipe 34. After placing the pipe 34, the limit rod 30 on the fixed side clamping plate 29 is inserted, and then the third sliding mechanism 25 is controlled to rotate and fixed by the movable latch 18 to achieve temporary fixation of the pipe 34; then through the same operation, another pipe 34 is set on the discharge mechanism of the right clamping mechanism. When setting, the welding points of the two pipes 34 correspond to each other, and the angles correspond to each other. Finally, the push-pull mechanism is controlled to work to complete the final positioning.

[0046] It should be noted that when the limiting rod 30 is installed, it can be used flexibly according to the rotation direction of the third sliding mechanism 25, such as Figure 5 As shown, when the third sliding mechanism 25 on the left side rotates clockwise, the limiting rod 30 on the rear side can be removed and limited by the limiting rod 30 on the front side, thereby ensuring that the limiting rod 30 and the upper clamping plate 15 will not affect each other, thereby ensuring smooth rotation.

[0047] In this embodiment, a baffle plate 31 is provided below the upper clamp plate 15, and the baffle plate 31 is fixedly connected to the telescopic rod 17 near the top, that is, the distance between the upper baffle plate 31 and the upper clamp plate 15 remains unchanged, and the midpoint between the upper clamp plate 15 and the lower clamp plate 14 and the midpoint between the baffle plate 31 and the third sliding mechanism 25 are at the same height. Specifically, the pipe 34 is directly contacted and clamped by the baffle plate 31 and the third sliding mechanism 25, and the distance between the pipe 34 and the upper clamp plate 15 and the lower clamp plate 14 is the same. By determining the height of the hinge seat 12, the height of the pipe 34 after being fixed can be determined.

[0048] like Figure 1 , Figure 2 As shown, in this embodiment, a slider 24 adapted to the second sliding mechanism 20 is provided at the bottom of the first sliding mechanism 16, and the first sliding mechanism 16 is slidably connected to the second sliding mechanism 20 through the slider 24. The elastic limiting mechanism B includes a fixed plate A22 fixedly connected to the second sliding mechanism 20, and a spring A23 is provided between the fixed plate A22 and the slider 24, and the spring A23 plays an elastic limiting role on the first sliding mechanism 16.

[0049] like Figure 1 As shown, Figure 7 As shown, the push-pull mechanism in this embodiment includes a support frame fixedly arranged below the second sliding mechanism 20, the support frame includes a base plate 1 and side plates 7 located on the left and right sides of the base plate 1, and is connected to the second sliding mechanism 20 through the side plates 7. A motor 4 and a control switch 5 for controlling the motor 4 are provided on the base plate 1. The motor 4 is connected to a driving gear 3, and the driving gear 3 is meshingly connected to a driven gear 21. The driven gear 21 penetrates the rod body 2 along the left and right directions. The rod body 2 passes through the side plates 7 and is provided with a threaded section 8 at the end. The two threaded sections 8 are in opposite directions, and a connecting plate 9 is threadedly connected through the threaded section 8. The connecting plate 9 is connected to the articulated frame, and specifically, is connected to the articulated seat 12 through a push-pull rod 10.

[0050] Working principle: The motor drives the rod body 2 to rotate, thereby driving the threaded segment 8 to rotate, and the two threaded segments 8 control the two connecting plates 9 to move closer to or away from each other without changing the height of the articulated seat 12.

[0051] During specific use, the middle heights of the two parts of the pipe 34 after positioning are the same. Even if the specifications of the two parts of the pipe 34 to be welded are different, the pipe 34 with a smaller diameter can be pressed against the middle height position of the pipe 34 with a larger diameter, which is more suitable for normal welding use and faster positioning.

[0052] like Figure 1 , Figure 6 As shown, the connecting plate 9 is a telescopic structure and is provided with a fixing part for controlling the telescopic length of the connecting plate 9. By adjusting the telescopic length of the connecting plate 9, the height of the push-pull rod 10 can be adjusted, and then the height of the articulated seat 12 can be adjusted to control the clamping height, which is more flexible to use and can meet various welding needs.

[0053] In this embodiment, a fixing seat 6 is provided on the bottom plate 1, which is used to fix the entire device through the fixing seat 6 to ensure the stability of the device and facilitate welding work.

[0054] like Figure 1 , Figure 6 As shown, in this embodiment, a rotating ring 32 is passed through the connecting plate 9, and a friction member is provided on the rotating ring 32, which may be a rubber layer, for increasing the friction between the rotating ring 32 and the connecting plate 9. A thread matching the threaded segment 8 is provided on the inner side of the rotating ring 32. The threaded segment 8 is threadedly connected to the connecting plate 9 through the rotating ring 32, and a baffle 33 is provided at one end of the threaded segment 8 away from the rod body 2.

[0055] Working principle: Under the action of the friction parts, the rotating ring 32 does not rotate at ordinary times. When the threaded segment 8 rotates, the rotating ring 32 does not rotate, thereby driving the connecting plate 9 to move. When the threaded segment 8 rotates, the baffle 33 and the connecting plate 9 approach each other until they contact. The threaded segment 8 continues to rotate, and the distance between the baffle 33 and the connecting plate 9 cannot continue to change, thereby driving the rotating ring 32 to rotate.

[0056] In specific operation, when taking materials after welding is completed, the threaded section 8 is controlled to rotate, and the two connecting plates 9 are driven to move outward, that is, the two connecting plates 9 are away from each other, so that the connecting plates 9 and the blocking plate 33 are close to each other. Since the two pipes 34 are welded and fixed to each other, they are limited to each other, so that the upper clamping plate 15 and the lower clamping plate 14 are away from each other at the beginning, the clamped pipe 34 can be loosened and the pipe 34 can be removed; then the threaded section 8 continues to rotate, driving the two clamping mechanisms away from each other. Since the two clamping mechanisms move successively on the second sliding mechanism 20 when positioning two pipes 34 of different specifications, when the two clamping mechanisms move away from each other, one clamping mechanism moves to the outermost side first. When one clamping mechanism moves to the outermost side first, since the connecting plate 9 cannot continue to move outward, when the threaded section 8 continues to rotate, by driving the rotating ring 32 to rotate, the other connecting plate 9 continues to move outward, and finally the two connecting plates 9 can move to the outermost side, so that the two clamping mechanisms are reset.

[0057] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0058] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
