Description

Technical Field

[0001] This utility model relates to the field of rear frame welding technology, specifically an auxiliary construction device for rear frame welding processing. Background Technology

[0002] The frame is an important component of the structure of a vehicle (especially motorcycles, bicycles, electric vehicles, and some small cars or special vehicles). It connects the rear wheel, rear suspension system, rear braking system, and rear structure of the vehicle body, and undertakes the important functions of supporting, bearing, and transmitting loads. In the production of the rear frame, it needs to be welded.

[0003] When welding the existing rear frame, some auxiliary devices support the rear frame through a suspended support frame to raise it to a suitable height for welding. However, the support frame structure is relatively fixed, making it inconvenient to lift the rear frame and place it on the support frame, which makes the auxiliary devices inconvenient to use. Therefore, an auxiliary construction device for welding the rear frame is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An auxiliary construction device for welding rear frame, comprising a base, a rotating rod rotatably connected to the inner side of the base, a rotating plate fixedly connected to the outer side of the rotating rod, a support frame rotatably connected to the outer side of the rotating plate, a threaded rod (both positive and negative threads) rotatably connected to the inner side of the support frame, a clamping plate threaded to the outer side of the threaded rod, a limiting rod slidably connected to the inner side of the clamping plate, the limiting rod being fixedly connected to the support frame, a slider fixedly connected to the outer side of the support frame, a connecting frame slidably connected to the outer side of the slider, a hydraulic cylinder fixedly connected to the inner side of the base, and the output end of the hydraulic cylinder being fixedly connected to the connecting frame; this step involves setting up a rotating rod, a rotating plate, a support frame, a slider, and... The connecting frame and hydraulic cylinder are used to move the connecting frame when placing the rear frame. The connecting frame moves the support frame, which in turn moves the rotating plate. The rotating plate moves the support frame downwards, and when the support frame reaches its lowest point, the rear frame is lifted and placed on top of the support frame. After placement, the positive and negative threaded screws are rotated, causing the clamping plates to move closer together and clamp and fix the rear frame. The hydraulic cylinder moves the connecting frame in the opposite direction, which in turn moves the slider. The slider pulls the support frame in the opposite direction, causing one end of the rotating plate to rotate and rise. This causes the support frame to lift the rear frame, facilitating welding and making it easier to place the rear frame on top of the support frame, thus improving the ease of use of the device.

[0006] Preferably, an inclined plate is fixedly connected to the outer side of the base, and a roller is rotatably connected to the inner side of the inclined plate. This step, by setting the inclined plate and the roller, allows the rear frame to be moved to the inclined surface near the inclined plate after welding, driven by the support frame. The clamp is then released, and the rear frame is pushed to slide down the inclined surface of the inclined plate. At the same time, the rear frame will first come into contact with the roller to generate friction. The roller rotates, making the sliding of the rear frame smoother, thus facilitating its separation and removal from the device, and improving the convenience of using the device.

[0007] Preferably, slots are provided on the inner side of both the base and the support frame. A rod is slidably connected to the inner side of the slot, and a synchronization plate is fixedly connected to the outer side of the rod. This step, by setting up slots, rods, and synchronization plates, allows the support frame to rotate and rise. By pushing the synchronization plate, multiple rods can be inserted into the slots on the inner side of the base or support frame. The base restricts the position of the rods on its inner side, thereby further restricting the position of the synchronization plate. In turn, the synchronization plate restricts the position of the rods and the support frame on the other side, making the position of the support frame more stable and improving the stability of the device.

[0008] Preferably, a baffle is fixedly connected to the outer side of the base, and the baffle works in conjunction with the rotating plate. This step, by setting the baffle, restricts the position of the rotating plate when it rotates to its maximum position by sticking the baffle to the rotating plate, thereby making it difficult for the rotating plate to continue moving, making it difficult for the hydraulic cylinder to drive the rotating plate to rotate excessively, and improving the stability of the device.

[0009] Preferably, a limiting groove is formed on the inner side of the base, and a limiting strip is fixedly connected to the inner side of the limiting groove. The limiting strip and the connecting frame are fixedly connected. This step, by setting the limiting groove and the limiting strip, allows the limiting groove to restrict the limiting strip when the connecting frame moves, thereby further restricting the movement trajectory of the connecting frame, making its movement more stable and less prone to shaking, and improving the stability of the device.

[0010] Preferably, a movable plate is slidably connected to the inner side of the base, and the movable plate is used in conjunction with the support frame. This step, by setting the movable plate, allows the support frame to move to its highest position. By inserting a portion of the movable plate into the inner side of the base, one end of the movable plate is pressed against the lower side of the support frame, thereby further restricting and supporting the position of the support frame, making its placement more stable and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a rotating rod, a rotating plate, a support frame, a slider, a connecting frame, and a hydraulic cylinder, allows the rear frame to be placed. When placing the rear frame, the hydraulic cylinder drives the connecting frame to move, which in turn pushes the support frame to move. Simultaneously, the support frame drives the rotating plate to move and rotate, and the rotation of the rotating plate causes the support frame to move downward. When the support frame moves to its lowest position, the rear frame is lifted and placed on the support frame. After placement, the positive and negative threaded screws are rotated, causing the clamping plates to move closer together to clamp and fix the rear frame. The hydraulic cylinder drives the connecting frame to move in the opposite direction, which in turn drives the slider to move. This causes the slider to pull the support frame to move in the opposite direction, causing one end of the rotating plate to rotate and rise. This allows the support frame to lift the rear frame, facilitating welding and making it easier to place the rear frame on the support frame, thus improving the ease of use of the device.

[0013] 2. By setting up an inclined plate and a roller, after the rear frame is welded, it is moved to the inclined surface near the inclined plate by the support frame. The clamp is released, and the rear frame is pushed to slide down the inclined surface of the inclined plate. At the same time, the rear frame will first come into contact with the roller to generate friction. The roller rotates, making the sliding of the rear frame smoother, which makes it easier to separate and remove it from the device, thus improving the convenience of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, an auxiliary construction device for welding a rear frame includes a base 1. A rotating rod 2 is rotatably connected to the inner side of the base 1. A rotating plate 3 is fixedly connected to the outer side of the rotating rod 2. A support frame 4 is rotatably connected to the outer side of the rotating plate 3. A threaded rod 5 with both positive and negative threads is rotatably connected to the inner side of the support frame 4. A clamping plate 6 is threadedly connected to the outer side of the threaded rod 5. A limiting rod 7 is slidably connected to the inner side of the clamping plate 6. The limiting rod 7 is fixedly connected to the support frame 4. A slider 8 is fixedly connected to the outer side of the support frame 4. A connecting frame 9 is slidably connected to the outer side of the slider 8. A hydraulic cylinder 10 is fixedly connected to the inner side of the base 1. The output end of the hydraulic cylinder 10 is fixedly connected to the connecting frame 9. This step, by setting up the rotating rod 2, rotating plate 3, support frame 4, slider 8, connecting frame 9, and hydraulic cylinder 10, allows for the placement of... When placing the rear frame, the hydraulic cylinder 10 drives the connecting frame 9 to move, which in turn pushes the support frame 4 to move. Simultaneously, the support frame 4 drives the rotating plate 3 to move and rotate. The rotation of the rotating plate 3 causes the support frame 4 to move downwards. When the support frame 4 reaches its lowest position, the frame is lifted and placed on the support frame 4. After placement, the positive and negative threaded screws 5 are rotated, causing the clamping plates 6 to move closer together to clamp and fix the rear frame. The hydraulic cylinder 10 drives the connecting frame 9 to move in the opposite direction, which in turn drives the slider 8 to move. This causes the slider 8 to pull the support frame 4 to move in the opposite direction, causing one end of the rotating plate 3 to rotate and rise. This causes the support frame 4 to lift the rear frame, making it easier to weld. This makes it easier to place the rear frame on the support frame 4, improving the ease of use of the device.

[0024] Furthermore, such as Figure 1As shown, an inclined plate 11 is fixedly connected to the outer side of the base 1, and a roller 12 is rotatably connected to the inner side of the inclined plate 11. This step, by setting the inclined plate 11 and the roller 12, allows the rear frame to be moved to the inclined surface near the inclined plate 11 after welding by the support frame 4. The clamp 6 is released, and the rear frame is pushed to slide down the inclined surface of the inclined plate 11. At the same time, the rear frame will first come into contact with the roller 12 to generate friction. The roller 12 rotates, making the sliding of the rear frame smoother, which facilitates its separation and removal from the device, thus improving the convenience of using the device.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, slots 13 are provided on the inner side of the base 1 and the inner side of the support frame 4. Insert rods 14 are slidably connected to the inner side of the slots 13, and a synchronization plate 15 is fixedly connected to the outer side of the insert rods 14. By setting up slots 13, insert rods 14 and synchronization plate 15, after the support frame 4 is rotated to the raised position, the synchronization plate 15 can be pushed to move. The synchronization plate 15 drives multiple insert rods 14 to be inserted into the slots 13 on the inner side of the base 1 or the support frame 4 respectively. The position of the insert rods 14 on the inner side of the base 1 is restricted, thereby further restricting the position of the synchronization plate 15. In turn, the synchronization plate 15 restricts the position of the insert rods 14 on the other side and the support frame 4, making the position of the support frame 4 more stable and improving the stability of the device.

[0026] Furthermore, such as Figure 1 As shown, a baffle 16 is fixedly connected to the outer side of the base 1. The baffle 16 and the rotating plate 3 are used together. By setting the baffle 16, when the rotating plate 3 rotates to the maximum position, the baffle 16 closes to the rotating plate 3 to restrict its position, making it difficult for the rotating plate 3 to continue to move. This makes it difficult for the hydraulic cylinder 10 to drive the rotating plate 3 to rotate excessively, thus improving the stability of the device.

[0027] Furthermore, such as Figure 1 and Figure 5 As shown, a limiting groove 17 is provided on the inner side of the base 1, and a limiting strip 18 is fixedly connected to the inner side of the limiting groove 17. The limiting strip 18 is fixedly connected to the connecting frame 9. This step, by setting the limiting groove 17 and the limiting strip 18, allows the limiting groove 17 to restrict the limiting strip 18 when the connecting frame 9 moves, thereby further restricting the movement trajectory of the connecting frame 9, making its movement more stable and less prone to shaking, and improving the stability of the device.

[0028] Furthermore, such as Figure 2As shown, a movable plate 19 is slidably connected to the inner side of the base 1. The movable plate 19 and the support frame 4 are used in conjunction. In this step, by setting the movable plate 19, when the support frame 4 moves to the highest position, a part of the movable plate 19 is inserted into the inner side of the base 1, so that one end of the movable plate 19 is close to the lower side of the support frame 4, thereby further restricting and supporting the position of the support frame 4, making its placement more stable and improving the stability of the device.

[0029] Working principle: When placing the rear frame, the hydraulic cylinder 10 drives the connecting frame 9 to move, which in turn pushes the support frame 4 to move. Simultaneously, the support frame 4 drives the rotating plate 3 to move and rotate. The rotation of the rotating plate 3 causes the support frame 4 to move downwards. When the support frame 4 reaches its lowest position, the frame is lifted and placed on the upper side of the support frame 4. After placement, the positive and negative threaded screws 5 are rotated, which causes the clamping plates 6 to move closer together, thereby clamping and fixing the rear frame. The hydraulic cylinder 10 drives the connecting frame 9 to move in the opposite direction, which in turn drives the slider 8 to move. This causes the slider 8 to pull the support frame 4 to move in the opposite direction, causing one end of the rotating plate 3 to rotate and rise. This causes the rotating plate 3 to push the support frame 4 to rise. The support frame 4 then drives the slider 8 to move upwards inside the connecting frame 9, supporting the support frame 4 and raising the rear frame to its highest position for welding.
