Description

Technical Field

[0001] This utility model relates to the field of shaft support technology, and in particular to a shaft welding rotary support frame. Background Technology

[0002] In the current spindle repair service industry, the welding and repair of spindle parts faces challenges due to difficulties in rotary welding of the spindle core and misalignment of the welding angle, which greatly hinders the welding work. The newly invented support frame, with its unique angle and support module, significantly simplifies the welding process.

[0003] The inventors believe that the following defects often exist: when workers weld and repair the shaft, the angle between the shaft and the base is small, making it inconvenient for workers to repair the damaged parts of the shaft, thus increasing the workload of workers and reducing work efficiency; therefore, a shaft core welding rotating support frame is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the small angle between the shaft and the base, which makes it inconvenient for workers to repair the damaged parts of the shaft, and to propose a shaft core welding rotating support frame.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shaft-welded rotating support frame, including a base, a first sliding plate slidably connected to the inner surface of the base, a second sliding plate slidably connected to the inner surface of the base, and a third sliding plate slidably connected to the inner surface of the base. A first fastening handle is threaded into the inner thread of the first sliding plate, a second fastening handle is threaded into the inner thread of the second sliding plate, and a third fastening handle is threaded into the inner thread of the third sliding plate. A front-end support frame is fixedly connected to the surface of the first sliding plate, a baffle is fixedly connected to one side of the third sliding plate, and a front-end V-shaped frame is slidably connected to one side of the front-end support frame. The surface of the second sliding plate is fixedly connected to... The device is equipped with a rear V-shaped frame. A steel ball is slidably connected to the inner surface of the baffle, and the steel ball is slidably connected to the surface of the base. A shaft is slidably connected to the surface of the front V-shaped frame. Two connecting blocks are fixedly connected to the side of the front V-shaped frame near the front support frame. Two sliding holes are opened on the surface of the front support frame. The surfaces of the two sliding holes of the front support frame are slidably connected to the two connecting blocks respectively. A fixing plate is fixedly connected to one side of the connecting block. A fixing rod is fixedly connected to the surface of the fixing plate. An operating plate is slidably connected to the arc surfaces of the two fixing rods. An insert plate is fixedly connected to one side of the operating plate. Several slots are opened on the surface of the front support frame.

[0006] The aforementioned components achieve the following effects: by adjusting the angle between the shaft and the base support, the difficulty of shaft welding repair is reduced, and shafts of different lengths and sizes are universally compatible. During the welding process, rotary welding can be completed more easily, avoiding the situation where the angle between the shaft and the base is too small when workers are welding and repairing the shaft, making it inconvenient for workers to repair the damaged parts of the shaft, thus increasing the workload of workers and reducing work efficiency, thereby improving the practicality of the device.

[0007] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insert plate is adapted to the size of the front support frame slot.

[0008] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.

[0009] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the fixing plate, respectively.

[0010] The effect achieved by the above components is that the first spring improves the stability of the insert plate when it limits the front V-shaped frame.

[0011] Preferably, two rubber rings are fixedly connected to the surface of the operating panel, and the two rubber rings are slidably connected to the arc surfaces of the two fixed rods respectively.

[0012] The effect achieved by the above components is to reduce the sliding speed of the control panel on the arc surface of the fixed rod, and at the same time reduce the shaking effect of the external environment on the control panel, thus achieving a damping effect.

[0013] Preferably, two support plates are fixedly connected to one side of the baffle, and a drive rod is threaded into the support plate. One end of the drive rod is rotatably connected to a clamping block.

[0014] The aforementioned components achieve the following effect: they limit and fix the steel ball, preventing displacement of the steel ball when the shaft slides on the arc surface of the steel ball, thus avoiding any impact on the correct positioning of the shaft and improving the stability of the device.

[0015] Preferably, an anti-slip pad is fixedly connected to one side of the clamping block, and the anti-slip pad abuts against the arc surface of the steel ball.

[0016] The effect achieved by the above components is that the anti-slip pad increases the friction between itself and the steel ball, thereby increasing the stability when holding the steel ball.

[0017] Preferably, a positioning rod is fixedly connected to one side of the clamping block, and the arc surface of the positioning rod is slidably connected to the support plate.

[0018] The effect achieved by the above components is that the positioning rod restricts the rotation of the clamping block, so as to provide stable and accurate guidance for the clamping block.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] This invention achieves the effect of reducing the difficulty of shaft welding repair by adjusting the angle between the shaft and the base support, and is applicable to shafts of different lengths and sizes. It also allows for easier rotational welding during the welding process, avoiding the situation where the angle between the shaft and the base is too small when workers are welding and repairing the shaft, making it inconvenient for workers to repair the damaged parts of the shaft, thus increasing the workload of workers and reducing work efficiency. This improves the practicality of the device. Attached Figure Description

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a shaft-core welded rotating support frame, including a base 1, a first sliding plate 2 slidably connected to the inner surface of the base 1, a second sliding plate 3 slidably connected to the inner surface of the base 1, a third sliding plate 4 slidably connected to the inner surface of the base 1, a first fastening handle 5 threaded into the inner thread of the first sliding plate 2, a second fastening handle 6 threaded into the inner thread of the second sliding plate 3, a third fastening handle 7 threaded into the inner thread of the third sliding plate 4, a front-end support frame 8 fixedly connected to the surface of the first sliding plate 2, a baffle 9 fixedly connected to one side of the third sliding plate 4, a front-end V-shaped frame 10 slidably connected to one side of the front-end support frame 8, a rear-end V-shaped frame 11 fixedly connected to the surface of the second sliding plate 3, and a steel ball 12 slidably connected to the inner surface of the baffle 9. The steel ball 12 is connected to the base 1. The surface of the base 1 is slidably connected, and the surface of the front V-shaped frame 10 is slidably connected to the shaft 13. Two connecting blocks 14 are fixedly connected to the side of the front V-shaped frame 10 near the front support frame 8. Two sliding holes are opened on the surface of the front support frame 8, and the surfaces of the two sliding holes of the front support frame 8 are slidably connected to the two connecting blocks 14 respectively. A fixing plate 15 is fixedly connected to one side of the connecting block 14, and a fixing rod 16 is fixedly connected to the surface of the fixing plate 15. An operating plate 17 is slidably connected to the arc surface of the two fixing rods 16. An insert plate 18 is fixedly connected to one side of the operating plate 17. Several slots are opened on the surface of the front support frame 8. When the operator needs to support the shaft 13, the shaft 13 is placed on the front V-shaped frame 10, and one end of the shaft 13 abuts against... On the arc surface of the steel ball 12, the rear V-shaped bracket 11 supports the middle part of the shaft 13. At this time, by releasing the first fastening handle 5, the second fastening handle 6, and the third fastening handle 7 from the base 1, the positions of the first sliding plate 2, the second sliding plate 3, and the third sliding plate 4 can be adjusted. Simultaneously, the operating plate 17 can be pulled, causing it to slide on the arc surface of the fixed rod 16. The operating plate 17 drives the insert plate 18 to move until the insert plate 18 disengages from the slot of the front support bracket 8, thereby adjusting the height of the front V-shaped bracket 10. At this time, one end of the shaft 13 slides on the arc surface of the steel ball 12, achieving the goal of reducing the difficulty of welding and repairing the shaft 13 by adjusting the angle between the shaft 13 and the base 1 bracket, and making it compatible with shafts 13 of different lengths and sizes during welding. The process allows for easier rotary welding, avoiding the inconvenience of repairing damaged areas of the shaft 13 when the angle between the shaft 13 and the base 1 is small, which would increase the workload and reduce efficiency. This improves the practicality of the device. One end of the fixed rod 16 is fixedly connected to a limiting plate 19. The size of the insert plate 18 matches the size of the slot in the front support frame 8. When the operator pulls the operating plate 17, it slides on the arc surface of the fixed rod 16. At this time, the limiting plate 19 limits the maximum sliding distance of the operating plate 17 on the arc surface of the fixed rod 16, preventing excessive pulling force when the operator pulls the operating plate 17.This can cause the operating plate 17 to detach from the arc surface of the fixing rod 16. A first spring 20 is fitted onto the arc surface of the fixing rod 16, with both ends of the first spring 20 fixedly connected to the operating plate 17 and the fixing plate 15, respectively. When the operator releases the operating plate 17, the rebound force of the first spring 20 causes the operating plate 17 to slide on the arc surface of the fixing rod 16. Simultaneously, the operating plate 17 moves the insert plate 18 until it inserts into the slot of the front support frame 8. At this point, the first spring 20 improves the stability of the insert plate 18 when it limits the front V-shaped frame 10. Two rubber rings 21 are fixedly connected to the surface, and the two rubber rings 21 are slidably connected to the arc surfaces of the two fixed rods 16 respectively. When the operator moves the operating plate 17, the elasticity of the rubber rings 21 wraps around the arc surfaces of the fixed rods 16, thereby reducing the sliding speed of the operating plate 17 on the arc surfaces of the fixed rods 16, and reducing the shaking effect of the external environment on the operating plate 17, thus achieving a damping effect. Two support plates 22 are fixedly connected to one side of the baffle 9. A drive rod 23 is threaded into the support plate 22, and a clamping block 24 is rotatably connected to one end of the drive rod 23. When the operator moves the operating plate 17, the operating plate 17 moves the operating plate 16. After placing the steel ball 12, rotate the drive rod 23. The drive rod 23 moves along the internal thread of the support plate 22, and at the same time, the drive rod 23 drives the clamping blocks 24 to move until the two clamping blocks 24 clamp the steel ball 12. At this point, the steel ball 12 is effectively limited and fixed, preventing displacement of the steel ball 12 when the shaft 13 slides on the arc surface of the steel ball 12, which would affect the correct positioning of the shaft 13 and improve the stability of the device. An anti-slip pad 25 is fixedly connected to one side of the clamping block 24. The anti-slip pad 25 abuts against the arc surface of the steel ball 12. This increases the friction between the clamping block 24 and the steel ball 12, thereby improving stability when holding the ball. A positioning rod 26 is fixedly connected to one side of the clamping block 24. The arc surface of the positioning rod 26 is slidably connected to the support plate 22. When the operator rotates the drive rod 23, the drive rod 23 moves threadedly within the support plate 22, simultaneously driving the clamping block 24 to move. The clamping block 24 then causes the positioning rod 26 to slide within the support plate 22. In this state, the positioning rod 26 restricts the rotation of the clamping block 24, providing stable and accurate guidance.

[0028] Working principle: When welding repair is required on the shaft 13, the shaft 13 is first placed on the front V-shaped bracket 10, with one end abutting against the arc surface of the steel ball 12. The rear V-shaped bracket 11 provides support for the middle of the shaft 13. By loosening the first fastening handle 5, the second fastening handle 6, and the third fastening handle 7, the contact with the base 1 is released, and the positions of the first sliding plate 2, the second sliding plate 3, and the third sliding plate 4 can be adjusted, thereby changing the relative positions of the front V-shaped bracket 10, the rear V-shaped bracket 11, and the baffle 9 to accommodate shafts 13 of different lengths. If the height of the front V-shaped bracket 10 needs to be adjusted, the operating plate 17 is pulled, causing it to slide on the arc surface of the fixing rod 16. The operating plate 17 drives the insert plate 18 to disengage from the slot of the front support frame 8. After the height adjustment is completed, the operating plate 17 is released, and the first spring 20 on the fixing rod 16 releases its rebound force, causing the operating plate 17 and the insert plate 18 to return to their original positions. Positioning the insert plate 18 back into the slot, fixing the position of the front V-shaped bracket 10. During this process, the rubber ring 21 on the surface of the operating plate 17 contacts the fixing rod 16, slowing down the sliding speed of the operating plate 17 and reducing the impact of external shaking. After adjusting the position and angle of the shaft 13, rotate the drive rod 23. The drive rod 23 moves in the thread of the support plate 22, driving the clamping block 24 to move until the two clamping blocks 24 firmly clamp the steel ball 12 through the anti-slip pad 25 on them, preventing the steel ball 12 from being displaced when the shaft 13 slides. The positioning rod 26 restricts the rotation of the clamping block 24 during its movement, ensuring that the clamping process is stable and accurate. At this time, the shaft 13 can rotate flexibly on the arc surface of the steel ball 12. The operator can reduce the difficulty of welding repair by adjusting the angle between the shaft 13 and the base 1, and easily complete the rotation welding of the shaft 13 during the welding process, improving work efficiency and the practicality of the device.
