Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to a rotating support frame for welding bearing seats. Background Technology

[0002] In the spindle repair service industry and in various jobs involving bearing housing welding, spare parts are often repaired by welding in order to improve the timeliness of spindle repair.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Traditional welding support equipment suffers from numerous inconveniences when dealing with large or heavy circular workpieces. On the one hand, rotating circular workpieces often involves considerable effort, which not only increases the labor intensity of operators but also reduces work efficiency. On the other hand, uneven speed control makes it difficult to ensure the welding angle is correct, resulting in inconsistent welding quality and posing significant challenges to the welding process. Furthermore, some existing welding support equipment also has shortcomings in angle adjustment and workpiece positioning, failing to meet complex welding requirements. Therefore, to address the above problems, a bearing housing welding rotary support frame is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of traditional welding support equipment in the prior art when facing large or heavy circular workpieces, such as laborious rotation, uneven speed control, and difficulty in ensuring welding angle. These problems not only increase labor intensity and reduce efficiency, but also affect welding quality. At the same time, they are also difficult to meet the complex welding requirements in terms of angle adjustment and workpiece positioning. Therefore, the proposed bearing seat welding rotary support frame is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bearing seat welded rotating support frame, including a fixed seat, a base plate rotatably connected to the upper surface of the fixed seat, a turntable base fixedly connected to the upper surface of the base plate, two radial steel balls fixedly connected to the upper surface of the turntable base, several axial steel balls fixedly connected to the upper surface of the turntable base, a turntable body slidably connected to the arc surfaces of the radial and axial steel balls, three first sliding grooves opened on the upper surface of the turntable body, positioning blocks slidably connected to the inner walls of the first sliding grooves, threaded rods inserted into the internal threads of the positioning blocks, the threaded rods abutting against the bottom of the inner walls of the first sliding grooves, second sliding grooves opened on both sides of the fixed seat, sliders slidably connected to the inner walls of the two second sliding grooves, a support angle adjustment block fixedly connected to the upper surface of the sliders, several circular grooves opened on one side of the fixed seat, a circular rod fixedly connected to one side of the sliders, an arc-shaped block slidably connected to the arc surface of the circular rod, an insert rod fixedly connected to the surface of the arc-shaped block, and the insert rod slidably connected to the inner wall of the circular groove.

[0006] The effects achieved by the above components are as follows: by setting radial and axial steel balls, the turntable body can rotate smoothly; the cooperation of the positioning block, threaded rod and first slide groove can facilitate the fixed positioning of workpieces of different sizes; at the same time, the combination of slider, support angle adjustment block and circular groove, insertion rod and other structures can flexibly adjust the angle during support, so that it has the function of multi-angle flexible adjustment and precise positioning during support, which can effectively improve the operational convenience and accuracy of bearing seat welding.

[0007] Preferably, the arc surface of the support angle adjustment block is fixedly connected to an anti-slip pad, which is made of silicone rubber.

[0008] The effects achieved by the above components are as follows: silicone rubber has good anti-slip and wear resistance, which can increase the friction with the contact parts, prevent slippage and displacement during angle adjustment and welding, ensure support stability, and improve the safety and accuracy of welding operations.

[0009] Preferably, a stop block is fixedly connected to one end of the round rod.

[0010] The effect achieved by the above components is as follows: a stop is set at one end of the round rod to prevent the arc block from sliding excessively on the round rod and disengaging, thus playing a limiting role, ensuring that the insertion rod and the round groove are properly matched, and maintaining the stability and reliability of the support angle adjustment structure.

[0011] Preferably, a spring is fitted onto the arc surface of the round rod, and the two ends of the spring are fixedly connected to the arc block and the stop block, respectively.

[0012] The effect achieved by the above components is that when the insertion rod is aligned with the circular groove, the spring force can drive the insertion rod to automatically insert into the inner wall of the circular groove, which improves the convenience of adjusting the angle.

[0013] Preferably, a connecting plate is fixedly connected to one side of the slider, and the surface of the connecting plate is provided with anti-slip protrusions.

[0014] The effect achieved by the above components is that the connecting plate fixedly connected to one side of the slider provides the operator with a convenient point of force application. When adjusting the position of the slider to change the support angle, it can be achieved by directly pushing and pulling the connecting plate, which makes it easier to apply force and control.

[0015] Preferably, a screw is fixedly connected to one side of the slider, and an arc-shaped plate is threadedly connected to the arc surface of the screw.

[0016] The effect achieved by the above components is that the arc plate restricts the movement trajectory of the arc block, avoiding the situation where the plug rod moves forward continuously due to the influence of the spring during the sliding process of pushing the slider, and will continuously rub against one side of the fixed seat and be damaged, thus extending the service life of the components.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, by setting radial and axial steel balls, the turntable body can rotate smoothly. The cooperation of the positioning block, threaded rod, and first slide groove can facilitate the fixed positioning of workpieces of different sizes. At the same time, the combination of slider, support angle adjustment block, circular groove, and insert rod can flexibly adjust the angle during support, so that it has the function of multi-angle flexible adjustment and precise positioning during support, which can effectively improve the operational convenience and accuracy of bearing seat welding.

[0024] Reference Figures 1-4As shown, this utility model provides a technical solution: a bearing seat welded rotating support frame, including a fixed seat 7, a base plate 8 rotatably connected to the upper surface of the fixed seat 7, a turntable base 5 fixedly connected to the upper surface of the base plate 8, two radial steel balls 3 fixedly connected to the upper surface of the turntable base 5, and several axial steel balls 4 fixedly connected to the upper surface of the turntable base 5. A turntable body 1 is slidably connected to the arc surfaces of the radial steel balls 3 and the axial steel balls 4. Three first sliding grooves 9 are formed on the upper surface of the turntable body 1. A positioning block 2 is slidably connected to the inner wall of the first sliding groove 9. A threaded rod 10 is threaded into the positioning block 2, and the threaded rod 10 abuts against the bottom of the inner wall of the first sliding groove 9. Second sliding grooves 11 are formed on both sides of the fixed seat 7, and sliders are slidably connected to the inner walls of the two second sliding grooves 11. 12. A support angle adjustment block 6 is fixedly connected to the upper surface of the slider 12. Several circular grooves 13 are opened on one side of the fixed seat 7. A circular rod 14 is fixedly connected to one side of the slider 12. An arc-shaped block 15 is slidably connected to the arc surface of the circular rod 14. An insert rod 16 is fixedly connected to the surface of the arc block 15. The insert rod 16 is slidably connected to the inner wall of the circular groove 13. By setting radial steel balls 3 and axial steel balls 4, the turntable body 1 can rotate smoothly. The cooperation of the positioning block 2, the threaded rod 10 and the first sliding groove 9 can facilitate the fixed positioning of workpieces of different sizes. At the same time, the combination of the slider 12, the support angle adjustment block 6, the circular groove 13, the insert rod 16 and other structures can flexibly adjust the angle during support, so that it has the functions of multi-angle flexible adjustment and precise positioning during support. This design effectively improves the ease and precision of operation during bearing housing welding. The arc surface of the support angle adjustment block 6 is fixedly connected to an anti-slip pad 22, which is made of silicone rubber. Silicone rubber has excellent anti-slip and wear-resistant properties, increasing friction with contacting parts and preventing slippage or displacement during angle adjustment and welding. This ensures support stability and enhances the safety and precision of welding operations. One end of the round rod 14 is fixedly connected to a stop, and a stop block 17 is provided at one end of the round rod 14 to prevent the arc block 15 from sliding excessively on the round rod 14 and disengaging, thus limiting its movement and ensuring proper engagement between the insert rod 16 and the circular groove 13. This maintains the stability and reliability of the support angle adjustment structure. A spring 18 is fitted onto the arc surface of the round rod 14, with both ends of the spring 18 connected to the arc block 16. 5 and stop 17 are fixedly connected. When the insertion rod 16 is aligned with the circular groove 13, the elastic force of the spring 18 can drive the insertion rod 16 to automatically insert into the inner wall of the circular groove 13, improving the convenience of adjusting the angle. A connecting plate 19 is fixedly connected to one side of the slider 12. The surface of the connecting plate 19 is provided with anti-slip protrusions. The connecting plate 19 fixedly connected to one side of the slider 12 provides the operator with a convenient point of force application. When adjusting the position of the slider 12 to change the support angle, it can be achieved by directly pushing and pulling the connecting plate 19, which is more convenient for force application and control. A screw 20 is fixedly connected to one side of the slider 12. The arc surface of the screw 20 is threadedly connected to an arc plate 21. The arc plate 21 restricts the movement trajectory of the arc block 15, preventing the slider 12 from sliding during the process.The insertion rod 16, influenced by the spring 18, moves continuously forward, causing it to rub against one side of the fixing seat 7, which could lead to damage. This process extends the service life of the components.

[0025] In terms of working principle, for workpiece positioning, the positioning block 2 can be pushed to slide within the first slide groove 9 according to the size of the workpiece. When the positioning block 2 abuts against the workpiece and precisely matches the workpiece contour, the threaded rod 10 is rotated to make it press against the bottom of the inner wall of the first slide groove 9. At this time, the positioning block 2 is firmly fixed, thereby stably constraining the workpiece on the turntable body 1. Regarding workpiece rotation, the radial steel ball 3 and the axial steel ball 4 constitute the rolling support structure of the turntable body 1, converting sliding friction into rolling friction, greatly reducing the resistance when the turntable body 1 rotates. Even with large and heavy circular workpieces, the operator can easily rotate the turntable body 1 to achieve smooth rotation operation. For angle adjustment, pushing the connecting plate 19 causes the slider 12 to slide freely within the second slide groove 11 of the fixed seat 7, moving the upper support angle adjustment block 6. Subsequently, the base plate 8 rotates upward, causing the turntable base 5 and the turntable body 1 to rotate upward. Once a suitable angle is found, rotating the arc plate 21 releases the restriction on the arc block 15. Then, the elastic force of the spring 18 causes the arc plate 21 to move forward, thereby causing the insertion rod 16 to automatically insert into the appropriate circular groove 13. At the same time, the silicone rubber anti-slip pad 22 on the arc surface of the support angle adjustment block 6, with its good anti-slip and wear resistance, increases the friction with the workpiece or other contact parts, preventing slippage and displacement during angle adjustment and welding.
