Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a flywheel bolt tightening machine alignment fixture. Background Technology

[0002] In the entire process of flywheel production and assembly, bolt tightening is a key link connecting the flywheel with core components such as the engine crankshaft and clutch. The quality of this operation directly determines the stability and operational safety of the entire machine's power transmission. It is a core process to ensure that the flywheel and related components form a reliable rigid connection or flexible transmission relationship.

[0003] Currently, traditional flywheel bolt tightening operations often rely on manual adjustment or simple tooling for flywheel positioning and clamping, which has the following shortcomings: Firstly, manual adjustment depends on the operator's experience, making it difficult to guarantee the alignment accuracy of flywheels of different sizes. This can easily lead to inconsistent bolt tightening torque due to clamping misalignment, affecting assembly quality. Secondly, existing tooling is mostly of fixed size or requires adjustment of multiple clamping structures separately, making it impossible to achieve synchronous opening and closing of the clamping frame. When adapting to flywheels of different specifications, the adjustment time is long, resulting in low work efficiency. Furthermore, the clamping structure lacks a stable guiding and transmission design, making it prone to movement jamming or misalignment, leading to insufficient clamping stability and affecting the continuity and reliability of bolt tightening operations. Therefore, there is an urgent need for a bolt tightening machine alignment fixture that can achieve precise alignment, stable clamping, and efficient adaptation to flywheels of different sizes to solve the above-mentioned problems in the existing technology.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a flywheel bolt tightening machine alignment fixture, including a base frame plate 1, a fixing plate 2 fixedly connected to the surface of the base frame plate 1, an upper sliding groove 3 and a lower sliding groove 4 respectively opened on the upper and lower surfaces of the fixing plate 2, an upper clamping bracket 5 slidably connected to the inner wall of the upper sliding groove 3, a lower clamping bracket 6 slidably connected to the inner wall of the lower sliding groove 4, an upper rotating plate 7 and a lower rotating plate 8 respectively arranged above and below the fixing plate 2, an upper pushing groove 11 opened on the surface of the upper rotating plate 7, and the upper pushing groove... The inner wall of 11 is slidably connected to the upper end of the upper clamping frame 5. The surface of the lower rotating plate 8 is provided with a lower pushing groove 12. The inner wall of the lower pushing groove 12 is slidably connected to the lower end of the lower clamping frame 6. The upper clamping frame 5 and the lower clamping frame 6 slide along the upper sliding groove 3 and the lower sliding groove 4 respectively. With the upper pushing groove 11 of the upper rotating plate 7 and the lower pushing groove 12 of the lower rotating plate 8, the clamping frame can be driven to open and close synchronously by the angle change of the rotating plate, quickly adapting to flywheels of different sizes, achieving precise alignment, and reducing manual adjustment time.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: the number of upper sliding grooves 3 and lower sliding grooves 4 are both set in two groups, and the two groups of upper sliding grooves 3 and lower sliding grooves 4 are symmetrically distributed. The surfaces of the upper rotating plate 7 and the lower rotating plate 8 are both provided with guide grooves 9. The guide grooves 9 are slidably connected to guide blocks 10. The guide blocks 10 are fixedly connected to the surface of the fixed plate 2. By setting two sets of symmetrically distributed upper and lower sliding grooves 4 and clamping brackets, the flywheel can be clamped from both sides at the same time to ensure uniform force and avoid clamping deviation affecting the bolt tightening accuracy. At the same time, the cooperation between the guide grooves 9 and the guide blocks 10 restricts the movement trajectory of the rotating plate and prevents it from deviating, further improving the structural stability.

[0026] Reference Figure 1 and Figure 4 As shown, specifically, a drive frame 13 is fixedly connected to one side of the bottom frame plate 1. A screw frame 17 is rotatably connected to the inner wall of the drive frame 13. A sliding frame 16 is threadedly connected to the surface of the screw frame 17. An upper push rod 14 and a lower push rod 15 are rotatably connected to the top of the sliding frame 16. One end of the upper push rod 14 is rotatably connected to the surface of the upper rotating plate 7, and one end of the lower push rod 15 is rotatably connected to the surface of the lower rotating plate 8. Moving grooves 18 are provided on both sides of the inner wall of the drive frame 13. The moving grooves 18 are slidably connected to the lower end of the sliding frame 16. An upper cover plate 19 is provided above the upper rotating plate. The upper cover plate 19 is fixedly connected to the top of the bottom frame plate 1 by bolts. By utilizing the drive frame 1... The screw frame 17, which is rotatably connected to the inner wall, forms a threaded engagement with the sliding frame 16. Combined with the moving grooves 18 opened on both sides of the inner wall of the drive frame 13, the lower end of the sliding frame 16 is limited and guided, so that the sliding frame 16 can move stably along the drive frame 13. At the same time, the upper push rod 14 and the lower push rod 15, which are rotatably connected to the top of the sliding frame 16, are rotatably connected to the surfaces of the upper rotating plate 7 and the lower rotating plate 8, respectively, so that the linear motion of the sliding frame 16 is converted into the angle change of the rotating plate. Then, the corresponding snap-fit ​​frame is driven to open and close synchronously along the sliding groove of the fixed plate 2 through the pushing groove on the surface of the rotating plate. With the help of the upper cover plate 19, the upper structure is protected and reinforced, and finally the flywheel is accurately aligned and stably clamped.

[0027] Working principle: During use, two sets of symmetrically distributed upper and lower sliding grooves 4 are formed on the fixed plate 2, which is fixed by the bottom frame plate 1. These grooves form sliding guides with the upper clamping frame 5 and the lower clamping frame 6, respectively. Combined with the upper and lower rotating plates 8 above and below the fixed plate 2 and the pushing grooves on their surfaces, they slide and connect with the ends of the clamping frames. The angle change of the rotating plates drives the clamping frames to open and close synchronously, quickly adapting to flywheels of different sizes, greatly reducing manual adjustment time, and achieving precise alignment. The two sets of symmetrically distributed clamping structures clamp the flywheels synchronously from both sides, ensuring uniform force and effectively avoiding the impact of clamping deviation on the bolt tightening accuracy. Simultaneously, the guide groove 9 on the surface of the rotating plate slides with the guide block 10 on the fixed plate 2, strictly limiting the movement trajectory of the rotating plate and preventing deviation to improve structural stability; the screw frame 17 inside the drive frame 13 is threadedly engaged with the sliding frame 16, and the moving groove 18 limits and guides the sliding frame 16, realizing the stable movement of the sliding frame 16. Then, the linear motion is converted into the angle change of the rotating plate through the upper and lower push rods 15, forming an efficient and stable transmission chain, ensuring smooth movement of the clamping frame and consistent clamping force. The protective reinforcement of the upper cover plate 19 further enhances the overall rigidity and reduces the impact of operational vibration.
