[0003] Existing intermediate shaft assembly phase fixtures mostly utilize fixed or semi-fixed mechanical structures. These fixtures typically consist of a rigid base, fixed stoppers, and a single adjustment component. Their technical principles primarily rely on pre-set mechanical positioning points and a limited adjustment range. The intermediate shaft assembly is placed on the fixed stoppers and initially secured using simple fasteners such as bolts and nuts. Phase calibration is then achieved through manual measurement and fine-tuning. However, this structure often requires repeated disassembly and reassembly of components during adjustment, resulting in a cumbersome operation.

[0004] However, existing intermediate shaft assembly phase fixtures, due to their fixed structure and limited adjustment methods, are difficult to quickly adapt to intermediate shaft assemblies of varying specifications and models, and cannot be quickly adjusted in complex and ever-changing work scenarios. Furthermore, the overall structure is relatively bulky, making it difficult to transport and store. This results in low production efficiency and insufficient flexibility, making the fixtures unable to meet the efficient and convenient production needs of modern manufacturing. Summary of the Invention

[0018] The following is combined with Figure 1 - Attachment Figure 3 , the present invention is described in further detail.

[0019] The present invention provides a portable intermediate shaft assembly phase fixture structure, including a base plate 1, a slide groove on the surface of which provides a track for the left and right sliding of components such as the V-block support 2 and the front support plate 6 to achieve distance adjustment; the anti-slip material of the outer wall cooperates with the clamping block 24 to enhance the friction during fixation and ensure the overall stability of the fixture, and the upper surface of the base plate 1 is slidably connected to two V-block supports 2 and two front support plates 6, the V-block support 2: supports the V-block 3, and realizes left and right sliding through the slide groove of the base plate 1, and cooperates with the nut 5 to adjust the height of the V-block 3 to meet the positioning requirements of intermediate shaft assemblies of different specifications, and a V-block 3 is provided above the two V-block supports 2, the V-block 3: is used to support the intermediate shaft assembly, and its V-groove structure can accurately locate the central axis of the shaft parts to ensure that the intermediate shaft is in a horizontal state, the interior of the V-block 3 is provided with an up and down adjustment component, and the interior of the two front support plates 6 is provided with an angle adjustment component; The up and down adjustment assembly includes two threaded pins 4 and two nuts 5. By adjusting the nuts 5 up and down, the height of the V-block 3 can be changed to keep the intermediate shaft horizontal, while ensuring that the slot of the yoke is in the correct matching position with the front bracket 8 to achieve precise positioning. The outer walls of the two are both set through the interior of the V-block 3, and the bottom is fixedly connected to the interior of the V-block support 2. The two nuts 5 are respectively threadedly connected to the two threaded pins 4 and rotatably connected to the interior of the V-block 3; The angle adjustment assembly includes two rotating shafts 10 and two V-block supports 2. The outer walls of the two rotating shafts 10 are rotatably connected to the inside of the two front support plates 6 respectively. The front support plate 6 and the V-block support 2 slide left and right in the slide groove of the base plate 1 together, which is used to adjust the distance between the front bracket 8 and the V-block 3 to adapt to the length change of the intermediate shaft assembly and improve the versatility of the fixture. The thread on the outer wall of the bolt 12 matches the preset thread inside the rotating shaft 10 and is threadedly connected. A gasket 11 is provided between the screw head part of the bolt 12 and the front support plate 6. One end of one of the rotating shafts 10 is fixedly connected to the vertical plate clamp 9, and one end of the other rotating shaft 10 is fixedly connected to the front pin 7. The front pin 7 is inserted into the slot of the yoke to realize the initial positioning of the intermediate shaft assembly, ensuring that there is no interference when pushing the intermediate shaft, and ensuring assembly accuracy. The outer wall of the vertical plate clamp 9 is fixedly connected to the front bracket 8. The front bracket 8 is fixed on the base plate 1, and its structure cooperates with the slot of the yoke to provide an insertion guide for the front pin 7. The positioning direction can be adjusted by rotating the front bracket 8 to adapt to different phase requirements.

[0020] Specifically, when using this fixture structure, first place the intermediate shaft assembly on the V-block 3. Adjust the nut 5 to keep the intermediate shaft horizontal, while also positioning the yoke in a specified horizontal position, with its slot aligned with the front bracket 8. Push the intermediate shaft until the front pin 7 smoothly inserts into the yoke slot, ensuring no interference. During this process, the positioning direction can be adjusted by rotating the front bracket 8 and front pin 7, and the height of the V-block 3 can be adjusted using the nut 5. The V-block support 2 and front support plate 6 can slide left and right within the slots of the base plate 1, allowing for flexible adjustment of the distance between components to accommodate intermediate shaft assemblies of varying specifications.

[0021] Please see the attached Figure 3 - Attachment Figure 5 The two front support plates 6 and the lower surfaces of the two V-shaped block supports 2 are fixedly connected with a mounting plate 13. The mounting plate 13 serves as a mounting carrier of the fixing mechanism, carrying components such as the handle 17 and the slider 16, and cooperates with the positioning block 14 to realize the positioning of the overall fixed structure. A locking component is provided inside the mounting plate 13.

[0022] Please see the attached Figure 3 - Attachment Figure 5 The locking assembly includes a fixing sleeve 15 and a U-shaped slide groove 19. The lower surface of the mounting plate 13 is fixedly connected with a positioning block 14. The positioning block 14: accurately positions the mounting plate 13 to ensure that the installation position of the fixing mechanism is accurate and provides a reference for subsequent locking operations. The inner wall of the fixing sleeve 15 is slidably connected with a slider 16. The upper surface of the slider 16 is fixedly connected with a handle 17. The handle 17: serves as the operating end. Pressing the handle 17 can drive the slider 16 to slide in the fixing sleeve 15, and the action of the locking mechanism is realized through mechanical linkage; rotating the handle 17 can change the position of the limit block 18 to complete the locking or releasing operation. The outer wall of the slider 16 is fixedly connected with the limit block 18. The limit block 18: slides in the U-shaped slide groove 19 and limits the slider 16 by position change. After releasing the handle 17, the spring 21 rebounds and drives the limit block 18 to engage the other end slide of the U-shaped slide groove 19 to prevent the slider 16 from moving, thereby achieving a locked state of the fixture. The lower surface of the slider 16 is fixedly connected with a slide rod 20, which connects the handle 17 and the turntable 22. When the handle 17 is turned, the slide rod 20 is driven to rotate, thereby driving the turntable 22 to slide in the positioning block 14. The outer wall of the slide rod 20 is provided with a spring 21, and one end of the spring 21 is fixedly connected to a support plate 25, which fits the slider 16. The slider 16: When sliding on the inner wall of the fixed sleeve 15, it drives the limit block 18 to move, thereby compressing the spring 21, and the outer wall of the slide rod 20 is provided with a fixed component.

[0023] Please see the attached Figure 3 - Attachment Figure 5The fixed component includes a turntable 22, and the turntable 22: the arc-shaped slide groove 23 inside the turntable 22 cooperates with the block 24. When the turntable 22 rotates, the track of the arc-shaped slide groove 23 drives the block 24 to slide, so that the block 24 is tightly fitted or separated from the bottom plate 1. The inner part of the turntable 22 is slidably connected to the outer wall of the slide rod 20. The inner part of the turntable 22 is provided with an arc-shaped slide groove 23. The inner part of the turntable 22 is slidably connected to the block 24. The outer wall of the block 24 is slidably connected to the inner part of the positioning block 14, and the outer wall of the limit block 18 is slidably connected to the inner part of the U-shaped slide groove 19. The spring One end of 21 is fixedly connected to the inner wall of the fixed sleeve 15, and the outer wall of the fixed sleeve 15 is slidably connected to the inside of the mounting plate 13. A U-shaped slide groove 19 is opened inside the fixed sleeve 15, and a slide groove for sliding the mounting plate 13 is opened inside the base plate 1. The position of the slide groove is in contact with the block 24, and slides to the inside of the base plate 1 under the drive of the turntable 22, and cooperates with the anti-slip material of the outer wall of the base plate 1. The V-block support 2, the front support plate 6 and other components are fixed to the base plate 1 through friction to prevent the adjusted position from shifting. The end of the block 24 is made of anti-slip material.

[0024] Specifically, after accurately positioning the mounting plate 13 using the positioning block 14, the handle 17 is pressed, driving the slider 16 to slide along the inner wall of the fixing sleeve 15. The movement of the slider 16 further drives the limit block 18 to slide within the U-shaped groove 19 inside the fixing sleeve 15, causing the spring 21 to contract. The handle 17 is then turned, causing the limit block 18 to slide to the other end within the U-shaped groove 19. Simultaneously, the slide bar 20 rotates, driving the turntable 22 to slide within the positioning block 14. The arc-shaped groove 23 inside the turntable 22 drives the clamping block 24 to slide, making it fit tightly against the base plate 1. Combined with the anti-slip material on the outer wall of the base plate 1, this achieves a secure fixation of the V-block support 2 and the front support plate 6. After the installation is completed and the handle 17 is released, the spring 21 rebounds, driving the limit block 18 to move to the slideway on the other side of the U-shaped slide 19 for limiting, completing the locking operation, ensuring that the fixture is stable and reliable during use, effectively avoiding positioning deviations caused by loose components, and ensuring high precision and reliability of the phase adjustment of the intermediate shaft assembly.

[0025] Working principle: When using this fixture structure, first place the intermediate shaft assembly on the V-block 3 and adjust the nut 5 up and down to make the intermediate shaft horizontal and the yoke in the horizontal position shown in the figure. The slot is matched with the front bracket 8. Push the intermediate shaft so that the front pin 7 is inserted into the yoke slot. There is no interference in the whole process. During this process, the front bracket 8 and the front pin 7 are rotated to locate the direction. The height of the V-block 3 is adjusted by the nut 5, and the V-block support 2 and the front support plate 6 can slide left and right in the slide groove of the bottom plate 1 to achieve adjustable distance. In addition, the mounting plate 13 is placed in the designated position by positioning the positioning block 14, and then the handle 17 is pressed, thereby driving the slider 16 to slide on the inner wall of the fixing sleeve 15. At the same time, the movement of the slider 16 drives the limit block 18 to slide in the U-shaped slide groove 19 inside the fixing sleeve 15, thereby causing the spring 21 to contract, and then the handle 17 is turned to drive the limit block 18 to slide inside the U-shaped slide groove 19, thereby sliding the limit block 18 to the other end of the U-shaped slide groove 19, and at the same time, by rotating the slide rod 20 The turntable 22 is driven to slide inside the positioning block 14, and then the block 24 is driven to slide through the arc-shaped slide groove 23 inside the turntable 22, so that the block 24 is tightly fitted with the base plate 1, and the anti-slip material of the outer wall of the base plate 1 enables it to be stably fitted and fixed on the inner side of the base plate 1, thereby fixing the upper V-shaped block support 2 and the front support plate 6. After installation, the handle 17 is released, and the spring 21 is no longer subjected to force and rebounds, driving the limit block 18 to move to the slideway on the other side of the U-shaped slide groove 19 for limiting, thereby achieving locking.

[0026] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
