[0037] Embodiment

[0038] Refer to Figure 1-3 As shown in the figure, a kind of clutch intermediate shaft 5 tool fixture, including base 1, two support frames 2 connected with the base 1, setting in two the turnover mechanism 3 of support frame 2, and with the fixed assembly 4 connected with the turnover mechanism 3.

[0039] It can be understood that C clutch intermediate shaft 5 is a part of automobile clutch, which is a cylindrical shaft body with a through hole arranged inside, and a plurality of mounting holes are formed on the shaft body.

[0040] The base 1 is a flat plate mechanism, i.e. the surface of the base 1 is flat, to improve the overall structural stability, so as to improve the precision of clutch intermediate shaft 5 drilling processing. Two support frames 2 are arranged at the top end of the base 1, i.e. the bottom end of two support frames 2 is fixedly connected with the top end of the base 1 by threaded bolt, to realize the purpose of quick disassembly, wherein two support frames 2 are separately arranged on the base 1, i.e. there is a gap between two support frames 2. The turnover mechanism 3 is arranged between two support frames 2, and the two ends of the turnover mechanism 3 are rotatably connected with two support frames 2, so that the turnover mechanism 3 rotates between two support frames 2. The fixed assembly 4 is arranged at one end of the turnover mechanism 3, and the fixed assembly 4 is fixedly connected with the turnover mechanism 3, and the fixed assembly 4 is used for clamping and fixing the clutch intermediate shaft 5.

[0041] In this embodiment, the flip mechanism 3 includes a rotation shaft 31, a fixed protrusion 33, and a limit block 32. Specifically, the rotation shaft 31 is disposed between the two support frames 2, wherein each support frame 2 is provided with a through hole, and both ends of the rotation shaft 31 are respectively disposed in the holes on the two support frames 2, so that the rotation shaft 31 rotates on the support frames 2. In addition, one end of the rotation shaft 31 is fixedly connected to the fixed assembly 4, so that when the rotation shaft 31 rotates, the fixed assembly 4 can rotate by the same angle. The limit block 32 is fixedly arranged on the top of the base 1, and the limit block 32 is located between the two support frames 2. An arc groove adapted to the rotating shaft 31 is opened on the limit block 32. The arc groove has a semicircular structure, and the notch of the arc groove fits the rotating shaft 31. The groove edges at the upper and lower ends of the arc groove are parallel to the central axis of the rotating shaft 31, that is, the end face of the limit block 32 close to the rotating shaft 31 is on the same vertical plane as the central axis of the rotating shaft 31. The fixing protrusion 33 is arranged on the rotating surface of the rotating shaft 31 that fits with the limit block 32. The fixing protrusion 33 is adapted to the limit block 32, and the limit block 32 is also provided with a groove 321 adapted to the fixing protrusion 33. The notch diameter of the groove 321 is adapted to the cross-sectional diameter of the fixing protrusion 33, so that when the fixing protrusion 33 abuts against the limit block 32, the axis center of the limit protrusion is located directly above or below the rotating shaft 31, that is, under the action of the fixing protrusion 33 and the limit block 32, the rotation angle of the rotating shaft 31 is 180°, thereby improving the accuracy of the rotation angle of the rotating shaft 31.

[0042] In this embodiment, when drilling a hole in the clutch intermediate shaft 5 is required, the turning mechanism 3 is rotated, causing the rotating shaft 31 to rotate and drive the fixing protrusion 33 to abut against the stop block 32. The clutch intermediate shaft 5 is then sleeved on the fixing assembly 4, and the drilling position is adjusted before being fixed. At this point, the intermediate shaft is drilled for the first time. After the first drilling is completed, the turning mechanism 3 is rotated again, causing the rotating shaft 31 to rotate and drive the fixing protrusion 33 to rotate until the other end of the stop block 32 abuts again. At this point, the rotating shaft 31 has rotated 180°, and the intermediate shaft is drilled again. This ensures that the centers of the two drilled holes are aligned, ensuring the accuracy of the two drilled holes. This solves the problem of being unable to confirm the flip angle after manually flipping the clutch intermediate shaft 5, enables accurate control of the drilling accuracy of the clutch intermediate shaft 5 in mass production, and improves production efficiency.

[0043] In this embodiment, the fixing assembly 4 includes a mounting shaft 41, an end cap 42, and a positioning block 43. The mounting shaft 41 is fixedly connected to one end of the rotating shaft 31 and is located on one side of the support frame 2. The mounting shaft 41 is compatible with the clutch intermediate shaft 5, that is, the shape and size of the mounting shaft 41 are compatible with the shape and size of the clutch intermediate shaft 5. When the clutch intermediate shaft 5 is sleeved on the mounting shaft 41, the mounting shaft 41 and the clutch intermediate shaft 5 fit more closely, providing greater support and friction for the clutch intermediate shaft 5, and ensuring that the clutch intermediate shaft 5 is stably mounted on the mounting shaft 41. The end cap 42 is arranged on the end of the mounting shaft 41 away from the support frame 2. The end cap 42 is connected to the mounting shaft 41 by a thread. The threaded connection is self-locking and is a detachable connection method to improve work efficiency. When the clutch intermediate shaft 5 is installed on the mounting shaft 41, the end cap 42 is fixedly installed on the mounting shaft 41, and the clutch intermediate shaft 5 is squeezed to lock it on the mounting shaft 41 to prevent the clutch intermediate shaft 5 from offsetting during drilling. When the rotating shaft 31 rotates, the clutch intermediate shaft 5 fixed on the mounting shaft 41 rotates by the same angle. The positioning block 43 is provided on the base. The positioning block 43 is used to prevent the end cap 42 from rotating together with the clutch intermediate shaft 5 due to the friction of the end cap 42 when fixing the clutch intermediate shaft 5. The positioning block 43 is detachably connected to the base so that the staff can take it, and the positioning block 43 is adapted to the clutch intermediate shaft 5, that is, a key is provided on the side of the positioning block 43 close to the mounting shaft 41, and the key is adapted to the mounting hole opened on the clutch intermediate shaft 5. After the clutch intermediate shaft 5 is sleeved on the mounting shaft 41, the key is embedded in the mounting hole opened on the clutch intermediate shaft 5 to prevent it from rotating.

[0044] Among them, a positioning hole 411 is also provided on the mounting shaft 41, and the positioning hole 411 corresponds to the fixing protrusion 33. The positioning hole 411 is a through hole that passes through the mounting shaft 41, that is, the openings at both ends of the positioning hole 411 are parallel to the fixing protrusion 33 and are located on the same axis. On the one hand, it is convenient to locate the drilling position of the clutch intermediate shaft 5, and on the other hand, it prevents damage to the mounting shaft 41 during drilling, thereby extending the service life of the equipment.

[0045] In some preferred embodiments, in order to facilitate the rotation of the rotating shaft 31, a handle 311 is fixedly provided on one end of the rotating shaft 31 away from the mounting shaft 41. The handle 311 is L-shaped, which is convenient for staff to hold and operate.

[0046] In some preferred embodiments, the rotating shaft 31 and the mounting shaft 41 are integrally formed to improve the consistency of the rotating angles of the rotating shaft 31 and the mounting shaft 41 and to improve the drilling accuracy.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
