Description

Technical Field

[0001] This utility model relates to the field of transmission shaft processing technology, specifically to a support frame for processing automotive transmission shafts. Background Technology

[0002] The driveshaft is an important component in the automotive transmission system that transmits power. Its function, together with the gearbox and drive axle, is to transmit the engine's power to the wheels, thus generating driving force for the car.

[0003] Compare this to a positioning fixture for machining a transmission shaft, as described in application number CN202320569643.2. This positioning fixture includes a base, with support blocks on both the left and right sides of the top wall of the base. Each support block has a rotating ring on its inner wall, and threaded rods are evenly distributed on the inner wall of each rotating ring. Positioning frames are provided on the outer walls of each threaded rod. When fixing and supporting the transmission shaft, it is necessary to rotate the rotating adjusting rings at both ends sequentially to fix and support both ends of the transmission shaft. This process is cumbersome, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a support frame for processing automotive drive shafts, so as to solve the problem mentioned in the background art that requires two steps to complete the fixed support of the drive shaft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support frame for machining automotive drive shafts, comprising:

[0006] An adjustment component, wherein a limit component is installed at the middle position of the upper surface of the adjustment component;

[0007] A limiting assembly includes a support block, a rotating screw passing through the center of the support block, a rudder fixedly connected to the lower outer wall of the rotating screw, a second nut assembly connected to the outer wall of the rotating screw, a movable frame fixedly installed on the outer wall of the second nut assembly, guide rods fixedly connected to the lower ends of the movable frame, and two fixed rods symmetrically fixedly arranged on the upper inner side of the movable frame, with rotating rollers connected to the outer walls of the fixed rods.

[0008] Preferably, the adjustment assembly includes a base, with a bidirectional lead screw running through its interior. A cross handle is fixedly installed at one end of the bidirectional lead screw. A first nut pair is connected to the outer walls of both ends of the bidirectional lead screw. A guide block is fixedly installed on the outer wall of the first nut pair. A moving ring is fixedly connected above the guide block. A rotating ring is provided inside the moving ring. A large gear is fixedly installed on one side of the rotating ring. A small gear meshes with the lower outer wall of the large gear. A square rod runs through the interior of the small gear. A drive rod runs through the interior of the square rod. A servo motor is installed at one end of the drive rod.

[0009] Preferably, the support block is fixedly connected to the base, the rotating screw is rotatably connected to the support block, and the support block has a hole corresponding to the guide rod.

[0010] Preferably, the guide rod is slidably connected to the support block, and the rotating roller is rotatably connected to the fixed rod.

[0011] Preferably, the bidirectional lead screw is rotatably connected to the base, the guide block is slidably connected to the base, and the rotating ring is rotatably connected to the moving ring.

[0012] Preferably, the pinion is in close contact with the outer surface of the movable ring and is rotatably connected to the movable ring, while the pinion is slidably connected to the square rod.

[0013] Preferably, the square rod is fixedly connected to the drive rod, the drive rod is rotatably connected to the moving ring, and the output end of the servo motor is fixedly connected to the drive rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The new type of support block, through the setting of the limiting component, allows the drive shaft to pass through the inside of the rotating ring, with the middle part resting between the rotating rollers. Rotating the rudder causes the rotating screw to rotate, which in turn causes the second nut pair to move upward. The second nut pair causes the moving frame to move upward, which in turn causes the fixed rod and the rotating roller to move upward. The rotating roller lifts the drive shaft, so that the drive shaft located inside the rotating ring abuts against the inner side of the rotating ring, thus completing the fixed support of the drive shaft. There is no need to fix both ends of the drive shaft in sequence, which reduces the operation steps, saves time, and improves the efficiency of fixed support.

[0016] (2) By adjusting the configuration of the components, the transmission shafts of this new type of support block can be of different lengths. Before fixing the support, the cross handle can be rotated. The cross handle drives the double screw to rotate, and the double screw drives the first nut pair to move relative to each other. The first nut pair drives the guide block and the moving ring to move relative to each other, so that both ends of the transmission shaft can be located inside the rotating ring. This makes it convenient to fix and support transmission shafts of different lengths, thus improving the practicality and functionality of the support block. Attached Figure Description

Guide blocks 15 are fixedly installed on the outer walls of the nut pairs 14, serving a guiding function. A moving ring 16 is fixedly connected above the guide blocks 15. When the moving ring 16 moves, it can drive the pinion 19 to slide on the outer wall of the square rod 20. A rotating ring 17 is provided on the inner side of the moving ring 16. The rotation of ring 17 can drive the transmission shaft against the inner wall of the rotating ring 17 to rotate. A large gear 18 is fixedly installed on one side of the rotating ring 17. A small gear 19 meshes with the lower outer wall of the large gear 18. A square rod 20 passes through the inside of the small gear 19. A drive rod 21 passes through the inside of the square rod 20. The rotation of the drive rod 21 can drive the square rod 20 to rotate. A servo motor 22 is installed at one end of the drive rod 21. The servo motor 22 provides power. Starting the servo motor 22 can drive the drive rod 21 to rotate. The drive rod 21 drives the square rod 20 to rotate.

[0028] Furthermore, the support block 31 is fixedly connected to the base 11 to ensure the stability of the position of the support block 31. The rotating screw 32 is rotatably connected to the support block 31 to ensure that the support block 31 does not affect the rotation of the rotating screw 32. The rotation of the rotating screw 32 can drive the second nut pair 34 to move. The support block 31 has a hole corresponding to the guide rod 36, and the guide rod 36 plays a guiding role.

[0029] Furthermore, the guide rod 36 is slidably connected to the support block 31, and the guide rod 36 plays a guiding role. The rotating roller 38 is rotatably connected to the fixed rod 37. When the drive shaft is driven to rotate by the rotating ring 17, the rotating roller 38 rotates accordingly without affecting the rotation of the drive shaft.

[0030] Furthermore, the bidirectional lead screw 12 is rotatably connected to the base 11 to ensure that the base 11 does not affect the rotation of the bidirectional lead screw 12.

The rotating ring 17 is rotatably connected to the moving ring 16 to ensure that the moving ring 16 does not affect the rotation of the rotating ring 17. The rotation of the rotating ring 17 can drive the transmission shaft that abuts against the inner wall of the rotating ring 17 to rotate.

[0031] Furthermore, the pinion 19 is in close contact with the outer surface of the moving ring 16 and is rotatably connected to the moving ring 16, ensuring that the movement of the moving ring 16 can drive the pinion 19 to move without affecting the rotation of the pinion 19. The pinion 19 is slidably connected to the square rod 20, and the movement of the moving ring 16 can drive the pinion 19 to slide on the outer wall of the square rod 20.

[0032] Furthermore, the square rod 20 is fixedly connected to the drive rod 21, ensuring that the rotation of the drive rod 21 can drive the square rod 20 to rotate. The drive rod 21 is rotatably connected to the moving ring 16, ensuring that the moving ring 16 does not affect the rotation of the drive rod 21. The rotation of the drive rod 21 can drive the square rod 20 to rotate. The output end of the servo motor 22 is fixedly connected to the drive rod 21. The servo motor 22 provides power. Starting the servo motor 22 can drive the drive rod 21 to rotate, and the drive rod 21 drives the square rod 20 to rotate.

[0033] Working principle: In use, first rotate the cross handle 13 according to the length of the drive shaft. The cross handle 13 drives the double-acting lead screw 12 to rotate. The double-acting lead screw 12 drives the first nut pair 14 to move relative to each other. The first nut pair 14 drives the guide block 15 and the moving ring 16 to move relative to each other. The moving ring 16 drives the pinion 19 to slide on the outer wall of the square rod 20, so that both ends of the drive shaft can be located inside the rotating ring 17. Pass the drive shaft through the inside of the rotating ring 17, with the middle part resting between the rotating rollers 38. Rotate the rudder 33. The rudder 33 drives the rotating lead screw 32 to rotate, and the rotating lead screw 32 drives the second... Nut 34 moves upward, causing the moving frame 35 to move upward, which in turn causes the fixed rod 37 and the rotating roller 38 to move upward. The rotating roller 38 lifts the drive shaft, so that the drive shaft located inside the rotating ring 17 abuts against the inner side of the rotating ring 17. When the drive shaft needs to be flipped later, the servo motor 22 is started. The servo motor 22 drives the drive rod 21 to rotate, the drive rod 21 drives the square rod 20 to rotate, the square rod 20 drives the small gear 19 to rotate, the small gear 19 drives the large gear 18 and the rotating ring 17 to rotate, which in turn drives the drive shaft abutting against the inner side of the rotating ring 17 to rotate. The above is the complete working principle of this utility model.
