Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft processing, in particular to a clamping mechanism for rotating shaft processing. Background Art

[0002] The rotating shaft is a shaft that must be used to connect the main parts of the product and is used to withstand both bending moments and torques during rotation. During the rotating shaft processing, a clamping mechanism is required to clamp and fix the rotating shaft and then process it.

When the clamping device for hardware rotating shaft processing is used, the electric push rod pushes the inclined plate upward to squeeze the rotating shaft upward between the inclined plate and the fixed frame, so that the inclined plate and the fixed frame cooperate to fix the rotating shafts of different diameters.

[0004] Although the existing clamping mechanism for shaft processing is convenient for fixing shafts of different diameters, it is found in use that when fixing the shaft, both ends of the shaft need to be fixed manually, resulting in low efficiency when disassembling and assembling the shaft, which in turn makes the overall processing efficiency of the shaft low and inconvenient to use. Therefore, we propose a clamping mechanism for shaft processing to solve the above problems. Utility Model Content

[0029] See also Figures 1 to 4 A clamping mechanism for shaft processing includes a base 1, a sliding seat 2 is symmetrically arranged on the top of the base 1, and a bracket 3 is fixedly connected to the top of the sliding seat 2, wherein,

[0030] The spacing between the brackets 3 is adjusted by an adjustment mechanism. The bracket 3 is rotatably connected to a rotating cover 8 on one side near the middle of the base 1. A clamping seat 9 is provided on the inner side of the rotating cover 8. A second slide groove 10 is symmetrically opened on the clamping seat 9 on one side near the middle of the base 1. A second slider 11 is provided in the second slide groove 10. The second slider 11 is fixedly connected to a clamping frame 12 near the outer side of the second slide groove 10;

[0031] The clamping frame 12 is fixedly connected to a clamping plate 13 on one side near the middle of the clamping seat 9, and a transmission rod 14 is symmetrically connected to the inside of the rotating cover 8. The transmission rod 14 is rotatably connected to the second slider 11 at one end away from the rotating cover 8. A spring 15 is installed between the clamping seat 9 and the rotating cover 8. A guide groove 16 is symmetrically opened on the inner wall of the rotating cover 8. A guide block 17 is fixedly connected to the side of the clamping seat 9 corresponding to the guide groove 16. The rotating cover 8 is driven by the driving mechanism to rotate;

[0032] When the rotating shaft needs to be clamped, the rotating shaft is placed between the brackets 3, and the brackets 3 are moved closer to each other through the adjustment mechanism, thereby driving the clamping seats 9 to move closer to each other. When the clamping seats 9 are against the ends of the rotating shaft, the rotating shaft pushes the clamping seats 9 to move toward the inside of the rotating cover 8. When the clamping seats 9 are moved through the transmission rod 14, the clamping plates 13 are driven closer to each other to clamp the rotating shaft. Through this clamping mechanism, the brackets 3 are moved toward both ends of the rotating shaft at the same time, so that the two ends of the rotating shaft can be clamped and fixed, which effectively improves the clamping efficiency of the rotating shaft and thus improves the processing efficiency of the rotating shaft.

[0033] See also Figures 1 to 4 The adjusting mechanism includes a first slide groove 4, a first slide groove 4 is opened on the top of the base 1 corresponding to the sliding seat 2, and a first slider 5 is fixedly connected to the bottom of the sliding seat 2 corresponding to the first slide groove 4, and a screw rod 6 is rotatably connected in the first slide groove 4. A first motor 7 is installed at one end of the base 1, and the shaft end of the first motor 7 is fixedly connected to the screw rod 6. Two opposite external threads are provided on the screw rod 6, and the screw rod 6 is threadedly connected to the first sliders 5 on both sides through the two opposite external threads. When the first motor 7 is working, it drives the screw rod 6 to rotate, and the screw rod 6 can drive the first sliders 5 on both sides to move in opposite directions through the two opposite external threads, thereby facilitating the control of the brackets 3 to move closer or farther away from each other.

[0034] See also Figures 1 to 4 The transmission rod 14 on the inside of the rotating cover 8 is in an eight-shaped shape. The clamping frame 12 is connected to the rotating cover 8 through the transmission rod 14. The guide block 17 is a rectangular column, and the width of the guide block 17 coincides with the width of the guide groove 16. When the clamping seat 9 and the rotating cover 8 move relative to each other, the clamping seat 9 drives the guide block 17 to move in the guide groove 16. The guide structure composed of the guide block 17 and the guide groove 16 can guide the movement of the clamping seat 9 and prevent the clamping seat 9 and the rotating cover 8 from rotating relative to each other.

[0035] See also Figures 1 to 4 The driving mechanism includes a second motor 18. The second motor 18 is installed on the outside of the bracket 3. The shaft end of the rotating cover 8 corresponding to the second motor 18 is fixedly connected to the first reversing gear 19. The shaft end of the second motor 18 corresponding to the first reversing gear 19 is fixedly connected to the second reversing gear 20. When the second motor 18 is working, it drives the second reversing gear 20 to rotate. The second reversing gear 20 drives the first reversing gear 19 to rotate through engagement, thereby driving one of the rotating covers 8 to rotate. The rotating covers 8 are transmitted through the clamped rotating shaft, so that the second motor 18 can drive the clamped rotating shaft and the rotating covers 8 at both ends to rotate at the same time, thereby controlling the rotation of the rotating shaft so as to process different positions of the rotating shaft.

[0036] Working principle: When using the clamping mechanism for shaft processing, Figures 1 to 4As shown, when the rotating shaft needs to be clamped, the rotating shaft is placed between the brackets 3, and the brackets 3 are moved closer to each other through the adjustment mechanism, thereby driving the clamping seats 9 to move closer to each other. When the clamping seat 9 is against the end of the rotating shaft, the rotating shaft pushes the clamping seat 9 to move toward the inside of the rotating cover 8. The transmission rod 14 is used to make the clamping seat 9 move and drive the clamping plates 13 to move closer to each other to clamp the rotating shaft. Through this clamping mechanism, the brackets 3 are moved toward both ends of the rotating shaft at the same time, so that the two ends of the rotating shaft can be clamped and fixed, which effectively improves the clamping efficiency of the rotating shaft and thus improves the processing efficiency of the rotating shaft. When the clamping seat 9 moves toward the inside of the rotating cover 8, the spring 15 is compressed. When the rotating shaft needs to be loosened, the brackets 3 are moved away from each other, and the clamping seat 9 is moved outward toward the rotating cover 8 through the spring 15. When the second motor 18 is working, it drives the second reversing gear 20 to rotate, and the second reversing gear 20 drives the first reversing gear 19 to rotate through engagement, thereby driving one of the rotating covers 8 to rotate. The rotating covers 8 are transmitted through the clamped rotating shaft, so that the second motor 18 can drive the clamped rotating shaft and the rotating covers 8 at both ends to rotate at the same time, thereby controlling the rotation of the rotating shaft so as to process different positions of the rotating shaft.
