As modern industry develops towards high precision, high efficiency, and high flexibility, extremely stringent requirements are placed on the performance of tooling for machining shaft parts.

[0003] When existing technical solutions are used,

Detailed Implementation

[0027] Please see Figure 1-7 This utility model provides a technical solution: a combined shaft part processing fixture, including an operating platform 1, a shaft part fixing mechanism 2, a processing mechanism 3, a cleaning mechanism 4, and a stabilizing mechanism 5. The top of the operating platform 1 is provided with a placement slot 11. The shaft part fixing mechanism 2 is fixedly connected to the inside of the placement slot 11. The processing mechanism 3 is threadedly connected to the top of the operating platform 1 and fixedly connected to the inside of the placement slot 11. The cleaning mechanism 4 is fixedly connected to the edge of the top of the operating platform 1. The stabilizing mechanism 5 is fixedly connected to the bottom of the operating platform 1.

[0028] The following section will describe in detail the specific setup and function of its shaft-type parts fixing mechanism 2, machining mechanism 3, cleaning mechanism 4, and stabilizing mechanism 5.

[0029] In this embodiment: the shaft part fixing mechanism 2 includes a connecting component 21 that is fixedly threaded to the top edge of the operating platform 1 and symmetrically arranged. A rotator 22 is fixedly connected inside the connecting component 21. A threaded rod 23 is fixedly connected to the output end of the rotator 22. The far end of the threaded rod 23 is rotatably connected to the inside of the symmetrically arranged connecting component 21. A shaft part connecting shaft 24 is threadedly connected to the outer surface of the threaded rod 23. The shaft part connecting shaft 24 is hollow and its diameter gradually decreases.

[0030] The effect achieved by the above components is as follows: when the length of shaft parts is different, the position of the fixing plate 213 can be adjusted to adapt to different sizes. The rotator 22 drives the threaded rod 23 to rotate, and the shaft connecting shaft 24 of the shaft parts moves on the threaded rod 23. Because it is hollow and the diameter gradually decreases, it can adaptively clamp shaft parts of different diameters, realize the rapid positioning and firm fixation of shaft parts, and improve the versatility of tooling.

[0031] Specifically, the connecting component 21 includes a fixed frame 211 threadedly connected to one side of the top of the operating platform 1, with connecting pieces 212 threadedly connected to both sides of the fixed frame 211. The fixed frame 211 is threadedly connected to the top of the operating platform 1 through the connecting pieces 212. The connecting component 21 also includes a fixed plate 213 threadedly connected to the other side of the top of the operating platform 1. A sliding plate 214 is fixedly connected to the bottom of the fixed plate 213, with connecting pieces 212 threadedly connected to both sides of the fixed plate 213. The fixed plate 213 is slidably connected to the top of the operating platform 1 through the sliding plate 214, and the fixed plate 213 is threadedly connected to the top of the operating platform 1 through the connecting pieces 212.

[0032] The effect achieved by the above components is as follows: after sliding the fixed plate 213 to the appropriate position, tightening the connecting piece 212 can lock the fixed plate 213, providing a stable support foundation for shaft parts and ensuring the reliability of subsequent fixing and processing operations.

[0033] Specifically, the processing mechanism 3 includes a servo motor 31 fixedly connected inside the placement slot 11. The output end of the servo motor 31 is fixedly connected to a main rotating shaft 32. A rotating belt 33 is rotatably connected to the outer surface of the main rotating shaft 32. A secondary rotating shaft 34 is rotatably connected inside the rotating belt 33.

[0034] The effect achieved by the above components is as follows: the servo motor 31, as the core power source, can accurately control the speed and torque, and its output power is transmitted to the main rotating shaft 32. The main rotating shaft 32 transmits the power to the slave rotating shaft 34 in a non-rigid connection through the rotating belt 33.

[0035] Specifically, a threaded rotating rod 35 is fixedly connected to the outer surface of the main rotating shaft 32 and the outer surface of the driven rotating shaft 34. A bearing 36 is rotatably connected to the outer surface of the threaded rotating rod 35. The outer surface of the bearing 36 is fixedly connected to the inside of the operating platform 1. A connecting rod 37 is fixedly connected to the outer surface of the driven rotating shaft 34. The connecting rod 37 is rotatably connected to the inside of the operating platform 1.

[0036] The effect achieved by the above components is as follows: the main rotating shaft 32 and the driven rotating shaft 34 drive the threaded rotating rod 35 to rotate. The bearing 36 is installed inside the operating platform 1 to provide support and radial constraint for the threaded rotating rod 35, reduce frictional resistance and radial runout during rotation, and ensure that the threaded rotating rod 35 rotates smoothly and accurately.

[0037] Specifically, a sliding block 38 is rotatably connected to the outer surface of the threaded rotating rod 35, a rotating motor 39 is fixedly connected inside the sliding block 38, a connecting plate 310 is fixedly connected to the output end of the rotating motor 39, adjusting bolts 311 are threadedly connected to both sides of the connecting plate 310, and a shaft-type part processing tool 312 is threadedly connected to the outer surface of the connecting plate 310. The shaft-type part processing tool 312 is threadedly connected to the outer surface of the connecting plate 310 through the adjusting bolts 311.

[0038] The effect achieved by the above components is as follows: when the threaded rotating rod 35 rotates, the thread on its outer surface engages with the threaded hole in the sliding block 38, converting the rotational motion into the linear motion of the sliding block 38, causing the sliding block 38 to move axially along the threaded rotating rod 35, thereby driving the rotating motor 39, the connecting plate 310 and the processing tool to the designated processing position.

[0039] Specifically, the cleaning mechanism 4 includes support columns 41 fixedly connected to the four corners of the top of the operating platform 1. A support frame 42 is fixedly connected to the top of the support column 41. A blower 43 is fixedly connected inside the support frame 42. A dustproof frame 44 is threadedly connected to the bottom of the support frame 42. Limiting members 45 are threadedly connected to both sides of the dustproof frame 44. The dustproof frame 44 is threadedly connected to the bottom of the support frame 42 through the limiting members 45.

[0040] The effect achieved by the above components is as follows: When the blower 43 is working, it blows out a strong airflow, which can effectively blow away metal shavings, chips and other impurities generated during the processing, prevent the chips from accumulating in the processing area, avoid the chips from scratching the workpiece surface or affecting the normal cutting of the tool, and ensure processing accuracy.

[0041] Specifically, the stabilizing mechanism 5 includes dampers 51 threaded to the four corners of the bottom of the operating platform 1, shock-absorbing telescopic springs 52 sleeved on the outer surface of the dampers 51, and anti-slip bases 53 fixedly connected to the bottom of the dampers 51 and the shock-absorbing telescopic springs 52.

[0042] The effect achieved by the above components is as follows: the shock-absorbing telescopic spring 52 has elastic deformation characteristics. When the tooling vibrates during processing, the spring absorbs the vibration energy by compression or stretching, playing a buffering role and preventing the tooling from displacing due to vibration or cutting force during processing, thus providing a stable support foundation for the entire tooling.

[0043] Working principle: When using this combined shaft part machining fixture, firstly, according to the length of the shaft part, it is fixed by sliding fixing plate 213 and connecting piece 212, and the spacing of connecting assembly 21 is adjusted. Then, the shaft part is placed in shaft part connecting shaft 24. The rotator 22 is started, which drives the threaded rod 23 to rotate, so that shaft part connecting shaft 24 moves to clamp the shaft part. Next, servo motor 31 is started, which drives threaded rotating rod 35 to rotate through main rotating shaft 32, rotating belt 33 and driven rotating shaft 34. Sliding block 38 moves on threaded rotating rod 35 to move shaft part machining tool 312 to a suitable machining position. At the same time, according to the machining requirements, the position of machining tool is adjusted by adjusting bolt 311, and rotating motor 39 drives machining tool to process shaft part.

[0044] During the processing, the blower 43 works continuously to blow away the generated debris and prevent the debris from interfering with the processing. The damper 51 and the shock-absorbing telescopic spring 52 effectively absorb the vibration generated during the processing. The anti-slip base 53 ensures the stability of the tooling and ensures the processing accuracy. After the processing is completed, the power to each component is turned off.
