Description

Technical Field

[0001] This utility model relates to the field of CNC gear turning machine technology, specifically to a high-efficiency offset CNC gear turning machine guide rail structure. Background Technology

[0002] In the field of CNC gear turning machines, the guide rail structure plays a crucial role in the machining accuracy, stability, and service life of the equipment. Currently, existing gear turning machine guide rail structures have the following shortcomings: The gear turning mechanism has a simple structure and poor adaptability to machining gears of different specifications. Vibration during machining is easily transmitted to the guide rail, interfering with the stability of the conveying and affecting the quality of the gear surface. The position monitoring methods for the gear turning mechanism and workpiece conveying components are not perfect, making it difficult to control the motion status in a timely and accurate manner. Overtravel and misalignment are prone to occur during machining, leading to equipment failure and scrap. The guide rail conveying components are mainly rigidly connected, and the vibration and impact forces during equipment operation are easily accumulated and transmitted, which not only affects the machining accuracy but also accelerates component fatigue and shortens the equipment maintenance cycle and service life. Finally, metal chips and dust generated during machining can easily enter the guide rail and transmission components, leading to accelerated wear and decreased accuracy.

[0003] Therefore, it is necessary to design an efficient offset CNC gear turning machine guide rail structure to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency offset CNC gear turning machine guide rail structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency biased CNC gear turning machine guide rail structure, the structure includes a frame, guide rail conveying assembly, gear turning mechanism, dustproof housing, transmission assembly and protective cover.

[0006] Furthermore, the rack serves as the overall support base for mounting various functional components.

[0007] Furthermore, the guide rail conveying assembly is mounted on the frame and includes a guide rail, a slider, a lead screw nut, and a lead screw nut seat. The guide rail is fixed on the guide rail frame, the slider slides and adapts to the guide rail, and the lead screw nut is adapted to be installed in the lead screw nut seat. The slider is driven to move along the guide rail through the lead screw drive to achieve precise conveying of the workpiece.

[0008] Furthermore, the gear machining mechanism is fixed on the slider via a machining connecting seat, and includes a machining motor and a honing wheel. The machining motor drives the honing wheel to rotate, performing high-precision machining on the tooth surface of the workpiece.

[0009] Furthermore, a dustproof housing covers the outside of the guide rail conveying assembly and the gear machining mechanism, while a protective cover is installed on the outside of the transmission assembly. Together, they form a double protection to prevent metal shavings and dust from entering.

[0010] Furthermore, the transmission assembly is connected to the axial side of the lead screw nut and consists of a drive motor, a first pulley, a second pulley, and a transmission belt. The drive motor drives the lead screw nut to rotate through the linkage between the pulley and the transmission belt, providing power to the guide rail conveying assembly.

[0011] Furthermore, the limit detection components are set on the left and right sides of the gear machining mechanism, including an infrared ranging sensor, a limit plate, and a hydraulic adjusting rod. The limit plate is connected to the guide rail conveying component by a hinge, and the two ends of the hydraulic adjusting rod are respectively hinged to the guide rail conveying component and the limit plate, which can adjust the angle of the limit plate. The transmitting end and receiving end of the infrared ranging sensor are respectively set on the limit plate and the gear machining mechanism to monitor the distance between them in real time to determine the position of the machining mechanism.

[0012] Furthermore, a disc spring is placed between the slider, the lead screw nut seat, and the machining connection seat. The top and bottom are fixedly connected to the machining connection seat, the slider, and the lead screw nut seat by bolts, forming an elastic buffer structure to absorb vibration and impact.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the design of a high-efficiency offset CNC gear turning machine guide rail structure, achieves the following effects: 1. In the limit detection component, the infrared ranging sensor, limit plate, and hydraulic adjusting rod work together to accurately monitor the position of the gear turning mechanism, provide timely feedback on the motion status, avoid overtravel and misalignment, ensure smooth processing flow, and reduce scrap rate and equipment failure probability; 2. The reasonable configuration of the gear turning mechanism adapts to different gear processing, and the drive structure of the processing motor and honing wheel ensures stable output of processing power. At the same time, the disc spring's shock absorption and buffering weakens the transmission of processing vibration to the guide rail, improving the quality of tooth surface processing and the stability of guide rail conveying. Furthermore, the disc spring is used in the processing of the connecting seat, slider, and lead screw... The elastic connection between the female seats effectively absorbs vibration and impact during processing, reduces the impact of rigid transmission on the stability of the guide rail conveying, and ensures the quality of gear surface machining; 3. In the guide rail conveying assembly, the matching structure of the lead screw nut and seat, and the slider and guide rail, combined with the machining connection seat, improves the transmission and sliding fit accuracy, reduces the impact of assembly clearance and stress deformation, reduces the workpiece conveying displacement error, and lays the foundation for high-precision gear machining; 4. Through the combination of dustproof shell and protective cover, the key structures such as the guide rail conveying assembly and transmission assembly are fully enclosed, effectively blocking the intrusion of metal chips and dust, reducing the risk of component wear, ensuring the long-term stable operation of the guide rail, transmission and other systems, and extending the equipment maintenance cycle.

When the drive motor 51 is working, it can drive the lead screw nut 23 to rotate through the transmission belt 54, thereby driving the slider 22 to move along the guide rail 21. Example

[0023] Please see Figure 4 Based on Embodiment 1, this embodiment further specifies that limit detection components 8 are provided on both the left and right sides of the gear machining mechanism 3 on the guide rail conveying assembly 2.

Example

[0024] Please see Figure 2 as well as Figure 4 Based on embodiment 1, this embodiment further specifies that multiple disc springs 9 are provided between the top of the slider 22 and the lead screw nut seat 24 and the bottom of the processing connection seat 7.

[0025] The working process of this utility model is as follows: When using this high-efficiency offset CNC gear turning machine guide rail structure, the frame 1 first provides stable support. After the equipment is started, the core components such as the drive motor 51 and the processing motor complete self-testing. The infrared ranging sensor 81 of the limit detection component 8 begins to monitor the initial position of the gear turning processing mechanism 3 in real time to ensure that each component is in a ready-to-work state. Then, the gear to be processed is placed in the designated position of the guide rail conveying component 2, and the workpiece is fixed by the matching fixture of the gear turning processing mechanism 3. At the same time, the hydraulic adjusting rod 83 adjusts the limit plate 82 to a preset angle to set the boundary for the processing stroke. The dustproof shell 4 and the protective cover 6 are in a closed state, forming double protection to prevent processing debris and dust from entering key parts such as the guide rail 21 and the transmission component 5. The disc spring 9 is in a pre-tightened state to prepare for vibration buffering during the processing. The drive motor 51 starts, driving the second pulley 53 to rotate via the first pulley 52 and the transmission belt 54. This, in turn, drives the lead screw nut 23 to rotate within the lead screw nut seat 24, causing the slider 22 to slide smoothly along the guide rail 21. This moves the machining connection seat 7 and the gear turning mechanism 3 toward the workpiece. When the gear turning mechanism 3 reaches the machining position, the machining motor drives the honing wheel to rotate at high speed to machine the gear teeth. During this process, the sliding cooperation between the slider 22 and the guide rail 21 ensures the movement accuracy, the PTFE wear-resistant layer reduces friction loss, and the infrared ranging sensor 81 continuously detects the distance between its transmitting end (located on the limit plate 82) and receiving end (located on the gear turning mechanism 3). The data is fed back to the control system in real time to ensure that the gear turning mechanism 3 operates within the set stroke and avoids overtravel. After processing is completed, the drive motor 51 reverses and drives the guide rail conveying component 2 to reset through the transmission component 5, and the gear processing mechanism 3 returns to the initial position; after the limit detection component 8 confirms that the reset is in place, the equipment enters the standby state and can process the next workpiece.
