Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a multi-station gear shaft synchronous machining equipment. Background Technology

[0002] Traditional gear shaft machining typically completes all processes on a single-station machine, requiring frequent loading, unloading, and handling of the workpiece. This not only wastes a significant amount of time and reduces production efficiency, but also easily causes damage to gear blanks and semi-finished products during loading, unloading, and handling, affecting gear quality. Furthermore, the precision of equipment at different stations varies, and each re-clamping of the workpiece introduces clamping errors, making it difficult to guarantee the machining accuracy of the gears. With the rapid development of the automotive and aerospace industries, the demand for gear shafts is constantly increasing, placing higher demands on their machining accuracy and production efficiency. The demand for gear shafts in new energy vehicle transmissions is surging in the automotive industry, requiring machining equipment with high speed, high precision, and high capacity. Traditional single-station machining equipment struggles to meet these demands. The development of multi-station forging technology and related technologies has provided technical support for the research and development of multi-station gear shaft synchronous machining equipment. Multi-station forging technology, as a highly efficient and energy-saving metal forming technology, has been widely used in the automotive, aerospace, and electronics fields. Multi-station forging equipment can achieve multiple forging processes in a single operation, improving production efficiency and machining accuracy, while significantly reducing the floor space required and facilitating integration with automation to form fully automated production lines.

[0003] The demand for gear shafts in new energy vehicle transmissions is surging in the automotive industry, requiring processing equipment with high speed, high precision, and high capacity. Traditional single-station processing equipment is difficult to meet these requirements. The development of multi-station forging technology and related technologies has provided technical support for the research and development of multi-station gear shaft synchronous processing equipment. In existing technologies, synchronous movement of multiple stations is achieved by designing specific mechanical structures. The gear rotates in conjunction with the spur teeth on the first slider, driving multiple gear blanks to move simultaneously toward and away from the central gear cutter, thus achieving synchronous cutting of multiple gear shafts. However, vibration of the workpiece during processing will cause high-frequency friction between the tool and the workpiece surface. Significant vibration marks appear on the processed surface, and in severe cases, surface tearing and chipping occur, affecting the wear resistance and transmission smoothness of the gear. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a multi-station gear shaft synchronous processing equipment, which aims to address the problem that vibration during workpiece processing can cause high-frequency friction between the tool and the workpiece surface, resulting in obvious vibration marks on the processed surface, and in severe cases, surface tearing and chipping, affecting the wear resistance and transmission smoothness of the gear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station gear shaft synchronous processing equipment, comprising a machine tool, a movable groove formed on the top surface of the machine tool, a transmission gear rotatably connected to the inner wall of the movable groove, a movable shaft slidably connected to the bottom of the inner wall of the movable groove, a fixed column fixedly connected to the top of the movable shaft, a fixed disk fixedly connected to the top of the fixed column, a sliding groove formed on the top of the fixed disk, a support pad slidably connected to the inner wall of the sliding groove, a threaded rod fixedly connected to the rear side of the support pad, a helical gear meshing with the outer wall of the threaded rod, a rotating disk fixedly connected to the top of the helical gear, a dustproof box fixedly connected to the outer wall of the threaded rod, and a processing cleaning mechanism provided on the rear side of the machine tool, the processing cleaning mechanism being used for workpiece processing and cleaning the processing table.

[0007] The processing and cleaning mechanism includes an air box, the front of which is fixedly connected to the rear of the machine tool. Multiple air pipes are fixedly connected to the top surface of the air box, and air jet valves are fixedly connected to the front of each air pipe. A power chamber is fixedly connected to the top surface of the air box, and a rotating ring is fixedly connected to the bottom front of the power chamber. A rotating shaft is slidably connected to the inner wall of the rotating ring, and a telescopic rod is fixedly connected to the bottom of the rotating shaft. A processing needle is fixedly connected to the bottom of the telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The machine tool has a waste trough on its top surface, and a splash guard is fixedly connected to the top surface of the waste trough.

[0010] As a further description of the above technical solution:

[0011] The machine tool has four fixed feet at the four corners of its bottom surface, and the bottom surface of each foot is fixedly fitted with an anti-slip pad.

[0012] As a further description of the above technical solution:

[0013] The machine tool has grooves fixedly connected to both its left and right sides, and a support rod fixedly connected to its rear side.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the gear to be processed is placed on a fixed disk, and the rotating disk drives the gear. The gear drives the threaded rod to extend and retract. After tightening, the transmission gear drives the fixed column to slide, and the fixed column drives the moving shaft to slide along the moving groove. Finally, the gear to be processed is driven to the designated position for processing. This achieves that the workpiece will not vibrate when clamped, and avoids the surface tearing and chipping caused by obvious vibration marks on the processed surface, which would affect the wear resistance and transmission stability of the gear.

[0022] 2. In this utility model, when the gear to be processed begins to be processed, the power chamber and air box are started, the rotating shaft rotates along the inner wall of the rotating ring, driving the telescopic rod to rotate, so that the processing needle can perform processing. The telescopic rod drives the rotating shaft to move up and down and rotate rapidly to achieve the processing purpose. The air box provides compressed air, which is transmitted to the jet valve through the air pipe to achieve processing and cleaning at the same time, avoiding transmission failures caused by processing waste and preventing efficiency reduction.

[0032] Specifically, the moving groove 13 and the transmission gear 12 ensure smooth transmission; the moving shaft 7 enables flexible movement; the moving shaft 7 and the fixed column 6 ensure structural stability; the fixed plate 5 enhances the overall structural robustness; the sliding groove 8 facilitates the movement and adjustment of the support pad 4; the outer wall of the threaded rod 9 meshes with the helical gear 11, ensuring transmission accuracy; the rotating plate 3 enables rotation; the dustproof box 10 protects the threaded rod 9 from dust and impurities; the processing and cleaning mechanism 2 processes the workpiece and thoroughly cleans the processing table after processing, ensuring a clean working environment; the splash guard 23 effectively prevents waste from splashing out, keeping the working area clean; and the anti-slip pad 15 prevents the machine tool 1 from sliding during operation, improving the safety and stability of the equipment.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The processing and cleaning mechanism 2 includes an air box 208. The front side of the air box 208 is fixedly connected to the rear side of the machine tool 1. Multiple air pipes 207 are fixedly connected to the top surface of the air box 208. An air jet valve 206 is fixedly connected to the front side of each air pipe 207. A power chamber 201 is fixedly connected to the top surface of the air box 208.

[0039] Working principle: The gear to be processed is placed on the fixed disk 5. The rotating disk 3 is rotated, which in turn drives the helical gear 11 to rotate, which in turn drives the threaded rod 9 to extend and retract. After tightening, the transmission gear 12 drives the fixed column 6 to slide, which in turn drives the moving shaft 7 to slide along the moving groove 13, which in turn drives the gear to be processed to the designated position for processing. This achieves the goal of preventing the workpiece from vibrating when clamped, avoiding the appearance of obvious vibration marks on the processed surface, which can lead to surface tearing and chipping, affecting the wear resistance and transmission smoothness of the gear.

[0040] When the gear to be processed is started, the power chamber 201 and the air box 208 are activated. The rotating shaft 203 rotates along the inner wall of the rotating ring 202, which in turn drives the telescopic rod 204 to rotate. Then the processing needle 205 performs processing. The telescopic rod 204 drives the rotating shaft 203 to move up and down and rotate rapidly, thereby achieving the processing purpose. The air box 208 provides compressed air, which is transmitted to the jet valve 206 through the air pipe 207, so as to achieve simultaneous processing and cleaning. This avoids transmission failures caused by waste during processing and avoids efficiency reduction due to failures.
