Description

Technical Field

[0001] The utility model relates to the technical field of spline shaft processing, in particular to a spline shaft processing tool. Background Art

[0002] Spline shafts are a type of mechanical transmission. Like flat keys, woodruff keys, and bevel keys, they all transmit mechanical torque. Spline shafts have longitudinal keyways on their exterior, and rotating parts mounted on the shaft also have corresponding keyways, allowing them to rotate synchronously with the shaft. While rotating, some parts can also slide longitudinally on the shaft, such as transmission shift gears. During the milling process, spline shafts must be milled at designated locations on their exterior, necessitating a positioning tool.

[0003] For example, a spline shaft positioning processing tool with the publication (announcement) number CN215747767U includes a base, a longitudinal linear motor is symmetrically installed on one side of the top of the base, a fixing component is provided on the top of the longitudinal linear motor, the fixing component includes a support plate, vertical plates are symmetrically provided at both ends of the top of the support plate, and the middle positions of the adjacent sides of the two vertical plates are connected to a turntable through a rotating shaft, the bottom end of one of the vertical plates is movably connected to the support plate through a first transverse linear motor, and the other vertical plate is installed on the side away from the turntable with a servo motor, the output end of the servo motor passes through the vertical plate and is connected to the turntable, three fixing plates are installed on the adjacent sides of the two turntables, the three fixing plates are arranged in an equilateral triangle, and hydraulic rods are installed on the adjacent sides of the three fixing plates, the output end of the hydraulic rod is connected to a splint, and a milling assembly is provided on the side of the top of the base near the middle position of the support plate. The utility model is provided with a fixing assembly and a milling assembly, so that the device can perform positioning processing on spline shafts of different models and has strong adaptability.

Therefore, extra time is required to calibrate the cutting and milling components, which leads to extended downtime and further reduced production efficiency.

[0005] Therefore, a spline shaft processing tool is proposed to solve the above problems. Utility Model Content

[0012] Preferably, a curved T-shaped groove is provided at the bottom of the clamping block.

[0013] The beneficial effects of the utility model are:

[0014] 1.

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The horizontal rotation function is achieved through the cooperation of the first motor 2, the driving gear 4, the assembly plate 5, the arc rack 6, the arc T-shaped limit block 7, the driving mechanism 8, the clamping block 9, and the tightening mechanism 10. This can drive the spline shaft horizontally, so that it can be quickly moved to different workstations for processing, reducing the time for calibrating the cutting and milling components during the processing process.

[0027] The driving mechanism 8 includes a vertical plate 801 , a second motor 802 is fixedly mounted on one side of the vertical plate 801 , and a three-jaw chuck 803 is threadedly connected to an output end of the second motor 802 .

[0028] Reference Figure 1 and Figure 4 The function of clamping the spline shaft is achieved through the second motor 802 and the three-jaw chuck 803, thereby driving the spline shaft to rotate for subsequent surface processing.

[0029] The tightening mechanism 10 includes a third motor 1001, the output end of the third motor 1001 is set as a threaded rod 1002, a vertical plate 1003 is movably installed on the surface of the threaded rod 1002, a moving block 1004 is fixedly installed on the bottom of the vertical plate 1003, and a top pin 1005 is movably installed on the top of one side of the vertical plate 1003.

[0030] Reference Figure 1 and Figure 5 The function of moving the ejector pin 1005 is realized through the third motor 1001, the threaded rod 1002, the vertical plate 1003, and the moving block 1004, thereby being able to support spline shafts of different sizes, thereby ensuring the stability of the spline shaft during processing, and the ejector pin 1005 is used to facilitate supporting the end of the spline shaft.

[0033] A T-shaped limiting rod 13 is fixedly mounted in the middle portion of the top of the workbench 1 , and a through hole 14 is formed in the middle portion of the top of the assembly plate 5 .

After the other end of the spline shaft is supported by the ejector pin 1005, the rotating shaft 3 is driven to rotate by the first motor 2, and the driving gear 4 is driven to rotate by the rotating shaft 3. As the driving gear 4 rotates, a thrust is generated on the arc rack 6 to rotate, so that the assembly plate 5 rotates. During this period, the middle position of the assembly plate 5 is limited by the T-shaped limit rod 13 and the through hole 14. As the assembly plate 5 rotates horizontally, the spline shaft to be processed is moved to one side for processing. After a single processing, the driving gear 4 is driven to rotate again by the first motor 2 and the rotating shaft 3, and the arc rack 6 is reversely supported by the driving gear 4, so that the spline shaft is rotated to the other side for processing.
