Description

Technical Field

[0001] The invention relates to the technical field of spline shaft processing equipment, in particular to an umbrella gear driven quantitative feeding spline shaft grinding machine. Background Art

[0002] A spline shaft grinder is a machine tool used to produce spline shafts. A spline shaft is a shaft used to connect two or more rotating components. This shaft is typically fixed to one component, while the other component has a matching spline groove. As the two components rotate, the spline shaft slides within the groove, transmitting torque. A spline shaft grinder can produce the spline portion of a spline shaft with high precision and surface quality.

[0003] Most of the existing spline shaft grinding machines used in the fine grinding process are ordinary workpiece grinders. The spline part of the spline shaft is ground by replacing the grinding tool. Although this type of grinder can process standard rectangular spline shafts and involute spline shafts, it is slightly insufficient for the fine processing of non-standard spline shafts, mainly reflected in: 1. The clamping tools are relatively simple, and most of them use ordinary three-jaw chucks for clamping and fixing. Although clamping is convenient, the calibration operation after clamping is more troublesome, and it takes a lot of time to calibrate the dividing head; 2. The grinding tool structure places the motor and the grinding tool together on the upper processing frame, so that the frame needs to rely on a heavier structure to maintain the stability of the processing, which also limits the movement mode of the grinding tool; 3. When processing the spline part, it is necessary to manually adjust the spline shaft angle multiple times to realize the processing of multiple spline grooves, etc., which is inconvenient to operate and the accuracy of the rotation angle is difficult to control.

The output end of the servo motor 31 is movably connected to the rotating sleeve 32, and the rotating shaft at one end of the gear 33 passes through the through hole of the outer shell 38 and is connected to a three-jaw chuck 34. An arc-shaped limit block 35 is provided in the outer shell 38, and a plurality of bosses 321 are evenly provided on the outer side of the rotating sleeve 32. A limit column 323 is slidingly provided in the boss 321, and a spring 322 is connected to the outer side of the limit column 323.

The outer end of the limit column 323 slides with the inner side of the arc-shaped limit block 35, and the inner end of the limit column 323 is intermittently meshed with the gear 33.

[0036] Combined with attachment Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the top of the outer shell 38 is provided with an adjustment platform 382, and a knob 37 is rotatably provided in the adjustment platform 382. The bottom of the knob 37 is connected to an adjustment gear 371. An adjustment arc block 36 is slidably provided in the internal cavity of the arc limit block 35.

[0037] The working principle of the quantitative transfer fixture 3: the servo motor 31 drives the rotating sleeve 32 to rotate, so that the limiting post 323 in the boss 321 rotates accordingly. During the rotation process, there is a gap between the bottom end of the limiting post 323 and the gear 33. At this time, the gear 33 and the three-jaw chuck 34 do not move. When the limiting post 323 rotates to the arc-shaped limiting block 35, the top of the limiting post 323 is squeezed by the arc-shaped limiting block 35, causing it to move inward, so that the bottom of the limiting post 323 cooperates with the gear 33, and the gear 33 rotates with the limiting post 323, driving the three-jaw chuck 34 to rotate. When the limiting post 323 leaves the arc-shaped limiting block 35, the spring 1 322 resets the limiting post 323. At this time, the gear 33 and the three-jaw chuck 34 stop rotating. Turning the knob 37 makes The adjusting gear 371 drives the adjusting arc block 36 to move, thereby achieving the extension effect of the arc limit block 35, thereby controlling the angle of each rotation of the three-jaw chuck 34, and lifting the pulling platform 351 so that the bottom of the arc limit block 35 coincides with the inside of the outer shell 38. At this time, the rotation of the servo motor 31 will not drive the gear 33 and the three-jaw chuck 34 to rotate. The conversion rod 39 is turned to make the conversion rod 39 push the rotating sleeve 32 to move, so that the ring gear 324 engages with the gear 33. At this time, the rotation of the servo motor 31 will drive the gear 33 and the three-jaw chuck 34 to rotate continuously, realizing three different working states of the three-jaw chuck 34. In actual application, the starting interval of the servo motor 31 can be controlled by programming, and three modes can be combined to achieve multiple working effects.
