[0002] The spline shaft is a mechanical transmission component. Like flat keys, semicircular keys and oblique keys, it is used to transmit mechanical torque. A longitudinal keyway is provided on the outer surface of the spline shaft, and the rotating part mounted on the shaft also has a corresponding keyway to keep it rotating synchronously with the shaft.

[0003] During the machining process, the milling cutter cuts the surface of the spline shaft, but during the cutting process, only one group of spline shafts can be machined at a time, which will affect the efficiency of the spline shaft drawing. In addition, during the machining of the spline shaft, metal wire or dust will be generated during the cutting and drawing process. During the machining process, the equipment cannot clean and vacuum the spline shaft, which will cause dust to accumulate on the grooves opened on the spline shaft, affecting the construction quality of the spline shaft.

A dust removal mechanism is arranged directly above the processing mechanism. The dust removal mechanism sucks in metal dust of the spline shaft during the drawing process, and then cleans the metal wire on the surface of the spline shaft and the equipment.

[0006] Preferably, the dust removal mechanism includes a cutting support plate, a dust suction pipe, a dust collecting tank, a driving motor, an impeller and a columnar filter element. The dust collecting tank is arranged directly above the cutting support plate, the two sides of the dust collecting tank are connected through the dust suction pipe, the top of the dust collecting tank is connected through the output end of the driving motor, the output end of the driving motor is connected to the impeller, a columnar filter element is arranged on the outside of the impeller, and the cutting support plate is arranged directly above the base of the device.

[0023] In this embodiment, the dust removal mechanism 8 includes a cutting support plate 4, a dust suction pipe 5, a dust collecting tank body 6, a driving motor 7, an impeller 15 and a columnar filter element 16. The dust collecting tank body 6 is arranged directly above the cutting support plate 4, and the two sides of the dust collecting tank body 6 are penetrated by the dust suction pipe 5. The top of the dust collecting tank body 6 is penetrated by the output end of the driving motor 7, and the output end of the driving motor 7 is connected to the impeller 15. The outer side of the impeller 15 is provided with a columnar filter element 16, and the cutting support plate 4 is arranged directly above the device base 1.

[0024] In this embodiment, the dust collecting tank body 6 is connected to one end of the dust suction pipe 5 arranged on the left and right sides through an internally connected columnar filter element 16. The columnar filter element 16 blocks the dust base sucked into one side of the dust suction pipe 5 to prevent the impeller 15 from being damaged.

[0025] In this embodiment, the processing mechanism 9 includes a transverse guide rod 10, a fixture support plate 11, an external positioning groove 12, a CNC tool seat 13 and a milling blade 14. The transverse guide rod 10 is arranged between the two groups of side positioning seats 2. The transverse guide rod 10 symmetrically penetrates and is connected to the cutting support plate 4. The bottom end of the fixture support plate 11 is provided with an external positioning groove 12. The bottom end of the external positioning groove 12 is connected to the CNC tool seat 13. The two sides of the milling blade 14 are connected directly below the CNC tool seat 13. The corresponding diameter spline shaft is positioned by the fixture support plate 11 to complete the vertical broaching of the two groups of spline shafts.

[0028] This kind of spline shaft broaching equipment includes the following work contents in practical application:

[0029] Step 1: The operator first installs the milling cutter 14 under the CNC cutter holder 13, and positions the bottom end of the CNC cutter holder 13 with the outer side of the outer positioning groove 12, and positions the fixture through the fixture support plate 11 provided below, and positions and clamps the outer side of the spline shaft through the fixture, so that the milling cutter 14 contacts the surface of the spline shaft, and the spline shaft is longitudinally displaced by the milling cutter 14 to complete the slotting of the spline shaft;

[0030] Step 2: The operator selects a dust suction pipe 5 of a corresponding length according to the suction demand, and connects one side of the dust suction pipe 5 to the left and right sides of the dust collecting tank 6, and then adjusts and controls the suction part of the dust suction pipe 5, so as to facilitate the contact and correspondence between the spline shaft and the surface of the fixture support plate 11 in the processing process, and completes the suction processing of the processed debris;

[0031] Step 3: During the processing, the operator turns on the electric cylinder 3, and drives the cutting support plate 4 and the milling blade 14 arranged at the bottom to move longitudinally through the electric cylinder 3, so that the milling blade 14 cuts the surface of the spline shaft. The two groups of cutting milling blades 14 perform vertical processing on the spline shaft, and the cutting support plate 4 is laterally guided by the transverse guide rod 10, and the activity range of the cutting support plate 4 is controlled by the electric cylinder 3 to complete the processing of the spline shaft;

[0032] Step 4: During use, the operator turns on the drive motor 7 to drive the impeller 15 to rotate, uses the impeller 15 to accelerate the flow of air, and uses the dust suction pipes 5 set on both sides to inhale the dust generated by the processing, and isolates the heat-absorbing dust through the columnar filter element 16 to prevent metal dust from directly entering the outside of the impeller 15 and even causing damage to the outside of the impeller 15. The operator can open the opening at the bottom of the dust collecting tank 6 to complete the dust discharge.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
