The splines on the inner cylindrical surface are internal splines, and the splines on the outer cylindrical surface are external splines. Obviously, the spline connection is the development of the flat key connection in terms of number, and the spline is a standard structure.

[0003] In the prior art, patent announcement number CN218224492U is a double roller rolling device for spline processing. The above patent uses two rollers to quickly process the splines of the motor shaft, effectively replacing the previous hob processing, reducing the processing time from seconds to seconds, greatly shortening the time, improving processing efficiency, and increasing the strength and service life of the spline;

[0004] Although the above patent sets a waste collection groove on the bottom plate to collect the waste generated in the motor shaft processing process, in practice, the waste in the motor shaft rolling process is mostly splashed outward, and the waste collection groove is located below the roller, which can only collect some naturally fallen waste, but it is difficult to collect and process the splashed waste. The splashed waste splashes everywhere on the bottom plate, seriously affecting the use effect of the device. Utility Model Content

[0010] Preferably, the transmission component includes two tooth plates staggered vertically and a transmission rod laterally arranged between the two tooth plates, one end of the transmission rod is rotatably connected to the first support plate, and a transmission gear meshing with the tooth plates is fixedly sleeved on the rod body of the transmission rod.

[0011] Preferably, the other end of the transmission rod is fastened with a threaded sleeve, and a movable plate is threadedly connected to the wall of the threaded sleeve and is vertically fixed to the wall of the pushing cylinder.

The two protective seats can form a protective box with one end open outside the mounting seat, thereby effectively preventing the waste generated by the motor shaft processing from splashing around, limiting the movement range of the waste, and allowing the waste to fall into the collection box in a more concentrated manner.

[0027] The workpiece pushing mechanism includes a pushing cylinder 10 slidably arranged between the second support plate 9 and the first support plate 2. The side of the pushing cylinder 10 facing the first support plate 2 is open. Two electric telescopic rods 12 are symmetrically installed on the outer wall of the open end of the pushing cylinder 10. The telescopic rods of the electric telescopic rods 12 penetrate into the pushing cylinder 10 and are fixed with a clamping plate 11. A cylinder 13 is vertically installed on the side wall of the first support plate 2 away from the second support plate 9. The telescopic rod of the cylinder 13 penetrates the second support plate 9 and is fixed to the pushing cylinder 10.

[0028] When in use, after inserting one end of the motor shaft to be processed into the inner side of the push tube 10 in advance, the two electric telescopic rods 12 are immediately opened, and the telescopic rods of the electric telescopic rods 12 can drive the clamping plate 11 to slide inside the push tube 10 and contact the motor shaft, so that the two clamping plates 11 cooperate to clamp and fix the motor shaft;

[0029] Then, the cylinder 13 is turned on, and the telescopic rod of the cylinder 13 pushes the push cylinder 10 to slide toward the first support plate 2 until the motor shaft is located between the two rollers 7. Then, the drive motor 8 is turned on, and the output shaft of the drive motor 8 drives the bidirectional screw rod 4 to make the two nut seats 5, the motor 6 and the roller 7 slide towards each other. In this process, the motor 6 is started synchronously to make the roller 7 rotate. The rotating roller 7 contacts the motor shaft and can roll the motor shaft.

[0030] Further, refer to Figure 1 As shown, it is worth noting that a collection box located below the roller cutter 7 is provided on the top surface of the bottom plate 1;

[0031] By setting the collecting box, during the process of the rotating hob 7 processing the motor shaft, the collecting box can effectively collect the waste generated by the processing, so as to avoid manual centralized recycling at a later time.

[0032] Further, refer to Figure 1 , Figure 4 as well as Figure 5 As shown, it is worth noting that a space limiting mechanism is provided above the opening of the collecting box to prevent waste from splashing around;

[0033] The space limiting mechanism includes a protective cover arranged outside the mounting seat 3, the bottom end of the protective cover is open, and the protective cover is composed of two protective seats 14, the two protective seats 14 are symmetrically slidably arranged on both sides of the mounting seat 3, and a transmission component is arranged between the tops of the two protective seats 14, and a semicircular bayonet matching with the push cylinder 10 is opened on the side of the protective seat 14 facing the second support plate 9;

[0034] By setting the space limiting mechanism, in the process of opening the cylinder 13 and pushing the cylinder 10 to carry the workpiece to slide between the hobs 7, the two protective seats 14 in the space limiting mechanism can quickly move towards each other until they fit together under the action of the transmission parts, and the two protective seats 14 can form a protective box with an open end on the outside of the mounting seat 3, thereby effectively preventing the waste generated by the motor shaft processing from splashing everywhere, limiting the movement range of the waste, and allowing the waste to fall into the collection box more concentratedly.

[0035] Further, refer to Figure 1 As shown, it is worth noting that a glass plate 27 is fixedly embedded in the inner side wall of the protection seat 14 facing the mounting seat 3;

[0036] By providing the glass plate 27 , when the two protection seats 14 are closed outside the mounting seat 3 to form a protection box, a person can observe in detail through the glass plate 27 the processing of the motor shaft by the hob 7 .

[0037] Further, refer to Figure 1 As shown, it is worth noting that the transmission component includes two tooth plates 15 staggered in an upper and lower direction and a transmission rod 17 transversely arranged between the two tooth plates 15, one end of the transmission rod 17 is rotatably connected to the first support plate 2, and a transmission gear 18 meshing with the tooth plates 15 is fixedly sleeved on the rod body of the transmission rod 17;

[0039] Through the arrangement of the transmission components, in the process of the push cylinder 10 carrying the motor shaft sliding between the two roller cutters 7, the movable plate 20 can pass through the threaded sleeve 19 in advance, so that the two can control the rotation of the transmission rod 17 under the threaded structure, so that the transmission gear 18 is synchronously engaged with the two tooth plates 15, causing the two protective seats 14 to slide closer together.

[0040] Further, refer to Figure 1 and Figure 4As shown, it is worth noting that a U-shaped limiting rod 21 is fixed on the opposite sides of the two protective seats 14, and a limiting channel 22 is horizontally penetrated through the inner wall of the first support plate 2, and the ends of the two limiting rods 21 are respectively inserted from both sides of the limiting channel 22;

[0041] By setting the limit rod 21 and the slide, during the sliding process of the protective seat 14, the limit rod 21 can be displaced synchronously with the limit channel 22. In this way, the limit rod 21 and the slide can limit the moving trajectory of the protective seat 14 to ensure the stability of the protective seat 14 during movement.
