Description

Technical Field

[0001] This utility model relates to the field of gear shaft and gear processing technology, specifically a gear shaft and gear chamfering machine. Background Technology

[0002] A gear shaft chamfering machine is a mechanical device specifically used for chamfering gears on gear shafts. By chamfering the edges of the gears, it can remove sharp edges and burrs generated during the gear processing.

[0003] For example, a gear shaft chamfering machine with authorization announcement number "CN222344396U" uses a movable clamping plate to clamp gears of different inner diameters, increasing the applicability of the equipment. Simultaneously, the extrusion sleeve ensures the gear is more securely fastened to the turntable, preventing displacement during chamfering. The cylinder of this gear shaft chamfering machine activates, and its telescopic rod pushes the extrusion sleeve downwards, fitting it onto the clamping plate to secure the gear on the turntable. However, this method only processes one side of the gear shaft at a time; after completion, it must be re-clamped to process the other side. Each change requires positioning adjustment, clamping operations, and equipment waiting time. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, a gear shaft chamfering machine includes a base 1 and vertical blocks 3.

The output end of the electric telescopic rod 201 is fixedly connected to a first rectangular frame 202. Both sides of the inner wall of the first rectangular frame 202 are rotatably connected to the first gear 204 through bearings. The first gear 204 rotates inside the first rectangular frame 202 through bearings. The left end of the first rectangular frame 202 is threadedly connected to the first servo motor 203 through bolts. The first servo motor 203 is installed on the first rectangular frame 202 through bolts. The output shaft of the first servo motor 203 is fixedly connected to the first gear 204.

[0024] Both ends of the first rectangular frame 202 are fixedly connected to protrusions 205. The outer wall of the protrusion 205 is fixedly connected to the vertical block 3, and the inner wall of the protrusion 205 is slidably connected to the first slide rod 206.

[0027] Working principle

[0028] When using a gear shaft and gear chamfering machine:

[0029] Fixing the gear shaft:

[0030] Place the gear shaft 12 on the two rollers 10 on both sides, connect the external power supply to the second servo motor 601, start the second servo motor 601, and the output shaft of the second servo motor 601 will rotate, driving the rod 602 to rotate (e.g., Figure 2The rotation of the round rod 602 drives the two first bevel gears 603 to rotate, and the rotation of the first bevel gears 603 drives the two second bevel gears 604 to rotate. The two second bevel gears 604 rotate in opposite directions, and the rotation of the second bevel gears 604 drives the two threaded rods 605 to rotate. The threaded rods 605 rotate in opposite directions, and the rotation of the threaded rods 605 drives the threaded block 606 to move. The movement of the threaded block 606 drives the fixed block 7 to slide on the second slide rod 13. The second slide rod 13 limits the threaded block 606 to prevent the threaded block 606 from rotating with the rotation of the threaded rod 605. The movement of the fixed block 7 drives the vertical rod 8 to move, and the movement of the vertical rod 8 drives the second rectangular frame 9 to move. The movement of the second rectangular frame 9 drives the round roller 10 to move downward until both ends of the gear shaft 12 are in contact with the round roller 10. Then the second servo motor 601 is turned off, thus completing the fixation of the gear shaft 12, so that the operator can clamp and process both ends of the gear shaft 12 at the same time.

[0031] Chamfering operation on gear shafts and gears:

[0032] When chamfering the gear shaft, the chamfering tool must be rotated to ensure that each part of the gear contacts the chamfering tool in sequence. Therefore, the electric telescopic rod 201 is activated, and the output end of the electric telescopic rod 201 moves, causing the first rectangular frame 202 to move (e.g., ...). Figure 2 The first rectangular frame 202 moves, causing the protrusion 205 to slide on the first slide rod 206. The first slide rod 206 limits the protrusion 205 and makes it move only in a straight line. The movement of the first rectangular frame 202 causes the first gear 204 to move towards the second gear 11 until the teeth of the first gear 204 mesh with the second gear 11. Then the electric telescopic rod 201 is closed. The electric telescopic rod 201 can be an electric telescopic rod with a self-locking function. The first servo motor 203 is turned on. The speed of the first servo motor 203 can be adjusted according to the specific working conditions of the operator. The output shaft of the first servo motor 203 rotates, causing the first gear 204 to rotate. The rotation of the first gear 204 drives the second gear 11 to rotate. The rotation of the second gear 11 drives the gear shaft 12 to rotate. The gear shaft and gear are then chamfered by an external angle grinder or a handheld chamfering machine.

[0033] After the gear shaft is chamfered, the chamfering tool is turned off and placed to one side. The first gear 204 is reset by the electric telescopic rod 201, and the upper roller 9 is reset by the second servo motor 601. All power is turned off, and the gear shaft is taken out, thus completing the working process of the gear shaft chamfering machine.
