Description

Technical Field

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

[0002] Gears are mechanical components with gears meshing continuously on a wheel rim to transmit motion and power. Gears have been used in transmissions for a long time. The principle of gear cutting, along with specialized machine tools and cutting tools utilizing this principle, emerged in the late 19th century. With the development of manufacturing, the smooth operation of gears has become increasingly important. After recasting, burrs may form on the sidewalls and edges of gears, necessitating secondary machining.

[0003] The Chinese patent with announcement number CN212552051U discloses a gear processing mold, including a base plate, a rotating shaft is rotatably mounted on the base plate, a fixing component for fixing the rotating shaft is provided on the base plate, a gear to be processed and a mounting component for fixing the gear to be processed are provided on the rotating shaft, a first vertical plate is fixed to the upper surface of the base plate, a crossbeam is fixed to the upper end of the first vertical plate, a second vertical plate is fixed to the end of the crossbeam away from the first vertical plate, a U-shaped sliding sleeve is fixed to the second vertical plate, a straight rack slidably connected to the U-shaped sliding sleeve is installed on the second vertical plate, a file slidably engaged with the tooth of the gear to be processed is provided at the lower end of the straight rack, and a driving component is installed on the crossbeam.

[0004] Although the gear processing mold described in the above patent can remove burrs on the tooth grooves of the cast gear by repeatedly moving the file up and down during use, on the one hand, the gear processing mold of the above structure is only provided with one file on one side of the gear to be processed, resulting in the gear to be processed only being able to file one tooth groove after one rotation, and the processing efficiency is relatively low. On the other hand, since the gear processing mold of the above structure can only fix one tool, when gears of different sizes need to be filed, the gear processing mold of the above structure needs to be replaced with different files. Since the files are mainly replaced by manually removing the bolts, the file replacement efficiency is relatively low, which is not convenient for efficient filing of gears of different sizes.

[0011] Furthermore, an operation panel is installed on one side wall of the bracket, and the operation panel is electrically connected to the motor 1, the motor 2, the bidirectional electric slide rail and the electric telescopic rod.

[0012] By adopting the above technical solution, the operation panel can control the coordinated work of motor 1, motor 2, the bidirectional electric slide rail and the electric telescopic rod by controlling the on and off of the circuit to ensure efficient filing of burrs on the tooth grooves on the gear.

[0013] Furthermore, the fixing portion of the electric telescopic rod is bolted to the sliding block on the bidirectional electric slide rail, and the telescopic portion of the electric telescopic rod is bolted to the connecting frame.

[0018] By adopting the above technical solution, it can be ensured that the cutter rod can pass through the cutter disc conveniently.

[0019] Furthermore, the limiting pin passes through the cutter rod and is fixedly inserted into the cutter disc.

[0020] By adopting the above technical solution, the limit pin can be easily pulled out and inserted from the cutter disc, so as to realize the convenient replacement of the cutter rod.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In order to solve the problem that the existing gear processing mold can remove burrs on the tooth grooves of the cast gear by repeatedly moving the file up and down when in use, on the one hand, the gear processing mold of the above structure is only provided with one file on one side of the gear to be processed, resulting in that the gear to be processed can only file one tooth groove after one rotation, and the processing efficiency is relatively low. On the other hand, since the gear processing mold of the above structure can only fix one tool, when it is necessary to file gears of different sizes, the gear processing mold of the above structure needs to replace different files accordingly.

[0031] like Figure 1-Figure 3 As shown, in this embodiment, the rotating fixing mechanism 3 includes a motor 301 installed in the middle of the bottom end of the support 2, a placement seat 302 installed at the power output end of the motor 301, and a locking bolt 303 installed in the middle of the upper end of the placement seat 302. The middle of the upper end of the placement seat 302 has a protrusion for positioning the center hole of the cast gear, and the locking bolt 303 is screwed to the protrusion on the placement seat 302.

[0032] like Figure 1-Figure 3As shown, in this embodiment, an operation panel 4 is further installed on one side wall of the bracket 1. The operation panel 4 is electrically connected to the motor 1 301, the motor 2 604, the bidirectional electric slide 501 and the electric telescopic rod 502. The operation panel 4 can control the coordinated operation of the motor 1 301, the motor 2 604, the bidirectional electric slide 501 and the electric telescopic rod 502 by controlling the on and off of the circuit to ensure efficient filing of burrs on the tooth grooves on the gear.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the fixed portion of the electric telescopic rod 502 is bolted to the sliding block on the bidirectional electric slide 501, the telescopic portion of the electric telescopic rod 502 is bolted to the connecting frame 601, and the bidirectional electric slide 501 drives the electric telescopic rod 502 to move closer to each other, which can ensure the synchronous movement of the two symmetrical cutter bars 603 on both sides of the gear to be processed, the motor 2 604 is bolted to the connecting frame 601, the power output shaft of the motor 2 604 is bolted to the cutter head 602, and the motor 2 604 is bolted to the cutter head 602. 04 drives the cutter disc 602 to rotate so that the tool rods 603 of different sizes can be aligned with the gears to be processed, so as to realize the automatic replacement of tool rods 603 of different sizes.

The bidirectional electric slide rail 501 and the electric telescopic rod 502 in the mechanism 5 can simultaneously make the two tool rods 603 contact the tooth grooves on the gear to be processed, ensuring that the two tooth grooves of the gear to be processed can be processed simultaneously during one rotation, so that the processing efficiency of the gear processing mold for the gear is improved. At the same time, with the design of the motor 2 604 and the cutter disc 602 in the tool changing mechanism 6, the mold can realize automatic replacement of tool rods 603 of different sizes when processing gears of different sizes, which is convenient for efficient filing processing of gears of different sizes.
