[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1, reference Figure 1-4 , a hydraulic locking structure for the sixth axis of a gear hobbing machine, comprising a mounting seat 1 and a U-shaped connecting seat 6, the outer wall of the mounting seat 1 being rotatably mounted on the U-shaped connecting seat 6 through a pin shaft 18, two pin shafts 18 being symmetrically fixed to the outer wall of the mounting seat 1, and the two pin shafts 18 being rotatably mounted on both sides of the U-shaped connecting seat 6 through bearings, an angle adjustment component for use with the pin shaft 18 and the U-shaped connecting seat 6 being mounted, an adjusting shaft 2 being slidably plugged into the front end of the mounting seat 1, the length of the adjusting shaft 2 being greater than the length of the mounting seat 1, a tool holder 3 being mounted on the adjusting shaft 2 through bolts, a milling cutter 4 being mounted on the tool holder 3, a mounting notch 5 being provided on one side of the tool holder 3, a locking component being mounted in the mounting notch 5;

[0025] The locking assembly includes a hydraulic push rod 12 fixed in the mounting groove 5, one end of the hydraulic push rod 12 is connected to a locking rod 8, one end of the locking rod 8 is slidably inserted in the mounting seat 1, a U-shaped support plate 11 is fixed in the mounting groove 5, the locking rod 8 passes through the vertical section of the U-shaped support plate 11, the locking rod 8 is located on the outer wall of the inner side of the U-shaped support plate 11, and a baffle 9 is fixedly sleeved, and the portion of the locking rod 8 located between the baffle 9 and the inner wall of the mounting groove 5 is sleeved with a spring piece 10;

[0026] The adjusting shaft 2 is T-shaped and is the sixth shaft of the gear hobbing machine. The adjusting shaft 2 is slidably inserted into the T-shaped slot provided on the mounting seat 1, and locking holes 15 are provided at equal distances on the adjusting shaft 2 to form a plug-in fit with the locking rod 8.

[0027] The angle adjustment assembly includes a worm wheel 13 fixedly sleeved on a pin shaft 18, a servo motor 14 and a bearing seat 17 are installed on one side of the inner side of the U-shaped connecting seat 6, a worm 16 is rotatably installed on the bearing seat 17 through a bearing, one end of the worm 16 is connected to the output end of the servo motor 14 through a coupling, and the worm 16 is meshed with the worm wheel 13;

[0028] The U-shaped connection seat 6 is provided with fixing holes 7. There are four fixing holes 7 which are respectively located at four corners of one side of the U-shaped connection seat 6. The fixing holes 7 of the U-shaped connection seat 6 are connected to the fifth shaft output end of the gear hobbing machine through bolts.

[0029] Working principle: the position of the milling cutter 4 is adjusted by moving the adjusting shaft 2 and the mounting seat 1 to make them slide relative to each other, and the locking rod 8 is pushed by the hydraulic push rod 12 so that the end of the locking rod 8 is inserted into the locking hole 15, so that the adjusting shaft 2 is fixed to the mounting seat 1 and will not slide relative to the mounting seat 1. At this time, the baffle 9 squeezes the spring piece 10 to prevent the connection part between the hydraulic push rod 12 and the locking rod 8 from falling off due to unexpected circumstances. The rebound effect of the spring piece 10 can be used to push the baffle 9 and the locking rod 8 back, so that the end of the locking rod 8 is disengaged from the locking hole 15, which is convenient for disassembling the adjusting shaft 2. The servo motor 14 drives the worm 16 to rotate, so that the worm 16 drives the worm wheel 13 and the pin 18 to rotate, and then drives the mounting seat 1 to rotate, so as to realize precise adjustment of the angle of the milling cutter 4. The operation is convenient and fast, and the practicability is good.
