[0033] Reference Figure 1-6 The invention discloses an adjustable bowl-shaped gear shaping cutter installation device, which is used for the installation, fixation and adjustment of the bowl-shaped gear shaping cutter, in order to facilitate the fixed installation of the gear shaping cutter and to facilitate the adjustment of the gear shaping cutter.

[0034] The adjustable bowl-shaped gear shaping cutter installation device comprises a tapered shank seat 1, a cutter sleeve 3, a plurality of fixing screws 2 and a plurality of adjusting screws 6;

[0035] The tapered shank seat 1 is a Morse tapered shank. The bottom of the tapered shank seat 1 is disc-shaped, and the top is connected to the gear shaping machine. The tapered shank seat 1 is provided with four first countersunk holes 104 at equal intervals in a ring shape on the disc-shaped bottom. The tapered shank seat 1 can be fixed to the gear shaping machine through fixing bolts and the first countersunk holes 104. An internal stop 103 is provided in the middle of the disc-shaped bottom end of the tapered shank seat 1. The bottom of the tapered shank seat 1 is provided with four threaded fixing holes 101 at equal intervals in a ring shape. The bottom of the tool sleeve 3 is provided with four second countersunk holes 301 at equal intervals in a ring shape. Each fixing screw 2 is arranged in a second countersunk hole 301 and is threadedly connected to a fixing hole 101, so that the tool sleeve 3 can be fixedly connected to the tapered shank seat 1. Each first countersunk hole 104 and each fixing hole 101 are located on the same diameter circle of the tapered shank seat 1, and the fixing screw 2 is a standard 12.9 grade hexagon socket head screw.

[0036] A circular boss is provided at the bottom of the tool sleeve 3, a threaded mounting hole 302 is provided in the middle of the bottom end of the circular boss, a mounting screw 4 is provided in the mounting hole 302, an inner hole is provided in the middle of the gear shaping cutter 5, the mounting screw 4 is used to connect the tool sleeve 3 and the gear shaping cutter 5, a fixing ring 304 is provided at the bottom of the circular boss, the outer diameter of the fixing ring 304 is designed according to the inner hole size of the bowl-shaped gear shaping cutter 5, and the h3 tolerance is adopted. The fixing ring 304 is adapted to the inner hole of the gear shaping cutter 5, so that when the gear shaping cutter 5 is installed, the fixing ring 304 can be inserted into the inner hole, so that the gear shaping cutter 5 cooperates with the tool sleeve 3, and the tool sleeve is carried out. When the gear shaping cutter 5 is connected and fixed, the mounting screw 4 is passed through the inner hole of the gear shaping cutter 5 and the fixing ring 304, and then the mounting screw 4 is screwed into the mounting hole 302. The upper end of the mounting screw 4 is provided with a thread, and the thread specification uses metric fine pitch. The thread size M is designed according to the outer diameter D of the fixing ring 304, M = (2 / 3) D. The lower end of the mounting screw 4 is a large cone, and the top surface of the large cone can abut the gear shaping cutter 5, so that the gear shaping cutter 5 can be fixed to the bottom of the tool sleeve 3, and the bottom surface of the large cone is provided with a hexagonal inner hole, which is convenient for using an inner hexagon wrench to tighten the mounting screw 4.

[0037] A boss 303 is provided on the top of the tool sleeve 3. The boss 303 is a square boss with four planes spaced apart on its outer wall. The square boss is processed into a square with rounded corners. The boss 303 can be inserted into the inner stop 103. The tolerance of the inner stop 103 is H6, and the outer diameter tolerance of the boss 303 is h6. The disc-shaped outer wall of the tapered shank seat 1 is annular and has four adjustment holes 102 at equal intervals. Each adjusting screw 6 can be installed in an adjusting hole 102, and since each adjusting hole 102 is connected to the inner stop 103, one end of each adjusting screw 6 can be inserted into the inner stop 103, and one end of each adjusting screw 6 can be against a plane of the square boss. The gear cutter 5 can be adjusted by adjusting the four adjusting screws 6 in different directions. The adjusting screw 6 is a standard 12.9 grade hexagon socket head screw.

[0038] Working principle of the adjustable bowl-type gear shaping cutter mounting device:

[0039] During assembly, firstly, the taper shank seat 1 is installed on the gear shaping machine through the Morse taper shank and the first countersunk hole 104;

[0040] In addition, the tool sleeve 3 and the gear shaping cutter 5 are fixed, specifically, the mounting screw 4 is passed through the inner hole of the gear shaping cutter 5 and the fixing ring 304, and then the mounting screw 4 is screwed into the mounting hole 302. At this time, since the lower end of the mounting screw 4 is a large cone, the top surface of the large cone can abut the gear shaping cutter 5, and the gear shaping cutter 5 can be fixed to the bottom of the tool sleeve 3, so that the tool sleeve 3 and the gear shaping cutter 5 form a tool handle assembly;

[0041] Then insert the square boss on the upper part of the tool sleeve 3 into the inner stop 103 of the tapered shank seat 1, pass the fixing screw 2 through the second countersunk hole 301, and screw the fixing screw 2 into the fixing hole 101, so as to install the tool sleeve 3 on the tapered shank seat 1. During installation, it is necessary to pay attention to that the four planes of the square boss need to be aligned with the four adjustment holes 102 in the inner stop 103. At this time, the entire tooling has been installed on the gear shaping machine;

[0042] When the gear shaping cutter 5 needs to be adjusted, use a micrometer and rotate the entire tooling. According to the rotation of the micrometer needle, tighten the adjusting screws 6 at different positions on the tapered shank seat 1, so that one end of the adjusting screw 6 can be pressed against the square boss plane of the tool sleeve 3 and move slightly, thereby slightly adjusting the tool sleeve 3 until the micrometer needle changes less than 0.008mm. At this time, the tooling installation and adjustment are completed.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
