Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machining tools, and relates to a gear shaper cutter, in particular to a convenient disassembly taper shank gear shaper cutter. Background Technique
[0002] A gear shaper cutter is a gear-shaped or toothed bar gear machining tool, mainly used for machining internal and external meshing spur and helical cylindrical gears. The gear shaper cutter is mainly used for machining internal and external meshing spur and helical cylindrical gears by the generation method. In addition, it can also machine special gears such as gears with shoulders, multi-stage gears and herringbone gears without relief grooves, and special-shaped gear shaper cutters can machine various other profiled workpieces, such as cams and internal splines.
[0003] Conventional gear shaper cutters are fixed to the main shaft by multiple bolts, and the fixed installation is achieved through the self-locking property of the bolts. However, after changing the machining product, the cutter needs to be replaced to machine different gears. The conventional installation structure is complex to disassemble and assemble, and the installed cutter needs to be repeatedly adjusted, resulting in low production efficiency. Summary of the Invention
[0004] The purpose of the utility model is to provide a taper shank gear shaper cutter with convenient adjustment and disassembly for the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A convenient disassembly taper shank gear shaper cutter, characterized in that it includes a cutter body, an installation cavity is opened at the bottom of the cutter body, an external connection part is provided at the top of the cutter body, and a through hole is provided in the center of the cutter body. A threaded part is provided at the bottom of the external connection part and is placed in the through hole. A locking cover is also provided in the installation cavity. A plurality of locking bolts are annularly and evenly distributed on the locking cover, and the bottom of the locking bolt is fixed in the cutter body. A through hole for the locking bolt to pass through is opened on the locking cover.
[0006] In the above-mentioned convenient disassembly taper shank gear shaper cutter, a plurality of coaxially arranged installation rings are opened on the locking cover, and a plurality of trapezoidal springs are provided on the installation ring.
[0007] In the above-mentioned convenient disassembly taper shank gear shaper cutter, a guide groove is opened on the cutter body, and a guide strip is provided on the external connection part and is embedded in the guide groove.
[0008] In the above-mentioned convenient disassembly taper shank gear shaper cutter, a plurality of blade installation cavities are annularly and evenly distributed on the cutter body, and conversion blades are provided in each blade installation cavity.
[0009] Compared with the prior art, the present convenient disassembly taper shank gear shaper cutter is fixed to the external connection part by locking and stopping the cover on the cutter body, realizing quick disassembly and assembly. The locking force of the locking cover is increased by the locking bolt and the trapezoidal spring, and the trapezoidal spring can eject the locking cover during disassembly, reducing the difficulty of disassembly and assembly. Fixing by the locking bolt can prevent the cooling water from entering the installation cavity to prevent the internal components from rusting. Brief Description of the Drawings

Detailed Embodiment
[0014] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0015] As Figure 1 、 2 、shown in 3, the present convenient disassembly taper shank gear shaper cutter includes a cutter body 1, an installation cavity 8 is opened at the bottom of the cutter body 1, an external connection part 2 is provided at the top of the cutter body 1, and a through hole 14 is provided at the center of the cutter body 1. A threaded part 12 placed in the through hole 14 is provided at the bottom of the external connection part 2. A locking cover 6 is also provided in the installation cavity 8. A plurality of locking bolts 7 are annularly and evenly distributed on the locking cover 6, and the bottom of the locking bolt 7 is fixed in the cutter body 1. A through hole 10 for the locking bolt 7 to pass through is opened on the locking cover 6. During installation, first place the external connection part 2 on the cutter body 1, and rotate the locking cover 6 by engaging the installation tool with the through hole 10. The locking cover 6 is restricted from installation by the threaded part 12. After tightening, the locking bolt 7 locks the locking cover 6 to prevent the locking cover 6 from loosening.
[0016] Preferably, a plurality of concentric installation rings 9 are opened on the locking cover 6, and a plurality of trapezoidal springs 11 are provided on the installation rings 9. The trapezoidal springs 11 support the locking cover 6 between the cutter body 1 to further prevent the locking cover 6 from loosening.
[0017] Preferably, a guiding groove 13 is formed in the main body 1 of the inserting tool, and a guiding strip 3 embedded in the guiding groove 13 is arranged on the external connection part 2.
[0018] Preferably, a plurality of blade mounting cavities 5 are evenly distributed in a circular pattern on the main body 1 of the inserting tool, and a conversion blade 4 is arranged in each of the blade mounting cavities 5.
[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention.
