AI Technical Summary
During gear processing, the blade of the roller blade is difficult to directly contact the coolant, which increases the wear of the blade, thereby increasing production costs.
A roller insertion tool for gear processing is designed. By adding connection pipelines in the tool, the coolant is guided to the cutting position, and the combination of the drainage pipeline and the guide pipe is used to achieve accurate flushing of the cutting edge and reduce the wear of the blade.
It effectively reduces the wear of the blade, extends the service life, and through the design of the adapter bolt, the water pressure of the coolant is increased and the cooling effect is improved.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical processing and relates to a rolling cutter, in particular to a rolling cutter for gear processing. Background Art
[0002] Hobbing cutters are mainly used for gear hobbing and gear shaping. Through the rotation and feed motion of the hobbing cutter, the workpiece is cut to form the required tooth shape. This tool plays an important role in mechanical processing.
[0003] When the rolling cutter is processing gears, the contact point between the tool and the workpiece will be cooled through a guide tube. However, when processing gears, the contact point of the blade is inside the workpiece, and the external coolant is difficult to directly contact the cutting position, resulting in blade wear and increased production costs. Summary of the invention
[0004] The utility model aims to solve the above problems existing in the prior art and provides a gear machining hobbing cutter with low wear and high cooling efficiency.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a gear processing rolling cutter, characterized in that it includes a rolling cutter body, a plurality of cutting positions are evenly distributed spirally on the rolling cutter body, a blade mounting seat is provided on the cutting position, a blade clamping cavity is provided on the blade mounting seat, and a bolt mounting hole is provided on the blade mounting seat, a guide tube is protruded from the blade mounting seat, a connecting shaft hole is provided in the rolling cutter body, and a connecting hole connecting the connecting shaft hole and the guide tube is provided in the rolling cutter body.
[0006] In the above-mentioned gear machining rolling cutter, a blade is provided on the blade mounting seat, a drainage pipeline is provided on the blade, and the drainage pipeline is communicated with the connecting shaft hole.
[0007] In the above-mentioned gear machining rolling cutter, a transfer bolt is provided in the bolt mounting hole, and a hexagon socket hole is provided in the transfer bolt.
[0008] Compared with the prior art, the gear processing rolling cutter adds a connecting pipeline inside the tool to guide the coolant to the cutting position through the pipeline, and reduces the wear of the blade by accurately flushing the cutting edge. The adapter bolt can be replaced after the thread is stripped, thereby increasing the service life. The blade clamping cavity can better fix the blade and at the same time has better sealing performance to better prevent water from entering the blade, thereby increasing the water pressure of the coolant.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] like Figure 1 , 2 As shown in Figures 3, 4 and 5, the gear machining hob comprises a hob body 4, on which a plurality of cutting positions 7 are evenly distributed in a spiral manner, on which a blade mounting seat 3 is provided, on which a blade clamping cavity 1 is formed, and on which a bolt mounting hole 2 is formed, and on which a guide tube 5 protrudes, a connecting shaft hole 11 is formed in the hob body 4, and in which a connecting hole 10 connecting the connecting shaft hole 11 and the guide tube 5 is formed, and the blade clamping cavity 1 is in close contact with the blade 6, thereby increasing the airtightness, preventing the escape of water, and increasing the flushing pressure of the coolant.
[0017] Preferably, a blade 6 is provided on the blade mounting seat 3, and a drainage pipe 12 is provided on the blade 6. The drainage pipe 12 is connected to the connecting shaft hole 11. The coolant flows through the connecting shaft hole 11 in sequence through the connecting hole 10, the guide pipe 5, and the drainage pipe 12, and the water is delivered to the cutting processing area, so as to concentrate and accurately cool the blade 6 and reduce the wear of the blade 6.
[0018] Preferably, a transfer bolt 8 is provided in the bolt mounting hole 2, and a hexagonal hole 9 is provided in the transfer bolt 8. The transfer bolt 8 prevents the blade 6 from being unable to be installed due to the internal thread being stripped.
[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0020] Although the present invention uses more terms such as blade clamping cavity 1, bolt mounting hole 2, blade mounting seat 3, hob body 4, guide tube 5, blade 6, cutting position 7, adapter bolt 8, hexagon socket hole 9, connecting hole 10, connecting shaft hole 11, and drainage pipeline 12, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
