Description

Technical Field

[0001] The invention belongs to the field of machine tool processing and relates to an automatically adjustable deburring device. Background Art

[0002] In the field of mechanical processing, gear hobbing is a commonly used gear processing method. However, after gear hobbing, the end face of the gear often forms flash or burrs, and the shape and size of these flash or burrs will present different states depending on the processing parameters. The presence of flash and burrs not only affects the appearance quality of the gear, but may also have an adverse effect on the transmission performance and service life of the gear.

[0003] The commonly used deburring methods on the market currently mainly include using disc cutters, turning tools and other tools for deburring operations. However, most of these methods use a fixed position, and the deburring effect will show differences. Even for the same batch of gears, the deburring effect will be inconsistent due to tool wear. In addition, when manually adjusting the tool position to compensate for wear, improper adjustment may cause cutting of the gear end face or unclean deburring, further affecting the quality and processing efficiency of the gear. Summary of the invention

[0037] The main shaft 11 is connected to the bearing seat 16 through the bearing 13, and drives the deburring knife 1 to rotate to perform the deburring operation.

[0038] The first receiving plate 12 is fixedly connected to the bearing seat 16 via a fourth hexagon socket head screw 18 , and is used to strengthen the connection between the main shaft 11 and the bearing seat 16 .

[0039] Bearing 13: supports the main shaft 11 to ensure that the main shaft 11 can rotate smoothly.

[0040] Inner spacer 14 and outer spacer 15 are arranged between bearings 13 to protect and support the bearings.

[0041] The bearing seat 16 is connected to the second mounting seat 19 through the fifth hexagonal cylindrical head screw 20 to support the main shaft 11 and the deburring knife 1 thereon.

[0042] The third hexagon socket head screw 17 is used to fix the main shaft 11 and the bearing 13 together.

[0043] The second mounting seat 19 is connected to the first guide rod 21 and the second guide rod 33 through the seventh hexagon socket head screw 31 to provide a stable mounting platform for the entire deburring device.

[0044] The first guide rod 21 and the second guide rod 33 jointly support the pull rod 35 to ensure the smooth movement of the deburring knife 1 during the adjustment process.

[0045] The second receiving plate 22 is fixedly connected to the first sleeve 28 through a sixth hexagon socket head screw 26 to strengthen the connection between the guide rod and the mounting seat.

[0046] The ball bearing 23 is arranged on the periphery of the first guide rod 21 to ensure the smooth rotation of the guide rod.

[0047] The end cover 24 and the limit block 25 are used to limit the travel of the first guide rod 21 to prevent excessive movement.

[0048] Sealing ring 27: arranged on the periphery of the second guide rod 33 to ensure the airtightness of the cylinder assembly.

[0049] First sleeve 28: supports and protects the guide rod and the bearing.

[0050] The first spacer sleeve 29 , the guide sleeve 30 and the locking ring 32 are used to fix and adjust the position of the pull rod 35 .

[0051] The second sleeve 34 is disposed on the periphery of the pull rod 35 to further support and protect the pull rod.

[0052] Pull rod 35: connects the oil cylinder assembly and the deburring knife 1, and realizes automatic adjustment of the deburring knife through the drive of the oil cylinder assembly.

[0053] The second spacer 36 is arranged on the top of the piston 39 to protect and support the piston.

[0054] The cylinder end cover 37 , the cylinder seat 38 and the piston 39 together constitute a cylinder assembly, and the extension and retraction of the pull rod 35 are achieved through the drive of the cylinder, thereby adjusting the position of the dehairing bayonet 1 .

[0058] The working principle of the present invention is:

[0059] Deburring process: The deburring blade 1 rotates under the drive of the spindle 11, contacts the gear end face and removes the flash and burrs. As the deburring blade 1 wears, the cylinder assembly drives the deburring blade 1 through the pull rod 35 to automatically adjust to compensate for the wear and ensure a stable deburring effect.

[0060] Air blowing system: High-pressure gas is ejected through the nozzle 2 to remove iron filings on the deburring knife 1, preventing the iron filings from sticking to the knife and causing poor deburring effect.

[0061] Position detection: The bump block 42 moves along with the movement of the deburring knife 1 . When the bump block 42 approaches the proximity switch 43 , a switch signal is triggered to precisely control the position of the deburring knife 1 .

[0062] Cylinder assembly drive: The cylinder assembly drives the pull rod 35 to extend and retract through the piston 39 in the cylinder seat 38, thereby driving the deburring knife 1 to automatically adjust. The airtightness of the cylinder assembly is guaranteed by the sealing ring 40 to ensure the stable transmission of the driving force.

[0063] Guiding and supporting: The first guide rod 21 and the second guide rod 33 jointly support the pull rod 35 to ensure the smooth movement of the deburring knife 1 during the adjustment process. The first sleeve 28 and the second sleeve 34 further support and protect the pull rod 35.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
