Description

Technical Field

[0001] The invention relates to the technical field of gear shaping tools, and in particular to a gear shaping tool which is convenient for chip removal. Background Art

[0002] The principle of gear shaping is equivalent to the meshing of a pair of spur gears. The gear shaping cutter is equivalent to a displacement gear. Its cutting edge cuts the workpiece through up and down reciprocating motion to form the required tooth shape. When performing gear shaping on gears, a gear shaping machine is generally required for processing. The gear shaping machine drives the gear shaping cutter to move up and down and rotate to achieve gear processing. The gear shaping machine is mainly composed of a spindle, a tool holder, a gear shaping tool, a gear shaping machine base, a transmission mechanism and other parts. The existing gear shaping cutter is generally fixed to the tool holder by bolts.

[0003] The existing publication number is: CN101518841B. A gear shaping machine tool quick return device belongs to the technical field of gear shaping machines. The present invention uses a hydraulic servo system and a tool quick return mechanism to act on the gear shaping machine tool shaft, so that the gear shaping machine tool can be quickly returned. The quick return device includes a hydraulic servo system and a tool quick return mechanism, and the front connecting rod of the quick return device and the piston of the hydraulic servo system are connected to the tool shaft. The gear shaping machine tool quick return device provided by the present invention has a large cutting force and a cutting depth of 2-2.5 times that of the current gear shaping machine because it adopts a hydraulic servo system to control the movement of the tool shaft; at the same time, a four-link tool quick return mechanism is adopted to control the tool shaft, the cutting speed can be increased by 25%-50%, and variable circular feed cutting can be performed, and the circular feed amount can be increased by 50%; the overall efficiency of the machine tool can be increased by 3 times. The noise is greatly reduced during the working process, and hard gear surface processing can be performed.

[0004] However, when the existing gear shaping cutter is in use, since many gears are integrated with the mounting plate, the gear shaping cutter has a limited depth, and waste chips are easily accumulated between the gear shaping cutter and the mounting plate, which affects the falling of the gear shaping cutter, affects the processing effect of the gear, and affects the use effect of the gear shaping cutter.

[0039] Beneficial Effects

[0040] The present invention arranges a cooling centralized mechanism. When the gear is subjected to gear shaping processing, the gear shaping piston rod drives the gear shaping tool to move up and down. At this time, the driving extrusion member is squeezed by the tool holder body. At this time, the chip removal driving plate moves up and down under the action of the centralized driving spring. The centralized driving spring moves downward to drive the centralized driving member to move downward. The centralized driving member moves downward to squeeze the centralized protrusion, which facilitates the outflow of cutting fluid. At the same time, the centralized driving member opening will not limit the centralized protrusion. At this time, the centralized protrusion extends out under the action of the centralized connecting spring, which prolongs the retention time of the cutting fluid, avoids direct dripping of the cutting fluid, ensures sufficient contact between the cutting fluid and the gear, and ensures the cooling effect on the gear.

[0041] The present invention provides a chip discharge driving mechanism, the chip discharge trigger rod moves downward and drives the chip discharge limit rod to move downward, the chip discharge limit rod moves downward and drives the chip discharge connecting piece to rotate under the action of the chip discharge limit groove, the chip discharge connecting piece rotates and drives the chip collection piece to rotate, the chip collection piece rotates to collect the debris through the chip collection groove to the inner side of the chip collection piece, and at the same time, the chip collection piece rotates and drives the chip discharge groove to rotate. At this time, the chip discharge groove of the chip collection piece is staggered with the chip discharge groove of the chip discharge limiting plate. At this time, the waste chips are collected in the inside of the chip collection piece. When the chip discharge driving plate no longer squeezes the chip discharge limit rod, at this time, the chip discharge limit rod is driven upward under the action of the chip discharge connecting spring. At this time, the chip collection piece is reset, and the chip discharge groove of the chip collection piece is aligned with the chip discharge groove of the chip discharge limiting plate. The debris collected in the chip collection piece is washed off by the cutting fluid, which avoids the gear shaping tool squeezing the waste chips, avoids the accumulation of waste chips, facilitates the discharge of waste chips, ensures the accuracy of gear shaping processing, and improves the use effect of the gear shaping tool.
