Description

Technical Field

[0001] This utility model relates to the field of toothed workpiece processing technology, specifically to a toothed contour chamfering and deburring device. Background Technology

[0002] Common machining methods for toothed workpieces, such as gears, include: 1. Mechanical follow-up machining, such as the CNC small gear chamfering machine disclosed in patent CN104107957B. This machine has a contouring head below the chamfering tool. During movement, the contouring head's working surface remains in close contact with the tooth surface. The contouring head drives the chamfering tool to move synchronously along its trajectory. Its disadvantage is that it requires high precision in the contouring head's movement, and the gear's rotation speed cannot be too fast; otherwise, the chamfering tool is prone to skipping, affecting machining quality. 2. CNC machining. Its disadvantage is that each gear requires individual reprogramming, and existing CNC machine tools lack deburring functionality. Utility Model Content

[0003] The purpose of this invention is to provide a tooth profile chamfering and deburring device with high processing efficiency and good processing quality.

[0004] To achieve the above objectives, this utility model provides a tooth-shaped contour chamfering and deburring device, comprising a workpiece fixing assembly, a chamfering mechanism, and a control module. The workpiece fixing assembly includes a chuck and a workpiece rotation drive device, which drives the chuck to rotate along a preset rotation axis. The chamfering mechanism is located on one side of the workpiece fixing assembly and includes a chamfering cutter, a lifting assembly, a first translation assembly, and a first rotation assembly. The chamfering cutter is arranged facing the chuck. The first rotation assembly drives the chamfering cutter to rotate around its own axis. The lifting assembly and the first translation assembly drive the chamfering cutter to move up and down and horizontally, respectively, to work together to achieve the movement of the chamfering cutter along a preset feed trajectory. The control module is electrically connected to the workpiece rotation drive device, the lifting assembly, the first translation assembly, and the first rotation assembly, respectively, so that the chuck and the chamfering cutter are linked.

[0005] As can be seen from the above solution, by setting the chuck and chamfering tool to move in tandem, it is beneficial to improve machining efficiency and quality. Compared with existing follow-up machining, the chamfering tool of this invention actively moves along a preset feed trajectory under the control of the control module to achieve chamfering, which can effectively avoid tool skipping and help ensure the machining quality of toothed workpieces. This invention also has the advantages of simple structure and convenient operation.

[0006] A further solution is that the control module includes an input unit and a processing unit. The input unit is used to acquire the workpiece drawing, and the processing unit generates linkage machining code based on the workpiece drawing. The linkage machining code includes workpiece rotation code and chamfering machining code. The chuck rotates according to the workpiece rotation code, and the chamfering tool completes the chamfering machining according to the chamfering machining code.

[0007] As can be seen from the above solution, by setting an input unit to obtain workpiece drawings, such as the three views of a toothed workpiece, and the processing unit automatically generating linkage machining code based on the workpiece drawings, this utility model significantly reduces the burden on workers and greatly improves work efficiency compared with existing technologies that rely on manual CNC programming. During the machining process, the chuck drives the toothed workpiece to rotate according to the workpiece rotation code, and the chamfering tool moves according to the chamfering machining code. The two work together in a coordinated manner, which can significantly improve machining efficiency and ensure machining quality.

[0011] A further option is that the tooth profile chamfering and deburring device also includes a deburring mechanism, which is located on one side of the workpiece fixing assembly.

[0012] As can be seen from the above solution, the present invention integrates the deburring process, which can be performed immediately after the toothed workpiece is processed, eliminating the need to transfer the workpiece to a dedicated deburring equipment, thus ensuring the quality of the workpiece and significantly improving the overall processing efficiency.

[0013] A further embodiment is that the deburring mechanism includes a brush, a second translation component, a tilting component, and a second rotation component. The second translation component and the tilting component drive the brush to move horizontally and tilted, respectively, and the second rotation component drives the brush to rotate around its own axis.

[0014] A further embodiment includes a second base for the deburring mechanism; a second translation component is mounted on the second base, comprising a second translation seat, a second translation transmission component, and a second translation servo motor, wherein the second translation servo motor drives the second translation seat to move horizontally via the first translation transmission component; a tilting component is mounted on the second translation seat, comprising a tilting slide, a tilt transmission component, and a tilt servo motor, wherein the tilt servo motor drives the tilting slide to move tilted via the tilt transmission component; the brush and the second rotation component are both mounted on the tilting slide; the second translation servo motor, the tilt servo motor, and the second rotation component are all electrically connected to the control module.

The two ends of the second accordion cover are respectively connected between the second end of the horizontal guide rail and the second end of the second translation seat. The two ends of the third accordion cover are respectively connected between the first end of the inclined guide rail and the inclined slide.

[0016] As can be seen from the above scheme, by setting up the bellows cover, waste debris can be effectively isolated and prevented from falling into the movement path of the second translation seat and the inclined slide seat, thereby ensuring the smooth operation of the brush.

[0017] A further option is to use wire brushes, ceramic brushes, or nylon brushes. Attached Figure Description

A bearing 35 is sleeved on the outside of the connecting shaft portion 341 and is located between the support portion 342 and the pallet 33. The workpiece rotation drive device 32 drives the chuck 31 to rotate along a preset rotation axis via the rotating seat 34. This preset rotation axis is the center line of the clamping opening of the chuck 31. In this embodiment, the chuck 31 is a pneumatic chuck with its clamping port facing upwards; the dust cover 36 covers the lower part of the chuck 31 between the support plate 33 to prevent waste from falling between the chuck 31 and the rotating seat 34, as well as into the bearing 35, ensuring that the chuck 31 can rotate normally.

[0028] In this embodiment, the toothed workpiece 7 can be a gear or a turbine; this embodiment uses a gear as an example.

[0044] Brush 52 can be a wire brush, ceramic brush, or nylon brush. In actual work, the appropriate bristles can be selected according to actual needs.

[0045] This embodiment can be a dry processing method, in which case a dust collector (not shown in the figure) can be configured. The dust collector is located on the outside of the base 1, and the dust collection port of the dust collector extends into the protective cover 2 to suck up the dust.
