Description

Technical Field

[0001] The utility model relates to the technical field of gear processing equipment, in particular to a numerically controlled gear chamfering machine. Background Art

[0002] A gear chamfering machine is a machine tool that chamfers and rounds the ends of gear teeth. These machines typically operate semi-automatically, with a table capable of variable feed rates. They are essential processing equipment for the production of gear transmissions and other gear-shifting mechanisms. Gear chamfering machines utilize a dual-blade, separate mechanism. The cutters advance, and after a tooth is cut, the cutter shaft indexes the cutter and workpiece, allowing the next cut to begin. From the start of cutting, the workpiece completes the chamfering process with one complete revolution. However, existing gear chamfering machines generate metal debris that is difficult to clean and collect, consuming both labor and time.

[0003] See application number 202123267875.2, entitled "A Gear Chamfering Machine," which has ash collection holes on the side walls of the base, a groove on the top, and a strip-shaped ash hole on the bottom wall of the groove. The first motor is running and chamfering the gear while driving the cleaning brush to rotate, sweeping the debris in the groove and dropping it through the strip-shaped ash hole into the ash collection hole at the bottom, thereby collecting and cleaning the debris. Although this method can collect debris, the high-speed rotation during the gear chamfering process will cause the debris to splash, polluting the machine and the surrounding environment, and some of the debris does not splash into the groove, resulting in low debris collection efficiency.

[0004] This case was created to solve the above problems. Utility Model Content

[0019] The present invention will be further described in detail below through the accompanying drawings and examples.

[0020] like Figure 1-2The figure shows a CNC gear chamfering machine, comprising a base 1, a rotating base 2 mounted on the base 1, a chuck 3 mounted on the base 2, and a radially movable clamping jaw mounted on the top of the chuck 3. The clamping jaw has an L-shaped gripping end, which supports the gear 7 while supporting it from the inside to secure it. A hollow rotating drum 4 is pivotally connected to the rotating base 2, and a support rod 5 is movably connected to the rotating drum 4. The upper end of the support rod 5 is connected to a negative pressure suction seat 6, which is higher than the upper end of the gear 7 and extends toward the chamfering drill 9.

[0021] In order to absorb the debris splashed during rapid chamfering, this solution places the negative pressure suction seat 6 as close as possible to the working position of the chamfer drill 9 and the gear 7, so that the waste chips can be absorbed in the first time and the splashing problem can be reduced.

[0022] In view of the different shapes and sizes of gears 7, the horizontal position of the negative pressure suction seat 6 needs to be adjusted so that it is as close as possible without touching the chamfer drill 9. Figure 3-4 As shown, a sliding mechanism 8 is provided on the negative pressure suction seat 6 and the support rod 5. The sliding mechanism 8 includes a movable slot 84 provided on the lower side of the negative pressure suction seat 6. The upper end of the support rod 5 is connected to a limit block 85 and is slidably connected to the negative pressure suction seat 6. The limit block 85 is connected to a screw 81, and the upper end of the screw 81 passes through the upper part of the negative pressure suction seat 6. A through-groove 83 is provided on the negative pressure suction seat 6. The screw 81 is placed in the groove 83 and is screwed by a rotatable screw block 82 to fasten the negative pressure suction seat 6 to the support rod 5.

[0023] It should be noted that the negative pressure extends from below through the support rod 5 to the negative pressure suction seat 6 to achieve waste chip adsorption.

[0024] Secondly, since the height of the negative pressure suction seat 6 must always be higher than the top of the gears 7 of different sizes, and must be as close to the upper side of the gear 7 as possible, the present application improves the support rod 5 to achieve flexible changes in height.

[0025] See attached Figure 3 As shown, the lower end of the support rod 5 is connected to the bottom of the rotating drum 4 through a spring 11, and the height can be flexibly adjusted by pressing down. A locking groove 12 is opened on one side of the rotating drum 4. The corresponding side of the support rod 5 is connected to the locking rod outward and is placed in the locking groove 12. The locking rod can be fastened to the rotating drum 4 by the outer connecting block 13 (such as by screwing).

[0026] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
