Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for an axial part. Background Art

[0002] In the processing of mechanical shaft parts, it is often necessary to machine radial holes on the shaft parts. When drilling, it is usually necessary to use a fixture and a drilling machine to perform the processing.

[0003] For example, the utility model patent with the announcement number CN203779166U discloses a drilling fixture for shaft parts, comprising: a drilling machine, an upper clamping plate, a lower clamping plate, and a workbench arranged in sequence from top to bottom. The upper and lower clamping plates are elastically connected by a connecting rod, a spring, and a locking nut, and each is provided with a pair of clamping bodies for positioning the shaft parts. The two pairs of clamping bodies are arranged opposite each other in an "eight" shape or an "outer eight" shape.

[0004] However, some axial parts usually need to drill radial holes at different circumferential angles when drilling. The existing drilling device needs to adjust the angle of the part by re-clamping after each drilling, which reduces work efficiency. At the same time, multiple clamping will also reduce the processing accuracy of the part. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-3The present invention provides a technical solution: a device for drilling holes in an axial part, comprising a base 1, wherein two mounting plates 2 are fixedly provided on the base 1, and a rotating drum 3 is rotatably provided in the two mounting plates 2. A plurality of clamping strips 12 that can move simultaneously are provided in the rotating drum 3, and the axial part can be clamped in the rotating drum 3 through the plurality of clamping strips 12. A worm gear 4 is fixedly provided on the outside of the rotating drum 3, and a worm gear 5 is rotatably provided on the base 1, and the worm gear 5 is meshed with the worm gear 4. A crank handle 6 is fixedly provided on one side of the worm gear 5, and the worm gear 5 can be rotated by rotating the crank handle 6. The rotation of the worm gear 5 can drive the rotating drum 3 to rotate, thereby adjusting the angle of the axial part in the rotating drum 3. A fixing plate 7 is fixedly provided on the base 1, and a slider 8 is slidably provided on the fixing plate 7. A motor 9 is fixedly installed on the slider 8, and a drill chuck 10 is fixedly provided on the driving end of the motor 9. The drill chuck 10 can be lowered by moving the slider 8 downward, and the drill bit installed on the drill chuck 10 is used to drill holes in the part.

[0019] As an embodiment of the present utility model, multiple pairs of guide cylinders 13 are fixedly provided in the rotating drum 3, and guide rods 14 that can be inserted into the guide cylinders 13 are fixedly provided on the clamping strip 12. The cooperation between the guide cylinders 13 and the guide rods 14 can limit the movement of the clamping strip 12 in the radial direction of the rotating drum 3.

[0020] As an embodiment of the present invention, a threaded barrel 15 is fixedly provided on the clamping strips 12, and a threaded rod 16 that can be screwed into the threaded barrel 15 is rotatably provided in the rotating drum 3. When the threaded rod 16 rotates, it can push the clamping strips 12 to move, thereby realizing the clamping of the parts. One end of the threaded rod 16 extends to the outside of the rotating drum 3 and is fixed with a gear 17, and a gear ring 18 is rotatably provided on the outside of the rotating drum 3. The rotation of the gear ring 18 can make the gear 17 drive the threaded rod 16 to rotate, and realize the simultaneous rotation of multiple threaded rods 16, so that multiple clamping strips 12 move simultaneously.
