DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1:

[0024] The utility model provides a protective device for high-speed drilling, milling and tapping machines. Figure 1-2 , including a tapping machine body 1, the tapping machine body 1 has a rotating shaft 2, and a protective mechanism is installed on the rotating shaft 2;

[0025] The protection mechanism can wrap the drill bit 21 on the rotating shaft 2, so as to prevent the drill bit 21 from being exposed to the outside and causing a worker to accidentally touch the drill bit 21, thereby making it safer to use and being able to be raised and lowered relative to the drill bit 21.

[0026] The protection mechanism includes a lifting assembly installed on the rotating shaft 2, and a protective cover 10 is detachably installed below the lifting assembly. The protective cover 10 is preferably made of a transparent material so that the working condition of the drill bit 21 can be observed from the outside; therefore, when the protective cover 10 contacts the workpiece and the drill bit 21 processes the workpiece, as the drill bit 21 descends, the lifting assembly can be retracted, thereby enabling the drill bit 21 to be lowered, thereby achieving protection when the drill bit 21 rotates.

[0027] The lifting assembly includes a ring 5 rotatably connected to the rotating shaft 2 through a bearing, a support rod 3 is welded on the outer wall of the ring 5, and a sleeve tube 7 is detachably installed on the bottom end of the support rod 3. Specifically, a first support connecting seat 4 is welded on the bottom end of the support rod 3, and the sleeve tube 7 is inserted into the inner wall of the first support connecting seat 4. Internal threaded holes are provided at corresponding positions of the sleeve tube 7 and the first support connecting seat 4, and the sleeve tube 7 and the first support connecting seat 4 are fixed by bolts. The inner wall of the sleeve tube 7 is slidably connected to the sleeve rod 8, and the sleeve tube 7 and the sleeve rod 8 are jointly sleeved with a first spring 6, and the bottom end of the sleeve rod 8 is detachably connected to the protective cover 10. Specifically, a second support connecting seat 9 is provided at the top end of the protective cover 10, and the sleeve rod 8 is inserted into the inner wall of the second support connecting seat 9. Internal threaded holes are provided at corresponding positions of the second support connecting seat 9 and the sleeve rod 8, and the second support connecting seat 9 and the sleeve rod 8 are fixed by bolts.

[0028] By connecting the ring 5 and the rotating shaft 2 through the bearing, when the protective cover 10 contacts the workpiece (or contacts the workpiece placement table), the first spring 6 drives the protective cover 10 to contact the workpiece tightly, so that the lifting assembly will not rotate with the rotating shaft 2, thereby ensuring the smooth operation of the rotating shaft 2; of course, even if the protective cover 10 is not in tight contact with the workpiece, the lifting assembly rotates slightly with the rotating shaft 2, and the obstruction to the operation of the rotating shaft 2 can be ignored, thereby ensuring the normal progress of the processing.

[0029] During specific use, the workpiece is placed on the operating table of the tapping machine body 1. When the rotating shaft drives the drill bit 21 to descend, the protective cover 10 also descends and contacts the workpiece. When the drill bit 21 rotates and descends to process the workpiece, the protective cover 10 always wraps the drill bit 21, thereby effectively avoiding the drill bit 21 from being exposed to the outside, thereby avoiding the situation where the worker accidentally touches the drill bit 21, and improving the safety of use; when the drill bit 21 rises, the first spring 6 recovers its deformation to reset the protective cover 10.

[0030] Embodiment 2:

[0031] Refer to the attached Figure 3-4 , which is different from Example 1, is that the lifting assembly includes a ring 5 rotatably connected to the rotating shaft 2 through a bearing, a support rod 3 is welded on the outer wall of the ring 5, and the support rod 3 is slidably connected to the guide rod 11. Specifically, a guide sleeve 12 is fixedly installed on the support rod 3, and the inner wall of the guide sleeve 12 is slidably connected to the guide rod 11. The guide rod 11 is sleeved with a second spring 13, and a third support connecting seat 15 is welded on the top of the protective cover 10. The guide rod 11 is inserted into the inner wall of the third support connecting seat 15, and the guide rod 11 and the third support connecting seat 15 are fixed by bolts; at this time, the structure of the lifting assembly is simpler.

[0032] During specific use, the workpiece is placed on the operating table of the tapping machine body 1. When the rotating shaft drives the drill bit 21 to descend, the protective cover 10 also descends and contacts the workpiece. When the drill bit 21 rotates and descends to process the workpiece, the protective cover 10 always wraps the drill bit 21, thereby effectively avoiding the drill bit 21 from being exposed to the outside, thereby avoiding the situation where the worker accidentally touches the drill bit 21, and improving the safety of use; when the drill bit 21 rises, the second spring 13 restores its deformation to reset the protective cover 10.

[0033] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
