Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, in an embodiment of the present utility model, a drill guide mounting structure 100 for a drilling machine includes: a guide assembly 10 and a connecting shaft 20. The connection shaft 20 is used to connect the drill and the drill bit 200. The guide assembly 10 is inserted to the connection shaft 20. A slide hole 21 is formed at the middle of the connection shaft 20. The guide assembly 10 includes: the positioning rod 11, the spring 12, the thimble 13, the gasket 14 and the magnet 15. One end of the positioning rod 11 is slidably inserted into the slide hole 21. A thimble 13 is mounted to the other end of the positioning rod 11. The gasket 14, the spring 12 and the magnet 15 are sequentially sleeved on the positioning rod 11. The spacer 14 abuts against the ejector pin 13.
Specifically, the arrangement of the guide assembly 10 effectively prevents the drilling machine from generating inclined holes in the drilling process, and improves the positioning accuracy.
As a specific embodiment, the ejector pin 13 is detachably mounted to the positioning rod 11.
As a specific embodiment, the positioning lever 11 is formed with a limit step. The limit step is used to prevent the magnet 15 from being separated from the positioning rod 11. The spring 12 and the limiting step are positioned on both sides of the positioning rod 11.
As a specific embodiment, the thimble 13 is mounted to the positioning rod 11 by screwing.
As a specific embodiment, one end of the connection shaft 20 is formed with a bit mounting structure. The bit mounting structure is used to mount the bit 200. The slide hole 21 is located at one end of the connection shaft 20 forming a bit mounting structure. The drill bit mounting structure is a thread structure.
As a specific embodiment, the end of the connecting shaft 20 remote from the bit mounting structure is formed with a drill connecting structure. The drilling machine connecting structure is a threaded structure.
As a specific embodiment, the drill mounting structure is an external thread structure. The drilling machine connecting structure is an internal thread structure.
In a specific embodiment, the magnet 15 has a circular ring-like structure.
As a specific embodiment, the center line of the slide hole 21 coincides with the rotation axis of the connection shaft 20 driven to rotate by the drill.
Working principle: first, the ejector pin 13 of the guide assembly 10 is abutted against the surface to be perforated, and then the drill is driven to drill the drill bit 200 to the surface to be perforated. In the process of drilling, the drill bit 200 applies acting force to the perforated surface, meanwhile, the ejector pin 13 and the perforated surface are propped against each other to overcome the acting force of the spring 12 to retract, the ejector pin 13 drives the positioning rod 11 to slide and retract towards the inside of the connecting shaft 20, and at the moment, the ejector pin 13 is completely positioned inside the drill bit 200. Finally, after the drilling is completed, the drill 200 is far away from the perforated surface, the ejector pin 13 is reset due to the acting force of the spring 12, and part of the ejector pin is exposed to the outer side of the drill 200.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
