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 6, in an embodiment of the present utility model, a drill bit guiding structure of a drilling machine includes: a drill output shaft and a drill guide assembly 100. Specifically, the arrangement of the drill guide assembly 100 effectively prevents the drill from producing a slant hole during drilling, and improves the accuracy of positioning.
The drilling machine output shaft is provided with a first mounting structure and a second mounting structure. The first mounting structure is for mounting a drill bit. The second mounting structure is for mounting the drill guide assembly 100. The drill guide assembly 100 includes: a gas spring 10, a tip 20, a connecting inner shaft 30 and a connecting outer shaft 40. The outer shaft 40 is connected for connection with a drill. The connecting outer shaft 40 is mounted to the second mounting structure. The inner connecting shaft 30 is rotatably mounted to the outer connecting shaft 40. The inner connecting shaft 30 is fixed to the tail of the gas spring 10. The tip 20 is mounted to the head of the gas spring 10. Specifically, the center is mounted on the head of the gas spring, and when the center is subjected to external force, the acting force of the gas spring can be overcome to enable the gas spring to stretch and retract.
As a specific embodiment, the first mounting structure and the second mounting structure are both screw structures.
As a specific embodiment, one end of the connecting inner shaft 30 is fixed to the tail of the gas spring 10. The other end of the connection inner shaft 30 is formed with a stem 31. The stem 31 is rotatably inserted into the connecting outer shaft 40.
As a specific embodiment, an O-ring seal is provided between the inner connecting shaft 30 and the outer connecting shaft 40.
As a specific embodiment, the stem 31 is provided with a mounting groove for mounting an O-ring. An O-ring seal is provided between the stem 31 and the connecting outer shaft 40.
As a specific embodiment, the inner connecting shaft 30 is screwed to the tail of the gas spring 10. The stem 31 is provided with a flat structure for facilitating the user to rotate and install the connecting inner shaft 30.
As a specific embodiment, the connecting outer shaft 40 is provided with a screw structure for connecting to a drilling machine. The outer surface of the connecting outer shaft 40 is provided with a flat structure. The flat configuration facilitates the user in rotating the outer shaft 40 for installation.
Working principle: the center 20 is propped against a surface to be drilled, and the drilling machine is driven to drive the drill bit to conduct drilling movement. During the drilling process, the drill always applies an acting force to the surface to be perforated, and the perforated surface always applies pressure to the center 20, so that the center 20 can overcome the acting force of the gas spring 10 to retract the gas spring 10. Finally, after the drilling is finished, the drill bit is separated from the perforated surface, and after the pressure applied by the perforated surface to the center 20 disappears, the center 20 is reset under the action of the gas spring 10 due to the acting force of the gas spring 10.
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.
