[0031] Reference Figure 1 The utility model discloses first aspect embodiment's guide bush trepanning machine, it includes: fixed sleeve 100, fixed sleeve 100 is equipped with the through guide hole 110;Sliding member 300, with guide hole 110 sliding cooperation, and sliding member 300 is equipped with the through first axle hole 310, and the axis of first axle hole 310 is parallel to the axis of guide hole 110;Rotary member 600, with first axle hole 310 rotatable cooperation, and with sliding member 300 synchronous relative to guide hole 110 sliding, and rotary member 600 is equipped with second axle hole 610 and driven engagement part, and second axle hole 610 is coaxial with first axle hole 310, and driven engagement part can be cooperated with drill bit 700 or electric drill spindle, makes rotary member 600 can follow drill bit 700 synchronous rotation;Elastic member, elastic member can exert the elastic force opposite to the feed direction of drill bit 700 to sliding member 300.
[0032] When drilling, fixed sleeve 100 is placed in fixture and is fixed, makes the lower surface of fixed sleeve 100 to fit workpiece, starts electric drill, and makes drill bit 700 rotation downward movement, drill bit 700 passes through the second axle hole 610 of rotary member 600, and drives rotary member 600 to rotate, simultaneously, drill bit 700 and rotary member 600 downward movement and drive sliding member 300 to move downward synchronously, while moving downward, elastic member will exert the elastic force opposite to the feed direction of drill bit 700 to sliding member 300, slows down the down-moving speed of drill bit 700, and finally completes drilling steadily.According to the compression amount or the amount of extension of elastic member, the drilling depth of drill bit 700 can be controlled, and the down-moving speed of drill bit 700 can be better controlled to complete drilling with higher precision;Because the existence of fixed sleeve 100 isolates drill bit 700 and fixture, so that drill bit 700 does not contact fixture when drilling, so that fixture is not affected by the abrasion caused by the rotation of drill bit 700, greatly prolongs the service life of fixture.
[0033] In some embodiments of the first aspect of the utility model, reference Figure 1 The guide hole 110 is a cylindrical hole, and the sliding member 300 is a cylindrical structure and is arranged in the guide hole 110.
[0034] Specifically, in some embodiments of the first aspect of the present application, the sliding member 300 and the fixed sleeve 100 are gap fit, which meets the sliding arrangement requirement and ensures that the sliding member 300 does not deflect in the guide hole 110.
[0035] It can be understood that, in some embodiments of the first aspect of the present application, the guide hole 110 is a polygonal hole, and the sliding member 300 is a polygonal structure matched with the guide hole 110 and arranged in the guide hole 110, which also achieves the purpose of sliding arrangement of the sliding member 300 relative to the fixed sleeve 100.
[0036] It can be conceived that, in some embodiments of the first aspect of the present application, the shape of the guide hole 110 and the structural shape of the sliding member 300 can be any suitable shape.
[0037] In some embodiments of the first aspect of the present application, referring to Figure 2 , the driven engagement part of the rotating member 600 is higher than the sliding member 300. When the drill bit 700 cooperates with the driven engagement part to drive the rotating member 600 to rotate, the purpose that the drill bit 700 does not interfere with the sliding member 300 is met.
[0038] In some embodiments of the first aspect of the present application, referring to Figure 1 and Figure 2 , the elastic member is a spring 200, one end of the spring 200 abuts against the fixed sleeve 100, and the other end abuts against the sliding member 300. When the sliding member 300 is driven downward by the drill bit 700, the spring 200 is compressed and generates an upward force, which slows down the feed speed of the drill bit 700. Different compression amounts of the spring 200 result in different depths of the drill bit 700 into the workpiece, which achieves the purpose of drilling holes with different depths and higher precision.
[0039] Specifically, in some embodiments of the first aspect of the present application, the upper end of the spring 200 abuts against the sliding member 300 but does not contact the rotating member 600, and the lower end abuts against the inner wall of the lower end of the fixed sleeve 100. The spring 200 is coaxially arranged with the second shaft hole 610, which ensures that the rotating action of the drill bit 700 and the rotating member 600 is not affected.
[0040] It can be understood that, in some embodiments of the first aspect of the present application, the elastic member is an elastic rope, one end of the elastic rope is fixed to the upper end of the fixed sleeve 100, and the other end is fixed to the upper end of the sliding member 300. When the sliding member 300 moves downward with the drill bit 700, the elastic rope is elongated and generates an upward tension, which slows down the feed speed of the drill bit 700. Different elongation amounts of the elastic rope result in different depths of the drill bit 700 into the workpiece, which achieves the purpose of drilling holes with different depths and higher precision.
[0041] It is conceived that, in some embodiments of the first aspect of the present application, the elastic member can be any elastic component, as long as it can exert an elastic force on the sliding member 300 in the opposite direction of the feed direction of the drill bit 700.
[0042] In some embodiments of the first aspect of the present application, referring to Figure 1 With Figure 2 It also comprises a retainer 400 and a rolling body, the retainer 400 is arranged between the inner wall of the sliding member 300 and the outer wall of the rotating member 600, and the side wall of the retainer 400 is uniformly provided with mounting holes 410; the rolling body is embedded in the mounting hole 410 of the retainer 400, so that the side wall of the rolling body can abut against the inner wall of the sliding member 300 and the outer wall of the rotating member 600 at the same time. When the rotating member 600 rotates with the drill bit 700, the rolling body will roll along the outer wall of the rotating member 600 and the inner wall of the sliding member 300, and the arrangement of the rolling body and the retainer 400 further reduces the wear of the outer wall of the rotating member 600 and the inner wall of the sliding member 300 when they move relative to each other, and improves the service life and structural stability of the entire mechanism.
[0043] Specifically, in some embodiments of the first aspect of the present application, the mounting holes 410 provided in the side wall of the retainer 400 are adapted to the shape of the rolling body.

[0045] In some embodiments of the first aspect of the present application, referring to Figure 1 With Figure 2 The rolling body is a needle roller 500. The needle roller 500 is an elongated rod-shaped cylindrical structure, so that the gap between the outer wall of the rotating member 600 and the inner wall of the sliding member 300 is smaller, further reducing the structural size of the entire device, and allowing a thicker drill bit 700 to be installed when the size of the fixed sleeve 100 is fixed, thereby increasing the drilling range of the device; at the same time, the structure of the needle roller 500 allows the rolling body to roll only along the cylindrical surface, further enhancing the axial load capacity of the rotating member 600 and ensuring the synchronization of the axial movement (up and down movement in the figure) of the rotating member 600 and the sliding member 300.
[0046] It is conceived that the rolling body can be of any shape, as long as it can roll to meet the rotating arrangement of the rotating member 600.
