Detailed Implementation

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

[0018] like Figures 1 to 15 As shown, the drilling and tapping device for door and window handles of the present invention includes a worktable 1, a first driving mechanism 2, a second driving mechanism 3, a fixing mechanism 4, and a moving mechanism 5. The first driving mechanism 2, the second driving mechanism 3, the fixing mechanism 4, and the moving mechanism 5 are disposed on the worktable 1. The first driving mechanism 2 is provided with a drill bit assembly 6, and the second driving mechanism 3 is provided with a tap assembly 7. The fixing mechanism 4 is disposed at the lower end of the first driving mechanism 2 and the second driving mechanism 3, and is mounted on the moving mechanism 5. A controller 8 is also provided on the worktable 1. The driving principle of the first driving mechanism 2 and the second driving mechanism 3 can adopt existing technology, so it will not be described in detail here.

[0019] The first drive mechanism 2 drives the drill bit assembly 6 to rotate, and the second drive mechanism 3 drives the tap assembly 7 to rotate. The drill bit assembly 6 is used to drill holes in the handle, while the tap assembly 7 is used to tap the handle after drilling. The fixing mechanism 4 is used to clamp the handle, and the moving mechanism 5 is used to move the fixing mechanism 4. The fixing mechanism 4 moves back and forth between the first drive mechanism 2 and the second drive mechanism 3 through the moving mechanism 5, thereby changing the position of the fixing mechanism 4 and moving the handle to the lower end of the first drive mechanism 2 and the lower end of the second drive mechanism 3.

[0020] The tap assembly 7 is provided with a rotating shaft 55, a mounting piece 9, a tap piece 10, a retaining piece 11, an elastic piece 12, a movable piece 13 and a spring 14. The mounting piece 9 is connected with the rotating shaft 55, the retaining piece 11 is arranged on the mounting piece 9, the elastic piece 12, the movable piece 13 and the spring 14 are arranged in the middle of the retaining piece 11, the tap piece 10 passes through the mounting piece 9, pushes the spring 14 and is inserted into the middle of the movable piece 13 to contact the rotating shaft 55.

[0021] The rotating shaft 55 is kept connected with a driving piece in the second driving mechanism 3, the driving piece can be a motor, and a cylinder can also be arranged in the second driving mechanism 3 to drive the tap assembly 7 to move up and down.

[0022] The mounting piece 9 is connected with the rotating shaft 55 in a threaded manner, so that the mounting piece 9 rotates together with the rotating shaft 55. The upper end of the tap piece 10 passes through the mounting piece 9 to contact and connect with the rotating shaft 55, so that the tap piece 10 rotates together with the rotating shaft 55.

[0023] The retaining piece 11 is arranged in the middle of the mounting piece 9 and is connected with the lower end of the rotating shaft 55 through the mounting piece 9, so that the upper end of the retaining piece 11 contacts the rotating shaft 55, thereby limiting the position of the retaining piece 11 and avoiding the movement of the retaining piece 11 in the mounting piece 9.

[0024] The elastic piece 12 is used to push the movable piece 13, so that the movable piece 13 is pushed by the elastic force and needs to be subjected to an elastic force greater than that of the elastic piece 12 to move in the middle of the retaining piece 11. The elastic piece 12 pushes the movable piece 13, so that the limiting groove 15 on the movable piece 13 cooperates with the limiting protrusion 16 on the tap piece 10 to limit the position of the tap piece 10. Since multiple limiting protrusions 16 are arranged on the tap piece 10, the distance between the tap piece 10 and the mounting piece 9 can be changed when the limiting protrusions 16 at different positions are limited by the limiting grooves 15, so as to adapt to different depths of drilling and tapping. When the limiting protrusion 16 and the limiting groove 15 are separated, the tap piece 10 can be removed, thereby facilitating the replacement of other tap pieces 10.

[0025] The retaining piece 11 is composed of a first outer shell 17 and a second outer shell 18, the middle of the first outer shell 17 and the second outer shell 18 is provided with a blocking plate 19, the movable piece 13 and the elastic piece 12 are arranged on the upper end of the blocking plate 19, the spring 14 is arranged on the lower end of the blocking plate 19, the middle of the movable piece 13 forms a through region 20, and the tap piece 10 is inserted into the through region 20 to contact the rotating shaft 55.

[0026] The first movable chamber 21 is located at the upper end of the baffle 19, and the second movable chamber 22 is located at the lower end of the baffle 19. The middle of the baffle 19 is provided with a first positioning opening 23, and the first and second housings 17 and 18 are provided with a second positioning opening 24. The inner diameters of the first and second positioning openings 23 and 24 are equal. The diameter of the insertion rod 25 is smaller than the inner diameters of the first and second positioning openings 23 and 24, so that the insertion rod 25 can pass through the first and second positioning openings 23 and 24.

[0027] The elastic member 12 pushes the movable member 13, and the inner wall of the through region 20 of the movable member 13 is in contact with the tap member 10 for limiting. The elastic member 12 is composed of a contact section 26, a connecting section 27 and an arc section 28. The elastic region 29 is formed between the contact section 26 and the arc section 28. The contact section 26 is provided with a fixing hole 31 matched with a fixing block 30. The elastic member 12 is compressed under force, so that the elastic region 29 is reduced, the contact section 26 is close to the arc section 28, and the elastic potential energy is generated to facilitate the resetting of the movable member 13.

[0028] The spring 14 is in an inverted conical shape, and the upper end of the spring 14 is larger in diameter than the lower end. The upper end of the spring 14 forms a first circular hole 32, and the lower end forms a second circular hole 33. The diameter of the first circular hole 32 is larger than that of the second circular hole 33. Since the spring 14 is in an inverted conical shape, the first circular hole 32 and the second circular hole 33 are in a gradually reduced state. The diameter of the first circular hole 32 is larger than that of the insertion hole 34, and the diameter of the second circular hole 33 is smaller than that of the insertion hole 34. However, since the first circular hole 32 and the second circular hole 33 are in a gradually reduced state, there is a portion matched with the inner diameter of the insertion hole 34 between the first circular hole 32 and the second circular hole 33. This portion cannot pass through the insertion hole 34. As shown in the figure, the spring 14 is in a slightly compressed state at this time, and a part of the lower end of the spring 14 protrudes out of the insertion hole 34. Figure 15

[0029] The insertion rod 25 on the tap member 10 passes through the second circular hole 33 and is inserted into the middle of the spring 14. The lower end of the spring 14 is in contact with the connection part of the insertion rod 25 and the pushing rod 35. The connection part of the insertion rod 25 and the pushing rod 35 forms a pushing surface 36. The spring 14 is pushed by the pushing surface 36, and the spring 14 is kept compressed. The insertion rod 25 continues to move to the upper end, so that the insertion rod 25 is inserted into the positioning hole 37, and the positioning rod 38 is inserted into the square hole 39 in correspondence. Since the square hole 39 and the positioning rod 38 are matched, the rotating shaft 55 can drive the tap member 10 to rotate.

[0030] ​The first pressing hole 52 is arranged on the mounting piece 9, the pressing piece 41 is arranged in the through hole 40, the pressing piece 41 is connected with the movable piece 13 through the first shell 17, the pressing piece 41 is pressed, the movable piece 13 is kept to push the elastic piece 12 to be deformed under the force, the inner wall of the through area 20 is separated from the tap piece 10. The bottom of the mounting piece 9 is provided with an insertion hole 34, and the tap piece 10 is inserted into the through area 20 through the insertion hole 34.

[0031] The first external thread 42 is arranged on the rotating shaft 55, the middle of the mounting piece 9 forms a mounting area 43, the first internal thread 40 matched with the first external thread 42 is arranged in the mounting area 43. The middle of the rotating shaft 55 is provided with a positioning hole 37, and the positioning rod 38 is arranged in the positioning hole 37. The cross section of the positioning rod 38 is square.

[0032] The tap piece 10 is composed of a tap rod 44, a pushing rod 35 and an insertion rod 25. The diameter of the tap piece 10 is greater than that of the pushing rod 35, and the diameter of the pushing rod 35 is greater than that of the insertion rod 25. The insertion rod 25 is arranged in the positioning hole 37, the middle of the insertion rod 25 forms a square hole 39 matched with the positioning rod 38, and a plurality of limiting protrusions 16 are arranged on the insertion rod 25.

[0033] The movable piece 13 is composed of a first arc-shaped part 45 and a second arc-shaped part 46. The diameter of the first arc-shaped part 45 is greater than that of the second arc-shaped part 46. The middle of the first arc-shaped part 45 forms a first through chamber 47, and the middle of the second arc-shaped part 46 forms a second through chamber 48. The inner wall of the second through chamber 48 is provided with a limiting groove 15 matched with the limiting protrusion 16.

[0034] The first arc-shaped part 45 is provided with a mounting protrusion 49 matched with the pressing piece 41, and the second arc-shaped part 46 is provided with a fixed block 30.

[0035] The pressing piece 41 is composed of a pressing rod 50 and a second external thread 51. The first pressing hole 52 matched with the pressing piece 41 is arranged on the mounting piece 9, the second pressing hole 53 matched with the pressing piece 41 is arranged on the first shell 17, and the second internal thread 54 matched with the second external thread 51 is arranged on the mounting protrusion 49.

[0036] When the tap piece 10 is installed, the pressing piece 41 is first pressed, so that the pressing piece 41 pushes the movable piece 13, the movable piece 13 compresses the elastic piece 12, and the movable piece 13 is kept to move. Then the tap piece 10 is inserted, so that the insertion rod 25 on the tap piece 10 is inserted into the positioning hole 37, then the pressing on the pressing piece 41 is cancelled, the limiting groove 15 is kept to limit the limiting protrusion 16, the position of the tap piece 10 is limited by the movable piece 13, and the tap piece 10 is kept from falling. At the same time, the positioning rod 38 and the square hole 39 are matched, so that the rotating shaft 55 drives the tap piece 10 to rotate.

[0037] Since the inner diameter of the first through chamber 47 is larger than the inner diameter of the second through chamber 48, when the movable member 13 is moved toward the elastic member 12, the insertion rod 25 can be kept moving from the second through chamber 48 to the first through chamber 47, so that the limiting protrusion 16 can be kept separated from the limiting groove 15.

[0038] The above description is merely preferred embodiments of the present application, but not to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall fall within the scope of protection of the present application.
