Detailed implementation manner

[0017] Please refer to Figures 1 - 10 , the present invention provides a technical solution: an automotive door lock sleeve universal automatic tapping device, including a base 1, a turntable 2 is installed above the base 1, a feeding member 3 is rotatably connected to the turntable 2, an output shaft of the feeding member 3 is fixedly connected to a sleeve 4, a rotating member 5 is sleeved in the sleeve 4, and a rotating seat 6 is fixedly connected to an output shaft of the rotating member 5; An adjusting mechanism is provided on the base 1, and the adjusting mechanism is used to adjust the position of the turntable 2; A clamping mechanism is provided on the rotating seat 6, and the clamping mechanism is used to automatically clamp the tap on the rotating seat 6; A detection mechanism is provided on the sleeve 4, the detection mechanism includes a first spring 7 fixed in the sleeve 4, and the front end of the first spring 7 is fixedly connected to the rotating member; a touch sensor 8 is fixedly connected behind the rotating member in the sleeve 4; a relaxation assembly is provided on the sleeve 4, and the relaxation assembly is used to drive the feeding member 3 to drive the sleeve 4 to reset and the sleeve 4 to drive the clamping mechanism to release the damaged tap after the rotating member moves backward relative to the sleeve 4 and touches the touch sensor 8; a replacement assembly is provided above the sleeve 4, and the replacement assembly is used to replace a new tap onto the rotating seat 6 after the clamping mechanism releases the damaged tap; During operation, since the outer shapes of stationary automotive doors are all different and the positions of their door lock sleeves are also different, when using this device for tapping, the position of the turntable 2 is adjusted by starting the adjusting mechanism, and then the feeding member 3 is driven to rotate relative to the turntable 2 by a certain angle, so that the tap can be in the position directly facing the door lock sleeve for tapping, thereby enabling the tap to tap at various different angular positions and achieving the effect of being able to adapt to tapping of various different specifications of door lock buckles; When the tap is adjusted to the tapping direction, the feeding member 3 is activated to drive the sleeve 4 to approach the tapping position. The sleeve 4 drives the rotating member 5 and the tap clamped on the rotating member 5 to move through the first spring 7. While the sleeve 4 is moving, the rotating member 5 is activated. The rotating member 5 drives the tap to rotate through the rotating seat 6. When the tap fits the tapping position of the car door lock sleeve, the tap can smoothly complete tapping under the cooperation of the feeding member 3 and the rotating member. Since the tap is a vulnerable part with a short service life, after the tap is damaged and cannot tap normally, when the feeding member 3 continues to feed, the tap cannot move forward, resulting in the rotating member moving relative to the sleeve 4 in the sleeve 4 towards the direction of touching the touch sensor 8. When the rotating member touches the touch sensor 8, the touch sensor 8 controls the feeding member 3 to stop feeding and drives the sleeve 4 to reset. After the sleeve 4 resets, the loosening assembly will first drive the clamping mechanism to loosen the damaged tap, and the replacement assembly automatically replaces a new tap onto the fixed seat, and the clamping mechanism automatically clamps the new tap, achieving the effect of automatic replacement after the tap is damaged.

[0018] As a further solution of the present invention, the clamping mechanism includes three sliding sleeves 9 fixedly arranged on the rotating seat 6 in a circumferential array. A clamping plate 10 is slidably connected in the sliding sleeve 9. A limiting frame 11 is fixedly connected to the front side position of the sliding sleeve 9. A slider 12 is slidably connected in the limiting frame 11. The slider 12 is connected to the limiting frame 11 through the second spring 13 and a first connecting rod 14 is rotatably connected to the slider 12. The other end of the first connecting rod 14 is rotatably connected to the clamping plate 10. A connecting ring 15 is arranged on the front side of the rotating seat 6. The connecting ring 15 is fixedly connected to the three sliders 12. A clamping component is arranged on the connecting ring 15 and is used for clamping the connecting ring 15 at the position closest to the rotating seat 6 when the three clamping plates 10 clamp the tap. The clamping component includes a rotating ring 16 rotatably connected to the connecting ring 15. Second connecting rods 17 are fixedly connected to the rear positions on the left and right sides of the rotating ring 16. A first clamping block 18 is fixedly connected to the rear end of the second connecting rod 17. Second clamping blocks 19 are rotatably connected to the upper and lower positions of the rotating member where the first clamping block 18 is located. The second clamping blocks 19 are in clamping fit with the first clamping block 18. The two second clamping blocks 19 engaged with the first clamping block 18 are symmetrically arranged and the part of the second clamping block 19 close to the first clamping block 18 is beveled. The second clamping block 19 is connected to the rotating member through a torsion spring and when the second clamping block 19 is not stressed, the second clamping block 19 is parallel to the second connecting rod 17. During operation, refer to Figures 8 - 10When the tap needs to be clamped, the tap is placed between the three clamping plates 10, and then the rotating ring 16 is pushed backward, the rotating ring 16 drives the connecting ring 15 to move backward, and the connecting ring 15 drives the three sliders 12 connected thereto to move backward. When the slider 12 moves backward, it drives the corresponding clamping plate 10 to move toward the center position of the rotating seat 6 through the connecting rod 14; when the three clamping plates 10 move toward the center position of the rotating seat 6 at the same time, they can fit on the surface of the tap and clamp it; when the rotating ring 16 moves backward, the rotating ring 16 drives the two connecting rods 2 17 connected thereto to move backward, and the connecting rod 2 17 drives the clamping block 1 18 to move. When the three clamping plates 10 clamp the tap, the clamping block 1 18 just moves to the position engaged with the clamping block 2 19, and the clamping block 2 19 clamps the clamping block 18, and the three clamping plates 10 keep the tap clamped.

[0019] As a further solution of the present invention, the release assembly includes a push rod 20 symmetrically arranged at the left and right positions of the sleeve 4, and the push rod 20 is fixedly connected to the feed member 3; a rotating plate 21 is symmetrically arranged at the upper and lower sides of the front end of the push rod 20, and the two rotating plates 21 are coaxially fixed to the two clamping blocks 19 respectively; a clamping unit is provided on the rotating member, and the clamping unit is used to clamp the rotating member on the sleeve 4 when the rotating member moves backward relative to the sleeve 4 to fit the touch sensor 8; The engaging unit comprises a frame 22 symmetrically fixed on both sides of the rotating member, the frame 22 and the sleeve 4 are in clearance fit, and a clamping block 3 23 is symmetrically slidably connected to the upper and lower positions in the frame 22, and the two clamping blocks 3 23 are fixedly connected by a spring 3 24; a clamping block 4 25 is fixedly connected to the sleeve 4 at a position directly behind the clamping block 3 23; a push rod 1 26 is fixedly connected to the clamping block 3 23, and a push rod 2 27 fixedly connected to the push rod 1 20 is provided at a position directly behind the push rod 1 26; When working, see Figures 8 - 9When the tap is damaged, the tap cannot tap, and when the feed member 3 feeds, the rotating member will move backward relative to the sleeve 4; when the rotating member moves, it drives the two frames 22 connected to it to move, and the frame 22 drives the two clamping blocks 3 23 located inside it to move; when the rotating frame moves to the position that touches the touch sensor 8, at this time, the clamping block 3 23 in the frame 22 just moves to the position that engages with the clamping block 4 25, and the clamping block 4 25 clamps the clamping block 3 23, and the rotating member remains in the position retracted in the sleeve 4 and does not move, and the feed member 3 starts to drive the sleeve 4 to reset; when the sleeve 4 resets, since the rotating member is in a state of being retracted inside the sleeve 4, the rotating member is in a rear position of its initial position after reset, and during the resetting process of the rotating member, the two rotating plates 21 on the rotating member will be supported and rotated by the push rod 1 20, and the rotating plate 21 drives the connected The connected block 2 19 rotates, and the block 2 19 will be separated from the block 1 18 when it rotates. At this time, under the action of the three springs 1 7, the slider 12 moves forward in the limit frame 11, and the slider 12 drives the clamping plate 10 to separate from the tap through the connecting rod; after the push rod 1 20 pushes open the rotating plate 21, the sleeve 4 drives the rotating part to continue to reset, and the push rod 1 26 on the block 3 23 begins to fit with the push rod 2 27 and under the pressure of the push rod 2 27, the push rod 1 26 moves to the center position of the frame 22; when the sleeve 4 drives the rotating part to completely reset, the two push rods 27 in the frame 22 respectively drive the two block 3 23 to move to the most central position in the frame 22, and the block 3 23 is separated from the block 4 25. At this time, the spring 1 7 bounces the rotating part forward. When the rotating part is bounced to the frontmost position, the released tap will automatically fall down under the action of inertia.

[0020] As a further solution of the present invention, the replacement assembly includes a rod body 28 rotatably connected to the turntable 2, a motor 29 is fixedly connected to the turntable 2 at a position behind the rotation of the rod body 28, and the output shaft of the motor 29 is fixedly connected to the rod body 28; a mounting frame 30 is fixedly connected to the front end of the rod body 28, a tap is clamped in the mounting frame 30, and a push rod 2 31 is fixedly connected to the left and right positions of the rear side of the mounting frame 30, and the distance between the two push rods 2 31 is equal to the distance between the two connecting rods 2 17; When working, see Figure 1 , Figure 5, when the damaged tap falls off the rotating seat 6, the first motor 29 is started at this time to drive the rod body 28 to rotate downward. When the rod body 28 rotates to a position parallel to the sleeve 4, it stops. At this time, the tap on the mounting frame 30 is at the center position of the rotating seat 6 (the mounting frame 30 drives the tap to move through friction); by starting the feeding member 3 to drive the rotating member to move forward, the rotating member drives the rotating seat 6 to move forward until it fits with the tap mounting end. At this time, both sides of the rotating ring 16 are in contact with the two second ejector rods 31; as the rotating seat 6 continues to move forward, the tap will move forward in the mounting frame 30. Since the second ejector rod 31 abuts against the rotating ring 16, the rotating ring 16 will drive the first clamping block 18 backward relative to the rotating seat 6. When the first clamping block 18 moves to a position where it engages with the second clamping block 19, the first motor 29 is started at this time to drive the rod body 28 to rotate upward (the tap mounting end is usually not cylindrical, so when tapping, it is only necessary to clamp the tap to prevent the tap from rotating relative to the rotating seat 6, and it is not necessary to clamp it tightly).

[0021] As a further solution of the present invention, the adjusting mechanism includes a first sliding seat 32 that is slidably connected to the base 1 in the forward direction, and a second sliding seat 33 is laterally slidably connected to the first sliding seat 32; a plurality of second motors 34 are fixedly connected to both the base 1 and the first sliding seat 32; a plurality of lead screws 35 parallel to their sliding directions are threadedly connected inside the first sliding seat 32 and the second sliding seat 33, and the output shafts of the plurality of second motors 34 are respectively fixedly connected to the plurality of lead screws 35; a lifting column 36 is fixedly connected to the second sliding seat 33, and the upper end of the lifting column 36 is rotatably connected to the turntable 2; During operation, refer to Figure 1 , Figure 4 , by starting the second motor 34 at the bottom, the lead screw 35 at the bottom can be driven to rotate, and the lead screw 35 at the bottom will drive the first sliding seat 32 and all the structures above the first sliding seat 32 to move back and forth; by starting the second motor 34 at the upper part, the lead screw 35 at the upper part can be driven to rotate, and the lead screw 35 at the upper part will drive the second sliding seat 33 and all the structures above the second sliding seat 33 to move left and right, so as to drive the tap to move arbitrarily on the plane; by starting the lifting column 36 to lift and lower, the tap can be driven to move arbitrarily up and down, and the tap can be driven to move arbitrarily in the horizontal direction through the first sliding seat 32 and the second sliding seat 33; by driving the turntable 2 and the feeding member 3 to rotate, the tap can be adjusted to multiple angles, and then the tap can tap at multiple angles.
