[0015] This type of automatic drilling device features a simple structure, ingenious design, and reasonable layout. It addresses the problems inherent in traditional single-workpiece drilling operations by incorporating a unique structure. It utilizes a vibratory feeder to transport workpieces one by one into the X-axis slideway. A cylinder then pushes the workpieces sliding out of the X-axis slideway into the Y-axis slideway. A stepping feeding mechanism then enables the workpieces to move stepwise within the Y-axis slideway. This motion ensures precise positioning of the workpieces at the drilling station. Once the workpiece reaches the drilling station, it is clamped and positioned by a clamping fixture. Simultaneously, the Z-axis motor descends to perform the drilling operation. After the program is set, this device achieves automated drilling operations with minimal or no manual intervention, effectively improving work efficiency, reducing labor intensity, and ensuring drilling quality. Compared to traditional methods, it offers numerous advantages and is particularly suitable for widespread application in this field, with a very promising market prospect.

[0022] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 6 As shown: An automatic drilling device includes a base 1 as a foundation, on which a vibrating feeder 2 is mounted. An inclined X-axis slide 4 is provided at the outlet of the linear discharge section 3 of the vibrating feeder 2.

A first Y-axis cylinder 8 is also mounted on the support frame 6, and the end of the output shaft of the first Y-axis cylinder 8 corresponds to the outlet end of the X-axis slide rail 4.

[0024] A sensor bracket 9 is installed on the X-axis slide rail 4, and a second sensor 10 is installed on the sensor bracket 9 above the X-axis slide rail 4. The detection station is located directly below the second sensor 10.

[0025] A stepping feeding mechanism is also provided on the support frame 6. The stepping feeding mechanism includes a second Y-axis cylinder 11 fixedly connected to the support frame 6. The working end of the second Y-axis cylinder 11 is connected to a Y-axis slide 12 slidably connected to the support frame 6. A first X-axis cylinder 13 is provided on the Y-axis slide 12. The working end of the first X-axis cylinder 13 is provided with a pin 14. The detection station is located within the movement range of the first X-axis cylinder 13.

[0026] The top of the support frame 6 is equipped with a Z-axis motor 15 capable of longitudinal movement. The axis of the Z-axis motor 15 intersects perpendicularly with the axis of the Y-axis slide rail 5. The intersection point is the drilling station, and a drill bit is connected to the working end of the Z-axis motor 15.

[0027] A second X-axis cylinder 16 is mounted on the support frame 6. A clamping fixture 17 is mounted on the working end of the second X-axis cylinder 16. The clamping fixture 17 corresponds to the drilling station. A third sensor 18 is also mounted on the support frame 6 on the opposite side of the clamping fixture 17.

[0028] An inclined feeding chute 19 is provided at the outlet end of the X-axis slide 4.

[0029] The Z-axis motor 15 is connected to the Z-axis slide plate 20. The top of the Z-axis slide plate 20 is connected to the working end of the Z-axis cylinder 21. At the same time, the Z-axis slide plate 20 is connected to the Z-axis motor mounting plate 22 through the Z-axis slide rail. The Z-axis motor mounting plate 22 is connected to the support frame 6.

[0030] The Z-axis motor mounting plate 22 is movably connected to one side of the right-angle bracket 24 via a pair of Y-axis mounting slide rails 23. A Y-axis adjustment mechanism 25 matching the Z-axis motor mounting plate 22 is provided on the right-angle bracket 24. The other side of the right-angle bracket 24 is movably connected to the main support plate 27 via a pair of X-axis mounting slide rails 26. An X-axis adjustment mechanism 28 matching the right-angle bracket 24 is provided on the main support plate 27. The bottom end of the main support plate 27 is fixedly connected to the support frame 6.

[0031] The Y-axis adjustment mechanism 25 includes a fixed base 29, on which a Y-axis adjustment screw 30 is threadedly connected. The end of the adjustment screw 30 is rotatably connected to the Z-axis motor mounting plate 22. The X-axis adjustment mechanism 28 also includes a fixed base 29, on which an X-axis adjustment screw 31 is threadedly connected. The end of the X-axis adjustment screw 31 is rotatably connected to the right-angle bracket 24.

[0032] The working process of this type of automatic drilling device is as follows: Multiple workpieces 32 that need to be drilled are placed into the vibrating feeder 2. Under the action of the vibrating feeder 2, the workpieces 32 enter the straight discharge section 3 in a specific posture, and after entering the X-axis slide 4 in sequence, they automatically slide from the high position to the low position of the X-axis slide 4 outlet end (i.e., the Y-axis slide 5 inlet end). When the workpiece 32 contacts the side wall of the Y-axis slide 5, the first sensor 7 set here detects the workpiece 32 and sends a signal to the control system. The control system controls the first Y-axis cylinder 8 to move, pushing the workpiece 32 along the axis of the Y-axis slide 5. Then the first Y-axis cylinder 8 is retracted and returns to the initial position, making way for the outlet end of the X-axis slide 4 in the Y-axis direction so that the next workpiece 32 can slide smoothly to this position. (It should be noted that in order to ensure the retraction of the first Y-axis cylinder 8, the outline of its working shaft basically matches the cross-section of the Y-axis slide 5 to prevent the working shaft of the first Y-axis cylinder 8 from jamming after the next workpiece 32 falls.)

[0033] After the first workpiece 32 is pushed into place by the first Y-axis cylinder 8, it moves to the detection station (directly below the second sensor 10). After the second sensor 10 detects the workpiece 32, the control system controls the stepping feeding mechanism to move the workpiece 32 in the Y-axis slide 5 at a distance of one unit each time, until the first workpiece 32 moves to the drilling station. After the third sensor 18 located there detects that a workpiece has moved to this position, the control system controls the second X-axis cylinder 16 to move the clamping fixture 17 toward the workpiece 32, clamping and positioning it. Then the Z-axis motor 15 moves downward, and the drill bit rotates while feeding downward to complete the drilling operation on the workpiece 32.

[0034] After the drilling operation is completed, the Z-axis motor 15 moves upward, the second X-axis cylinder 16 retracts, and after the workpiece 32 regains its degree of freedom, it is pushed into the unloading slide 19 by the workpiece 32 behind it in a stepping motion, and slides into the collection container along the inclined unloading slide 19.

[0035] In the above actions, the various actuators coordinate their actions through the control system to ensure that the sequence and rhythm of each action meet the requirements;

[0036] The working process of the stepping feeding mechanism is as follows: In the initial state, the second Y-axis cylinder 11 is in the retracted state, and the pin 14 corresponds exactly to the detection station. After receiving the signal from the control system, the first X-axis cylinder 13 works first, driving the pin 14 to move and insert it into the hole on the workpiece 32 (this hole is used as the connecting pin hole). After the first X-axis cylinder 13 finishes its action, the second Y-axis cylinder 11 extends and drives the Y-axis slide 12 to move a unit distance (this unit distance is equal to the length of the workpiece 32), thereby pushing the workpiece 32 to move "one step", realizing stepping advancement; after the second Y-axis cylinder 11 moves to the position, the first X-axis cylinder 13 retracts, and then the second Y-axis cylinder 11 retracts, and the stepping feeding mechanism returns to the initial state, waiting for the next operation;

[0037] When the Z-axis motor 15 needs to move downward, the control system sends a signal to the Z-axis cylinder 21, and the Z-axis cylinder directly drives the Z-axis slide plate 20 to move downward relative to the support frame 6.

[0038] In actual operation, the central axis of the Z-axis motor 15 may not match the theoretical machining position. In this case, it is necessary to adjust it in the X-axis and Y-axis directions. The relative position between the main support plate 27 and the right-angle bracket 24 in the X-axis direction is adjusted by rotating the X-axis adjusting screw 31, and the relative position between the right-angle bracket 24 and the Z-axis motor mounting plate 22 is adjusted by rotating the Y-axis adjusting screw 30.
