Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a fixed-distance drilling device for handle processing, including a frame 1. A lead screw at the front end of the rotating frame 1 controls the pressure plate at the front end of the frame 1 to move backward and clamp the handle. A vertically movable seat 2 is slidably connected to the middle of the frame 1. Two drill spindle seats 3 are slidably connected to the front end of the movable seat 2. A main spindle motor 4 is provided on the front side of each of the two drill spindle seats 3. When the main spindle motor 4 is running, its output shaft drives the drill bit to rotate. The movable seat 2 drives the main spindle motor 4 to move downward through the drill spindle seats 3. The two main spindle motors 4 perform drilling processing on both ends of the handle. It also includes a bidirectional lead screw 19, which is rotatably connected to the front side of the movable seat 2. Both drill spindle seats 3 are threadedly connected to the bidirectional lead screw 19. Rotating the bidirectional lead screw 19... Rod 19 drives the two drill spindle seats 3 to move in opposite directions along the moving seat 2. The upper surface of the left drill spindle seat 3 is provided with a connecting strip 5, and the upper surface of the connecting strip 5 is provided with a scale 6. The upper surface of the right drill spindle seat 3 is provided with a locking assembly, which is used to control the locking of the connecting strip 5 and the moving seat 2. Two positioning pins 14 that can move synchronously in opposite directions are installed at the front end of the frame 1. The handle is placed between the two positioning pins 14. The locking assembly includes a locking seat 7, a pressure plate 8, and a hand bolt 9. The locking seat 7 is set on the upper surface of the right drill spindle seat 3. The connecting strip 5 is slidably connected to the locking seat 7. The pressure plate 8 is slidably connected inside the locking seat 7. The rear end of the pressure plate 8 extends out of the rear end of the locking seat 7 and is set to cooperate with the moving seat 2. The front end of the pressure plate 8 is matched with the connecting strip 5. The locking seat 7 is threaded with a hand-operated bolt 9 at its upper end. The lower end of the hand-operated bolt 9 is rotatably connected to a semi-circular groove on the upper surface of the pressure plate 8. When the hand-operated bolt 9 is loosened, it no longer presses down on the pressure plate 8. The lower surface of the pressure plate 8 is provided with a polyurethane sheet 10. The pressure plate 8 presses the connecting strip 5 and the moving seat 2 together through the polyurethane sheet 10. Under pressure, the polyurethane sheet 10 has a large friction with the connecting strip 5 and the moving seat 2, thereby achieving the positioning and locking of the two drill spindle seats 3. A pin 11 is provided in the middle of the pressure plate 8. The pin 11 is located inside the locking seat 7 and prevents the pressure plate 8 from falling off. The zero mark of the scale 6 is coplanar with the axis of the left spindle motor 4, and the axis of the right spindle motor 4 is coplanar with the left side of the locking seat 7. The scale 6 passes through the locking seat 7. The moving seat 2 on the left side drives the connecting bar 5 and the scale 6 to move synchronously. The connecting bar 5 and the scale 6 slide relative to the locking seat 7. Thus, the distance between the two main spindle motors 4 can be determined according to the position of the left side of the locking seat 7 and the scale 6, which facilitates the control of the drilling spacing. The rear end of the bottom of the frame 1 is rotatably connected to two meshing gears 12. The lower surface of each gear 12 is provided with a lever 13. The lower end of each of the two positioning pins 14 is provided with a sliding column 15 through a rectangular piece. The sliding column 15 is slidably connected to the vertically corresponding lever 13. When the lever 13 is turned, the lever 13 drives the gear 12 to rotate around its own axis. The two gears 12 mesh, and the two levers 13 will rotate in opposite directions with the same amplitude.The long sliding groove in the middle of the lever 13 slides relative to the sliding column 15. The sliding column 15 drives the positioning pin 14 to slide along the sliding hole in the middle of the frame 1. At the same time, the two positioning pins 14 move synchronously in opposite directions. The center point between the two gears 12 and the center point between the two spindle motors 4 are longitudinally coplanar, which can ensure that the handle is placed horizontally in the center. It also includes a stud 16, which is set at the lower end of the right sliding column 15. The lower end of the stud 16 is threaded with a nut 17. After the two positioning pins 14 are adjusted, they are tightened. Nut 17 moves upward under the action of stud 16, pressing the right-side lever 13, thus restricting the relative sliding of slide pin 15 and lever 13, and locking the two positioning pins 14. An electric push rod 20 is provided at the upper end of the frame 1. The telescopic end of the electric push rod 20 is fixedly connected to the upper surface of the movable seat 2. The input end of the electric push rod 20 is electrically connected to the output end of the control switch group 18. When the electric push rod 20 rotates, the movable seat 2 driven by the electric push rod 20 slides downward along the frame 1.

[0021] It also includes a control switch group 18, which is located on the right side of the frame 1. The input end of the spindle motor 4 is electrically connected to the output end of the control switch group 18, and the input end of the control switch group 18 is electrically connected to an external power supply. The control switch group 18 facilitates the control of electrical appliances.

[0022] The working principle of the fixed-distance drilling device for handle processing provided by this utility model is as follows: In use, the handle is placed between two positioning pins 14. Then, the screw at the front end of the frame 1 is rotated to control the pressure plate at the front end of the frame 1 to move backward and clamp the handle. Then, the control switch group 18 is adjusted, the spindle motor 4 operates, and the output shaft of the spindle motor 4 drives the drill bit to rotate. The electric push rod 20 operates, and the moving seat 2 driven by the electric push rod 20 slides downward along the frame 1. The moving seat 2 drives the spindle motor 4 to move downward through the drill spindle seat 3. The two spindle motors 4 perform drilling processing on both ends of the handle. When the size of the handle changes... After the changes and spatial variations occur, the distance between the two spindle motors 4 is adjusted. During adjustment, the hand-operated bolt 9 is loosened, and the hand-operated bolt 9 is no longer pressing down on the pressure plate 8. Then, the double-acting screw 19 is rotated, which drives the two drill spindle seats 3 to move in opposite directions along the moving seat 2. The left moving seat 2 drives the connecting strip 5 and the scale 6 to move synchronously. The connecting strip 5 and the scale 6 slide relative to the locking seat 7. Thus, the distance between the two spindle motors 4 can be determined based on the position of the left side of the locking seat 7 and the scale 6, facilitating the control of the drilling spacing. After adjustment, the hand-operated bolt is tightened. 9. Press down the pressure plate 8 with the hand-operated bolt 9. The pressure plate 8 presses the connecting strip 5 and the moving seat 2 together through the polyurethane sheet 10. Under pressure, the polyurethane sheet 10 has a large friction with the connecting strip 5 and the moving seat 2, which can achieve the positioning and locking of the two drill spindle seats 3. Then loosen the nut 17, and the nut 17 separates from the right-side lever 13. Then turn the lever 13, and the lever 13 drives the gear 12 to rotate around its own axis. The two gears 12 mesh and connect, and then the two levers 13 will rotate in opposite directions with the same amplitude. The long sliding groove in the middle of the lever 13 and the sliding column 15 slide relative to each other. When the slide column 15 moves, the positioning pin 14 slides along the sliding hole in the middle of the frame 1. At the same time, the two positioning pins 14 move synchronously in opposite directions. The center point between the two gears 12 and the center point between the two main shaft motors 4 are longitudinally coplanar, which can ensure that the handle is placed horizontally in the center. After the two positioning pins 14 are adjusted, tighten the nut 17. The nut 17 moves upward under the action of the stud 16. The nut 17 presses the right-side lever 13, thereby restricting the relative sliding between the slide column 15 and the lever 13, which can lock the two positioning pins 14. Then, the handle is centered and positioned by the positioning pins 14.

[0023] It is worth noting that the spindle motor 4 and electric actuator 20 disclosed in the above embodiments can be freely configured according to the actual application scenario. The spindle motor 4 can be a spindle motor with model LD42WS 250W, and the electric actuator 20 can be an electric actuator with model LX700. The control switch group 18 is provided with switch buttons that correspond one-to-one with the spindle motor 4 and the electric actuator 20 for controlling their switching operation.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
