Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a positioning accuracy calibration device for a drilling loading and unloading device. Background Technology

[0002] The existing drilling loading and unloading devices have some shortcomings. They are inconvenient for effective positioning and calibration of the workpiece, which makes it impossible to accurately position the drill hole. This can easily lead to deviations in the drilling position and reduce the drilling quality. Furthermore, after drilling is completed, it is inconvenient to automatically unload the workpiece, which causes problems. Therefore, we propose a positioning accuracy calibration device for drilling loading and unloading devices to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned shortcomings and to propose a positioning accuracy calibration device for a drilling loading and unloading device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A positioning accuracy calibration device for a drilling loading and unloading device includes a frame, on which a conveyor belt for conveying workpieces is provided. A controller is fixedly connected to the front side of the frame, an upper cylinder is fixedly connected to the top of the frame, a mounting plate is fixedly connected to the output shaft of the upper cylinder, a drilling machine is fixedly connected to the bottom of the mounting plate, a bearing plate is rotatably connected to the inner walls of the front and rear sides of the frame, a flipping unloading mechanism is provided between the bearing plate and the frame, a precision positioning mechanism is provided between the mounting plate and the frame, a calibration mechanism is provided on the front and rear sides of the frame, and an unloading positioning plate is fixedly connected to the inner wall of the top of the frame, with a pressure sensor fixedly connected to one side of the unloading positioning plate.

[0006] In a preferred embodiment of this utility model, the precision positioning mechanism includes a rack fixedly connected to one side of the mounting plate and a support plate fixedly connected to the inner wall of the top of the frame. A rotating shaft is rotatably connected to the front side of the support plate, and a gear is fixedly sleeved on the outer side of the rotating shaft. The gear meshes with the rack. A mounting bracket is fixedly connected to the front side of the gear, and a laser positioning pen is fixedly connected to one side of the mounting bracket. The laser positioning pen is located directly below the drilling rig, and a torsion spring is fixedly connected between the gear and the support plate.

[0007] In a preferred embodiment of this invention, the torsion spring is sleeved on the outside of the rotating shaft.

[0008] As a preferred embodiment of the present invention, the calibration mechanism includes two lower cylinders, which are respectively fixedly connected to the front and rear sides of the frame, and a push plate is fixedly connected to the output shaft of the lower cylinder.

[0009] As a preferred embodiment of this invention, both push plates are slidably connected to the top of the support plate.

[0010] In a preferred embodiment of this utility model, the tilting and unloading mechanism includes a housing fixedly connected to the inner wall of the frame. A servo motor is fixedly connected to one side of the housing, and a drive bevel gear is fixedly connected to the output shaft of the servo motor. Threaded rods are rotatably arranged on the top and bottom inner walls of the housing. A driven bevel gear is fixedly sleeved on the outer side of the threaded rod. The drive bevel gear meshes with the driven bevel gear. A lifting plate is threadedly sleeved on the outer side of the threaded rod. Two connecting rods are fixedly connected to the top of the lifting plate. The top ends of the two connecting rods are fixedly connected to the same horizontal plate. A cylinder is fixedly sleeved inside the horizontal plate. Two frames are fixedly connected to the bottom of the bearing plate, and the cylinder is slidably sleeved within the two frames.

[0011] In a preferred embodiment of this invention, the lifting plate is slidably fitted inside the housing.

[0012] As a preferred embodiment of this utility model, a feed plate is fixedly connected inside the frame, and the feed plate cooperates with the bearing plate.

[0013] In this utility model, the positioning accuracy calibration device for a drilling loading and unloading device can transport the workpiece to the right onto the carrier plate via a conveyor belt. Based on the laser beam emitted by the laser positioning pen, when the workpiece's drilling position is aligned left-right with the laser beam, the conveyor belt is shut off to stop transporting. Depending on the front-to-back position of the drilling hole, two lower cylinders drive the push plates forward or backward, adjusting the hole's position so that it is directly aligned with the laser beam, thus achieving precise positioning. Simultaneously, the two push plates clamp the workpiece, improving stability during drilling. Then, the upper cylinder drives the mounting plate and drilling machine downwards, which in turn drives the rack downwards. The torsion spring is initially in its initial state... In the torsional energy storage state, because there is sufficient distance between the drill bit and the laser positioning pen, the downward movement of the rack can drive the gear, mounting bracket and laser positioning pen to deflect to the left with enough position without hindering the downward movement of the drill. As it continues to move downward, the rack does not contact the gear. At this time, under the torque of the torsion spring, it will continue to drive the gear, mounting bracket and laser positioning pen to deflect to the left by 90 degrees. Then the drill continues to move downward to drill the workpiece. After drilling is completed, the upper cylinder is activated in reverse, so that the drill, mounting plate and rack move upward and reset. At this time, the rack and gear mesh and drive the mounting bracket and laser positioning pen to reverse to directly below the drill for the next positioning of the workpiece.

[0014] In this utility model, the positioning accuracy calibration device of the drilling loading and unloading device starts two lower cylinders in reverse, so that the push plate does not clamp and fix the workpiece. The workpiece continues to be transported by the conveyor belt and moves to the right until it contacts the pressure sensor and the unloading positioning plate. At this time, the pressure sensor is pressed and sends a signal to the controller. The controller shuts off the conveyor belt and starts the servo motor. The servo motor drives the rotation of the active bevel gear, which drives the rotation of the driven bevel gear and the threaded rod. The threaded rod drives the lifting plate, connecting rod, horizontal plate and cylinder to move down. The cylinder drives the two frames and the bearing plate to deflect downward to the position aligned with the unloading plate. At this time, the workpiece is squeezed and slides out along the slope of the bearing plate and the unloading plate for unloading.

[0015] This utility model has a reasonable structural design. By setting up a laser positioning pen and a precision positioning mechanism, the drilling position of the workpiece can be accurately positioned, improving the accuracy of drilling and avoiding deviation in drilling position that would reduce drilling quality. After drilling is completed, the conveyor belt transports the workpiece to a position where it contacts the pressure sensor and the unloading positioning plate. At this point, the servo motor can drive the bearing plate to flip down to a position aligned with the unloading plate, so that the workpiece can slide out and be unloaded, making unloading more convenient and efficient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A positioning accuracy calibration device for a drilling loading and unloading device includes a frame 1, a conveyor belt 6 for conveying workpieces on the frame 1, a controller 2 fixedly connected to the front side of the frame 1, an upper cylinder 3 fixedly connected to the top of the frame 1, an mounting plate 4 fixedly connected to the output shaft of the upper cylinder 3, a drilling machine 5 fixedly connected to the bottom of the mounting plate 4, a bearing plate 12 rotatably connected to the inner walls of the front and rear sides of the frame 1, a flipping unloading mechanism 7 between the bearing plate 12 and the frame 1, a precision positioning mechanism 9 between the mounting plate 4 and the frame 1, a calibration mechanism on the front and rear sides of the frame 1, an unloading positioning plate 11 fixedly connected to the inner wall of the top of the frame 1, and a pressure sensor 8 fixedly connected to one side of the unloading positioning plate 11.

[0023] Furthermore, refer to Figures 1-3 The precision positioning mechanism 9 includes a rack 97 fixedly connected to one side of the mounting plate 4 and a support plate 91 fixedly connected to the inner wall of the top of the frame 1. A rotating shaft 94 is rotatably connected to the front side of the support plate 91. A gear 93 is fixedly sleeved on the outer side of the rotating shaft 94. The gear 93 meshes with the rack 97. A mounting bracket 95 is fixedly connected to the front side of the gear 93. A laser positioning pen 96 is fixedly connected to one side of the mounting bracket 95. The laser positioning pen 96 is located directly below the drill rig 5. A torsion spring 92 is fixedly connected between the gear 93 and the support plate 91. The torsion spring 92 is sleeved on the outer side of the rotating shaft 94. The calibration mechanism includes two lower cylinders 10. The two lower cylinders 10 are fixedly connected to the front and rear sides of the frame 1, respectively. A push plate 13 is fixedly connected to the output shaft of the lower cylinder 10. Both push plates 13 are slidably connected to the top of the bearing plate 12.

[0024] Using the above scheme: the workpiece can be conveyed to the right and loaded onto the bearing plate 12 via the conveyor belt 6. When the workpiece's drilling position aligns with the laser beam emitted by the laser positioning pen 96, the conveyor belt 6 is shut off to stop conveying. Depending on the front-to-back position of the drilling hole, the push plate 13 can be moved forward or backward by the two lower cylinders 10, thereby adjusting the front-to-back position of the drilling hole to ensure it is directly aligned with the laser beam, achieving precise positioning. Simultaneously, the clamping of the workpiece by the two push plates 13 improves the stability during drilling. Then, the upper cylinder 3 drives the mounting plate 4 and the drilling machine 5 to move downwards. The mounting plate 4 drives the rack 97 to move downwards. The torsion spring 92 is initially in a torsional energy storage state. Because the drill bit of the drilling machine 5 and the laser beam... Sufficient spacing between the laser positioning pens 96 allows the downward movement of the rack 97 to drive the gear 93, mounting bracket 95, and laser positioning pen 96 to deflect to the left with enough space without obstructing the downward movement of the drill 5 for drilling. As the downward movement continues, the rack 97 no longer engages with the gear 93. At this point, under the torque of the torsion spring 92, the gear 93, mounting bracket 95, and laser positioning pen 96 will continue to deflect to the left by 90 degrees. Then, the drill 5 continues to move downward to drill the workpiece. After drilling is completed, the upper cylinder 3 is activated in reverse, causing the drill 5, mounting plate 4, and rack 97 to move upward and reset. At this point, the rack 97 engages with the gear 93 and drives the mounting bracket 95 and laser positioning pen 96 to reverse to directly below the drill 5 for the next workpiece positioning.

[0025] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 The flipping and unloading mechanism 7 includes a housing 72 fixedly connected to the inner wall of the frame 1. A servo motor 73 is fixedly connected to one side of the housing 72. A drive bevel gear 74 is fixedly connected to the output shaft of the servo motor 73. Threaded rods 76 are rotatably arranged on the top and bottom inner walls of the housing 72. A driven bevel gear 75 is fixedly sleeved on the outer side of the threaded rod 76. The drive bevel gear 74 meshes with the driven bevel gear 75. A lifting plate 77 is threadedly sleeved on the outer side of the threaded rod 76. Two connecting rods 78 are fixedly connected to the top of the lifting plate 77. The top ends of the two connecting rods 78 are fixedly connected to the same horizontal plate 79. A cylinder 71 is fixedly sleeved inside the horizontal plate 79. Two frames 70 are fixedly connected to the bottom of the bearing plate 12. The cylinder 71 is slidably sleeved inside the two frames 70. The lifting plate 77 is slidably sleeved inside the housing 72.

[0026] Using the above scheme: The workpiece continues to be conveyed by the conveyor belt 6 and moves to the right until it contacts the pressure sensor 8 and the unloading positioning plate 11. At this time, the pressure sensor 8 is under pressure and sends a signal to the controller 2. The controller 2 shuts off the conveyor belt 6 and starts the servo motor 73. The servo motor 73 drives the rotation of the active bevel gear 74. The active bevel gear 74 drives the rotation of the driven bevel gear 75 and the threaded rod 76. The threaded rod 76 drives the lifting plate 77, the connecting rod 78, the horizontal plate 79 and the cylinder 71 to move downward. The cylinder 71 drives the two frames 70 and the bearing plate 12 to deflect downward to the position aligned with the unloading plate 14. At this time, the workpiece is squeezed and slides out along the slope of the bearing plate 12 and the unloading plate 14 for unloading.

[0027] Furthermore, a feed plate 14 is fixedly connected inside the frame 1. The feed plate 14 cooperates with the bearing plate 12 to facilitate the sliding out and feeding of the workpiece.

[0028] In this invention, the workpiece is placed on the conveyor belt 6, which transports the workpiece to the right onto the support plate 12. Based on the laser beam emitted by the laser positioning pen 96, when the workpiece's drilling position aligns with the laser beam, the conveyor belt 6 is shut off to stop transporting. Depending on the drilling position, the two lower cylinders 10 can move the push plate 13 forward or backward, thus adjusting the drilling position to ensure it is directly aligned with the laser beam, achieving precise positioning. Simultaneously, the two push plates 13 clamp the workpiece, improving drilling stability. Then, the upper cylinder 3 moves the mounting plate 4 and the drill 5 downwards, causing the rack 97 to move downwards. The torsion spring 92 is initially in a torsional energy storage state. Sufficient clearance exists between the drill bit 5 and the laser positioning pen 96, allowing the downward movement of the rack 97 to drive the gear 93, mounting bracket 95, and laser positioning pen 96 to deflect to the left with sufficient space without obstructing the downward movement of the drill 5. As the downward movement continues, the rack 97 no longer engages with the gear 93. At this point, under the torque of the torsion spring 92, the gear 93, mounting bracket 95, and laser positioning pen 96 will continue to deflect to the left by 90 degrees. Then, the drill 5 continues to move downward to drill the workpiece. After drilling is completed, the upper cylinder 3 is activated in reverse, causing the drill 5, mounting plate 4, and rack 97 to move upward and reset. At this point, the rack 97 engages with the gear 93 and drives the mounting bracket 95 and laser positioning pen 96 to reverse to directly below the drill 5 for the next workpiece positioning.

[0029] The two lower cylinders 10 are activated in reverse, so that the push plate 13 does not clamp or fix the workpiece. The workpiece continues to be conveyed by the conveyor belt 6 and moves to the right until it contacts the pressure sensor 8 and the unloading positioning plate 11. At this time, the pressure sensor 8 is pressurized and sends a signal to the controller 2. The controller 2 shuts off the conveyor belt 6 and starts the servo motor 73. The servo motor 73 drives the rotation of the active bevel gear 74. The active bevel gear 74 drives the rotation of the driven bevel gear 75 and the threaded rod 76. The threaded rod 76 drives the lifting plate 77, the connecting rod 78, the horizontal plate 79 and the cylinder 71 to move downward. The cylinder 71 drives the two frames 70 and the bearing plate 12 to deflect downward to the position aligned with the unloading plate 14. At this time, the workpiece is squeezed and slides out along the slope of the bearing plate 12 and the unloading plate 14 for unloading.
