[0002] With market development and changing consumer demands, the jewelry industry is gradually demonstrating its unique charm and huge market potential, becoming a new favorite for more and more entrepreneurs.

[0003] When making jade bead bracelets in jewelry companies, it is necessary to make beads of the same size. In the bead making process, the jade raw material is first cut into blocks about 5mm larger than the diameter of the target beads. Then, the blocks of jade are placed on the workbench of a bench drill, and the material is cut into small cylindrical pieces by a high-speed rotating drill bit. Finally, the small cylindrical pieces of jade are polished into beads. During the material cutting process with the bench drill, due to the lack of a clamping device for the jade plate, the operator needs to press down on the jade plate with one hand and turn the operating lever of the bench drill with the other hand. As production increases, operators need to operate for long periods of time, resulting in high labor intensity. In addition, the operator needs to press down on the jade plate with their hand each time, which poses a safety hazard of hand injury during the material cutting process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing a cylinder-type semi-automatic drilling machine, which can drill small cylindrical blocks semi-automatically and quickly while ensuring safe operation, effectively improving production efficiency, reducing labor intensity, and featuring ease of use and strong practicality.

[0006] As a further improvement, the pneumatic lifting device includes a first cylinder, a mounting plate, and a connecting plate. The first cylinder is mounted on the drilling machine body via the mounting plate. The output end of the first cylinder is connected to one end of the connecting plate, and the other end of the connecting plate is connected to the spindle sleeve. The air pump controls the first cylinder to drive via a control component.

[0007] Furthermore, the control components include a control switch, a relay, a solenoid valve, a sensor, and a PLC controller.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This utility model discloses a cylinder-type semi-automatic drilling machine. In use, the jade slab with the drilling hole is first placed on the worktable below the hollow drill bit. After aligning it with the desired material removal position, the control switch is pressed to start the machine. The signal is transmitted to the PLC controller, which controls a relay. The relay controls a solenoid valve, causing the air pump to supply air to the first and second cylinders. This causes the output ends of the first and second cylinders to move downwards. The second cylinder pushes the pressure plate downwards to press the jade slab, thus achieving automatic pressing of the jade slab without manual pressing, thereby improving safety and preventing accidents. When the drilling machine spindle is pressed down, the first cylinder moves downward to push the connecting plate. The connecting plate then moves the spindle sleeve downward, which in turn moves the drilling machine spindle downward to achieve material removal. This achieves semi-automatic material removal by pressing down, eliminating the need to manually press the drilling machine's rocker arm and reducing labor intensity. Once the material is pressed down to the set height, the sensor detects this and transmits a signal to the PLC controller. The PLC controller controls the relay, which in turn controls the solenoid valve, causing the first and second cylinders to move upward to reset. This automatically completes the material removal process, effectively improving production efficiency. The system is easy to use and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0020] See Figure 1-2As shown, this utility model discloses a cylinder-type semi-automatic drilling machine, including a drilling machine body 1. The drilling machine body 1 is equipped with a drilling spindle 4, a spindle sleeve 5, a worktable 12, and a spindle drive motor 6. The spindle drive motor 6 is connected to the drilling spindle and drives the drilling spindle 4 to rotate. The drilling spindle 4 is equipped with a hollow drill bit 7 for drilling. The drilling machine body 1 is equipped with a pneumatic lifting device 2 for controlling the up and down movement of the drilling spindle. The drive end of the pneumatic lifting device 2 is connected to the spindle sleeve 5. The worktable 12 is equipped with a protective frame 11, and a pneumatic clamping device 3 for clamping the jade slab is mounted on the protective frame 11. Both the pneumatic lifting device 2 and the pneumatic clamping device 3 are connected to an air pump 19 and a control component. In use, the jade slab with the drilling hole is first placed on the worktable 12 below the hollow drill bit 7. After aligning it with the position to be removed, the control switch 8 is pressed to start the machine. The signal is transmitted to the PLC controller 18, which controls the relay 16. The relay 16 controls... The solenoid valve 17 is activated, allowing the air pump 19 to supply air to the first cylinder 21 and the second cylinder 31. This causes the output ends of the first cylinder 21 and the second cylinder 31 to move downwards. The second cylinder 31 pushes the pressure plate 33 downwards to press the jade slab, thus achieving automatic pressing of the jade slab without manual pressing, thereby improving safety and preventing accidents. At the same time, the downward movement of the first cylinder 21 pushes the connecting plate 23, which in turn drives the spindle sleeve downwards, thereby moving the drill spindle 4 downwards to achieve material removal. This achieves semi-automatic material removal without manual pressing of the drill arm 9, thus reducing labor intensity. When the material is pressed to the set height, the sensor 10 detects this and transmits a signal to the PLC controller 18. The PLC controller 18 controls the relay 16, which in turn controls the solenoid valve 17, causing the first cylinder 21 and the second cylinder 31 to move upwards to reset, thus automatically completing the material removal process and effectively improving production efficiency.

[0021] As a further improvement, the pneumatic lifting device 2 includes a first cylinder 21, a mounting plate 22, and a connecting plate 23. The first cylinder 21 is mounted on the drill body 1 via the mounting plate 22. The output end of the first cylinder 21 is connected to one end of the connecting plate 23, and the other end of the connecting plate 23 is connected to the spindle sleeve 5. The air pump 19 controls the first cylinder 21 to drive it through the control component. The spindle sleeve 5 is slidably mounted on the drill body 1, and the drill spindle 4 is rotatably mounted inside the spindle sleeve 5. This part belongs to the prior art structure and will not be described in detail here. The first cylinder 21 moves downward to push the connecting plate 23, and the connecting plate 23 drives the spindle sleeve to move downward, thereby moving the drill spindle 4 downward to achieve downward pressing and picking, thus realizing semi-automatic downward pressing and picking, thereby reducing labor intensity.

[0022] Furthermore, the control components include a control switch 8, a relay 16, a solenoid valve 17, a sensor 10, and a PLC controller 18. The control switch 8 is mounted on the rocker arm 9 of the drill body 1, and the sensor 10 is mounted on the top of the cylinder rod of the first cylinder 21. The relay 16, the control switch 8, the sensor 10, and the PLC controller 18 are electrically connected. The solenoid valve 17 is electrically connected to the relay 16 and is connected to the first cylinder 21 and the air pump 19. The sensor 10 is a stroke limit micro-motion touch switch, model V-153-1C25. The PLC controller 18 controls the operation of the first cylinder 21 and the second cylinder 31 to achieve automatic pressing and material picking.

[0023] Furthermore, a pressure regulating valve 15 is provided between the solenoid valve 17 and the first cylinder 21 to regulate the pressure of the first cylinder 21 pressing the material downward, thereby meeting the needs of plates of different thicknesses.

[0024] Furthermore, the pneumatic pressing device 3 includes a second cylinder 31, a pressure plate 33, and a bracket 32. The second cylinder 31 is mounted on the protective frame 11 via the bracket 32. The output end of the second cylinder 31 is connected to the pressure plate 33. The second cylinder 31 is connected to the air pump 19 via a solenoid valve 17. When the output end of the second cylinder 31 moves downward, the second cylinder 31 pushes the pressure plate 33 downward to press the jade slab, thereby achieving automatic pressing of the jade slab without the need for manual pressing, avoiding the risk of hand injury, and thus improving safety.

[0025] Furthermore, a support screw 14 is provided at one end of the pressure plate 33. The support screw 14 is installed on the pressure plate 33 by a nut, so that after the other end of the pressure plate 33 presses the plate, the end where the support screw 14 is located plays a supporting role, which makes the pressing balance of the pressure plate 33 better and the pressing more secure.

[0026] Furthermore, the pressure plate 33 is provided with clearance holes 20 to allow space and avoid affecting the operation of the hollow drill bit 7.

[0027] Furthermore, an emergency stop switch 13 is provided on the outer side of the protective frame 11. The emergency stop switch 13 is electrically connected to the PLC controller 18, which plays a role in timely protection. In case of emergency, the entire device can be stopped by pressing the emergency stop switch 13, thereby improving safety.

[0028] In this embodiment, a cylinder-type semi-automatic drilling machine is used by first placing the jade slab with a drilling hole on the worktable 12 below the hollow drill bit 7. After aligning it with the desired material removal position, the control switch 8 is pressed to start the machine. The signal is transmitted to the PLC controller 18, which controls the relay 16. The relay 16 controls the solenoid valve 17, causing the air pump 19 to supply air to the first cylinder 21 and the second cylinder 31. This causes the output ends of the first cylinder 21 and the second cylinder 31 to move downwards. The second cylinder 31 pushes the pressure plate 33 downwards to press the jade slab, thereby achieving automatic pressing of the jade slab without the need for manual pressing, thus improving efficiency. High safety is ensured, preventing accidents. Simultaneously, the first cylinder 21 moves downwards, pushing the connecting plate 23. The connecting plate 23 drives the spindle sleeve downwards, thus moving the drill spindle 4 downwards to achieve material removal by pressing down. This achieves semi-automatic material removal by pressing down, eliminating the need to manually press the drill arm 9, thereby reducing labor intensity. Once the set height is reached, the sensor 10 detects this and transmits a signal to the PLC controller 18. The PLC controller 18 controls the relay 16, which in turn controls the solenoid valve 17, causing the first cylinder 21 and the second cylinder 31 to move upwards to reset, thus automatically completing the material removal by pressing down and effectively improving production efficiency. This utility model provides a cylinder-type semi-automatic drilling machine that can semi-automatically and quickly drill small cylindrical blocks while ensuring safe operation, effectively improving production efficiency and reducing labor intensity. It is convenient to use and highly practical.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
