Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, and more specifically, to a drilling machine direction sensing device. Background Technology

[0002] A drilling machine is a machine and device that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or cavity in the target object through rotary cutting or rotary extrusion. Drilling machines are mainly used to drill holes in precision parts to achieve the desired effect. According to the degree of automation, drilling machines can be divided into semi-automatic drilling machines and fully automatic drilling machines.

[0003] When using a drilling machine, the user determines the drilling direction before starting the drilling operation. However, the user cannot accurately control the drilling direction. During use, the drilling machine is prone to deviation in the drilling direction, causing it to shift left, right, or forward and backward, resulting in tilting. A tilted drilling machine will also cause the drilled hole to deviate from the correct trajectory. Furthermore, during tilted drilling, the drill bit may get stuck due to friction with the tilted hole wall. When the drill bit is stuck, the drilling machine itself may rotate, which can easily cause injury to the user.

[0004] To avoid safety issues caused by the tilting of the drilling machine, a drilling machine orientation sensing device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling machine orientation sensing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a drilling machine orientation sensing device, including a power supply unit, a main control unit, a sensing unit, and an alarm unit. The sensing unit includes a six-axis gyroscope mounted on the drilling machine and peripheral circuitry connected to the six-axis gyroscope. The alarm unit includes an azimuth tilt indicator module and an attitude return indicator module mounted on the surface of the drilling machine. The power supply unit is connected to the main control unit and the six-axis gyroscope. The main control unit is connected to the peripheral circuitry, the azimuth tilt indicator module, and the attitude return indicator module.

[0007] When the drilling machine is powered on, the power supply unit will simultaneously supply power to the main control unit. After the main control unit is powered on, it receives the drilling machine angle offset data detected by the six-axis gyroscope through the peripheral circuit. When the drilling machine is tilted, the main control unit will light up the azimuth tilt indicator module to issue a warning.

[0008] As a further improvement to this technical solution, the six-axis gyroscope includes a chip U1.

[0009] The CLKIN pin of chip U1 is grounded;

[0010] The VLOGIC pin of chip U1 is connected to capacitor C2 and then to a 3.3V terminal. The REGOUT pin of chip U1 is connected to capacitor C4. Capacitor C4 is connected to the AD0 pin and FSYNC pin of chip U1, the other end of capacitor C2, and grounded.

[0011] The VDD pin of chip U1 is connected to capacitor C3 and then to the 3.3V terminal; the GND pin of chip U1 is connected to the other end of capacitor C3 and then grounded.

[0012] The CPOUT pin of the chip U1 is connected to capacitor C1, and capacitor C1 is grounded.

[0013] The SCL pin of chip U1 is connected to resistor R13 and then to the SCL terminal. The SDA pin of chip U1 is connected to resistor R12 and then to the SDA terminal. Resistor R12 is connected to the other end of resistor R13 and then to the 3.3V terminal.

[0014] As a further improvement to this technical solution, the chip U1 is an MPU-6050 six-axis motion processing module.

[0015] As a further improvement to this technical solution, the attitude return indicator module includes a red-green dual-color LED1, and the orientation tilt indicator module includes red-green dual-color LED2, LED3, LED4, and LED5. The red-green dual-color LED1, LED2, LED3, LED4, and LED5 are all disposed on the surface of the drilling machine.

[0016] The middle pins of the red and green dual-color LEDs 1, 2, 3, 4, and 5 are all grounded;

[0017] The two pins of the red-green dual-color LED1 are connected to resistors R21 and R22 respectively. Resistor R21 is connected to the GPIO1 pin of the main control unit, and resistor R22 is connected to the GPIO2 pin of the main control unit.

[0018] The two pins of the red-green dual-color LED2 are connected to resistors R23 and R24 respectively. Resistor R23 is connected to the GPIO3 pin of the main control unit, and resistor R24 ​​is connected to the GPIO4 pin of the main control unit.

[0022] As a further improvement to this technical solution, the red-green dual-color LEDs 2, 3, 4, and 5 are symmetrically distributed around the red-green dual-color LED 1.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] In this drilling machine orientation sensing device, the main control unit uses a six-axis gyroscope to sense changes in the drilling machine's angular velocity and linear acceleration to determine whether the drilling machine is tilted. It then controls the illumination of red and green dual-color LEDs via corresponding GPIO output pins to display the drilling machine's tilt status. During operation, the operator only needs to observe the on / off state of the green dual-color LEDs to determine if the drilling machine is tilted. This solves the problem of the operator being unable to judge the drilling machine's tilt during operation, leading to deviations in the left-right or front-back directions. This improves the drilling accuracy, ensuring the drilling direction does not deviate from the correct position, and also avoids the safety hazard caused by the drill bit getting stuck during drilling.

[0028] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Drilling machines are widely used in industrial manufacturing and large-scale infrastructure construction. During the operation of a drilling machine, the user cannot accurately control the drilling direction, which can easily cause the drilling machine to deviate from its direction and tilt. At the same time, when the drilling machine is tilted, the drill bit is prone to getting stuck, which can cause damage to the user.

[0030] To help operators monitor the drilling machine's operating status at all times and improve work efficiency and drilling success rate, please refer to [link / reference needed]. Figures 1-3 As shown, this embodiment provides a drilling machine orientation sensing device, including a power supply unit, a main control unit, a sensing unit, and an alarm unit. The sensing unit includes a six-axis gyroscope mounted on the drilling machine and peripheral circuits connected to the six-axis gyroscope. The alarm unit includes an azimuth tilt indicator module and an attitude return indicator module mounted on the surface of the drilling machine. The power supply unit is connected to the main control unit and the six-axis gyroscope. The main control unit is connected to the peripheral circuits, the azimuth tilt indicator module, and the attitude return indicator module.

[0031] When the drilling machine is powered on, the power supply unit will simultaneously supply power to the main control unit. After the main control unit is powered on, it receives the drilling machine's angular offset data detected by the six-axis gyroscope through the external circuit. When the drilling machine is tilted, the main control unit will illuminate the azimuth tilt indicator module to issue a warning.

[0032] Furthermore, the six-axis gyroscope includes chip U1.

[0033] The CLKIN pin of chip U1 is grounded;

[0034] Connect the VLOGIC pin of chip U1 to capacitor C2 and then to the 3.3V terminal. Connect the REGOUT pin of chip U1 to capacitor C4. Connect capacitor C4 to the AD0 pin, FSYNC pin, and the other end of capacitor C2 of chip U1 and then to ground.

[0035] The VDD pin of chip U1 is connected to capacitor C3 and then to the 3.3V terminal; the GND pin of chip U1 is connected to the other end of capacitor C3 and then to ground.

[0036] The CPOUT pin of chip U1 is connected to capacitor C1, and capacitor C1 is grounded.

[0037] The SCL pin of chip U1 is connected to resistor R13 and then to the SCL terminal. The SDA pin of chip U1 is connected to resistor R12 and then to the SDA terminal. Resistor R12 is connected to the other end of resistor R13 and then to the 3.3V terminal.

[0038] The VLOGIC pin is the logic pin voltage supply pin for chip U1, which is matched with the 3.3V power supply voltage connected to the VDD pin to ensure the reliability of data transmission and communication measured by chip U1. The SCL and SDA pins are used for IIC communication. In IIC communication, chip U1 is connected to the peripheral circuit through the SCL and SDA pins, and then connected to the main control unit through the peripheral circuit, ensuring the reliability and stability of signal transmission from chip U1 to the main control unit.

[0039] Among them, chip U1 is an MPU-6050 six-axis motion processing module, which integrates not only a three-axis gyroscope but also a three-axis accelerometer. It can output not only three-axis angle information but also three-axis acceleration information. In this embodiment, when the drilling machine has an orientation deviation, the MPU-6050 six-axis motion processing module can detect the changes in the angular velocity and linear acceleration of the drilling machine in a timely manner, thereby achieving high-precision detection of the drilling machine's offset angle.

[0040] The attitude correction indicator module includes a red and green dual-color LED1, and the orientation tilt indicator module includes red and green dual-color LED2, LED3, LED4, and LED5. The red and green dual-color LED1, LED2, LED3, LED4, and LED5 are all set on the surface of the drilling machine.

[0041] The middle pins of the red and green dual-color LEDs 1, 2, 3, 4, and 5 are all grounded;

[0042] The two pins of the red and green dual-color LED1 are connected to resistors R21 and R22 respectively. Resistor R21 is connected to the GPIO1 pin of the main control unit, and resistor R22 is connected to the GPIO2 pin of the main control unit.

[0043] The two pins of the red and green dual-color LED2 are connected to resistors R23 and R24 respectively. Resistor R23 is connected to GPIO pin 3 of the main control unit, and resistor R24 ​​is connected to GPIO pin 4 of the main control unit.

[0044] The two pins of the red and green dual-color LED3 are connected to resistors R25 and R26 respectively. Resistor R25 is connected to GPIO pin 5 of the main control unit, and resistor R26 is connected to GPIO pin 6 of the main control unit.

[0045] The two pins of the red and green dual-color LED4 are connected to resistors R27 and R28 respectively. Resistor R27 is connected to GPIO7 pin of the main control unit, and resistor R28 is connected to GPIO8 pin of the main control unit.

[0046] The two pins of the red and green dual-color LED5 are connected to resistors R29 and R30 respectively. Resistor R29 is connected to GPIO pin 9 of the main control unit, and resistor R30 is connected to GPIO pin 10 of the main control unit.

[0047] Under normal circumstances, the red-green dual-color LED1, LED2, LED3, LED4, and LED5 are all lit up in green. The main control unit determines whether the drilling machine is tilted based on the changes in the angular velocity and linear acceleration of the drilling machine detected by the six-axis gyroscope received by the peripheral circuit. When the drilling machine is tilted, the main control unit controls the red-green dual-color LED1 and the dual-color LED representing the corresponding tilt direction to light up in red through the corresponding GPIO output pin.

[0048] It is worth noting that the red and green dual-color LEDs 2, 3, 4, and 5 are symmetrically distributed around the red and green dual-color LED 1. The red and green dual-color LEDs 2, 3, 4, and 5, representing the tilt direction, are placed around it. That is, the red and green dual-color LED 1 is placed in the middle, and the red and green dual-color LEDs 5, 2, 3, and 4 are placed around it, forming a cross shape. When using the machine, the user can determine whether the drilling machine is tilted by observing the lighting status of the red and green dual-color LEDs 1, thus allowing the operator to quickly determine the tilt direction of the drill hole based on the positional relationship between the lit red dual-color LED and the central red and green dual-color LED 1, ensuring normal drilling operation.

[0049] In summary, during operation, the drilling machine senses the vertical and horizontal positional offset, indicating the offset direction (single or multiple directions) in red. A red light at the center of the indicator flashes simultaneously. After the operator corrects the offset, a green light at the center indicates the standard direction, and the red indicator for the original offset direction turns off. If the machine tilts 10 degrees in any direction relative to the spindle, the light for that direction will illuminate; if it tilts 10 degrees in two directions simultaneously, the lights for both directions will illuminate.

[0050] When the operator deviates from the correct direction during drilling, the direction sensing device on the drilling machine will flash a red light to warn the operator to correct the direction immediately. The direction to be corrected is the opposite of the flashing red light. Once the correction is complete, the red-green LED1 will flash green, indicating that the drilling machine is in the correct direction and can continue drilling. This protects the operator's safety, ensures the accuracy of the drilling operation and the integrity of the hole, and also prevents the drill bit from getting stuck due to drilling deviation, thus improving the safety of drilling machine use.

[0051] Based on the above, it can be seen that this utility model solves the problems that occur during the operation of a drilling machine, when the operator does not hold the drilling machine upright, causing it to deviate from the correct direction to the left, right, or front and back, resulting in skewed drilling results that affect the appearance; the drill bit deviates from the normal position and cannot be drilled through; and the drill bit may get stuck during the drilling process, causing personal safety hazards.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
