Description

Technical Field

[0001] This utility model relates to the field of mechanical and electrical technology, specifically a mechanical and electrical adjustment and positioning device. Background Technology

[0002] In the field of mechanical and electrical engineering, whether it is equipment assembly and processing in the production and manufacturing process, or the debugging and maintenance of electrical systems, precise adjustment and positioning are key links to ensure product quality and system performance.

[0003] However, traditional mechanical and electrical adjustment and positioning devices currently have some areas for improvement in practical applications: On the one hand, some devices have limited automation, and many operations require manual operation. For example, moving parts are pushed by manually turning handwheels or adjusting bolts. Operators need to use tools such as rulers and dial indicators to measure distances and calibrate positions. This is not only labor-intensive and inefficient, but also prone to positioning accuracy deviations due to human observation errors and uneven operating force. On the other hand, traditional positioning devices lack effective stabilizing mechanisms after position adjustment. When the equipment is subjected to vibration, external collisions, or other disturbances, the position of moving parts is easily offset, which in turn affects the accuracy of subsequent processing or testing.

[0004] To address these issues, we have provided a mechanical and electrical adjustment and positioning device. Utility Model Content

[0010] The upper end of the movable block is connected to two symmetrically arranged telescopic push rods. The driving ends of the two telescopic push rods face the inner walls of the two sides of the track frame, and the side ends of the telescopic push rods are connected to a controller.

[0011] The telescopic push rod is connected to a pressure sensor at its drive end, and a fixing plate is connected to the side end of the pressure sensor. The surface of the fixing plate is provided with anti-slip grooves.

[0012] A laser rangefinder is connected inside the moving block. The laser head of the laser rangefinder is located at the outer end of the moving block, and it irradiates the inner wall of one end of the track frame with laser light.

[0013] A drive motor is installed on the side of the track frame.

[0014] Furthermore, a numerical control terminal is provided on the side of the drive motor, and a signal transmitter is provided inside the moving block. The signal transmitter is connected to the laser rangefinder and the controller wires respectively.

[0015] Furthermore, the CNC terminal transmits signals to the signal transmitter, and the drive motor is connected to the CNC terminal via wires.

[0016] Furthermore, a roller groove is provided inside the track frame, and a ball bearing is provided inside the moving block, with the ball bearing tumbling within the roller groove of the track frame.

[0017] Furthermore, rectangular grooves are provided at both ends of the track frame, and cleaning heads and cleaning strips are connected to both ends of the moving block.

[0021] (iii) Beneficial effects:

[0022] Compared with existing technologies, this mechanical and electrical adjustment and positioning device has the following advantages:

[0023] I. The mechanical and electrical adjustment and positioning device uses a laser rangefinder to measure the distance between the moving block and the inner wall of one end of the track frame in real time. This data is then fed back to the CNC terminal via a signal transmitter. The CNC terminal controls the drive motor to rotate the lead screw according to the set position parameters, thereby precisely adjusting the position of the moving block and achieving accurate positioning. Simultaneously, the cooperation of the telescopic push rod, pressure sensor, and fixed plate ensures that the moving block is stably fixed in the designated position after it reaches the designated location. The telescopic push rod extends, and the pressure sensor detects the pressure between the fixed plate and the inner wall of the track frame, ensuring the moving block is stably fixed in that position and preventing positional deviation due to external forces. This further guarantees the accuracy and stability of the positioning. The device, through the connection of the CNC terminal, signal transmitter, drive motor, and telescopic push rod controller, achieves automated adjustment and positioning. Operators only need to input parameters such as the target position into the CNC terminal, and the device can automatically complete the movement and fixing of the moving block, reducing manual labor intensity, minimizing errors caused by human factors, and improving the efficiency and consistency of adjustment and positioning.

[0024] Second, the mechanical and electrical adjustment and positioning device, through the setting of the cleaning head and cleaning strip, can automatically clean the impurities in the track frame during the movement of the moving block. When the moving block moves to the sidemost end of the track frame, the impurities can fall through the rectangular groove, thereby ensuring the normal operation of the device, extending the service life of the device, and eliminating the need to stop the machine for complex cleaning operations, thus improving production efficiency.

[0025] Third, the mechanical and electrical adjustment and positioning device is equipped with a magnetic coupler and a shock-absorbing rubber block. The magnetic coupler enables contactless torque transmission, preventing the vibration generated by the motor from being transmitted to the lead screw. The shock-absorbing rubber block reduces the transmission of external vibrations to the track frame. The combination of the two enables the device to operate stably for a long time and improves the overall reliability. Attached Figure Description

[0034] 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.

[0035] like Figures 1-6 As shown, this utility model provides a technical solution: a mechanical and electrical adjustment and positioning device, including a track frame 1, a movable block 2 slidably connected inside the track frame 1, a roller groove opened inside the track frame 1, and a ball bearing 11 disposed inside the movable block 2. The ball bearing 11 is slidably connected inside the roller groove of the track frame 1. The cooperation between the roller groove and the ball bearing 11 reduces the friction force when the movable block 2 slides, making the movement smoother and more stable. A sliding contact line 19 is connected to the side end of the track frame 1, and a current collector 20 is connected to the side end of the movable block 2. The current collector 20 is slidably connected to the outer end of the sliding contact line 19. The two together constitute the power supply system of the movable block 2, ensuring that the movable block 2 can continuously and stably obtain power during the movement process, providing power support for the various electrical components of the device.

[0036] The upper end of the movable block 2 is connected to the mounting plate 3, and the mounting plate 3 has mounting holes. Mechanical and electrical equipment is installed on the mounting plate 3.

[0037] A lead screw 4 is rotatably connected inside the track frame 1. A moving block 2 is threadedly connected to the outer end of the lead screw 4. A drive motor 9 is installed on the side end of the track frame 1. Support covers 15 are connected to both ends of the track frame 1. Bearings 16 are installed inside the support covers 15. Both ends of the lead screw 4 are connected to the bearings 16. The support covers 15 serve to support and protect the bearings 16, preventing external debris from entering and affecting the rotation of the lead screw 4. The bearings 16 provide rotational support for the lead screw 4, reducing the friction when the lead screw 4 rotates, so that the lead screw 4 can rotate smoothly and efficiently.

[0038] The lead screw 4 is connected to the drive end of the drive motor 9 via a magnetic coupler 17. The magnetic coupler 17 enables contactless torque transmission between the drive motor 9 and the lead screw 4, avoiding the direct transmission of vibrations generated by the motor to the lead screw 4 and ensuring the smooth rotation of the lead screw 4. The lower end of the track frame 1 and the lower end of the drive motor 9 are provided with shock-absorbing rubber blocks 18. The lower end of the shock-absorbing rubber blocks 18 is connected to a base plate. The shock-absorbing rubber blocks 18 are used to reduce the interference of external vibrations on the movement of the moving block 2.

[0039] The upper end of the movable block 2 is connected to two symmetrically arranged telescopic push rods 5. The driving ends of the two telescopic push rods 5 face the inner walls on both sides of the track frame 1 respectively. The side ends of the telescopic push rods 5 are connected to a controller, and the driving ends of the telescopic push rods 5 are connected to pressure sensors 6. The side ends of the pressure sensors 6 are connected to a fixing plate 7. The surface of the fixing plate 7 is provided with anti-slip grooves, which increase the friction between the fixing plate 7 and the inner wall of the track frame 1, further ensuring the stability of the positioning. When the movable block 2 reaches the designated position, the telescopic push rods 5 extend under the action of the controller, pushing the fixing plate 7 to contact the inner walls on both sides of the track frame 1. The pressure sensors 6 are used to detect the pressure between the fixing plate 7 and the inner wall of the track frame 1 in real time. When the pressure reaches the set value, it indicates that the movable block 2 has been stably fixed in the position. The pressure sensors 6 feed back the pressure data to the controller, and the controller stops the movement of the telescopic push rods 5.

[0040] A laser rangefinder 8 is connected inside the moving block 2. The laser head of the laser rangefinder 8 is located at the outer end of the moving block 2. It irradiates the inner wall of one end of the track frame 1 with laser light. The laser rangefinder 8 uses the principle of laser reflection to measure the distance between the moving block 2 and the inner wall of one end of the track frame 1 in real time. Laser ranging has the characteristics of high precision and high speed, and can quickly and accurately obtain the position information of the moving block 2.

[0041] A CNC terminal 10 is installed on the side of the drive motor 9, and a signal transmitter is installed inside the moving block 2. The signal transmitter is connected to the laser rangefinder 8 and the controller wires respectively. The CNC terminal 10 transmits signals to the signal transmitter, and the drive motor 9 is connected to the CNC terminal 10 wires. The data measured by the laser rangefinder 8 is transmitted to the CNC terminal 10 through the signal transmitter. The signal transmitter is not only responsible for the data transmission between the laser rangefinder 8 and the CNC terminal 10, but also connected to the controller wires of the telescopic push rod 5 to realize the signal interaction between the components and ensure that the device can perform precise automatic adjustment and positioning according to the actual position information.

[0042] The track frame 1 has rectangular grooves 12 at both ends. The moving block 2 is connected to cleaning heads 13 and cleaning strips 14 at both ends. The cleaning heads 13 are slidably connected in the roller groove of the track frame 1, and the cleaning strips 14 are slidably connected to the bottom plate of the track frame 1. Both of them move together with the moving block 2, which can clean dust, debris and other impurities in the track frame 1 in a timely manner. When the moving block 2 moves to the side of the track frame 1, the impurities can fall through the rectangular grooves 12, thereby keeping the inside of the track frame 1 clean.

[0043] Working principle: When in use, the operator first inputs the target position parameters to be adjusted on the CNC terminal 10. The CNC terminal 10 sends the control signal to the drive motor 9. The drive motor 9 drives the lead screw 4 to rotate through the magnetic coupler 17. The rotation of the lead screw 4 causes the moving block 2, which is threaded to its outer end, to move along the track frame 1.

[0044] The laser rangefinder 8 inside the moving block 2 measures the distance between the moving block 2 and the inner wall of one end of the track frame 1 in real time, and feeds the data back to the CNC terminal 10 through the signal transmitter. The CNC terminal 10 compares the received distance information with the set target position and adjusts the rotation of the drive motor 9 in real time. When the moving block 2 approaches the target position, the speed of the drive motor 9 is gradually reduced to achieve precise positioning.

[0045] When the moving block 2 reaches the target position, the CNC terminal 10 sends a command to the controller of the telescopic push rod 5. The controller controls the telescopic push rod 5 to extend, so that the fixed plate 7 contacts the inner walls on both sides of the track frame 1. The pressure sensor 6 detects the pressure between the fixed plate 7 and the inner wall of the track frame 1 in real time and feeds the pressure data back to the controller. When the pressure reaches the set value, the controller stops the movement of the telescopic push rod 5. At this time, the moving block 2 is stably fixed in the target position, effectively preventing the position from shifting due to external force. In this way, the device completes the automatic adjustment and positioning operation.
