Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a lamp post quality calibration device. Background Technology
[0002] As a core supporting component in road lighting, surveillance installation, and other scenarios, the straightness, coaxiality, and other geometric tolerances of light poles directly affect installation stability and service life. Currently, in the production process of light poles, quality calibration mainly relies on manual operation: using a string method to check straightness, employing a level for positioning, or manually rotating the light pole segment by segment to measure deviations. The aforementioned traditional calibration methods have significant drawbacks: First, they have low detection accuracy and large errors due to manual observation, making it difficult to meet the quality requirements of high-precision light poles (such as those used in municipal engineering); second, they have low operational efficiency, cannot be adapted to mass production scenarios, and involve high labor intensity; third, they have poor versatility, requiring the replacement of special tooling with light poles of different diameters and lengths, resulting in insufficient universality; and finally, they lack quantitative data, with calibration results relying on the operator's experience and unable to generate standardized test reports. Therefore, there is an urgent need for a light pole quality calibration device with a high degree of automation, high detection accuracy, and strong adaptability to solve the above-mentioned problems in the existing technology. Utility Model Content
[0003] The purpose of this invention is to provide a light pole quality calibration device with reasonable structure, convenient operation, high detection accuracy, and strong adaptability, so as to realize the automatic calibration of the straightness and coaxiality of the light pole, and improve the detection efficiency and standardization.
[0004] To achieve the aforementioned objectives, this utility model provides a light pole quality calibration device, employing the following technical solution: A light pole quality calibration device, comprising: The mounting frame serves as the load-bearing foundation for the device. It is made of high-strength aluminum alloy profiles welded together and has an overall rectangular frame structure. The slide rails are installed above the mounting frame. There are two slide rails, which are arranged horizontally and parallel to each other along the length of the mounting frame. A gap is left between the two slide rails to accommodate the calibration of the light pole. The slide rails are high-precision linear slide rails and are fixedly connected to the top end face of the frame by bolts. Two calibration seats are slidably installed between two slide rails. The two calibration seats are arranged at intervals along the length of the slide rails. The bottom of the calibration seat is fixed to the slider of the slide rail by bolts. It can slide back and forth along the length of the slide rail. The two calibration seats are arranged at intervals along the length of the slide rails. The spacing can be adjusted according to the length of the lamp post to be calibrated. The calibration base is fixedly equipped with a mounting base for placing the lamp post. The center of the mounting base has an arc-shaped groove for the lamp post to pass through. Several rollers for supporting the lamp post and assisting the lamp post to rotate are rotatably installed at the bottom of the groove. A laser emitter is fixedly installed on one side of the groove, and a laser receiver is fixedly installed on the other side of the groove corresponding to the position of the laser emitter. The laser receiver is electrically connected to an external controller. It also includes a drive mechanism for driving the two calibration seats to slide synchronously or independently along the slide rail. The drive mechanism is fixedly connected to the mounting frame and engages with the calibration seats in a transmission manner. By adjusting the spacing between the calibration seats through a servo motor, combined with laser detection and controller data processing, manual intervention is reduced and detection efficiency is improved.
[0005] A further improvement of the lamp post quality calibration device of this utility model is that the driving mechanism includes a bidirectional lead screw, a drive motor and a nut seat. The bidirectional lead screw is horizontally mounted between two slide rails and is rotatably connected to the mounting frame. There are two nut seats, which are respectively screwed to the threaded sections at both ends of the bidirectional lead screw. The two nut seats are respectively fixedly connected to the corresponding calibration seats. The drive motor is fixed to the end of the mounting frame and the output shaft is coaxially fixedly connected to the bidirectional lead screw.
[0006] A further improvement of this utility model of a light pole quality calibration device is that the rollers are made of rubber, and several rollers are evenly arranged along the length of the groove. The axis of the rollers is perpendicular to the length of the slide rail. The rollers support the weight of the light pole and assist the light pole in rotating around its own axis to achieve full circumferential calibration.
[0007] A further improvement of this utility model of a lamp post quality calibration device is that the mounting base and the calibration base are detachably connected, and a flexible protective pad is detachably attached to the inner wall of the arc-shaped groove of the mounting base, and the surface of the flexible protective pad is provided with anti-slip texture.
[0008] A further improvement of the lamp post quality calibration device of this utility model is that there are several groups of laser emitters and laser receivers, with several groups of laser emitters arranged at intervals along the height direction of the groove, and several groups of laser receivers corresponding to and adapted to the laser emitters one by one.
[0009] A further improvement of this utility model of a light pole quality calibration device is that a number of leveling feet are fixedly provided at the bottom of the mounting frame. The leveling feet are evenly distributed along the four corners of the bottom of the mounting frame, and the height of the leveling feet is adjustable.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The laser inspection component is far superior to traditional string line and level inspection methods, meeting the quality requirements of high-precision light poles. By adjusting the calibration seat spacing through a servo motor, combined with laser detection and controller data processing, manual intervention is reduced and detection efficiency is improved. The mounting base is removable and replaceable, and the flexible protective pad can be adapted to light poles of different diameters, eliminating the need to replace the entire set of tooling and reducing production costs; The flexible protective pads and rubber rollers inside the arc-shaped grooves prevent scratches on the surface of the light pole and enhance the smoothness of the light pole's rotation.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] The components include a mounting frame 1, a slide rail 2, a calibration seat 3, a mounting base 31, and rollers 32. Detailed Implementation
[0013] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0014] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0015] In the description of this utility model, it should be noted that the terms "vertical," "outer peripheral surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0016] Furthermore, terms such as "vertical" do not imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. Similarly, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0017] like Figure 1 As shown, a light pole quality calibration device includes: Mounting frame 1, which serves as the load-bearing foundation of the device, is made of high-strength aluminum alloy profiles welded together, and has an overall rectangular frame structure. The slide rail 2 is installed above the mounting frame. There are two slide rails, which are arranged horizontally and parallel to each other along the length of the mounting frame. A gap is left between the two slide rails to accommodate the calibration of the light pole. The slide rails are high-precision linear slide rails and are fixedly connected to the top end face of the frame by bolts. The calibration seat 3 is slidably installed between the two slide rails. There are two calibration seats, and the two calibration seats are arranged at intervals along the length of the slide rails. A mounting base 31 for placing a light pole is fixedly installed on the calibration base. An arc-shaped groove is formed in the center of the mounting base for the light pole to pass through. Several rollers 32 are rotatably mounted at the bottom of the groove to support the light pole and assist its rotation. A laser emitter is fixedly installed on one side of the groove, and a laser receiver is fixedly installed on the other side of the groove corresponding to the laser emitter. The laser receiver is electrically connected to an external controller. The laser detection assembly includes several sets (preferably 3 sets) of laser emitters and laser receivers, spaced apart along the height of the groove (80-120mm spacing). The laser emitter is fixed to one side of the groove by a bracket, and the laser receiver is correspondingly fixed to the other side of the groove, with each receiver corresponding to and adapted to the laser emitter (the axes of the emitting and receiving ends coincide). The laser emitter uses a semiconductor laser source (wavelength 650nm, power 5mW, spot diameter ≤2mm), and the laser receiver uses a photodiode receiver (response time ≤1μs, detection accuracy ±0.01mm). The laser receiver is electrically connected to an external controller (such as a PLC controller, model S7-200SMART), which can convert laser blocking or offset signals into electrical signals and transmit them to the controller. It also includes a drive mechanism for driving the two calibration seats to slide synchronously or independently along the slide rail. The drive mechanism is fixedly connected to the mounting frame and engages with the calibration seats in a transmission manner. By adjusting the spacing between the calibration seats through a servo motor, combined with laser detection and controller data processing, manual intervention is reduced and detection efficiency is improved.
[0018] Specifically, the drive mechanism includes a bidirectional lead screw, a drive motor, and nut seats. The bidirectional lead screw is horizontally mounted between two slide rails and is rotatably connected to the mounting frame. There are two nut seats, which are screwed onto the threaded sections at both ends of the bidirectional lead screw. The two nut seats are fixedly connected to the corresponding calibration seats. The drive motor is fixed to the end of the mounting frame, and its output shaft is coaxially fixedly connected to the bidirectional lead screw.
[0019] Specifically, the rollers are made of rubber, and several rollers are evenly distributed along the length of the groove, with the axis of the rollers perpendicular to the length of the slide rail.
[0020] Specifically, the mounting base and the calibration base are detachably connected. The inner wall of the arc-shaped groove of the mounting base is detachably fitted with a flexible protective pad, and the surface of the flexible protective pad is provided with anti-slip texture.
[0021] Specifically, there are several sets of laser emitters and laser receivers. The sets of laser emitters are arranged at intervals along the height of the groove, and the sets of laser receivers are matched one-to-one with the laser emitters.
[0022] Specifically, the bottom of the mounting frame is fixed with several leveling feet, which are evenly distributed along the four corners of the bottom of the mounting frame, and the height of the leveling feet is adjustable.
[0023] The specific working principle of this utility model is as follows: The municipal road light pole is passed through the arc-shaped grooves of the two mounting brackets, with each end of the pole extending 50mm beyond the calibration bracket. The calibration bracket spacing is set to 2.9m via the touchscreen. The drive motor is started, and the calibration bracket automatically moves to the set position and is positioned. The laser detection function is activated, and the light pole is manually rotated. The controller displays the deviation data of each section of the light pole in real time. After calibration, the touchscreen displays a maximum deviation value of 0.3mm (less than the preset threshold of 0.5mm), indicating that the light pole is qualified. If the deviation value exceeds the standard, the operator corrects the light pole according to the displayed deviation position and recalibrates until it is qualified.
[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
