Description

Technical Field

[0001] This utility model relates to the field of parallel bottom light source technology for image measuring instruments, specifically a parallel bottom light source for image measuring instruments. Background Technology

[0002] In the field of modern precision manufacturing and inspection, image measuring instruments have become key equipment for quality control due to their advantages of high precision and non-contact measurement. As a core auxiliary component of image measuring instruments, the performance of parallel bottom light sources directly affects the measurement accuracy and imaging quality. An ideal parallel bottom light source needs to provide uniform, stable and angle-adjustable light to clearly highlight the contours and details of the workpiece.

[0003] When using the parallel bottom light source in existing image measuring instruments,

[0004] (1) The height and angle of the light source are inconvenient to adjust. Traditional parallel bottom light sources are mostly fixed installations, making it difficult to adjust the position and angle of the light source according to the thickness and shape of the workpiece. This results in uneven light illumination and blurred imaging at the edges or complex structures of some workpieces, affecting the accuracy of measurement.

[0005] (2) Poor stability. During long-term measurement, the existing parallel bottom light source is easily affected by external vibration and equipment movement, resulting in positional shift or shaking, which causes unstable light projection. This not only reduces measurement accuracy but also requires frequent calibration, affecting work efficiency.

[0006] To address the above problems, this utility model provides a parallel bottom light source for an image measuring instrument. Utility Model Content

[0007] The purpose of this invention is to provide a parallel bottom light source for an image measuring instrument. This invention achieves flexible adaptation of the light source to different measurement needs through adjustable light source position and angle and stable support structure, ensuring uniform and stable light projection, thereby solving the problems of difficult adjustment and poor stability of traditional parallel bottom light sources.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a parallel bottom light source for an image measuring instrument, comprising a fixed base and an adjustable parallel bottom light source assembly, wherein the adjustable parallel bottom light source assembly is fixedly connected to the top of the fixed base, and the adjustable parallel bottom light source assembly includes a fixed frame fixedly connected to the top of the fixed base;

[0009] A protective column is fixedly connected to the middle of the top of the fixed frame. A hydraulic rod body is fixedly connected inside the protective column. A sliding plate is fixedly connected to the bottom of the hydraulic rod body. A U-shaped frame is fixedly connected to the middle of the front of the sliding plate. A motor box is fixedly connected to one side of the U-shaped frame.

[0010] Furthermore, the sliding plate is slidably connected to the inner wall of the fixed frame, and a servo motor is fixedly connected inside the motor box. A transmission rod is fixedly connected to the output end of the servo motor, so that the servo motor drives the transmission rod to provide power for the position and angle adjustment of the parallel bottom light body, enabling the sliding plate to move precisely within the fixed frame and achieve flexible adjustment of the light source height.

[0011] Furthermore, a protective box is fixedly connected to one end of the transmission rod, and a parallel bottom light body is fixedly connected inside the protective box. This achieves the protective box's function of protecting the parallel bottom light body from external collisions and dust. At the same time, driven by the transmission rod, the light source can be rotated and adjusted at multiple angles to ensure that the light can illuminate the workpiece at a suitable angle.

[0012] Furthermore, fixed plates are fixedly connected to both sides of the front of the sliding plate, and a rotating frame is rotatably connected to the inner wall of the fixed plate. This achieves the purpose of the fixed plate providing installation support for the rotating frame, enabling the rotating frame to rotate flexibly, laying the foundation for subsequent adjustment of the reflector angle, and facilitating the adjustment of light reflection.

[0013] Furthermore, a reflector is fixedly connected to the inner wall of the rotating frame, and an adjustment disc for controlling the angle of the reflector is provided on the surface of the fixed plate. This allows the operator to rotate the adjustment disc to change the angle of the rotating frame and the reflector, thereby reflecting and guiding the light emitted by the parallel bottom light body, filling the blind spots of light illumination, and enhancing the uniformity and utilization of light.

[0014] Furthermore, both sides of the front and back of the fixing base are fixedly connected to stable support components. The stable support components include fixing blocks fixedly connected to the front and back of the fixing base. The fixing blocks are internally threaded with high-strength threaded rods, which can be adjusted by rotating the high-strength threaded rods to adjust their extension length within the fixing blocks. This allows for flexible adjustment of the overall height and level of the parallel bottom light source, enabling it to adapt to different flat surfaces and ensuring stable placement of the light source.

[0015] Furthermore, a control panel is fixedly connected to the top of the high-strength threaded rod, and an anti-slip seat is fixedly connected to the bottom of the high-strength threaded rod. This allows the operator to easily rotate the high-strength threaded rod manually via the control panel, improving the convenience of adjustment. The anti-slip seat increases the friction with the placement surface, preventing the parallel bottom light source from sliding or shifting during use, further enhancing the stability of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a parallel bottom light source for an image measuring instrument.

[0018] (1) By adjusting the settings of the parallel bottom light source assembly, when the personnel operate the device, the height of the sliding plate can be quickly adjusted by the hydraulic rod body according to the thickness and shape of the workpiece. In conjunction with the servo motor driving the transmission rod, the parallel bottom light body is rotated to a suitable irradiation angle. At the same time, the angle of the reflector is changed by adjusting the adjustment plate to make secondary adjustments to the light, ensuring that the light uniformly covers the surface of the workpiece, significantly improving the imaging clarity and measurement accuracy of the image measuring instrument.

[0019] (2) By setting up a stable support component, when the personnel operate the device, they can flexibly adjust the high-strength threaded rod through the control panel according to the actual situation of the placement surface. The anti-slip seat is in close contact with the placement surface, effectively buffering external vibrations. Even during equipment movement or long-term measurement, the parallel bottom light source can be kept stable without displacement, reducing measurement errors and calibration frequency caused by light source shaking, and greatly improving measurement efficiency.

[0026] 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.

[0027] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided:

[0028] A parallel bottom light source for an image measuring instrument includes a fixed base 1 and an adjustable parallel bottom light source assembly 2. The adjustable parallel bottom light source assembly 2 is fixedly connected to the top of the fixed base 1. By adjusting the settings of the parallel bottom light source assembly 2, when the device is used by the operator, the height of the sliding plate 204 can be quickly adjusted according to the thickness and shape of the workpiece using the hydraulic rod body 203. In conjunction with the servo motor 207 driving the transmission rod 208, the parallel bottom light lamp body 210 is rotated to a suitable illumination angle. At the same time, the angle of the reflector 213 is changed by the adjustment plate 214 to perform secondary adjustment of the light, ensuring that the light uniformly covers the surface of the workpiece, significantly improving the imaging clarity and measurement accuracy of the image measuring instrument. The adjustable parallel bottom light source assembly 2 includes a fixed frame 201 fixedly connected to the top of the fixed base 1.

[0029] A protective column 202 is fixedly connected to the middle of the top of the fixed frame 201. A hydraulic rod body 203 is fixedly connected inside the protective column 202. A sliding plate 204 is fixedly connected to the bottom of the hydraulic rod body 203. A U-shaped frame 205 is fixedly connected to the middle of the front of the sliding plate 204. A motor box 206 is fixedly connected to one side of the U-shaped frame 205.

[0030] Specifically, when operating the device, the operator first places the fixed base 1 in the designated position of the image measuring instrument. Based on the thickness of the workpiece being measured, the operator controls the extension and retraction of the hydraulic rod body 203 to drive the sliding plate 204 to slide up and down along the inner wall of the fixed frame 201, thereby adjusting the parallel bottom light body 210 to a suitable height. Subsequently, the horizontality of the device can be finely adjusted through the stable support component 3 to ensure the stability of the light source.

[0031] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0032] The sliding plate 204 is slidably connected to the inner wall of the fixed frame 201. The servo motor 207 is fixedly connected inside the motor box 206. The output end of the servo motor 207 is fixedly connected to the transmission rod 208. The purpose of this design is to use the precise speed and direction control capability of the servo motor 207 to transmit power to the protective box 209 through the transmission rod 208, so as to realize the multi-angle rotation adjustment of the parallel bottom light body 210, so that the light can be projected onto the surface of the workpiece at different angles, which can meet the lighting needs of workpieces with complex shapes.

[0033] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0034] A protective box 209 is fixedly connected to one end of the transmission rod 208. The parallel bottom light body 210 is fixedly connected inside the protective box 209. The purpose of this design is to isolate the protective box 209 from contaminants such as dust and liquids, and to prevent the parallel bottom light body 210 from being damaged by external factors. At the same time, the protective box 209, as the light source carrier, rotates precisely under the drive of the transmission rod 208 to ensure the stability and accuracy of the light projection angle.

[0035] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0036] Fixed plates 211 are fixedly connected to both sides of the front of the sliding plate 204. A rotating frame 212 is rotatably connected to the inner wall of the fixed plate 211. The purpose of this design is to provide a stable rotation fulcrum for the rotating frame 212 through the fixed plate 211, so that the rotating frame 212 can flexibly adjust its angle, providing a structural basis for the subsequent reflector 213 to change the light reflection path, and realizing fine control of the illumination range of the light source.

[0037] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0038] A reflector 213 is fixedly connected to the inner wall of the rotating frame 212. An adjustment disk 214 for controlling the angle of the reflector 213 is provided on the surface of the fixed plate 211. The purpose of this design is that the operator can manually rotate the adjustment disk 214 to drive the rotating frame 212 and the reflector 213 to rotate synchronously. By changing the tilt angle of the reflector 213, the light from the parallel bottom light body 210 is reflected to the shadow area of ​​the workpiece or the area with weak light, eliminating lighting dead angles and improving the uniformity of light.

[0039] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0040] The front and back sides of the fixed base 1 are fixedly connected to the stabilizing support components 3. The stabilizing support components 3 include fixed blocks 301 fixedly connected to the front and back sides of the fixed base 1. The fixed blocks 301 are internally threaded with high-strength threaded rods 302. The purpose of this design is to adjust the horizontal height of the fixed base 1 by rotating the high-strength threaded rods 302 to change their extension length in the fixed blocks 301. Even if there is a slight tilt on the placement surface, the parallel bottom light source can be kept in a horizontal and stable state through the coordinated adjustment of the four sets of high-strength threaded rods 302.

[0041] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0042] A control panel 303 is fixedly connected to the top of the high-strength threaded rod 302, and an anti-slip seat 304 is fixedly connected to the bottom of the high-strength threaded rod 302. The purpose of this design is to increase the contact area of ​​the control panel 303 for rotation operation, so that the operator can quickly and effortlessly adjust the high-strength threaded rod 302. The anti-slip seat 304 increases the friction with the placement surface to prevent the parallel bottom light source from shifting due to vibration or external impact during use, thereby further enhancing the stability of the device.

[0043] Working principle: Before use, the operator adjusts the high-strength threaded rod 302 by rotating the control panel 303, and uses the anti-slip seat 304 to firmly place the fixed seat 1 in the measuring position and calibrate it to a horizontal state. During measurement, according to the workpiece size, the hydraulic rod body 203 is activated to push the sliding plate 204 up and down, adjusting the parallel bottom light body 210 to a suitable height. If the light angle needs to be adjusted, the servo motor 207 is activated, which drives the protective box 209 and the parallel bottom light body 210 to rotate via the transmission rod 208. For areas with insufficient light coverage, the adjustment panel 214 can be manually rotated, and the angle of the reflector 213 can be adjusted through the fixed plate 211 and the rotating frame 212 to reflect light to supplement illumination. Throughout the process, the stable support component 3 continuously buffers external vibrations, ensuring that the parallel bottom light source stably projects uniform light, providing high-quality lighting conditions for the image measuring instrument and ensuring measurement accuracy.
