[0003] However, some existing 3D laser contour sensors do not have cable anti-loosening mechanisms. During long-term use, this may not only damage the cable but also affect the sensor's detection results.

[0004] Therefore, those skilled in the art have provided a 3D laser profile sensor with a cable anti-loosening mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a 3D laser profile sensor with a cable anti-loosening mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A 3D laser contour sensor with a cable anti-loosening mechanism includes a contour sensor housing; the upper and lower ends of the right side of the contour sensor housing are fixedly connected to side connection points, the side connection points are provided with connecting cables inside, and the front and rear sides of the side connection points are provided with support crossbars. The right side of the support crossbars has a slot with a first threaded hole, the first threaded hole is threaded with a side fixing bolt, one side of the side fixing bolt is fixedly connected to a side rotating handle, the other side of the side fixing bolt is fixedly connected to a clamping plate, and one side of the clamping plate is fixedly connected to a protective pad.

[0007] As a further embodiment of this utility model, the upper ends of the front and rear sides of the outer surface of the contour sensor housing are grooved with damping grooves, and several mounting blocks are slidably connected inside the damping grooves.

[0008] As a further embodiment of this utility model, the mounting block has a second threaded hole in its internal slot, and an upper fixing bolt is connected to the internal thread of the second threaded hole.

[0009] As a further embodiment of this utility model, an upper rotating handle is fixedly connected to the lower side of the upper fixing bolt.

[0010] As a further embodiment of this utility model, the outer surface of the contour sensor housing has several heat dissipation grooves on the front and rear sides, and a filter screen is fixedly connected inside the heat dissipation grooves.

[0011] As a further embodiment of this utility model, a laser lens is fixedly connected to the lower left end of the contour sensor housing, and an objective lens is fixedly connected to the lower right end of the contour sensor housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The connecting cable can be secured and fixed using clamps and protective pads. During the operation of the contour sensor housing, the connecting cable is responsible for transmitting electrical signals related to laser emission, reception, and signal processing. If the connecting cable becomes loose, poor contact may occur at the connection point, leading to momentary interruption or signal distortion, affecting the accuracy and integrity of the measurement data. Clamps and protective pads firmly fix the connecting cable, ensuring it remains in a stable connection state. This allows the contour sensor housing to continuously and stably transmit the measured object contour information accurately to external devices. Contour sensor housings are commonly used in measurement scenarios with high precision requirements, such as precision inspection of industrial parts and model data acquisition in reverse engineering. Even minute signal fluctuations can lead to significant deviations in the final measurement results. The clamps and protective pads prevent loosening of the connecting cables, avoiding errors caused by signal transmission problems. This helps maintain the high-precision measurement performance of the contour sensor housing, meeting the stringent requirements of applications demanding high measurement accuracy. When the connecting cables are loose, they rub and pull against surrounding objects during equipment operation, vibration, or daily movement, easily damaging the cable sheath and potentially causing internal wire breakage. The clamps and protective pads limit unnecessary movement of the connecting cables, reducing friction and pulling with the surrounding environment, maximizing the protection of the cable's physical integrity, thus extending its normal service life and reducing the cost and frequency of replacement due to frequent cable damage. Furthermore, loose connecting cables cause repeated stress at the side connections, accelerating wear on the metal contacts, affecting conductivity, and potentially leading to premature failure of the side connections. The clamps and protective pads keep the connecting cables stable and evenly stressed at the connection points, reducing the burden on the side connections, slowing down the wear rate at the connection points, and ensuring a long-term reliable electrical connection between the connecting cables, the contour sensor housing, and other related equipment.

[0013] 2. The horizontal position of the contour sensor housing can be adjusted by moving the mounting block. Different installation environments and equipment layouts have varying requirements for the installation position of the housing. The adjustable mounting block allows the housing to better adapt to various complex installation scenarios, facilitating precise installation by installers based on actual conditions. This reduces installation difficulties caused by space limitations, improves installation efficiency and quality, and allows the housing to better adapt to external mounting brackets of different sizes, further enhancing its applicability. Precise adjustment of the mounting block's horizontal position also ensures an ideal relative position between the housing and the object being measured. This ensures the laser beam is projected onto the object's surface at the optimal angle, and the reflected light is received along the optimal path, thereby improving measurement accuracy and reliability.

Detailed Implementation

[0019] Please see Figures 1-4 In this embodiment of the present invention, a 3D laser contour sensor with a cable anti-loosening mechanism includes a contour sensor housing 1; the upper and lower ends of the right side of the contour sensor housing 1 are fixedly connected to side connection points 2, the inside of the side connection points 2 is provided with a connecting cable 3, and the front and rear sides of the side connection points 2 are provided with support crossbars 4, the right side of the support crossbars 4 has a slotted first threaded hole 5, the inside of the first threaded hole 5 is threaded with a side fixing bolt 6, one side of the side fixing bolt 6 is fixedly connected to a side rotating handle 7, the other side of the side fixing bolt 6 is fixedly connected to a clamping plate 8, and one side of the clamping plate 8 is fixedly connected to a protective pad 9; the contour sensor housing 1 The outer surface of the contour sensor housing 1 has grooves on the upper ends of the front and rear sides, with damping grooves 10 and several mounting blocks 11 slidably connected inside the damping grooves 10; the mounting blocks 11 have grooves with second threaded holes 12 inside, and upper fixing bolts 13 are threaded inside the second threaded holes 12; an upper rotating handle 14 is fixedly connected to the lower side of the upper fixing bolts 13; the outer surface of the contour sensor housing 1 has grooves on the front and rear sides, with several heat dissipation grooves 15 inside, and filters 16 are fixedly connected inside the heat dissipation grooves 15; a laser lens 17 is fixedly connected to the lower left end of the contour sensor housing 1, and an objective lens 18 is fixedly connected to the lower right end of the contour sensor housing 1.

[0020] The working principle of this utility model is as follows: When the contour sensor housing 1 needs to be used, it can be fixedly connected to the external mounting bracket by the upper fixing bolt 13. When the horizontal position of the mounting block 11 needs to be adjusted, the mounting block 11 can be moved horizontally along the damping groove 10. After moving to the appropriate position, the movement is stopped, and the mounting block 11 is fixed in this position. At this time, the horizontal position of the mounting block 11 is adjusted. The horizontal position can be adjusted by moving the mounting block 11. Different installation environments and equipment layouts have different requirements for the installation position of the contour sensor housing 1. The adjustable horizontal position of the mounting block 11 allows the contour sensor housing 1 to better adapt to various complex installation scenarios, making it convenient for installers to perform precise installation according to the actual situation, reducing installation difficulties caused by installation space limitations, improving installation efficiency and quality, and also allowing the contour sensor housing 1 to better adapt to external mounting brackets of different sizes, further improving the applicability of the contour sensor housing 1. Furthermore, the precise adjustment of the horizontal position of the mounting block 11 can also maintain an ideal relative positional relationship between the contour sensor housing 1 and the measured object. This ensures that the laser beam is projected onto the surface of the object being measured at the optimal angle, and that the reflected light is received along the optimal path, thereby improving the accuracy and reliability of the measurement. Then, the connecting cable 3 is inserted into the corresponding side connection 2, and the side fixing bolt 6 is rotated by the side rotating handle 7. The side fixing bolt 6 will then drive the clamp 8 and the protective pad 9 to move to one side of the connecting cable 3 until the protective pad 9 is in complete contact with the connecting cable 3. At this point, the connecting cable 3 is fixed in place, thus preventing it from becoming loose during subsequent use. The clamp 8 and the protective pad 9 can be used to fix the connecting cable 3 in place. During the operation of the contour sensor housing 1, the connecting cable 3 is responsible for transmitting electrical signals related to laser emission, reception, and signal processing. If the connecting cable 3 becomes loose, poor contact may occur at the connection point, causing a momentary interruption of signal transmission or signal distortion, affecting the accuracy and integrity of the measurement data. The clamp 8 and protective pad 9 firmly secure the connecting cable 3, ensuring a stable connection. This allows the contour sensor housing 1 to continuously and stably transmit the measured object contour information accurately to external devices. The contour sensor housing 1 is commonly used in measurement scenarios requiring high precision, such as precision inspection of industrial parts and model data acquisition in reverse engineering. Even minute signal fluctuations can lead to significant deviations in the final measurement results.The clamp 8 and protective pad 9 prevent the connecting cable 3 from becoming loose, avoiding errors caused by signal transmission problems. This helps maintain the high-precision measurement performance of the contour sensor housing 1, meeting the stringent requirements of applications demanding high measurement accuracy. Furthermore, when the connecting cable 3 is loose, it will rub and pull against surrounding objects during equipment operation, vibration, or daily movement, easily causing damage to the outer sheath and internal wires. The clamp 8 and protective pad 9 limit unnecessary movement of the connecting cable 3, reducing friction and pulling with the surrounding environment, maximizing the protection of the physical integrity of the connecting cable 3, thereby extending its normal service life and reducing the cost and frequency of replacement due to frequent damage. In addition, a loose connecting cable 3 will cause repeated stress on the side connection 2, leading to accelerated wear of the metal contacts within the side connection 2, affecting its conductivity, and potentially causing premature failure of the side connection 2. The clamp 8 and protective pad 9 allow the connecting cable 3 to remain stable and evenly stressed at the connection point, reducing the burden on the side connection 2, slowing down the wear rate at the connection point, and ensuring a long-term reliable electrical connection between the connecting cable 3 and the contour sensor housing 1 and other related equipment.
