[0020] The utility model provides a kind of rolling linear guide precision detection device as shown in the accompanying Figures 1-3 As shown in the accompanying drawings, a rolling linear guide precision detection device is provided, which comprises a detection platform 1, a driving motor 2 is fixedly connected to the detection platform 1, a lead screw 3 is provided at the output end of the driving motor 2, a movable seat 4 is threadedly connected to the lead screw 3, a fixed block 5 is provided above the movable seat 4, the fixed block 5 and the movable seat 4 are fixedly connected through a connecting column 14, a ⊥-shaped side plate 6 is installed on one side of the detection platform 1, the ⊥-shaped side plate 6 is provided with a guide rail 7 to be detected on the side close to the lead screw 3, the guide rail 7 to be detected is installed on the side of the ⊥-shaped side plate 6, a detection slider 8 is slidably connected to the guide rail 7 to be detected, a right-angle bending rod 9 is fixedly connected to the detection slider 8 on one side and penetrates through the fixed block 5, and a drawing pen 10 is fixedly connected to the bottom of the right-angle bending rod 9.
[0021] As shown in the accompanying drawings, Figure 1 and Figure 2 In the utility model, the ⊥-shaped side plate 6 is fixedly installed on the detection platform 1 through a plurality of bolts, and a groove is provided on the side of the ⊥-shaped side plate 6 for installing the guide rail 7 to be detected, so as to adjust the installation position according to the specific specifications of the guide rail 7 to be detected, and ensure the stability and accuracy of the detection process.
[0022] As shown in the accompanying drawings, Figures 1-3 In the utility model, a guide rod 11 is fixedly connected to the detection platform 1 on both sides of the lead screw 3, and both guide rods 11 penetrate through the movable seat 4, so as to accurately limit the moving direction of the movable seat 4, avoid the deviation or shaking of the movable seat 4 during the transmission process of the lead screw 3, further improve the detection accuracy, and improve the stability of the lead screw 3 during rotation by providing a bearing seat 12 installed on the detection platform 1 at the end of the lead screw 3 away from the driving motor 2.
[0023] AsFigure 1 and Figure 2 As shown, in this utility model, the detection platform 1 is provided with a paper loading slot located below the drawing pen 10, and the bottom end of the drawing pen 10 is in contact with the paper loading slot, so that the drawing pen 10 can accurately draw the precision deviation trajectory of the guide rail on the paper during the movement.
[0024] like Figures 1-3 As shown, in this utility model, the detection slider 8 and the fixed block 5 are connected by a spring 13 sleeved on the outside of the right-angle bent rod 9, which makes the sliding of the detection slider 8 on the guide rail 7 under test more stable and tighter. Even if there are slight surface unevenness of the guide rail 7 under test, the spring 13 can provide a certain elastic compensation to ensure good contact between the detection slider 8 and the guide rail 7 under test, thereby reducing the detection error caused by poor contact.
[0025] Working principle: In the specific implementation of this utility model, the guide rail 7 to be inspected is installed in the groove of the ⊥-shaped side plate 6 and adjusted to an appropriate position. The drive motor 2 is started, and the output end of the drive motor 2 drives the lead screw 3 to rotate. Since the movable seat 4 is threadedly connected to the lead screw 3, the movable seat 4 will move along the axial direction of the lead screw 3. At the same time, the guide rod 11 precisely limits the movement direction of the movable seat 4 to ensure that the movable seat 4 moves smoothly. The fixing block 5 above the movable seat 4 moves together with the movable seat 4. The fixing block 5 is fixedly connected to the movable seat 4 through the connecting column 14 to ensure the stability of the structure.
[0026] The detection slider 8 slides on the guide rail 7 to be inspected. Since the detection slider 8 and the fixed block 5 are connected by a spring 13, the spring 13 provides a certain elastic force, so that the detection slider 8 is in close contact with the guide rail 7 to be inspected. When the movable seat 4 moves, the detection slider 8 slides on the guide rail 7 to be inspected, and drives the drawing pen 10 to draw the accuracy deviation trajectory of the guide rail on the paper in the paper slot through the right angle bent rod 9.
[0027] By observing the trajectory drawn by the drawing pen 10, the accuracy deviation of the guide rail 7 under inspection can be intuitively understood, providing a reliable basis for subsequent accuracy adjustment. The entire inspection process is highly efficient and automated, significantly improving inspection efficiency and data continuity, while reducing the impact of human error.
