[0002] Linear guide pairs are used in high-precision or high-speed linear reciprocating motion applications and can withstand a certain amount of torque, achieving high-precision linear motion under high loads. The positional dimensional accuracy error and parallelism of the slider relative to the linear guide are detected using specialized slider accuracy testing equipment.

[0024] like Figures 1 to 3As shown, a multi-directional detection device for a slider is provided, including an inspection platform 10. A base 1 and a linear guide rail 3 are provided on the inspection platform 10. The linear guide rail 3 is opposite to and parallel to the base 1. The height of the base 1 is greater than the height of the linear guide rail 3. The base 1 has an L-shaped structure including a horizontal part and a vertical part. The horizontal part is horizontally set on the inspection platform 10, and the vertical part is vertically connected to the horizontal part. A square through hole is opened on the side wall of the vertical part. A third platform is provided on the square through hole. A first dial indicator 91 is installed on the third platform. The first dial indicator 91 is parallel to the inspection platform 10 and perpendicular to the vertical part.
[0025] A bracket 2 is provided at the top of the vertical section. One side wall of the bracket 2 is perpendicular to the top surface of the vertical section. The extension direction of the bracket 2 is directly above the linear guide rail 3, and the bracket 2 is parallel to the linear guide rail 3. A slider 4 to be tested is slidably connected to the linear guide rail 3. A first through groove 7 is formed on the top of the slider 4. A first protrusion 71 and a second protrusion 72 are respectively formed on the top of the slider 4 and on both sides of the first through groove 7. A second through groove 8 is formed on the bottom of the slider 4. The slider 4 is slidably connected to the linear guide rail 3 through the second through groove 8. A third protrusion 73 is provided on the top of one side wall of the slider 4. The third protrusion 73 is set along the length of the slider 4, that is, the length of the third protrusion 73 is equal to the length of the slider 4. The third protrusion 73 on one side of the slider 4 is chamfered and connected to the first protrusion 71. The side wall of the vertical section is parallel to the side wall of the slider 4.
[0026] The probe of the first dial indicator 91 passes through the square through hole and contacts the third protrusion 73.

[0027] The second dial indicator 92 is located directly above the first protrusion 71, and the third dial indicator 93 is located directly above the second protrusion 72. When the slider 4 to be tested slides along the linear guide rail 3 through the testing device, the first dial indicator 91 measures the relative positional accuracy error and parallelism of the slider 4 to be tested relative to the side wall of the linear guide rail 3. Here, the third protrusion 73 of the slider 4 to be tested and the side wall of the linear guide rail 3 are located on the same side of the axis of the linear guide rail 3.
[0028] When the slider 4 to be tested slides on the linear guide rail 3 and passes through the testing device, the second dial indicator 92 measures the relative positional accuracy error and the parallelism of the movement between the top surface of the first protrusion 71 and the bottom surface of the linear guide rail 3; when the slider 4 to be tested slides on the linear guide rail 3 and passes through the testing device, the third dial indicator 93 measures the relative positional accuracy error and the parallelism of the movement between the top surface of the second protrusion 72 and the bottom surface of the linear guide rail 3.
[0029] This solution features a simple, compact, and low-cost device. Using a dial indicator and a support, it easily detects the positional dimensional accuracy error and parallelism of the slider relative to the linear guide rail. It is easy to assemble and can be used on a production line, allowing for slider testing directly on the line and improving production efficiency. Furthermore, this device can simultaneously detect the positional dimensional accuracy error and parallelism of the slider relative to the linear guide rail at three points, resulting in high testing efficiency.
