The track of the standard linear guide 2 can be fixedly installed on the horizontal surface 1. The horizontal surface 1 is also provided with a hole for fixing and installing a linear guide 7 to be detected. The track of the linear guide 7 to be detected is arranged parallel and spaced from the track of the standard linear guide 2. The load-bearing platform 3 is fixedly installed on the slider of the standard linear guide 2. The drive device 5 drives the load-bearing platform 3 to reciprocate in a straight line. The load-bearing platform 3 is provided with a compensation slider 8 that can slide along the extension direction of the track of the vertical standard linear guide 2. A position sensing device 9 is fixedly installed on the compensation slider 8. The compensation slider 8 can be fixedly connected to the slider of the linear guide 7 to be detected, and at least three position sensors 4 are fixedly installed on the horizontal platform 1 at intervals along the track extension direction of the linear guide. When the position sensing device 9 on the load platform 3 passes through each position sensor 4, each position sensor 4 can respectively detect the distance between it and the position sensing device 9 along the track extension direction perpendicular to the standard linear guide 2. Each position sensor 4 is electrically connected and communicated with the control system. The control system can analyze and calculate the parallelism of the linear guide 7 to be detected and the standard linear guide 2 and output the detection data through the detection result output device 6. The control system can also control the operation of the driving device 5. The operating switch is electrically connected to the control system, and the operating switch can control the operation of the system.

[0021] During detection, the linear guide to be detected is fixedly installed on the horizontal platform 1. After installation, the linear guide to be detected is arranged in parallel with the standard linear guide 2. The system is started by operating the switch. The driving device 5 drives the load platform 3 to reciprocate linearly along the track extension direction of the standard linear guide 2, thereby driving the position sensing device 9 to reciprocate linearly along the track extension direction of the linear guide 7 to be detected. When the position sensing device 9 passes through each position sensor 4, each position sensor 4 automatically measures the distance between the two along the extension direction perpendicular to the standard linear guide 2, and transmits the measurement data to the control system. After multiple position sensors 4 measure and transmit the distance between the position sensing device 9 and the position sensor 4 at different positions, the control system will automatically calculate the parallelism data of the linear guide 7 to be detected and the standard linear guide 2, and finally obtain the straightness data of the linear guide 7 to be detected. The equipment has a simple structure, accurate measurement, high measurement efficiency, can be used in any occasion, can be operated without professional personnel, and can clearly and directly show the straightness of the linear guide to customers.

[0022] There are at least two standard linear guide rails 2, which are arranged in parallel and spaced apart. Multiple standard linear guide rails 2 can enhance the guiding accuracy and reduce the measurement error.

[0023] The position sensors 4 are photoelectric sensors, and each photoelectric sensor is located on the same straight line parallel to the linear guide rail.

[0024] The horizontal platform surface 1 is also fixed with a first limit block 10 and a second limit block 11, which are respectively located at the two ends of the track length direction of the standard linear guide 2, and the two side walls of the load-carrying platform 3 are respectively stopped on the side walls opposite to the first limit block 10 and the second limit block 11. The first limit block 10 and the second limit block 11 limit the sliding range of the load-carrying platform 3 to prevent it from detaching from the track of the standard linear guide 2.

[0025] The first limit block 10 and the second limit block 11 are also provided with contact sensors, and the contact sensors are electrically connected and communicated with the control system.

[0026] The contact sensor sends a signal that the designated position has been reached to the control system, and the control system controls the driving device 5 to drive in the reverse direction, thereby achieving automatic reciprocating sliding of the load-carrying platform 3 .

[0027] The driving device 5 is a linear motor, the magnetic track 21 of the linear motor is fixedly mounted on the horizontal platform 1, and the magnetic track 21 of the linear motor is arranged parallel and spaced with the track of the standard linear guide 2, and the mover 22 of the linear motor is fixedly connected to the load platform 3. In addition, it can also be a rotating motor driving a screw nut mechanism, which is an equivalent replacement structure that can be easily thought of by those skilled in the art based on this patent and falls within the protection scope of this patent.

[0028] A counter is also provided, which can count the number of reciprocating motions of the load-carrying platform 3, and the counter is electrically connected and communicated with the control system, so as to enable the control system to calculate the number of linear reciprocating motions of the load-carrying platform 3, and automatically realize analysis, calculation and shutdown.

The control system is located inside the box body 12, and the horizontal surface 1 is fixedly installed on the horizontal surface 13 at the upper end of the box body 12. The detection result output device 6 and the operation switch are located on the inclined surface 14 at the upper end of the box body 12. Installing the horizontal surface 1 on the horizontal surface 13 of the box body 12 can ensure the accuracy of the measurement data, and arranging the detection result output device 6 and the operation switch on the inclined surface 14 of the box body 12 facilitates the observation and operation of the detection results.

[0030] The lower end of the box 12 is also provided with at least three universal wheels 15 and at least three feet 16. The feet 16 are installed at the lower end of the box 12 with adjustable height. The feet 16 are provided with a positioning device for connecting the feet 16 with the box 12 for fixed positioning. By retracting the feet 16, the universal wheels 15 are grounded, which is convenient for carrying the equipment. When the position is determined, the feet 16 are extended so that the feet 16 support the box 12, which can ensure that the box 12 is stably positioned on the ground, and the levelness of the horizontal plane 13 can also be adjusted. The height adjustment of the feet 16 can be achieved by a screw and nut matching structure, or by a pull-out structure matching a tapered sleeve clamping mechanism.
