[0037] Reference Figures 1 to 11 A double-mast skid precision testing device includes a base frame 1, a main slide rail 2, a side slide rail 3, an X-direction fixing part 4, a Y-direction fixing part 5, an X-direction positioning part 6, a Y-direction positioning part 7, a flatness testing part 8, a mast testing part 9, and a step 10.

[0038] Reference Figures 1 to 4 The base frame 1 has main slides 2 symmetrically arranged on both sides for the skids 12 to enter and exit. Side slides 3 are arranged adjacent to the outside of the main slides 2 to guide the skids 12 to enter and exit. Multiple side slides 3 are arranged at intervals on each side. The main slides 2 use 6205ZZ bearings. There are two rows of bearings on each side of the main slides 2. The bearing shaft spacing is 80mm, the bearing diameter is 52mm, and the bearing spacing is 28mm. The side slides 3 have a single row of bearings with the same spacing as the main slides 2.

[0039] Reference Figures 4 to 6The base frame 1 is also provided with an X-direction fixing part 4 and a Y-direction fixing part 5 for fixing the skid 12, and an X-direction positioning part 6 and a Y-direction positioning part 7 for positioning the skid 12. Both the X-direction fixing part 4 and the Y-direction fixing part 5 include quick clamps 11 for pressing the skid. To meet the needs of inspecting skids of various specifications, the X-direction fixing parts 4 can also be added in pairs to accommodate shorter skids. The X-direction positioning part 6 is arranged opposite to the X-direction fixing part 4 to effectively stabilize the skid in the X direction. The Y-direction positioning part 7 is arranged opposite to the Y-direction fixing part 5 to effectively stabilize the skid in the Y direction. The X-direction positioning part 6 is located on both rear sides of the base frame 1, with front and rear sections on each side. Two X-axis positioning parts 6, one in front and one in back, are used to limit the movement of different sized skids after they enter. The X-axis positioning parts 6 are detachable and can be installed and limited according to the specifications of the skids. The Y-axis positioning part 7 includes a positioning base 701, a slide rail fixing seat 702 set on the positioning base 701, a movable positioning slide rail 703 set in the slide rail fixing seat 702, and a positioning pin 704 that can fix the positioning slide rail 703 through the slide rail fixing seat 702. The positioning pin 704 can be inserted into the positioning hole set on the positioning slide rail 703. The X-axis fixing part 4, the Y-axis fixing part 5, and the Y-axis positioning part 7 remain open when the skid 12 moves in and out.

[0040] Reference Figure 4 , Figure 10 , Figure 11 The base frame 1 has symmetrically arranged flatness detection units 8 on both sides. The flatness detection units 8 are used to detect the flatness of the skid 12. Each side has at least 3 flatness detection units 8. In this embodiment, each side has 4 flatness detection units 8. The flatness detection unit 8 includes an arc-shaped base 801. A detection rod 802 is provided through one end of the arc-shaped base 801. A bushing 806 is provided on the detection rod 802. The detection rod 802 can move up and down. A return spring 803 is sleeved on the detection rod 802. A scale line 8021 is provided, with lines engraved around the entire circumference of the detection rod 802 at 1mm intervals. The center 0 line is red, and the other lines are black. Preferably, there are 5 lines above and below the 0 line to represent positive and negative. When not in the detection state, the detection rod 802 is raised to a distance of about 15mm from the skid. During detection, the ball handle 804 of the detection rod 802 is pressed to push one end of the detection rod 802 onto the skid. The specific detection value is read through the indicator mark on the cover plate 805 of the arc-shaped base 801 and the scale line 8021.

[0041] Reference Figure 7 , Figure 8The base frame 1 has main columns 101 on both sides, and crossbars 102 on the main columns 101. Each crossbar 102 has a mast detection section 9 for detecting the accuracy of the mast 13. To enhance the stability of the main columns 101, reinforcing ribs are also provided, with one end fixed to the base frame 1 and the other end fixed to the main columns 101. In this embodiment, there are three crossbars 102, each with two mast detection sections 9, for a total of six mast detection sections 9, forming two rows of mast detection sections 9. Based on the principle of three points determining a straight line, the accuracy of the mast 13 is detected through the three mast detection sections 9 in each row. The mast detection unit 9 includes a detection base 901, a slide rail 902 mounted on the detection base 901, a detection block 903 mounted on the slide rail 902, and a detection block reset mechanism 904 located behind the detection base 901. The detection block 903 is provided with a handle 905, a detection surface 9031 and a limiting surface 9032 at its front end, and scales 9033 on both sides of the detection block 903. An indicator needle 9011 is provided on the detection base 901. The span between the free state and the detection state of the mast detection unit 9 is approximately 20mm. The detection block 903 can be pushed forward using the handle 905 on top, or the handle behind the detection block reset mechanism 904. The detection block 903 has scales 9033 and indicator needles 9011 on both sides for easy reading of values. The long line in the middle is the 0 line, and the front and back are positive and negative. During detection, the limiting surface 9032 contacts the mast surface, and the front end of the detection surface 9031 enters the square hole of the mast. Free movement in and out indicates a qualified hole. When the readings of the three mast detection units 9 in each column are small and within the allowable range, the straightness and perpendicularity are considered qualified. If the hole heights of masts with different specifications of skids are different, the height of the crossbar 102 can be adjusted, or shims can be added below the mast detection unit 9 to meet the detection conditions. The step 10 is a separately provided stepped ladder for convenient inspection of the accuracy of high-level masts 13. Operators can stand on the step 10 to inspect the mast.

[0042] Reference Figure 1 The base frame 1 is also provided with an anti-fall block 103 to prevent the bearing of the main slide 2 from moving. The base frame 1 is provided with a forklift hole 104 for easy handling. The base frame 1 is provided with a plurality of leveling feet 105 for adjusting the levelness and stability.

[0043] The following will refer to Figures 1 to 11 The working principle of this invention will be explained.

[0044] First, determine the position of the X-axis positioning part 6 according to the skid specifications and install it. Simultaneously, keep the X-axis fixing part 4, Y-axis fixing part 5, and Y-axis positioning part 7 open. Next, push the skid 12 along the main slide rail 2 and side slide rail 3 until the front of the skid 12 hits the X-axis positioning part 6. Then, sequentially close the X-axis fixing part 4, Y-axis positioning part 7, and Y-axis fixing part 5 to ensure the skid 12 remains stable. Next, push each flatness detection part 8 to check if it is within the required accuracy range. Then, push each mast detection part 9 to check if it is within the required accuracy range. After all tests are completed, open the X-axis fixing part 4, Y-axis fixing part 5, and Y-axis positioning part 7, and manually remove the inspection fixture to complete the test. This double-mast skid accuracy testing device is compatible with testing NEV factory spare skids and genuine skids, has strong versatility, and can achieve a testing accuracy of ±1mm. The test results can be directly visualized.

[0045] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
