[0026] Example 1

[0027] The assembly accuracy testing tool disclosed in this utility model will be described below with reference to the accompanying drawings, as shown in the attached drawings. Figure 1 Appendix Figure 2 As shown, the assembly accuracy testing tool includes a base frame 100, on which two abutment components 200 and a measuring gauge 300 are provided. Each abutment component 200 includes at least an abutment shaft 210. The axial direction of the abutment shaft 210 is perpendicular to the axial direction of the probe 310 of the measuring gauge 300, and the front end of the probe 310 of the measuring gauge 300 faces away from the abutment component 200. The distance between the two abutment shafts 210 and the probe 310 is the same, and the area facing away from the probe 310 on the side of the two abutment shafts 210 is a spherical or arcuate surface. The spherical or arcuate surfaces of the two abutment shafts 210 are tangent to a surface 400 perpendicular to the axis of the probe 310.

[0028] The structure of the base frame 100 can be designed as needed. In this embodiment, as shown in the attached diagram... Figure 1 Appendix Figure 2 As shown, the base frame 100 includes a base plate 110 and a mounting plate 120 perpendicularly connected to the base plate. The abutment component 200 is mounted on the base plate 110, which can be a flat plate with a certain thickness. The mounting plate is used to mount the measuring instrument 300, and it can be directly screwed to the top surface of the base plate. The length of the mounting plate 120 can be designed as needed and is not limited here.

[0029] More preferably, in order to facilitate the adjustment of the detection position of the measuring instrument 300 on the mounting plate 120, as shown in the attached... Figure 2As shown, the mounting plate is positioned on the base plate 110 such that its position can be adjusted along its length. For ease of adjustment, a mounting slot 111 is provided on the base plate 110. The mounting plate matches the shape of the mounting slot and is fastened to the base plate with screws. Simultaneously, a strip-shaped hole 121 is provided on the mounting plate 120, the length direction of which is consistent with the length direction of the mounting plate 120. A screw hole 113 corresponding to the strip-shaped hole is provided in the mounting slot 111.

[0030] As attached Figure 1 Appendix Figure 3 As shown, the abutment shaft 210 is vertically fixed on the substrate. The abutment shaft 210 can be a round shaft, a semi-circular shaft, or a sphere. The abutment shaft 210 can be located at the bottom or top of the substrate 110. Preferably, the abutment shaft 210 and the measuring instrument are located on opposite sides of the substrate 110. For example, when the measuring instrument 300 is located above the substrate, the abutment shaft 210 is located at the bottom of the substrate.

[0031] To ensure the detection accuracy, the abutment shaft 210 is more stably mounted on the substrate. A screw hole extending downward from its top to a certain depth is concentrically provided on the abutment shaft 210. The substrate 110 is provided with a connecting hole 112 for connecting the abutment shaft. The connecting hole 112 is I-shaped. The abutment shaft 210 is inserted into the lower part of the connecting hole and fastened to the substrate 110 by a bolt 500 screwed into the screw hole at the top of the abutment shaft.

[0032] The measuring instrument 300 is installed on the upper end of the mounting plate 120. The measuring instrument 300 can be selected as needed, such as a micrometer, dial indicator, or ten-thousand-meter indicator. The specific size of the measuring instrument 300 can also be selected as needed and is not limited here.

[0033] As attached Figure 3 Appendix Figure 4 As shown, each of the abutment shafts 210 is coaxially equipped with a roller 220 or a ball bearing. Taking roller 220 as an example, the roller 220 is rotatably mounted on the abutment shaft via a bearing 230. The height of the roller 220 can be set as needed and is not limited here. Furthermore, the rollers 220 on the two abutment shafts can be the same size or different sizes. When the two rollers 220 are the same size, they are symmetrically distributed on both sides of the measuring instrument 300. When the two rollers 220 are different sizes, they are not symmetrically distributed on both sides of the measuring instrument 300. In this case, the side facing away from the probe 310 is kept flush.

[0034] During testing, if attached Figure 5 Appendix Figure 6 As shown, the circumferential surfaces of the two rollers 220 can be brought into contact with the first side 01 of the lower first track, and the front end of the measuring instrument's probe can be brought into contact with the second side 02 of the higher second track. The measuring instrument reading is then read and compared with a threshold to determine if the horizontal distance between the first and second sides meets the requirements. Alternatively, if the contact assembly does not have rollers, i.e., only contact shafts, then during testing, the spherical or arcuate surfaces of the two contact shafts are brought into contact with the first side 01, and the front end of the measuring instrument's probe is brought into contact with the second side 02. The measuring instrument reading is then read and compared with a threshold to determine if the horizontal distance between the first and second sides meets the requirements.

[0035] As attached Figure 4 As shown, to facilitate full contact between the two rollers 220 and the first or second side to be tested, a wear-resistant plate 600 is provided on the substrate 110. The wear-resistant plate and the abutment assembly are located on the same side of the substrate, and the wear-resistant plate and the probe are located on opposite sides of the two abutment assemblies. The wear-resistant plate can be connected to the substrate by gluing, screwing, or other methods. The wear-resistant plate 600 can be, for example, made of polytetrafluoroethylene (PTFE), or other feasible materials, which are not limited here. For example, during testing, the bottom surface of the wear-resistant plate 600 is attached to the top surface of the first track, so that the abutment shaft 210 can be stably extended in the vertical direction, thereby ensuring that the circumferential surface or spherical surface of the rollers 220 fully and accurately contacts the first side 01 of the first track.

[0036] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
