[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a tool for quickly inspecting the curvature of the appearance of mechanical parts, comprising a transverse dimension column 1, a movable collar 2, a longitudinal measuring ruler 3, a fixed clamping plate 4, a movable clamping plate 5, an anti-slip pad 6, a positioning bolt 7, a positioning nut 8, a limit window 9, a movable plate 10, an anti-slip column 11, a track groove 12, an extension clamping plate 13, a suction cup 14, a stabilizing protrusion 15, a stabilizing groove 16 and a fastening bolt 17. The transverse dimension column 1 is sleeved with a movable collar 2, a longitudinal measuring ruler 3 is fixed on one side of the movable collar 2, one end of the transverse dimension column 1 is connected and fixed to one end of the fixed clamping plate 4, and the other end of the transverse dimension column 1 passes through a hole opened at one end of the movable clamping plate 5. The fixed splint 4 and the movable splint 5 are fixed with anti-skid pads 6 on the opposite side surfaces, and the fixed splint 4 and the movable splint 5 are fixed with positioning bolts 7 on one end away from the side surface, and positioning nuts 8 are installed on the positioning bolts 7. The positioning bolts 7 pass through the limiting windows 9, and the limiting windows 9 are provided on the movable plate 10. An anti-slip column 11 is fixed at one end of the movable plate 10, and the anti-slip column 11 is fitted with one end of the inner wall of the track groove 12. The track groove 12 is provided on the fixed splint 4 and the movable splint 5 away from the side surface, and an extension splint 13 is fixedly installed on the other end of the movable plate 10, and a suction cup 14 is inlaid on one side of the extension splint 13, and a fastening bolt 17 is threadedly installed on one end of the movable splint 5.

[0021] In this example, a stabilizing protrusion 15 is fixedly installed on one side of the inner wall of the hole opened at one end of the movable splint 5, and the stabilizing protrusion 15 is in contact with the inner wall of the stabilizing groove 16. The stabilizing groove 16 is opened on one side of the transverse dimension column 1. The above-mentioned structural design enables the movable splint 5 to carry the stabilizing protrusion 15 along the stabilizing groove 16 for stable linear displacement adjustment.

[0022] The positioning bolt 7 is slidably connected to the limit window 9. The length of the limit window 9 is greater than half the length of the movable plate 10. The width of the movable plate 10 is greater than half the width of the fixed splint 4 and the movable splint 5. The above structural design ensures that the movable plate 10 can be stably adjusted in a linear displacement, and the displacement distance is sufficient to provide stable support for the extended splint 13.

[0023] The anti-slip column 11 and the track groove 12 are slidably connected. The side cross-sectional shapes of the anti-slip column 11 and the track groove 12 are both "T"-shaped. The length of the track groove 12 is greater than half the length of the movable plate 10. The above structural design can further limit the movable plate 10 to ensure the stability of the movable plate 10 during active adjustment and fixed use.

[0024] The diameter of the suction cup 14 is greater than half the side length of the extended clamping plate 13, and the center of the extended clamping plate 13 is on the same horizontal line as the centers of the fixed clamping plate 4 and the movable clamping plate 5. The above-mentioned structural design enables the suction cup 14 to stably adsorb and fit with the surface of the special-shaped part, thereby ensuring the device's clamping effect on the special-shaped part.

[0025] The stabilizing protrusion 15 is slidably connected to the stabilizing groove 16. The length of the stabilizing groove 16 is greater than 3 / 4 of the length of the transverse dimension column 1. The above structural design ensures that the movable clamping plate 5 can be smoothly adjusted for long-distance linear displacement and ensures that the movable clamping plate 5 will not rotate.

[0026] Working principle: When using this device, if the size of the mechanical parts to be inspected is small, tighten the positioning nuts 8 installed on the far side of the fixed clamping plate 4 and the movable clamping plate 5, and the positioning nuts 8 squeeze the movable plate 10 to fit and fix with the fixed clamping plate 4 and the movable clamping plate 5, fix the position of the movable plate 10 and the extension clamping plate 13, and move the movable clamping plate 5 to slide along the transverse dimension column 1 until the anti-slip pad 6 on the opposite side of the fixed clamping plate 4 and the movable clamping plate 5 or the suction cups 14 installed on the two extension clamping plates 13 fit tightly with the two ends of the mechanical parts, rotate the fastening bolts 17 to squeeze the transverse dimension column 1 to fix the position of the movable clamping plate 5, complete the clamping of the mechanical parts, and then start normal inspection;

[0027] If the size of the mechanical part to be inspected is large, the extension splint 13 is pulled away from the fixed splint 4 and the movable splint 5, and the extension splint 13 brings the movable plate 10 away from the ends of the fixed splint 4 and the movable splint 5 in a straight line. The limit window 9 opened on the movable plate 10 slides relative to the positioning bolt 7, and the anti-slip column 11 also slides in a straight line along the track groove 12 until the extension splint 13 extends to a suitable distance. The positioning nut 8 is rotated to squeeze the movable plate 10 and the fixed splint 4 and the movable splint 5 to fit and fix them. The suction cups 14 installed on the two extension splints 13 are brought close to the two ends of the mechanical part, and the movable splint 5 is pushed to slide along the transverse dimension column 1 until the two suction cups 14 are stably adsorbed and fitted with the two ends of the mechanical part respectively. The fastening bolts 17 are rotated to squeeze the transverse dimension column 1 to fix the position of the movable splint 5, and the clamping of the mechanical part is completed, and normal inspection can be started. This is the working principle of the rapid inspection tool for the curvature of the mechanical part shape.
