Due to the difficulty of positioning and inaccurate detection of curved surfaces, it is difficult to ensure the qualified rate of products required by the final assembly line if the detection of parts with curved surfaces is inaccurate, which affects the reliability and efficiency of final assembly.
[0003] In the prior art, complex curved parts are generally inspected using profiling fixtures. However, it is often difficult to manually inspect the surfaces of complex curved parts at different positions of the product.

[0027] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Please refer to Figures 1 to 6The utility model provides a curved surface part detection tooling, which needs to be used in conjunction with a three-coordinate measuring machine and needs to be placed on the three-coordinate measuring machine as a whole; specifically, the detection tooling can be placed on the three-coordinate measuring machine first, and then the curved surface part 9 can be installed on the detection tooling, and finally the three-coordinate measuring machine can be started to automatically detect the curved surface part 9.
[0029] like Figure 2 As shown, the detection tooling includes a base plate 1, and a plurality of support components 4 are installed in the middle of the base plate 1. The vertical heights of the support components 4 are not consistent, and the ends are adapted to the bottom of the curved part 9 to support the curved part 9 and limit the vertical height of the curved part 9.
[0030] like Figure 2 As shown, a plurality of quick side-thrust assemblies 8 and a plurality of quick clamping assemblies 5 are installed around the support assembly 4. The quick side-thrust assemblies 8 position the curved surface part 9 to prevent the curved surface part 9 from moving horizontally to the left and right, and restrict the horizontal direction of the curved surface part 9. The quick clamping assemblies 5 clamp the curved surface part 9 to completely fix the curved surface part 9 for measurement, thereby improving the measurement accuracy.
[0031] Furthermore, a plurality of reference blocks 2 are installed around the base plate 1, and a reference hole 21 is provided inside the reference block 2 for serving as a reference reference of a three-dimensional coordinate measuring machine. The degree of freedom of the curved part 9 is limited by the support assembly 4, the quick side thrust assembly 8 and the quick clamping assembly 5. At the same time, the reference blocks 2 and the reference holes 21 are added, thereby solving the problem that the curved part 9 is difficult to measure.
[0032] like Figure 4 As shown, the support assembly 4 includes a support column 41 mounted on the base plate 1 and a contact column 42 mounted on the support column 41 , and the end of the contact column 42 is adapted to the bottom surface of the curved part 9 .
[0033] Furthermore, the contact column 42 contacts the curved part 9 and is made of stainless steel material to increase its wear resistance and prevent the accuracy from being affected by friction due to long-term use; the support column 41 is made of aluminum alloy material to play a supporting role.
[0034] like Figure 5 As shown, the quick side-pushing assembly 8 includes a first supporting block 81 mounted on the base plate 1 and a push-pull quick clamp 82 mounted on the first supporting block 81. The push-pull quick clamp 82 belongs to the prior art and can be directly purchased and selected. The end of the push-pull quick clamp 82 outputs lateral reciprocating motion to push the side of the curved part 9 laterally and also limit the surrounding of the curved part 9.

[0037] like Figure 3 As shown, a plurality of shockproof rubber pads 7 are installed at the bottom of the base plate 1. The shockproof rubber pads 7 play a role in bottom surface support and shockproof, preventing the tooling from directly contacting and rubbing with the three-dimensional coordinate measuring machine to damage the standard marble platform, and also preventing the tooling from vibrating and affecting the accuracy.
[0038] like Figure 2 As shown, a reference coordinate value identification plate 3 is installed on one side of the reference block 2. The reference coordinate value identification plate 3 is an aluminum sheet. The reference coordinate value identification plate 3 is marked with the XYZ coordinate value of the reference hole 21, so as to facilitate coordinate verification during the detection process, thereby having better initial accuracy.
[0039] like Figure 6 As shown, a sealing cover 22 is installed on the upper part of the reference block 2 , and the sealing cover 22 is snap-fitted with the reference hole 21 to cover the reference hole 21 , thereby protecting the reference hole 21 and maintaining the accuracy of the reference hole 21 .
[0040] However, in this embodiment, the sealing cover 22 is connected to the base plate 1 via a rotating shaft, and a protrusion is provided on the sealing cover 22. By driving the protrusion, the sealing cover 22 rotates around the rotating shaft, thereby making it more convenient to open and close the sealing cover 22 and improving the opening and closing efficiency.
[0041] like Figure 5 As shown, a label 23 is installed on the bottom plate 1, and the label 23 is marked with tooling information; the label 23 is used to identify the specification, model, purpose or other information of the tooling.
[0042] During the use of the tooling: first, use the plastic handle 6 to carry the inspection tooling and place it on the marble workbench of the three-dimensional coordinate measuring machine, and the shockproof rubber pad 7 is in direct contact with the three-dimensional coordinate measuring machine; open the quick side push assembly 8 and the quick clamping assembly 5, and take out the curved surface part 9 that has been measured inside; secondly, place the curved surface part 9 to be inspected on the support assembly 4, and the end of the contact column 42 is in contact with the bottom surface of the curved surface part 9 to support the curved surface part 9; push the push-pull quick clamp 82, and the curved surface part 9 is The end of the push-pull quick clamp 82 outputs lateral reciprocating motion, pushes the side of the curved part 9 laterally, and also limits the surrounding of the curved part 9; again, pushes the fixed clamp 52, and the end of the fixed clamp 52 clamps the curved part 9, clamping the curved part 9 from top to bottom; finally, confirming that the curved part 9 can no longer move, the three-dimensional coordinate measuring machine starts working, and the three-dimensional coordinate measuring machine measures through the reference block 2, identifies the reference coordinates confirmed by the reference hole 21, and then starts to measure the size of the curved part 9.
