[0032] Reference Figures 1 to 5 A vacuum measuring fixture according to an embodiment of the present invention includes a base 100 and a worktable 101. The worktable 101 protrudes from the base 100 and has a recessed receiving cavity 110, in which a workpiece 120 is embedded. The receiving cavity 110 includes a first cavity 111, a second cavity 112, and a third cavity 113 that are interconnected, and the first cavity 111, the second cavity 112, and the third cavity 113 are respectively located on three adjacent outer wall surfaces of the worktable 101. It is understood that the bottom wall of the first cavity 111 is parallel to the horizontal plane and perpendicular to the bottom wall of the second cavity 112, and the bottom wall of the first cavity 111 is perpendicular to the bottom wall of the third cavity 113. Furthermore, the bottom walls of the second cavity 112 and the third cavity 113 have an included angle greater than 90° and less than 180°, and there is an arc-shaped connecting surface 119 between the bottom walls of the second cavity 112 and the third cavity 113, thereby adapting to the shape of the workpiece 120 and avoiding sharp corners between two adjacent feature areas of the workpiece 120. This facilitates ensuring the vacuum degree of the second cavity 112 and the third cavity 113, thereby further ensuring that the workpiece 120 fits against the bottom wall of the receiving cavity 110 and preventing the workpiece 120 from deforming.

[0033] It is understood that the first cavity 111, the second cavity 112 and the third cavity 113 are each provided with multiple air extraction holes 117. The air extraction holes 117 are connected to a vacuum pumping device. The vacuum pumping device can create a vacuum in the first cavity 111, the second cavity 112 and the third cavity 113 through the air extraction holes 117, so that the workpiece 120 fits in the receiving cavity 110 of the worktable 101, which can prevent the workpiece 120 from deforming and facilitate measurement.

[0034] Reference Figures 2 to 4 It is understood that the base 100 is provided with a vacuum chamber 103, and the base 100 is provided with a vacuum pipe 102. The vacuum pipe 102 is connected to a vacuum device, and the vacuum chamber 103 is connected to the vacuum pipe 102. The worktable 101 is provided with multiple air passages 104, which extend vertically. One end of the multiple air passages 104 is connected to the vacuum chamber 103, and the other end is connected to the vacuum port 117. The vacuum chamber 103 can ensure that the air pressure of the multiple air passages 104 tends to be consistent, thereby realizing the vacuum function.

[0035] It is understood that the workpiece 120 includes a base 121 embedded in the first cavity 111 and a skirt 122 embedded in the second cavity 112. Specifically, the skirt 122 includes a first side 125 embedded in the second cavity 112 and a second side 126 embedded in the third cavity 113. It is understood that the workpiece 120 is a thin-walled part made of flexible material such as silicone. Therefore, the depths of the first cavity 111 and the second cavity 112 are smaller than the thicknesses of the base 121 and the skirt 122, respectively, so that the outer wall of the workpiece 120 is higher than the outer peripheral wall of the worktable 101. This facilitates the thickness measurement of the workpiece 120, improves the accuracy of the measurement, and increases operational efficiency.

[0036] Reference Figure 2 and Figure 3 A first recess 123 is provided between the base 121 and the skirt 122. The first recess 123 is located above the connecting surface 119. The receiving cavity 110 is provided with a fourth cavity 114. The fourth cavity 114 is recessed in the first cavity 111. The first recess 123 is embedded in the fourth cavity 114. The bottom wall of the fourth cavity 114 is provided with an air extraction hole 117. The air extraction hole 117 can further fix the first recess 123 located on the base 121, thereby fixing the feature position of the workpiece 120, preventing deformation, and facilitating measurement.

[0037] Reference Figure 5 The base 121 is provided with a second recess 124, and the receiving cavity 110 is provided with a fifth cavity 115. The fifth cavity 115 is recessed in the first cavity 111, and the second recess 124 is embedded in the fifth cavity 115. The bottom wall of the fifth cavity 115 is provided with an air extraction hole 117. The air extraction hole 117 can ensure that the second recess 124 is stably embedded in the fifth cavity 115, so that the feature position of the workpiece 120 is fixed, preventing deformation and facilitating measurement.

[0038] Reference Figure 5 The base 121 has an outwardly extending extension 127 that extends in a direction away from the skirt 122. The receiving cavity 110 is provided with a sixth cavity 116 that extends outward from the first cavity 111 in a horizontal direction. The extension 127 is embedded in the sixth cavity 116. The bottom wall of the sixth cavity 116 has at least two air extraction holes 117. The air extraction holes 117 can ensure the vacuum degree of the sixth cavity 116, thereby ensuring that the extension 127 is stably embedded in the sixth cavity 116, thus fixing the feature position of the workpiece 120, preventing deformation, and facilitating measurement.

[0039] It is understandable that the workbench 101 is provided with a branch pipe 118 that connects the second cavity 112 and the third cavity 113. The branch pipe 118 extends in the horizontal direction and has an air extraction hole 117 at the end of the branch pipe 118, thereby enabling the skirt 122 of the workpiece 120 to be stably embedded in the second cavity 112 and the third cavity 113, and improving the stability of the workpiece 120 during measurement.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
