[0020] The utility model will be further described in detail below by means of the drawings and examples.

[0021] As Figures 1-2As shown: a three-dimensional profiler measured object fixed structure, including the clamp base (using conventional horizontal X-axis moving seat one 1 and Y-axis moving seat two 2), the upper side of the clamp base is pivoted with a rotating frame 4 through a support 3, and the middle part is provided with a clamping assembly 5 and serves as the area of the measured object clamping. The clamping assembly 5 includes a ring-shaped seat, a plurality of micro-cylinders 6 are installed on the circumference of the ring-shaped seat, and the inner side connected with the clamping block 7 can drive it. The clamping block 7 extends axially and can be used to clamp and fasten the measured object.

[0022] Referring to the accompanying drawings Figure 3 As shown, the outer side of each clamping block 7 is movably connected with a limiting buffer seat 8, and a plurality of limiting buffer seats 8 are independent of each other and have a spacing, wherein the limiting buffer seat 8 is made of a material with toughness (such as memory metal material), and the side wall of each limiting buffer seat 8 is provided with an arc-shaped slot, and the slots are arranged in a ring shape. A hoop 10 is movably arranged on the slot to bind, and the end of the hoop 10 has an open mouth, and the two ends of the open mouth extend outward for subsequent tightening adjustment. Specifically, the extension part adjusts the distance of the open mouth by using a bolt 11 and a nut assembly, so as to further limit the measured object inside each limiting buffer seat 8.

[0023] The limiting buffer seat 8 is connected with the clamping block 7 in a plug-in manner, that is, an arc-shaped socket 12 is formed on the top of the clamping block 7, and the bottom of the limiting buffer seat 8 is connected with a plug block of corresponding size. It should be noted that the inner side of the limiting buffer seat 8 is closer to the axis than the inner side of the clamping block 7, so that when the clamping block 7 moves inward to clamp the measured object, the limiting buffer seat 8 has already limited and stabilized the measured object in advance, and the position limitation is more convenient and accurate.

[0024] The limiting buffer seat 8 is provided mainly to consider that the acting force is difficult to control accurately when the clamping block 7 is pushed inward by the micro-cylinder 6 to clamp the measured object, and the limiting and shrinking of the limiting buffer seat 8 and the hoop 10 can effectively assist in clamping the measured object.

[0025] The inner side of the limiting buffer seat 8 is preferably provided with a layer of soft pad, which can protect the measured object inside to a certain extent, and can also increase the contact friction area with the measured object to further fasten.

[0026] Further, the bottom of the inner wall of the clamping block 7 is provided with a connecting seat 9, which is provided with the same socket 12 as the top of the clamping block 7, and the limiting buffer seat 8 can be plugged onto the connecting seat 9 as an internal binding unit. At this time, the hoop 10 needs to be removed, the limiting buffer seat 8 can be fixed by the radial movement of the clamping block 7, and the degree of extrusion deformation of the limiting buffer seat 8 can be used to adjust the size of the force applied by the micro-cylinder 6.

[0027] The above-mentioned embodiments are only used for illustrating the present application, and the related personnel can make various changes and modifications without departing from the scope of the present application. The present application is not limited to the content of the specification, and the scope of protection should be determined according to the claims.
