[0014] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0015] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0016] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0017] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0018] Furthermore, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] See also Figure 1-Figure 2 The present embodiment provides a three-coordinate inspection tool for special-shaped parts, including a base plate 10, a vertical plate 11 is arranged on the base plate 10, the vertical plate 11 is a plate-like structure with a roughly triangular structure and a hollow interior, a fixing bar 12 is arranged on the base plate inside the vertical plate 11, and a positioning plate 14 is connected to the fixing bar 12 by a plurality of connecting screws 13, and the positioning plate 14 is used to place the parts to be inspected.

[0021] Specifically, the upper end of the positioning plate 14 is roughly fan-shaped and has three connecting ends 141. Each connecting end 141 is connected to a pressure plate 143 through a support column 142. A support groove 144 for placing parts is formed between the pressure plate 143 and the connecting end 141. The pressure plate 143 is connected to the support column 142 through a screw 145. The screw 145 is a semi-threaded structure, and a spring 146 is sleeved on it to achieve stable compression of the parts.

[0022] In order to be compatible with special-shaped parts of different specifications, when the special-shaped parts to be inspected are large in size and heavy in weight, a thickened plate 15 is set on one side of the bottom of the positioning plate 14, and a connecting groove 147 is opened at the bottom of the positioning plate 14 and the thickened plate 15. The connecting screw 13 passes through the connecting groove 147 to tighten the positioning plate. By opening the connecting groove 147, it is possible to replace the positioning plate without unscrewing the connecting screw, thereby improving the replacement efficiency. At the same time, due to the presence of the thickened block, the connecting screw 13 has a certain length to meet the connection requirements.

[0023] In order to quickly place the parts on the vertical plate 11, a positioning shaft 16 is set at the top of the vertical plate 11 for positioning the inner hole of the part, and a clamping structure is set on the vertical plate above the positioning shaft 16. The clamping structure adopts a conventional quick clamp 17 to press the part toward the positioning shaft from above.

[0024] An L-shaped limit plate 18 is set on the side of the vertical plate 11, and a locking screw 19 is set on the L-shaped limit plate 18. After the parts are placed, the parts are locked and positioned from one side by the locking screw 19. At the same time, a limit block 20 is also set on the bottom plate 10 for limiting the parts from the bottom.

[0025] See also Figure 1 and Figure 3 When parts need to be inspected, the positioning plate 14 that matches the part to be inspected is first fixed to the fixing bar 12 through the connecting screws 13, and then the part to be inspected 21 is placed in the support groove, the inner hole above the part is installed on the positioning shaft 16, and fixed by the quick clamp 17, and the locking screw 19 is tightened on the side to fix it.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
