Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 - Figure 4As shown, this utility model provides a quick clamping fixture for measuring irregularly shaped parts, including a base 1. The surface of the base 1 is provided with a convenient assembly / disassembly component 2. The convenient assembly / disassembly component 2 includes a mounting groove 201, which is located on the top of the base 1. A connecting block 203 is inserted into the mounting groove 201. Insertion holes 204 are provided on both outer surfaces of the connecting block 203. A rectangular block 202 is connected to the top of the connecting block 203. A bidirectional screw 205 and a sliding rod 206 are respectively inserted into the interior of both sides of the base 1. Two sets of moving plates 209 are symmetrically connected to the surface of the bidirectional screw 205. Insertion holes 204 are provided on both sides of the moving plates 209. The threaded hole 210 and the sliding hole 211 are connected to the inner sides of the two sets of moving plates 209, and the two ends of the bidirectional screw 205 are respectively connected to the bearing 207 and the handle 208. The bearing 207 and the bidirectional screw 205 form a rotatable connection, and the bidirectional screw 205 and the handle 208 form a fixed connection. The bidirectional screw 205 is bolted to the moving plate 209 through the threaded hole 210, and the moving plate 209 is slidably connected to the sliding rod 206 through the sliding hole 211. The position and size of the insert 212 match the position and size of the insertion hole 204, and the insert 212 and the insertion hole 204 form an insertion connection.

[0025] The overall effect of Embodiment 1 is that, when measuring irregularly shaped parts of different models, the handle 208 can be rotated in the opposite direction to drive the bidirectional screw 205 to rotate in the opposite direction. Simultaneously, the bidirectional screw 205 rotates in the opposite direction, and through the threaded hole 210, it also rotates in the opposite direction with the two sets of moving plates 209. This causes the two sets of moving plates 209 to retract to both sides simultaneously, pulling the insert block 212 out of the insert hole 204. Then, the existing rectangular block 202, along with the connecting block 203, can be removed from the surface of the mounting groove 201. Finally, the required mounting rectangular block 202 is pushed into the mounting groove 201, causing the bottom of the new rectangular block 202 to connect... Block 203 can be inserted into the mounting slot 201. Then, rotating the handle 208 forward drives the bidirectional screw 205 to rotate forward, so that the two sets of moving plates 209 can move inward simultaneously through the screw rotation, driving the insert block 212 to be inserted into the insertion hole 204 for fixation. After that, the corresponding irregular parts can be fixed by the rectangular block 202, and the size can be measured by the image instrument. By replacing different rectangular blocks 202, it is possible to clamp and measure irregular parts of different shapes, which improves the overall practicality and flexibility of use. The method of fixing the rectangular block 202 with the irregular parts is the existing public technology, which will not be described in detail here.

[0026] Example 2, as Figure 1 and Figure 5As shown, the base 1 is equipped with a portable handling component 3. The portable handling component 3 includes a groove 301. Springs 302 are provided on both sides of the inner wall of the groove 301. The rear ends of the two sets of springs 302 are connected to handles 303. The handles 303 and the springs 302 form an elastic structure.

[0027] The effect achieved by the entire embodiment 2 is that when the base 1 is being moved, the handle 303 can be pulled out from the groove 301 and the base 1 can be moved by grasping the handle 303. After the base 1 is moved to the designated location, the handle 303 is released, so that the spring 302 can push the handle 303 to retract into the groove 301 for hiding, thus avoiding the inconvenience or danger caused by the handle 303 protruding when not needed.

[0028] Working principle: When measuring irregularly shaped parts of different shapes, the rectangular block 202 can be disassembled by rotating the handle 208, and then the corresponding rectangular block 202 can be installed on the surface of the base 1. This enables the clamping and measurement of irregularly shaped parts of different shapes, improving the overall practicality and flexibility of use. When moving the base 1, it can be moved by the handle 303. When it is not needed to move, the handle 303 will automatically retract to avoid the problem that the smooth surface of the base 1 is not convenient for moving.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
