Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] By providing the disassembly mechanism 2, the fixing frame 8 can be quickly disassembled and installed conveniently, thus avoiding the problem that the fixing frame and the bracket are complicated to install and disassemble, making it impossible to fix different types of workpieces, resulting in the workpieces falling off from the inner side of the fixing frame 8 during the inspection process due to loose fixation between the workpieces and the fixing frame 8, thereby affecting the inspection data of the workpieces.

[0030] Example 2

[0031] In one embodiment, the slot 201 is opened at the top of the rotating block 4, and the bottom of the slot 201 is movably connected with a rotating disk 202. The top of the rotating disk 202 is provided with a movable groove 203, and the outer side of the rotating disk 202 is provided with an insertion rod 204. The inner side of the insertion rod 204 is movably connected to the inner cavity of the movable groove 203 through a rotating shaft. The bottom of the fixed frame 8 is inserted into the inner cavity of the slot 201, and the inner cavity of the slot 201 and the bottom of the fixed frame 8 are both provided with a socket 9. The insertion rod 204 is inserted into the inner cavity of the socket 9. The bottom of the inner cavity of the slot 201 is provided with a limiting groove 207, and the bottom of the insertion rod 204 is fixedly installed with a limiting block 208, and the bottom of the limiting block 208 is slidably connected to the inner cavity of the limiting groove 207. The bottom of the rotating disk 202 is fixedly installed with a handle 205, and the inner surfaces on the left and right sides of the handle 205 are movably connected with suction cups 206, and the top of the suction cup 206 is adsorbed on the bottom of the rotating block 4.

[0032] By providing the insertion rod 204 and the socket 9, the fixing frame 8 can be disassembled and replaced, and different types of fixing frames 8 can be conveniently replaced according to the type of the workpiece to be processed, so as to avoid the workpiece falling off from the inner side of the fixing frame 8 due to the mismatch between the shape and the fixing frame 8 when the fixing frame 8 is fixing the workpiece. By providing the limit block 208 and the limit groove 207, the moving direction of the insertion rod 204 can be limited to avoid the insertion rod 204 from being offset when moving, and then the fixing frame 8 cannot be fixed. By providing the suction cup 206, the rotation angle of the rotating disk 202 can be fixed, so as to avoid the rotating disk 202 shaking when the rotating block 4 and the fixing frame 8 drive the workpiece to rotate, so that the insertion rod 204 moves out of the inner cavity of the socket 9, causing the fixing frame 8 to fall off.

[0033] Example 3

[0034] In one embodiment, a motor 301 is fixedly mounted at the bottom of an L-shaped plate 10, a driving shaft 302 is fixedly connected to the output end of the motor 301, a driven shaft 303 is movably connected to the front and rear sides and the right side of the bottom of the testing platform 1, a transmission belt 304 is movably connected to the outer surfaces of the driving shaft 302 and the driven shaft 303, a connecting rod 305 is fixedly mounted on the top of the driving shaft 302 and the driven shaft 303, a driving bevel gear 306 is fixedly mounted on the upper and lower sides of the outer surface of the connecting rod 305, a driven bevel gear 307 is fixedly mounted on the upper and lower sides of the outer surface of the rotating block 4, the outer side of the driven bevel gear 307 is meshed with the inner side of the driving bevel gear 306, a sliding groove 308 is provided on the top of the testing platform 1, a sliding rod 309 is fixedly mounted on the bottom of the rotating block 4, the bottom of the sliding rod 309 is slidably connected to the inner cavity of the sliding groove 308, a bottom plate 6 is fixedly mounted on the bottom of the support rod 5, and a bolt 7 is threadedly connected to the top of the bottom plate 6.

[0035] By setting up the adjustment mechanism 3, the workpiece can be driven to rotate, which is convenient for multi-angle detection of the workpiece. By setting up the sliding rod 309 and the sliding groove 308, the rotating block 4 can be supported and limited at the same time to prevent it from shifting during rotation, and then failing to drive the workpiece for multi-angle detection. By setting up the bolt 7, the whole equipment can be stabilized to avoid the whole shaking due to external collision, so that the workpiece can be prevented from falling from the inside of the fixed frame 8.

[0036] When the utility model is at work: according to the shape of the workpiece, the bottom of the matching fixing frame 8 is inserted into the inner cavity of the slot 201, and then the handle 205 is grasped and rotated. At this time, the rotating disk 202 rotates synchronously and drives the insertion rod 204 to move outward, so that the insertion rod 204 is inserted into the inner cavity of the insertion hole 9 to complete the fixation of the fixing frame 8, and then the suction cup 206 is grasped and pushed upward. The suction force of the suction cup 206 is used to limit the rotating disk 202 to prevent the insertion rod 204 from escaping from the inner cavity of the insertion hole 9. Then, after the workpiece is placed on the inner side of the fixing frame 8 and fixed, the output end of the motor 301 drives the active rotating shaft 302 to rotate, and through the mutual cooperation with the driven rotating shaft 303 and the transmission belt 304, the connecting rod 305 drives the active bevel gear 306 and the rotating block 4 to rotate, and then the fixing frame 8 and the workpiece rotate synchronously to complete the angle adjustment of the workpiece.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
