[0032] Example: Reference Figure 1-5An optical measuring instrument bracket shown in the figure comprises a base plate 1, a mounting plate 2 and a vertical plate 3 are fixed on the upper surface of the base plate 1, a rotating shaft 4 is rotatably connected to the vertical plate 3, a transmission assembly 5 is fixed to one end of the rotating shaft 4, a horizontal electric push rod 9 and a vertical electric push rod 10 are fixedly installed on the top and side surfaces of the mounting plate 2 respectively through brackets, and the output ends of the horizontal electric push rod 9 and the vertical electric push rod 10 are both slidably penetrated through the mounting plate 2 and fixed with a fixing plate 11 for mounting the measuring instrument;

[0033] The transmission assembly 5 includes a driving frame 51 fixed to one end of the rotating shaft 4, a bidirectional threaded screw 52 is rotatably connected in the driving frame 51, and two lifting plates 57 are slidably matched in the driving frame 51, the bidirectional threaded screw 52 passes through the two lifting plates 57 and is threadedly connected to the two lifting plates 57, one end of the two lifting plates 57 is fixed with a turning seat 54, and the two turning seats 54 are rotatably connected with a connecting plate 55, the turning seat 54 can drive the connecting plate 55 to turn 90° to one side, the two connecting plates 55 are respectively fixedly connected with an upper clamping plate 6 and a lower clamping plate 7, the top of the lower clamping plate 7 is rotatably connected with a rotating table 8, and the upper surface of the rotating table 8 is provided with a placement groove for positioning the workpiece.

[0034] When the optical measuring instrument bracket is used to detect a workpiece, the measuring instrument a13 and the measuring instrument b14 are respectively installed on the two fixed plates 11, and the bottom of the workpiece to be measured is placed in the placement groove of the rotating table 8. The two lifting plates 57 can be driven to approach each other by the rotation of the bidirectional threaded screw 52, ​​and the two flip seats 54 move synchronously with the lifting plates 57, so that the upper clamping plate 6 and the lower clamping plate 7 can approach each other and quickly clamp and fix the workpiece. At this time, the workpiece rises to the side of the measuring instrument b14 with the lower clamping plate 7. The setting of the placement groove can make one side of the workpiece perpendicular to the measuring instrument b14, and the flip seat 54 at the top drives the connecting plate 55 and the upper clamping plate 6 connected to the connecting plate 55 are flipped upward from the horizontal state to the vertical state, so that the top surface of the workpiece on the upper surface of the rotating table 8 is exposed. At this time, the vertical electric push rod 10 drives the measuring instrument a13 to descend vertically to perform optical measurement on the upper surface of the workpiece. When the measuring instrument a13 completes the measurement, the vertical electric push rod 10 drives the measuring instrument a13 to rise. At this time, the measuring instrument b14 is controlled by the horizontal electric push rod 9 to approach the workpiece. The rotation of the rotating table 8 can drive the workpiece to rotate to different angles, so that the measuring instrument b14 can perform optical measurement on different sides of the workpiece. When the side of the workpiece is measured, the horizontal electric push rod 9 is used to control the measuring instrument b14 to move closer to the workpiece.

At this time, the lower clamping plate 7 is located directly above the upper clamping plate 6, and the lower clamping plate 7 and the upper clamping plate 6 are separated from each other by a distance, so that the bottom of the workpiece is separated from the placement groove of the rotating table 8, and then the connecting plate 55 connected to the lower clamping plate 7 is controlled to flip through the flip seat 54, so that the lower clamping plate 7 is flipped upward to a vertical state, and the bottom surface of the workpiece is exposed, so that the workpiece is automatically flipped over without manual flipping. At this time, the vertical electric push rod 10 pushes the measuring instrument a13 downward again, and optically measures the bottom surface of the workpiece, so as to complete the flipping of the workpiece and the optical measurement of the top surface, bottom surface and side surface of the workpiece. After the measurement is completed, the measuring instrument a13 rises to the initial position driven by the vertical electric push rod 10, and the lower clamping plate 7 is flipped downward to a horizontal state. After the upper clamping plate 6 and the lower clamping plate 7 clamp the workpiece and flip it 180°, the upper clamping plate 6 and the lower clamping plate 7 move away from each other again, and the operator can take out the measured workpiece.

[0036] In order to make the measuring instrument a13 rise and fall vertically and make the measuring instrument b14 move horizontally, preferably, in this embodiment, the spatial positions of the horizontal electric push rod 9 and the vertical electric push rod 10 are perpendicular to each other, and a second guide rod 12 is fixed to one side of the fixed plate 11, and one end of the second guide rod 12 slides through the mounting plate 2. The setting of the second guide rod 12 can make the vertical electric push rod 10 drive the measuring instrument a13 to rise and fall vertically, and make the horizontal electric push rod 9 drive the measuring instrument b14 to move horizontally.

[0037] In order to drive the bidirectional threaded screw 52 to rotate, so that the bidirectional threaded screw 52 drives the two lifting plates 57 to move closer to or away from each other, so that the flip seat 54 can drive the connecting plate 55 to flip 90° to one side, in this embodiment, a first servo motor 53 is fixed to one end of the driving frame 51 through a bracket, and the rotating shaft of the first servo motor 53 is fixedly connected to one end of the bidirectional threaded screw 52 through a coupling. The bidirectional threaded screw 52 is provided with two symmetrical threads with opposite rotation directions, and the two lifting plates 57 are respectively adapted to the two threads on the bidirectional threaded screw 52. Two first guide rods 58 are fixed in the driving frame 51, and the first guide rods 58 slide through the lifting plates 57. The two flip seats 54 are symmetrically arranged relative to the driving frame 51, and a second servo motor 56 is installed at one end of the flip seat 54 through a bracket.
