Description

Technical Field

[0001] This utility model relates to the field of coordinate measuring machine technology, specifically to a coordinate measuring machine with a multi-angle adjustment platform. Background Technology

[0002] A coordinate measuring machine (CMM), also known as a coordinate measuring machine or coordinate measuring bed, is an instrument capable of measuring geometric shapes, lengths, and circumferential divisions within a six-sided spatial area. It can be defined as a detector that can move in three directions. This detector can move on three mutually perpendicular guide rails and transmit signals in a contact or non-contact manner. The displacement measurement system of the three axes (such as an optical scale) receives these signals and calculates the coordinates (x, y, z) of each point on the workpiece and various functional measurement values ​​through a data processor or computer.

[0003] The placement platform in existing coordinate measuring machines is generally a fixed platform structure. When performing workpiece positioning measurement, the workpiece is placed directly on the platform. However, when measuring different surfaces of the workpiece or workpieces with holes, the workpiece is usually flipped manually to measure the diameter of each hole, which is cumbersome and not convenient for measuring inclined structures.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1-3 It can be seen that the instrument includes a base 1, a slide rail 2 is fixed on the top of the base 1, a connecting platform 3 is slidably mounted on the upper side of the slide rail 2, a coordinate measuring mechanism 4 is mounted on the upper side of the base 1 above the connecting platform 3, an adjustment platform structure is mounted on the upper side of the connecting platform 3, the adjustment platform structure includes a base plate 5 fixed to the upper side of the connecting platform 3 by connecting nails, a circular frame 6 is fixed on the upper side of the base plate 5, a limit ring 7 is fixed on the top of the inner side of the circular frame 6 to limit the position of the truncated cone 8, the truncated cone 8 is rotatably mounted inside the circular frame 6, and the truncated cone 8 can only rotate 360 ​​degrees. The reciprocating rotation within a certain range cannot maintain rotation in the same direction. The truncated cone 8 has a worm gear groove 8.1 on its side edge. The circular frame 6 has a connecting shaft 9 rotatably mounted on its side. The base plate 5 has a motor 23 fixed on its upper side. The output end of the motor 23 is fixed to one end of the connecting shaft 9 so as to drive the worm 10 to rotate. The connecting shaft 9 has a worm 10 fixed in the middle that meshes with the worm gear groove 8.1, which can drive the truncated cone 8 to rotate. The truncated cone 8 has a telescopic rod 11 fixed on its upper side. The top of the telescopic rod 11 has a placement platform 12 fixed on it for placing workpieces.

[0022] Combined with appendix Figure 2 , 4It can be seen that a pair of support frames 13 are fixed on the upper side of the base plate 5. A limit frame 14 is fixed at the top of the support frame 13. A motor 24 is fixed on one side of the limit frame 14. The output end of the motor 24 is fixed to one end of a bidirectional threaded screw 15 so as to drive the bidirectional threaded screw 15 to rotate. The bidirectional threaded screw 15 is rotatably provided inside the limit frame 14. A pair of sliding blocks 16 are threadedly connected to the outside of the bidirectional threaded screw 15, which can drive the pair of sliding blocks 16 to move in different directions. A clamping rod 17 is fixed on one side of the sliding block 16. A rotating part of the clamping rod 17 is provided at one end. A rotating shaft 18 has a clamping pad 19 fixed at one end. A pair of clamping pads 19 are located directly above the placement platform 12 to facilitate the stable placement of the workpiece and to clamp the workpiece. A bevel gear 20 is fixed at the other end. A micro motor 21 is fixed on the side of the clamping rod 17. A bevel gear 22 that meshes with the bevel gear 20 is fixed at the output end of the micro motor 21.

The motor 23, the motor 24, the micro motor 21, and the telescopic rod 11 are electrically connected to an external power source.

[0023] The working principle of this application is as follows: When measuring the size of the workpiece, the adjustment platform structure is first fixed above the connecting table 3 by connecting nails. Then the workpiece is placed on the placement table 12. The initial position of the placement table 12 is higher than the limit frame 14. Then the coordinate measuring mechanism 4 is started to position and measure the workpiece. When it is necessary to measure different surfaces of the workpiece, the motor 23 can be started to drive the connecting shaft 9 to rotate, so as to drive the truncated cone 8 to rotate through the worm gear 10, thereby driving the workpiece to rotate and measure different surfaces.

[0024] When it is necessary to flip the workpiece, the telescopic rod 11 can be activated to move the workpiece downwards. Then, the motor 24 is activated, which drives the bidirectional threaded screw 15 to rotate, so as to synchronously drive a pair of sliding blocks 16 to move, thereby clamping the workpiece with the clamping pad 19. Then, the telescopic rod 11 continues to move the placement table 12 downwards, so that the workpiece is released from the placement table 12. Then, the micro motor 21 is activated to drive the bevel gear 22 to rotate, which drives the clamping pad 19 to rotate through the bevel gear 20, so as to flip the workpiece. After the flipping is completed, the placement table 12 can be raised to catch the workpiece. Then, the sliding blocks 16 are moved to both ends of the bidirectional threaded screw 15, and the placement table 12 is raised again to measure the workpiece.

[0025] If it is necessary to measure the diameter of the inclined hole, the clamping pad 19 can be kept at a certain angle when clamping the workpiece, and the coordinate measuring mechanism 4 can be moved down to facilitate the measurement of the inclined hole diameter.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
