The bottom of the threaded rod 11 is rotatably connected to the bottom of the inner bottom of the rectangular groove 9 on the left side of the mounting seat 2, and a guide rod 12 is installed between the inner bottom and the inner top of the rectangular groove 9 on the right side of the mounting seat 2. The outer wall of the threaded rod 11 is threadedly connected to a threaded block 10, and the outer wall of the guide rod 12 is slidably connected to a rectangular block 13. Motor 3 20 is installed on the outer wall of the rectangular block 13 and the threaded block 10 away from the rectangular groove 9. The output ends of the two groups of motors 3 20 are both installed It is equipped with a hydraulic rod 21, and the output ends of the two groups of hydraulic rods 21 are both installed with a splint 22. A casting 7 is clamped and connected between the two groups of splints 22. A limiting component 8 is installed on the top of the mounting seat 2, and the limiting component 8 is connected to an arc plate 4. Several groups of three-coordinate measuring instrument cameras 15 are evenly installed on the inner wall of the arc plate 4. A locking component 14 is installed between the limiting component 8 and the front end outer wall of the mounting seat 2. A driving component 6 is provided on the top of the base plate 1 directly below the mounting seat 2, and the driving component 6 is connected to a motor 2 5. A hydraulic rod 18 is installed on the output end of the motor 2 5, and a splint 17 is installed on the output end of the hydraulic rod 18. A control device 19 is installed on the outer wall of the mounting seat 2, and the control device 19 is electrically connected to the three-coordinate measuring instrument camera 15.

[0022] The limiting assembly 8 includes a limiting groove 82, which is opened on the outer wall of the front end of the mounting seat 2 and passes through the inner bottom of the mounting seat 2. The inner wall of the limiting groove 82 is plugged into the limiting strip 81, and the bottom of the limiting strip 81 is connected to the outer wall of the curved plate 4. When the three-dimensional coordinate measuring machine camera 15 needs to be replaced, the limiting strip 81 with the curved plate 4 installed can be pulled out from the limiting groove 82.

[0023] The locking assembly 14 includes a rotating shaft 141, which is installed on the outer wall of the mounting base 2 near the entrance end of the limiting groove 82. The outer wall of the rotating shaft 141 is rotatably connected to the limiting plate 143. The other end of the limiting plate 143 is fixedly connected to the outer wall of the mounting base 2 by a bolt 142. The rear side of the limiting plate 143 is in contact with the outer wall of the limiting strip 81. By loosening the bolt 142, the limiting plate 143 can be removed from the entrance end of the limiting groove 82, thereby facilitating the removal of the limiting strip 81.

[0024] The driving assembly 6 includes a slide groove 61, which is opened on the top of the base plate 1. A bidirectional threaded rod 62 is rotatably connected between the inner walls of the front and rear ends of the slide groove 61. One end of the bidirectional threaded rod 62 is connected to the driving device, and both ends of the bidirectional threaded rod 62 are threadedly connected to a slider 63.

[0025] A rectangular plate 64 is installed on the top of the two groups of sliders 63. The outer wall of the rectangular plate 64 is connected to the motor 2 5. The output end of the motor 2 5 passes through the rectangular plate 64. When it is necessary to inspect the left and right sides of the casting 7, the bidirectional threaded rod 62 is driven by the driving device to rotate continuously, and the two groups of rectangular plates 64 are driven to approach each other along the slide groove 61 through the two groups of sliders 63.

[0026] The outer walls of the first and second clamping plates 17 and 22 close to the casting 7 are both provided with anti-slip strips 16 , and the provision of the anti-slip strips 16 increases the friction between the clamping plates and the casting 7 .

[0027] The working principle of the tooling for inspecting the size of large agricultural machinery castings provided by the present invention is as follows: after the casting 7 to be processed is placed on the base plate 1 just below the mounting seat 2, the output ends of the two groups of hydraulic rods 21 push the clamping plate 2 22 to clamp the casting 7 tightly, and then the output end of the motor 1 3 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the motor 3 20 and the hydraulic rod 2 21 to move upward along the rectangular slot 9 through the threaded block 10. After the casting 7 is moved to a certain height, the motor 1 3 stops working, and the output end of the motor 3 20 drives the casting 7 to rotate through the hydraulic rod 2 21 and the clamping plate 2 22. At this time, several groups of three-dimensional coordinate measuring machine cameras 15 inside the arc plate 4 below the mounting seat 2 will continuously scan the contour of the casting 7 , and transmits the data to the inside of the control device 19. When the contour scanning of the front and rear outer walls of the casting 7 is completed, the driving component 6 drives the two groups of hydraulic rods 18 to continuously approach the front and rear ends of the casting 7. After moving to a certain position, the output ends of the two groups of hydraulic rods 18 push the clamping plate 17 to limit the front and rear outer walls of the casting 7. Then the hydraulic rod 21 retracts the clamping plate 22, and then drives the motor 2 5 so that its output end drives the casting 7 to rotate in a circle in the left and right directions through the hydraulic rod 18 and the clamping plate 17. At the same time, the three-dimensional coordinate measuring machine camera 15 scans the contours of the remaining parts of the casting 7. When the three-dimensional coordinate measuring machine camera 15 needs to be replaced, open the locking component 14 and remove the limit component 8 with the arc plate 4 installed from the mounting seat 2.

[0028] Compared with the related art, the tooling for inspecting the dimensions of large agricultural machinery castings provided by the present invention has the following beneficial effects:

[0029] Through the interaction of components such as hydraulic rod 21, clamping plate 22, casting 7, motor 1 3, threaded rod 11, threaded block 10, motor 3 20, rectangular slot 9, curved plate 4, three-coordinate measuring machine camera 15, drive assembly 6, hydraulic rod 18 and clamping plate 17, the three-coordinate measuring machine camera 15 can be controlled to scan the overall contour of the casting 7 without manual operation, thereby reducing manual workload and improving work efficiency.
