[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a fixing device for a three-dimensional coordinate measuring machine, comprising a base 1, a motor 2 is fixedly connected to one side of the outer wall of the base 1, a bidirectional screw 3 is fixedly connected to the output end of the motor 2, a clamping plate 4 is threadedly connected to the outer wall of the bidirectional screw 3, a plurality of positioning columns 5 are fixedly connected to one side of the outer wall of the clamping plate 4, a hinge seat 6 is fixedly connected to the other side of the outer wall of the clamping plate 4, a hydraulic rod 7 is rotatably connected inside the hinge seat 6, a fixing rod 8 is fixedly connected to the output end of the hydraulic rod 7, a hinge seat 2 9 is fixedly connected to the other side of the outer wall of the clamping plate 4, a fixing assembly 10 is arranged inside the hinge seat 2 9, and an organism 21 is arranged on one side of the inner wall of the clamping plate 4; the fixing assembly 10 comprises a connecting plate 1001, the outer wall of the connecting plate 1001 is rotatably connected to the inner wall of the hinge seat 2 9, and a clamping plate 2 1002 is rotatably connected to one side of the inner wall of the connecting plate 1001;
[0023] Specifically, first, the machine body 21 is placed on the upper surface of the base 1. As the support of the entire device, the base 1 needs to have sufficient strength and stability. After the machine body 21 is placed on the base 1, by starting the motor 2, the motor 2 starts to work and drives the bidirectional screw 3 to rotate. The bidirectional screw 3 is a special transmission mechanism. When it rotates, it will drive the clamping plate 4 of the outer wall to slide inside the base 1. The function of the clamping plate 4 is to perform adaptive fixation according to the size of the machine body 21. When the size of the machine body 21 is small, the clamping plate 4 will move closer to the middle and tightly clamp the machine body 21; when the size of the machine body 21 is large, the clamping plate 4 will expand outward, and it can also stably fix the machine body 21. At this time, the machine body 21 has been preliminarily fixed. In order to further enhance stability, it is necessary to start the hydraulic rod 7 to achieve further fixation. The hydraulic rod 7 is a device that uses hydraulic pressure to expand and contract. When it is started, it will push the fixing rod 8 to move. The fixing rod 8 is connected to the connecting plate 1001. When the fixing rod 8 moves, the connecting plate 1001 is driven to rotate inside the hinge seat 2 9. The other end of the connecting plate 1001 is connected to the clamping plate 2 1002. When the connecting plate 1001 rotates, the clamping plate 2 1002 is driven to be close to the outer wall of the body 21. The material of the clamping plate 2 1002 has a certain elasticity and friction, and can be closely attached to the outer wall of the body 21, thereby preventing the body 21 from shaking or deflecting during operation.
[0024] Reference Figure 1 - Figure 3 A fixing box 11 is provided on the lower surface of the base 1, and a rotating rod 12 is rotatably connected to the inner wall of the fixing box 11; the upper surface of the rotating rod 12 is fixedly connected to the lower surface of the base 1, and a worm gear 13 is fixedly connected to the outer wall of the rotating rod 12; a fixing block 14 is fixedly connected to the bottom of the inner wall of the fixing box 11, and a fixing block 2 15 is fixedly connected to the fixed block 14 away from the side; a motor 2 16 is fixedly connected to one side of the outer wall of the fixing box 11, and a transmission shaft 17 is fixedly connected to the output end of the motor 2 16, and the transmission shaft 17 is rotatably connected to the inside of the fixing block 2 15; a worm 18 is fixedly connected to one side of the outer wall of the transmission shaft 17, and the worm 18 is meshed with the worm gear 13; a left-right symmetrical mounting block 19 is fixedly connected to the outer wall of the fixing box 11, and a mounting hole 20 is opened through the mounting block 19;
[0025] Specifically, first, start the motor 2 16. The transmission shaft 17 is a key component connecting the motor 2 16 and the worm 18, and its rotation can accurately transmit power to the worm 18. As the transmission shaft 17 rotates, the worm 18 also starts to rotate. The worm 18 and the worm wheel 13 are a pair of precisely designed gears, and the meshing rotation between them can transmit power from the worm 18 to the worm wheel 13. This design not only ensures the smoothness of power transmission, but also makes the entire adjustment process smoother and more precise through the deceleration and torque-increasing effect of the worm 18 and the worm wheel 13. As the worm wheel 13 rotates, the fixed box 11 fixed on the upper surface of the rotating rod 12 also starts to rotate. The fixed box 11 is a key part of the entire adjustment mechanism. It is connected to the body 21, and the angle adjustment of the body 21 can be achieved through its rotation. The design of the fixed box 11 takes into account stability and durability to ensure that stable performance can be maintained during long-term use.
[0026] Working principle: when it is necessary to use a fixing device to fix the three-dimensional coordinate measuring machine, the machine body 21 is placed on the upper surface of the base 1. At this time, by starting the motor 2, the motor 2 drives the clamping plate 4 on the outer wall of the bidirectional screw 3 to slide inside the base 1. At this time, the clamping plate 4 drives the positioning column 5 to be fixed according to the different sizes of the machine body 21, thereby achieving the effect of stabilizing the machine body 21. At this time, by starting the hydraulic rod 7, the fixing rod 8 drives the connecting plate 1001 to rotate inside the hinge seat 29. At this time, the connecting plate 1001 drives the clamping plate 2 1002 to be close to the outer wall of the machine body 21, thereby achieving the effect of further stabilizing the machine body 21.
[0027] Secondly, when it is necessary to adjust the angle of the machine body 21, the motor 2 16 is started, and the transmission shaft 17 is driven to rotate by the motor 2 16, so as to facilitate the worm 18 to engage and rotate with the worm wheel 13. At this time, the rotation of the worm wheel 13 drives the fixed box 11 on the upper surface of the rotating rod 12 to rotate. The rotation of the fixed box 11 facilitates the adjustment of the angle of the machine body 21.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
