Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0033] A three-coordinate measuring machine capable of measuring irregular objects, including a base 1 and a three-coordinate measuring instrument 2 provided on the base 1. A turntable 3 is rotatably provided on the base 1, and a placement plate 4 is provided above the turntable 3. A rotating member 5 for driving the turntable 3 and the placement plate 4 to rotate is provided in the base 1. An adjusting member 6 for driving the placement plate 4 to deflect is provided on the turntable 3 and the placement plate 4. The adjusting member 6 includes a support rod 51 fixedly installed in the middle of the turntable 3, an electric push rod 52 and an electric push rod 53 fixedly installed on the turntable 3, and universal balls 54 respectively provided at the top end of the support rod 51, the output shaft ends of the electric push rod 52 and the electric push rod 53. The support rod 51 is connected to the middle of the placement plate 4 through the universal ball 54. The output shaft ends of the electric push rod 52 and the electric push rod 53 are respectively connected to one side of the bottom surface of the placement plate 4 through the universal ball 54. The rotating member 5 includes a motor 61 fixedly installed in the base 1, a driving wheel 62 and a driven wheel 63 rotatably provided in the base 1, and a belt 64 sleeved on the driving wheel 62 and the driven wheel 63. The output shaft end of the motor 61 is fixedly installed with the middle of the driving wheel 62. The bottom surface of the turntable 3 is fixedly installed with the top surface of the driven wheel 63. The belt 64 is respectively in transmission connection with the driving wheel 62 and the driven wheel 63.

[0034] During use, the operator places the irregular object on the placement plate 4 and starts the three-coordinate measuring instrument 2 to measure the irregular object;

[0035] Start the motor 61 in the base 1. Its output shaft drives the driving wheel 62 to rotate. Through the transmission of the belt 64, the driven wheel 63 rotates accordingly. Since the bottom surface of the turntable 3 is fixedly installed with the top surface of the driven wheel 63, the turntable 3 rotates accordingly. The turntable 3 drives the placement plate 4 and the irregular object to rotate, and can adjust the measurement orientation of the irregular object.

[0036] The electric push rod one 52 and the electric push rod two 53 on the turntable 3 work, and their output shafts extend and retract. Through the connection of the universal balls 54 with the placement plate 4, the placement plate 4 is pushed to deflect. The universal balls 54 at the top of the support rod 51 play a role in supporting and assisting the deflection of the placement plate 4. In this way, the measurement angle of the irregular object placed on the placement plate 4 can be adjusted;

[0037] This three - coordinate measuring machine can adjust the orientation and angle of the object to be measured, facilitating the measurement of irregular objects from multiple angles, thereby completely obtaining the three - dimensional data of the irregular object. Especially for objects with complex curved surfaces, it can reduce the measurement dead angle and improve the measurement accuracy and integrity.

[0038] Symmetric fixing plates 7 are arranged on the placement plate 4. A driving member 8 for driving the fixing plates 7 to move horizontally closer to and away from each other is arranged on the placement plate 4. The driving member 8 includes symmetric slideways 81 opened on the placement plate 4, a bidirectional lead screw 82 rotatably arranged in the slideways 81, and a knob 83 fixedly installed at one end of the bidirectional lead screw 82. The two groups of fixing plates 7 are respectively slidably arranged on the slideways 81, and the two groups of fixing plates 7 are respectively threadedly connected to the bidirectional lead screw 82;

[0039] When it is necessary to clamp and fix the item to be measured, the operator rotates the knob 83, and the bidirectional lead screw 82 rotates in the slideways 81. Since the two groups of fixing plates 7 are respectively threadedly connected to the bidirectional lead screw 82 and slidably arranged on the slideways 81, as the bidirectional lead screw 82 rotates, the two groups of fixing plates 7 move horizontally on the slideways 81, getting closer to or away from each other, thereby realizing the clamping or loosening of the item to be measured, and being able to clamp and fix the item to be measured, effectively improving the measurement stability.

[0040] Anti - slip patterns are arranged on the top surface of the placement plate 4 and the side surfaces of the fixing plates 7;

[0041] The anti - slip patterns arranged on the top surface of the placement plate 4 and the side surfaces of the fixing plates 7 can increase the friction force with the object to be detected, effectively preventing the object from sliding when clamping and placing the object, and further improving the stability during the measurement process.

[0042] A controller is arranged on the base 1. The controller is electrically connected to the three - coordinate measuring instrument 2, the electric push rod one 52, the electric push rod two 53, and the motor 61 respectively;

[0043] The controller on the base 1 is electrically connected to the coordinate measuring instrument 2, the first electric push rod 52, the second electric push rod 53, and the motor 61 respectively. Through the controller, the start and stop of the motor 61 can be controlled, so as to control the rotation of the turntable 3, the telescoping of the first electric push rod 52 and the second electric push rod 53 can be controlled, the angle of the placement plate 4 can be adjusted, and the coordinate measuring instrument 2 can also be controlled to perform measurement work, realizing the automation and precise control of the entire measurement process.

[0044] Working principle:

[0045] During use, the operator places the irregular object on the placement plate 4 and starts the coordinate measuring instrument 2 to measure the irregular object;

[0046] The motor 61 inside the base 1 is started, and its output shaft drives the driving wheel 62 to rotate. Through the transmission of the belt 64, the driven wheel 63 rotates accordingly. Since the bottom surface of the turntable 3 is fixedly installed with the top surface of the driven wheel 63, the turntable 3 rotates accordingly, and the turntable 3 drives the placement plate 4 and the irregular object to rotate, enabling the adjustment of the measurement orientation of the irregular object;

[0047] The first electric push rod 52 and the second electric push rod 53 on the turntable 3 work, and their output shafts telescope. Through the connection with the placement plate 4 by the universal balls 54, the placement plate 4 is pushed to deflect. The universal balls 54 at the top of the support rod 51 play a role in supporting and assisting the deflection of the placement plate 4. In this way, the measurement angle of the irregular object placed on the placement plate 4 is adjusted;

[0048] When it is necessary to clamp and fix the item to be measured, the operator rotates the knob 83, and the bidirectional lead screw 82 rotates in the slideway 81. Since the two groups of fixing plates 7 are respectively threadedly connected to the bidirectional lead screw 82 and are slidably arranged on the slideway 81, as the bidirectional lead screw 82 rotates, the two groups of fixing plates 7 move horizontally on the slideway 81, approaching or separating from each other, thereby realizing the clamping or loosening of the item to be measured, being able to clamp and fix the item to be measured, and effectively improving the measurement stability;

[0049] The anti-slip patterns provided on the top surface of the placement plate 4 and the side surfaces of the fixing plates 7 can increase the friction with the object to be detected, effectively preventing the object from sliding when clamping and placing the object, and further improving the stability during the measurement process;

[0050] The controller on the base 1 is electrically connected to the coordinate measuring instrument 2, the first electric push rod 52, the second electric push rod 53, and the motor 61 respectively. Through the controller, the start and stop of the motor 61 can be controlled, so as to control the rotation of the turntable 3, the telescoping of the first electric push rod 52 and the second electric push rod 53 can be controlled, the angle of the placement plate 4 can be adjusted, and the coordinate measuring instrument 2 can also be controlled to perform measurement work, realizing the automation and precise control of the entire measurement process;

[0051] This three-coordinate measuring machine can adjust the orientation and angle of the object to be measured, facilitating the measurement of irregular objects from multiple angles, thereby completely obtaining the three-dimensional data of the irregular objects. Especially for objects with complex curved surfaces, it can reduce the measurement dead angles and improve the measurement accuracy and integrity.

[0052] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
