Common calibration devices for automobile parts include three-dimensional measuring machines, surface roughness testers and hardness testers. Among them, the three-dimensional measuring machine can complete the three-dimensional measurement, geometric shape detection, dimension measurement and position measurement of the workpiece. In general, the main function of the three-dimensional measuring machine is to perform high-precision three-dimensional measurement, analysis and detection of the geometric shape and size of the workpiece to ensure that the quality and accuracy of the workpiece meet the requirements. By comparing the measured data with the design data, the calibration of automobile parts is completed.

[0003] A three-dimensional coordinate measuring machine generally includes a main structure, a control system, a measuring probe, a workpiece fixture, and a computer system, among which the measuring probe is a key component used to contact and measure the workpiece. The measuring probe needs to ensure that the surface is clean. If there is dust or foreign matter on the surface, it may affect the contact quality between the probe and the workpiece surface, thereby causing measurement errors or unstable measurement results. In the prior art, the surface of the probe is generally wiped manually with cotton cloth to ensure the cleanliness of the probe, but this method is more troublesome and cannot prevent the surface of the probe from being contaminated with dust when it is not in use. Therefore, a calibration device for automotive parts is proposed. Utility Model Content

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0024] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0025] Example 1, please refer to Figure 1 to Figure 4 In the structure shown, in the embodiment of the utility model, a proofreading device for automobile parts comprises a workbench 1, a measuring assembly 2 and a placing table 4 arranged on the workbench 1, the measuring assembly 2 comprises a detection head 3 for measuring a workpiece, and a cleaning assembly 5 is arranged on the placing table 4;

[0026] The cleaning assembly 5 includes an air pump 1 53, an air pump 2 54 and a cleaning tube 55. An airbag ring is arranged in the cleaning tube 55. The airbag ring includes an airbag ring 59. The air pump 1 53 is used to inject gas into the airbag ring 59 or extract the gas in the airbag ring 59 to change the size of the airbag ring 59. The cleaning assembly 5 also includes a cleaning ring 512 and an elastic member 510. The elastic member 510 is used to connect the cleaning ring 512 and the airbag ring 59 to form a closed space 511 therebetween. A filler is arranged in the closed space 511. The airbag ring 59 is used to change the shape of the cleaning ring 512 so that it contacts the detection head 3.

[0027] In this embodiment, the detection head 3 is arranged on the placement table 4, and the workpiece to be measured is fixed on the placement table 4, waiting for the measurement component 2 to control the detection head 3 to detect it, and the detected data is input into the computer system, and the measured data is compared with the design data through the computer system to complete the proofreading of the workpiece. The workbench 1, the measurement component 2, the detection head 3 and the placement table 4 are all prior arts, and their structures and functions are no longer repeated. When cleaning the detection head 3, the measurement component 2 controls the detection head 3 to move in the space, and finally the detection head 3 is inserted into the cleaning tube 55 to wait for cleaning.

[0028] Furthermore, the cleaning component 5 also includes a jet nozzle 56. The air outlet of the air pump 54 is connected to the air inlet of the jet nozzle 56. The jet nozzle 56 is arranged on the cleaning tube 55. The air outlet end of the jet nozzle 56 passes through the side wall of the cleaning tube 55 and extends into the interior of the cleaning tube 55 for cleaning the outer surface of the detection head 3.

[0029] In this embodiment, the jet nozzle 56 is connected to the air pump 2 54 through the air pipe 515. The air pump 2 54 inputs gas into the interior of the jet nozzle 56 through the air pipe 515. The jet nozzle 56 sprays gas toward the detection head 3 inserted into the cleaning tube 55, and the dust on the surface of the detection head 3 is blown away by the sprayed gas.

[0030] Furthermore, the cleaning assembly 5 also includes a placing table 51 and a placing rack 52 , the placing rack 52 and the cleaning cylinder 55 are arranged on the upper end surface of the placing table 51 , and the air pump 1 53 and the air pump 2 54 are arranged on the placing rack 52 .

[0031] In this embodiment, the placement table 51 is arranged in a non-detection area on the placement table 4 to prevent obstruction of the movement of the detection head 3 when detecting the workpiece. The placement rack 52 is divided into two placement areas by a partition. The air pump 1 53 and the air pump 2 54 are placed in one placement area respectively, which can prevent the air pipe 515 from being entangled.

[0032] Furthermore, a placement groove is provided inside the cleaning tube 55, and the airbag ring further includes a mounting ring 513, which is embedded in the placement groove.

[0033] Furthermore, the outer side of the airbag ring 59 is embedded in the mounting ring 513 , and the air outlet of the air pump 53 is connected to the air inlet of the airbag ring 59 .

[0034] In this embodiment, the placement groove is circular, and its height is greater than the height of the mounting ring 513. The mounting ring 513 can be removably installed in the placement groove by means of screw connection. A mounting groove opposite to the airbag ring 59 is provided on the mounting ring 513. The outer side of the airbag ring 59 can be removably installed in the mounting groove by means of screw connection. When the airbag ring 59 is in an uninflated state, the outer surface of the outer side of the airbag ring 59 contacts the mounting groove. The air intake part of the airbag ring 59 is arranged on its outer side. The air intake part can adopt an air intake valve 58. A through hole opposite to the air intake valve 58 is provided on the mounting ring 513 and the cleaning cylinder 55. The air pump 53 and the airbag ring 59 are also connected through an air pipe 515. The air outlet end of the air pipe 515 is connected to the air intake valve 58 through the through hole.

[0035] Furthermore, two sides of the elastic member 510 are detachably connected to the airbag ring 59 and the cleaning ring 512 respectively.

[0036] In this embodiment, the elastic member 510 can be made of elastic cloth, and the cleaning circle 512 can be made of cotton cloth strips with connected ends. The elastic cloth is connected to the cleaning circle 512 and the airbag ring 59 along the outer periphery of the cleaning circle 512 and the inner periphery of the airbag ring 59, forming a closed space 511 between the airbag ring 59 and the cleaning circle 512. The filler inside the closed space 511 can be cotton. After the airbag ring 59 is inflated, the airbag ring 59 becomes larger, and the enlarged airbag ring 59 will squeeze the cotton, thereby squeezing the cleaning circle 512 to deform, and its periphery will move into the cleaning groove 57. When the detection head 3 passes through the cleaning circle 512, the cleaning circle 512 will gently wrap the detection head 3 to clean the surface of the detection head 3. The reason why the shape of the cleaning circle 512 needs to be changed is to prevent the detection head 3 from entering the cleaning groove 57 multiple times, which will cause the cleaning circle 512 that can originally wrap it to spread outward and cause the two to lose contact.

[0037] Furthermore, a cleaning groove 57 is provided in the cleaning cylinder 55 , and the cleaning ring 512 is located in the middle of the cleaning groove 57 .

[0038] Furthermore, a blowing chamber 514 is provided in the cleaning cylinder 55 . The blowing chamber 514 is provided below the cleaning groove 57 . The air outlet end of the air jet nozzle 56 is located inside the blowing chamber 514 .

[0039] Furthermore, the calibration device also includes a controller 6 , and the measuring component 2 and the cleaning component 5 are both control-connected to the controller 6 .

[0040] In this embodiment, the controller 6 controls the measuring component 2 to drive the detection head 3 to move, and the detection head 3 passes through the cleaning slot 57 until it moves into the blowing chamber 514, and then starts the air pump 2 54 to supply air to the jet nozzle 56, and the jet nozzle 56 blows air to the detection head 3 located in the blowing chamber 514 to blow away the dust attached to the surface of the detection head 3. After the dust is blown away, the air pump 2 54 is turned off, and the air pump 1 53 is started to supply gas to the air bag ring 59, so that the air bag ring 59 increases, and the increased air bag ring 59 squeezes the filler, and the cleaning ring is squeezed by the moving filler. 512, squeeze the cleaning ring 512 toward the central axis of the cleaning groove 57, and pull the detection head 3 upward. When the detection head 3 passes through the cleaning ring 512, the cleaning ring 512 contacts the surface of the detection head 3 and wipes its surface to further clean the surface of the detection head 3. The above operation can be performed to clean the detection head 3 before or after detecting the workpiece to be detected. After the detection is completed and the detection head 3 is cleaned, the detection head 3 can be inserted into the cleaning tube 55 and not pulled out, so as to prevent the detection head 3 from being contaminated with dust when it is not in working state.
