Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, in particular to an error detection device for numerical control machining. Background Art

[0002] With the rapid development of modern manufacturing industry, especially in aerospace, automobile manufacturing, precision instruments and other fields, the accuracy of parts in these fields directly affects the operation of equipment, so the requirements for parts processing accuracy are getting higher and higher. CNC machine tools are the main equipment for modern mechanical processing. In order to further give play to the advantages of CNC machine tools, it is necessary to use relevant error detection devices to detect its machine tools and products, so as to make timely adjustments and improve the processing accuracy of parts.

[0003] An existing error detection device for CNC machining uses a direct contact method with the part, using the contact of the sensor and the measuring tool to contact the surface of the part to measure the deviation of the parameters such as the size and shape of the part, thereby determining the machining error;

[0004] For an existing error detection device for CNC machining, firstly, in the detection of some parts after heat treatment, due to the high temperature of the parts, the existing detection device may not be able to detect them directly, and it is necessary to wait for the parts to cool before measuring, which not only affects the detection efficiency, but also causes inaccurate error measurement due to the deformation of the parts during the cooling process. Secondly, the existing error detection device has certain limitations in terms of versatility. For example, although the traditional measuring tools (calipers, micrometers, etc.) in the contact detection device are simple to operate, their versatility is mainly limited to the detection of parts with simple shapes and sizes. For parts with complex shapes, such as aircraft engine blades with complex curved surfaces, these measuring tools are difficult to accurately measure their shape errors. Finally, in modern CNC machining, the shapes of parts are becoming more and more complex, including parts with deep holes, inner cavities, curved surfaces, inclined surfaces and other features. The probe is not flexible enough when adjusting the angle. The probe needs to adjust the angle manually, which is cumbersome to operate and difficult to achieve precise angle control. This increases the difficulty and error of measurement for complex curved surface parts that need to be measured at different angles. Summary of the invention

[0045] Please see attached Fig.10 , the central control system includes:

[0046] Collection module: It is used to transmit the data collected by the temperature sensing module 909 and the probe 801 to the central control system;

[0047] Analysis module: It analyzes the data collected in the central control system through the data processing unit 802;

[0048] Driving module: drives the air pump 901 through the analyzed information.

[0049] Working principle: Place the part or object to be inspected in the middle of the placement table 1, then the hydraulic push rod 601 pushes the installation shaft 602 downward, the probe 801 approaches the inspection object, and the temperature sensing module 909 senses the temperature of the inspection object. The temperature sensing module 909 transmits the collected data to the central control system. Through the analysis of the data processing unit 802, when the cooling condition is reached, the air pump 901 is started, and the air pump 901 draws air through the air intake pipe 902 and the air intake hopper 904. The filter on the air intake hopper 904 intercepts impurities in the air. The air is pressurized by the air pump 901 and transported to the air delivery pipe 903, and then sprayed out by the nozzle 907 on the air delivery pipe 903 to cool the inspection object. After the object is cooled, the probe 801 inspects the object. The probe 801 is driven to move in the front-rear direction through the guide rail 501 and the sliding table 502, and the rotating motor 702 drives the outer gear 703 to rotate. Through the meshing relationship between the outer gear 703 and the inner gear 704, the mounting table 701 can be rotated, and the probe 801 can also be rotated. Then the adjustment motor 706 in the power cabin 705 is started, which can rotate the active bevel gear 707. Due to the meshing relationship between the active bevel gear 707 and the driven bevel gear 708, the driven bevel gear 708 and the first rotating shaft 710 rotate on the rotating block 709. When rotating, the tilt angle of the probe 801 also changes, so that data at different positions can be captured. The captured data is processed by the data processing unit 802, and the central control system is controlled through the wire 8 03 is transmitted to the display 804, so that the operator can clearly understand the error of the detected object and the reason for the error. When detecting smaller objects, such as shafts and gears, the hidden motor 1010 is started, and the hidden motor 1010 rotates the second rotating shaft 1007, and the driving gear 1004 and the worm 1009 on the second rotating shaft 1007 rotate at the same frequency. Through the meshing relationship between the worm 1009 and the worm wheel 1008 and between the driving gear 1004 and the first rack 1003, the first rack 1003 drives the baffle 1002 to be retracted into the placement table 1, and no longer blocks the hidden groove 1001. The rotating worm wheel 1008 causes the meshing second rack 1005 to move up, and the second rack 1005 drives the lifting frame when moving up. 1006 and the fixed table 1101 move up, the fixed table 1101 moves to a position flush with the placement table 1 and stops, and then the clamping block 1103 slidably connected to the fixed table 1101 is moved. At this time, the clamping spring 1102 is stretched, and then the clamping plate 1106 is opened, and a smaller test object is placed therein. The clamping plate 1106 recovers under the elastic action of the coil spring 1105, and the elastic potential energy released by the clamping spring 1102 fixes the object, and then the detection process is repeated. When the back side needs to be detected, the flipping motor 1203 is started, driving the active roller 1202 to rotate, and the driven roller 1201 also rotates under the connection of the belt 1204. The rotating driven roller 1201 causes the rotating member 1104 to rotate, thereby turning the clamped object over.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
