Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing part quality inspection, and specifically to a quality inspection method and device for a digital prototype. Background Art

[0002] In modern manufacturing, as the complexity of mechanical processing equipment and parts continues to increase, such as aerospace equipment, automotive processing equipment, machine tool processing equipment, etc., it contains many subsystems and parts. Traditional physical inspection methods are time-consuming and labor-intensive, and digital prototype technology enables the construction of an overall model of the equipment in a virtual environment. Quality inspection through digital prototypes can discover design defects in advance and avoid the high cost of discovering problems after the physical prototype is manufactured. Therefore, we need a quality inspection method and equipment equipped with digital prototypes.

[0003] However, the quality inspection method and equipment currently used, which are equipped with digital prototypes, cannot perform rapid batch size inspection on processed parts, cannot perform automatic rebound, cannot quickly fix processed parts, and cannot scan and inspect the surface quality of the inner wall of tubular processed parts. Summary of the invention

[0004] The purpose of the present invention is to provide a quality inspection method and device for a digital prototype to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The cam is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, and the camshafts are provided with a plurality of camshafts, each of which is provided with a plurality of camshafts.

[0007] Preferably, the slide groove is symmetrically arranged with the central axis of the base as the center, and the slide rod is slidably connected to the push plate.

[0008] Preferably, the limiting push rod forms a telescopic structure with the push plate through a limiting spring, and the limiting push rod is snap-connected with the base.

[0009] Preferably, the positioning rods form a telescopic structure with the fixed disk through positioning springs, and the positioning rods are distributed in a ring array with the central axis of the fixed disk as the center.

[0010] Preferably, the top plate is movably connected to the detection sleeve, and the inner wall of the detection sleeve is of open-hole design.

[0011] Preferably, the limit shaft is symmetrically arranged with the central axis of the detection sleeve as the center, and the pointer fits tightly with the scale line.

[0012] A quality inspection method and device for a digital prototype of an equipment, comprising the following steps:

[0013] S1, press the positioning rod inward, and then sleeve the tubular workpiece with the fixed plate, and the positioning rod is pushed out by the elastic force of the positioning spring, so that the positioning rod is engaged and fixed with the through hole set in the side wall of the tubular workpiece, which is convenient for quick disassembly and assembly of the tubular workpiece;

[0014] S2. Push the push-pull handle inward to drive the push plate to slide horizontally along the slide rod, push the tubular workpiece into the interior of the detection sleeve, and when the push plate and the detection sleeve are tightly fitted, the limit push rod is pushed downward by the elastic force of the limit spring to be engaged and fixed with the through hole set on the outer wall of the base, so as to avoid shaking of the tubular workpiece during scanning and detection, thereby improving the accuracy of the detection data;

[0015] S3. When the tubular workpiece is pushed inward, the top plate moves accordingly, and the pointer slides to the specified position. By observing the scale line pointed by the pointer, the length of the tubular workpiece is quickly measured, and unqualified tubular workpieces are removed. At the same time, the inner wall surface quality of the tubular workpiece is scanned and tested by the digital prototype detection probe to avoid the occurrence of notches, scratches, unevenness and other products that affect product quality, and the signal is uploaded to the screen for detection through the signal transmitter to avoid errors;

[0016] S4. When the inspection of the tubular workpiece is completed, the limit push rod is pulled upward to release the engagement state between the limit push rod and the base. At this time, the return spring pushes the tubular workpiece to automatically pop out through its own elastic force, making it convenient to replace a new tubular workpiece for inspection;

[0017] S5. Finally, the positioning rod is pressed to remove the inspected tubular workpiece and replace it with a new tubular workpiece to continue the inspection, thereby completing the quality inspection operation of the tubular workpiece.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The slide groove, slide bar, push plate, push-pull handle, limit spring and limit push rod are set. The push plate is pushed to slide horizontally along the slide bar. After the push plate is pushed to the specified position, the limit push rod is pushed out by the elastic force of the limit spring, so that the limit push rod is engaged and fixed with the base. The setting of the limit push rod avoids shaking during the measurement of the tubular workpiece, which affects the detection data.

[0020] 2. The fixed plate, positioning spring, positioning rod and digital prototype detection probe are set. The positioning rod is pressed and then the tubular workpiece is sleeved with the fixed plate. The positioning rod is pushed outward by the elastic force of the positioning spring to fix the positioning rod and the tubular workpiece. The coordinated use of the positioning spring and the positioning rod facilitates the rapid disassembly and assembly of the tubular workpiece, improves the detection efficiency, and adapts to batch detection operations. At the same time, the setting of the digital prototype detection probe scans and detects the surface quality of the inner wall of the tubular workpiece, and projects the scanning results onto the display screen through the signal transmitter for observation and comparison. Compared with naked eye detection, it has higher accuracy and smaller error.

[0021] 3. The detection sleeve, top plate, limit shaft, pointer, reset spring, scale line and signal transmitter are set. When the push plate drives the tubular workpiece to slide into the detection sleeve to the specified position, the tubular workpiece pushes the top plate to move inward. At the same time, the pointer points to the scale line as the top plate moves, so as to quickly measure the length of the tubular workpiece and quickly eliminate unqualified products. Compared with manual measurement using a ruler, it is more efficient. At the same time, when the detection is completed, the reset spring will eject the tubular workpiece through its own elastic force, which is convenient for replacing the tubular workpiece and improving the convenience of tubular workpiece detection.
