Description

Technical Field

[0001] The invention relates to the technical field of motor housing detection, in particular to a computer-aided comprehensive detection tool and a detection method. Background Art

[0002] The motor housing rear box comprehensive inspection fixture is a special inspection equipment specially used to measure and evaluate the size, shape, position characteristics and quality of the motor housing rear box. The motor housing rear box comprehensive inspection fixture is mainly used to realize the online inspection of the motor housing rear box. The surface and periphery of the motor housing rear box are inspected by visual inspection, measuring table, caliper and other tools. The holes of different properties on the motor housing rear box and the connection positions with other parts are visually inspected by inspection pins or visual inspection. In addition, for some extremely important functional dimensions on the motor housing rear box, the inspection fixture can also be used for numerical inspection.

[0003] In the previous quality system, there were some functional gauges. These data could not be sampled before. These test results were basically judged manually on the spot or recorded on paper, and could not be digitized. These gauges were mainly concentrated in go / no-go gauges, thread gauges, thread depth gauges, finger depth gauges, and plunger position gauges. However, as the current quality data requirements are getting higher and higher, many customers will also have the need to digitize these gauges for quality data control and traceability. Because the number of functional gauges in a single workstation is large, and there are many steps in the detection position, the operator may forget whether a certain gauge has been used or whether a certain detection position has been completed. After the detection is completed, it is difficult to remember all the gauges and the measurement results of all steps, and there is a risk of loss of control.

[0004] Therefore, we propose a computer-aided comprehensive inspection tool and detection method. Summary of the invention

[0005] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a computer-aided comprehensive inspection fixture and inspection method, so that the corresponding gauge is selected through the corresponding indicator light, which can avoid measurement errors caused by selecting the wrong gauge. A plurality of position template holes are set on the inspection frame, and the holes of the workpiece are visualized through the position template holes to prevent missed inspections. The inspection data is automatically recorded by controlling the computer for easy query.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A computer-aided comprehensive inspection tool, characterized in that it comprises:

[0008] A detection frame is provided with a plurality of position template holes;

[0009] The gauge assembly includes a gauge rack, on which a plurality of gauges are arranged, and each gauge is provided with a corresponding indicator light;

[0010] Control computer, used to control indicator lights and guide gauges to be inserted into corresponding position template holes;

[0011] Among them, a trigger switch is set on the position template hole. When not detecting, the trigger switch and the detection frame are not connected. After the gauge is inserted to the bottom of the corresponding position template hole, the gauge squeezes the trigger switch, so that the trigger switch and the detection frame are connected to transmit the signal to the control computer, indicating that the detection is qualified; if the gauge cannot be inserted to the bottom of the corresponding position template hole, the detection fails.

[0012] The detection frame is arranged on the bracket, and a first track is arranged on a side of the top of the bracket away from the detection frame.

[0013] The top of the bracket is also provided with a lifting plate, which is arranged in the detection frame and can be lifted and lowered relative to the bracket, and a second track is arranged on the lifting plate.

[0014] It also includes a trolley for transporting the workpiece into the detection frame; the trolley includes a lifting frame, a third track is arranged on the top of the lifting frame, and a placement plate that can move along the third track is arranged on the top of the third track.

[0015] The bracket is provided with positioning pins, and the placement plate is positioned by the positioning pins after the lifting plate is lowered.

[0016] The height of the third track is the same as that of the first track, and after the lifting plate is raised, the height of the second track is the same as that of the first track.

[0017] The first track, the second track and the third track have the same structure and spacing.

[0018] The trigger switch includes a spring sheet, and when not detecting, the spring sheet and the detection frame are not connected. After the gauge is inserted to the bottom, the gauge squeezes the spring sheet, so that the spring sheet and the detection frame are connected.

[0019] The control computer is provided with a display screen, which can display the detection frame and the position template hole. The display screen can display a guide light. The guide light of the display screen flashes at the position template hole to be tested. A green light is displayed for the position template hole that passes the test, and a red light is displayed for the position template hole that fails the test.

[0020] The present invention also discloses a method for detecting a rear housing of a motor housing, comprising the following steps:

[0021] Place the workpiece to be tested on the placement plate, and use the trolley to transport the workpiece to the vicinity of the bracket;

[0022] Move the trolley so that the third track of the trolley is aligned with the first track of the bracket, lift the lifting plate so that the second track is aligned with the first track, and push the placement plate and the workpiece to be measured onto the second track;

[0023] The lifting plate descends, and the placement plate and the workpiece to be tested are positioned by the positioning pins on the bracket; then the detection begins;

[0024] Select the gauge with the indicator light on, and insert the gauge into the corresponding position template hole for detection according to the guidance of the control computer. If the gauge is inserted to the bottom, the gauge squeezes the trigger switch, so that the trigger switch and the detection frame are connected to transmit the signal to the control computer, and the control computer displays a green light on the position template hole on the display screen, indicating that the detection is qualified; if the gauge is not inserted to the bottom, the gauge does not squeeze the trigger switch, and the control computer displays a red light on the position template hole on the display screen, indicating that the detection is unqualified;

[0025] After testing a gauge, put the gauge back on the gauge rack, take another gauge with a lighted indicator, and test it according to the guidance of the control computer until all the gauges are tested. The control computer records the test data.

[0026] The lifting plate rises, moves the placement plate and the workpiece to the third track, and the moving trolley removes the workpiece.

[0027] The beneficial effects of the present invention are as follows:

[0028] The invention has a compact and reasonable structure and is easy to operate. The corresponding gauge is selected through the corresponding indicator light to avoid measurement errors caused by wrong gauge selection. A plurality of position template holes are arranged on the detection frame. The holes of the workpiece are visualized through the position template holes to prevent missed detection. The detection data is automatically recorded by controlling the computer for easy query.

[0029] At the same time, the present invention also has the following advantages:

[0030] (1) A spring is provided on the position template hole. When not testing, the spring is not connected to the detection frame. After the gauge is inserted to the bottom, the gauge squeezes the spring so that the spring is connected to the detection frame, and then transmits the signal that the gauge is inserted to the bottom to the control computer.
