Description

Therefore, auto parts are the most important foundation of the automotive industry and a necessary factor to support the sustainable and healthy development of the automotive industry. In the actual production process of auto parts, it is necessary to detect the thickness of parts according to the actual design standards to determine whether they meet the use standards. This requires the use of auto parts thickness testing instruments to accurately test the thickness of parts.

[0003] Traditional detection devices can only perform simple thickness detection. For uneven parts, since the parts need to cooperate with other parts when installed, the multiple different surfaces of the same part need to be tested to see if the thickness meets the standard, otherwise the parts cannot be installed well. The traditional detection method requires testing one by one, which is cumbersome and has low work efficiency. At the same time, during the detection process, it is impossible to quickly classify and mark the part surfaces that exceed the standard thickness or are less than the standard thickness, and it is impossible to mark the difference based on the difference between the part thickness and the standard thickness, which is not conducive to the subsequent classification and processing of unqualified parts by operators.

[0016] The present invention has the following beneficial effects: the operator adjusts the position of the fixing frame according to the position of the surface to be inspected, and moves the adjustment block at the same time so that the measuring rod corresponds to the surface to be inspected, and then drives the mounting plate downward through the electric telescopic column. When the measuring rod contacts the surface of the part, the measuring rod moves upward under the action of the reaction force of the surface of the part until the pressure-sensing control component contacts the mounting plate, and the electric telescopic column stops extending. At this time, the amount of upward movement of the measuring rod is the actual thickness of the part. At the same time, the pressure-sensing control component sends a signal to control the drive motor and the air supply pump to start. The air supply pump supplies air to the air guide groove in the mounting block through a hose, and drives the protruding rod to extend from the movable groove under the action of the gas pressure. At the same time, the drive motor drives the transmission gear to rotate, and drives the fixed cylinder on one side to move upward and the fixed cylinder on the other side to move downward under the action of the gear rods on both sides. The fixed cylinder here is in a standard position in the initial state, and the standard position is the position where the thickness of the part is the same as the standard thickness.

[0017] When the fixed cylinder moves, it can drive the installation cylinder to move. The piston block in the installation cylinder squeezes the air inside it, and the gas in the fixed cylinder is compressed. When the arc rod on one side of the fixed cylinder contacts the raised rod, the fixed cylinder is limited and stops moving. At the same time, the arc rod can drive the movable rod to move to the side away from the raised rod. Under the action of the transmission rod, the valve rod can be driven to move downward. The valve port on the valve rod corresponds to the installation tube. At this time, the compressed gas in the installation cylinder enters the pneumatic telescopic cylinder on one side of the shunt tube through the installation tube and the telescopic tube. The pneumatic telescopic cylinder is extended to drive the material blocking rod on one side of the linkage rod to move, and the material blocking rod moves downward. The material feeding trough on the side is opened, and the material is sprayed on the surface of the part through the spray nozzle under the opened material feeding trough under the action of the spray pump. In this process, since the material boxes on both sides contain marking materials of different colors, different colors will be marked if the part is too thick or too thin during the part inspection process. At the same time, the greater the difference between the actual thickness of the part and the standard thickness, the wider the width of the mark. The operator can convert the difference between the actual thickness of the part and the standard thickness according to the mark width. If the thickness of the part is the same as the standard value, the air in the installation cylinder will not be compressed, that is, the part will not be marked;

[0018] In general, the device can quickly detect the thickness of different surfaces of parts. At the same time, it can mark different colors and widths according to the difference between the actual detected thickness and the standard value, which is convenient for operators to classify and process later. The detection efficiency is higher, the test results are more accurate and specific, which is convenient for identification and processing, and the actual use effect is better.

When the measuring rod 16 contacts the surface of the part, the measuring rod 16 moves upward under the action of the reaction force of the surface of the part until the pressure sensing control component contacts the mounting plate 9, and the electric telescopic column 3 stops extending. At this time, the amount of upward movement of the measuring rod 16 is the actual thickness of the part. At the same time, the pressure sensing control component sends a signal to control the drive motor 19 and the air supply pump 25 to start. The air supply pump 25 supplies air to the air guide groove 52 in the mounting block 51 through the hose 56.

[0042] When the fixed cylinder 22 moves, it can drive the mounting cylinder 21 to move, and the piston block 48 in the mounting cylinder 21 squeezes the air therein, and the gas in the fixed cylinder 22 is compressed. When the arc rod 27 on one side of the fixed cylinder 22 contacts the protruding rod 54, the fixed cylinder 22 is limited and stops moving.

The pneumatic telescopic cylinder 33 is extended to drive the blocking rod 59 on one side of the linkage rod 34 to move, and the feed chute 37 below the blocking rod 59 is opened. Under the action of the spray pump 31, the spray nozzle 35 below the opened feed chute 37 sprays material on the surface of the part to achieve marking of unqualified parts.

[0043] See also Figure 1-Figure 9 As another embodiment of the present invention, the pressure sensing control component includes a mounting arm 6 movably arranged on the side wall of the mounting plate 5, the bottom of the mounting arm 6 is fixedly connected to a control rod 7, and the bottom of the control rod 7 is fixedly connected to a sensor 8. In actual use, the sensor 8 triggers the control rod 7 at the moment when the measurement and detection is completed, and the control rod 7 controls the drive motor 19 and the air supply pump 25 to start working.

[0044] During the implementation of the present invention, the control lever 7 sends a signal to control the drive motor 19 and the air supply pump 25 to start. The air supply pump 25 supplies air to the air guide groove 52 in the mounting block 51 through the hose 56. Under the action of the gas pressure, the protruding rod 54 is driven to extend from the movable groove 55. At the same time, the drive motor 19 drives the transmission gear 36 to rotate. Under the action of the gear rods 24 on both sides, the fixed cylinder 22 on one side is driven to move upward, and the fixed cylinder 22 on the other side is driven to move downward. In the initial state, the fixed cylinder 22 is in the standard position, which is the position where the thickness of the part is the same as the standard thickness.

[0045] When the arc rod 27 on one side of the fixed cylinder 22 contacts the protruding rod 54, the fixed cylinder 22 is limited and stops moving. At the same time, the arc rod 27 can drive the movable rod 47 to move away from the protruding rod 54. Under the action of the transmission rod 44, the valve rod 45 can be driven to move downward. The valve port 46 on the valve rod 45 corresponds to the mounting tube 29. At this time, the compressed gas in the mounted cylinder 21 enters the pneumatic telescopic cylinder 33 on one side of the shunt tube 57 through the mounting tube 29 and the telescopic tube 39. The pneumatic telescopic cylinder 33 is extended to drive the blocking rod 59 on one side of the linkage rod 34 to move. 9, the material discharge chute 37 below is opened, and the material is sprayed onto the surface of the part through the spray nozzle 35 below the opened material discharge chute 37 under the action of the spray pump 31. In this process, since the material boxes on both sides contain marking materials of different colors, different colors of markings will be achieved during the part inspection process if the part is too thick or too thin. At the same time, the greater the difference between the actual thickness of the part and the standard thickness, the wider the width of the mark. The operator can convert the difference between the actual thickness of the part and the standard thickness according to the mark width. If the thickness of the part is the same as the standard value, the part will not be marked.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
