Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and specifically discloses a punching detection device for automobile parts. Background Art

[0002] Sheet metal is one of the essential parts of automotive accessories. It is usually made by alloy stamping and deformation. In order to facilitate the matching or mutual fixation of sheet metal parts with other related accessories, punching of sheet metal parts is an essential processing step.

[0003] Normally, punching of sheet metal parts is done in a stamping machine, that is, using a hydraulic press or other equipment to drive the punch to move through the sheet metal to form a through hole on the sheet metal. However, due to the continuous wear of the punch during the punching process, the sheet metal may be missed or the punching accuracy may not meet the standards. Therefore, punching detection is also one of the essential processing steps for sheet metal parts.

[0004] Currently, punching detection relies on manual inspection or infrared probe detection methods. Manual inspection is labor-intensive and requires multiple handling and transfer of sheet metal parts, which is inefficient. Infrared probe detection is prone to misjudgment when foreign objects are present in the through-holes, affecting the operating efficiency of the entire production line. Therefore, in view of this, the inventor provides a punching detection device for automotive parts to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in traditional automobile parts punching detection, when there is foreign matter in the through hole, misjudgment is likely to occur, which affects the operating efficiency of the entire production line.

[0006] To achieve the above-mentioned objectives, the basic solution of the present invention provides an automobile parts punching detection device, comprising a frame, a carrier plate provided on the frame and capable of accommodating the automobile parts to be inspected, a first detection component and a second detection component provided on the frame and located above and below the carrier plate, respectively;

[0007] The first detection assembly includes a vertical drive mechanism provided on the frame, a mounting plate driven by the vertical drive mechanism, and a plurality of detection rods provided on the mounting plate;

[0008] The second detection component includes a sleeve arranged on the frame and located directly below each detection rod, a conductive ring arranged on the inner wall of the sleeve and electrically connected to the detection rod, a power supply for powering the detection rod and the conductive ring, and a microcontroller for receiving electrical signals between the detection rod and the conductive ring.

[0009] The principles and effects of this basic solution are:

[0010] The utility model determines whether the punching is normal by arranging a detection rod and a conductive ring. Even when there is a foreign object in the through hole, the vertical movement of the detection rod can push the foreign object out, thereby avoiding the problem of misjudgment due to the presence of foreign objects. Compared with traditional manual detection, the utility model is not only efficient but also has lower labor costs. Compared with traditional infrared probe detection, the utility model can also effectively solve the problem of easy misjudgment when there is a foreign object in the through hole, which affects the operating efficiency of the entire production line.

[0011] Furthermore, the detection rod includes a measuring rod and a connecting rod provided at the bottom of the measuring rod, wherein the bottom of the connecting rod is provided with a contact electrically connected to the conductive ring. Through this arrangement, it is possible to further detect whether the size of the through hole after punching meets the standard.

[0012] Furthermore, the diameter of the measuring rod decreases from top to bottom, and there are multiple conductive rings, each electrically connected to a resistor, which are connected in series. This method can further detect the size of the through hole and effectively improve the accuracy of size detection.

[0013] Furthermore, a first connecting piece is provided between each conductive ring and an adjacent resistor, and a second connecting piece is provided between each two adjacent resistors. The first connecting piece connects the resistor to the conductive ring, while the second connecting piece connects the resistors to each other. This ensures that when the contact point contacts different conductive rings, the circuit resistance in the loop differs, resulting in different currents in the loop, which in turn reflects the size of the through-hole.

[0014] Furthermore, an insulating ring is provided between adjacent conductive rings, wherein the thickness of the insulating ring is smaller than the thickness of the contact point. The insulating ring isolates adjacent conductive rings from each other, thereby facilitating contact between the contact point and different conductive rings.

[0015] Furthermore, the vertical drive mechanism includes a power member mounted on the frame, a threaded rod driven by the power member, a nut seat mounted on the mounting plate and threadably engaged with the threaded rod, and a plurality of guide rods mounted on the frame to allow the mounting plate to slide vertically. The power member drives the threaded rod to rotate, causing the nut seat to drive the mounting plate to move vertically. The guide rods act as a limiter and guide for the movement of the mounting plate during this process.

[0016] Furthermore, the top of the measuring rod is slidably connected to the mounting plate, extends beyond the mounting plate, and is provided with a bump. This arrangement allows the coupling between the measuring rod and the sleeve to rely primarily on the weight of the measuring rod itself, preventing the power of the vertical drive mechanism from affecting the normal detection process.

The first detection assembly includes a vertical drive mechanism mounted on the frame 1, a mounting plate 3 driven by the mechanism, and several detection rods mounted on the mounting plate 3. The positions of the detection rods correspond to the punching locations of the auto parts, and different auto parts should be equipped with detection rods in different positions.

The carrier plate 4 is also mounted on the guide rods 5 and fixed relative to the guide rods 5. The detection rod includes a measuring rod 6 and a connecting rod 7 mounted at the bottom of the measuring rod 6. The diameter of the measuring rod 6 decreases from top to bottom. A contact 15 is provided at the bottom of the connecting rod 7. Figure 4 As shown, the top of the measuring rod 6 is slidably connected to the mounting plate 3 and the top of the measuring rod 6 extends out of the mounting plate 3 and is provided with a protrusion.

[0027] The second detection assembly includes a base plate 8 provided at the bottom of the frame 1, a sleeve 9 provided on the base plate 8 and located directly below each detection rod, a conductive ring 10 provided on the inner wall of the sleeve 9 and electrically connected to the detection rod, a power supply for supplying power to the detection rod and the conductive ring 10, and a microcontroller for receiving electrical signals between the detection rod and the conductive ring 10.
