Technical fields:

[0001] This utility model relates to the field of hardware processing equipment, and more specifically to an automatic inspection machine for stamped parts. Background technology:

[0002] As a type of hardware, automotive stamping parts require the machining of internal threaded holes in corresponding positions. The internal threads of stamped automotive parts are generally formed by rotating an extrusion tap to form threads on the inner wall of the corresponding hole in the stamped automotive part. The unformed hole differs from the formed hole.

[0003] They need to be inspected. The current method is to manually place them under an industrial camera for inspection, then manually remove them. For qualified products, they can be placed in the qualified product stacking area; for unqualified products, they need to be manually unloaded and thrown away, which is very troublesome. Utility Model Content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic stamping parts inspection machine. It can place the automotive stamping parts to be inspected on a conveyor belt, which can automatically transport them to the bottom of an industrial camera for inspection. Unqualified parts are directly rejected, while qualified parts flow out from the right end of the inclined downward material trough. A receiving bucket can be installed at the corresponding position to directly receive the materials, which is very convenient.

The guide rods 1 are inserted into guide sleeves fixed on the inner side of the corresponding guide through holes formed on the front wall of the detection host 20, and cooperate with the guide sleeves.

[0025] Furthermore, the transverse conveying device 30 includes two corresponding side fixing plates 32, which are fixed on the top surface of the fixed base plate 10. Two transmission rollers 33 are located on the left and right sides between the two side fixing plates 32. The center of the left transmission roller 33 is fixed to the two side fixing plates 32 by means of a rotating shaft connected to the two sides by a bearing. The drive shaft fixed in the middle of the right transmission roller 33 is connected to the two side fixing plates 32 by means of a bearing. A drive servo motor 23 is fixed on the rear wall of the front wall of the housing of the detection host 20.

[0032] In this embodiment, the servo motor 23 is driven to run, causing the conveyor belt 31 to move. The automotive stamping part is placed on the left side of the upper belt of the conveyor belt 31. When it is placed, the upper belt of the conveyor belt 31 at the corresponding position is pressed down, so that the corresponding weighing sensor 5 below can sense it, indicating that a detection part has been placed. The corresponding weighing sensor 5 transmits the sensing signal to the control host. The corresponding program on the control host can calculate the time when the automotive stamping part moves to the position directly below the industrial camera 44. When the automotive stamping part moves to the position directly below the industrial camera 44, the control host controls the servo motor 23 to stop running. At this time, the lighting body 3 below it is lit. At the same time, the industrial camera 44 illuminates the screw hole of the automotive stamping part, which can determine whether its processing is in place.

[0033] When the part is qualified, the servo motor 23 is driven to run, and the stamped part of the car is finally discharged from the inclined material trough 50. For the unqualified part, the pusher of the pusher cylinder 21 is pushed to push the pusher plate 22 forward, which pushes the stamped part of the car placed on the upper belt of the corresponding conveyor belt 31 forward and pushes it out from the corresponding notch.

[0034] This embodiment has a high degree of automation and good practical effect. It can directly reject defective products and has a good effect.
