[0002] The product requires pressing during assembly, and its surface has many holes and slots for installation. Each hole and slot needs to hold a needle shaft. Since manual feeding is very slow and prone to incomplete pressing.

[0003] Furthermore, after prolonged operation, it is easy for needle shafts to be missed in many holes and slots. Once a missed needle shaft is found, it is difficult to locate it accurately, leading to defective products. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a pressing quality inspection device, which overcomes the shortcomings of the existing technology and effectively solves the problems of slow pressing efficiency, incomplete pressing and easy leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A press-fitting quality inspection device includes an inspection table. A horizontal push cylinder is provided on one side of the inspection table, and a connecting frame is fixedly connected to the piston rod of the horizontal push cylinder. A staggered cylinder is fixedly connected to the inner walls of both sides of the connecting frame, and a blowpipe is fixedly connected to the piston rod of the staggered cylinder. A downward pressing cylinder is fixedly connected to the top outer wall of the connecting frame, and a pressure plate is fixedly connected to the piston rod of the downward pressing cylinder. A positioning pin is welded to the bottom outer wall of the pressure plate.

[0007] The top of the testing platform is equipped with a lifting cylinder, and the piston rod of the lifting cylinder is fixedly connected to a lifting plate. A height detection shaft is slidably connected to the inner wall of the lifting plate. Fixing plates are welded to the outer walls on both sides of the lifting plate, and through-beam sensors are installed on the inner walls of the fixing plates.

[0008] Preferably, a crossbeam is welded to one side of the outer wall of the testing platform, and a horizontal push cylinder is fixedly connected to the outer wall of the crossbeam.

[0009] Preferably, a vertical frame is welded to the top outer wall of the testing platform, and a lifting cylinder is fixedly connected to the top outer wall of the vertical frame.

[0010] Preferably, the inner wall of one side of the vertical frame is fixedly connected with symmetrically distributed vertical rails, and the lifting plate is slidably connected to the outer wall of the vertical rails.

[0011] Preferably, the product is placed on the outer wall of the top of the testing platform, and a needle shaft is placed on the inner wall of the product.

[0012] Preferably, the outer walls of the testing platform are screwed with lead screws on three sides, and a positioning block is rotatably connected to one end of the lead screw, with the positioning block tightly attached to the outer wall of the product.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The press-fitting quality inspection equipment designed in this paper uses a staggered cylinder to drive the blow-nail tube to move. The blow-nail tube can blow the nail into place and press the needle shaft into the pressing position. In addition, the downward pressing cylinder drives the pressure plate to move downward, which can control the positioning pin to press the needle shaft, thereby controlling the product to complete the needle threading. This realizes the automatic feeding of the needle shaft, saves manpower, and ensures that the needle shaft is pressed in place.

[0015] 2. The press-fitting quality inspection equipment designed in this way uses the action of the lifting cylinder to push down the lifting plate, so that the height detection shaft can contact the needle shaft of the product. The height difference of the height detection shaft is used to control whether the photoelectric sensor can shoot in the same direction, which can determine whether there is a problem of missing needle shaft on the product. It works quickly and effectively, greatly improving the product qualification rate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, refer to Figure 1-2A press-fitting quality inspection device includes an inspection table 1. A horizontal push cylinder 2 is provided on one side of the inspection table 1, and a connecting frame 3 is fixedly connected to the piston rod of the horizontal push cylinder 2. A staggered cylinder 4 is fixedly connected to the inner walls on both sides of the connecting frame 3, and a blow-nail pipe 5 is fixedly connected to the piston rod of the staggered cylinder 4. A downward pressing cylinder 6 is fixedly connected to the top outer wall of the connecting frame 3, and a pressure plate 7 is fixedly connected to the piston rod of the downward pressing cylinder 6. A positioning pin 8 is welded to the bottom outer wall of the pressure plate 7.

[0022] In this embodiment, the blow-nail tube 5 is moved by the misaligned cylinder 4, which blows the nail into place and presses the needle shaft 17 into the pressing position. The pressure plate 7 is moved downward by the pressing cylinder 6, which controls the positioning pin 8 to press the needle shaft 17, thereby controlling the product 18 to complete the needle threading. This realizes the automatic feeding of the needle shaft 17, saves manpower, and ensures that the needle shaft 17 is pressed into place.

[0023] Example 2, refer to Figure 3 A press-fitting quality inspection device, wherein a lifting cylinder 9 is provided on the top of the inspection table 1, and a lifting plate 10 is fixedly connected to the piston rod of the lifting cylinder 9. A height detection shaft 11 is slidably connected to the inner wall of the lifting plate 10. Fixing plates 12 are welded to the outer walls on both sides of the lifting plate 10, and a through-beam sensor 13 is installed on the inner wall of the fixing plate 12.

[0024] In this embodiment, the lifting plate 10 is pushed down by the lifting cylinder 9, and the height detection shaft 11 can contact the needle shaft 17 of the product 18. The height difference of the height detection shaft 11 is used to control whether the photoelectric sensor 13 can shoot, which can determine whether there is a problem of missing needle shaft 17 on the product 18. It is fast and effective, and greatly improves the pass rate of the product 18.

[0025] Reference Figure 2 A crossbeam 14 is welded to one side of the outer wall of the testing platform 1, and the horizontal push cylinder 2 is fixedly connected to the outer wall of the crossbeam 14.

[0026] Reference Figure 1 The top outer wall of the testing platform 1 is welded with a vertical frame 15, and the lifting cylinder 9 is fixedly connected to the top outer wall of the vertical frame 15.

[0027] Reference Figure 1 and Figure 3 The inner wall of one side of the vertical frame 15 is fixedly connected with symmetrically distributed vertical rails 16, and the lifting plate 10 is slidably connected to the outer wall of the vertical rails 16.

[0028] Reference Figure 2 The product 18 is placed on the outer wall of the top of the testing table 1, and the needle shaft 17 is placed on the inner wall of the product 18.

[0029] Reference Figure 2The outer walls of the testing platform 1 are all screwed with lead screws 19, and one end of the lead screw 19 is rotatably connected to a positioning block 20, which is in close contact with the outer wall of the product 18.

[0030] Working principle: First, the flat-push cylinder 2 pushes the connecting frame 3 to move, controlling the pressure plate 7 to move directly above the product 18. Then, the staggered cylinder 4 drives the blow nail tube 5 to move, and the blow nail tube 5 can blow the nail into place to blow the needle shaft 17 into the pressing position. Furthermore, the downward pressing cylinder 6 drives the pressure plate 7 to move downward, which can control the positioning pin 8 to press the needle shaft 17, thereby completing the needle threading operation of the product 18.

[0031] Afterwards, the horizontal cylinder 2 resets, and the lifting cylinder 9 pushes the lifting plate 10 downward, so that the height detection shaft 11 can contact the needle shaft 17 of the product 18. If there is a problem of missing needle shaft 17, the height of the height detection shaft 11 will be very low, and the through-beam sensor 13 will be able to shoot. Conversely, the through-beam sensor 13 will not be able to shoot. Therefore, by using the height difference of the height detection shaft 11 to control whether the through-beam sensor 13 can shoot, it is possible to determine whether there is a problem of missing needle shaft 17 on the product 18.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
