[0022] The upper punch fixing plate is provided with a feeding hole and a pressing hole in the middle, and the feeding hole and the pressing hole are both in communication with the upper punch; the feeding pipe is inserted into the feeding hole to send the pin to the upper punch;

[0023] The pressure rod of the upper slide plate assembly passes through the pressing hole to apply pressure to the pin.

[0024] Further, the hopper, the feeding cylinder, the punch pin, the feeding proximity switch, the feeding mechanism base;

[0025] The feeding mechanism base is connected with the lower base,

[0026] The cylinder is installed on the feeding mechanism base, and the cylinder drives the punch pin to move;

[0027] The pin is placed in the hopper, and the side wall of the hopper is provided with two coaxial first through holes and second through holes;

[0028] (1) The first through hole is connected with the feeding pipe, and the punch pin is inserted into the second through hole to push the pin into the feeding pipe. The diameter of the pin is only 1.6 mm, and the material is 0Cr18Ni9Ti, and the yield strength of the material itself is about 200~240MPa. When the force during the press fitting is greater than the plastic deformation pressure of the material itself, the pin will be deformed, and once it is deformed, it will be difficult to be pressed into the pointer frame hole. Therefore, it is necessary to ensure that the coaxiality of the pointer frame pin hole and the pin during press fitting is not greater than 0.05 mm. The device is ensured by the following two points: first, the pointer frame is positioned on the lower positioning platform with the lower positioning pin inserted into the pin hole; second, the lower positioning platform is fixed on the XY bidirectional floating sliding platform, and the coaxiality of the lower positioning pin and the upper press head hole is adjusted to within 0.02 mm through the special centering tool adjustment. Through the above method, the press fitting force borne by the pin during press fitting can be greatly reduced, so that the pin will not be plastically deformed during the press fitting process.

[0029] (2) According to the process requirements, three rivets need to be riveted on the upper and lower pin hole openings of the pointer frame after the pin is press fitted, that is, the hole opening is deformed to seal the pin in the pointer frame, so as to ensure that the pin does not fall out during the working process of the product. Because the pin hole is very small, if the product is clamped and riveted after the press fitting is completed, the pin hole of the product will be occupied by the pin at this time, and the clamped product will have no positioning reference. Therefore, the upper and lower hole openings of the pin need to be punched and riveted immediately after the pin is press fitted. The device is realized by sleeving the upper punch riveting head outside the press rod (with the press rod as the positioning center) and sleeving the lower punch riveting head outside the lower positioning pin (with the lower positioning pin as the positioning center). When the press rod completely press-fits the pin into the pointer frame, the upper and lower punch riveting heads immediately punch and rivet the upper and lower hole openings of the pin, because the product is still in the original positioning position at this time, so the coaxiality of the upper and lower punch riveting can meet the process requirements.

[0030] (3) In order to achieve the accurate positioning of the lower positioning pin to the product, the lower positioning pin must be inserted into the pointer frame pin hole for more than 2 / 3 of the pin hole length. When the positioning pin is pressed into the pin hole and moves downward, the lower positioning pin must be able to retract. This device achieves this function by fixing the lower positioning pin on a spring support. When not pressed, the lower positioning pin is kept in the upper position under the spring support. When the pin contacts the lower positioning pin and moves downward, the lower positioning pin is pressed downward by the pin to overcome the spring force and move downward.

[0031] (4) When the positioning pin is pressed into the pin hole and contacts the lower positioning pin and continues to move downward, the lower positioning pin is pressed downward synchronously until the pin is completely pressed into the pointer frame. At this time, the upper punch needs to continue to press downward to complete the press-in of the upper opening of the pointer frame pin hole. The pressing rod on this device is fixed on an elastic structure, which is fixed with the upper punch on the piston head of the servo cylinder. The elastic structure provides a deformation force greater than the pin pressing force. When the pin is pressed, the elastic structure is not compressed, and the pressing rod moves downward with the upper punch to press the pin into the pointer frame. When the pressing is completed, the upper pressing rod is blocked by the limiting stop on the positioning platform. At this time, when the upper punch continues to move downward, the resistance of the elastic structure is greater than the deformation force it can overcome, and it is compressed and deformed. On the device, the upper punch continues to move downward and the pressing rod is blocked in the vertical direction and cannot continue to press the pin downward.

[0032] (5) The upper punch only completes the press-in of the upper opening of the pin hole, and the lower punch must complete the press-in of the lower opening of the pin hole. This device fixes the entire product positioning platform on an elastic structure to achieve this action. The lower punch is fixed on the overall base, and the product positioning platform is fixed on an elastic structure. The positioning platform can move downward relative to the lower punch under the action of external force. When the device completes the press-in of the upper opening of the pin, the upper punch fixing member contacts the limiting stop on the positioning platform. At this time, under the action of the cylinder, the upper punch continues to move downward, overcoming the spring force of the positioning platform elastic structure, so that the positioning platform moves downward together with the workpiece, and the lower punch is fixed. Therefore, the press-in of the lower opening of the pin hole is completed.

[0033] (6) The device is provided with a weighing sensor between the upper punch and the electric cylinder, which monitors the press fitting process of the pin and the press riveting of the orifice through the force change in the press fitting process. If the pressure exceeds 100KG during the press pin process, the device will alarm and stop the press fitting, indicating that the interference amount of the pin hole and the pin exceeds the process requirement upper limit. If the pressure is less than a certain threshold when the press pin process is completed and the press riveting process has not started, the device will alarm and stop the riveting operation of the workpiece, indicating that the interference amount of the pin and the pin hole is too small to meet the process requirement. If the device monitors that the pressure value is greater than 12KN during the press riveting process, the device will alarm and stop, indicating that the riveting stroke has exceeded the process requirement at this time, so as to protect the device from overloading.

[0047] In some embodiments, the pointer frame pin has a diameter of only 1.6 mm, and the yield strength of the material itself is about 200-240 MPa.
