[0002] The intelligent pressing pin and pressing steel ball manufacturing field is a very important application. Usually, the pressing pin and pressing steel ball equipment can only guarantee the pressing, but cannot guarantee the accuracy of the pressing. However, this equipment can produce efficiently, which is the pursuit of every automotive parts company. It not only saves the planning of the company's site, but also increases the company's profits. At present, the country is still using standard ordinary pressing equipment, which cannot guarantee the accuracy of pressing. The pressing contents of the camshaft cover mainly include: 1) pressing pin; 2) pressing steel ball;

[0003] Usually, the pressing equipment can only guarantee the pressing, but not the accuracy of the pressing.

In addition, one more loading and inspection will increase the probability of crushing and bruising the product, and will also make the product quality at risk of customer complaints. Therefore, it is an important task for the enterprise to improve the accuracy of pressing. Summary of the invention

[0004] In view of this, the purpose of the present invention is to propose an integrated steel ball press pin assembly machine to solve the problem that the existing equipment can only realize the pressing of the pin, but cannot guarantee the position, depth and tightness after pressing, which easily causes the pressing to be inaccurate and increases the defective rate of the product.

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connecting" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a steel ball pressing pin assembly integrated machine includes a frame 1, on which a display 2, an operation button 3 and an alarm are arranged, a pressing pin mechanism 4 and a steel ball pressing mechanism 5 are arranged in the frame 1, and a vibration plate feeding mechanism for feeding materials to the pressing pin mechanism 4 and the steel ball pressing mechanism 5, the pressing pin mechanism 4 and the steel ball pressing mechanism 5 both include a bottom plate 6 fixedly connected to the frame 1, a positioning fixture for clamping parts is fixedly connected to the bottom plate 6, a guide rod 7 is fixedly connected to the bottom plate 6, a top plate is fixedly connected to the top of the guide rod 7, a cylinder 8 is fixedly connected to the top plate, and a pressing pin plate 41 or a steel ball pressing plate 51 is fixedly connected to the output end of the cylinder 8;

[0027] A pin pressing head 42 and a sensor 43 for detecting whether there is a pin in the part are installed on the lower surface of the pin pressing plate 41, and a steel ball pressing head 52 and a sensor 53 for detecting whether there is a steel ball in the part are installed on the upper surface of the steel ball pressing plate 51.

[0028] Sensor 1 43 can detect whether the part has been pressed into the pin before pressing the pin. Similarly, sensor 2 53 can also detect whether the part has been pressed into the steel ball before pressing the steel ball. Through the setting of the pin head 42, after the pin is pressed, it can detect whether the pressing depth of the pin is correct and whether it is pressed tightly, realizing automatic detection of the pressed pin, thereby saving the clamping time, personnel inspection time, repeated equipment costs, and reducing the risk of bruises and poor quality caused by manual pressing back and forth, ensuring production quality. It brings significant improvement to the company's profits.

[0029] In a preferred embodiment of the present invention, the positioning fixture includes four positioning blocks 9, and the four positioning blocks 9 can move closer to or away from each other under the drive of an external power source. The external power source can be a hydraulic cylinder or an electric push rod. By pushing the four positioning blocks 9 closer to each other through the electric push rod, the parts can be clamped and positioned, making it easier to fix the parts on the placement table.

[0030] In another preferred embodiment of the present invention, the pin pressing head 42 includes a pressure sensor 421, which is mounted on the pin pressing plate 41, and a pressure head 422 is mounted on the pressure sensor 421, and a detection unit for detecting whether the pin is pressed into place is fixedly connected to the bottom of the pressure head 422.

[0031] The detection part includes a sleeve 423 fixedly connected to the pressure head 422, a sleeve rod 424 is slidably connected inside the sleeve 423, a spring 425 for pushing the sleeve rod 424 downward is installed inside the sleeve 423, and a sensor three 426 is installed on the side of the sleeve rod 424 near the bottom end. When the pin pressing plate 41 drives the pressure head 422 to move downward to press the pin into the part, the sleeve 423 drives the sleeve rod 424 to extend into the pin, so that the sensor three 426 can detect whether the bottom of the pin is in contact with the bottom of the pin mounting hole on the part.

[0032] The parts are loaded into the positioning fixture, and the equipment is started. The four positioning blocks 9 press the parts tightly. The sensor 1 43 is a laser infrared sensor, which can detect whether the pins have been installed in the mounting holes of the parts through the set distance. If it is an assembled part, the equipment automatically alarms and no subsequent action is taken. For the parts to be assembled normally, the vibration plate vibrates the feeding mechanism to send the pins to the pressing position. The cylinder 8 is started to drive the pressing plate 41 and the pressing head 42 to move downward. The downward movement of the pressing head 42 will drive the pressing head 422 to move downward, so that the pressing head 422 can press the pin into the mounting hole of the part. The pressing head 422 presses the pin During the process of entering the part mounting hole, the sleeve 423 will drive the sleeve rod 424 to extend into the pin, and the bottom end of the sleeve rod 424 will contact the bottom of the part mounting hole under the action of the elastic force of the spring 425. Because the sensor three 426 is an infrared laser sensor, the distance measured when the pin is fully installed in the part mounting hole is different from the distance when it is not fully installed to the bottom of the part mounting hole. Therefore, the sensor three 426 can measure whether the pin is fully installed to the bottom of the part mounting hole, thereby determining whether the pin's pressing depth is correct. As long as the set requirements are not met, the equipment will detect and alarm.

[0033] It should be noted that an annular groove is provided at the bottom of the pressure head 422, and an annular electromagnet 427 is installed in the annular groove.

[0034] Subsequently, the annular electromagnet 427 is energized, and the annular electromagnet 427 generates magnetism after being energized. When the cylinder 8 drives the pressure head 422 to move slightly upward, the annular electromagnet 427 will generate a certain suction force on the pin. Under the push of the elastic force of the spring 425, the bottom end of the sleeve rod 424 will also contact the bottom of the part mounting hole. If the sensor 3 426 detects a change in the distance when the pressure head 422 moves slightly upward, it proves that the annular electromagnet 427 drives the pin to move upward when the pressure head 422 moves slightly upward. In this case, the pin is not pressed tightly enough and the equipment will issue an alarm. Otherwise, the pin is pressed tightly, and the cylinder drives the pressure head to return. After the pin is pressed, the laser coder 10 will code the surface of the part.

[0035] It should be noted that the steel ball pressing head 52 includes a second pressure sensor 521 installed on the steel ball pressing plate 51, a contact column 522 is installed on the pressure sensor 521, a pressure head 523 is fixedly connected to the bottom of the contact column 522, and a pressure sensor is arranged on the contact column 522. When the contact column 522 moves downward so that the pressure sensor thereon contacts the pin in the part mounting hole, the pressure head 523 can press the steel ball completely into place.

[0036] It should be noted that sensor one 43, sensor two 53 and sensor three 426 are all laser infrared sensors.

[0037] It should be noted that a laser coder 10 for coding the parts after the pins are installed is provided below the pin pressing plate 41, and a laser coder 11 for scanning the parts after the steel balls are installed is provided below the steel ball pressing plate 51, and the laser coder 10 and the laser coder 11 are respectively installed on the base plate 6 adjacent thereto.

[0038] After the pins are pressed, the parts are loaded into the positioning fixture, and the equipment is started. The four positioning blocks 9 press the parts tightly, and the sensor 2 53 detects whether there are pins. If the pins are not assembled, the equipment automatically alarms to ensure that no process is missed. Sensor 2 53 confirms whether the part has pressed the steel ball. If it has pressed the steel ball, the equipment alarms to prevent repeated pressing. The feeding mechanism of the parts to be assembled normally sends the steel ball to the steel ball pressing position. The cylinder 8 starts to drive the steel ball pressing plate to move down, thereby driving the pressure head 2 to move down. When the contact column 522 moves down, the pressure sensor on it contacts the pin in the part installation hole, and the pressure head 2 523 can completely press the steel ball into place. Then the laser scanner 11 scans the parts to ensure the traceability of the parts and the QR code level requirements. Finally, the cylinder 8 returns to the position of loading parts. Reduce the quality risk of products during the production process. Increase the profit margin of the enterprise.
