Description

Technical Field

[0001] This invention relates to the field of dispensing manufacturing technology, and in particular to an integrated machine for assembling steel ball pressing pins. Background Technology

[0002] Intelligent press-fitting of pins and steel balls is a crucial application in the manufacturing of automotive parts. Typically, press-fitting equipment can only guarantee insertion, not accuracy. High-efficiency production is what every automotive parts manufacturer strives for, saving on space requirements and increasing profits. Currently, standard press-fitting equipment is still used in China, which cannot guarantee accuracy. The press-fitting process for camshaft covers mainly includes: 1) pressing pins; 2) pressing steel balls.

[0003] Typically, pressing equipment can only guarantee insertion, not accuracy. Furthermore, it requires personnel in an inspection area to check the correctness and tightness of each part's insertion, increasing the operator's workload, occupying equipment space, and increasing the overall cycle time per unit. This leads to excessively high investment costs and low profits for the company. Moreover, an extra loading and inspection step increases the chance of product damage, potentially causing customer complaints. Therefore, improving pressing accuracy is a crucial task for companies. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a steel ball pressing pin assembly integrated machine to solve the problem that existing equipment can only press the pin in, but cannot guarantee the position, depth and tightness after pressing, which can easily lead to inaccurate pressing and increase the product defect rate.

[0005] To achieve the above objectives, the present invention provides a steel ball pressing pin assembly integrated machine, comprising a frame, a display, operation buttons and an alarm, a pin pressing mechanism and a steel ball pressing mechanism, and a vibrating feeder feeding mechanism for feeding the pin pressing mechanism and the steel ball pressing mechanism. Both the pin pressing mechanism and the steel ball pressing mechanism include a base plate fixedly connected to the frame, a positioning fixture for clamping parts fixedly connected to the base plate, a guide rod fixedly connected to the base plate, a top plate fixedly connected to the top end of the guide rod, a cylinder fixedly connected to the top plate, and a pin pressing plate or a steel ball pressing plate fixedly connected to the output end of the cylinder.

[0006] The lower surface of the pin-pressing plate is equipped with a pin-pressing head and a sensor 1 for detecting whether there is a pin inside the part. The upper surface of the ball-pressing plate is equipped with a ball-pressing head and a sensor 2 for detecting whether there is a ball inside the part.

[0007] Preferably, the positioning fixture includes four positioning blocks, and the four positioning blocks can move closer to each other or further away from each other under the drive of an external power source.

[0008] Preferably, the pressing head includes a pressure sensor, which is mounted on the pressing plate. A pressing head is mounted on the pressure sensor, and a detection part for detecting whether the pin is pressed into place is fixedly connected to the bottom of the pressing head.

[0009] Preferably, the detection unit includes a sleeve fixedly connected to the pressure head, a sleeve rod slidably connected inside the sleeve, a spring for pushing the sleeve rod downward inside the sleeve, and a sensor three installed on the side of the sleeve rod near the bottom end. When the pressure plate drives the pressure head downward to press the pin into the part, the sleeve drives the sleeve rod to extend into the pin, so that the sensor three can detect whether the bottom of the pin is in contact with the bottom of the pin mounting hole on the part.

[0010] Preferably, the bottom of the pressure head is provided with an annular groove, and an annular electromagnet is installed in the annular groove.

[0011] Preferably, the pressure ball head includes a second pressure sensor mounted on the pressure ball plate, a contact post mounted on the second pressure sensor, and a second pressure head fixedly connected to the bottom of the contact post.

[0012] Preferably, sensor one, sensor two, and sensor three are all laser infrared sensors.

[0013] Preferably, a laser marking device for marking parts after pin installation is provided below the pin plate, and a laser scanner for scanning parts after steel balls are installed is provided below the steel ball pressing plate, with the laser marking device and laser scanner respectively installed on the adjacent base plate.

[0014] The beneficial effects of this invention are as follows: This invention provides a steel ball pressing pin assembly integrated machine. Through the setting of sensor one and sensor two, it can detect whether the part has been pressed into the pin before pressing, and similarly, it can detect whether the steel ball has been pressed into the part before pressing. Furthermore, through the setting of the pressing pin head, it can detect whether the pressing depth of the pin is correct and whether it is tightly pressed after pressing, thus realizing automatic detection of the pressed pin. This saves clamping time, personnel inspection time, and repetitive equipment costs, while also reducing the risk of damage and dimensional defects that may occur from manual pressing back and forth, ensuring production quality. This significantly improves the company's profits.

[0015] In summary, the ball bearing pressing and assembly integrated machine described in this application demonstrates significant efficiency, improves the yield of pressed products, and increases the company's profits. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this invention should have the ordinary meaning understood by those skilled in the art to which this invention pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only 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, a display 2, an operation button 3 and an alarm on the frame 1, a pressing pin mechanism 4 and a steel ball pressing mechanism 5 are provided in the frame 1, and a vibrating plate feeding mechanism for feeding 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 base plate 6 fixedly connected in the frame 1, a positioning fixture for clamping parts is fixedly connected to the base plate 6, a guide rod 7 is fixedly connected to the base 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] The lower surface of the pin-pressing plate 41 is equipped with a pin-pressing head 42 and a sensor 43 for detecting whether there is a pin inside the part. The upper surface of the ball-pressing plate 51 is equipped with a ball-pressing head 52 and a sensor 53 for detecting whether there is a ball inside the part.

[0028] Sensor 43 detects whether the part has been pressed into the pin before pressing it in. Similarly, sensor 53 detects whether the steel ball has been pressed into the part before pressing it in. The pin-pressing head 42 allows for automatic detection of the pin's insertion depth and tightness after pressing, saving clamping time, personnel inspection time, and repetitive equipment costs. It also eliminates the risk of damage and dimensional defects that may occur with manual pressing, ensuring production quality and significantly improving company 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 each other or further 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 pressing head 42 includes a pressure sensor 421, which is mounted on the pressing plate 41. A pressing head 422 is mounted on the pressure sensor 421, and a detection part for detecting whether the pin is pressed into place is fixedly connected to the bottom of the pressing head 422.

[0031] The detection unit 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. A sensor 426 is installed on the side of the sleeve rod 424 near the bottom end. When the pressure plate 41 drives the pressure head 422 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 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 part is loaded into the positioning fixture, the equipment is started, and the four positioning blocks 9 clamp the part. Sensor 43 is a laser infrared sensor that can detect whether a pin has been installed in the mounting hole of the part at a set distance. If the part has already been assembled, the equipment will automatically alarm and there will be no further action. For parts that are not yet assembled, the vibrating feeding mechanism of the vibrating plate will send the pin to the pin pressing position. The cylinder 8 will start and drive the pin pressing plate 41 and the pin pressing head 42 to move down. The downward movement of the pin pressing head 42 will drive the first pressing head 422 to move down, so that the first pressing head 422 can press the pin into the mounting hole of the part. The first pressing head 422 then presses the pin into the mounting hole of the part. During the process of inserting the pin into the mounting hole, the sleeve 423 will drive the sleeve rod 424 to extend into the pin. Under the action of the spring 425, the bottom end of the sleeve rod 424 will contact the bottom of the mounting hole. Because the sensor 3 426 is an infrared laser sensor, the distance measured when the pin is fully installed in the mounting hole is different from the distance when it is not fully installed in the bottom of the mounting hole. This allows the sensor 3 426 to measure whether the pin is fully installed in the bottom of the mounting hole, thereby determining whether the pin is pressed into the correct depth. If the set requirements are not met, the device 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] Then, the annular electromagnet 427 is energized. After being energized, the annular electromagnet 427 generates magnetism. When the cylinder 8 drives the pressure head 422 to move slightly upward, the annular electromagnet 427 will generate a certain attraction force on the pin. Due to the push 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 426 detects a change in 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. Conversely, if the pin is pressed tightly, the cylinder will drive the pressure head 422 to return. After the pin is pressed, the laser marking device 10 will mark the surface of the part.

[0035] It should be noted that the steel ball pressing head 52 includes a pressure sensor 521 mounted on the steel ball pressing plate 51. A contact post 522 is mounted on the pressure sensor 521. A pressing head 523 is fixedly connected to the bottom of the contact post 522. A pressure sensor is provided on the contact post 522. When the contact post 522 moves down, so that the pressure sensor on it contacts the pin in the part mounting hole, the pressing head 523 can press the steel ball into place completely.

[0036] It should be noted that sensor 1 (43), sensor 2 (53), and sensor 3 (426) are all laser infrared sensors.

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

[0038] After the pins are pressed, the parts are loaded into the positioning fixture. The equipment is started, and the four positioning blocks 9 press the parts firmly. Sensor 2 53 detects whether there are pins. If no pins are installed, the equipment automatically alarms to ensure no process is missed. Sensor 2 53 confirms whether the parts have been pressed with steel balls. If so, the equipment alarms to prevent repeated pressing. The feeding mechanism for parts to be assembled normally sends the steel balls to the pressing position. Cylinder 8 starts, driving the pressing plate to move down, which in turn moves the pressing head 2 down. When the contact post 522 moves down, the pressure sensor on it contacts the pin in the part's mounting hole, and the pressing head 2 523 can fully press the steel ball into place. Then, the laser scanner 11 scans the part to ensure traceability and QR code level requirements. Finally, cylinder 8 returns to the loading position. This reduces the quality risk of products during production and increases the company's profit margin.
