Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to a radiator stud press-fitting device. Background Technology

[0002] like Figure 1 The image shows a heat sink, which includes a horizontally arranged heat sink plate 26 on top and multiple longitudinally distributed heat sink fins 27 integrally formed below the heat sink plate. When it is assembled into a device as a whole, studs need to be press-fitted into the mounting holes 28 on its heat sink plate.

[0003] In existing technologies, the process of pressing studs into mounting holes is mostly done manually. While some use mechanical equipment, existing pressing equipment generally suffers from the following drawbacks: 1. The equipment lacks a pressure testing structure, making it difficult to monitor the force applied by each pressing rod to the stud, potentially leading to defective assembly of individual studs; 2. The pressing rod design is inadequate, with the pressing head directly bearing the load without force buffering and inconvenient adjustment of the buffer distance; 3. The overall structure is complex, and the pressing head is difficult to disassemble.

[0004] Therefore, how to provide a radiator stud press-fitting device with a simpler and more reasonable structural design, which can better detect the press-fitting force to ensure the press-fitting qualification, and can better buffer the press-fitting force and adjust the buffering distance, has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a radiator stud press-fitting device with a simpler and more reasonable structural design, which can better detect the press-fitting force to ensure the press-fitting qualification, and can better buffer the press-fitting force and adjust the buffering distance.

[0006] To achieve the above objectives, this utility model provides a radiator stud pressing device, comprising a horizontally arranged base plate inside a housing, forming a support station on the base plate for placing the radiator; a stud pressing structure is provided above the base plate, the stud pressing structure including a mounting plate at the lower end; characterized in that; mounting cylinders are installed on the mounting plate and corresponding to the mounting holes on the radiator, and a pressure sensor is installed at the upper end of the mounting cylinder; a connecting cylinder is connected to the lower end of the mounting cylinder, and the upper end of the connecting cylinder extends into the mounting cylinder; a push rod is provided inside the mounting cylinder, and the lower end of the push rod extends into the connecting cylinder; a pressure rod is vertically slidable at the lower end of the connecting cylinder, and a pressure rod limiting structure is provided between the pressure rod and the connecting cylinder to prevent the pressure rod from disengaging from the lower end of the connecting cylinder; and after the pressure rod applies pressure to the stud, the pressure rod can slide upward in the connecting cylinder and push the push rod upward, so that the upper end of the push rod abuts against the pressure sensor.

[0007] In this way, when the aforementioned radiator stud press-fitting equipment presses the studs into the mounting holes on the radiator, the press rod applies pressure to the studs. After the press rod is subjected to pressure, it slides upward in the connecting cylinder and pushes the push rod upward, so that the upper end of the push rod abuts against the pressure sensor. The pressure sensor detects the pressing force corresponding to the press-fitting stud, and can detect the force on each stud during press-fitting, thereby better ensuring the studs are press-fitted and improving the reliability and pass rate of stud press-fitting.

[0008] As an optimization, the pressure rod limiting structure includes a limiting protrusion at the lower end of the inner circumference of the connecting cylinder; the pressure rod includes an upper section and a lower section, and the diameter of the upper section is set to be larger than the diameter of the lower section; and the upper side of the limiting protrusion can be supported against the stepped surface formed by the upper and lower sections of the pressure rod to restrict the pressure rod from coming off the lower end of the connecting cylinder.

[0009] In this way, the design of the pressure bar limiting structure is simpler and the limiting is more reliable.

[0010] As an optimization, the diameter of the upper section of the pressure rod is matched with the diameter of the inner hole of the connecting cylinder.

[0011] This ensures that the upper section of the pressure rod matches the inner hole of the connecting cylinder, better reducing pressure rod offset and improving press-fit reliability.

[0012] As an optimization, the push rod includes an upper push rod section and a lower push rod section, and the diameter of the upper push rod section is set to be larger than the diameter of the lower push rod section. The upper push rod section and the lower push rod section are respectively located inside the mounting cylinder and the connecting cylinder, and the stepped surface formed between the upper push rod section and the lower push rod section can be abutted and supported on the upper end surface of the connecting cylinder to limit the vertical position of the push rod inside the mounting cylinder.

[0013] This makes the push rod's structural design simpler and more reasonable, allowing it to maintain vertical sliding better.

[0014] As an optimization, a lower receiving hole and an upper receiving hole are respectively provided on the upper end face of the pressure rod and the lower end face of the push rod. A helical spring is provided between the upper end of the pressure rod and the lower end of the push rod, and the two ends of the helical spring extend into the lower receiving hole and the upper receiving hole respectively, so that the push rod and the pressure rod have a tendency to move away from each other.

[0015] In this way, by setting a helical spring, the upper end face of the pressure rod and the lower end face of the push rod are spaced apart under the action of the helical spring. When pressing the stud, the helical spring is first compressed and then plays a buffering role. Finally, the pressing force increases and the upper end face of the pressure rod and the lower end face of the push rod come into contact.

[0016] As an optimization, the diameter of the upper section of the push rod is matched with the diameter of the inner hole of the mounting cylinder; the diameter of the lower section of the push rod is matched with the diameter of the inner hole of the connecting cylinder.

[0017] This allows the push rod to maintain vertical movement more effectively.

[0018] As an optimization, the upper end of the mounting cylinder is provided with an external thread, and the upper end of the mounting cylinder is threadedly connected to a threaded hole on the mounting plate; a mounting block is provided at the upper end of the mounting cylinder, and a threaded connection hole is provided on the lower surface of the mounting block, so that the upper end of the mounting cylinder is threadedly connected to the threaded connection hole of the mounting block, and the lower end of the mounting block can be supported against the surface of the mounting plate; and the pressure sensor is provided inside the threaded connection hole, and a through hole is also provided on the mounting block for the connection wire of the pressure sensor to pass through to the outside.

[0019] This makes the connection between the mounting cylinder and the mounting plate simpler, more reliable, and easier to assemble and disassemble. It also makes it easier to install and arrange the pressure sensor.

[0020] Furthermore, a locking nut is provided on the mounting cylinder, and the locking nut can abut against and support the lower surface of the mounting plate.

[0021] As an optimization, at least a portion of the lower end of the inner hole of the mounting cylinder is an internal thread section, and at least a portion of the upper end of the outer circumferential surface of the connecting cylinder is an external thread section, so that the upper section of the connecting cylinder is threadedly connected to the lower end of the mounting cylinder.

[0022] This makes the connection between the mounting cylinder and the connecting cylinder simpler and easier to assemble and disassemble; it also allows for adjustment of the length of the connecting cylinder extending into the mounting cylinder, thereby adjusting the buffer distance.

[0023] As an optimization, a mating opening is provided on the lower end face of the pressure rod, and the diameter of the mating opening matches the diameter of the stud to be press-fitted.

[0024] This helps to better prevent the studs from becoming misaligned during press-fitting.

[0025] As an optimization, the overall housing is designed as a rectangular box structure, with operating openings on both the front and rear sides of the housing.

[0026] This makes the shell structure simpler and easier to operate.

[0027] As an optimization, the stud press-fitting structure also includes a support plate set above the mounting plate, with multiple vertically arranged connecting rods between the mounting plate and the support plate; a vertically arranged cylinder is also set above the outer shell; the piston rod ends of the cylinders are respectively connected to the fixing holes provided on the support plate and the mounting plate; guide sleeves are provided at both ends of the support plate and both ends of the mounting plate, and vertically arranged guide posts are arranged in the vertically paired guide sleeves, such that the upper and lower ends of the guide posts are respectively installed and fixed on the fixing blocks at the upper and lower ends inside the outer shell.

[0028] In this way, the design of the stud pressing section is simpler and more reasonable, which can better drive the vertical movement of the mounting plate and make the pressing rod complete the pressing of the stud.

[0029] In summary, the above-mentioned structure has the advantages of simpler and more reasonable structural design, better detection of pressing force to ensure pressing qualification, better buffering of pressing force and adjustment of buffer distance. Attached Figure Description
