Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a precision positioning pin presser includes a machine frame 1 and a pressing cylinder 2 fixedly installed on the machine frame 1. The output end of the pressing cylinder 2 is fixedly connected to a pressing rod 3. A movable plate 5 is fixedly installed on the outside of the pressing rod 3. The movable plate 5 is slidably installed inside the machine frame 1. A pressing plate 7 is fixedly installed on one side of the movable plate 5. Lever pressing rods 8 are installed around the bottom of the pressing plate 7.

[0025] Multiple sets of sleeve columns 11 are fixedly installed at the bottom of the equipment frame 1. A movable seat 9 is slidably installed on the sleeve column 11. Multiple sets of positioning pin sleeves 4 for connecting product pins are provided inside the movable seat 9. An adjustment component 6 is provided at the bottom of the positioning pin sleeve 4. The adjustment component 6 is used to fine adjust the position between the multiple sets of positioning pin sleeves 4.

[0026] In this embodiment, the product that needs to be pressed is placed on the movable seat 9. After determining the corresponding positioning pin sleeve 4 according to the hole position on the product housing, the position between multiple sets of positioning pin sleeves 4 is finely adjusted by the adjustment component 6 until the positioning pin sleeve 4 corresponds to the hole position on the product housing. The cotter pin is then placed outside the positioning pin sleeve 4.

[0027] The clamping cylinder 2 drives the clamping rod 3 and the clamping plate 7 to move, applying pressure to the product housing. The product housing and the moving seat 9 are pressed downward outside the sleeve 11, so that the hole of the product housing enters the positioning pin sleeve 4 with cotter pin. This ensures that the positioning pin sleeve 4 and the hole of the product housing are accurately aligned, avoiding misalignment that could cause the pin to be pressed crooked, damage the product, or cause installation failure.

[0028] As one implementation method, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjustment assembly 6 includes a screw 13 that passes through one side of the movable seat 9. One end of the screw 13 is fixedly mounted with a throttle 12. The bottom ends of two adjacent sets of positioning pin sleeves 4 are movably mounted with connecting rods 14. There are two sets of connecting rods 14. The other end of the screw 13 is movably connected to one set of connecting rods 14.

[0029] Two sets of swing arms 15 are movably connected between two adjacent sets of connecting rods 14. The two sets of connecting rods 14 and the two sets of swing arms 15 together form a quadrilateral structure. The positioning pin sleeves 4 are located at the ends of the quadrilateral. The insert shaft 16 passes through the center of the swing arm 15. The end of the other set of connecting rods 14 is connected to a spring 17. The other end of the spring 17 is connected to the inner wall of the moving seat 9.

[0030] In this embodiment, after determining the corresponding positioning pin sleeve 4 according to the hole position on the product housing, the screw 13 is rotated by rotating the handle 12. The screw 13 drives one set of connecting rods 14 to move. Since the two sets of connecting rods 14 are hinged to the two sets of swing rods 15, when one set of connecting rods 14 moves, it pulls the other set of connecting rods 14 to move in the opposite direction, adjusting the position of multiple sets of positioning pin sleeves 4. When the pressing cylinder 2 is pressed in, it ensures that the positioning pin sleeve 4 is accurately aligned with the hole position on the product housing, avoiding misalignment that could cause the pin to be pressed crooked, damage the product, or cause installation failure.

[0031] As one implementation method, such as Figure 2 , Figure 3 As shown, the movable seat 9 and the pressing plate 7 are arranged parallel to each other vertically, and the lever pressure rod 8 and the positioning pin sleeve 4 are arranged correspondingly.

[0032] The top of the movable seat 9 is provided with a groove for the movement of the positioning pin sleeve 4, which facilitates the fine adjustment of the positioning pin sleeve 4 inside.

[0033] In this embodiment, the pressing cylinder 2 drives the pressing rod 3 and the movable plate 5 to move downward. When the pressing plate 7 installed on one side of the movable plate 5 moves, it applies pressure to the product shell through the lever 8 at the bottom, and the entire product shell and the movable seat 9 are pressed downward to prevent product deformation or displacement caused by uneven force during the pressing process, and to ensure the stability and repeatability of the pressing process.

[0034] As one implementation method, such as Figure 3 As shown, the movable seat 9 has a limiting platform 18 for positioning the product inside. The limiting platform 18 is located between multiple sets of positioning pin sleeves 4, and the top of the positioning pin sleeve 4 is chamfered.

[0035] In this embodiment, when the product housing has a groove, the groove is aligned with the limiting platform 18. When the product has no groove, the limiting platform 18 is disassembled and placed directly on the movable seat 9, thus achieving rapid adaptation to products with different structures. The top of the positioning pin sleeve 4 is chamfered to facilitate the insertion of a cotter pin.

[0036] As one implementation method, such as Figure 1 and Figure 3 As shown, a travel stop 10 is provided between the movable seat 9 and the equipment platform 1. The movable seat 9 is sleeved on the outside of the travel stop 10, and the travel stop 10 has a stepped structure.

[0037] In this embodiment, the pressing stroke of the product housing is precisely controlled by the cooperation of the sleeve 11 and the stroke stop 10, ensuring that the cotter pin is pressed into the predetermined depth, avoiding pressing too deeply or too insufficiently, and ensuring the consistency of assembly quality.

[0038] Working principle: When in use, the product that needs to be pressed is placed on the moving base 9. When the product shell has a groove, the groove is aligned with the limiting platform 18. When the product does not have a groove, the limiting platform 18 is removed and placed directly on the moving base 9, which realizes the quick adaptation of products with different structures. After determining the corresponding positioning pin sleeve 4 according to the hole position on the product shell, the screw 13 is rotated by turning the handle 12. The screw 13 drives one set of connecting rods 14 to move. Since the two sets of connecting rods 14 are hinged to the two sets of swing rods 15, when one set of connecting rods 14 moves, it pulls the other set of connecting rods 14 to move in the opposite direction, adjusting the position of multiple sets of positioning pin sleeves 4.

[0039] Until the positioning pin sleeve 4 aligns with the hole on the product housing, the cotter pin is placed outside the positioning pin sleeve 4. The clamping cylinder 2 drives the clamping rod 3 and the movable plate 5 to move downwards. When the clamping plate 7 installed on one side of the movable plate 5 moves, it applies pressure to the product housing through the lever 8 at the bottom. The entire product housing and the movable seat 9 are pressed downwards outside the sleeve 11 until they contact the stroke stop 10, so that the hole in the product housing enters the positioning pin sleeve 4 with the cotter pin. The cotter pin is pressed into the product housing, ensuring that the cotter pin is pressed into the predetermined depth, avoiding pressing too deeply or too little. The entire process, from positioning, releasing the pin, clamping to pressing in, reduces manual intervention, improves assembly efficiency, and reduces the difficulty and labor intensity of operation.
