Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1As shown, an embodiment of this application provides a traction pin pressing mechanism, including a carrier mechanism 1 for fixing a product, a pressing mechanism 2 for assembling a traction pin on the product, and a positioning mechanism 3 for positioning the product. The pressing mechanism 2 includes a support frame 21, a fixing component 22 for placing the traction pin, and a pressing component 23 for pressing down the traction pin in the fixing component 22. The pressing component 23 and the fixing component 22 are respectively mounted on the support frame 21.

[0026] like Figure 2 As shown, the pressing assembly 23 includes a connecting frame 231, a pressing drive mechanism 232, a pressing rod 233, and a guide assembly 234. The connecting frame 231 is installed on the top of the support frame 21, and the pressing drive mechanism 232 is installed on the top of the connecting frame 231. The driving end of the pressing drive mechanism 232 is connected to the pressing rod 233 through a fixed plate 235. The pressing rod 233 passes through the guide assembly 234 and the support frame 21 and extends into the fixed assembly 22 opposite to the traction pin. The guide assembly 234 is sleeved on the connecting frame 231 and slides with the connecting frame 231.

[0027] like Figure 2 As shown, the fixing component 22 includes a fixing plate 221, a cover plate 222, a first driving component 223 for driving the cover plate 222 to close onto the fixing plate 221, and a limiting component 224 for limiting the closed cover plate 222. One end of the cover plate 222 is hinged to the fixing plate 221, and a receiving groove 225 is provided between the fixing plate 221 and the cover plate 222 to accommodate the traction pin and the pressure rod 233.

[0028] Specifically, the product to be assembled is manually fixed onto the carrier mechanism 1, and the positioning mechanism 3 positions the product to prevent it from shaking or shifting during assembly. Then, the feeding mechanism moves the vertically positioned traction pin onto the fixing plate 221, positioning it in the receiving groove 225 with the large end facing up and the small end facing down. The first driving component 223 drives the cover plate 222 to close onto the fixing plate 221, and the limiting component 224 limits the closed cover plate 222 to prevent it from loosening from the fixing plate 221 during the pressing process of the traction pin. Next, the downward drive mechanism 232 drives the fixed plate 235 to move the pressure rod 233 downward. The pressure rod 233 extends into the receiving groove 225 of the fixed plate 221 and the cover plate 222. When the fixed plate 235 moves downward and abuts against the guide assembly 234, the downward drive mechanism 232 drives the fixed plate 235 to move the pressure rod 233 and the guide assembly 234 further downward. The guide assembly 234 stabilizes and protects the pressure rod 233. The downward movement of the pressure rod 233 pushes the traction pin in the receiving groove 225 out of the fixed plate 221 and the cover plate 222. Then, the traction pin extends into the product below and is assembled around the installation part of the product. After the traction pin is assembled, the downward drive mechanism 232 drives the pressure rod 233 to move upward back to the initial position. The first cylinder 101 of the guide assembly 234 drives the guide plate 100 to move the two guide posts 102 upward back to the initial position.

[0029] In the above structure, the press-fitting operation of the traction pin is achieved by the cooperation of the carrier mechanism 1, the pressing mechanism 2, and the positioning mechanism 3. Furthermore, by providing a guide component 234 on the pressure rod 233, the stability of the pressure rod 233 during pressing is ensured, preventing bending, breakage, or other issues. This traction pin press-fitting mechanism not only improves pressing efficiency and saves time and labor costs, but also enhances the stability of the pressure rod 233 during pressing.

[0030] like Figure 2As shown, in one embodiment, the guide assembly 234 of the traction pin pressing mechanism includes a guide plate 100, a first cylinder 101, and two guide posts 102. The four corners of the guide plate 100 are connected to the connecting frame 231 through guide sleeves 103. The first cylinder 101 is mounted on the connecting frame 231, and the driving end of the first cylinder 101 passes through the connecting frame 231 and is connected to the guide plate 100. The two guide posts 102 are symmetrically mounted at the bottom of the guide plate 100. The two guide posts 102 are slidably engaged with the support frame 21. Two sliding grooves 226 for the guide posts 102 to extend into are provided between the fixing plate 221 and the cover plate 222. When the pressing drive mechanism 232 drives the fixed plate 235 and the pressure rod 233 to move downwards, and the fixed plate 235 abuts against the guide plate 100, the fixed plate 235 drives the guide plate 100 to move downwards together. The guide plate 100 drives the two guide pillars 102 and the pressure rod 233 to move downwards simultaneously. The pressure rod 233 extends into the receiving groove 225, and the two guide pillars 102 extend into the sliding groove 226 between the fixed plate 221 and the cover plate 222. When the pressing drive mechanism 232 drives the fixed plate 235 and the pressure rod 233 to move upwards back to the initial position, the first cylinder 101 drives the guide plate 100 to drive the two guide pillars 102 upwards back to the initial position. The arrangement of the guide plate 100 and the guide pillars 102 improves the stability of the pressure rod 233 during downward pressing, preventing bending or breakage of the pressure rod 233 and extending its service life. The arrangement of the first cylinder 101 facilitates driving the guide plate 100 and the guide pillars 102 back to the initial position.

[0031] like Figure 3 and Figure 4As shown, in one embodiment, the first drive assembly 223 of the traction pin pressing mechanism includes a mounting plate 104, a second cylinder 105, a first connecting plate 106, and a second connecting plate 107. The mounting plate 104 is mounted on one end of the fixed plate 221. The second cylinder 105 is hinged to the mounting plate 104, and the drive end of the second cylinder 105 is connected to the first connecting plate 106. The first connecting plate 106 is hinged to the second connecting plate 107, and the second connecting plate 107 is fixedly connected to the cover plate 222. The second cylinder 105 drives the first connecting plate 106 to rotate the second connecting plate 107 and the cover plate 222 around the fixed plate 221. When a traction pin is placed inside the fixed plate 221, the second cylinder 105 drives the first connecting plate 106 to move forward, and the first connecting plate 106 drives the second connecting plate 107 and the cover plate 222 to rotate around the fixed plate 221, so that the cover plate 222 closes onto the fixed plate 221. After the traction pin is assembled onto the product, the second cylinder 105 drives the first connecting plate 106 to move backward. The first connecting plate 106 then drives the second connecting plate 107 and the cover plate 222 to rotate outward around the fixed plate 221, causing the cover plate 222 to open from the fixed plate 221. This arrangement improves the efficiency of closing and opening the cover plate 222, facilitating the feeding mechanism's material unloading operation.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, the limiting component 224 of the traction pin pressing mechanism includes a third cylinder 108 and a limiting post 109. The third cylinder 108 is mounted on the support frame 21, and its driving end is connected to the limiting post 109. The cover plate 222 is provided with a limiting hole 110 for positioning and engaging with the limiting post 109. The third cylinder 108 drives the limiting post 109 to extend into the limiting hole 110 of the cover plate 222 to limit the cover plate 222. When the cover plate 222 is closed on the fixed plate 221, the third cylinder 108 drives the limiting post 109 to move downward and extend into the limiting hole 110 of the cover plate 222, thus limiting the cover plate 222. After the traction pin pressing is completed, the third cylinder 108 drives the limiting post 109 to move upward and disengage from the cover plate 222, allowing the cover plate 222 to be opened from the fixed plate 221. This setting serves to limit the cover plate 222, preventing the cover plate 222 from loosening from the fixing plate 221 during the pressing process.

[0033] like Figure 5 and Figure 6 As shown, in one embodiment, the carrier mechanism 1 of the traction pin pressing mechanism includes a base 11 and a carrier platform 12. The carrier platform 12 is mounted on the base 11 and is used to position the product. This arrangement facilitates the fixing of the product.

[0034] like Figure 5 and Figure 6As shown, in one embodiment, the positioning mechanism 3 of the traction pin pressing mechanism includes a fixed frame 31, a horizontal drive mechanism 32, and a positioning plate 33. The horizontal drive mechanism 32 is mounted on the fixed frame 31, and its drive end is connected to the positioning plate 33. The positioning plate 33 is slidably engaged with the fixed frame 31. A positioning head 34 is provided on the positioning plate 33. The horizontal drive mechanism 32 drives the positioning plate 33 to move the positioning head 34 into the product positioning hole to position the product. When the product is fixed on the carrier platform 12, the horizontal drive mechanism 32 drives the positioning plate 33 to move the positioning head 34 toward the product, and the positioning head 34 extends into the product's positioning hole to position the product. The horizontal drive mechanism is a motor. This arrangement ensures the stability of the product fixation, prevents the product from shaking during assembly, and improves the product assembly yield.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the support frame 21 of the traction pin pressing mechanism has a support component 4 at the end away from the positioning mechanism 3 for supporting the product on the carrier mechanism 1. The support component 4 includes a third connecting plate 41 and a support plate 42. The two ends of the third connecting plate 41 are connected to the support frame 21, and the support plate 42 is horizontally mounted on the third connecting plate 41, supporting one end of the product. When the positioning mechanism 3 positions one end of the product on the carrier mechanism 1, the product moves backward under force, and the support plate 42 of the support component 4 abuts against the other end of the product, providing support. This arrangement facilitates cooperation with the positioning mechanism 3 to support and fix the product.

[0036] like Figure 3 As shown, in one embodiment, the fixing plate 221 of the traction pin pressing mechanism is provided with a groove 227 for the clamps of the feeding assembly to pass through, which is used to place the traction pin. This arrangement facilitates the feeding mechanism to place the traction pin onto the fixing plate 221.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
