Description

Technical Field

[0001] The utility model relates to the technical field of parts assembly, in particular to a column nail pressing device. Background Art

[0002] During the manufacturing process of plastic products, metal studs are often required to be assembled into plastic components to meet the product's structural design and functional requirements. This assembly method typically relies on an interference fit between the stud and the plastic component. Specifically, the stud's diameter is slightly larger than the diameter of the pre-recorded hole in the plastic component, allowing a tight connection to be achieved through press-fit. This fit provides excellent mechanical strength and stability, ensuring the reliability and durability of the plastic product during use.

[0003] However, in actual production, due to the typically small size and complex shape of plastic workpieces, and the high precision required for the assembly between the studs and the plastic product, this assembly step currently relies heavily on manual operation. While manual assembly offers a degree of flexibility, workers must exert considerable effort to press the studs into the pre-set holes in the plastic components. This not only increases labor intensity and reduces production efficiency, but also easily leads to unstable assembly quality. Furthermore, due to the limitations of manual operation, there is a risk that the studs may not be fully inserted into the pre-set holes, resulting in poor assembly results and affecting the overall quality and performance of the plastic product.

[0027] See also Figure 1 A device for pressing studs into the workpiece includes a press 100, a tooling base 200, and a press mechanism 300. The tooling base 200 is disposed on the workbench 110 of the press 100, and the press 100 is mounted on the tooling base 200. The tooling base has a workpiece position 210 and a press channel 220 that are interconnected. The output end of the press 100 is connected to the input end of the press mechanism 300, and the output end of the press mechanism 300 is movably inserted into the press channel 220. A plastic product is placed on the workpiece position 210, and studs are placed in the press channel 220. The press 100 drives the press mechanism 300 to press the studs in the press channel 220 into the reserved holes of the plastic product on the workpiece position 210.

[0028] In this embodiment, the press 100 is a manual press 100 , wherein the pressing rod 120 is the input end of the press 100 , and the pressing head 130 is the output end of the press 100 . The pressing rod 120 is driven to drive the pressing head 130 to move up and down.

[0029] See also Figure 1 and 2 The workpiece position 210 is arranged on one side of the tooling base 200, and the press-fitting channel 220 is arranged on the tooling base 200 relative to the workpiece position 210. One end of the press-fitting channel 220 is connected to the workpiece position 210. The shape of the workpiece position 210 is adapted to the shape of the plastic product, allowing the plastic product to be placed on the workpiece position 210 in a directional manner. When the plastic product is placed on the workpiece position 210, one end of the press-fitting channel 220 is opposite to the reserved hole of the plastic product. At the same time, the cross-sectional dimensions of the press-fitting channel 220 are adapted to the diameter of the stud, thereby achieving directional pushing of the stud and ensuring that the stud can be pressed smoothly and accurately into the reserved hole of the plastic product.

[0030] Furthermore, the tooling base 200 has a material position 230 and a blanking channel 240. The material position 230 is used to store studs, and the blanking channel 240 is used to transport studs from the material position 230 to the press-fitting channel 220. The material position 230 is located on the upper side of the tooling base 200, and the blanking channel 240 is located on the side of the material position 230 near the workpiece position 210. One end of the blanking channel 240 is connected to the material position 230, and the other end of the blanking channel 240 is connected to the press-fitting channel 220. The material position 230 stores multiple studs, which are then manually pushed into the blanking channel 240. The studs move along the blanking channel 240 and then enter the blanking channel 240.

[0031] In this embodiment, the bottom wall of the material position 230 has a slope 231, located near the bottom of the material position 230. This slope 231 facilitates the operator's alignment of the studs, allowing them to be smoothly and orientably pushed into the material channel 240. Furthermore, the material channel 240 is inclined toward the press-fitting channel 220, allowing the studs to naturally roll along the material channel 240 under the action of gravity and smoothly fall into the press-fitting channel 220. Furthermore, the width of the material channel 240 is adapted to the length of the studs, ensuring that it can accommodate only a single row of studs.

[0032] See also Figure 1 and 5 The press-fitting mechanism 300 includes a reversing pressure block 310 and a press-fitting pin 320. The reversing pressure block 310 is movably disposed in the actuating chamber 250 of the tooling seat 200 along the stroke direction of the ram 130. The press-fitting pin 320 is movably inserted into the guide channel 260 of the tooling seat 200. One end of the guide channel 260 is interconnected with the press-fitting channel 220, and the other end of the guide channel 260 is interconnected with the actuating chamber 250. The reversing pressure block 310 is connected to the ram 130 and is slidably connected to one end of the press-fitting pin 320. The other end of the press-fitting pin 320 is movably inserted into the press-fitting channel 220. The driving rod 120 drives the ram 130 to move up and down, and the reversing pressure block 310 moves with the ram 130. During the movement of the reversing pressure block 310, the press-fitting pin 320 is driven to move along the arrangement direction of the press-fitting channel 220.

[0033] Specifically, a guide post 251 is provided at the bottom of the actuating chamber 250. The reversing pressure block 310 is slidably mounted on the guide post 251. Restricted by the guide post 251, the reversing pressure block 310 moves along the stroke direction of the pressure head 130. Furthermore, a first spring 330 is mounted on the guide post 251 to reset the reversing pressure block 310. One end of the first spring 330 abuts against the reversing pressure block 310, while the other end abuts against the bottom of the actuating chamber 250.

[0034] Furthermore, a first inclined surface 311 is provided on the reversing pressure block 310, and a second inclined surface 321 is provided on the end of the press pin 320 close to the reversing pressure block 310. The first inclined surface 311 and the second inclined surface 321 are slidably connected. Through the cooperation between the first inclined surface 311 and the second inclined surface 321, the driving direction of the press 100 is converted, and under the restriction of the guide channel 260, the press pin 320 is driven to move along the arrangement direction of the press channel 220.

[0035] Furthermore, the press-fit pin 320 is provided with a second spring 340, which is used to retract and reset the press-fit pin 320. One end of the second spring 340 abuts against the end of the press-fit pin 320 near the reversing pressure block 310, while the other end of the second spring 340 abuts against the end of the guide channel 260. In this embodiment, the press-fit pin 320 is also provided with a stopper 322, which prevents it from passing through the press-fit channel 220, thereby limiting the length of the press-fit pin 320 near the press-fit channel 220.

[0036] To sum up, the pressing device consists of a press, a tooling base and a pressing mechanism. The press drives the pressing mechanism to press the column nail in the pressing channel into the reserved hole of the plastic product on the workpiece. The press provides a stable and controllable output force, which is transmitted to the column nail through the pressing mechanism, so that it can be pressed accurately and deeply into the reserved hole of the plastic product, realizing efficient and precise assembly of plastic products and column nails, solving the common problems of column nails not being pressed into place and unstable assembly quality in manual assembly, significantly improving assembly efficiency, and effectively reducing the labor intensity and instability caused by manual assembly, thereby ensuring the stability and consistency of product assembly quality, and providing a strong guarantee for the high-quality assembly of small plastic products and metal parts.
