Abstract
Description
Technical Field
[0001] The utility model relates to the field of automatic nailing, in particular to a multi-station automatic nailing device with a pre-pressing function. Background Art
[0002] Some machined parts require nailing during processing. After the pins are nailed in, they can be used as positioning and connection structures in the subsequent processing of the machined parts. Therefore, the position of the pins must be accurate, that is, the nailing accuracy must be ensured.
[0003] Traditional nailing operations are often completed manually or with nailing devices. Manual nailing is inefficient, and for products with multiple nails, the force applied each time cannot be completely consistent, resulting in poor product quality. Furthermore, manual nailing requires a significant amount of manpower, resulting in high labor costs. Consequently, automated nailing devices have emerged on the market. Current nailing devices primarily use a pneumatic cylinder or other motion mechanism to drive a pressing head downward, securing the pin to the machined part. However, for multi-nail structures, multiple independent pneumatic cylinders or other motion mechanisms are required, which can easily lead to asynchronous operation and nailing deviation, resulting in poor product quality.
[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content
[0005] The utility model aims to provide a multi-station automatic nail shooting device with a pre-pressing function.

[0008] The crimping mechanism is arranged above the product placement table, and the crimping mechanism includes a first driving member and a crimping member. When driven by the first driving member, the crimping member moves perpendicular to the product placement table; wherein,
[0009] The crimping part includes a crimping head and a pre-compression elastic structure. The pre-compression elastic structure extends to the bottom of the crimping head in a natural state, and under the driving, presses the surface of the product on the product placement table before the crimping head.
[0010] Preferably, the crimping head includes an upper crimping head and a lower crimping head, the upper crimping head is detachably mounted on the lower end of the driving member, and the lower crimping head is detachably connected to a countersunk hole at the lower end of the upper crimping head.

[0014] Preferably, a first positioning structure is provided on the product placement table, and the first positioning structure includes a guide block, and the guide block is arranged to fit the contour of the product to be processed.
[0015] Preferably, a second positioning structure is provided on the product placement table, and the second positioning structure includes a positioning bushing corresponding to the pin.

[0036] See attached Figure 1-4 As shown, a multi-station automatic nailing device with a pre-pressing function includes a product placement table 1 and a crimping mechanism 2.
[0037] Among them, the crimping mechanism 2 is arranged above the product placement table 1, a working box 3 is fixed on the product placement table 1, the crimping mechanism 2 is fixed on the working box 3, and an operation entrance 31 is provided on the front side of the working box 3, and the operation entrance 31 can be used to insert the machined parts 12 products and pins 11.
[0038] The crimping mechanism 2 includes a first driving member 21 and a crimping member 22 . Driven by the first driving member 21 , the crimping member 22 moves perpendicularly to the product placement table 1 .
[0039] The first driving member 21 and the crimping member 22 can be provided in different numbers according to the number and position of the pins on the machined part 12. One crimping member 22 is installed at the lower end of one first driving member 21. In this embodiment, two pins 11 need to be placed on the machined part 12, so two first driving members 21 and two crimping members 22 are used to operate them respectively. Figure 1 .
[0040] The first driving member 21 can be a crimping cylinder, and the two crimping cylinders can be controlled by two start buttons 4 respectively, and the start buttons 4 are respectively set on the front side of the product placement table 1. In order to flexibly control and ensure safety, an emergency stop button 10 is also set on the front side of the product placement table 1, which can shut down the two crimping cylinders at any time. Figure 2 In other embodiments, the first driving member 21 may also be a linear driving mechanism such as a lead screw.
[0041] For safe operation, safety gratings 5 are installed on both sides of the operation entrance 31. The safety gratings 5 and the crimping cylinders are electrically connected to a PLC controller 6. If a hand is detected to have accidentally entered the working box 3 during nailing, a signal is sent to the PLC controller 6, which shuts down the two crimping cylinders.
[0042] The control principle, control method and communication of the PLC controller 6 are existing technologies and are mature technologies that can be mastered by those skilled in the art. The control and communication between the PLC controller 6 and the cylinder, safety light grid, etc. are also widely used in the existing technology. Since they are not the invention points of this case, they will not be described in detail in this case.
[0043] See attached Figure 3-4 As shown, the crimping part 22 includes a crimping head and a pre-stressing elastic structure. The pre-stressing elastic structure extends to the bottom of the crimping head in a natural state, and under the drive, presses the surface of the product on the product placement table 1 before the crimping head, so as to give the machined part 12 a pre-pressure, thereby solving the problem of the machined part 12 tilting due to the asynchronous operation of the two independent crimping cylinders, and then the nailing deviation. For some situations where the pin 11 is needed to position the machined part 12 in subsequent processing steps, the problem of inaccurate position of the pin 11 is also solved, thereby avoiding affecting the quality of the machined part 12.
[0044] Among them, the crimping head includes an upper pressure head 221 and a lower pressure head 222. The upper pressure head 221 is made of stainless steel and can be detachably installed at the lower end of the driving part. The lower pressure head 222 is made of SKD11 heat-treated mold steel with good strength and wear resistance. The lower pressure head 222 can be detachably connected to the countersunk hole at the lower end of the upper pressure head 221. Generally, the two pressure heads can be connected by screws, and the upper pressure head 221 can be connected to the lower end of the crimping cylinder by thread or screw.
[0045] The pre-compression elastic structure includes an elastic pressure plate 223, which slidably engages with a lug 225 on the crimping head via at least two guide posts 224. Each guide post 224 is sheathed with a spring 227. The lug 225 is integrally formed with the upper pressing head 221. The guide posts 224 have a T-shaped cross-section, with the T-shaped head located at the top of the lug 225, preventing the elastic pressure plate 223 from disengaging from the lug 225.
[0046] In this embodiment, since there are only two pins 11, the two elastic pressure plates 223 are both configured to be annular and surround the outside of the crimping head. In other embodiments, the shape of the elastic pressure plates 223 can also be adjusted according to the number and distribution of the pins 11.
[0047] In order to avoid wearing the surface of the machined part 12 and improve the stability of the pressed part, an elastic gasket 226 is bonded to the bottom of the elastic pressing plate 223. The elastic gasket 226 can be made of rubber, silicone or soft plastic.
[0048] See attached Figure 1-2 As shown, in the existing product production, the lack of positioning pins 11 often causes deformation after hitting the machined parts 12, affecting the production quality. Therefore, the product placement table 1 is provided with a first positioning structure and a second positioning structure.
[0049] The first positioning structure includes a guide block 7, which is arranged to fit the contour of the product to be processed. Since the machined part 12 is a hollow interface, it has internal and external contours. Therefore, in order to accurately position the machined part 12 and prevent it from being misplaced, the guide blocks 7 can be respectively arranged at the internal and external contours of the machined part 12, and their number and distribution are based on the ability to accurately position the machined part 12.
[0050] The second positioning structure includes a positioning bushing 8 , which corresponds to the pin 11 and can locate the position of the pin 11 .
[0051] See attached Figure 1 As shown, the multi-station automatic nail shooting device also includes a plate taking mechanism 9 arranged below the product placement table 1, and the plate taking mechanism 9 includes a second driving member 91, a material taking plate 92 and a plurality of plate taking support pins 93.
[0052] In this embodiment, four plate-taking support pins 93 are evenly spaced. Each plate-taking support pin 93 is fixed to the pick-up plate 92 and extends through the product placement table 1. The pick-up plate 92 is driven by the second drive member 91, which drives each plate-taking support pin 93 to extend through the product placement table 1. The second drive member 91 is a plate-taking cylinder, which is signal-connected to the PLC controller 6. In other embodiments, the second drive member 91 may also be a linear drive mechanism such as a lead screw.
[0053] In order to automatically remove the parts, a cylinder position sensor is also provided in the crimping cylinder. When the crimping cylinder finishes nailing and returns, the cylinder position sensor transmits a signal to the PLC controller 6, which controls the plate-removing cylinder to work and push the machined part 12 upward.
[0054] The nailing process: first place the machined part 12 on the product placement table 1, position it with the guide block 7, place the two pins 11 in the holes of the positioning bushing 8, and press the two start buttons 4 at the same time. The crimping cylinder moves and the two crimping parts 22 are pressed down. At this time, the spring pressure plate will first press the two ends of the machined part 12 to pre-press and stabilize the machined part 12. The crimping cylinder drives the crimping parts 22 to continue pressing down until the two crimping heads press down the two pins 11 respectively. After pressing into place, the crimping cylinder lifts the crimping parts 22, and the bottom plate removal cylinder rises. The four plate removal support pins 93 pass through the product placement table 1 to lift the machined part 12 vertically upward, making it convenient for employees to remove the product. After removing the product, the plate removal cylinder drives the plate removal support pins 93 to descend into the product placement table 1.
[0055] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
