A three-station drilling and nailing machine

Abstract

This invention discloses a three-station drilling and nailing machine, specifically relating to the field of integrated nail production technology. It includes a base, with a housing fixedly connected to the upper end of the base. A lifting mechanism is provided at the upper end of the base, a guide component is provided below the lifting mechanism, a feeding component is provided to the left of the guide component, and a nailing component is provided to the right of the feeding component. A limiting component is provided above the nailing component. This invention ensures complete alignment of the three pads with the drilling device and allows the drilling during the descent phase to be connected to the nailing during the ascent phase via the lifting stroke of the lifting mechanism. This transforms drilling and nailing from multi-step, dispersed operations into a single-step, continuous operation. When the nailing component lifts the integrated nail, the limiting component simultaneously presses down on the pads to prevent the pads from lifting and causing the integrated nail to become misaligned. Subsequent descent involves the feeding component completing the process of removing the finished product and placing the new material, thus improving the overall continuous operation capability.

Description

Technical Field

[0001] This invention relates to the field of integrated nail production technology, and in particular to a three-station drilling and nailing machine. Background Technology

[0002] In the field of integrated nail production technology, the stable connection between integrated nails and washers is a core process in the manufacturing of products in many fields, including hardware accessories, automotive fasteners, home appliance connectors, agricultural machinery parts, and electronic equipment terminals. These products often need to withstand vibration, pressure, or long-term loads during use. If the connection is loose, it can easily cause equipment failure or even safety hazards. Therefore, the connection strength and stability of integrated nails and washers are required to be extremely high. Existing integrated nail and washer connection technologies have significant shortcomings. Most equipment uses a single station, resulting in low batch production efficiency. Drilling and nailing are often separated into independent processes, requiring manual transfer of workpieces or equipment switching. Secondary positioning can easily lead to deviations between hole and nail positions, affecting connection accuracy. Some equipment relies on manual loading and unloading, which not only increases labor costs but also easily causes workpiece scrap due to operational errors. A few integrated equipment have problems such as uneven pressure of limiters and unstable nailing firmness, making it difficult to meet the production requirements of high-precision and high-consistency integrated nail components. Summary of the Invention

[0009] Preferably, the nailing assembly includes two connecting frames fixedly connected to the lower end of the lifting plate, two springs are fixedly connected to the upper end of the base, a connecting plate is fixedly connected to the upper end of the two springs, a fixing plate is fixedly connected to both the front and rear ends of the connecting plate, three support columns are fixedly connected to the upper end of the connecting plate, a top block is fixedly connected to the upper end of each of the three support columns, the center of the three top blocks is aligned with the center of the three through slots, the center of the three through slots is aligned with the center of the three slots on the right side, and the outer surface of the three top blocks is slidably connected to the through slots and slots at the appropriate positions.

[0010] Preferably, the limiting component includes a rack 1 fixedly connected to the two connecting frames on opposite sides, gears meshing with the left sides of both racks 1, support blocks fixedly connected to the front and rear sides of the upper end of the base, the ends of the two support blocks rotatably connected to the gears on the same side, rack 2 meshing with the left sides of both gears, a shaped frame fixedly connected to the adjacent sides of the two racks 2, spring 2 fixedly connected to the front and rear sides of the lower end of the shaped frame, the lower ends of the two spring 2 fixedly connected to the upper end of the base, and three annular cylinders fixedly connected to the upper end of the shaped frame, the centroids of the three annular cylinders corresponding to the centroids of the three processing grooves respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes the guiding effect of the guide groove to ensure that the three shims are completely aligned with the drilling device. It also connects the drilling in the descent stage with the nailing in the ascending stage through the lifting stroke of the lifting mechanism, transforming drilling and nailing from multi-step, decentralized operations into a single-step, continuous operation. Furthermore, when the nailing component lifts the integrated nail, the limiting component simultaneously presses the shims downward to prevent the shims from lifting and causing the integrated nail to become skewed during nailing. Subsequently, the descent is completed by the feeding component to remove the finished product and place the new material. Overall, it significantly improves continuous operation capability, greatly enhances batch efficiency, and adapts to the needs of large-scale production. This invention utilizes the guiding function of the guide groove to allow the lifting plate to punch holes in the gasket during its lifting process, while also shifting the processing table to adjust the position of the gasket during different processes. Furthermore, the lifting plate's ascent synchronously connects the gasket to the integrated nail, and the limiting block restricts the gasket's position, preventing misaligned nailing and saving extra time spent switching workstations. This allows for smoother transitions between two processes. The loading and limiting components work together to achieve the descent, removing the finished product and placing the new material. The overall three-station design allows three workpieces to be processed per lifting and loading / unloading cycle, significantly improving batch efficiency and fully adapting to the needs of large-scale production.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figure 1-5 As shown, a three-station drilling and nailing machine includes a base 1. The upper end of the base 1 has two through slots 11. The lower end of the base 1 is provided with a feeding cylinder 12. The upper end of the base 1 is fixedly connected to an outer shell 13. The upper end of the base 1 is provided with a lifting mechanism 2. The lower side of the lifting mechanism 2 is provided with a guide component 3. The guide component 3 includes a guide groove 32 and a processing table 37. The left side of the guide component 3 is provided with a feeding component 4. The right side of the feeding component 4 is provided with a nailing component 5. The upper side of the nailing component 5 is provided with a limit component 6. During the lifting process, the lifting mechanism 2 can drive the processing table 37 to move through the guide groove 32, and can also drive the nailing component 5 to drive the integrated nail into the pad. The left side of the feeding component 4 is provided with a loading component 7.

[0019] During the operation of this embodiment, the guiding effect of the guide groove 32 ensures that the three shims are fully aligned with the drilling device 24. The lifting mechanism 2 can also connect the drilling in the lowering stage with the nailing in the rising stage through the lifting stroke, so that drilling and nailing are transformed from multi-step scattered operations into single-step continuous operations. When the nailing component 5 lifts the integrated nail, the limiting component 6 presses the shims downward simultaneously to prevent the shims from lifting and causing the integrated nail to become crooked during nailing. Then, when it descends again, the feeding component 7 completes the process of removing the finished product and placing the new material. Overall, the continuous operation capability is greatly improved, the batch efficiency is significantly improved, and it is suitable for the needs of large-scale production.

[0020] Example 2: Based on Example 1, this example aims to achieve the drilling of the gasket and the connection between the gasket and the integral nail in a single lifting motion.

[0021] like Figure 1-5 and Figure 9 The lifting mechanism 2 includes a fixed base 21 fixedly connected to the upper end of the base 1. A hydraulic device 22 is fixedly installed on the upper end of the fixed base 21. A lifting plate 23 is fixedly connected to the output end of the hydraulic device 22. Three drilling devices 24 are fixedly installed on the lower end of the lifting plate 23.

[0022] The drilling device 24 described above is existing technology. Its internal motor drives the drill bit to start rotating at high speed. At the same time, the lifting plate 23 drives the three drilling devices 24 to feed vertically downward at a controlled, slower speed. When the rotating drill bit contacts the surface of the pad, its sharp cutting edge cuts the metal material layer by layer, forming curled chips, and finally penetrates the pad to form a complete hole.

[0023] like Figure 3-7 The guide assembly 3 includes two connecting seats 31 fixedly connected to the right side of the lifting plate 23. The outer surfaces of the two connecting seats 31 are provided with guide grooves 32. Support seats 33 are fixedly connected to the front and rear sides of the upper end of the base 1. Rotating shafts 34 are rotatably connected to the inner surfaces of the two support seats 33. Rotating arms 341 and 342 are fixedly connected to the outer surfaces of the two rotating shafts 34. The rear side of the rotating arms 342 is slidably connected to the guide grooves 32. Limiting shafts 35 are slidably connected to the inner surfaces of the two rotating arms 341. Movable seats 36 are fixedly connected to the ends of the two limiting shafts 35 that are close to each other. Sliding guide rails 361 are fixedly connected to the front and rear sides of the feed cylinder 12. The lower ends of the two movable seats 36 are slidably connected to the sliding guide rails 361 on the same side.

[0024] The upper ends of the two movable seats 36 are fixedly connected to the processing table 37. The upper end of the processing table 37 is provided with three processing slots 371. The inner surface of each of the three processing slots 371 is provided with a through slot 372. The arc-shaped part of each of the three processing slots 371 is equipped with a magnetic block 373.

[0025] Furthermore, the guide groove 32 mentioned above consists of two vertical parts and one horizontal part, which divides the lifting of the lifting plate 23 into three strokes. The horizontal part of the groove is mainly used to drive the processing table 37 to move horizontally left and right. After drilling is completed, the processing table 37 can automatically return to the left side, freeing up operating space for subsequent nailing and loading / unloading processes, realizing the isolation between the drilling area and the nailing and loading / unloading areas, and avoiding mutual obstruction between different processes in the same space.

[0026] Furthermore, each of the three drilling devices 24 is equipped with a limiting mechanism, specifically an elastic annular pressure plate. When the drilling device 24 is about to contact the gasket, the limiting mechanism will press and limit the gasket in advance.

[0027] The magnetic block 373 has a lateral attraction and guiding effect on the ferromagnetic pad. When the pad enters the processing groove 371, it will immediately enter the effective magnetic field range of the magnetic block 373 pre-embedded inside the arc side wall. This magnetic field will instantly attract the pad. Under the action of this attraction, the outer edge of the pad will overcome its own gravity and motion inertia and instantly stick tightly to the arc-shaped inner wall of the processing groove 371. Even if the position of the pad is slightly deviated when it enters the processing groove 371, the magnetic force can automatically pull it to the correct position, playing a role in flexible guidance and final positioning.

[0028] Then, the hydraulic device 22 and the drilling device 24 are started. The hydraulic device 22 drives the lifting plate 23, the connecting seat 31 and the guide groove 32 to descend. During the process, the rotating arm 2 342 will first slide on the vertical part on the left side of the guide groove 32. Then, when the rotating arm 2 342 moves to the horizontal part of the guide groove 32, it will be pulled to tilt during the movement, thereby driving the rotating arm 1 341 on one side to lift up simultaneously, thereby pulling the moving seat 36 and the processing table 37 to move to the right as a whole. When the rotating arm 2 342 moves to the rightmost end of the horizontal part of the guide groove 32, the moving seat 36 and the processing table 37 just move to the bottom of the lifting plate 23. In this state, the center points of the arc-shaped parts of the three processing grooves 371 are aligned with the center points of the three drilling devices 24 on the upper side. Subsequently, the hydraulic device 22 continues to drive the lifting plate 23 to continue to descend, so that the drilling device 24 drills holes in the gasket placed in the processing groove 371. In this state, the rotating arm 342 will slide on the vertical part on the right side of the guide groove 32.

[0029] like Figure 5 and Figure 8 The feeding assembly 4 includes a fixed base 2 41 fixedly connected to the upper end of the base 1. A fixed disc 411 is fixedly connected to the upper end of the fixed base 2 41. Three through slots 3 412 adapted to the integral nail are opened on the right side of the fixed base 2 41. A feeding turntable 42 is rotatably connected to the upper end of the fixed disc 411. The outer surface of the feeding turntable 42 has six slots arranged in a ring to limit the integral nail. The center of the three slots near the moving base 36 is aligned with the center of the arc-shaped part of the three processing slots 371 respectively.

[0030] When the aforementioned feeding turntable 42 is stationary, the three slots on its left side align with the integrated nail conveying mechanism 72 on the left side. The three integrated nails conveyed by the three integrated nail conveying mechanisms 72 are directly placed into these three slots, relying on their own weight and the constraint of the hole walls to ensure stable standing. On the three slots at the right end of the feeding turntable 42, the three integrated nails placed in the previous round can be pressed and connected with the shims. When the actions on both sides are completed, the feeding turntable 42 will rotate 180 degrees, accurately delivering the set of nails that has just been placed to the work station. At the same time, the empty positioning hole immediately begins to receive a new batch of integrated nails. This is a conventional technical field in the prior art, so it will not be described in detail in this solution.

[0031] like Figure 8-10 The nailing assembly 5 includes two connecting brackets 51 fixedly connected to the lower end of the lifting plate 23. Two springs 52 are fixedly connected to the upper end of the base 1. A connecting plate 53 is fixedly connected to the upper end of the two springs 52. Fixed plates 54 are fixedly connected to both the front and rear ends of the connecting plate 53. Three support columns 55 are fixedly connected to the upper end of the connecting plate 53. Top blocks 56 are fixedly connected to the upper ends of the three support columns 55. The center of the three top blocks 56 is aligned with the center of the three through slots 412. The center of the three through slots 412 is aligned with the center of the three slots on the right side. The outer surface of the three top blocks 56 is slidably connected to the through slots 412 and slots at the appropriate positions.

[0032] Furthermore, the spring 52 mentioned above can provide elastic support for the entire connecting plate 53. Without the pulling of the connecting frame 51, the spring 52 supports the connecting plate 53, the support column 55 and the top block 56, so that the upper end of the top block 56 is on the same horizontal line as the upper end of the fixed disc 411. Therefore, when the feeding turntable 42 drives the integrated nail to rotate to the through slot 412, the top block 56 will hold the lower end of the suspended integrated nail. The distance that the top block 56 rises and falls is equal to the distance of the vertical part on the right side of the guide groove 32. When the lifting plate 23 just begins to fall, the rotating arm 342 is located at the vertical part on the right end of the guide groove 32. This part of the stroke is mainly to allow the top block 56, support column 55 and connecting plate 53 and other structures to fall first, so that the corresponding annular cylinder 67 rises simultaneously, releasing the limit on the installed integrated nail, which is convenient for the subsequent cutting of the integrated nail.

[0033] Subsequently, after the three gaskets are drilled, the hydraulic device 22 drives the lifting plate 23 to rise. When the rotating arm 342 moves from the upper right end of the guide groove 32 to the left side of the horizontal part of the rotating arm 342, the moving seat 36 and the processing table 37 return to their initial positions. In this state, the center point of the gasket, the slot on the surface of the feeding turntable 42, and the three through slots 412 on the lower side are all on the same vertical line. At this time, the lifting plate 23 drives the connecting seat 31 to continue to rise, and the rotating arm 342 moves to the vertical part on the left side of the guide groove 32. In this state, the lower end of the inner surface of the connecting frame 51 will contact the fixing plate 54 and pull the fixing plate 54 to lift it up. Simultaneously, the connecting plate 53, the support column 55, and the top block 56 rise synchronously. The three fixing plates 54 can push the integrated nails at the corresponding positions from the bottom up and drive the integrated nails into the center hole of the gasket at the corresponding position for connection.

[0034] like Figure 10-11 The limiting component 6 includes a rack 61 fixedly connected to the two connecting frames 51 on opposite sides. Gears 63 are meshed on the left sides of the two racks 61. Support blocks 62 are fixedly connected to the front and rear sides of the upper end of the base 1. The ends of the two support blocks 62 that are close to each other are rotatably connected to the gears 63 on the same side. A rack 64 is meshed on the left sides of the two gears 63. A shaped frame 65 is fixedly connected to the side of the two racks 64 that are close to each other. Springs 66 are fixedly connected to the front and rear sides of the lower end of the shaped frame 65. The lower ends of the two springs 66 are fixedly connected to the upper end of the base 1. Three annular cylinders 67 are fixedly connected to the upper end of the shaped frame 65. The centroids of the three annular cylinders 67 correspond to the centroids of the three processing grooves 371, and the centroids are the shape centers.

[0035] The lower ends of the three annular cylinders 67 are each arranged in a ring with four springs 671, and the lower ends of the four springs 671 on the same side are fixedly connected to the limiting block 672.

[0036] Spring 66 is mainly used to provide support for the irregular frame 65, so that the irregular frame 65 drives rack 64 to always be engaged with gear 63 and will not disengage. Spring 671 is for providing cushioning. Even if the limit block 672 has contacted and limited the pad, rack 61, gear 63 and rack 64 can still mesh and move a distance, so that the fixing plate 54 can drive the three integral nails into the center holes of the three corresponding pads respectively.

[0037] Furthermore, the distance by which the annular cylinder 67 descends or rises is equal to the distance between the switch 77 and the contact block 78.

[0038] Furthermore, as the connecting frame 51 drives the fixing plate 54 to rise, rack 61 rises synchronously, meshing with gear 63 and rack 64, simultaneously driving the two racks 64 to descend, thereby driving the irregular frame 65 and the three annular cylinders 67 to descend. During this process, the limiting block 672 will contact the pad in advance to press it down. Subsequently, the integrated nail is driven upward by the top block 56 and driven into the center hole of the pad. This can prevent the pad from tilting during the nailing process, causing the nail to be crooked, and can also provide a stable downward pressure reaction force for the integrated nail, ensuring that the nail is completely driven into the hole and avoiding insecure nailing.

[0039] At this time, the lifting plate 23 has risen to the top. Then the hydraulic device 22 drives the lifting plate 23 to fall again. As the rotating arm 342 moves in the vertical part on the right side of the guide groove 32, the fixed plate 54 loses tension due to the descent of the connecting frame 51. The fixed plate 54 will also fall synchronously, thereby causing the irregular frame 65 on one side to rise. This releases the three annular cylinders 67 from the limit of the connected integrated nail. At the same time, the top block 56 also disengages from the three slots on the right side of the feeding turntable 42.

[0040] like Figure 2 , Figure 6 , Figure 7 and Figure 11 The feeding assembly 7 includes three pad feeding mechanisms 71 and three integrated nail conveying mechanisms 72. An electric telescopic rod 73 is fixedly installed on the left side of the upper end of the processing table 37. A push rod 74 is fixedly installed at the output end of the electric telescopic rod 73. The lower end of the push rod 74 is slidably connected to the processing table 37. A switch 1 75 is installed on the upper end of the processing table 37. A fixing block 76 is fixedly connected to the front side of the upper end of the base 1. A switch 2 77 is installed on the upper end of the rear side of the fixing block 76. A touch block 78 is fixedly connected to the front end of the irregular frame 65.

[0041] The touch block 78 is movably connected to switch 2 77, the lower end of push rod 74 is slidably connected to switch 1 75, switch 2 77 is electrically connected to electric telescopic rod 73, and switch 1 75 is electrically connected to gasket feeding mechanism 71 and feeding turntable 42. Electric telescopic rod 73 is electrically connected to each other.

[0042] Furthermore, the gasket feeding mechanism 71 and the integrated nail conveying mechanism 72, respectively, are connected to an external feeding mechanism at the ends away from the feeding component 4, which are both conventional technical fields in the prior art.

[0043] Furthermore, during the ascent of the irregular frame 65, the contact block 78 will touch the switch 2 77, thereby triggering the electric telescopic rod 73 to drive the push rod 74, quickly pushing the three installed integrated nails into the unloading cylinder 12. When the push rod 74 moves to the rightmost end of the processing table 37, it will touch the switch 1 75. The switch 1 75 will quickly activate the gasket feeding mechanism 71 and the feeding turntable 42. The feeding turntable 42 will rotate 180 degrees, so that the integrated nail body on the integrated nail conveying mechanism 72 enters the slot on the left side of the feeding turntable 42. The gasket feeding mechanism 71 will move forward a bit, allowing the gasket to fall into the processing groove 371. The gasket will be attracted by the magnetism of the magnetic block 373, making it stick tightly to the arc surface of the processing groove 371.

[0044] Specifically, when the touch block 78 moves to the predetermined position and touches the second switch 77, it will close a circuit and send an input signal to the PLC. After receiving this signal, the PLC will immediately send an output signal to the electric telescopic rod 73 according to the preset program. After the electric telescopic rod 73 is powered on, it drives the push rod 74 to start moving. Next, when push rod 74 moves to the rightmost end and touches switch 75, the PLC receives a second input signal. This signal triggers the next logic step in the PLC program, which sends electrical signals to three output terminals simultaneously within the same processing cycle: one signal is sent to the actuator cylinder of the gasket feeding mechanism 71 to move the gasket on its conveyor belt, and another signal is sent to the motor driver of the feeding turntable 42 to command it to rotate 180 degrees; a timer preset to 2 seconds is started. During this 2-second delay, the gasket feeding mechanism 71 can transport the gasket to the surface of the processing groove 371. When the timer inside the PLC finishes counting down, the PLC will reverse the signal to the electric telescopic rod 73, causing push rod 74 to automatically return to its initial position from the rightmost end. This is a conventional technical means in the prior art, so it will not be described in detail in this solution.

[0045] Therefore, this solution, through the guiding action of the guide groove 32, allows the lifting plate 23 to punch holes in the gasket using the drilling device 24 during the lifting process, and also allows the processing table 37 to shift, thereby adjusting the position of the gasket during different processes. Furthermore, the lifting plate 23 can simultaneously connect the gasket to the integrated nail and limit the gasket with the limiting block 672, eliminating the problem of mis-drilling nails, saving extra time for station switching, and making the connection between two processes smoother. In this process, the loading component 7 and the limiting component 6 work together to complete the descent, i.e., the removal of finished products and the placement of new materials. The overall three-station design allows three workpieces to be processed each time the lifting and loading / unloading are carried out, significantly improving batch efficiency and fully adapting to the needs of large-scale production.
