Abstract
Description
Technical Field
[0001] This application relates to the technical field of processing equipment, and in particular to an automatic processing mechanism and a processing method for producing nail gun nail heads. Background Technology
[0002] A nail gun is a common fastening tool that uses compressed air or electric energy to drive a firing pin and quickly shoot nails into a target object. The nail head, as the front-end actuating part of the nail gun, usually has a guide groove for the nail to pass through, a positioning step for positioning, and a limiting groove to limit the nail's deviation. In order to adapt to the nail and the nail's trajectory, the circumference and end face of the nail head often need to be milled in multiple places and at multiple angles.
[0003] In the related technology, the processing mechanism includes a base, on which a feeding module and a milling module are provided. The feeding module is used to drive the nail head to move into the milling module, and the milling module is used to mill the nail head in the vertical direction.
[0004] In actual production, the guide groove of the nail head usually needs to be milled longitudinally along its axial direction (i.e., horizontal direction), while the positioning step at its end needs to be milled laterally along the end face direction (i.e., vertical direction).
[0005] Since the nail head needs to be grooved in the vertical or horizontal direction, the current automatic machining mechanism can only perform the grooving operation in one direction. Therefore, two machining mechanisms are required to process the nail head. When the same nail head needs to be grooved in the horizontal direction, the semi-finished product must be removed from the first machine and transported by manual or robotic arm to the second machine tool equipped with a horizontal milling power head for re-clamping and positioning before secondary processing. This results in low processing efficiency of the machining mechanism. Summary of the Invention
[0006] To address the issue of low processing efficiency in processing mechanisms, this application provides an automatic processing mechanism and a processing method for producing nail gun nail heads.
[0007] This application provides an automatic processing mechanism for producing nail gun heads, which adopts the following technical solution: An automated processing mechanism for producing nail gun heads includes a feeding module, a moving module, and a milling module. The feeding module drives the nail head to move into the moving module, and the moving module drives the nail head to move within the milling module. The milling module includes a first milling component and a second milling component. The first milling component performs vertical milling on the nail head, and the second milling component performs horizontal milling on the nail head. The moving module includes a moving structure and a moving table. The moving table has a placement slot for placing the nail head. The moving table is mounted on the moving structure, and the moving structure drives the moving table to move between the first and second milling components. The moving table is equipped with a moving drive component, which pushes the nail head out of the placement slot.
[0008] By adopting the above technical solution, the material is moved to the placement slot of the moving table through the feeding module. Then, the moving drive pushes the moving table between the first milling component and the second milling component. Since the first milling component and the second milling component can perform vertical and horizontal milling processing on the nail head, the nail head can meet the milling processing in different directions. This eliminates the need to replace the nail head with different processing mechanisms, thereby reducing secondary processing and improving processing efficiency.
[0009] Optionally, the moving platform is provided with an air blowing assembly, the air blowing assembly includes an air blowing pipe, the air blowing pipe is disposed in a placement groove, and the moving platform is provided with a chip removal groove communicating with the placement groove.
[0010] By adopting the above technical solution, an air blowing pipe is installed in the placement groove. When the air blowing pipe exhausts air, it can discharge the debris from the chip discharge groove, thereby reducing the debris accumulation in the placement groove and facilitating the placement of the nail head in the placement groove next time.
[0011] Optionally, the feeding module includes a feeding structure and a pushing structure. The feeding structure includes a feeding plate and a feeding drive component. The feeding plate is disposed on the feeding drive component. The feeding plate has a feeding groove for placing nail heads. The pushing structure is used to push the nail heads from the feeding groove to the placement groove.
[0012] By adopting the above technical solution, the feeding drive component moves the feeding plate, allowing the feeding slot to align with the placement slot. Then, the pushing structure moves the nail head from the feeding slot to the placement slot, realizing the feeding of the nail head. Finally, the feeding drive component drives the feeding plate to reset, allowing the nail head to be processed later to re-enter the feeding slot. Through the movement of the feeding plate, the nail head can move into the placement slot individually, allowing individual nail heads to be processed.
[0013] Optionally, the side of the feeding plate away from the ground is higher than the side of the moving platform away from the ground, and a through hole is provided on the surface of the feeding plate near the ground for the nail head to pass through.
[0014] By adopting the above technical solution, the moving drive first moves the nail head from the placement slot to the perforation point, realizing the unloading of the processed nail head. At this time, the loading drive moves the loading plate to the designated position, and the loading plate will not affect the unloading operation of the nail head. Then, the pushing structure can directly push the nail head to be processed towards the moving table, so that the nail head to be processed can be located on the side of the moving drive away from the ground. As the moving drive gradually resets, the nail head to be processed can fall smoothly into the placement slot, so that the moving drive and the loading drive can be synchronized, which can further improve the working speed and greatly reduce the waiting time required for processing.
[0015] Optionally, the moving platform is provided with a limiting block, which is located on the moving path of the nail head from the feeding trough to the placement trough; when the moving drive pushes the processed nail head away from the placement trough, the nail head to be processed is located on the side of the moving drive away from the ground.
[0016] By adopting the above technical solution, the limiting block is located on the moving path of the nail head from the feeding trough to the placement trough. The nail head abuts against the limiting block to limit the excessive movement of the nail head due to the pushing structure, so that the nail head can be stably located on the side of the moving drive component away from the ground.
[0017] Optionally, the moving drive component includes a moving drive cylinder and a moving drive bar, the moving drive bar being disposed on the moving drive cylinder, and the moving drive bar having a moving groove for placing the nail head.
[0018] By adopting the above technical solution, the nail head falls into the moving groove and can abut against the limiting block, so that the nail head can be stably placed on the moving drive bar, reducing the possibility of the nail head detaching from the moving drive bar during the movement of the moving drive bar, and allowing the nail head to move stably from the moving drive bar to the placement groove.
[0019] A processing method, S1: The finished nail head is unloaded and the nail head to be processed is moved to the designated position; the moving drive pushes the nail head from the placement slot through the through hole to achieve unloading; at the same time, the loading drive pushes the loading plate to the designated position; S2: The nail head to be processed is moved to the moving platform; the pushing structure moves the nail head from the feeding trough to the placement trough; S3: Retreat to return position; push structure and moving drive components reset, then loading drive components reset; S4: Milling operation; The first and second milling parts are used to perform milling operations on the nail head to be processed in sequence.
[0020] By adopting the above technical solution, the unloading of the processed nail head and the loading of the nail head are carried out synchronously by the moving drive component and the loading drive component. This allows the unloading operation and the movement of the loading drive component to be carried out simultaneously without interference between them, thereby speeding up the loading and unloading process and improving the efficiency of nail head production.
[0021] Optionally, S2: Simultaneous air blowing and chip removal; during the process of the pushing structure pushing the nail head, the air blowing structure simultaneously performs air blowing and chip removal operations on the moving drive bar.
[0022] By adopting the above technical solution, the blowing structure needs a certain amount of time to blow and remove chips from the drive bar. During this time, the nail head to be processed can be moved to the moving table, allowing the nail head to fall stably onto the feeding drive bar. The blowing structure can also blow and remove chips from the drive bar, so that there is no need to wait when the blowing structure removes chips later, thus further improving the efficiency of nail head production.
[0023] In summary, this application includes at least one of the following beneficial technical effects: The material is moved to the placement slot of the moving table by the feeding module. Then, the moving drive pushes the moving table between the first milling component and the second milling component. Since the first milling component and the second milling component can perform vertical and horizontal milling processing on the nail head, the nail head can meet the milling processing in different directions. This eliminates the need to change the nail head to a different processing mechanism, thereby reducing the need for secondary processing and improving processing efficiency.
[0024] First, the moving drive unit moves the nail head from the placement slot to the perforation point, completing the unloading of the processed nail head. At this time, the loading drive unit moves the loading plate to the designated position, and the loading plate does not affect the unloading operation of the nail head. Then, the pushing structure can directly push the nail head to be processed towards the moving table, so that the nail head to be processed is located on the side of the moving drive unit away from the ground. As the moving drive unit gradually resets, the nail head to be processed can fall smoothly into the placement slot, so that the moving drive unit and the loading drive unit can operate synchronously, which can further improve the working speed and greatly reduce the waiting time required for processing.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail. Example
[0028] This embodiment discloses an automated processing mechanism and a processing method for producing nail gun nail heads. (Refer to...) Figure 1 An automated processing mechanism for producing nail gun heads includes a feeding module 1, a moving module 2, and a milling module 3. The feeding module 1 drives the nail head to move into the moving module 2, the moving module 2 drives the nail head to move back and forth in the milling module 3, and the milling module 3 performs the milling process on the nail head.
[0029] Reference Figure 1 The moving module 2 includes a moving structure 21 and a moving stage 22. The moving structure 21 includes a horizontal servo motor 211 and a vertical servo motor 212. The vertical servo motor 212 is fixedly connected to the horizontal servo motor 211, and the moving stage 22 is fixedly connected to the vertical servo motor 212. The moving range of the vertical servo motor 212 and the moving range of the horizontal servo motor 211 are perpendicular to each other, realizing the horizontal and vertical movement of the moving stage 22.
[0030] Reference Figure 2 The moving platform 22 has a placement slot 221 for placing the nail head. The moving platform 22 is equipped with a moving drive component 23, which drives the nail head to disengage from the placement slot 221. The moving drive component 23 includes a moving drive cylinder 231 and a moving drive bar 232. The moving drive bar 232 is fixedly connected to the drive shaft of the moving drive cylinder 231, which is fixedly connected to the moving platform 22. The moving platform 22 has a placement hole communicating with the placement slot 221, through which the moving drive bar 232 passes.
[0031] Reference Figure 2The moving table 22 has a chip removal groove 24 on its side that connects to the placement groove 221. The moving table 22 is equipped with an air blowing assembly 241, which includes an air blowing pipe disposed in the chip removal groove 24. The air blowing pipe is used to blow the chips in the placement groove 221 and the chip removal groove 24, allowing the chips to be removed from the chip removal groove 24 for the next milling of the nail head.
[0032] Reference Figure 2 When the moving drive cylinder 231 is started, it drives the moving drive bar 232 to move within the placement groove 221, so that the nail head can be disengaged from the placement groove 221 after processing. A feeding pipe 25 is fixedly connected to the moving table 22. The feeding pipe 25 is inclined and supplies the nail head for feeding.
[0033] Reference Figure 1 and Figure 2 The feeding module 1 includes a vibratory feeder 11, a feeding structure 12, and a pushing structure 13. The feeding structure 12 includes a feeding drive component 121 and a feeding plate 122. The feeding drive component 121 includes a feeding cylinder. The feeding plate 122 has a feeding groove 123 for inserting nail heads. The feeding groove 123 extends through the width of the feeding plate 122, and the feeding plate 122 is fixedly connected to the drive shaft of the feeding cylinder. The moving path of the feeding groove 123 is located on the transmission channel of the vibratory feeder 11. When the feeding cylinder is not activated, the feeding groove 123 is aligned with the vibratory feeder 11 to achieve individual nail head feeding. The moving table 22 has a through hole 26 for inserting the feeding plate 122, and the through hole 26 is connected to the discharge pipe 25. When the feeding plate 122 is inserted into the through hole 26, the feeding groove 123 can be aligned with the placement slot 221.
[0034] Reference Figure 2 The pushing structure 13 includes a pushing cylinder 131 and a pushing bar 132. The pushing cylinder 131 is fixedly connected to the moving table 22, and the pushing bar 132 is fixedly connected to the drive shaft of the pushing cylinder 131. When the pushing cylinder 131 is activated, the pushing bar 132 can drive the nail head to be processed from the feeding groove 123 to the placement groove 221, realizing the feeding operation of the nail head.
[0035] Reference Figure 2 First, the moving drive cylinder 231 moves the moving drive bar 232, allowing the processed nail head to move from the placement groove 221 to the through hole 26. Then, when the loading drive component 121 moves the loading plate 122 to the through hole 26 of the moving table 22, the loading plate 122 pushes the nail head from the through hole 26 to the unloading pipe 25, thus realizing the unloading of the processed nail head.
[0036] Reference Figure 2First, the feeding drive unit 121 drives the feeding plate 122 to move to the through hole 26 of the moving table 22, so that the feeding groove 123 is aligned with the placement groove 221. Then, the cylinder 131 drives the push bar 132 to move, so that the push bar 132 can move the nail head to be processed from the feeding groove 123 to the placement groove 221, thereby realizing the feeding of the nail head to be processed.
[0037] Reference Figure 1 The milling module 3 includes a first milling cutter 31 and a second milling cutter 32. The first milling cutter 31 is used to mill grooves in the nail head in the vertical direction, and the second milling cutter 32 is used to mill grooves in the nail head in the horizontal direction. Both the first milling cutter 31 and the second milling cutter 32 are milling cutters. The first milling cutter 31 is placed vertically to facilitate milling grooves in the nail head. The second milling cutter 32 rotates horizontally to facilitate milling grooves in the nail head.
[0038] Reference Figure 1 and Figure 2 The movable structure 21 is used to drive the movable table 22 to move between the first milling member 31 and the second milling member 32, so that the first milling member 31 and the second milling member 32 can sequentially perform milling on the nail head.
[0039] One processing method: S1: The processed nail head is unloaded; the moving drive component 23 pushes the nail head from the placement slot 221 to the through hole 26 to realize unloading; S2: The air blowing assembly 241 blows off the chips; the air blowing pipe removes chips from the placement groove 221 and the chip removal groove 24. S3: The nail head to be processed is moved to the designated position; the feeding drive 121 pushes the feeding plate 122 to the designated position, that is, the placement groove 221 is aligned with the feeding groove 123, and the feeding plate 122 pushes the nail head from the through hole 26 to the unloading pipe 25; at the same time, the moving drive 23 is reset. S4: The nail head to be processed is loaded; the pushing structure 13 moves the nail head from the loading groove 123 to the placement groove 221; S5: Retract to the original position; push structure 13 and feeding plate 122 to reset in sequence; S6: Milling groove processing; the moving structure 21 pushes the moving table 22 to move between the first milling member 31 and the second milling member 32, so that the first milling member 31 and the second milling member 32 sequentially mill grooves the nail head.
[0040] The implementation principle of Example 1 is as follows: the moving structure 21 pushes the moving bar to move between the first milling member 31 and the second milling member 32, so that the first milling member 31 and the second milling member 32 can mill grooves on the nail head, so that the nail head does not need to be processed again. Example
[0041] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the side of the feeding plate 122 away from the ground is higher than the side of the moving platform 22 away from the ground, and a through hole 14 is provided on the surface of the feeding plate 122 near the ground, through the nail head through the through hole 14, and through the through hole 14 extends to the surface of the feeding plate 122 away from the feeding cylinder.
[0042] Reference Figure 3 and Figure 4 A limiting block 27 is fixedly connected to the surface of the moving platform 22 away from the ground. The limiting block 27 is located on the moving path of the nail head from the feeding trough 123 to the placement trough 221. A moving groove 271 for inserting the nail head is opened on the surface of the moving drive bar 232 away from the ground. The moving groove 271 is inclined, and the distance between the bottom wall of the moving groove 271 and the ground gradually increases along the direction from the moving drive cylinder 231 to the moving drive bar 232.
[0043] Reference Figure 4 A stop spring 272 is fixedly connected to the wall of the placement groove 221, and a stop strip 273 is fixedly connected to the stop spring 272. The stop spring 272 drives the stop strip 273 to partially block the opening of the placement groove 221 away from the ground. When the moving drive strip 232 moves into the placement groove 221, the moving drive strip 232 pushes the stop strip 273 to move in the direction of the stop spring 272, so that the stop strip 273 does not partially block the opening of the placement groove 221 away from the ground; when the moving drive strip 232 returns to its original position, the stop spring 272 drives the stop strip 273 to move, so that the stop strip 273 can restrict the movement of the nail head in the placement groove 221.
[0044] Reference Figure 4 First, the moving drive cylinder 231 drives the moving drive bar 232 to move, so that the moving drive bar 232 moves the processed nail head from the placement groove 221 to the through hole 26; at the same time, the feeding drive component 121 pushes the feeding plate 122 to move, so that the feeding plate 122 can move to the through hole 26, so that the through hole 14 is aligned with the placement groove 221. Since the through hole 14 on the feeding plate 122 will not affect the moving drive bar 232; as the processed nail head accumulates in the through hole 26, the feeding plate 122 can push a part of the nail head out of the unloading pipe 25.
[0045] Reference Figure 4The cylinder 131 is pushed to move the push bar 132, which in turn moves the nail head to be processed from the loading groove 123 to the side of the moving drive bar 232 away from the ground. This ensures that the nail head is located in the moving groove 271, with one end of the nail head abutting the limiting block 27 to limit excessive movement of the nail head. At the same time, the air blowing pipe can blow air to the moving drive bar 232 to remove chips. Afterward, the moving drive bar 232 and the push bar 132 are reset synchronously, allowing the moving drive bar 232 to move the nail head into the placement groove 221.
[0046] A processing method, S1: The processed nail head is unloaded and the nail head to be processed is moved to the designated position; the moving drive cylinder 231 pushes the processed nail head from the placement groove 221 to the through hole 26; at the same time, the loading drive component 121 pushes the loading plate 122 to the designated position, that is, the loading plate 122 moves to the through hole 26, so that the through hole 14 is aligned with the placement groove 221; S2: The nail head to be processed is moved to the moving table 22 and blown to remove chips; the push cylinder 131 drives the push bar 132 to move the nail head from the loading groove 123 to the side of the moving drive bar 232 away from the ground, so that the nail head can be located in the moving groove 271; at the same time, the air blowing pipe can blow air to remove chips in the placement groove 221. S3: Reset to position; Push bar 132 and moving drive bar 232 reset simultaneously. At this time, the moving drive bar 232 drives the nail head to move. The nail head is restricted by the limiting block 27, so that the nail head can fall smoothly into the placement slot 221. As the moving drive bar 232 is fully reset, the stop spring 272 drives the stop bar 273 to move, so that the stop bar 273 can partially block the placement slot 221, thereby limiting the nail head; then the feeding drive component 121 resets. S4: Milling groove processing; the moving structure 21 pushes the moving table 22 to move between the first milling member 31 and the second milling member 32, so that the first milling member 31 and the second milling member 32 sequentially mill grooves the nail head.
[0047] The implementation principle of Example 2 is as follows: by simultaneously unloading the processed nail head and moving the nail head to be processed to the designated position, the original processing method is reduced from six steps to four steps, which greatly improves the production speed.
