Description

Technical Field

[0001] The present application relates to a pen tip processing device, and in particular to a pen tip drilling device. Background Art

[0002] Water-based pens typically use metal nibs, and drilling is a critical step in the process. This process involves creating a hole in the nib to facilitate the installation of the ink cartridge and ensure smooth ink flow. These nibs are typically made of high-strength, corrosion-resistant stainless steel. This material offers excellent mechanical properties and durability, making it suitable for withstanding the significant stresses encountered during writing.

[0003] In the related art, during the drilling process, the metal pen tip needs to be fixed on a drill press or drilling machine, and the drill bit needs to be aligned with the predetermined position; then, by rotating the drill bit and applying downward pressure, the drill bit cuts the metal to form the required hole diameter and depth; during the drilling process, the cutting speed, cutting lubricant and cutting force need to be controlled to ensure the hole size and quality.

[0004] However, since the diameter of the metal pen core is small, the diameter of the drilled hole also needs to be correspondingly small, which means that the drilling accuracy requirements are higher and more careful positioning and clamping are required to ensure the accuracy and precision of the drilling position. This requires the operator to spend more time and attention to adjust and correct the clamping position, which is more cumbersome. It also leads to low drilling efficiency of the metal pen tip, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a pen tip drilling device to solve the problem in the above-mentioned related technology that since the diameter of the metal pen core is small, the diameter of the drilled hole also needs to be correspondingly smaller, which means that the drilling accuracy requirements are higher and more careful positioning and clamping are required to ensure the accuracy and precision of the drilling position. This requires the operator to spend more time and attention to adjust and correct the clamping position, which is more cumbersome and also leads to the problem of low drilling efficiency of the metal pen tip.

[0006] The present application provides a pen tip drilling device that adopts the following technical solution:

[0007] A pen tip drilling device includes a processing table, a rotating disk and a driving member for driving the rotating disk to rotate are provided on the processing table, a drilling assembly is provided above the rotating disk, and a plurality of limiting holes are provided on the rotating disk; a fixed disk is provided below the rotating disk on the processing table, and a feed hole and a discharge hole are provided on the fixed disk, which can respectively coincide with the limiting holes; a feed assembly for moving the metal pen tip through the feed hole to the inside of the limiting hole is provided on the side of the processing table, and a clamping assembly for clamping the metal pen tip is provided on the inner wall of the limiting hole.

[0008] By adopting the above technical solution, when drilling processing is required, the metal pen tip is first moved to the inside of the limiting hole through the feeding assembly and clamped by the clamping assembly, and then the driving member drives the rotating disk to rotate, and the metal pen tip inside the limiting hole is rotated to the bottom of the drilling assembly. After the drilling assembly completes drilling the metal pen tip in the limiting hole, the rotating disk continues to rotate, so that the limiting hole and the discharge hole coincide, so that the metal pen tip processed in the limiting hole is removed from the discharge hole. After the metal pen tip enters the limiting hole, it is directly clamped by the clamping assembly, thereby facilitating the drilling processing of the metal pen tip, reducing the time required for clamping the metal pen tip, and improving the processing efficiency of the metal pen tip.

[0009] Optionally, the feeding assembly includes a vibrating plate and a discharge pipe connected to the vibrating plate. The side of the discharge pipe is connected to a partition for allowing the metal pen tip inside the discharge pipe to be transmitted at intervals. The end of the discharge pipe away from the vibrating plate is located below the feed hole on the fixed plate. The side of the discharge pipe is provided with a power part for allowing the metal pen tip in the discharge pipe to pass through the feed hole and enter the limiting hole.

[0010] By adopting the above technical solution, when the metal pen tip moves to the inside of the limiting hole on the rotating disk through the feeding assembly, the metal pen tip is placed in the inside of the vibration disk in advance, and the metal pen tip is transferred to the inside of the discharge pipe through the vibration disk. The separator causes the metal pen tip inside the discharge pipe to be transferred at intervals, and the power component causes the metal pen tip in the discharge pipe to pass through the feeding hole and enter the inside of the limiting hole, thereby realizing the feeding process of the metal pen tip.

[0011] Optionally, the separator is a first motor fixed to the side of the processing table, a first baffle and a second baffle fixed to the output shaft of the first motor, a first blocking groove for the first baffle to be inserted and moved back and forth is provided on the discharge pipe, and a second blocking groove for the second baffle to be inserted and moved back and forth is provided on the discharge pipe; when one of the first baffle and the second baffle blocks the discharge pipe, the other opens the discharge pipe.

[0012] By adopting the above technical solution, when one of the first baffle and the second baffle blocks the discharge pipe, the other opens the discharge pipe; when the first baffle is rotated out from the inside of the first barrier groove, the second baffle blocks the discharge pipe, so that each corresponding metal pen tip is transported to the corresponding limiting hole in an orderly manner after a certain period of time, reducing the possibility of the metal pen tip being blocked at the opening of the discharge pipe during feeding.

[0013] Optionally, the power component includes a first air pump and a first air pipe connected to the first air pump, and the end of the first air pipe away from the first air pump is connected to the outer side surface of the discharge pipe.

[0014] By adopting the above-mentioned technical solution, the first air pump can supply compressed gas to the discharge pipe near the rotating disk part through the first air pipe. In this way, the metal pen tip inside the discharge pipe near the rotating disk part is moved to the inside of the limiting hole through the impact force of the compressed gas, thereby realizing the operation of moving the metal pen tip from the inside of the discharge pipe to the inside of the limiting hole.

[0015] Optionally, the drilling assembly includes a drill bit and a power source located above a certain limiting hole, and the power source is used to drive the drill bit to operate and move up and down.

[0016] By adopting the above technical solution, when a drilling assembly is needed to perform drilling processing, the drill bit is driven by a power source to enable the drill bit to perform a drilling operation on the metal pen tip located below the drill bit.

[0017] Optionally, a placement groove is provided on the inner wall of the limiting hole, and the clamping assembly includes two arc-shaped limiting plates arranged opposite to each other and hinged to the inner wall of the placement groove, an arc-shaped clamping plate is provided on one side of the arc-shaped limiting plate, and a guide plate extending to the outside of the bottom side of the placement groove is fixed on the side of the arc-shaped limiting plate away from the arc-shaped clamping plate, and a first annular guide groove and a second annular guide groove are provided on the fixed plate for the two guide plates to be inserted and rotated respectively; the bottom sides of the first annular guide groove and the second annular guide groove are provided with an abutment portion located below the drill bit, and when the guide plate is tightly pressed against the abutment portion, the arc-shaped limiting plate rotates and clamps the arc-shaped clamping plate and the outer peripheral surface of the metal pen tip.

[0018] By adopting the above technical solution, due to the setting of the clamping assembly, when the arc-shaped clamping plate is not tightly abutted against the abutting portion, due to the influence of the arc-shaped limiting plate's own gravity, the arc-shaped limiting plate simply clamps the metal pen tip to prevent the metal pen tip from falling off from the bottom of the limiting hole; when the limiting hole with the metal pen tip is rotated to the bottom of the drill bit, due to the setting of the abutting portion, the arc-shaped clamping plate is clamped to the outer peripheral surface of the metal pen tip, and a simpler structure is used to achieve a clamping operation away from the inside of the limiting hole, thereby reducing the possibility of the metal pen tip loosening or offsetting inside the limiting hole when the drill bit is drilling.

[0019] Optionally, arc-shaped protrusions are provided on the adjacent sides of the two arc-shaped limiting plates.

[0020] By adopting the above technical solution, when the arc-shaped limiting plate is used to clamp the metal pen tip inside the limiting hole, the setting of the arc-shaped protrusion further reduces the possibility of the metal pen tip escaping from the lower opening of the limiting hole at this time, thereby improving the installation stability of the metal pen tip inside the limiting hole.

[0021] Optionally, a first magnetic member is provided on the two arc-shaped limiting plates, and a second magnetic member that attracts the first magnetic member is provided on the inner walls of the first annular guide groove and the second annular guide groove.

[0022] By adopting the above-mentioned technical solution, when the two guide plates rotate respectively inside the first annular guide groove and the second annular guide groove, due to the mutual attraction between the first magnetic part and the second magnetic part, the possibility of the arc-shaped limiting plate rotating around the hinge axis in a natural state is reduced, so that the side surface of the arc-shaped limiting plate is tightly pressed against the outer peripheral surface of the metal pen tip, and at the same time, the installation stability of the metal pen tip inside the limiting hole is further improved.

[0023] Optionally, the processing table is provided with a third air pipe located above the discharge hole and a driving source for supplying compressed air to the third air pipe, and the third air pipe is provided with a third control valve for controlling its own on and off.

[0024] By adopting the above technical solution, when the processed metal pen tip rotates to a position that coincides with the discharge hole, the driving source is started and the third control valve is opened. The impact of compressed gas overcomes the limit of the metal pen tip by the clothing clip assembly, so that the processed metal pen tip is detached from the lower opening of the discharge hole, thereby realizing the discharge of the metal pen tip.

[0025] Optionally, the fixed plate is provided with a detection hole located between the abutment portion and the discharge hole and capable of coinciding with the limiting hole, and the processing table is provided with a detection assembly; the detection assembly includes a sensor located above the detection hole and a second air pipe, and the driving source is also used to supply the compressed air required by the second air pipe, and the second air pipe is provided with a second control valve for controlling its own on and off.

[0026] By adopting the above technical solution, the metal pen tip that has been drilled continues to rotate to the bottom of the sensor along with the rotating disk. When the sensor detects that the processing of the metal pen tip does not meet the standards, the driving source is started and the second control valve is opened, and the second air pipe is used to discharge the metal pen tip inside the limit hole from the lower opening of the detection hole; when the sensor detects that the drilling of the metal pen tip meets the standards, the rotating disk continues to rotate, and the metal pen tip that has passed the inspection is rotated to the bottom of the discharge hole, completing its discharge process.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When drilling is required, first move the metal pen tip to the inside of the limiting hole through the feeding assembly and clamp it through the clamping assembly. Then, the driving member drives the rotating disk to rotate and rotate the metal pen tip inside the limiting hole to the bottom of the drilling assembly. After the drilling assembly completes drilling the metal pen tip in the limiting hole, the rotating disk continues to rotate to make the limiting hole coincide with the discharge hole, so that the metal pen tip processed in the limiting hole is removed from the discharge hole. After the metal pen tip enters the limiting hole, it is directly clamped by the clamping assembly, thereby facilitating the drilling of the metal pen tip, reducing the time required for clamping the metal pen tip, and improving the processing efficiency of the metal pen tip.

[0029] 2. Due to the setting of the clamping assembly, when the arc-shaped clamping plate is not tightly abutted against the abutting part, due to the influence of the arc-shaped limiting plate's own gravity, the arc-shaped limiting plate simply clamps the metal pen tip to prevent the metal pen tip from falling off from the bottom of the limiting hole; when the limiting hole with the metal pen tip is rotated to the bottom of the drill bit, due to the setting of the abutting part, the arc-shaped clamping plate is clamped to the outer peripheral surface of the metal pen tip, and a simpler structure is used to achieve a clamping operation away from the inside of the limiting hole, thereby reducing the possibility of the metal pen tip loosening or offsetting inside the limiting hole when the drill bit is drilling.

[0049] Reference Figure 2The power part 34 includes a first air pump 341 fixed on the side of the processing table 1 and a first air pipe 342 connected to the first air pump 341, wherein the end of the first air pipe 342 away from the first air pump 341 is connected to the outer side of the discharge pipe 32, and the first air pipe 342 is provided with a first control valve 343 for controlling its own opening and closing. The first control valve 343 is an electromagnetic valve. The first air pump 341 can supply compressed gas to the discharge pipe 32 near the rotating disk 11 through the first air pipe 342. With this arrangement, the metal pen tip inside the discharge pipe 32 near the rotating disk 11 is moved to the inside of the limiting hole 111.

[0050] Reference Figure 5 The drilling assembly 2 includes a drill bit 22 and a power source 21 located above a certain limit hole 111. The power source 21 is used to drive the drill bit 22 to operate and move up and down; a support arm 14 is fixedly provided on the processing table 1, and a slider 141 that can slide up and down is provided on the support arm 14. The power source 21 includes a second motor 211, a driving screw 212 and a third motor 213. The up and down sliding of the slider 141 is achieved by the cooperation of the second motor 211 and the driving screw 212. This is a conventional means and will not be repeated here. The third motor 213 is fixed to the lower side of the slider 141, and the output shaft of the second motor 211 is coaxially fixedly connected to the drill bit 22, so as to realize the rotation of the drill bit 22 and the up and down movement of the drill bit 22.

[0051] Reference Figure 2 and Figure 3 The clamping assembly 4 includes two arc-shaped limiting plates 41 located inside the limiting hole 111 and arranged opposite to each other, and an arc-shaped clamping plate 42 is welded and fixed on one side of the arc-shaped limiting plate 41. A placement groove 112 is provided on the inner wall of the limiting hole 111, and the connection between the two arc-shaped limiting plates 41 and the corresponding arc-shaped clamping plates 42 is hinged to the inner wall of the placement groove 112 through a hinge axis; the side of the arc-shaped limiting plate 41 away from the arc-shaped clamping plate 42 is welded and fixed with a guide plate 43 extending to the outside of the placement groove 112, and the arc-shaped limiting plate 41, the arc-shaped clamping plate 42 and the guide plate 43 are all made of steel, and a first annular guide groove 132 and a second annular guide groove 133 are provided on the fixed plate 13 for the two opposite guide plates 43 to be inserted and rotated.

[0052] Reference Figure 3The arc-shaped limiting plate 41 is provided with a first magnetic member 411, which is a first magnet block embedded in the arc-shaped limiting plate 41. The inner walls of the first annular guide groove 132 and the second annular guide groove 133 are provided with a second magnetic member 1322, which abuts against and attracts the first magnetic member 411. The second magnetic member 1322 is an annular magnet block embedded in the inner walls of the first annular guide groove 132 and the second annular guide groove 133. This arrangement reduces the possibility of the arc-shaped limiting plate 41 rotating around the hinge axis in a natural state. The sides of the two arc-shaped limiting plates 41 that are close to each other are provided with an arc-shaped protrusion 412, which has the contour shape of one-third of a sphere. When the arc-shaped limiting plate 41 is used to clamp the metal pen tip inside the limiting hole 111, the arrangement of the arc-shaped protrusion 412 further reduces the possibility of the metal pen tip escaping from the lower opening of the limiting hole 111.

[0053] Reference Figure 6 and Figure 7 The first annular guide groove 132 and the second annular guide groove 133 are both provided with an abutment portion 1321 on the bottom side of the inner wall below the drill bit 22. The upper side of the abutment portion 1321 is flush with the upper side of the fixed plate 13. Therefore, when the guide plate 43 slides to abut against the upper side of the abutment portion 1321, the arc-shaped limiting plate 41 rotates around the hinge axis (see FIG. Figure 3 ) rotates in the direction away from the fixed disk 13, and clamps the arc-shaped clamping plate 42 to the outer peripheral surface of the metal pen tip.

[0054] Reference Figure 7 and Figure 8 , an elastic pad 421 is fixed to the arc-shaped clamping plate 42 by glue; when the arc-shaped clamping plate 42 is not tightly pressed against the abutment portion 1321, the arc-shaped limiting plate 41 is affected by its own gravity, and the arc-shaped limiting plate 41 cooperates with the arc-shaped protrusion 412 (see Figure 3 ) The metal pen tip is simply clamped to prevent the metal pen tip from falling off from the bottom of the limiting hole 111; when the limiting hole 111 with the metal pen tip is rotated to the bottom of the drill bit 22, due to the setting of the abutment portion 1321, the arc-shaped clamping plate 42 is clamped to the outer peripheral surface of the metal pen tip, reducing the possibility of the metal pen tip loosening or offsetting inside the limiting hole 111 when the drill bit 22 is drilling.

[0055] Reference Figure 6 The fixing plate 13 is provided with a plurality of limiting holes 111 (see FIG. Figure 7 ) The detection hole 134 and the discharge hole 135 overlap, and the detection hole 134 is located between the abutment portion 1321 and the discharge hole 135.

[0056] Reference Figure 9 and Figure 10, a detection component 5 is provided on the processing table 1, and the detection component 5 includes a sensor 51 located above the detection hole 134 and a second air pipe 52. A driving source 53 for providing compressed air to the second air pipe 52 is also provided on the side of the processing table 1.

A support frame 15 is provided on the side of the processing table 1, and the driving source 53 is a second air pump 531 fixed on the side of the processing table 1; the sensor 51 is fixed on the support frame 15, and the sensor 51 is used to monitor whether the metal pen tip after drilling meets the standard, and transmit the detection information to the processor. The processor determines the next processing step according to the drilling effect; when the drilling of the metal pen tip meets the standard, the rotating disk 11 continues to rotate, and the metal pen tip that has passed the inspection is rotated to the discharge hole 135 (see Figure 6 When it does not meet the standards, start the second air pump 531, and open the second control valve 521, through the impact of compressed gas to overcome the arc-shaped projection 412 (see Figure 3 ) is limited, and the metal pen tip located inside the limit hole 111 is discharged from the lower opening of the detection hole 134; the interior of the processing table 1 is provided with a waste collection frame 6 located below the detection hole 134, which is used to collect waste materials detected as unqualified drilling.

[0057] Reference Figure 11 The processing table 1 is provided with a third air pipe 7 located above the discharge hole 135. The driving source 53 simultaneously supplies compressed gas to the third air pipe 7. The third air pipe 7 is provided with a third control valve 71 for controlling its own on-off. The third control valve 71 is a solenoid valve. When the metal pen tip that has been tested and qualified rotates to a position that coincides with the discharge hole 135, the second air pump 531 is started and the third control valve 71 is opened. The arc-shaped protrusion 412 (see FIG. 4 ) is overcome by the impact of the compressed gas. Figure 3 ) The metal pen tip is limited so that the metal pen tip that has passed the inspection can be separated from the lower opening of the discharge hole 135; the interior of the processing table 1 is provided with a finished product collection frame 8 located below the discharge hole 135, and the finished product collection frame 8 is used to collect the metal pen tips that have been processed and passed the inspection.

[0058] The implementation principle of the embodiment of this application is:

[0059] When drilling a metal pen tip, the metal pen tip is first moved through the feed hole 131 on the fixed disk 13 to the inside of the limiting hole 111 by the setting of the feed assembly 3. The limiting setting of the arc-shaped limiting plate 41 and the arc-shaped protrusion 412 reduces the possibility of the metal pen tip inside the feed hole 131 escaping from the lower opening of the limiting hole 111. Then, the driving motor 121 drives the rotating disk 11 to rotate, so that the limiting hole 111 with the metal pen tip is rotated to the bottom of the drill bit 22.

[0060] When the limiting hole 111 with the metal pen tip is rotated to the bottom of the drill bit 22, due to the arrangement of the abutment portion 1321, the arc-shaped limiting plate 41 rotates around the hinge axis in a direction away from the fixed plate 13, and the arc-shaped clamping plate 42 is clamped to the outer peripheral surface of the metal pen tip, so that the arc-shaped clamping plate 42 is clamped to the outer peripheral surface of the metal pen tip, which facilitates the drilling process of the metal pen tip by the drill bit 22;

[0061] The metal pen tip after drilling continues to rotate with the rotating disk 11 to the bottom of the sensor 51. When the sensor 51 detects that the processing of the metal pen tip does not meet the standards, the second air pump 531 is started, and the second control valve 521 is opened, and the second air pipe 52 is used to discharge the metal pen tip inside the limit hole 111 from the lower opening of the detection hole 134; when the sensor 51 detects that the drilling of the metal pen tip meets the standards, the rotating disk 11 continues to rotate, and the metal pen tip that has passed the inspection is rotated to the bottom of the discharge hole 135, and the metal pen tip that has passed the inspection is detached from the lower opening of the discharge hole 135 through the third air pipe 7.
