Description

Technical Field

[0001] This utility model belongs to the field of plucked string instrument processing technology, and relates to a grooving mechanism for the sound hole of a plucked string instrument panel. Background Technology

[0002] Plucked string instruments are a type of stringed instrument. Different effects can be achieved through different operations by the user. The vibration of the strings allows the user to perform or express emotions. Performers primarily play by plucking strings. The sound holes on the soundboard of plucked string instruments require a grooving mechanism to create the holes. Existing technology, such as the grooving mechanism disclosed in patent publication number CN220330029U, has the following key technical points: It includes a support frame, with a protective shell fixedly mounted on its top surface. The protective shell has mounting holes on its top surface, and a first electric push rod is fixedly mounted inside the mounting holes. Second electric push rods are fixedly mounted on both sides of the inner wall of the protective shell. An adjustment component is located inside the protective shell and is used to change its position during grooving. By setting up the adjustment component, the grooving can be done in a polygonal pattern without manual adjustment, thus creating more precise grooves, saving manpower and improving work efficiency. A moving block is included; by sliding the moving block inside the mounting groove, the position can be adjusted forward and backward. Connecting to the first electric push rod, it can be adjusted up and down, ensuring that the position is not restricted during grooving.

[0003] The aforementioned grooving mechanism has the disadvantage of not being able to feed continuously and not being able to unload quickly after grooving when processing instrument soundboards. It requires manual intervention during the feeding and unloading process, which greatly reduces efficiency. To address this, we have designed a grooving mechanism for the sound holes of plucked string instruments. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a CNC indexing head that is simple in structure, has precision marking, and is extremely accurate.

[0005] The objective of this utility model can be achieved through the following technical solution: a grooving mechanism for the sound holes of a plucked string instrument panel, comprising a base, a processing table, a panel processing cover, a control panel, and a servo motor. The processing table is welded to the top of the base, and the top of the processing table is bolted to the panel processing cover. The side of the panel processing cover is connected to the servo motor via a bracket. A belt drive box is installed at the output end of the servo motor. A bearing coupling is installed at the output shaft of the belt drive box. A rotating cutter shaft is installed at the bottom end of the bearing coupling. A grooving cutter head is installed at the bottom end of the rotating cutter shaft. The system also includes a feeding assembly and a discharging assembly. The feeding assembly includes a first side plate, a second side plate, an adjusting crossbeam, and an upper... The assembly includes a feeding track and a top feeding track. The feeding track is installed at the top of the processing table and is driven by a cylinder. The top feeding track is installed at the top of the feeding track. An adjusting beam is installed on the front of the panel processing cover, and the first and second side material plates slide on the adjusting beam. The unloading assembly includes a limiting cylinder installed at the top of the processing table. A panel limiting edge strip is installed at one end of the limiting cylinder. A lifting limiting edge strip is movably installed on the side of the panel limiting edge strip. The lifting limiting edge strip is connected to the inner side of the processing table by a cylinder. A dropping slope is provided on the side of the top of the processing table. A collection frame connected to the side of the processing table is installed at the bottom of the dropping slope.

[0006] In the aforementioned grooving mechanism for the sound holes of a plucked string instrument, a hollow bracket is installed at the fixed end of the bearing seat. The bottom end of the hollow bracket is connected to the rotating cutter shaft via a sealed bearing. An industrial water pump is installed on the side of the hollow bracket, and a flushing head is installed at the outlet of the industrial water pump. This arrangement allows the grooving cutter head to be flushed with the flushing head, removing residual wood chips and ensuring good grooving accuracy during the grooving process, while also reducing wear on the grooving cutter head.

[0007] In the aforementioned grooving mechanism for the sound holes of a plucked string instrument panel, a feed inlet is provided at the bottom of the panel processing cover, corresponding to the loading and unloading components. This arrangement facilitates the loading track and top rail to push the panel into the inner side of the panel processing cover, thereby moving the panel between the panel limiting edge strip and the lifting limiting edge strip, thus achieving panel positioning.

[0008] Specifically, the opening height of the feed inlet is greater than the sum of the heights of the feeding track and the top track. This design is for better panel loading and to ensure that the feeding track is not interfered with by the structure of the panel processing cover during its movement.

[0009] In the aforementioned grooving mechanism for the soundholes of a plucked string instrument panel, balance rods are provided at both ends of the feeding track. Balance tracks are slidably mounted on the bottom ends of both balance rods. Both balance tracks are located at the top of the processing table and extend to the inner side of the panel processing cover. This design aims to ensure good stability, making the feeding track stable during movement and reducing fluctuations during cylinder drive.

[0010] In the aforementioned grooving mechanism for the sound holes of a plucked string instrument panel, an electrical box is installed at the corner of the top of the processing table, contacting the side of the panel processing cover. The front of the electrical box is connected to the control panel circuit. This arrangement facilitates centralized control of electrical equipment such as the servo motor and the cylinders connected to the feeding track via the control panel, ensuring good control performance and electrical operation.

[0011] Compared with the prior art, the advantages of the grooving mechanism for the sound hole of the plucked string instrument panel of this utility model are as follows: by setting up a feeding component including a first side plate, a second side plate, an adjusting crossbeam, a feeding track and a top material strip, and setting up a discharging component including a limiting cylinder, a panel limiting edge strip, a lifting limiting edge strip and a discharging inclined plate, it has a good feeding and discharging effect, and does not require too much manual intervention in the feeding and discharging process, thus ensuring production efficiency.

[0012] A hollow bracket is installed at the fixed end of the bearing coupling. The bottom end of the hollow bracket is connected to the rotating cutter shaft through a sealed bearing. An industrial water pump is installed on the side of the hollow bracket. A flushing head is installed at the outlet of the industrial water pump. The grooving cutter head can be flushed through the flushing head to remove residual wood chips on the grooving cutter head, ensuring good grooving accuracy during the grooving process, and also reducing the wear of the grooving cutter head.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to a grooving mechanism for the sound holes on the soundboard of a plucked string instrument.

[0019] The grooving mechanism includes a base 1, a processing table 2, a panel processing cover 3, a control panel 13, and a servo motor 14. The processing table 2 is welded to the top of the base 1, and the top of the processing table 2 is bolted to the panel processing cover 3. An electrical box 12 is installed at the corner of the top of the processing table 2, which contacts the side of the panel processing cover 3. The front of the electrical box 12 is electrically connected to the control panel 13. The side of the panel processing cover 3 is connected to the servo motor 14 through a bracket. A belt drive box 15 is installed at the output end of the servo motor 14. A bearing coupling 16 is installed at the output shaft of the belt drive box 15. A rotary cutter shaft 17 is installed at the bottom of the bearing coupling 16. A grooving cutter head 18 is installed at the bottom of the rotary cutter shaft 17. A feed port 11 is provided at the bottom of the panel processing cover 3. The opening height of the feed port 11 should be large enough to ensure the effective movement of the panel and the feeding track 7 of the feeding assembly.

[0020] The belt drive box 15 includes two pulleys, a belt, and a long box. The two pulleys are mounted on the box via a shaft, and the belt is connected between the two pulleys to form a belt transmission. The two pulleys are connected to the servo motor 14 and the bearing coupling 16 via key shafts, respectively. This transmission component is existing known technology and will not be described again.

[0021] Example 1: It also includes a feeding assembly and a discharging assembly; wherein: the feeding assembly includes a first side plate 4, a second side plate 5, an adjusting beam 6, a feeding track 7 and a top material bar 8. The feeding track 7 is installed on the top of the processing table 2 and is driven to move by a cylinder. The top material bar 8 is installed on the top of the feeding track 7. The adjusting beam 6 is installed on the front of the panel processing cover 3 and the first side plate 4 and the second side plate 5 slide on the adjusting beam 6.

[0022] The unloading assembly includes a limiting cylinder 22 installed on the top of the processing table 2. A panel limiting strip 23 is installed at one end of the limiting cylinder 22. A lifting limiting strip 24 is movably installed on the side of the panel limiting strip 23. The lifting limiting strip 24 is connected to the inside of the processing table 2 via a cylinder. A dropping slope 25 is installed on the side of the top of the processing table 2. A collection frame 26 is installed and connected to the bottom of the dropping slope 25 on the side of the processing table 2.

[0023] In use: The distance between the first side plate 4 and the second side plate 5 can be adjusted to place a panel of a suitable size. The panel is placed between the first side plate 4 and the second side plate 5 in a stacked manner. During feeding, the feeding track 7 is driven by the cylinder, which drives the top material bar 8 to push the bottom panel into the space between the panel limiting edge bar 23 and the lifting limiting edge bar 24. The lifting limiting edge bar 24 is in the raised state and works with the panel limiting edge bar 23 to limit and fix the panel, which can ensure good stability during the grooving process. After grooving, the lifting limiting edge bar 24 falls and is flush with the table surface of the processing table 2, which can prevent the panel from falling. The limiting cylinder 22 is further driven to push the panel onto the dropping slope 25. Under the action of gravity, the panel slides down the dropping slope 25 into the collection frame 26.

[0024] Furthermore, balance rods 9 are installed at both ends of the feeding track 7, and balance tracks 10 are slidably installed at the bottom ends of both balance rods 9. Both balance tracks 10 are located at the top of the processing table 2 and extend to the inside of the panel processing cover 3. This ensures that the movement of the feeding track 7 has good stability and movement accuracy.

[0025] Example 2: The grooving mechanism includes a base 1, a processing table 2, a panel processing cover 3, a control panel 13, and a servo motor 14. The processing table 2 is welded to the top of the base 1, and the top of the processing table 2 is bolted to the panel processing cover 3. The side of the panel processing cover 3 is connected to the servo motor 14 through a bracket. A belt drive box 15 is installed at the output end of the servo motor 14. A bearing coupling 16 is installed at the output shaft of the belt drive box 15. A rotary cutter shaft 17 is installed at the bottom end of the bearing coupling 16. A grooving cutter head 18 is installed at the bottom end of the rotary cutter shaft 17. A feed inlet 11 is provided at the bottom of the panel processing cover 3. A hollow bracket 19 is installed at the fixed end of the bearing coupling 16. The bottom end of the hollow bracket 19 is connected to the rotary cutter shaft 17 through a sealed bearing. An industrial water pump 20 is provided on the side of the hollow bracket 19. A flushing head 21 is installed at the outlet of the industrial water pump 20.

[0026] The solution is designed to rinse the grooving head 18 with the rinsing head 21, which can remove residual wood chips from the grooving head 18, ensure good grooving accuracy during the grooving process, and reduce the wear of the grooving head 18.
