Description

Technical Field

[0001] The present invention relates to the field of CNC processing equipment for sound pipes, and more particularly to a CNC processing equipment for sound pipes with multi-faceted turning. Background Art

[0002] Metal sound pipes are common components in the field of musical instruments. They produce the tones required for music through the vibration of the air inside the pipes, have high strength and durability, and can withstand high pressure and temperature, thus being widely used in musical instrument manufacturing. Metal sound pipes are of a tubular structure. During the production process, they are mostly drilled through CNC drilling equipment. Multiple pairs of fixed seats are installed on the processing table of the CNC drilling equipment, and corresponding inner support chucks are installed on the fixed seats. The two ends of the sound pipe are fixed by each pair of inner support chucks. A corresponding number of drilling mechanisms are installed on the gantry, and each drilling mechanism is used to drill holes in the rough material of the fixed sound pipe. In musical instrument manufacturing, metal sound pipes are mostly produced in shapes such as circular tubes or rectangular tubes to produce different tones and timbres. However, most of the existing CNC drilling equipment for sound pipes only has fixed seats for fixing single types of sound pipes, which limits the versatility and flexibility of the equipment. When drilling different-shaped sound pipes, it is necessary to manually disassemble and assemble to replace different fixed seats, which undoubtedly increases the operation time, reduces the processing efficiency, and does not meet the processing requirements for continuously processing different tubular metal sound pipes.

[0003] Therefore, we make improvements and propose a CNC processing equipment for sound pipes with multi-faceted turning. Summary of the Invention

Among them, at the end of the block on the speed reducer, there is a convex clamping portion. At the end of the block on the inner support chuck, there is a slot adapted to the convex clamping portion.

[0010] As a preferred technical solution of this application, the fixture frame is a hollow plate-like structure. At the outer end of the fixture frame, installation pipe seats for the self-rotating shaft to pass through are embedded equidistantly in a ring shape.

A second vertical plate is installed on the side of the plate frame, and the output end of the second driving cylinder is fixed to the bottom end of the second vertical plate.

[0012] As a preferred technical solution of the present application, a set of linkage rods are slidably arranged on the support frame located at the top. The linkage rods are coaxial with the corresponding support tubes and the outer ends are fixed to the slide frame. Connection seats are arranged at the first rotary tube seat and the second rotary tube seat on the linkage rods. A driving slider is elastically arranged on the side of the connection seat. Driving grooves adapted to the driving slider are formed on the inner walls of the first rotary tube seat and the second rotary tube seat.

When the driving slider continues to move, it presses the arc groove, and the fixture frame starts to drive the inner support chuck to rotate synchronously. When the driving slider is located at the outer end of the arc groove, the switching operation of the inner support chuck is completed. At this time, the driving slider is also located at the end of the adjacent linear groove, which is convenient for the linear reset of the driving slider. Further, when the driving slider is located in the driving groove, it also limits the self-rotation of the fixture frame to avoid deviation of the inner support chuck; 3.

Detailed implementation manners

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As described in the background art, most of the existing sound tube CNC drilling equipment only has a fixed seat for fixing a single type of sound tube, which limits the versatility and flexibility of the equipment. When drilling and processing sound tubes of different shapes, it is necessary to manually disassemble and assemble to replace different fixed seats, which undoubtedly increases the operation time, reduces the processing efficiency, and does not meet the processing requirements for continuously different tubular metal sound tubes.

[0021] To solve this technical problem, please refer to Figures 1 to 4, the present invention provides a multi-faceted turning CNC processing equipment for sound pipes, including a machine tool 100. On the machine tool 100, there is a drilling module 101 that moves along the X-Z axis direction and a sliding table module 102 that moves along the Y axis. Both the drilling module 101 and the sliding table module 102 are existing mature technical means, and their specific structures and working principles will not be elaborated here; It further includes a support frame 200 installed on the sliding table module 102. In the middle of the support frame 200, there is a group of support pipes 201. At both ends of the support pipe 201, a first rotating pipe seat 300 and a second rotating pipe seat 301 are coaxially installed respectively. On both the first rotating pipe seat 300 and the second rotating pipe seat 301, there is a fixture frame 302. On the fixture frame 302, a group of rotatable inner support chucks 303 are arranged at equal intervals in a ring shape. Preferably, the inner support chuck 303 includes a frustum-shaped chuck and other prism-shaped chucks adapted to the inner wall of the sound pipe, and specifically, it can be installed on the fixture frame 302 according to the range requirements of the actual production of sound pipes; Through the provided fixture frame 302, a plurality of inner support chucks 303 with different shapes are fixedly installed on the fixture frame 302. When opening holes in sound pipes of different shapes, the first rotating pipe seat 300 and the second rotating pipe seat 301 can be rotated so that the required inner support chuck 303 is located above the support frame 200, meeting the fixing requirements of sound pipes of corresponding shapes. The operation is simple and fast, avoiding the cumbersome process of disassembling and assembling related parts required for traditional chuck replacement, and improving the flexibility and practicality of the equipment; Among them, the fixture frame 302 at one end of the support pipe 201 is fixed to the first rotating pipe seat 300 through fasteners. Preferably, on the side of the first rotating pipe seat 300, there is a mounting plate adapted to the fixture frame 302. Holes can be opened on the fixture frame 302 and the mounting plate, and the fixture frame 302 and the first rotating pipe seat 300 can be fixedly installed through conventional fasteners such as bolts and nuts. At one end of the support frame 200, a sliding frame 400 is slidably arranged. On the sliding frame 400, a driving module for driving each inner support chuck 303 to rotate is installed. At the output end of the driving module and the end of each inner support chuck 303, there are respectively adapted blocks 406; through the provided sliding frame 400, the sliding frame 400 can be driven to move away from the chuck, so that the driving module is separated from the end of the inner support chuck 303, and then the fixture frame 302 can be rotated to implement the operation of switching the inner support chuck 303. Correspondingly, when the two blocks 406 are adaptively clamped, the inner support chuck 303 connected thereto can be driven to rotate by the driving module, so that the sound pipe clamped and fixed between the two inner support chucks 303 can rotate synchronously, realizing the switching of the opening surface of the sound pipe; Specifically, the fixture frame 302 located at the other end of the support tube 201 is slidably sleeved on the second rotary tube base 301. A connecting tube 304 coaxial with the support tube 201 is fixed in the middle of the fixture frame 302. A plate frame 500 is slidably arranged at the other end of the support frame 200. The end of the connecting tube 304 is installed on the plate frame 500 through a bearing. The outer wall of the second rotary tube base 301 has annular and equally spaced convex ribs 3011. A chute 3041 adapted to the convex ribs 3011 is provided on the inner wall of the connecting tube 304. Through the arrangement of the convex ribs 3011 and the chute 3041, the plate frame 500 can drive the fixture frame 302 and the inner support chuck 303 to move linearly synchronously, so that a space for placing and fixing the sound tube is left between two corresponding inner support chucks 303. At the same time, the rotation of the second rotary tube base 301 can drive the connecting tube 304 to rotate self by the convex ribs 3011, thereby realizing the self-rotation of the fixture frame 302 here.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings.

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0025] Example 1, please refer to Figure 2 、 Figure 4 and Figure 5 , a multi-faceted turning sound tube CNC machining equipment, wherein the support frame 200 includes a pair of parallel support frames 2001. The middle of the support frame 2001 has a support rod 2002. The support tube 201 is fixedly embedded on the upper support rod 2002, and the support tube 201 penetrates through the support rod 2002. Through the provided support frame 2001, and the support tube 201 is located in the middle of the support frame 2001, a space for self-rotation is left for the fixture frame 302 and the inner support chuck 303 arranged on the fixture frame 302. The support frame 2001 at the bottom is installed on the slide module 102 and moves linearly along the table surface of the machine tool 100 through the slide module 102.

[0026] Further, as Figure 2 and Figure 7As shown in the figure, a first driving cylinder 401 is installed at the outer end of the support frame 2001 at the bottom. A first vertical plate 402 is fixed on the carriage 400. The output end of the first driving cylinder 401 is fixed to the bottom end of the first vertical plate 402. A set of slide rails 204 are installed at both ends of the support frame 2001. A slide seat 403 adapted to the slide rails 204 is installed at the bottom of the carriage 400. By driving the first driving cylinder 401 installed, the carriage 400 and the driving module located on the carriage 400 are moved away from the inner support chuck 303, which is convenient for quickly rotating the fixture rack 302 to switch the corresponding inner support chuck 303, saving labor.

[0027] Further, as Figures 2 to 4 shown in the figure, the driving module includes a driving motor 404 installed on the carriage 400 and a set of speed reducers 405 connected to the driving motor 404. The end of the inner support chuck 303 has a self-rotating shaft 305 passing through the fixture rack 302. Two clamping blocks 406 are respectively installed at the output end of the speed reducer 405 and the end of the self-rotating shaft 305. Among them, the end of the clamping block 406 located on the speed reducer 405 has a convex clamping portion 408, and the end of the clamping block 406 located on the inner support chuck 303 has a clamping groove 407 adapted to the convex clamping portion 408. By driving all the speed reducers 405 to run synchronously by the driving motor 404, the output end of the speed reducer 405 rotates, and then the corresponding inner support chuck 303 can be driven to rotate through the clamping relationship between the convex clamping portion 408 and the clamping groove 407. Correspondingly, the sound pipe located between the two inner support chucks 303 driven by the inner support chuck 303 rotates synchronously, so as to facilitate drilling holes on different surfaces of the sound pipe. At the same time, the speed reducer 405 can be driven by the carriage 400 to be separated from the corresponding inner support chuck 303, and the operation of rotating the fixture rack 302 to switch different inner support chucks 303 can be implemented. It should be noted that when all the inner support chucks 303 on the fixture rack 302 are located at the position opposite to the speed reducer 405, the clamping groove 407 is opposite to the convex clamping portion 408.

[0028] Further, as Figure 7 and Figure 8 shown in the figure, the fixture rack 302 is a hollow plate-like structure, that is, it has a circular mounting hole in the middle, which is convenient for mounting corresponding components. The outer end of the fixture rack 302 is annularly and equidistantly embedded with mounting pipe seats 3021 for the self-rotating shaft 305 to pass through, which is convenient for disassembly, installation and replacement of the inner support chuck 303.

[0029] Further, as Figure 4 and Figure 8As shown in the figure, a second driving cylinder 501 is installed at the inner end of the support frame 2001 at the bottom. The bottom end of the plate frame 500 has a sliding sleeve 502 adapted to the slide rail 204. A second vertical plate 503 is installed on the side of the plate frame 500. The output end of the second driving cylinder 501 is fixed to the bottom end of the second vertical plate 503. The operation of driving the plate frame 500 to perform linear motion is implemented through the second driving cylinder 501, which is convenient for quickly installing and replacing different sound pipes during the drilling process, improving the processing efficiency of opening holes in the sound pipes. Among them, both the second driving cylinder 501 and the first driving cylinder 401 are connected to the control system of the device. Correspondingly, there is also a switch (not shown in the figure) for controlling the corresponding mode.

[0030] In the specific implementation process, that is, when opening holes in the sound pipe blanks of the same shape, the second driving cylinder 501 works to drive the plate frame 500 to move away from the support pipe 201. The plate frame 500 drives the inner support chucks 303 on the fixture frame 302 to move synchronously, so that there is a space for installing the sound pipe between the two opposite inner support chucks 303. At this time, one end of the sound pipe can be sleeved on the inner support chuck 303 located at the first rotating pipe seat 300. By controlling the second driving cylinder 501 to reset, the inner support chuck 303 on the plate frame 500 enters the end of the sound pipe and cooperates with the other inner support chuck 303 to complete the fixation of the sound pipe. During the drilling stage, the drilling module 101 and the slide table module 102 can be driven according to specific production requirements. Among them, during the drilling process, through the operation of the driving motor 404 and each reducer 405, the sound pipe installed on the two inner support chucks 303 can be rotated to complete the opening hole requirements for different surfaces of the sound pipe.

[0031] Embodiment 2 further optimizes the multi-faceted turning sound pipe CNC processing equipment provided in Embodiment 1. Specifically, as Figure 2 、 Figure 4 、 Figures 7 to 10As shown in the figure, a set of linkage rods 600 are slidably arranged on the top support frame 2001. The linkage rods 600 are coaxial with the corresponding support pipes 201, and the outer ends are fixed to the carriage 400. Connecting seats 601 are arranged at the first rotary pipe seat 300 and the second rotary pipe seat 301 on the linkage rods 600. Driving sliders 602 are elastically arranged on the sides of the connecting seats 601. Driving grooves adapted to the driving sliders 602 are formed on the inner walls of the first rotary pipe seat 300 and the second rotary pipe seat 301. The driving grooves include a set of linear grooves 603 and arc grooves 604 that are annularly equidistant and alternately connected in sequence. The groove depth of one end of the linear groove 603 close to the carriage 400 is less than that of the other end. One end of the arc groove 604 is smoothly connected to the outer end of the linear groove 603, and the other end is smoothly connected to the inner end with a deeper groove depth of the adjacent linear groove 603. Among them, the number of the linear grooves 603 and the arc grooves 604 corresponds to the number of the inner support chucks 303 on the fixture frame 302. In this embodiment, three inner support chucks 303 are arranged on a single fixture frame 302. Correspondingly, the number of both the linear grooves 603 and the arc grooves 604 is three; During specific implementation, through the operation of the first driving cylinder 401, the carriage 400 is driven to move a certain distance outward. The moving distance is the groove length of the linear groove 603. During this process, the linkage rod 600 drives the driving slider 602 to move between the inner end of the linear groove 603 and the end of the arc groove 604 first. When moving to the arc groove 604, the clamping blocks 406 on each speed reducer 405 are separated from the clamping blocks 406 at the ends of the inner support chucks 303. Then, the carriage 400 continues to drive the linkage rod 600 and the driving slider 602 on the linkage rod 600 to continue moving. Since the groove depth of one end of the linear groove 603 close to the carriage 400 is less than that of the other end, and the driving slider 602 moves linearly, the driving slider 602 starts to squeeze the arc groove 604 during this moving process. As a result, the two driving sliders 602 drive the first rotary pipe seat 300 and the second rotary pipe seat 301 to rotate synchronously respectively, and the corresponding two fixture frames 302 rotate synchronously to complete the switching of the inner support chucks 303. Subsequently, the first driving cylinder 401 can be reset to drive the carriage 400 back to the initial position. The driving slider 602 slides along the corresponding linear groove 603 and is located at the inner end of the linear groove 603. The clamping blocks 406 on the speed reducer 405 are clamped with the clamping blocks 406 at the ends of the inner support chucks 303, that is, the switching work of the inner support chucks 303 on the fixture frame 302 is completed once; By driving the carriage 400 to make a reciprocating motion through the first driving cylinder 401, operations such as the separation of the speed reducer 405 from the inner support chuck 303, the synchronous self-rotation of all the fixture frames 302 located on the support frame 200, and the re-clamping of the speed reducer 405 with the inner support chuck 303 are realized, achieving the process of quickly replacing the inner support chuck 303. The structure is simple and the operation is convenient.

[0032] Further, as shown in Figures 5 to 6 , both ends of the support pipe 201 have step surfaces 2011 for installing the first rotary pipe seat 300 and the second rotary pipe seat 301. Activity slots 2012 for the driving sliders 602 to pass through are provided at the step surfaces 2011. In the initial stage, both driving sliders 602 are located at the inner ends of the activity slots 2012, that is, the driving sliders 602 are located at the inner ends of the linear slots 603.

[0033] Further, as shown in Figure 5 , activity holes 504 for the linkage rod 600 to penetrate are respectively provided on the plate frame 500 and the support frame, facilitating the installation and operation of the linkage rod 600. A sleeve 205 for the end of the linkage rod 600 to penetrate and slide is embedded at the end of the support frame 200. The length of the sleeve 205 is not less than the slot length of the linear slot 603, providing support for the end of the linkage rod 600 and improving the stability of the operation of the linkage rod 600.
