[0020] In one embodiment, such as Figure 1 and Figure 2As shown, a gantry-type reed finishing machine includes a base plate 100, a jig frame structure 200, a gantry frame 300, and a tool holder structure 400. The base plate 100 has transverse components 700 at both ends along its width direction, and longitudinal components 800 on both sides along its length direction. The jig frame structure 200 is mounted on one of the longitudinal components 800, and a template adjustment frame 600 is mounted on the other longitudinal component 800. The jig frame structure 200 includes a jig frame 210, a jig knob 220, and a jig clamping unit 230. The jig frame 210 is mounted on the longitudinal component 800 and has a 240. One end of the jig frame 210 protrudes upward and has a hole adapted to the jig 500. A knob 220 is located at the hole, and the fixture 500 is inserted into the hole and connected to the fixture knob 220; the fixture clamping unit 230 is located at the end of the fixture frame 210 away from the fixture knob 220, and the fixture clamping unit 230 is used to clamp the whistle; the gantry frame 300 is located between the template adjustment frame 600 and the fixture frame structure 200, and both ends of the gantry frame 300 are connected to two transverse components 700, which are used to adjust the transverse position of the gantry frame 300 on the base plate 100; the tool holder structure 400 is located on the upper side of the gantry frame 300, and its middle part is rotatably connected to the upper surface of the gantry frame 300. One end of the tool holder structure 400 is equipped with a 450 for finishing the fixture 500, and the other end can be separated and abutted against the upper surface of the template adjustment frame 600.

[0021] In this embodiment of the invention, the whistle is placed on the fixture 500 and fixed by the fixture clamping unit 230. The tool holder structure 400 is twisted so that the tool holder structure 400 is at a 90-degree angle to the gantry 300, with one end 450 of the tool holder structure 400 in close contact with the whistle. The height of the tool holder structure 400 on the gantry 300 is adjusted to adjust the thickness of the whistle. The fixture knob 220 is rotated, which drives the fixture 500 to rotate, thus adjusting the direction of the whistle processing. During processing, the operator manually pushes the longitudinal component 800 to adjust the fixture holder structure 200 and... The template adjustment frame 600 moves back and forth along the length of the base plate 100, thus causing the jig 500 and the reed to move back and forth longitudinally to achieve longitudinal processing of the reed. At the same time, the operator can also use their hands to act on the transverse component 700, causing the gantry 300 and the tool holder structure 400 to move back and forth laterally. The 450 on the tool holder structure 400 moves laterally to achieve transverse processing of the reed. Therefore, the reed can be processed in multiple directions, has a fine processing function, and is suitable for processing reeds with different performance needs. During processing, there is no need to disassemble the reed, which improves processing efficiency.

[0022] In one embodiment, such as Figure 1 and Figure 2As shown, the clamping unit 230 includes a clamping shaft 231, a tightening screw 233, and two clamping blocks 232. The two clamping blocks 232 are rotatably connected to the end of the clamping frame 210 via the clamping shaft 231. The two clamping blocks 232 are arranged opposite to each other and connected by a spring. The tightening screw 233 passes through the two clamping blocks 232 and is screwed into them. In this embodiment of the invention, the end of the tightening screw 233 is screwed to make the clamping block rotate. The rotating tightening screw 233 can rotate synchronously in opposite directions through its cooperation with the two clamping blocks 232 and the connection of the spring, so as to tighten or loosen the tail of the whistle.

[0023] In one embodiment, such as Figure 1 and Figure 2 As shown, the tool holder structure 400 includes a tool holder 410 and a limiting contact head 420. The middle position of the tool holder 410 is rotatably connected to the gantry frame 300 via a tool holder pivot 430. One end of the tool holder 410 has a 450, within which a corresponding tool of the fixture 500 can be installed. The limiting contact head 420 is disposed at the end of the tool holder 410 pointing towards the template adjustment frame 600 via a height adjustment bolt 440, and the limiting contact head 420 corresponds to the template adjustment frame 600. In the novel embodiment, in the non-working state, the tool holder 410 and the gantry 300 are aligned vertically. In the working state, the tool holder 410 is twisted so that the tool holder 410 and the gantry 300 are stacked vertically in a cross shape, with the tool abutting against the upper surface of the fixture 500. The height of the limiting contact head 420 is adjusted by the height adjusting bolt 440 so that the bottom of the limiting contact head 420 abuts against the upper surface of the template adjusting frame 600. The height adjustment of the tool during fine finishing is guided by the mold to ensure the fine finishing effect.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the upper surface of the template adjustment frame 600 has a crescent plate 610 and a mold part 620. The two ends of the mold part 620 are detachably fixed to the template adjustment frame 600 by screws. The crescent plate 610 is located on the upper surface of the mold part 620 and is fixed by screws. The crescent plate 610 is in contact with the bottom end of the limiting contact head 420. When the processing arc of the whistle is adjusted, the screws of the mold part 620 are removed. By adding shims to the gaps on both sides between the mold part 620 and the template adjustment frame 600, the balance of the tool holder 410 is changed, thereby adjusting the processing arc of the whistle. The processing length of the whistle is adjusted by adjusting the position of the tool holder 410 on the limiting contact head 420.

[0025] In one embodiment, such as Figure 1 and Figure 2As shown, the transverse assembly 700 includes a transverse frame 710 and a transverse slide rail 720. The transverse frame 710 is fixed to the end of the base plate 100 and is arranged transversely. The transverse slide rail 720 is fixed to the upper surface of the transverse frame 710. The transverse slide rail 720 has a transverse slide block 730 that can slide along its length. One end of the gantry frame 300 is fixedly connected to the transverse slide block 730. The transverse frame 710 is also provided with a boss and a transverse adjustment knob 740 is provided on the boss. One end of the transverse adjustment knob 740 abuts against the side wall of the gantry frame 300. In this embodiment of the present invention, rotating the transverse adjustment knob 740 allows the gantry frame 300 and its two transverse slide blocks 730 to move back and forth along the transverse slide rail 720 by cooperating with the boss.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, one of the transverse frames 710 is provided with a stroke screw hole 750, which is divided into a fixed stroke screw hole and a partially formed screw hole; the longitudinal component 800 includes a longitudinal slide rail 810, a longitudinal slide block 820, and a longitudinal support 830. The longitudinal support 830 is fixed between the two transverse components 700, the longitudinal slide block 820 is slidably mounted on the longitudinal support 830, the longitudinal slide rail 810 is fixed on the longitudinal slide block 820, and the longitudinal slide rails 810 in the two longitudinal components 800 are connected together. One of the longitudinal slide rails 810 has a longitudinal cylinder 840. This utility model embodiment In the example, under normal conditions, a stroke screw is screwed into the fixed stroke screw hole. The stroke screw rests against the longitudinal slide rail 810. The operator pushes the longitudinal cylinder 840 by hand, and the two sets of longitudinal slide blocks 820 and longitudinal support 830 slide back and forth along the longitudinal slide rail 810, thereby realizing the movement of the jig frame structure 200 and the template adjustment frame 600. Therefore, the jig 500 and the whistle move longitudinally relative to the tool to realize the overall fine finishing of the whistle. When the whistle is partially finely finished: the stroke screw is removed, and then a local adjustment screw is added at the position of the local adjustment screw hole to realize the adjustment of the processing stroke, and finally realize that the front part of the whistle can be processed separately.

[0027] The above embodiment provides a gantry-type reed repair machine, the working principle of which is as follows:

[0028] This precision finishing machine achieves fine processing of the reed through the coordinated operation of multiple components. The specific process is as follows:

[0029] First, prepare for processing by placing the reed on the fixture 500 and fixing it by the fixture clamping unit 230. Tighten the tightening screw 233 so that it can rotate synchronously and oppositely with the two clamping blocks 232 through the cooperation with the spring, thereby clamping and fixing the tail of the reed.

[0030] Next, processing and adjustments are performed. The tool holder structure 400 is twisted so that it is stacked vertically at a 90-degree angle to the gantry 300, with the tool 450 at one end of the tool holder structure 400 in close contact with the whistle. The thickness of the whistle is adjusted by adjusting the height of the tool holder structure 400 on the gantry 300. The jig knob 220 is rotated, which drives the jig 500 to rotate, thus adjusting the direction of the whistle processing. At the same time, the height of the limit contact head 420 is adjusted by the height adjustment bolt 440 so that its bottom abuts against the surface of the crescent plate 610 on the template adjustment frame 600. The height of the tool 450 during fine finishing is guided by the mold to ensure the finishing effect. If the whistle processing curvature needs to be adjusted, the screws of the mold part 620 can be removed, and shims can be added to the gaps on both sides between the mold part 620 and the template adjustment frame 600 to change the balance of the tool holder 410. The processing length of the whistle can be adjusted by adjusting the position of the tool holder 410 on the limit contact head 420.

[0031] During processing, the operator manually pushes the longitudinal cylinder 840 of the longitudinal component 800, causing the two sets of longitudinal slides 820 and the longitudinal support 830 to slide back and forth along the longitudinal slide rail 810. This drives the fixture frame structure 200 and the template adjustment frame 600 to move back and forth along the length of the base plate 100, thereby causing the fixture 500 and the whistle to move longitudinally back and forth, achieving longitudinal processing of the whistle. At the same time, rotating the transverse adjustment knob 740, which, in cooperation with the boss, pushes the gantry 300 and its two transverse slides 730 to move back and forth along the transverse slide rail 720, driving the tool holder structure 400 to move laterally back and forth, causing the tool 450 to move laterally, achieving transverse processing of the whistle.

[0032] In addition, the processing stroke is adjustable: under normal conditions, a stroke screw is screwed into the fixed stroke screw hole of the transverse frame 710, which abuts against the longitudinal slide 810 to achieve overall fine finishing of the reed; when fine finishing a part of the reed, the stroke screw is removed and a local adjustment screw is added at the position of the local adjustment screw hole to achieve adjustment of the processing stroke, and the front part of the reed can be processed separately.
