Detailed Embodiment

[0030] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings. Embodiment

[0031] As Figures 1-3 collectively shown, the present utility model provides a cutter head quick-change device, including a cutter head 1, a first quick-change positioning clamp handle 4, and a rotary chuck 5. The rotary chuck 5 can be a pneumatic rotary chuck or a hydraulic rotary chuck. In this solution, a pneumatic rotary chuck is preferably used. The first quick-change positioning clamp handle 4 is installed on the cutter head 1 by bolts. The clamping mechanism of the rotary chuck 5 can quickly clamp and connect the first quick-change positioning clamp handle 4, enabling the quick connection and disassembly of the cutter head 1 and the rotary chuck 5. Using the first quick-change positioning clamp handle 4 to connect the rotary chuck 5 and the cutter head 1, when it is necessary to adapt to different specifications of cutter heads, due to the existence of the first quick-change positioning clamp handle 4, there is no need to replace the rotary chuck 5.

[0032] The rotary mechanism of the rotary chuck 5 drives the first quick-change positioning clamp handle 4 and the cutter head 1 to rotate together through the clamping mechanism.

[0033] Furthermore, the first quick-change positioning clamp handle 4 is a cylindrical structure with a T-shaped cross-section. The first quick-change positioning clamp handle 4 includes a cylindrical portion 41, a disc portion 42 is formed on the top of the cylindrical portion 41, and the disc portion 42 is fixedly connected to the cutter disc 1; the clamping mechanism of the rotary chuck 5 clamps the cylindrical portion 41.

[0034] The cutter disc 1 is circular, and a plurality of tool handle clamps 2 are arranged at intervals along the circumferential direction of the cutter disc 1, and the tool handle clamps 2 are used to fix the tool handle.

[0035] The cutter disc 1 is also provided with a handle 3 or a mechanical arm clamping interface or other structures to assist in the disassembly and translation of the cutter disc 1 , which is used for manual or mechanical hand to disassemble and translate the cutter disc 1 as a whole.

[0036] The bottom of the rotary chuck 5 is connected to the driving part through the connecting plate 7. The driving part includes a reducer 8 and a servo motor 11. The servo motor (11) is connected to the reducer (8). The connecting plate 7 mainly serves as an intermediate transmission function for connecting the rotary chuck 5 and the reducer 8.

[0037] The tool disc quick-change device further comprises a tool magazine support frame 10 , on which a connecting seat 9 is arranged, and the reducer 8 is mounted on the connecting seat 9 .

[0038] Furthermore, the tool magazine support frame 10 is in an oblique wedge shape, and includes an upper plate, the upper surface of which is a plane, and a side plate is respectively arranged on both sides of the upper plate, and the bottom of the side plate is an inclined surface.

[0039] The servo motor 11 and the reducer 8 are located between the two side plates. Preferably, the lower ends of the servo motor 11 and the reducer 8 are higher than the lowest end of the tool magazine support frame 10. This arrangement enhances the stability of the device and reduces the occupied space, especially avoiding the accidental collision of the servo motor or the reducer when the tool magazine support frame 10 descends to the lowest position of the travel during the lifting and lowering process of the tool magazine support frame 10. During use, the tool disc quick change device can be connected to the lifting mechanism through the tool magazine support frame 10, and the lifting mechanism drives the tool magazine support frame 10 to be lifted and lowered, thereby driving the tool disc quick change device to be lifted and lowered as a whole.

[0040] The tool magazine support frame 10 is provided with a weight reduction structure. Specifically, weight reduction holes 12 are provided on the flat plate and the side plates.

[0041] The reducer 8 is a reversing reducer, the output shaft of the reversing reducer is vertically arranged, and the input shaft is horizontally arranged; the output shaft of the servo motor 11 is horizontally arranged, and the input shaft of the reversing reducer is drivingly connected with the output shaft of the servo motor 11.

[0042] A stop bracket 6 is provided on the tool magazine support frame 10 , and the stop bracket 6 fixes the housing of the rotary chuck 5 .

[0043] A tool detection switch 13 is provided on the top of the stop bracket 6 through a bracket. The tool detection switch 13 is used to detect whether there is a tool. The tool detection switch 13 is arranged corresponding to the rotation path of the tool placed on the tool disc 1.

[0044] The tool disc 1 is arranged above the tool magazine support frame 10, and stable connection can be fully achieved by relying on gravity. When replacing, it can be easily disassembled and replaced, avoiding the problems of hoisting or supporting when the tool disc 1 is arranged below for replacement.

[0045] The tool disc 1 has upper and lower layers of disc bodies. Tool holders 2 are arranged on each layer of disc body. The tool holders 2 of the two layers of disc bodies are arranged staggeredly to prevent interference.

[0046] Furthermore, the diameters of the two layers of disc bodies are set to be one large and one small. More preferably, the diameter of the upper layer of disc body is smaller than that of the lower layer of disc body, further reducing interference.

[0047] The two layers of disc bodies are connected together through a support ring 14 and a second quick-change positioning handle 15. The support ring 14 is arranged on the upper part of the lower layer of disc body. A groove is opened in the center of the support ring 14. The second quick-change positioning handle 15 has the same structure as the first quick-change positioning handle 4. The second quick-change positioning handle 15 is arranged on the lower part of the upper layer of disc body. The cylindrical part 41 of the second quick-positioning handle 15 is butted against the groove in the center of the support ring 14. There is no need to clamp, which is convenient for quick replacement, and each disc body can be used alone or in combination.

[0048] The setting of the support ring 14 and the second quick-change positioning handle 15 enables the number of layers of the tool disc to be increased or decreased according to needs in actual production.

[0049] The working principle of the present utility model:

[0050] When the tool disc needs to be replaced, the rotary chuck 5 relaxes the first quick-change positioning handle 4, and the tool disc can be taken out. The quick-positioning handle of another tool disc is placed in the rotary chuck 5, and the rotary chuck 5 acts to clamp, realizing the replacement of the tool disc, thereby realizing the overall replacement of the tool.

[0051] The above is an example of the best implementation mode of the present utility model. The parts not described in detail are all common general knowledge of those of ordinary skill in the art. The protection scope of the present utility model is subject to the content of the claims. Any equivalent transformation based on the technical inspiration of the present utility model is also within the protection scope of the present utility model.
