DETAILED DESCRIPTION

[0018] Referring to Figures 1 to 4 the drawings, a tool quick replacement device includes a tool body 7, further includes: a driving assembly, including a driving rotary support seat 2, a driving motor 4 and a driving spindle 5; the driving motor 4 is installed on the driving rotary support seat 2, and the driving spindle 5 is fixed on the output end of the driving motor 4;

[0019] a support assembly, including a tool spindle 6 and a tool spindle bearing seat 8; the tool spindle 6 is detachably connected with the driving spindle 5, the tool spindle bearing seat 8 is fixed on the outer circle of one end of the tool spindle 6, and the tool body 7 is detachably fixed on the outer circle of the tool spindle 6;

[0020] The quick-change assembly 9 comprises the auxiliary rotary support seat 3, a fixed chuck 91, a rotating shaft 92 and a quick-change chuck 93. The fixed chuck 91 is fixed in the auxiliary rotary support seat 3. The upper end of the auxiliary rotary support seat 3 is provided with a connecting lug. The rotating shaft 92 is rotatably arranged in the connecting lug. The quick-change chuck 93 is fixed on the rotating shaft 92.

[0021] The quick-change chuck 93 can be rotated under force. When the quick-change chuck 93 is rotated, it has two states of separation and closure with the fixed chuck 91. In the separation state, the replacement of the tool body 7 is performed. In the closure state, the replacement of the tool body 7 is not performed.

[0022] The two ends of the connecting lug are provided with insertion holes. The rotating shaft 92 rotates in the two insertion holes.

[0023] As a preferred embodiment, the fixed chuck 91 has a semicircular cross section. The quick-change chuck 93 also has a semicircular cross section. The tool spindle bearing seat 8 is movably arranged in a circular space formed by the quick-change chuck 93 and the fixed chuck 91. Threaded holes 931 are formed between the fixed chuck 91 and the quick-change chuck 93. The threaded holes 931 are detachably connected with clamping screws 94 through threads.

[0024] When the quick-change chuck 93 and the fixed chuck 91 are in the closure state, the clamping screws 94 are tightened to limit the tool spindle bearing seat 8 by the quick-change chuck 93 and the fixed chuck 91. The tool spindle 6 drives the tool body 7 to rotate synchronously with the driving spindle 5 to perform chip removal work.

[0025] When the quick-change chuck 93 and the fixed chuck 91 are separated, please refer to Figure 2 The clamping screws 94 are loosened and removed to release the limiting effect of the tool spindle bearing seat 8 by the quick-change chuck 93 and the fixed chuck 91. Then the quick-change chuck 93 is rotated upward to separate the quick-change chuck 93 from the tool spindle bearing seat 8. The tool spindle 6 and the tool spindle bearing seat 8 are moved to the right. After the tool spindle 6 and the driving spindle 5 are completely removed, the tool spindle 6, the tool spindle bearing seat 8 and the tool body 7 are completely removed to complete the integrated disassembly work. When the tool spindle 6, the tool spindle bearing seat 8 and the tool body 7 are integrated and installed, the above process is operated in reverse.

[0026] In summary, only one clamping screw 94 needs to be disassembled to complete the quick disassembly of the tool body 7 and the tool spindle 6 on the auxiliary rotary support seat 3.

[0027] As a preferred embodiment, the tool spindle 6 is fixed with a clamping flange one 61, the tool spindle 6 is slidably provided with a clamping flange two 62 on the circumferential wall, a plurality of through holes are provided on the tool body 7, a plurality of bolts 63 are respectively threadedly connected in the mounting holes of the clamping flange one 61 and the clamping flange two 62, and the plurality of bolts 63 respectively penetrate the plurality of through holes.

[0028] Specifically, please refer to Figure 4 When the tool body 7 is installed, the tool body 7 is sleeved into the tool spindle bearing seat 8 and moved to contact the right end face of the clamping flange one 61, then the clamping flange two 62 is sleeved into the tool spindle bearing seat 8 and moved to contact the right end face of the tool body 7, then the through holes are aligned with the mounting holes of the flanges, then the plurality of bolts 63 are sequentially penetrated through the through holes and the mounting holes, and then the plurality of nuts 64 are threadedly connected on the plurality of bolts 63, completing the clamping and positioning installation; when the tool body 7 is disassembled, the above process is reversed.

[0029] In the above, the outer diameter of the tool spindle 6 is greater than or equal to the outer diameter of the tool spindle bearing seat 8, so that the tool body 7 cannot pass through the tool spindle bearing seat 8.

[0030] In addition, a nut 64 is threadedly connected at the connection between each bolt 63 and the clamping flange one 61, and the nut 64 is attached with an elastic gasket to prevent damage to the tool body by rigid contact.

[0031] As a preferred embodiment, one end of the tool spindle 6 is fixed with a tapered mounting head, a tapered hole is provided at the end of the driving spindle 5, and the tapered mounting head is clamped in the tapered hole.

[0032] That is, when the tool is installed, the tapered mounting head needs to be inserted into the tapered hole, so that the driving spindle 5 drives the tool spindle 6 to rotate synchronously, and when the tool is disassembled, the tapered mounting head needs to be pulled out of the tapered hole, and the installation method of the tapered hole and the tapered mounting head is a prior art (for example, the installation method between the common motor shaft and the detachable transmission shaft), and the specific structure and principle are not described here.

[0033] As a preferred embodiment, the driving rotary support seat 2 and the auxiliary rotary support seat 3 are fixedly installed on the mounting rack 1, and the mounting rack 1 is fixedly installed on the machine tool, so that the chip work and the tool replacement work can be stably carried out.

[0034] In the specific application process, when the tool needs to be replaced, first, the driving motor 4 is closed, and after the driving spindle 5 stops rotating, the clamping screw 94 is twisted and removed, then the quick-change chuck 93 is turned to the upper side, the clamping action of the tool spindle bearing seat 8 disappears, at the same time, the quick-change chuck 93 is separated from the tool spindle bearing seat 8, then the tool spindle 7 and the tool spindle bearing seat 8 are moved to the right by a certain distance, ensuring that the tapered mounting head in the tool spindle 6 is completely separated from the tapered hole in the driving spindle 5, then the tool spindle 6 and the tool spindle bearing seat 8 are directly taken out, thereby realizing integrated disassembly, and after integrated disassembly, the tool can be disassembled again offline, specifically, the clamping flange two 62 and the tool body 7 are sequentially removed from the tool spindle 6, and the dismounting work of the tool body 7 is completed, and when a new tool body 7 is installed, the above process is operated in reverse, and thus the tool replacement work is completed.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
