Furthermore, a plurality of connecting blocks and a plurality of lugs are arranged on the periphery of the end face of the dismounting seat, and the connecting blocks are circumferentially distributed at intervals around the central axis of the dismounting seat; the lug is arranged between every two adjacent connecting blocks; the concave positions are formed between the adjacent connecting blocks and the adjacent convex blocks at intervals; the connecting block with the installation casing can be dismantled and be connected.

Furthermore, the connecting block and the side wall of the lug, which are close to each other, are provided with guide inclined planes.

Furthermore, a plurality of first connecting holes are formed in the bottom end of the main shaft mounting position; the connecting blocks are provided with second connecting holes, the second connecting holes of the connecting blocks correspond to the first connecting holes one by one, bolts penetrate through the second connecting holes, and the tail portions of the bolts are screwed into the first connecting holes.

Compared with the prior art, the beneficial effects of the utility model reside in that: the dismounting seat can support the cutter, the cutter does not need to be held by hands, the dismounting tool is operated by hands, the dismounting interval formed between the dismounting seat and the main shaft mounting position stretches into the dismounting seat to be operated, the operation can be carried out by one hand, and the operation process is stable.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the detachable seat of the present invention.

In the figure: 10. installing a shell; 11. a main shaft mounting position; 20. disassembling and assembling the seat; 21. a penetrating port; 22. a concave position; 23. connecting blocks; 231. a second connection hole; 24. a bump; 25. a guide ramp; 30. and (7) assembling and disassembling intervals.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

the quick-dismounting structure of the spindle tool shown in fig. 1 and fig. 2 includes a mounting housing 10, a spindle mounting position 11 is provided on the mounting housing 10, a dismounting seat 20 is provided at a bottom end of the spindle mounting position 11, and the dismounting seat 20 is detachably connected to the mounting housing 10. In addition, the dismounting seat 20 is provided with a through port 21; and the dismounting seat 20 and the bottom end of the main shaft mounting position 11 form a dismounting interval 30 at an interval.

On the basis of the structure, use the utility model discloses a during main shaft cutter's quick assembly disassembly structure, can connect dismouting seat 20 on installation casing 10 and be located the bottom of main

shaft installation position

11, 11 mountable main shafts in the main shaft installation position on the above-mentioned installation casing 10, the tip of main shaft can stretch into dismouting interval 30, and the tool cooperation draws the claw by wearing interface 21 stretch into in dismouting interval 30, then dismouting seat 20 can bear the cutter, need not to hold the cutter with the hand, the hand operation assembly and disassembly tools (like spanner etc.), the dismouting interval that forms between dismouting seat 20 and the main shaft installation position 11 stretches into and operates can, but the tip at the main shaft is screwed up to the assembly and disassembly tools cutter, because dismouting seat 20 bearing stable in structure, because the clamping process is more stable, singlehanded alright operation.

Furthermore, a plurality of concave positions 22 can be arranged on the periphery of the dismounting seat 20, and the concave positions 22 are distributed around the circumference of the penetrating port 21 at intervals, namely, when clamping is carried out, tools such as a wrench can extend into the dismounting interval 30 from the concave positions 22 in different directions, so that the operation can be carried out from different directions conveniently.

Further, the periphery of the end surface of the mounting and dismounting seat 20 is provided with a plurality of connecting blocks 23 and a plurality of protruding blocks 24, the plurality of connecting blocks 23 are circumferentially distributed around the central axis of the mounting and dismounting seat 20 at intervals, and the protruding blocks 24 are arranged between two adjacent connecting blocks 23, so that the concave positions 22 can be formed at intervals between the adjacent connecting blocks 23 and the protruding blocks 24, the concave positions 22 do not need to be additionally processed, the connecting blocks 23 can be detachably connected with the mounting shell 10, and the mounting and dismounting of the mounting and dismounting seat 20 and the mounting shell 10 are facilitated.

Preferably, a guiding inclined plane 25 is further provided on the side wall of the connecting block 23 and the side wall of the protruding block 24 adjacent to each other, and the guiding inclined plane 25 can guide the assembling and disassembling tool into the concave position 22 for assembly.

Specifically, can be equipped with a plurality of first connecting holes in the bottom of main shaft installation position 11, and be equipped with second connecting hole 231 on connecting block 23, when the assembly, second connecting hole 231 and each first connecting hole one-to-one of each connecting block 23 of dismouting seat 20, afterwards, the cross-under has the bolt in second connecting hole 231, the afterbody spiro union of bolt is to in the first connecting hole, so, alright realize that the dismantlement of dismouting seat 20 and installation casing 10 is connected, the dismouting is more convenient.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
