Detailed Description

The following is a detailed description of a preferred embodiment of the utility model:

as shown in fig. 1 to 3, the tool clamping device includes a first clamping plate 1 and a second clamping plate 2, the first clamping plate 1 and the second clamping plate 2 are arranged in parallel, wherein a clamping head is arranged on the first clamping plate 1, an opening is arranged on the clamping head, and a clamping space 5 for clamping a corresponding tool holder 8 is formed in the clamping head.

Specifically, the chuck includes first clamping piece 3 and second clamping piece 4, first clamping piece 3 has first lateral surface and first medial surface, second clamping piece 4 has second lateral surface and second medial surface, first medial surface and second medial surface are just right each other, form jointly between the two centre gripping space 5.

The second clamping plate 2 is provided with a conical hole 7 corresponding to the first clamping plate 3 and the second clamping plate 4, the conical hole 7 is provided with a smaller end and a larger end, and the larger end is opposite to the first clamping plate 3 and the second clamping plate 4; under the assembled state of first splint 1 and second splint 2, first clamping piece 3 and second clamping piece 4 cover are established in bell mouth 7, first lateral surface and second lateral surface support and lean on the bell mouth 7 inner wall under the restriction of bell mouth 7 inner wall, constitute first medial surface and second medial surface are close to each other.

This cutter clamping device is when using, establish conical hole 7 with first clamping piece 3 and 4 covers of second clamping piece in, will correspond cutter handle of a knife 8 simultaneously and place in the centre gripping space 5 between first clamping piece 3 and second clamping piece 4, then compress tightly first clamping piece 1 and second clamping piece 2 from top to bottom, along with the relative displacement of first clamping piece 3 and second clamping piece 4 and conical hole 7 this moment, first clamping piece 3 and second clamping piece 4 support and can contract gradually by the 7 inner walls of conical hole of department, make first clamping piece 3 and second clamping piece 4 receive the effort of 7 inner walls of conical hole and be close each other, thereby compression centre gripping space 5 makes this cutter clamping device press from both sides tightly corresponding cutter handle of a knife 8.

Therefore, the cutter clamping device can lock the cutter without screws, can ensure that the cutter cannot be stressed to fall off, and ensures the safety of the machine cylinder and the grinding materials; meanwhile, the operation of locking screws is not needed, so that the operation is convenient, the labor is saved, and the processing efficiency is improved.

In the embodiment, the chuck is in a circular truncated cone shape, and the diameter of the cross section of the circular truncated cone is gradually reduced from one end connected with the first clamping plate 1 to the other end; this shape more closely matches the shape of the inner wall of the conical bore 7.

In this embodiment, the first inner side surface and the second inner side surface are two planes parallel to each other, and grooves 6 for accommodating corresponding tool shanks 8 are formed on the two planes; under two planes that are parallel to each other, the contact area between the corresponding cutter handle 8 and the cutter clamping device can be maximized, so that the corresponding cutter handle 8 can be clamped more stably and is not easy to fall off.
