Abstract

The utility model relates to a collet chuck extension device which mainly comprises an extension collet chuck. The extension collet chuck comprises a clamping portion, a sleeve portion and an extension portion, wherein one end of the sleeve portion is connected to the clamping portion, the outer diameter of the sleeve portion is larger than the outer diameter of the clamping portion, the extension portion is columnar and connected to one end, opposite to the end where the sleeve portion is connected to the clamping portion, of the sleeve portion, the outer diameter of the extension portion is smaller than the outer diameter of the clamping portion, and the circumferential face of the extension portion is provided with more than one combination hole. According to the collet chuck extension device, an extension collet chuck contact head or an extension rod is connected and fixed on the extension portion, the length of the extension portion can be increased, when a tool is connected to machine, interference is not prone to happening, and the problem of high cost in tool rod replacement does not occur.

Description

The collet chuck extension fixture
Technical field
The utility model relates to a kind of anchor clamps of cutter, particularly a kind of collet chuck extension fixture.
Background technology
As shown in Figure 7, general existing cutter collet chuck 40 includes a grip shank 41, a sleeve 42 and a cutter chuck 43, this cutter chuck 43 can plug after pressing in conjunction with a cutter 50, and then is fixed on the knife bar with this grip shank 41, namely can carry out tapping processing.
But because the entire length of existing cutter collet chuck 40 is for fixing, if want to carry out the darker tapping operation of the workpiece degree of depth, must change long knife bar just can process, but usually change long knife bar and need higher cost, and the external diameter of this cutter collet chuck 40 is wider, and for the less tapping operation in aperture, easy and workpiece is interfered can't wholely enter hole, therefore, be improved in fact necessity of reinforcement.
The utility model content
Fix in order to solve existing cutter collet chuck length, the problem that is difficult for the dark or aperture that the aperture is less of working depth, main purpose of the present utility model is to provide a kind of collet chuck extension fixture, it is folded with extension at extending, make the prolongation collet chuck can utilize extension to install prolongation collet chuck chuck or the extension rod that prolongs usefulness additional, prolong whole length, with the how different process requirements of collocation.
The technological means that the utility model uses is to provide a kind of collet chuck extension fixture, includes:
One prolongs collet chuck, it includes a clamping part, a sleeve part and an extension, this sleeve part one end is connected in this clamping part, and the external diameter of this sleeve part is greater than the external diameter of this clamping part, this extension is column and is connected in the end that this sleeve part differs from this clamping part of connection, and the external diameter of this extension is less than the external diameter of this clamping part, and provided more than one combined hole at the side face of this extension.
Described collet chuck extension fixture, it further includes one and prolongs the collet chuck chuck, and this prolongation collet chuck chuck is connected and fixed on the extension of this prolongation collet chuck.
Described collet chuck extension fixture, it further includes an extension rod, and this extension rod is connected and fixed on the extension of this prolongation collet chuck.
Described collet chuck extension fixture, it differs from an end that connects this prolongation collet chuck at this extension rod and further is connected with a prolongation collet chuck chuck.
The collet chuck extension fixture that the utility model utilization provides, the effect that can obtain is improved and is:
1, extending of the present utility model is folded with extension, make the prolongation collet chuck can utilize extension to connect in addition for the extension rod that prolongs or prolongation collet chuck chuck, the utility model entire length is increased, be beneficial to carry out the darker workpiece processing of the degree of depth, produce interference and be unlikely with workpiece.
2, the utility model can utilize and prolong collet chuck in conjunction with extension rod or prolong the length that the collet chuck chuck extends cutter, does not need to change the longer but comparatively expensive knife bar of length, can reduce production costs.
