Description
Technical field
This utility model relates to the technical field of CNC milling machine, a kind of clamping device for CNC milling machine.
Background technology
Traditional milling machine, during tool changing, utilizes manual operation carry out cutter locked fixing or unclamp dismounting, and work efficiency is low.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide the clamping device of a kind of auto lock and loosening cutter.
For achieving the above object, this utility model provides following technical scheme: a kind of clamping device for CNC milling machine, including main shaft and the Latin tapered sleeve that is fixed in described main shaft be set in helping pull a cart in Latin tapered sleeve, described main shaft is provided with and helps pull a cart reciprocating connecting rod for driving, described help pull a cart in be provided with several balls；Being provided with the installing hole for installing connecting rod in described main shaft, described installing hole includes hole, location, the first hole and the second hole being sequentially communicated, and the aperture in hole, location is more than the aperture in the first hole, and the aperture in the first hole is more than the aperture in the second hole.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that this utility model provides is brought: 1. cutter includes handle of a knife and drill bit, handle of a knife is provided with the annular groove adaptive with ball, when filling cutter, connecting rod drives to help pull a cart and moves upward, interior ball of helping pull a cart is ejected by the inwall of Latin tapered sleeve, makes ball just be opened on the annular groove of cutter, then ball just can be with clamping handle of a knife；When withdrawing, connecting rod drives to help pull a cart and moves downwardly to ball and can hide the position to circular cone, and cutter just can be pulled out easily, and then auto lock and loosening cutter.2. connecting rod needs at main shaft internal motion, therefore, being provided with the installing hole for installing connection bar in main shaft, described installing hole includes hole, location, the first hole and the second hole being sequentially communicated, and the aperture in hole, location is more than the aperture in the first hole, the aperture in the first hole is more than the aperture in the second hole, and the aperture in the second hole is identical with the external diameter of connection bar, the inwall in the first hole and the outer wall oil addition connecting bar, produce oil film, reduce frictional force when making connection bar drive, prevent mechanical wear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Cutting tool installation manner structural representation before main shaft.
Fig. 3 is Cutting tool installation manner structural representation after main shaft.
Detailed description of the invention
With reference to Fig. 1-Fig. 3, this utility model is described further.
A kind of clamping device for CNC milling machine, the Latin tapered sleeve 11 that including main shaft 1 and is fixed in described main shaft 1 and be set in Latin tapered sleeve 11 help pull a cart 12, described main shaft 1 is provided with and helps pull a cart 12 reciprocating connecting rods 13 for driving, and described helping pull a cart is provided with several balls 14 in 12；The installing hole 15 for installing connecting rod 13 it is provided with in described main shaft 1, described installing hole 15 includes the 151, first hole, hole, location 152 and the second hole 153 being sequentially communicated, the aperture in hole 151, location is more than the aperture in the first hole 152, and the aperture in the first hole 152 is more than the aperture in the second hole 153.
Cutter 2 includes handle of a knife 21 and drill bit 22, handle of a knife 21 is provided with and the annular groove 211 of ball 14 adaptation, when filling cutter, connecting rod 13 drives to help pull a cart and 12 moves upward, the ball 14 helped pull a cart in 12 is ejected by the inwall of Latin tapered sleeve 11, ball 14 is made just to be opened on the annular groove 211 of cutter 2, then ball 14 just can be with clamping handle of a knife 21；When withdrawing, connecting rod 13 drives to help pull a cart and 12 moves downwardly to ball 14 and can hide the position to circular cone, and cutter 2 just can be pulled out easily.
Wherein can be pumped by motor, hydraulic jack or air cylinder driven connecting rod 13.
Connecting rod 13 needs at main shaft 1 internal motion, therefore, the installing hole 15 for installing connection bar it is provided with in main shaft 1, described installing hole 15 includes the 151, first hole, hole, location 152 and the second hole 153 being sequentially communicated, the aperture in hole 151, location is more than the aperture in the first hole 152, the aperture in the first hole 152 is more than the aperture in the second hole 153, and the aperture in the second hole 153 is identical with the external diameter of connection bar, inwall in the first hole 152 and the outer wall oil addition connecting bar, produce oil film, reduce frictional force when making connection bar drive, prevent mechanical wear.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, those skilled in the art carries out common variations and alternatives in the range of technical solutions of the utility model all should be included in protection domain of the present utility model.
