Abstract
Disclosed is a high-speed machinery main shaft cutter clamping device. The device comprises a hollow main shaft, a pull bar assembly and a pawl. The top end of the hollow main shaft is provided with a spacing structure. The inner cavity of the hollow main shaft is successively, from down to up, provided with a taper cavity for storing a taper cutter handle, a cutter holding cavity and a pull bar cavity. An elastic element is disposed between the hollow main shaft and the pull bar assembly. The elastic element is used for improving an upward elastic force for the pull bar assembly to allow the taper cutter handle to be pressed in the taper cavity. The bottom end of the pull bar assembly is connected with the pawl that can move downward into the cutter holding cavity along with the pull bar assembly. The pull bar assembly and the pawl are disposed inside the pull bar cavity. The pull bar assembly comprises a pull bar and a fine tuning member. The bottom of the fine tuning member is threadingly connected with the top of the pull bar. The top of the fine tuning member is abutted against the spacing mechanism. The bottom end of the pull bar is connected with the pawl. Since the pull bar assembly is provided with the fine tuning member, when an elastic force provided by the elastic element is not enough, the fine tuning member is adjusted to allow the elastic element to generate more deformation in order to achieve effects of elastic supplement.

Compared to existing technology, the beneficial effects of the utility model are: because rod assembly is provided with a trimming piece, therefore, when the elastic force that can provide at elastic component is not enough, can make elastic component produce more distortion by adjusting trimming piece, to reach, supplement flexible effect.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
The structural representation of a kind of high-speed mechanical main shaft cutter holding device that Fig. 1 the utility model provides,
1, hollow spindle; 2, pull bar; 3, trimming piece; 4, elastic component; 5, position limiting structure; 6, pulling claw; 7, bearing pin; 8, movable sleeve; 9, pull bar regulating block; 10, pull bar gland; 11, upper dish spring gland; 12, lower dish spring gland; 13, taper handle of a knife.
The specific embodiment
As shown in Figure 1, a kind of high-speed mechanical main shaft cutter holding device, comprises hollow spindle 1, rod assembly and pulling claw 6; Hollow spindle 1 top is provided with position limiting structure 5, and the inner chamber of hollow spindle 1 forms conical cavity, dress cutter chamber, the pull bar chamber that holds taper handle of a knife 13 from the bottom to top successively; Between hollow spindle 1 and rod assembly, be provided with and provide upwards elastic force so that taper handle of a knife 13 is pressed on the elastic component 4 of conical cavity for rod assembly, the bottom of rod assembly connects and can move down the pulling claw 6 that enters dress cutter chamber with rod assembly, and rod assembly and pulling claw 6 are placed in pull bar chamber; Rod assembly comprises pull bar 2 and trimming piece 3, and trimming piece 3 bottoms are threaded in the top of pull bar 2, and trimming piece 3 tops are connected on position limiting structure 5, and pull bar 2 bottoms connect pulling claw 6.
When work, rod assembly moves down together with pulling claw 6, and pulling claw 6 enters dress cutter chamber.Now, the taper handle of a knife 13 that cutter is housed can be placed in pulling claw 6.Then pulling claw 6 is under the effect of elastic component 4, follows rod assembly and moves up together and enter pull bar chamber, reaches pulling claw 6 and catches taper handle of a knife 13, and taper handle of a knife 13 is pressed on to the object of conical cavity.Because rod assembly is provided with a trimming piece 3, therefore, when the elastic force that can provide at elastic component 4 is not enough, can make elastic component 4 produce more distortion by adjusting trimming piece 3, to reach, supplement flexible effect.
