Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the jaw drive mechanism of the chuck in the prior art interferes with the rotation of the chuck, which affects the normal use of the chuck, thereby providing a stable, non-wearing, non-contact chuck. The disc rotation forms an interference, safer and more reliable driving mechanism that drives the moving part to move back and forth radially on the mounting seat

Embodiment 1

[0041] figure 1 It is a three-dimensional view of the driving mechanism provided in the first embodiment of the present invention for driving the moving part to move radially back and forth on the mounting seat, such as figure 1 Said, the driving mechanism for driving the moving part to move radially back and forth on the mounting seat provided by this embodiment includes: a toggle member, which is rotatably arranged relative to the mounting seat, and is positioned on the moving member corresponding to the toggle member. It rotates in a plane determined by the radial direction and the axial direction of the mounting seat, and is connected with the corresponding moving part; the drive assembly has a toggle connecting portion 41 which is consistent with the distribution of the toggle, so The toggle member is hinged to the corresponding toggle member connecting portion 41, and when the drive assembly moves back and forth in the axial direction of the mounting seat, the toggle member...

Embodiment 2

[0048] figure 2 Is a three-dimensional view of the chuck provided in the second embodiment of the present invention; image 3 for figure 2 Sectional view at middle A, such as figure 2 with 3 As shown, the chuck provided in this embodiment includes at least two jaws 1; the chuck body 2 is formed with radial grooves uniformly distributed on the disc surface, and each of the radial grooves is provided with one jaw 1. At least two of the claws 1 near the center of the chuck body 2 form a clamping opening, and the claws 1 can reciprocate along the radial groove to adjust the clamping diameter Size; and the driving mechanism described in the first embodiment for driving the moving part to move radially back and forth on the mounting seat, wherein the shifting part is the claw 1 and the mounting seat is the chuck body 2.

[0049] The driving mechanism is driven by the telescopic power to drive the claw 1 to move radially along the disk surface, and the clamping opening formed by the ...

Abstract

The invention discloses a driving mechanism driving moving pieces to move back and forth on an installation base in the radial direction and a chuck. The driving mechanism comprises stirring pieces and a driving assembly. The stirring piece can rotate relative to the installation base and rotate in the plane determined by the radial direction of the moving pieces corresponding to the stirring pieces and the axial direction of the installation base, and the stirring pieces are connected with the corresponding moving pieces. The driving assembly is provided with stirring piece connecting parts, wherein distribution of the stirring piece connecting parts is consistent with that of the stirring pieces. The stirring pieces are hinged to the corresponding stirring piece connecting parts. When the driving assembly moves back and forth in the axial direction of the installation base, the stirring pieces are driven to rotate to drive the moving pieces to move back and forth in the radial direction of the installation base. According to the driving mechanism driving the moving pieces to move back and forth on the installation base in the radial direction and the chuck, a mechanical transmission assembly is simple in structure, stable and reliable, and non-interference rotation of the chuck can be achieved.

Description

Technical field [0001] The invention relates to the technical field of workpiece clamping devices, in particular to a driving mechanism and a chuck for driving a moving part to move radially back and forth on a mounting seat. Background technique [0002] The chuck uses the radial movement of the movable jaws evenly distributed on the chuck body to realize the clamping and positioning of the workpiece. The chuck is usually installed on a lathe, cylindrical grinder or internal grinder. Common electric chucks, chucks The plate body is provided with a spiral coil wire, and the bottom of the jaw is provided with a thread groove that matches with the spiral coil wire. The motor drives the transmission shaft to rotate, and the transmission shaft drives the spiral coil wire to rotate, driving the jaws to move radially, but this kind of electric jaws The drive mechanism is not suitable for a rotatable chuck. Since the radial movement of the jaws is driven by the rotation of the spiral co...
