detailed description

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given together with the accompanying drawings and described in detail as follows.

As shown in Figures 1 to 2, a quick clamping device for a cylindrical grinder includes a dial housing 1, a sliding sleeve 2, and a taper sleeve 3 arranged sequentially from the outside to the inside, and the inner side of the dial housing 1 is The wall is provided with a limit nail 4, and the outer wall of the sliding sleeve 2 is provided with a chute 5 slidingly matched with the limit nail 4, and the sliding sleeve 2 is detachably connected with the taper sleeve 3 through a set nail 6, and the dial The disc housing 1 is connected with the pulley of the main shaft of the head frame through the set nail 6 and drives the sliding sleeve 2 and the taper sleeve 3 to rotate together. The movable cavity formed by the sliding sleeve 2 and the taper sleeve 3 is pierced with a front spring 7. The head end of the top 8 is fixed on the machine tool, the tail end of the front top 8 runs through the front spring 7, and the taper sleeve 3 withstands the head end of the workpiece 10, and the tail end of the workpiece 10 is pushed against the tail end of the rear center 9, so The rear top 9 is provided with a rear spring; the machine tool, the rear top and the rear spring are all structures on the existing machine tool.

In the embodiment of the utility model, the rear top 9 and the rear spring are both arranged on the machine bed.

In the embodiment of the utility model, the elastic force of the rear spring is greater than that of the front spring 7 .

In the embodiment of the present utility model, the chute 5 is strip-shaped, and is arranged along the length direction of the sliding sleeve 2, and the inner diameter of the chute 5 is equal to the outer diameter of the stop nail 4; the chute 5 The number of preferably two, and set symmetrically, but not limited to this, according to the actual situation.

In the embodiment of the utility model, the front center 8 and the dial housing 1 are in clearance fit, so that the front center 8 and the dial housing 1 can move relative to each other.
