Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

The specific embodiment of the present invention is such: referring to fig. 1-3, a clamping tool for drilling a cylinder part comprises a base 1, wherein a plurality of limiting pins 2 are arranged on one side of the base 1, the outer circular surfaces of the limiting pins 2 are circumscribed to a same common circumscribed circle, a cam wrench 3 for compressing a workpiece 9 is arranged on the other side of the base 1 in a position-adjustable manner, a plurality of positioning holes 4 uniformly distributed in the radial direction of the common circumscribed circle are arranged on the other side of the base 1, and pin shafts 5 matched with the positioning holes 4 are arranged on the cam wrench 3. The workpiece 9 is placed on the base 1, the workpiece 9 is of a stepped shaft-shaped structure, the cylindrical surface at the bottom of the workpiece 9 is abutted to the outer circular surfaces of the limiting pins 2, and the cam wrench 3 rotates by a certain angle to enable the cam of the cam wrench 3 to extrude the cylindrical surface of the workpiece, so that the workpiece 9 is pressed on the limiting pins 2, and the workpiece 9 is rapidly clamped.

In this tight frock of clamp of cylinder part drilling usefulness, outer disc through three spacer pin 2 and work piece 9 in close contact with carry out preliminary location to work piece 9, then press from both sides work piece 9 fast through rotating cam spanner 3 tightly, the location is accurate, and the drilling is stable, easy operation, and the selection of material is convenient, makes simply.

In this embodiment, the cam wrench 3 is a flat plate structure with a planar upper surface and a planar lower surface, a cam surface is arranged on one side of the cam wrench 3 close to the limit pin 2, the cam wrench 3 rotates stably, and the cam surface can extrude the workpiece 9.
