In the figure: the eccentric positioning device comprises an eccentric positioning sleeve 01, an eccentric round hole 02, a notch 03, a positioning groove 04, a threaded hole 05, a positioning screw 06, a guide column 07, a positioning key 08, a processing part 09 and a cutter 10.
Detailed Description
Referring to fig. 1 to 4, an embodiment of the present invention provides an eccentric positioning device for machining a key slot of a large-diameter inner hole of a broaching machine tool, including an eccentric positioning sleeve 01, wherein the eccentric positioning sleeve 01 is of an integrated structure. The diameter of the eccentric locating sleeve 01 is matched with the inner hole of the machined part 09 in the straight radial direction, an eccentric round hole 02 is formed in the middle of the eccentric locating sleeve 01, the inner diameter of the eccentric round hole 02 is matched with the diameter of a guide column 07 of a broaching machine tool, and the distance between the circle center of the eccentric round hole 02 and the circle center of the eccentric locating sleeve 01 is the depth of a key groove to be machined on the machined part 09, so that the problem that the depth of the key groove cannot be accurately controlled is solved. The eccentric locating sleeve 01 is detachably and fixedly arranged on a guide post 07 of a broaching machine tool, and one side of the eccentric locating sleeve 01 with the small wall thickness is provided with a notch 03 for a cutter 10 on the guide post 07 to pass through.
The inner wall of the eccentric inner hole of the eccentric positioning sleeve 01 is provided with a positioning groove 04, the positioning groove 04 and the notch 03 are arranged in an opposite mode, the size of the positioning groove 04 is matched with that of a positioning key 08 arranged on a guide column 07 of a broaching machine tool, the eccentric positioning sleeve 01 is sleeved on the guide column 07 of the broaching machine tool, the positioning key 08 on the guide column 07 of the broaching machine tool is embedded into the positioning groove 04, and therefore the relative position of the eccentric positioning sleeve 01 and the guide column 07 is positioned.
Threaded holes 05 which are consistent with positioning holes in a broaching machine tool guide post 07 are formed in two sides of the eccentric positioning sleeve 01, the threaded holes 05 penetrate through the eccentric positioning sleeve 01 and are communicated with eccentric round holes 02 formed in the eccentric positioning sleeve 01, and positioning screws 06 penetrate through the threaded holes 05 and the positioning holes to fix the eccentric positioning sleeve 01 and the broaching machine tool guide post 07.
