Description

Technical Field

[0001] The utility model relates to the technical field of ejector rods, in particular to an ejector rod with a simple replaceable ejector block. Background Art

[0002] In multi-axis machine tools, a push rod is used in the back-spindle chuck to push the processed parts out of the back-spindle chuck and let the parts fall into the feeding chute. For some parts made of soft materials, when the push rod pushes the parts out of the back-spindle chuck, it is very easy to cause damage to the contour surface of the parts. In order to prevent this phenomenon, there are strict requirements on the material, shape and specifications of the push parts.

[0003] In the prior art, the original ejector rod is made of a whole steel material, and the head is hard, which is easy to cause damage to the parts. Secondly, the ejector rod ejects the parts for a long time, which will cause friction on the top of the ejector rod. Therefore, when the top of the ejector rod needs to be replaced, the existing replacement method is relatively cumbersome, and it takes a long time to replace the ejector block on the ejector rod, which is time-consuming and labor-intensive, and reduces the processing efficiency of the parts. Therefore, a simple ejector rod with a replaceable ejector block is proposed. Utility Model Content
