Abstract

A mechanism for machining a workpiece includes a fixing base, a driving member, a connecting member, a cutter, a first guiding sleeve, and a spring. The driving member is positioned above the fixing base. The connecting member is coupled to the driving member. One end of the cutter is fixed to the connecting member, and the cutter is passed through the fixing base to machine the workpiece positioned under the fixing base. The spring is positioned between the connecting member and the fixing base. The spring is compressed when the driving member drives the cutter away from the fixing base to machine the workpiece, and the spring restores to bring the cutter back toward the fixing base after the machining.

First claim

What is claimed is:

1. A processing mechanism for machining a workpiece, the processing mechanism comprising:
a fixing base defining a receiving hole;
a driving member positioned above the fixing base;
a cutter, one end of the cutter being fixed to the driving member, and the cutter being adapted to be driven to move passing through the fixing base and to machine the workpiece positioned under the fixing base;
a connecting member coupled between the driving member and the cutter, the connecting member comprising a blocking portion extending out from an end portion of the connecting member adjacent to the driving member;
a first guiding sleeve mounted in an end portion of the receiving hole adjacent to the driving member;
a second guiding sleeve partially received in an end portion of the receiving hole away from the driving member; and
an elastic member positioned between the connecting member and the fixing base;
wherein the elastic member is compressed when the driving member drives the cutter to move away from the fixing base to machine the workpiece, and the cutter is adapted to be driven back to an original position by the compressed elastic member; and
wherein the first guiding sleeve comprises a flange extending out from an end portion of the guiding sleeve adjacent to the driving member, and two opposite ends of the elastic member are abutted against the flange of the first guiding sleeve and the blocking portion of the connecting member, respectively.

2. The processing mechanism of claim 1 , wherein the cutter movably passes through the receiving hole, and one other end of the cutter away from the driving member is adapted to be received in the receiving hole.

3. The processing mechanism of claim 1 , wherein the driving member comprises a driving base and a driving rod, the driving base is positioned above the fixing base, the driving rod is movably coupled to an end of the driving base toward the fixing base, and the connecting member is coupled to the driving rod away from the driving member.

4. The processing mechanism of claim 1 , wherein the first guiding sleeve and the second guiding sleeve are linear bearings.

5. The processing mechanism of claim 1 , wherein the connecting member further comprises a rod portion extending out from an end portion of the connecting member adjacent to the cutter, and one end of the cutter adjacent to the connecting member defines a coupling hole, the rod portion is inserted into the coupling hole, thereby the connecting member is coupled to the cutter.

6. A processing mechanism for machining a workpiece, comprising:
a fixing base defining a receiving hole;
a driving member positioned above the fixing base;
a first guiding sleeve mounted in an end portion of the receiving hole adjacent to the driving member;
a cutter, one end of the cutter fixed to the driving member, and the cutter being adapted to be driven to move pass through the fixing base and to machine the workpiece positioned under the fixing base;
a connecting member coupled between the driving member and the cutter, the connecting member comprising a blocking portion extending out from an end portion of the connecting member adjacent to the driving member, and a rod portion extending out from an end portion of the connecting member adjacent to the cutter; and
an elastic member positioned between the connecting member and the fixing base;
wherein the elastic member is compressed when the driving member drives the cutter to move away from the fixing base to machine the workpiece, and the cutter is driven back to an original position by the compressed elastic member;
wherein the fixing base defines a receiving hole, the cutter movably passes through the receiving hole, and an end of the cutter away from the driving member is adapted to be received in the receiving hole;
wherein one end of the cutter adjacent to the connecting member defines a coupling hole, the rod portion is inserted into the coupling hole, thereby the connecting member is coupled to the cutter; and
wherein the first guiding sleeve comprises a flange extending out from an end portion of the guiding sleeve adjacent to the driving member, and the ends of the elastic member are respectively abutted against the flange of the guiding sleeve and the blocking portion of the connecting member.

7. The processing mechanism of claim 6 , wherein the cutter movably passes through the receiving hole, and an end of the cutter away from the driving member is adapted to be received in the receiving hole.

8. The processing mechanism of claim 6 , wherein the driving member comprises a driving base and a driving rod, the driving base is positioned above the fixing base, the driving rod is movably coupled to an end of the driving base toward the fixing base, and the connecting member is coupled to the driving rod away from the driving member.

9. The processing mechanism of claim 6 , wherein the processing mechanism further comprises a second guiding sleeve, and the second guiding sleeve is partially received in an end portion of the receiving hole away from the driving member.

10. The processing mechanism of claim 9 , wherein the first guiding sleeve and the second guiding sleeve are linear bearings.
