Machining apparatus
A machining apparatus capable of performing chamfering with high precision is provided. A machining unit 13 is provided at a distal end portion 12 a of an arm 12 of an articulated robot 11 , and the machining unit 13 includes a profiling roller 57 , which serves as a roller that abuts against a part to be profiled Wd of a workpiece W, and a rotatable tool 41 having an axis line 41 a having a distance between the rotatable tool 41 and the profiling roller 57 in conformity with a width of the workpiece W (width of a band-like portion Wc) and extending in parallel with an axis line 57 a corresponding to a support axis of the profiling roller 57 , and the rotatable tool 41 includes cutting blades 41 b or blade portions 73 and 73 as chamfering blades.
1. A machining apparatus for machining a workpiece including a surface to be machined at one side edge and a part to be abutted at another side edge, the machining apparatus comprising:
a profiling member having a reference surface that abuts against the part to be abutted so as to locate the workpiece;
a machining tool provided in such a manner that the workpiece is held between the profiling member and the machining tool, and in such a manner that a distance between the machining tool and the profiling member corresponds to a width of the workpiece;
a machining unit including a workpiece pinching jig including a pair of rollers, the machining unit is moved in a state that the workpiece is held between the pair of rollers such that the surface to be machined of the workpiece is machined by the machining tool;
a movable body on which the profiling member and the machining tool are both supported, wherein the movable body is slidably joined to a slider via a slide mechanism; and
a base body to which the slider is slidably joined via a further slide mechanism.
2. The machining apparatus according to claim 1 , comprising an actuator capable of varying the distance between the profiling member and the machining tool.
3. The machining apparatus according to claim 1 , wherein the profiling member is a roller.
4. The machining apparatus according to claim 1 , wherein an actuator is provided to slide the profiling member towards and away from the machining tool.
5. The machining apparatus according to claim 1 , wherein the pair of rollers is moved to open and close via a centering mechanism.
6. The machining apparatus according to claim 1 , wherein the machining tool is a rotatable tool.
7. The machining apparatus according to claim 1 , wherein the machining tool is a scraper.
8. The machining apparatus according to claim 1 , wherein the profiling member includes a roller, an axis of which extends in parallel with an axis line of the machining tool.
9. The machining apparatus according to claim 1 , wherein the machining tool is a rotatable tool including a pair of cutting blades.
10. The machining apparatus according to claim 9 , wherein the profiling member is a roller.
11. The machining apparatus according to claim 9 , wherein an actuator is provided to slide the profiling member towards and away from the machining tool.
12. The machining apparatus according to claim 1 , wherein the machining tool is configured to perform chamfering of the workpiece.
13. The machining apparatus according to claim 12 , wherein the pair of rollers is moved to open and close via a centering mechanism.
