Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a machining apparatus, which can prevent a workpiece from flowing during a polishing process by processing a workpiece formed in a curved or polygonal shape, such as a shift lever of an automobile, The time and the defective rate can be remarkably lowered.
A machining apparatus according to the present invention is an apparatus for machining a workpiece on which planar portions are formed on both sides and a machining portion formed in a curved or polygonal shape is formed between the planar portions,
A rotation guide portion that is fixed to one side of the workpiece and guides the rotation of the workpiece in place, a fixing portion that is symmetrical with the rotation guide portion with the workpiece interposed therebetween and surrounds and fixes the plane portion of the workpiece, And a polishing portion spaced apart from the polishing portion and polishing the processing portion of the workpiece.
Description
The present invention relates to a workpiece processing apparatus such as a shift lever of an automobile.
Generally, a workpiece such as a shift lever of an automobile is formed by a casting method and then machined.
In addition, burrs or the like are generated on the surface of such a work, and the bur reduces the performance of the automobile. Therefore, the worker directly removes the burr with a grinder or a separate grinding device.
However, when a worker directly removes a bur from a grinder, the work speed is very slow and the precision required for the product is high, which is not efficient.
In the case of a shift lever of an automobile, a curved or polygonal machining portion is formed on both sides of a quadrangular body. In the conventional grinding machine, the machined portion is polished while rotating the workpiece in the above- There is a problem that means for keeping the workpiece stably fixed during the process is not provided.
Therefore, in the conventional polishing apparatus, since the ball-shaped polishing unit is polished while rotating along the longitudinal direction and the upward and downward directions of the processing region of the workpiece, the machining completion time for one workpiece takes one minute or more, And the manufacturing cost per unit of the workpiece is increased.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a method of manufacturing a workpiece in a state in which a workpiece formed in a curved or polygonal shape, And it is an object of the present invention to provide a machining apparatus capable of significantly reducing machining time and defect rate.
A machining apparatus according to the present invention is an apparatus for machining a workpiece on which planar portions are formed on both sides and a machining portion formed in a curved or polygonal shape is formed between the planar portions,
A rotation guide portion that is fixed to one side of the workpiece and guides the rotation of the workpiece in place, a fixing portion that is symmetrical with the rotation guide portion with the workpiece interposed therebetween and surrounds and fixes the plane portion of the workpiece, And a polishing portion spaced apart from the polishing portion and polishing the processing portion of the workpiece.
Further,
A side fixing part spaced apart from each other by a predetermined distance and in contact with the flat part of the machining part, and a rear fixing part connecting the side fixing part and contacting the rear surface of the processing part,
And a receiving groove for receiving the machined portion is formed between the side fixing portion and the rear fixing portion.
The apparatus further includes a moving part connected to the fixing part and moving the fixed part so that the work piece moves in a direction in which the work piece is moved toward or away from the rotation guide part.
And a rotating portion for rotating the workpiece in place,
The rotation unit includes:
A rotating shaft connected to the moving unit, and a driving unit connected to the rotating shaft and rotating the rotating shaft in place.
The machining apparatus according to the present invention polishes a machining portion in a state in which a machining portion formed in a curved or polygonal shape such as a shift lever of an automobile is stably fixed through a fixed portion, Can be prevented from flowing due to the contact force between the abrasive part and the polishing part and the vibration force caused by the rotation of the abrasive part, thereby making it possible to drastically lower the defective rate of the processed workpiece and improve the productivity.
Further, since the polishing portion can be polished in a state in which the polishing portion is in contact with the entire machining portion of the workpiece, the machining time can be remarkably shortened.
