Description

  The present invention relates to a small vibration cutting and polishing apparatus that facilitates cutting and cutting of small parts and facilitates a series of processing operations by exchanging movable parts.

  Conventional machining of small parts can be done to some extent with existing power tools for vertical machining such as drilling parts, but for horizontal machining such as cutting and polishing for parts, Tools such as saw blades and files were performed manually by humans.

  However, in the conventional processing method, when the workpiece is not a flat plate but a cube or a U-shaped trihedron, the thread saw tool itself cannot be used, so that only the thread saw blade must be removed and used. At this time, the thread saw blade cannot sufficiently penetrate, so that the cutting stroke is shortened and the cutting operation is extremely difficult. In addition, there is a problem that the finish of the processing deteriorates because the tip of the thread saw blade hits the opposing cutting surface and scratches other than the cutting portion.

  FIG. 4 is an explanatory view of a machining method of a workpiece, which is one of the prior arts, in which holes are formed at four corners with an electric drill and opened using only a portion of a saw blade. Reference numeral 200 denotes a small cubic part, for example, for opening a small model window. For machining, holes 101 to 104 are made at four predetermined positions with a tool such as an electric drill, and then each hole is opened. The thread saw blade 301 is manually cut by humans between 101-102, between the holes 102-103, between the holes 103-104, and between the holes 104-101.

  Next, another conventional technique relating to such a workpiece processing method will be described. For example, an invention described in Patent Document 1 (Japanese Patent Laid-Open No. 2005-1042, title of invention “Cutting Method and Cutting Device”) is also known. In the invention shown in FIG. 2 of Patent Document 1, the cutting tool is moved with respect to the workpiece while being pseudo-rotated to cut the processed surface.

JP2005-1042

  However, the conventional manual processing method of FIG. 4 and the processing method of the optical element and the mold of Patent Document 1 also have problems. First, a method of making holes at four corners with a conventional electric drill and opening only by using a saw blade portion is widely adopted as a processing technique for workpieces. In a conventional processing method by manual work by a human, the workpiece 200 is, for example, a small model window is opened, and in processing, holes 101 to 104 are formed at four predetermined positions with a tool such as an electric drill. Then, the saw blade 301 is manually cut by a human hand between the holes 101 to 102, between the holes 102 to 103, between the holes 103 to 104, and between the holes 104 to 101. Next, it is common to complete the work by smoothing the cutting part with an abrasive and the cutting part manually by a human. At this time, in the case of a cube having a small depth or a U-shaped trihedron, there are problems such that the thread saw blade cannot be sufficiently penetrated and the cutting stroke is shortened, which makes it difficult to work.

  The prior art described in Patent Document 1 was also invented to process optical elements and molds with high precision, and the structure is extremely complex, so that the skill and expertise of the work are high. Is required. In addition, since the cutting apparatus itself is a fixed type, there is a problem that there is a limit to the degree of freedom of cutting and that it is larger, heavier, and expensive than a workpiece.

  As described above, the processing of the workpiece is used for manufacturing a small model, and various types of processing tools are employed. Whichever tool is used, the conventional machining method relies on human manual work. In addition, there is a cutting device for processing a scientific element, a mold, and the like with high accuracy, but there is a problem that it is a burden on the operator in terms of workability and cost for a workpiece.

  The present invention has been made in view of the above problems, and its purpose is to easily replace parts such as a saw blade and a file for horizontal machining such as cutting and polishing on a workpiece. An object of the present invention is to provide a device that operates electrically.

In order to solve the above problem, the device according to claim 1
A compact system that can easily perform a series of operations that require a workpiece while vibrating a working board equipped with a tool that can be exchanged according to the processing using a power supply unit and a rotation drive device. A vibration cutting and polishing apparatus was used.

Further, the device according to claim 2 is
In the small vibration cutting and polishing apparatus according to claim 1,
The cutting tool that can be exchanged is a small vibration cutting and polishing apparatus characterized by sawtooth and abrasive.

  According to such a device, even a small part such as a cube or a U-shaped trihedron, the cutting tool is replaced with a sawtooth during the cutting operation, and the cutting tool is replaced with a file of abrasive material for the polishing operation, and the workpiece is contacted. Thus, it is possible to provide a small vibration cutting and polishing device that can easily realize cutting and polishing.

It is the figure seen from the 1st invention upper surface for implementing this invention. It is the figure seen from the 1st invention side surface for implementing this invention. It is an upper view which shows the Example of the 1st and 2nd invention for implementing this invention. It is explanatory drawing at the time of cutting of a prior art.

  Then, the form for implementing this invention is demonstrated, referring FIGS. 1-3. FIG. 1 is a structural view of a small vibration cutting and polishing unit 20 as viewed from the top. A cutting tool 10 capable of replacement, an action board 12 capable of vibration, a rotating pulley 13 for smooth vibration action, And a main frame 11 on which a vibration shaft 14 as a center is mounted.

  FIG. 2 is a configuration diagram of the small vibration cutting and polishing unit 20 as viewed from the side. The main frame 11 is equipped with a rotation drive device 21 for vibrating and a power supply unit 22 for operating the rotation drive device. Yes.

  Further, as shown in FIG. 1, the rotation drive shaft 15 of the rotary pulley 13 is non-centered so that when the rotation drive device 21 is operated, the cutting tool 10 vibrates by an eccentric amount.

  Next, examples will be described. As shown in FIGS. 1 and 2, the small vibration cutting / polishing unit 20 is provided with a cutting tool 10 on an action board 12. When cutting, the cutting tool can be easily cut and polished by simply replacing the cutting tool with a sawtooth during the cutting work and replacing the cutting tool with a file that is an abrasive for polishing work and bringing it into contact with the workpiece.

  As described above, the small vibration cutting and polishing apparatus of the present invention replaces a cutting tool with a saw blade during cutting work and a cutting tool with a file of polishing material even for small parts such as cubes and U-shaped trihedral parts. In addition, cutting and polishing can be easily performed simply by contacting the machine parts, and work according to the application can be realized regardless of skill level and expertise, increasing the industrial utility value.
