Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a workpiece mounting table for various machine tools such as grinders and metal cutting machines, which can reduce the burden on the workpiece and tools and improve the work efficiency of the machine. Or it relates to a workpiece support.

0002

BACKGROUND OF THE INVENTION Conventionally, many machine tools have been used for performing various processing operations, such as grinding machines, metal cutters, milling machines, etc., and they come in a wide variety of types. These machine tools generally place the workpiece on a mounting table (table) and move the workpiece to the position of a tool such as a blade to cut, cut, grind, etc., or fix the workpiece. The method used is to move the tool to the required position and perform the work as appropriate.

0003

[Problem to be solved by the invention] However, in conventional machine tools, the relationship between the workpiece and the tool is constant, and no matter which part is moved, the workpiece is firmly fixed on the mounting table or workpiece holder. The tool is not deformed as much as possible, and the tool is subjected to a large impact during machining, causing damage to the tool and workpiece due to excessive pressure.It also makes a lot of noise, making it difficult to use it for various machining operations under optimal conditions. Excellent machine tools are not provided.

The present invention has been made in view of the above points, and is capable of reducing damage to tools and workpieces by buffering unreasonable pressure during machining in various machine tools, and enabling smooth machining at any time. It is an object of the present invention to provide a workpiece mounting table or a workpiece support part for a machine tool that can increase the work speed and improve the work efficiency.

[0005]

[Means for Solving the Problems] The gist of the present invention to achieve the above object is to provide a workpiece mounting table or a workpiece support portion that is capable of absorbing shocks caused by the workpiece in various machine tools that perform various types of workpieces. A workpiece mounting table or workpiece support portion of a machine tool is characterized in that the workpiece mounting table or workpiece support portion is formed of an elastic member that cushions the vibration.

[0006]

[Function] As described above, the workpiece mounting table or workpiece support part of the present invention can have so-called cushioning properties during machining, has relief against large pressure, and can be used with blades, drill polishers, etc. It can sufficiently absorb the pressure applied to tools and various workpieces, and minimize damage to tools, workpieces, motors, belts, etc. In addition, the noise generated during machining can be absorbed by the elastic member and reduced, and the elastic member does not apply excessive force to the tool or workpiece during work, making cutting, cutting, etc. smooth. This improves work efficiency.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings.

FIG. 1 is a partial side view showing a workpiece mounting table portion of the present invention, and FIG. 2 is a partial side view showing a workpiece support portion of the present invention.

In the drawings, reference numeral 1 denotes a workpiece mounting table on which a workpiece A is placed and worked with a tool B, and is made of urethane (urethane foam), rubber (foamed rubber),
It is made of elastic members such as styrene (urethane foam), various types of sponges, floating metal plates, coil springs, leaf springs, air cushions, and plate-shaped coils. Reference numeral 2 denotes a workpiece support section, which supports the workpiece and allows machining to be performed with the tool B, and is formed of an elastic member similarly to the workpiece mounting table 1 described above. Particularly in the case of a machine tool such as a jigsaw in which the support part 2 is small, it may be made of elastic or flexible plastic or metal, as long as the support part has elasticity with respect to the workpiece. In addition, even if the workpiece mounting table 1 and the workpiece support part 2 are entirely formed of an elastic member, the elastic member may be partially arranged (for example, on the surface part) to impart elasticity to the workpiece. It does not matter if the structure has
The elastic member is also not specified, and the point is that it may be a mounting table or a support part that provides cushioning properties to the workpiece during machining and reduces undue pressure on the tool. In addition, the elastic member has a structure in which the elastic modulus can be changed by appropriate means, and a workpiece mounting table 1 and a workpiece support part are equipped with a microcomputer or the like to provide an optimum degree of cushioning so that no unreasonable pressure is applied to the tool. It is also possible to form 2. Further, the elastic member may be tightened vertically using a die or the like, and the hardness and elasticity of the elastic member may be adjusted depending on the degree of tightening, and may be adjusted as needed depending on the type of workpiece.

Reference numeral 3 denotes a roll prevention guide, which is disposed around or inside the workpiece mounting table 1 (or workpiece support part 2) made of an elastic member, and the guide is fixedly installed on the machine body side. This is a stable guide that prevents the workpiece mounting table 1 from swinging laterally due to pressure applied to the mounting table during machining.

FIG. 3 is a partial side view showing a workpiece mounting table 1 in which a hard part 4 made of a hard member is laid on the upper surface (or surface) of a mounting table main body made of an elastic member. This prevents the elastic member of the workpiece from digging into the elastic member due to the pressure of tools, etc. during machining, and allows the workpiece to slide or move smoothly, further improving usability and work efficiency. I can do it. The hard member of the hard part 4 is made of glass, plastic, Teflon,
Materials such as stainless steel and iron can be considered, but are not particularly limited. Also, although not shown, the workpiece support section 2
Similarly, the hard part 4 may be laid on the top or surface of the support body made of an elastic member.

[0012] By removably attaching an elastic member having a buffering effect to the workpiece mounting table and workpiece support portion of the conventional machine tool using attachment means such as double-sided tape, screws, and fasteners, the same effect as in the above embodiment can be achieved. Moreover, if attached to a conventional workpiece mounting stand and workpiece support so that the elastic member and the hard member are positioned in a stacked state as illustrated in FIG. 3, a more effective machine tool can be achieved. can be provided.

[0013] Furthermore, in a conventional workpiece mounting table or a workpiece mounting table formed from an elastic member, the mounting table may be formed into a curved shape with a slightly raised center, or the center may be thinner and the peripheral portion may be thicker. By forming the back side of the table into a concave curved shape, it is possible to give the mounting table itself elasticity and cushioning properties.

[0014]

As explained above, according to the present invention, with respect to various machine tools used for various types of machining such as cutting, cutting, and grinding, unreasonable pressure is not applied to the tool due to movement of the workpiece during machining. This reduces damage to the tool and workpiece, and furthermore, since the workpiece has a buffering property against extreme pressure, the tool does not force any forced machining movements at all, allowing for extremely smooth machining. It can increase the working speed, and much of the noise generated during machining is absorbed by the elastic member and can be suppressed to a small level, which has great effects that cannot be achieved with conventional machine tools. , it can be said that the commercial value of the present invention is very high since it is widely used in various machine tools.
