Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable replaceable lathe fixedly mounted on a tool rest of a lathe,
A shank fixedly attached to the tool rest by forming a fitting groove having a cross section of a shape and a fitting hole formed at the front of the shank to form a coupling hole communicating with the fitting groove; And a fastening hole formed to have a cross-sectional shape and to be fitted into the fitting groove of the fitting fixing part and coming into tight contact with the fastening hole, the fastening hole passing through the fitting projection to correspond to the fitting hole, A mounting seat comprising a head to be formed; And a fastening bolt which is screwed to a fastening hole of the fastening bolt through the fastening bolt of the fastening bolt and fastens the fastening bolt fitted to the fastening bolt in the fitting fastening bolt, It is possible to complete replacement with other kinds of bites only by replacing and mounting the mounting work.
Description
The present invention relates to a detachable replaceable lathe, and more particularly, to a method and apparatus for mounting a detachable replaceable lathe, and more particularly, It is possible to quickly and accurately change the height of the workpiece and the center of the workpiece, thereby shortening the working time and improving the productivity, The present invention relates to a detachable replaceable shelf bite that does not cause deterioration in durability.
BACKGROUND ART Generally, a lathe includes a main shaft which is driven by a main shaft motor, a bed which is provided in front of the main shaft shaft, a reciprocating table provided on the upper side of the bed and including a tool table on which a cutting tool is mounted, It is made as a thrust which clamps one end of a long workpiece.
As shown in FIG. 1, the tool holder is mounted on the upper side of the carriage which is mounted on the upper side of the carriage and is moved in the X axis. The tool holder includes a base positioned at the lower portion and fixed to the carriage, A tool holder and a handle including a spiral shaft passing through the center of the base, wherein a mounting groove for mounting a bite is formed in the middle of the periphery of the tool holder, and on the upper side of the mounting groove, A plurality of bolts for pressing the bolts are fastened.
Therefore, when the cutting operation is performed using the above tool holder, first, the handle located on the upper side of the tool holder is rotated counterclockwise to release the tool holder from the base, and then the four It is possible to select a byte necessary for machining among the bites and position it to the machining portion side, and to rotate the handle in the clockwise direction to cut the fixed holder and proceed the cutting.
However, in the case of performing the cutting operation through the conventional tool bobbin configured as described above, the number of bites (3 to 4) provided on the tool bobbin is limited, and the machining efficiency of the machine tool is reduced.
In other words, since the installation of the bite required for machining is limited, it is necessary to replace the tool with a tool such as a bite or a knurling suitable for the type of machining operation. There is a problem in that time is consumed to perform the operation.
On the other hand, in recent years, when a tip provided on a bite is worn or damaged, a technique of replacing only a tip without replacing the entire bite has been devised through a public utility model publication.
However, the conventional bite holder for a lathe described above has a problem in that it can not be replaced with other types of bite tips suitable for the type of machining operation, as shown in Fig. 2, there was.
Therefore, when using the conventional technique, there is a problem that it is necessary to replace and install a suitable type of byte every time the type of the processing operation is changed. Due to the correction time of the height at the time of replacement installation for each type of byte, It takes a long time, and the operation time is delayed.
Thus, the applicant of the present invention has proposed a method of mounting a shank of a bite on a tool table by using a mounting fixture fixedly mounted on a tool table and a mounting bracket mounted on the fixture by forming a tip, .
The object of the present invention is to standardize the mounting work of the tip with the tip fixed to the tool holder so that it can be easily installed and replaced so that the height of the tool and the center of the workpiece, And which can be replaced, thereby shortening the working time and improving the productivity.
Further, in the present invention,
And the fitting protrusions of the mounting cradle fitting into the fitting grooves and brought into close contact with each other, The mounting cradle can be easily installed in the front, left, and right directions of the installation and maintenance unit, and the fitting protrusion of the combined mounting cradle can be kept in a state of being completely in close contact with the fitting projection of the mounting cradle The present invention has been made in view of the above problems, and it is an object of the present invention to provide a detachable replaceable shelf bite capable of preventing the occurrence of trembling during cutting processing, without deteriorating the performance and durability of the bite.According to an aspect of the present invention,
A shank fixedly attached to the tool rest by forming a fitting groove having a cross section of a shape and a fitting hole formed at the front of the shank to form a coupling hole communicating with the fitting groove; And a fastening hole formed to have a cross-sectional shape and to be fitted into the fitting groove of the fitting fixing part and coming into tight contact with the fastening hole and passing through the fitting projection to correspond to the fitting hole, A mounting seat comprising a head to be formed; And a fastening bolt which is screwed to a fastening hole of the fastening bolt through the fastening bolt of the fastening bolt and fastens the fastening bolt fitted to the fastening bolt in the fitting fastening bolt, Wherein the replaceable insert can be replaced with another type of insert only by replacing and mounting the insert.The replaceable lathe bite according to the present invention can be easily installed and replaced by standardizing the mounting position of the tool having the desired tip in the mounting and fixing part fixed to the tool holder. Therefore, even if the operator is not skilled, the height of the bite, It is possible to easily and promptly and precisely replace it, thereby reducing the working time and improving the productivity.
Further, in the present invention,
And the fitting protrusions of the mounting cradle fitting into the fitting grooves and brought into close contact with each other, The fitting cradle can be easily installed in the front, left, or right direction of the installation cradle, and the fitting protrusion of the combined mounting cradle can be kept in a state of being completely in close contact with the fitting protrusion of the fitting cradle It is a useful invention that does not cause deterioration in the performance and durability of the bite because no shaking occurs in the cutting process.1 is a perspective view showing a conventional tool stand;

As described above, after the assembly of the present invention is completed, the present invention is fixedly mounted on a tool post of a lathe. At this time, the portion fixedly installed on the tool rest is a mounting and fixing
In this state, the worker can rotate the main spindle and simultaneously move the tool bar provided with the present invention forward, backward, leftward and rightward through a transfer belt (not shown) to machine the workpiece into a desired shape, The upper and lower surfaces and the rear surface of the
On the other hand, usually, four bites can be provided on the tool post of a lathe. When a long tool such as a knurling tool is installed on the tool post, only two bytes can be installed on the tool post.
Therefore, it is necessary for the operator to replace the corresponding bite for the various operations such as roughing, finishing, grooving and screwing. In the present invention, So that it is possible to save time for replacement of the bite.
In other words, in order to replace the normal bite, the shank portion fixedly mounted on the tool holder must be unfixed and replaced with a whole beverage. However, according to the present invention, the
