1. Field of the Invention
The invention relates to holders and more particularly to a tools holder capable of increasing length by assembling at least one additional component (e.g., interconnecting member) between base and blade by using a technique similar to mortise and tenon joint.
2. Description of Related Art
CNC (computer numerical control) lathes are widely employed as technologies advance. The CNC lathes can perform cutting, drilling, etc. on a workpiece. For example, a lathe may be required to cut a workpiece by using one of different blades.
However, the conventional lathe is only equipped with a cutter having a fastening member and a blade integrally formed with the fastening member which is secured to a mounting groove of the lathe. Length of the blade is fixed, i.e., not being adjustable. This means that it only can cut a workpiece of limited thickness. Thus, a cutter having a longer blade is required to mount on the lathe if a workpiece having a greater thickness. However, such cutters are expensive and inevitably increase the manufacturing cost.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a tools holder comprising a base including a rear fastening member configured to secure to a mounting groove of a lathe, and a front groove member, and at least one hole extending from an outer surface to the groove member; a blade including a front cutting member and a rear tenon fitted into the groove member; and at least one fastener each driven through one of the at least one hole to urge against the tenon for fastening the base and the blade.
Preferably, further comprises at least one interconnecting member each including a rear tenon fitted into the groove member of the base, a front groove member for receiving the tenon of the blade, and at least one hole extending from an outer surface to the groove member thereof; at least one first fastener each driven through one of the at least one hole of the base to urge against the tenon of one of the at least one interconnecting member for fastening the base and one of the at least one interconnecting member together; and at least one second fastener each driven through one of the at least one hole of one of the at least one interconnecting member to urge against the tenon of the blade for fastening one of the at least one interconnecting member and the blade together.
Preferably, the groove member of the base is an annular groove.
Preferably, each of the at least one hole of the base is a threaded hole, and each of the at least one hole of each of the at least one interconnecting member is a threaded hole, each of the at least one first fastener is a threaded fastener, and each of the at least one second fastener is a threaded fastener.
Preferably, the tenon of the blade is shaped to fit into the groove member of the base.
Preferably, the tenon of each of the at least one interconnecting member is shaped to fit into the groove member of the base.
Preferably, the tenon of the blade is shaped to fit into the groove member of the base.
Preferably, the tenon of each of the at least one interconnecting member is shaped to fit into the groove member of the base.
It is envisaged by the invention that the tools holder is capable of increasing length by assembling at least one interconnecting member between the base and the blade by using a technique similar to mortise and tenon joint, thereby eliminating drawbacks (e.g., preparing blades of different length for cutting workpieces of different thickness, and increased manufacturing cost) of the cutter of the conventional lathe. Further, the assembly is secured due to complimentary engagement of any two adjacent components and the provision of threaded fasteners.
The invention, as well as its many advantages, may be further understood by the following detailed description and drawings in which:
Referring to
The base 10 includes a rear fastening member 11 adapted to secure to a mounting groove of a lathe, and a front groove member (or an annular groove) 12, and a plurality of holes (e.g., threaded holes) 13 extending from an outer surface to the groove member 12.
The blade 20 includes a front cutting member 21 and a rear tenon 22 shaped to fit into the groove member 12. A plurality of fasteners 90 are driven through the holes 13 to urge against the tenon 22 for fastening the base 10 and the blade 20 together. Preferably, the fasteners 90 are threaded fasteners.
In a second configuration (see
In a third configuration (see
It is envisaged by the invention that the tools holder is capable of increasing length by assembling at least one interconnecting member 30 between the base 10 and the blade 20 by using a technique similar to mortise and tenon joint, thereby eliminating drawbacks (e.g., preparing blades of different length for cutting workpieces of different thickness, and increased manufacturing cost) of the cutter of the conventional lathe. Further, the assembly is secured due to complimentary engagement of any two adjacent components and the provision of threaded fasteners 90.
Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
