Abstract

The utility model relates to a tool clamping rod in the field of machining. The clamping rod comprises an adjustment screw rod, an ejection rod, a tool rod, an ER elastic collet and an adjustment nut. The tool rod is a pipe-shaped rod, the inner wall of one end of the tool rod is provided internal threads correspondingly connected with the adjustment screw rod in a threaded mode, the outer wall of the other end of the tool rod is provided with external threads correspondingly connected with the adjustment nut in a threaded mode, and a tapered cavity corresponding to the ER elastic collet is formed in the ends of the external threads of the tool rod. The ejection rod is movably placed in an inner cavity of the tool rod. The inner side of the outer end of the adjustment nut is provided with a tapered hole correspondingly matched with a front tapered surface of the ER elastic collet. The clamping rod can achieve the purpose of being convenient to install, precise in positioning and convenient to replace on the premise that clamping precision is guaranteed.

Description

A kind of cutter supporting rod

[technical field]

The utility model relates to the machined field, especially relates to a kind of supporting rod of clamping cutter when carrying out the hole process operation for engine lathe or plain type numerically controlled lathe.

[background technology]

Known, restriction owing to fund reason or technical conditions, plain edition lathe and simple type numerically controlled lathe machining equipment are at home used shared large percentage in the total amount, and it generally all adopts " cubic type knife rest " or " row-knife knife rest " two kinds of cutter mounting means in application, yet, because what these two kinds of knife rests adopted is that vertical compression adds parallels or drill bit riveted way mounting cutter, therefore it not only has when the endoporus process operation inconvenience is installed, locate inaccurate defective, but also because its troublesome operation when changing cutter, caused engine lathe and simple cnc lathe to add that to have operation easier a man-hour bigger, the phenomenon that production efficiency is lower carrying out the hole.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model discloses a kind of cutter supporting rod, the purpose that described supporting rod can be issued to easy for installation, accurate positioning and be convenient to change in the prerequisite that guarantees the clamping precision.

For achieving the above object, the utility model adopts following technical scheme:

A kind of cutter supporting rod, described supporting rod comprise adjusting screw(rod), push rod, knife bar, ER elastic collet chuck and adjusting nut; Described knife bar is a tubular rod, and an end inwall of knife bar is provided with the internal thread with the corresponding wire connection of adjusting screw(rod), and the other end outer wall of knife bar is provided with the outer silk with the corresponding wire connection of adjusting nut, and the outer silk end termination of knife bar is provided with the conical cavity corresponding with the ER elastic collet chuck; Described push rod activity is positioned over the inner chamber of knife bar; The bellmouth with the inner cone corresponding matching of ER elastic collet chuck is established in inboard, described adjusting nut outer end.

Described cutter supporting rod, described adjusting screw(rod) silk head end end face is provided with interior square hole.

Described cutter supporting rod, described adjusting screw(rod) silk head end end face is provided with adjusting knob.

Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:

Cutter supporting rod described in the utility model is simple in structure, easy to use, it adopts the higher ER elastic collet chuck of positioning accuracy to come the clamping cutter, thereby has not only increased chucking power, guaranteed the clamping precision, the effect that has also played simultaneously easy for installation, accurate positioning and be convenient to change.

[description of drawings]

Fig. 1 is schematic diagram of the present utility model.

Among the figure: 1, adjusting screw(rod); 2, push rod; 3, knife bar; 4, ER elastic collet chuck; 5, adjusting nut; 6, internal thread; 7, outer silk; 8, conical cavity; 9, bellmouth.

[specific embodiment]

Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

1 described cutter supporting rod by reference to the accompanying drawings, described supporting rod comprises adjusting screw(rod) 1, push rod 2, knife bar 3, ER elastic collet chuck 4 and adjusting nut 5; Described knife bar 3 is a tubular rod, one end inwall of knife bar 3 is provided with the internal thread 6 with adjusting screw(rod) 1 corresponding wire connection, the other end outer wall of knife bar 3 is provided with the outer silk 7 with adjusting nut 5 corresponding wire connections, and the outer silk end termination of knife bar 3 is provided with the conical cavity 8 corresponding with ER elastic collet chuck 4, simultaneously, be provided with the bellmouth 9 with the inner cone corresponding matching of ER elastic collet chuck 4 in the inboard, outer end of adjusting nut 5, be an end and adjusting screw(rod) 1 wire connection of knife bar 3, after the other end of knife bar 3 and adjusting nut 5 wire connections ER elastic collet chuck 4 is fixed on this end, thereby the push rod 2 in knife bar 3 inner chambers is between adjusting screw(rod) 1 and the ER elastic collet chuck 4; For ease of adjust the position of push rod 2 in knife bar 3 inner chambers by adjusting screw(rod) 1, hexagonal hole or adjusting knob in can arranging at the silk head end end face in adjusting screw(rod) 1 outside, thus reach the convenient purpose that adjusting screw(rod) 1 rotates of adjusting.

When implementing cutter supporting rod described in the utility model, select the knife bar 3 of corresponding specification earlier according to lathe, knife bar 3 is fixed on the squaring head or row's cutter knife rest of lathe, select the ER elastic collet chuck 4 of corresponding internal diameter again according to the diameter of cutter, and be fixed on the respective end of knife bar 3 by the ER elastic collet chuck 4 that adjusting nut 5 will be with cutter, then by the other end of knife bar 3 push rod 2 of packing into, connect adjusting screw(rod) 1 at this terminal filament again, and making push rod 2 hold out against cutter by adjusting adjusting screw(rod) 1, last recycling adjusting nut 5 firm cutters have namely reached the purpose of fixed cutting tool; Because described supporting rod just can come multiple cutters such as Clamping Center brill, drill bit, boring cutter bar or locating bar by the ER elastic collet chuck 4 of changing corresponding internal diameter after once proofreading and correct, thereby not only reached the purpose of processing different parts, but also effectively reduced operation easier and improved production efficiency.

The utility model does not describe part in detail for prior art, so the utility model is not described in detail.
