Description
Technical field
It the utility model is related to lathe cutting tool apparatus field, more particularly to a kind of Telescopic cutter.
Background technology
In precision turning processing, the control key of dimensional tolerance is the precision of cross feed device, using dial,
Deceleration device and leading screw and nut mechanism realize Fine Feed, due to being limited by Crawl Mechanism, are difficult to realize accurate, micro adjustment
The amount of feeding of cutter.Therefore, it is necessary to realize the accurate micro-displacement of cutter using micro telescoping mechanism, in process pair plus
Work error makes corresponding compensation.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of Telescopic cutter, using piston
Principle, left and right logical hydraulic fluid port are connected with oil cylinder, and the flexible adjustment of cutter is realized by varying both ends cavity oil pressure, so as to stablize real
The micro-displacement feeding compensation of cutter in now processing.
Technical solution is used by the utility model solves its technical problem：
A kind of Telescopic cutter, including the capping of tool apron, knife bar, cutter head, drive end bearing bracket, rear end cap, afterbody and positioning pin；The knife
Head is installed on knife bar front end, and knife bar is installed in tool apron, and the both ends of tool apron set drive end bearing bracket and rear end cap to seal respectively, rear end cap
Be equipped with afterbody to cover, be equipped with left and right cavity between the knife bar and tool apron, left and right cavity respectively with corresponding tool apron top
The left and right logical hydraulic fluid port set communicates, and the knife bar is equipped with U-type groove, and positioning pin is installed in U-type groove.
Further, the cutter head is equipped with detachable blade.
Further, the positioning pin is fixed by screws on tool apron.
Further, the drive end bearing bracket and rear end cap are equipped with seal washer.
Further, the knife bar positioned at U-type groove both ends at tool apron cooperation with being respectively equipped with guide ring and seal washer.
Further, the tool apron bottom is equipped with dovetail groove.
The utility model has the advantages that：Installation positioning pin, can prevent knife bar with respect to tool apron in knife bar U-type groove
Rotate, and position-limiting action is played in movement in tool apron to knife bar；Detachable blade is set on cutter head, it is ensured that cutter head uses
In the service life, production cost is saved by more allowing blade replacement.
Brief description of the drawings
Fig. 1 is the utility model entirety sectional view.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in the figure：A kind of Telescopic cutter, including tool apron 1, knife bar 2, cutter head 3, drive end bearing bracket 4, rear end cap 5, afterbody capping 6
With positioning pin 7；The cutter head 3 is installed on 2 front end of knife bar, and knife bar 2 is installed in tool apron 1, and the both ends of tool apron 1 set front end respectively
Lid 4 and rear end cap 5 seal, and rear end cap 5 is equipped with afterbody capping 6, is equipped with left and right cavity between the knife bar 2 and tool apron 1, a left side,
Right cavity is communicated with the left and right logical hydraulic fluid port set at the top of corresponding tool apron respectively, and the knife bar 2 is equipped with U-type groove, in U-type groove
Positioning pin 7 is installed.
The cutter head 3 is equipped with detachable blade 31.
The positioning pin 7 is fixed on tool apron 1 by screw 41.
The drive end bearing bracket 4 and rear end cap 5 are equipped with seal washer.
The knife bar 2 positioned at U-type groove both ends at 1 cooperation of tool apron with being respectively equipped with guide ring 51 and seal washer.
1 bottom of tool apron is equipped with dovetail groove, is installed on by dovetail groove on lathe slide unit.
Specifically, when the left side on tool apron 1 leads to 11 oil inlet of hydraulic fluid port, the logical hydraulic fluid port 12 in the right side is fuel-displaced, and pressure oil enters the left sky of tool apron 1
In chamber 21, extruding knife bar 2 moves to the right, is stretched out to the right so as to fulfill cutter；It is same right to lead to 12 oil inlet of hydraulic fluid port, left logical hydraulic fluid port
11 is fuel-displaced, and pressure oil enters in right cavity 22, promotes knife bar 2 to be moved to the left, realizes that cutter is shunk to the left.In cutter telescopic process
In, realized when being moved to the limit in the U-type groove of knife bar 2 by positioning pin 7 it is spacing, prevent maloperation make cutter always unidirectionally into
Give initiation failure.The utility model can be controlled by hydraulic cylinder, the accurate microdisplacement feeding of cutter be realized, so as to improve
The machining accuracy of lathe.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.This reality
It is not restricted to the described embodiments with new, the above embodiments and description only describe the original of the utility model
Reason, the utility model also has various changes and modifications on the premise of not departing from the spirit and scope of the utility model, these changes
Change and improve and both fall within claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim and its equivalent define.
