Description

A kind of cutter for milling machines more changing device
Technical field
The present invention relates to a kind of more changing device more particularly to a kind of cutter for milling machines more changing devices.
Background technique
In mechanical processing process, it usually needs replace different cutters, different cutters is required through knife bar come more It changes.During replacing cutter, need on cutter clamping to knife bar, it then again will be on knife bar clamping to clamping device.
Current more changing jobs often has two people to assist to complete, i.e., a people pins knife bar, and then another people passes through Dedicated spanner secures a cutter on knife bar.
Above-mentioned substitute mode needs two people to assist to complete, and human cost is larger.
Summary of the invention
In view of the above-mentioned problems, now providing a kind of use more convenient and fast cutter for milling machines more changing device.
Specific technical solution is as follows:
A kind of cutter for milling machines more changing device, has the feature that, comprising:
Pedestal is equipped with base installing hole at the bottom four corners of pedestal, and knife bar mounting hole and two cards are additionally provided on pedestal Block, fixture block are set on pedestal along the circumferential direction interval of knife bar mounting hole;And
Two can be used for clamping the clamping piece of knife bar, and clamping piece can reciprocatingly slide above and below along the short transverse of pedestal.
Above-mentioned cutter for milling machines more changing device, also has the feature that, more changing device further include:
Mounting cylinder, mounting cylinder are set on pedestal, and the side wall of mounting cylinder is equipped with two sliding slots, height of the sliding slot along mounting cylinder Direction is spent to be extended;
Adjusting block, adjusting block are arranged between two sliding slots, and adjusting block can short transverse along the chute reciprocatingly slide, press from both sides Piece is held on adjusting block;
Telescopic spring, Telescopic spring is set in mounting cylinder, and it is between adjusting block and pedestal;And
Guide rod, one end of guide rod sequentially pass through adjusting block, Telescopic spring and spiral and are connected on pedestal.
Above-mentioned cutter for milling machines more changing device, also has the feature that, the ring of clamping piece and fixture block along knife bar mounting hole It is successively staggered to direction.
Above-mentioned cutter for milling machines more changing device, also has the feature that, clamping piece is annular in shape.
The beneficial effect of above scheme is:
In cutter for milling machines provided by the invention more changing device, the fixed knife bar bottom of the fixture block to match with card slot on knife bar is utilized Portion clamps knife bar periphery wall using circular clamping piece, to prevent the shaking of knife bar in replacement process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cutter for milling machines more changing device provided in the embodiment of the present invention.
In attached drawing: 1, pedestal;2, base installing hole;3, knife bar mounting hole;4, fixture block;5, clamping piece;6, mounting cylinder;7, sliding Slot;8, guide rod.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art without creative labor it is obtained it is all its His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Fig. 1 is the structural schematic diagram of the cutter for milling machines more changing device provided in the embodiment of the present invention.As shown in Figure 1, this The cutter for milling machines provided in the embodiment of invention more changing device, comprising: pedestal 1 is equipped with pedestal at the bottom four corners of pedestal 1 and installs Hole 2, and knife bar mounting hole 3 and two fixture blocks 4 are additionally provided on pedestal 1, fixture block 4 is set along the circumferential direction interval of knife bar mounting hole 3 In on pedestal 1;And two circular clamping pieces 5 that can be used for clamping knife bar, and clamping piece 5 can be along the short transverse of pedestal 1 It reciprocatingly slides above and below.
In the present invention after pedestal 1 is fixedly mounted using base installing hole 2, knife bar can be passed through knife bar mounting hole 3 It sits and is set on pedestal, the fixed knife bar bottom of the fixture block 4 to match with card slot on knife bar i.e. available at this time recycles clamping piece 5 Knife bar 5 is clamped, cutter changing operation can be completed.
Knife bar periphery wall is clamped using circular clamping piece 5 in the present invention, to prevent the shaking of knife bar in replacement process.
Clamping piece 5 and fixture block 4 are successively staggered along the circumferential direction of knife bar mounting hole 3 in the present invention, so that working as knife Bar, which is sat, is set to the rear limit carried out using the clamping piece 5 being staggered and fixture block 4 to knife bar on circumferential direction, folder on pedestal It holds.
Specifically, more changing device in the present invention further include: mounting cylinder 6, mounting cylinder 6 are set on pedestal 1, and mounting cylinder 6 Side wall be equipped with two sliding slots 7, the present invention in sliding slot 7 by mounting cylinder 6 one end along the short transverse of mounting cylinder 6 be extended to It offsets with its other end;Adjusting block 8, adjusting block 8 are arranged between two sliding slots 7, and adjusting block 8 can along the chute 7 height side To reciprocatingly sliding, clamping piece 5 is set on adjusting block 8;Telescopic spring (not shown), Telescopic spring is set in mounting cylinder 6, and its position Between adjusting block 8 and pedestal 1;And guide rod 9, one end of guide rod 9 sequentially passes through adjusting block 8, Telescopic spring and spiral connects It is connected on pedestal 1, can first push adjusting block 8 before knife bar is installed in the present invention clamping piece 5 is fitted on pedestal 1, when by knife Adjusting block 8 can be unclamped when bar is packed on pedestal 1 and fixture block 4 is caught in card slot on knife bar, effect of the clamping piece 5 in Telescopic spring at this time Under go upward to 7 top of sliding slot.Knife bar periphery wall is carried out using the clamping piece 5 to match with knife bar periphery wall shape in the present invention Support prevents knife bar during cutter changing from shaking, and above-mentioned replacement operation only needs a people that can independently replace completion long.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention, right For those skilled in the art, it should can appreciate that and all replace with being equal made by description of the invention and diagramatic content It changes and obviously changes obtained scheme, should all be included within the scope of the present invention.
