Abstract
The invention provides a tool holder. The tool holder comprises a tool bit and a tool bar. The tool bit is detachably connected with the tool bar. A blade mounting groove is formed in the front end of the tool bit. A pin shaft hole corresponding to a center hole of a blade is formed in the blade mounting groove. A square groove is formed in the periphery of the pin shaft hole. A pressing block is arranged in the square groove. The side face of the square groove is an inclined plane. The two side faces of the pressing block are provided with inclined faces with the inclination the same as that of the square groove. A groove is formed in the position, corresponding to the pin shaft hole, of the pressing block. A bolt fastening structure is arranged in the center of the pressing block. The portion, close to the groove, of the bottom end of the pressing block is provided with a jacking and pressing face in jacking and pressing fit with the peripheral face of the corresponding side of the blade. According to the tool holder, the tool bit and the tool bar are designed to be in movable connection, in this way, when tools of different functions are replaced, only the blade and the tool bit need to be placed, and the tool bar is universal, so that the utilization rate of materials is increased, and the cost of the tools is reduced greatly; and the pressing block is arranged on the tool bit, the blade fixing effect is good, and cutting efficiency is high.
Description
Technical field
The present invention relates to the turning tool rest in machining equipment, particularly to a kind of tool holder.
Background technology
The tool holder currently used is to be coordinated with screwed hole by bolt and fixed by blade, when needs more allowing blade replacement, it is necessary to bolt could be realized blade by back-outs whole in screwed hole and exited by bolt, the installation of blade, dismounting inconvenience very, structure is complicated, installs loaded down with trivial details.It addition, together with general tool holder, cutter head and knife bar be all integrally fixed at, need to tool holder entirety be replaced when changing the cutter of difference in functionality, so that cutter material waste is serious, utilization rate reduces, cost raising.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of tool holder, manufactures simply, is easily installed, dismantles, good economy performance, long service life.
nullFor solving above-mentioned technical problem，The technical solution used in the present invention is: a kind of tool holder，Including cutter head 1 and knife bar 2，Described cutter head 1 removably connects with knife bar 2，Described cutter head 1 front end is provided with blade installation slot 3，Described blade installation slot 3 is provided with the pin shaft hole 31 corresponding with the centre bore of blade，The periphery of described pin shaft hole 31 is provided with square groove 4，It is provided with compact heap 5 in described square groove 4，Described square groove 4 side is the plane being obliquely installed，Described compact heap 5 two sides are provided with the inclined-plane identical with square groove 4 gradient，Described compact heap 5 is provided with a groove 6 with pin shaft hole corresponding position，Described compact heap 5 center position is provided with bolt fastening structure，Described compact heap 5 bottom is provided with for the top pressure surface 7 with the respective side outer peripheral face top press-fit of blade near groove 6 place.
Further, one end of knife bar 2 has slotted eye 21, and top and bottom have screw, and the rear end face of cutter head 1 is provided with boss 11, and shape coordinates with slotted eye 21, boss 11 upper and lower surface has screw, is connected with knife bar 2 by screw.
Further, groove 6 is semi-circular recesses.
Further, the shape pushing up pressure surface 7 adapts with blade shapes.
Further, square groove 4 bottom land is higher than the bottom land of blade installation slot 3.
The present invention has the advantage that and has the benefit effect that a kind of tool holder, in the dismounting of blade and installation process, only need somewhat to unscrew, screwing bolts, all screw out without by bolt, the installation of blade, dismantle all very convenient, and the present invention is cutter head, knife bar is designed as flexible connection, owing to the function of cutter is different, the shape of blade is different, thus the shape of cutter head is different, so when changing the cutter of difference in functionality, can only more allowing blade replacement and tool bit part, knife bar can be general, the utilization rate of such material is improved, the cost of cutter also greatly reduces；Cutter head is provided with compact heap, blade good fixing effect, and stock-removing efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-Figure 2, a kind of tool holder, including cutter head 1 and knife bar 2, described cutter head 1 removably connects with knife bar 2, described cutter head 1 front end is provided with blade installation slot 3, described blade installation slot 3 is provided with the pin shaft hole 31 corresponding with the centre bore of blade, the periphery of described pin shaft hole 31 is provided with square groove 4, it is provided with compact heap 5 in described square groove 4, described square groove 4 side is the plane being obliquely installed, described compact heap 5 two sides are provided with the inclined-plane identical with square groove 4 gradient, described compact heap 5 is provided with a groove 6 with pin shaft hole corresponding position, described compact heap 5 center position is provided with bolt fastening structure 7, described compact heap 5 bottom is provided with for the top pressure surface 7 with the respective side outer peripheral face top press-fit of blade near groove 6 place.
One end of knife bar 2 has slotted eye 21, and top and bottom have screw, and the rear end face of cutter head 1 is provided with boss 11, and shape coordinates with slotted eye 21, boss 11 upper and lower surface has screw, is connected with knife bar 2 by screw.
Groove 6 is semi-circular recesses.
The shape of top pressure surface 7 adapts with blade shapes.
Square groove 4 bottom land is higher than the bottom land of blade installation slot 3.
The present invention is when actually used, first cutter head 1 and knife bar 2 are connected by screw, then blade is placed in blade installation slot 3, being placed in square groove 4 by compact heap 5, semi-circular recesses 6 is corresponding with pin shaft hole 31 position, and top pressure surface 7 is pressed with blade respective side outer peripheral face top, then bearing pin is utilized to be fixed by blade, utilize bolt fastening structure to be fixed by compact heap 5, finally tool holder is fixed on lathe tool seat, prepare stand-by.
The present invention separately designs blade, cutter head, knife bar into being flexibly connected, and blade is cutting tip, and rate of decay is the fastest, it is possible to only more allowing blade replacement, cutter head, knife bar can be reused；Owing to the function of cutter is different, the shape of blade is different, thus the shape of cutter head is different, so when changing the cutter of difference in functionality, it is possible to only more allowing blade replacement and tool bit part, knife bar can be general, the utilization rate of such material is improved, and the cost of cutter also greatly reduces；Cutter head is provided with compact heap, blade good fixing effect, and stock-removing efficiency is high.
Above embodiments of the invention are described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention.All equalizations made according to the scope of the invention change and improvement etc., all should still belong within this patent covering scope.
