The boring device capable of being used in the narrow and small space has the advantages of small size, capability of moving freely and meeting the requirements of boring in the narrow and small space; the structure is simple, thus the operation is simple, and the scarce processing capacity in a workshop of equipment can be made up.
Description
Technical field
The utility model relates to the device for boring that a kind of convenience is used at small space, belongs to device for boring.
Background technology
Existing device for boring is mainly taking boring machine as main, and its operating characteristic is that the boring that size of wanting workpiece etc. meets boring machine requires just can process.But be subject to the workpiece of space or volume restrictions for some, because workpiece can not meet the processing request of boring machine, cause it to adopt the higher miscellaneous equipment of processing charges by backward.
Summary of the invention
It is little that the technical problems to be solved in the utility model is to provide a kind of volume, and the device for boring that convenience that can be arbitrarily mobile is used at small space, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the convenient device for boring using at small space, it comprises casing, in casing, be provided with the scroll bar and the turbine that cooperatively interact, drive unit and worm screw interconnect, in the blowout patche of turbine, be connected with knife bar, the blowout patche of knife bar and turbine cooperatively interacts by key and keyway, and the two ends of knife bar are positioned at outside casing; One end at knife bar is connected with cutter head, is connected with pressing plate at the other end of knife bar, on knife bar, between pressing plate and cabinet exterior, is provided with spring; Be provided with support set outward at pressing plate, support set is connected on casing, offers screwed hole in the end of support set, is connected with feed screw on screwed hole, and feed screw can be controlled knife bar along turbine axially-movable.
The device for boring that above-mentioned convenience is used at small space is that the position that connects cutter head on knife bar is provided with positioning sleeve and the screw of fixing cutter head.
The device for boring that above-mentioned convenience is used at small space is to be provided with copper sheathing in the contact site of casing and knife bar.
Aforesaid convenience small space use device for boring be, on the knife bar in casing, be socketed with plane bearing, plane bearing is between turbine and cabinet wall.
Compared with the prior art, the utility model is to overcome the shortcoming that existing boring machine volume is large, be inconvenient to move, and its transmission and speed change adopt worm geared mode to design, and worm-drive can realize the transmission between alternating axis; Transmission is larger, and the geometric parameter of choose reasonable turbine, worm screw just can dwindle the volume of borer, thereby overcomes the restriction of locus.For realizing the feed of Boring machine processing process, in the blowout patche of turbine, connect knife bar, knife bar is realized both radial motions with turbine by key and coordinating of keyway, but its not limit key slip in keyway; Again, on the basis of mechanism, can complete feed at the other end applied thrust of knife bar.On knife bar, between pressing plate and cabinet exterior, be provided with spring, in the situation that losing external force, can ensure like this return of knife bar, also can control the axial gap of knife bar simultaneously.The position that connects cutter head on knife bar is provided with positioning sleeve and the screw of fixing cutter head, and this mechanism can be convenient for changing different cutters; Contact site at casing and knife bar is provided with copper sheathing, can ensure that like this sealing in casing maintains easily again maintenance.
It is little that while the utility model also has volume, can arbitrarily move, and can meet the requirement that can carry out boring processing at small space; And make simple to operately because of simple in structure, can make up workshop appliance working ability deficiency; Reduce labor strength, cost-saving, and crudy is reliable; Be applicable to more on-the-spot space-constrained occasions.
Brief description of the drawings
