Description
Technical field
The present invention relates to the device for boring that a kind of convenience is used at restricted clearance, belong to device for boring.
Background technology
Existing device for boring mainly be take 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 for some, be subject to the workpiece of space or volume restrictions, 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 problem to be solved in the present invention is to provide a kind of volume, and the boring that convenience that can be arbitrarily mobile is used at restricted clearance adds frock, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: the convenient device for boring using at restricted clearance, 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, at the other end of knife bar, is connected with pressing plate, on knife bar, between pressing plate and cabinet exterior, is provided with spring; At pressing plate, be provided with support set outward, support set is connected on casing, in the end of support set, offers screwed hole, 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 restricted clearance is that the position that connects cutter head on knife bar is provided with fixedly positioning sleeve and the screw of cutter head.
The device for boring that above-mentioned convenience is used at restricted clearance is to be provided with copper sheathing in the contact site of casing and knife bar.
The device for boring that aforesaid convenience is used at restricted clearance is, on the knife bar in casing, is socketed with plane bearing, and plane bearing is between turbine and cabinet wall.
Compared with the prior art, the present invention overcomes 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, at the other end applied thrust of knife bar, can complete feed.On knife bar, between pressing plate and cabinet exterior, be provided with spring, in the situation that losing external force, can guarantee 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 fixedly positioning sleeve and the screw of 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 guarantee that like this sealing in casing maintains easily again maintenance.
It is little that the present invention simultaneously also has volume, can arbitrarily move, and can meet the requirement that can carry out boring processing at small space; And because of simple in structure, make simple to operately, can make up workshop appliance working ability not enough; Reduce labor strength, cost-saving, and crudy is reliable; Be applicable to more on-the-spot space-constrained occasions.
Accompanying drawing explanation
Fig. 1 is mechanism map of the present invention.
In Fig. 1: 1. casing, 2. worm screw, 3. turbine, 4. knife bar, 5. cutter head, 6. positioning sleeve, 7. screw, 8. copper sheathing, 9. plane bearing, 10. spring, 11. pressing plates, 12. splicing sleeves, 13. feed screws, 14. cover plates.
The specific embodiment
Embodiment: as shown in Figure 1, be provided with the scroll bar 2 and the turbine 3 that cooperatively interact in casing 1, drive unit and worm screw 2 interconnect, and the cooperation of scroll bar 2 and turbine 3 can make the rotating speed of motor 1440r/min can be down to 30～50r/min; Therefore the fixed axis of turbine 3 is knife bar 4, is connected with knife bar 4 in its blowout patche, and knife bar 4 cooperatively interacts by key and keyway with the blowout patche of turbine 3, but the radial motion that can only limit both that coordinates of key and keyway does not limit the axially-movable of knife bar; The two ends of knife bar 4 are positioned at outside casing 1; In one end of knife bar 4, be connected with cutter head 5, the position that connects cutter head 5 on knife bar 4 is provided with fixedly positioning sleeve 6 and the screw 7 of cutter head; The other end at knife bar 4 is connected with pressing plate 11, and pressing plate 11 is bolted on knife bar morning, is socketed with spring 10, spring 10 on knife bar 4 between pressing plate 11 and casing 1 outer wall; Outside pressing plate 11, be provided with support set 12, support set 12 is connected on casing 1, in the end of support set 12, offers screwed hole, is connected with feed screw 13 on screwed hole, and feed screw 13 can be controlled knife bar 4 along turbine 3 axially-movables.For guaranteeing the sealing between casing 1 and knife bar 4 and being convenient for changing abrading section, in the contact site of casing 1 and knife bar 4, be provided with copper sheathing 8. and on the knife bar 4 in casing 1, be socketed with plane bearing 10, plane bearing 1 simultaneously) between turbine 3 and casing 1 inwall.
This device is screwed into cutter screw 13 with spanner and turns clockwise when feed, and pitch is 2mm, and spanner rotates a circle, and knife moves axially 2mm, during withdrawing, is rotated counterclockwise screw 13, utilizes the screen resilience of spring 10 that knife is exited.
