Specific embodiment
Of the invention is specifically explained as follows below:
The rotary monolever rocking bar feed system of bending of the present invention, the horizontal axis 1 including having bocca gear 2,1 one end of horizontal axis is set
It sets in rebound bearing shell 3, the other end is arranged bearing shell and multi-diameter shaft 5, and exposes the position expense hole 6 of ladder rotary table 8 in horizontal axis 1.
Spring back the both ends support knot bearing arrangement of bearing shell and bearing shell as horizontal axis.The bending of rotational handle 7 is divided into long bar portion and quarter butt portion, long
In 90-160 degree, quarter butt portion end sets screw thread for bar portion and quarter butt portion angle, matches after the pin hole 6 of quarter butt portion insertion horizontal axis 1 with nut
It closes, long bar portion is being equipped with rotary table 8 close to crooked place, and the bus of rotary table 8 and the central axis angle of stock free end are in 10-60 degree
In range, the bus of rotary table 8 is connect when the long bar portion of rotational handle 7 turns to the limit around quarter butt portion with the lateral surface of multi-diameter shaft 5
Touching.
The long bar portion of rotational handle is rotated using quarter butt portion as hinged shaft, and long bar portion turns to high-low limit position, stock
The outside face contact of the portion singly side of high rotary table and multi-diameter shaft 5, the lateral surface of multi-diameter shaft 5 rotate pole as limitation rotational handle
The limiting component of limit.
A scale slot 9 is set on bearing shell, it is scale axis, fixing axle and limit shaft that multi-diameter shaft 5, which there are three parts, and diameter gradually becomes
Greatly, multi-diameter shaft 5 sets graduated scale 10, the outer diameter and bearing shell of the multi-diameter shaft 5 where graduated scale 10 in the scale axis close to bearing shell position
Outer diameter is identical.Fixed axial inner opens screw hole to horizontal axis 1, and screw hole is interior to screw in rotation screw rod.The rotation screw rod is used for multi-diameter shaft
It is fixed with horizontal axis.Horizontal axis rotation drives graduated scale rotation, and the scale that the scale slot on bearing shell is directed toward is exactly under the spindle box driven
The size fallen, scale axis are contacted but are not attached to bearing shell adjacent side.
Horizontal axis 1 sets and opens screw hole on the end face of 6 side of pin hole, and screw hole extends to pin hole 6, and screw hole screws in handle screw.The structure
For the fixation of rotational handle, its specific position for resting on needs is controlled.The long bar portion of rotational handle and quarter butt portion bend position
The positioning convex ring in quarter butt portion is installed, it is fixed that positioning convex ring and quarter butt portion end nut carry out both ends to quarter butt portion jointly
Position stops quarter butt portion to slide in the axial direction in pin hole, and the end of the long bar portion of rotational handle 7 is equipped with balanced handle, spherical
It is connected between handle and rotational handle 7 using screw thread.
Rebound bearing shell 3 be that the circle that is vertically arranged is box-like, and side circle side is box cover, and axis hole is opened among another round side and is arranged
The end of horizontal axis 1, the end sides of horizontal axis 1 are provided with straight trough, disc spring 12,12 one end of disc spring are arranged in rebound bearing shell 3
It is fixed in the end face straight trough of horizontal axis 1,12 other end of disc spring is specified in inside rebound bearing shell 3, and disc spring 12 will drive
Horizontal axis 1 rotates.It is the main shaft upper rack that will cooperate with bocca gear on horizontal axis that disc spring 12, which drives the rotation trend of horizontal axis,
It drives upwards, is driven downwards after processing is completed in rotational handle, unclamp rotational handle, disc spring drives horizontal axis return.
The horizontal axis case of drilling machine is arranged in drilling machine equipped with the rotary monolever rocking bar feed system of bending, the feed system
Interior, bocca gear 2 and the rack gear of horizontal axis side in horizontal axis case cooperate on horizontal axis 1, the rebound bearing shell 3 and bearing shell at 1 both ends of horizontal axis
The left side and right side of horizontal axis case are set, and bearing shell and dial expose horizontal axis case.
The processing method of the rotary monolever rocking bar feed system of bending of the present invention
1, horizontal axis one end where traditional bocca gear is extended, processes a circular through hole in extended part, led to
The upper and lower opening in hole mills out plane, and the quarter butt end of insertion rotational handle, the long rod end of rotational handle can be in through-hole with quarter butt portion
Axis rotates within the scope of 20-160 degree；The one end of a straight trough for disc spring is processed on the end face of the other end of horizontal axis
It is fixed.
2, the production of monolever, by the bending of rotational handle, a length of 3-10 centimetres of quarter butt portion, bending angle 90-160
The both ends of degree, quarter butt portion and long bar portion process external threads, and the end of long bar portion is crin, another for fixing ball-type handle
End is filament, and effect is to prevent quarter butt portion from retracting during rotation the pin hole out that falls off with nut cooperation.
3, the circle processed outside one is arranged apart from bending part 1-4 centimeters in long bar portion in the rotary table production of rotational handle
Platform, rotary table have centre bore, and diameter is identical with handle shank diameter, and the centre bore of the long rod end insertion rotary table of rotational handle is simultaneously close
Cooperation, the central axis angle of the bus of rotary table and long bar portion is within the scope of 10-60 degree, and the larger circular bottom surface of rotary table is towards crin
End.The positioning spacer ring in quarter butt portion is process apart from 1-3 centimetres of bending place through cold-heading, positions the spiral shell of spacer ring and quarter butt portion end
Female fitness quarter butt portion is positioned.
Monolever solves the process of continuous work in the case where its rotation, and the Rotation Design of monolever then avoids in advance
The connection of the case where touching workpiece, conventional handle and handle set is that silk is connected, easy to damage, and is difficult to repair, and improves and set
The singlehanded shank of meter is to be very unlikely to damage with the connection of cylinder pin connection and transverse cross axis；The pole that monolever is rotated to body side
Limiting positioning method is the rotary table by welding on monolever to solve.
