Description
Technical field
The utility model relates to a kind of slot boring mechanism, particularly boring undercut groove mechanism.
Background technology
At metal works, such as, in aluminium recovery process, not easily process twice undercut groove, the mechanism structure of existing boring undercut groove is complicated, not easily manufactures, assembles, adjust loaded down with trivial details, adds and produces duration and production cost simultaneously.
Summary of the invention
The purpose of this utility model is to provide the boring undercut groove mechanism of simple, easy to manufacture, the easy to adjust and reliable in action of a kind of structure.
The technical scheme realizing the utility model object is as follows:
Boring undercut groove mechanism, comprise casing, also comprise cutter, boring bar, main shaft, countershaft, curve cam, bearing holder (housing, cover), bearing, bearing block, piston rod, cylinder body and motor, described motor is fixed on casing, described main shaft to stretch in casing and is connected with body pivot, described main shaft is connected by gear drive with motor, described countershaft stretches in main shaft, described countershaft is set with curve cam, one end that described countershaft stretches out casing is fixedly connected with boring bar, described boring bar is fixed with cutter, described bearing holder (housing, cover) is sleeved on main shaft, described bearing sleeve is contained on bearing holder (housing, cover), bearing is provided with in described bearing block, described main shaft is provided with the key that constraint bearing holder (housing, cover) axially moves, described bearing holder (housing, cover) is provided with pin, described pin stretches in main shaft, described cylinder body is fixed on casing, described piston rod by cylinder body from casing overhanging enter in casing, described piston rod is fixedly connected with bearing block.
Described boring bar is fixed a cutting tool and is provided with two.
Adopt after said structure, simple, easy to manufacture, the easy to adjust and reliable in action of the utility model structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is casing, 2 is cutter, and 3 is boring bar, and 4 is main shaft, and 5 is countershaft, and 6 is curve cam, and 7 is bearing holder (housing, cover), and 8 is bearing, and 9 is bearing block, and 10 is piston rod, and 11 is cylinder body, and 12 is motor, and 13 is key, and 14 is pin.
Detailed description of the invention
The utility model boring undercut groove mechanism comprises casing 1 as shown in Figure 1, cutter 2, boring bar 3, main shaft 4, countershaft 5, curve cam 6, bearing holder (housing, cover) 7, bearing 8, bearing block 9, piston rod 10, cylinder body 11 and motor 12, described motor 12 is fixed on casing 1, described main shaft 4 to stretch in casing 1 and is rotationally connected with casing 1, described main shaft 4 is connected by gear drive with motor 12, described countershaft 5 stretches in main shaft 4, described countershaft 5 is set with curve cam 6, one end that described countershaft 5 stretches out casing 1 is fixedly connected with boring bar 3, described boring bar 3 is fixed with two cutters 2, described bearing holder (housing, cover) 7 is sleeved on main shaft 4, described bearing block 9 is sleeved on bearing holder (housing, cover) 7, bearing 8 is provided with in described bearing block 9, described main shaft 4 is provided with the key 13 that constraint bearing holder (housing, cover) 7 axially moves, described bearing holder (housing, cover) 7 is provided with pin 14, described pin 14 stretches in main shaft 4, described cylinder body 11 is fixed on casing 1, described piston rod 10 by cylinder body 11 from casing 1 overhanging enter in casing 1, described piston rod 10 is fixedly connected with bearing block 9.
During utility model works, driven by motor main axis, when needs boring undercut groove, in unit head trend boring bar access aperture, pressure oil enters the right chamber of cylinder body, promotion piston rod travels forward, piston rod drives bearing block and bearing holder (housing, cover) to make it to slide axially forward along the key on main shaft, pin is driven to move axially in the curved groove of curve cam, curve cam is forced to rotate, and drive boring bar work relative to the rotation of main shaft, start stock removal action, be cut to when requiring the degree of depth, pressure oil enters again the left chamber of cylinder body, boring bar is reversely rotated, cutter is made to exit undercut groove, unit head is return, prepare next actuation cycle.
