Abstract
The utility model relates to a floating milling cutter, belonging to the milling cutter technology field. The technical problem to be solved is to provide a floating milling cutter which has good grinding effect and makes the milling cutter uniformly worn. The technical scheme adopted is that a bolt makes the milling cutter connected on a left end of a floating body through a pad; a transmission ring is sleeved on a right end of the floating body; a first pin is arranged in a groove of the right end of the floating body; a second pin is arranged in the bottom of an axial hole of a left end of a knife bar; one end of a tension spring is fixed on the first pin; the other end of the tension spring is fixed on the second pin; the flange in the central floating body has two symmetric through holes; two third pins are arranged in the through holes; ends of the third pins are inserted into the holes at the corresponding positions of a milling cutter end face, and the other ends are inserted into grooves in a transmission ring; a left end face of the knife bar has two symmetric holes; and ends of two fourth pins are inserted into holes in the left end face of the knife bar and the other ends are inserted into grooves in the transmission ring.
Description
Technical field
A kind of unsteady milling cutter of the utility model belongs to the milling cutter technical field.
Background technology
When grinding freezer compressor support crankshaft thrust face, at present milling cutters that use slotting cutter or do not float more.Use slotting cutter often not reach the surface roughness requirement of drawing requirement.Use the milling cutter that does not float,, add easily to produce man-hour and shake the requirement that does not also reach drawing because milling cutter can not all contact with surface of the work.And, because milling cutter and surface of the work, make milling cutter quick abrasion and wear and tear inhomogeneous for the part contacts.
The utility model content
The utility model overcomes the deficiencies in the prior art, and technical problem to be solved is for providing a kind of grinding effect good and can make the unsteady milling cutter that grinds the cutter uniform wear.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of unsteady milling cutter comprises: grind cutter, buoyancy body, transmission ring, knife bar, tension spring, bolt and pad, grind the cutter center and have through hole, the buoyancy body left end has screwed hole, and the buoyancy body right-hand member has groove, bolt will grind the left end that cutter is connected buoyancy body by pad, and transmission ring is sleeved on the right-hand member of buoyancy body;
First bearing pin is installed in the groove of described buoyancy body right-hand member, the left end of knife bar has axial hole, the bottom of described axial hole is equipped with second bearing pin, described buoyancy body is connected by tension spring with knife bar, one end of tension spring is fixed on described first bearing pin, and the other end of tension spring is fixed on described second bearing pin, the part that contacts of buoyancy body and knife bar, buoyancy body is set to protruding sphere, and knife bar is set to concave spherical surface;
Have the through hole of two symmetries on the flange at described buoyancy body middle part, two the 3rd bearing pins are installed in the described through hole, and an end of the 3rd bearing pin is inserted in the hole of grinding correspondence position on the cutter end face, and the other end of the 3rd bearing pin is inserted in the groove on the transmission ring; Have the hole of two symmetries on the left side of knife bar, an end of two the 4th bearing pins is inserted in the hole on the described knife bar left side, and the other end of the 4th bearing pin is inserted in the groove on the transmission ring.
The beneficial effect that the utility model is compared with prior art had is:
In the utility model, grind cutter and be installed on the buoyancy body, buoyancy body is installed on the knife bar by tension spring, and the contact-making surface of buoyancy body and knife bar is a sphere, has unsteady effect, when cutter contacted with workpiece, under the effect of workpiece, buoyancy body can drive ground cutter adjusting angle among a small circle, make and grind the better and surface of the work applying of cutter, reach requirement thereby the surface of grinding the back workpiece is slightly released souls from purgatory, and grind cutter can uniform wear, thereby prolonged the service life of grinding cutter.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 for grinding cutter, and 2 is buoyancy body, and 3 is transmission ring, and 4 is knife bar, and 5 is tension spring, and 6 is bolt, and 7 is pad, and 8 is first bearing pin, and 9 is second bearing pin, and 10 is the 3rd bearing pin, and 11 is the 4th bearing pin.
The specific embodiment
As shown in Figure 1, a kind of unsteady milling cutter of the utility model comprises: grind cutter 1, buoyancy body 2, transmission ring 3, knife bar 4, tension spring 5, bolt 6 and pad 7, grind cutter 1 center and have through hole, buoyancy body 2 left ends have screwed hole, and buoyancy body 2 right-hand members have groove, bolt 6 will grind the left end that cutter 1 is connected buoyancy body 2 by pad 7, and transmission ring 3 is sleeved on the right-hand member of buoyancy body 2;
First bearing pin 8 is installed in the groove of described buoyancy body 2 right-hand members, the left end of knife bar 4 has axial hole, the bottom of described axial hole is equipped with second bearing pin 9, described buoyancy body 2 is connected by tension spring 5 with knife bar 4, one end of tension spring 5 is fixed on described first bearing pin 8, and the other end of tension spring 5 is fixed on described second bearing pin 9, the part that contacts of buoyancy body 2 and knife bar 4, buoyancy body 2 is set to protruding sphere, and knife bar 4 is set to concave spherical surface;
Have the through hole of two symmetries on the flange at described buoyancy body 2 middle parts, two the 3rd bearing pins 10 are installed in the described through hole, one end of the 3rd bearing pin 10 is inserted in the hole of grinding correspondence position on cutter 1 end face, and the other end of the 3rd bearing pin 10 is inserted in the groove on the transmission ring 3; Have the hole of two symmetries on the left side of knife bar 4, an end of two the 4th bearing pins 11 is inserted in the hole on described knife bar 4 left sides, and the other end of the 4th bearing pin 11 is inserted in the groove on the transmission ring 3.
A kind of unsteady milling cutter of the utility model, during work, because the contact position of buoyancy body 5 and knife bar 4 is that sphere contacts, buoyancy body 2 is connected by tension spring 5 with knife bar 4, so when contacting with workpiece, under the effect of external force, buoyancy body 5 can drive grinds cutter adjusting angle among a small circle, thereby make and grind cutter 1 and better fit, the surface of workpiece is slightly released souls from purgatory reach requirement, and make that to grind cutter 1 wearing and tearing even with surface of the work.
