Abstract
The utility model relates to a tool apron special for clamping long tool bar which comprises a tool apron body (2), an encircling hole (3), an adjusting groove (5), a jack screw (7) and a top hole (8). An encircling type clamping structure is adopted by the tool apron body, the encircling hole is formed in the tool apron body, a homodromous adjusting groove is cut in the tool apron body (2) to increase clamping force and reinforce fixing strength of a tool bar, a tool bit at the front end of the tool bar is prevented from generating vibration, efficiency and quality of mechanical machining are improved, and a long tool bar can be clamped. Meanwhile, the tool bar can be assembled and disassembled conveniently, loss of screws is reduced, and the tool bar can be protected well against deformation and generation of burrs.
Description
Technical field
The utility model relates to machining apparatus device, especially special metal long cutting tool bar clamping tool rest.The fixture of turning tool rod in machining.
Background technology
In current machining, the fixture of common knife bar is to take screw directly to hold out against knife bar, adopts some contact fixing, and the fixing of knife bar relies on the top power of screw terminal to fix completely, and mounting or dismounting are trouble, and knife bar and tool rest hole coordinate has relatively high expectations.This method can be fixed for short sword bar, but for metal long cutting tool bar, it is inadequate that the simple top power with screw terminal fixes, in this case, the easy tool setting masthead of holding screw goes out burr, or causes knife bar distortion, the cooperation in knife bar and tool rest hole is prone to loosening, this is because metal long cutting tool bar can produce larger torsion to tool rest, easily causes cutter head to produce vibration, affects Workpiece Machining Accuracy.
utility model content
The purpose of this utility model is to provide a kind of special metal long cutting tool bar clamping tool rest, rationally determines that knife bar and tool rest hole coordinate requirement, and effectively realize convenient mounting or dismounting with encircling type tool-apron structure.
The purpose of this utility model will realize by following technical measures: comprise tool rest, encircle hole, regulating tank, back down screw and apical pore; On tool rest, have and encircle hole, have regulating tank encircling between hole inwall and tool rest outer wall, on tool rest, have apical pore perpendicular to regulating tank direction, on apical pore, install and back down screw.
Especially, encircle hole axis parallel with regulating tank.
Especially, in the same direction, the length of regulating tank is not less than encircles hole depth.
Especially, on the side outer wall perpendicular to regulating tank direction tool rest, be evenly distributed with apical pore.
Especially, back down screw length and be greater than the apical pore degree of depth.
Especially, apical pore outer end is regulating tank one side on tool rest, and apical pore the inner is in regulating tank.
Advantage of the present utility model and effect: tool rest adopts encircling type clamping structure, and on tool rest, hole is embraced in open loop, and on tool rest 2, cuts a regulating tank in the same way, increase clamping force, strengthens the fixing dynamics of knife bar; Produce vibration with the cutter head that stops knife bar front end, thereby improve efficiency and the quality of machine cut processing, the knife bar of can clamping growing.Meanwhile, the convenience of mounting or dismounting knife bar, reduces the loss of screw, can protect preferably again not yielding the and grain raising of knife bar.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: knife bar 1, tool rest 2, encircle hole 3, fixing hole 4, regulating tank 5, set bolt 6, back down screw 7, apical pore 8.
The specific embodiment
The utility model principle is, adopts encircling type to fix according to theory of mechanics, can effectively increase contact-making surface, strengthens in conjunction with constant intensity, specifically should adopt and encircle hole and coordinate for the knife bar of circular shaft type.
The utility model comprises: tool rest 2, encircle hole 3, regulating tank 5, back down screw 7 and apical pore 8.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, have on tool rest 2 and encircle hole 3, have regulating tank 5 encircling between hole 3 inwalls and tool rest 2 outer walls, have apical pore 8 perpendicular to regulating tank 5 directions on tool rest 2, install and back down screw 7 on apical pore 8.
In aforementioned, encircle hole 3 axis parallel with regulating tank 5.
In aforementioned, in the same direction, the length of regulating tank 5 is not less than encircles hole 3 degree of depth.
In aforementioned, on the side outer wall perpendicular to regulating tank 5 direction tool rests 2, be evenly distributed with apical pore 8.
In aforementioned, back down screw 7 length and be greater than apical pore 8 degree of depth.
In aforementioned, apical pore 8 outer ends are regulating tank 5 one sides on tool rest 2, and apical pore 8 the inners are in regulating tank 5.
When the utility model work, the part of not opening regulating tank 5 on tool rest 2 has fixing hole 4, and set bolt 6 is fixed on tool rest 2 in frame by fixing hole 4.On tool rest 2, there are two apical pores 8, two pieces are backed down screw 7 and screw in apical pore 8, by backing down regulating tank 5, hole 3 internal diameters are encircled in expansion, knife bar 1 posterior segment is inserted and encircled behind hole 3, then, screw out to unclamp and back down screw 7, regulating tank 5 shrinks, and relies on tool rest 2 self material structure intensity fastening to encircle the face way of contact to knife bar 1 posterior segment.
In the utility model, tool rest 2 adopts newly-designed encircling type clamping structure, increases clamping force, strengthens the fixing dynamics of knife bar 1; On tool rest 2, hole 3 is embraced in open loop, and on tool rest 2, cuts regulating tank 5 connections in the same way and encircle hole 3 and tool rest 2 outer walls, and installs and back down screw 7 perpendicular to regulating tank 5 directions on tool rest 2, so both can lock knife bar 1, makes again the mounting or dismounting of knife bar 1 easy.Knife bar 1 and tool rest 2 adopt tight fit, produce vibration with the cutter head that stops knife bar 1 front end, thereby improve efficiency and the quality of machine cut processing, the knife bar 1 of can clamping growing.Meanwhile, the convenience of mounting or dismounting knife bar 1, reduces the loss of screw, can protect preferably again not yielding the and grain raising of knife bar.
