Abstract
The utility model relates to a special tool for cutting an inside figure-eight groove of sleeve type parts which is used for the walking cutter frame arranged on a machine tool. The utility model is characterized in that a cranking handle is poked with the rotation of a lathe chuck, the cranking handle drives a driving bevel gear and a clamping chuck to rotate synchronously, and then, a driven bevel gear is rotated, a crank link mechanism is composed of the driven bevel gear, an eccentric shaft which is arranged on the driven bevel gear and a connecting rod, and the rotation is finally converted into the reciprocating linear motion of cutter rods and cutters. The cutting motion is compounded with the autologous rotational motion of the sleeve type parts and the reciprocating motion of cutters, and the cutting result is the inside figure-eight groove.
Description
The utility model belongs to the forming technique field, is a kind of cover parts splayed inside groove cutting specific purpose tool that uses on the lathe that is contained in.
Machining cover parts splayed inside groove---as the interior Eight characters oil groove of bearing shell, in machining, often run into, its processing method mainly contains two kinds: a kind of is manual cutting, and it is suitable for single-piece work, needs the quite high skilled worker of technical merit just can carry out; Second kind is lathe grinding, owing to there is not specific purpose tool at present, the workman of operation lathe must be very meticulously and masterful technique, because it mainly by the workman soon manually and Control Shaft to radially tool motion, speed is slow, the product processed quality is uneven, the more production of incompatibility bulk article.
The purpose of the utility model just is to remedy above technical deficiency, and provides fast, the easy to operate cover parts splayed inside groove that uses on the lathe that is contained in of a kind of process velocity to cut specific purpose tool.
The purpose of this utility model is achieved in that a kind of cover parts splayed inside groove cutting specific purpose tool, comprise: cutter head (1), knife bar (2), crank (3), driving bevel gear (4), driven bevel pinion (5), eccentric shaft (8), connecting rod (7), pitman (8), holding screw (9), base (10), it is characterized in that: be fixed with a crank of stirring by lathe chuck (3) on the driving bevel gear (4), eccentric shaft (6) is contained on the driven bevel pinion (5), and driven bevel pinion (5), eccentric shaft (6) and connecting rod (7) are formed a cover crank linkage.In order to adapt to the processing of different cover parts, the axially-movable distance of cutter should be adjusted, so eccentric shaft (6) is designed to adjustable with the eccentric throw in driven bevel pinion (5) axle center, in fact this regulated the distance of knife bar (2) linear reciprocating motion, pitman (8) is contained in the rear portion of knife bar (2) simultaneously, connected mode between them also removably connects, and is convenient to regulate the active length that knife bar (2) head stretches out.During use, cover parts is clamped on the chuck of lathe, this specific purpose tool is fixed on the feed support of lathe, the chuck of lathe is done gyration and is promptly stirred crank (3) rotation, driving bevel gear (4) rotates thereupon, driving driven bevel pinion (5) again rotates, by driven bevel pinion (5), the toggle that eccentric shaft (8) and connecting rod (7) are formed is changed into reciprocating motion with rotation, be that pitman (8) and knife bar (9) do reciprocating linear motion, do gyration by cover parts like this, the compound motion that cutter does reciprocating linear motion and forms, its cutting result is a splayed inside groove.
Adopt the utility model will obtain following effect:
1, this specific purpose tool provides power by lathe chuck, so the synchronized movement of motion of this specific purpose tool and lathe is coordinated.
2, process velocity is fast, crudy is reliable.
3, this specific purpose tool is fixed on the feed support of lathe, and is easy to operate.
4, in the process, simple to operate, the workman easily grasps.
5, the utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structure diagram.
Fig. 2 is the vertical view of the toggle be made up of driven bevel pinion (5), eccentric shaft (6) and connecting rod (7) among Fig. 1.
As shown in the figure, base (10) is the main body that connects each main parts size of the utility model: have an axially extending bore in the middle of it, be used to penetrate knife bar (2), constraint knife bar (2) and knife bar (2) can be done reciprocating linear motion in the hole; Its left end stretches out a spindle nose concentric with the knife bar hole, is used to install driving bevel gear (4), constraint driving bevel gear (4) and driving bevel gear (4) can be rotated on this spindle nose; A spindle nose vertical with the knife bar hole is stretched out on its top again, be used to install driven bevel pinion (5), constraint driven bevel pinion (5) and driven bevel pinion can be rotated on this spindle nose, another effect of base (10) is this specific purpose tool can be connected with the feed support of lathe, so a step is stretched out in its bottom, have 4-8 through hole on the step, people can be fastenedly connected this specific purpose tool on the feed support of lathe with bolt and nut by these holes.Cutter head (1) is a cutting tool, and it is fixed on the head of knife bar (2).Knife bar (2) is a long shaft rod, and it can do reciprocating linear motion in the through hole of base (10), and its head end that cutter head (1) is housed can put in the cover parts inner chamber of being processed always.Crank (3) is a L shaped bar, and its one is fixed on the driving bevel gear (4), and its effect is to stir crank (3) by means of the rotation of lathe chuck and drive driving bevel gear (4) to rotate synchronously with chuck.Driving bevel gear (4) is a bevel gear, be installed on the spindle nose of base (10) left end, it passes to driven bevel pinion (5) with gyration, driven bevel pinion (5) is one and driving bevel gear (4) axis normal and intermeshing bevel gear, it is installed on the top spindle nose of base (10), it changes direction and angle with gyration, and simultaneously it is formed one with eccentric shaft (6), connecting rod (7) mounted thereto and overlaps the crank linkage.Eccentric shaft (6) is a minor axis, its lower end is connected with driven bevel pinion (5), its upper end is hinged with connecting rod (7), its central axis up and down is parallel with the axis of driven bevel pinion (5) and one section eccentric throw arranged, this eccentric throw is adjustable, shown in the figure is to have a dovetail groove radially on the driven bevel pinion (5), and the lower end of eccentric shaft (6) just clamps in this dovetail groove.One end of connecting rod (7) and eccentric shaft (6) are hinged, the other end is then hinged with pitman (8), the toggle of driven bevel pinion (5), eccentric shaft (6) and connecting rod (7) composition changes the gyration of driven bevel pinion (5) reciprocating motion of pitman (8) into like this, the lower end of pitman (8) is fixed on the rear portion of knife bar (2) by means of holding screw (9), has also just driven knife bar (2) and has done reciprocating linear motion in the hole.The size that also can find out eccentric throw has thus just determined the straight-line distance of knife bar (2).
Therefore when the cover parts of need processing is done gyration on lathe chuck, the cutter on the knife bar (2) will do reciprocating linear motion in cover, and like this, what cutter cut in cover will be a splayed inside groove.Need to prove that this specific purpose tool must be fixedly mounted on the feed support of lathe, the tool setting in the processing, cutting output adjustment, withdrawing are finished by means of the operation of feed support.
Claims (2)
1, a kind of cover parts splayed inside groove cutting specific purpose tool, comprise: cutter head (1), knife bar (2), crank (3), driving bevel gear (4), driven bevel pinion (5), eccentric shaft (6), connecting rod (7), pitman (8), holding screw (9), base (10) is characterized in that:
Be fixed with a crank of stirring by lathe chuck (3) on A, the driving bevel gear (4),
B, eccentric shaft (6) are contained on the driven bevel pinion (5),
C, driven bevel pinion (5), eccentric shaft (8) and connecting rod (7) are formed a cover crank linkage.
