Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of tool setting device, especially a kind of improved tool setting device.
Background technique
For lathe in turner, clamping workpiece is on chuck, the center line (centre of gyration line of claw) and vehicle of chuck
The center line of bed main shaft is coaxial, and lathe tool is mounted on knife rest, the center of workpiece end face of the point of a knife and clamping of lathe tool on chuck
It needs to be aligned, i.e., the point of a knife of lathe tool is contour with the centre of gyration of workpiece, this process is known as to knife, also referred to as to center height.
When to knife, need first to look for one vehicle crossed the workpiece of end face on chuck, vehicle crosses the workpiece of end face, end face turning it
Afterwards since the trace of lathe tool turning will form a central point, which is the centre of gyration of workpiece, then pacifies lathe tool
On knife rest, need by the point of a knife of lathe tool with the central point is contour is aligned, Lathe tool tip position is low or high to be passed through
It pads the edge bearing in lathe tool bottom to be adjusted, edge bearing has different thickness specifications, is adjusted by the stack combinations of edge bearing.It deposits
The problem of be, first, to knife when, need to preselect and prepare a vehicle and make the workpiece of end face, there are inconveniences；The second, lathe tool
Point of a knife whether be aligned with the end face center of workpiece, need to observe by the naked eye and judge, judgement be higher by or it is low go out amount, so
The edge bearing pad of respective thickness is gone for afterwards in lathe tool in the following, the amount for being higher or lower than central point due to visually observing point of a knife, judgement is not
Accurately, cause the unqualified thickness of looked for edge bearing suitable, need to adjust edge bearing repeatedly and pad thickness under lathe tool, influence dress knife
Speed.Third, clamping workpiece often exist when on chuck and fill askew phenomenon, the i.e. centre of gyration of the axis of workpiece and chuck
Line is not coaxial, and when chuck being caused to drive workpiece rotation, there are jumping phenomenas for workpiece end face, so that the central point and card of workpiece end face
The center line of disk is not contour, leads to that there are errors to knife.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, is proposed a kind of improved to knife dress
It sets, improves the high accuracy of Lathe tool tip centring, improve dress knife speed.
The purpose of this utility model can be realized by the following technical scheme: a kind of improved tool setting device, feature exist
In, including a clamping cylinder, clamping cylinder is interior to be provided with a shaft, the axis of shaft and clamping in such a way that axial restraint circumferentially rotates
The axis coaxle of cylinder, one end of shaft stretch out clamping cylinder and are fixedly connected with a measuring mechanism, and measuring mechanism includes template and amount
Ruler, template are in long plate shape, and the middle part side of template and the roller end for stretching out clamping cylinder are fixed, the other side of template with it is described
Gage is fixed, and the length direction of gage and the length direction of template are parallel, and the gage has scale value, the zero graduation of scale value
Point is contour with the center line of the shaft, and zero graduation point reads successively positive number to the direction of gage one end and increases, another to gage
Successively negative successively decreases the direction reading value at end, and the bottom end of the template is fixed with a clump weight；It is arranged and fixes in the shaft
There is a sleeve, the external cylindrical surface of sleeve offers mounting groove along its length, is fixed with level meter in the mounting groove.
Its working principles are as follows: clamping the outside cylinder of clamping cylinder by the claw of chuck by clamping cylinder clamping on chuck
Face, for template by the effect of clump weight gravity, template is in a vertical state, and the gage being fixed on template is also at vertical state,
Lathe tool is mounted on knife rest, follow rest, Lathe tool tip is close with gage, read Lathe tool tip quarter locating on gage
Angle value, due to the axis of shaft and the axis coaxle of clamping cylinder, the zero graduation point of scale value and the center line of the shaft are contour,
I.e. zero graduation point is also contour with the centre of gyration line of chuck jaws, i.e. the centre of gyration etc. of the workpiece of zero graduation point and institute's clamping
Height so that it is determined that whether centring is high for Lathe tool tip, and deviates the high distance in center, for example, Lathe tool tip is just aligned
Zero graduation point illustrates that point of a knife is targeted by center height, if being up higher by zero graduation point, illustrates point of a knife height, it is desirable to reduce edge bearing
Number illustrates that point of a knife is low if point of a knife is lower than zero graduation point down, needs to increase padded edge bearing, required to decrease or increase
The thickness of edge bearing be exactly Lathe tool tip from the difference that zero graduation point is read, it is known that the difference, so that it may increase or take out institute
The edge bearing of corresponding difference thickness, to keep the point of a knife centring of lathe tool high, the thickness of the required edge bearing increased or decreased can
It is measured by vernier caliper, edge bearing has the thickness of different size, can carry out independent assortment superposition, can also pass through vernier calliper
Ruler is folded to combined knife to carry out integral thickness measurement, so that its thickness is met the difference, then pad under lathe tool, make the point of a knife of lathe tool with
The contour alignment of zero graduation point, to keep Lathe tool tip centring high.The purpose that level meter is arranged is, in clamping clamping cylinder,
The axis coaxle for making the axis of shaft and the axis of clamping cylinder and chuck prevents the end face of shaft from there is bounce, thus the amount of preventing
The zero graduation point of ruler is beated, and improves the accuracy to knife, specifically used method is that rotating chuck to any position observes the water
Whether level is in horizontality, if the level meter is in non-standard state at this time, illustrates the axis and chuck jaws of shaft
Centre of gyration line is not coaxial, can unclamp claw slightly at this time, taps shaft or clamping cylinder with rubber hammer, level meter is made to be in water
Level state, similarly, rotating chuck carry out repeated detection, observe spirit level horizontal situation, and be adjusted to horizontality, this
When, the bounce of the zero graduation point of gage is eliminated in the axis of shaft and the axis coaxle of chuck, the bounce of elimination shaft end face,
Improve the accuracy to knife.
The both ends of above-mentioned clamping cylinder are open end, and bearing one is fixed in one end of clamping cylinder, is fixed in the other end
Bearing two, the shaft are threaded through in the inner ring of bearing one and bearing two and are secured to.So that clamping cylinder clamping is on chuck
When, template is kept gage in a vertical state always by the effect of clump weight gravity.
The end face that above-mentioned shaft stretches out clamping cylinder one end offers threaded hole, and the middle part side of the template is fixed with spiral shell
Bar, screw rod, which screws in threaded hole, fixes template with shaft.
Above-mentioned bearing one and bearing two are deep groove ball bearing.
Compared with prior art, the utility model has the advantage that
1. the utility model has the advantages that structure is simple, easy to use.
2. the utility model can accurately measure the difference in height of Lathe tool tip Yu the chuck centre of gyration, facilitate selection suitable
The edge bearing of thickness carries out pad knife, and alignment center is high, not only increases the accuracy to knife, also improves the speed of dress knife.
3. the utility model improves the accuracy to knife by the level meter of setting.
