Description
Technical field
It the utility model is related to a kind of leading screw thread protection mechanism, and in particular to single armed pen machine protects machine with leading screw thread
Structure.
Background technology
Single arm measurement lining instrument is a kind of device for being widely used in field of machining, and its main function is on workpiece
Line, reference is provided for the processing of workpiece.Single arm measurement lining instrument mainly by three-dimensional coordinates measurement rule main frame, scribing worktable,
Line part, digital display instrument, precise electronic gauge head system, Y-axis range lengthen a few part groups such as system and graphics process figure software
Into.Part of ruling includes line seat and marking-off pin, and line seat is arranged on Y-axis horizontal arm.
Single arm measurement lining instrument be a kind of light harvesting and it is electromechanical cross function chalker in the efficient of one, it can quickly, have
Complete to rule to complex partses and the three-dimensional of model element in effect ground.The precision of single arm measurement lining instrument and adjustment and product to be rule
The quality of production have a substantial connection, high-precision single arm measurement lining instrument is the important leverage for manufacturing high quality of products.
The volume of single arm measurement lining instrument is selected from tens cubic centimetres to several cubic metres for the part of different volumes
Select different size of lining instrument.When bulky lining instrument suspends in line, there can be larger inertia, and due to its volume
Greatly, the column of support level arm is higher, and when column suspends movement, the position apart from workbench farther out still can be along it thereon
Preceding movement locus continues to move.Because column lower end is connected with leading screw, fixed by leading screw, column is higher, column stop motion
When, its top inertia is bigger, and then is extremely stressed the connecting portion of column and leading screw, destroys column and the spiral shell on leading screw
Tooth, the measurement accuracy of pen machine is influenceed, reduce the service life of pen machine.
Utility model content
The utility model purpose is to provide single armed pen machine leading screw thread protection mechanism solve column pause movement
When, because column is too high, cause the connecting portion of column and leading screw to be extremely stressed, destroy column and the thread on leading screw,
Influence the measurement accuracy of pen machine, the problem of reducing the service life of pen machine.
The utility model is achieved through the following technical solutions：

Around axis of rotation, with the rotation of cam, the side wall of cam contacts with the side wall away from leading screw on column, and keeps contacting shape
State.Continue to keep former direction to move due to there is at the top of column cam to limit it, thus avoid excessive inertia at the top of column and
The situation that column produces very big stress with leading screw connecting portion occurs, and protects the thread of column and leading screw connecting portion, avoids
Thread damage and the situation that influences the measurement accuracy of pen machine occurs, improve the service life of pen machine；
2nd, the utility model single armed pen machine leading screw thread protection mechanism, controller according to pressure sensor transmission come
The power output of motor in pressure signal control drive component.When cam be pressed in the insufficient pressure on column with limit column this
End it is mobile when, then continue motor, be rotated further cam, until pressure sensor transmission come pressure meet the requirements,
Avoid the restraint of cam too small, cause the spacing inadequate situation of column to occur；
3rd, the utility model single armed pen machine leading screw thread protection mechanism, set gear component can only be right in column side
The motion in one direction of column is played spacing；Therefore need column both sides to be respectively provided with gear component, make column no matter leading screw which
Pause under individual direction movement, stop that column and the stress at leading screw connecting portion can be reduced in the presence of gear component.
