Description

Device for measuring cutting-tool wear of numerical control machine tool

The utility model relates to measurement mechanism in a kind of cutting tool for CNC machine abrading machine.

The processing dimension that tool setting device can not measuring workpieces in the used numerically-controlled machine machine of existing market and the degree of wear of cutter, especially after the basic-cutter wearing and tearing, again tool changing must be set coordinate system with loaded down with trivial details trial cut workpiece method, the method promptly wastes time and energy, precision is poor again, is the key factor that influences numerically-controlled machine throughput rate.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple and reasonable, but the processing dimension of measuring workpieces and tool wear degree, and tool setting speed is fast, the interior measurement mechanism of the cutting tool for CNC machine abrading machine that precision is high.

The purpose of this utility model is achieved in that

One jacking block 5 of being pulled dop 8 location, guide screw 13 guiding and being matched with housing 3 ante-chambers by hand is housed in housing 3 ante-chambers of rectangular bar shaped, be equipped with one in the jacking block 5 leading section chambeies and pull the handle of a knife 11 that gauge head 10 is equipped with in dop 9 location, front end by hand, be shaped on internal thread in the jacking block 5 rearward end chambeies and be meshed with the screw mandrel 6 that is communicated with housing 3 front/back cavities, be fixed with a spiral gear 2 that can be meshed on the screw mandrel 6 in housing 3 back cavities with worm screw 17, worm screw 17 and housing 3 sides are outer manually revolve 21 fixing.

Perpendicular to handle of a knife 11 axis one screw mandrel 12 that is meshed with handle of a knife 11 internal threads is arranged, this screw mandrel 12 and housing 3 are outer manually revolves 22 and fixes.

Between jacking block 5 rear ends and housing 3 ante-chambers one butterfly spring 4 is arranged on screw mandrel 6, in the jacking block 5 leading section chambeies and 11 on handle of a knife a butterfly spring 25 is respectively arranged on screw mandrel 12.

Advantage of the present utility model and good effect are:

1. simple and reasonable.X to (being that screw mandrel 6 is axial) by manually revolving a rotary worm, the spiral gear transmission, screw mandrel promotes jacking block and moves forward, and can make gauge head reach Precision trimming.Z by manually revolving a rotary screw rod, makes gauge head Z to fine setting to (being that screw mandrel 12 is axial).

2. precision height, X can reach 0.0005mm to precision; Z is to reaching 0.005mm, and this precision can satisfy request for utilization fully;

3. tool setting speed is fast, only finds the benchmark of this device, can be fast to the benchmark of good other lathe tool, and this once gets final product;

4. can judge by measuring tool wear whether the workpiece processing size is qualified, thereby reach the purpose of indirect examining workpieces;

5. manufacturing is simple, cost is low.

Description of drawings:

Fig. 1 is the utility model structure cut-open view;

Fig. 2 is Figure 1A-A cut-open view;

Fig. 3 is Figure 1B-B cut-open view;

Fig. 4 is Fig. 1 C-C cut-open view.

Below in conjunction with accompanying drawing the utility model embodiment is further described:

There are ante-chamber and back cavity and housing to be rectangular bar shaped in the housing 3, the jacking block 5 that is slidingly matched with it is housed in ante-chamber, this jacking block is by groove 7 location of palm dop 8 by making on the jacking block relevant position that are contained on the housing, lead by a logical gathering sill 15 that passes through by the guide screw 13 that is contained in the housing lower end in jacking block lower end system, the guiding position of guide screw is square and is slidingly matched with gathering sill that guide screw is by lock-screw 14 lockings.Jacking block front end face centre has a chamber, handle of a knife 11 by manual spanner 9 location is housed in this chamber, the handle of a knife end is fixed with gauge head 10, the middle-end in jacking block centre becomes an axis to be shaped on a circular hole with the rear end with handle of a knife, be shaped on the internal thread that is meshed with the screw mandrel 6 that is communicated with chamber, housing front and back in the circular hole of jacking block rear end, the butterfly spring 4 of an elimination thread pitch is arranged on this screw mandrel between jacking block rear end and housing ante-chamber.Be fixed with spiral gear 2 in the housing back cavity on screw mandrel, this spiral gear is meshed with worm screw 17 under it, and this worm screw is a low-modulus worm, and worm screw 21 fixes by outer manually the revolving of axle bed 20 and housing side.The screw mandrel end is positioned on the housing rear end by in the fixing axle bed 1 of stop screw 19, and housing back cavity bottom is by base plate 18 envelope positions, and screw 16 is fixing.

Have an internal thread that is meshed with screw mandrel 12 perpendicular to the handle of a knife axis and in the handle of a knife centre, this screw mandrel one end is fixing by manually revolving 22, the other end is positioned on the axle bed 24 with stop screw 23 locking, and the butterfly spring 25 of an elimination thread pitch is respectively arranged on this screw mandrel between in handle of a knife and the jacking block leading section chamber.

The utility model principle of work is: this device is rectangular bar shaped, shape such as lathe tool, therefore can equally with other lathe tool be fixed on the tool holder, that adjusts jacking block manually revolves an X who is used to finely tune gauge head to value, and the head that manually revolves of adjusting handle of a knife is used to finely tune the Z of gauge head to value.This device is as the benchmark cutter, in case after tool setting is finished in the machine, only get final product with this device contrast for the wearing and tearing of other lathe tool on the frame, when changing workpiece, the X of fine setting gauge head to be worth, Z gets final product to being worth.
