Abstract
The invention discloses a method for accurately calibrating the inclination of a vertical milling head of a milling machine by using a dialgauge. In the method, after the vertical milling head deviates an angle according to an inclined plane or inclined hole of a workpiece to be machined, the dialgauge is fixed on a workbench, a horizontal distance and a vertical distance between two points on the outer wall of a part, which is arranged on the vertical milling head and coaxially extends with the vertical milling head, and has an outer surface parallel to the axis of the vertical milling head, are measured by the dialgauge, the data obtained through measurement is calculated, the deviation between the actual deflection angle and the set deflection angle of the vertical milling head is compared, and the vertical milling head is regulated to a right place according to the deviation. By the method, the inclination of the vertical milling head of the milling machine can be accurately calibrated, the production period of the product is shortened, the production cost is reduced, and the method has high promotion and application value.
Description
Technical field
The present invention relates to a kind of method of utilizing dial gauge accurate correction milling machine end mill head inclination angle.
Background technology
When processing precise inclined-plane or inclined hole, generally need to use special fixture on milling machine, because the manufacturing cost of special fixture is higher, comparatively trouble is installed, therefore this method is applied to large batch of production usually.When the trial-production of single-piece or small lot is produced, use special fixture can improve the processing cost of workpiece, and make fixture and also need the special-purpose time, cause the process-cycle to extend, incur loss through delay production trial-production task.
Summary of the invention
Task of the present invention is: a kind of method of utilizing dial gauge accurate correction milling machine end mill head inclination angle when single-piece or small lot batch manufacture is provided, to shorten the process-cycle, cuts down finished cost.
Technical scheme of the present invention is: a kind of method of utilizing dial gauge accurate correction milling machine end mill head inclination angle, it is characterized in that, and this method comprises the following steps:
1., the angle of setting the deflection of end mill head needs according to the requirement of workpiece to be processed is α;
Angle [alpha] of angle [alpha] deflection of 2., the end mill head correspondence being set ';
3., dial gauge is fixed on the workbench of milling machine, and the feed mechanism that shakes milling machine is pressed on the outer wall of end mill head the contact top of dial gauge, this contact point is as starting point;
4., eliminating the horizontal cross feed mechanism that shakes milling machine after leading screw in milling machine horizontal cross feed mechanism and the play between screw makes dial gauge to moving away from the end mill head direction, shaking contact that vertical feed mechanism makes dial gauge contacts with another point on end mill head again, this contact point is terminal point, line between terminal point and starting point and the axis parallel of end mill head record the amount of moving horizontally of dial gauge and vertical amount of movement simultaneously;
5., according to the amount of moving horizontally of the dial gauge that records and vertically amount of movement calculate the actual deflection angle [alpha] ' numerical value and obtain actual deflection angle [alpha] ' of end mill head and the departure between set angle α with the trigonometric function formula;

Description of drawings
Fig. 1 is principle schematic of the present invention.
The specific embodiment
The present invention utilizes dial gauge to come accurate correction milling machine end mill head inclination angle.The present embodiment take the processing precise inclined-plane or inclined hole as example.At first carry out previous preparatory work, the angle of the inclined-plane of the workpiece of processing or inclined hole setting end mill head 3 deflections is α as required, then with the corresponding angle [alpha] deflection of setting of milling machine end mill head 3, the actual angle of deflection is made as α ', dial gauge 4 is fixed on the workbench 2 of milling machine by magnetic stand 5 again, and the contact top press contacts that the feed mechanism that shakes milling machine table 2 makes dial gauge 4 is on the outer wall of end mill head 3, with this point as starting point A.after preparation is completed, the horizontal cross feed mechanism 1 that shakes workbench 2 makes dial gauge 4 move the terminal point B that moves horizontally that arrives dial gauge 4 towards the direction away from end mill head 3, the vertical feed mechanism 6 of shaking again workbench 2 vertically moves up dial gauge 4, until the contact top press contacts of dial gauge 4 is on another aspect of the outer wall of end mill head 3, this point is recorded as vertical mobile terminal point C, line AC between this vertical mobile terminal point C and starting point A needs the axis parallel with end mill head 3, then change according to the scale of horizontal cross feed mechanism 1 on workbench 2 and vertical feed mechanism 6 and amount of movement that the reading of dial gauge 4 calculated and recorded the horizontal direction of dial gauge 4 is that the amount of movement of displacement between 2 of AB and vertical direction is the displacement between 2 of BC, after the distance of 2 of the distance of learning 2 of AB and BC, according to trigonometric function formula tan α '=AB/BC can calculate end mill head the actual deflection angle [alpha] ' numerical value, with this actual deflection angle [alpha] ' compare with the numerical value of setting deflection angle α, calculate the actual deflection angle [alpha] ' with setting deflection angle α between departure, last departure according to obtaining is adjusted the deflection angle α ' of end mill head 3.After completing, adjustment re-starts above-mentioned steps, until the actual deflection angle [alpha] of end mill head 3 ' and set between deflection angle α zero deflection or departure within the scope that technique allows.
After wherein it should be noted that the leading screw and the play between screw in moving horizontally the front needs of workbench 2 and first eliminate the horizontal cross feed mechanism 1 of workbench 2, the eliminating direction of play is opposite with the moving direction of dial gauge 4.
Proofread and correct end mill head actual deflection angle [alpha] ' the time, can also use trigonometric function formula tan α=AB/BC to calculate end mill head 3 at the theoretical amount of movement of vertical direction, be the theoretical numerical value between 2 of BC, the actual numerical value of the actual BC point-to-point transmission that obtains is compared with the theoretical numerical value that calculates, calculate its departure, then readjust the deflection angle α ' of end mill head 3 according to departure.
At the timing that carries out above-mentioned end mill head deflection angle, the distance that moves horizontally of workbench 2 is larger, the actual deflection angle [alpha] of the end mill head of measuring ' precision higher, correction more accurate.
When single-piece or small lot trial-production production, adopt method processing precise inclined-plane or the inclined hole that utilizes dial gauge accurate correction milling machine end mill head inclination angle of the present invention, do not need special fixture, can shorten the production cycle, lower production cost, have application value more widely.In addition, when the present invention can also be applied in milling machine processing precise elliptical aperture, to the accurate correction at end mill head inclination angle.
