Abstract
The utility model belongs to the technical field of machines, and particularly relates to a mobile measuring frame for parts of grinding shafts of a grinding machine. The mobile measuring frame is characterized in that a set of mobile mechanisms driven by a servo motor is additionally arranged in front of a front grinding machine body of the grinding machine so as to drive the measuring frame to move and realize on-line measurement of each gear size in the grinding process. The mobile mechanism consists of a servo motor, a speed reducer, a coupling and a ball screw which are connected in sequence; and the ball screw is connected with the bottom of a measuring platform. The mobile measuring frame overcomes the defects of grinding at fixed distance, so that each gear of grinding shaft neck can be measured in an online manner, and the high-accuracy requirement to the size is guaranteed.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to the traverse measurement frame that a kind of grinding machine axial workpiece is used.
Technical background
Along with the development of present technology, also more and more higher to the dimension precision requirement of grinding machine axial workpiece, traditional method is many grades of outer bowlders of grinding, adopts the measurement size tolerance to measure than higher one grade, and other size files adopts the method for deciding the journey grinding.Its shortcoming is other shelves of deciding the journey grinding adopting, owing to the reasons such as error of lathe, causes dimensional accuracy to descend.In addition on the composite grinding grinding machine, often dispose two cylindrical emery wheel bistriques on the grinding carriage,, realize the different axle journal measurements of each grade if adopt manual adjustments measurement bay Z-direction, both be unfavorable for the realization of automatic grinding, also may be because frequent the adjustment reduced dimensional accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of guarantee grinding dimensional accuracy, the grinding machine axial workpiece traverse measurement frame that also can carry out on-line measurement.
The traverse measurement frame of the utility model design is exactly lathe bed front before grinding machine, increases the travel mechanism that a cover is driven by servomotor, drives moving of measurement bay, is implemented in the grinding process on-line measurement to every grade of size.
The travel mechanism of described traverse measurement frame is by servomotor 5, reductor 6, and shaft coupling 7, bearing 8, ball screw 9 is formed; Wherein, servomotor 5 is connected with reductor 6, and reductor 6 is connected with an end of ball screw 9 by shaft coupling 7; The two ends of ball screw 9 are by bearing 8 fixed bits; Ball screw 9 is connected with the bottom of test desk 11 by nut seat 10.
In the utility model, servomotor directly is connected with shaft coupling with ball screw, and can select reductor on demand for use, with suitable reduction rotating speed, increase moment of torsion.
When grinding work piece, by the coordinate of servo-drive system control survey frame in Z-direction, when workpiece adds man-hour in journal size size variation and composite grinding, the measuring position changes in Z-direction, adjust the coordinate of measurement bay on Z-direction this moment, can realize on-line measurement.
The utility model adopts the form of traverse measurement frame, has overcome the shortcoming of deciding the journey grinding, makes every grade of grinding axle journal can on-line measurement, has guaranteed the high-precision requirement of size.
Description of drawings
Fig. 1 structure of the present utility model is always schemed.
Fig. 2 traverse measurement frame front view.
Fig. 3 traverse measurement frame side view.
Number in the figure: 1 is lathe bed before the grinding machine, and 2 is lathe bed behind the grinding machine, and 3 is grinding carriage, 4 is measurement bay travel mechanism, and 5 is servomotor, and 6 is reductor, 7 is shaft coupling, and 8 is bearing, and 9 is ball screw, 10 is nut seat, and 11 is test desk, and 12 is line slideway, 13 is hydraulic jack, 14 is the standard oil cylinder, and 15 is measuring staff, and 16 is the measuring instrument support.
The specific embodiment
As shown in Figure 1, measurement bay travel mechanism 4 is installed in lathe bed 1 front before the grinding machine, and grinding carriage 3 is installed in behind the grinding machine on the lathe bed 2.When the wheel grinding position changed: measuring position A → measuring position B, the test desk in the measurement bay travel mechanism 4 moved from A → B under the drive of servomotor, thereby realizes the on-line measurement of diverse location.
Fig. 2 is the moving structure figure of test desk, and test desk 11 is connected with nut seat 10, and test desk drives the lower edge Z-direction at ball screw 9 and moves.Servomotor 5 is connected with ball screw 9 with shaft coupling 7 through reductor 6.The accurate location that servo-drive system realizes test desk by control servomotor 5.
Fig. 3 test desk 11 is connected with preceding lathe bed 1, and by moving under the drive of ball screw 9, the turnover of measuring staff 15 drives by the two-stage of hydraulic jack 13 and standard oil cylinder 14 test desk on line slideway 12, realizes moving of X-direction.The vary in diameter of measuring workpieces can be regulated by the measuring staff on the regulated quantity instrument support 16 15.
Claims (2)
1. the traverse measurement frame that the grinding machine axial workpiece is used is characterized in that it being lathe bed front before grinding machine, increases the travel mechanism that a cover is driven by servomotor, drives moving of measurement bay, is implemented in the grinding process on-line measurement to every grade of size.
2. traverse measurement frame according to claim 1 is characterized in that described travel mechanism is made up of servomotor (5), reductor (6), shaft coupling (7), bearing (8), ball screw (9); Wherein, servomotor (5) is connected with reductor (6), and reductor (6) is connected with an end of ball screw (9) by shaft coupling (7); The two ends of ball screw (9) are by bearing (8) fixed bit; Ball screw (9) is connected with the bottom of test desk (11) by nut seat (10).
