The utility model relates to a kind of measurement mechanism of the car wheel lathe that do not fall, and especially for meeting numerical control, does not fall car wheel lathe to train wheel testing requirement.
Background technology
In prior art, numerical control is not fallen to car wheel lathe in process, in order to detect the precision of wheel, need to probe be installed in knife bar side, directly use probe measurement.Although this mode is simple in structure, because the structure of probe is doomed to wear and tear, therefore there is low precision when measuring wheel rim, a little less than antijamming capability, flimsy defect and deficiency.
Summary of the invention
The purpose of this utility model is to measure actual operation requirements for deficiency of the prior art and locomotive, provides a kind of and can meet various processing environments, and the checkout gear of the profile that can Measurement accuracy do not fall.
The technical solution adopted in the utility model is: in the installing of knife rest side, be equipped with a measuring box, be provided with the measurement mechanisms such as diameter measurement wheel, interior range finding meter wheel, probe and rotary encoder in measuring box; The leading screw arranging in measuring box matches with servomotor, and said measurement mechanism can longitudinally stretch out measuring box under the control of servomotor, also can under the control of horizontal servomotor, with knife rest, realize transverse shifting; Diameter measurement wheel in measurement mechanism, interior range finding meter wheel touch while needing to detect the wheel rim of wheel, and the mechanism by being connected with diameter measurement wheel, interior range finding meter wheel, is transmitted to probe by signal.The servomotor by horizontal and vertical movement moves, and realizes and detects the interior range finding of wheel and flange height, flange thickness, the tip diameter of tread.
The said car wheel lathe checkout gear that do not fall of the utility model, its formation comprises:
A) servomotor and the leading screw that measurement mechanism is moved both vertically;
B) be a set ofly connected with meter wheel, be used for the rotary encoder of meter wheel to diameter;
C) two meter wheels that are connected with probe, i.e. diameter measurement wheel and interior range finding meter wheel.
Through check, adopt the said car wheel lathe checkout gear that do not fall of the utility model, Stability Analysis of Structures, accuracy of detection is high, and antijamming capability is strong, can not meet the requirement that car wheel lathe detects.

The specific embodiment
Below in conjunction with accompanying drawing, to the car wheel lathe checkout gear that do not fall described in the utility model, utilize and do not fall car wheel lathe to the structure of train wheel checkout gear and principle, be further described and illustrate.
Fig. 1 is the measuring box internal structure schematic diagram of the said car wheel lathe checkout gear that do not fall of the utility model, and its constituent relation comprises:
Fig. 2 is the said car wheel lathe checkout gear transmission diagram that do not fall of the utility model.Wherein measuring box 10 is arranged on knife rest 7 sides, knife rest 7 is placed in to fall on the pedestal 13 of car wheel lathe, by servo longitudinal motor 12, driven and realized vertically moving of knife rest 7, the transverse shifting of knife rest 7 and measuring box 10, drives transverse shifting leading screw 14 to realize by horizontal servomotor 11.
The said car wheel lathe checkout gear that do not fall of the utility model, its formation comprises:
A) servomotor 6 and the leading screw 4 that measurement mechanism is moved both vertically;
B) be used for the rotary encoder 3 of meter wheel to diameter;
C) the diameter measurement wheel 1 and the interior range finding meter wheel 2 that are connected with probe 5.The rotating shaft of diameter measurement wheel 1 is axially vertical with axletree, is used for the axial runout of the right axial location of meter wheel and wheel rim; The rotating shaft of interior range finding meter wheel 2 and axletree axially parallel, be used for the abrasion of the right diameter of meter wheel and profile.
The said car wheel lathe checkout gear that do not fall of the utility model, its operation principle is as follows:
1) distance between backs of wheel flanges is measured
The interior range finding meter wheel 2 of machine adopted diameter phi 50mm in this example comes the right axial location of meter wheel, inner side distance and axial runout.
2) wheel diameter is measured
Wheel is by carbide alloy roller to the measurement of diameter, and its diameter is surperficial realization of rolling circle that the diameter measurement wheel 1 of φ 90mm is pressed in wheel.When taking turns rotation, the anglec of rotation that is connected in the rotary encoder 3 statistical measurement wheels on diameter measurement wheel 1, rotary encoder 3 is connected with digital control system, and this numerical signal is transferred to digital control system, by digital control system, this numerical value is processed, can be calculated the right diameter parameters of wheel.
3) profile measurement of wear
Wheel is by a carbide alloy roller (being φ 90mm diameter measurement wheel 1) is measured X-axis value and the data that obtain are processed to realize in Z plane 9 to the measurement of wear of profile.The X value recording (corresponding to each Z axis position) is sent to digital control system, and digital control system is processed and is provided the abrasion of wheel to profile it.
