The specific embodiment
Embodiment:
Present embodiment is a kind of CNC roll grinder measuring mechanism, as shown in Figure 1, 2.Present embodiment comprises: driving by horizontal movement device can be at the base 9 of horizontal guide rail 12 slips, described base is provided with by whirligig 16 and drives rotatable vertical axes 17, described vertical axes is provided with gage beam panel 18, described gage beam panel is provided with upright guide rail 19, described upright guide rail is provided with the upper and lower gage beam 4,8 that can move up and down along upright guide rail, be provided with the displacement transducer 1 that detects upper and lower gage beam displacement along described measurement guide rail, described horizontal guide rail is arranged on the lathe bed 10 of CNC roll grinder; Described measurement panel is provided with the linear motor stator electric 2 of strip, and the mover of described linear electric motors is arranged on described upper gage beam or the lower gage beam; The upper and lower of described measurement panel is respectively equipped with a sprocket wheel 3,7, and with a chain 6, described chain is fixedly connected with upper gage beam, lower gage beam respectively in the sprocket wheel both sides on the described sprocket wheel.
The operation principle of the described mechanism of present embodiment: as shown in Figure 1, horizontal guide rail is arranged on a side of tested roll 5, extends axially along roll, and is parallel with the roll gyroaxis.Measuring mechanism is in respectively radially relative position, both sides of roll with emery wheel 20, and both do not interfere with each other, but the limit broken is measured.
Described horizontal guide rail is designed to two V rail structures, makes gage beam obtain higher operation and positioning accuracy.This is that the measuring mechanism of conventional mounting on the large balladeur train of emery wheel is incomparable.Because weight and the cutting force of guide rail in order to bear emery wheel of large balladeur train, guide rail is stressed larger, so can not be designed to two V structures, can only be designed to a V-type rail, a level gauge.And the weight that the described horizontal guide rail of present embodiment only bears measuring mechanism itself, guide rail is stressed less, so can adopt double V-shaped guide rail.Because the guide rail of measuring mechanism separates with the guide rail of large balladeur train, so can propose specification requirement to the guide rail of measuring mechanism and the guide rail of large balladeur train respectively in the process of Design and manufacture roll grinder: the specification requirement of large carriage rail is relative low, and measuring mechanism is owing to needing higher certainty of measurement, so can propose higher specification requirement to the guide rail of measuring mechanism.Seeming like this guide rail that has increased measuring mechanism has seemingly increased the cost of roll grinder, and actual (guide rail of large balladeur train is larger owing to can reduce the accuracy of manufacture of large balladeur train in manufacture process, improve relatively difficulty of the accuracy of manufacture, and the guide rail of measuring mechanism is less, it is relatively easy to improve the accuracy of manufacture), holistic cost also might reduce.Therefore, the design that the guide rail of the guide rail of measuring mechanism and large balladeur train is separated all has advantage aspect the certainty of measurement two manufacturing and designing and improve.
Described horizontal movement device can be the rack-and-pinion transmission, namely at guide pass tooth bar 13 is installed, and the motor 14 of stationary drive gear and gear 15 on the base make the motor-driven base move along horizontal guide rail.Described motor can keep certain operational relation by controller and grinding wheel drive mitor, makes the operation of base synchronous with the operation maintenance of the large balladeur train that emery wheel is installed, and realizes the real-time tracking monitoring that the limit broken is measured.
For abdicating the space of roll loading and unloading, measure erecting of panel on the rotating seat with rolling bearing 11, measure panel and gage beam mounted thereto and can do 90 degree and rotate, when roll when roll grinder is installed or dismantles, gage beam forwards on one side, avoids colliding with gage beam and roll.The power of rotation can be motor, hydraulic motor, air motor, drives by gear drive and measures the panel rotation, also can drive with oil cylinder or cylinder and measure the panel rotation.
The both sides of measuring panel all are equipped with upright guide rail 1901,1902, are respectively the kinematic constraint of upper and lower gage beam, and described upper and lower gage beam lays respectively at measures the panel both sides, as shown in Figure 2.Described upright guide rail can be that rail plate also can be rolling guide.
Described up and down two sprocket wheels are installed between the face of measuring the panel both sides, namely the axle of two sprocket wheels is installed in the position of the symmetry axis of measuring the panel two sides, sprocket wheel exposes respectively one section circular arc two sides, and chain is walked between two faces measuring panel.Because the operation of chain between two sprocket wheels is opposite motion, so when the chain of sprocket wheel both sides is fixedly connected with upper and lower gage beam respectively, two gage beams that both sides side chain bar drives respectively are move toward one another, for example going up gage beam moves downward, then descend gage beam to move upward, otherwise upper gage beam moves upward, then descend gage beam to move downward, the action that the upper and lower gage beam of whole formation is embraced and separated, be similar to the action of kind of calliper leg, measure the external diameter of roll when embracing, withdraw from measurement in the time of separately.Utilize the move toward one another of sprocket wheel both sides chain to produce embracing of measurement and separate greatly simplified measurement mechanism.Compare with the transmission mode of traditional positive left-hand thread leading screw, the employed chain transmission mode of present embodiment is not only simple in structure, and certainty of measurement is further enhanced.
The power that gage beam moves up and down comes from linear electric motors.Measuring panel and arrange the stator coil of linear electric motors, the mover of linear electric motors can be arranged on the gage beam, also can be arranged on the lower gage beam.Because two gage beams are by the chain interlock, so namely can drive two gage beams motions on the gage beam as long as the mover of linear electric motors is arranged on.Owing to adopt the relative motion of two gage beams of chain drive, so can use linear electric motors.Adopt the displacement that linear electric motors can high-precision controlling run, with respect to traditional rotary-type stepper motor, its displacement is more prone to control, and precision is higher, and this point is advantageous particularly for the external diameter high-acruracy survey of rotary work piece.
For the accurate displacement that detects gage beam, on the measurement panel, also be provided with displacement transducer, described displacement transducer can be the sensor of various accurate detection displacements, such as grating scale, magnetic railings ruler or to hold the precision such as grid chi higher and the physical signalling of displacement can be converted to the displacement transducer of the analog or digital signal of telecommunication.
For safety, can be at upper limit of movement and the motion lower limit mounting limit device of gage beam, described stopping means can be simple limited block, also can be limit switch.Be to trigger limit switch when gage beam reaches largest motion restriction, cut off the power supply of linear electric motors, gage beam is no longer moved.
It should be noted that at last, below only unrestricted in order to the technical solution of the utility model to be described, although with reference to the preferred arrangement scheme the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model (such as the form of measuring panel, the position of displacement sensing line, the installation site of sprocket wheel etc.), and not break away from the spirit and scope of technical solutions of the utility model.
