Description
Technical field
The invention belongs to technical field of measurement and test, and in particular to contact wheel is to processing stall monitoring and wheel footpath self-operated measuring unit.
Background technology
At present, with the high speed development of railway construction, rolling stock constantly raises speed and distance travelled number is continuously increased so that wheel is repaiied workload and greatly increased to Xuan, to taking turns the machining accuracy after being repaiied to profile Xuan proposes requirement higher.
Correspondingly, railway vehicle wheel repaiies process technology to Xuan also developing rapidly, but most of wheel repaiies equipment to Xuan all using friction-driven at this stage, i.e., by friction pulley with wheel to the directly contact driving wheel on surface to rotation, there is provided required chip power.Because the size of chip power is influenceed by scrap rate and wheel on material etc., if scrap rate or feed rate selection are improper, when driving wheel frictional force is less than required cutting force, driving wheel will be made and slide relative to contact surface appearance is taken turns, take turns and occur to stall event, cause wheel to damage scorch and lathe, influence machining accuracy.When wheel is to there is pronounced stall, it is also possible to collapse knife phenomenon, major injury is caused to surface to taking turns, during rolling friction is changed into sliding friction, driving wheel rapid wear will be caused, greatly shorten its service life.
Wheel is to after Xuan is repaiied again, must be to taking turns to carrying out diameter measurement, the way of usual manual measurement is that wheel footpath measuring scale is lain in into wheel to diameter measurement position, observe by the naked eye to determine wheel to diameter, this measuring method disadvantage is low efficiency, labour intensity is big, and certainty of measurement receives artificial affecting, it is difficult to meet the railway demand of high speed development.
The content of the invention
Low two problems of manual measurement wheel footpath efficiency after equipment easily produces wheel that serious consequence and wheel are caused to stall to being repaiied in Xuan again using friction-driven are repaiied to Xuan for wheel, the invention provides contact wheel to processing stall monitoring and wheel footpath self-operated measuring unit, including base, transmission case, oil cylinder, swing arm, measurement wheel and rotary encoder, in transmission case mounting seat, oil cylinder is fixed on transmission case, swing arm is connected by with the power transmission shaft in transmission case, can swing back and forth, measurement wheel is arranged on the termination of swing arm by bearing, can be rotated freely around bearing centre, and can be with wheel to rotating, rotary encoder is arranged on the termination of swing arm, turn-taked number for recording measurement wheel.Base provides support for package unit, rises and installs fixation.Oil cylinder provides pressure for swing arm rotation and measurement wheel are contacted with wheel to surface, and transmission case is movement transforming device, i.e., the linear motion of oil cylinder is output as the rotary motion of swing arm by power transmission shaft.
Further, rotary encoder be incremental encoder or absolute value encoder, or other can realize multi-turn measure encoder.
The present invention obtain beneficial effect be：Real-time stall monitoring is provided in process, is that operator takes appropriate measures there is provided foundation, it is to avoid cause damage of the wheel to finished surface and lathe in process due to stall, improve machining accuracy.Wheel then improves certainty of measurement and production efficiency to wheel footpath automatic measurement, reduces the labour intensity of workman.

Specific embodiment
The present invention is further explained with reference to Figure of description.
Referring to Fig. 1 and Fig. 2, contact wheel is to processing stall monitoring and wheel footpath self-operated measuring unit, constituted including base 1, transmission case 2, oil cylinder 3, swing arm 4, measurement wheel 5 and rotary encoder 6, in the mounting seat 1 of transmission case 2, oil cylinder 3 is fixed on transmission case 2, swing arm 4 is connected by with the power transmission shaft in transmission case 2, can swing back and forth, measurement wheel 5 is arranged on the termination of swing arm 4 by bearing, can be rotated freely around bearing centre, and can be rotated to 7 with wheel, rotary encoder 6 is arranged on the termination of swing arm 4, is turn-taked number for recording measurement wheel 5.Base 1 provides support for package unit, rises and installs fixation.Oil cylinder 3 is rotated and measurement wheel 5 contact to 7 surfaces and provide pressure with wheel for swing arm 4, and transmission case 2 is movement transforming device, i.e., the linear motion of oil cylinder 3 is output as the rotary motion of swing arm 4 by power transmission shaft.
Further, rotary encoder 6 be incremental encoder or absolute value encoder, or other can realize multi-turn measure encoder.
In wheel repaiies process to 7 Xuan, jig carries out positioning and clamping to 7 by 10 pairs of wheels of axle box, and driving wheel 8 is contacted with wheel to 7 surfaces, and moment of torsion and pressure on driving wheel 8 are applied to by driver element, and friction driving roller is to the chip power needed for 7 offer cutters 9.
In the case of not stall, both peripheral speeds of measurement wheel 5 and driving wheel 8 are equal.When the chip power needed for the friction drive between driving wheel 8 and wheel are to 7 is not enough to provide; the slip relative to generations between 7 with wheel of driving wheel 8 will be caused; at this moment the wheel that rotary encoder 6 is measured will be less than peripheral speed of the default to driving wheel 8 to 7 actual peripheral speed; both data are contrasted; if exceeding error range; the system information alert operator that will give a warning takes appropriate measures, and such as reduces feed rate or system automatic emergency is shut down.
Because measurement wheel 5 to 7 mantle frictions with wheel due to often contacting, it is therefore necessary to improve the wearability on surface by special heat treatment, to meet certainty of measurement requirement.The shaft end of rotary encoder 6 is then directly connected to measurement wheel 5, for recording the parameter such as 5 angular velocity of rotations of measurement wheel and the number of turns in whole measurement process.
For taking turns to 7 wheel footpath automatic measurements, wheel rotates to 7 under the driving of driving wheel 8, measurement wheel 5 is connected with wheel to 7 surfaces, show that measurement wheel 5 is turn-taked several n1 by rotary encoder 6, known measurement wheel Zhou Changwei L, if wheel is turn-taked to 7, number is that n2 then can calculate wheel to diameter D by formula D=n1L/ π n2, wheel footpath data are directly read by digital control system, wheel footpath automatic measurement is realized.
The above is the preferred embodiments of the present invention, it is not intended to limit the invention, for the technology of this area, it is made up of base 1, transmission case 2, oil cylinder 3, swing arm 4, measurement wheel 5 and rotary encoder 6, various modifications and variations have been allowed as the structure of stall monitoring and wheel footpath self-operated measuring unit using contact mode, every any modification within the spirit and principles in the present invention, made, equivalent, improvement etc. are all contained in the scope of the invention.
