Description

A kind of wheel life testing machine

Technical field

The present invention relates to mechanical test equipment, be used in particular for testing the test machine in wheel life-span.

Background technology

Generally can only lean on range estimation to the quality testing of wheel in the market, and range estimation there is the rub proofness that can not find out material.Manufacturer otherwise use by the user after feedback learn the quality of wheel, or just go to buy somewhat expensive equipment special detection, can raise the cost greatly like this.

Summary of the invention

Purpose of the present invention is to solve the problems of the technologies described above, and provides a kind of simple in structure, easy to use, can be efficiently, the test machine in fast detecting wheel life-span.

Technical solution of the present invention is: a kind of wheel life testing machine comprises support and base, the counter that described base is provided with rotating disk free to rotate, is used for fixing the stationary installation of tested wheel and is used for record rotating disk distance travelled; Described rotating disk is connected with drive unit, described stationary installation centered by rotating disk, be evenly distributed on rotating disk around.

The wheel surface that the device that is fixed is fixing and rotating disk are fitted, and drive dial rotation by drive unit, drive wheel turns by rotating disk, and counter can record the stroke of rotating disk, so just can know the serviceable life of wheel by the wear condition of wheel.Whole tester architecture is simple, and is easy to operate, and can test together by a plurality of wheels, improved testing efficiency.

As preferably, described stationary installation comprises cylinder, bearing seat and guide shaft, and guide shaft passes the outer end of bearing seat fixed part is set.Fixed part is used for the fixedly position of wheel, is connected with wheel turns.

As preferably, described each stationary installation is connected in parallel by aerostatic press, and air pressure is stablized in unified output.In order better to test the life situations of wheel under certain pressure, so give pressure stable of guide shaft to cylinder, the wheel of being fixed by guide shaft can receive that also same acting force contacts with rotating disk like this.Guarantee that the pressure that each wheel is received is consistent, improve the precision that detects.

As further preferred, described guide shaft is provided with block, is provided with the axial groove and the radial strut groove that cooperate with block in the described bearing seat.Guide shaft can stretch in bearing seat under the situation of not receiving acting force, be conducive to the installation or removal wheel like this, if but do not have radially bed knife, guide shaft can rotation in bearing seat, be unfavorable for testing wheel like this, so we are provided with axial groove and radial strut groove in bearing seat.The block that is connected with guide shaft makes the guide shaft can rotation under axial groove spacing.When we want installation or removal, block can be moved to the position of radial strut groove, guide shaft just can rotate like this.

As further preferred, an end of described axial groove arranges baffle plate, is used for preventing that guide shaft from passing outside the bearing seat.

As preferably, described stationary installation is four.In order to add high-level efficiency, can detect simultaneously by a plurality of wheels.

As preferably, be connected with display screen on the described counter.For more convenient user's record and operational testing machine, thus at speed counter display screen is installed, can better observation test process and record case.

As further preferred, described counter is connected by electric wire with drive unit, and described display screen is provided with the gauge tap of accessory drive.When counter shows that rotating disk has forwarded certain stroke to, just can stop by accessory drive like this.The user can be more accurately purposeful detection wheel also.

As preferably, also comprise the protective cover that is arranged on the base.Hurt operator or other mishaies in order to prevent that wheel from flying out, so be provided with a protective cover, the equipment of the inside is covered, but this protective cover generally all is transparent material, can make things convenient for the user to observe.

Beneficial effect of the present invention is: a plurality of detected wheels move under the drive of a rotating disk, and cylinder gives wheel a constant compression force.Rotation mileage and the travelling speed of rotating disk, the pressure that cylinder gives can accurately be controlled, and tested wheel can be changed fast.It is low, easy to operate that this test machine has a cost, detection efficiency height, precision advantages of higher.

Embodiment

The invention will be further described with embodiment below in conjunction with accompanying drawing.

Embodiment 1, as depicted in figs. 1 and 2, and fixedly connected circle or square base 2 on four jiaos the support 1, in the base 2 circular port is arranged, be provided with circular rotating disk 3 on the hole, the rotating disk 3 general magnet steel materials that adopt, rotating disk 3 one sides have the rotation mileage of 5 pairs of rotating disks of counter to carry out record.Useful Hall element is gathered signal in the counter 5.Rotating disk has connected drive unit 73 times, and drive unit 7 comprises equipment such as motor, rotating shaft, frequency converter and reductor.The rotational speed of wheel is set by converter parameter.Fixedly connected at least more than one stationary installation 4 on the base 2, described stationary installation 4 is used for the position of fixing tested wheel.Described stationary installation 4 comprises cylinder 41, bearing seat 42 and guide shaft 43, and guide shaft 43 passes bearing seat 42 outer ends fixed part 431 is set, and fixed part 431 is U-shaped clamping plate, and tested wheel is arranged at the centre of lower plate, by bolt therein.The surface level that will guarantee tested wheel simultaneously is parallel with the surface level of rotating disk 3.Each cylinder 41 is connected in parallel by aerostatic press 10, and air pressure is stablized in unified output.Can guarantee the pressure unanimity that each wheel is subjected to like this.Guide shaft 43 is to be socketed in the bearing seat 42, and one is welded with block 45 on the described guide shaft 43, is provided with the axial groove 44 and the radial strut groove 46 that match with block 45 in the bearing seat 42.The one end welding baffle plate 47 of described axial groove 44 is used for preventing that guide shaft 43 from passing outside the bearing seat 42.Do not having under the situation of air pressure, the block 45 of guide shaft 43 can be done axially-movable in axial groove 44, because the position-limiting action of axial groove 44 is arranged, guide shaft 43 can rotation.Only when the installation or removal wheel, the block 45 of guide shaft 43 can be dragged to the position of radial strut groove 46, guide shaft 43 just can rotate like this, has to be convenient to dismantle for the fixing bolt of wheel.Counter 5 just is connected by electric wire with motor with drive unit 7, and display screen 6 is housed on the counter 5, and described display screen 6 is provided with the gauge tap 8 of control motor.Counter can be set and estimate the test revolution, wait arrive target after, just stop motor automatically, test stops automatically.For work safety, at base 2 protective cover 9 of a transparent material is set, so both can the observation test process, the generation probability that can reduce security incident is arranged.
