The mower testing equipment provided with fastening devices can be adjusted to fix a mower to be tested according to a size of the mower to be tested, the mower will not vibrate in large amplitude and rotate in testing process, noises are reduced, falling of parts of the mower to be tested is prevented, simultaneously test loading is more accurate, and test standards are complied.
Description
Technical field
The utility model belongs to the testing apparatus field, particularly a kind of mower testing apparatus with fastener.
Background technology
Requirement according to international standard IEC/EN60335-2-77 Cl.11, need to test the temperature rise that mower carries out under the normal operating conditions, standard IEC/EN60335-2-77 Cl.3.1.9 regulation normal operating conditions is the logical rated voltage of mower, loads simultaneously to reach rated power.According to above standard-required, for the normal temperature rise test of mower, it is vertical dynamometer machine that a vertical loading test device need to be arranged.Traditional vertical loading device directly is placed on mower on the charger, by the loading to the mower bottom, the described loading requirement of realization standard.Because mower is in loading the course of work, the power that axially loads can make mower produce vibrations and rotation, rotation and vibrations make again the power of mower vertical loading produce decomposition, mower can not constantly be operated under the rated power, and not satisfy the standard testing requirement.Therefore traditional vertical loading proving installation that does not have fastener can affect test condition and cause certain noise and potential mechanical wounding danger.
Existing testing apparatus mainly by experiment support platform and damping motor, is placed on mower on the support platform during test, and the damping motor is tested the weeder vertical loading.The defective that exists is: can not carry out tested mower fasteningly in (1) test process, easily produce noise.(2) parts of sample (such as wheel, protective cover etc.) are if unreliable fixing, and the vibrations in the test process easily make these parts generations come off or splash, and cause mechanical wounding.(3) axially the power of loading can make the mower generation shake and rotation, makes the power of mower vertical loading produce decomposition, and the tested mowing function of very difficult assurance is worked under constant power.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and reliable loading standard compliant mower testing apparatus with fastener.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of mower testing apparatus with fastener, comprise test support platform and damping motor, be provided with two pairs of mower tire fasteners on the described test support platform with going back Parallel Symmetric.Fixing two pairs of tires in front and back of mower.
Described mower tire fastener comprises the lateral adjustments slide rail that is arranged on the test support platform, described lateral adjustments slide rail is provided with the laterally lateral adjustments fixed block of slidable adjustment, described lateral adjustments fixed block is provided with vertical adjusting fixed block of can longitudinal sliding motion regulating, described vertical adjusting fixed block is provided with tyre side position fixed block, the two ends of described tyre side position fixed block are provided with and are oppositely arranged locating piece behind wheel prelocalization piece and the wheel, one end of described tyre side position fixed block also is provided with the tire hold-down mechanism, described tire hold-down mechanism comprises that the hold-down mechanism that is arranged on tyre side position fixed block one end props up weighing lever, be arranged on hold-down mechanism and prop up hold-down mechanism bearing on the weighing lever, handle, the limit pre-pressing piece, clamping screw supports, described hold-down mechanism bearing, handle, use between limit pre-pressing piece and clamping screw support and adopt chain connection, consist of the chain connection four-bar mechanism, described clamping screw supports and is provided with clamping screw.Tyre side position fixed block can vertically be regulated according to the wheelspan of mower, to fix the side of a pair of tyres on the axle, locating piece can prevent the tire scroll forward and backward of mower behind wheel prelocalization piece and the wheel, the lateral adjustments fixed block can be according to the wheelbase lateral adjustments of mower simultaneously, and described tire hold-down mechanism can prevent mower bob in test process.
Described tyre side position fixed block is provided with rear locating piece and regulates chute, and locating piece can be arranged on to slidable adjustment on the fixed block of tyre side position behind the described wheel.To adapt to different wheel footpaths.
Locating piece is triangle behind described wheel prelocalization piece and the wheel.The contact area of increase and tire is fixing more effective.
Described lateral adjustments slide rail is 12, and per three is one group, is arranged on the described test support platform Parallel Symmetric.When the change in size of tested mower when vertically regulating the stroke range of fixed block, the two pairs of lateral adjustments slide rails of can selecting to adapt arrange mower tire fastener.
The utility model device can be fixed mowing to be tested according to tested mower size adjustable ground, test process can the mower Large Amplitude Vibration, rotation, has reduced noise, avoids tested mower part to be scattered, simultaneously test loads more accurate, and meets testing standard.
