In the time of by bike, the bicyclist is sitting on the cushion, and both hands walker handle is trampled foot-operatedly with both feet, utilize crank to drive sprocket rotation, rotates by the chain drive trailing wheel, reaches the purpose that moves ahead.On cities and towns, backroad, relatively jolt in some highway section, and the general assembly (TW) of bicyclist and bicycle is bigger again, and therefore, bicycle can relatively jolt.Jolting is delivered to handlebar through wheel, front fork, is delivered to handlebar and cushion through trailing wheel and vehicle frame simultaneously, when the bicyclist is felt under the weather, also parts such as front fork is produced shock and vibration, easily makes parts impaired.And the stress of front fork is comparatively complicated, and is changeable, and power vertical, horizontal, level has; The front fork that has now simultaneously adopts shock-proof front-fork assembly, the back is installed generally becomes 20 ° of angles with ground, and therefore the power that is subjected to also tilts.For the quality of the parts that guarantee to dispatch from the factory good, before dispatching from the factory, need front fork is detected, but there is not a kind of pick-up unit can carry out the quality testing of front fork at present, general also can only be to judge according to workman's experience, perhaps through visual detection, the omission accident taking place easily, cause to exist the front fork of quality problems to dispatch from the factory, brings potential safety hazard to the bicyclist.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of automatic control that can pass through computing machine, fatigue testing machine for bicycle front fork to the fatigue strength of bicycle front fork accurately detects can detect the front fork application of force from different directions.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of fatigue testing machine for bicycle front fork, it is characterized in that comprising that body 1, cylinder mount pad 11, cylinder 3, displacement transducer 4, force transducer 5, connecting rod 6, vacation show front axle 7, anchor clamps 9, mount pad 10 and support 2, support 2 is installed on the body 13, side at support 2 is installed two cylinder mount pads 11, on cylinder mount pad 11, flexibly connect cylinder 3 respectively, the piston rod top of cylinder 3 connects connecting rod 6, the top of two connecting rods 6 is contained in a vacation and shows on the front axle 7, also is respectively equipped with displacement transducer 4 and force transducer 5 on the piston rod of cylinder 3; On body 1, also be provided with mount pad 10, on mount pad 10, be fixed with anchor clamps 9.
Aforesaid fatigue testing machine for bicycle front fork is characterized in that having chute on described body 1, in the bottom of mount pad 10 processing porose, seal in bolt in the hole, the head of described bolt matches usefulness nut fixed mounting 10 with chute on the body 1.
Aforesaid fatigue testing machine for bicycle front fork is characterized in that having chute on support 2, processes porosely on two cylinder mount pads 11 respectively, seals in bolt in the hole, and the head of described bolt cooperates with chute on the support 2, with the fixing cylinder mount pad 11 of nut.
Aforesaid fatigue testing machine for bicycle front fork is characterized in that being respectively equipped with solenoid valve on the air feed gas circuit of two cylinders 3, and described solenoid valve, displacement transducer 4, force transducer 5 link to each other with outer computer by signal wire.
The invention has the beneficial effects as follows: the present invention is simple in structure, and convenient test can realize the accurate detection to the fatigue strength of bicycle front fork, and can realize the reinforcing of different directions, automatically control, analyze and load, the quality of the accessory that guaranteed to dispatch from the factory is good, has guaranteed bicyclist's personal safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done concrete being described below.
Fig. 1 is a structural representation of the present invention.As shown in the figure, fatigue testing machine for bicycle front fork of the present invention, comprise body 1, cylinder 3, cylinder mount pad 11, displacement transducer 4, force transducer 5, connecting rod 6, front axle 7 is shown in vacation, anchor clamps 9, mount pad 10 and support 2, support 2 is installed on the body 1, on support 2, have chute, difference machining hole on two cylinder mount pads 11, the head of bolt is matched with chute on the support 2, threaded portion passes the hole on the cylinder mount pad 11, use bolt, nut is cylinder mount pad 11 fixedly, make that the upper-lower position of cylinder mount pad 11 is adjustable, can use the front fork that is applicable to various models, and can realize the reinforcing of all directions.
Flexibly connect cylinder 3 respectively on two cylinder mount pads 11, the top of 6, two connecting rods 6 of piston rod top connection connecting rod of cylinder 3 is contained in a vacation jointly and shows on the front axle 7.On the piston rod of cylinder 13, be provided with displacement transducer 4 and force transducer 5.
Also be provided with mount pad 10 on body 1, offer chute on the body 1, match with chute with the head of bolt, the bottom processing of mount pad 10 is porose, and the threaded portion of bolt passes from the hole, and is with nuts and bolt that mount pad 10 is fixing.Like this, mount pad can move left and right also be fixed on body 1, can realize the front fork of different length is detected.On mount pad 10, be fixed with anchor clamps 9.
On the air feed gas circuit of cylinder 11, solenoid valve is set, solenoid valve, displacement transducer 12, force transducer 10 are linked to each other with outer computer by signal wire, the signal of being gathered is passed to outer computer, and by the action of outer computer control electromagnetic valve, and dynamically flex one's muscle, the real-time curve of frequency etc.
