Summary of the invention
Object of the present invention produces thus, proposes a kind of nonmetallic materials fatigue bending machine.
By improving the accuracy and science that detect nonmetallic materials (friction material) bending fatigue Resisting fractre ability, avoid manual detection batten flexural loading uneven, flexural deformation angle disunity, testing result is by the drawback of the impact of human factor, effectively reduce labour intensity, improve the accuracy of detection efficiency and detection.
The present invention realizes the technical scheme that above-mentioned purpose takes: a kind of nonmetallic materials or friction material fatigue bending machine, form primarily of the drive transmission device of installing frame in chassis body, tilting mechanism and clamp mechanism, drive transmission device is by being straight reciprocating motion by the convert rotational motion of motor, thus drive tilting mechanism swinging centered by transmission shaft, the upper grip of the clamp mechanism be assemblied on tilting mechanism is also moved thereupon, realizes the torture test that bends right and left to the nonmetallic materials be arranged on clamp mechanism/friction material batten.
Drive transmission device of the present invention is ordered about connecting rod and is promoted the tooth bar of tilting mechanism by the rocking bar that rotarily drives of motor and do straight reciprocating motion, about the periodicity straight reciprocating motion of tooth bar being converted into centered by transmission shaft with tooth bar meshed gears, 180 degree swing, swing together with the swing arm that drive and transmission shaft connect, the upper grip be assemblied on swing arm is also moved thereupon.
Drive transmission device of the present invention comprises connecting rod, motor and rocking bar, and the output terminal of motor is fixedly connected with one end of connecting rod by rocking bar; Described tilting mechanism comprises tooth bar, gear, transmission shaft and swing arm, and tooth bar is connected with the connecting rod of drive transmission device, and wheel and rack is connected with a joggle, and gear is arranged on rack fixing seat by transmission shaft, is fixedly connected with swing arm in one end of transmission shaft; Described clamp mechanism comprises upper grip and lower chuck, and upper grip is arranged on the swing arm of tilting mechanism, and lower chuck is installed in the chassis body below swing arm.
The present invention is provided with chute on the top of described swing arm, and described upper grip is arranged in this chute.
The present invention is the special inspecting equipment of nonmetallic materials (friction material) bending fatigue Resisting fractre ability, solve batten flexural loading in existing testing process uneven, flexural deformation angle disunity, testing result is subject to the impact of human factor, the problem that labour intensity is large, detection efficiency is low.
Drive and mechanical drive owing to have employed motor, the power that testing machine produces when bending at every turn batten is balanced, and angle of bend unification is 180 degree, then the accuracy of the test improved further.Owing to have employed counter, therefore, this testing machine can accurate recording number of bends, and testing result can not by the impact of human factor.Can quick-clamping batten, only complete within 5 seconds from unloading batten to the next batten of clamping.And can carry out to batten the action that continuation bends right and left, and wobble frequency rate realizes changing by adjustment motor speed.Effective accuracy and science improving detection nonmetallic materials (friction material) bending fatigue Resisting fractre ability, reduces labour intensity, improves the accuracy of detection efficiency and detection.
