Description

Pedal sleeve pulling-out force detection equipment Technical Field The utility model belongs to the field of automobile part detection, and particularly relates to pedal sleeve pulling-out force detection equipment. Background The pedal sleeve of the automobile brake pedal and the clutch pedal plays an extremely important role in the whole automobile, namely 1) the anti-skid and operation stability, namely the brake pedal sleeve is usually designed by adopting rubber, metal or anti-skid textures, so that the friction force between feet and the pedal can be increased, the feet are prevented from slipping when the driver steps on the automobile in rainy and snowy days or when the soles of the driver are wet, and the operation accuracy in emergency braking is ensured. 2) Protecting the pedal of the original factory, and possibly causing abrasion or corrosion of the surface of the pedal of the original factory after long-term use. The pedal sleeve can reduce the direct abrasion of the metal or plastic pedal and prolong the service life. 3) The pedal sleeve is made of soft materials, so that the fatigue feeling of long-time treading can be relieved, and the pedal sleeve is particularly suitable for urban road conditions requiring frequent braking. 4) And the functional areas are distinguished, so that a driver is helped to quickly identify the position of the brake pedal, and the risk of mistakenly stepping on the accelerator is reduced. If the pedal sleeve falls off during operation of the vehicle, this has the serious consequence that 1) the risk of sudden braking slip is caused by the core of the pedal sleeve being the increased friction, which falls off, which results in a smooth pedal surface, in particular of metal or plastic material. In rainy and snowy days or when the soles of drivers are wet, feet are easy to slip during emergency braking, and braking delay and even failure can be caused. 2) Abnormal pedal travel interference, namely, falling residual fragments can be blocked into a brake pedal mechanical structure, so that pedal stepping resistance is increased or rebound is abnormal, and the brake response speed is influenced. 3) The abrasion of the pedal in the original factory is accelerated, the exposed metal/plastic pedal is easily scratched by hard objects of the sole in long-term treading, and the strength of metal parts is possibly reduced due to oxidation corrosion, so that the service life is shortened. 4) Foreign matter invasion risk is that sediment, liquid and the like can enter the pedal rotating shaft area more easily after the pedal sleeve is lost, so that lubrication is invalid or rusted, and pedal clamping stagnation can be caused under extreme conditions. 5) Muscle memory disturbance, the driver who gets to the thickness of the pedal sleeve may have control errors (such as misjudgment of pedal height) due to sudden loss, and especially may misstep on the accelerator in emergency. 6) The touch feedback is lost, the pedal sleeve with partial textures or bulges can help a driver to quickly position the pedal, and the pedal sleeve falls off to cause difficult positioning during blind operation, so that the night driving is particularly dangerous. In order to ensure the safety of the running of the automobile, the pull-out force test of the pedal sleeve is particularly important. At present, the conventional detection mode is that an inspector directly holds the push-pull force meter, presses four corners of the pedal sleeve with force, and then reads out the falling-off value. However, the detection mode has two problems that 1) in the process of pushing and pulling the four corners of the pedal sleeve, the uniformity of the pushing and pulling process cannot be ensured because of the handheld mode, so that the process has certain acceleration, different detection personnel can obtain different results, the repeatability is poor and the difference is large. Disclosure of utility model The utility model provides pedal sleeve pulling-out force detection equipment, and aims to solve the problem of low accuracy of the existing detection mode. In order to solve the technical problems, the technical scheme is that the pedal sleeve pulling-out force detection device comprises a bench and is characterized by further comprising a moving table, a push-pull force gauge, a lifting mechanism and a pedal sleeve tool, wherein the moving table is fixed on the table top of the bench, the push-pull force gauge can move back and forth and left and right through the moving table, the lifting mechanism is fixed on the table top of the bench, the pedal sleeve tool can move up and down through the lifting mechanism, the pedal sleeve tool is used for fixing a pedal sleeve, and the push-pull force gauge is used for applying thrust to four corners of the pedal sleeve. The technical scheme is further limited, the mobile station is structurally characterized by comprising a lower base, wherein a horizontal lower l
