Abstract
The invention discloses a sliding cover fatigue testing device, which is applied in a system for testing the opening and closing service life of a mobile phone sliding cover, a mobile phone lens sliding cover and sliding covers of various sliding cover-type lens cover digital cameras, and can complete workpiece clamping and service life test in one step. The testing device adopts the principle of a crank sliding block mechanism with variable crank length, and a sliding cover testing head is fixed on a sliding block of the crank sliding block mechanism with variable crank length. After a to-be-tested product is placed on a fixture, the sliding cover testing head is driven by a cylinder to move downwards to be pressed on a sliding cover to be tested. The stroke of the sliding cover testing head can be adjusted by adjusting the length of the variable crank according to the specific opening and closing distance of the sliding cover to be tested, so as to adapt to the opening and closing service life test on various sliding covers to be tested.
Description
Affiliated technical field:
The present invention is that a kind of slip lid that is applied in mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital cameras opens and closes on the fatigue test system, can disposable completion workpiece clamps and the slip lid fatigue test device of testing fatigue.
Background technology:
Mobile phone and all kinds of digital camera be in process of production in order to guarantee the quality of product, be fixedly clamped and test two steps the slip lid of mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital cameras is carried out testing fatigue through goods.Because of the market life cycle of mobile phone and digital camera very short, almost all have new product to release weekly, to the version of all kinds of new products, proving installation also will adapt with it, and a large amount of different testing devices abandoneds is also just arranged for this reason, causes very big waste.Slip lid fatigue test device provided by the invention; Adopt the method for designing of modular organization and flexibility; Through governor motion the fine motion of slip lid measuring head stroke is regulated, made its slip lid that satisfies all kinds of mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital cameras open and close testing fatigue.Realized wide accommodation, the good result that use cost is low.
Summary of the invention:
The present invention has adopted the long slider-crank mechanism principle of variable crank; Designed the switching fatigue test device of a kind of mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital camera slip lids, the slip lid measuring head is fixed on the slide block that becomes the long slider-crank mechanism of crank.After tested goods were placed on the tool, the slip lid measuring head moved down under the driving of cylinder, was pressed on the slip lid to be measured, and according to the concrete folding of slip lid to be measured stroke apart from adjustment slip lid measuring head, just can adapts to all kinds of slip lids switching testing fatigues to be measured.
Technical scheme:
Slip lid measuring head and product to be tested pressing plate move down under the driving of cylinder; As shown in Figure 1; Adopt the long slider-crank mechanism of variable crank; The length of regulating crank through crank length adjustment screw rod, thus realize the fine motion of slide block reciprocating stroke is regulated, satisfy the requirement of all kinds of slip lid testing fatigues.After tested goods are placed on the tool by operating personnel by hand.Moved cross beam, moves down through line slideway is parallel under the driving of pressing the test specimen cylinder together with the test macro of fixing on it.Its result is pressed abd fixed on measured workpiece in the tool test specimen fixed head under the control of test specimen holddown spring, the measuring head that reciprocatingly moves simultaneously also is pressed on the slip lid of measured workpiece.Then, the motor-driven crank rotates, and drives measuring head through connecting rod and under the constraint of line slideway, does linear reciprocating motion, thereby realize the testing fatigue that slip lid opens and closes.
The invention has the beneficial effects as follows:
The present invention is that a kind of slip lid that is applied in mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital cameras opens and closes on the fatigue test system.The market life cycle that has solved mobile phone and digital camera is very short, and a large amount of proving installation abandoneds is arranged for this reason, causes the problem of very big waste.Slip lid fatigue test device provided by the invention, the method for designing of employing modular organization and flexibility, the slip lid that has satisfied all kinds of mobile phone sliding covers, mobile lens slip lid and all kinds of sliding cover type lens case digital cameras through governor motion opens and closes testing fatigue.Realized wide accommodation, the good result that use cost is low.

Embodiment:
As shown in Figure 2, after measured workpiece (14) is placed on the tool (15).Moved cross beam (10) together with fixing measuring head drive motor (9), measuring head fixed head (17), measuring head (18), measured workpiece holddown spring (12), slide block (1), slide block mobile and horizontal guide rail (2), connecting rod (3), crank (4) on it under the driving of pressing test specimen cylinder (8), through parallel the moving down of constraint of vertical slipper (11) and line slideway (13).Its result; Measuring head fixed head (17) is pressed abd fixed on measured workpiece (14) in the tool (15) under the control of measured workpiece holddown spring (12); Measuring head (18) passes the square hole of measuring head fixed head (17) center section then, also is pressed on the slip lid of measured workpiece (14) according to predetermined pressure.System sends signal through the sensor of pressing test specimen cylinder (8) down stroke extreme position; Making measuring head drive motor (9) drive crank (4) rotates; Drive measuring head (18) through connecting rod (3) and under the constraint of slide block mobile and horizontal guide rail (2), do linear reciprocating motion; The slip lid that measuring head (18) utilizes friction force to promote measured workpiece (14) opens and closes, and realizes testing fatigue.For skidding between the slip lid that prevents measuring head (18) and measured workpiece (14), influence test result, be provided with photoelectric sensor in the slip lid top of measured workpiece (14), detect the switching of slip lid in real time.
The present invention has adopted the long slider-crank mechanism principle of variable crank; As shown in Figure 1; According to the concrete folding distance of slip lid to be measured, regulate the position of crank length adjustment slide block (6) through turn crank length adjustment screw rod (5), thereby change the length of crank (4); Realization is to the adjusting of slide block (1) and measuring head (18) stroke that is fixed together with it, to adapt to all kinds of slip lids switching testing fatigues to be measured.More accurate for the motion that makes slip lid measuring head (18), with the slide block (1) that slip lid measuring head (18) is fixed together, form moving sets with high-precision slide block mobile and horizontal guide rail (2), realize accurately motion.
