实施例1Example 1

如图1所示,一种批量检测弹簧劲度系数的装置,包括固定座1、直线导轨2、多个滑动连接在直线导轨2上的滑块3、用于牵引所述滑块3在直线导轨2上滑动的牵引机构4、用于检测所述滑块3位移量的位移检测机构5以及用于根据所述牵引机构4的牵引力大小和位移检测机构5检测的滑块3位移量计算弹簧劲度系数的计算单元6,所述固定座1固定设置在直线导轨2的前端,所述牵引机构4设于直线导轨2的后端,所述滑块3并排间隔设置在固定座1与牵引机构4之间,所述位移检测机构5与计算单元6连接。As shown in Figure 1, a kind of device that detects spring stiffness coefficient in batches, comprises fixed seat 1, linear guide rail 2, a plurality of slide blocks 3 that are slidably connected on linear guide rail 2, is used for pulling described slide block 3 in a straight line The traction mechanism 4 sliding on the guide rail 2, the displacement detection mechanism 5 for detecting the displacement of the slider 3, and the spring for calculating the displacement of the slider 3 detected by the traction force of the traction mechanism 4 and the displacement detection mechanism 5 Stiffness coefficient calculation unit 6, the fixed seat 1 is fixedly arranged on the front end of the linear guide rail 2, the traction mechanism 4 is arranged on the rear end of the linear guide rail 2, and the sliders 3 are arranged side by side at intervals between the fixed seat 1 and the traction Between the mechanisms 4 , the displacement detection mechanism 5 is connected with the computing unit 6 .

上述实施方式提供的批量检测弹簧劲度系数的装置中,先通过多个滑块3将各弹簧串联起来,将最前端的弹簧连接于固定座1,并使各弹簧处于自然状态,再通过牵引机构4以一定大小为F的力拉动滑块3,此时每根弹簧的受力大小均为F(选择高精度的滑轨副,这样就可以保证滑块与直线导轨间摩擦系数极小,使得摩擦力对拉力的影响极小,可以忽略不计),在拉动一段距离后停下牵引机构4,使得各弹簧处于静止的拉伸状态,这时连接该弹簧的两个滑块3的位移量之差即为弹簧的拉伸量s,通过公式k=F/s即可计算出弹簧的劲度系数k值。其中,滑块3的位移量由位移检测机构提供给计算单元6,计算单元6根据连接弹簧两端滑块3的位移量计算出二者的差值,即可得到弹簧的拉伸量s,再根据牵引机构4提供的牵引力F值和公式k=F/s就可计算出对应弹簧的劲度系数k值。通过以上描述可以看出,本实用新型提供的检测装置可以一次检测多根弹簧的劲度系数,其对弹簧的长度没有限制,各待测弹簧长度及劲度系数均可以不同,具有较高的检测效率,特别适合弹簧生产工厂批量检测使用。In the device for detecting spring stiffness coefficients in batches provided by the above embodiment, the springs are first connected in series through a plurality of sliders 3, the frontmost spring is connected to the fixed seat 1, and the springs are in a natural state, and then the springs are pulled in a natural state. The mechanism 4 pulls the slider 3 with a certain force of F. At this time, the force of each spring is F (select a high-precision slide rail pair, so that the friction coefficient between the slider and the linear guide rail can be guaranteed to be extremely small. The influence of the frictional force on the pulling force is very small and can be ignored), and the traction mechanism 4 is stopped after pulling for a certain distance, so that each spring is in a static tension state. At this time, the displacement of the two sliders 3 connected to the spring The difference is the stretching amount s of the spring, and the stiffness coefficient k value of the spring can be calculated by the formula k=F/s. Wherein, the displacement of the slider 3 is provided to the calculation unit 6 by the displacement detection mechanism, and the calculation unit 6 calculates the difference between the displacements of the slider 3 at both ends of the connecting spring to obtain the stretching amount s of the spring, Then according to the traction force F value provided by the traction mechanism 4 and the formula k=F/s, the stiffness coefficient k value of the corresponding spring can be calculated. As can be seen from the above description, the detection device provided by the utility model can detect the stiffness coefficients of multiple springs at one time, and there is no limit to the length of the springs. The lengths and stiffness coefficients of each spring to be tested can be different, and have higher High detection efficiency, especially suitable for batch detection in spring production factories.

进一步,位移检测机构5包括滑动变阻器、电阻测量单元和处理器,滑动变阻器包括电阻丝和多块滑片,每个滑块3对应连接一块滑片,滑片抵靠在电阻丝上,滑片及电阻丝的一端连接电阻测量单元,电阻测量单元与处理器连接,处理器与计算单元6连接,处理器根据电阻测量单元测得的电阻值变化可计算出滑块3的位移量,使用滑动变阻器、电阻测量单元和处理器组成的位移传感器可使信号输出更灵敏、使用寿命长。Further, the displacement detection mechanism 5 includes a sliding rheostat, a resistance measuring unit and a processor. The sliding rheostat includes a resistance wire and a plurality of sliders. Each slider 3 is correspondingly connected to a slider, and the slider leans against the resistance wire. and one end of the resistance wire is connected to the resistance measuring unit, the resistance measuring unit is connected to the processor, and the processor is connected to the calculation unit 6, and the processor can calculate the displacement of the slider 3 according to the change of the resistance value measured by the resistance measuring unit. The displacement sensor composed of a rheostat, a resistance measuring unit and a processor can make the signal output more sensitive and have a long service life.

再进一步,还包括一工作台7,所述固定座1、直线导轨2以及牵引机构4均安装在工作台7上,在本实施例中,工作台7台面为水平面,以方便调整各个设备,保证检测结果的稳定性。Further, it also includes a workbench 7, the fixed seat 1, the linear guide rail 2 and the traction mechanism 4 are all installed on the workbench 7, in this embodiment, the workbench 7 table is a horizontal plane, to facilitate the adjustment of each equipment, Ensure the stability of test results.

再进一步,还可以在固定座1的后端面以及滑块3的前端面和后端面上均设置用于挂住待测弹簧的挂环,从而便于快速地将弹簧勾在固定座1或滑块3上,进一步提高检测效率。Still further, a hanging ring for hanging the spring to be measured can also be arranged on the rear end face of the fixed seat 1 and the front end face and the rear end face of the slide block 3, thereby facilitating the spring to be hooked on the fixed seat 1 or the slide block quickly 3, to further improve the detection efficiency.

再进一步,牵引机构4包括电缸4a,电缸4a的活塞杆顶端设有用于扣住滑块3上挂环的挂扣,使用电缸4a提供牵引力来拉动弹簧,效果稳定,可控性好。Further, the traction mechanism 4 includes an electric cylinder 4a, the top of the piston rod of the electric cylinder 4a is provided with a buckle for fastening the hanging ring on the slider 3, and the electric cylinder 4a is used to provide traction to pull the spring, the effect is stable and the controllability is good .

需要进一步说明的是,可先通过计力器来确定电缸4a的活塞杆伸缩一定距离(例如活塞杆伸缩至极限程度)时所产生的拉力大小,由于保证该拉伸距离不变即可保证该拉力值固定不变,故在之后的弹簧检测工作中能预先将该拉力的大小(即F)输入到控制器中,待检测弹簧时每次均使活塞杆伸缩至预定的距离,即可直接使用该拉力大小进行相关的运算。It should be further explained that the force gauge can first be used to determine the magnitude of the pulling force generated when the piston rod of the electric cylinder 4a is stretched for a certain distance (for example, the piston rod is stretched to the limit), since the stretching distance can be guaranteed to be constant The tension value is fixed, so in the subsequent spring detection work, the magnitude of the tension (ie F) can be input into the controller in advance, and the piston rod is stretched to a predetermined distance each time when the spring is to be detected. Directly use the pulling force to perform related calculations.

进一步,如图2所示,可以在直线导轨2的两侧壁开设V形槽,在滑块3上设置与V形槽相匹配的凸起,然后在凸起上设置由多个呈直线排列的滚珠,使滚珠抵靠住V形槽的内壁,这样可使滑块3在直线导轨2上滑动时更加顺畅,并且使得二者之间的摩擦方式变为滚动摩擦,其摩擦系数极小,可提高滑块3滑动时的顺畅性。Further, as shown in Figure 2, V-shaped grooves can be set on the two side walls of the linear guide rail 2, and a protrusion matching the V-shaped groove is provided on the slider 3, and then a plurality of linearly arranged protrusions are arranged on the protrusion. The balls are used to make the balls lean against the inner wall of the V-shaped groove, which can make the slider 3 slide more smoothly on the linear guide rail 2, and make the friction between the two become rolling friction, and the friction coefficient is extremely small. The smoothness when the slider 3 slides can be improved.
