Multi-station spring detection test bed

Abstract

The invention discloses a multi-station spring detection test bed. The test bed comprises a rack, a detection table is erected on the rack, and a tension spring detection station, a pressure spring detection station and a torsion spring detection station are sequentially arranged on the detection table, wherein the tension spring detection station comprises an upper pull plate and a lower pull plate which move up and down, upright posts which are mutually corresponding and used for hanging two ends of a spring are respectively arranged on the corresponding end surfaces of the upper pull plateand the lower pull plate, and hanging holes are respectively arranged at the end parts of the upright posts; the pressure spring detection station comprises an upper pressure plate and a lower pressure plate which move up and down, the corresponding end surfaces of the upper pressure plate and the lower pressure plate are respectively provided with an upper spring clamping seat and a lower springclamping seat which are correspondingly matched with each other, and the upper spring clamping seat and the lower spring clamping seat are respectively provided with a clamping hole which is corresponding to each other; and the torsion spring detection station comprises a torsion spring clamping plate, and clamping grooves which are radially arranged and used for clamping springs are distributed on the torsion spring clamping plate. The multi-station spring detection test bed has the advantages of convenience in control, high working efficiency, capability of simultaneously realizing online work of tension, pressure and torsion, stability in work and the like.

Description

[0001] Technical field: [0002] The invention relates to the field of spring detection, and mainly relates to a multi-station spring detection test bench. [0003] Background technique: [0004] The main working process of the existing spring testing machine is to stretch the fixed hooks at both ends of the extension spring. The stretching speed is relatively slow. After stretching to the set value, record the corresponding parameters, and it is impossible to accurately determine its fatigue performance. Its working principle is to stretch the spring by moving a threaded shaft on the line. During the stretching process, the friction sound is louder. The tension sensor displays the stretching force value N stretched to the set stroke value of the spring. Generally, the spring used for forklifts Most of them are the hand and foot brake system. The tension spring adopts the hook type suspension on the connecting rod. It has high requirements for the fatigue wear of the hook, and ...

[0004] The main working process of the existing spring testing machine is to stretch the fixed hooks at both ends of the extension spring. The stretching speed is relatively slow. After stretching to the set value, record the corresponding parameters, and it is impossible to accurately determine its fatigue performance.

Its working principle is to stretch the spring by moving a threaded shaft on the line. During the stretching process, the friction sound is louder. The tension sensor displays the stretching force value N stretched to the set stroke value of the spring. Generally, the spring used for forklifts Most of them are the hand and foot brake system. The tension spring adopts the hook type suspension on the connecting rod. It has high requirements for the fatigue wear of the hook, and it is also the point where the tension spring is easy to break. Before the improvement, the function of the existing test bench is not effective. Fatigue test function

At the same time, because the design object of the existing test bench is only a single tension spring detection, it cannot meet the detection of torsion springs, compression springs and other products that appear in the continuous updating of products, and cannot meet the detection requirements of high-precision products.

[0005] Moreover, the function of the existing tensile testing machine for detecting springs is too single, and it cannot effectively verify the fatigue performance of springs. It can only be used for simple tensile test measurements of tension springs. The test speed is relatively slow, and the general test period can reach 3 to 6 months. ; The time period is long and the efficiency is low

It is impossible to do effective detection tests on torsion springs and compression springs, and the single function is more obvious
