Technical Field

[0001] This utility model relates to the field of mechanical performance testing, and in particular to a spring tension tester. Background Technology

[0002] With the development of industrial manufacturing and science and technology, springs, as key components in fields such as machinery, automobiles, and aerospace, have a crucial impact on the overall performance of products. Therefore, conducting precise tensile tests on springs has become an important step in ensuring product quality and safety.

[0003] Tensile testing equipment tests the strength and durability of materials by applying tensile force to determine whether the materials meet requirements. This testing equipment can not only measure mechanical parameters such as tensile strength, modulus of elasticity, and elongation, but also perform random checks on products during production to ensure they meet specified tensile standards.

[0004] Existing tensile testers are mostly used to test a single product or a single type of product, and cannot measure multiple products or multiple types of products at the same time. In the case of spring tensile testers, it is impossible to perform tensile tests on multiple or various types of springs. Utility Model Content

[0005] To address the problem that existing spring tension testers cannot perform tension tests on multiple springs, this utility model provides a spring tension tester, comprising: a base, a bracket, a crossbar, a fixed seat, a lifting mechanism, a connecting rod, a tension gauge, and a hook;

[0006] The base has a fixed seat on its upper surface, which can hook one end of the spring. The bracket is a rectangular frame missing one side. The bracket is installed on the upper surface of the base, and the fixed seat is located directly below the bracket. There are two lifting mechanisms, which are mirror images of each other and installed inside the bracket. The lifting mechanism has a scale along its axial direction. The lifting mechanism consists of a ball screw and a nut. A lifting component is installed on the nut. The lifting component can move up and down under the drive of the nut. Both ends of the crossbar are fixedly connected to the lifting component. One end of the connecting rod is fixed to the bottom surface of the crossbar, and the other end is fixed to the tension gauge. The bottom end of the tension gauge is detachably connected to the hook.

[0007] In a preferred embodiment of this invention, the fixing base is composed of a slide rail and a slider. The slide rail is fixed to the base, and the slider can slide on the slide rail without falling off. One end of the spring can be fixed to the surface of the slider.

[0008] As a preferred embodiment of this utility model, the top of the lifting mechanism is equipped with a motor, and the lead screw of the lifting component can rotate under the drive of the motor.

[0009] As a preferred embodiment of this utility model, a baffle is detachably mounted on the surface of the lifting component, the baffle has screw holes, and both ends of the crossbar can be placed on the baffle and reinforced with screws.

[0010] As a preferred embodiment of this utility model, the upper surface of the baffle has vertically fixed side plates on both sides, and the distance between the two side plates is equal to the width of the crossbar.

[0011] As a preferred embodiment of this utility model, the connecting rod is telescopic and has holes on its surface, into which bolts can be inserted, and the length of the bolts is greater than or equal to the diameter of the connecting rod.

[0012] As a preferred embodiment of this utility model, a back plate with the same area as the bracket is fixed on one side of the bracket, and a tempered glass plate with the same area as the bracket is installed on the other side. The installation method is to connect the bracket side with hinges.

[0013] In a preferred embodiment of this invention, the side plate and the baffle are integrally formed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention allows for the installation of multiple connecting rods and force gauges, enabling the tensile testing instrument to simultaneously test multiple springs with different elastic coefficients. This significantly improves the efficiency and convenience of spring testing. The use of a ball screw for lifting also makes the instrument more stable during control of lifting. Furthermore, this invention provides different installation methods for the crossbar, increasing the convenience of replacing parts.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0025] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0026] In the embodiments, such as Figure 1-6 As shown, this utility model provides a spring tension tester, characterized in that it includes a base 1, a bracket 2, a crossbar 3, a fixed seat 11, a lifting mechanism 21, a connecting rod 31, a tension gauge 32, and a hook 33;

[0027] The base 1 has a fixed seat 11 on its upper surface, which can hook one end of the spring. The bracket 2 is a rectangular frame missing one side. The bracket 2 is installed on the upper surface of the base 1, and the fixed seat 11 is located directly below the bracket 2. There are two lifting mechanisms 21, which are mirror images of each other and installed inside the bracket 2. The lifting mechanism 21 has a scale along its axial direction. The lifting mechanism 21 consists of a ball screw and a nut. A lifting component 212 is installed on the nut. The lifting component 212 can move up and down under the drive of the nut. The two ends of the crossbar 3 are fixedly connected to the lifting component 212. One end of the connecting rod 31 is fixed to the bottom surface of the crossbar 3, and the other end is fixed to the tension gauge 32. The bottom end of the tension gauge 32 is detachably connected to the hook 33.

[0028] During operation, hang one end of the spring on the fixed base and the other end on the hook. If the spring is too long or too short, adjust the telescopic rod to achieve the appropriate hanging length before hanging. After hanging the spring, start the lifting device. As the lifting mechanism rises, the tension value can be observed on the tension gauge. By combining the lifting distance, you can determine whether the spring's elasticity meets the requirements.

[0029] The use of a slider and a slide rail allows for easy fine-tuning of the position of the fixing seat during testing, ensuring the correct position of the spring. In a preferred embodiment of this invention, the fixing seat 11 is composed of a slide rail 111 and a slider 112. The slide rail 111 is fixed to the base 1, and the slider 112 can slide on the slide rail 111 without falling off. One end of the spring can be fixed to the upper surface of the slider 112.

[0030] Using a motor drive allows for better control of the lifting and lowering, preventing uneven lifting distances on both sides of the crossbar. In a preferred embodiment of this invention, a motor 211 is mounted on the top of the lifting mechanism 21, and the lead screw of the lifting component 212 can rotate under the drive of the motor 211.

[0031] Using a baffle for support and securing it with screws can keep the crossbar stable and prevent it from falling off. As a further embodiment, a baffle 213 is detachably mounted on the surface of the lifting component 212. The baffle 213 has screw holes, and both ends of the crossbar 3 can be placed on the baffle 213 and secured with screws.

[0032] Using double side plates allows the crossbar to be clamped within them, facilitating assembly and disassembly and eliminating the need for screws. As a further embodiment, the upper surface of the baffle 213 has vertically fixed side plates 214 on both sides, the distance between the two side plates 214 being equal to the width of the crossbar 3.

[0033] The integrated design makes the device more robust. As a further embodiment, the side plate 214 and the baffle 213 are integrally formed.

[0034] The use of a telescopic connecting rod facilitates the installation of springs of varying lengths. In a preferred embodiment of this invention, the connecting rod 31 is telescopic and has a hole 312 on its surface into which a bolt 311 can be inserted. The bolt 311 has a length greater than or equal to the diameter of the connecting rod 31.

[0035] Using a baffle and tempered glass plate to enclose the operating space can prevent poor-quality springs from breaking and flying out, causing injury. In a preferred embodiment of this invention, one side of the bracket 2 is fixed with a back plate of the same area as the bracket 2, and the other side is fitted with a tempered glass plate 22 of the same area as the bracket 2. The installation method is to connect the bracket 2 to the side using hinges.
