Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, and in particular to a torque testing machine. Background Technology

[0002] In today's highly industrialized era, connecting cables are ubiquitous in various electronic devices, machinery, and industrial products. The torsional performance of these cables directly affects the stability, reliability, and lifespan of the products. Torque testing machines, as key equipment for accurately testing the torsional force of connecting cables, play a crucial role in ensuring product quality, improving production efficiency, and driving technological development in the industry. From the delicate ribbon cables in electronic products to the power transmission cables in large machinery, torsional testing machines are essential to ensure stable operation under various working conditions, preventing malfunctions such as loose connections and signal transmission interruptions caused by torsional issues.

[0003] In existing technologies for testing cable torque, a common approach is to use a simple manual torque measuring device. This typically consists of an adjustable torque wrench and a simple clamp. The principle is to fix one end of the cable to the clamp, and apply torque to the other end via the wrench. When the wrench reaches a predetermined torque value or slips, the corresponding value is read. This method is simple to operate and low in cost, but in practical applications, it relies entirely on manual operation and lacks automation and accuracy.

[0004] However, this traditional testing method has a core problem: it cannot efficiently measure torque. In actual production, a large number of connecting wires need to be tested for torque. Manual operation is not only time-consuming for each test, but also makes it difficult to guarantee the consistency and accuracy of torque application due to human error. For example, in the mass production of electronic equipment, hundreds or even thousands of connecting wires need to be tested for torque. Using traditional methods, testing a single connecting wire can take several minutes or even longer, which undoubtedly greatly extends the testing time for individual components, leading to a significant reduction in the efficiency of the entire production process. Therefore, a torque testing machine is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a torque testing machine, which aims to improve the problem that the existing technology cannot efficiently measure torque, which prolongs the testing time of individual parts and leads to a significant reduction in the efficiency of the entire production process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0030] 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.

[0031] Reference Figures 1-3 One embodiment of this utility model provides a torque testing machine, comprising:

[0032] Protective shell 1 is typically made of high-strength engineering plastics, such as polycarbonate (PC). Polycarbonate has excellent mechanical strength, effectively resisting external impacts and shocks, providing reliable protection for internal precision components. Protective shell 1 is the main body of the entire device and is used to connect the overall structure.

[0033] Connecting plate 9, which can be made of aluminum alloy, has the characteristics of light weight and high strength. Connecting plate 9 is used to support the fixing plate 6. The side wall of connecting plate 9 is fixedly connected to the inner wall of protective shell 1.

[0034] The rotating platform 8 is generally made of stainless steel. Stainless steel has high strength and hardness, and can withstand the torque and centrifugal force generated during rotation, ensuring the stable and precise rotation of the rotating platform 8. The rotating platform 8 is used to drive the sample clamp 12 to rotate. The bottom of the rotating platform 8 is fixedly connected to the top of the fixed plate 6. The control panel 2 is fixedly connected to the side wall of the protective shell 1. The control panel 2 must have good insulation and a certain mechanical strength. Its outer shell can be made of engineering plastic. The bottom of the protective shell 1 is fixedly connected to the sliding wheel 3, which is usually made of polyurethane rubber. Polyurethane rubber has high elasticity, wear resistance and good rolling performance. The inner wall of the protective shell 1 is fixedly connected to the telescopic rod 5. The output end of the telescopic rod 5 is fixedly connected to the opening and closing door 4. The telescopic rod 5 can be made of high-strength alloy steel. This material has good compressive strength and toughness, and can withstand greater pressure and tension during extension and retraction, ensuring that the opening and closing door 4 can open and close stably and smoothly. The hinged door 4 can be made of aluminum alloy. Aluminum alloy is lightweight, making it easy to open and close, and its corrosion resistance ensures that it will not rust or deform during long-term use. The side wall of the hinged door 4 is slidably connected to the inside of the protective shell 1. The bottom of the fixed plate 6 is fixedly connected to the support column 7, and the bottom of the support column 7 is fixedly connected to another fixed plate 6. The top of the fixed plate 6 is fixedly connected to the slotted plate 10. The slotted plate 10 can be made of carbon structural steel. Carbon structural steel has a certain strength and toughness, which can meet the stress requirements of the slotted plate 10 in the equipment. The side wall of the slotted plate 10 is slidably connected to the positioning pin 11, and the top of the slotted plate 10 is fixedly connected to the three-jaw chuck 14. The three-jaw chuck 14 is usually made of high-quality alloy steel. High-quality alloy steel has high strength and hardness, which can provide sufficient clamping force to ensure that the specimen 13 will not loosen during the test. The top of the fixed plate 6 is fixedly connected to the rotating platform 8, and the top of the rotating platform 8 is fixedly connected to the sample clamp 12. The sample clamp 12 can be made of aluminum alloy. Taking advantage of its light weight and high strength, it can not only ensure the clamping effect of the specimen 13, but also reduce the weight of the rotating part, reduce the load of the rotating platform 8, and improve the operating efficiency of the equipment. The specimen 13 is set on the inner wall of the sample clamp 12, and the outer wall of the specimen 13 is set on the inner wall of the three-jaw chuck 14.

[0035] Specifically, when using a torque testing machine for precise measurements, the first step is to accurately insert the positioning pin 11 into the empty slot plate 10. This step ensures accurate initial positioning for subsequent operations. Next, the specimen 13 to be tested is placed stably on the inner wall of the sample clamp 12. The sample clamp 12 is cleverly designed to fit snugly against the specimen 13. Then, using the clamping function of the sample clamp 12, the specimen 13 is stably held in place, preventing loosening or displacement during subsequent rotation. Next, the connecting wire at one end of the specimen 13 is carefully placed on the inner wall of the three-jaw chuck 14. The three-jaw chuck 14 provides uniform and stable clamping force, firmly securing the connecting wire and preventing it from falling off during the test. Once the specimen 13 and connecting wire are stably clamped, the rotating platform 8 is started. This rotates the sample clamp 12 and the specimen 13 on it smoothly and at a constant speed. This rotation is a crucial step in measuring torque. After rotating for a certain period of time, the positioning pin 11 is pulled out from the empty slot plate 10. At this point, the main structure of the testing machine is in a state where it can rotate freely, ready for the next step of operation. Subsequently, by operating the control panel 2, various parameters of the testing machine can be finely adjusted, including the data acquisition frequency and rotation speed. By precisely controlling these parameters, the efficiency and accuracy of torque measurement can be effectively improved, thereby achieving a good effect of efficient torque measurement. After the test, if it is necessary to inspect or clean the inside of the testing machine, simply pull the opening and closing door 4 gently. The opening and closing door 4 will drive the telescopic rod 5 to retract. The telescopic rod 5 has flexible extension and retraction, making it easy to control the opening and closing of the opening and closing door 4, facilitating the operation of the inside of the testing machine by the staff.

[0036] Working principle: When using the torque testing machine, first insert the positioning pin 11 into the interior of the empty slot plate 10, then place the specimen 13 on the inner wall of the sample clamp 12, and then stably clamp the specimen 13 through the sample clamp 12. Then place the connecting wire at one end of the specimen 13 on the inner wall of the three-jaw chuck 14, and then stably clamp the connecting wire through the three-jaw chuck 14. After the specimen 13 and the connecting wire are both stably clamped, the rotating platform 8 drives the sample clamp 12 to rotate, and after the process, the positioning pin 11 is pulled out. Then, the data and rotation speed are adjusted through the control panel 2 to achieve the effect of efficient torque measurement. Then, pull the opening and closing door 4, and the opening and closing door 4 drives the telescopic rod 5 to retract, which can control the opening and closing of the opening and closing door 4.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
