Abstract
Description
Technical Field
[0001] The invention relates to the field of size and load detection of springs after online forming, and in particular to a portable digital display load machine. Background Art
[0002] In modern industrial production, especially in the field of spring manufacturing, quality inspection of springs is of vital importance. With the expansion of production scale and the diversification of production scenarios, there is an increasing demand for equipment that can quickly and accurately detect spring loads and dimensions on site. Traditional testing equipment is often large in size and requires a dedicated testing site. It cannot be flexibly moved between different workstations in the workshop or different production areas, which limits the efficiency of testing and the timeliness of production. Moreover, traditional equipment is gradually unable to meet the increasingly complex production requirements in terms of ease of operation, data accuracy and versatility. This has prompted the development and application of portable digital load machines to meet the efficient, flexible and accurate testing needs of modern production.
[0003] Common spring testing machines in the prior art usually adopt a more complex mechanical structure. For example, some large spring testing equipment will have a fixed testing stand with multiple power drive devices and transmission mechanisms installed on the stand. When measuring the spring load, the motor drives the screw to rotate, which in turn drives the pressure plate to squeeze the spring. The pressure measurement relies on the pressure sensor installed under the pressure plate. The sensor transmits the pressure signal to the connected computer or instrument for data display. For the measurement of spring size, it is necessary to use tools such as calipers to manually measure and record the readings. When operating equipment with this structure, professionals are required to debug and operate each power device and transmission mechanism, and the installation and maintenance of the equipment require a large space and professional technical support.
[0004] There are many inconveniences in the existing technology. Due to the complex structure and large size of the equipment, its portability is extremely poor, and it is impossible to test the springs in time at the production site. The springs often need to be transported to a special testing room, which not only consumes a lot of manpower and time, but also easily causes damage to the springs during transportation, affecting the accuracy of the test results. In addition, since the equipment for measuring load and size is independent of each other, the operation process is cumbersome, and convenient integrated measurement cannot be achieved, resulting in low overall detection efficiency, which is difficult to meet the requirements of fast, efficient and accurate detection in modern spring production. A new type of detection equipment that can overcome these problems is urgently needed to improve the quality and efficiency of spring detection. For this reason, a portable digital load machine is proposed to solve the above problems. Summary of the invention
[0005] In order to make up for the above shortcomings, the present invention provides a portable digital load cell, aiming to improve the problems in the prior art that the device cannot be conveniently moved, cannot quickly switch between different formats, and cannot perform individual detection.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] As a further description of the above technical solution:
[0010] The measuring assembly comprises a digital micrometer and a load sensor, and the outer wall of the digital micrometer is slidably connected to the inside of the meter head fixing seat;
[0011] As a further description of the above technical solution:
[0012] The meter head fixing seat is in a circular ring shape to wrap the digital micrometer, thereby providing a stabilizing effect on the digital micrometer;

[0015] As a further description of the above technical solution:
[0016] The bottom of the load sensor is fixedly connected to the top of the base, and one side of the load sensor is arranged at the other end of the spring workpiece;
[0017] As a further description of the above technical solution:
[0018] The spring workpiece is arranged between the balancing pressure block and the load sensor, and is clamped and measured.
[0019] The present invention has the following beneficial effects:
[0020] In the present invention, a digital micrometer is used to drive a balancing pressure block to squeeze a spring workpiece, and when the value set on the load display panel is reached, convenient measurement is performed through feedback from a load sensor. The overall device is compact and convenient to carry, and a bearing is arranged inside the balancing pressure block to prevent the spring workpiece from rotating during rotation and affecting the measurement.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] Reference Figure 1-Figure 3 , an embodiment provided by the present invention: a portable digital load meter, including a base 1 and a measuring component. The base 1 is used as the basic support part of the whole device and is cast from a solid and lightweight aluminum alloy material. This material can not only ensure that the base 1 has sufficient strength and stability to bear the weight of the chassis 2 and other components and ensure that no shaking or displacement occurs during the measurement process, but also helps to reduce the overall weight of the device and facilitate carrying and moving. The top of the base 1 is fixedly connected to the chassis 2. The shell of the chassis 2 is made of high-strength engineering plastics, which has good wear resistance and impact resistance, and can effectively protect the internal electronic components and mechanical structures from interference and damage from external environmental factors. A control component is arranged on the top of the chassis 2, and a meter head fixing seat 5 is fixedly connected to the top of the base 1;
[0028] The control component includes a load display panel 3 and a power switch 4. The load display panel 3 is arranged on the outer wall of the chassis 2. It adopts a high-resolution LCD screen. The screen surface is covered with a layer of scratch-resistant and wear-resistant tempered glass. It can not only display various measurement data clearly and accurately, but also resist scratches and collisions that occur during daily use. The power switch 4 is arranged on the outer wall of the chassis 2. The shell is made of high-quality plastic material. The internal conductive contacts are made of highly conductive metal materials to ensure stable connection and disconnection of the power supply, and have good durability and reliability. The measuring component includes a digital micrometer 6 and a load sensor 8. The outer wall of the digital micrometer 6 is slidably connected to the inside of the header fixing seat 5. The header fixing seat 5 is a circular ring that wraps the digital micrometer 6. The header fixing seat 5 is made of stainless steel. After fine processing technology, the inner surface is smooth and the size is precise. The degree is extremely high, and it can achieve a tight and smooth sliding connection with the outer wall of the digital micrometer 6, thereby providing it with an extremely stable support and guiding effect, effectively preventing the digital micrometer 6 from shaking or deflecting during operation, and providing a stable effect on the digital micrometer 6. A balancing block 7 is fixedly connected to one end of the digital micrometer 6. The balancing block 7 is made of a metal material with uniform density and is inlaid with a high-precision bearing. The bearing is made of high-quality chrome steel and has good wear resistance and rotation flexibility. When the digital micrometer 6 is rotated, it can effectively avoid driving the spring workpiece 9 to ensure the accuracy of the measurement. A spring workpiece 9 is arranged at one end of the balancing block 7, and the bottom of the load sensor 8 is fixedly connected to the top of the base 1, and one side of the load sensor 8 is arranged at the other end of the spring workpiece 9. The spring workpiece 9 is arranged between the balancing block 7 and the load sensor 8 for clamping and measurement.
[0029] Specifically, in the spring production process, the detection of the spring workpiece 9 is very important. When detection is required, the device is first conveniently moved to the production machine of the spring workpiece 9. At this time, the load display panel 3 is turned on by operating the power switch 4 and reset to zero. This step effectively avoids the interference of the residual data in the previous period on the subsequent measurement and ensures the accuracy and reliability of the data. Then, the digital micrometer 6 is rotated. The rotation of the digital micrometer 6 will drive the balancing block 7 connected thereto to move smoothly toward the outer wall of the load sensor 8. At the same time, a bearing is installed in the balancing block 7. When the digital micrometer 6 is twisted, the spring will not be driven to ensure the accuracy of the measurement. When the balancing block 7 reaches the specified position, the digital micrometer 6 is reset to zero. Subsequently, according to the requirements of the drawing, the data format on the load display panel 3 is carefully adjusted to accurately match the format required for the current measurement task, and then the load display panel 3 is reset again. After completing the above preparations, the digital micrometer 6 is reversed, and the balancing block 7 will be away from the load sensor 8, leaving enough space between the two to place the spring workpiece 9. After the spring workpiece 9 is accurately placed in the space, the digital micrometer 6 is rotated forward again, and the balance block 7 moves accordingly and applies pressure to the spring workpiece 9, so that it is gradually compressed until it reaches the specific size required for the load test. In this process, the load sensor 8 can keenly sense the pressure applied by the spring workpiece 9, and convert it into a corresponding load value and clearly display it on the load display panel 3. Through such a set of systematic and orderly operation procedures, the operator can efficiently and conveniently detect the spring workpiece 9, and obtain the load data of the spring in a timely and accurate manner, which provides a strong guarantee for the quality control of the spring, and effectively improves the work efficiency and quality reliability of the entire production and testing link. In addition, it has a simple structure, a small size, low maintenance cost and is easy to move. At the same time, the machine load display panel 3 is powered by an independent power supply, and the load display panel 3 can switch to display multiple measurement formats, and the digital micrometer 6 is also an independent power supply. During the detection, the required data can be detected simultaneously or separately, which improves the applicability.
[0030] Working principle: When inspecting the spring workpiece 9, the device is moved to the production machine of the spring workpiece 9, and then the load display panel 3 is turned on by the power switch 4, the device is reset to zero to prevent affecting the data, and then the digital micrometer 6 is rotated, and the balancing pressure block 7 is driven by the digital micrometer 6 to move to the outer wall of the load sensor 8, and the digital micrometer 6 is reset. After reset, the data format on the load display panel 3 is adjusted to the corresponding measurement format according to the requirements of the drawing, and then the load display panel 3 is reset again, and then the digital micrometer 6 is reversed to drive the balancing pressure block 7 away from the load sensor 8 to leave enough space between the two, and then the spring workpiece 9 is placed in this space, and the digital micrometer 6 is rotated forward again to drive the balancing pressure block 7 to move and compress the spring workpiece 9 to the required size for load detection, and then the load sensor 8 is subjected to the pressure of the spring workpiece 9, and then the load value of the size can be displayed, thereby conveniently inspecting the workpiece.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
