Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a high-precision end cap concentricity testing tool. Background Technology

[0002] In the manufacturing process of high-precision end caps, concentricity is a key technical indicator that directly affects the assembly accuracy and performance of the product. The parts of high-precision end caps to be inspected are mostly arc-shaped structures. In traditional inspection methods, when using a measuring tape to directly measure the concentricity of the arc surface, the tape does not fit tightly against the arc surface, and the measurement reference is difficult to accurately position, easily resulting in large measurement deviations. This leads to the failure to identify defective products in a timely manner, resulting in a high rate of defective products leaving the factory and a consistently low first-pass yield.

[0003] For mass production scenarios, existing technologies often use machining with dial indicator to detect concentricity. While this method can guarantee a certain level of measurement accuracy, the operation process is cumbersome, and the inspection of a single product is time-consuming. This not only increases labor and time costs but also severely restricts the overall output efficiency of the machining production line, making it difficult to meet the actual needs of mass production for inspection efficiency and cost control.

[0004] To address the aforementioned technical challenges, there is an urgent need to develop a high-precision end cap concentricity testing tool that is compatible with arc-shaped measuring surfaces, provides accurate and efficient measurement, and is convenient and efficient. This tool would reduce measurement deviations, decrease defective product outflows, improve the first-pass yield of products, and simultaneously reduce testing costs in mass production and increase machining output.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a high-precision end cap concentricity testing tool, making it more valuable for industrial applications. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a high-precision end cap concentricity detection tool.

[0007] This utility model discloses a high-precision end cap concentricity testing tool, which includes a lower contact plate and an upper contact plate. The inner sides of the lower contact plate and the upper contact plate are arc-shaped. A connecting rod is fixed between the lower contact plate and the upper contact plate, and the lower contact plate and the upper contact plate are fixed into an integral structure by the connecting rod.

[0008] This high-precision end cap concentricity testing tool includes a lower contact plate and an upper contact plate that cooperate with each other. The inner sides of both are arc-shaped to fit the shape of the end cap. The lower contact plate and the upper contact plate are firmly connected by a connecting rod to form an integrated structure, which can quickly fit the part of the end cap to be tested to achieve convenient concentricity testing.

[0009] Furthermore, the upper end of the connecting rod has an upper adapter, and the lower part of the upper adapter is fixedly connected to the upper contact plate.

[0010] The upper adapter is mounted on the upper end of the connecting rod, and its lower part forms a firm connection with the upper contact plate, which can enhance the stability of the connection between the two and ensure the precise cooperation between the components during the testing process.

[0011] Furthermore, the lower end of the connecting rod has a lower adapter, and the lower part of the lower adapter is fixedly connected to the lower contact plate.

[0012] The lower adapter is located at the lower end of the connecting rod and is firmly connected to the lower contact plate below it. This enhances the reliability of the connection between the two, ensures the overall stability of the structure during testing, and helps to carry out accurate concentricity testing.

[0013] Furthermore, the lower adapter has an inwardly extending mounting plate that can contact the ring plate on the outer edge of the end cap.

[0014] The mounting plate extends inward from the lower adapter and can make precise contact with the ring plate on the outer edge of the end cap, playing a positioning and limiting role. This helps the testing tool quickly find the testing benchmark and improves the efficiency and accuracy of concentricity testing.

[0015] Furthermore, the number of connecting rods is at least two.

[0016] At least two connecting rods are provided to evenly distribute the force, securely connect the upper and lower contact plates, ensure the balance and reliability of the overall structure of the testing tool, and provide support for the accuracy of concentricity testing.

[0017] Furthermore, reinforcing ribs are welded between the side wall of the upper adapter and the upper contact plate.

[0018] The side wall of the upper adapter is connected to the upper contact plate by welded reinforcing ribs, which can greatly enhance the structural strength of the connection between the two, avoid deformation or loosening during the testing process, and ensure stable testing accuracy.

[0019] Furthermore, reinforcing ribs are welded between the side wall of the lower adapter and the lower contact plate.

[0020] The side wall of the lower adapter is welded with reinforcing ribs to the lower contact plate, which can significantly improve the structural stability of the connection between the two, prevent loosening of the connection during long-term use or testing under stress, and ensure the consistency and reliability of concentricity testing.

[0021] Furthermore, the surface of the connecting rod can be covered with a soft coating.

[0022] The surface of the connecting rod can be covered with a soft wrapping layer, which optimizes the hand feel, improves the comfort of holding, makes the testing process more effortless and smooth, and reduces hand fatigue after long-term use.

[0023] By means of the above-described solution, the present invention has at least the following advantages: This utility model's high-precision end cap concentricity testing tool, through its upper and lower contact plates adapted to the arc-shaped structure of the end cap and its integrated connection design, solves the problems of poor fit and inaccurate benchmark positioning in traditional tape measures, significantly reducing measurement deviation, effectively reducing the outflow of defective products, and significantly improving the first-pass yield of products.

[0024] The multi-connecting rods, combined with upper and lower adapters and reinforcing ribs, enhance the overall stability and structural strength of the tool, preventing deformation and loosening during inspection and ensuring the accuracy and consistency of concentricity testing. The extended mounting plate of the lower adapter allows for quick and accurate positioning of the inspection benchmark, simplifying the operation process. Compared to traditional machining and dial indicator testing, this significantly reduces the inspection time per unit, lowers labor and time costs, and substantially improves the output efficiency of the machining production line, making it suitable for batch production needs.

[0025] The soft-touch coating on the connecting rod surface optimizes hand comfort, reduces hand fatigue during prolonged operation, and prevents scratches and damage to the end cap surface during testing, balancing ease of operation with product protection. The overall structural design is simple, rational, and highly practical, possessing significant industrial application value.

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] See Figure 1 and Figure 2 During testing, the high-precision end cap to be tested is first placed in a suitable position. Then, holding this testing tool, the lower contact plate 1 and upper contact plate 2, with their inner arc-shaped surfaces, are aligned with the arc-shaped surface of the end cap to be tested. The integrated structure formed by the connecting rod 3 ensures that the lower contact plate 1 and upper contact plate 2 are tightly fitted to the surface of the end cap and maintain a stable relative position. Then, visual observation or auxiliary measurement methods are used to determine whether the concentricity of the end cap is qualified. This workflow does not require complicated operation steps. The arc-shaped design of the lower contact plate 1 and upper contact plate 2 can accurately adapt to the end cap structure. The integrated structure formed by the connecting rod 3 ensures the stability of the testing benchmark. This not only significantly shortens the testing time and improves the testing efficiency, but also effectively reduces the errors caused by poor fit and benchmark offset in traditional measurement methods. It significantly improves the accuracy and reliability of concentricity testing. At the same time, the integrated structure is easy to carry and operate, and is suitable for the high-efficiency testing needs of mass production scenarios.

[0031] See Figure 1 The connecting rod 3 is firmly connected to the upper contact plate 2 via the upper adapter 4 at the upper end. When the testing tool is moved by hand using the connecting rod 3, the upper adapter 4 can stably transmit the force and keep the upper contact plate 2 in a precise position, so that the upper contact plate 2 can smoothly fit the end cap to be tested. In this process, the upper adapter 4 not only realizes the reliable connection between the connecting rod 3 and the upper contact plate 2, but also ensures the fixation of their relative positions, avoiding loosening or displacement of parts during the testing process. This not only makes the operation smoother and less strenuous, but also reduces the testing deviation caused by unstable connection, further improving the accuracy and consistency of concentricity testing. At the same time, the stable connection structure also extends the service life of the tool and is suitable for the needs of long-term repeated testing.

[0032] During testing, the lower contact plate 1 is first aligned with the area to be tested below the end cap. The lower adapter 5 at the lower end of the connecting rod 3 securely connects the connecting rod 3 to the lower contact plate 1. When adjusting the position of the testing tool by holding the connecting rod 3, the lower adapter 5 firmly locks the relative position of the connecting rod 3 and the lower contact plate 1, ensuring that the lower contact plate 1 smoothly adheres to the surface of the end cap. In this workflow, the lower adapter 5 not only reliably connects the connecting rod 3 and the lower contact plate 1, but also avoids positioning deviations caused by loose component connections during testing, making the operation more convenient and efficient. At the same time, it effectively reduces testing errors caused by unstable connections, further improving the accuracy and reliability of concentricity testing, and is suitable for the needs of long-term repeated testing and mass production.

[0033] See Figure 2and Figure 3 During testing, the handheld testing tool aligns the hanging plate 6 extending inward from the lower adapter 5 with the annular plate on the outer edge of the end cap, ensuring tight contact. The contact between the hanging plate 6 and the annular plate of the end cap enables rapid positioning and limiting of the testing tool. Subsequently, maintaining the contact between the hanging plate 6 and the annular plate, the concentricity test of the end cap is completed in conjunction with the upper and lower contact plates. In this workflow, the hanging plate 6 quickly establishes the testing benchmark through precise contact with the annular plate on the outer edge of the end cap, eliminating the need for additional positioning adjustments and significantly shortening the testing preparation time. At the same time, the limiting function of the hanging plate 6 prevents the tool from shifting during the testing process, effectively reducing testing errors caused by benchmark shifts, making the operation more convenient and efficient, and further improving the accuracy and consistency of concentricity testing, thus adapting to the rapid testing needs in mass production scenarios.

[0034] During testing, the testing tool is operated by holding at least two connecting rods 3, ensuring that the lower contact plate 1 and the upper contact plate 2 are precisely aligned with the end cap to be tested and stably fitted together. Multiple connecting rods 3 are evenly distributed between the upper and lower contact plates, synchronously transmitting force and providing stable support for the overall structure. This ensures that the upper and lower contact plates and the end cap surface remain tightly fitted and their relative positions remain unchanged throughout the testing process. In this workflow, the design of at least two connecting rods 3 can evenly distribute the force, avoiding structural deformation or positioning deviation caused by excessive force on a single connecting rod. This makes the operation more effortless and smooth, while significantly improving the overall stability and balance of the testing tool. It effectively reduces testing errors caused by structural instability, further ensuring the accuracy and consistency of concentricity testing, and is suitable for the high-frequency and high-efficiency testing needs in mass production.

[0035] During testing, the upper adapter 4 and the upper contact plate 2 are pre-connected, and the structural connection is strengthened by the reinforcing ribs welded between them. The handheld tool is adjusted to make the upper contact plate 2 fit against the end cap to be tested. During the testing process, the reinforcing ribs continuously stabilize the relative position of the upper adapter 4 and the upper contact plate 2, preventing the connection from loosening or deforming due to force. In this workflow, the reinforcing ribs directly improve the connection strength between the upper adapter 4 and the upper contact plate 2, eliminating the need for additional reinforcement operations, making the testing operation smoother and more efficient. At the same time, it effectively avoids the testing deviation caused by unstable component connections, ensuring the accuracy and consistency of concentricity testing, extending the service life of the tool, and adapting to long-term, high-frequency testing needs.

[0036] During testing, the connection between the lower adapter 5 and the lower contact plate 1 is reinforced by a reinforcing rib welded between them. The handheld tool aligns the lower contact plate 1 with the end cap to be tested and attaches it. During the testing process, the reinforcing rib continuously bears the force, firmly locking the relative position of the lower adapter 5 and the lower contact plate 1, preventing loosening of the connection or structural deformation. In this workflow, the reinforcing rib significantly improves the connection stability and structural rigidity of the lower adapter 5 and the lower contact plate 1, eliminating the need for additional adjustments and reinforcements, making the testing operation more convenient and smooth. At the same time, it effectively reduces the testing deviation caused by unstable component connections, ensuring the accuracy and consistency of concentricity testing, extending the service life of the tool, and adapting to the needs of long-term, high-frequency, repeated testing.

[0037] During testing, the testing tool is operated by holding the soft covering layer on the surface of the connecting rod 3. The position is adjusted so that the tool fits against the end cap to be tested to complete the concentricity test. Throughout the process, the soft covering layer fits tightly against the hand and increases grip friction. In this workflow, the soft covering layer not only improves the comfort of holding the connecting rod 3 and avoids hand fatigue from prolonged operation, but also prevents the tool from slipping during gripping, making the testing operation more stable and smooth. At the same time, the soft material will not damage the surface of the connecting rod 3, and can also reduce friction wear between the hand and the connecting rod 3, extending the tool's service life and adapting to long-term, high-frequency testing needs.
