Description

Technical Field

[0002] Plug gauges, as a common precision inspection tool, are widely used in mechanical manufacturing, assembly, and quality inspection to check the dimensions and fit clearances of workpieces. However, traditional plug gauge operation relies on manual operation, resulting in low efficiency and accuracy easily affected by the operation. Therefore, how to quickly and accurately position and clamp plug gauges has become an important issue for improving production efficiency and inspection accuracy. Designing rapid positioning and clamping devices for plug gauges faces challenges in terms of accuracy, stability, ease of operation, and adaptability. Modern technologies, such as pneumatic clamping devices, electric clamping devices, and the application of robotic arms, have greatly improved the efficiency and accuracy of clamping and positioning. In the future, with the development of intelligent control, automation technology, and digital management, rapid positioning and clamping devices for plug gauges will become more intelligent and precise, integrating more functions to provide more efficient and reliable solutions for precision manufacturing and automated production.

[0003] However, in practical use, existing solutions lack autonomous positioning, potentially leading to deviations in plug gauge placement and inaccurate dimensional inspection results. This affects workpiece quality inspection, potentially resulting in defective parts entering the production line or reaching customers, impacting overall product quality. Furthermore, relying on manual or semi-automated positioning methods introduces human error. Even experienced operators cannot guarantee consistently high precision in every operation, which can lead to long-term fluctuations in product quality.

[0004] Therefore, this utility model provides a quick positioning and clamping device for plug gauges. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies cannot perform autonomous positioning, and the placement of plug gauges may be deviated, leading to inaccurate dimensional inspection results. This affects the quality inspection of workpieces, potentially causing unqualified parts to enter the production line or to customers, thus impacting the overall product quality. Therefore, this invention proposes a quick positioning and clamping device for plug gauges.

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

[0007] A plug gauge quick positioning and clamping device includes a base plate, a clamping assembly on the outer side of the base plate, a plurality of clamping arms on the clamping end of the clamping assembly, one end of each clamping arm being rotatably connected to the base plate, uniformly distributed limiting posts fixedly connected to the top wall of the base plate, a protective ring fixedly connected to the outer side of the middle section of each limiting post, a transmission assembly on the inner side of each limiting post, a positioning slider on the moving end of the transmission assembly, a limiting component on the outer side of the top section of each limiting post, and a slide rail on the limiting end of the limiting component, the slide rail being slidably connected to the positioning slider.

[0008] As a preferred technical solution of this application, the transmission component includes a spring, one end of which is fixedly connected to the base plate, and the other end of which is fixedly connected to a transmission sleeve. A uniformly distributed hinge is fixedly connected to the outside of the transmission sleeve, and the other end of the hinge is fixedly connected to a positioning slider.

[0009] As a preferred technical solution of this application, the limiting component includes a limiting frame, which is fixedly connected to a limiting post. The limiting frame has sliding grooves on both sides, which are slidably connected to a hinge. The limiting frame is fixedly connected to a slide rail.

A uniformly distributed pneumatic rod is rotatably connected to the outside of the support rod, and the telescopic end of the pneumatic rod is rotatably connected to the middle section of the clamping arm.

[0012] As a preferred technical solution of this application, the inner wall of the positioning slider and the clamping end of the clamping arm are both provided with a rubber layer.

[0013] Compared with the prior art, this utility model provides a quick positioning and clamping device for plug gauges, which has the following advantages:

[0014] 1. The plug gauge quick positioning and clamping device of this utility model, after the plug gauge is placed on the spring, the plug gauge's own weight will press down on the transmission sleeve, compressing the spring. Simultaneously, the transmission sleeve, via a hinge, drives the positioning slider to move in the middle, thereby automatically positioning the plug gauge.

It increases work efficiency, reduces operation time, decreases rework and quality fluctuations, lightens the burden on operators, and reduces the risk of accidents. Furthermore, the automated system supports intelligent production, improves overall efficiency, and ensures stability through real-time monitoring and adjustment, reducing labor and time costs and optimizing the production line.

[0015] 2. The plug gauge quick positioning and clamping device of this utility model drives the clamping arm to rotate around the connection point between the clamping arm and the base plate through the telescopic ends of multiple air rods, thereby quickly clamping the plug gauge. At the same time, by using different telescopic lengths of different air rods, the clamping center point can be adjusted, which improves the flexibility and personalization of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0023] Reference Figure 1-4A quick positioning and clamping device for plug gauges includes a base plate 1. A clamping assembly is provided on the outer side of the base plate 1, providing stress points for the clamping assembly. The clamping end of the clamping assembly is provided with multiple clamping arms 13, one end of which is rotatably connected to the base plate 1. The base plate 1 limits the clamping arms 13. Uniformly distributed limiting posts 2 are fixedly connected to the top wall of the base plate 1, supporting and fixing the limiting posts 2. A protective ring 21 is fixedly connected to the outer side of the middle section of the limiting post 2, supporting and fixing the protective ring 21 and protecting the internal structure of the device. A transmission assembly is provided on the inner side of the limiting post 2, and a positioning slider 22 is provided on the moving end of the transmission assembly. A limiting component is provided on the outer side of the top section of the limiting post 2, and a slide rail 31 is provided on the limiting end of the limiting component. The slide rail 31 is slidably connected to the positioning slider 22, limiting the positioning slider 22 and allowing the positioning slider 22 to slide outside the slide rail 31.

[0024] The transmission assembly includes a spring 23. One end of the spring 23 is fixedly connected to the base plate 1, and the base plate 1 fixes the bottom end of the spring 23. The other end of the spring 23 is fixedly connected to a transmission sleeve 24, and the spring 23 pushes the transmission sleeve 24 away from the base plate 1 with the base plate 1 as the stress point. The outer side of the transmission sleeve 24 is fixedly connected to evenly distributed hinges 25, and the transmission sleeve 24 fixes the hinges 25. The other end of the hinges 25 is fixedly connected to the positioning slider 22, and the hinges 25 connect the transmission sleeve 24 and the positioning slider 22. Thus, the lifting and lowering of the transmission sleeve 24 is driven by the hinges 25 to move the positioning slider 22, while the positioning slider 22 moves in the opposite direction.

[0025] The limiting component includes a limiting frame 3, which is fixedly connected to a limiting post 2. The limiting frame 3 is fixed by the limiting post 2. The limiting frame 3 has sliding grooves 32 on both sides, which are slidably connected to a hinge 25. The hinge 25 is limited by the corresponding sliding grooves 32 on the outside of the limiting frame 3, so that the moving end of the hinge 25 can slide in the sliding grooves 32. The limiting frame 3 is fixedly connected to a slide rail 31, which is fixed by the limiting frame 3.

[0026] The clamping assembly includes a support rod 11, which is fixedly connected to a base plate 1. The base plate 1 supports and fixes the support rod 11. A uniformly distributed pneumatic rod 12 is rotatably connected to the outside of the support rod 11. The support rod 11 limits the movement of the pneumatic rod 12. The telescopic end of the pneumatic rod 12 is rotatably connected to the middle section of the clamping arm 13. The pneumatic rod 12 limits the movement of the middle section of the clamping arm 13. At the same time, the pneumatic rod 12 pushes the clamping arm 13 outward with the support rod 11 as the stress point. The base plate 1 connects to one end of the clamping arm 13, thereby causing the clamping arm 13 to rotate around the connection point between the clamping arm 13 and the base plate 1.

[0027] The clamping arm 13 and the positioning slider 22 are arranged alternately around the transmission sleeve 24. A plug gauge 4 is provided on the inner side of the clamping arm 13. The plug gauge 4 is engaged with the clamping arm 13 and slidably connected to the positioning slider 22. The plug gauge 4 is positioned by the opposing movement of the positioning slider 22. At the same time, the clamping arm 13 rotates to clamp and fix the plug gauge 4.

[0028] The inner wall of the positioning slider 22 and the clamping end of the clamping arm 13 are both provided with rubber layers. By providing rubber layers on the outer walls of the positioning slider 22 and the clamping arm 13, the plug gauge 4 can be limited and clamped, thereby buffering the positioning slider 22 and the clamping arm 13 with the plug gauge 4 and avoiding damage to the surface of the plug gauge 4.

[0029] Specifically, when using this plug gauge quick positioning and clamping device: First, place the plug gauge 4 on the transmission sleeve 24. Then, the plug gauge 4 presses down on the transmission sleeve 24 by its own weight. At the same time, the transmission sleeve 24 squeezes the spring 23 and moves it downward. The downward movement of the transmission sleeve 24 drives one end of the hinge 25 to move synchronously. Thus, the hinge 25 drives the positioning slider 22 to move inward from the outside of the slide rail 31, adjusting the position of the plug gauge 4 and completing the positioning. Then, multiple air rods 12 push the bottom end of the clamping arm 13 outward with the support rod 11 as the stress point, thereby causing the clamping arm 13 to rotate around the connection point between the clamping arm 13 and the base plate 1. The clamping arm 13 clamps and fixes the plug gauge 4.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
