Description

Technical Field

[0001] This utility model belongs to the field of testing machine technology, and specifically relates to a multi-segment flexible testing machine contact. Background Technology

[0002] In industrial production, the inspection process is crucial, as it relates to product quality control and production process optimization. As a key component of inspection equipment, the inspection machine contact head directly contacts the product being inspected, and its performance directly affects the accuracy and reliability of the inspection results. The main function of the inspection machine contact head is to acquire physical characteristic information about the product being inspected, such as the surface smoothness, roughness, and presence of defects. Through this information, manufacturers can promptly identify problems in the production process, thereby taking corresponding measures to ensure product quality, reduce defect rates, and improve production efficiency.

[0003] Traditional inspection probes have revealed numerous drawbacks in practical applications. From a material perspective, traditional probes are mostly made of hard materials, such as metal. While metals possess a certain strength and wear resistance, their flexibility is extremely poor. This results in the probes failing to fit tightly against the surface of complex curved products. For example, when inspecting plastic products or precision molds with irregular curved surfaces, gaps exist between the hard probe and the product surface, making it impossible to comprehensively and accurately detect all parts of the product surface, easily missing surface defects, and thus affecting the accuracy of product quality inspection. In terms of structural design, traditional inspection probes have a relatively simple and fixed structure. Adjacent components are usually rigidly connected, lacking adjustable and flexible designs. This makes the probes extremely unsuitable for products of different shapes and sizes. For instance, when the size of the product to be inspected changes, or the product shape changes from flat to curved, traditional inspection probes cannot flexibly adjust their structure to adapt to the inspection needs of the new product. Companies must replace the entire inspection probe or even the entire inspection equipment, which undoubtedly increases production and time costs. Moreover, during long-term use, traditional detection contacts are prone to loosening and wear in rigid connection parts due to external impacts and friction. This not only reduces the service life of the detection contacts but also affects the detection accuracy, leading to deviations in the detection results. Utility Model Content

[0004] In view of this, the present invention provides a multi-segment flexible testing machine contact, which solves the problem of the traditional testing machine contact having a single structure and poor adaptability, and improves the testing accuracy and adaptability.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a multi-segment flexible testing machine contact, which includes: a testing contact body, wherein the testing contact body is composed of multiple bendable flexible segments connected in sequence;

[0007] A fixed base is used to fix the detection contact body;

[0008] A connecting component is used to connect the detection contact body and the fixed base; the flexible segment is a cylindrical structure, and adjacent flexible segments are connected by a flexible connecting part, which is a thin sheet structure made of flexible material, and both ends of the flexible connecting part are fixedly connected to the adjacent flexible segments respectively.

[0009] The flexible segment is cylindrical in shape, with each segment having the same diameter. Multiple flexible segments are arranged sequentially along the axial direction, with the central axes of adjacent flexible segments coinciding and connected by flexible connectors.

[0010] Based on the above technical solution, the multi-segment flexible testing machine contact of this utility model can be further improved as follows:

[0011] The fixing base is a block structure and has a mounting groove for installing the connecting component.

[0012] Furthermore, the connecting assembly includes a connecting rod and a connecting sleeve. One end of the connecting rod is fixedly connected to the detection contact body, and the other end is inserted into the connecting sleeve. The connecting sleeve is fixedly connected to the fixed base.

[0013] Furthermore, the connecting rod and the connecting sleeve are connected by a thread.

[0014] Furthermore, the flexible segment is provided with a wire for transmitting detection signals, and the wires between adjacent flexible segments are connected by a conductive connector.

[0015] Furthermore, the fixed base is provided with mounting holes for connecting to external devices.

[0016] Furthermore, the flexible segment is made of silicone.

[0017] Furthermore, the bending angle between the flexible segments of the detection contact body ranges from 0 to 90 degrees.

[0018] The flexible segment is made of silicone material with specific flexibility and elasticity. The Shore hardness of the silicone material is between 30-50HA, which ensures that the flexible segment can bend and deform when subjected to a certain external force, and can return to its original shape after the external force is removed, thus providing a material basis for achieving bending angles of 0-90 degrees.

[0019] A limiting structure is provided inside the flexible segment near the flexible connection. The limiting structure is an arc-shaped protrusion or groove. When the bending angle between the flexible segments reaches 90 degrees, the limiting structures on the adjacent flexible segments contact each other, preventing the flexible segments from bending further, thereby limiting the maximum bending angle to 90 degrees and ensuring that the detection contact will not be damaged due to excessive bending during normal use.

[0020] Furthermore, the fixed base and the central axis of the detection contact body are on the same straight line.

[0021] Furthermore, the foremost flexible segment of the detection contact body is provided with a detection sensing element, which is embedded in the front surface of the foremost flexible segment.

[0022] The detection sensing element is an optical sensor, which detects physical characteristics such as defects, flatness, and roughness on the product surface by emitting and receiving light and based on the reflection, refraction, or scattering of the light.

[0023] For example, the optical sensor is a laser displacement sensor. By emitting a laser beam onto the product surface and measuring the time or phase difference of the reflected light return, the distance between the detection contact and the product surface can be accurately calculated, thereby achieving high-precision detection of the product surface contour and size. The laser displacement sensor is embedded in the front surface of the most front flexible segment.

[0024] Compared with the prior art, the beneficial effects of the multi-segment flexible testing machine contact provided by this utility model are:

[0025] Improved fit and enhanced detection accuracy: This invention employs a multi-segment flexible detection probe, with each segment made of silicone material, possessing excellent flexibility and elasticity. When inspecting complex curved surface products, the probe can freely bend according to the product's surface shape, closely fitting every detail of the product surface. Taking the inspection of the complex curved inner wall of an automobile engine cylinder block as an example, traditional rigid probes cannot fully cover the inner wall surface, while the flexible detection probe of this invention can easily bend into the cylinder block, closely fitting the inner wall. This allows for precise detection of minute cracks, pinholes, and other defects on the inner wall surface, greatly improving detection accuracy and effectively avoiding product quality problems caused by missed inspections.

[0026] Enhanced adaptability and expanded application range: The flexible segments are connected by flexible connectors of specific dimensions, making the overall structure of the detection contact adjustable and flexible. This design allows the detection contact to adapt to the inspection needs of products with various shapes and sizes. Whether it is a planar product, a curved product, or a product with a special shape, the detection contact of this invention can achieve effective inspection through adjustments to its own structure. For example, in the electronics manufacturing industry, traditional detection contacts often need to be frequently replaced for products such as circuit boards and chips of different sizes and shapes. However, the detection contact of this invention can be flexibly adjusted according to the specific shape and size of the product without changing equipment, greatly improving inspection efficiency, reducing production costs, and expanding the application range of the inspection equipment.

[0035] The connecting component 30 is used to connect the detection contact body 10 and the fixed base 20; the flexible segment 21 is a cylindrical structure, and adjacent flexible segments 21 are connected by a flexible connecting part 22. The flexible connecting part 22 is a thin sheet structure made of flexible material, and both ends of the flexible connecting part 22 are fixedly connected to the adjacent flexible segments 21 respectively.

[0036] In the above technical solution, the fixed base 20 is a block structure and has a mounting groove for installing the connecting component 30.

[0037] Furthermore, in the above technical solution, the connecting component 30 includes a connecting rod and a connecting sleeve.

The connecting sleeve is fixedly connected to the fixed base 20.

[0038] The connecting assembly includes a connecting rod and a connecting sleeve. The connecting rod is cylindrical, with one end fixedly connected to the center of the flexible section of the detection contact body closest to the fixed base. The connection method is embedded bonding to ensure a firm connection. The connecting sleeve is a hollow cylinder with an inner diameter matching the outer diameter of the connecting rod and an outer diameter matching the inner diameter of the mounting groove on the fixed base. It is fitted onto the connecting rod and fixed to the fixed base via an interference fit or threaded connection, located between the fixed base and the detection contact body to achieve the connection between the two.

[0039] Furthermore, in the above technical solution, the connecting rod and the connecting sleeve are connected by a thread.

[0040] Furthermore, in the above technical solution, the flexible segment 21 is provided with a wire for transmitting detection signals, and the wires between adjacent flexible segments 21 are connected by a conductive connector.

[0041] Furthermore, in the above technical solution, the fixed base 20 is provided with mounting holes for connecting to external equipment.

[0042] Furthermore, in the above technical solution, the flexible segment 21 is made of silicone.

[0043] Furthermore, in the above technical solution, the bending angle range between the flexible segments 21 of the detection contact body 10 is 0-90 degrees.

[0044] Furthermore, in the above technical solution, the central axis of the fixed base 20 and the detection contact body 10 are on the same straight line.

[0045] Furthermore, in the above technical solution, the foremost flexible segment 21 of the detection contact body 10 is provided with a detection sensing element, which is embedded in the front surface of the foremost flexible segment 21.

[0046] Specifically, the principle of this utility model is as follows:

[0047] Material Principle: The flexible segment of this invention is made of silicone. Silicone is a high-molecular-weight elastic material with excellent flexibility, elasticity, and chemical stability. Its flexibility allows the flexible segment to bend and deform under external force, thus adapting to the testing needs of products with different shapes. When the testing contact comes into contact with the product surface, the flexible segment of silicone can bend according to the undulations of the product surface to achieve a tight fit. At the same time, the elasticity of silicone ensures that the flexible segment can return to its original shape after the external force is removed, and will not undergo plastic deformation due to long-term bending, ensuring the long-term stable use of the testing contact. In addition, the chemical stability of silicone allows it to maintain stable performance in various complex testing environments, is not easily corroded by chemical substances, and extends the service life of the testing contact.

[0048] Structural Principle: The core structural principle of this invention is a multi-segment structure. Multiple flexible segments are sequentially connected by flexible connectors to form the main body of the detection contact. The flexible connectors adopt a flexible sheet-like structure with a thickness between 0.5-1.5 mm and a width between 5-10 mm. This dimensional design ensures that the flexible connectors have sufficient strength to guarantee a stable connection between adjacent flexible segments, while also possessing good flexibility, allowing them to deform accordingly when the flexible segments bend, thus achieving overall bendability of the detection contact. When the detection contact needs to inspect products with complex curved surfaces, the flexible connectors can bend along with the flexible segments, allowing the detection contact to flexibly adapt to changes in the shape of the product surface. For example, when inspecting products with multiple surfaces of different curvatures, the different flexible segments of the detection contact can adjust their bending angles through the deformation of the flexible connectors, achieving comprehensive inspection of the entire product surface.
