Description

Technical Field

[0001] This utility model relates to a machining auxiliary device, and more particularly to an automated machining material feeding, identification and detection mechanism. Background Technology

[0002] With the rapid development of industrial automation technology, the automation level of automotive parts production on machining sites is becoming increasingly higher. During the machining process, after automated loading, it is usually necessary to identify and check whether the products have been placed correctly, such as whether tapered products are placed crookedly. Traditional identification and inspection work usually relies on manual operation, which is not only inefficient but also prone to errors due to the limitations of visual inspection. For example, if a product is missed due to worker fatigue and not replenished in time, the machining equipment will run idle, resulting in wasted resources. When checking whether a product is crooked, the naked eye is prone to misidentification or failure to detect it, resulting in significant errors. The inaccuracy of visual inspection can easily damage machine tools, thus affecting the processing quality of the product.

[0003] To ensure product quality, improve production efficiency, and prevent processing safety issues, automated material handling and detection systems are playing an increasingly important role. These systems constantly monitor the product status at each workstation during machining. If a product is not placed at a workstation or is not properly positioned, the machine tool will detect the signal from the automated material handling and detection system and trigger an alarm. However, existing automated material handling and detection systems still have limitations in their applicability to complex scenarios. In situations requiring high-precision positioning or stringent environmental adaptability, current technologies may not fully meet the needs. Therefore, researching an automated material handling and detection system that can overcome the shortcomings of existing technologies, has a simple structure, and achieves high accuracy in identification and detection is of significant practical importance. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automated feeding and identification detection mechanism for machining, which uses an air detection structure combined with spring auxiliary support to achieve accurate detection of the product placement status. It has a high detection accuracy rate, which can effectively improve production efficiency and product quality, and reduce labor costs and safety risks.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a machining automated feeding, identification, and detection mechanism, characterized in that it includes:

[0006] A base having an air detection port and a receiving cavity inside, wherein the rear end of the receiving cavity is closed and the front end is open, and the air detection port communicates with the receiving cavity;

[0007] An elastic contact block, the front end of which is used to contact the side wall of the product, is disposed on the receiving cavity;

[0008] An air detection plug is disposed in the receiving cavity, with its middle part fitting against the cavity wall of the receiving cavity, and serving as the plug body for blocking the air detection hole after the elastic contact block contacts the side wall of the product placed in place. The front part serves as a connecting part, and the rear part serves as a spring seat.

[0009] An adapter, used to connect the elastic contact block and the connecting part, is disposed within the receiving cavity;

[0010] A spring is disposed within the receiving cavity, with its front end sleeved on the spring seat and its rear end abutting against the rear end of the receiving cavity. It is used to provide elastic support. In the extended state, the plug body is offset from the air detection hole, and in the compressed state, the plug body blocks the air detection hole.

[0011] The elastic contact block is a polyurethane block. Polyurethane material has good elasticity and wear resistance. Using polyurethane blocks will not scratch the side wall surface of the product, avoiding product damage caused by the high hardness of the material.

[0012] The front end face of the elastic contact block is designed as a spherical surface. The spherical surface design reduces friction during contact, reduces wear between the front end face of the elastic contact block and the side wall of the product, not only extending the service life of the elastic contact block, but also reducing detection errors caused by wear. The spherical surface design improves the compatibility of the elastic contact block with products of different shapes. Whether the product is flat, curved, or irregularly shaped, the spherical surface can achieve good contact, expanding the application range of the testing agency.

[0013] The base has an air channel extending inward from the rear end. The axis of the air channel is parallel to the axis of the receiving cavity. The end of the air channel is connected to the air detection hole, providing a reliable detection path for the air pressure sensor.

[0014] The air channel is equipped with an air pressure sensor on the pipeline connecting to the air source to detect air pressure changes and determine whether the product has been placed or is in the correct position. By detecting air pressure changes through the air pressure sensor, real-time monitoring of the product's placement status is achieved, improving the automation and reliability of the detection process.

[0015] The diameter of the front portion of the receiving cavity is smaller than the diameter of the middle and rear portions of the receiving cavity. This design helps guide the movement of the resilient contact block and the gas detection plug, ensuring their stability and accuracy within the receiving cavity.

[0016] The elastic contact block has an inset groove extending inward from its rear end, and the adapter has an inset block at its front end. The inset block is tightly embedded in the inset groove, and the peripheral walls of the elastic contact block and the adapter are clearance-fitted with the front cavity wall of the receiving cavity. The design of the inset groove and the inset block improves the connection stability between the elastic contact block and the adapter, ensuring reliable movement; the small gap between the peripheral walls of the elastic contact block and the adapter and the front cavity wall of the receiving cavity allows for smooth movement of the elastic contact block and the adapter.

[0017] The connecting part is screwed into the inner hole of the adapter. The screwed structure improves the firmness and reliability of the connection and facilitates installation and disassembly.

[0018] The elastic contact block has a forward and backward travel distance of 1-2 mm. Limiting the travel distance ensures the stability and accuracy of the detection process and avoids detection errors caused by excessive or insufficient travel distance.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] 1) This mechanism uses the elastic support of springs to achieve the state where the main body of the gas detection plug is offset from the gas detection hole when the elastic contact block is not in contact with the product, and the state where the main body of the plug blocks the gas detection hole after the elastic contact block contacts the product. This enables the identification and detection of whether the product is placed in place. The combined use of multiple mechanisms can solve the problem of product placement identification and detection 100%, effectively improving production efficiency and product quality, and reducing labor costs and safety risks.

[0021] 2) This organization can promote the use of all tooling fixtures for the production of automotive parts on the machining site.

[0022] 3) This mechanism is suitable for occasions that require high-precision positioning or high environmental adaptability.

[0023] 4) This mechanism is ideal for identifying and detecting irregularly shaped products, such as conical products, where the front end of the elastic contact block contacts the inclined sidewall of the conical product. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] This utility model proposes an automated material feeding and identification detection mechanism for machining, as shown in the figure. It includes: a base 1, which has an air detection port 11 and a receiving cavity 12. The receiving cavity 12 is closed at its rear end and open at its front end, and the air detection port 11 communicates with the receiving cavity 12; an elastic contact block 2, whose front end is used to contact the side wall of the product, and is disposed on the receiving cavity 12; and an air detection plug 3, which is disposed inside the receiving cavity 12, with its middle part fitting against the cavity wall of the receiving cavity 12, and serves as a means for the elastic contact block 2 to contact the product when it is placed in position. The product's side wall is blocked by the plug body 31 of the air detection hole 11, the front part serves as the connecting part 32, and the rear part serves as the spring seat 33; the adapter 4 is used to connect the elastic contact block 2 and the connecting part 32, and is set in the receiving cavity 12; the spring 5 is set in the receiving cavity 12, the front end is sleeved on the spring seat 33, and the rear end abuts against the rear end of the receiving cavity 12, and is used to provide elastic support. In the extended state, the plug body 31 and the air detection hole 11 are kept offset, and in the compressed state, the plug body 31 blocks the air detection hole 11. When no product is placed on the workstation, the elastic contact block 2 remains stationary, the spring 5 is not compressed, and the plug body 31 is located in front of the air detection hole 11, without blocking the air detection hole 11. When a product is placed on the workstation but not in the correct position, the elastic contact block 2 may not contact the side wall of the product, or it may contact the side wall of the product. This is due to the different arrangement of the mechanism. Therefore, multiple mechanisms need to be arranged to identify and detect a product to ensure the accuracy of the identification and detection. When a product is placed on the workstation and in the correct position, the elastic contact block 2 contacts the side wall of the product, compresses the spring 5, causes the air detection plug 3 to retract, and the plug body 31 blocks the air detection hole 11.

[0035] As a preferred option, the elastic contact block 2 is a polyurethane block. Polyurethane material has good elasticity and wear resistance. Using polyurethane blocks will not scratch the side wall surface of the product, thus avoiding product damage caused by the high hardness of the material.

[0036] Preferably, the front end face of the elastic contact block 2 is designed as a spherical surface 21. The spherical surface 21 design reduces friction during contact, lowers wear between the front end face of the elastic contact block 2 and the side wall of the product, not only extending the service life of the elastic contact block 2 but also reducing detection errors caused by wear. The spherical surface 21 design improves the compatibility of the elastic contact block 2 with products of different shapes. Whether the product is flat, curved, or irregularly shaped, the spherical surface 21 can achieve good contact, expanding the application range of the testing mechanism.

[0037] Further, the base 1 has an air channel 13 extending inward from the rear end. The axis of the air channel 13 is parallel to the axis of the receiving cavity 12. The end of the air channel 13 is connected to the air detection hole 11, providing a reliable detection path for the air pressure sensor (not shown in the figure).

[0038] Furthermore, the pipeline connecting air channel 13 to the air source (not shown in the figure) is equipped with an air pressure sensor to detect air pressure changes and determine whether the product has been placed or is in the correct position. By detecting air pressure changes through the air pressure sensor, real-time monitoring of the product's placement status is achieved, improving the automation and reliability of the detection process.

[0039] Further specified, the diameter of the front part of the receiving cavity 12 is smaller than the diameter of the middle and rear parts of the receiving cavity 12. This design helps guide the movement of the elastic contact block 2 and the air detection plug 3, ensuring their stability and accuracy within the receiving cavity 12. The elastic contact block 2 has an embedding groove 22 extending inward from the rear end, and the front end of the adapter 4 is provided with an embedding block 41. The embedding block 41 is tightly embedded in the embedding groove 22. The peripheral walls of the elastic contact block 2 and the adapter 4 are clearance-fitted with the front cavity wall of the receiving cavity 12. The design of the embedding groove 22 and the embedding block 41 improves the connection stability between the elastic contact block 2 and the adapter 4, ensuring the reliability of the movement. There is a small gap between the peripheral walls of the elastic contact block 2 and the adapter 4 and the front cavity wall of the receiving cavity 12, so that the elastic contact block 2 and the adapter 4 can move smoothly. The connecting part 32 is screwed into the inner hole of the adapter 4. The screwed structure improves the firmness and reliability of the connection, and facilitates installation and disassembly.

[0040] Preferably, the forward and backward movement of the elastic contact block 2 is 1-2 mm. Limiting the movement ensures the stability and accuracy of the detection process and avoids detection errors caused by excessive or insufficient movement.

[0041] The mechanism is installed on a carrier within a tooling fixture. Due to its small size, it can be installed in an empty position on the carrier. Typically, four automated machining loading and inspection mechanisms are used to identify and inspect one product, located symmetrically on both sides of the product, with two mechanisms on each side. When no product is placed at the workstation, the springs 5 ​​in all four mechanisms are not compressed, and the plug body 31 does not block the air detection hole 11. When the product is not in place at the workstation, the springs 5 ​​in some mechanisms are compressed, and the plug body 31 blocks the air detection hole 11, while the springs 5 ​​in the remaining mechanisms are not compressed, and the plug body 31 does not block the air detection hole 11. When a product is placed at the workstation and in place, the springs 5 ​​in all four mechanisms are compressed, and the plug body 31 blocks the air detection hole 11 in all cases. The air pressure changes detected by the air pressure sensor differ depending on whether the plug body 31 is not blocking the air detection hole 11 or whether it is blocking the air detection hole 11, thus determining whether the product has been placed or is in place.
