Description

Technical Field

[0001] This utility model relates to a hole error prevention sensing device that is not easily damaged by welding heat. Background Technology

[0002] Existing error-proofing devices for fixtures mainly consist of fixed pins (hard error-proofing) and laser sensors (soft error-proofing). Due to the product's unique structure, the error-proofing holes are all located on the side, and the error-proofing space is relatively small. Traditional fixed pins, which offer good error-proofing and are unaffected by welding heat, are mostly used for bottom hole error-proofing. However, their limited mobility hinders normal part handling, making them unsuitable for fixed pin error-proofing. Early laser error-proofing sensors and spring-loaded telescopic pin sensors, limited by space and close to the weld bead, are easily affected by welding heat, causing laser emission to become insensitive and malfunctioning, or by weld spatter causing spring return failure. Furthermore, due to the product's unique structure, defective parts installed incorrectly due to error-proofing failure cannot be repaired and must be scrapped. Therefore, an effective and durable error-proofing device is crucial for this fixture.

[0003] In order to solve the above problems, this utility model is hereby proposed. Utility Model Content

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-2As shown, a hole-prevention sensing device that is not easily damaged by welding heat includes cylinder 4, cylinder 5, and cylinder 6. Cylinder 4, cylinder 5, and cylinder 6 are located on the welding positioning plate 8 and are used to prevent the front cabin assembly bracket 1, front cabin assembly bracket 2, and front cabin assembly bracket 3 from being mispositioned. The front cabin assembly bracket 1, front cabin assembly bracket 2, and front cabin assembly bracket 3 are welded together to form the front cabin assembly bracket assembly. For the purpose of preventing mispositioning, the inner side of the front cabin assembly bracket 1 has an inwardly facing elongated hole 7, the outer side of the front cabin assembly bracket 2 has a straight hole, and the inner side of the front cabin assembly bracket 3 has an oblique hole. The position of cylinder 4 corresponds to the position of the elongated hole 7 of the front cabin assembly bracket 1, the position of cylinder 5 corresponds to the position of the straight hole of the front cabin assembly bracket 2, and the position of cylinder 6 corresponds to the position of the oblique hole of the front cabin assembly bracket 3.

[0020] A telescopic plate 1 is provided on the telescopic shaft of cylinder 4, a telescopic plate 2 is provided on the telescopic shaft of cylinder 5, and a telescopic plate 3 is provided on the telescopic shaft of cylinder 6. An anti-misalignment pin 1 is provided on the telescopic plate 1, an anti-misalignment pin 2 is provided on the telescopic plate 2, and an anti-misalignment pin 3 is provided on the telescopic plate 3.

[0021] Cylinder 4 is equipped with stroke sensor 1, which is used to sense the extension distance 1 of telescopic plate 1. Cylinder 5 is equipped with stroke sensor 2, which is used to sense the extension distance 2 of telescopic plate 2. Cylinder 6 is equipped with stroke sensor 3, which is used to sense the extension distance 3 of telescopic plate 3.

[0022] The shape of the anti-misalignment pin 1 corresponds to the elongated hole 7 of the front cabin assembly bracket 1. The telescopic shaft of the cylinder 4 extends and retracts, driving the anti-misalignment pin 1 to move. When the front cabin assembly bracket 1 is in the correct position, the elongated hole 7 accommodates the anti-misalignment pin 1. At this time, the extension distance 1 of the telescopic plate 1 can be sensed by the stroke sensor 1. By comparing the extension distance 1 with the standard distance, it is determined whether the elongated hole 7 accommodates the anti-misalignment pin 1.

[0023] The shape of the second anti-misalignment pin corresponds to the positive hole of the second front cabin assembly bracket 2. The telescopic shaft of the second cylinder 4 extends and retracts, driving the second anti-misalignment pin to move. When the position of the second front cabin assembly bracket 2 is correct, the positive hole accommodates the second anti-misalignment pin. At this time, the extension distance of the second telescopic plate can be sensed by the second stroke sensor. By comparing the extension distance with the standard distance, it is determined whether the positive hole accommodates the second anti-misalignment pin.

[0024] The shape of the anti-misalignment pin three corresponds to the oblique hole of the front cabin assembly bracket three 3. The telescopic shaft of the cylinder three 4 extends and retracts, driving the anti-misalignment pin three to move. When the position of the front cabin assembly bracket three 3 is correct, the oblique hole accommodates the anti-misalignment pin three. At this time, the extension distance three of the telescopic plate three can be sensed by the stroke sensor three. By comparing the extension distance three with the standard distance, it is determined whether the oblique hole accommodates the anti-misalignment pin three.

[0025] This invention places an anti-misalignment pin on a cylinder, using the cylinder to push and drive the anti-misalignment pin to detect product errors. Simultaneously, a stroke sensor is installed on the cylinder to determine whether the product is installed backwards or incorrectly based on whether the cylinder stroke is complete. The cylinder-driven anti-misalignment pin mechanism allows for flexible movement of the anti-misalignment device, avoiding interference with the product handling process. This movable anti-misalignment sensing device solves the problems of existing fixed hard anti-misalignment devices, which lack flexibility, and where laser sensors and spring extension sensors are easily damaged by welding heat due to their proximity to the weld bead.

[0026] This invention utilizes a cylinder-driven anti-error pin to achieve product error prevention detection. Because cylinders are more heat-resistant than laser sensors, they can effectively adapt to harsh high-temperature welding environments. Furthermore, the cylinder, driven by air pressure, can output a large pushing force, and ordinary weld spatter has little impact on it, effectively extending the service life of the error prevention device. Simultaneously, the cylinder-driven anti-error pin design enables error prevention detection during welding; after welding is complete, the cylinder drives the anti-error pin to retract, avoiding interference with part handling and making the fixture operation more flexible and efficient.

[0027] This invention aims to ensure product quality by providing a fault-prevention device that can effectively identify incorrect or reversed parts, is unaffected by welding heat, and has a long service life, while ensuring sufficient operating space for the welding torch and easy handling of parts before and after welding.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
