Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts, in particular to a profile height detection mechanism. Background Art

[0002] A research report by the World Energy Conservation and Environment Association pointed out that if the weight of the whole vehicle is reduced by 10%, the fuel efficiency can be improved by 6% to 8%. In the face of the rising number of domestic cars, increasing emissions, increasingly serious environmental pollution, global resource shortages, and insufficient endurance of new energy vehicles, lightweight cars will be one of the important development directions of future cars. Comprehensively comparing lightweight materials such as aluminum alloys, titanium alloys, magnesium alloys, and non-metallic carbon fiber composites, high-strength steel is currently one of the best materials to meet the lightweight requirements of the car body and improve collision safety performance. In recent years, hot forming has been more and more widely used in OEMs. Since hot forming parts involve very complex metal material heat, force, phase change and other multi-physical field coupling and other problems, hot forming parts have many special requirements in quality control compared to cold stamping parts. In this context, the process control technology of hot forming will be a topic jointly studied by OEMs and hot forming suppliers and will be continuously updated.

[0003] During the hot pressing process, the material flows unevenly in the mold, and the product shape changes with the changes in the angle position of the sheet input, the initial contact position, the stamping speed (strain speed), the stamping deformation pressure, the mold temperature and the ambient temperature, etc. All parts have fluctuations. Different parts produce different fluctuations according to the shape of the parts. Different degrees of shape fluctuations have a serious impact on the downstream laser cutting and customer assembly. Therefore, it is necessary to effectively detect the hot-formed parts in the ultra-fluctuation range. However, in traditional detection methods, the existing technology requires manual operation or adjustment, which increases the labor intensity and the possibility of error. Some detection mechanisms may have complex structures and high costs, which are not conducive to large-scale applications. Summary of the invention

[0004] In view of this, the utility model aims to propose a surface height detection mechanism, which can effectively detect hot-formed parts beyond the fluctuation range and reduce the cost of personnel inspection.

[0007] The guide rail is arranged on the left side of the mechanism fixing block, the insulating device and the spring mounting block are installed on the front side of the mechanism fixing block, and the metal U-shaped block is installed on the insulating device;

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] The present embodiment relates to a mold surface height detection mechanism, which can effectively detect hot-formed parts beyond the fluctuation range and reduce the cost of personnel inspection.

[0023] Based on the above design concept, an exemplary structure of the profile height detection mechanism of this embodiment is as follows: Figure 1-3 As shown, it mainly includes a relay, the relay is connected with a hub, a sensor and a detection part, the hub and the sensor are connected by a signal line, and the detection part includes a detection pin 1, a spring mounting block 2, a guide rail 3, a mechanism fixing block 4, an insulating device 5, a metal U-shaped block 6, a detection block 7, a multi-accessory mounting block 8, a detection block mounting block 9, a slider 10, a spring 11 and a bolt 12; a guide rail 3 is provided on the left side of the mechanism fixing block 4, an insulating device 5 and a spring mounting block 2 are installed on the front of the mechanism fixing block 4, and a metal U-shaped block 6 is installed on the insulating device 5; a slider 10 is slidably installed on the guide rail 3, the slider 10 is fixedly installed on the detection block mounting block 9, a detection block 7 is installed on the lower end surface of the detection block mounting block 9, and the right side of the detection block 7 is located in the metal U-shaped block 6; a multi-accessory mounting block 8 is installed on the lower end surface of the left side of the detection block 7, and a detection pin 1 is installed on the left side of the upper end surface of the multi-accessory mounting block 8; bolts 12 are provided on the spring mounting block 2 and the multi-accessory mounting block 8, and the two ends of the spring 11 are respectively hung on two bolts 12.

[0024] Based on the foregoing, when the detection block 7 is not in contact with the metal U-shaped block 6, the sensor is always on, and the device receives the sensor feedback signal and operates normally; when the detection block 7 is in contact with the metal U-shaped block 6, the sensor is not on, and the device does not receive the sensor feedback signal and cannot operate, that is, the connection between the signal sensor and the relay, and the control of the relay by the detection unit must meet the purpose of the signal sensor normally feeding back signals to the device when the parts are qualified, and the signal sensor terminating the feedback signal to the device when the parts are unqualified.

[0025] When the profile height detection mechanism described in this embodiment is used, Figure 2 As shown, it is installed below the position where the part needs to be inspected. The up and down moving distance of the detection block 7 in the metal U-shaped block 6 is the range of fluctuation of the qualified part profile. The part is pressed on the detection pin 1. At this time, if the profile of the part in this area is within the qualified range, the detection block 7 is in a suspended state, the feedback signal sensor is always on, and the equipment operates normally. Otherwise, the detection block 7 contacts the metal U-shaped block 6, the feedback signal sensor is off, and the equipment cannot operate normally, so as to screen out unqualified parts.

[0026] The surface height detection mechanism adopted in the above-mentioned implementation scheme has effectively solved the shortcomings of the traditional detection method. By combining with the laser cutting tooling, it can effectively detect hot-formed parts beyond the fluctuation range, thereby reducing the cost of personnel inspection. The principle is to use the detection part limit component according to the fluctuation range that can be released by the part surface. When the part surface exceeds the specified range, the detection block 7 reaches the limit position, that is, the detection block 7 contacts the metal U-shaped block 6, and then triggers the sensor detection signal interruption, and the equipment cannot run.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
