Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile production, and in particular relates to a rubber block mechanical detection device. Background Art
[0002] Automobile rubber blocks are important automobile parts. Rubber blocks are also called Baffle blocks by many OEMs. They are usually black safety accessories made of plastic. They are installed on automobile parts by snap-fitting and can be used to seal the body frame cavity structure, such as A-pillars, B-pillars, door sills, C-pillars, water troughs and other structures. Rubber blocks will expand after painting and drying, and can play a role in sealing and noise reduction. Rubber blocks are usually installed manually, and it is impossible to use the metal detection switch commonly used in automobile parts for leakage inspection. If they are manually missed, it will cause water leakage, loud noise and other quality defects in the car body, making it difficult to repair. The commonly used rubber block detection method is to use a laser photoelectric sensor to detect whether the rubber block is missed, but the cost is very high. Therefore, a low-cost rubber block mechanical detection device is proposed. Utility Model Content

[0013] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0014] The utility model provides an embodiment, please refer to Figure 1 and Figure 2 A mechanical detection device for automobile welding rubber blocks includes a base 1. The bottom of the base 1 is provided with a through hole, which can be connected to a connecting plate for easy installation. The upper part of the base 1 is provided with a through hole, which can be connected to a mounting seat 2 by bolts.
[0015] There is a high-precision through hole in the center of the mounting seat 2, so that the detection block 3 can slide in the hole. When the rubber block is not detected, the bottom of the mounting seat contacts the spring pressure block 5, acting as a limit block. A threaded hole is provided on the side of the mounting seat 2, which can be connected to the protective cover 7 to prevent welding slag from splashing into the inside of the spring 6.
[0016] See also Figure 2 and Figure 3 The detection block 3 is cylindrical as a whole. The top frustum is used to contact the rubber block. The middle and lower cylinders cooperate with the mounting seat 2 to achieve sliding. The bottom is bolted to the spring pressure block 5. The spring pressure block 5 plays the role of high-position limit and low-position detection.
[0017] The spring pressure block 5 is cylindrical as a whole, with the upper surface tightly connected to the detection block 3, and the lower surface has a groove for installing the spring 6, which is also used as a bolt countersunk head. The lower part of the spring 6 is installed in the groove of the base 2 to prevent the spring from being misplaced and causing the detection mechanism to fail.
[0018] The shield 7 is connected to the mounting base 2 by bolts to protect the internal spring 6 and the metal detection switch 4 from being affected by welding slag, thereby effectively reducing the equipment failure rate.
[0019] The metal detection switch 4 is of an integral external thread type, connected to the base 1 through a screw hole, and the tail is connected to a detection switch signal line to realize the metal detection function.
[0020] To sum up: when the automobile welding rubber block mechanical detection device is used, the base 1 is fixed to the lower part of the rubber block detection position with bolts or other tools to ensure that the installation direction of the rubber block is consistent with the sliding direction of the detection block 3. The user installs the rubber block in place, and the rubber block will press the detection block 3. The detection block 3 presses the spring pressure block 5 to the low position, triggering the metal detection switch 4 signal, which is fed back to the PLC. The PLC can determine whether the rubber block has been installed. After the operation is completed and the rubber block is taken away, the spring pressure block 5 returns to the high position under the action of the spring 6, and the metal detection switch 4 signal disappears. The device realizes the function of detecting the rubber block.
[0021] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
