Description

AB hybrid sealant lengthened rubber head correction device Technical Field The utility model relates to the technical field of steering systems, in particular to an AB mixed sealant lengthened rubber head correction device. Background In the manufacturing process of an automobile steering machine, the coating quality of the sealant is important for the sealing performance of the steering machine. When producing steering engine SCU part, because of dodging SCU socket and selecting a plastics material spiral to mix the extension rubber tube, this rubber tube needs periodic replacement, when changing, because of plastic products deformation reason, lead to unable location, the offset of position is great, the coating track that appears at the coating in-process of sealant is partial or the rubber head collides with the product, influence the sealed effect of car steering engine, increased the risk that appears quality problems such as seepage, and current correction method operation is complicated, inefficiency, can't satisfy the high-efficient production demand of steering engine SCU manufacturing. Disclosure of Invention The utility model provides the AB mixed sealant lengthened rubber head correction device for overcoming the defects in the prior art, staff can quickly and accurately find a rubber needle datum point after replacing a plastic spiral mixed rubber tube through the matching of the correction device and a control system, and the sensor is used for detecting the position deviation and correcting in time, so that the coating quality of sealant is ensured, and the sealing performance of an automobile steering gear is improved. In order to achieve the aim, the AB mixed sealant lengthened rubber head correction device is designed and comprises a connecting plate, a positioning block and a rubber needle positioning sleeve, and is characterized in that the connecting plate comprises a main connecting plate and an auxiliary connecting plate, the positioning block comprises a long positioning block and a short positioning block, the long positioning block and the short positioning block are respectively connected to the main connecting plate, the lower part of the main connecting plate is connected with the auxiliary connecting plate through a rubber needle positioning cylinder mounting bracket, a plastic spiral mixed rubber tube guide sleeve is arranged on the rear side of the rubber needle positioning cylinder mounting bracket, a rubber needle is connected to the bottom of the plastic spiral mixed rubber tube guide sleeve, and the rubber needle positioning sleeve is sleeved on the outer side of the joint of the plastic spiral mixed rubber tube guide sleeve and the rubber needle. The long positioning block is of a strip-shaped rectangular module structure and is positioned at the front end of the top of the main connecting plate.
