Universal locating and tensioning try for seat frame assembling

Abstract

The invention relates to a universal locating and tensioning tray for seat frame assembling. A seat frame comprises a frame body and two sliding rails arranged on the left and right sides of the lowerend of the frame body. The two sliding rails are provided with first mounting holes and second mounting holes correspondingly. The universal locating and tensioning tray for seat frame assembling ischaracterized in that the universal locating and tensioning tray comprises a tray base and two fixing devices arranged on the left and right sides of the tray base correspondingly, the fixing devicesare used for fixing the corresponding sliding rails, and one of the fixing devices can move left and right. Each fixing device comprises a mounting base, a locating mechanism, a tensioning mechanism and a clamping mechanism, wherein the tensioning mechanism, the locating mechanism and the clamping mechanism are sequentially arranged on the mounting base from front to back and can move front and back on the mounting base; the locating mechanisms are provided with locating pins for locating the corresponding first mounting holes; the tensioning mechanisms are provided with tensioning pins capable of tensioning the corresponding second mounting holes through changing of the outer diameter; and the clamping mechanisms can clamp the rear ends of the corresponding sliding rails. The universal locating and tensioning tray for seat frame assembling is suitable for various types of seats and can meet inspection requirements.

Description

technical field [0001] The invention relates to the technical field of automobile seats, in particular to a universal positioning and tensioning tray for seat frame assembly. Background technique [0002] The installation of the car seat frame and the vehicle body is to connect the two slide rails under the seat frame with the body with screws. In the production of various OEM seats, due to the differences in the chassis structure and environmental parts of each OEM body, the size of the slide rails that are installed with the body is different, and the size of the mounting holes for setting screws on the slide rails is quite different. When using a seat, a compatible tray is needed to position the locking slides. However, the existing compatibility trays use telescopic pins to position the slide rails to adapt to different seat assemblies. Since the length of the slide rails of the seat frame is generally about 500mm, the holes that can be used for positioning are limited ...

Problems solved by technology

However, the existing compatibility trays use telescopic pins to position the slide rails to adapt to different seat assemblies. Since the length of the slide rails of the seat frame is generally about 500mm, the holes that can be used for positioning are limited and can only be used for 3 ~ 4 types of seat frames; since the seat frame needs to be tested for functionality after assembly, the existing clamping method uses two split claws to clamp the outer rail of the slide rail, but when doing functional testing , because it is necessary to slide the frame body on the slide rail relative to the slide rail for inspection, the claws will interfere with the parts on the frame body when sliding, so the clamping method of the claw structure is only suitable for the assembly requirements of the seat frame. Unable to meet testing needs
