[0005] The utility model discloses an automobile chassis subassembly mechanism, aiming to solve the technical problem of stably screwing screws into the automobile chassis.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The camshaft is an axially coupled machine which is adapted to engage the first and second end of the guide rails and to engage with the guide rails on one side of the camshaft and the other side of the cam.

[0008] By setting up a tightening mechanism, after the device is positioned, the screws can be screwed into the chassis of the car, and the installation of the screws can be automatically completed. The setting of the first track box can limit the first sliding block, so that the first sliding block can produce an effect of vertical up and down movement in the inner cavity of the first track box. The setting of the servo motor can rotate the rotating rod and the threaded tube after the power is connected. By setting up a positioning mechanism, the device can be positioned in the chassis of the car, and can adapt to the positioning work of different car chassis, so that the screws will not loosen during the installation process.

[0009] In a preferred embodiment, the tightening mechanism also includes a threaded ring, which is fixedly connected to the inner surface of the frame, and the threaded pipe is threadedly connected to the inner cavity of the threaded ring. A magnet is fixedly connected to the top surface of the inner cavity of the threaded pipe, and the hole shape of the threaded pipe is hexagonal.

[0010] By setting a threaded ring, the threaded tube can be limited so that the threaded tube can move up and down when rotating. The setting of the magnet can adsorb the screw, so that the screw can be positioned in the inner cavity of the threaded tube when installing it.

[0011] In a preferred embodiment, a card slot is provided on the outer surface of the second track box, and the outer surface of the sliding rod is fixedly connected to the third sliding block, and the third sliding block passes through the second track box, and the outer side surface of the second track box is located directly above the third sliding block and is fixedly connected to a fixing block, and a spring is fixedly connected between the opposite surfaces of the third sliding block and the fixing block, and a soft pad is fixed on the outer surface of the positioning plate, and the number of the soft pads is several, and the several soft pads are evenly distributed, and the outer surface of the positioning plate is provided with an anti-slip groove, and the positioning mechanism also includes a fixing frame, the fixing frame is threadedly connected to the inner side surface of the frame, the inner cavity of the fixing frame is fixedly connected to a limiting tube, and the inner cavity of the limiting tube is slidably connected to an extrusion rod, and the end of the extrusion rod is fixedly connected to the outer surface of the moving plate. The positioning mechanism also includes a fixing rod, which is fixedly connected to the inner side surface of the frame, and a hydraulic press is arranged at the end of the fixing rod, and the end of the extrusion rod away from the moving plate is fixedly connected to the output end of the hydraulic press.

[0012] By setting the third sliding block, the sliding rod can slide more stably. The spring can squeeze the third sliding block so that the sliding rod always moves downward. The soft pad and the anti-skid groove can increase the friction between the positioning plate and the chassis of the car. The fixed frame and the limiting tube can limit the extrusion rod so that the extrusion rod can move more stably. The hydraulic press can be controlled to achieve the effect of making the extrusion rod drive the moving plate to move.

[0013] As can be seen from the above, an automobile chassis subassembly mechanism has the following improvements and advantages compared with the prior art:

[0014] First, by setting a tightening mechanism, after the device is positioned, the screws can be screwed into the chassis of the car, and the installation of the screws can be automatically completed.

[0015] Secondly, by setting a positioning mechanism, the device can be positioned in the automobile chassis and can adapt to the positioning work of different automobile chassis, so that the screws will not loosen during installation. BRIEF DESCRIPTION OF THE DRAWINGS
