[0002] The production and assembly of automotive parts often involves various types of multi-links, such as tie rods. Their basic structure consists of a metal rod with two elastic hinges. The metal rod is a stamped part, and the two elastic hinges are a combination of rubber and metal sleeves. The two elastic hinges have different lengths but identical dimensions. This means that two bushings of different lengths are pressed into a single metal rod. The two apertures in the metal rod have the same diameter, and the two bushings are identical in all other dimensions except for their length. However, during press assembly using tooling, these bushings are often installed in the wrong direction, resulting in rework and scrap. Summary of the Invention

[0009] The utility model discloses a press head and press seat, press seat contains lower mounting plate, upper mounting plate and floating plate, lower mounting plate is equipped with the column and drive cylinder no.
[0010] Limiting piece no.

[0012] The working process of the utility model discloses:
[0013] Place parts: floating plate 4 is in initial position (the position close to limiting piece c and limiting piece d), and horizontal pull rod part 25 is placed on floating plate 4, and long short hinge is placed into long short hinge mounting seat respectively.
[0014] Floating block is in place: the floating plate moves upward under the action of cylinder a and cylinder b, and stops when it is close to the upper mounting plate. The floating plate is sleeved on sliding column 1 and sliding column 2 to move up and down. At this time, cylinder c and cylinder d are started, pushing limit block a and limit block b to move inward, just moving to the top of limit block c and limit block d. At this time, the floating plate will not move downward under the support of the limit block.
[0015] Press-fitting: The long hinge pressing head and the short hinge pressing head move downward to press the long and short hinges into the cross-tie rod. At this time, the cross-tie rod is located on the floating plate, and the floating block will not move downward under the action of limit blocks a, limit blocks b, limit blocks c, and limit blocks d, so the press-fitting is successfully achieved.
[0016] Reset: Cylinders c and d are started to pull limit blocks a and b outwards, so that limit blocks a and b leave the top of limit blocks c and d. Then cylinders a and b are started to pull the floating plate downwards, so that the floating plate stops on limit blocks c and d. The cross-bar with the hinge pressed can be smoothly removed from the floating block.
[0017] The utility model has two pressing heads for respectively pressing two elastic hinges of different lengths. An infrared emitting and receiving device is installed at each end of the outer sides of the long and short hinges, and a reflector is placed near the long and short hinges. When the prescribed short hinge is placed on the left side, the infrared light emitted by the infrared emitting device on the left side can be irradiated onto the reflector without hindrance. The reflector will reflect the infrared light back to the infrared receiving device. At this time, the infrared receiving device receives the infrared light and determines that the hinge on the left side is correct and displays a correct signal; otherwise, it is an error. When the prescribed long hinge is placed on the right side, the infrared light emitted by the infrared emitting device on the right side irradiates the long hinge. The infrared light is absorbed by the long hinge and cannot irradiate onto the reflector and is reflected back to the infrared receiving device. At this time, the infrared receiving device does not receive the infrared light and determines that the hinge on the right side is correct; otherwise, it is an error and displays an error signal.
[0018] This utility model utilizes the different lengths of the two bushings to prevent errors. By installing an infrared emitting device at each end of the press-fitting long and short bushings, the infrared rays on the long bushing side are blocked, while the infrared rays on the short bushing side pass freely, thus achieving the purpose of error prevention. We utilize mechanical and photoelectric principles to achieve error prevention during press-fitting.
