Manual repair welding was required to ensure product quality. To facilitate worker operation and improve efficiency, a positioner needs to be developed to increase production efficiency. Currently, the most commonly used positioners on the market are electrically controlled positioners, which use motors to control the free rotation of the clamps. However, this type of positioner has a long development cycle and high cost in the early trial production phase, and it cannot be used for small-batch production.

[0003] Therefore, there is a need for a low-cost positioner for chassis suspension that can adapt to large-scale model changes. Summary of the Invention

[0005] The purpose of this utility model is achieved by the following solution: A manual positioner for an automobile chassis suspension includes a mounting base, mounting brackets at both ends of the mounting base, a clamp between the two mounting brackets, a mounting shaft on the mounting bracket, and the two ends of the clamp connected and fixed to the mounting shaft. A braking device is mounted on the mounting bracket at the left end of the mounting base. The braking device includes a mounting seat on the upper surface of the left end of the mounting base, the upper end of the mounting seat is hinged to a brake pedal, the front end of the brake pedal extends outward from the mounting bracket, and the middle section of the brake pedal is connected and fixed to the lower end of a connecting rod. The upper end of the connecting rod is hinged to the lower end of the positioning pin, the upper end of the positioning pin engages with the positioning plate, and the positioning plate is fixedly connected to the mounting shaft. The fixture includes a fixture frame fixedly connected to the mounting bracket. The center of the mounting frame is a space for placing the chassis suspension. A crossbeam is provided at the lower end of the middle section of the left and right sides of the fixture frame. A quick clamp for clamping the chassis suspension is provided on the upper end of the middle section of the crossbeam. The lower ends of the left and right sides of the fixture frame are respectively fixedly connected to the support pins for supporting the chassis suspension. The left and right ends of the front frame of the fixture frame are respectively fixedly connected to the positioning pins for positioning the chassis suspension.

[0006] The positioning disk has multiple positioning grooves around its circumference for positioning.

[0007] A sensor is installed on the mounting bracket at the right end of the mounting base, and the lower end of the quick clamp is connected and fixed to the sensor through a sensor connecting rod.

[0008] The quick-release caliper includes a mounting bracket mounted on a crossbeam. A vertical shaft is located in the center of the mounting bracket. The upper end of the vertical shaft passes through the upper end face of the mounting bracket and is connected and fixed to a rotating shaft. The horizontal arms at both ends of the rotating shaft are respectively hinged to one end of a connecting rod. The other end of the connecting rod is connected and fixed to a pressure plate. The side arm of the rotating shaft is connected and fixed to a handle. The lower end of the vertical shaft is hinged to a sensor connecting rod.
