Description

Technical Field

[0001] The utility model relates to the field of steering knuckle coding in the automobile parts industry, in particular to a flippable positioning tool. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the steering axle of the car. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the load on the front of the car, support and drive the front wheel to rotate around the kingpin to steer the car. After the steering knuckle is manufactured, it needs to be coded and numbered. At present, when coding the steering knuckle, it is mainly fixed by manual operation, and then the steering knuckle is moved to the coding position for positioning and coding. After the coding is completed, the steering knuckle needs to be disassembled. This coding method of the steering knuckle is not only labor-intensive, but also inefficient, which greatly increases the production cost. Summary of the invention

[0003] Therefore, it is necessary to provide a device that can improve the efficiency of steering knuckle coding, reduce manpower input, and reduce production costs.

[0004] To achieve the above-mentioned purpose, the inventor provides a flip-over positioning tool, including a base assembly, a receiving plate and an air valve assembly, wherein the base assembly is movably connected to the receiving plate, the air valve assembly is arranged on the base assembly, and the base assembly can control the receiving plate to rotate and switch between the horizontal and vertical positions; a positioning clamping mechanism for fixing the steering knuckle is arranged on the receiving plate, and the positioning clamping mechanism can change its position following the receiving plate.

[0005] Furthermore, the base assembly includes a base plate, a bracket, a telescopic cylinder, and a driving arm. The bracket and the telescopic cylinder are installed on the base plate. A bearing seat is provided on the bracket, and a bearing is provided on the bearing seat. One end of the driving arm is hinged to the telescopic end of the telescopic cylinder, and the other end passes through the bearing; swing arms are provided at both ends of the supporting plate, and the swing arms are fixedly connected to one end of the driving arm passing through the bearing.

[0006] Furthermore, the driving arm and the swing arm are fixedly connected via a tightening sleeve.

[0007] Furthermore, the positioning and clamping mechanism includes a positioning component, a guide component, a fixing device and a support column, and the positioning component, the guide component, the fixing device and the support rod are all installed on the receiving plate.

[0008] Furthermore, the fixing device is a clamping cylinder.

[0009] Furthermore, there are two positioning and guiding mechanisms installed on the receiving plate.

[0010] Furthermore, a limit block is arranged on the bracket.

[0011] Different from the prior art, the above technical solution has the following beneficial effects:

[0012] The utility model provides a positioning clamping mechanism on the receiving plate, and uses the base assembly to drive the receiving plate to flip, thereby driving the workpiece fixed by the positioning clamping mechanism to flip. The robot can directly grasp the workpiece and place it on the tooling, quickly position and fix the workpiece, and adjust the workpiece to a specified position by flipping, which is convenient and fast for coding. At the same time, the workpiece can also be quickly disassembled, thereby improving the coding efficiency of the workpiece, reducing the input of manpower, and reducing the production cost.
