[0006] The part is an automotive component. The pin needs to be pressed vertically into the hole of the part 11, and the exposed parts at both ends need to be consistent, otherwise it will affect the customer's assembly. However, the pin has a diameter of only 4mm and a length of 4mm, which makes it easy to put it crooked, resulting in a low yield rate of the pressed part 11. It is more dangerous to assemble it directly with a press.

[0007] Therefore, we propose a rocker arm fixture that is convenient for pin positioning and correction, so as to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of the utility model is to provide a rocker tooling which is convenient for positioning and guiding pins, so as to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a swing arm tooling that is convenient for positioning and guiding pins, comprising: a tooling base and a pin positioning block, wherein a square cover plate is mounted on the tooling base;

[0010] A spring is installed between the pin positioning block and the square cover plate via a spring positioning pin;

[0011] A square hole for inserting the pin is provided on the pin positioning block, and the pin enters the hole in a vertical state.

[0012] Preferably, a plurality of square cover plates are provided according to the size of the parts.

[0013] Preferably, the pin positioning block is fixedly mounted on the square cover plate by two pairs of screws and nuts.

[0014] Preferably, a part is placed under the pin positioning block and positioned by a square cover plate to ensure that the pin placement position and the part assembly hole are coaxial.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The part is inserted under the pin positioning block along the square cover and fixed so that the hole of the part is concentric with the hole of the pin positioning block. The pin is placed on the small hole in the pin positioning block and allowed to fall freely. After automatic correction, it is above the hole of the part. The operating lever is pulled and the punch moves downward to press the pin into the part hole to complete the assembly. This tooling solves the problem of pins being easily placed crooked without positioning and correction, greatly improving the yield rate of parts. BRIEF DESCRIPTION OF THE DRAWINGS
