Problems solved by technology
[0002] Before any workpiece enters the machining process, it is necessary to draw a machining datum line on the component, and the pin frame used for the internal arm frame transmission of the ship loader is no exception. This structure is like "π" and there is no reinforcing rib inside. , according to the traditional processing technology for boring, because the structural strength is not enough, and there is not enough marking plane, it is difficult to ensure the parallelism and perpendicularity of the pin hole after processing
The traditional process is to bore one by one according to the positioning reference of the marking line of the structural part. Due to the insufficient structural strength and the deviation of the marking line, the processed pin holes cannot meet the installation requirements of the equipment.

Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] A method for processing a transmission pin frame of a telescopic boom frame of a ship loader, comprising the following steps:
[0020] refer to figure 1 , Step 1. Position the pin frame according to the center line of the lower track, ensure that the center line of the pin frame is parallel to the center line of the track, and adjust the pin frame to fit closely with the support of the telescopic arm frame, and then temporarily fix it to the structure;
[0021] Step 2. Install the pin frame, and connect the pin seat with the telescopic arm frame with process bolts. Each bolt hole must be installed with process bolts and tightened;
[0022] Step 3. Re-calibrate the pin frame, and then install the holding bracket;
[0023] Step 4. According to the coordinate value, draw the center cross line of the first hole and the last hole of each pin frame, and ensure tha...

The invention discloses a machining method for a transmission pin frame of a ship loader telescopic boom. The machining method comprises the following steps that firstly, the pin frame and the telescopic boom are adjusted to be tightly attached together; secondly, the pin frame is installed; thirdly, the pin frame is recalibrated; fourthly, a horizontal datum line is marked on a pin maintain frame; fifthly, pin holes are formed; sixthly, a pin frame panel is fixedly clamped downwards; seventhly, the horizontal datum line is leveled, and a length central line is adjusted; eighthly, a machining starting point is positioned according to the circle center, of a starting hole, marked in the pin frame; ninthly, after machining is finished, a spot welding portion is polished to be flat. According to the machining method for the transmission pin frame of the ship loader telescopic boom, the problem that the parallelism degree and verticality after pin hole forming cannot be ensured easily due to the fact that structural strength is not high enough and no enough scribing planes exist in a traditional machining process for boring is solved, and machining strength and precision are improved.
