[0002] The main function of the balancing ear seat is to hinge the top beam and the shield beam through the jack. Its structure usually includes two balancing ear plates and a partition. The balancing ear plates and the partition are combined together by welding. The balancing ear plate is a plate structure with a hinge hole and a non-processed hole in its structure; the partition is a casting with a 45-degree bevel on each side. Since the partition is usually a casting structure, it requires casting, tempering, shot blasting, turning, and milling processing steps. The balancing ear plate is usually a blanking part, which requires CNC blanking and milling. Finally, the three parts are assembled, bored, and welded to form a finished balancing ear seat. The process route is long, the production cost is high, the production efficiency is low, the quality of the casting is unstable, there are casting defects, and the thickness of the partition is not easy to adjust.

The partition plate and the sticking plate are used to separate the two balancing ear plates so that a cavity for accommodating the hinged end of the jack is formed between the two balancing ear plates.

[0008] Based on the above, for the convenience of processing, shortening the process route and improving production efficiency, the partition plate is welded to the patch plate, and the partition plate and the patch plate are respectively cut and blanked by a cutting machine.

[0009] Based on the above, for the convenience of installing the sleeve and the jack, sleeve installation holes and hinge shaft installation holes are respectively formed in the balance ear plate, and the hinge end of the jack is installed in the hinge shaft installation hole through a hinge shaft.

[0010] Based on the above, in order to avoid interference with the hinge end of the jack, a relief groove is formed on one side of the balance ear plate.

[0011] Based on the above, for the convenience of welding and increasing the weld width, bevels are respectively formed on both sides of the patch plate and on the partition plate close to the balance ear plate. The partition plate is welded to one of the balance ear plates, and the patch plate is welded to the other balance ear plate.

[0012] Based on the above, in order to avoid interfering with the hinge shaft of the jack, a first arc-shaped groove is formed on the patch plate, and a second arc-shaped groove is formed on the partition plate, and the first arc-shaped groove and the second arc-shaped groove are correspondingly arranged.

[0013] Based on the above, the thickness value of the patch plate is less than the thickness value of the partition plate.

[0014] Based on the above, in order to avoid interfering with the movement of the jack, the two rib plates have different specifications. The height value of the rib plate located at the hinge end of the jack is less than the height value of the other rib plate.

[0015] The utility model has substantial features and progress compared with the prior art. Specifically, for the balance ear seat of the hydraulic support provided by the utility model, by changing the partition plate from a casting to a blanking part, splitting one piece into two pieces and then welding them together. During production, blanking and cutting are carried out by a numerical control cutting machine to respectively cut out the blank materials of the partition plate and the patch plate, and then groove cutting is carried out by a robot. The patch plate is cut with double-sided grooves, and the partition plate is cut with single-sided grooves. After the groove processing is completed, the two partition plates are welded together to form a partition plate assembly, and the partition plate assembly is welded together with the balance ear plate, and then boring and welding are carried out. Thereby, the transportation cost and manufacturing cost are saved, the manufacturing process is shortened, the generation of defects such as casting sand holes, shrinkage holes and inclusions can be effectively avoided, the part quality and welding quality are improved, and the structure is changed from an integral one to two pieces welded together, and the thickness can be freely combined according to actual needs.
