Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a new tooling fixture for processing a hydraulic valve body. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. A hydraulic valve body is usually composed of different hydraulic valve blocks. When the hydraulic valve body needs to be processed, the hydraulic valve block is processed first, and then the hydraulic valve blocks are assembled to form a hydraulic valve after the processing is completed. In the process of processing the hydraulic valve block, it is found that some existing small stamping and hole-opening machine tools have stamping tools such as drills on them, and a bed plate underneath. The hydraulic valve block to be processed is located on the bed plate, and there are clamps on both sides of the hydraulic valve block. After the hydraulic valve block is positioned, the screw on the clamp is turned, and the screw is connected to the bed plate through a thread. The front end of the screw is rotatably connected to the hydraulic valve block. The screw is turned to drive the clamp to clamp the hydraulic valve block, and then punching and drilling are started. In the process of drilling, it is found that since the hydraulic valve block is located on the bed plate, when you want to drill When a hole is drilled through the hydraulic valve block, it will cause certain damage to the bed plate below. Over time, if there are too many holes in the bed plate, it will gradually become scrapped and unusable, and the next bed plate needs to be replaced. The existing solution is to mark the hydraulic valve block, first drill a hole in the valve block on one side, then flip the valve block after completion, and drill a hole in the valve block on the other side. However, this method also has certain defects. If the mark is not accurate enough, the through holes on the valve block will not match, thereby affecting the use of the valve block. In addition, since it is a small drilling machine tool, it is impossible to fix and flip the valve block by a clamp. The valve block can only be released first, and then fixed after flipping it. This is troublesome, time-consuming and labor-intensive. For this reason, we propose a new tooling fixture for processing hydraulic valve bodies. Utility Model Content

[0032] Under normal circumstances, the handle 5 remains stationary, the triangular block 11 also does not move, and the inclined block 61 also does not move. The plate 14 is supported by the inclined block 61 to place the hydraulic valve block. At this time, the hydraulic valve block is allowed to drill holes normally on the plate 14, but a through hole cannot be drilled. When a through hole is to be drilled, the pull rod 73 is first pulled to drive the shaft 1 71 to slide, and then drive the block 2 7 to slide, so as to release the lock of the handle 5. After the release is completed, the handle 5 is slid on the groove 2 13 to drive the column 12 to move, and then drive the triangular block 11 to move. The inclined block 61 was originally supported by the triangular block 11 and abutted against the plate 14.
