Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of V-shaped blocks, in particular to a rotatable V-shaped block. Background Art
[0002] This V-block is placed on the workbench as a part of the hydraulic straightening machine. The workpiece to be straightened, such as shaft parts, profiles, etc., is placed on the V-block. The hydraulic pressure of the hydraulic cylinder is used to apply pressure to the workpiece for straightening to achieve the required straightness and other requirements.
[0003] Ordinary V-blocks have a notch on the top for placing round steel. They only have the simple function of supporting the round steel. When the round steel needs to be straightened multiple times at different angles, it needs to be rotated multiple times for straightening. However, when the workpiece becomes larger or heavier, it becomes more difficult to rotate. Utility Model Content
[0004] The utility model aims to provide a rotatable V-shaped block.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A rotatable V-block comprises a V-block, wherein the upper end wall of the V-block is provided with an opening, a roller shaft is passed through the end wall of the V-block close to the opening, a cylindrical roller bearing is installed on the middle end side of the roller shaft, and a spacer is installed between the roller shaft close to the cylindrical roller bearing and the V-block.
[0007] Preferably, the top end wall of the V-shaped block is in the shape of a V.
[0008] Preferably, the V-block and the roller shaft are fixedly connected.
[0009] Preferably, the roller shaft and the cylindrical roller bearing are rotatably connected to each other.
[0010] Preferably, the roller shaft and the spacer ring are snap-fitted and sleeved together.
[0011] Preferably, the roller shaft, cylindrical roller bearing and spacer are symmetrically distributed about the center of the V-block.
[0012] The utility model has at least the following beneficial effects:
[0013] 1. The roller shaft and the cylindrical roller bearing rotate, and the roller shaft is rotated. The two roller shafts arranged opposite to each other rotate, and the round steel processed by the straightening machine placed between the two roller shafts is used to roll and rotate, which is convenient for material transfer. Two cylindrical roller bearings with super high load-bearing strength are installed on the V-block. The advantage is that when the workpiece needs to be straightened multiple times at different angles, it can be done by rotating the workpiece, because it is supported on high-strength rolling bearings, it is quite easy and flexible to rotate, which improves the straightening efficiency;
[0014] 2. Connect the two roller shafts through the V-block, and sleeve the cylindrical roller bearings and spacers on the roller shaft ends. Use the notch on the top of the V-block to overlap the two ends of the round steel to support the round steel and facilitate the processing of the round steel. The V-block has certain precision requirements on the coaxiality and symmetry of the two rolling shaft holes, so it has certain precision requirements on the processing equipment. It improves the straightening efficiency of some shaft parts, improves work efficiency, and reduces labor costs, so it is very popular with customers. BRIEF DESCRIPTION OF THE DRAWINGS
