Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an adjustable mounting bracket for a hydraulic tool rest. Background Art

[0002] The processing of slender shaft parts is one of the difficult problems in mechanical processing. Due to the large aspect ratio of the workpiece, the rigidity of the entire process system is poor during processing. At a higher speed, the process system is prone to vibration, which causes a sharp deterioration in processing conditions and makes processing impossible. Even if a very low speed and a very small cutting depth are used, the deformation of the process system is quite serious, causing a large cylindrical error in shaft parts, and vibration marks often appear on the surface, making it impossible to guarantee processing accuracy and surface quality. The main method to solve this problem in production is to install a center frame. When processing long materials, the spindle end clamps the workpiece, and the tailstock end assists in tightening the workpiece at the other end. The center frame is fixed at a set position in the middle to assist in clamping and supporting the workpiece. When the process requires the center frame to move synchronously with the tool, a hydraulic tool holder needs to be installed. The hydraulic tool holder retains the function of the center frame and can move with the tool.

[0003] Generally, the hydraulic tool rest for small machine tools is installed on the machine tool saddle and moves linearly synchronously with the saddle components. However, due to the higher requirements for load-bearing or processing accuracy on large machine tools, the hydraulic tool rest is not suitable for being placed on the machine tool saddle due to weight or size restrictions. It can only be installed on the tailstock guide rail. Since the machine tool tailstock and the machine tool saddle are on two independent guide rails, the hydraulic tool rest needs to maintain coaxiality with the spindle. This requires that the hydraulic tool rest installed on the tailstock guide rail needs to be adjusted according to the position of the spindle. However, the current hydraulic tool rest does not have an adjustment function, and it is difficult to ensure the coaxiality of the hydraulic tool rest and the machine tool spindle.
