Problems solved by technology
[0003] However, the existing hydraulic locking structure of the CNC tool post has some shortcomings during use. The previous fixing method will cause the position of the CNC tool post to shift during the long-term vibration of the lathe, so that the turning tool The cutting position is shifted, resulting in reduced turning accuracy

The invention discloses a hydraulic locking device, which comprises a numerically controlled tool rest and a fixing card. The top of the numerically controlled tool rest is provided with a tool fixing bolt for limiting the position of the tool. The bottom of the numerically controlled tool rest is welded with a fixed base, and the The bottom of the base is connected with the lathe connection mechanism through the concave-convex connection layer, and the top plate of the fixed base is slidably connected with the fixed bearing on the right-angle bending telescopic rod through the ring chute. In the present invention, a concave-convex connection layer is arranged between the fixed base and the lathe connection mechanism, and the outer side of the fixed base and the lathe connection mechanism are engaged by the fixed bearing and the fixed card on the right-angle bending telescopic rod, further improving the fixed base and the lathe connection mechanism. The fixed position is fixed, and the fixed bearing is located in the circular chute in the fixed base, so that the locking device in this way can be applied to various types of lathes, and the applicable range is wider.
Description
technical field [0001] The invention relates to the technical field of numerical control lathe equipment, in particular to a hydraulic locking device. Background technique [0002] CNC tool post is the most common auxiliary device for CNC lathes. It enables CNC lathes to complete various or even all processing procedures in one clamping of the workpiece, so as to shorten the auxiliary time of processing and reduce the number of workpieces due to multiple installations during the processing. The error caused by it can improve the machining efficiency and machining accuracy of the machine tool. The development trend of CNC tool holders is: with the development of CNC lathes, CNC tool holders have begun to develop in the direction of quick tool change, electro-hydraulic combined drive and servo drive. At present, domestic CNC tool holders are mainly electric, which are divided into two types: vertical and horizontal. The vertical tool post has two forms of four and six statio...
