Embodiment Construction
[0008] Such as figure 1 Shown: 13 is tailstock body, sleeve 2 is equipped with in the inboard of tailstock body 13, and tailstock main shaft 1 is installed by bearing in sleeve 2 inboard. A mounting hole is horizontally processed on the top of the tailstock body 13, and symmetrical left clamping blocks 10 and right clamping blocks 12 are housed in the mounting holes. The opposite ends of the left clamping block 10 and the right clamping block 12 are processed with cylindrical surfaces matching the outer surface of the sleeve 2 .
[0009] The left clamping block 10 and the right clamping block 12 all have an axial central hole, and a connecting rod 11 is arranged in the central hole, and the right end of the connecting rod 11 is fixedly connected with the right clamping block 12, and the fixing method is on the right clamping block 12 Insert the limiting block 14, and the limiting block 14 is just inserted in the radial groove on the connecting rod 11, so that the connecting r...

The invention discloses a hydraulic elastic sleeve type tailstock, which comprises a tailstock body, wherein a sleeve is arranged inside the tailstock body, an apex main shaft is arranged in the sleeve through a bearing, the upper part of the tailstock body is provided with a transverse mounting hole, a left clamping block and a right clamping block which are symmetrical are arranged in the mounting hole, and the left clamping block and the right clamping block are provided with cylindrical surfaces matched with the outside surface of the sleeve; and the left clamping block and the right clamping block are provided with an axial central hole, a connecting rod is arranged in the central hole, the right end of the connecting rod is fixedly connected with the right clamping block, the left end of the connecting rod is connected with a piston, an oil cylinder matched with the piston is fixedly connected with the left end of the left clamping block, a butterfly spring is arranged between the piston and the left end of the left clamping block, and an oil cavity on the left side of the piston is communicated with a pipe joint at the end of the oil cylinder. After installation, the left clamping block and the right clamping block relatively clamp the sleeve due to the action of the butterfly spring, oil is supplied to the oil cavity through a hydraulic device, the butterfly spring is compressed, and the left clamping block and the right clamping block relatively loosen the sleeve, so clamping and loosening of the sleeve do not need to be manually operated, and the operation is flexible and reliable.
Description
technical field [0001] The invention relates to a tailstock, in particular to a hydraulic elastic sleeve type tailstock suitable for large numerically controlled lathes. Background technique [0002] The locking or loosening between the sleeve and the tailstock of the existing large-scale CNC lathe is manually performed by the operator. When the size of the machine tool increases, the height of the tailstock will increase accordingly, making manual locking difficult. , Increase the work intensity of the operator, time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic elastic sleeve type tailstock with simple structure, flexible and reliable action, and no need for manual operation. [0004] The hydraulic elastic sleeve type tailstock of the present invention includes a tailstock body, a sleeve is arranged inside the tailstock body, a top spindle is installed in the sleeve through a bearing, and...
