Problems solved by technology

The components of this hydraulic piston clamping mechanism are prone to aging, and there is a risk of hydraulic oil leakage, and the designed stroke of the piston of this clamping mechanism is a fixed stroke, and the clamping force of the piston on the workpiece is controlled by a pressure valve, which can only be used for The workpiece exerts a fixed jacking force
When there is no workpiece on the workbench, the piston cannot stay at any position, which is obviously unreasonable for workpieces with different heights and shaft diameters. In addition, once the hydraulic seal or balance system fails, the top will slide to the lowest position in a natural state. , there is a certain security risk

Abstract

The invention discloses a workpiece jacking mechanism for a vertical turning center. The workpiece jacking mechanism comprises an alternating-current motor, a transmission mechanism, a sliding sleeve and a centre. The output end of the alternating-current motor is connected with the input end of the transmission mechanism. The output end of the transmission mechanism is connected with the sliding sleeve. A first rotary bearing and a second rotary bearing are mounted on the upper portion and the lower portion in the sliding sleeve correspondingly and are provided with a connecting shaft. The centre is fixed to the bottom end of the connecting shaft. The transmission mechanism is mounted in a first box body. A sliding sleeve is mounted in a second box body. The second box body is fixed to the bottom end of the first box body. The jacking mechanism is a mechanical jacking mechanism, the jacking mechanism adopts the alternating-current motor to drive the sliding sleeve to move up and down, workpiece jacking is achieved, and machining of large-length-diameter-ratio workpieces in the vertical turning center is achieved. No hydraulic mechanism is adopted in the mechanical jacking mechanism, and failures caused by the problems of hydraulic element ageing, hydraulic oil leakage and the like can be fundamentally eradicated.

Description

technical field [0001] The invention relates to a workpiece clamping mechanism, in particular to a workpiece clamping mechanism for a vertical turning center. Background technique [0002] The traditional workpieces processed by large and heavy-duty CNC vertical turning machining centers are short and thick parts, and the length-to-diameter ratio is generally less than 1. When processing workpieces under this length-to-diameter ratio, it is only necessary to clamp the workpiece with the workbench. However, workpieces with an aspect ratio greater than 1 can usually only be processed on large horizontal lathes. In the absence of a large horizontal lathe, when it is necessary to process a workpiece with a large length-to-diameter ratio and require high machining accuracy, it may be considered to install a workpiece clamping mechanism on the vertical lathe, relying on the ram installed on the lathe beam The tool rest is used to complete the entire workpiece processing process, ...
