Problems solved by technology

[0003] At present, the positioning and locking methods for shaft workpieces are usually clamped and fixed by mechanical fixtures. Two or more clamping blocks arranged oppositely are screwed by bolts and other mechanisms to clamp the shaft between the clamping blocks. For such workpieces, this operation method requires manual operation, and it is difficult to ensure the balance of the clamping force, and the manual operation is time-consuming and laborious; some of them use pneumatic positioning fixtures, the locking force is small, the brake is not reliable, and it is difficult to ensure processing. precision

Abstract

The invention discloses a hydraulic locking device for installing shaft workpieces for turning and belongs to the technical field of turning equipment. The hydraulic locking device solves the problemsthat when an existing shaft workpiece is turned, stability is poor, and fixing is difficult. According to the technical key points, the hydraulic locking device comprises a turning machine tool, a portal rack, a turning mechanism, a shaft workpiece assembling table and a shaft workpiece locking table. A hydraulic locking mechanism is installed on the shaft workpiece locking table and comprises ahydraulic locking sleeve, a rear stop cover and a hydraulic locking cylinder, wherein the rear stop cover is installed at the rear end of the hydraulic locking sleeve, and the hydraulic locking cylinder is installed on the rear stop cover. According to the hydraulic locking device, the shaft workpiece assembling table and the shaft workpiece locking table are matched, the shaft workpieces can be placed stably, under the cooperative use of the hydraulic locking sleeve and the hydraulic locking cylinder, the shaft workpieces with hollow portions arranged on the end portions can be locked and fixed internally and externally together, and the fixing stability of the shaft workpieces is improved.

Description

technical field [0001] The invention relates to the technical field of turning processing equipment, in particular to a hydraulic locking device for installing shaft workpieces for turning processing. Background technique [0002] Shaft workpieces are widely used in transmission mechanisms, especially in vehicles, large machinery and other equipment; in the turning process of shaft workpieces, the upper end surface of the shaft after forging needs to be machined Cutting to form a flat and smooth end face of the shaft or turn some threaded holes, counterbores and through holes on the end face. When turning it, the shaft workpiece needs to be positioned and locked. [0003] At present, the positioning and locking methods for shaft workpieces are usually clamped and fixed by mechanical fixtures. Two or more clamping blocks arranged oppositely are screwed by bolts and other mechanisms to clamp the shaft between the clamping blocks. For such workpieces, this operation method req...
