Problems solved by technology

[0003] Existing vises generally use one side of the workpiece as the benchmark for processing. When the processing process is based on the center of the workpiece, manual alignment is required, which prolongs the processing preparation time, inconvenient operation and reduces production efficiency.
At the same time, the positioning accuracy of the existing vise is poor, and cumulative errors will occur during the assembly and processing of the workpiece for a long time, resulting in errors in the assembly and processing of the workpiece later, affecting the assembly and processing accuracy of the workpiece, and there will be iron filings during use and other foreign matter enter from the gap of the shell, pollute the screw or damage the thread, and affect the rotation of the screw

Abstract

The invention discloses a self-centering vice, and belongs to machining positioning equipment. The self-centering vice comprises a base, two vice bodies, a screw rod, a fixed seat, a locking nut, anda plurality of pressure bearings; the two vice bodies are movably arranged on the base; the screw rod is rotated to drive the vice bodies to move centripetally or centrifugally; and a novel installation ring table is arranged in the middle of the screw rod, arranged between the pressure bearings and integrally installed in the fixed seat through the locking nut. According to the self-centering vice, compared with an existing structure, a novel positioning and locking installation structure is adopted, so that the center of a workpiece can be automatically positioned, and the repeated positioning accuracy can reach 0.002 mm or above; and a clamping part arranged on the vice has a wide clamping face, so that the clamping reliability and the stability are high, and the adaptability is high.

Description

technical field [0001] The invention belongs to machining positioning equipment, in particular to a self-centering vise. Background technique [0002] In the field of machining, a vise is a common fixture, which consists of a base and two pliers, one of which is fixed on the base, and the other slides freely on the base. When clamping the workpiece, the movable pliers move to the fixed pliers, so that one side of the workpiece is tightly attached to the fixed pliers. [0003] Existing vises generally use one side of the workpiece as the benchmark for processing. When the processing technology is based on the center of the workpiece, manual alignment is required, which prolongs the processing preparation time, inconvenient operation and reduces production efficiency. At the same time, the positioning accuracy of the existing vise is poor, and cumulative errors will occur during the assembly and processing of the workpiece for a long time, resulting in errors in the assembly ...
