Abstract

The invention discloses a pressure controllable type worm self-locking anti-loose fine adjusting clamp, and belongs to the field of clamps. The clamp comprises a clamp seat, a left fixing block, a large screw rod, a left clamping block, a right clamping block, a guide rod, a fine adjusting screw rod, a right fixing block, worm self-locking anti-loose devices, a worm gear, a worm and a dial. A dovetail groove is formed in the clamp seat, the left fixing block and the right fixing block are arranged at the two ends of the dovetail groove, threads are arranged at the two ends of the fine adjusting screw rod, one end of the fine adjusting screw rod is assembled in a threaded hole of the guide rod, the other end of the fine adjusting screw rod is meshed with threads of the right fixing block, the turning directions of the threads at the two ends of the fine adjusting screw rod are the same, the worm self-locking anti-loose devices are arranged on the large screw rod and the fine adjusting screw rod respectively, and the dial is fixedly arranged on the worm. The problem that an existing clamp is difficult to adjust finely, low in locating precision and prone to being loosened, and clamping force is hard to control is solved, and the clamp has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of fixtures, and more specifically relates to a pressure-controllable worm self-locking and anti-loosening fine-tuning fixture for workpiece clamping. Background technique [0002] In the machinery manufacturing industry, machine tools are used to process various workpieces, and clamping tools are required to fix the workpieces during processing, so as to realize cutting processes such as outer circle, end face, thread and axial cutting. For parts with low machining accuracy, it can generally be adjusted directly on the machine table to realize positioning and clamping, and then the position of the part can be determined by setting the machining coordinate system. For workpieces that require high machining accuracy, the relative position of the workpiece and the turning tool must be repeatedly checked, so the positioning accuracy must be increased. At the same time, ordinary clamps cannot be fine-tuned, which makes i...
