Abstract

The invention discloses a pressure-controllable high-precision fine-tuning clamp which belongs to the field of clamps. The clamp comprises a clamp base, a left fixing block, a left screw rod, a left clamping block, a right clamping block, a guide rod, a right fixing block as well as a driven connecting rod, a left spring, a driving connecting rod, a right spring, a transmission rod, a right screw rod, a handle and a scale disc, wherein one end of the driven connecting rod is hinged to the clamp base; the other end of the driven connecting rod is connected with the driving connecting rod through the transmission rod; one end of the driven connecting rod close to a chain is connected with the guide rod; the scale disc is arranged on the handle. The clamp solves the problems that a conventional clamp cannot be turned finely, the clamping force is difficult to control and the positioning precision is not high, and has the advantages of simple structure, reasonable design and easiness in manufacturing.

Description

technical field [0001] The invention belongs to the field of fixtures, and more specifically relates to a pressure-controllable high-precision 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 it difficult to control...
