Quick clamping nut drilling bench

Abstract

The invention discloses a quick clamping nut drilling bench which comprises a base. A rear holder is arranged on the rear side of the base, a clamping platform is disposed at the end of the rear holder, and a front clamping device which is rotatable is arranged at the front end of the clamping platform. A side positioning screw is disposed in the middle of the rear holder, a pressing-up bolt is arranged in the middle of the clamping platform, and a workpiece placement assembly is disposed at the upper end of the base, at the position corresponding to the pressing-up bolt. The front clamping device which is rotatable is adopted, three sides of the base are open, an elastic workpiece-pressing shaft at the lower end of a rotatable workpiece-pressing plate presses against the front side of a workpiece, the side positioning screw presses against the rear side of the workpiece, the pressing-up bolt presses against the upper end of the workpiece, the lower end of the workpiece is installed on a rack positioning plate, and the clamping speed is fast. When the clamping process is finished, the rotatable workpiece-pressing plate is rotated to enable the elastic workpiece-pressing shaft to be fixed in a rotation positioning hole, and then the workpiece can be taken out easily. The quick clamping nut drilling bench has the advantages of high clamping speed, high detaching speed, and stable processing quality.

Description

technical field [0001] The invention relates to a nut drilling and clamping device, in particular to a fast clamping nut drilling platform. Background technique [0002] The steering screw nut pair of automobiles is an external circulation ball screw structure. The balls are circulated through two sets of conduits on the steering nut. The depth and position of the nut hole are high. At present, the traditional nut drilling and clamping device is a closed structure. ,Such as figure 1 As shown, the two sides of the entire clamping device are sealed with fixed plates, one of which is the workpiece pick-and-place opening. When the workpiece is placed in the frame, the fastening bolts 2 on the two fixed plates 1 fix the workpiece 3 before processing , This kind of nut drilling and clamping device takes time to take the workpiece, the iron filings are not easy to clean, the processing efficiency is low, and the quality is unstable.
