Auxiliary positioning device

Abstract

The invention provides an auxiliary positioning device. The auxiliary positioning device comprises a drilling sleeve, a mandrel, a nut, a support plate, a bracket, a fixed plate, an adjustable bracket, a cross beam, a screw rod, a handle, an elastic thrust rod, a spring and a dowel pin column; the drilling sleeve is assembled in the fixed plate; the bracket is mounted on the lower side of the fixed plate; the mandrel is arranged on the right side of the bracket; the nut is assembled on the annular side surface of the mandrel; the support plate is assembled on the annular side surface of the mandrel; the adjustable bracket is arranged on the back side of the bracket; the cross beam is fixed on the outer surface of the adjustable bracket; the screw rod is mounted on the annular side surfaceof the cross beam; the handle is assembled in the screw rod; the elastic thrust rod is mounted on the front end surface of the bracket; the spring is arranged on the back side of the elastic thrust rod; and the dowel pin column is assembled on the back end surface of the bracket. Through the design, the problems of low workpiece clamping rigidity and influence on the workpiece machining quality ina traditional auxiliary positioning device are solved; and the auxiliary positioning device is reasonable in structure and convenient to combine and install, can realize auxiliary supporting of workpieces in two perpendicular directions to preferably improve the workpiece clamping rigidity, and reduces the vibration and movement probability in the workpiece machining process to achieve excellentauxiliary machining effect.

Description

technical field [0001] The invention is an auxiliary positioning device, which belongs to the technical field of auxiliary positioning tools. Background technique [0002] When the workpiece is processed, it is required that the action point of the clamping force should be as close as possible to the workpiece, which can prevent the workpiece from vibrating and deforming, and improve the stability and reliability of positioning. If it cannot be done, it is necessary to add an auxiliary support close to the workpiece processing surface to increase the clamping stiffness, and an auxiliary positioning device is required for processing the workpiece. [0003] In the prior art, the support of the existing auxiliary positioning device can only support in a single direction, resulting in low clamping stiffness of the workpiece, which affects the quality of the workpiece manufactured. An auxiliary positioning device is urgently needed to solve the above-mentioned problems. Content...
