Problems solved by technology

The existing positioning tips have the following problems: 1) The positioning only depends on the matching of the back cone and the machine tool. During installation, it will inevitably cause the positioning tip to move slightly along the axial direction, thereby affecting its positioning accuracy; When the rear cone is fixed on the machine tool, the front cone is pressed against the part to be processed. Whether there is an installation error is difficult to realize by dialing the front cone; 3) When repeatedly installing and disassembling the positioning center, The fixing screws on the connecting flange will be loose, which will cause the positioning accuracy of the positioning center to decrease again in the subsequent use process.

Embodiment Construction

[0018] see figure 2 as well as image 3 , the present invention provides a high-precision positioning top. The high-precision positioning top includes a rear cone 1, a connecting positioning flange and a front cone 5; the rear cone 1 and the front cone 5 are on the same axis; the rear cone 1 is connected to the positioning flange It is connected with the front cone 5; the connecting positioning flange is provided with a top positioning end face 2; the axis of the rear cone is perpendicular to the line surface of the top positioning end face 2. The present invention modifies the traditional rear cone positioning to an over-positioning method in which the rear cone conical surface and the top positioning end face are combined to realize double positioning. Since the connecting and positioning flange is provided with the top positioning end face 2, on the one hand, the top can be repositioned, and on the other hand, the top can be connected with the machine tool to play a stabl...

Abstract

The invention belongs to the technical field of machining, and relates to a high-precision positioning center. The center comprises a rear cone, a connecting positioning flange and a front cone, wherein the rear cone and the front cone are located on the same axis, the rear cone is connected with the front cone through the connecting positioning flange, a center positioning end face is arranged onthe connecting positioning flange, and the axis where the rear cone is located is perpendicular to the line face of the center positioning end face. The high-precision positioning center has the advantages that the positioning precision is high, rapid fine adjustment can be realized, and rapid replacement can be realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to a top, in particular to a high-precision positioning top. Background technique [0002] As the power transmission part of the hydraulic transmission system, the gear shape on the transmission shaft (its structure is as follows figure 1 Shown) The machining accuracy directly affects the transmission accuracy and service life of the hydraulic pump. Gear hobbing is usually used for gear machining on the transmission shaft, but in the process of gear hobbing, as a positioning center for part processing, its positioning accuracy directly affects the machining accuracy of the tooth profile. In order to ensure the machining accuracy of the tooth profile, the It is necessary to repeatedly adjust the positioning top. At the same time, due to the unstable positioning of the general positioning center, it is necessary to check the positioning accuracy of the positioning center ...
