An integrated drilling and grinding tool for precision machinery manufacturing

Abstract

The invention discloses an integrated drilling and grinding dual-purpose tool for manufacturing precision machinery. The integrated drilling and grinding dual-purpose tool for manufacturing precisionmachinery comprises a tool holder, wherein a double-sided spline ring is fixed on the lower wall of the tool holder; a drill bit is sleeved with the double-sided spline ring in a sliding mode in the up-down direction; an annular grinding head sleeves the double-sided spline ring; a conductive block is fixed at one end, close to the tool holder, of the drill bit; the conductive block and the tool holder are jointly and fixedly connected with a flexible inner pipe body; the grinding head and the tool holder are jointly and fixedly connected with a plurality of flexible outer pipe bodies; the tool holder is internally provided with communication cavities of which the number is the same as the number of the outer pipe bodies; and each communication cavity communicates with the outer pipe bodyat the corresponding position. The integrated drilling and grinding dual-purpose tool for manufacturing precision machinery has the advantages that the double-sided spline ring with splines on the inner wall and the outer wall is arranged, so that the drill bit and the grinding head synchronously rotate along with the double-sided spline ring when the double-sided spline ring rotates, the drill bit and the grinding head slide along the axial direction of the double-sided spline ring, and the purpose of comprehensively arranging the drill bit and the grinding head on one tool holder is achieved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an integrated drilling and grinding tool for precision machinery manufacturing. Background technique [0002] The machining process usually includes a drilling process and a grinding process. Commonly used machining equipment usually separates these two processes, making it impossible to combine the two operations. However, tool setting operations are required between drilling and grinding. , after the drilling is completed, the tool change and tool setting operation have no effect on the accuracy requirements of ordinary machinery, but in precision machinery, slight errors may cause the finished workpiece size to fail to meet the standard. For this reason, we propose a An integrated drilling and grinding dual-purpose tool for precision machinery manufacturing that can greatly improve the accuracy of drilling and grinding processes.
