Reaming positioning clamping device

Abstract

The invention discloses a reaming locating clamping device which comprises a machine frame arranged below a vertical drill reamer, a work table for placing a workpiece to be machined is arranged above the machine frame, a through hole sharing the same central line with the reamer and a central hole of the workpiece to be machined is formed in the work table at the position right below the reamer, and a pressing mechanism for pressing the workpiece to be machined is arranged on the work table around the circumference of the through hole symmetrically. The pressing mechanism is a right angular rotary cylinder arranged on the work table through a cylinder support. A locating mechanism penetrating the through hole and used for locating the workpiece to be machined is arranged on a lower supporting plate fixedly arranged on the machine frame below the work table. The reaming locating clamping device can locate and press the workpiece to be machined on a drilling machine, an operation mode of reaming with the central hole of the workpiece to be machined as a reference is adopted, coincidence of axis of a central line of a hole reamed later and an original hole is guaranteed, and reaming precision is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of mechanical product processing, in particular to an auxiliary device used when processing the center hole reaming of a part. Background technique [0002] In the field of mechanical product processing technology, reaming the center hole of a part is one of the more extensive processes. The mechanical products that do not involve center hole reaming mainly include diamond saw blades, square parts, round parts or polygonal parts. Etc., these parts need to be reamed at the machining hole. The following takes the reaming process of the saw blade center hole as an example to describe the existing reaming process in detail. [0003] Diamond tool saw blades are commonly used tools for cutting marble and ceramic tiles in the construction industry. The conventional diamond saw blade reaming process adopts the floating reaming method of the substrate for processing. Specifically: first install a three-jaw chuck on the vert...

AI Technical Summary

Problems solved by technology

This process has the following disadvantages: 1) In the process of reaming, in order to ensure the stability of the saw blade, the three-jaw chuck needs to clamp the saw blade forcefully. Under the action of extrusion, the matrix is ​​easy to bow and deform, which further leads to the deformation of the center hole and affects the machining accuracy of the hole

2) Since the entire process requires two people to cooperate, there is idle time for the staff to wait during the process of loading and unloading the saw blade and reaming, resulting in unnecessary labor waste; in addition, there is a risk of uncoordinated cooperation between two people, which is easy to lead to industrial accidents
