Double-spindle symmetrical type grinding machining device

Abstract

The invention relates to the technical field of grinding machining, in particular to a double-spindle symmetrical type grinding machining device. The device comprises a machining bottom groove seat, a supporting frame, a bottom clamping seat, a lifting rod, an opposite movement fixing assembly and the like. The supporting frame is fixedly installed on the top face of the machining bottom groove seat, the bottom clamping seat is fixedly installed in the middle of the top face of the machining bottom groove seat, the lifting rod is slidably connected to the supporting frame, and the opposite movement fixing assembly is slidably connected to the bottom clamping seat. A worker can control the positions of an external movable connecting piece and devices on the external movable connecting piece according to the machining requirement of a workpiece, so that the positions of a first machining wheel and a second machining wheel are changed, and the first machining wheel and the second machining wheel can sufficiently grind the surfaces of the two sides of the workpiece; and therefore, the device can be used for grinding workpieces of different specifications, and has universality.

Description

Technical field [0001] The present invention relates to a grinding technology, and in particular relates to a symmetric two-spindle grinding apparatus. Background technique [0002] Grinding is a mechanical processing method of removing material, refers to abrasive, abrasive cutting method of the workpiece, the excess material in the grinding machine used widely in the manufacturing industry, it is one of material removal methods, the grinding under finishing machining, less processed, high precision, is quite common to use a jig grinder in the current mold processing. [0003] The current angle grinder grinding which are fixed, and the jig grinder is set dead angle, thus causing only a processing jig grinder with the specifications of the workpiece, does not have a universal, and for some mold workpiece, such as a crankshaft connecting rod, usually double-sided surface grinding process ends thereof, such parts require grinding sequentially performed on a plurality of specific pr...

AI Technical Summary

Problems solved by technology

[0003] The grinding angle of the current grinding machine is fixed, and the angle of the grinding machine fixture is also fixed, so a pair of grinding machine fixture can only process workpieces of the same specification, which is not universal, and for some molds Workpieces, such as crankshaft connecting rods, usually need to be ground on both sides of the surface. Grinding such workpieces needs to be carried out sequentially on multiple grinding machine fixtures with specific processing angles. Obviously, the grinding process of this kind of grinding machine fixtures The work efficiency is low and the processing cost is high

[0004] In the prior art, although there are grinding machine fixtures, there is no device that can simultaneously realize that a pair of grinding machine fixtures can be applied to workpieces of multiple specifications, which means that the existing grinding machine fixtures can no longer meet the production needs. Therefore, it is necessary to address The disadvantage of the existing technology is to design a dual-spindle symmetrical grinding device that can grind workpieces of different specifications and can fully grind multiple specific processing angles of the workpiece
