Chamfer grinding device

Abstract

The invention discloses a chamfer grinding device. The chamfer grinding device comprises an L-shaped knife edge block, a fixing screw, a pressing rod, a pressing screw and a base. A kidney-shaped groove is formed in one end of the knife edge block, and a knife edge is arranged at the other end of the knife edge block. A V-shaped groove is formed in the clamping end face of the base, and a 60-degree angle is formed between the bottom end face of the base and the machining plane. The pressing rod presses a workpiece into the V-shaped groove of the base through the two pressing screws on the two sides, the knife edge end of the knife edge block is tightly attached to the groove face of the upper end of the workpiece, and the other end of the knife edge block is fixed to the base through the kidney-shaped groove and the fixing screw. A 90-degree V-shaped groove is formed in the clamping end face of the base. The 60-degree knife edge is arranged at the knife edge end of the knife edge block. The fixing screw is a hexagon socket head screw M5*12. The pressing screws are hexagon socket head screws M8*40. The chamfer grinding device is simple in structure and quick to install; machining accuracy requirements are guaranteed, machining procedures are simplified, and meanwhile the machining period is shortened; and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, and more specifically relates to a chamfering device for chamfering the notch of a rotating pin sleeve. Background technique [0002] Because of its high manufacturing precision and fast processing speed, CNC punching machines are widely used in the sheet metal industry. Although the shape and structure are simple, the requirements for size and shape and position tolerances are relatively high. If simple single-piece production is performed, the production efficiency is too low. Wide application . As an important part of the CNC punching machine, the rotary pin sleeve ensures the centering position accuracy of the upper and lower turntables. If the parts are not large, it is difficult to ensure monthly batch delivery, and the processing cost will be high. Therefore, it is necessary to need a Special devices to improve production efficiency and reduce processing costs. [0003] Processing...

Problems solved by technology

The effect of process adaptability has been poor. Over time, the accuracy of the machine tool spindle is also easy to cause damage.

[0005] At the same time, due to the large demand for this product and the long processing cycle, especially the CNC milling machine process of the machining center is more time-consuming, we have changed it to a precision flat small grinding machine for processing, and specially designed a set of grinding and chamfering devices
