Workpiece machining tool

Abstract

The invention discloses a workpiece machining tool. The workpiece machining tool comprises a base plate, at least one machining station is arranged on the base plate, the machining stations comprise clamping plates and driving mechanisms, the base plate is provided with mounting grooves in an up-down penetrating mode, one sides of the mounting grooves are provided with openings, clamping plates are arranged on the opening sides of the mounting grooves, and the clamping plates are arranged on the base plate in a sliding mode; and the driving mechanisms are arranged on the base plate, moreover,the driving mechanisms drive the clamping plates to slide in the mounting grooves in a reciprocating mode, and the clamping plates and the mounting grooves form closed-loop clamping and positioning holes. The workpiece machining tool can stably clamp workpieces, the influence of an elastic knife is reduced, and the machining precision and the machining efficiency are ensured.

Description

technical field [0001] The invention belongs to the field of machining tooling, in particular to a tooling for machining workpieces. Background technique [0002] as attached figure 1 As shown, a rough-machined workpiece in the shape of an "I" includes a shaft body 1b and ring-shaped end plates 1a and 1c integrally arranged at both ends of the shaft body 1b. The two ring-shaped end plates contain a plurality of Processing features, such as shape processing, outer contour processing, milling notch and drilling, etc., the existing processing tooling uses a boss-shaped cylindrical structure, and the protruding boss part is pierced in the shaft body 1b. Then one of the ring-shaped end plates is fixed by means of a pressure plate and locking screws, and then the other end plate is milled. Although the processing tooling of this method is simple, but because the end plate to be processed is less supported by force, it causes its clamping Unstable, prone to tool vibration and bou...

[0002] as attached figure 1 As shown, a rough-machined workpiece in the shape of an "I" includes a shaft body 1b and ring-shaped end plates 1a and 1c integrally arranged at both ends of the shaft body 1b. The two ring-shaped end plates contain a plurality of Processing features, such as shape processing, outer contour processing, milling notch and drilling, etc., the existing processing tooling uses a boss-shaped cylindrical structure, and the protruding boss part is pierced in the shaft body 1b. Then one of the ring-shaped end plates is fixed by means of a pressure plate and locking screws, and then the other end plate is milled. Although the processing tooling of this method is simple, but because the end plate to be processed is less supported by force, it causes its clamping Unstable, prone to tool vibration and bounce during processing, affecting the appearance of the workpiece, and it is not easy to ensure the dimensional accuracy of the workpiece, and even needs to be reworked continuously with empty tools, and in order to reduce the impact of the bounce tool, it is necessary to reduce the cutting speed, indirect The impact of the overall processing speed, resulting in reduced efficiency
