Embodiment 1

[0022] Refer to attached figure 1 to attach image 3 The shown clamping device for milling of ring parts includes a turntable 1 and 32 positioning units arranged circularly on the turntable 1, each positioning unit includes a contour block 2 and a The positioning mechanism on the cushion block 2, the positioning mechanism includes an adjustment support seat 3 fixedly connected with the contour block 2 and a radial positioning assembly for radially positioning the workpiece 15 arranged on the adjustment support seat 3 and for An axial pressing assembly for axially pressing the workpiece 15 . In order to facilitate the adjustment of the radial pressure of the radial positioning assembly on the workpiece 15, the radial positioning assembly includes a first adjustment bolt 4 passing through the adjustment support block horizontally and a radial adjustment block arranged at the end of the first adjustment bolt 4 5. The first adjusting bolt 4 is threadedly matched with the adjusti...

Embodiment 2

[0024] In the aforementioned solution, in order to make the radial adjustment block 5 move forward and backward along the direction of the first screw when the first adjustment bolt 4 rotates, and at the same time the radial adjustment block 5 will not follow the first screw to rotate, avoiding the radial adjustment block 5 Friction with the workpiece 15, the end of the first adjusting bolt 4 is provided with an annular groove 6, the radial adjustment block 5 is provided with a stop screw 7 corresponding to the annular groove 6, and the end of the stop screw 7 extends to the ring In the slot 6 , the first adjusting bolt 4 can freely rotate relative to the radial adjusting block 5 . Further, in order to prevent the radial adjustment block 5 from causing damage to the surface of the workpiece 15 when pressing the workpiece 15, the radial adjustment block 5 is made of soft metal, and usually the radial adjustment block 5 is made of copper Yes, in order to increase the contact sur...

Embodiment 3

[0026] On the basis of Embodiment 1, in order to enable the axial compression assembly to perform good axial positioning on the workpiece 15, the axial compression assembly includes a second adjustment bolt 8 arranged on the adjustment support block, and The axial pressure plate 16 with which the second adjustment bolt 8 is threaded and the third adjustment bolt 9 arranged at the outer end of the axial pressure plate 16, the third adjustment bolt 9 is threaded with the axial pressure plate 16, and the second adjustment bolt 8 is provided with The lock nut 10, the second adjusting bolt 8, the third adjusting bolt 9 and the axial pressure plate 16 are combined into a lever mechanism, and the pressing force on the workpiece 15 can be realized by adjusting the second adjusting bolt 8 and the third adjusting bolt 9, The contact between the adjustment bolt and the workpiece 15 is avoided, and the damage to the workpiece 15 is minimized. Further, in order to avoid damage to the surfa...

Abstract

The invention discloses a clamping device for ring-like parts in milling. The clamping device comprises a rotary table and a plurality of positioning units; the plurality of positioning units are arranged on the rotary table in a circle manner; each positioning unit comprises an equal-height cushion and a positioning mechanism arranged on the equal-height cushion; the positioning mechanism comprises an adjusting support seat fixedly connected with the equal-height cushion, a radial positioning component for radially positioning a workpiece and an axial compacting component for axially compacting the workpiece; and the radial positioning component is arranged on the adjusting support seat. According to the invention, the clamping device for the ring-like parts in the milling can eliminate vibration caused by the milling on the workpiece, thereby improving the milling quality and precision of the workpiece.

Description

technical field [0001] The invention relates to the field of metallurgical machinery industry, in particular to a tool for clamping workpieces when ring parts are milled. Background technique [0002] Many important parts of wind power products are ring parts, which have complex structural shapes, high precision requirements, poor rigidity, large machining allowance, and poor manufacturability, and are prone to machining deformation and cutting vibration, resulting in machining errors. Such parts can generally only be processed on high-performance high-speed machining centers because of their high spindle speed, high spindle power and torque, fast feed speed and acceleration, high machine rigidity and precise motion control. Under these two extreme conditions, how to ensure the accuracy of the machine tool and the effective use of processing efficiency and ensure the processing accuracy and surface quality of parts has always been a research topic. Generally, after a high-p...
