Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with accompanying drawings and examples. A passive damping fixture for milling processing, the schematic diagram of its processing application is as follows figure 1 shown. The passive damping fixture for milling processing is fixed on the workbench of the machine tool, the weakly rigid part to be processed is fixed on the fixture, and then the tool cuts the part.

[0029] The invention relates to a passive damping fixture used for milling of weak rigid parts. like figure 2 As shown, the device is composed of a base 1, a support member 2, a rotating member 3, a support adjustment member 4, a workbench 5, a support block 6, an adjustment plate 7 and corresponding screws, bolts and nuts. When using the device, first fix the base 1 on the machine table, and then fix the support 2 with the base 1 with screws, as figure 2 and Figure 4 The positions of middle parts 1 and 2 are shown. Put t...

Abstract

A milling passive vibration reduction clamp is composed of a base, a supporting piece, a rotating piece, a supporting adjusting piece, a working table, supporting blocks, an adjusting plate, corresponding screws and corresponding nuts. The base is fixed to the machine table, the supporting piece is connected with the base through the screws, the supporting block is located on the supporting piece, three cantilever beam type supports are evenly distributed on the rotating piece in a horizontal plane and arranged on the three supporting blocks respectively, and the bolts sequentially penetrate through the rotating piece, the supporting blocks and the supporting piece for fixing. The milling passive vibration reduction clamp is characterized in that based on the passive control principle, rigidity adjustment in three orthogonal directions is achieved in a mechanical adjustment mode, vibration of rigid parts in the numerical control milling process is reduced, and efficient and high-precision machining is achieved. Rigidity adjustment in any direction can be independently conducted without affecting rigidity adjustment in other directions, the adjustable parameter range is large, and machining requirements of various parts can be met. The milling passive vibration reduction clamp is easy to implement and maintain and free of environmental pollution.

Description

technical field [0001] The invention relates to a passive vibration damping fixture for numerically controlled milling of weakly rigid parts, in particular to a vibration damping device in the process of metal numerically controlled milling, so as to realize high-performance milling of weakly rigid metal parts and improve the performance of weakly rigid parts. processing accuracy and efficiency. The utility model relates to a fixture device belonging to the field of mechanical processing. Background technique [0002] With the rapid development of modern manufacturing industry, weakly rigid parts are increasingly widely used in the production and application of military and civilian products, and the requirements for their processing quality are also getting higher and higher. Due to poor rigidity, weakly rigid parts are prone to deformation and vibration under the influence of cutting force during processing, which affects processing accuracy and efficiency. In response t...
