Embodiment 1

[0037] A guide device for a servo, comprising a connecting piece 7 and a leaf spring guiding mechanism 6, the leaf spring guiding mechanism 6 is connected to the connecting piece 7, and the connecting piece 7 is used to fixedly connect the driving mechanism to the leaf spring guiding mechanism 6. The leaf spring guide mechanism 6 includes 4 sets of Z-shaped folded leaf springs 601, and the 4 sets of Z-shaped folded leaf springs 601 are arranged in the outer frame of the leaf spring, and the outer frame of the leaf spring is connected to the grating assembly. The 4 sets of The zigzag folded leaf springs 601 are arranged symmetrically to the center. In this embodiment, the four zigzag folded leaf springs 601 are arranged in a cross shape, which realizes the large displacement output performance of the guide mechanism and has a compact structure, saving the space of the machine tool. The folded leaf springs 601 are arranged symmetrically in a cross to ensure the load-bearing stiff...

Embodiment 2

[0046] The difference between embodiment 2 and embodiment 1 is that the outer frame of the leaf spring in embodiment 2 is a regular hexagon, and there are 6 leaf springs at this point, and the connecting piece 7 includes 6 rods, 6 rods The starting ends of each are connected to the central symmetrical point 602 of the six rods. The block is a hexagonal prism, and after enlarging the number of folded leaf springs 601, the redundancy of the entire guiding device is also improved.

Embodiment 3

[0048] Embodiment 3 discloses an ultra-long-stroke fast-knife servo, including the guide device for the servo, and also includes a driving mechanism, a grating assembly, a turning tool holder 201, and a fixing seat. The guiding device of the device is connected to the turning tool holder 201, the driving mechanism is arranged in the fixed seat, and the grating assembly is connected to the guiding device for the servo.

[0049] Further, the tool holder includes a tool seat, a turning knife and a press block 202, the tool seat is connected to the folding leaf spring 601, a turning knife is arranged on the tool seat, and the press block 202 is connected to the tool seat , the pressing block compresses the blade;

[0050] The knife pressing block 202 is provided with a wedge-shaped surface and a slotted hole to realize pressing the blade in the horizontal direction, and compress the blade in the vertical direction by adjusting the pressing bolt;

[0051] Further, the fixed seat i...

Abstract

The invention discloses a guiding device for a server and a superlong stroke fast tool server. The guiding device comprises a connecting piece and a plate spring guiding mechanism. The plate spring guiding mechanism is connected with the connecting piece. The connecting piece is used for fixedly connecting a driving mechanism to the plate spring guiding mechanism. The plate spring guiding mechanism comprises multiple Z-shaped folding plate springs. The multiple Z-shaped folding plate springs are arranged in a plate spring outer frame. The plate spring outer frame is connected with an optical grating assembly. The multiple Z-shaped folding plate springs are arranged in a manner of central symmetry. A block body is arranged at a central symmetry point of the multiple Z-shaped folding plate springs. By means of the plate spring guiding mechanism of the guiding device for the server, superlong stroke output of the fast tool server can be achieved; and meanwhile, the structural size is compact, and the fast tool server can be embedded into a fast tool servo machining tool conveniently.

Description

technical field [0001] The invention relates to a super-long-stroke fast-knife servo, in particular to a guide device for the servo and the super-long-stroke fast-knife servo. Background technique [0002] Fast tool servo technology is an effective method for processing complex curved surface parts. The mechanism installs a fast tool servo unit on the machine tool to drive the turning tool to reciprocate linearly along the radial or axial direction of the workpiece, thereby processing the non-circular section or non-axisymmetric surface of the part. . At present, in various fast-knife servo mechanisms, the fast-knife servo mechanism driven by piezoelectric ceramics has the problem of small stroke, which limits the application range of fast-knife servo machining; the fast-knife servo mechanism driven by voice coil motor has a large output stroke, but its The manufacturing cost of the air-floating guide rail used in the guiding mechanism is relatively high, and the air-floati...
