Detailed description of the invention
Embodiment, as Figure 1-3, gas turbine bearing block coarse-fine car special purpose device, including base 1, just to pressing plate 2, side pressure
Plate 5, equal height cushion block 4, balancing weight 6 and hexagon socket head cap screw.
Base 1 provides platform for bearing block M to be processed and frock, and rigidity is enough, it is possible to reduce the change of bearing block M to be processed
Shape；During centering, it is only necessary to the direction coordinate regulating bearing block M to be processed is the most permissible, improve the efficiency of clamping centering.
Base 1 is disc-shaped base, and side guide 5 is fixedly connected in the card of base 1 near the outer peripheral position of card,
The quantity of side guide 5 is two, and two side guides 5 are arranged along the axisymmetrical of base 1.
Each side guide 5 includes two the first right angle pressing plates 7 being oppositely arranged, fixing between two the first right angle pressing plates 7
Connecting and have the first horizontal pressing plate 8, the first right angle pressing plate 7 is fixing with base 1 to be connected, and described first right angle pressing plate 7 and first is horizontal
The hexagon socket head cap screw for compressing bearing block M to be processed it is equipped with on pressing plate 8.
The effect of side guide 5 is to prevent from processing bearing block M to rotate in a circumferential direction in the course of processing, resists bearing to be processed
Centrifugal force in a lateral direction in seat M rotary course, reduces the deformation of workpiece M.During installation, processing bearing block M is arranged on
Between two side guides 5, two the first right angle pressing plates 7 are positioned at the boss A both sides of bearing block M to be processed, before Workpiece clamping, and can
By the hexagon socket head cap screw on side guide 5, workpiece is finely adjusted.
Described just pressing plate 2 is being arranged on base 1 near the outer peripheral position of base 1, just pressing plate 2 is being included two second
Right angle pressing plate 3, is fixedly connected with the second horizontal pressing plate 9 between two the second right angle pressing plates 3, the second right angle pressing plate 3 and second is horizontal
The hexagon socket head cap screw adding clamping of workpieces it is respectively provided with on pressing plate 9.
The just effect to pressing plate 2 is to prevent bearing block M to be processed from rotating in a circumferential direction in the course of processing, resists to be processed
In bearing block M rotary course at positive the other side centrifugal force upwards, reduce the deformation of bearing block M to be processed.During installation, to be processed
The rear side boss B of bearing block M is placed between two the second right angle pressing plates 3, clamps at the rear side boss B of bearing block M to be processed
Before, just workpiece can be finely adjusted by the hexagon socket head cap screw on pressing plate 2 by this.
Just pressing plate 2 and side guide 5 are being distributed in the outermost of bearing block.Side guide 5 is symmetric, and position is to be processed
Bearing block M split radial dimension maximum, side guide 5 is at vertical radial direction maximum position, it is achieved treat processing in periphery
The regulation of bearing block M, tightly-pressing function.
Described balancing weight 6 is arranged on base 1 and just relative to pressing plate 2 side.
The balancing weight 6 effect by equilibrium centrifugation power, makes whole system including bearing block M to be processed and clamps
Position of centre of gravity and workbench the centre of gyration overlap, control centrifugal force, prevent the change in size after work pieces process.
Base 1 is provided with equal height cushion block 4, is first put down by equal height cushion block 4 car, it is possible to reduce the dress of frock clamp before processing workpiece
Join error, beneficially clamping centering and fine setting.
Processing unit (plant) use work flow is:
1. will clamp in advance in frock integral hoisting to workbench, frock equal height cushion block supports；
2. being lifted in frock and tighten screw by bearing block M to be processed, bearing block M to be processed is with contour pad
Block 4 supports；
3. with just to pressing plate 2 and side guide 5 by Work-sheet pressing on bearing block M to be processed, note the size of thrust, it is impossible to draw
Play workpiece deformation；
4. lathe centering, the adjustable claw that workbench is fixed in regulation and the screw jack being positioned under base,
By the axis of bearing block M to be processed and work table rotation center superposition.
