Technical Field

The utility model belongs to the technical field of the digit control machine tool product processing frock, concretely relates to special fixture of blade disc class product.

Background

With the development of times, the industrial 4.0 intelligent manufacturing is in the way of being started, which also drives the different military prominence of the intelligent machine tool industry. To create an intelligent machine tool, high-end precise mechanical parts and parts are required to be manufactured and matched with the intelligent machine tool, and one of the mechanical parts, namely a cutter head, is important in realizing precise action of the machine tool. Due to the structural requirements, the rigidity of the part is very weak, the precision requirement is very high, and the clamping and processing speed is very low, so that the product is processed by using the traditional clamping method, the rejection rate is high, the production efficiency is low, the product cost is greatly improved, the mass production is difficult to enter, and the rapid popularization and production of the high-end intelligent machine tool are severely restricted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a special fixture of blade disc processing to cost, quality and the efficiency problem of proposing in solving above-mentioned background.

The utility model adopts the following technical scheme:

the utility model provides a special fixture of blade disc class product, anchor clamps include workstation, supporting shoe, first hexagon socket head cap screw, bottom plate, short clamp plate, second hexagon socket head cap screw, cushion, long clamp plate, adjustable brace, the bottom plate sets up to three, is 90 degrees circumference and distributes on the workstation, be equipped with the supporting shoe of height such as equal on the bottom plate, be equipped with short clamp plate on the supporting shoe, short clamp plate one end is pressed at the cushion, and the other end compresses tightly the work piece, be equipped with adjustable brace on the workstation, be equipped with long clamp plate on the adjustable brace, long clamp plate presses workstation circumference quartering distribution with three short clamp plate.

Furthermore, the bottom plate is fixedly connected with the workbench through a first inner hexagon screw.

Further, the short pressing plate is connected with the bottom plate through a second inner hexagon screw.

Further, the clamps are distributed in an axial symmetry mode.

The clamp is characterized in that: the original circumferential clamping is changed into pressing, three points are equal-height supports, and one point is an adjustable support, so that when the workpiece is pressed, the workpiece is in a stress balance state, and the clamping force does not generate deformation influence on the workpiece; after the workpiece is clamped, the workbench, the base plate, the supporting block, the pressing plate and the workpiece form an integral system, so that the rigidity of the workpiece is enhanced, the cutting deformation is reduced, and the processing speed of the workpiece is increased. The clamp has the advantages that the original process which is difficult to process is changed into the process which is simple to operate, the working hours are reduced, and the quality is improved.

The utility model discloses an advantage and effect do:

the problems that the process is difficult to process, the quality is difficult to control, the processing cost is high, and the processing time is long are solved. The fixture has the advantages that the workpiece processing speed is increased, the overall quality of the workpiece is improved, the single piece processing cost is reduced, meanwhile, the fixture is simple to operate, the skill level of clamping and processing of workers is reduced, the field operation is convenient and rapid, and the mass production of products is realized.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

A special fixture for numerical control machine tool products comprises: the device comprises a workbench 1, a supporting block 2, a first socket head cap screw 3, a bottom plate 4, a short pressing plate 5, a second socket head cap screw 6, a cushion block 7, a long pressing plate 8, an adjustable support 9 and the like. The bottom plate 4 is circumferentially distributed on the workbench 1 at 90 degrees and is fixedly connected with the workbench 1 through the first socket head cap screws 3, so that the workbench and the bottom plate are used as a whole to serve as a clamp foundation, which is also a foundation for reinforcing the rigidity of a workpiece; the supporting block 2 is fixed on the bottom plate 4 and is used as a fulcrum of the short pressing plate; the short pressing plate 5 is connected with the bottom plate 4 through the second socket head cap screw 6, one end of the short pressing plate is pressed on the cushion block 7 when the short pressing plate is used, and the other end of the short pressing plate is pressed on a workpiece; the long pressing plate 8 is connected with the workbench 1 and used for pressing a workpiece; the adjustable support 9 is positioned below the long pressure plate 8, and the lower end of the adjustable support is connected with the workbench 1 and used for supporting a workpiece.

When the device is used, a worker installs the three bottom plates on the workbench in a 90-degree manner, the bottom plates are just positioned under the workpiece machining reference surface, and after fastening, the plane of the support blocks on the flat bottom plate is turned once, so that the plane of the support blocks on the bottom plates is absolutely horizontal; a hoisting workpiece is horizontally placed on the three supporting blocks, so that three processing reference surfaces of the workpiece are completely contacted with the planes of the supporting blocks, the workpiece is aligned, the rotation center of the workpiece is superposed with the center of a machine tool workbench, a cushion block is installed, and a short pressing plate is pressed; and installing an adjustable support according to the position shown in the figure, enabling the adjustable support to just push against the workpiece without deforming the workpiece, installing a long pressing plate and fastening, and finishing the installation of the clamp.

The utility model provides a blade disc class work piece rigidity weak, the clamping yielding and the high problem of required precision, the design of anchor clamps has broken through traditional chuck and has pressed from both sides the clamping method that tightly perhaps four-point flat pad of circumference compressed tightly, and the bold adoption "three die one live" roof pressure work piece thinking and method make work piece dress card almost indeformable, have improved the machining precision of work piece greatly. Meanwhile, the clamp also keeps the improvement of the rigidity of the workpiece by the traditional clamping method, so that the deformation of the workpiece after processing is reduced to the minimum, and the quality requirement of the workpiece is completely ensured. The clamp has a simple integral structure, is convenient for workers to operate, can save clamping time and improve the working efficiency. In conclusion, the application of the clamp not only ensures the quality requirement of the workpiece, but also improves the processing efficiency of the workpiece, and realizes the low-cost mass production of the workpiece.
