Abstract
The utility model provides a clamp for processing a nozzle ring. A positioning boss matched with an inner hole of the nozzle ring is formed on a baseplate; a screw rod is arranged in the center of the boss, and passes through a central hole of a pressure plate mounted perpendicular to the screw rod; the two ends of the pressure plate can be compressed on the end surface of the inner hole of the nozzle ring; the top end of the screw rod can be screwed in a clamp nut for compressing the pressure plate; another positioning boss matched with the inner hole of the nozzle ring is formed on the underplate; another screw rods uniformly distributed at the outer circumference of the baseplate pass through the central hole of the another pressure plate mounted perpendicular to the another screw rods; and the top ends of the another screw rods can be screwed in another clamp nut for compressing the another pressure plate. The clamp has the advantages that the inner hole and the end surface are positioned, at the same time, the pressure plates are symmetrically distributed in an adjustable manner to guarantee the quality, the symmetrically distributed pressure plates compress the end surface, and the inner hole and the inner hole slot are subject to finish turning, so that force on all clamping elements is acted in the axial direction, the workpiece deformation is less, the efficiency and the rate of finished products are improved, the product quality is guaranteed, the production requirement is met, the structure is simple, and the operation is convenient.
Description
Technical field the utility model relates to a kind of dish type thin-wall workpiece nozzle ring fixture for processing.
In the technological design of background technology ND5 nozzle ring, main difficult point is that this product belongs to the dish type thin-wall workpiece, because workpiece is thinner, rigidity is relatively poor, adopt conventional cutting working method, be subjected to the influence of axial cutting force and thermal deformation, flexural deformation can appear in workpiece, be difficult to reach specification requirement, product percent of pass is extremely low.And this blank material is again smart casting profiled member, and cost is than higher, for guaranteeing the yield rate of product, in process, it is very necessary to design the effective fixture for processing of a cover, in production practices, done a lot of trials, the rigidity of thin wall work-piece is relatively poor, and stressed back easily produces distortion.Therefore, generally can not make clamping force vertically act on the thin-walled surface of poor rigidity, and should act on the end face or the side of thin-walled.If will then should under clamping point, make aiding support, clamp distortion so that reduce it as far as possible with the thin-walled surface as clamping surface with adjustable support.When the clamping element of design anchor clamps, should increase the contact-making surface between clamping element and workpiece clamping surface, make workpiece be pressed the surface stressed even, pressure reduces on the unit are, clamps distortion to reduce it.
The summary of the invention the purpose of this utility model is to overcome weak point in the prior art, the nozzle ring fixture for processing that provides a kind of clamping force vertically to act on the nozzle ring end face.The structure of this nozzle ring fixture for processing is: base plate is provided with the positioning boss that matches with the nozzle ring endoporus, the center of boss is provided with screw rod, screw rod passes the centre bore that is vertically arranged pressing plate with it, the two ends of pressing plate can be pressed on the end face of nozzle ring endoporus, the top of screw rod can be screwed into the clamp nut of clamping platen, the location processes outer hole end surface and outer hole thereof after clamping; The screw rod that is distributed on the base plate excircle passes the centre bore that is vertically arranged pressing plate with it, and the top of screw rod can be screwed into the clamp nut of clamping platen, after the location clamps, and hole end surface and endoporus thereof in the processing.After the outer hole of this side and endoporus machined, with the endoporus location of this side, the outer hole and the endoporus of reprocessing another side were finished the processing of whole work-piece.Add man-hour carrying out finish turning, on base plate, with workpiece endoporus and end face location thereof, the processing of base plate is to perpendicularity with clamping workpiece, and position required precisions such as flatness are higher, and it is high that the endoporus quality of fit of the boss of base plate and workpiece is wanted, with the assurance positioning accuracy.
The utility model has the advantages that: by practice, our design specialized anchor clamps adopt endoporus and end face location, but are symmetrically distributed with regulator board simultaneously, to ensure the quality of products.Compress end face with the pressing plate symmetrical distribution, finish turning endoporus and interior hole slot size, the power of all like this clamping elements all acts in the axial direction, and workpiece deformation is less, raises the efficiency and yield rate, guarantees the quality of product, satisfies the requirement of production.The utility model nozzle ring fixture for processing is simple in structure, and is easy to operate.
