Abstract
The utility model discloses an end positioning fixing device for machining a large-scale pipe die outer circle. The end positioning fixing device comprises a disc and is characterized in that a center hole is formed in the center of the disc; four fixed screws are evenly distributed on the periphery of the disc 1 in a threaded connection mode; the section, between every two adjacent fixed screws, of the periphery of the disc is provided with an adjusting screw in a threaded connection mode; the four adjusting screws are evenly distributed as well. The outer end of each fixed screw is provided with a chuck capable of freely rotating and the axial cross section of each chuck is in an L shape. The device is easy to fix, convenient to use and flexible in operation, steel plates do not need to be welded before machining, the plates do not need to be cut after machining, and damage to a pipe die body is reduced; it is guaranteed that the machining position is adjusted in time according to the actual situation of a lathe in the pipe die outer circle machining process, the frequency of rotation of a workpiece is reduced, machining time is saved, and the work efficiency and the yield of products are improved.
Description
Technical field
The utility model relates to a kind of lathe tool for machining large pipe die cylindrical, belongs to machining equipment technology field, specifically a kind of end device for positioning and securing of machining large pipe die cylindrical.
Background technology
Large-scale pipe die mainly refers to centrifugal ductile cast iron pipes, effective length can reach 6 meters, be generally used for feedwater, draining, coal gas is carried, elevated pressures is born in requirement, its main machined surface is cylindrical and endoporus, Excircle machining generally carries out on lathe, the one end that adds centrifugal ductile cast iron pipes in man-hour is fixed with chuck, the other end is because be hollow, so need to weld a plate on the endoporus of end, face punching is to fix with thimble onboard, because workpiece is oversize, central hole location needs very accurate, guarantee workpiece energy normal process, after machining, again iron plate is sliced off to reprocessing endoporus with burning torch.Its weak point is: processing time consuming effort, welding process also damages workpiece body.
Summary of the invention
It is a kind of easily fixing that the purpose of this utility model is to provide, easy to use, flexible operation, do not injure workpiece body, guarantee in the process of processing pipe die cylindrical, can adjust in time Working position according to lathe actual conditions, save process time, the end device for positioning and securing of the machining large pipe die cylindrical of increasing work efficiency.
In order to reach above object, the technical scheme that the utility model adopts is: the end device for positioning and securing of this kind of machining large pipe die cylindrical, comprise disk, it is characterized in that: the center at disk is provided with centre hole, on all edges of disk 1, be uniformly distributed and be provided with four standing screws that are threaded, on all edges of the disk between two adjacent standing screws, be provided with the adjusting screw(rod) being threaded, four adjusting screw(rod)s are also evenly laid, the outer end of standing screw is provided with the dop freely rotating, and the axial section of dop is " L " type.
Described disk is provided with equally distributed four through holes.
The beneficial effects of the utility model are: easily fixing, easy to use, flexible operation, not be used in the Plate Welding work of first being processed, and the steel plate after also need not machining cuts off work, has reduced the injury to pipe die body simultaneously; Guaranteed, in the process of processing pipe die cylindrical, can adjust in time Working position according to lathe actual conditions, reduced the number of times that workpiece spins, saved process time, improved the qualification rate of operating efficiency and product.
Accompanying drawing explanation
Fig. 1 is that structure master of the present utility model looks schematic diagram.
Fig. 2 is structure schematic rear view of the present utility model.
Fig. 3 is that the utility model is along the structure cross-sectional schematic of Figure 1A-A.
In figure: 1, disk; 2, through hole; 3, centre hole; 4, standing screw; 5, adjusting screw(rod); 6, dop.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, make the utility model.The end device for positioning and securing of this kind of machining large pipe die cylindrical, comprise disk 1, it is characterized in that: at the center of disk 1, be provided with centre hole 3, on all edges of disk 1, be uniformly distributed and be provided with four standing screws 4 that are threaded, on all edges of the disk 1 between two adjacent standing screws 4, be provided with the adjusting screw(rod) 5 being threaded, four adjusting screw(rod)s 5 are also evenly laid, and the outer end of standing screw 4 is provided with the dop 6 freely rotating, and the axial section of dop 6 is " L " type.
Described disk 1 is provided with equally distributed four through holes 2.
While using the utility model, first disk 1 is placed on to the endoporus place, end of centrifugal ductile cast iron pipes, rotate four standing screws 4, make each dop 6 extend out to tube wall place and be stuck in the outer end of tube wall, rotate again four adjusting screw(rod)s 5, four adjusting screw(rod)s 5 are all withstood on the inner wall of end of centrifugal ductile cast iron pipes, adjust the length of each adjusting screw(rod) 5, make centre hole 3 be positioned at the shaft core position of centrifugal ductile cast iron pipes, finally hang on lathe, with thimble, withstand on centre hole 3 interior fixing, timing, can regulate by four adjusting bolts 5 and four set bolts 4, need not rotate whole tube wall is recoverable, after Excircle machining completes, derotation bolt can be unloaded this device down, time saving and energy saving, improved operating efficiency.
