Abstract
The invention discloses a plug tray. The plug tray comprises a choke plug, at least three ribbed plates are arranged on the choke plug, a casing pipe is fixed on the left side of the choke plug, and at least three adjustable bolts are in a screwed connection with the pipe wall of the casing pipe. After the plug tray is optimized, the number of the adjustable bolts is changed to four, the adjustable bolts are uniformly distributed along the circumference of the casing pipe, the number of the ribbed plates is changed to four, the ribbed plates are uniformly distributed along the circumference of the choke plug, and the casing pipe and the ribbed plates are welded on the choke plug. The plug tray has the advantages that when wall thickness borrowing is performed on large hollow pipe parts, the operation is simple and safe, and the accuracy is high.
Description
Technical field
The present invention relates to the machine tools technical field, especially relate to a kind of stifled dish.
Background technology
Usually, borrow wall thickness, often use chuck adjustment workpiece and borrow wall thickness, or lean on the stifled dish of top execution to adjust workpiece and borrow wall thickness through the parallels skin for the large hollow pipe part.Such operation is difficulty comparatively all, and in the top process of loosening afterbody, causes part to come off accidentally easily, thereby injures the equipment guide rail by a crashing object or hurt sb.'s feelings.Simultaneously, such manipulation accuracy is not high.Therefore be necessary to improve.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide a kind of stifled dish, when it has the large hollow of carrying out pipe part by means of wall thickness, and simple to operate, safety, and the higher characteristics of precision.
To achieve these goals, the technical scheme that the present invention adopted is: stifled dish, comprise plug, and said plug is provided with at least 3 floors, and the left side of plug is fixed with sleeve pipe, is bolted with at least 3 adjustment bolts on the tube wall of sleeve pipe.
Said adjustment bolt is 4, and evenly distributes along the circumference of sleeve pipe.
Said floor is 4, and evenly distributes along the circumference of plug.
Said sleeve pipe, floor all are welded on the plug.
After adopting said structure, the present invention compares the advantage that is had with prior art and is: when carrying out the large hollow pipe part by means of wall thickness, and simple to operate, safety, and precision is higher.Stifled dish of the present invention is not only top to have carried out roof pressure to workpiece, and adjustment bolt and sleeve pipe all be positioned at interior, thereby has prevented coming off suddenly of workpiece, safer.Because the adjustment bolt can be adjusted the particular location of workpiece as the case may be, thus workpiece borrow the wall thickness centering accurately and comparatively simple.
Description of drawings
Fig. 1 is that the master of embodiments of the invention looks the sectional structure sketch map;
Fig. 2 is the left TV structure sketch map (containing workpiece) of Fig. 1;
Among the figure: 10, floor; 20, plug; 30, sleeve pipe; 40, adjustment bolt; 100, workpiece.
The specific embodiment
See illustrated in figures 1 and 2: stifled dish comprises plug 20.Plug 20 upper edge plugs 20 circumference are provided with at least 3 floors 10.Simultaneously, the left side of plug 20 is fixed with sleeve pipe 30, and the circumference of the tube wall upper edge tube wall of sleeve pipe 30 is bolted with at least 3 adjustment bolts 40.Optimize, adjustment bolt 40 is 4, and evenly distributes along the circumference of sleeve pipe 30.In like manner, floor 10 is 4, and evenly distributes along the circumference of plug 20.For the ease of preparation, sleeve pipe 30, floor 10 all can be fixed on the plug 20 through the mode of welding.
Among the present invention, plug 20 is used for and the top top tight workpiece 100 that cooperates of afterbody; Floor 10 is used to be fixed the tail end face of workpiece 100; Adjustment bolt 40 is used for according to the beat wall thickness difference of situation adjustment workpiece 100 of the wall thickness of workpiece 100 and cylindrical.
Concrete, workpiece 100 is enclosed within adjustment bolt 40 outsides, and tailstock centre holds out against plug 20 right-hand members, make four floors, 10 workpiece pressings, 100 tail end faces.Utilize the wall thickness appearance to beat wall thickness, and cross section symmetry 4 points.According to 4 adjustment of wall thickness situation adjustment bolts 40, take into account the workpiece 100 cylindricals situation of beating, make the thick point of wall thickness of workpiece 100 be adjusted into the high point of beating.Like this, make wall thickness difference comparatively even through adjustment, and drop in the claimed range, reach specification requirement.
Utilize stifled dish of the present invention to carry out the large hollow pipe part and borrow wall thickness, behind the centering workpiece 100, the final wall thickness difference of workpiece 100 is borrowed in the 0.15mm.
Claims (4)
1. stifled dish comprises plug (20), and it is characterized in that: said plug (20) is provided with at least 3 floors (10), and the left side of plug (20) is fixed with sleeve pipe (30), is bolted with at least 3 adjustment bolts (40) on the tube wall of sleeve pipe (30).
