Abstract
The utility model discloses an expansion rounding disc for machining. The expansion rounding disc consists of two pieces of expansion rounding discs and adjusting screw rods. Each expansion rounding disc consists of a semicircular support ring and a support frame. The expansion rounding disc is characterized in that each piece of expansion rounding disc has an integral structure, and is formed by welding the semicircular support ring and the support frame, and two adjusting nuts are arranged on a cross rod of the support frame, and are provided with left hand or right hand threads; each adjusting screw rod has an integral structure, and right hand or left hand threads opposite to those of the adjusting nuts are arranged at the two ends of the adjusting screw rods; the middle section of each adjusting screw rod has a square cross section; the two pieces of expansion rounding discs are assembled and connected through the adjusting screw rods and the adjusting nuts; each semicircular support ring has a U-shaped cross section; and the adjusting screw rods are required to be thermally refined. The expansion rounding disc is simple in structure, firm, durable and easy to machine and use, and a large-diameter cylinder ring machining or assembling task can be easily and efficiently finished with high quality.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of machining with the disk that expands.
Background technology
In field of machining, shell ring is made in the manufacturing of most of cylindrical vessels usually earlier, and shell ring is rolled into tubular by sheet material and welds, and shell ring is welded into stack shell again, welds end socket or cover plate then.Shell ring is when diameter is big, and its rigidity is not fine, can not finely keep shell ring circularity, if do not adopt frock, then is difficult to operation during welding, and welding work efficiency and welding quality will be had a greatly reduced quality.Also having a kind of situation is exactly that blower fan is made the field, makes pilot hole on the ring flange that major diameter air duct welding flange or air duct flange form, if there is not suitable frock, then can not guarantee the circularity of air duct, guarantees the high-quality and high-efficiency that welds, assembles.
Summary of the invention
The novel purpose of this reality is exactly a kind of high-quality and high-efficiency frock that puts forward to the manufacturing of major diameter cylindrical device and assembling, is specially a kind of machining with the disk that expands.
The utility model is made up of bloated disk of two slit bamboo or chopped woods and adjusting screw(rod), and the disk that expands is made up of semicircle support ring and support, it is characterized in that the bloated disk of each slit bamboo or chopped wood is an integral structure; Be welded by semicircle support ring and support, the support cross bar is established two adjusting nuts, and adjusting nut is established left-handed or dextrorotation spiral shell mosquito; Adjusting screw(rod) is an integral structure; The corresponding adjusting nut in two ends is established dextrorotation or left hand thread, and adjusting screw(rod) interlude cross section is square, and two slit bamboo or chopped woods are expanded disk through adjusting screw(rod) and adjusting nut assembling connection.
Said semicircle support ring cross section is a U-shaped.
Said adjusting screw(rod) needs through modifier treatment.
During use, the utility model places in the workpiece tube circle of to be processed or assembling, spanner clamping adjusting screw(rod) interlude, or clockwise or be rotated counterclockwise adjusting screw(rod) the disk that expands is strutted.Because the utility model has suitable rigidity, can guarantee the dimensional stability of following process or assembling.After processing or assembling are accomplished, as long as rightabout rotation adjusting screw rod just can be removed the utility model very easily.
The utility model beneficial effect is: simple in structure, durable, processing and fabricating and use easily is easy to realize the high-quality and high-efficiency completion of processing of major diameter tube circle or fittage.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that Figure 1A-A is to the view sketch map.
Fig. 3 is the adjusting screw(rod) structural representation.
Fig. 4 is that Fig. 3 C-C is to the view sketch map.
Among the figure, the semicircle support ring of 1-, 2-support, 3-adjusting nut, 4-adjusting screw(rod).
The specific embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model specific embodiment is explained as follows:
A kind of machining is made up of bloated disk of two slit bamboo or chopped woods and adjusting screw(rod) 4 with the disk that expands, and the disk that expands is made up of with support 2 semicircle support ring 1; It is characterized in that the bloated disk of each slit bamboo or chopped wood is an integral structure; Be welded with support 2 by semicircle support ring 1, support 2 cross bars are established two adjusting nuts 3, and adjusting nut 3 is established left-handed or dextrorotation spiral shell mosquito; Adjusting screw(rod) 4 is an integral structure; The corresponding adjusting nut in two ends is established dextrorotation or left hand thread, and adjusting screw(rod) 4 interlude cross sections are square, and two slit bamboo or chopped woods are expanded disk through adjusting nut 3 and adjusting screw(rod) 4 assembling connections.
Said semicircle support ring 1 cross section is a U-shaped.
Said adjusting screw(rod) 4 needs through modifier treatment.
During use, the utility model places in the workpiece of to be processed or assembling, spanner clamping adjusting screw(rod) 4 interludes, or clockwise or be rotated counterclockwise adjusting screw(rod) 4 disk that expands is strutted.Because the utility model has suitable rigidity, can guarantee the dimensional stability of following process or assembling.After processing or assembling are accomplished, as long as rightabout rotation adjusting screw rod 4 just can be removed the utility model very easily.
The utility model is simple in structure, and is durable, and processing and fabricating and use easily is easy to realize the high-quality and high-efficiency completion of processing of major diameter tube circle or fittage.
