Abstract
The utility model relates to a clamping apparatus and especially relates to a cylinder inner clamping apparatus which belongs to the welding mold field. Through one circular rigid support, a spiral pressing code with the adjustable length is arranged on a top. An internal diameter of a cylinder body is measured taking a center of the cylinder body as a reference. According to a measuring value, the length of the spiral pressing code is adjusted. If the measuring value is large, the length is shortened. If the measuring value is small, the length is increased. A roundness tolerance can be less than or equal to 2mm. The usage of the apparatus is simple and rapid. And required machining and assembling and welding size precision is guaranteed.
Description
Technical field
The utility model relates to a kind of jig, specifically relates to card device in a kind of cylinder, and it belongs to the weld mold field.
Background technology
Along with the continuous development of industry, the lathe industry is also in continuous development.Size and precision to mach cylinder all has very high requirement at present.Special when drum diameter is 4-5m, two terminations are respectively during machined, to circularity and justify tolerance grade such as beat very high requirement is arranged.But because behind the cylinder welding forming, its roundness tolerance is bigger, and the assurance of the roundness tolerance of large diameter cylinder is more difficult.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model is that a kind of card device in simple, convenient, the feasible cylinder that uses will be provided.
To achieve these goals, the technical scheme that utility model adopted is a card device in a kind of cylinder, it comprises support and spiral pressure sign indicating number, described support is the cylindrical shape rigid support, spiral pressure sign indicating number evenly is installed on the top circumference of support, and described spiral pressure sign indicating number is the spiral pressure sign indicating number of adjustable length.
Advantage of the present utility model is: by a Circular Rigid support, the top is equipped with the spiral pressure sign indicating number of adjustable length; It can be a benchmark with the cylindrical shell center, measures cylinder internal diameter; According to measured value, adjustable screw is pressed code length; If measured value is bigger than normal, then shorten length, if measured value is less than normal, then increase length; Can make roundness tolerance≤2mm; It has accomplished easy, quick, and has guaranteed desired machined and assembly welding dimensional accuracy.
Description of drawings
Fig. 1 is a front view of the present utility model;
Among the figure: 1, support, 2, spiral pressure sign indicating number.
The specific embodiment
In order further to understand card device in this cylinder, further specify below in conjunction with the accompanying drawing example.
It comprises support and spiral pressure sign indicating number, and described support is the cylindrical shape rigid support, and spiral pressure sign indicating number evenly is installed on the top circumference of support, and described spiral pressure sign indicating number is the spiral pressure sign indicating number of adjustable length.The use of described device; At first determine the Circular Rigid support, its diameter is less than cylinder internal diameter to be processed; This device is installed on two ends of cylindrical shell; Positioning, is benchmark with the cylindrical shell center, measures cylinder internal diameter; According to measured value, adjustable screw is pressed code length, if measured value is big, then shortens length; If measured value is little, then increase length; Adjusting repeatedly through being for 2-3 times makes roundness tolerance≤2mm, has arrived the requirement that machined has tolerance grade such as circularity and circle are beated.
Claims (1)
