Description
Technical field
The utility model belongs to pressure-measuring instrument technical field, and in particular to a kind of spiral Bourdon tube winding clamp.
Background technique
Spiral Bourdon tube is common sensing element in pressure gauge, and structural schematic diagram is as shown in Figure 1, it is a kind of tube body
Twist and section is specific shape, and the elastic sensing element of pressure is measured using the bending change of pipe or torsional deflection,
It is widely used.At present when manufacturing spiral Bourdon tube, first lap will appear the not round and smooth situation of coiling fillet, cause in spiral shell
Rotation Bourdon tube will appear the danger of rupture when by pressure, therefore be badly in need of designing a kind of spiral Bourdon tube winding clamp, solve around
The not round and smooth problem in rounding angle.
Summary of the invention
The purpose of this utility model is: providing a kind of spiral Bourdon tube winding clamp, solves the not round and smooth skill of coiling fillet
Art problem.
To solve this technical problem, the technical solution of the utility model is:
A kind of spiral Bourdon tube winding clamp, including collet pedestal 1, collet 2 and collet plug 3；
The collet pedestal 1 generally cylindrical body, bottom end have the installation screw thread cooperated with tooling, and middle-end is with notch
Spanner position, upper end is half boss structure of coiling, and rounded corner is used to install Bourdon tube one end when coiling；
The collet 2 is barrel-like structure, the major diameter fit of internal diameter and collet plug 3, with tapped through hole on lateral wall；
The collet plug 3 generally cylindrical body, diameter is identical as the diameter of collet pedestal 1, and one end is half boss structure；
The fixture further includes screw 4, and the screw 4 is adapted with the tapped through hole of collet 2, and passing through screw 4 will
Collet pedestal 1, collet 2 and collet plug 3 are fixed together.
The rounding radii range of the collet pedestal 1 are as follows: R1mm~R2mm.
The spanner position of the collet pedestal 1 is Step Shaft.
The collet pedestal 1 is stainless steel material.
The collet 2 is copper product or copper alloy.
The collet plug 3 is stainless steel material.
The beneficial effects of the utility model are: the spiral Bourdon tube of the utility model spiral Bourdon tube winding clamp coiling
One circle coiling fillet is round and smooth, solves the problems, such as that spiral Bourdon tube ruptures when by pressure.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples:
Please refer to shown in Fig. 1, Fig. 3 and Fig. 4, a kind of spiral Bourdon tube winding clamp comprising collet pedestal 1, folder
First 2 and collet plug 3, wherein the pedestal 1 is stainless steel material, and bottom end is with installation screw thread, for being mounted on winding tool
On, middle-end is the spanner position with notch, and upper end is half boss structure of coiling, and rounded corner is used for installation kit when coiling
End pipe Single port.The collet 2 is copper product or copper alloy, and outer surface carries out chromium plating process, and one end has threaded hole, for pacifying
Cartridge screw.The collet plug 3 is stainless steel material, and one end is half boss structure, is used to install 6 one end of Bourdon tube when coiling.Bottom
It is fastened between seat 1 and collet 2 by screw, when coiling spiral Bourdon tube 6, by Bourdon tube blank one end insertion collet 2, then
It is inserted into collet plug 3, screw is tightened and carries out coiling.
Please refer to Fig. 4 and Fig. 5, the collet pedestal 1 of the utility model as indicated, processed by stainless steel bar 1Cr18Ni9Ti and
At cylindrical-shaped structure, bottom interface be M8 × 1-6h screw thread, length 7mm, middle-end be the spanner position with notch, be used for
The position of spanner is twisted, upper end is half boss cylindrical structure, and is rounded down, after fillet size controls 6 coiling of Bourdon tube
Fillet guarantees 6 first lap rounding off of Bourdon tube；
Referring to Fig. 3, the hollow cylindrical knot that the collet 2 of the utility model is process using ledrite HPb59-1 stick
Structure has the threaded hole of M3 at the 4mm of one end end face, is used for collet pedestal, the fastening between collet plug and collet.
Referring to Fig. 3, the cylindric knot that the collet plug 3 of the utility model is process by stainless steel bar 1Cr18Ni9Ti
Structure, one end are half boss structure, are used to install 6 one end of Bourdon tube when coiling.
In order to easy to process, in process, collet plug 3 is cut after being integrally machined with collet pedestal 1, and outer diameter is identical,
