Abstract
The invention discloses a welding jig of spring pipes. The welding jig is provided with a welding base and is characterized in that the welding base comprises a spring-pipe base and a pressure joint pipe base; the welding base is fixed on a working platform surface; and the bottom surface of the welding base is connected with a motor by a rotating shaft. The welding jig has the advantages that the welding jig is driven to rotate by using the motor, so that manual welding displacement is avoided in the welding process, the welding accuracy is effectively controlled, the operating errors are reduced and the accuracy is greatly increased.
Description
Technical field
The present invention relates to a kind of welding fixture, specifically is a kind of tool of the C of being mainly used in type bourdon tube welding.
Background technology
Bourdon tube is the special forming pipe of end sealing, when bearing different pressures in the pipe and outside the pipe, then in its elastic limit, produces distortion.Bourdon tube is a kind of pressure detecting element in the pressure measuring instruments.It is the hollow tube made from elastomeric material that curves shapes such as C shape, spirality or disc spring shape.Bourdon tube the earliest curves C shape, because Frenchman E. bowden is invented, so claim Bourdon tube again, the modern times still widely apply, and its free end is removable, and openend is fixed.Feed fluid in the pipe, under fluid pressure action, bourdon tube deforms, and free end produces displacement of the lines or angular displacement.The measurement category of bourdon tube can be by tens of kPas to more than the lucky handkerchief.Common cross sectional shape has ellipse, flat, circle, and wherein flat tube is applicable to low pressure, and pipe is applicable to high pressure, and dish spirality bourdon tube can be used for the requirement bourdon tube to be had in the instrument of big displacement.For the bourdon tube of set angle, its precision control in welding process is particularly important, and the deviation of its welding can directly cause the accuracy of instrument measurement.Mostly adopt artificial welding C type pipe and its compression fittings at present in the factory, in operating process, the shake of manually operated weld displacement and hand all can further cause the increase of deviation.
Summary of the invention
Technical purpose of the present invention is to overcome defective of the prior art, provides a kind of welding precision high bourdon tube welding fixture.
Technical scheme of the present invention is:
A kind of bourdon tube welding fixture is provided with the welding base, it is characterized in that, said welding base comprises bourdon tube base and pressure interface pipe base, and said welding base is fixed on the work top, and the welding base end face is connected with motor through rotating shaft.During welding, drive motors drives the welding base and rotates according to set angle.
Further technical scheme comprises:
When being used for the welding of C type bourdon tube, said bourdon tube base comprises a fan-shaped fixture block, and said bourdon tube is stuck on the arcwall face of fan-shaped fixture block end face.
One side of fan-shaped fixture block arcwall face is provided with the convex edge of protrusion arcwall face, is used for the retainer spring pipe.
Said fan-shaped fixture block is provided with active blade at the opposite side of arcwall face, and said active blade is fixed on the fan-shaped fixture block through locking device.
Said pressure interface pipe base comprises a horizonal base plate and a riser, and said horizonal base plate is provided with the clamping plate of locking pressure interface pipe, and said bourdon tube base is fixed in the top of said riser.
Said horizonal base plate is fixed in the vertical rotating shaft, said rotating shaft be arranged on the basifacial motor of workbench and be connected.
Both sides in said rotating shaft on the workbench are provided with block.
Bourdon tube welding fixture of the present invention, simple in structure, easy to use.During work bourdon tube and pressure interface pipe be stuck on the welding base and locate; Drive motors drives the rotating shaft rotation then; The welding base is rotated in the angular range that configures, and operating personnel only need stablize and control soldering appliance well, make the welding position slip over solder joint successively; Accomplish welding, effectively avoided the deviation of artificial displacement and the welding error that the hand shake brings.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure, a kind of bourdon tube welding fixture is provided with the welding base, and said welding base comprises bourdon tube base and pressure interface pipe base, and said welding base is fixed on the work top 1, and the welding base end face is connected with motor 41 through rotating shaft 42.
With welding C type pipe is example:
Said bourdon tube base comprises a fan-shaped fixture block 5, during welding C type bourdon tube 3 is stuck on the arcwall face of fan-shaped fixture block 5 end faces, and in like manner, as the bourdon tube that welds other shape then adopts the fixture block that adapts with the bourdon tube shape.
Arcwall face one side of said fan-shaped fixture block 5 is provided with the convex edge 51 of protrusion arcwall face.Said fan-shaped fixture block 5 is provided with active blade 25 at the opposite side of arcwall face; Said active blade 25 is fixed on the fan-shaped side of fan-shaped fixture block 5 through locking device 26; Its up and down the two ends part of stretching out fan-shaped fixture block 5 arcwall faces be against the opposite side of C type bourdon tube 3, to cooperate location C type bourdon tubes 3 with convex edge 51.
Said pressure interface pipe base 22 comprises a horizonal base plate and a riser, and said horizonal base plate is provided with the clamping plate 23 of locking pressure interface pipe, and said bourdon tube base is fixed in the top of said riser.Said horizonal base plate is fixed in the vertical rotating shaft 42, is provided with block 21 in the both sides of said rotating shaft 42 on the work top 1.Said rotating shaft 42 is connected with the motor 41 that is arranged on work top 1 bottom.
During work; The pressure interface pipe is placed on the base; C type bourdon tube 3 is stuck on the fan-shaped fixture block 5 of bourdon tube base, C type bourdon tube 3 one sides are against on the convex edge 51, then the active blade 25 of fan-shaped fixture block 5 opposite sides is locked; With clamping plate 23 lockings, make pressure interface pipe and C type bourdon tube 3 positioning and fixing good.During welding, drive motors control welding base rotates, and needs the position of welding to slip over solder joint successively between C type bourdon tube and the pressure interface pipe.The present invention can improve about 0.5 °-1 ° with the precision control of bourdon tube center angle.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
