A kind of welding insulation frock
Technical field
The present invention relates to frock, particularly a kind of welding insulation frock.
Background technology
The axial workpiece of some accurately machined metal material needs at one end, and spindle nose welds other metal parts; and when carrying out the arc welding operation; the easy sputter of welding slag that produces hurts the surface of axial workpiece; affect the quality of whole product; therefore need to carry out certain protection to these accurately machined axial workpieces, can not affect normal weld job and welding precision again simultaneously.
Summary of the invention
Problem to be solved by this invention just is to provide a kind of welding insulation frock, and is simple in structure, easy to use, protects accurately machined Axle Surface, improves simultaneously welding precision.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of welding insulation frock, it is characterized in that: comprise the pedestal of metal material and vertically be located at the sleeve of metal material on pedestal, be provided with in sleeve axle spare is cut off the insulation system that comes from the electric welding loop.
Further, described insulation system comprises the dead ring that is located in sleeve and is located at the insulation sleeve that the sleeve bottom encases axle spare lower end spindle nose, be provided with the through hole that coordinates with axle spare in dead ring, be provided with the groove, the axis of through hole and groove and the dead in line of sleeve that coordinate with axle spare lower end spindle nose in insulation sleeve.Axle spare upper end spindle nose is connected in welding circuit, but axle spare other positions can't form the loop through the insulation location; be that axle spare other positions except the spindle nose of upper end are non-conductive; also just can not produce spark, sleeve can block the welding slag that welding produces, and axle spare is protected.
Further, described groove and axle spare lower end spindle nose interference fit.Can with the tightening of axle spare, be convenient to weld job like this.
Further, the upper end oral area of described through hole is provided with chamfering.Being convenient to axle spare installs in sleeve downwards.
Further, the upper end oral area of described groove also is provided with chamfering.Be convenient to axle spare lower end spindle nose automatic alignment and enter groove.
Further, described sleeve upper end end face is vertical with sleeve axis.Perpendicularity requirement in the time of can satisfying like this welding of some part and axle spare.
Further, laterally be provided with screwed hole on the cylindrical shell of described sleeve, be provided with the screw of cooperation in screwed hole, screw is screwed in dead ring dead ring is positioned in sleeve.
After adopting technique scheme, the present invention has following advantage: axle spare is positioned in the environment of relative closure, it is surperficial that the welding slag that welding produces can't hurt axle spare, guarantees the precision of axle spare, to axle spare and soldering part auxiliary positioning, improved welding precision simultaneously.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of an embodiment of the present invention.
The specific embodiment
The structural representation of an embodiment of the present invention as shown in Figure 1, a kind of welding insulation frock comprises the pedestal 1 of metal material and vertically is located at the sleeve 2 of metal material on pedestal, is provided with axle spare 8 is cut off the insulation system that comes in sleeve from the electric welding loop.
Described insulation system comprises the dead ring 3 that is located in sleeve and is located at the insulation sleeve 4 that the sleeve bottom encases axle spare lower end spindle nose, be provided with the through hole 31 that coordinates with axle spare in dead ring, be provided with the groove 41 that coordinates with axle spare lower end spindle nose in insulation sleeve, the axis of through hole and groove and the dead in line of sleeve; Groove and axle spare lower end spindle nose interference fit.Insulation system also can use other similar structures, such as with insulation sleeve, axle spare being encased fully.
Sleeve upper end end face is vertical with sleeve axis; Laterally be provided with screwed hole 21 on the cylindrical shell of sleeve, be provided with the screw 22 of cooperation in screwed hole, screw is screwed in dead ring dead ring is positioned in sleeve.
In above-described embodiment, the upper end oral area of described through hole is provided with chamfering 32, and the upper end oral area of groove also is provided with chamfering.
The present invention is when electric welding field; bonding is placed on pedestal; welding rod point is at axle spare upper end spindle nose and other weld parts; thereby form the electric welding loop, and except axle spare upper end spindle nose conduction, the part that axle spare is arranged in sleeve does not all enter the electric welding loop; therefore just can not produce disruptive spark yet; and whole axle spare is all surrounded by sleeve, and the welding slag that welding produces can not sputter hurts the surface of axle spare, and the protection effect is very obvious.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
