Abstract
A plant nail welding handle intensity detection tool, is related to field of machining.Bolt collar is linked together by shaft and handle, and ejector pin is placed in handle, and ejector pin end is withstood on the inclined-plane of bolt collar, and in handle, plug screw is screwed into handle spring, and spring is made to generate prepressing deformation.The utility model bolt collar is sleeved on the bolt being welded, driving handle, and spring compression force acts on ejector pin and promotes bolt collar, bolt, which starts stress, warp tendency, and after handle rotates more than vertical angle, spring starts to reset, the power acted on bolt disappears, and detection process is completed.It can be by adjusting spring pressure, meet the detection of different model bolt, and pass through bolt collar top bevel structure, make to act on the bending force on bolt and reach meeting quick disappearance after critical value, bolt will not be bent over, and to realize bolt non-damaged data, can effectively mitigate operating personnel's labor intensity, it eliminates previous tap and detects caused erroneous judgement risk, detection efficiency can be increased substantially.
Description
Technical field
The utility model is related to machinery manufacturing technology fields, are specifically that one kind is used to plant nail welding intensity non-damaged data
Instrument.
Background technology
There are two ways to automobile metal plate work weld bolt.One kind is projection welding bolt, and another kind is arc discharge welding, is commonly called as planting
Nail.Plant tack welding need not the perforate on sheet metal component, clamp weld bolt using arcing welding gun, electrode and sheet metal component are enclosed in outside with one
Contact, certain pressure is imposed by electric arc, and bolt and sheet metal component is made to contact surface and melt completion welding.Tack welding is planted to be mainly used for welding
Connect that intensity requirement is not high, such as the occasion that harness, buckle installation stress are small.At present, nail welding intensity on-line checking is planted, mainly
Mode is tapped with wooden mallet by operating personnel, inspecting force control is bad, be easy to cause erroneous judgement.
The content of the invention
For overcome the deficiencies in the prior art, the goal of the invention of the utility model is to provide a plant nail welding intensity detection
Instrument, to realize online quick judgement bolt welding quality.
For achieving the above object, the bolt collar of the utility model is linked together by shaft and handle, ejector pin
It is placed in handle, the end of ejector pin is withstood on the inclined-plane of bolt collar, and in handle, plug screw is screwed into handle spring, makes bullet
Spring generates prepressing deformation.
The center band of the bolt collar lower part is useful for the hole of set bolt；The top of bolt collar is by two symmetrical slope groups
Into；The top band of bolt collar is useful for the hole of assembling shaft, and the center in hole and two inclined-planes are symmetrical；The top of bolt collar carries
The groove rotated convenient for handle end.
The end that the ejector pin is contacted with bolt collar is arc structure.
The bolt collar of the utility model is sleeved on the bolt being welded, and driving handle, spring compression force acts on ejector pin
It goes up and promotes bolt collar, bolt, which starts stress, warp tendency, and after handle rotates more than vertical angle, spring starts multiple
Position, the power acted on bolt disappear, and detection process is completed.
The utility model compared with prior art, can meet the detection of different model bolt by adjusting spring pressure,
And designed by the ramp structure at the top of bolt collar, making to act on after the bending force on bolt reaches critical value quickly to disappear
It loses, bolt will not be bent over, to realize the non-damaged data of bolt.It is simple in structure compact, it is easy to use, it can effectively mitigate work
The labor intensity of industry personnel eliminates the previous risk for tapping the caused erroneous judgement of detection, can increase substantially inspection to a certain extent
Efficiency is surveyed, there is preferable popularization reference function.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model is mainly by bolt collar 3, shaft 4, handle 5, ejector pin 6, bullet
Spring 7, plug screw 8 form.Bolt collar 3 is linked together by shaft 4 and handle 5, and ejector pin 6 is placed in handle, the end of ejector pin 6
Portion is withstood on the inclined-plane of bolt collar 3, and in handle 5, plug screw 8 is screwed into handle 5 spring 7, and spring 7 is made to generate pre- buckling
Shape, the end of handle 5 are packed into plug screw 8, the pressure of adjustable springs 7.
The center of 3 lower part of bolt collar carries hole, for covering bolt 2；The top of bolt collar 3 is by two symmetrical slopes
Composition；The top of bolt collar 3 carries hole, and for assembling shaft 4, the center in hole and two inclined-planes are symmetrical；The top of bolt collar 3
With fluted, rotated convenient for 5 end of handle.
The end that the ejector pin 6 is contacted with bolt collar 3 is arc structure.
During detection, bolt collar 3 is inserted on the bolt 2 being welded with plate 1, driving handle 5 turns left, and rotates
Cheng Zhong, 6 stress of ejector pin withstand on 3 right side inclined-plane of bolt collar and start to press against in handle 5, and spring 7 is forced to compress；Spring 7
Pressure passes to bolt collar 3 by ejector pin 6, is then passed to bolt 2, and bolt 2 is caused to have flexural deformation trend；If spiral shell
Larger deformation occurs for bolt 2, and process terminates, and illustrates the weld strength deficiency of bolt 2.If bolt 2 is moved to without deformation, ejector pin 6
Behind the top of bolt collar 3, start to glide along its left side inclined-plane and stretch out, the active force of spring 7 reduces, and acts on bolt 2
Power disappears, and can play the effect that bolt 2 is protected not to be destroyed, the weld strength of bolt 2 is determined as qualification.
