Description

A kind of bolt welding intensity detecting device

Technical field

The utility model relates to a kind of pick-up unit, is particularly useful for the detection to the weld bolt weld strength, belongs to technical field of measurement and test.

Background technology

In equipment manufacture; The application of weld bolt very extensively; For example automobile factory all need realize the assembling of annex through weld bolt on parts such as side bar and water tank suspension bracket under car door column, the vehicle body, so the weld strength of weld bolt directly affects the car load assembly quality.But at present the time, generally adopt to strike with iron hammer and pound and the range estimation mode,, have the examination criteria disunity, the disadvantage that the testing result accuracy is relatively poor because of testing conditions is lacked the constraint that datumizes by manual work to bolt welding ruggedness test; Simultaneously workpiece is struck to pound and cause surface deformation easily, influence car load assembly quality and vehicle performance, and operator's labour intensity is big, inefficiency.

The utility model content

The purpose of the utility model is the drawback to prior art, provide a kind of simple in structure, practical, can effectively improve detection efficiency and reduce the bolt welding intensity detecting device of operator's labour intensity.

The said problem of the utility model realizes with following technical proposals:

A kind of bolt welding intensity detecting device, it comprises cylinder, cylinder support, pullover, fixed head and worktable, said cylinder is installed on the cylinder support; Said cylinder support is fixed on the worktable; Said pulloverly be made up of upper bush and lower sleeve, said upper bush is installed in the ejecting rod of cylinder lower end, said lower sleeve and upper bush central axes; Lower sleeve is fixedly mounted on the fixed head, and said fixed head is installed on the lateral edges position of table surface.

Above-mentioned bolt welding intensity detecting device also comprises electromagnetic switch in the formation, said electromagnetic switch is provided with up button and descending button, and electromagnetic switch is connected in the control circuit, is fixed on the cylinder support.

Above-mentioned bolt welding intensity detecting device also comprises pneumatic triple piece in the formation, said pneumatic triple piece is made up of oil-water separator, reduction valve and oil sprayer, and they all are connected in the control gas circuit, are fixed on the worktable corresponding position.

The utility model improves present weld bolt weld strength manual detection mode; Utilize pneumatic triple piece to regulate gas cylinder working condition; Through control ejecting rod of cylinder is complementary to the top value of thrust of stipulating in tested bolt applied pressure and the weld strength examination criteria,, has characteristics simple in structure, workable, the examination criteria datumization by ejecting rod of cylinder and the detection that cooperates completion bolt weld strength of sleeve up and down to the cylinder atmospheric pressure value; After adopting the utility model; Not only can make testing result more accurately and reliably, but also reduce operator's labour intensity, improve detection efficiency.
