Description
Technical Field
The utility model relates to a machine-building technical field specifically is a pressure test device for resistance welding.
Background
At present, traditional welding industry resistance weld pressure measurement device mainly relies on the manpower drive oil pump, and oil pump drive hydraulic cylinder, hydro-cylinder rise until with nut or bolt and work piece separation, after the pressure test was accomplished, unclamp the start button, the oil pump returns the original position. Because the detection bolt and nut models are different, the replacement of the pressure head is inconvenient, data is required to be recorded by the pressure head, the efficiency is very low, and the labor intensity is very high.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide an automatic pressure testing machine which is used for automatically detecting and recording pressure values.
In order to realize the purpose, the upper part of the machine base of the utility model is provided with a replaceable pressure head, an oil cylinder and a control display screen, a pressure transmitter is arranged in the oil cylinder, the control display screen and the pressure transmitter are connected with a control system, and a pneumatic oil pump is arranged on a workbench of the machine base; the guide sleeve of the replaceable pressure head is fixed on the upper part of the machine base, the guide rod penetrates through a guide hole of the guide sleeve, the spring is sleeved between the head pressing plate of the guide rod and the guide sleeve, the lower part of the guide rod is provided with a bending part, and the movable pressure head is arranged on the edge part of the bending part; a pressure head at the bottom of the oil cylinder is provided with a clamping groove; the pneumatic oil pump is connected with a pedal switch of the pneumatic oil pump, and the upper part of the pneumatic oil pump is provided with a groove.
Pulling down a replaceable pressure head matched with a nut or a bolt, sleeving a movable pressure head in a clamping groove of the pressure head at the bottom of an oil cylinder, then placing a workpiece with the nut or the bolt and a plate welded together on a pneumatic oil pump, placing the nut or the bolt in a groove of the pneumatic oil pump, dropping the plate on the upper plane of the pneumatic oil pump, stepping on a pedal switch of the pneumatic oil pump to drive the pneumatic oil pump to ascend until the nut or the bolt props against the replaceable pressure head, and separating the nut or the bolt from the workpiece; the tested pressure is firstly converted into oil pressure through the oil cylinder, the pressure transmitter converts the oil pressure into a voltage signal of 1-5V and transmits the voltage signal to the control system, and the control system converts the voltage signal into a pressure value and displays the pressure value on the control display screen for recording.
Compared with the prior art, the utility model, can convenient and fast ground inspect the welding strength of weld nut, bolt, do not need the manpower drive oil pump, change pressure head convenient and fast can automatic recording pressure value and judge whether qualified, the big screen gathers the pressure test data of each press in real time, can increase substantially production efficiency and degree of automation, greatly reduced operation personnel's intensity of labour and manufacturing cost.
