Technical field
The utility model is related to a kind of devices for welding procedure, and in particular to a kind of resistance welding hold-down mechanism.
Background technology
Resistance welding is the method being attached using electric current by the resistance heat that the contact surface of metal weldment generates.Due to
It is short that resistance welding possesses heating time, and heat is concentrated, and deforms small with stress after welding, usually need not arrange correction and hot in postwelding
Treatment process；Welding wire is not required in welding simultaneously, and welding cost is low；It is and easy to operate, it is easy to accomplish mechanization and automation, it is raw
The features such as efficient is produced, so resistance welding is widely used in the manufacturing fields such as aerospace, electronics, automobile, household electrical appliance.
Automobile fuel pump support product also begins to largely use resistance welding technology at present, is mainly used for the weldering of pump core and harness
It connects, following steps is broadly divided into entire welding procedure engineering：1：Harness is plugged into pump core by personnel；2：Startup is set
Standby harness is pressed with pump core；3 equipment are welded.
In the welding process, equipment needs to weld after being pressed harness and pump core as requested, and when press fitting is present with
Harness head can not be completely forced into oil pump inserted sheet, since harness press fitting is using one section of press fitting, as shown in Figure 1, in actual life
Due to the reasons such as press mounting structure systematic error, part cooperation fluctuation during production, it can cause harness 2 can not 100% press-in pump core
The defects of inserted sheet 1, therefore product defects is caused after the completion of welding, cause product rejection.So for such defect, it is badly in need of to existing
There is mechanism to be reformed, solve the problems, such as existing production.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of resistance welding hold-down mechanisms, can ensure harness
Head and rear portion can uniform stressed be pressed, harness head is completely forced into inserted sheet, eliminates weld defect.
In order to solve the above technical problems, resistance welding hold-down mechanism provided by the utility model, including：Compressing unit,
The compressing unit includes pressure head one and pressure head two；The pressure head one and pressure head two are located at welding inserted sheet both sides, the pressure respectively
The first downward harness head for compressing welding inserted sheet one side, the pressure head two compress downwards the harness of welding inserted sheet opposite side；It drives
Moving cell, the driving unit connect compressing unit, and the driving unit is used to that compressing unit to be driven to be pressed downward stringing beam；Control
Unit, described control unit are connected with driving unit, for controlling the movement of driving unit.
The advantageous effect of the resistance welding hold-down mechanism of the utility model is：Harness pressure head ensure that during press fitting
Harness head and rear portion can uniform stressed be pressed；So that product quality uniformity is effectively controlled, reduce simultaneously
Internal losses rate, realizes the versatility of standby redundancy between each production line, and reduces standby redundancy expense.
Preferably, pressure head one and pressure head two are fixedly connected on same pedestal.
Preferably, the driving unit includes cylinder.
Preferably, harness is pressed to welding inserted slot bottom position by the pressure head one and pressure head two.
Preferably, described control unit control driving unit is moved in three dimensions, for positioning the position of pressure head.
Preferably, the pedestal is connected to be replaceable on compressing unit.

Specific embodiment
As shown in Figure 2 and Figure 3, resistance welding hold-down mechanism includes compressing unit, driving unit and control unit, the pressure
Tight unit includes pressure head 1 and pressure head 25；The pressure head 1 and pressure head 25 are located at 1 both sides of welding inserted sheet, the pressure head respectively
One 4 compress downwards the harness head 8 of 1 one side of welding inserted sheet, and the pressure head 25 compresses downwards the harness of welding 1 opposite side of inserted sheet
2；Driving unit connects compressing unit, and the driving unit is used to that compressing unit to be driven to be pressed downward stringing beam 2；Control unit is with driving
Moving cell is connected, for controlling the movement of driving unit.Pressure head 1 and pressure head 25 are fixedly connected on same pedestal 7, and
The amplitude of pushing is consistent, ensures 2 uniform force of harness.The driving unit includes cylinder 6, can also be electric pushrod or hydraulic pressure
Push rod or other electric structures.Harness 2 is pressed to 1 trench bottom position of welding inserted sheet by the pressure head 1 and pressure head 25, is ensured
Per a batch Product jointing uniform quality.Described control unit control driving unit is moved in three dimensions, is pressed for positioning
First 4 and the position of pressure head 25, in the horizontal plane, control unit control pressure head 1 and the alignment of pressure head 25 need the position pushed
It postpones, pressure head 1 and pressure head 25 push harness 2.It is welded after harness 2 is pressed with pump core 3.The pedestal 7 is replaceable
