It closes in the positioning groove of locating piece.
3) the auxiliary centering support fixture includes support plate, and the upper end of the support plate is provided with fixed plate, fixed plate
Middle part be provided with spaced apart two positioning columns, the positioning groove with work pieces mate is formed between two positioning columns.
Further, horizontally disposed gain is provided in the middle part of fixed plate, the lower end of two positioning columns is provided with downwards
Across the screw rod of gain, across fixed plate screw rod on be threaded with locking nut, allow two positioning columns along waist
Slot adjusting position.
The auxiliary centering support fixture of the structure realizes the support and positioning to pipe fitting by two positioning columns, while two fixed
Position column can be along gain adjusting position, it is ensured that realizes the positioning to pipe fitting along two side directions.
4) the auxiliary centering support fixture includes support plate, and the upper center of support plate is provided with accommodation groove, accommodation groove
It is inside equipped with locating piece, the location hole of locating piece being provided centrally with for placing workpiece and matching with workpiece is described
The two sides of accommodation groove are provided with the clamping plate for sandwiched locating piece, and the open slot for placing workpiece is provided on clamping plate.
The auxiliary centering support fixture of the structure is provided with locating piece, and locating piece is provided with the location hole with work pieces mate,
Locating piece is installed in the accommodation groove of support plate upper center by clamping plate, therefore can be replaced according to pipe fitting cross sectional shape different
Locating piece, to adapt to various different pipe fittings.
