Embodiment Construction

[0021] like figure 2 , image 3 The door frame column 1 shown is assembled and welded by stamping parts 1A, 1B and rolling part 1C. Stamping parts 1A, 1B and rolling part 1C are made of thin metal strips. After assembly and welding, stamping parts 1A and 1B A hollow part 1D with a large space is formed between them, and thick-walled regions 1E and 1F are formed on both sides thereof, one end of which is the end 1G to be cut; implementation.

[0022] A door frame column clamping device used for sawing automobile door frame column 1, such as Figure 4 to Figure 10 As shown, it includes a base 2 suitable for fixed installation to the door frame column sawing machine. Specifically, two mounting holes can be provided under the base 2, so that it can be fixed and installed to the general saw wheel sawing machine with bolts. On the frame of the machine; one side of the base 2 is provided with a hydraulic cylinder 3, the hydraulic cylinder 3 can also be replaced by a cylinder, the...

Abstract

The invention provides a door frame strip column clamping device which is suitable for being used when a door frame strip column with a complex cross section shape is sawed and can be mounted on a door frame strip column sawing machine commonly used at present. The door frame strip column clamping device comprises a base 2, a hydraulic cylinder 3, a movable block 4, a fixing and mounting plate 5, a workpiece positioning block 6 and a swing clamping block 7, wherein the swing clamping block 7 is provided with a downwardly bent and extended extension section 8 and can rotate around a rotating shaft 10 to clamp or unclamp the door frame strip column; a horizontal driving plate 11 is arranged on the fixing and mounting plate 5 and can rotate around a driving plate rotating shaft 12 in the middle of the driving plate 11; a transfer block 13 is arranged on the movable block 4 and is against the left end of the driving plate 11; a first pull spring 14 is arranged at the left end of the driving plate 11; the right end of the driving plate 11 is against the lower end of the extension section 8 of the swing clamping block 7; and a second pull spring 15 is arranged at the lower end of the extension section 8.

Description

technical field [0001] The invention relates to a clamping device for a door frame column used for sawing an automobile door frame column, in particular to a clamping device suitable for a door frame column with complex cross-sectional shapes. Background technique [0002] At present, most automobile door frames are made of metal strips through rolling or stamping to form door frame strips or door frame posts, which are collectively referred to as door frame posts, and then the door frame posts are processed into door frames by welding or other connection methods. A certain margin should be left during rolling or stamping processing. Since the door frame columns need to be welded between the columns, and the requirements for welding surface bonding are very high, the welding surface of the door frame columns before processing into the door frame needs to be precise. sawing processing. In order to save equipment investment, the sawing machines of the door frame manufacturers...
