Description

A kind of body in white is pieced together the automatic checkoff device in advance

Technical field

The utility model belongs to automobile assembling auxiliary mould technical field, specifically relates to a kind of body in white and pieces together the automatic checkoff device in advance.

Background technology

Station is pieced together in total weldering of passenger car body plant in advance, mainly left and right gusset assembly and bottom body assembly is pieced together in advance, simultaneously artificial gusset and bottom vehicle body and cabin assembly and gusset lap flange is withheld.Because total bonding wire bottom vehicle body and left and right sides gusset lap-joint threshold, the space is bigger, and the employee withholds easy and simple to handle, and it is effective to withhold.But the lap flange of cabin and gusset, periphery anchor clamps locating piece and sensor are many especially, and flange locus of living in is narrow and small, cause hammer knock the flange activity space limited, often the situation not in place of withholding appears, exist gusset to sink and the crimp of gusset locating hole when causing the station anchor clamps to close up, influence the body in white quality.

Summary of the invention

The utility model provides a kind of body in white to piece together the automatic checkoff device in advance, and this apparatus structure is simple, makes the process operations of withholding of bottom vehicle body and gusset simple, guarantees to withhold accurately, prevents the distortion of vehicle body locating hole, and is practical.

A kind of body in white is pieced together the automatic checkoff device in advance, comprises base and is located at support portion, compressed part and roll extrusion portion on the base, and described support portion comprises back-up block and drives first cylinder that back-up block moves up and down; Described compressed part comprises compact heap and drives second cylinder that compact heap moves up and down; Described roll extrusion portion comprises the 3rd cylinder that roller and driving rolls move horizontally; Described compact heap be positioned at back-up block directly over.

Take all factors into consideration the own characteristic of assembling workpiece, for ease of assembling, described first cylinder and the 3rd cylinder can be selected the parallel bars cylinder simultaneously, and described second cylinder is the horizontal bar cylinder.Described compact heap can be selected to fix by the clamping arm and the second cylinder piston rod top, and clamping arm bottom surface and base are hinged.

Compact heap bottom end surface shape determines that by the end face shape of the plate that is in contact with it both cooperatively interact, and avoids the generation distortion of plate in the precompressed process; Back-up block top end face determines that by the bottom shape of the plate that is in contact with it both cooperatively interact, and is similarly to avoid the generation distortion of plate in the precompressed process.Be the degree of accuracy that guarantees that compact heap presses down, can between described clamping arm and base top surface position-limit mechanism be set, for example can limited block be set in described clamping arm bottom surface, the limited block bottom surface is provided with stopper slot; Described base top surface is provided with the spacing preiection that matches with the limited block stopper slot, and cooperatively interacting of limited block and spacing preiection guaranteed the degree of accuracy that compact heap presses down, and guaranteed the quality of withholding.

Body in white of the present utility model is pieced together the automatic checkoff device in advance, and is simple in structure, realized the automation of the operation of withholding of bottom vehicle body and gusset, simple to operate, save the activity duration, guarantee to withhold accurately, prevent the distortion of vehicle body locating hole, improved the automobile assembling quality, practical.
