Technical Field

The invention relates to the field of automobile production, in particular to a pre-binding device.

Background

At present, in order to ensure the seam allowance quality, the seam allowance speed of a region with sharp edge folding transition (such as a position of a tail lamp of a rear cover of a two-compartment vehicle) is low, the seam allowance quality is difficult to debug, angle pushing is needed for pre-seam allowance, the speed of an existing angle pushing mechanism is low, the production time is increased, the pre-seam allowance quality is difficult to maintain, if the mechanism has problems in the production process, the debugging time is long, and the beat of normal production is influenced; the white body welding workshop of the automobile production factory provides a small process layout space, and the pressing die assembly and the forming die occupy a larger space.

Disclosure of Invention

The present invention is directed to a pre-binding apparatus that overcomes the above-mentioned deficiencies of the prior art.

The purpose of the invention can be realized by the following technical scheme:

a pre-binding device comprises a turntable mechanism provided with a plurality of pre-binding stations, each pre-binding station is provided with a set of positioning mechanism and a set of angle pushing mechanism,

the positioning mechanism comprises a clamping fixture fixed on the pre-binding station and a pressing module arranged above the clamping fixture and used for pressing the workpiece on the clamping fixture,

the angle pushing mechanism comprises a support fixed on the pre-binding station, an angle pushing assembly arranged on the support and a driving assembly for driving the angle pushing assembly to perform pre-binding operation.

Furthermore, the moulding bed anchor clamps include the base to and set up the moulding bed on the base, be provided with sensor and fixed work piece's sucking disc on the moulding bed, moulding bed anchor clamps top still is equipped with the frame of connecting the moulding-die subassembly.

Furthermore, the die assembly comprises a fixedly installed frame, a fixing piece and a pressing block, wherein the fixing piece is connected with the frame in a rotating mode through a rotating shaft, the pressing block is arranged at one end of the fixing piece and used for pressing a workpiece, and the rotating shaft is further connected with a linear cylinder and driven to rotate by the linear cylinder.

Furthermore, the driving assembly comprises an air cylinder, and the output end of the air cylinder is connected with the angle pushing assembly through a four-bar unit and drives the angle pushing assembly to move to perform pre-rolling operation.

Furthermore, the angle pushing assembly comprises a sliding rail fixed on the support, an angle pushing sliding block connected with the sliding rail in a sliding mode, and an angle pushing type block fixedly connected with the angle pushing sliding block.

Furthermore, the sliding rail and the angle push sliding block are both made of copper blocks.

Furthermore, the sliding rail is also provided with an angle pushing sensor for sensing the working position of the angle pushing block.

Further, the support top is equipped with the locating part, the locating part includes limit guide to and gliding spacing slider on limit guide, limit guide both ends are equipped with the fixed block, spacing slider with angle pushes away slider fixed connection. During operation, the limiting slide block moves along with the angle pushing slide block and the angle pushing type block, the stroke of the limiting slide block can be effectively limited through the two fixing blocks, and then the stroke of the angle pushing type block is limited, so that the phenomenon that the pre-rolling edge of the angle pushing type block is excessive is avoided.

Furthermore, the rotary table mechanism comprises a rotary table frame and a rotary table motor for driving the rotary table frame to rotate, and the rotary table frame is provided with 4 pre-binding stations.

When the clamping device works, firstly, a workpiece on the gripper is conveyed to the moulding bed, the sucker is used for adsorption and fixation, a sensor on the moulding bed clamp senses the workpiece and transmits a signal to the moulding-die assembly, and the linear air cylinder drives the rotating shaft to rotate so as to drive the pressing block to rotate and press the workpiece (a vehicle body part); then, the cylinder drives the four-bar unit to drive the angle push type block and the angle push sliding block to move, so that the angle push type block props against a workpiece and performs pre-rolling, and when the angle push sensor senses that the angle push type block reaches a working position, the cylinder stops working; and finally, returning the angle push type block, rotating and opening the pressing block, conveying the gripper to send the pre-rolled assembly piece into a press mold, or only returning the angle push type block, and performing a rolling process by using a rolling robot. The combination of the turntable mechanism and the positioning mechanism can realize the switching among different vehicle types, and the beat is improved.

Compared with the prior art, the invention has the following beneficial effects:

firstly, the production efficiency is improved: the time of pre-rolling is effectively reduced, the production efficiency is improved, and the production quality is ensured.

Secondly, the angle can be pre-folded by unequal angles: the method realizes pre-edge rolling at different angles, can realize pre-edge folding at an angle of 5-15 degrees, and can be used for the position where the edge folding of the tail gate changes sharply.

Thirdly, the cost is reduced: compared with a gripper type die assembly, the rotary die assembly reduces the use of field equipment, such as a robot, a gun changing disc and the like;

fourthly, space utilization rate is improved: the clamping fixture, the die assembly and the angle pushing mechanism are integrated on the same clamping fixture, so that the space for parking the die assembly is reduced, and the space occupied by the clamping fixture is reduced by the turntable mechanism.

Fifthly, the overhaul is convenient: the invention has small structure, and the connecting mechanism is simple and convenient to maintain and replace, so that the connecting mechanism is very convenient to maintain.

Sixthly, the debugging period is short: although the multifunctional clamp integrates multiple functions, the clamp has a simple structure, is convenient for on-site early-stage debugging, and reduces the debugging time.
