Description

Technical Field

[0001] This invention relates to the field of commercial vehicle frame assembly technology, and in particular to an automatic longitudinal beam flipping device and a longitudinal beam transfer station. Background Technology

[0002] The longitudinal beam is the most important component of the commercial vehicle frame. It is long and heavy. In general medium and heavy trucks, the longitudinal beam assembly is usually 6-12 meters long and weighs up to 1 ton.

[0003] Many connecting plates, leaf spring brackets and other accessories need to be arranged on the inner and outer sides of the longitudinal beam. During the frame assembly process, the longitudinal beam is usually placed on a fixed assembly table in advance. The accessories on one side are assembled manually first. After the assembly is completed, the longitudinal beam is rotated 180 degrees with a pry bar and the parts on the other side are assembled. When the assembly table interferes with the installation position, the longitudinal beam needs to be dragged and moved aside manually. Finally, the longitudinal beam is lifted to the next work station using a hoist.

[0004] The entire assembly process is labor-intensive, and the longitudinal beams are easily scratched when flipped, posing safety hazards and noise. Therefore, there is an urgent need for a device that can be applied on the chassis assembly line, which can adjust the support position according to different vehicle models, meet the needs of adjusting the longitudinal beams at different rotation angles during the parts installation process, and can be quickly transferred to the next assembly station. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an automatic longitudinal beam flipping device and a longitudinal beam transfer station, which prevents longitudinal beams from being scratched during the transfer process, reduces safety hazards and noise pollution during assembly flipping, can adjust the support points of the longitudinal beam products according to the needs of different vehicle models, and meets the requirements of different rotation angles of the longitudinal beams, and can be quickly transferred between the loading station and the assembly station.

[0006] This invention proposes an automatic longitudinal beam tilting device, including a base, a traveling device, a longitudinal beam tilting device, and a longitudinal beam limiting and clamping device.

[0007] The traveling device is located on the lower end face of the base. The two traveling devices can drive the matching base to move back and forth on the track, and drive the longitudinal beam fixed on the base to move quickly back and forth on the track from the loading station to the assembly station. The two traveling devices can be moved to the underside of the longitudinal beam hoisted by the lifting device according to the set support point parameters based on the length of the longitudinal beam of different vehicle models. A pair of longitudinal beams with assembly are transferred and assembled for support.

[0008] The longitudinal beam flipping device is set on the upper end face of the base. The longitudinal beam flipping device can flip at any angle within 0°-180° along the horizontal axis. The longitudinal beam flipping device can drive the longitudinal beam fixed on it to flip at a specified angle according to the assembly sequence, so as to install accessories such as connecting plates and leaf spring brackets on different side end faces of the longitudinal beam.

[0009] The longitudinal beam limiting clamping device is set on the longitudinal beam flipping device, and the longitudinal beam limiting clamping device flips synchronously with the longitudinal beam flipping device. It can limit and clamp the longitudinal beam in both Y and Z directions (X direction is the longitudinal beam length direction, Y direction is the longitudinal beam width direction, and Z direction is the longitudinal beam height direction), so that the longitudinal beam can be flipped synchronously by the two longitudinal beam flipping devices, and the assembly of accessories such as connecting plates and leaf spring brackets on different side end faces of the longitudinal beam can be realized. This eliminates the problems of longitudinal beam collision and scratches and noise caused by using a pry bar to flip the longitudinal beam in the existing technology.

[0010] The longitudinal beam tilting device includes a support base, a tilting motor, a C-shaped arc guide groove, and a C-shaped arc tilting arm. The support base is fixed to the upper surface of the base. The C-shaped arc guide groove is fixed to the upper surface of the support base with its opening facing upwards, and the axis of the C-shaped arc guide groove is aligned with the X-direction. The C-shaped arc tilting arm is matched and slidably connected within the C-shaped arc guide groove, with its front end exposed outside the front end of the C-shaped arc guide groove. The C-shaped arc tilting arm can reciprocate at any angle within the range of 0°-180° along the C-shaped arc guide groove. The tilting motor is located in front of the C-shaped arc guide groove. The arm is placed horizontally on one side of the support base, and the output shaft of the flipping motor meshes with the outer end of the C-shaped arc flipping arm. The flipping motor can drive the C-shaped arc flipping arm to flip back and forth along the C-shaped arc guide groove from opening upward to opening downward. The longitudinal beam limiting clamping device is set on the rear end face of the C-shaped arc flipping arm. The longitudinal beam telescopic clamping arm of the longitudinal beam limiting clamping device cooperates with the C-shaped opening of the C-shaped arc flipping arm to limit and clamp the longitudinal beam in both Y and Z directions, so that the front and rear longitudinal beam flipping devices can rotate synchronously and drive the longitudinal beam as a whole to be assembled according to the required flipping angle.

[0011] The C-shaped arc guide groove includes two identical C-shaped inner arc support plates and several sliding support cams. The lower ends of the two C-shaped inner arc support plates are symmetrically fixed to the front and rear end faces of the protrusion on the upper end face of the support base by bolts. A gap is provided between the two C-shaped inner arc support plates. Several sliding support cams are evenly distributed on the circumferential sheet outside the inner arc surface of the C-shaped inner arc support plate. The C-shaped arc flipping arm includes a C-shaped arc open ring, a C-shaped arc rack, and a longitudinal beam limiting support block. The outer circumferential surface of the C-shaped arc open ring is matched and slidably accommodated in the gap between the two C-shaped inner arc support plates, and the outer circumferential surface of the C-shaped arc open ring rolls in contact with several sliding support cams respectively. The inner circumferential surface of the C-shaped arc open ring protrudes outside the inner arc surface of the C-shaped inner arc support plate, so that the front and rear end faces of the C-shaped arc open ring respectively contact the C-shaped arc rack and the longitudinal beam limiting support block. The beam limiting clamping device is fixedly connected. The rear end face of the C-shaped arc rack is bolted to the front end face of the aligned C-shaped arc open ring. The outer circumference of the C-shaped arc rack is provided with teeth arranged in an arc structure. The C-shaped arc rack meshes with the output shaft of the flip motor for transmission. Through the transmission of the flip motor meshing with the C-shaped arc rack, the C-shaped arc open ring can move from the initial position of 0° upward opening to the position of several sliding support cams arranged along the arc shape. The opening is rotated 180° downwards in an inverted position; the longitudinal beam limiting support block is a circular plate, which is matched and embedded in the inner circumference of the C-shaped arc opening ring. The upper part of the circular plate has a longitudinal beam receiving groove, and the side end face and bottom face of the longitudinal beam can be limited to contact the longitudinal beam receiving groove. The telescopic clamping arm of the longitudinal beam limiting clamping device retracts and cooperates with the longitudinal beam receiving groove to limit and clamp the aligned longitudinal beam Y-direction side wall, so as to drive the longitudinal beam to rotate along the X-axis from 0° to 180°.

[0012] The inner circumference of the two C-shaped inner arc support plates is symmetrically bent inward and has a limiting arc edge. The cross-section of the C-shaped arc opening ring is T-shaped. The outer circumference of the horizontal arm of the T-shaped structure has a limiting guide groove corresponding to the position of the sliding support cam. The bottom wall and the two side walls of the limiting guide groove can make limiting rolling contact with the corresponding position of each sliding support cam. The inner circumference of the horizontal arm of the T-shaped structure opposite to the limiting guide groove slides and slides with the limiting arc edges of the two C-shaped inner arc support plates. The limiting of the two C-shaped inner arc support plates... The arc edge provides anti-detachment limiting for the C-shaped arc-shaped open ring during rotation from 0° to 180°, preventing the C-shaped arc-shaped open ring from detaching from the inner circumference of the two C-shaped inner arc support plates during rotation. The design of the limiting guide groove and the sliding support cam ensures that the C-shaped arc-shaped open ring will not move back and forth in the X direction when sliding along the 3 / 4 arc guide structure formed by several sliding support cams. This prevents the axis of the rotating C-shaped arc-shaped open ring from not being aligned with the axis of the two C-shaped inner arc support plates, which could cause the C-shaped arc-shaped open ring to flip and get stuck.

[0013] The inner circumferential surfaces of the two C-shaped inner arc support plates, the inner and outer circumferential surfaces of the C-shaped arc open ring, and the inner and outer circumferential surfaces of the C-shaped arc rack are all 3 / 4 circular surfaces. This 3 / 4 circular surface structure design ensures that when the output shaft of the flip motor meshes with the C-shaped arc rack, the two ends of the C-shaped arc open ring, which flips from the initial 0° opening-up position to the 180° opening-down position, can be accurately slidably accommodated in the groove space on both sides of the upper part of the C-shaped arc guide groove, so that the longitudinal beam that is limited and fixed can rotate 180 degrees around the X-axis.

[0014] The longitudinal beam limiting clamping device includes a telescopic cylinder, a Y-axis translational guide groove, a longitudinal beam telescopic clamping arm, and a longitudinal beam fixed clamping arm. The Y-axis translational guide groove is horizontally fixed to the middle of the rear end face of the longitudinal beam limiting support block. The telescopic cylinder is horizontally fixed to the lower part of the rear end face of the longitudinal beam limiting support block. The longitudinal beam fixed clamping arm is fixed to one side wall of the longitudinal beam receiving groove of the longitudinal beam limiting support block. The longitudinal beam fixed clamping arm has an inverted L-shaped structure. The inner side wall of the short arm of the inverted L-shaped structure of the longitudinal beam fixed clamping arm is provided with a guide slope to facilitate… The longitudinal beam slides down the guide slope into the longitudinal beam receiving groove. The short arm end of the inverted L-shaped longitudinal beam fixing clamping arm can limit the longitudinal beam fixed in the Y direction in the Z direction, preventing the longitudinal beam, which is rotated 180° with the longitudinal beam flipping device, from falling downward from the opening end of the longitudinal beam flipping device due to gravity. The telescopic arm of the telescopic cylinder is set towards the opposite side of the longitudinal beam fixing clamping arm. The entire longitudinal beam telescopic clamping arm is made of F-shaped sheet material. The middle horizontal arm of the longitudinal beam telescopic clamping arm slides on the Y-direction translational guide groove. The lower end of the vertical arm is fixed to the free end of the telescopic arm of the telescopic cylinder. The telescopic cylinder can drive the longitudinal beam telescopic clamping arm to move along the Y-axis towards the side of the longitudinal beam fixed clamping arm. The upper and middle horizontal arms of the F-shaped structure of the longitudinal beam telescopic clamping arm can flip and limit the upper and lower end faces of one side of the longitudinal beam. This, combined with the short arm of the inverted L-shaped structure of the longitudinal beam fixed clamping arm, prevents the longitudinal beam from falling off after a 180° flip. After the vertical arm between the upper and middle horizontal arms of the F-shaped structure of the longitudinal beam telescopic clamping arm moves inward, it can engage with the inverted... The L-shaped longitudinal beam fixing clamping arm and vertical arm work together to limit and fix the side walls at both ends of the longitudinal beam in the Y direction. The telescopic cylinder, Y-direction translation guide slide, longitudinal beam telescopic clamping arm and longitudinal beam fixing clamping arm work together to limit and fix the longitudinal beam in the longitudinal beam receiving groove of the longitudinal beam limiting support block. This allows the longitudinal beam to reciprocate between 0° and 180° with the C-shaped arc flipping arm. According to the assembly sequence requirements, the flipping angle of the longitudinal beam can be adjusted along the X-axis to facilitate the assembly of accessories such as connecting plates and leaf spring brackets on the longitudinal beam.

[0015] The base includes a base body and a counterweight. The counterweight is fixed to the upper surface of the base body to provide sufficient weight and prevent the base from tipping over due to its high center of gravity during the rotation of the longitudinal beam. The traveling device includes a forward and reverse motor, two pairs of track wheels, and four track protection devices. The forward and reverse motor is fixed to the middle of the lower surface of the base body. The two pairs of track wheels are rotatably connected to the front and rear of the lower surface of the base body, respectively. The output end of the forward and reverse motor is connected to the rotating shaft in the middle of a pair of track wheels via a worm gear drive. The forward and reverse motor drives the pair of track wheels to move the base forward and backward. The four track protection devices are respectively fixed to the outer circumference of each track wheel. On the outer wall of the body, each track protection device includes a U-shaped protective wheel cover and a clearing pin. The U-shaped protective wheel cover is aligned and fixed to the outer wall of the base body on the circumferential side of the track wheel. The lower end of the wheel cover wall of the U-shaped protective wheel cover is adjacent to the upper part of the track surface. The purpose of the U-shaped protective wheel cover is to prevent foreign objects on the track surface from being rolled into the track wheel and to prevent the track wheel from falling off the track. The clearing pin is vertically fixed to the left or right side of the lower end face of the wheel cover wall at one end of the running direction of the U-shaped protective wheel cover. The function of the clearing pin is to remove any missing bolts that may be in contact with the inner or outer wall of the track during operation, and to prevent the bolts from jamming the travel of the track wheel.

[0016] A longitudinal beam turning station includes two automatic longitudinal beam turning devices and a track. The track includes an elongated rectangular groove, with two steel rails symmetrically arranged on the left and right sides of the bottom of the groove. The track wheels of the two automatic longitudinal beam turning devices are respectively aligned and rolled on the two steel rails of the track. The bottom walls of the grooves at the inner ends of the two steel rails are symmetrically provided with cable drag chain receiving slots. Two cable drag chains are respectively housed in their corresponding cable drag chain receiving slots. The cables at the inner ends of the two cable drag chains are electrically connected to the turning motor, telescopic cylinder, and forward / reverse motor of the aligned automatic longitudinal beam turning device. The cable drag chains are designed to prevent the cables supplying power and transmitting commands to the two automatic longitudinal beam turning devices from tangling together during reciprocating movement, thus interfering with the operation of the automatic longitudinal beam turning devices on the steel rails. The cable drag chain receiving slots allow the cable drag chains to move vertically in a serpentine pattern within the slots, avoiding irregular tangling of the cables. A plate chain is installed on the upper end cover of the cable drag chain receiving groove. The plate chain covers the opening end of the cable drag chain receiving groove to prevent debris or bolts from falling into the receiving groove and affecting the travel trajectory of the cable drag chain. The traveling device also includes a plate chain cable travel guide device. This plate chain cable travel guide device is set on the lower end face of the base at the left / right end of the forward / reverse motor. The inner end of the cable drag chain is fixed to the lower end face of the plate chain cable travel guide device. The cable drag chain can move back and forth along the rail with the automatic flipping device of the longitudinal beam and move in a serpentine motion within the cable drag chain receiving groove. The plate chain is slidably connected to the plate chain cable travel guide device. The plate chain forms a triangular avoidance space above the inner end of the cable drag chain corresponding to the position of the inner end of the cable drag chain. This allows the plate chain to rise at the corresponding position on the track when the cable moves to a certain point, creating an avoidance space and preventing the plate chain from still covering the opening of the cable drag chain receiving groove at that position and affecting the travel of the cable.

[0017] The cable drag chain avoidance guide device includes two spring rollers, a support frame, and three sets of cable drag chain avoidance guide bearings. The upper end of the support frame is fixed to the lower end face of the base on the left / right side of the forward / reverse motor. The inner end of the cable drag chain is fixed to the lower end face of the support frame. The three sets of cable drag chain avoidance guide bearings are arranged horizontally in the Y direction in an isosceles triangle structure and are rotatably connected to the inner wall of the support frame. The lower end face of the cable drag chain is slidably connected to the outer end of the three sets of cable drag chain avoidance guide bearings, so that the cable drag chain is raised inside the support frame to form a triangular avoidance space. To avoid the displacement of the cable within the cable drag chain receiving groove, a spring pressure roller is fixedly connected to the lower end face of the base at both ends of the support frame. The roller of the spring pressure roller can be pressed against the upper end face of the aligned plate chain through the spring elasticity, so as to ensure that the plate chain only lifts near the support frame to create clearance space. This avoids the plate chain from lifting too much and causing lateral displacement, and also avoids the plate chain from lifting too much and causing foreign objects to fall from the side end of the automatic tilting device of the longitudinal beam into the cable drag chain receiving groove below the lifted plate chain, thereby affecting the displacement stroke of the cable drag chain.

[0018] A longitudinal beam transfer station further includes two sets of longitudinal beam assembly and detection devices. Each set of longitudinal beam assembly and detection devices includes an angle sensor, a proximity switch, and a distance sensor. The angle sensor is set on the side wall of the rear end face of the C-shaped arc guide groove of each longitudinal beam automatic tilting device to detect the tilting angle during the tilting process. If the tilting angle of the two longitudinal beam automatic tilting devices differs during operation, the assembly work can be stopped to prevent the longitudinal beam automatic tilting device from tipping over due to asynchrony. The proximity switch is set on the inner side wall of the tilting motor of each longitudinal beam automatic tilting device to ensure that the longitudinal beam's position in the length direction meets the load-bearing and tilting requirements by judging the presence or absence of parts. The two distance sensors are respectively coaxially set on the opposite end faces of the bases of the two longitudinal beam automatic tilting devices. The distance sensors are used to measure the real-time distance between the two longitudinal beam automatic tilting devices. By confirming the distance, the two longitudinal beam automatic tilting devices can meet the load-bearing requirements of longitudinal beam lengths of different vehicle models, while avoiding interference between the support surface and the parts to be assembled.

[0019] Working principle

[0020] The magnetic gantry crane lifts the longitudinal beam to directly above the automatic feeding station. The system calculates the theoretical support position of the two automatic longitudinal beam tilting devices based on the type of the longitudinal beam.

[0021] Two automatic longitudinal beam tilting devices move from the previous station (manual loading station) to the automatic feeding station and stop after moving a specified distance. At this time, two distance sensors detect whether the distance between the two automatic longitudinal beam tilting devices is correct and whether the theoretical support position has been reached.

[0022] Once confirmed to be correct, the magnetic gantry crane begins to lower the longitudinal beam onto the two automatic longitudinal beam tilting devices. If incorrect, first adjust the distance between the two automatic longitudinal beam tilting devices to the correct value, and then lower the longitudinal beam onto the two automatic longitudinal beam tilting devices using the magnetic gantry crane.

[0023] At this time, the two automatic longitudinal beam turning devices are in the automatic feeding station. In the initial state of each automatic longitudinal beam turning device, the C-shaped arc turning arm of the longitudinal beam turning device is facing upward, and the longitudinal beam limiting clamping device is in the open state, so that the longitudinal beam can be smoothly placed on the longitudinal beam receiving groove of the two automatic longitudinal beam turning devices.

[0024] After the longitudinal beams are placed, the telescopic cylinders of the two automatic longitudinal beam flipping devices synchronously drive the longitudinal beam telescopic clamping arms to move inward along the Y-axis translation guide slide, pushing the longitudinal beams to translate and finally clamping both sides of the longitudinal beams.

[0025] The proximity switch detects the presence or absence of longitudinal beams; after confirmation, the two automatic longitudinal beam tilting devices start to synchronously drive the forward and reverse motors to move the track wheels to the manual assembly station. During the movement, two distance sensors detect the relative position of the two devices in real time to ensure that they move synchronously.

[0026] At this point, the two automatic longitudinal beam tilting devices are in the manual assembly station. Workers assemble parts on one side of the longitudinal beam. After assembly, the two automatic longitudinal beam tilting devices operate synchronously to drive the tilting motor to rotate in the same direction, causing the longitudinal beam to tilt 90°. Then, parts are assembled on the tilted longitudinal beam. Subsequently, following the same principle, the longitudinal beam is tilted 180° and parts are assembled until the assembly is complete. The longitudinal beam tilting devices are reset to their initial positions, and the longitudinal beam limit clamping device is operated to release the clamping and fixing of the longitudinal beam. The worker then uses a magnetic gantry crane to remove the longitudinal beam and transport it to the next station.

[0027] At this point, the two idle longitudinal beam automatic tilting devices return to the automatic feeding station to pick up the next longitudinal beam, and so on.

[0028] Beneficial effects

[0029] This invention avoids scratches on the longitudinal beams during the assembly process, reduces safety hazards and noise pollution during assembly and rotation, allows adjustment of the support points of the longitudinal beams according to different vehicle models, meets different rotation angle requirements of the longitudinal beams, and enables rapid transfer between the loading station and the assembly station.
