Description

Technical Field

[0001] This utility model belongs to the technical field of front-end module assembly of passenger vehicles, and specifically relates to a gripping and lifting device for the front-end module assembly of passenger vehicles. Background Technology

[0002] The existing grabbing and lifting devices for the front-end module assembly of passenger vehicles mostly use cylinders to control two hooks to clamp the front-end module assembly. Then, a crane (such as a gantry crane or lifting hoist) is used to lift and transport the clamped front-end module assembly to the transfer equipment, and then the two hooks are controlled to release the front-end module assembly.

[0003] When hoisting the front-end module assembly onto the transfer equipment, it is necessary to accurately lower the front-end module assembly to the preset position on the transfer equipment. In order to ensure that the landing point of the front-end module assembly on the transfer equipment is accurate, it is necessary to ensure that the front-end module assembly does not shake or tilt during the hoisting and transportation process.

[0004] However, the existing grabbing and lifting devices for the front-end module assembly of passenger vehicles are prone to having excessive vertical gaps between the hook ends and the workpiece after the two hooks clamp the front-end module assembly. This means that during the subsequent lifting of the front-end module assembly by a crane, the front-end module assembly is actually only clamped on the two hooks, but not hooked onto them. This can easily cause swaying and tilting, affecting the landing point positioning of the front-end module assembly on the transfer equipment, and even causing it to fall and lead to safety accidents. Utility Model Content

[0005] This utility model provides a gripping and lifting device for the front-end module assembly of a passenger vehicle, solving the problem that existing gripping and lifting devices for the front-end module assembly of passenger vehicles often have excessive vertical gaps between the hook ends and the workpiece after the two hooks clamp the front-end module assembly. This results in the front-end module assembly being merely clamped on the two hooks without being hooked, making it prone to swaying and tilting. This can affect the landing point positioning of the front-end module assembly on the transfer equipment and even cause it to fall, leading to safety accidents.

[0006] The technical solution adopted by this utility model is: a gripping and lifting device for the front module assembly of a passenger vehicle, comprising: a hanger, two hangers symmetrically arranged on the hanger, and a drive unit installed on the hanger; Both of the aforementioned booms are vertically arranged, both of the aforementioned booms are slidably connected to the hanger, both of the aforementioned booms are capable of translation in a plane perpendicular to the front-back direction, and the bottom end of the boom extends to the bottom of the hanger; Both of the lifting rods have hooks extending from their bottom ends, and both hooks extend inward; the two lifting rods are respectively used to pass through the left and right lifting holes on the upper crossbeam of the front module assembly to move the two hooks to the underside of the upper crossbeam; The drive unit is used to drive the two booms to move closer and rise synchronously in the left-right direction, or to drive the two booms to move further away and fall synchronously in the left-right direction.

[0007] After passing the two lifting rods through the left and right lifting holes on the upper crossbeam of the front module assembly, respectively, and moving the two hooks to the lower side of the upper crossbeam, the driving unit drives the two lifting rods to approach and rise synchronously in the left-right direction. This reduces the vertical gap between the upper surface of the hooks and the workpiece (the lower surface of the upper crossbeam) while the two lifting rods clamp the front module assembly. This prevents the front module assembly from shaking, tilting, or falling during the lifting and transporting process using the grabbing and lifting device for the front module assembly of the passenger vehicle provided by this utility model, thereby ensuring accurate positioning of the front module assembly when it lands on the transfer equipment.

[0008] Furthermore, the drive unit includes a drive mechanism mounted on the hanger, and two guide mechanisms fixedly connected to the lower side of the hanger, the two guide mechanisms being arranged symmetrically on the left and right sides; The guide mechanism is installed on the lower side of the hanger, and the hanger rod is slidably connected to the guide mechanism on the same side. The guide mechanism is used to restrict the hanger rod on the same side to translate only in a plane perpendicular to the front and rear direction. The drive mechanism is used to drive the two booms to move closer and rise synchronously in the left-right direction, or to drive the two booms to move further away and fall synchronously in the left-right direction.

[0009] By restricting the two guide mechanisms to allow the booms on the same side to translate only in a plane perpendicular to the front-back direction, the booms can be effectively prevented from tilting when the two booms clamp the front module assembly, thereby preventing the clamped front module assembly from tilting.

[0010] Furthermore, the guiding mechanism includes a first linear slide rail, a second linear slide rail, and a sliding block; The first linear slide rail is fixedly installed on the lower side of the hanger, and the sliding block is slidably connected to the first linear slide rail. The sliding block can slide back and forth linearly in the left and right direction on the first linear slide rail. The second linear slide rail is fixedly connected to the sliding block, and the hanger rod is slidably connected to the second linear slide rail on the same side. The hanger rod can slide back and forth linearly in the vertical direction on the second linear slide rail.

[0011] Furthermore, the hanger is in the shape of a horizontal plate; The hanger has two through mounting holes, which are symmetrically arranged from left to right. The top end of the hanger rod passes through the mounting hole on the same side to the upper side of the hanger. The hanger rod can move back and forth in a straight line along the left and right direction in the mounting hole on the same side. The drive mechanism includes two drive components symmetrically arranged on the upper side of the hanger. Each drive component includes a cylinder, a rotating shaft, and a first guide plate. The first guide plate is vertically arranged and parallel to the left-right direction; the first guide plate has a first arc-shaped hole that runs through the front and back; the fixed end of the cylinder is hinged to the hanger, and the telescopic end of the cylinder is hinged to the top of the hanger rod on the same side through the rotating shaft; the rotating shaft is horizontally arranged in the front-back direction, and one end of the rotating shaft passes through the first arc-shaped hole; the rotating shaft cooperates with the first arc-shaped hole; the central axis of the first arc-shaped hole on the first guide plate gradually tilts from bottom to top toward the other first guide plate.

[0012] By pulling the rotating shaft along the central axis of the first arc-shaped hole using the cylinder, the top end of the boom on the same side can be moved along the central axis of the first arc-shaped hole. With the cooperation of the guide mechanism on the same side, the function of driving the boom on the same side to move along the central axis of the first arc-shaped hole in a plane perpendicular to the front and back direction can be realized.

[0013] Furthermore, the drive component also includes a second guide plate; The first guide plate and the second guide plate are symmetrically arranged front and back, and the top of the boom on the same side and the telescopic end of the cylinder on the same side are both located between the first guide plate and the second guide plate; The second guide plate has a second arc-shaped hole that runs through the front and back, corresponding to the first arc-shaped hole; One end of the rotating shaft passes through the first arc-shaped hole and extends to the outside of the first guide plate, while the other end of the rotating shaft passes through the second arc-shaped hole and extends to the outside of the second guide plate.

[0014] By setting the second guide plate, one end of the rotating shaft extends through the first arc-shaped hole to the outside of the first guide plate, and the other end of the rotating shaft extends through the second arc-shaped hole to the outside of the second guide plate, the stability of the rotating shaft when the cylinder pulls it to move horizontally can be effectively improved.

[0015] Furthermore, the gripping device for the front-end module assembly of the passenger vehicle also includes two hinge seats, which are symmetrically arranged on the left and right sides. The hinge seats are fixedly connected to the upper side of the hanger, and the fixed end of the cylinder is hinged to the hinge seat on the same side.

[0016] Furthermore, a lifting ring is fixedly connected to the upper side of the hanger.

[0017] Furthermore, the gripping device for the front-end module assembly of the passenger vehicle also includes two positioning components symmetrically arranged on the hanger; the positioning components include a vertically arranged positioning rod and a positioning pin, the positioning rod is fixedly connected to the hanger, the top end of the positioning pin is fixedly connected to the bottom end of the positioning rod, and the outer diameter of the positioning pin is smaller than the outer diameter of the positioning rod. The two positioning pins are used to engage with the left positioning hole and the right positioning hole on the upper crossbeam, respectively. The bottom end of the positioning rod is provided with a positioning surface, which is used to fit and position itself against the upper surface of the upper crossbeam. The two positioning pins are used to insert into the left and right positioning holes on the upper crossbeam when the two lifting rods pass through the left and right lifting holes respectively.

[0018] By setting two positioning pins, which, when the two lifting rods pass through the left and right lifting holes respectively, are respectively inserted into the left and right positioning holes on the upper crossbeam, the two lifting rods can be positioned in the left-right direction. Furthermore, by providing positioning surfaces at the bottom of the positioning rods, after the two positioning pins are inserted into the left and right positioning holes respectively, the two positioning surfaces are fitted against the upper surface of the upper crossbeam, thereby achieving the vertical positioning of the two lifting rods. This completes the connection between the front-end module assembly and the two lifting rods. Positioning between rods: By pre-calibrating the dimensions of each component (the lifting rod, the positioning rod, and the positioning pin), it can be ensured that after the positioning between the front-end module assembly and the two lifting rods is completed, the two lifting rods are driven by the drive unit to approach and rise synchronously in the left and right directions. This ensures that while clamping the front-end module assembly, the vertical gap between the upper surface of the hook and the workpiece (the lower surface of the upper crossbeam) is not greater than the maximum allowable gap value, reducing errors caused by manual adjustment. It has the advantages of simple positioning operation, high positioning accuracy, and no need for manual adjustment.

[0019] Furthermore, a first guide cone surface is provided on the outer periphery of the bottom end of the positioning pin.

[0020] Furthermore, a second guide cone surface is provided on the outer periphery of the bottom end of the hook portion.

[0021] Furthermore, the grabbing device for the front-end module assembly of the passenger vehicle also includes a U-shaped handle, which is hinged to the upper side of the hanger. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] like Figures 1 to 3 As shown, this embodiment provides a gripping and lifting device for the front-end module assembly of a passenger vehicle, including: a hanger 1, two symmetrically arranged rods 2 on the hanger 1, and a drive unit installed on the hanger 1; Both of the aforementioned suspension rods 2 are vertically arranged, both of the aforementioned suspension rods 2 are slidably connected to the suspension frame 1, both of the aforementioned suspension rods 2 are capable of translation in a plane perpendicular to the front-back direction, and the bottom end of the suspension rod 2 extends to the bottom of the suspension frame 1; The bottom ends of both of the two lifting rods 2 are extended with hook portions 2.1, and both hook portions 2.1 extend inward; the two lifting rods 2 are respectively used to pass through the left lifting hole 3.1 and the right lifting hole 3.2 on the upper crossbeam 3 of the front module assembly, so as to move the two hook portions 2.1 to the lower side of the upper crossbeam 3; The drive unit is used to drive the two booms 2 to move closer and rise synchronously in the left and right directions, or to drive the two booms 2 to move further away and fall synchronously in the left and right directions.

[0026] After passing the two lifting rods 2 through the left lifting hole 3.1 and right lifting hole 3.2 on the upper crossbeam 3 of the front module assembly, respectively, and moving the two hook parts 2.1 to the lower side of the upper crossbeam 3, the driving unit drives the two lifting rods 2 to approach and rise synchronously in the left and right directions. This reduces the vertical gap between the upper surface of the hook part 2.1 and the workpiece (the lower surface of the upper crossbeam 3) while the two lifting rods 2 clamp the front module assembly. This prevents the front module assembly from shaking, tilting, or falling during the lifting and transporting process using the grabbing and lifting device for the front module assembly of the passenger vehicle provided by this utility model, thus ensuring accurate positioning of the front module assembly when it lands on the transfer equipment.

[0027] In one embodiment, the drive unit includes a drive mechanism mounted on the hanger 1 and two guide mechanisms fixedly connected to the lower side of the hanger 1, the two guide mechanisms being arranged symmetrically on the left and right. The guide mechanism is installed on the lower side of the hanger 1, and the hanger rod 2 is slidably connected to the guide mechanism on the same side. The guide mechanism is used to restrict the hanger rod 2 on the same side to translate only in a plane perpendicular to the front and rear directions. The drive mechanism is used to drive the two booms 2 to move closer and rise synchronously in the left and right directions, or to drive the two booms 2 to move further away and fall synchronously in the left and right directions.

[0028] By restricting the two guide mechanisms to allow the same-side booms 2 to translate only in a plane perpendicular to the front-back direction, the booms 2 can be effectively prevented from tilting when they clamp the front-end module assembly, thus avoiding the clamped front-end module assembly from tilting.

[0029] Specifically, in this embodiment, such as Figure 1As shown, the guiding mechanism includes a first linear slide rail 4, a second linear slide rail 5, and a sliding block 6; The first linear slide rail 4 is fixedly installed on the lower side of the hanger 1, and the sliding block 6 is slidably connected to the first linear slide rail 4.

The top end of the hanger rod 2 passes through the mounting hole on the same side to the upper side of the hanger 1. The hanger rod 2 can move back and forth in a straight line along the left and right direction in the mounting hole on the same side. The drive mechanism includes two drive components symmetrically arranged on the upper side of the hanger 1. The drive components include a cylinder 7, a rotating shaft 8, and a first guide plate 9.

[0031] By pulling the rotating shaft 8 along the central axis of the first arc-shaped hole using the cylinder 7, the top end of the rod 2 on the same side can be moved along the central axis of the first arc-shaped hole. With the cooperation of the guide mechanism on the same side, the function of driving the rod 2 on the same side to move along the central axis of the first arc-shaped hole in a plane perpendicular to the front and back direction can be realized.

[0032] Specifically, in this embodiment, such as Figure 1 As shown, the drive assembly also includes a second guide plate 10; The first guide plate 9 and the second guide plate 10 are symmetrically arranged front and back, and the top of the rod 2 on the same side and the telescopic end of the cylinder 7 on the same side are both located between the first guide plate 9 and the second guide plate 10. The second guide plate 10 has a second arc-shaped hole that runs through the front and back, corresponding to the first arc-shaped hole; One end of the rotating shaft 8 extends through the first arc-shaped hole to the outside of the first guide plate 9, and the other end of the rotating shaft 8 extends through the second arc-shaped hole to the outside of the second guide plate 10.

[0033] By setting the second guide plate 10, one end of the rotating shaft 8 extends through the first arc-shaped hole to the outside of the first guide plate 9, and the other end of the rotating shaft 8 extends through the second arc-shaped hole to the outside of the second guide plate 10, the stability of the rotating shaft 8 when the cylinder 7 pulls it to translate can be effectively improved.

[0034] Preferably, in this embodiment, such as Figure 1 As shown, the grabbing and lifting device of the front module assembly of the passenger vehicle also includes two hinge seats 11. The two hinge seats 11 are arranged symmetrically on the left and right sides. The hinge seats 11 are fixedly connected to the upper side of the hanger 1. The fixed end of the cylinder 7 is hinged to the hinge seat 11 on the same side.

[0035] Preferably, in this embodiment, such as Figure 1 and Figure 3 As shown, a lifting ring 12 is fixedly connected to the upper side of the hanger 1.

[0036] Preferably, in this embodiment, such as Figure 1 and Figure 3 As shown, the grabbing and lifting device of the front module assembly of the passenger vehicle also includes two positioning components symmetrically arranged on the hanger 1; the positioning components include a vertically arranged positioning rod 13 and a positioning pin 14, the positioning rod 13 is fixedly connected to the hanger 1, the top end of the positioning pin 14 is fixedly connected to the bottom end of the positioning rod 13, and the outer diameter of the positioning pin 14 is smaller than the outer diameter of the positioning rod 13. The two positioning pins 14 are used to engage with the left positioning hole 3.3 and the right positioning hole 3.4 on the upper crossbeam 3, respectively. The bottom end of the positioning rod 13 is provided with a positioning surface, which is used to fit and position itself against the upper surface of the upper crossbeam 3. The two positioning pins 14 are used to pass through the left positioning hole 3.3 and the right positioning hole 3.4 on the upper crossbeam 3 when the two lifting rods 2 pass through the left lifting hole 3.1 and the right lifting hole 3.2 respectively.

[0037] By setting two positioning pins 14, when the two lifting rods 2 pass through the left lifting hole 3.1 and the right lifting hole 3.2 respectively, they also pass through the left positioning hole 3.3 and the right positioning hole 3.4 on the upper crossbeam 3, thus achieving the positioning of the two lifting rods 2 in the left-right direction. Furthermore, by setting a positioning surface at the bottom end of the positioning rod 13, after the two positioning pins 14 are inserted into the left positioning hole 3.3 and the right positioning hole 3.4 respectively, the two positioning surfaces are then fitted against the upper surface of the upper crossbeam 3, thus achieving the positioning of the two lifting rods 2 in the up-down direction, thereby completing the positioning of the front end mold. Positioning between the front module assembly and the two lifting rods 2: By pre-calibrating the dimensions of each component (the lifting rod 2, the positioning rod 13, and the positioning pin 14), it can be ensured that after the positioning between the front module assembly and the two lifting rods 2 is completed, the two lifting rods 2 are driven by the drive unit to approach and rise synchronously in the left and right directions. This ensures that while clamping the front module assembly, the vertical gap between the upper surface of the hook part 2.1 and the workpiece (the lower surface of the upper crossbeam 3) is not greater than the maximum allowable gap value, reducing errors caused by manual adjustment. It has the advantages of simple positioning operation, high positioning accuracy, and no need for manual adjustment.

[0039] Preferably, in this embodiment, such as Figure 1 As shown, a second guide cone surface 2.1.1 is provided on the outer periphery of the bottom end of the hook portion 2.1.

[0040] Preferably, in this embodiment, such as Figure 1 and Figure 3 As shown, the grabbing device of the front module assembly of the passenger vehicle also includes a U-shaped handle 15, which is hinged to the upper side of the hanger 1.

[0041] The grabbing and lifting device for the front-end module assembly of passenger vehicles provided by this utility model has at least the following technical effects or advantages: 1. After passing the two lifting rods 2 through the left lifting hole 3.1 and right lifting hole 3.2 on the upper crossbeam 3 of the front module assembly, respectively, and moving the two hook parts 2.1 to the lower side of the upper crossbeam 3, the driving unit drives the two lifting rods 2 to approach and rise synchronously in the left and right directions. This reduces the vertical gap between the upper surface of the hook part 2.1 and the workpiece (the lower surface of the upper crossbeam 3) while the two lifting rods 2 clamp the front module assembly. This prevents the front module assembly from shaking, tilting, or falling during the lifting and transporting process using the grabbing and lifting device for the front module assembly of the passenger vehicle provided by this utility model, thereby ensuring accurate positioning of the front module assembly when it lands on the transfer equipment.

[0042] 2. By restricting the two guide mechanisms to allow the same-side booms 2 to translate only in a plane perpendicular to the front-back direction, the booms 2 can be effectively prevented from tilting when they clamp the front-end module assembly, thereby avoiding the occurrence of tilting of the clamped front-end module assembly.

[0043] 3. By pulling the rotating shaft 8 along the central axis of the first arc-shaped hole through the cylinder 7, the top end of the rod 2 on the same side can be moved along the central axis of the first arc-shaped hole. With the cooperation of the guide mechanism on the same side, the function of driving the rod 2 on the same side to move along the central axis of the first arc-shaped hole in a plane perpendicular to the front and back direction can be realized.

[0044] 4. By setting the second guide plate 10, one end of the rotating shaft 8 extends through the first arc-shaped hole to the outside of the first guide plate 9, and the other end of the rotating shaft 8 extends through the second arc-shaped hole to the outside of the second guide plate 10, the stability of the rotating shaft 8 when the cylinder 7 pulls it to move is effectively improved.

[0045] 5. By setting two positioning pins 14, when the two lifting rods 2 pass through the left lifting hole 3.1 and the right lifting hole 3.2 respectively, they also pass through the left positioning hole 3.3 and the right positioning hole 3.4 on the upper crossbeam 3, thus achieving the positioning of the two lifting rods 2 in the left-right direction. Furthermore, by setting a positioning surface at the bottom end of the positioning rod 13, after the two positioning pins 14 are inserted into the left positioning hole 3.3 and the right positioning hole 3.4 respectively, the two positioning surfaces are then fitted against the upper surface of the upper crossbeam 3, thus achieving the positioning of the two lifting rods 2 in the up-down direction, thereby completing the positioning of the front end... Positioning between the module assembly and the two lifting rods 2: By pre-calibrating the dimensions of each component (the lifting rod 2, the positioning rod 13, and the positioning pin 14), it can be ensured that after the positioning between the front module assembly and the two lifting rods 2 is completed, the two lifting rods 2 are driven by the drive unit to move closer and rise synchronously in the left and right directions. This ensures that while clamping the front module assembly, the vertical gap between the upper surface of the hook part 2.1 and the workpiece (the lower surface of the upper crossbeam 3) is not greater than the maximum allowable gap value, reducing errors caused by manual adjustment. It has the advantages of simple positioning operation, high positioning accuracy, and no need for manual adjustment.
