Description

Technical Field

[0001] The present invention relates to the technical field of automobile assembly, and in particular to a transfer and transverse shifting device and a use method thereof. Background Art

[0002] With the vigorous development of the automobile industry, automobile production has gradually increased, and many OEMs need to expand their factories or improve various links in the production process to further increase production capacity. When they do not want to further expand the factory area, but the space in the workshop is limited, the assembly line cannot meet the number of workstations required for assembling vehicles, and the OEM often needs to transfer the vehicle to another assembly line for subsequent assembly.

[0003] During this transfer process, each OEM has two main methods to deal with it. One is to use an overhead crane to move the vehicle in the assembly process from the air to the next workstation to extend the final assembly line, but this method can only be implemented in the early stage of vehicle assembly. In the middle and late stages of assembly, the vehicle has already taken shape, and the weight and hanging points are both difficulties that affect the implementation of this method. The other is to let the vehicle turn by itself and move to the next assembly line to continue assembly. If the vehicle has no steering power and forward power during transfer, additional manpower is needed to provide power to the vehicle, and the distance between the two assembly lines needs to meet the turning radius of the vehicle.

[0004] The Chinese patent document with the publication number CN214691759U discloses a transfer system suitable for the body-in-white of multiple models of automobiles, including a frame assembly, a lifting drive assembly, a vertical slide assembly, a transverse sling, a transverse assembly and a transverse drive assembly, wherein the lifting drive assembly can drive the vertical slide assembly to move vertically along the frame assembly, the vertical slide assembly at least includes a horizontally arranged slide frame, the transverse drive assembly can drive the transverse assembly to move horizontally along the slide frame, the transverse sling includes a boom assembly and a boom drive member, the boom assembly is movably connected to the transverse assembly, the boom drive member can drive the clamping and opening of the boom assembly, and a plurality of predetermined positions of the boom assembly are provided with a sling support block for fixing the body-in-white of automobiles. The utility model can realize fully automatic flexible transfer under the change of the body-in-white size of multiple widths, lengths and heights, and has the characteristics of high flexibility, high efficiency and easy to realize full automation. However, this scheme is not suitable for vehicles in the middle and late stages of assembly, because the body has been assembled in the middle and late stages of assembly, and the boom assembly is no longer convenient to fix the body.

[0077] Example 1

[0078] See also Figure 1-Figure 10 As shown, an embodiment of the present application provides a transfer transverse movement device, including: a frame 1; a first moving device 2, the first moving device 2 is slidably connected to the frame 1 along a first direction; a second moving device 3, the second moving device 3 is slidably connected to the first moving device 2 along a second direction; a wheel clamping device 4, the number of the wheel clamping devices 4 matches the number of wheels of the assembled vehicle, the wheel clamping device 4 is connected to the second moving device 3 through a lifting device 5, and moves up and down under the drive of the lifting device 5; the upper end of the lifting device 5 is slidably connected to the second moving device 2 along the first direction, and the lower end is connected to the wheel clamping device 4.

[0079] In the above embodiment, the first direction is the direction in which the vehicle is to move laterally, and is also the width direction of the vehicle, and the second direction is the length direction of the vehicle.

[0080] The frame 1, as the bearing mechanism of the present invention, is surrounded by a number of columns and beams and has the rigidity to bear the weight of the vehicle. At the same time, it is fixed on the ground without deeply damaging the workshop floor and does not involve civil engineering, thus minimizing the impact on production.

[0081] The number of wheel clamping devices 4 is the same as the number of wheels of the assembled vehicle, and is used to clamp the wheels. The lifting device 5 can not only drive the wheel clamping device 4 to move up and down, but also drive the wheel clamping device 4 to move along the first direction, that is, the width direction of the vehicle, so as to adapt to vehicles of different widths. By moving the second moving device 3 along the second direction, vehicles of different axial lengths can be adapted. After adjusting the positions of the lifting device 5 and the second moving device 3 according to the length and width of the vehicle, the wheels are clamped by the wheel clamping device 4. Then, the vehicle is lifted a certain distance by the lifting device 5. Finally, the first moving device 2 slides on the frame 1 along the first direction to move the assembled vehicle from the A assembly line to the B assembly line, completing the lateral movement of the entire vehicle. The present invention achieves the effect of extending the assembly line and increasing the workstations in a limited space. At the same time, the device has multiple degrees of freedom and can meet the transportation of vehicles of different brands.

[0082] Furthermore, the first movable device 2 includes two first side arms 21 and two first end arms 22, and the two first side arms 21 and the two first end arms 22 form a square; the two first end arms 22 are respectively connected to the two sides of the frame 1 for sliding along the first direction; the second movable device 3 includes two movable arms 31, and the two movable arms 31 are both arranged between the two first end arms 22, and both ends of the two movable arms 31 are connected to the two first side arms 21 for sliding along the second direction; the upper end of at least one jacking device 5 is connected to one of the movable arms 31 for sliding along the first direction.

[0083] This embodiment is described with a vehicle having four wheels. It is understandable that the number of wheel clamping devices 4 is four, and the number of jacking devices 5 is also four accordingly, two of which are slidably connected to the two ends of one of the moving arms 31 along the first direction, and the other two are slidably connected to the two ends of the other moving arm 31 along the first direction.

[0084] By means of two lifting devices 5 moving along the first direction at both ends of a movable arm 31, the width between the two front wheels of the vehicle is adapted. By means of two lifting devices 5 moving along the first direction at both ends of another movable arm 31, the width between the two rear wheels of the vehicle is adapted. By means of two movable arms 31 moving along the second direction on the first side arm 21, the distance between the front and rear wheels of the vehicle is adapted. Through the above arrangement, the wheels of the vehicle in four directions, namely, front, rear, left, and right, are clamped. Next, the vehicle is lifted a certain distance by means of the lifting device 5. Finally, by means of the two first end arms 22 sliding along the first direction on both sides of the frame 1, the assembled vehicle is transversely moved from the A assembly line to the B assembly line, completing the transverse movement of the entire vehicle.

[0085] Furthermore, the two first end arms 22 are driven to slide and be connected to the frame 1 by the first motor 23; the first motor 23 is fixed to the first moving device 2, and the transmission shaft of the first motor 23 is connected to the first pulley 24 arranged at the bottom of the first end arm 22, driving the first pulley 24 to rotate; the first slide rails 11 for sliding the first pulley 24 are arranged on the upper part of both sides of the frame 1 along the first direction.

[0086] Through the above arrangement, the sliding of the two first end arms 22 on the frame 1 along the first direction is achieved, that is, the lateral movement of the entire vehicle is achieved.

[0087] Furthermore, the two movable arms 31 have the same structure, and both include: two second side arms 311 and two second end arms 312; the two second side arms 311 and the two second end arms 312 form a square, and the two second end arms 312 are respectively slidably connected to the two first side arms 21 along the second direction; the lifting device 5 includes a sliding part 51 at the upper end and a lifting part 52 at the lower end, and the sliding part 51 and the lifting part 52 are vertically connected; after the sliding part 51 passes through the space between the two second side arms 311 from bottom to top, the two ends are respectively slidably connected to the two second side arms 311 along the first direction.

[0088] The two second end arms 312 are slidably connected to the two first side arms 21 along the second direction, so that the overall movement of the movable arm 31 is realized to adapt to vehicles with different axial lengths. The two ends of the sliding part 51 are slidably connected to the two second side arms 311 along the first direction, so that the lifting device 5 is moved along the first direction on the movable arm 31 to adapt to vehicles with different widths.

[0089] Furthermore, the two second end arms 312 are driven by the second motor 32 to slide and are connected to the two first side arms 21; the second motor 32 is fixed to the movable arm 31, and the transmission shaft of the second motor 32 is connected to the second pulley 33 arranged at the bottom of the second end arm 31, driving the second pulley 33 to rotate; the upper parts of the two first side arms 21 are both provided with a second slide rail 211 along the second direction for the second pulley 33 to slide.

[0090] Through the above arrangement, the sliding of the movable arm 31 on the first side arm 21 along the second direction is achieved.

[0091] Furthermore, the sliding part 51 is slidably connected to the second side arm 311 through the first driving device 6; the first driving device includes a first support base 61, a second support base 62, a third motor 63 and a first lead screw 64; the first support base 61 and the second support base 62 are both fixed on the second moving device 3, and are arranged on both sides of the sliding part 51 along the first direction; the third motor 63 is fixed on the first support base 61; the first end of the first lead screw 64 is drivingly connected to the third motor 63, and rotates under the drive of the third motor 63, and the second end of the first lead screw 64 is rotationally connected to the first support base 61, the middle part of the sliding part 51 and the second support base 62 in turn, and is screwed to the inside of the sliding part 51.

[0092] Two support bases are supported at both ends of the first lead screw 64 to provide support for the rotation of the first lead screw 64. The first end of the first lead screw 64 is connected to the third motor 63 through a coupling 65, and the third motor 63 drives the first lead screw 64 to rotate through the coupling 65. Since the first lead screw 64 is screwed to the middle of the sliding part 51, the rotation of the first lead screw 64 drives the sliding part 51 to move along the first direction.

[0093] It can be understood that the first lead screw 64 is located in the middle of the two second side arms 311 to achieve the same moving speed at both ends of the sliding portion 51 .

[0094] Furthermore, a sliding block 314 is disposed on the upper portion of each of the two second side arms 311 , and a third sliding groove 315 cooperating with the sliding block 314 is disposed on the bottom of both ends of the sliding portion 51 .

[0095] Furthermore, the wheel clamping device 4 includes a lifting arm 41, a connecting arm 42 and a wheel clamping portion 43; the first end of the lifting arm 41 is connected to the upper end of the connecting arm 42, and the second end is connected to the lifting portion 52 by sliding up and down through the second driving device 7; the wheel clamping portion 43 is connected to the lower end of the connecting arm 42 for clamping the wheel.

[0096] The up-and-down movement of the upper lifting arm 41 drives the wheel clamping portion 43 at the lower end to move up and down, thereby lifting the entire vehicle to a certain height.

[0097] Furthermore, a platform 53 is arranged at the bottom of the lifting part 52, and at least two columns 54 are arranged on the edge of the platform 53; the second end of the lifting arm 41 is placed in the space enclosed by the platform 53 and the columns 54; the second driving device 7 includes a fourth motor 71 and a second lead screw 72; the fourth motor 71 is fixed on the platform 53; the lower end of the second lead screw 72 is drivingly connected to the fourth motor 71, and rotates under the drive of the fourth motor 71, and the upper end of the second lead screw 72 is screwed to the bottom of the second end of the lifting arm 41.

[0098] In this embodiment, the platform 53 is square, and a column 54 is set at each of the four vertices of the edge. The platform 53 and the four columns 54 enclose a hollow square column, and the second end of the lifting arm 41 and the second driving device are both set inside the column. Since the lifting part 52 at the lower end is square, the sliding part 51 at the upper end includes a first sliding arm 511 and a second sliding arm 512, and the first sliding arm 511 and the second sliding arm 512 are respectively connected to the two ends of the upper part of the lifting part 52, and the second end of the first lead screw 64 is rotatably connected to the first support base 61, the middle part of the first sliding arm 511, the middle part of the second sliding arm 512 and the second support base 62 in sequence, and is screwed to the inside of the sliding part 51. The advantage of this arrangement is that the first lead screw 64 has a more stable driving force on the lifting device 5.

[0099] Specifically, the fourth motor 71 is fixed to the platform 53 via a motor base 73, the motor base 73 is fixed to the platform 53, and the fourth motor 71 is mounted on the motor base 73. The fourth motor 71 drives the second lead screw 72 to rotate, and since the upper end of the second lead screw 72 is screwed to the bottom of the second end of the jacking arm 41, the rotation of the second lead screw 72 drives the jacking arm 41 to move up and down, thereby realizing the overall upward movement of the wheel clamping device 4.

[0100] It can be understood that the length of the connecting arm 42 minus the lifting height is greater than the height of the highest brand of vehicle produced to accommodate all brands of vehicles.

[0101] Furthermore, a fourth sliding groove 44 is provided on the outer side surface of the second end of the lifting arm 41 for sliding up and down along the column 54 .

[0102] The fourth slide groove 44 forms a slide rail mechanism, and four fourth slide grooves 44 are provided corresponding to the number of the columns 54. The fourth slide groove 44 is specifically composed of 16 outer steel plates 441 and 12 inner steel plates 442 fixed to the outer side surface of the lifting arm 41 by bolt connection.

[0104] The number and shape of the bracket 432 can be designed according to the size and shape of the wheel. In this embodiment, two brackets 432 are provided, which are arranged perpendicular to the clamping platform 431 and symmetrically connected to the two ends of the clamping platform 431 to fit the front and rear sides of the wheel. The shape is designed to be a triangular cone so as to have a better fit with the wheel and better clamp the wheel.

[0105] The clamping platform 431 is provided with an internal cavity, and the two supporting arms 432 slide in the cavity along the second direction. By sliding the supporting arms 432, the distance between the two supporting arms 432 can be adjusted to be suitable for wheel radius of various brands. The relative movement of the two is limited by the bolt 433.

[0106] Furthermore, the first end of the support arm 432 is slidably connected to the inside of the clamping platform 431 through the adjusting wheel 434 and the screw 435 ; the first end of the screw 435 is screwed to the adjusting wheel 434 , and the second end is connected to the first end of the support arm 432 .

[0107] The adjusting wheel 434 is arranged outside the two ends of the clamping platform 431, and the screw 435 is arranged inside the clamping platform 431, and its axial direction is arranged along the second direction. Turning the adjusting wheel 434 drives the screw 435 to push or pull the support arm 432 along the second direction, thereby realizing the movement of the support arm 432 in the clamping platform 431.

[0108] Furthermore, the clamping platform 431 includes a bottom plate 4311 and a vertical plate 4312, the vertical plate 4312 is vertically connected to the middle position of the upper part of the bottom plate 4311, and separates the bottom plate 4311 into a first side and a second side; a plug block 436 is provided at the first end of the support arm 432, and the plug block 436 passes through the through hole 4313 opened at the lower part of the vertical plate 4312 from the first side of the bottom plate 4312 and enters the second side of the bottom plate 4312, and the plug block 436 opens a first connecting hole 4361 that passes through the upper and lower parts; a plurality of second connecting holes 4314 are arranged along the second direction at the corresponding position of the plug block 436 on the second side of the bottom plate 4311; the plug 433 fixes the support arm 432 by connecting the first connecting hole 4361 and the second connecting hole 4314.

[0109] The plug block 436 is connected to the first end of the support arm 432, and the support arm 432 slides in the through hole 4313 when the support arm 432 moves inside the clamping platform 431. It can be understood that, corresponding to the two support arms 432, one through hole 4313 is set at each end of the lower part of the vertical plate 4312.

[0110] The second connecting holes 4314 at different hole positions correspond to the plug blocks 436 adjusted to different positions, and different types of wheel clamping widths can be accommodated by changing the hole positions of the second connecting holes 4314 .

[0112] Example 2

[0113] See also Figure 6 , Figure 7 and Fig.11 This embodiment provides a transfer transverse shifting device. Different from the embodiment 1, the transfer transverse shifting device further includes a warning device 8; the warning device 8 includes a bracket 81, a numbering plate 82, two threshold switches, namely a first threshold switch 83 and a second threshold switch 84, and two limit switches, namely a first limit switch 85 and a second limit switch 86;

[0114] The bracket 81 is fixed to the upper part of the platform 53;

[0115] The first limit switch 85 and the second limit switch 86 are respectively fixed to the upper and lower ends of the bracket 81, the first threshold switch 83 and the second threshold switch 84 are both fixed to the bracket 81, and are both located between the first limit switch 85 and the second limit switch 86, the first threshold switch 83 is arranged close to the first limit switch 85, and the second threshold switch 84 is arranged close to the second limit switch 86;

[0116] The first end of the numbering plate 82 is sleeved and screwed on the second lead screw 72, and the second end is located at the middle position of the first threshold switch 83 and the second threshold switch 84, and is connected to the bracket 81 for upward and downward movement; a sensor is arranged at the second end of the numbering plate 82, and the sensor is electrically connected to the first threshold switch 83, the second threshold switch 84, the first limit switch 85 and the second limit switch 86 respectively, and the sensor is used to monitor the distance between the numbering plate 82 and the first threshold switch 83, the first threshold switch 84, the first limit switch 85 and the second limit switch 86;

[0117] When the distance between the issuing plate 82 and the first threshold switch 83 and the second threshold switch 84 reaches a first preset distance, the alarm circuit is turned on to issue an alarm reminder, and when the distance between the first limit switch 85 and the first limit switch 86 reaches a second preset distance, the power supply circuit of the fourth motor 71 is disconnected.

[0118] It can be understood that the first threshold switch 83 and the second threshold switch 84 are electrically connected to the alarm circuit, and the first limit switch 85 and the second limit switch 86 are electrically connected to the power supply circuit of the fourth motor 71 .

[0119] In order to control the displacement of the vehicle when it is lifted or lowered and prevent accidents, a warning device 8 is provided. When the fourth motor 71 drives the second lead screw 72 to rotate, it also drives the number plate 82 to move up and down, that is, the number plate 82 rises or falls synchronously with the vehicle.

[0120] Ascending process: the numbering plate 82 starts to rise from the middle position between the first threshold switch 83 and the second threshold switch 84. When the sensor detects that the distance between the numbering plate 82 and the first threshold switch 83 reaches the first preset distance, the sensor transmits a signal to the first threshold switch 83, and the first threshold switch 83 turns on the alarm circuit to sound an alarm to remind the operator that the displacement is about to reach the threshold; when the sensor detects that the numbering plate 82 and the first limit switch 85 reach the second preset distance, the sensor transmits a signal to the first limit switch 85, and the first limit switch 85 disconnects the power supply circuit of the fourth motor 71, limiting the jacking device 5 from continuing to rise.

[0121] Descending process: the numbering plate 82 starts to descend from the middle position of the first threshold switch 83 and the second threshold switch 84. When the sensor detects that the distance between the numbering plate 82 and the second threshold switch 84 reaches the first preset distance, the sensor transmits a signal to the second threshold switch 84, and the second threshold switch 84 turns on the alarm circuit to sound an alarm to remind the operator that the displacement is about to reach the threshold; when the sensor detects that the numbering plate 82 and the second limit switch 86 reach the second preset distance, the sensor transmits a signal to the second limit switch 86, and the second limit switch 86 disconnects the power supply circuit of the fourth motor 71, limiting the jacking device 5 from continuing to descend.

[0122] Furthermore, the bracket 81 includes a base 811, a first bracket plate 812 and a second bracket plate 813; the base 811 is fixed to the upper part of the platform 53; the first bracket plate 812 and the second bracket plate 813 are arranged on the upper part of the base 811 and are perpendicular to each other; the first bracket plate 812 is arranged perpendicular to the numbering plate 82, and the first bracket plate 812 has a sliding hole 814 in the vertical direction, and the second end of the numbering plate 82 passes through the sliding hole 814, and the numbering plate 82 slides in the sliding hole 814; the first threshold switch 83, the second threshold switch 84, the first limit switch 85 and the second limit switch 86 are all fixed on the second bracket plate 813.

[0123] When the numbering plate 82 is driven to rise or fall by the second lead screw 72, the second end of the numbering plate 82 slides in the sliding hole 814. Since the first threshold switch 83, the second threshold switch 84, the first limit switch 85 and the second limit switch 86 are all fixed on the second bracket plate 813, the first bracket plate 812 and the second bracket plate 813 are vertically arranged, so that the sensor can more conveniently monitor the distance between the numbering plate 82 and the above switches.
