Description

Technical Field

[0001] The invention relates to the technical field of automobile assembly, in particular to a vehicle body assembly. Background Art

[0002] Automotive assembly is the process of welding together the underbody parts, side parts, roof beams, roof and other parts to form the body in white (body after welding but before painting). Automotive assembly plays a vital role in the automobile manufacturing process. It involves the assembly and welding of the body in white, ensuring that the various parts are properly connected to form a complete body structure. This process requires precise positioning and high-quality welding to ensure the strength and safety of the body.

[0003] The existing assembly methods include flexible assembly, OPENGATE assembly and assembly of two independent white bodies. Among them, the disadvantages of flexible assembly are: the single row, half row and double row are designed and manufactured as independent grippers, but they only share a fixed frame, or there is no fixed frame, and the robot grabs each dedicated gripper, and the grippers are combined together through a fixed frame, or the grippers are connected and combined together without a frame, so as to solve the problems of robot load and welding accessibility. This tooling method of corresponding a dedicated gripper to each vehicle model occupies a large area, has a large investment, and has poor gripper rigidity and dimensional stability. The shortcomings of OPENGATE assembly: the single row, half row, and double row are designed and manufactured as independent assembly fixture parts, stored in their own dedicated areas, and the fixtures are moved in and out in sequence through the fixture slide rails to enter the assembly station to switch between different models. It takes up a huge fixture storage space as a fixture library, and at the same time, it takes up a huge fixture switching space to achieve the back and forth movement in and out switching and combination of single row, half row, and double row fixtures. It faces huge space and investment problems and is rarely used in the light truck industry. The shortcomings of using two independent white body assembly fixtures: the single row / half row is designed and manufactured as a dedicated independent body assembly fixture, and the double row is also designed and manufactured as a dedicated independent body assembly fixture. The two assembly fixtures have independent sites and welding equipment. Simply put, two independent assembly fixtures are manufactured. When one model is produced, the fixtures and equipment of the other model are idle, occupying double the space and investment.

[0004] Therefore, there is an urgent need for a vehicle body assembly that can meet the functions of single-row / half-row and double-row vehicle body assembly and has high equipment and site utilization. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a body assembly, aiming to solve the problem in the prior art that there is a lack of a body assembly that can meet the functions of single-row / one-and-a-half-row and double-row body assembly and has high equipment and site utilization.

[0006] The vehicle body assembly proposed in the present invention includes a first positioning component, a second positioning component, a split-and-joint positioning component for connecting the first positioning component and the second positioning component, and a driving device for driving the second positioning component. The first positioning component is used for single-row / half-row vehicle assembly, and the first positioning component and the second positioning component are used together for double-row vehicle assembly. The first positioning component and the second positioning component are connected or separated by the split-and-joint positioning component to meet the production requirements of single-row, half-row or double-row vehicles.

[0007] The above-mentioned vehicle body assembly is provided with a first positioning component and a second positioning component, and the first positioning component is a single-row / half-row positioning component, and the second positioning component is a double-row positioning component, so that the vehicle body assembly can respectively realize the assembly functions of single-row, half-row and double-row vehicles, and then by providing a split positioning component and a driving device, the second positioning component and the first positioning component can be connected or separated. When it is necessary to assemble a single-row or half-row vehicle, the second positioning component is driven to move away from the first positioning component. When it is necessary to assemble a double-row vehicle, the second positioning component is driven to move close to and connect to the first positioning component, and cooperate with the first positioning component to realize the assembly of the double-row vehicle. Then, through such a setting, a set of fixtures can be reasonably used for the assembly of different types of vehicles, without the need to set up multiple sets of fixtures, thereby reducing costs. When switching modes, there is no need to repeatedly store or switch the fixtures, and only the position of the second positioning component needs to be moved, which greatly reduces the space occupied by the equipment and improves the space utilization rate. Therefore, the present invention solves the problem in the prior art that there is a lack of a vehicle body assembly that not only meets the single-row / half-row and double-row vehicle body assembly functions, but also has high equipment and site utilization rates.

[0030] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0031] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] See also Figures 1 to 10 , shown is the overall assembly of a vehicle body in an embodiment of the present invention, including a first positioning component 10, a second positioning component 20, a separation and combination positioning component 30 for connecting the first positioning component 10 and the second positioning component 20, and a driving device 40 for driving the second positioning component 20. The first positioning component 10 is used for single-row / half-row vehicle assembly, and the first positioning component 10 and the second positioning component 20 are used for double-row vehicle assembly. The first positioning component 10 and the second positioning component 20 are connected or separated by the separation and combination positioning component 30 to meet the production requirements of single-row, half-row or double-row vehicles.

[0035] It can be understood that by setting the first positioning component 10 and the second positioning component 20, and the first positioning component 10 is a single-row / half-row positioning component, and the second positioning component 20 is a double-row positioning component, the vehicle body assembly can realize the assembly functions of single-row, half-row and double-row vehicles respectively, and then by setting the split-and-joint positioning component 30 and the driving device 40, the second positioning component 20 and the first positioning component 10 can be connected or separated. When it is necessary to assemble a single-row or half-row vehicle, the second positioning component 20 is driven to move away from the first positioning component 10. When it is necessary to assemble a double-row vehicle, the second positioning component 20 is driven to move close to and connect to the first positioning component 10, and cooperate with the first positioning component 10 to realize the assembly of the double-row vehicle. Then, through such a setting, a set of fixtures can be reasonably used for assembly of different types of vehicles, without setting up multiple sets of fixtures, thereby reducing costs. When switching modes, there is no need to repeatedly store or switch the fixtures, and only the position of the second positioning component 20 needs to be moved, which greatly reduces the space occupied by the equipment and improves space utilization. Therefore, the present invention solves the problem in the prior art that there is a lack of a vehicle body assembly that can meet the functions of single-row / half-row and double-row vehicle body assembly and has high equipment and site utilization.

[0036] Specifically, the split and combined positioning assembly 30 includes a guide component 31 respectively arranged on the first positioning assembly 10 and the second positioning assembly 20, a driving component 32 arranged on the first positioning assembly 10, a positioning rod 33 connected to the driving component 32, and a limiting shell 34 arranged on the second positioning assembly 20. The positioning rod 33 is adapted to the guide component 31. The guide component 31 of the second positioning assembly 20 is arranged in the limiting shell 34 and partially exposed from the limiting shell 34. The driving component 32 is used to drive the positioning rod 33 to approach or move away from the limiting shell 34. By providing the positioning rod 33 and the guide part, when it is necessary to assemble a double-row vehicle body, the second positioning assembly 20 is positioned at a predetermined position by the cooperation of the positioning rod 33 and the limiting shell 34 to cooperate with the first positioning assembly 10 to assemble the double-row vehicle body. When it is necessary to assemble a single-row or half-row vehicle body, the positioning rod 33 is reset so that the second positioning assembly 20 can be moved, and a position is vacated for assembling a single-row vehicle or a half-row vehicle through the first positioning assembly 10.

[0037] In addition, the guide component includes a concave fixing seat 311 and guide wheels 312 arranged on both sides of the top of the concave fixing seat 311. The positioning rod 33 is placed in the concave fixing seat 311 and guided by the two guide wheels 312. In a specific implementation, the positioning rod 33 is limited and guided by the guide wheels 312 arranged on both sides of the concave fixing seat, so that the positioning rod 33 can move along a preset direction, and the guide wheels 312 are arranged so that the guide wheels 312 and the positioning rod 33 slide and rub against each other, thereby reducing the loss of both and improving the service life.

[0038] Specifically, the vehicle body assembly further includes an assembly platform 50 , and the first positioning assembly 10 and the second positioning assembly 20 both include a bracket 11 and a fixture component 12 disposed on one side of the bracket 11 , and the bracket 11 is disposed on the assembly platform 50 .

[0039] In addition, a positioning pin component 13 and a positioning block 212 component 21 are respectively provided on opposite sides of the first positioning assembly 10 and the second positioning assembly 20. The positioning pin component 13 and the positioning block 212 component 21 are adapted to connect or separate the first positioning assembly 10 and the second positioning assembly 20. The bracket 11 of the second positioning assembly 20 is connected to the assembly platform 50 through the track assembly 60. A driving device 40 is provided on one side of the bracket 11 of the first positioning assembly 10. The driving device 40 is used to drive the track assembly 60 to make the second positioning assembly 20 approach or move away from the first positioning assembly 10. By providing the assembly platform 50 and the track assembly 60, when the splitting and combining positioning assembly 30 between the first positioning assembly 10 and the second positioning assembly 20 is separated, the second positioning assembly 20 is moved forward and backward under the left and right track assembly 60 through the driving device 40, so that the second positioning assembly 20 is separated from the first positioning assembly 10, providing space for the assembly of single-row or half-row vehicles.

[0040] Specifically, the positioning block 212 component 21 includes a connecting plate 211 connected to the bracket 11, a positioning block 212 arranged on the connecting plate 211, a positioning hole 213 is opened on the positioning block 212, and the positioning pin component 13 includes a cylinder 131 and an output rod 132 connected to the cylinder 131 and a protective shell 133 sleeved on the outside of the output rod 132, and the output rod 132 is adapted to the positioning hole 213. The cylinder 131 drives the output rod 132 to cooperate with the positioning hole 213 so that the first positioning components 10 are connected, fixed or separated with each other.

[0041] In addition, multiple positioning pin components 13 and positioning block 212 components 21 are all arranged on the side of the bracket 11. In addition, by adding multiple positioning pin components 13 and positioning block 212 components 21 to cooperate with each other, the positioning effect between the first positioning component 10 and the second positioning component 20 is further improved through multi-point positioning, ensuring that the assembly is in place, so as to ensure the assembly effect of different assembly modes of the overall body assembly.

[0042] Specifically, a single-row clamp component 14 is provided on the side of the bracket 11 of the first positioning assembly 10 close to the second positioning assembly 20. The single-row clamp component 14 is connected to the bracket 11 through a sliding connection component 15. The sliding connection component 15 is used to drive the single-row clamp component 14 to approach or move away from the second positioning assembly 20. In addition, a single-row clamp is also provided on the first positioning assembly 10. When half-row assembly is required, the single-row clamp is driven to move by the sliding connection component 15 to make room for half-row vehicle assembly. When single-row assembly is required, the single-row clamp is reset by the sliding connection component 15, so that the single-row clamp and the clamp component 12 fixed in position on the bracket 11 of the first positioning assembly 10 cooperate with each other to assemble single-row vehicles.

[0043] Furthermore, the sliding connection assembly 15 includes a slide rail frame 151 and a driving device 152 disposed on the bracket 11, and a slider adapted to the slide rail frame 151 is disposed on the single-row clamp component 14, and the driving device 152 is used to drive the single-row clamp component 14 to approach or move away from the second positioning assembly 20. Specifically, by arranging the slide rail frame 151 and the slider to cooperate, the single-row clamp can slide left and right on the bracket 11 of the first positioning assembly 10 when the driving device 152 is operated, thereby realizing the switching of different assembly modes of the vehicle body assembly.

[0044] In summary, the vehicle body assembly in the above-mentioned embodiment of the present invention is provided with a first positioning component 10 and a second positioning component 20, and the first positioning component 10 is a single-row / half-row positioning component, and the second positioning component 20 is a double-row positioning component, so that the vehicle body assembly can respectively realize the assembly functions of single-row, half-row and double-row vehicles, and then by providing a split positioning component 30 and a driving device 40, the second positioning component 20 and the first positioning component 10 can be connected or separated. When it is necessary to assemble a single-row or half-row vehicle, the second positioning component 20 is driven to move away from the first positioning component 10. When it is necessary to assemble a double-row vehicle, the second positioning component 20 is driven to move close to and connect to the first positioning component 10, and cooperate with the first positioning component 10 to realize the assembly of the double-row vehicle. Then, through such a setting, a set of fixtures can be reasonably used for the assembly of different types of vehicles, without the need to set up multiple sets of fixtures, thereby reducing costs. When switching modes, there is no need to repeatedly store or switch the fixtures, and only the position of the second positioning component 20 needs to be moved, which greatly reduces the space occupied by the equipment and improves space utilization. Therefore, the present invention solves the problem in the prior art that there is a lack of a vehicle body assembly that can meet the functions of single-row / half-row and double-row vehicle body assembly and has high equipment and site utilization.
