Description

Technical Field

[0001] This invention relates to the field of bus manufacturing technology, and in particular to a frame bonding tool for bus cabin doors and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, passenger vehicle doors include luggage compartment doors, side doors, and more than 20 doors of various sizes. Each door consists of a door panel and a frame structure. The frame structure and door panel need to be bonded together. After bonding, external force is required to provide clamping force and maintain it for a set time to form the door bonding line. The construction cycle for the door bonding line is 50 minutes. However, existing door bonding is usually a single-layer structure with a relatively simple structure. A clamping mechanism can provide clamping force to the door. Because the waiting time for the door bonding line is long, the entire door production cycle is long. If we want to improve efficiency, we would need multiple existing single-layer structures, which would occupy a large area, further increasing production costs. Moreover, it would increase the walking distance for placing the door, further increasing the labor intensity.

[0004] The existing single-layer structure rests directly on the ground, requiring workers to bend over multiple times to load and unload materials, which is labor-intensive. Moreover, for larger hatches, the limited space makes it difficult for workers to load or unload materials quickly. The existing single-layer structure can only provide clamping force and has poor versatility. When changing vehicle models, it is necessary to replace the bonding molds in batches. However, because the material loading position is low and the production line is long, the labor intensity is high and the mold replacement time is long. Since some factories have limited space and only single-layer bonding fixtures, frequent mold replacement is required, which reduces the service life and accuracy of the molds. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a frame bonding fixture for passenger car doors, which is beneficial to improving work efficiency and reducing the workload of workers.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A frame bonding fixture for a bus door includes a fixture frame with at least two accommodating spaces. Each accommodating space supports a clamping device to support the bus door to be bonded. The clamping device can provide clamping force to the bus door to be bonded. The clamping device is movable relative to the fixture frame to adapt to bus doors of different sizes and to make room for removing the bonded bus door. Each accommodating space can hold the bus door to be bonded. At least one accommodating space is provided with a push-pull bracket for holding the bus door to be bonded. The push-pull bracket can be pulled out relative to the fixture frame for easy loading or unloading.

[0007] As described above, a frame bonding fixture for a bus door includes a bottom template placed within the accommodating space. The bottom template supports the bus door to be bonded and cooperates with the pressing assembly to press the line at the bus door. The minimum height of the accommodating space is the sum of the maximum heights of the bottom template, the bus door to be bonded, and the pressing device. The minimum height of the partial accommodating space is the sum of the maximum heights of the push-pull bracket, the bottom mold, the passenger cabin door with adhesive, and the clamping device.

[0008] As described above, a frame bonding fixture for a passenger car door has two layers of accommodating space. The lower accommodating space contains a push-pull bracket, which is connected to the fixture frame via a guide rail structure. The guide rail structure includes a guide rail arranged along the width direction of the tooling frame. A slider is provided at the bottom of the push-pull bracket. The slider cooperates with the guide rail. An adjustable bearing assembly is provided at the outer end of the guide rail. The height of the adjustable bearing assembly is adjustable. The adjustable bearing assembly can contact the slider at the bottom of the push-pull bracket to limit the push-pull bracket.

[0009] As described above, a frame bonding fixture for a passenger car door includes an adjustable bearing assembly comprising two mounting plates supported by the fixture frame, a plurality of mounting holes provided along the height direction of the mounting plates, the bearing being supported by the mounting holes of the mounting plates, and the top surface of the bearing being higher than the upper surface of the guide rail.

[0010] As described above, a frame bonding fixture for a passenger car door includes a clamping device comprising a first support member arranged along the width of the fixture frame. Multiple clamping components are slidably mounted on the first support member. Each clamping component includes a second support member, which is perpendicularly connected to the first support member. A third support member is disposed below the second support member. A clamping mechanism is mounted on the second support member, and the telescopic end of the clamping mechanism passes through the second support member and connects to the third support member.

[0011] As described above, a frame bonding fixture for a passenger car door has a first linear bearing fixed to the lower surface of the first support member. The first linear bearing is arranged along the length of the first support member. A linear bearing slider passes through the first linear bearing and is fixed to the upper surface of the second support member. The linear bearing slider pushes the second support member relative to the first support member, thereby changing the position of the clamping mechanism. A guide shaft assembly is also provided between the second support member and the third support member. The guide shaft assembly includes an optical axis, the bottom of which is fixed to the surface of the third support member. The optical axis passes through the second support member and a second linear bearing, which is fixed to the upper surface of the second support member.

[0012] As described above, a frame bonding fixture for a passenger car door includes a frame consisting of a first frame, a second frame, a third frame, and a fourth frame arranged sequentially from bottom to top. The first frame is close to the ground, and the fourth frame is on top. Each frame is a hollow structure. Adjacent frames are spaced apart and connected by a vertical section. The first frame supports the second frame. A rear frame is provided on one side of the fixture frame and is connected to each frame. The second frame supports the push-pull bracket. The clamping device is located between the third and fourth frames and between the second and third frames.

[0013] As described above, in a frame bonding fixture for a passenger car door, the fourth and third frame layers of the fixture frame are provided with two L-shaped support seats on the side away from the rear frame, and the clamping device is supported by the L-shaped support seats and the rear frame of the fixture frame.

[0014] As described above, a frame bonding fixture for a passenger car door is provided, wherein the clamping mechanism is a linear drive cylinder, and a three-way connector or a four-way connector is supported by the second support member. A first pipeline is connected between the three-way connector and the four-way connector or two four-way connectors. The three-way connector and the four-way connector are respectively connected to the second pipeline. The second pipeline is connected to the linear drive cylinder, and the outermost four-way connector is connected to the air supply mechanism. The gas supply mechanism includes a gas pipe that is connected to an air compressor. A pressure regulating valve is installed between the gas pipe and the air compressor. The gas pipe has a branch pipe with a manual valve at the branch pipe. The branch pipe is connected to the outermost four-way connector.

[0015] Secondly, the present invention also provides a method for using a frame bonding fixture for a passenger car door, comprising the following: Place the bus door to be bonded into the receiving space, and support the bus door to be bonded from the bottom of the receiving space, or pull out the push-pull bracket, and support the bus door to be bonded from the push-pull bracket. After placement, push the push-pull bracket back into the tooling frame. The clamping component in the clamping device actuates to provide clamping force to the passenger car door to be bonded and holds it for a set time; After the set time, the clamping assembly is moved relative to the tooling frame to make room for removing the bonded bus door. The bonded bus door is then removed from the bottom of the receiving space or from the bottom of the push-pull bracket.

[0016] The beneficial effects of the present invention are as follows: 1) This invention provides a double-layer frame bonding fixture, including at least two layers of accommodating space. The accommodating space supports the clamping component, which in turn supports the bus door to be bonded. The clamping component provides clamping force to the bus door to be bonded, which facilitates the smooth bonding of the bus door. The at least two layers of accommodating space greatly improve the working capacity, make full use of space, and avoid the generation of invalid paths. The clamping component is movable relative to the fixture frame, thus making room for the bonded bus door and facilitating unloading (removing the bonded bus door). Moreover, the clamping component can be moved to reasonably arrange the position of the clamping component for bus doors of different sizes, making it suitable for bus doors of different sizes.

[0017] 2) In this invention, a bottom template is placed in the accommodating space to support the bus door and cooperate with the pressing component to press the line on the surface of the bus door. Because the push-pull bracket can be pulled out and the pressing component can be moved, it is convenient to quickly replace the bottom template. The height of the accommodating space is reasonably set to avoid the pressing component in the lower accommodating space from affecting the bus door to be bonded in the upper accommodating space.

[0018] 3) The tooling frame of this invention has two layers of storage space, making reasonable use of space. This allows for more workstations within a limited space, and the bottom templates of some workstations can be different, thus eliminating the need for frequent replacement of the bottom templates and ensuring their service life and accuracy. Moreover, the two layers of storage space facilitate loading and unloading of materials by workers. A push-pull bracket is set in the lower storage space, and the push-pull bracket is connected to the tooling frame through a guide rail structure, which facilitates the removal of the push-pull bracket. After the push-pull bracket is removed, it is convenient for workers to load and unload materials, especially for loading and unloading larger passenger car doors, effectively controlling labor intensity and improving work efficiency. An adjustable bearing assembly is set at the outer end of the guide rail to limit the maximum position of the push-pull bracket removal, ensuring safe operation.

[0019] 4) The clamping device in this invention has a reasonable structure and includes multiple clamping components. Each clamping component is movable relative to the first support member, which facilitates the adjustment of the distance between two adjacent clamping components so as to clamp passenger car doors of different sizes. It can also push the outer clamping components inward to make room for loading or unloading. Attached Figure Description

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, the existing bonding line has only a single-layer structure, which results in a large space occupation and is not conducive to loading and unloading. In order to solve the above technical problems, the present invention proposes a frame bonding fixture for passenger car doors.

[0032] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 5 As shown, a frame bonding fixture for a bus door includes a fixture frame 1. The fixture frame 1 includes at least two layers of receiving space. Each layer of receiving space supports a clamping device to support the bus door 7 to be bonded. The clamping device can provide clamping force to the bus door 7 to be bonded. The clamping device is movable relative to the fixture frame 1 to adapt to bus doors of different sizes and to make room for removing the bonded bus door. Each layer of receiving space can hold the bus door 7 to be bonded. At least one layer of receiving space is provided with a push-pull bracket 6 for holding the bus door 7 to be bonded. The push-pull bracket 6 can be pulled out relative to the fixture frame 1 for easy removal. After being pulled out, the push-pull bracket 6 provides more space and facilitates loading or unloading. For smaller bus doors 7, the push-pull bracket does not need to be pulled out, but for larger bus doors 7, the push-pull bracket 6 can be pulled out to facilitate loading or unloading, thus facilitating the loading and unloading of larger bus doors 7.

[0033] The tooling frame 1 has two layers of accommodating space. The lower accommodating space is equipped with a push-pull bracket 6 and a bottom template 8. The bottom template 8 is used to support the bus door 7 to be bonded and cooperates with the pressing component to press the line at the bus door 7. The minimum height of the accommodating space is the sum of the maximum height of the bottom template, the bus door 7 to be bonded, and the pressing device 4. The minimum height of part of the accommodating space is the sum of the maximum height of the push-pull bracket 6, the bottom template 8, the bus door 7 to be bonded, and the pressing device 4. The overall space is used in a reasonable way, so there are more workstations in a limited space. The bottom template 8 of some workstations can be different, so there is no need to frequently replace the bottom template 8, which ensures the service life and accuracy of the bottom template 8.

[0034] It is easy to understand that the tooling frame 1 is formed by welding multiple square tubes. The square tubes are made of high-strength steel to ensure the overall structural strength of the tooling frame. From bottom to top, the tooling frame 1 includes a first frame 11, a second frame 12, a third frame 13, and a fourth frame 15 arranged sequentially. The first frame 11 is close to the ground, and the fourth frame 15 is on the top. Each frame is a hollow structure. The adjacent frames are spaced apart and connected by a vertical section 14. The first frame 11 supports the second frame 12. Furthermore, the rear frame 16 on one side of the tooling frame 1 not only improves the overall strength but also limits the push-pull bracket 6. The rear frame 16 is connected to each layer of the frame. The second layer of the frame 12 supports the push-pull bracket 6, allowing the push-pull bracket 6 to be pulled out along the width of the tooling frame 1 relative to the tooling frame 1. The clamping device 4 is located between the third layer of the frame 13 and the fourth layer of the frame 15, and between the second layer of the frame 12 and the third layer of the frame 13. The clamping device 4 has two layers of frames, which can clamp the passenger car door separately.

[0035] In this embodiment, the push-pull bracket 6 moves along the tooling frame 1 via the guide rail assembly. Specifically, guide rails 2 are provided on the surface of the second layer frame of the tooling frame. There are two guide rails 2. The square tube in the middle of the second layer frame 12 is a perforated steel section. The guide rails 2 are fixed at the perforated square tube. The parallelism of the two square tubes needs to be controlled to ensure the parallelism of the guide rails 2, so as to ensure smooth operation after the push-pull bracket is fixed. An adjustable support bearing assembly 3 is pre-installed at the front end of the guide rail fixed to the steel section. The adjustable support bearing assembly 3 is fixed at the front end of the guide rail. The rear end of the guide rail is limited by the rear side frame.

[0036] Specifically, the adjustable support bearing assembly includes a mounting plate 31, which is fixed to the second frame 12. The two mounting plates 31 support the bearing 32. The central axis of the bearing 32 is perpendicular to the length direction of the guide rail 2. The top side of the bearing 32 is slightly higher than the upper surface of the guide rail to limit the slider 66 of the push-pull bracket 6.

[0037] refer to Figure 2As shown, the clamping device 4 includes a first support member 41, which is arranged along the width direction of the tooling frame 1. There are two first support members 41, which are spaced apart. The first support members 41 are supported by the tooling frame 1. Specifically, two L-shaped support seats 17 are arranged below the front side of the fourth frame 15 and the third frame 13 of the tooling frame. A transverse section 18 is arranged on the side of the tooling frame. The transverse section 18 and the L-shaped support seats 17 are located on the same plane to enhance the structural strength of the L-shaped support seats 17. The first support member 41 is supported by the L-shaped support seats 17 and the rear frame 16 of the tooling frame 1. Specifically, they can be welded together.

[0038] It should be noted that multiple sets of clamping components are slidably installed on the first support member 41. Each clamping component includes a second support member 47. The second support member 47 is located below the first support member 41. The second support member 47 is movable relative to the first support member 41. The second support member 47 is perpendicularly connected to the first support member 41. There are three second support members 47, with a distance between adjacent second support members 47. A third support member 45 is located below the second support member 47. A clamping mechanism 48 is fixed at the second support member 47. There can be multiple clamping mechanisms 48 to ensure uniform force. The clamping mechanism 48 is located between the two first support members 41. All clamping mechanisms 48 are existing linear drive cylinders. The telescopic end of the clamping mechanism passes through the second support member 47 and connects to the third support member 45, and is fastened with a nut. In this embodiment, a first linear bearing 42 is fixed to the lower surface of the first support member 41, and a linear bearing slider 43 is disposed through the first linear bearing 42. The linear bearing slider 43 is fixed to the upper surface of the second support member 47. By pushing the second support member 47 relative to the first support member 41, the position of the pressing mechanism 48 can be changed, thereby meeting the pressing requirements of different sized car doors. Moreover, by pushing the second support member 47 to make room, it is convenient to load or unload materials. In some examples, the linear bearing slider 43 is connected to a pushing mechanism such as a push motor. The pushing mechanism is fixed to the first support member 41, and the push-pull rod of the push motor drives the linear bearing slider, thereby pushing the second support member to move.

[0039] Specifically, the first linear bearing 42 is a long circle, the first linear bearing 42 is fixed at the first support member, and the linear bearing slider 43 can move along the first linear bearing 42.

[0040] A guide shaft assembly is also provided between the second support member 47 and the third support member 45, which is used to effectively guide the movement of the third support member 45.

[0041] In this embodiment, the first support member 41 is a square tube, the second support member 47 is a rectangular tube, and the third support member 45 is also a square tube.

[0042] Specifically, a second linear bearing 46 is fixed on the upper surface of the second support member 47. The second linear bearing 46 has a hollow structure. The guide shaft assembly includes an optical shaft 44, which passes through the second support member 47 and the second linear bearing 46. The optical shaft 44 ensures the perpendicularity of the guide shaft assembly. A support plate is provided at the bottom of the optical shaft 44. The support plate is fastened to the upper surface of the third support member 45 by M6*20 self-locking screws. The clamping mechanism is fixed to the second support member 47 by M6*20 socket head cap screws. refer to Figure 3 As shown, the push-pull bracket 6 includes a frame 61 welded from square tubes 62. The push-pull bracket 6 is hollowed out and has a connecting section inside. The connecting section connects to the frame 61 and includes a central connecting section 63 and two side connecting sections 64. A reinforcing section 65 is provided between the side connecting sections 64 and the side of the frame. The slider 66 is fixed to the bottom surface of the side connecting section 64. Two sliders 66 are provided on one side to ensure the stability of operation. The slider 66 is fixed to the lower surface of the side connecting section 64 with screws. To ensure the installation accuracy of the slider 66 and the guide rail on the tooling frame, the slider 66 is first installed on the guide rail 2 and then welded. After the push-pull bracket 6 is welded, the adjustable support bearing assembly 3 is installed so that the adjustable support bearing assembly 3 is in just contact with the push-pull bracket 6. The adjustable support bearing assembly 3 is tightened in place. To prevent loosening, additional welds can be added for reinforcement.

[0043] In addition, to drive the linear drive cylinder, a three-way connector 51 or a four-way connector 54 is supported by a second support member 47. A first pipeline 53 is connected between the three-way connector 51 and the four-way connector 54 or two four-way connectors 54. The first pipeline 53 is a spiral air pipe, which will not affect the movement of the pressing assembly. The three-way connector 51 and the four-way connector 54 are respectively connected to the second pipeline 52. The second pipeline 52 is connected to the linear drive cylinder. The outermost four-way connector is connected to the air supply mechanism 5.

[0044] refer to Figure 4 As shown, the air supply mechanism includes an air pipe 58, which is connected to an air compressor. A pressure regulating valve is installed between the air pipe and the air compressor. The air pipe is provided with a branch pipe 55, and a manual valve 56 is installed at the branch pipe. The branch pipe 55 is connected to the outermost four-way connector. The air compressor is placed on the ground, and the pressure regulating valve 57 and the manual valve 56 are installed on the side of the tooling frame 1.

[0045] The bonding fixture provided in this embodiment has a clamping component connected to the first support member 41 via a linear guide slider, which makes the inward and outward movement of the clamping component smoother and the operation easier. The second support member 47 and the third support member 45 are guided by a linear bearing and an optical axis, and the up and down movement is smooth. The upper and lower accommodating spaces have two layers. If the clamping device in one accommodating space fails, it will not affect the operation in the other accommodating spaces, which is convenient for maintenance and replacement. The fixture adopts a double-layer frame structure. The lower frame uses a guide rail and a push-pull bracket to facilitate the pulling out and replacement of the bonding template, thereby improving space utilization.

[0046] Example 2 This embodiment discloses a working method for a frame bonding fixture used in passenger car doors, referring to... Figure 6 and Figure 7 As shown, it includes the following: Place the bus door 7 to be bonded into the receiving space, and support the bus door 7 to be bonded from the bottom of the receiving space (place the bottom template 8), or pull out the bottom push-pull bracket 6, and support the bus door to be bonded from the push-pull bracket 6. After placement, push the push-pull bracket 6 back into the tooling frame 1. The clamping component in the clamping device 4 actuates to provide clamping force to the passenger car door 7 to be bonded and maintains it for a set time; After the set time, the clamping assembly is moved relative to the tooling frame to make room for removing the bonded bus door. The bonded bus door is then removed from the bottom of the receiving space or from the bottom of the push-pull bracket.

[0047] Multiple frame bonding fixtures for bus doors can be installed in the factory area, at least 20 units, which can bond bus doors of two different models at the same time without delaying the production cycle due to the replacement of the bottom template, thus reducing the impact on the accuracy of the bottom template.
