Description

Technical Field

[0001] This invention belongs to the field of automotive clamping technology, and specifically relates to a device for disassembling automotive instrument crossbeams. Background Technology

[0002] The instrument panel assembly line is one of the more important lines in the final assembly workshop. The instrument panel assembly line is used for the assembly of components such as instrument beams, instrument wiring harnesses, steering columns, and instrument panels into complete assemblies. These components are then picked up and installed in the front compartment of the vehicle by a assisted robotic arm. Among these, the design of the instrument panel assembly trolley is a key issue to ensure stable positioning, convenient operation, and compatibility during the instrument beam assembly.

[0003] However, the current instrument beam assembly trolley uses a fixed port structure to connect with the end of the instrument beam. When the length or inner diameter of the instrument beam is different, the assembly trolley cannot be adapted. This is especially true for left-hand drive and right-hand drive export models, as the inner diameter and structure of the instrument beams are different. As a result, the clamp end of the assembly trolley must be modified on-site, which increases or decreases time and cost and increases the difficulty of operation. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a vehicle instrument crossbeam sub-assembly trolley device, comprising: a support frame, a bearing assembly, a support frame, connecting shafts, a crossbeam lap joint, a pin, and a bearing reducer. The support frame is symmetrically mounted on the left and right sides, and the bearing assembly and bearing reducer are respectively mounted on the support frames on the left and right sides. Connecting shafts are rotatably mounted on the bearing assembly and bearing reducer, and the connecting shafts on both sides are coaxially arranged.

[0005] Both sides of the connecting shaft have slidingly installed pins on their facing end sidewalls for docking with the inner wall of the instrument beam, and both sides have fixedly installed beam lap joints for lapping with the outer wall of the instrument beam.

[0006] Furthermore, the side wall of the connecting shaft is provided with a protrusion extending along the axis of the connecting shaft. The pin includes a pin block, a sliding plate, and a sliding block. The sliding block has a groove that slides and connects with the protrusion. The pin block and the sliding block are respectively installed on both sides of the sliding plate.

[0007] Furthermore, the upper end of the sliding plate is provided with a protrusion, on which a positioning pin is installed that penetrates the side wall of the protrusion. Several positioning slots are provided on the side wall of the connecting shaft, and the several positioning slots are arranged at equal intervals along the axis of the connecting shaft to form an insertion with the positioning pin.

[0008] Furthermore, the sliding block includes two locking parts and a sliding part. The two locking parts are arranged vertically and symmetrically mounted on the side wall of the sliding plate. The sliding part is mounted between the two locking parts and is clamped and fixed by the two locking parts. The side wall of the sliding part is provided with a sliding groove that forms a sliding connection with the connecting shaft.

[0009] Furthermore, the insert has a semi-circular cylindrical cross-section. The sidewall of the insert includes a flat surface and a semi-circular curved surface. The curved surface at one end of the insert abuts against the sliding plate. The outer wall of the other end of the sliding plate is provided with a stop block, and the stop block also has a semi-circular cross-section.

[0010] Furthermore, the crossbeam lap joint includes a mounting plate, a first support block, a second support block, and a plug-in part;

[0011] The mounting plate has a plug-in part, and the end of the connecting shaft is provided with a plug-in groove. The plug-in part is inserted into the plug-in groove and fixedly connected by bolts.

[0012] The first support block and the second support block are both installed on the side wall of the mounting plate and are located on the same side as the pin. The first support block has a crossbeam mounting groove corresponding to the pin, and the side wall of the first support block with the crossbeam mounting groove adopts a sloping structure.

[0013] The second support block is located between the first support block and the pin. The second support block includes a first component and a second component arranged vertically, and a gap is reserved between the first component and the second component to avoid the pin.

[0014] Furthermore, the crossbeam lap joint also includes a telescopic limit pin, which is installed on both sides of the mounting plate along with the first support block. Both the first support block and the mounting plate are provided with through holes arranged coaxially with the telescopic limit pin.

[0015] Furthermore, the second component of the second support block is provided with a limiting slot or limiting groove for accommodating the radial bracket at the end of the instrument beam.

[0016] Furthermore, it also includes a steady-state connecting rod, which has a U-shaped structure. The two ends of the steady-state connecting rod are connected to the side walls of the connecting shafts on both sides, respectively. The ends of the steady-state connecting rod are arranged perpendicular to the side walls of the connecting shafts, and the axis of the steady-state connecting rod is coplanar with the axis of the connecting shafts on both sides.

[0017] Furthermore, it also includes an air conditioning support accessory, which is detachably installed in the middle of the steady link and used to connect to the air conditioning connection end on the instrument crossbeam.

[0018] The present invention relates to an automotive instrument panel crossbeam assembly trolley device. Based on the use of crossbeam lap joints to overlap both ends of the instrument panel crossbeam, adjustable pins on both sides are inserted into the inner walls of both ends of the crossbeam, respectively. This allows the side walls of the crossbeam to abut against the lap joints, thus fixing the lap joints. This meets the usage requirements of instrument panel crossbeams of different lengths. Furthermore, the method of overlapping first and then fixing allows the assembly of the instrument panel crossbeam to meet the needs of individual operation, protecting the instrument panel crossbeam ends while reducing labor intensity, saving personnel, improving production line programming efficiency, and reducing manufacturing costs.

[0019] The insert has a semi-circular cylindrical cross-section with added stops to improve the fit between the insert end and the inner wall of the instrument beam end of different specifications, meeting the operational requirements of various specifications; and through the first support block and the second support block, the crossbeam connecting piece is compatible with the two instrument beam structures of existing models and new models, and ensures the normal operation of the insert component, meeting the requirement of stable placement of the instrument beam.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a trolley device for disassembling automotive instrument crossbeams. Figure 1 A schematic diagram of the automotive instrument crossbeam disassembly trolley device according to an embodiment of the present invention is shown. Figure 1 In the process, the automotive instrument crossbeam sub-assembly trolley device includes a load-bearing frame 1, a bearing assembly 2, a support frame 3, a connecting shaft 4, a crossbeam lap joint 5, a pin 6, and a bearing reducer 9;

[0033] refer to Figure 2 and Figure 3 The diagram shows a partial schematic of the right and left support frames in an embodiment of the present invention. Support frames 3 are symmetrically installed on the support frame 1. Bearing assemblies 2 and bearing reducers 9 are respectively installed on the left and right support frames 3. Connecting shafts 4 are rotatably installed on the bearing assemblies 2 and bearing reducers 9 respectively, and the connecting shafts 4 on both sides are arranged coaxially.

[0034] Both sides of the connecting shaft 4 have slidably installed pins 6 for docking with the inner wall of the instrument beam on their facing end sidewalls, and both sides have fixedly installed beam lap joints 5 for lapping with the outer wall of the instrument beam.

[0035] In the sub-assembly trolley device of this application, based on the use of crossbeam overlap parts 5 to overlap the two ends of the instrument crossbeam, the adjustable pins 6 on both sides are respectively inserted into the inner walls of the two ends of the instrument crossbeam, so that the crossbeam overlap parts 5 and the pins 6 clamp the inner and outer walls of the instrument crossbeam, thereby fixing the crossbeam overlap parts 5 to meet the usage requirements of instrument crossbeams of different lengths. Moreover, the method of overlapping first and then limiting makes the assembly operation of the instrument crossbeam meet the needs of single-person operation, protects the instrument crossbeam port, reduces the labor intensity of personnel, saves personnel, improves the programming efficiency of production line personnel, and reduces manufacturing costs.

[0036] For details, please refer to Figure 5 and Figure 2 The side wall of the connecting shaft 4 is provided with a protrusion 41 extending along the axis of the connecting shaft 4. The pin 6 includes a pin 61, a sliding plate 62, and a sliding block 63. The sliding block 63 is provided with a groove that slides and connects with the protrusion 41. The pin 61 and the sliding block 63 are respectively installed on both sides of the sliding plate 62, so that the pin 6 can move left and right on the protrusion 41 along the axis of the connecting shaft 4, thereby changing the distance between the two pins 61 to meet the requirement that the axial length of the instrument beam of different models is not uniform.

[0037] The sliding plate 62 has a protrusion 64 at its upper end, on which a positioning pin 65 is installed, penetrating the side wall of the protrusion 64. The side wall of the connecting shaft 4 has several positioning slots 42, which are evenly spaced along the axis of the connecting shaft 4 to form an insertion with the positioning pin 65. Depending on the length of the instrument beam, after adjusting the spacing of the pins 6 on both sides to fit the corresponding instrument beam, the positioning pin 65 can be directly inserted into the corresponding positioning slot 42 to fix the position of the pin 6. Figure 2 In the example shown, the positioning pin 65 can be connected to the positioning slot 42 by a thread; a spring can also be provided between the positioning pin 65 and the side wall of the protrusion 64, and the spring is set to be in a natural state when the positioning pin 65 is inserted into the positioning slot 42, and in a stretched state when the positioning pin 65 is not inserted into the positioning slot 42.

[0038] Among them, reference Figure 5 In the example shown, the sliding block 63 includes two locking parts and a sliding part. The two locking parts are arranged vertically and symmetrically mounted on the side wall of the sliding plate 62. The sliding part is mounted between the two locking parts and is clamped and fixed by the two locking parts. The side wall of the sliding part is provided with a sliding groove that forms a sliding connection with the connecting shaft 4, which facilitates the later maintenance and replacement of the sliding part.

[0039] Among them, reference Figure 2 and Figure 5The insert 61 has a semi-circular cylindrical cross-section. The sidewall of the insert 61 includes a flat surface and a curved surface with a semi-circular structure. One end of the curved surface of the insert 61 abuts against the sliding plate 62. The other end of the sliding plate 62 has a stop 66 on its outer wall. The stop 66 also has a semi-circular cross-section, which makes the end of the insert 61 form two semi-circular cylindrical joints with different diameters. The end of the insert 61 corresponds to the end size of the instrument beam of the right-hand drive vehicle, and the stop 66 corresponds to the end size of the instrument beam of the left-hand drive vehicle in China. This structure can solve the problem of inconsistent end diameters of the instrument beam between domestic and international models, and can axially clamp and fix the left and right sides of the instrument beam. The semi-circular sidewall increases the tightness of the compression fit between the end of the insert 61 and the inner wall of the instrument beam.

[0040] This application does not imply any limitation on the number and size of the stops 66 on the insert 61. Stops 66 arranged in ascending order of size can be designed directly according to requirements to accommodate the inner diameter of other instrument beams of different specifications.

(Reference) Figure 4 In the example shown, the insertion part 55 has two sets of mounting holes arranged in an array, for a total of four mounting holes, and the insertion groove 43 at the end of the connecting shaft 4 has a set of vertically arranged corresponding mounting holes. The mounting holes on the insertion groove 43 can be selected from the mounting holes on the insertion part 55 for installation as needed, thereby realizing the initial adjustment of the distance between the crossbeam lap joint 5 and the connecting shaft 4.

[0043] The first support block 52 and the second support block 53 are both installed on the side wall of the mounting plate 51 and are located on the same side as the pin 6. The first support block 52 has a crossbeam mounting groove corresponding to the pin 6, and the side wall of the first support block 52 with the crossbeam mounting groove adopts a sloping structure.

[0045] Correspondingly, the crossbeam lap joint 5 also includes a telescopic limit pin 54. The telescopic limit pin 54 and the first support block 52 are respectively installed on both sides of the mounting plate 51, and the first support block 52 and the mounting plate 51 are both provided with through holes arranged coaxially with the telescopic limit pin 54.

[0046] The instrument beam is fixed by using a crossbeam mounting groove and a beveled structure to overlap with the end of the new instrument beam, and by inserting a telescopic limit pin 54 into the side hole at the end of the instrument beam.

[0047] Correspondingly, in Figure 4 In the example shown, the second component of the second support block 53 has a limiting groove for accommodating the radial bracket at the end of the instrument beam; and in Figure 6 In the example shown, the second component of the second support block 53 has a limiting slot for accommodating the radial bracket at the end of the instrument beam. For the existing instrument beam, the first and second components overlap at the end of the instrument beam, and the end of the instrument beam has a built-in limiting pin that can be directly inserted into the limiting slot or limiting groove to fix the instrument beam.

[0048] The first support block 52 and the second support block 53 are arranged in a left-right manner, so that the crossbeam connecting piece 5 is compatible with the two instrument crossbeam structures of existing models and new models, and ensures the normal operation of the pin piece 6, meeting the requirement of stable placement of the instrument crossbeam.

[0049] refer to Figure 1 As shown in the example, the device of this application also includes a steady-state connecting rod 7, which has a U-shaped structure. The two ends of the steady-state connecting rod 7 are respectively connected to the side walls of the connecting shaft rods 4 on both sides. The ends of the steady-state connecting rod 7 are arranged perpendicularly to the side walls of the connecting shaft rods 4, and the axis of the steady-state connecting rod 7 is coplanar with the axis of the connecting shaft rods 4 on both sides, so that the connecting shaft rods 4 on both sides and the steady-state connecting rod 7 form a whole, directly strengthening the strength of the overall frame and ensuring the structural stability of the instrument beam trolley when it rotates.

[0050] It also includes an air conditioning support accessory 8, which is detachably installed in the middle of the steady link 7 and is used to connect to the air conditioning connection end on the instrument crossbeam. By using the steady link 7 as a fixed platform to fix the air conditioning support accessory 8, the support and limit of the air conditioning connection end on the instrument crossbeam can be achieved.

[0051] The air conditioning auxiliary support base 8 is designed with limit holes. Different HVAC support accessories are designed according to the support structure of the HVAC (heating, ventilation and air conditioning) assembly of different models. Before assembling the HVAC assembly, the corresponding HVAC support accessory is placed on the air conditioning support accessory 8 according to the vehicle assembly list. The HVAC support accessory is designed with limit pins that are inserted into the limit holes of the air conditioning support accessory 8 to achieve quick switching and improve on-site operation efficiency.

[0052] The automotive instrument panel crossbeam assembly trolley device described in this application can be made of materials such as aluminum alloy, nylon pads, and angle steel. (Reference) Figure 7In actual use, when assembling the instrument beam, first place the instrument beam on the assembly trolley. First, overlap the left end face of the instrument beam with the beam overlap piece 5 mounted on the bearing assembly 2, and slide the left pin 6 into the inner diameter of the left shaft tube of the instrument beam. Then, move the left pin 6 on the right connecting shaft 4 to limit the inner diameter of the right shaft tube of the instrument beam. The lower part of the corresponding HVAC (Heating, Ventilation and Air Conditioning) assembly is supported on the air conditioning support bracket 8. No manual support is required; an electric screwdriver can be used to directly fix the assembly to the instrument beam. When assembling other poorly visible locations, the bearing assembly 2 can be rotated under the action of the bearing reducer 9 to adjust the overall angle of the instrument beam to meet the assembly space requirements of different positions.

[0053] This device is easy and simple to operate, compatible with various instrument beam structures, reducing the amount of modification required when introducing new models, shortening the time for equipment modification, and saving modification costs. At the same time, it improves air conditioning assembly operations by assisting in the positioning of HVAC assemblies, reducing labor intensity, saving labor costs, improving the programming efficiency of production line personnel, reducing manufacturing costs, and is easy to operate with reasonable ergonomics.
