Description

Technical Field

[0001] The invention belongs to the technical field of processing chassis components of recreational vehicles, and in particular relates to a production and processing device for chassis components of a lightweight trailer recreational vehicle. Background Art

[0002] As an important part of the RV, the chassis of the trailer RV bears the weight of the body and interior furniture, and is directly related to driving safety, stability and riding comfort. The chassis components mainly include key parts such as the traction system, frame, suspension system, braking system and tires. With the continuous development of new energy technologies, some RVs are driven by new energy. They are generally driven by plug-in hybrid and extended-range hybrid. Both require the arrangement of the engine or range extender system and the battery pack system on the chassis assembly, so the installation of the battery pack is often involved in the production and processing of the chassis assembly.

[0003] At present, the chassis of RVs driven by new energy sources is often equipped with a battery pack system in the middle of the chassis in order to lower the center of gravity of the RV and facilitate the layout of the battery system. The middle part of the chassis of RVs driven by new energy sources is generally provided with an installation frame for installing the battery pack. The current installation method of the battery pack is to place the chassis assembly on a fixed table, and to transport the battery pack manually with a robot, and to place the battery pack in a suitable position for installation. The whole installation process is relatively complicated, and it is impossible to achieve rapid positioning and installation of the battery pack.

[0004] At the same time, when installing the battery pack, the current installation method is that after the battery pack is in place, it is necessary to use a lifting device to lift the battery pack to the installation position, and then operate the external automatic screw feeding machine to position it to the bolt installation position. During the bolt tightening process, the operation of the entire tightening process is extremely cumbersome and urgently needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a production and processing device for a lightweight trailer caravan chassis assembly to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lightweight trailer caravan chassis component production and processing device, comprising two front and rear symmetrical transverse guide rails, the interiors of the two transverse guide rails are movably connected with transverse guide blocks, a frame is fixedly connected between the two transverse guide blocks, a bottom plate is fixedly installed on the top of the frame, a battery tray is provided above the bottom plate, a linkage shaft is movably installed on one side of the top of the bottom plate, the linkage shaft rotates relative to the bottom plate, a limit shaft is fixedly installed on the top of the linkage shaft, one end of the battery tray is movably connected with the limit shaft, the battery tray moves up and down relative to the limit shaft, extension plates are installed on the left and right sides of the middle of the bottom plate, auxiliary locking components are movably connected inside the extension plates, the top of the auxiliary locking components are symmetrically installed on the left and right sides of the bottom end of the battery tray, auxiliary support seats are installed on the front and back sides of the middle of the bottom end of the battery tray, when the battery tray is located directly above the bottom plate, the bottom end of the auxiliary support seat contacts the top of the bottom plate, and a laser rangefinder is installed on the relatively far side of the two auxiliary locking components.

[0007] Before use, the device can be installed on an external guide rail, and the displacement of the device can be controlled by the external guide rail so that it can be moved to the bottom of the RV chassis assembly to be processed. At the same time, the specifications of the battery tray need to be adjusted according to the specifications of the battery pack to be installed to ensure that the size of the battery tray corresponds to the battery pack. At the same time, an operator is required to stand on one side of the device to load the battery pack to complete the preparation before chassis assembly processing.

[0008] As a further technical solution of the present invention, an extension seat is installed at one end of the two transverse guide rails, a main motor is installed on the inner side of the extension seat, and a threaded seat is installed at one end of the two transverse guide blocks that are relatively far away.

[0009] As a further technical solution of the present invention, the inner side surface of the threaded seat is threadedly connected with a screw rod, the screw rod is movably connected to the transverse guide rail, the screw rod rotates relative to the transverse guide rail, and one end of the main motor output shaft is connected to the screw rod.

[0010] When the battery pack needs to be installed and positioned, the laser rangefinder at one end of the two auxiliary locking assemblies can be used to measure the left and right ends of the battery mounting frame inside the RV chassis assembly. When the left and right distance measurement data are inconsistent, if the value on the left is smaller than the value on the right, the main motor can be started and the screw rod can be driven to rotate. At this time, the threaded seat is displaced relative to the transverse guide rail under the guidance of the transverse guide block and the transverse guide rail, and drives the top bottom plate to displace relative to each other, that is, drives the bottom plate and the top battery tray to displace to the right, until the data of the laser rangefinders at both ends are exactly the same, the adjustment process is completed, and the battery tray can be displaced to the bottom of the battery mounting frame.

[0011] By installing a laser rangefinder on one side of the auxiliary locking assembly and utilizing the left and right displacement of the frame and the difference in data measured on both sides, the position of the battery tray can be dynamically adjusted so that the battery tray can be quickly adjusted to the middle position of the battery mounting frame. The entire process can be completed quickly without the need for repeated manual adjustments. Rapid adaptive adjustments can be made to the battery installation of chassis assemblies of different vehicle models, thereby improving the versatility of the device and the installation efficiency.

[0012] As a further technical solution of the present invention, one side of the bottom end of the base plate is fixedly connected to a mounting seat located below the linkage shaft, the inner side of the mounting seat is fixedly connected to a servo motor, and the top end of the servo motor output shaft is connected to the bottom end of the linkage shaft.

[0013] As a further technical solution of the present invention, a main cylinder is symmetrically installed on one side of the top of the base plate away from the linkage shaft, and when the battery tray is located directly above the base plate, the output end of the main cylinder contacts the bottom end of the battery tray.

[0014] When the battery tray is adjusted to the middle position of the battery installation frame, the servo motor can be turned on to drive the linkage shaft to rotate and drive the limit shaft at the top to rotate synchronously. When the limit shaft rotates, the battery tray can be driven to rotate synchronously. When the battery tray rotates to 180 degrees, the battery tray can be located on one side of the bottom plate, which corresponds to the loading station. The operator then places the battery inside the battery tray. After the placement is completed, the linkage shaft continues to rotate 180 degrees until the battery tray is completely located above the bottom plate. At this time, the battery is just located below the battery installation frame, completing the positioning process before installation.

[0015] After positioning is completed, the main cylinder can be opened and controlled to extend. At this time, the main cylinder at the top can push the battery tray upward. At this time, the battery tray moves upward relative to the limit axis until the battery at the top of the battery tray rises to the inside of the installation frame, completing the installation process.

[0016] By utilizing the rotatable battery tray in conjunction with the extension effect of the main cylinder, the battery tray can realize the battery loading, positioning and installation process, so that only one operator is needed to control the battery loading, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, and there is no need for traditional devices to require manual cooperation with robots and the need for repeated positioning. The installation efficiency of the battery pack can be significantly improved, and production costs can be reduced.

[0017] As a further technical solution of the present invention, the auxiliary locking assembly includes a longitudinal guide rail, and vacuum suction cups are installed on the left and right sides of the bottom end of the longitudinal guide rail. The two longitudinal guide rails are located on the left and right sides of the bottom end of the battery tray. When the battery tray is located directly above the bottom plate, the bottom end of the vacuum suction cup and the top end of the extension plate are adsorbed on each other.

[0018] As a further technical solution of the present invention, the interior of the longitudinal guide rail is movably connected with a longitudinal guide block, and the longitudinal guide block is displaced left and right relative to the longitudinal guide rail. An extension shaft is installed at one end of the two longitudinal guide blocks that is relatively far away from each other, and the end of the extension shaft that is far away from the longitudinal guide block passes through one end of the longitudinal guide rail and is fixedly connected to a mounting frame.

[0019] As a further technical solution of the present invention, the two mounting brackets are located on the left and right sides of the battery tray, the top ends of the mounting brackets are fixedly connected with automatic screw-tightening machines, and the top ends of the longitudinal guide blocks are fixedly installed with first fixing seats.

[0020] As a further technical solution of the present invention, one end of the first fixed seat away from the longitudinal guide block is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and the top end of the second fixed seat is connected to the bottom end of the battery tray.

[0021] When the battery pack is installed upward, that is, the battery pack is directly below the battery installation frame, the vacuum suction cup can be turned on to control the mutual adsorption between the vacuum suction cup and the extension plate to complete the fixation. When the battery tray moves upward under the action of the main cylinder, the two connecting rods at the bottom end will deflect accordingly, that is, deflect toward the middle, thereby driving the longitudinal guide block at the bottom end to move, that is, the longitudinal guide block moves relative to the longitudinal guide rail, and the two longitudinal guide blocks move closer to each other, and drive the two mounting frames and the automatic screw feeding machine to move closer to each other. When the battery pack rises to the inside of the installation frame, the automatic screw feeding machine just moves to the bolt installation hole position, and the locking process of the battery pack can be automatically completed by controlling the automatic screw feeding machine.

[0022] By utilizing the upward installation process of the battery pack and cooperating with the function of the auxiliary locking assembly, when the battery tray rises, the two automatic screw-feeding machines can be relatively close to each other, so that they can be quickly positioned to the bolt installation holes. The entire process can be completed automatically without manual control, which avoids the problem of traditional devices requiring the battery pack to be lifted and then using the automatic screw-feeding machine to position and tighten the bolts. This simplifies the operating steps and improves the overall production and processing efficiency.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention utilizes a rotatable battery tray in conjunction with the extension effect of the main cylinder, so that the battery tray can realize the loading, positioning and installation process of the battery, so that only one operator is needed to control the loading of the battery, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, and there is no need for manual cooperation with a robot and repeated positioning in traditional devices. The installation efficiency of the battery pack can be significantly improved and the production cost can be reduced.

[0025] 2. The present invention utilizes the upward installation process of the battery pack and cooperates with the function of the auxiliary locking assembly. When the battery tray rises, the two automatic screw-feeding machines can be relatively close to each other, so that they can be quickly positioned to the bolt installation holes. The whole process can be completed automatically without manual control. The problem of traditional devices requiring the battery pack to be lifted and then using the automatic screw-feeding machine to position and lock the bolts can be avoided. The operating steps are simplified and the overall production and processing efficiency is improved.

[0026] 3. The present invention utilizes a rotatable battery tray in conjunction with the extension effect of the main cylinder so that the battery tray can realize the loading, positioning and installation process of the battery, so that only one operator is needed to control the loading of the battery, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly without the need for manual cooperation with a robot and the need for repeated positioning as in traditional devices. The installation efficiency of the battery pack can be significantly improved and the production cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, in the embodiment of the present invention, a lightweight trailer caravan chassis component production and processing device includes two front-to-rear symmetrical transverse guide rails 1, the interiors of the two transverse guide rails 1 are movably connected with transverse guide blocks 5, a frame 7 is fixedly connected between the two transverse guide blocks 5, a bottom plate 8 is fixedly installed on the top of the frame 7, a battery tray 15 is provided above the bottom plate 8, a linkage shaft 11 is movably installed on one side of the top of the bottom plate 8, the linkage shaft 11 rotates relative to the bottom plate 8, a limit shaft 12 is fixedly installed on the top of the linkage shaft 11, and one end of the battery tray 15 is movably connected to the limit shaft 12 The battery tray 15 is clamped and moves up and down relative to the limit axis 12. Extension plates 14 are installed on both sides of the left and right sides of the middle of the bottom plate 8. Auxiliary locking components 17 are movably clamped inside the extension plates 14. The top ends of the auxiliary locking components 17 are symmetrically installed on the left and right sides of the bottom end of the battery tray 15. Auxiliary support seats 16 are installed on the front and back sides of the middle of the bottom end of the battery tray 15. When the battery tray 15 is located directly above the bottom plate 8, the bottom end of the auxiliary support seat 16 contacts with the top end of the bottom plate 8, and a laser rangefinder is installed on the side where the two auxiliary locking components 17 are relatively far away.

[0038] Before use, the device can be installed on an external guide rail, and the displacement of the device can be controlled by the external guide rail so that it can be moved to the bottom of the RV chassis assembly to be processed. At the same time, the specifications of the battery tray 15 need to be adjusted accordingly according to the specifications of the battery pack to be installed to ensure that the battery tray 15 corresponds to the size of the battery pack. At the same time, an operator is required to stand on one side of the device to load the battery pack to complete the preparation before chassis assembly processing.

[0039] like Figure 1 and Figure 2 as well as Figure 3 and Figure 4 As shown, an extension seat 2 is installed at one end of the two transverse guide rails 1, and a main motor 3 is installed on the inner side of the extension seat 2. A threaded seat 6 is installed at the relatively far end of the two transverse guide blocks 5, and a screw rod 4 is threadedly connected to the inner side of the threaded seat 6. The screw rod 4 is movably connected to the transverse guide rail 1, and the screw rod 4 rotates relative to the transverse guide rail 1. One end of the output shaft of the main motor 3 is connected to the screw rod 4.

[0040] When the battery pack needs to be installed and positioned, the laser rangefinder at one end of the two auxiliary locking assemblies 17 can be used to measure the distance of the left and right ends of the battery mounting frame inside the RV chassis assembly. When the left and right distance measurement data are inconsistent, if the value on the left is smaller than the value on the right, the main motor 3 can be started and the screw rod 4 can be driven to rotate. At this time, the threaded seat 6 is displaced relative to the transverse guide rail 1 under the guidance of the transverse guide block 5 and the transverse guide rail 1, and drives the bottom plate 8 at the top to move relative to each other, that is, drives the bottom plate 8 and the top battery tray 15 to move toward the right, until the data of the laser rangefinders at both ends are exactly the same, and the adjustment process is completed. At this time, the battery tray 15 can be displaced to the bottom of the battery mounting frame.

[0041] By installing a laser rangefinder on one side of the auxiliary locking assembly 17 and utilizing the left and right displacement of the frame 7 and the difference in the data measured on both sides, the position of the battery tray 15 can be dynamically adjusted so that the battery tray 15 can be quickly adjusted to the middle position of the battery mounting frame. The entire process can be completed quickly without the need for repeated manual adjustments. Rapid adaptive adjustments can be made to the battery installation of chassis assemblies of different vehicle models, thereby improving the versatility of the device and the installation efficiency.

[0042] like Figure 1 and Figure 3 and Figure 5 as well as Figure 6 As shown, one side of the bottom end of the base plate 8 is fixedly connected to a mounting base 9 located below the linkage shaft 11, the inner side of the mounting base 9 is fixedly connected to a servo motor 10, the top end of the output shaft of the servo motor 10 is connected to the bottom end of the linkage shaft 11, and a master cylinder 13 is symmetrically installed on one side of the top end of the base plate 8 away from the linkage shaft 11. When the battery tray 15 is located directly above the base plate 8, the output end of the master cylinder 13 is in contact with the bottom end of the battery tray 15.

[0043] Embodiment: When the battery tray 15 is adjusted to the middle position of the battery installation frame, the servo motor 10 can be turned on to drive the linkage shaft 11 to rotate, and drive the limit shaft 12 at the top to rotate synchronously. When the limit shaft 12 rotates, the battery tray 15 can be driven to rotate synchronously. When the battery tray 15 rotates to 180 degrees, the battery tray 15 can be located on one side of the bottom plate 8, which corresponds to the loading station. The operator then places the battery inside the battery tray 15. After the placement is completed, the linkage shaft 11 continues to rotate 180 degrees until the battery tray 15 is completely located above the bottom plate 8. At this time, the battery is just located below the battery installation frame, completing the positioning process before installation.

[0044] After positioning is completed, the main cylinder 13 can be opened and controlled to extend. At this time, the main cylinder 13 at the top can push the battery tray 15 to move upward. At this time, the battery tray 15 moves upward relative to the limit shaft 12 until the battery at the top of the battery tray 15 rises to the inside of the installation frame, completing the installation process.

[0045] By utilizing the rotatable battery tray 15 in conjunction with the extension effect of the main cylinder 13, the battery tray 15 can realize the battery loading, positioning and installation process, so that only one operator is needed to control the battery loading, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, and there is no need for traditional devices to manually cooperate with robots and require repeated positioning. The installation efficiency of the battery pack can be significantly improved and production costs can be reduced.

[0046] like Figure 2 and Figure 7 as well as Figure 8As shown, the auxiliary locking assembly 17 includes a longitudinal guide rail 171, and vacuum suction cups 172 are installed on the left and right sides of the bottom end of the longitudinal guide rail 171. The two longitudinal guide rails 171 are located on the left and right sides of the bottom end of the battery tray 15. When the battery tray 15 is located directly above the bottom plate 8, the bottom end of the vacuum suction cup 172 and the top end of the extension plate 14 are adsorbed on each other, and the interior of the longitudinal guide rail 171 is movably connected with a longitudinal guide block 173, and the longitudinal guide block 173 is displaced left and right relative to the longitudinal guide rail 171. An extension shaft 177 is installed on the relatively far ends of the two longitudinal guide blocks 173, and the extension shaft 177 is away from the longitudinal guide block One end of 173 passes through one end of the longitudinal guide rail 171 and is fixedly connected to a mounting bracket 178. The two mounting brackets 178 are located on the left and right sides of the battery tray 15. The top of the mounting bracket 178 is fixedly connected to an automatic screw machine 179. The top of the longitudinal guide block 173 is fixedly installed with a first fixed seat 174. The end of the first fixed seat 174 away from the longitudinal guide block 173 is movably connected to a connecting rod 176 through a rotating shaft. The end of the connecting rod 176 away from the first fixed seat 174 is movably connected to a second fixed seat 175 through a rotating shaft. The top of the second fixed seat 175 is connected to the bottom end of the battery tray 15.

[0047] Embodiment: When the battery pack is installed upward, that is, the battery pack is directly below the battery installation frame, the vacuum suction cup 172 can be turned on to control the mutual adsorption between the vacuum suction cup 172 and the extension plate 14 to complete the fixation. When the battery tray 15 moves upward under the action of the main cylinder 13, the two connecting rods 176 at the bottom are deflected accordingly, that is, they are deflected toward the middle, thereby driving the longitudinal guide block 173 at the bottom to move, that is, the longitudinal guide block 173 is displaced relative to the longitudinal guide rail 171, and the two longitudinal guide blocks 173 are relatively close to each other, and drive the two mounting frames 178 and the automatic screw feeding machine 179 to move relatively close. When the battery pack rises to the inside of the installation frame, the automatic screw feeding machine 179 is just moved to the bolt installation hole position, and the locking process of the battery pack can be automatically completed by controlling the automatic screw feeding machine 179.

[0048] By utilizing the upward installation process of the battery pack and cooperating with the function of the auxiliary locking assembly 17, when the battery tray 15 rises, the two automatic screw-feeding machines 179 can be relatively close to each other, so that they can be quickly positioned to the bolt installation holes. The entire process can be completed automatically without manual control, which can avoid the problem of traditional devices requiring the battery pack to be lifted and then using the automatic screw-feeding machine 179 to position and tighten the bolts. This simplifies the operating steps and improves the overall production and processing efficiency.

[0049] Working principle and usage process:

[0050] Before use, the device can be installed on the external guide rail, and the displacement of the device can be controlled by the external guide rail so that it can be moved to the bottom of the RV chassis assembly to be processed. At the same time, the specifications of the battery tray 15 need to be adjusted accordingly according to the specifications of the battery pack to be installed to ensure that the battery tray 15 corresponds to the size of the battery pack. At the same time, an operator is required to stand on one side of the device for the battery pack loading operation to complete the preparation before the chassis assembly processing;

[0051] When it is necessary to install and position the battery pack, the laser rangefinders at one end of the two auxiliary locking assemblies 17 can be used to measure the distance of the left and right ends of the battery installation frame inside the RV chassis assembly. When the left and right distance measurement data are inconsistent, if the value on the left is smaller than the value on the right, the main motor 3 can be started and the screw rod 4 can be driven to rotate. At this time, the threaded seat 6 is displaced relative to the transverse guide rail 1 under the guidance of the transverse guide block 5 and the transverse guide rail 1, and drives the bottom plate 8 at the top to move relative to each other, that is, drives the bottom plate 8 and the top battery tray 15 to move toward the right, until the data of the laser rangefinders at both ends are exactly the same, the adjustment process can be completed, and the battery tray 15 can be displaced to the bottom of the battery installation frame.

[0052] When the battery tray 15 is adjusted to the middle position of the battery installation frame, the servo motor 10 can be turned on to drive the linkage shaft 11 to rotate, and drive the limit shaft 12 at the top to rotate synchronously. When the limit shaft 12 rotates, the battery tray 15 can be driven to rotate synchronously. When the battery tray 15 rotates to 180 degrees, the battery tray 15 can be located on one side of the bottom plate 8, which corresponds to the loading station. The operator then places the battery inside the battery tray 15. After the placement is completed, the linkage shaft 11 continues to rotate 180 degrees until the battery tray 15 is completely located above the bottom plate 8. At this time, the battery is just located below the battery installation frame, completing the positioning process before installation.

[0053] After positioning is completed, the main cylinder 13 can be turned on and controlled to extend, and the main cylinder 13 at the top can push the battery tray 15 to move upward. At this time, the battery tray 15 moves upward relative to the limit shaft 12 until the battery at the top of the battery tray 15 rises to the inside of the installation frame, completing the installation process;

[0054] When the battery pack is installed upward, that is, the battery pack is directly below the battery installation frame, the vacuum suction cup 172 can be turned on to control the mutual adsorption between the vacuum suction cup 172 and the extension plate 14 to complete the fixation. When the battery tray 15 moves upward under the action of the main cylinder 13, the two connecting rods 176 at the bottom are deflected accordingly, that is, deflected toward the middle, thereby driving the longitudinal guide block 173 at the bottom to move, that is, the longitudinal guide block 173 is displaced relative to the longitudinal guide rail 171, and the two longitudinal guide blocks 173 are relatively close to each other, and drive the two mounting frames 178 and the automatic screw feeding machine 179 to move relatively close. When the battery pack rises to the inside of the installation frame, the automatic screw feeding machine 179 is just moved to the bolt installation hole position, and the locking process of the battery pack can be automatically completed by controlling the automatic screw feeding machine 179.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
