[0002] New energy controller is the core component in new energy automobile power system, needs to be connected and assembled with transmission assembly. Since new energy controller is equipped with cooling water channel, therefore, the sealing structure with O-ring is used between the butt joint of transmission. This butt joint process not only involves the mechanical connection between controller and transmission, but also involves the sealing performance of cooling water channel, when butt joint assembly, it needs to ensure higher positioning accuracy, because the deviation in butt joint process can cause O-ring to be bumped or extruded uneven in installation process, and then cause air-tightness leakage problem. Leakage not only reduces the efficiency of cooling system, but also can cause damage to internal electronic components of controller, affects the service life and safety of new energy controller.

[0003] In actual assembly process, new energy controller is mostly dependent on guide column auxiliary positioning, and the butt joint with transmission assembly is completed by artificial hoisting. Although guide column provides guidance in installation direction to some extent, due to the operation error of artificial hoisting itself, such as unevenness of hoisting plane, shaking in hoisting process, etc., the precision of installation plane is difficult to be effectively guaranteed, so that O-ring at cooling water channel butt joint is easy to be impacted by external force, deformation or damage is generated, and the sealing performance of system is reduced.

[0004] In addition, new energy controller and its supporting parts (such as tray, motor shell, etc.) in production and processing process, due to the limitation of manufacturing process, material performance and quality control factors, its dimensional accuracy and consistency often exist certain fluctuation range. These small differences are amplified when controller and transmission assembly are connected, further intensify positioning difficulty, increase the risk of O-ring bumping and leakage.

[0037] The principles and features of the present application are described below in conjunction with examples, and the examples are only used to explain the present application and are not intended to limit the scope of the present application.

[0038] As Figures 1-6As shown, a floating positioning tool for vehicle component assembly includes a U-shaped bracket 110 and a floating support mechanism 120, the U-shaped bracket 110 includes a left bracket beam 111, a right bracket beam 112 and a rear bracket beam 113 connected between the left bracket beam 111 and the right bracket beam 112, and the left bracket beam 111 and the right bracket beam 112 are provided with exit guide rails 114, two groups of floating support mechanisms 120 are installed on the exit guide rails 114 of the left bracket beam 111 and the right bracket beam 112 respectively, each group of floating support mechanisms 120 includes an exit cylinder 121, an upper floating plate 122, a floating assembly 123 and a lower positioning seat 124, the lower positioning seat 124 is slidingly installed on the corresponding exit guide rail 114, the exit cylinder 121 is installed on the U-shaped bracket 110, the extension shaft of the exit cylinder 121 is connected with the lower positioning seat 124, and the exit cylinder 121 can drive the tool to move on the exit guide rail 114, the floating assembly 123 is installed between the lower positioning seat 124 and the upper floating plate 122, and the floating assembly 123 can support the upper floating plate 122 to realize floating on a plane.

[0039] The upper floating plate 122 and the lower positioning seat 124 of the floating positioning tool are connected through the floating assembly 123, the floating assembly 123 can stably support the upper floating plate 122 and allow it to freely float on a plane, that is, the upper floating plate 122 is not fixed at a position, but can move or adjust the position within a plane range.

[0040] More specifically, the floating assembly 123 includes a hollow outer shell 1231, which is fixed above the lower positioning seat 124. It also includes a support seat 1232, an upper flat bearing 1235, and a lower flat bearing 1236 disposed within the outer shell 1231. The support seat 1232 includes a frustum 1233 and a cylindrical step 1234 disposed on the top surface of the frustum 1233. The diameter of the cylindrical step 1234 is smaller than that of the frustum 1233. The lower flat bearing 1236 is installed at the bottom of the frustum 1233. The upper flat bearing 1235 is sleeved on the cylindrical step 1234. The cylindrical step 1234 passes through the outer shell 1231 and is fixedly connected to the upper floating plate 122. The floating assembly 123 enables the upper floating plate 122 and the lower positioning seat 124 to be connected by a planar bearing. The frustum 1233 of the support seat 1232 is enclosed between the upper planar bearing 1235 and the lower planar bearing 1236. When the upper floating plate 122 is installed on the cylindrical step 1234 of the support seat 1232, if it is subjected to external force, the support seat 1232 can drive the upper floating plate 122 to move or adjust its position in the plane, so that the upper floating plate 122 can cope with the resistance during the assembly process and reduce the hard collision between the controller and the transmission during assembly.

[0041] In this embodiment, a clamping cylinder 170 is also provided on the floating support mechanism 120 on the left side. Depending on the actual assembly requirements and equipment characteristics, the clamping cylinder 170 can be provided on the floating support mechanism 120 on the right side, or on both sides of the floating support mechanism 120. Therefore, the specific location of the clamping cylinder 170 can be selected and adjusted according to the specific assembly situation. The clamping cylinder 170 is mounted on the upper floating plate 122, and the end of the telescopic shaft of the clamping cylinder 170 is connected to a pressure head 172 via a connecting plate 171. The clamping cylinder 170 can drive the pressure head 172 to move up and down. When the clamping cylinder 170 drives the pressure head 172 to move downward, it can clamp the equipment to be assembled and fix it firmly on the upper floating plate 122. Since the clamping cylinder 170 is directly mounted on the upper floating plate 122, it can move synchronously with the movement of the upper floating plate 122 in the plane, so that the equipment to be assembled can move freely within a preset range in the plane with the upper floating plate 122 during the assembly process.

First, since the diameter of the limiting hole 140 is greater than that of the limiting column 130, the limiting column 130 does not strictly limit the movement of the upper floating plate 122, that is, the equipment to be assembled can freely move in any direction in the plane of the upper floating plate 122 during the assembly process, and has sufficient movement allowance. Secondly, although the limiting column 130 does not limit the movement of the upper floating plate 122, it can effectively prevent the upper floating plate 122 from accidentally falling off or deviating during movement. After the limiting column 130 is inserted into the limiting hole 140, a stable supporting relationship is formed between them, so that the upper floating plate 122 can be kept within the predetermined movement range even under external force, thereby avoiding assembly errors or equipment damage caused by excessive movement.

[0043] The upper floating plate 122 is further provided with one or more limiting blocks 150, which are used to limit the equipment to be assembled on the upper floating plate 122 and prevent the equipment to be assembled from moving on the upper floating plate 122. The size and shape of the limiting block 150 are matched with the equipment to be assembled, and the precise positioning of the equipment can be realized by adjusting the position and number of the limiting block 150, so as to meet the needs of different assembly scenes.

[0044] The rear bracket beam 113 is further provided with a sensor 160, which is used to detect whether the equipment to be assembled is placed in place. The sensor 160 makes the assembly process more intelligent and automated, reduces the need for manual intervention, and improves the accuracy and efficiency of the assembly.

[0045] The method for the floating positioning tool to assemble the new energy controller and the transmission in the utility model is as follows:

[0046] Firstly, the exit cylinder 121 is started to make the extension shaft extend, and the two groups of floating support mechanisms 120 are pushed to move close to each other along the respective exit guide rails 114 until they reach the specified docking position.

[0047] Then, the new energy controller is placed on the upper floating plate 122. Subsequently, the compression cylinder 170 is started, and the driving pressure head 172 of the compression cylinder 170 starts to move downward until the new energy controller is clamped and stably positioned on the upper floating plate 122.

[0048] Below the floating positioning tool, a conveying line is arranged, and the transmission is placed below the new energy controller through the conveying line and is ensured to have the docking port facing upward so as to be docked and assembled with the new energy controller.

[0049] As Figure 7 shown, in actual assembly, the rear bracket beam 113 is connected with the lifting driving mechanism 400, the lifting driving mechanism 400 can drive the floating positioning tool to move up and down, adjust the height and position of the floating positioning tool, and can realize the up and down butt joint assembly between devices. When the lifting driving mechanism 400 is started, the lifting driving mechanism 400 will drive the floating positioning tool and the new energy controller located on the floating positioning tool to move downward as a whole, and butt joint assembly with the transmission. In the assembly process, if external or internal resistance is encountered, the new energy controller can move and adjust the position within a certain range in any direction in the plane along the upper floating plate 122, prevent the controller from colliding with the transmission, can ensure that the O-ring and other vulnerable components are not subjected to unnecessary impact and damage during assembly, thereby improving the assembly quality and efficiency;

[0050] Finally, when the butt joint assembly is completed, the exit cylinder 121 is started again, the retractable shaft is retracted, the two groups of floating support mechanisms 120 will move away from each other along the respective exit guide rails 114, and the butt joint position is exited, and the next assembly operation is prepared.

[0051] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
