Description

Technical Field

[0001] This utility model relates to a floating assembly equipment for vehicle components, belonging to the technical field of equipment assembly lines. Background Technology

[0002] The new energy vehicle controller is a core component of the new energy vehicle's powertrain system and needs to be assembled with the transmission assembly. Because the controller contains cooling water channels, the connection with the transmission requires a sealing structure with an O-ring guide flange. This assembly process involves not only the mechanical connection between the controller and the transmission but also the sealing performance of the cooling water channels. High positioning accuracy is crucial during assembly, as deviations during the process can cause the O-ring guide flange to be subjected to impacts or uneven pressure during installation, leading to airtightness leaks. Leaks not only reduce the efficiency of the cooling system but can also damage the controller's internal electronic components, affecting its lifespan and safety.

[0003] In actual assembly, new energy controllers often rely on guide columns for positioning and are manually hoisted to connect with the transmission assembly. Although guide columns provide some guidance in the installation direction, the inherent operational errors of manual hoisting, such as unevenness of the hoisting surface and shaking during the hoisting process, make it difficult to effectively guarantee the accuracy of the installation surface. This can lead to the O-ring guide flange at the cooling water channel connection being easily subjected to external impacts, resulting in deformation or damage and reducing the system's sealing performance.

[0004] Furthermore, during the production and processing of new energy controllers and their supporting components (such as trays and motor housings), due to limitations in manufacturing processes, material properties, and quality control, the dimensional accuracy and consistency often exhibit a certain range of fluctuation. These minute differences are amplified when the controller is docked with the transmission assembly, further exacerbating positioning difficulties and increasing the risk of impact and leakage to the O-ring guide flange. Utility Model Content

[0005] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: A floating assembly equipment for vehicle components includes a support frame, a floating positioning fixture, a lifting drive cylinder, and a lifting and positioning mechanism. The floating positioning fixture includes a U-shaped bracket and a floating support mechanism. The U-shaped bracket includes a left bracket beam, a right bracket beam, and a rear bracket beam. A lifting guide rail is provided on the support frame. The bracket is slidably mounted on the lifting guide rail via the rear bracket beam. The lifting drive cylinder can drive the floating positioning fixture to move along the lifting guide rail. Two sets of floating support mechanisms are respectively mounted on the left bracket beam and the right bracket beam. The lifting and positioning mechanism is mounted below the floating positioning fixture.

[0007] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This utility model constructs an integrated vehicle component assembly line through a support frame, floating positioning fixture, lifting drive cylinder, and lifting positioning mechanism. The coordinated work of the floating positioning fixture and the lifting positioning mechanism enables two vehicle components (such as a new energy controller and a transmission) to be precisely docked on the same assembly line. The floating positioning fixture includes a U-shaped bracket and a floating support mechanism. The U-shaped bracket ensures the support and positioning of the vehicle component to be assembled above, and the lifting positioning mechanism carries and lifts the vehicle component to be assembled below. In conjunction with the floating positioning fixture, the accuracy and efficiency of assembly are improved.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the floating support mechanism includes an upper floating plate, a floating component, and a lower positioning seat. The lower positioning seat is mounted on the bracket, and the floating component is mounted between the lower positioning seat and the upper floating plate. The floating component is capable of supporting the upper floating plate to float on a plane.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the upper floating plate and the lower positioning seat of this utility model are connected by a floating component. The floating component can stably support the upper floating plate and allow it to float freely on the plane. That is, the upper floating plate is not fixed in a certain position, but can move and adjust its position within the plane. In practical applications, when using the tooling of this utility model for docking and assembling equipment, the equipment to be assembled is first clamped and positioned on the upper floating plate. Subsequently, during the assembly process, if external or internal resistance is encountered, the equipment to be assembled can move freely in any direction within the plane along with the upper floating plate. By allowing the parts to float freely on the plane, this utility model can ensure that components such as O-rings are not subjected to unnecessary impacts and damage during assembly, thereby significantly improving the quality and efficiency of assembly.

[0011] Furthermore, the floating assembly includes a hollow outer shell, a support base, an upper planar bearing, and a lower planar bearing. The outer shell is fixed above the lower positioning base. The support base, the upper planar bearing, and the lower planar bearing are disposed inside the outer shell. The support base includes a frustum base and a cylindrical step disposed on the top surface of the frustum base. The diameter of the cylindrical step is smaller than that of the frustum base. The lower planar bearing is installed at the bottom of the frustum base. The upper planar bearing is sleeved on the cylindrical step. The cylindrical step passes through the outer shell and is fixedly connected to the upper floating plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the floating assembly realizes the load-bearing connection between the upper floating plate and the lower positioning seat by the planar bearing. The frustum seat of the support seat is wrapped between the upper planar bearing and the lower planar bearing. When the upper floating plate is installed on the cylindrical step of the support seat, it can move or adjust its position within a certain range when subjected to external force, so that the upper floating plate can cope with the resistance during the assembly process and reduce the hard collision between the controller and the transmission during assembly.

[0013] Furthermore, both the left and right support beams are equipped with exit guide rails. The two sets of floating support mechanisms are slidably mounted on the exit guide rails of the left and right support beams respectively via their respective lower positioning seats. The system also includes two sets of exit cylinders, which are respectively mounted on the left and right support beams, and the telescopic shafts of the two sets of exit cylinders are respectively connected to the lower positioning seats of the two sets of floating support mechanisms.

[0014] The beneficial effect of adopting the above-mentioned further solution is that after the vehicle parts are assembled, the exit cylinder can be activated to drive the floating support mechanism to exit along the exit guide rail in a timely manner, thereby quickly releasing the support of the vehicle parts and facilitating the subsequent processes or the removal of the vehicle parts.

[0015] Furthermore, the floating support mechanism on the left bracket beam and / or the right bracket beam is also provided with a pressing cylinder, the pressing cylinder is installed on the upper floating plate, and the end of the telescopic shaft of the pressing cylinder is provided with a pressure head.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the clamping cylinder drives the pressure head to move downward, it can clamp and stably position the equipment to be assembled on the upper floating plate. Since the clamping cylinder is directly mounted on the upper floating plate, it can move synchronously with the movement of the upper floating plate 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 during the assembly process.

[0017] Furthermore, the floating support mechanism also includes a limiting post, which is installed on the lower positioning seat. The upper floating plate is provided with a limiting hole, and the limiting post is inserted into the limiting hole. The diameter of the limiting hole is larger than the diameter of the limiting post.

[0018] The advantages of adopting the above-mentioned further solution are as follows: First, since the diameter of the limiting hole is larger than that of the limiting post, the limiting post does not strictly restrict the movement of the upper floating plate. That is, the equipment to be assembled can move freely in any direction in the plane along with the upper floating plate during the assembly process, with a certain amount of movement allowance. Second, although the limiting post does not restrict the movement of the upper floating plate, it can effectively prevent the upper floating plate from accidentally falling off or shifting during movement. When the limiting post is inserted into the limiting hole, a stable support relationship is formed between them. Even under the action of external force, the upper floating plate can be kept within the predetermined range of movement, avoiding assembly errors or equipment damage caused by excessive movement.

[0019] Furthermore, the lifting and positioning mechanism includes a base, an upper lifting plate, a lower lifting plate, a main lifting cylinder, and an auxiliary lifting cylinder. The cylinder body of the main lifting cylinder is mounted on the base. The upper lifting plate is located above the lower lifting plate. The upper lifting plate and the lower lifting plate are connected by a guide assembly. The cylinder body of the auxiliary lifting cylinder is mounted on the lower lifting plate. The telescopic shaft of the auxiliary lifting cylinder is connected to the upper lifting plate. The auxiliary lifting cylinder can drive the upper lifting plate to move up and down relative to the lower lifting plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the main lifting cylinder and the auxiliary lifting cylinder, a step-by-step lifting and docking operation is achieved. First, the main lifting cylinder drives the upper lifting plate to rise a certain distance, roughly aligning the vehicle component to be assembled above (such as the new energy controller) with the vehicle component to be assembled below (such as the transmission), ensuring initial vertical proximity. Then, the auxiliary lifting cylinder is activated to achieve complete docking of the upper and lower vehicle components. This step-by-step lifting method not only improves the accuracy of docking but also reduces potential component damage or assembly deviations caused by direct, forceful lifting.

[0021] Furthermore, the guide assembly includes an inner guide flange and an outer guide flange, the outer guide flange being slidably sleeved outside the inner guide flange, the inner guide flange being connected to the lower lifting plate, and the outer guide flange being connected to the upper lifting plate.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it ensures the stable and precise up-and-down movement of the upper lifting plate on the lower lifting plate, and improves the stability and alignment accuracy of the lifting positioning mechanism.

[0023] Furthermore, the upper lifting plate is also provided with one or more positioning pins.

[0024] Furthermore, it also includes a conveyor line, which is disposed between the floating positioning fixture and the lifting positioning mechanism. The conveyor line is provided with a tray, and the tray is provided with a pin hole that mates with the positioning pin.

[0025] The advantages of adopting the above-mentioned further solution are as follows: First, the conveyor line is set between the floating positioning fixture and the lifting positioning mechanism. The pallet has pin holes that mate with the positioning pins, allowing the vehicle components to be assembled below (such as the transmission) to be easily transferred via the conveyor line to the area below the vehicle components to be assembled above (such as the new energy controller). The use of the conveyor line improves the automation level of the assembly line and reduces the time and labor intensity of manual handling. Second, when the lifting positioning mechanism is activated, the upper lifting plate can lift the pallet along with the vehicle components to be assembled below it. During the lifting process, the positioning pins engage with the pin holes on the pallet, effectively preventing the pallet from moving during the lifting process and ensuring precise docking of the upper and lower vehicle components.

They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0045] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0046] like Figure 1 and Figure 2 As shown, the technical solution provided by this utility model is as follows: A floating assembly equipment for vehicle components includes a support frame 200, the support frame 200 including a base 201 and a mounting column 202 installed on one side of the base 201, and also includes a floating positioning fixture 100, a lifting drive cylinder 400 and a lifting positioning mechanism 300. The floating positioning fixture 100 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. 13 is connected between the left bracket beam 111 and the right bracket beam 112. The column 202 is provided with a lifting guide rail. The bracket is slidably installed on the lifting guide rail through the rear bracket beam 113. The lifting drive cylinder 400 can drive the floating positioning fixture 100 to move along the lifting guide rail. Two sets of floating support mechanisms 120 are respectively installed on the left bracket beam 111 and the right bracket beam 112. The lifting positioning mechanism 300 is installed on the base 201 and located below the floating positioning fixture 100.

[0047] like Figures 3-8 As shown, the floating support mechanism 120 includes an upper floating plate 122, a floating component 123, and a lower positioning seat 124. The lower positioning seat 124 is mounted on the bracket, and the floating component 123 is mounted between the lower positioning seat 124 and the upper floating plate 122. The floating component 123 can support the upper floating plate 122 to float on the plane.

[0048] In practical applications, when using the tooling of this invention for docking and assembling equipment, the equipment to be assembled is first clamped and positioned on the upper floating plate 122. Subsequently, during the assembly process, if external or internal resistance is encountered, the equipment to be assembled can move freely in any direction within the plane along with the upper floating plate 122, allowing for fine-tuning of the assembly position.

[0049] The floating assembly 123 includes a hollow outer shell 1231, a support base 1232, an upper planar bearing 1235, and a lower planar bearing 1236. The outer shell 1231 is fixed above the lower positioning base 124. The support base 1232, the upper planar bearing 1235, and the lower planar bearing 1236 are disposed inside the outer shell 1231. The support base 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 planar bearing 1236 is installed at the bottom of the frustum 1233. The upper planar 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 wrapped 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, it can move or adjust its position within a certain range when subjected to external force, 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.

[0050] Both the left support beam 111 and the right support beam 112 are equipped with exit guide rails 114. The two sets of floating support mechanisms 120 are slidably mounted on the exit guide rails 114 of the left support beam 111 and the right support beam 112 via their respective lower positioning seats 124. The system also includes two sets of exit cylinders 121, which are respectively mounted on the left support beam 111 and the right support beam 112, and the telescopic shafts of the two sets of exit cylinders 121 are respectively connected to the lower positioning seats 124 of the two sets of floating support mechanisms 120. After the vehicle component is assembled, the exit cylinders 121 can be activated, causing their telescopic shafts to drive the floating support mechanisms 120 to exit along the exit guide rails 114 in a timely manner, thereby quickly releasing the support for the vehicle component and facilitating subsequent processes or the removal of the vehicle component.

[0051] 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 part to be assembled and fix it 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.

[0052] The floating support mechanism 120 also includes a limiting post 130, which is mounted on the lower positioning seat 124. The upper floating plate 122 has a limiting hole 140, and the limiting post 130 is inserted into the limiting hole 140. The diameter of the limiting hole 140 is larger than the diameter of the limiting post 130. First, since the diameter of the limiting hole 140 is larger than that of the limiting post 130, the limiting post 130 does not strictly restrict the movement of the upper floating plate 122. That is, the equipment to be assembled can move freely in any direction in the plane with the upper floating plate 122 during the assembly process, with a margin for movement. Second, although the limiting post 130 does not restrict the movement of the upper floating plate 122, it can effectively prevent the upper floating plate 122 from accidentally falling off or shifting during the movement. When the limiting post 130 is inserted into the limiting hole 140, a stable support relationship is formed between them. Even under the action of external force, the upper floating plate 122 can remain within the predetermined range of movement, avoiding assembly errors or equipment damage caused by excessive movement.

[0053] The floating support mechanism 120 also includes a limiting post 130, which is mounted on the lower positioning seat 124. The upper floating plate 122 has a limiting hole 140, and the limiting post 130 is inserted into the limiting hole 140. The diameter of the limiting hole 140 is larger than the diameter of the limiting post 130. First, since the diameter of the limiting hole 140 is larger than that of the limiting post 130, the limiting post 130 does not strictly restrict the movement of the upper floating plate 122. That is, the equipment to be assembled can move freely in any direction in the plane with the upper floating plate 122 during the assembly process, with sufficient movement margin. Second, although the limiting post 130 does not restrict the movement of the upper floating plate 122, it can effectively prevent the upper floating plate 122 from accidentally falling off or shifting during the movement. When the limiting post 130 is inserted into the limiting hole 140, a stable support relationship is formed between them. Even under the action of external force, the upper floating plate 122 can remain within the predetermined range of movement, avoiding assembly errors or equipment damage caused by excessive movement.

[0054] The upper floating plate 122 is also provided with one or more limiting blocks 150. The limiting blocks 150 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 blocks 150 are adapted to the equipment to be assembled. By adjusting the position and number of the limiting blocks 150, the equipment can be accurately positioned, thereby meeting the needs of different assembly scenarios.

[0055] The rear support beam 113 is also equipped with a sensor 160, which is used to detect whether the equipment to be assembled is placed in the correct position. The sensor 160 makes the assembly process more intelligent and automated, reduces the need for manual intervention, and improves the accuracy and efficiency of assembly.

[0056] like Figures 7-11As shown, the lifting and positioning mechanism 300 includes a base 310, an upper lifting plate 320, a lower lifting plate 330, a main lifting cylinder 340, and an auxiliary lifting cylinder 350. The base 310 is mounted on the support frame 200. The cylinder body of the main lifting cylinder 340 is mounted on the base 310. The upper lifting plate 320 is located above the lower lifting plate 330. The upper lifting plate 320 and the lower lifting plate 330 are connected by a guide assembly 360. The cylinder body of the auxiliary lifting cylinder 350 is mounted on the lower lifting plate 330. The telescopic shaft of the auxiliary lifting cylinder 350 is connected to the upper lifting plate 320. The auxiliary lifting cylinder 350 can drive the upper lifting plate 320 to move up and down relative to the lower lifting plate 330. By using the main lifting cylinder 340 and the auxiliary lifting cylinder 350 in conjunction, a step-by-step lifting and docking operation is achieved. First, the main lifting cylinder 340 drives the upper lifting plate 320 to rise a certain distance, roughly aligning the vehicle component to be assembled above (such as the new energy controller) with the vehicle component to be assembled below (such as the transmission), ensuring initial vertical proximity. Then, the auxiliary lifting cylinder 350 is activated to achieve complete docking of the upper and lower vehicle components. This step-by-step lifting method not only improves docking accuracy but also reduces potential component damage or assembly deviations caused by direct, forceful lifting.

[0057] The guide assembly 360 includes an inner guide flange 361 and an outer guide flange 362. The outer guide flange 362 is slidably sleeved outside the inner guide flange 361. The inner guide flange 361 is connected to the lower lifting plate 330, and the outer guide flange 362 is connected to the upper lifting plate 320. This ensures stable and precise vertical movement of the upper lifting plate 320 on the lower lifting plate 330, improving the stability and alignment accuracy of the lifting and positioning mechanism 300.

[0058] The upper lifting plate 320 is also provided with one or more positioning pins 370. The floating assembly equipment also includes a conveyor line 500, which is located between the floating positioning fixture 100 and the lifting positioning mechanism 300. The conveyor line 500 is provided with a tray 501, which has pin holes that mate with the positioning pins 370. First, the conveyor line 500 is located between the floating positioning fixture 100 and the lifting positioning mechanism 300. The tray 501 has pin holes that mate with the positioning pins 370, so that the vehicle parts to be assembled below (such as the transmission) can be easily transferred to the area below the vehicle parts to be assembled above (such as the new energy controller) via the conveyor line 500. The use of the conveyor line 500 improves the automation level of the assembly line and reduces the time and labor intensity of manual handling. Second, when the lifting positioning mechanism 300 is activated, the upper lifting plate 320 can lift the tray 501 and the vehicle parts to be assembled below it upwards. During the lifting process, the positioning pin 370 engages with the pin hole on the pallet 501, effectively preventing the pallet 501 from moving during the lifting process and ensuring precise docking of the vehicle components.

[0059] The method for assembling the new energy controller and the transmission using the floating positioning fixture 100 of this utility model is as follows:

[0060] First, activate the withdrawal cylinder 121 to extend its telescopic shaft, which pushes the two sets of floating support mechanisms 120 closer to each other along their respective withdrawal guide rails 114 until they reach the designated docking position.

[0061] Next, the new energy controller is placed on the upper floating plate 122. Then, the clamping cylinder 170 is activated, and the driving head 172 of the clamping cylinder 170 begins to move downward until the new energy controller is clamped and stably positioned on the upper floating plate 122.

[0062] Then, the transmission is placed on tray 501 and transported to the bottom of the new energy controller via conveyor line 500, ensuring that the transmission interface faces upwards for docking and assembly with the new energy controller.

[0063] Once ready, the lifting drive cylinder 400 is activated, which will drive the floating positioning fixture 100 and the new energy controller located on the floating positioning fixture 100 to move downward as a whole. At the same time, the main lifting cylinder 340 is activated, which first drives the upper lifting plate 320 to rise a certain distance, so that the new energy controller and the transmission are roughly aligned, ensuring that the two are initially close in the vertical direction. Then, the auxiliary lifting cylinder 350 is activated to achieve complete docking between the upper vehicle components and the lower vehicle components.

[0064] During the assembly process, if external or internal resistance is encountered, the new energy controller can move and adjust its position in any direction within a certain range along with the upper floating plate 122, preventing the controller from colliding hard with the transmission. This ensures that vulnerable parts such as O-rings are protected from unnecessary impact and damage during assembly, thereby improving assembly quality and efficiency.

[0065] Finally, after the docking assembly is completed, the exit cylinder 121 is activated again to retract its telescopic shaft. The two sets of floating support mechanisms 120 will move away from each other along their respective exit guide rails 114 and exit the docking position. The telescopic shafts of the main lifting cylinder 340 and the auxiliary lifting cylinder 350 retract, and the pallet 501 falls back onto the conveyor line 500. The assembled equipment is then transported to the next work station via the conveyor line 500.

[0066] This utility model constructs an integrated vehicle component assembly line through a support frame 200, a floating positioning fixture 100, a lifting drive cylinder 400, and a lifting and positioning mechanism 300. The coordinated work of the floating positioning fixture 100 and the lifting and positioning mechanism 300 enables two vehicle components (such as a new energy controller and a transmission) to be precisely connected on the same assembly line. The floating positioning fixture 100 includes a U-shaped bracket 110 and a floating support mechanism 120. The U-shaped bracket 110 ensures the support and positioning of the vehicle component to be assembled above, while the lifting and positioning mechanism 300 carries and lifts the vehicle component to be assembled below. In cooperation with the floating positioning fixture 100, the accuracy and efficiency of assembly are improved.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
