Description

Technical Field

[0001] This application relates to the field of leaf spring mounting equipment, and more specifically, to an auxiliary positioning device for mounting leaf springs in vehicle production. Background Technology

[0002] Automotive leaf springs are the most traditional elastic elements in automotive suspension systems, offering advantages such as high reliability, simple structure, short manufacturing process, low cost, and significantly simplified structure.

[0003] Currently, one of the production processes in vehicle manufacturing is installing leaf springs onto the axle. During installation, it's crucial to ensure the leaf springs are perpendicular to the axle, that the two leaf springs on either side of the axle are parallel, and that the two leaf springs are equidistant from the axle's edge. Therefore, auxiliary installation and positioning devices are often used, such as rulers. Installers typically measure dimensions using a ruler to achieve proper positioning, requiring multiple measurements and adjustments, which increases installation time and reduces efficiency. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an auxiliary positioning device for installing leaf springs in vehicle production, which can achieve centering and fixing of the axle. By clamping and positioning the leaf springs, the leaf springs are transported to both sides of the axle, ensuring the relative perpendicularity between the leaf springs and the axle, as well as the parallelism between the two leaf springs. It also ensures that the edge distances of the two leaf springs to the axle are the same, thereby reducing the time spent by installers on multiple measurements and adjustments and improving the installation efficiency of the leaf springs.

[0005] An auxiliary positioning device for installing leaf springs in vehicle production according to an embodiment of this application includes: a frame, a first positioning component, and a second positioning component. The first positioning component includes a first telescopic frame, a positioning sleeve, and a clamping member. The first telescopic frame is fixedly connected to the upper part of one side of the frame. The positioning sleeve is disposed at the output end of the first telescopic frame and is symmetrically arranged. The clamping member is disposed on the upper part of the frame. The second positioning component includes a support frame, a bidirectional linear slide rail, a second telescopic frame, a centering member, a lifting member, and a flattening member. The support frame is disposed on the upper part of the frame. The bidirectional linear slide rail is disposed at the bottom of one side of the support frame. The second telescopic frame, the centering member, the lifting member, and the flattening member are all symmetrically arranged. The upper part of the second telescopic frame is fixedly connected to the bottom of the sliding end of the bidirectional linear slide rail. One side of the upper part of the lifting member is fixedly connected to the bottom of the second telescopic frame. The centering member is symmetrically arranged on both sides of the lifting member. The flattening member is disposed on one side of the bottom of the lifting member and is symmetrically arranged on both sides of the lifting member.

[0006] According to an embodiment of this application, a leaf spring mounting auxiliary positioning device for vehicle production has the following advantages: First, the two sides of the first telescopic frame simultaneously push the two positioning sleeves to move in opposite directions, placing the axle on the upper part of one side of the frame, so that the axle is located in the middle of the clamping member. The output end of the first telescopic frame retracts and clamps the positioning sleeves on both sides of the axle. The continuous retraction of the first telescopic frame centers and limits the axle on the side. After centering and limiting, the axle is clamped and positioned by the clamping member. With the cooperation of the support frame and the frame, the support frame is installed on the upper part of the frame. The two sliding ends of the bidirectional linear slide rail drive the movement of the second telescopic frame, the centering member, the lifting member, and the flattening member, respectively, to clamp the leaf spring. The two sides of the lifting member are respectively hung on the two sides of the leaf spring. The centering member performs the centering operation on the leaf spring. Then, the flattening member... Under the action of the output end, the leaf springs are flattened to ensure parallelism between the two leaf springs. Under the action of the bidirectional linear slide rail, the two leaf springs are transported to the upper sides of the axle. When transporting the two leaf springs, the bidirectional linear slide rail controls the edge distance between the leaf springs and the axle to ensure that the edge distance between the two leaf springs and the axle is moderate. Finally, under the push of the output end of the second telescopic frame, the bottom of the leaf spring is brought into contact with the upper part of the axle to install the leaf spring. In the whole process of use, the axle is centered and fixed. By clamping and positioning the leaf springs, the leaf springs are transported to both sides of the axle, ensuring the relative perpendicularity between the leaf springs and the axle, ensuring the parallelism between the two leaf springs, and ensuring that the edge distance between the two leaf springs and the axle is the same. This reduces the time for installation personnel to measure and adjust multiple times and improves the installation efficiency of the leaf springs.

One end of the first limiting rod is fixedly connected to one side of the push plate, and the other end of the first limiting rod slides through the interior of the lifting rod.

[0017] When installing leaf springs, the leaf springs need to be transported to the operating area. Due to the heavy weight of the axle, a lot of manpower is required to move the axle, which not only increases the workload of the installers, but also wastes time and reduces the efficiency of leaf spring installation.

[0018] According to this application, the system also includes a loading and unloading assembly, which comprises a dual-axis motor, a threaded rod, a lifting block, a second limiting rod, and a horizontal pushing member. The dual-axis motor is fixedly connected to the frame, and the output end of the dual-axis motor is drivenly connected to one end of the threaded rod. The threaded rod is rotatably connected to the frame. The lifting blocks are symmetrically arranged, and the middle part of the threaded rod is threadedly connected to one of the lifting blocks.

One side of the horizontal pushing member is fixedly connected to one side of the first rod body, and one end of the horizontal pushing member is fixedly connected to one side of the lower sleeve.

[0019] The output end of the first telescopic frame drives the horizontal pusher to move, which in turn drives the positioning sleeve to move towards one side of the axle. With the retraction of the output end of the first telescopic frame, the positioning sleeve is secured to the outside of both sides of the axle. The output end of the dual-axis motor drives the rotation of the threaded rod, which in turn drives the lifting block to rise. One lifting block lifts the first telescopic frame, while the other lifting block, under the action of the second limit rod, limits the first telescopic frame. The lifting of the first telescopic frame drives the horizontal pusher to rise, which in turn drives the positioning sleeve to rise. The positioning sleeve then lifts the axle. After being lifted, the axle is transported to one side of the frame with the retraction of the output end of the horizontal pusher. The axle is positioned above the clamping end of the clamping component. The output of the dual-axis motor drives the rotation of the threaded rod, lowering the first telescopic frame. The descent of the first telescopic frame drives the descent of the horizontal pushing component, which in turn drives the locating sleeve and the axle to descend, placing the axle in the middle of the clamping end of the clamping component. After the leaf spring is installed, the output of the dual-axis motor drives the rotation of the threaded rod, which in turn lifts the first telescopic frame. Under the push of the output of the horizontal pushing component, the axle and leaf spring are pushed to one side of the frame for unloading. Throughout the entire process, the axle is loaded, and the axle and leaf spring after installation are unloaded, saving transportation time and improving the installation efficiency of the leaf spring.

[0020] According to this application, the output end of the dual-axis motor is provided with a third gear, and the threaded rod is provided with a fourth gear, the third gear and the fourth gear being meshed together.

[0021] According to this application, the horizontal pusher includes a fourth telescopic member, a first slide, a second slide, and a third slide.

The end of the fourth telescopic member is fixedly connected to one side of the first slide. The output end of the fourth telescopic member is fixedly connected to one side of the third slide.

[0022] When installing leaf springs, the leaf springs need to be installed on one side of the designated face of the axle. Therefore, the angle of the axle needs to be adjusted. Usually, when adjusting the angle of the axle, it is often done manually. After the rotation, it is necessary to manually hold it for a long time. This not only increases the workload of the installers, but also requires a lot of time to adjust the angle of the designated face of the axle, thus reducing the installation efficiency of the leaf springs.

[0023] According to this application, it also includes a rotating assembly, which includes a third telescopic frame, an outer frame, a rotating frame, a drive motor, and a clamping member. One end of the third telescopic frame is fixedly connected to one side of the second rod body, and the output end of the third telescopic frame is fixedly connected to one side of the outer frame. The rotating frame is rotatably connected inside the outer frame. The drive motor is fixedly connected to the outer frame, and the output end of the drive motor is drively connected to the rotating frame. The clamping member is spaced apart inside the rotating frame.

[0024] Driven by the output end of the third telescopic frame, the outer frame is pushed towards the axle side. The outer frame drives the rotating frame, drive motor, and clamping component to move simultaneously. First, the output end of the drive motor drives the rotating frame to rotate, resetting the rotating frame. With the continuous push from the output end of the third telescopic frame, the outer frame and rotating frame are inserted into the outside of the axle. The output end of the clamping component clamps and limits the axle. The output end of the drive motor drives the rotating frame to rotate, which in turn drives the clamping component to rotate. The rotation of the clamping component drives the rotation of the axle, thus adjusting the angle of the designated surface of the axle. Throughout the entire process, the angle adjustment of the designated surface of the axle is achieved through mechanized operations, reducing the workload of the installers and saving time in adjusting the angle of the designated surface of the axle, thereby improving the installation efficiency of the leaf spring.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following description, with reference to the accompanying drawings, describes an auxiliary positioning device for mounting leaf springs in vehicle production according to an embodiment of this application.

[0041] like Figures 1-10 As shown, a vehicle production leaf spring mounting auxiliary positioning device according to an embodiment of this application includes a frame 100, a first positioning component 200, and a second positioning component 300.

[0042] The first positioning component 200 includes a first telescopic frame 210, a positioning sleeve 220, and a clamping member 230. The first telescopic frame 210 is fixedly connected to the upper part of one side of the frame 100. The positioning sleeve 220 is disposed at the output end of the first telescopic frame 210 and is symmetrically arranged. The clamping member 230 is disposed on the upper part of the frame 100. The second positioning component 300 includes a support frame 310, a bidirectional linear slide rail 320, a second telescopic frame 330, a centering member 340, a lifting member 350, and a flattening member 360. The support frame 310 is disposed on the frame 100. At the upper part of 00, the bidirectional linear slide rail 320 is set at the bottom of one side of the support frame 310. The second telescopic frame 330, the centering member 340, the lifting member 350 and the flattening member 360 are all symmetrically arranged. The upper part of the second telescopic frame 330 is fixedly connected to the bottom of the sliding end of the bidirectional linear slide rail 320. The upper part of the lifting member 350 is fixedly connected to the bottom of the second telescopic frame 330 on one side. The centering member 340 is symmetrically arranged on both sides of the lifting member 350. The flattening member 360 is set at one bottom side of the lifting member 350 and is symmetrically arranged on both sides of the lifting member 350.

[0043] The working process of a leaf spring mounting auxiliary positioning device for vehicle production according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0044] First, the output end of the first motor 214 drives the rotation of the first bidirectional threaded rod 213. The first bidirectional threaded rod 213 drives the two first rod bodies 211 and the second rod body 212 to slide together. The first rod body 211 drives the lower sleeve 222 to move, so that the distance between the two lower sleeves 222 is greater than the length of the axle.

[0045] Next, the axle is placed on the upper side of the frame 100, between the two clamping plates. The output end of the first motor 214 drives the rotation of the first bidirectional threaded rod 213, causing the two first rods 211 to retract into the interior of the second rod 212. The first rods 211 drive the movement of the lower sleeve 222 and put it on the outside of the axle. The two first rods 211 retract synchronously, driving the two lower sleeves 222 to push the two sides of the axle synchronously until the axle is centered and limited.

[0046] Subsequently, the output end of the second motor 231 drives the rotation of the second bidirectional threaded rod 232, and the rotation of the second bidirectional threaded rod 232 drives the movement of the two clamping plates to perform clamping and positioning of the axle.

[0047] Then, the output end of the second servo motor 352 drives the rotation of a rotating shaft 353. The transmission connection between the two rotating shafts 353 drives the rotation of the lifting rod 354, which puts the two lifting rods 354 on both sides of the leaf spring. The output ends of the two second telescopic components 341 retract synchronously, driving the two centering plates 342 to center the leaf spring. The output end of the third telescopic component 361 pushes the push plate 362 to push the leaf spring to one side of the lifting rod 354, thus achieving parallel positioning of the two leaf springs.

[0048] Secondly, the output end of the third motor 321 drives the rotation of the third bidirectional threaded rod 322, which in turn drives the movement of the two sliders 323, conveying the second telescopic frame 330, the lifting component 350 and the leaf spring to the top of the axle. The output end of the second telescopic frame 330 pushes the leaf spring down and places it on the top of the axle.

[0049] Therefore, throughout the entire process of use, the axle is centered and fixed. By clamping and positioning the leaf springs, the leaf springs are transported to both sides of the axle, ensuring the relative perpendicularity between the leaf springs and the axle, as well as the parallelism between the two leaf springs. At the same time, it also ensures that the edge distances of the two leaf springs to the axle are the same, thereby reducing the time spent by the installers on multiple measurements and adjustments and improving the installation efficiency of the leaf springs.

One side of the lifting rod 354 is fixedly connected to one side of the rotating shaft 353. The rotating shaft 353 and the lifting rod 354 are symmetrically arranged. The two rotating shafts 353 are connected by transmission. It should be noted that the two rotating shafts 353 are meshed by a gear. The flattening component 360 is located on one side of the bottom of the lifting rod 354.

[0059] According to this application document, such as Figure 8 As shown, the flattening component 360 includes a third telescopic component 361, a push plate 362, and a first limiting rod 363. The end of the third telescopic component 361 is fixedly connected to the lifting rod 354, the output end of the third telescopic component 361 is fixedly connected to one side of the push plate 362, one end of the first limiting rod 363 is fixedly connected to one side of the push plate 362, and the other end of the first limiting rod 363 slides through the interior of the lifting rod 354.

[0060] When installing leaf springs, the leaf springs need to be transported to the operating area. Due to the heavy weight of the axle, a lot of manpower is required to move the axle, which not only increases the workload of the installers, but also wastes time and reduces the installation efficiency of the leaf springs.

[0061] According to this application document, such as Figure 2 and Figure 9As shown, it also includes a loading and unloading assembly 400, which includes a dual-axis motor 410, a threaded rod 420, a lifting block 430, a second limiting rod 440, and a horizontal pushing member 450. The dual-axis motor 410 is fixedly connected to the frame 100, and the output end of the dual-axis motor 410 is connected to one end of the threaded rod 420 for transmission. The threaded rod 420 is rotatably connected to the frame 100. The lifting blocks 430 are symmetrically arranged, and the middle part of the threaded rod 420 is threadedly connected to one lifting block 430. The second limiting rod 440 slides through the interior of another lifting block 430 and is fixedly connected to the frame 100. One side of the horizontal pushing member 450 is fixedly connected to one side of the first rod body 211, and one end of the horizontal pushing member 450 is fixedly connected to one side of the lower sleeve 222.

[0062] The output end of the first telescopic frame 210 drives the horizontal pusher 450 to move, and the output end of the horizontal pusher 450 drives the positioning sleeve 220 to move towards one side of the axle. With the retraction of the output end of the first telescopic frame 210, the positioning sleeve 220 is secured to the outside of both sides of the axle. The output end of the dual-axis motor 410 drives the threaded rod 420 to rotate, and the threaded rod 420 drives the lifting block 430 to rise. One lifting block 430 drives the first telescopic frame 210 to rise, while the other lifting block 430, under the action of the second limit rod 440, limits the first telescopic frame 210. The rise of the first telescopic frame 210 drives the horizontal pusher 450 to rise, and the horizontal pusher 450 drives the positioning sleeve 220 to rise. The positioning sleeve 220 lifts the axle, and the lifted axle retracts with the retraction of the output end of the horizontal pusher 450. The axle is transported to the upper side of the frame, and the axle is positioned above the clamping end of the clamping member 230. The output end of the dual-axis motor 410 drives the rotation of the threaded rod 420, which lowers the first telescopic frame 210. The descent of the first telescopic frame 210 drives the descent of the horizontal pusher 450, which in turn drives the descent of the positioning sleeve 220 and the axle, placing the axle in the middle position of the clamping end of the clamping member 230. After the leaf spring is installed, the output end of the dual-axis motor 410 drives the rotation of the threaded rod 420, which in turn lifts the first telescopic frame 210. Under the push of the output end of the horizontal pusher 450, the axle and leaf spring are pushed to one side of the frame 100 for unloading. Throughout the entire process, the axle is loaded, and the axle and leaf spring after installation are unloaded, saving transportation time and improving the installation efficiency of the leaf spring.

[0063] According to this application document, such as Figure 9 As shown, the output end of the dual-axis motor 410 is provided with a third gear 411, and the threaded rod 420 is provided with a fourth gear 421. The third gear 411 and the fourth gear 421 are meshed and connected.

[0064] According to this application document, such as Figure 9 As shown, the horizontal pusher 450 includes a fourth telescopic member 451, a first slide 452, a second slide 453, and a third slide 454. One side of the first slide 452 is fixedly connected to one end of the first rod 211. One side of the second slide 453 is slidably connected to the inside of the first slide 452. One side of the third slide 454 is slidably connected to the inside of the second slide 453. One side of the third slide 454 is fixedly connected to one side of the lower sleeve 222. The end of the fourth telescopic member 451 is fixedly connected to one side of the first slide 452. The output end of the fourth telescopic member 451 is fixedly connected to one side of the third slide 454.

[0065] When installing leaf springs, they need to be installed on one side of the designated face of the axle. Therefore, the angle of the axle needs to be adjusted. Usually, when adjusting the angle of the axle, it is often done manually. After the rotation, it requires long-term manual support, which not only increases the workload of the installers, but also requires a lot of time to adjust the angle of the designated face of the axle, thus reducing the installation efficiency of the leaf springs.

[0066] According to this application document, such as Figure 2 and Figure 10 As shown, it also includes a rotating assembly 500, which includes a third telescopic frame 510, an outer frame 520, a rotating frame 530, a drive motor 540, and a clamping member 550. It should be noted that the clamping member 550 includes an electric push rod and a clamping plate. The output end of the electric push rod pushes the clamping plate to clamp the axle. One end of the third telescopic frame 510 is fixedly connected to one side of the second rod body 212, and the output end of the third telescopic frame 510 is fixedly connected to one side of the outer frame 520. The rotating frame 530 is rotatably connected inside the outer frame 520. The drive motor 540 is fixedly connected to the outer frame 520, and the output end of the drive motor 540 is drively connected to the rotating frame 530. The clamping members 550 are spaced apart inside the rotating frame 530.

[0067] Driven by the output end of the third telescopic frame 510, the outer frame 520 is pushed towards the axle side. The outer frame 520 drives the rotating frame 530, the drive motor 540, and the clamping member 550 to move simultaneously. First, the output end of the drive motor 540 drives the rotating frame 530 to rotate, resetting the rotating frame 530. With the continuous push of the output end of the third telescopic frame 510, the outer frame 520 and the rotating frame 530 are inserted into the outside of the axle. The output end of the clamping member 550 clamps and limits the axle. The output end of the drive motor 540 drives the rotating frame 530 to rotate, which in turn drives the clamping member 550 to rotate. The rotation of the clamping member 550 drives the rotation of the axle, thus adjusting the angle of the designated surface of the axle. Throughout the entire process, the angle adjustment of the designated surface of the axle is achieved through mechanized operations, reducing the workload of the installers and saving time in adjusting the angle of the designated surface of the axle, thereby improving the installation efficiency of the leaf spring.

One drive motor 540 is located on the upper side of the outer frame 520, and the other drive motor 540 is located on the bottom side of the outer frame 520. The output end of the drive motor 540 is provided with a fifth gear 541, and the rotating frame 530 is provided with a gear ring 531. The fifth gear 541 is meshed with the gear ring 531.

[0070] It should be noted that the first telescopic component 334, the second telescopic component 341, the third telescopic component 361, the fourth telescopic component 451, and the fifth telescopic component 511 are all equipped with electric push rods, electric cylinders, pneumatic cylinders, and hydraulic cylinders.
