Description

Technical Field

[0001] This utility model relates to the field of aluminum chassis crossbeam technology, and in particular to an aluminum chassis crossbeam positioning component and chassis parts assembly equipment. Background Technology

[0002] The aluminum chassis crossbeam positioning assembly is used to quickly and accurately fix the aluminum chassis crossbeam in a predetermined position to ensure assembly accuracy. At the same time, the assembly equipment works in conjunction with the positioning assembly to achieve rapid chassis assembly, thereby enabling large-scale production.

[0003] Existing beam positioning components typically assemble the beam directly to the chassis after positioning and placing it. However, when errors occur between the beam and the chassis during assembly, the positioning component needs to move synchronously with the beam. Due to the overall movement, the entire device is quite bulky and difficult to align. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as overall movement, bulky equipment, and difficulty in alignment, and to propose an aluminum chassis crossbeam positioning component and chassis parts assembly equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum chassis crossbeam positioning assembly includes:

[0007] Base frame,

[0008] The first lead screw is horizontally disposed within the base frame;

[0009] The second lead screw is longitudinally disposed within the base frame, and the first lead screw is located above the second lead screw;

[0010] A nut is disposed inside the base frame, and both the first lead screw and the second lead screw are threadedly connected to the nut;

[0011] A placement plate is positioned above the nut;

[0012] Multiple positioning pins are fixedly installed on the top of the placement plate.

[0013] In one possible design, the base frame is provided with first sliding grooves on both the left and right sides, and a second slider is slidably connected in each of the two first sliding grooves. The first lead screw is rotatably connected between the two second sliders.

[0014] In one possible design, the base frame is provided with second sliding grooves on both the front and rear sides, and a first slider is slidably connected in each of the two second sliding grooves. The second lead screw is rotatably connected between the two first sliders.

[0015] In one possible design, slide rods are fixedly connected to the top left and right sides of the base frame, and U-shaped carriages are slidably connected to the two slide rods. A mating block is fixedly connected to the top of the U-shaped carriage, and a sliding frame is fixedly connected to the bottom of the placement plate. The sliding frame slidably engages with the mating block.

[0016] In one possible design, there are two sliding frames, each slidingly engaging with one of the two mating blocks.

[0017] The chassis parts assembly equipment includes an aluminum chassis beam positioning assembly and a scissor lift frame, which is fixedly installed between the placement plate and the nut.

[0018] In this application, a crossbeam is placed on a placement plate, and the through holes of the crossbeam are aligned with multiple positioning pins to achieve a positioning effect. When the crossbeam is misaligned with the chassis, the second lead screw or the first lead screw can be rotated according to the misalignment position. When the second lead screw rotates, the thread on the outer wall of the second lead screw drives the nut to move. The nut is connected to the placement plate through the support frame, support bracket, and electric push rod, which can drive the placement plate to move back and forth on the base frame. At the same time, the two sliding frames at the bottom of the placement plate drive the mating block at the bottom. The U-shaped slide at the bottom of the mating block slides on the slide rod. Meanwhile, the first lead screw slides in the two first slide grooves through the second sliders at both ends. When the first lead screw is rotated, the thread on the outer wall of the first lead screw drives the nut to move laterally. The first sliders at both ends of the second lead screw slide in the two second slide grooves. The nut drives the placement plate to move. The two sliding frames at the bottom of the placement plate slide on the two mating blocks. Then, the electric push rod is energized, and the output shaft of the electric push rod pushes the two support brackets, thereby adjusting the height of the placement plate. Finally, the bolt is passed through the crossbeam to connect it to the base plate.

[0019] Beneficial effects: In this utility model, the aluminum chassis crossbeam positioning component and chassis parts assembly equipment, the crossbeam is placed on the display plate, so that the through hole of the crossbeam is aligned with multiple positioning pins, which can quickly achieve positioning, effectively improve assembly efficiency, reduce assembly errors, and ensure the assembly quality of chassis parts.

[0020] In this utility model, when the crossbeam positioning component and chassis parts assembly equipment of aluminum chassis are misaligned with the chassis, the second lead screw or the first lead screw can be rotated accordingly to drive the placement plate to move back and forth and laterally. The height of the placement plate can also be adjusted by an electric push rod, which can easily cope with various misalignment situations and enhance the assembly adaptability.

[0021] This invention features precise and convenient positioning, high assembly efficiency and quality, and flexible adjustment, effectively addressing the misalignment problem between the crossbeam and the chassis, and providing reliable assurance for the assembly of chassis parts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In one embodiment: Refer to Figure 1 An aluminum chassis crossbeam positioning assembly includes a base frame 1. A first lead screw 6 is horizontally mounted inside the base frame 1, and a second lead screw 8 is vertically mounted inside the base frame 1, with the first lead screw 6 positioned above the second lead screw 8. A nut 7 is located inside the base frame 1, through which both the first lead screw 6 and the second lead screw 8 are threaded. A placement plate 2 is fixedly connected above the nut 7, and multiple positioning pins 3 are mounted on the top of the placement plate 2 for aligning the through holes of the crossbeam. The crossbeam is placed on the placement plate 2, aligning the through holes of the crossbeam with the multiple positioning pins 3 for quick positioning. If misalignment occurs between the crossbeam and the chassis, the second lead screw 8 or the first lead screw 6 is rotated according to the direction of misalignment. When the second lead screw 8 is rotated, it drives the nut 7 to move via its thread, causing the placement plate 2 to move back and forth on the base frame 1. When the first lead screw 6 is rotated, it drives the nut 7 to move via its thread, causing the placement plate 2 to move left and right on the base frame 1.

[0029] Reference Figure 2The base frame 1 has a first slide groove 11 on each of its left and right sides. A second slider 13 is slidably connected inside each first slide groove 11, and the two ends of a first lead screw 6 are rotatably connected to the two second sliders 13 respectively. The base frame 1 also has a second slide groove 12 on each of its front and rear sides. A first slider 9 is slidably connected inside each second slide groove 12, and the two ends of a second lead screw 8 are rotatably connected to the two first sliders 9 respectively. When the placement plate 2 moves longitudinally, the two second sliders 13 move synchronously within the two first slide grooves 11. When the placement plate 2 moves laterally, the two first sliders 9 slide and engage within the two second slide grooves 12.

[0030] Reference Figure 2 and Figure 3 A sliding rod 4 is fixedly connected to the top left and right sides of the base frame 1. A U-shaped carriage 5 is slidably connected to the top of each sliding rod 4, and a mating block 10 is fixedly connected to the top of each U-shaped carriage 5. Two sliding frames 14 are fixedly connected to the bottom of the placement plate 2. Each sliding frame 14 slides and engages with the corresponding U-shaped carriage 5 to ensure the stability of the placement plate 2 when it moves. When the placement plate 2 moves longitudinally, the sliding frame 14 at the bottom pushes the mating block 10, causing the U-shaped carriage 5 to slide along the sliding rod 4. When the placement plate 2 moves laterally, the sliding frame 14 at the bottom slides and engages with the mating block 10.

[0031] This application can be used in the field of aluminum chassis crossbeams, or in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 1 and Figure 4 The chassis parts assembly equipment is applied to the field of aluminum chassis crossbeams. The chassis parts assembly equipment includes the above-mentioned aluminum chassis crossbeam positioning components, and also includes a scissor lift frame 15. The scissor lift frame 15 is fixedly installed between the placement plate 2 and the nut 7. The height of the placement plate 2 is adjusted by the extension and retraction of the electric push rod inside the scissor lift frame 15 to meet the height alignment during crossbeam installation.
