Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically a high-load automobile component frame for assembly line production. Background Technology

[0002] These are tooling fixtures on the assembly line of an automobile manufacturing plant. They are mainly used for temporary storage and transfer of automobile parts to be assembled next to the production line, or as a support platform during the assembly process. They are auxiliary tools in the production process.

[0003] In the field of automotive component testing, existing supports mostly adopt single support column, single-sided hydraulic or fixed claw structure, which have problems such as easy support shaking under heavy load, time-consuming clamping width adjustment, and local stress concentration caused by rigid clamping blocks, making it difficult to meet the requirements of high load, multiple size and high precision testing. Utility Model Content

[0004] The purpose of this invention is to provide a high-load automotive component rack for assembly line production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-load automotive component frame for assembly line production, comprising a base, a central support column installed at the upper center of the base, two side plates symmetrically installed at the upper end of the base, a sliding groove opened at one end of the two side plates facing each other, a hydraulic rod installed inside the sliding groove, a crossbeam jointly installed at the upper ends of the two hydraulic rods, side grooves opened at both the front and rear ends of the crossbeam, a double-helical threaded rod rotatably connected inside the side groove, a movable plate symmetrically installed on the surface of the double-helical threaded rod, a clamping plate jointly installed at the lower ends of the two movable plates on the same side, and a plurality of equidistantly arranged clamping blocks installed at one end of each clamping plate facing each other.

[0006] Preferably, a reinforcing plate is installed at the connection between the side plate and the base.

[0007] Preferably, the upper end of the base is provided with multiple mounting slots, the interior of the mounting slots is rotatably connected to a guide threaded rod, the surface of the guide threaded rod is threadedly connected to a sliding block, the upper end of the sliding block is equipped with an electric push plate, and the upper ends of the two electric push plates on the same side are jointly equipped with a support plate.

[0008] Preferably, two grooves are symmetrically formed at the inner edge of the base, and a drive assembly is installed inside the groove. The drive assembly is connected to two guide threaded rods on the same side.

[0009] Preferably, the lower rectangular array of the base is equipped with multiple adjustable feet.

[0010] Preferably, the drive assembly includes a drive shaft, a drive gear, a driven gear, and a drive motor. The drive motor is fixedly installed inside the groove. The drive gear is installed at the output end of the drive motor. Driven gears are meshed on both sides of the drive gear. The drive shaft is installed at the end of the driven gear facing the guide threaded rod. The drive shaft is connected to the guide threaded rod. A support shaft is installed at one end of both the drive gear and the driven gear. The support shaft is rotatably connected to the inner wall of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The high-load automotive component rack used in this production line achieves stable support under heavy loads through a collaborative structure of "central support column + double hydraulic rods + double helical threaded rods". At the same time, the double helical threaded rods drive the symmetrical moving plate to extend and retract synchronously, which can quickly adapt to automotive components of different widths. The equidistant clamping blocks on the clamping plate evenly distribute the clamping force, avoid local stress concentration, and ensure that the components do not shift or deform under high loads, thus meeting the accuracy requirements of the testing scenario.

[0013] 2. The high-load automotive component frame used in this production line is reinforced with a reinforcing plate at the connection between the side plate and the base. This effectively disperses the load transmitted by the hydraulic rod and the crossbeam, preventing deformation or cracking caused by stress concentration at the connection between the side plate and the base, and extending the service life of the frame.

[0014] 3. The high-load automotive component frame used in this production line consists of a guide threaded rod, sliding block, and pneumatic push plate on the base, forming a liftable support plate. With the gear transmission adjustment of the drive component, the height and level of the support plate can be adjusted synchronously to adapt to automotive components with different bottom shapes (such as arc-shaped and stepped shapes), avoiding unstable support caused by uneven bottom surfaces of the components.

[0015] 4. The high-load automotive component frame used in this production line adopts a gear transmission scheme of "drive motor + driving gear + driven gear + drive shaft". It has high transmission efficiency and low noise. The gear is rotatably connected to the inner wall of the groove through the support shaft. The structure is compact and occupies little space, which is suitable for the installation needs of narrow areas of the production line. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 3As shown, the high-load automotive component rack for assembly line production in this embodiment includes a base 1. A central support column 6 is installed at the upper center of the base 1. The central support column 6 is a hydraulic telescopic column, which can move vertically to provide bottom support for the automotive components. Two side plates 3 are symmetrically installed on the upper end of the base 1. A sliding groove 21 is opened at the opposite end of the two side plates 3. The two side plates 3 are the same size. The sliding groove 21 is located on the upper part of the side plates 3, and the uppermost end is an open opening. A hydraulic rod 8 is installed inside the sliding groove 21. The hydraulic rod 8 is hydraulically driven and can move up and down inside the sliding groove 21. The two hydraulic rods 8 are connected by a crossbeam 5 at their upper ends. The two ends of the crossbeam 5 are slidably connected to the two sliding grooves 21. The crossbeam 5 can slide vertically within the two sliding grooves 21 under the action of the two hydraulic rods 8. The two hydraulic rods 8 are controlled by a flow divider-combiner valve connected to an external hydraulic supply control system. During the oil supply phase, the oil output from the pump first enters the flow divider valve. The throttling orifice within the valve forces the flow to be evenly distributed to the rodless chambers of the two cylinders (assuming the cylinders rise synchronously), pushing the pistons to extend synchronously. During the oil return phase, the oil in the rod chambers of the cylinders merges through the flow combiner valve and returns to the oil tank. The valve's internal throttling orifice also evenly distributes the return oil flow, ensuring synchronous piston retraction. Side grooves 9 are provided at both the front and rear ends of the crossbeam 5. Double-threaded rods 10 are rotatably connected inside the side grooves 9. Two drive devices are symmetrically installed inside the crossbeam 5, each connected to one end of a double-threaded rod 10. The drive devices are servo motors, capable of rotating the double-threaded rods 10. The double-threaded rods 10 are existing devices and will not be described in detail. Moving plates 11 are symmetrically installed on the surface of the double-threaded rods 10. When the double-threaded rods 10 rotate, the moving plates 11 will... Moving along the length of the double-helix threaded rod 10, it should be noted that the two moving plates 11 mounted on the surface of the same double-helix threaded rod 10 will move in opposite directions. The lower ends of the two moving plates 11 on the same side are jointly mounted with clamping plates 12. Under the effect of the moving plates 11, the two clamping plates 12 will move in opposite directions, thereby achieving the clamping effect on the car parts. Multiple clamping blocks 13 are mounted at equal intervals on the opposite ends of the two clamping plates 12. The multiple equal-interval clamping blocks 13 can clamp different types of car parts.

[0023] Specifically, a reinforcing plate 4 is installed at the connection between the side plate 3 and the base 1. The reinforcing plate 4 is L-shaped, and its two side walls are connected to the side plate 3 and the base 1 respectively by bolts, which can provide strong stability for the side plate 3.

[0024] Furthermore, the upper end of the base 1 is provided with multiple mounting slots 17. A guide threaded rod 18 is rotatably connected inside the mounting slot 17. A sliding block 19 is threadedly connected to the surface of the guide threaded rod 18. An electric push plate 20 is mounted on the upper end of the sliding block 19. A support plate 7 is mounted on the upper end of two electric push plates 20 on the same side. When the guide threaded rod 18 rotates, the sliding block 19 moves along the length of the guide threaded rod 18. The electric push plate 20 mounted on the upper end of the sliding block 19 can drive the support plate 7 to move vertically. The two support plates 7 can provide bottom support for the automotive components. The support effect, together with the central support column 6, forms a three-point support. The movement principle of the two electric push plates 20 is that an absolute encoder or laser displacement sensor is installed at the center or both ends of the electric push plate 20 to detect the actual displacement of the electric push plate 20 in real time and feed it back to the main controller (such as a motion controller). Each electric push plate 20 motor is equipped with an encoder (feedback of its own displacement). The main controller compares the actual displacement of the electric push plate 20 with the feedback displacement of the two push rods, calculates the difference, and dynamically adjusts the input commands of the two motors. The above principle is a relatively mature existing technology, so it will not be described in detail.

[0025] Furthermore, two grooves 14 are symmetrically formed on the inner edge of the base 1. A drive assembly 15 is installed inside the groove 14. The drive assembly 15 is connected to two guide threaded rods 18 on the same side. The drive assembly 15 can drive the two guide threaded rods 18 on the same side to rotate synchronously.

[0026] Furthermore, the lower rectangular array of the base 1 is equipped with multiple adjustable feet 2, which can change the height of the base 1. The adjustable feet 2 are existing conventional technology.

[0027] Furthermore, the drive assembly 15 includes a drive shaft 1501, a drive gear 1502, a driven gear 1503, and a drive motor 1504. The drive motor 1504 is fixedly installed inside the groove 14. The drive gear 1502 is installed at the output end of the drive motor 1504. The driven gears 1503 are meshed on both sides of the drive gear 1502. The drive shaft 1501 is installed at the end of the driven gear 1503 facing the guide threaded rod 18. The drive shaft 1501 is connected to the guide threaded rod 18. One end of the drive gear 1502 and the driven gear 1503 are both... A support shaft 16 is installed, which is rotatably connected to the inner wall of the groove 14. The drive motor 1504 can drive the drive gear 1502 to rotate. The drive gear 1502 can drive the driven gears 1503 on both sides to rotate. The two driven gears 1503 can drive the drive shaft 1501 to rotate. The two drive shafts 1501 then drive the two guide thread rods 18 to rotate synchronously. The drive gear 1502 and the driven gears 1503 are both supported by the support shaft 16, thereby stabilizing the positions of the drive gear 1502 and the driven gears 1503.

[0028] The usage method of this embodiment is as follows: According to the size and dimensions of the car part, it is placed on the upper end of the central support column 6, and the height position of the crossbeam 5 is changed by driving the two hydraulic rods 8 to rise and fall. The double-helical threaded rod 10 is driven to rotate by the drive device, which in turn drives the moving plate 11 on the surface to move. The moving plate 11 drives the clamping plate 12 to move, and the two clamping plates 12 drive the clamping blocks 13 to move towards each other, which can clamp the car part. The bottom is supported by the active support column and two adjustable height support plates 7 for three-point support, which can meet the high load support and clamping function of the car part to meet the needs of the user.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
