Description

Technical Field

[0001] This utility model relates to a vehicle frame positioning device, and more particularly to a vehicle frame positioning device, belonging to the field of vehicle frame processing technology. Background Technology

[0002] The chassis is a frame structure spanning the front and rear axles of a car, commonly known as a beam, and is the base of the vehicle. It generally consists of two longitudinal beams and several transverse beams, supported on the wheels via the suspension system, front axle, and rear axle. The chassis must possess sufficient strength and rigidity to withstand the vehicle's loads and impacts transmitted from the wheels. The function of the chassis is to support and connect the various assemblies of the car, maintaining their relatively correct positions, and bearing various loads from both inside and outside the vehicle.

[0003] In the prior art, such as the utility model with application number 201821781553.5, a frame assembly positioning device is disclosed. This utility model adjusts and fixes the distance between the support plates through a manual adjustment mechanism, and then moves the two frame positioning blocks inward through an automatic positioning mechanism. The frame body is quickly and securely fixed without damage through an anti-damage mechanism. This solves the problem that existing frame assembly positioning devices cannot be conveniently adjusted and fixed. This frame assembly positioning device has the advantages of convenient adjustment and fixation, and improves its assembly and clamping efficiency.

[0004] The above-mentioned applications still have shortcomings:

[0005] The base plate of this type of frame assembly positioning device has no movable function. The device is fixed in a specific work position and cannot adapt to multi-work position collaborative operation (such as the flow between welding, inspection and assembly work positions). It cannot flexibly adjust the work position and cannot meet many usage requirements.

[0006] To address this issue, a chassis positioning device was designed. Utility Model Content

[0007] The main objective of this invention is to provide a vehicle frame positioning device to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A vehicle frame positioning device includes a support block, with fixing blocks fixed on both sides of the support block. A motor is symmetrically mounted on the top of one end of the support block, and a rotating shaft is fixedly mounted on the output shaft of each motor. Limit bearings are fitted on both ends of the rotating shaft, and a lifting block is fixed to the bottom of the limit bearing. The bottom of the lifting block is fixedly connected to the top of the support block. Gears are symmetrically fixed on the outer side of the rotating shaft. Guide rods are uniformly fixed on the top of the support block near the fixing block. A support frame is mounted on the top of the guide rod, and a limit component is provided on the support frame. U-shaped plates are fitted on the outer side of each guide rod. Sliding holes are provided at the connection between the U-shaped plates and the guide rods.

[0015] Preferably, a limiting pad is provided on one side of the limiting plate and one side of the fixing plate, and the limiting pad is a rubber pad.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, through the combined use of a motor-driven gear meshing mechanism, enables the universal wheels to extend and retract vertically, achieving efficient transmission. The guide plate and guide rod precisely limit the positioning of the U-shaped plate, ensuring stable extension and retraction.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

These terms are 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, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a vehicle frame positioning device, including a support block 1. Fixing blocks 2 are fixed to both sides of the support block 1. A motor 3 is symmetrically mounted on the top of one end of the support block 1. A rotating shaft 4 is fixedly mounted on the output shaft of each motor 3. Limiting bearings 13 are sleeved on both ends of the rotating shaft 4. A lifting block 14 is fixed to the bottom of the limiting bearing 13, and the bottom of the lifting block 14 is fixedly connected to the top of the support block 1. Gears 5 are symmetrically fixed to the outer side of each rotating shaft 4. The top of the support block 1 near the fixing block 2 is uniformly... A guide rod 6 is fixed, and a support frame 7 is installed on the top of the guide rod 6. A limit component 8 is provided on the support frame 7. A U-shaped plate 9 is fitted on the outer side of the guide rod 6. A sliding hole is opened at the connection between the U-shaped plate 9 and the guide rod 6. A side plate 11 is fixed on the side of the U-shaped plates 9 that are close to each other. A rack 12 that meshes with the gear 5 is evenly arranged on the side of the side plate 11 that is close to the gear 5. A universal wheel 10 is installed at both ends of the U-shaped plate 9. A guide plate 15 that is slidably connected to one side of the U-shaped plate 9 is fixed on the top of the fixing block 2.

[0029] After the support block 1 is moved to a suitable position by the casters 10, the motor 3 is started. The motor 3 drives the shaft 4 and gear 5 to rotate. The gear 5 drives the side plate 11 to move upward through the meshing rack 12. With the guide plate 15 and guide rod 6 simultaneously limiting the U-shaped plate 9, the side plate 11 drives the U-shaped plate 9 to move upward until the U-shaped plate 9 drives the casters 10 at both ends to leave the ground and suspend in the air, while the support block 1 contacts the ground. The motor 3 is then turned off, and the overall weight of the support block 1 is transmitted to the ground through the support block 1. The casters 10 do not bear any weight, making the support block 1 more stable as a whole. Example

[0030] The solution in Example 1 will be further described below with reference to its specific working method.

[0031] like Figure 1 As shown, in a preferred embodiment, based on the above method, the limiting component 8 further includes an electric push rod 801 and a limiting frame 802. The electric push rods 801 are evenly arranged on the top of the support frame 7. The telescopic end of the electric push rod 801 is equipped with the limiting frame 802. An electric push rod 803 is installed on one side of the limiting frame 802. The telescopic end of the electric push rod 803 passes through and extends into the interior of the limiting frame 802. A limiting plate 805 is installed on the telescopic end of the electric push rod 803, and the limiting plate 805 is slidably connected to the interior of the limiting frame 802. A fixing plate 804 is fixedly installed inside the limiting frame 802 at a position away from the limiting plate 805.

[0032] The distance between the limiting plate 805 and the fixed plate 804 is adjusted by driving the electric push rod 803 to move the limiting plate 805, thereby limiting the frame body.

[0033] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the U-shaped plate 9 is further provided with balls 17 evenly arranged on the side near the guide plate 15, and the guide plate 15 is provided with guide grooves 16 that match the balls 17 evenly on the side near the U-shaped plate 9, and the balls 17 are slidably connected to the inside of the guide grooves 16.

[0034] The side plate 11 rotates under the meshing of the gear 5, which drives the U-shaped plate 9 to move upward. The U-shaped plate 9 drives the ball 17 to slide upward along the inside of the guide groove 16 on one side of the guide plate 15, which plays a guiding and limiting role when the U-shaped plate 9 moves up and down. The ball 17 is in rolling connection with the guide groove 16, resulting in low friction and smoother up and down movement of the U-shaped plate 9 and the universal wheel 10.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, the bottom of each fixing block 2 is further fixed with a reinforcing pad, and the bottom of the reinforcing pad is provided with anti-slip texture.

[0036] The anti-slip force at the bottom of the fixing block 2 is increased by adding a reinforcing pad and anti-slip texture, thereby further improving the overall stability.

[0037] like Figure 1As shown, in a preferred embodiment, based on the above method, a bidirectional lead screw is uniformly rotatably installed inside the support frame 7, and the end of the bidirectional lead screw passes through and extends to the outside of the support frame 7. A slider is threadedly installed on the outside of the bidirectional lead screw, and the slider is fixedly connected to the bottom of the electric push rod 801. A limit opening is opened at the connection between the support frame 7 and the electric push rod 801.

[0038] By rotating the bidirectional lead screw to move the slider and the electric push rod 801, the distance and position between the limit components 8 can be adjusted to achieve basic adjustable functions.

[0039] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a protective layer is further provided on the outer side of the guide rod 6, and the protective layer is a lubricating coating.

[0040] The lubricating coating protects the outside of the guide rod 6, making the sliding of the U-shaped plate 9 smoother.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, a limiting pad is provided on one side of the limiting plate 805 and one side of the fixing plate 804, and the limiting pad is a rubber pad.

[0042] Rubber's high elasticity effectively cushions and absorbs shocks, reducing the impact force during collisions or movement between components and protecting the equipment structure from damage. Example

[0043] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0044] After the support block 1 is moved to a suitable position by the casters 10, the motor 3 is started. The motor 3 drives the shaft 4 and gear 5 to rotate. The gear 5 drives the side plate 11 to move upward through the meshing rack 12. Under the simultaneous limitation of the girder plate 9 by the guide plate 15 and the guide rod 6, the side plate 11 drives the girder plate 9 to move upward. The girder plate 9 drives the ball bearing 17 to slide upward along the guide groove 16 on one side of the guide plate 15, so that the casters 10 at both ends of the girder plate 9 do not contact the ground. After the support block 1 contacts the ground, the motor 3 is turned off. The weight of the support block 1 is transferred to the ground through the support block 1, while the casters 10 do not bear the weight, making the support block 1 more stable. After the frame is placed on the limiting component 8, the limit plate 805 is moved by the electric push rod 803 to adjust the distance between the limit plate 805 and the fixed plate 804, thereby limiting the frame body.

[0045] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
