Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle frame positioning equipment, specifically to a fixed positioning device for electric vehicle frame production. Background Technology

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. The vehicle frame requires painting during manufacturing to improve its appearance and prevent rust.

[0003] Currently, when painting a vehicle frame, a fixed positioning device is needed to position the frame. However, most existing fixed positioning devices can only be installed and fixed for frames of the same model and size, and cannot be installed and fixed for frames of different sizes, which limits their use. Utility Model Content

[0004] This utility model discloses a fixed positioning device for electric vehicle frame production, which aims to solve the technical problem that existing positioning devices can only install and fix frames of the same size and model.

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

[0006] An electric vehicle frame manufacturing and positioning device includes a base, an installation groove on the upper surface of the base, a frame positioning mechanism inside the installation groove, and a drying mechanism on the back of the base.

[0007] The frame positioning mechanism includes a mounting plate rotatably connected to the bottom wall of the mounting groove. The upper surface of the mounting plate has several fixing grooves arranged in a circumferential array. The side of the mounting plate has a rotating opening that extends into the fixing groove. An operating rod is rotatably connected to the inner wall of the rotating opening. A threaded rod is fixedly connected to one end of the operating rod that extends into the fixing groove. A threaded block is threadedly connected to the surface of the threaded rod. Two symmetrical support plates are fixedly connected to the upper surface of the threaded block. A connecting rod is fixedly connected to the opposite face of the two support plates. A positioning abutment is rotatably connected to the surface of the connecting rod. An abutment edge for limiting the positioning abutment is fixedly installed on the upper surface of the threaded block.

[0008] In a preferred embodiment, the lower surface of the threaded block is provided with a guide slider, and the inner bottom wall of the fixing groove is provided with a guide groove for the guide slider to slide.

[0009] By setting a guide slider, the threaded block can drive the positioning plate to move in a specific direction through the rotation of the threaded rod.

[0010] In a preferred embodiment, the surface of the positioning plate is embedded with a protective pad.

[0011] The installation of protective pads can improve the stability of the positioning plate after it is pressed against the frame.

[0012] In a preferred embodiment, the drying mechanism includes a vertical plate fixedly installed on the back of the base. A heating box and a fan are fixedly installed on the back of the vertical plate. The heating box is equipped with heating wires. A ventilation cavity is opened inside the shell of the vertical plate. An air outlet is opened on the front of the vertical plate, which communicates with the interior of the ventilation cavity. The air outlet of the fan extends into the interior of the heating box. An air supply pipe communicating with the interior of the ventilation cavity is provided on the upper surface of the heating box.

[0013] By using a fan and heating box, air can be blown onto the chassis on the mounting plate to speed up the drying of its surface paint.

[0014] In a preferred embodiment, the number of air outlets is several, and the several air outlets are equidistantly arranged on the front of the vertical plate.

[0015] In a preferred embodiment, a motor is embedded on the left side surface of the base, the output shaft of the motor extends into the interior of the mounting groove and is fixedly connected to a drive bevel gear, and a driven bevel gear that meshes with the drive bevel gear is embedded on the surface of the mounting plate inside the mounting groove.

[0016] The motor allows the mounting plate to rotate, adjusting the orientation of the frame after positioning.

[0017] As can be seen from the above, the electric vehicle frame production fixing and positioning equipment provided by this utility model has the following technical effects.

[0018] Firstly, the threaded block moves the positioning plate corresponding to the frame body by rotating the threaded rod. The frame is fixed and positioned by multiple positioning plates that abut against it in an inward-expanding manner. During this process, since the positioning plates are rotatably connected, the remaining positioning plates that are not needed can be folded and stored in the fixing groove, avoiding the obstruction of the installation of different sized frames due to the presence of extra positioning plates. This allows the positioning device to be adapted to different sized frames, improving its adaptability.

[0019] Secondly, the motor drives the mounting plate to rotate through the active and driven bevel gears, which can adjust the orientation of the frame after it is fixed on the mounting plate, facilitating subsequent painting work. After the painting work is completed, the heating wire generates heat in the heating box. At this time, the fan transports the heat in the heating box into the ventilation chamber through the air duct and blows it out through several air outlets. The warm air can speed up the drying speed of the paint on the frame and reduce the drying time required for painting. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Reference Figures 1-5 An electric vehicle frame manufacturing and positioning device includes a base 1, an installation groove on the upper surface of the base 1, a frame positioning mechanism inside the installation groove, and a drying mechanism on the back of the base 1.

[0028] The frame positioning mechanism includes a mounting plate 2 rotatably connected to the bottom wall of the mounting groove. The upper surface of the mounting plate 2 has several fixing grooves arranged in a circular array. The side of the mounting plate 2 has a rotating opening that extends into the fixing groove. An operating rod 3 is rotatably connected to the inner wall of the rotating opening. A threaded rod 4 is fixedly connected to one end of the operating rod 3 that extends into the fixing groove. A threaded block 5 is threadedly connected to the surface of the threaded rod 4. Two symmetrical support plates 6 are fixedly connected to the upper surface of the threaded block 5. A connecting rod is fixedly connected to the opposite face of the two support plates 6. A positioning abutment 7 is rotatably connected to the surface of the connecting rod. An abutment edge 8 for limiting the positioning abutment 7 is fixedly installed on the upper surface of the threaded block 5.

[0029] The lower surface of the threaded block 5 is provided with a guide slider 9, and the inner bottom wall of the fixed groove is provided with a guide groove for the guide slider 9 to slide. Under the guidance of the guide slider 9, the threaded block 5 can drive the positioning plate 7 to move in a directional manner through the rotation of the threaded rod 4.

[0030] The surface of the positioning plate 7 is embedded with a protective pad 10. The protective pad 10 can improve the stability of the positioning plate 7 after it abuts against the frame.

[0031] Reference Figure 5 In a preferred embodiment, the drying mechanism includes a vertical plate 11 fixedly installed on the back of the base 1. A heating box 12 and a fan 13 are fixedly installed on the back of the vertical plate 11. An electric heating wire 14 is provided inside the heating box 12. A ventilation cavity 15 is opened inside the shell of the vertical plate 11. An air outlet 16 communicating with the inside of the ventilation cavity 15 is opened on the front of the vertical plate 11. The air outlet end of the fan 13 extends into the inside of the heating box 12. An air supply pipe 17 communicating with the inside of the ventilation cavity 15 is provided on the upper surface of the heating box 12.

[0032] By using the fan 13 and the heating box 12, air can be blown onto the frame on the mounting plate 2 to speed up the drying of its surface paint.

[0033] There are several air outlets 16, which are equidistantly arranged on the front of the vertical plate 11.

[0034] Reference Figure 2 and Figure 5 In a preferred embodiment, a motor 18 is embedded on the left side surface of the base 1, the output shaft of the motor 18 extends into the interior of the mounting groove and is fixedly connected to a drive bevel gear 19, and a driven bevel gear 20 that meshes with the drive bevel gear 19 is embedded on the surface of the mounting plate 2 located inside the mounting groove.

[0035] The motor 18 can drive the mounting plate 2 to rotate, which can adjust the orientation of the frame after positioning.

[0036] Working principle: During use, place the vehicle frame to be painted on the mounting plate 2, and rotate the corresponding operating lever 3 to drive the threaded rod 4 to rotate. Under the guidance of the guide slider 9, the threaded block 5 can move the positioning plate 7 corresponding to the frame body through the rotation of the threaded rod 4 until the positioning plate 7 abuts against the frame body. By having multiple positioning plates 7 abut against the frame in an inward-expanding manner, the frame can be fixed and positioned. During this process, since the positioning plates 7 are rotatably connected, the remaining positioning plates 7 that are not in use can be folded and stored in the fixing groove to avoid unnecessary positioning. The presence of the abutment 7 hinders the installation of frames of different sizes. At the same time, the operation of the motor 18 drives the mounting plate 2 to rotate through the active bevel gear 19 and the driven bevel gear 20, which can adjust the orientation of the frame fixed on the mounting plate 2, providing convenience for subsequent painting work. After the painting work is completed, the operation of the heating wire 14 generates heat in the heating box 12. At this time, the operation of the fan 13 transports the heat in the heating box 12 into the ventilation chamber 15 through the air duct 17 and blows it out through several air outlets 16. Under the blowing of warm air, the drying speed of the paint surface of the frame can be accelerated.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
