Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber subframes, specifically relating to a grinding and spraying device for carbon fiber subframes. Background Technology

[0002] The subframe is a crucial load-bearing component of a vehicle. Within the chassis, it supports the suspension and connects and mounts other components such as the motor, engine, and steering gear. Therefore, the subframe has requirements regarding modal characteristics, stiffness, strength, and fatigue performance. To meet these performance requirements, subframes typically utilize high-performance, low-density materials, or even combinations of multiple materials. Furthermore, continuous research is underway to select manufacturing processes that match the material properties, thereby achieving higher performance while reducing weight, energy consumption, and carbon emissions.

[0003] Meanwhile, carbon fiber reinforced composite materials are composite materials formed by using carbon fiber or carbon fiber fabric as reinforcement and resin, ceramics, metals, etc. as matrix. Among many lightweight materials, they have high specific strength and high specific stiffness, and the lightweight effect is very obvious. They are already being used in automobile body and chassis components.

[0004] Existing technology uses a hollow, grid-shaped carbon fiber support frame with mounting brackets, typically made of aluminum alloy or other metals, embedded at its four corners. For this type of carbon fiber subframe, painting or sanding is usually done by manually flipping the subframe over on both sides. Furthermore, when painting only one side of the mounting bracket, a masking device is required, which must be held in place by hand to prevent excessive paint pressure from the spray head from dislodging it.

[0005] Therefore, there is an urgent need for a grinding or spraying device for carbon fiber subframes that facilitates flipping and covers the mounting brackets. Utility Model Content

[0006] This utility model proposes a grinding and spraying device for carbon fiber subframes to solve the problems of existing grinding and spraying devices for carbon fiber subframes being inconvenient to flip and requiring the masking parts to be held down by hand.

[0007] To achieve the above objectives, the present invention proposes the following technical solution: A grinding and spraying device for a carbon fiber subframe includes a support frame and a tilting frame. The top of the support frame is a hollow frame, divided into a front half and a rear half; the front half includes two support plates arranged front and rear, and the rear half is a rectangular frame; the bottom surface of the support plates is fixed to the front half of the support frame; the tilting frame is a frame structure, and the front side of the tilting frame is hinged to the rear half of the support frame. The top of the flipping frame is fixed with four positioning rods, and the top of the positioning rods is fixed with a lower cover.

[0008] Preferably, the front half of the support frame includes a bracket and support legs; The support plate is fixed to the bracket, and the bracket is fixed to the support leg.

[0009] Preferably, the bottom surface of the frame is fixed with multiple support legs.

[0010] Preferably, the flipping frame has an open U-shaped frame and includes two oppositely arranged right side frames and left side frames, with a front side frame fixed between the right side frames and the left side frames, and the front side frame is hinged to the front side of the frame.

[0011] Preferably, the front frame is hinged to the front side of the frame by at least two hinges.

[0012] Preferably, the lower cover has positioning holes that match the target carbon fiber subframe.

[0013] Preferably, it also includes an upper cover, and the lower cover is connected to the upper cover by fasteners; the lower cover and the upper cover are assembled into a cuboid by fasteners.

[0014] Preferably, the fasteners between the lower cover and the upper cover are bolts and nuts.

[0015] Preferably, flipping handles are provided on both sides of the flipping frame.

[0016] Preferably, it also includes a front crossbeam and a rear crossbeam; Two front suction cups are fixed on the front crossbeam, and the front suction cups are connected to a first vacuum pump. The first vacuum pump is electrically connected to a first controller. Two rear suction cups are fixed on the rear crossbeam, and the rear suction cups are connected to a second vacuum pump. The second vacuum pump is electrically connected to a second controller. The first vacuum pump and the second vacuum pump are mounted on the support frame.

[0017] Preferably, the first controller is fixed on the front crossbeam or support frame, and the second controller is fixed on the rear crossbeam or support frame.

[0018] The advantages of this utility model are: This invention proposes a flip frame that can be horizontally attached to the top surface of the support frame. The front side of the support frame and the flip frame are hinged. After the flip frame is flipped 180°, it lands on the top surface of the support frame. Instead of directly flipping the carbon fiber subframe, the flip frame is flipped directly, avoiding the possibility of touching the carbon fiber subframe before the paint is dry. On the other hand, each lower cover is connected to an upper cover by fasteners. The lower cover and the upper cover are fitted over the mounting component. The four ends of the carbon fiber subframe are attached to the sides of the lower cover and the upper cover. The lower cover and the upper cover are used to shield the mounting component to protect it. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention. Example

[0022] Please see Figure 1 , 2 As shown in Figures 1 and 3, this utility model provides a grinding and spraying device for a carbon fiber subframe, including a support frame 1, a flipping frame 2, a positioning component, and four upper end caps 4.

[0023] like Figure 4As shown, the four ends of the carbon fiber subframe are hollow and flat. One end of the end is embedded with a non-carbon fiber mounting component. The other end of the mounting component is provided with a ring-shaped bracket 10. The carbon fiber subframe has a left-right symmetrical structure. The top and bottom ends of the ring bracket 10 protrude from one end of the mounting component. The mounting component as a whole is a horizontal T-shape.

[0024] The support frame 1 is fixed to the ground and is a table-like structure, but the tabletop is a hollow frame structure. The top surface of the support frame 1 is divided into a rear half and a front half.

[0025] The flipping frame 2 is horizontally attached to the rear half of the top surface of the support frame 1. The front side of the support frame 1 and the flipping frame 2 are hinged. After the flipping frame 2 is flipped 180°, it falls onto the front half of the top surface of the support frame 1.

[0026] The tilting frame 2 is a frame structure used to surround the carbon fiber subframe. The front side of the tilting frame 2 and the middle position of the support frame 1 are hinged by at least two hinges.

[0027] The top surface of the support frame 1 includes two front-to-back support plates 12 as the front half, and a rectangular frame 11 as the rear half. The front half of the support frame 1 also includes legs and brackets. The bottom surfaces of the support plates 12 are fixed to the brackets, and the brackets are fixedly connected to the legs. The four corners of the tilting frame 2 after tilting are supported by two support plates 12. The bracket is a frame structure that surrounds the tilting frame 2 and the carbon fiber subframe. Multiple legs are fixed to the bottom surface of the frame 11.

[0028] The flipping frame 2 is a U-shaped frame with a rearward opening and includes two oppositely arranged right side frames and left side frames. A front side frame is fixed between the right side frame and the left side frame, and the front side frame is hinged to the front side of the frame 11.

[0029] The positioning component includes four positioning rods 31 fixed to the top surface of the tilting frame 2. Two positioning rods 31 are fixed to both ends of the left side length of the tilting frame 2, and two positioning rods 31 are fixed to both ends of the right side length of the tilting frame 2. The positioning rods 31 are used to reduce the circumferential impact of the tilting frame 2 on the carbon fiber subframe, so as to grind or spray the carbon fiber subframe from the circumferential direction. A lower cover 32 is fixed to the top of each positioning rod 31. The lower cover 32 is used to accommodate the lower half of the mounting component. The lower cover 32 has a positioning hole 321 that matches the bottom end of the ring bracket 10.

[0030] The upper cover 4 has a positioning hole that matches the top of the ring bracket 10, and the upper cover 4 is used to accommodate the upper part of the mounting component. Each lower cover 32 is connected to an upper cover 4 by fasteners, so that even if the flipping frame 2 drives the carbon fiber subframe to flip back and forth, the two ends of the ring bracket 10 are always positioned and clamped in the two positioning holes. The lower cover 32 and the upper cover 4 are assembled into one piece by fasteners, preferably a cuboid.

[0031] The lower cover 32 and the upper cover 4 are fitted over the outside of the mounting component. The interior of the lower cover 32 and the upper cover 4 is hollow. Except for the positioning holes which need to match the ring bracket 10, the internal shape does not need to completely match the mounting component and the carbon fiber subframe. The outline dimension of the internal shape can be greater than or equal to the vertical projection of the mounting component and the carbon fiber subframe. This makes it easier to put the carbon fiber subframe onto the lower cover and the upper cover onto the lower cover.

[0032] Depending on the end thickness of the carbon fiber subframe, the four ends of the carbon fiber subframe can be fitted to the sides of the lower cover 32 and the upper end cover 4, or the lower cover 32 and the upper end cover 4 can cover the four ends of the carbon fiber subframe with a coverage width between 5mm and 15mm, so that the surface of the mounting parts will not be painted. The lower cover 32 and the upper end cover 4 serve to shield the mounting parts. The end faces of the four ends of the carbon fiber subframe may not be painted according to process requirements, or the end faces and the covered areas may be painted separately after this painting is completed.

[0033] In one specific embodiment, the present invention further includes a front crossbeam 5 and a rear crossbeam 6. Two front suction cups 51 are fixed on the front crossbeam 5 and are connected to a first vacuum pump. The vacuum pump is electrically connected to a first controller, which can be fixed to the front crossbeam 5 or the support frame 1. The two front suction cups 51 are used to adsorb the two upper end caps 4 on the front side of the carbon fiber subframe. Two rear suction cups 61 are fixed on the rear crossbeam 6 and are used to adsorb the two upper end caps 4 on the rear side of the carbon fiber subframe. The two rear suction cups 61 are connected to a second vacuum pump, which is electrically connected to a second controller. The second controller can be fixed to the rear crossbeam 6 or the support frame 1. The two rear suction cups 61 are used to adsorb the two upper end caps 4 on the rear side of the carbon fiber subframe. Both vacuum pumps are mounted on the support frame 1.

[0034] When holding the rear crossbeam 5 or the front crossbeam 6, the corresponding upper end cap 4 can be positioned at the four ends of the carbon fiber subframe. This allows the fasteners of the upper end cap 4 to be removed from the carbon fiber subframe at once, and then the two upper end caps 4 can be removed one at a time via the rear crossbeam 5 or the front crossbeam 6 and placed on the external tables on the left and right sides of the support frame 1.

[0035] In one specific embodiment, flipping handles are provided on both sides of the flipping frame 2.

[0036] In one specific embodiment, the lower cover 32 and the upper cover 4 are assembled into a cuboid by fasteners. Each lower cover 32 is connected to the upper cover 4 by two fasteners located on opposite diagonals of the lower cover 32. The fasteners are bolts and nuts. The bolts pass through the lower cover 32 and the upper cover 4 and are connected to the nuts by threads. The axial direction of the bolts is vertical.

[0037] In one specific embodiment, the front-to-back distance of the carbon fiber subframe is less than its left-to-right distance. Therefore, the center line of symmetry of the carbon fiber subframe is located between the left and right sides of the flip frame 2. The flip frame 2 is flipped in the front-to-back direction of the carbon fiber subframe, which facilitates the grinding or spraying of the front and back of the carbon fiber subframe before and after flipping.

[0038] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
