Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a tooling for electrophoretic coating of new energy vehicle hoods to prevent oil stains from dripping. Background Technology
[0002] Flow marks on the hood after electrophoresis are a common process defect in the automotive painting industry, especially prominent during the drying and curing process of the electrophoretic paint film. Flow marks appear as irregular circular or linear spots on the surface, with a darker color than the surrounding paint film (possibly accompanied by gloss differences). In severe cases, they can lead to pinholes or decreased adhesion of the electrophoretic paint film. Addressing flow marks increases sandpaper costs and also creates new problems, such as paint particle clusters caused by sanding dust. Therefore, this invention proposes a tooling for preventing oil stain dripping during electrophoresis on the hood of new energy vehicles. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a tooling for preventing oil stains from dripping during electrophoresis on the hood of a new energy vehicle, so as to solve the problem of flow marks in traditional electrophoresis.
[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a tooling for preventing oil stains from dripping onto the hood of a new energy vehicle, including a liquid receiving tray, wherein a positioning seat is movably connected to one end of the bottom of the liquid receiving tray to adjust and fix the height of one end of the liquid receiving tray;
[0005] The bottom of the liquid receiving tray is movably connected to an adjusting seat at a position away from the positioning seat, so as to adjust the tilt of the other end of the liquid receiving tray in coordination with the positioning seat.
[0006] The present invention is further configured such that: both sides of the liquid receiving tray and one end face are fixedly connected with bent edges, and the liquid receiving tray is made of aluminum alloy, and a polytetrafluoroethylene anti-stick coating is sprayed on its surface.
[0007] The above technical solution prevents dripping liquid from flowing out of the liquid receiving tray by using the bent edge, while the sprayed anti-stick coating can extend the service life of the liquid receiving tray.
[0008] The present invention is further configured such that: the positioning seat includes a threaded sleeve, an adjusting ball is fixedly connected to the top of the threaded sleeve, and the adjusting ball is movably connected to the inside of the movable groove provided at the bottom of the liquid receiving tray; a threaded support rod is threadedly connected to the inner wall of the threaded sleeve, and a suction cup is sleeved on the bottom of the threaded support rod.
[0009] The above technical solution positions and fixes the positioning seat by a suction cup, and then uses a threaded sleeve to rotate on the threaded support rod to adjust the height of the threaded sleeve on the threaded support rod. The adjusting ball rotates smoothly inside the movable groove to cooperate with stable adjustment.
[0010] The present invention is further configured such that the interior of the movable groove is an arc surface, so as to cooperate with the smooth surface of the adjusting ball to rotate at multiple angles.
[0011] The above technical solution facilitates the adjustment of the liquid receiving tray's height at the other end of the receiving tray, allowing the tray to rotate on the surface of the adjusting ball via the movable groove.
[0012] The present invention is further configured such that: the adjusting seat includes a fixed seat, the bottom of the fixed seat is bonded with an anti-slip rubber pad, the top of the fixed seat is rotatably connected to a rotating frame near one end, the inside of the rotating frame is rotatably connected to a support plate near the bottom, the bottom of the support plate is embedded and connected to the top of the fixed seat, the top of the rotating frame is rotatably connected to a slider, and the slider is slidably connected to a guide rail bolted to the bottom of the liquid receiving tray.
[0013] By rotating the support plate, its bottom is fixed in different embedded slots on the fixed seat, which allows the rotating frame to drive the bottom slider to slide on the guide rail. This causes the rotating frame to lift and lower the liquid receiving tray, thereby adjusting the height of the top liquid receiving tray and adjusting its tilt in conjunction with the positioning seat.
[0014] The present invention is further configured such that: the top of the fixing base is evenly provided with multiple embedding slots, and the bottom of the support plate can be embedded and connected to the interior of the multiple embedding slots.
[0015] The above technical solution allows for adjustment of the tilt of the top liquid receiving tray when the support plate is supported in different embedding slots, facilitating the flow of dripping liquid by utilizing gravity.
[0016] The present invention is further configured such that: a hidden groove is provided on one side of the rotating frame, and the support plate is rotatably engaged and connected to the inside of the hidden groove.
[0017] The above technical solution allows the support plate to be placed inside the hidden slot when the entire tooling is recycled, making it easy to carry and use the tooling and improving its convenience during use.
[0018] The beneficial effects of this utility model are as follows:
[0019] This utility model proposes a new energy vehicle hood electrophoresis anti-oil-spot dripping fixture. By setting a positioning seat and an adjustment seat at the bottom of the liquid receiving tray coated with an anti-stick coating, it can be adjusted to different tilt angles for different electrophoresis processes.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0027] like Figures 1-3As shown, a fixture for preventing oil stains from dripping onto the hood of a new energy vehicle includes a liquid receiving tray 1. Bending edges 11 are fixedly connected to both side walls and one end face of the liquid receiving tray 1. The liquid receiving tray 1 is made of aluminum alloy and has a polytetrafluoroethylene (PTFE) anti-stick coating sprayed on its surface. The bending edges 11 prevent dripping liquid from flowing out of the liquid receiving tray 1, and the anti-stick coating extends the service life of the liquid receiving tray 1. A positioning seat 2 is movably connected to the bottom of the liquid receiving tray 1 near one end for adjusting and fixing the height of one end of the liquid receiving tray 1. The positioning seat 2 includes a threaded sleeve 21, and an adjusting ball 22 is fixedly connected to the top of the threaded sleeve 21, and the adjusting ball 22 is movably connected to the liquid receiving tray. The movable groove 12 at the bottom is curved to allow the smooth surface of the adjusting ball 22 to rotate at multiple angles. This facilitates the adjustment of the height of the receiving tray 1 at the other end of the receiving tray 1. The receiving tray 1 can rotate on the surface of the adjusting ball 22 via the movable groove 12. The inner wall of the threaded sleeve 21 is threadedly connected to a threaded support rod 23. A suction cup 24 is fitted to the bottom of the threaded support rod 23. The positioning seat 2 is positioned and fixed by the suction cup 24. The threaded sleeve 21 is then threadedly rotated on the threaded support rod 23 to adjust the height of the threaded sleeve 21. The adjusting ball 22 rotates smoothly inside the movable groove 12 to facilitate stable adjustment.
[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, an adjusting seat 3 is movably connected to the bottom of the liquid receiving tray 1, away from the positioning seat 2, to adjust the tilt of the other end of the liquid receiving tray 1 in conjunction with the positioning seat 2. The adjusting seat 3 includes a fixed seat 31, and multiple embedding slots 32 are evenly provided on the top of the fixed seat 31. The bottom of the support plate 34 can be embedded and connected to the interior of the multiple embedding slots 32, so that when the support plate 34 is supported in different embedding slots 32, the tilt of the top liquid receiving tray 1 can be adjusted, facilitating the flow of dripping liquid by gravity. The bottom of the fixed seat 31 is bonded with an anti-slip rubber pad, and a rotating frame 33 is rotatably connected to the top of the fixed seat 31 near one end. A hidden groove 331 is provided on one side of the rotating frame 33, and the support plate 34 can be rotatably engaged and connected to the interior of the hidden groove 331, facilitating the adjustment of the entire...

The top of the rotating frame 33 is rotatably connected to the slider 35, and the slider 35 is slidably connected to the guide rail 13 bolted to the bottom of the liquid receiving tray 1. By rotating the support plate 34, its bottom is fixed inside the different embedded slots 32 on the fixed seat 31, so that the rotating frame 33 can drive the bottom slider 35 to slide on the guide rail 13, so that the rotating frame 33 can drive the liquid receiving tray 1 to rise and fall, thereby realizing the height adjustment of the liquid receiving tray 1 at the top, so as to adjust the tilt angle in conjunction with the positioning seat 2.
[0029] In use, the positioning seat 2 is positioned and fixed by the suction cup 24. Then, the threaded sleeve 21 is rotated on the threaded support rod 23 to adjust the height of the threaded sleeve 21 on the threaded support rod 23. The adjusting ball 22 rotates smoothly inside the movable groove 12 to cooperate with stable adjustment. The support plate 34 is rotated so that its bottom is fixed inside different embedding grooves 32 on the fixed seat 31. This allows the rotating frame 33 to drive the bottom slider 35 to slide on the guide rail 13, so that the rotating frame 33 drives the liquid receiving tray 1 to rise and fall, thereby realizing the height adjustment of the liquid receiving tray 1 at the top, so that it can be adjusted in tilt with the positioning seat 2.
