[0001] The utility model relates to the technical field of a vehicle lamp shell processing jig, and more specifically, to a vehicle lamp shell polishing workbench. Background Art

[0002] At present, the headlight shells of automobiles are usually made of polymer materials. In order to achieve a good light transmission effect, the surface of the polymer material needs to be polished and ground. At present, the polishing and grinding methods for the headlight shells are mostly manual grinding with hand-held sanding paper, and the headlight shells are also fixed by manual one-hand support. Therefore, the headlight shells are easily displaced during grinding when manually supported by one hand, resulting in the problem of inaccurate polishing position due to the displacement of the headlight shells. Repeated displacement and grinding can easily cause the outer surface of the headlight shell to be polished unevenly, affecting the polishing effect.

[0003] To this end, both CN218312771U and CN215394501U disclose a device for assisting the polishing of a lamp housing, and both use a clamping plate and a power member for pushing the clamping plate to clamp and fix the lamp housing, such as Figure 1-2 As shown, the clamps in the above patents are all of relatively flat plate-like structures, and the contact with the lamp housing is point contact. Since the shapes of lamp housings vary, the clamps in the above patents cannot provide as many point contacts as possible according to the shapes of the lamp housings themselves, which results in the above auxiliary lamp housing polishing device being unable to effectively fix lamp housings of various shapes.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] A lamp housing polishing workbench, such as Figure 3-6 As shown, it includes: a box body 1, a support plate 2 is provided on the top of the box body 1, a rotating table 3 is rotatably provided on the support plate 2, a plurality of pin holes 31 for matching with the fixing pins 4 are opened on the rotating table 3, and the plurality of pin holes 31 are arranged in an array from the center of the rotating table 3 to its outer edge.

[0026] In this embodiment, the support plate 2 is a tray structure with an edge higher than its bottom, and is installed on the box body 1 by means of snap-fitting, screw fixing, welding, etc. A foot 14 is installed at the four end corners of the bottom of the box body 1. The rotating table 3 is installed at the center of the support plate 2 through the rotating member 25, and can rotate 360 ​​degrees on the support plate 2. The rotating member 25 is a structural component that has a fixed end and a rotating end that can rotate with each other, such as a load-bearing bearing, a turntable, etc. A plurality of pin holes 31 are opened on the top of the rotating table 3 at a certain interval or angle array, and a fixing pin 4 can be inserted into any pin hole 31. When polishing the lamp shell, first place the lamp shell on the rotating table 3, as close to the center as possible, and then insert multiple fixing pins 4 into the pin holes 31 located on the outer edge of the lamp shell accordingly. The number of fixing pins 4 is selected as needed, so as to provide the lamp shell with as many point contacts as possible to achieve effective fixation, thereby overcoming the technical problem that the device for polishing the lamp shell auxiliary in the CN218312771 U patent and the CN215394501 U patent cannot effectively fix lamp shells of various shapes.

[0027] In addition, since the rotating table 3 can rotate freely 360 degrees, the part of the headlight shell that needs to be polished can be rotated to the position most suitable for the operator to polish, thereby facilitating the operator to perform multi-position polishing on the headlight shell and improving the polishing quality.

[0028] Furthermore, the box body 1 is used to contain polishing liquid, and the support plate 2 is provided with a liquid guide hole 21 for guiding the polishing liquid into the interior of the box body 1 .

[0029] like Figure 3-6 As shown, polishing generally requires polishing liquid. In order to facilitate the recovery or recycling of the polishing liquid, a liquid guide hole 21 is opened at the end corner of the support plate 2. The polishing liquid after polishing the lamp shell flows into the interior of the box body 1 through the liquid guide hole 21.

[0030] Furthermore, the support plate 2 is first bent downward at the edge of the liquid guiding hole 21 and then bent toward the center of the liquid guiding hole 21 to form a step groove 22 , and a filter screen 23 is provided on the step groove 22 .

[0031] like Figure 3-6 As shown, using sandpaper to grind and polish the lamp housing generally produces solid residues such as paper scraps or dust. In order to prevent such residues from clogging the liquid guide hole 21, a step groove 22 is provided at the edge of the liquid guide hole 21, and a filter screen 23 is detachably placed on the step groove 22.

[0032] Furthermore, an adjustable hose 24 for discharging the polishing liquid is provided on the support plate 2 .

[0033] like Figure 3 As shown, in order to facilitate the operator to apply an appropriate amount of polishing liquid to the position where the headlight shell needs to be polished, an adjustable hose 24 is installed at the other end corner of the support plate 2. The structure of the adjustable hose 24 is similar to the universal bamboo tube commonly used in the machining field. Its own shape can be adjusted as needed to transport the polishing liquid to the preset position.

[0034] Furthermore, a filter cotton 5 is arranged inside the box body 1 for filtering the polishing liquid after polishing the lamp housing.

[0035] like Figure 5 As shown, in order to further filter the fine dust particles that cannot be filtered by the filter screen 23, a filter cotton 5 is installed inside the box body 1. The filter cotton 5 is fixedly installed below the liquid guide hole 21 with the help of the limiting structure inside the box body 1. The polishing liquid flows through the liquid guide hole 21 and directly flows onto the filter cotton 5. The polishing liquid flows to the bottom of the box body 1 after being filtered by the filter cotton 5. In addition, the filter cotton 5 can also be installed on the side wall of the box body 1, and one end of the hose is connected to the liquid guide hole 21, and the other end of the hose is inserted into the filter cotton 5, so as to achieve secondary filtration of the polishing liquid.

[0036] Furthermore, it also includes: a liquid guiding tube 6 , one end of which is connected to the adjustable hose 24 , and the other end of which is connected to the inside of the box body 1 .

[0037] like Figure 3 As shown, in order to reuse the polishing liquid after secondary filtration, the upper end of the liquid guide tube 6 is connected to the liquid inlet of the adjustable hose 24, and the lower end of the liquid guide tube 6 is connected to the interior of the box 1 through a water pump. The water pump can be installed outside or inside the box 1, preferably inside the box 1.

[0038] Furthermore, a drain valve 11 is provided at the bottom of the box body 1 to facilitate draining the polishing liquid inside the box body 1 out of the box body 1.

[0039] like Figure 3 As shown, in order to facilitate the discharge of the polishing liquid that cannot be recycled out of the box body 1, a manual drain valve 11 is installed at the bottom of the box body 1.

[0040] Furthermore, an inspection opening 12 is provided on the side wall of the box body 1 , and an inspection baffle 13 for blocking the inspection opening 12 is detachably provided on the side wall of the box body 1 .

[0041] like Figure 5 As shown, after long-term use of the utility model, the filter cotton 5 inevitably needs to be replaced. In order to facilitate the replacement of the filter cotton 5 and the maintenance of the water pump installed inside the box body 1, an inspection port 12 is opened on the front side wall of the box body 1, and an inspection baffle 13 is installed at a position of the box body 1 corresponding to the inspection port with screws. The inspection baffle 13 is preferably a transparent plastic plate, and a sealing ring is provided on the side where it is in contact with the box body 1 to prevent leakage of the polishing liquid.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
