[0003] Common bumpers are generally made of polypropylene plastics and are usually injection-molded.
[0004] After the existing bumper is injection-molded into a finished product, in order to improve the surface corrosion resistance, anti-corrosion paint is generally sprayed on the surface of the bumper semi-finished product. Therefore, a spraying fixture for the surface of the bumper semi-finished product is required.
[0005] At present, for the existing spraying fixture for the surface of the bumper semi-finished product, after clamping the bumper semi-finished product, the spraying comprehensiveness for the bumper semi-finished product is relatively weak. In addition, during the spraying process of the existing spraying fixture for the surface of the bumper semi-finished product, the paint that is missed and dripped will directly drip onto the ground, resulting in waste of resources.
[0006] The above problems are widespread and urgently need to be improved. Content of the Utility Model

[0010] Furthermore, the front end of the fixture box is of an open structure and the back end is of a closed structure. The clamping cylinder and the chuck are in a group, and there are two groups in total that are symmetrically arranged left and right.
[0011] Further, a connecting pipe is provided between the liquid storage tank and the high-pressure pump, and the top view cross-section of the main infusion pipe is a T-shaped structure.
[0012] Further, the liquid spraying pipe and the high-pressure nozzle are a group, and there are three groups arranged horizontally in total. The liquid spraying pipe vertically penetrates the jig box, and the high-pressure nozzle is a downward diffusing cover structure.
[0013] Further, the liquid guiding surface is inclined five degrees towards the liquid extraction pipe part, and the corrosion-resistant and smooth layer is uniformly arranged along the upper end surface of the liquid guiding surface.

Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0026] Refer to Figures 1-5 , a new - type bumper spraying fixture, including a fixture bottom plate 1, a fixture box 2 is provided on the fixture bottom plate 1, a box cover 21 and a magnetic strip 22 are provided on the fixture box 2, a liquid suction pump 4 and a pre - storage liquid tank 11 are provided on the fixture bottom plate 1, a drain pipe 12 is provided on the pre - storage liquid tank 11, a clamping cylinder 3 is provided on the fixture box 2, a rotating motor 31 is provided on the telescopic rod of the clamping cylinder 3, a chuck 32 is provided on the rotating motor 31, a liquid storage tank 6 and a high - pressure pump 7 are provided on the fixture box 2, a main infusion pipe 71 is connected to the high - pressure pump 7, a spraying pipe 72 is connected to the main infusion pipe 71, a high - pressure nozzle 73 is provided on the spraying pipe 72, a liquid guide surface 5 is provided in the fixture box 2, a corrosion - resistant and smooth layer 51 is provided on the liquid guide surface 5, the liquid suction pump 4 is connected with a liquid extraction pipe 42, and both the high - pressure pump 7 and the liquid suction pump 4 are common paint high - pressure suction pump bodies, which are prior arts.
[0027] Specifically, the front end of the fixture box 2 is of an open - type structure and the back end is of a closed - type structure, preventing the paint from high - pressure spraying from spraying out from the back end of the fixture box 2.
[0028] The clamping cylinder 3 and the chuck 32 are a set, and there are two sets in total that are symmetric left and right. The chuck 3 is arranged on the motor shaft of the rotating motor 31 to effectively and stably clamp the semi - finished bumper, thereby ensuring the subsequent uniform axial rotation and high - pressure spraying effect.
[0029] Furthermore, a connecting pipe 61 is provided between the liquid storage tank 6 and the high - pressure pump 7, and the top - view cross - section of the main infusion pipe 71 is of a T - shaped structure, realizing the uniform and rapid diversion and delivery of the paint to the three spraying pipes 72.
[0030] Furthermore, the liquid spraying pipe 72 and the high-pressure nozzle 73 are in a group, and there are three groups arranged horizontally in total. The liquid spraying pipe 72 vertically passes through the jig box 2 to achieve the high-pressure spraying effect of three groups of paints synchronously.
[0031] The high-pressure nozzle 73 is a downward-diffusing hood structure, which further increases the effective area of the high-pressure spraying of the paint downward.
[0032] More specifically, the liquid guiding surface 5 is inclined by five degrees towards the liquid suction pipe 42, so that the dripping paint can be quickly guided and concentrated in the right direction along the inclined liquid guiding surface 5, which is convenient to be pumped away.
[0033] The corrosion-resistant and smooth layer 51 is uniformly arranged along the upper surface of the liquid guiding surface 5. The corrosion-resistant and smooth layer 51 is a PTFE polytetrafluoroethylene coating, with a flat and smooth surface, and is corrosion-resistant and durable, which further improves the flow efficiency of the paint to the right.
[0034] Generally speaking, there is an infusion pipe 41 between the liquid suction pump 4 and the pre-storage liquid tank 11. The liquid suction pipe 42 is in an overall L-shaped structure, and there is a gap between the surface of the liquid suction pipe 42 and the corrosion-resistant and smooth layer 51 to prevent the suction part of the liquid suction pipe 42 from being blocked and ensure the suction effect.
[0035] Finally, the box cover 21 is rotatably arranged on the jig box 2. The box cover 21 is rotatably connected to the jig box 2 through a preset rotating shaft. When spraying, the box cover 21 can be rotated to cover it. At this time, the magnetic strip 22 will stably magnetically adsorb the box cover 21 made of metal material to prevent the paint from spraying out during spraying.
[0036] The magnetic strip 22 is in an overall rectangular strip structure and is arranged at the front end of the jig box 2. The magnetic strip 22 is made of artificial magnet material and can stably magnetically adsorb the box cover 21 made of metal material.
[0037] Working method: Place the semi-finished bumper in the central part of the two clamping heads 32, then start the clamping cylinder 3 to drive the two clamping heads 32 to move closer to each other at a uniform speed. After the two clamping heads 32 firmly clamp the semi-finished bumper, stop the clamping cylinder 3, and then start the rotating motor 31 and the high-pressure pump 7. The rotating motor 31 will drive the clamped semi-finished bumper to rotate axially at a uniform speed. At the same time, the started high-pressure pump 7 will evenly supply the anti-corrosion paint stored in the liquid storage tank 6 to the three liquid spraying pipes 72 through the main infusion pipe 71 and spray it downward in a full range through the high-pressure nozzles 73 to achieve full-range high-pressure spraying of the axially rotating semi-finished bumper, thereby overall improving the comprehensiveness of the spraying of the semi-finished bumper.
[0038] In addition, when performing high-pressure paint spraying, the liquid suction pump 4 can be started. At this time, a strong suction force will be formed at the liquid extraction pipe 42. Some of the anti-corrosion paint sprayed by high-pressure paint spraying will be accidentally dropped on the bottom of the jig box 2. These paints will flow quickly in the right direction along the inclined liquid guide surface 5 with a corrosion-resistant smooth layer 51, and then will be completely sucked away by the liquid extraction pipe 42 and conveyed through the liquid infusion pipe 41 to be stored in the pre-storage liquid tank 11. Later, the preset valve on the drain pipe 12 can be opened to discharge the paint, and then it can be filtered and purified to form clean paint for recycling, avoiding the waste of resources caused by the paint directly dropping on the ground.
[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
