Description

Technical Field

[0001] The utility model belongs to the technical field of wheel hub surface treatment, and particularly relates to a wheel hub spraying and sandblasting treatment device. Background Art

[0002] Sandblasting is usually required during wheel hub processing to obtain a certain degree of cleanliness and different roughness on the surface of the workpiece, thereby improving the mechanical properties of the workpiece surface and thus improving the fatigue resistance of the workpiece, such as the sandblasting device for wheel hub processing in announcement number CN214603825U.

[0003] The current processing device needs to use an external feeding rack or other structure to feed or discharge the material. When the feeding rack contacts the sandblasting equipment, if excessive force is applied, it will cause a collision, which will not only damage the equipment but also cause the placed wheel hub to be misplaced. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a wheel hub spraying and sandblasting processing device to solve the problem that the existing processing device proposed in the above background technology is prone to damage to the equipment and misplacement of the wheel hub feeding due to excessive pushing during feeding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wheel hub spraying and sandblasting device, comprising a body, a side opening for a material inlet and outlet, a protective door rotatably connected to the side opening for a material inlet and outlet, a side opening for a placement groove, and the placement groove being directly below the protective door; further comprising a buffer assembly placed in the placement groove, wherein the buffer assembly comprises a protective member and a return member; the protective member is partially placed in the placement groove and partially protrudes from the outside of the placement groove, and the protruding portion contacts the feed rack to achieve buffering, and the return member is placed inside the protective member to ensure that the protective member has a partial structure that can protrude from the placement groove, and contacts the feed rack through this protruding portion to achieve a buffering effect.

[0006] Preferably, the protective member is an airbag, and part of the airbag protrudes to the outside of the placement groove; the bottom end of the airbag is connected to multiple air pipes, and a through hole for the air pipe to pass through is opened on the inner bottom end surface of the placement groove. When the airbag contacts the feed rack, the airbag will be pressed by the feed rack and the gas inside the airbag will be discharged from the air pipe. Since the diameter and number of the air pipes are fixed, the amount of discharged gas has a maximum value, that is, by using the airbag as a buffer, the speed at which the feed rack and the machine body come into contact can be reduced to avoid damage caused by collision.

[0007] Preferably, the restoring member includes a spring placed inside the airbag, with two ends of the spring respectively pressed against two sides of the inner wall of the airbag, thereby partially protruding the airbag to the outside of the placement groove.

[0008] Preferably, the rear surface of the airbag is further adhered with double-sided tape, and the double-sided tape is adhered to the inner wall of the placement groove, thereby achieving the installation of the airbag and preventing the airbag from detaching from the placement groove.

[0009] Preferably, a discharge port is provided on the bottom end surface of the body, and a water tank is connected to the end of the discharge port. Liquid is injected into the water tank, and metal impurities and other impurities in the exhaust gas are adsorbed through the water tank to avoid direct discharge and affect subsequent processing.

[0010] Preferably, an exhaust pipe is connected to the side of the water tank, and the connection area between the exhaust pipe and the water tank is higher than the horizontal plane of the liquid in the water tank to prevent the liquid from being discharged directly from the exhaust pipe.

[0011] Preferably, a display screen is further provided on the front surface of the body, and supporting feet are installed at the four corners of the bottom end surface of the body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed buffer component can provide buffer protection between the feed rack and the equipment during feeding, avoiding the impact caused by too fast contact between the two. While reducing damage, it can also ensure that the wheel hub on the feed rack will not be significantly misaligned, ensuring normal feeding in the later stage, and improving the shortcomings of the existing structure in use.
