Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub spraying, in particular to an automatic rotating spraying device for manufacturing automobile wheel hubs. Background Technique

[0002] In the process of manufacturing automobile wheel hubs, spraying the automobile wheel hubs is a necessary process and a process with relatively high requirements. For automobile wheel hubs, the whole needs to be evenly sprayed to perform rust prevention treatment on the automobile wheel hubs, thereby extending the service life of the wheel hubs and improving the aesthetics of the wheel hubs.

[0003] Before spraying the wheel hubs, it is generally necessary to clean the spraying area of the wheel hubs. This process is generally completed manually or with manual assistance. Subsequently, the cleaned wheel hubs are transported to the spraying area, and the wheel hubs are fixed on the rotating rod, and the outer surface of the wheel hubs is sprayed with a spray gun. After the wheel hubs are cleaned, they need to be transported to the spraying area again. During the transportation of the wheel hubs, dust floating in the air is easily adhered to the outer surface of the wheel hubs again. As a result, raised dust spots are likely to appear on the surface of the wheel hubs during spraying, affecting the aesthetics of the wheel hubs. After spraying, more time needs to be spent on grinding the dust spot areas, thereby reducing the operation efficiency.

[0004] Based on this, it is necessary to design an automatic rotating spraying device for manufacturing automobile wheel hubs to avoid the defect that the outer surface of the wheel hubs is re-adhered with dust after being cleaned. Summary of the Utility Model

[0005] The technical solution of the utility model is: an automatic rotating spraying device for manufacturing automobile wheel hubs, which includes a bottom plate, a cross plate, a first cylinder, a connecting rod, a crank block, an inverted T-shaped rod, an L-shaped connecting block, a rotating assembly, a fixing assembly and a spraying assembly. A cross plate is installed on the top of the bottom plate. A V-shaped groove is opened on the cross plate. An inverted T-shaped rod is slidably connected in the V-shaped groove. The upper part of the inverted T-shaped rod is connected with a crank block. The end of the crank block far from the connection with the inverted T-shaped rod is fixedly connected with an L-shaped connecting block through a connecting rod. The L-shaped connecting block is rotatably connected with the movable end of the piston rod of the first cylinder installed on the bottom plate. The upper part of the L-shaped connecting block is provided with a rotating assembly for driving the wheel hub body to rotate and a fixing assembly for squeezing and fixing the wheel hub body. On both sides of the bottom plate with the cross plate as the center, a cleaning assembly for cleaning the wheel hub body and a spraying assembly for spraying the wheel hub body are symmetrically arranged.

[0006] As a further preferred solution, the rotating assembly includes a commutation motor, an installation cylinder and a top plate. The upper end of the L-shaped connecting block is rotatably connected with an installation cylinder. A commutation motor for driving the installation cylinder to rotate is installed on the upper part of the L-shaped connecting block. A top plate surrounding the installation cylinder is detachably installed on the side of the installation cylinder facing away from the L-shaped connecting block. The top plate is connected with the fixing assembly.

[0007] As a further preferred solution, the fixing component includes a connecting sleeve, an arc-shaped pressing plate and a spring. A connecting sleeve is connected to the side of the top plate facing away from the mounting cylinder. The outer wall of the circumference of the connecting sleeve is movably connected with arc-shaped pressing plates at uniform intervals. A spring is arranged between the arc-shaped pressing plate and the inner wall of the connecting sleeve.

[0008] As a further preferred solution, an extrusion component for driving the top plate to eject outwards to fix the hub body is arranged in the mounting cylinder. The extrusion component includes a cylinder two and an extrusion cone. A cylinder two is installed in the mounting cylinder. The movable end of the piston rod of the cylinder two is connected with an extrusion cone. The extrusion cone slides through the top plate and extends into the connecting sleeve to provide an extrusion force for the top plate.

[0009] As a further preferred solution, the spraying component includes a vertical plate, a cylinder three, a shielding frame, a paint delivery pipe and a spray gun.

No less than one spray gun is installed on the inner circumferential wall of the upper part of one side of the shielding frame and on the circular inner wall connected with the piston rod of the cylinder three. The spray gun is communicated with the paint delivery pipe installed on the shielding frame. A cleaning component for cleaning the hub body is arranged on the other side of the shielding frame.

[0010] As a further preferred solution, the cleaning component includes a circular cleaning block and an arc-shaped cleaning block. The arc-shaped cleaning block and the circular cleaning block are adhesively connected to the inner circumferential wall of the upper part of the other side of the shielding frame and the circular inner wall connected with the piston rod of the cylinder three 16 correspondingly.

[0011] As a further preferred solution, the lower side of the annular part of the shielding frame is provided with a notch.

[0012] As a further preferred solution, collecting frames are symmetrically arranged on both sides of the top of the bottom plate. The collecting frames are arranged directly below the shielding frame.

[0013] The utility model has the following advantages: Through the pushing and pulling movement of the piston rod of the cylinder one on the connecting rod, the connecting rod drives the crank block to drive the inverted T-shaped rod to move along the V-shaped groove. Thus, the inverted T-shaped rod slides into the rectangular area of the V-shaped groove and then slides out of the rectangular area of the V-shaped groove. During this process, the crank block rotates 180 degrees under the driving of the inverted T-shaped rod and the connecting rod, so as to rotate the hub body by 180 degrees, and then turn over the hub that has completed the cleaning operation and convey it to the spraying area for spraying. This process has the advantages of high-efficiency conveying and simple operation, thereby avoiding dust from adhering to the outer surface of the hub body and reducing the generation of dust spots during spraying.

[0027] As Figure 1 , Figure 6 and Figure 7 shown, the spraying component includes a vertical plate 15, a cylinder three 16, a shielding frame 17, a paint delivery pipe 18, and a spray gun 19. Vertical plates 15 are symmetrically arranged on both sides of the top of the bottom plate 1. Cylinder three 16 is installed on the upper part of each vertical plate 15.

During the process of the inverted T-shaped rod 6 moving to the right and gradually sliding into the rectangular area of the V-shaped groove 201, the connecting rod 4, under the thrust of the piston rod of the first cylinder 3 during its extension movement, pushes the crank block 5 to rotate counterclockwise by 90 degrees with the connection point between the inverted T-shaped rod 6 and the bottom of the V-shaped groove 201 as the center. The crank block 5 drives the L-shaped connecting block and the components installed on the L-shaped connecting block to rotate counterclockwise by 90 degrees. At this time, the hub body 100 rotates counterclockwise by 90 degrees synchronously; as the piston rod of the first cylinder 3 continues to extend, the connecting rod 4 drives the crank block 5 to pull the inverted T-shaped rod 6 out of the rectangular area of the V-shaped groove 201. During this process, the connecting rod 4, under the thrust of the piston rod of the first cylinder 3 during its extension movement, pulls the crank block 5 to rotate counterclockwise by 90 degrees again, thereby driving the L-shaped connecting block and the components installed on the L-shaped connecting block to rotate counterclockwise by 90 degrees again, thus rotating the hub body counterclockwise by 180 degrees, thereby achieving the function of turning over the hub body 100; at this time, the paint is sprayed onto the outer wall of the hub body 100 through the spray gun 19 on the right side, realizing the efficient spraying function of the hub body 100; through the above operations, the functions of effectively fixing, cleaning, and automatically rotating and spraying hub bodies 100 of different specifications can be achieved.
