Description

Technical Field

[0002] With the rapid development of the automobile industry, the automobile frame is an important part of the automobile, and its surface treatment process is increasingly valued. Spraying is a key step in the surface treatment of the frame, and its quality directly affects the overall performance and appearance of the car. When using the vehicle, users will inevitably encounter scratches on the frame or paint peeling. When the surface paint of the frame peels off, users usually choose to send it to the repair shop for paint spraying repair. The existing paint spraying usually disassembles the frame to be sprayed with paint and places it on the spray rack for spraying, or exposes the entire frame area to be sprayed and covers the non-spraying area. No matter which method is used, it needs to be carried out in a certain space. The sprayed paint is easy to pollute the surrounding environment. If it is manually operated, uneven spraying may occur, and the air drying speed of the paint after spraying is long. The present invention provides a vehicle frame surface spraying device, which can spray paint on four frame components at the same time. During the spraying process, the entire spraying environment is approximately closed, which greatly reduces the pollution of the paint to the surrounding operating environment and protects the health of the operators.

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] 1. The surface painting device of the automobile frame has two cylindrical pins fixedly connected to the rotating gear. The two cylindrical pins rotate in a circle along with the rotating gear. The two cylindrical pins are sleeved in two sleeve pins. When the cylindrical pins rotate, the sleeve pins sleeved on the outside of the cylindrical pins are driven to rotate. The sleeve pins are fixedly connected to the first panel and drive the first panel to rotate. The first panel and the second panel are fixedly connected through the two ends of the first arc-shaped long plate. When the first panel rotates, the first arc-shaped long plate and the second panel connected thereto are driven to rotate, that is, the entire rotating barrel rotates in a circle. The adjustable sleeve pins are adjusted by the tightening ring. The arc device is connected with the rotating barrel to form an approximately closed whole. When the rotating barrel rotates in a circle, the adjustable arc device also rotates in a circle. The automobile frame connected to the adjustable arc device performs a circular motion along with the adjustable arc device. Through the spraying of the high-pressure nozzle and the coordination of the circular rotation of the adjustable arc device, the paint sprayed from the high-pressure nozzle is evenly sprayed onto the surface of the automobile frame on the adjustable arc device. Through the rotation of the adjustable arc device, the paint is more evenly sprayed, so that four automobile frames can be evenly sprayed at one time, thereby improving the paint spraying efficiency.

[0019] 2. This automobile frame surface spraying device, with the help of the rotation of the spraying mechanism, drives the rotating ball to roll in a circle on the inclined inclined circular plate, thereby converting the circular motion of the rotating ball on the inclined inclined circular plate into the reciprocating movement of the second panel on the horizontal line, that is, driving the horizontal reciprocating motion of the rotating barrel. Through the horizontal reciprocating motion of the rotating barrel and the spraying of the high-pressure nozzle, it is ensured that both ends of the automobile frame in the spraying mechanism can also be sprayed with paint, avoiding the occurrence of spraying dead angles and improving the spraying quality.

[0020] 3. The automobile frame surface painting device connects the connection hole A with the receiving part through bolt A, connects the connection hole C with the receiving part through bolt C, connects the bolt B with hole B and then with hole E, and bends the bent plate to lock the entire clamp ring, thereby ensuring the stability and sealing of the adjustable arc device and the rotating barrel, avoiding the paint from polluting the surrounding operating environment when the automobile frame is subsequently sprayed with paint, and protecting the health of the operator.

[0021] 4. The automobile frame surface spraying device drives the rotation of the spraying mechanism in the open state through the connecting column, and the rotation of the spraying mechanism drives the surrounding air flow to air-dry the paint on the automobile frame that has been sprayed, thereby accelerating the paint drying speed.

[0022] 5. This automobile frame surface painting device drives the second arc-shaped long plate to rotate by rotation, and also drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the latch teeth and the self-locking ring. The self-locking ring is in a groove arranged on the periphery of the latch teeth, and the latch teeth are connected to the self-locking ring through a spring. When the latch teeth rotate, the latch teeth pop out from the groove and engage with the ratchet-shaped tooth grooves inside the gear plate, thereby locking the rotating shaft. After rotating to a suitable position, the self-locking ratchets at both ends of the rotating shaft are locked, which is convenient for the subsequent operation of placing the automobile frame on the second arc-shaped long plate and convenient for operators to fix the position of the automobile frame.

[0053] Working principle:

[0054] In the first step, when the device is not in use, the wrench 316 is in a locked state. The operator first removes the bolt B3163, and the connection hole E3162 and the bent plate 3161 fixedly connected to the connection hole E3162 are separated from the connection hole B3133, and the locking state of the entire wrench 316 is released. Then the bolt A312 and the bolt C317 are taken out, and the first half-arc arm 313 sleeved with the bolt A312 and the second half-arc arm 314 sleeved with the bolt C317 are separated from the receiving part 311, and the clamp ring 3163 is locked. The locking state of the spray chamber 32 is released. At this time, the operator rotates the auxiliary handle 3225, and the auxiliary handle 3225 is fixedly connected to the second arc-shaped long plate 3221. When the auxiliary handle 3225 rotates, the second arc-shaped long plate 3221 connected to the auxiliary handle 3225 is driven. The interior of the second arc-shaped long plate 3221 is fixedly connected with a rotating shaft 3222. Self-locking ratchet wheels 3223 are provided at both ends of the self-locking ratchet wheel 3223. The self-locking ring 32232 in the self-locking ratchet wheel 3223 is engaged with the card The teeth 32233 are fixedly connected to the two ends of the rotating shaft 3222, and the gear plate 32231 of the self-locking ratchet 3223 is fixedly connected to the rotating barrel 321. Therefore, when the operator drives the second arc-shaped long plate 3221 to rotate by turning the auxiliary handle 3225, the rotation of the rotating shaft 3222 is also driven. The rotation of the rotating shaft 3222 drives the rotation of the latch teeth 32233 and the self-locking ring 32232. The self-locking ring 32232 is in a groove arranged on the periphery of the latch teeth 32233, and the latch teeth 32233 are connected to the rotating barrel 321. It is connected to the self-locking ring 32232 through a spring. When the latch tooth 32233 rotates, the latch tooth 32233 pops out from the groove and engages with the ratchet-shaped tooth groove inside the gear plate 32231, thereby locking the rotating shaft 3222. When the operator rotates the auxiliary handle 3225 to a suitable position, the self-locking ratchets 3223 at both ends of the rotating shaft 3222 are locked, which facilitates the subsequent operation of placing the automobile frame on the second arc-shaped long plate 3221, and is convenient for the operator to fix the position of the automobile frame.

[0055] In the second step, after the first step, the operator places the automobile frame that needs to be surface-painted on the second arc-shaped long plate 3221, and pays attention to the outer surface of the frame facing the paint storage bin 16, and clamps the automobile frame with the clamping hands 3224 set on the inner surface of the second arc-shaped long plate 3221 to increase the stability of the automobile frame on the second arc-shaped long plate 3221 during the subsequent painting work to prevent the automobile frame from falling off the second arc-shaped long plate 3221. When the automobile frame is fixed, the auxiliary handle 3225 is turned again to return the second arc-shaped long plate 3221 to the initial closed position, and the connecting hole A3131 is connected to the receiving part 311 by the bolt A312, and the connecting hole C3141 is connected to the receiving part 311 by the bolt C317, and the connecting hole B3133 is connected to the connecting hole E3162 by the bolt B3163. Then, the operator Fig.10 The bent plate 3161 is bent in the direction shown to lock the entire clamp ring 31, thereby ensuring the stability and sealing of the adjustable arc device 322 and the rotating barrel 321, avoiding the paint from polluting the surrounding operating environment when the automobile frame is subsequently sprayed with paint, and protecting the health of the operator.

[0056] In the third step, the paint storage bin 16 is connected to a high-pressure paint spraying device. The high-pressure paint spraying device connected to the paint storage bin 16 is turned on, and the paint enters the paint storage bin 16 and begins to be sprayed outward through the high-pressure nozzle 17. The spraying range of the high-pressure nozzle 17 is to spread around the paint storage bin 16 as the center. At this time, the operator turns on the motor connected to the connecting column 22, and the connecting column 22 begins to rotate. The connecting column 22 is fixedly connected to the driving gear 23. The rotation of the connecting column 22 drives the rotation of the driving gear 23, and the driving gear 23 is meshed with the rotating gear 12. When When the driving gear 23 rotates, it drives the rotating gear 12 meshing therewith to rotate. The rotating gear 12 is fixedly connected with two cylindrical pins 13. The two cylindrical pins 13 rotate in a circle along with the rotating gear 12. The two cylindrical pins 13 are sleeved in two sleeve pins 3212. When the cylindrical pins 13 rotate, the sleeve pins 3212 sleeved on the outside of the cylindrical pins 13 are driven to rotate. The sleeve pins 3212 are fixedly connected to the first panel 3211. Therefore, when the sleeve pins 3212 rotate, the first panel 3211 fixedly connected thereto is The first curved long plate 3213 also rotates, and the two ends of the first curved long plate 3213 are fixedly connected to the first panel 3211 and the second panel 3214. Therefore, when the first panel 3211 rotates, the first curved long plate 3213 and the second panel 3214 connected thereto will be driven to rotate, that is, the entire rotating barrel 321 rotates in a circle. In the previous step, the adjustable curved device 322 is connected to the rotating barrel 321 through the tight hoop ring 31 to form an approximately closed whole. Therefore, when the rotating barrel 321 rotates in a circle, the adjustable curved device The device 322 also performs circular rotation, and the automobile frame connected to the adjustable arc device 322 performs circular motion along with the adjustable arc device 322. Through the spraying of the high-pressure nozzle 17 and the coordination of the circular rotation of the adjustable arc device 322, the paint sprayed from the high-pressure nozzle 17 is evenly sprayed onto the surface of the automobile frame on the adjustable arc device 322. Through the rotation of the adjustable arc device 322, the paint is more evenly sprayed, so that four automobile frames can be evenly sprayed at one time, thereby improving the paint spraying efficiency.

[0057] In the fourth step, when the spraying mechanism 3 in the previous step starts to rotate, the protective sleeve 32151 is fixedly connected to the second panel 3214, the threaded column 32152 is protected in the protective sleeve 32151, the threaded column 32152 is fixedly connected with the hexagonal column 32153, the hexagonal column 32153 is connected with the rotating ball 32154, the rotating ball 32154 is brought into contact with one side of the inclined circular plate 41, and the other side of the inclined circular plate 41 is brought into contact with one end of the angle adjustment screw 56, and the angle adjustment screw 56 is rotated. The tilt degree of the tilted circular plate 41 is controlled, and with the help of the rotation of the spraying mechanism 3, the rotating ball 32154 is driven to roll in a circle on the tilted tilted circular plate 41, thereby converting the circular motion of the rotating ball 32154 on the tilted tilted circular plate 41 into a reciprocating motion of the second panel 3214 on the horizontal line, that is, the horizontal reciprocating motion of the rotating barrel 321 is driven. Through the horizontal reciprocating motion of the rotating barrel 321 and the spraying of the high-pressure nozzle 17, it is ensured that both ends of the automobile frame in the spraying mechanism 3 can also be sprayed with paint, avoiding the occurrence of spraying dead angles and improving the spraying quality.

[0058] In the fifth step, when the automobile frame is sprayed, the motor connected to the connecting column 22 and the high-pressure spraying equipment connected to the high-pressure nozzle 17 are turned off, and the operator disassembles the clamp ring 31 again. After the disassembly is completed, the auxiliary handle 3225 is turned again to rotate the second arc-shaped long plate 3221 to a suitable position and then locked by the self-locking ratchet 3223. At this time, the motor connected to the connecting column 22 is turned on again, and the connecting column 22 drives the rotation of the spray mechanism 3 in the open state, as shown in FIG. Fig.15 As shown, the rotation of the spraying mechanism 3 drives the surrounding air flow to dry the paint on the automobile frame that has been sprayed, thereby accelerating the drying speed of the paint. After the paint is completely dried, the operator opens the clamp 3224 to take out the automobile frame.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
