Description

Technical Field

[0001] The invention relates to the technical field of wheel hub paint spraying, and in particular to a wheel hub paint spraying device with high adaptability and a method thereof. Background Art

[0002] The wheel hub is an important part of the wheels of vehicles such as cars, motorcycles, and bicycles. It is located on the inside of the tire and fits tightly with the tire. It is used to support the tire and fix it on the axle of the vehicle. During the production process of the wheel hub, in order to increase the aesthetics and corrosion resistance of the wheel hub, it is necessary to spray various protective paints and color paints on the wheel hub. Generally, the wheel hub needs to be removed from the wheel and moved to the spray processing area, and the wheel hub is sprayed through a series of spray processing processes.

[0003] According to a vehicle wheel hub surface spraying device with patent publication number CN118558507A, the working platform is provided with a clamping part and a spraying part, the clamping part is used for clamping the wheel hub, the clamping part is rotatably arranged on the working platform, and the spraying part comprises: an adjustable spraying part, the interior of which is divided into a plurality of spraying slots, a one-way valve is arranged between adjacent spraying slots, each spraying slot is provided with a discharge channel and a feed nozzle, and the end of the discharge channel is connected to the nozzle; a rotating rod, the end of which is provided with a connecting part, the other end of the connecting part is slidably connected to the outside of the adjustable spraying part, a paint tube is arranged inside the rotating rod, and a slidingly connected connecting nozzle is arranged at the end of the paint tube for detachable installation on the corresponding feed nozzle; a supporting frame is used to support and drive the rotating rod to rotate.

[0004] The above-mentioned device cooperates with the clamping part and the spraying part, uses the clamping part to limit the two sides of the wheel hub, and then cooperates with the spraying part to rotate to spray the wheel hub. However, due to this clamping placement method, the wheel hub needs to be supported or suspended on the clamping part during the spraying process, so that some areas of the wheel hub will be blocked, which makes it difficult for these areas to be effectively sprayed. In addition, the clamping part may also directly contact the paint surface, thereby causing secondary spraying, which not only increases the time and cost of spraying, but also affects the spraying quality and efficiency. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a wheel hub paint spraying equipment and method with high adaptability, which solves the problem of paint not being sprayed in place due to placement obstruction by enhancing the overall adaptability of the equipment.

The middle part of the slider is rotatably penetrated by the mounting rod, the bottom end of the mounting rod is provided with a support plate, and six mechanical claws for assisting in grasping the wheel hub are hingedly provided on the support plate, and electric push rods II with telescopic ends facing downwards are symmetrically provided on both sides of the mounting rod, and two triangular plates displaced up and down are slidably penetrated on the mounting rod, and a corner of the two triangular plates close to the electric push rod II is respectively connected to the telescopic end of the corresponding side, and a connecting rod is provided at the bottom of each corner of the triangular plate, and the connecting rod is slidably and rotatably connected to the adjacent mechanical claws to drive the mechanical claws to realize opening or closing operation.

[0007] Preferably, the spray assembly includes a spray window, a spray gun and a linear motor. The spray window is arranged on the rear side of the shell, and the linear motor is arranged on the front side of the spray window. A spray gun for wheel hub painting is arranged on the moving part of the linear motor. The spray gun is semi-annular so as to fit the wheel hub to form an arc-shaped paint trajectory.

[0008] Preferably, a straight groove is provided on the spray window for left and right operation directions, and the rear interface of the spray gun passes through the straight groove to form a sliding fit.

[0009] Preferably, it also includes a convex plate and a convex block. The top of the mounting rod is provided with a convex block, and a convex plate with protrusions matching the convex block is provided between the two sides of the top of the electric slide rail to push the mounting rod to rotate through the contact of the concave and convex surfaces.

[0010] Preferably, a conveying mechanism is also included, which includes a bracket, a baffle and an electric roller. Brackets are arranged on the left and right sides of the shell, and baffles are symmetrically and slidingly arranged on both sides of the bracket. Multiple electric rollers are arranged at intervals on the opposite sides of the two baffles to promote the transportation of materials in and out of the wheel hub.

[0011] Preferably, the conveying mechanism also includes a motor and a bidirectional screw. The motor is installed on one side of the bracket, and the bidirectional screw is connected to the output shaft of the motor. The threads at both ends of the bidirectional screw respectively penetrate the baffle plate on the same side and form a threaded fit.

[0012] Preferably, a stop block is also included, and the opposite ends of the bracket are each provided with a stop block for limiting the wheel hub.

[0013] A method for using a wheel hub paint spraying device with high adaptability comprises the following steps:

[0014] S1. First, start the motor, which drives the bidirectional screw to rotate, thereby driving the shielding plates on both sides to move, so as to adjust the distance between them. Then, place the wheel hub to be painted between the electric rollers on the left. When the wheel hub moves to the end, it will contact and be blocked by the stop block.

[0015] S2. The electric slide rail drives the slider and the grabbing mechanism to slide to the left as a whole. As the slider slides, the mechanical claw approaches the position of the wheel hub that needs to be painted, and then the electric push rod I is started to drive the mobile frame and its upper parts to move up, so that the mechanical claw is higher than the highest point of the wheel hub, so as to grab the wheel hub. When the mechanical claw is placed above the wheel hub, the telescopic ends of the electric push rods II on both sides extend, thereby driving the corresponding mechanical claws to retract and pass through the middle position of the wheel hub. Then the telescopic end of the electric push rod II on one side is shortened, so that the corresponding three mechanical claws are opened to support the wheel hub. Then the slider can be driven to move right, and the electric push rod I moves down to reset the original height. During this process, the spray gun will be driven to move left by the linear motor, so that the wheel hub and the spray gun are on the same horizontal line to ensure the synchronization of the two, and then the painting operation can be started;

[0016] S3. As the slider moves to the right, the spray gun is driven by the linear motor to move right synchronously with the operation of the wheel hub for spraying, and when the slider moves to the right, the convex block contacts the convex plate, thereby driving the wheel hub to rotate and spray paint. At this time, the wheel hub is supported by three mechanical claws on one side, and the supporting part of the wheel hub is blocked and cannot be sprayed. When the wheel hub moves to the middle of the electric slide rail, the three mechanical claws on the other side are opened for support, and then the corresponding electric push rod II is driven to retract the three mechanical claws previously supporting, and then replace them with another three mechanical claws for support, so as to expose the blocked area, and then cooperate with the arc-shaped painting trajectory of the spray gun so that the blocked part of the wheel hub can also be evenly sprayed;

[0017] S4. The wheel hub after painting will finally move to the right between the electric rollers on the right. According to step S2, the up and down driving operation of the electric push rod I will be repeated. Then the electric push rod II will be extended to drive the material discharge. The wheel hub after painting will be placed between the electric rollers on the right and transported out.

[0018] The present invention overcomes the shortcomings of the prior art and can achieve the following beneficial effects:

[0019] 1. The present invention uses the setting of the grasping mechanism and the electric push rod II to drive the mechanical claws on the corresponding side to open or retract, so as to support and fix the center position of the wheel hub, avoid the obstruction problem caused by clamping and placement, and at the same time, the mechanical claws can flexibly switch the support points to cope with the spraying of the wheel hub, and then cooperate with the spray gun with an arc-shaped spraying trajectory to complete the full-scale painting of the wheel hub. The adaptability is improved and the spraying of the wheel hub can be flexibly handled to achieve efficient operation.

[0020] 2. The present invention uses the characteristics of concave-convex contact through the cooperation of the convex plate and the convex block to enable the wheel hub to rotate during the spraying process, thereby achieving an all-round spraying effect.

[0021] 3. The present invention realizes an integrated process of hub spraying by providing a conveying mechanism, thereby making the material collection, spraying and discharging processes more coherent and improving the efficiency of hub production. BRIEF DESCRIPTION OF THE DRAWINGS

The telescopic ends of the electric push rods Ⅰ2 pass through the top of the shell 1, and the movable frame 3 is connected between the telescopic ends of the two electric push rods Ⅰ2 on the same side. The movable frame 3 is attached to the outer wall of the same side of the shell 1 and can slide along it. The movable frame 3 is driven by the electric push rod Ⅰ2 to perform vertical movement up and down, so that the spraying operation can be performed at different heights so as to In the spraying operation of the wheel hub 101, an electric slide rail 4 located inside the housing 1 is arranged between the two moving frames 3, and a slider 41 is slidably arranged on the electric slide rail 4, which can provide a platform for the slider 41 to carry its sliding operation, so as to realize the lateral left and right movement of the slider 41 along the electric slide rail 4, and a grabbing mechanism 6 for grabbing the wheel hub 101 for spraying paint is arranged in the middle of the slider 41, and the grabbing mechanism 6 can cooperate with the wheel hub 101 to grab and adjust the angle, and compared with the traditional placement spraying method, the wheel hub 101 can be accurately sprayed in multiple directions to ensure the paint spraying in all directions, and a spraying component for spraying the wheel hub 101 is arranged on the rear side of the housing 1;The grabbing mechanism 6 also includes a mounting rod 61, a support plate 62, a mechanical claw 63, an electric push rod II 64, a triangular plate 65 and a connecting rod 66. The middle part of the slider 41 is rotatably provided with a mounting rod 61, and the bottom end of the mounting rod 61 is provided with a support plate 62. The support plate 62 is a hexagonal base, which is a mounting carrier adapted for the grabbing component. Six mechanical claws 63 for assisting in grabbing the wheel hub 101 are hingedly provided on the support plate 62, so that the mechanical claws 63 can rotate freely on the support plate 62, so that the wheel hub The gripping of 101 is more flexible, and electric push rods II 64 with telescopic ends facing downward are symmetrically arranged on the front and rear sides of the mounting rod 61. Two vertically offset triangular plates 65 are slidably penetrated on the mounting rod 61. One corner of the two triangular plates 65 close to the electric push rod II 64 is respectively connected to the telescopic end of the corresponding side. The two electric push rods II 64 can drive the correspondingly connected triangular plates 65 to slide up and down on the mounting rod 61 accordingly, and the bottom of each corner of the triangular plate 65 is provided with a connecting rod 66. The connecting rod 66 6 is connected to the adjacent mechanical claws 63 by sliding and rotating, so as to pull the mechanical claws 63 to realize opening or closing operation. When the telescopic end of the electric push rod II 64 is extended, the corresponding triangular plate 65 is driven to move downward, and the connected mechanical claws 63 are pulled by the connecting rod 66, so that the two form a certain degree of rotation and sliding operation, and then the connecting rod 66 pulls the mechanical claws 63 to approach the support plate 62 and close to achieve the closing effect. On the contrary, when the telescopic end of the electric push rod II 64 is shortened, the mechanical claws 63 will be in an open state. By controlling the triangular plates 65 on different sides, the three mechanical claws 63 on both sides are in corresponding opening and closing states, so that the adaptability of the equipment is improved, and the wheel hub 101 can be flexibly handled. Grabbing; when the mechanical claws 63 on both sides form opposite operations, the support part can be replaced, so that the area blocked by the support part can be exposed, and spraying is performed through the spraying assembly to avoid the problem of inadequate spraying of the wheel hub 101 due to the blocking caused by placement, thereby ensuring that the wheel hub 101 can be sprayed in all directions. ;

[0035] like Figure 1-Figure 4 As shown, the spraying assembly includes a spraying window 5, a spray gun 52 and a linear motor 521. The spraying window 5 is arranged on the rear side of the housing 1, and the linear motor 521 is arranged in the spraying window 5. A spray gun 52 for spraying paint on the wheel hub 101 is arranged on the moving part of the linear motor 521. The spray gun 52 is semi-annular to fit the shape of the wheel hub 101 to form an arc-shaped paint trajectory, so that the spraying of the wheel hub 101 is more in place, and a straight groove 51 for the left and right operating directions is opened on the spraying window 5. The rear side interface of the spray gun 52 passes through the straight groove 51 and forms a sliding fit, thereby limiting the operation of the spray gun 52 and facilitating the material connection of the spray gun 52.

[0036] like Figure 6 and Figure 7As shown, it also includes a convex plate 42 and a convex block 43. The top of the mounting rod 61 is provided with a convex block 43, and the convex block 43 is triangular in shape. A convex plate 42 with a protrusion matched with the protrusion 43 is provided between the left and right sides of the top of the electric slide rail 4. The protrusion on the convex plate 42 is matched with the protrusion 43 and is arranged at intervals. The contact between the concave and convex surfaces of the two can push the mounting rod 61 to rotate, so that the wheel hub 101 can rotate and be sprayed circumferentially, so that the paint spraying is more comprehensive.

[0037] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, a conveying mechanism 7 is also included, and the conveying mechanism 7 includes a bracket 71, a baffle plate 72 and an electric roller 73. The brackets 71 are arranged on the left and right sides of the shell 1, and the baffle plates 72 are symmetrically slidably arranged on the front and rear sides of the bracket 71. The electric rollers 73 are arranged at intervals on the opposite sides of the two baffle plates 72 to promote the transportation of the wheel hub 101 in and out, so that the production of the wheel hub 101 can be streamlined.

[0038] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the conveying mechanism 7 also includes a motor 74 and a bidirectional screw rod 75. The motor 74 is installed on one side of the bracket 71. The output shaft of the motor 74 is connected to the bidirectional screw rod 75 that passes through two baffle plates 72 on the same side. The two baffle plates 72 are respectively threadedly connected to the two ends of the bidirectional screw rod 75, so that the two baffle plates 72 are pushed to achieve relative movement through threaded cooperation, so as to adjust the distance between the two, so that the wheel hub 101 fits better during transportation.

[0039] like Figure 8 and Fig. 9 As shown, a stop block 76 is also included. The opposite end of the bracket 71 is provided with a stop block 76 for limiting the wheel hub 101 to prevent the wheel hub 101 from being offset or unnecessarily moved during the conveying process, thereby ensuring the accuracy of the position when discharging the material to facilitate the gripping of the mechanical claw 63.

[0040] Based on the above-mentioned wheel hub paint spraying equipment with high adaptability, a method for using the wheel hub paint spraying equipment with high adaptability includes the following steps:

[0041] S1. First, start the motor 74, which drives the bidirectional screw 75 to rotate, thereby driving the shielding plates 72 on both sides to move, so as to adjust the distance between the two, and then place the wheel hub 101 to be painted between the electric roller wheels 73 on the left, and when the wheel hub 101 moves to the end, it will contact and be stopped by the stop block 76;

[0042] S2, the electric slide rail 4 drives the slider 41 and the grabbing mechanism 6 to slide to the left as a whole. As the slider 41 slides, the mechanical claw 63 approaches the position of the wheel hub 101 that needs to be painted, and then the electric push rod Ⅰ2 is started to drive the moving frame 3 and its upper components to move up, so that the mechanical claw 63 is higher than the highest point of the wheel hub 101, so as to grab the wheel hub 101. When the mechanical claw 63 is placed above the wheel hub 101, the telescopic ends of the electric push rods Ⅱ64 on both sides are extended, thereby driving the corresponding mechanical claws 63 to retract and pass through the middle position of the wheel hub 101. Then the telescopic end of the electric push rod Ⅱ64 on one side is shortened, so that the corresponding three mechanical claws 63 are opened to support the wheel hub 101. Then the slider 41 can be driven to move right, and the electric push rod Ⅰ2 moves down to reset the original height. In this process, the spray gun 52 will be driven by the linear motor 521 to move left, so that the wheel hub 101 and the spray gun 52 are on the same horizontal line to ensure the synchronization of the two, and then the painting operation can be started;

[0043] S3. As the slider 41 moves to the right, the spray gun 52 is driven by the linear motor 521 to move right synchronously with the operation of the wheel hub 101 for spraying, and when the slider 41 moves to the right, the convex block 43 contacts the convex plate 42, thereby pushing the wheel hub 101 to rotate and make it rotate to spray paint. At this time, the wheel hub 101 is supported by three mechanical claws 63 on one side, and the supporting part of the wheel hub 101 is blocked and cannot be sprayed. When the wheel hub 101 moves to the middle of the electric slide rail 4, the three mechanical claws 63 on the other side are opened for support, and then the corresponding electric push rod II 64 is driven to retract the three previously supported mechanical claws 63, thereby replacing them with another three mechanical claws 63 for support, so as to expose the blocked area, and then cooperate with the arc-shaped painting trajectory of the spray gun 52 so that the blocked part of the wheel hub 101 can also be evenly sprayed with paint;

[0044] S4, the wheel hub 101 after painting will finally move to the right between the right electric rollers 73, and the electric push rod I2 will be driven up and down according to step S2, and then the electric push rod II 64 will be extended to drive the discharge, and the wheel hub 101 after painting will be placed between the right electric rollers 73 and transported out.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.

Spraying is performed, and when the wheel hub (101) moves to the middle of the electric slide rail (4), the three mechanical claws (63) on the other side are opened for support, and then the corresponding electric push rod II (64) is driven to retract the three mechanical claws (63) previously supporting, thereby replacing them with another three mechanical claws (63) for support, thereby exposing the blocked area, and then cooperating with the arc-shaped painting trajectory of the spray gun (52) so that the blocked part of the wheel hub (101) can also be evenly sprayed with paint; S4, the wheel hub (101) after painting will finally move to the right between the right electric rollers (73), and the electric push rod I (2) will be driven up and down according to step S2, and then the electric push rod II (64) will be extended to drive the material discharge, and the wheel hub (101) after painting will be placed between the right electric rollers (73) and transported out.
