Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, a paint spraying and drying device for automobile hubs comprises a base 1, and a clamping part and a drying part which are arranged on the base 1.

As shown in fig. 1-4, the clamping part includes that the symmetry is fixed to be set up on the base two sets of interior grudging posts 2, the symmetry is equipped with two sets of centre gripping hydraulic cylinders on two sets of inner support, the hydraulic stem tip of centre gripping hydraulic cylinder is equipped with the centre gripping body, form the centre gripping station that is used for centre gripping wheel hub between two sets of centre gripping bodies, the centre gripping body includes arc splint 5 made by soft material and the fixed centre gripping connecting rod 18 that is used for butt joint on centre gripping hydraulic cylinder hydraulic stem that sets up in the middle of the arc splint 5 extrados, be equipped with a plurality of elastic contact heads 19 that have the elastic capacity on the intrados of arc splint 5.

Compared with the prior art, the clamping component has the first core concept that the arc-shaped clamping plate is not directly attached to the hub in a surface contact mode, and the overall attachment cannot be guaranteed, but a plurality of elastic contact heads 19 with elasticity are adopted as the mode of contacting with the hub, so that the positions, corresponding to the elastic contact heads 19, of the hub can be basically guaranteed to be tightly extruded by the elastic contact heads 19, the contact overall degree of direct surface contact is not high, and the situation that only a small part of points are actually contacted is generated.

As shown in fig. 3 and 4, a cavity is formed inside the clamping connecting rod 18, a button groove 20 communicated with the cavity is formed above the clamping connecting rod 18, wire holes 21 communicated with the cavity are formed in two sides of the clamping connecting rod 18, an adjusting button 22 is movably arranged in the button groove 20, a plurality of pull wires 23 are fixedly connected to two sides of the arc-shaped clamping plate, the other ends of the pull wires 23 penetrate through the wire holes 21 on the same side and are connected with the adjusting button 22, and the pull wires 23 are in a tensioning state when the adjusting button 22 is located on one side closest to the arc-shaped clamping plate.

Because the size and the dimension of the wheel hub are different, the size of the outer arc surface of the wheel hub is also different, the expanding degree of the arc-shaped clamping plate can be changed, only the adjusting button 22 needs to be pulled to pull the adjusting button backwards, and the containing space formed by the inner arc surface of the arc-shaped clamping plate is changed after the two sides of the arc-shaped clamping plate are pulled backwards under the stretching effect, so that the adjustable capacity is provided to adapt to the wheel hubs with different outer arc radians.

The adjusting button 22 is a switch which can slide by manual operation of people, but can generate a self-locking function immediately after stopping, the principle of the switch generally adopts a magnet, and because the magnetism of the magnet exists, the pressure between the button and the inner wall is very large, and the friction force is also large, so that when people do not apply force by hands, the switch can be stopped at any position under the action of the friction force when the button moves to any position.

As shown in fig. 1 and fig. 2, two sets of outer grudging posts 3 of the fixed setting of stoving part symmetry on base 1, grudging post 2 is located between two sets of outer grudging posts 3 in two sets of, the symmetry is rotated and is equipped with pivot 6 on two sets of outer grudging posts 3, fixedly in the pivot 6 being equipped with riser 7, the fixed diaphragm 8 that is equipped with in tip edge of the skew pivot 6 of riser 7, be equipped with drying assembly 9 between two sets of diaphragm 8, pivot 6 realizes rotating through angle beat structure, pivot 6 rotates back drying assembly 9 and moves towards the centre gripping station with the angle of difference.

Compared with the prior art, the second core concept of the drying component is to abandon the connection of the rotating motor to the hub, because the hub is thick and heavy, it is difficult to change the orientation of the hub by the rotating motor, and even if the hub is connected with a hydraulic rod besides the rotating motor, the clamping reliability of the hub is reduced by the driving sources of the two connections.

Therefore, the thought is changed through the design, the position and the direction of the drying assembly 9 are changed through the angle deflection structure, but in the angle deflection process, the drying assembly 9 always faces to the direction of the axis of the rotating shaft 6 due to the existence of the vertical plate 7 and the transverse plate 8, and as long as the axis of the rotating shaft 6 penetrates through the clamping station, the direction of the drying assembly 9 also always faces to the hub in the clamping station, so that the hub can be dried in a large range.

The angle deflection structure comprises an outer rod 10 which is fixedly arranged at the end part of one rotating shaft 6 and is provided with an inner hole, an inner rod 11 which is arranged in the inner hole of the outer rod 10 in a sliding mode, a sliding block 12 which is arranged at the end part of one end, deviating from the outer rod 10, of the inner rod 11 in a rotating mode through a connecting shaft, a limiting rod 13 which is fixedly arranged on the base 1 and a linear driving element 14 which is arranged on the base 1, wherein a limiting hole is formed in the sliding block 12 and is connected with the limiting rod 13 through the limiting hole to complete straight limiting, and the linear driving element 14 is used for driving the sliding block 12 to linearly slide back and forth in the direction of the limiting rod 13.

As shown in fig. 1, during operation, the linear driving element 14 is used to drive the sliding block 12 to slide back and forth in a linear direction, and then the inner rod 11 extends or shortens relative to the outer rod 10 along with the movement of the sliding block 12, but because the inner rod 11 is rotatably connected with the sliding block 12, the orientations of the outer rod 10 and the inner rod 11 are also changed, and because the drying assembly 9 is fixed relative to the outer rod 10, the drying assembly 9 is adjusted in angle toward the hub in the station direction.

The type of linear drive element 14 can take many forms. For example, the linear driving hydraulic cylinder is fixedly arranged on the base 1, and a hydraulic rod of the linear driving hydraulic cylinder is fixedly connected with the slide block 12. For example, the linear driving mechanism comprises a linear driving motor fixedly arranged on the base 1 and a screw rod rotatably arranged on the base 1, wherein a threaded hole is formed in the sliding block 12, the threaded hole is in butt joint with the screw rod, and the linear driving motor is used for driving the screw rod to rotate.

The rotating shaft 6 and a hydraulic rod of the clamping hydraulic cylinder 4 are collinear, so that the direction of the drying component 9 towards the station is always the hub center, and the drying dispersibility is optimal.

The drying component 9 comprises a tray frame, a fan component 15 and a heating component 16, wherein the fan component 15 and the heating component 16 are arranged on the tray frame, the fan component 15 comprises a fan motor and fan blades arranged at the output end of the fan motor, and the heating component 16 comprises a heating wire mesh plate.

The fan assembly 15 provides rapid air circulation to provide a blowing and drying function, and the heating assembly 16 heats air to provide a processing and drying function.

The base 1 is also provided with a collecting tank 17 for collecting the dripping paint.
