DETAILED DESCRIPTION

[0039] The present application provides a multi-axis support spraying positioning device as shown in Figures 1-14 the figure, which comprises an operating table 1, and the top of the operating table 1 is fixedly installed with a support 26, and the support 26 is provided with spraying equipment 27, which comprises a nozzle, a conveying pipe and other structures, and is used for spraying treatment on the positioned Christmas ball 28, and the spraying equipment 27 and its working principle are both common existing technologies, and will not be described here.

[0040] It is considered that in the prior art, when the ball 28 is partially sprayed, the paper sticking method is usually used for shielding, but since the spherical surface is a three-dimensional curved surface, the paper edge is easy to wrinkle and curl, and the manual alignment is slow, in order to improve the spraying efficiency, the operating table 1 is provided with outer shaft sleeves 2 on both sides of the top, the axes of the two outer shaft sleeves 2 are collinearly distributed, the inside of the outer shaft sleeve 2 is slidably provided with a middle shaft sleeve 3, and a first elastic telescopic rod 5 is arranged between the outer shaft sleeve 2 and the middle shaft sleeve 3, the fixed end of the first elastic telescopic rod 5 is fixedly connected to the inner wall of the outer shaft sleeve 2, and the telescopic end of the first elastic telescopic rod 5 is fixedly connected to the end of the middle shaft sleeve 3.

[0041] In actual use, a protective cover (refer to Figure 1 ) is arranged outside the outer shaft sleeve 2, and the outer shaft sleeve 2 is protected by the protective cover.

[0042] The outer shaft sleeve 2 is made of a material not affected by magnetic force, such as hard plastic.

[0043] The inner wall of the outer sleeve 2 is provided with a mounting groove, and the electromagnetic iron 17 is fixedly installed in the mounting groove. The middle sleeve 3 is assembled by two parts, including a part not affected by magnetic force (made of hard plastic, etc.) and a part affected by magnetic force 29 (made of stainless steel affected by magnetic force, etc.). The part affected by magnetic force 29 is small in size and is fixedly installed on the part not affected by magnetic force in a fixed inlaying manner (see Figure 14 ), and is distributed opposite to the electromagnetic iron 17.

[0044] When the electromagnetic iron 17 is powered to generate magnetic force, the part affected by magnetic force 29 is adsorbed and fixed, so that the middle sleeve 3 is adsorbed and fixed, and the outer sleeve 2 and the middle sleeve 3 form a whole. When the electromagnetic iron 17 loses magnetic force after being powered off, the outer sleeve 2 and the middle sleeve 3 can slide relative to each other, and the first elastic expansion rod 5 provides elastic support force to avoid random sliding.

[0045] The inner wall of the middle sleeve 3 is provided with a mounting groove, and the electromagnetic iron 17 is fixedly installed in the mounting groove. The middle sleeve 3 and the inner sleeve 4 are provided with the second elastic expansion rod 6, the fixed end of the second elastic expansion rod 6 is fixedly connected to the inner wall of the middle sleeve 3, and the expansion end of the second elastic expansion rod 6 is fixedly connected to the end of the inner sleeve 4.

[0046] The inner wall of the middle sleeve 3 is provided with a mounting groove, and the electromagnetic iron 17 is fixedly installed in the mounting groove. The middle sleeve 3 and the inner sleeve 4 are provided with the second elastic expansion rod 6, the fixed end of the second elastic expansion rod 6 is fixedly connected to the inner wall of the middle sleeve 3, and the expansion end of the second elastic expansion rod 6 is fixedly connected to the end of the inner sleeve 4. Figure 14 ), and is distributed opposite to the electromagnetic iron 17.

[0047] When the electromagnetic iron 17 is powered to generate magnetic force, the part affected by magnetic force 29 is adsorbed and fixed, so that the middle sleeve 3 is adsorbed and fixed, and the outer sleeve 2 and the middle sleeve 3 form a whole. When the electromagnetic iron 17 loses magnetic force after being powered off, the outer sleeve 2 and the middle sleeve 3 can slide relative to each other, and the first elastic expansion rod 5 provides elastic support force to avoid random sliding.

[0048] In actual use, the electromagnetic iron 17 on the outer sleeve 2 and the electromagnetic iron 17 on the middle sleeve 3 are staggered and do not affect each other.

[0049] The above-mentioned electromagnetic iron 17 is connected to the power supply of the factory.

[0050] The outer sleeve 2, the middle sleeve 3 and the inner sleeve 4 form a three-layer inner and outer sleeve sliding structure. In actual use, multiple middle sleeves 3 and second elastic expansion rods 6 can be arranged, and the diameters of the multiple middle sleeves 3 are different, so as to form more layers of inner and outer sleeve sliding structures, which can be adjusted according to specific use conditions.

[0051] In addition, the inner wall of the outer sleeve 2, the inner and outer walls of the middle sleeve 3 and the inner and outer walls of the inner sleeve 4 are smooth, so that the outer sleeve 2 and the middle sleeve 3 and the middle sleeve 3 and the inner sleeve 4 can be gaplessly matched, facilitating subsequent cleaning.

[0052] The inner sleeve 4 is provided with a shaft tube 8, and the inner sleeve 4 and the shaft tube 8 are concentrically arranged. The lengths of the shaft tube 8, the outer sleeve 2, the middle sleeve 3 and the inner sleeve 4 gradually decrease. The inner diameter of the inner sleeve 4 is greater than the outer diameter of the shaft tube 8. The two shaft tubes 8 are rotatably provided with shaft discs 7 abutting against the spherical body 28 at one end close to each other. The shaft discs 7 can be slidably recovered to the inside of the inner sleeve 4. The two shaft discs 7 are provided with grooves on the sides close to each other, matching the shape of the spherical body 28.

[0053] When positioning, the spherical body 28 is clamped and positioned between the two shaft discs 7.

[0054] The shaft disc 7 and the shaft tube 8 have a certain damping feeling. When the spherical body 28 is clamped and positioned between the two shaft discs 7, the shaft disc 7 and the shaft tube 8 will not randomly rotate relative to each other without external force (such as the hand of an operator holding it).

[0055] In order to realize the movement and rotation of the structures such as the outer sleeve 2, the middle sleeve 3 and the inner sleeve 4, fixed plates 18 are fixedly connected at both ends of the top of the operation table 1. The fixed plates 18 are provided with sliding holes. The shaft tubes 8 are arranged in the sliding holes. The shaft tubes 8 can rotate and slide in the sliding holes. Wear-resistant pads or other structures can be arranged in the sliding holes during use to reduce wear.

[0056] The side of the fixed plate 18 close to the outer sleeve 2 is provided with a vertical plate 19. The vertical plate 19 is rotatably arranged on the outer sleeve 2. The shaft tube 8 can rotate on the vertical plate 19. The shaft tube 8 and the vertical plate 19 can synchronously move along the axial direction of the shaft tube 8.

[0057] The first electric push rod 23 is fixedly connected to the fixed plate 18. The vertical plate 19 is fixedly connected to the extension end of the first electric push rod 23. The first electric push rod 23 drives the vertical plate 19 and the shaft tube 8 to move along the axial direction of the shaft tube 8. When the extension end of the first electric push rod 23 is controlled to extend, the vertical plate 19 is driven to move away from the fixed plate 18. When the extension end of the first electric push rod 23 is controlled to be recovered, the vertical plate 19 is driven to move towards the fixed plate 18.

[0058] The vertical plate 19 is provided with a driving assembly for driving the shaft tube 8 to rotate. The driving assembly includes a first gear 20, a motor 21 and a second gear 22. The motor 21 is fixedly connected to the vertical plate 19. The first gear 20 is fixedly connected to the driving shaft of the motor 21. The second gear 22 is fixedly connected to the shaft tube 8. The first gear 20 is meshingly connected with the second gear 22. Specifically, the motor 21 drives the first gear 20 to rotate. Since the first gear 20 is meshingly connected with the second gear 22, the second gear 22 drives the shaft tube 8 to rotate.

[0059] A second electric push rod 24 is fixedly connected to the vertical plate 19. A circular sleeve 25 is fixedly connected to the telescopic end of the second electric push rod 24. The circular sleeve 25 is rotatably mounted on the corresponding outer bushing 2. The outer bushing 2 can move synchronously with the circular sleeve 25, and the outer bushing 2 and the circular sleeve 25 can rotate relative to each other. The second electric push rod 24 drives the outer bushing 2 and the circular sleeve 25 to move. When the telescopic end of the second electric push rod 24 is extended, the outer bushing 2 and the circular sleeve 25 move away from the fixed plate 18. When the telescopic end of the first electric push rod 23 is retracted, the outer bushing 2 and the circular sleeve 25 move towards the fixed plate 18.

[0060] The first electric actuator 23, the second electric actuator 24, the motor 21, etc. are all connected to the factory's power supply.

[0061] When not in use, the outer bushing 2, the middle bushing 3, and the inner bushing 4 are flush with the ends away from the fixing plate 18 (refer to...). Figure 12 ).

[0062] The electromagnet 17 is controlled according to the area to be sprayed on the sphere 28. For example, the edge of the local spraying on the sphere 28 corresponds to the edge of the inner wall of the central sleeve 3 (refer to...). Figure 5 As shown in the diagram), the electromagnet 17 at the outer bushing 2 is energized, so that the outer bushing 2 and the middle bushing 3 form a whole; while the electromagnet 17 at the middle bushing 3 is de-energized, and the middle bushing 3 and the inner bushing 4 can slide relative to each other.

[0063] First, control the retraction ends of the two second electric push rods 24 to retract, thereby increasing the distance between the two outer bushings 2. Then, control the retraction ends of the two first electric push rods 23 to retract, thereby increasing the distance between the two shaft discs 7.

[0064] The operator places the ball 28 between the two shaft disks 7 and simultaneously controls the extension and retraction ends of the two first electric push rods 23 to extend, so that the ball 28 is clamped and positioned between the two shaft disks 7.

[0065] Next, the telescopic ends of the two second electric push rods 24 are extended synchronously, driving the outer bushing 2 and the circular sleeve 25 to move towards the ball 28. The shaft disk 7 enters the interior of the inner bushing 4, and the ball 28 first abuts against the edge of the inner wall of the inner bushing 4. Since the middle bushing 3 and the inner bushing 4 can slide relative to each other, the inner bushing 4 slides towards the circular sleeve 25 inside the middle bushing 3 due to the limiting effect of the ball 28. Subsequently, the ball 28 abuts against the edge of the inner wall of the middle bushing 3 (refer to...). Figure 5 As shown in the figure, since the outer bushing 2 and the middle bushing 3 have been integrated, the extension and retraction ends of the two second electric push rods 24 are controlled to stop extending.

[0066] At this time, the outer sleeve 2, the middle sleeve 3 and the like form a shielding structure, quickly shielding the part that does not need to be sprayed; and the outer sleeve 2, the middle sleeve 3 and the like are flush at the end away from the fixed plate 18 (see Figure 12 ), without affecting the spraying, and the ball 28 is clamped and positioned.

[0067] If the outer diameter of the outer sleeve 2 is greater than the diameter of the ball 28, the outer sleeve 2 plays a role of a fence on both sides of the ball 28, preventing the paint from splashing everywhere.

[0068] In addition, the shaft disc 7, the inner sleeve 4 and the middle sleeve 3 all abut on the ball 28, and the multiple shafts support each other to ensure the stability of clamping and positioning.

[0069] In actual use, the extension distance of the first electric push rod 23 and the second electric push rod 24 can be controlled according to the size of the ball 28, so as to avoid excessive extrusion of the ball 28, and the extension distance can be adjusted by an operator.

[0070] Local spraying is performed by using the spraying device 27, and the effect of the ball 28 after spraying is shown in Figure 13 , and the shaded part is the spraying area.

[0071] If the range of local spraying of the ball 28 becomes smaller, the inner wall edge of the outer sleeve 2 can be made to abut on the ball 28; if the range of local spraying of the ball 28 becomes larger, the inner wall edge of the inner sleeve 4 can be made to abut on the ball 28, that is, according to the specific processing needs, the outer sleeve 2, the middle sleeve 3 and the inner sleeve 4 are selectively made to abut on the outside of the ball 28, so as to meet different local spraying ranges.

[0072] The size of the shielding structure is flexibly controlled by the electromagnet 17, the first electric push rod 23 and the second electric push rod 24, without affecting the spraying, preventing the paint from splashing everywhere, and improving the applicability of the device.

[0073] The positions of the outer sleeve 2, the middle sleeve 3 and the inner sleeve 4 away from the fixed plate 18 and the like can be provided with but are not limited to a fluorinated silicon dioxide-fluorosilicon resin composite coating, so that the paint is not easy to adhere, similar to the "lotus effect", which is convenient for subsequent operators to clean; or paper can be pasted on the positions of the outer sleeve 2, the middle sleeve 3 and the inner sleeve 4 away from the fixed plate 18, the outer wall of the outer sleeve 2 and the like before spraying, to prevent the paint from adhering. Compared with the three-dimensional curved surface of the ball 28, these positions are planar or annular, the curved surface operation is converted into planar or annular operation, the paper protection is more convenient, and a single piece of paper can be used for a long time.

[0074] The application synchronously realizes the functions of rapid shielding and positioning, and does not wrinkle or warp, is fast in alignment, meets different local spraying ranges, and guarantees the stability of clamping and positioning and improves the use efficiency of the multi-axis support spraying positioning device.

[0075] In consideration of the fact that the outer part of the sphere 28 is prone to retaining dust and other impurities for a long time, in order to realize dust removal of the sphere 28, a support block 9 is fixedly connected to the outer wall of the shaft pipe 8, a round rod 10 is fixedly connected to the support block 9, and a swing pipe 12 is rotatably arranged on the round rod 10. The swing pipe 12 is communicated with a connecting pipe 16, one end of the connecting pipe 16 away from the swing pipe 12 is communicated with the shaft pipe 8, the connecting pipe 16 uses a flexible hose, and the angle of the swing pipe 12 can be adjusted without affecting the swing pipe 12. The shaft pipe 8 is connected and matched with the gas suction pipeline of the factory through a rotary joint and a hose.

[0076] A plurality of through holes 13 are arranged on the swing pipe 12, and the plurality of through holes 13 are uniformly distributed along the length direction of the swing pipe 12.

[0077] A torsional spring 11 is sleeved on the round rod 10, one end of the torsional spring 11 is fixedly connected to the round rod 10, and the other end of the torsional spring 11 is fixedly connected to the swing pipe 12. When the swing pipe 12 is staggered with the outer shaft sleeve 2, the middle shaft sleeve 3 and the inner shaft sleeve 4, the swing pipe 12 is in an open state under the elastic supporting force of the torsional spring 11, that is, one end of the swing pipe 12 away from the round rod 10 swings away from the axis direction of the shaft pipe 8 (see Figure 12 , and the through holes 13 are directed to the position to be sprayed on the sphere 28.

[0078] In actual use, after the sphere 28 is clamped and positioned between the two shaft discs 7, the swing pipe 12 is in a staggered state with the outer shaft sleeve 2, the middle shaft sleeve 3 and the inner shaft sleeve 4 (see Figure 12 ), and one end of the swing pipe 12 away from the shaft pipe 8 is inclined towards the sphere 28, so as to ensure stable recovery when the sphere 28 is pressed by the inner shaft sleeve 4.

[0079] The impurities on the outer part of the sphere 28 are sucked by the shaft pipe 8, the connecting pipe 16, the swing pipe 12 and the through holes 13, and the operator can control the sphere 28 to be stationary during the process. The position where the operator contacts the sphere 28 is a non-spraying area, or the operation can be performed by a mechanical arm. The driving assembly drives the swing pipe 12 to rotate around the axis of the shaft pipe 8 through the shaft pipe 8, so as to perform rotary cleaning and clean the position to be sprayed on the sphere 28 in all directions, so as to ensure the quality of subsequent spraying.

[0080] After the cleaning is completed, the extension end of the second electric push rod 24 is controlled to extend, the outer shaft sleeve 2 and the round sleeve 25 are driven to move towards the sphere 28, the inner wall edge of the inner shaft sleeve 4 first abuts against the swing pipe 12, so that one end of the swing pipe 12 away from the round rod 10 swings away from the axis direction of the shaft pipe 8 (seeFigure 5 、 Figure 6 The shaft disc 7 enters the interior of the inner sleeve 4, and then the swing pipe 12 enters the interior of the inner sleeve 4.

[0081] Compared with the prior art of setting an additional dust collection device (a vacuum cleaner, etc.), the present application uses the movement of the inner sleeve 4 to realize the swinging extension and recovery of the swing pipe 12, which is convenient to operate and does not require manual movement or additional power components, thereby saving the trouble of wiring; when cleaning, the swing pipe 12 is automatically close to the sphere 28 in an open state and rotates to clean, thereby ensuring the coverage range; the recovery is designed to be hidden, thereby avoiding the influence of the sprayed paint.

[0082] The position where the swing pipe 12 is in contact with the edge of the inner wall of the inner sleeve 4 is provided with a wear-resistant pad, etc., to reduce wear.

[0083] In addition, the shaft pipe 8 can also be connected and matched with the gas delivery pipeline of the factory through a hose, etc., and after the spraying is completed, the sphere 28 can be blown by the shaft pipe 8, the connecting pipe 16, the swing pipe 12, and the through hole 13 to achieve the effect of rapid air drying, which can be adjusted according to the specific use.

[0084] In order to realize flexible operation, a circular block 15 is fixedly connected to the end of the swing pipe 12 away from the shaft pipe 8, and a plurality of arc grooves 14 for clamping the circular block 15 are formed in the inner wall of the inner sleeve 4.

[0085] Specifically, when the outer sleeve 2, the middle sleeve 3, and the inner sleeve 4 move axially along the shaft pipe 8, the circular block 15 can slide in the corresponding arc groove 14, which does not affect the extension and recovery of the swing pipe 12 and also does not affect the movement of the outer sleeve 2, the middle sleeve 3, and the inner sleeve 4 relative to the shaft pipe 8.

[0086] When the sphere 28 is clamped and positioned by the shaft disc 7, the inner sleeve 4, the middle sleeve 3, etc., the circular block 15 and the swing pipe 12 are recovered to the interior of the inner sleeve 4, at which time the circular block 15 can be directly clamped in one of the arc grooves 14; or it first abuts against the inner wall of the inner sleeve 4, and then the driving assembly drives the shaft pipe 8, the swing pipe 12, and the circular block 15 to rotate, and the circular block 15 can also be clamped in one of the arc grooves 14 later, thereby stably driving the outer sleeve 2, the middle sleeve 3, and the inner sleeve 4 to rotate, since the sphere 28 is not subjected to external force such as hand holding by an operator during this process, the sphere 28 can be synchronously rotated, which is convenient for uniform and omnidirectional spraying by the spraying device 27.

[0087] In addition, the swing pipe 12, the circular block 15, etc. are made of high-strength materials such as stainless steel, etc., to ensure the use strength.

[0088] By setting the arc groove 14, round block 15 and other structures, a single drive assembly can drive the shaft tube 8 to rotate alone, and also drive the shaft disc 7, inner shaft sleeve 4, middle shaft sleeve 3, ball 28 and other structures to rotate, without affecting the relative movement of the outer shaft sleeve 2, middle shaft sleeve 3, inner shaft sleeve 4 and shaft tube 8, facilitating positioning, dust removal, spraying and other operations.
