Description

Technical Field

[0001] The present invention relates to the field of paint spraying technology, and in particular to a paint spraying device for intelligent mechanical manufacturing and processing. Background Art

[0002] Bearings are commonly used in mechanical manufacturing and are generally composed of four parts: inner ring, cage, roller and outer ring. The rollers are in rolling contact with the inner ring and outer ring at the same time. The cage is used to constrain multiple rollers to prevent the rollers from circumferential movement. Before the bearing is put into use, it needs to be sprayed with oil-based paint for lubrication and rust prevention.

[0003] An invention patent with application number 202310545913.0 discloses a spray device for bearing rust prevention, and specifically discloses the technical solution that "the present invention drives the outer ring of the bearing to rotate so that the rust inhibitor can better penetrate into the interior of the bearing, thereby spraying rust prevention on the ball inside the bearing."

[0004] Although the application has the function of spraying the roller inside the bearing, when the outer ring rotates and drives the roller through friction, the roller that is not well lubricated has the risk of getting stuck with the cage. At this time, the contact surface between the roller and the outer ring continues to slip, the roller does not rotate, and only the partial outer surface of the roller that is not covered by the cage, inner ring, and outer ring can be sprayed with paint. The existing technology has a certain room for improvement in the automatic spraying function of the bearing roller part. Summary of the invention

An axial traction groove 707 is provided in the axial traction ring 706. A traction protrusion 7051 is fixedly arranged on the traction rod 705, and the traction protrusion 7051 is slidably engaged in the axial traction groove 707.

[0035] like Figure 1 to Figure 11 As shown, the axial traction concave rail 707 includes an upper avoidance flat rail 7071, a lower contact flat rail 7072 and a connecting arc rail 7073. The upper avoidance flat rail 7071 is located above the lower contact flat rail 7072. There are two upper avoidance flat rails 7071 in a circumferential array, and there are two lower contact flat rails 7072 in a circumferential array. The two upper avoidance flat rails 7071 and the two lower contact flat rails 7072 are staggered. There are four connecting arc rails 7073, and the four connecting arc rails 7073 are respectively connected and arranged between adjacent upper avoidance flat rails 7071 and lower contact flat rails 7072. When the traction protrusion 7051 is located in the upper avoidance flat rail 7071, the bottom of the traction rod 705 is suspended above the retaining frame of the bearing. When the traction protrusion 7051 is located in the lower contact flat rail 7072, the bottom of the traction rod 705 is pressed against the roller of the bearing.

[0036] like Figure 1 to Figure 11 As shown, the collaborative monitoring unit 8 includes a sealed shell 801, an encoder 802, a sealed cover 803, a connecting rod 804 and an attachment block 805. The sealed shell 801 is fixed on the workbench 2, the sealed shell 801 is coaxial with the retaining frame positioning seat 601, the sealed cover 803 is rotatably arranged above the sealed shell 801, the encoder 802 is fixed in the workbench 2 and is located in the sealed shell 801, the encoder 802 is coaxial with the retaining frame positioning seat 601, the rotating end of the encoder 802 is fixedly connected to the sealed cover 803, the connecting rod 804 is fixed at the top of the sealed cover 803, the attachment block 805 is fixed at the top of the connecting rod 804, and the attachment block 805 is fitted on the bottom of the inner ring of the bearing.

[0037] like Figure 1 to Figure 11As shown, a base 1 is provided below the workbench 2, a top plate 3 is provided above the workbench 2, a pillar 9 is fixedly provided between the base 1 and the top plate 3, the workbench 2 and the pillar 9 are slidably connected, a main lifting electric push rod 10 is fixedly provided on the base 1, and the top end of the main lifting electric push rod 10 is fixedly connected to the workbench 2.

[0038] like Figure 1 to Figure 11 As shown, an upper indexing motor 11 is fixedly provided below the top plate 3 , an output end of the upper indexing motor 11 is fixedly connected to the main frame 4 , and the upper indexing motor 11 is coaxial with the retaining frame positioning seat 601 .

[0039] like Figure 1 to Figure 11 As shown, the spray gun group 5 includes an outer spray gun 501, an inner spray gun 502 and a middle spray gun 503. The outer spray gun 501, the inner spray gun 502 and the middle spray gun 503 are all fixedly connected with the main frame 4. Paint hoses (not shown) are fixedly arranged on the tops of the outer spray guns 501, the inner spray guns 502 and the middle spray guns 503. The outer spray gun 501 is used for spraying the outer side of the outer ring of the bearing, the inner spray gun 502 is used for spraying the inner layer of the inner ring of the bearing, and the middle spray gun 503 is used for spraying the inner side of the outer ring, the roller and the outer side of the inner ring of the bearing.

[0040] When in use, the bearing to be sprayed with oily paint is placed on the retainer positioning seat 601, and the main lifting electric push rod 10 drives the workbench 2 and the bearing above to rise, so that the locking column 605 is pressed tightly against the roller of the bearing.

[0041] The oily paint is pumped from an external paint container to the paint hose and the spray gun assembly 5, and the outer spray gun 501, the inner spray gun 502 and the middle spray gun 503 are used to lubricate and spray the bearings for rust prevention.

[0042] During the spraying process, the outer spray gun 501 and the inner spray gun 502 are kept closed first, and the middle spray gun 503 sprays alone. The outer drive motor 602 drives the drive wheel 603 to rotate continuously. The drive wheel 603 drives the outer ring of the bearing to rotate continuously through friction. Among the rollers of the bearing, only the group of rollers closest to the middle spray gun 503 is not pressed by the locking column 605, and rotates under the friction of the outer ring of the bearing, and drives the inner ring of the bearing to rotate. The outer ring, rollers, and inner ring of the bearing rotate around their respective axes, and the rotating rollers cooperate with the stationary middle spray gun 503 to evenly spray the bearing rollers.

[0043] During the spraying process of the bearing roller, the attachment block 805 is closely attached to the bottom of the inner ring of the bearing (the attachment connection method of the attachment block 805 and the bottom of the inner ring of the bearing is a prior art, which can be achieved by conventional means such as magnetic connection, adhesive bonding or suction cup suction), and moves synchronously with the inner ring of the bearing, and transmits the rotation amplitude of the inner ring of the bearing to the encoder 802 through the connecting rod 804 and the sealing cover 803. Under the condition that the outer drive motor 602 and the driving wheel 603 rotate the outer ring of the bearing at a uniform speed, the rotation amount received at the encoder 802 should be proportional to the running time of the outer drive motor 602, and indicate the normal transmission status of the outer ring, roller and inner ring.

[0044] If there is a jamming phenomenon between the roller and the cage that is not well lubricated, that is, the roller cannot rotate normally to transmit power and fully receive paint spraying, then under the condition that the external drive motor 602 and the drive wheel 603 drive the outer ring of the bearing to rotate at a uniform speed, the rotation amplitudes of the inner ring and the outer ring of the bearing are not proportional, and the rotation amount of the inner ring of the bearing measured by the attachment block 805, the connecting rod 804, the sealing cover 803 and the encoder 802 is not proportional to the running time of the external drive motor 602. The external industrial control device receives the signal of "the rotation amplitude of the inner ring and the outer ring of the bearing is not proportional", and controls the roller re-spraying unit 7 to repaint the roller separately.

[0045] The working principle of the roller spraying unit 7 is as follows: under the signal control of the external industrial control device, the spraying electric push rod 701 contracts, so that the connecting arm 702, the spraying motor 703, the radial positioning ring 704, the traction rod 705 and the axial traction ring 706 move downward. In the multiple groups of traction rods 705 in the circular array, the traction protrusion 7051 is located in the part of the traction rod 705 in the upper avoidance flat rail 7071, and the bottom is suspended above the retaining frame of the bearing. In the multiple groups of traction rods 705 in the circular array, the traction protrusion 7051 is located in the part of the traction rod 705 in the lower contact flat rail 7072, and the bottom is pressed against the roller of the bearing. The spraying motor 703 drives the radial positioning ring 704 to rotate, and causes the multiple groups of vertically sliding traction rods 705 in the radial positioning ring 704 to rotate axially synchronously. When the traction rod 705 rotates relative to the axis of the supplementary injection motor 703, the traction protrusion 7051 maintains a sliding engagement connection relationship with the axial traction recessed track 707 in the axial traction ring 706. Therefore, the multiple groups of traction rods 705 will undergo lifting and reciprocating motions during the rotation process. Specifically, any traction protrusion 7051 moves in the connecting arc track 7073 and enters and exits between the upper avoidance flat track 7071 and the lower contact flat track 7072. The traction rod 705 where the traction protrusion 7051 is located rises and falls with the contour of the connecting arc track 7073. Just above the part of the retaining frame that shields the roller, the bottom of the traction rod 705 is suspended in the air. Just above the part of the roller that is not shielded, the bottom of the traction rod 705 maintains a contact relationship with the outer surface of the roller. Therefore, under the rotation of the supplementary spraying motor 703 and the vertical traction of the axial traction ring 706, multiple groups of traction rods 705 in a circular array can avoid mechanical interference with the retaining frame and drive the stuck roller to rotate, so that the roller stuck with the retaining frame can receive comprehensive paint spraying.

[0046] After the paint spraying of the current roller is completed, the external drive motor 602 is paused. The main lifting electric push rod 10 drives the bearing above the workbench 2 to temporarily descend and move away from the locking column 605. The upper indexing motor 11 drives the main frame 4, the C-shaped ring 604, the locking column 605 and the roller re-spraying unit 7 to rotate through a preset angle (equivalent to the axis angle between adjacent rollers of the sprayed bearing), so that the roller re-spraying unit 7 is aimed at another roller that has not been fully sprayed, and the above-mentioned spraying operation is repeated.

[0047] When all rollers of the bearing to be sprayed are fully sprayed, the middle spray gun 503 is closed, and the outer spray gun 501 and the inner spray gun 502 are opened. Under the condition that the outer drive motor 602 and the drive wheel 603 drive the outer ring of the bearing to rotate, the bearing rollers realize the transmission between the inner ring and the outer ring of the bearing, and cooperate with the outer spray gun 501 and the inner spray gun 502 to fully spray the inner ring and the outer ring of the bearing.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
