Description

Technical Field

[0001] The present invention relates to the field of mechanical engineering equipment, and particularly to a rotary painting carrier trolley. Background Art

[0002] Rotary painting carriers are usually used for spraying paint on workpieces and can perform spray painting on multiple workpieces in a production line. Existing rotary painting carriers mostly adopt the form of a trolley structure, designed in an integrated shape similar to a bowling pin, with a circular arc at the top to support the tool to be painted. The lower part is internally provided with a bearing sleeve and a bearing, and is equipped with an internal circlip to provide sliding rotation, and finally assembled with the trolley.

[0003] However, due to the simplicity of the design of existing rotary painting carriers, when the carrier is deformed, the entire carrier must be replaced, resulting in too high maintenance costs. Since the workpiece support part is designed as a circular arc, the complete contact between the workpiece support part and the carrier support part causes the contact surface not to be sprayed during the subsequent spraying process, resulting in the phenomenon of missed spraying on the support surface. Since the workpiece is sprayed while rotating and the original number of rotation circles cannot be accurately controlled, the film thickness of the coating on the workpiece surface does not meet the standard during spraying, and there are defects such as missed spraying and overspraying, resulting in losses of human and material resources for the user. When the subsequent manufacturing process requires the rotation to stop immediately, since the carrier for assembling the workpiece cannot eliminate the inertia of rotation in time and stop, it cannot meet the process requirements that the workpiece needs to stop rotating in a short time in the subsequent process, seriously affecting the subsequent quality requirements. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a rotary painting carrier trolley, which is used to solve the problems of too high maintenance costs, non-compliance of the film thickness of the coating on the workpiece surface, and inability to guarantee the subsequent quality requirements in the prior art.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope within which the present invention can be implemented.

[0024] As Figures 1 to 4 shown, the present invention provides a rotary coating carrier trolley, including a cross-shaped support frame 1, a wine bottle-shaped support 2, a rotary base 3, a cylindrical bearing mount 4, a rotary shaft seat 5, and a trolley chassis 6. The cross-shaped support frame 1, the wine bottle-shaped support 2, the rotary base 3, the cylindrical bearing mount 4, the rotary shaft seat 5, and the trolley chassis 6 are arranged and connected in sequence from top to bottom.

[0025] A first cylindrical groove 11 is provided at the bottom of the cross-shaped support frame 1, and the thinner end of the wine bottle-shaped support 2 is connected to the first circular groove 11. A second cylindrical groove 21 is provided inside the thicker end of the wine bottle-shaped support 2. A connecting shaft 31 is connected to the center position of the rotary base 3, and the connecting shaft 31 is connected to the second cylindrical groove 21 through clearance fit. This clearance allows the connecting shaft 31 to rotate inside the second cylindrical groove 21.

[0026] The wine bottle-shaped support 2 is composed of a thinner tubular body, a cone, and a thicker tubular body connected in sequence. A number of exhaust through-holes 22 are provided inside the thicker end of the wine bottle-shaped support 2. One end of the exhaust through-hole 22 leads to the second cylindrical groove 21, and the other end leads to the surface of the thicker end of the wine bottle-shaped support 2. When the connecting shaft 31 on the rotary base 3 is inserted into the second cylindrical groove 21, air can be discharged through the exhaust through-holes 22 to eliminate residual air, solving the problem of the original tight fit being impossible due to the remaining residual air.

[0027] At the top of the cross-shaped support frame 1, there is a tap through-hole 12, and a third bolt 13 is screwed into the tap through-hole. By screwing the third bolt 13 forcefully, the thinner end of the wine-bottle-shaped support 2 can be pushed out from the first cylindrical groove 11, so that the cross-shaped support frame 1 is separated from the wine-bottle-shaped support 2. Four multi-step support surfaces 14 are provided around the top of the cross-shaped support frame 1, thus forming a cross shape. The four multi-step support surfaces 14 increase the coating coverage area of the tool support surface, adapt to the mixed-line production required for workpieces of different sizes, and achieve the flexible production goal expected by the customer. A positioning pin hole 15 is also provided inside the cross-shaped support frame 1, and the cross-shaped support frame 1 is more firmly connected to the wine-bottle-shaped support 2 by cooperating with a positioning pin.

[0028] The rotating base 3 is connected to the cylindrical bearing mounting seat 4 by three first bolts 32, and the first bolts 32 are M6*20 hexagon socket head cap screws. One end at the center position of the cylindrical bearing mounting seat 4 is provided with a third cylindrical groove 47, and the other end is provided with a cylindrical through-hole. A first bearing 41, a sleeve 42, a second bearing 43, and a circlip 44 are provided in the third cylindrical groove 47. A rotating shaft 51 is provided at the center position of the rotating shaft seat 5, and the rotating shaft 51 sequentially passes through the circlip 44, the second bearing 43, the sleeve 42, and the first bearing 41 from the bottom of the cylindrical bearing mounting seat 4 and is installed inside the cylindrical bearing mounting seat 4. Both the first bearing 41 and the second bearing 43 are deep groove ball bearings, and the model is 6005-2Z. Two wheels 61 are respectively installed on both sides of the trolley chassis 6.

[0029] A second gasket 45 is also provided in the third cylindrical groove 47, and the second gasket 45 is installed on the top of the first bearing 41. A threaded hole is provided inside the top of the rotating shaft 51, and the first bearing 41, the sleeve 42, the second bearing 43, and the circlip 44 are fixed on the rotating shaft 51 by screwing a second bolt 46 into the threaded hole.

[0030] A first gasket 7 is provided between the wine-bottle-shaped support 2 and the rotating base 3, and the first gasket 7 is a Teflon gasket. The Teflon gasket enables the wine-bottle-shaped support 2 to stop in time by overcoming the inertia after the rotating base 3 stops rotating, meets the process requirements of the subsequent process of the user, and solves the quality defects in the subsequent process.

[0031] Four notches 48 are circumferentially arrayed on the surface of the cylindrical bearing mounting seat 4 near the bottom. The four notches 48 are used as four point detections, and combined with the external sensors on the production line, it can accurately control according to the different required number of rotation circles when spraying various workpieces by the user, meet the high requirements for the appearance and film thickness of the coating, eliminate the phenomena of overspray and missed spray, save the coating consumption, and achieve the goal of green manufacturing.

[0032] When this rotary painting carrier trolley works on the assembly line, the workpiece to be painted is placed on the cross-shaped support frame 1, and the cylindrical bearing mount 4 is closely attached to the conveyor belt rotating on the assembly line. When the conveyor belt rotates, it drives the rotation of the cylindrical bearing mount, thereby driving the rotation of the wine bottle-shaped bracket 2. The rotation of the wine bottle-shaped bracket 2 drives the cross-shaped support frame 1, so that the workpiece to be painted also rotates accordingly. At the same time, the painting machine beside the conveyor line will paint the rotating workpiece to be painted.

[0033] In summary, for a rotary painting carrier trolley of the present invention, through delicate design, the whole is easy to disassemble and install, saving the costs of manpower, material resources and time; through 4-point detection and combined with external sensors, it can accurately control according to the different required number of rotation circles when spraying various workpieces by the user, meeting the high requirements for the appearance and film thickness of the coating; a Teflon gasket is provided between the wine bottle-shaped bracket and the rotary base, enabling the carrier and the supported workpiece to stop in time by overcoming the inertia after the rotary base stops rotating, meeting the technological requirements of the subsequent process of the user and solving the quality defects in the subsequent process.
