Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment, and in particular to a lifting and tilting mechanism that is easy to use in a spray painting machine room. Background Technology

[0002] In modern manufacturing, painting is an extremely important surface treatment process that directly affects the appearance and protective performance of products. Therefore, the efficiency and quality of painting booth operations are of paramount importance.

[0003] Currently, many paint booths use cranes to lift workpieces and place them on fixed mechanisms. These fixed mechanisms only serve a supporting function, and the workpieces cannot be rotated after being fixed. In order to achieve full painting, the workpieces can only be turned over manually. Manual turning is not only extremely inefficient, but also requires multiple people to turn large and heavy workpieces, and each operation takes a long time, which seriously slows down the production progress. Moreover, when manually turning heavy workpieces, the labor intensity is high, and there is a safety hazard of workpieces slipping and injuring people.

[0004] In view of this, we propose a lifting and tilting mechanism that is easy to use in paint spraying rooms, so as to improve the operation level of paint spraying rooms and meet the needs of modern production. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting and tilting mechanism that is easy to use in a paint spraying room. By using this device, the existing problems in the background art mentioned above can be solved.

The top of the annular sliders is fixedly connected to the bottom of the worktable.

[0008] Preferably, the first rotary drive assembly includes a first motor, which is mounted in the base. A first drive gear is fixedly connected to the surface of the output shaft of the first motor, and a driven gear is meshed with one side of the first drive gear. The driven gear is coaxial with the rotary bearing and fixedly connected to the bottom of the worktable.

[0009] Preferably, the top of the workbench is fixedly connected to a first support frame on both sides of each arc-shaped slide rail, and the support wheel is rotatably disposed in the first support frame.

[0010] Preferably, there are three reinforcing beams, which are respectively fixedly connected to the two ends and corners of the two right-angle bearing frames, and reinforcing plates are fixedly connected between adjacent reinforcing beams.

[0011] Preferably, the fastening assembly includes a displacement groove penetrating the side wall of the load-bearing beam in the right-angle support frame, a displacement block slidably connected in the displacement groove, a lead screw rotatably connected in the displacement groove, the surface of the lead screw being threadedly connected to the displacement block, a handle being coaxially fixedly connected to one end of the lead screw through the side wall of the displacement groove, a second support frame being fixedly connected to the top of the displacement block, an L-shaped fastening plate being fixedly connected to the second support frame, and a rubber pad being installed on the side of the fastening plate near another load-bearing beam in the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This system improves turnover efficiency and eliminates the safety hazards of manual turnover.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figures 1-4 A lifting and tilting mechanism for easy use in a paint spraying room includes a base 1, a worktable 2 rotatably connected to the top of the base 1, a first rotary drive assembly 3 between the base 1 and the worktable 2, allowing the worktable 2 to rotate horizontally under the action of the first rotary drive assembly 3, two right-angle support frames 4 above the worktable 2 for supporting workpieces to be painted, an arc-shaped slide rail 5 fixedly connected to the outer wall of each right-angle support frame 4, a second rotary drive assembly 9 below the arc-shaped slide rail 5, and rotary drives on both sides of each arc-shaped slide rail 5 above the worktable 2. The device is equipped with a support wheel 6, which is rotatably connected to the arc-shaped slide rail 5 via a slot. The support wheel 6 provides support for the right-angle support frame 4. The second rotary drive assembly 9 is responsible for driving the right-angle support frame 4 to rotate around the support wheel 6, thereby enabling the workpiece to flip in the vertical direction. A reinforcing beam 7 is fixedly connected between the two right-angle support frames 4, making the two right-angle support frames 4 form a whole. Each support beam in each right-angle support frame 4 is equipped with a fastening assembly 8, which is used to firmly fix the workpiece on the right-angle support frame 4 to prevent the workpiece from shifting during flipping and painting.

[0023] A rotary bearing 10 is installed between the top center of the base 1 and the bottom center of the worktable 2. The inner ring of the rotary bearing 10 is fixed to the bottom center of the worktable 2, and the outer ring is fixed to the top center of the base 1. An annular groove 11 coaxial with the rotary bearing 10 is provided on the top of the base 1. Three annular sliders 12 are slidably connected in the annular groove 11. The top of the annular sliders 12 is fixedly connected to the bottom of the worktable 2. The annular sliders 12 share the weight of the worktable 2 and the workpiece, reducing the shaking when the worktable 2 rotates, so that the worktable 2 can rotate more smoothly and accurately under the drive of the first rotary drive assembly 3.

[0024] The first rotary drive assembly 3 includes a first motor 31, which is mounted in the base 1. A first drive gear 32 is fixedly connected to the output shaft surface of the first motor 31. A driven gear 33 is meshed with one side of the first drive gear 32. The driven gear 33 is coaxial with the rotary bearing 10 and fixedly connected to the bottom of the worktable 2. When the first drive gear 32 rotates, it drives the driven gear 33 to rotate through the meshing action, thereby driving the worktable 2 to rotate around the rotary bearing 10. By adjusting the speed and direction of the first motor 31, the rotation speed and angle of the worktable 2 can be precisely controlled, making it convenient to adjust different sides of the workpiece to the appropriate painting position.

[0025] The top of the workbench 2 is fixedly connected to the first support frame 13 on both sides of each arc-shaped slide rail 5, and the support wheel 6 is rotatably set in the first support frame 13.

[0026] There are three reinforcing beams 7, which are fixedly connected to the two ends and corners of the two right-angle bearing frames 4 respectively, forming a whole for the two right-angle bearing frames 4 from multiple directions. Reinforcing plates 14 are fixedly connected between adjacent reinforcing beams 7 to enhance the connection stability between the two right-angle bearing frames 4.

[0027] The fastening assembly 8 includes a displacement groove 81 that penetrates the side wall of the load-bearing beam in the right-angle support frame 4. A displacement block 82 is slidably connected in the displacement groove 81, and a lead screw 83 is rotatably connected in the displacement groove 81. The surface of the lead screw 83 is threadedly connected to the displacement block 82. One end of the lead screw 83 passes through the side wall of the displacement groove 81 and is coaxially fixedly connected to a handle 84. A second support frame 85 is fixedly connected to the top of the displacement block 82. An L-shaped fastening plate 86 is fixedly connected to the second support frame 85. A rubber pad is installed on the side of the fastening plate 86 near another load-bearing beam in the support frame. When it is necessary to fix the workpiece, the handle is rotated... Handle 84 drives lead screw 83 to rotate. Due to the threaded engagement between lead screw 83 and displacement block 82, the rotation of lead screw 83 is converted into linear movement of displacement block 82 in displacement groove 81. The second support frame 85 and fastening plate 86 fixedly connected to the top of displacement block 82 move, tightly fixing the workpiece between the two fastening plates 86. The rubber pad installed on the side of fastening plate 86 near another bearing beam in the bearing frame not only increases the friction between it and the workpiece, effectively preventing the workpiece from sliding during the fixing process, but also avoids the fastening plate 86 directly contacting the surface of the workpiece and causing damage.

[0028] The dual-drive assembly 9 includes a second motor 91, which is mounted on the top of the worktable 2. A second drive gear 92 is fixedly connected to the output shaft of the second motor 91. An arc-shaped rack 93 is meshed with one side of the second drive gear 92. The arc-shaped rack 93 is fixedly mounted on the side wall of one of the arc-shaped slide rails 5. When the second drive gear 92 rotates, due to the fixed connection between the arc-shaped rack 93 and the arc-shaped slide rail 5, the arc-shaped slide rail 5 and the right-angle support frame 4 connected to it rotate around the support wheel 6 under the meshing transmission action of the gear and rack. By controlling the speed and direction of the second motor 91, the rotation angle and speed of the right-angle support frame 4 can be precisely adjusted, realizing the precise vertical flipping of the workpiece, so that all surfaces of the workpiece can smoothly reach the painting position.

[0029] Working principle:

[0030] In the initial state, the right-angle support frame 4 faces the spraying direction, and the two support beams of the support frame 4 are in a vertical and horizontal state respectively. The workpiece to be sprayed is hoisted onto the right-angle support frame 4 by a crane. The workpiece is fastened by the fastening components 8 on the two horizontal support beams. When the fastening components 8 are operated, the handle 84 is turned, which drives the lead screw 83 to rotate. The lead screw 83 drives the displacement block 82 to slide in the displacement groove 81, so that the L-shaped fastening plate 86 connected to the displacement block 82 moves until the workpiece is firmly fixed, ensuring the stability of the workpiece during the processing.

[0031] After the workpiece is fixed, the second motor 91 is started. The output shaft of the second motor 91 drives the second drive gear 92 to rotate. The second drive gear 92 meshes with the arc-shaped rack 93, pushing the arc-shaped slide rail 5 and the right-angle support frame 4 connected to it to rotate 90 degrees around the support wheel 6, completing the vertical flipping of the workpiece. Then the first motor 31 is started. The first motor 31 drives the first drive gear 32, which meshes with the driven gear 33, causing the worktable 2 to rotate around the rotary bearing 10. During the rotation of the worktable 2, the three sides of the workpiece face the spraying direction in sequence, and the three sides can be sprayed and dried.

[0032] After completing the first three-sided processing, the fastening component 8, which is currently on the horizontal bearing beam, is operated to fix the workpiece again. The first motor 31 and the second motor 91 are started again. Through the opposite action of the first flipping and rotation, the right-angle bearing frame 4 and the worktable 2 are restored to their initial orientation. At this time, the fastening component 8 used to fix the workpiece is released, and the previously unprocessed surfaces of the workpiece are sprayed and dried.

[0033] After the above processing is completed, the workpiece is lifted by a crane, the first motor 31 is started to rotate the worktable 2 180 degrees, and the workpiece is then lifted back onto the right-angle support frame 4 by the crane. At this time, the two sides of the workpiece that were previously in contact with the right-angle support frame 4 and were not sprayed are exposed. The previous fastening operation is repeated, and the workpiece is fixed by the fastening component 8. The first motor 31 and the second motor 91 are started again to control the rotation of the worktable 2 and the right-angle support frame 4. The two newly exposed sides of the workpiece and the remaining unprocessed parts are sprayed and dried accordingly to ensure that all six sides of the workpiece are sprayed and dried with high quality.

[0034] After all six sides of the workpiece have been processed, the painted workpiece is lifted from the right-angle support frame 4 by a crane, completing the entire workflow and waiting for the next batch of workpieces to enter the paint booth for processing.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
