Description

Technical Field

[0001] This application relates to the technical field of bolt processing, and in particular to a bolt painting device. Background Technology

[0002] A bolt is a cylindrical fastener with external threads that is used in conjunction with a nut to achieve a detachable connection between two or more components through axial preload. A bolt generally consists of two parts: a head and a shank, with the shank having threads. To ensure the proper engagement of the threads on the shank, surface treatments such as painting are usually required.

[0003] The conventional method for painting bolts in factories is to lay several bolts evenly on a plate and then spray paint them directly with a spray gun. While this method is simple, direct, and fast, it is difficult to guarantee the uniformity of the paint. Furthermore, after one side is painted, workers still need to manually turn the bolts over, causing them to come into direct contact with the freshly painted paint. This not only affects the painting effect on the bolts but also makes it easy for workers to get paint on them, which is detrimental to their health. Utility Model Content

[0004] To improve the uniformity of bolt painting, this application provides a bolt painting device.

[0005] This application provides a bolt painting device, which adopts the following technical solution:

[0006] A bolt painting device includes a frame and a spray gun mounted on the frame. A worktable is horizontally slidable on the frame, and bolts are placed on the worktable. The spray gun paints the bolts on the worktable. A moving mechanism is provided on the frame to drive the worktable to move horizontally. Several fixed seats are evenly distributed on the worktable along the direction of movement. Each fixed seat has a "V"-shaped placement groove, and bolts are placed in the placement groove of the fixed seat. A rotating mechanism is provided on the worktable to drive the bolts located in the placement grooves to rotate.

[0007] By adopting the above technical solution, after the bolt is placed on the fixed seat, the rotating mechanism drives the bolt to rotate in the placement groove, and then the spray gun is started to spray paint on the bolt. This realizes the work of spraying paint while the bolt is rotating, eliminating the need for manual rotation and flipping, improving the uniformity of bolt painting while reducing labor intensity. The moving mechanism drives the worktable to move horizontally, which allows several bolts to be painted one by one, ensuring the efficiency of bolt painting.

[0008] Optionally, the moving mechanism includes:

[0009] A movable lead screw, which is rotatably mounted on the frame and threadedly connected to the worktable;

[0010] A movable motor is mounted on the frame and its output shaft is connected to a movable lead screw.

[0011] By adopting the above technical solution, the moving motor starts and drives the moving lead screw to rotate, and the rotation of the moving lead screw drives the worktable to move, thereby realizing the movement of the worktable by controlling the moving motor.

[0012] Optionally, the rotating mechanism includes:

[0013] The first rotating rod is rotatably mounted on the worktable. There are several first rotating rods, which are evenly distributed along the moving direction of the worktable. The number of first rotating rods corresponds to the number of fixed seats.

[0014] An electric linear actuator is provided, which is mounted on the worktable. Several electric linear actuators are provided, and the number of electric linear actuators corresponds to the number of first rotating rods. The electric linear actuators and the first rotating rods are located on both sides of the fixed base.

[0015] The second rotating rod is rotatably mounted on the electric push rod, and the second rotating rod cooperates with the first rotating rod to clamp the bolt under the action of the electric push rod;

[0016] A drive assembly is mounted on a worktable and is used to drive a plurality of first rotating rods to rotate.

[0017] By adopting the above technical solution, after the bolt is placed on the fixed seat, the electric push rod is started to drive the second rotating rod to move and push the bolt to move until the bolt contacts the first rotating rod. After the second rotating rod and the first rotating rod cooperate to clamp the bolt, the drive assembly is started to drive the first rotating rod to rotate. The rotation of the first rotating rod drives the bolt and the second rotating rod to rotate, thereby completing the rotation of the bolt.

[0018] Optionally, the driving component includes:

[0019] A drive motor is mounted on the worktable and connected to one of the first rotating rods among a plurality of first rotating rods;

[0020] A drive gear is mounted on a first rotating rod, and the drive gears on two adjacent first rotating rods mesh with each other.

[0021] By adopting the above technical solution, the drive motor starts and drives the first rotating rod to rotate. The rotation of the first rotating rod drives the drive gear to rotate. The rotation of the drive gear on one first rotating rod can drive the drive gear adjacent to that first rotating rod and the first rotating rod to rotate. Thus, the rotation of each first rotating rod is realized by controlling the drive motor.

[0022] Optionally, a first sprocket is provided on the output shaft of the drive motor, and a second sprocket is provided on the first rotating rod. The diameter of the first sprocket is smaller than the diameter of the second sprocket, and a transmission chain is sleeved on the first sprocket and the second sprocket.

[0023] By adopting the above technical solution, a first sprocket, a second sprocket, and a transmission chain are installed between the drive motor and the first rotating rod. By setting the diameter of the first sprocket to be smaller than the diameter of the second sprocket, the rotation speed of the drive motor transmitted to the first rotating rod is reduced, making the rotation of the bolt more stable and balanced.

[0024] Optionally, two worktables are provided, arranged in a direction perpendicular to the direction of movement of the worktables. A turntable is rotatably mounted on the frame. The two worktables and two sets of moving mechanisms that drive the two worktables to move are all mounted on the turntable. A rotating mechanism is provided on the frame to drive the turntable to rotate.

[0025] By adopting the above technical solution, a turntable is installed on the frame, and two workbenches are installed on the turntable. By controlling the drive mechanism to rotate the turntable, the two workbenches can alternately carry out painting work. When one workbench is painting bolts, the worker can take out the painted bolts or put the unpainted bolts on the other workbench, which greatly improves work efficiency.

[0026] Optionally, the rotating mechanism includes:

[0027] Rotate the gear ring, which is mounted on the turntable;

[0028] A rotating gear, which is rotatably mounted on the frame and meshes with a rotating gear ring;

[0029] A rotating motor is mounted on the frame;

[0030] A first bevel gear, which is mounted on a rotating gear;

[0031] The second bevel gear is mounted on the output shaft of the rotating motor and meshes with the first bevel gear.

[0032] By adopting the above technical solution, the rotating motor starts and drives the second bevel gear to rotate, the second bevel gear rotates and drives the first bevel gear to rotate, the first bevel gear rotates and drives the rotating gear to rotate, the rotating gear rotates and drives the rotating gear ring to rotate, and the rotating gear ring rotates and drives the turntable to rotate, thereby realizing the rotation of the turntable by controlling the rotating motor.

[0033] Optionally, a protective cover made of transparent acrylic material is rotatably mounted on the frame, which covers the spray gun and the worktable near the spray gun under the action of gravity.

[0034] By adopting the above technical solution, a protective cover is installed on the frame to cover the spray gun and a workbench where the spray gun is spraying paint, thereby reducing the probability of paint splashing in the working environment when the spray gun is working, and protecting the workers who are picking up bolts on another workbench.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By using a rotating mechanism to drive the bolt to rotate in the placement slot, and then starting the spray gun to spray paint the bolt, the bolt can be painted while rotating, eliminating the need for manual rotation and flipping. This improves the uniformity of bolt painting while reducing labor intensity. By using a moving mechanism to drive the worktable to move horizontally, several bolts can be painted one by one, ensuring the efficiency of bolt painting.

[0037] 2. By installing a turntable on the frame and two worktables on the turntable, the two worktables can be rotated alternately by controlling the drive mechanism to perform painting work. This allows the operator to take out painted bolts or place unpainted bolts on the other worktable while one worktable is painting bolts, which greatly improves work efficiency.

[0038] 3. By installing a protective cover on the frame to cover the spray gun and a workbench where the spray gun is being used, the probability of paint splashing into the work environment during spray gun operation is reduced, and workers retrieving bolts from another workbench are protected.

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0044] This application discloses a bolt painting device.

[0045] Reference Figure 1 The bolt painting device includes a frame 1 and a spray gun 11 fixedly mounted on the frame 1. A turntable 12 is rotatably mounted on the frame 1, located on one side of the spray nozzle of the spray gun 11. A horizontal sliding groove 13 is formed on the surface of the turntable 12, and two worktables 14 are horizontally slidably mounted on the turntable 12 through the sliding groove 13. Bolts are placed on the worktables 14 and painted by the spray gun 11.

[0046] Reference Figure 2 The frame 1 is equipped with a rotating mechanism 2 for driving the turntable 12 to rotate. The rotating mechanism 2 includes a rotating gear ring 21, a rotating gear 22, a rotating motor 23, a first bevel gear 24, and a second bevel gear 25. The rotating gear ring 21 is fixedly mounted on the outer wall of the turntable 12. The rotating gear 22 is fixedly mounted on the frame 1 and meshes with the rotating gear ring 21. The rotating motor 23 is fixedly mounted on the frame 1. The first bevel gear 24 is fixedly mounted on the rotating gear 22 and is coaxial with the rotating gear 22. The second bevel gear 25 is fixedly mounted on the output shaft of the rotating motor 23 and meshes with the first bevel gear 24.

[0047] Reference Figure 2 The rotating motor 23 starts and drives the second bevel gear 25 to rotate. The rotation of the second bevel gear 25 drives the first bevel gear 24 to rotate. The rotation of the first bevel gear 24 drives the rotating gear 22 to rotate. The rotation of the rotating gear 22 drives the rotating gear ring 21 to rotate. The rotation of the rotating gear ring 21 drives the turntable 12 to rotate. Thus, the rotation of the turntable 12 is achieved by controlling the rotating motor 23.

[0048] Reference Figure 2 and Figure 3The turntable 12 is equipped with a moving mechanism 3 for controlling the movement of the worktable 14 along the sliding groove 13. The moving mechanism 3 includes a moving lead screw 31 and a moving motor 32. The moving lead screw 31 is rotatably mounted on the turntable 12 and is arranged horizontally. The moving lead screw 31 meshes with the worktable 14. The moving motor 32 is fixedly mounted on the outer wall of the turntable 12 and its output shaft is connected to the moving lead screw 31. When the moving motor 32 is started, it drives the moving lead screw 31 to rotate, and the rotation of the moving lead screw 31 drives the worktable 14 to move. Thus, the movement of the worktable 14 is achieved by controlling the moving motor 32.

[0049] Reference Figure 1 and Figure 2 Several fixed seats 15 are evenly distributed and fixed on the upper surface of the worktable 14 along the moving direction of the worktable 14. A "V"-shaped placement groove 16 is opened on the upper surface of the fixed seat 15, and the bolt is placed in the placement groove 16 of the fixed seat 15. A rotating mechanism 4 is provided on the worktable 14, which is used to drive the bolt located in the placement groove 16 to rotate.

[0050] Reference Figure 2 and Figure 3 The rotating mechanism 4 includes a first rotating rod 41, an electric push rod 42, a second rotating rod 43, and a drive assembly 44. Several first rotating rods 41 are provided, all rotatably mounted on the upper surface of the worktable 14 and evenly distributed along the moving direction of the worktable 14. The position and number of the first rotating rods 41 correspond one-to-one with the position and number of the fixed seats 15. Several electric push rods 42 are fixedly mounted on the upper surface of the worktable 14. The position and number of electric push rods 42 also correspond one-to-one with the position and number of the fixed seats 15. The electric push rods 42 and the first rotating rods 41 are located on opposite sides of the fixed seats 15. The second rotating rod 43 is rotatably mounted on the end of the electric push rod 42 near the fixed seat 15. The drive assembly 44 is disposed on the worktable 14 and is used to drive the several first rotating rods 41 to rotate.

[0051] Reference Figure 2 and Figure 3 After the bolt is placed on the fixed seat 15, the electric push rod 42 is started to drive the second rotating rod 43 to move and push the bolt to move until the bolt abuts against the first rotating rod 41. After the second rotating rod 43 and the first rotating rod 41 cooperate to clamp the bolt, the drive assembly 44 is started to drive the first rotating rod 41 to rotate. The rotation of the first rotating rod 41 drives the bolt and the second rotating rod 43 to rotate, thus completing the rotation of the bolt.

[0052] Reference Figure 2 and Figure 3The drive assembly 44 includes a drive motor 45 and a drive gear 46. The drive motor 45 is fixedly mounted on the outer wall of the worktable 14. A first sprocket 47 is fixedly mounted on the output shaft of the drive motor 45. A second sprocket 48 is fixedly mounted on one end of a plurality of first rotating rods 41 away from the fixed base 15. The diameter of the first sprocket 47 is smaller than the diameter of the second sprocket 48. A transmission chain 49 is fitted onto the first sprocket 47 and the second sprocket 48. A drive gear 46 is fixedly mounted on each of the plurality of first rotating rods 41, and the drive gears 46 on adjacent first rotating rods 41 mesh with each other.

[0053] Reference Figure 3 The drive motor 45 starts, causing the first sprocket 47 to rotate. The rotation of the first sprocket 47 drives the transmission chain 49 to rotate, which in turn drives the second sprocket 48 to rotate. The rotation of the second sprocket 48 drives the first rotating rod 41 to rotate, which in turn drives the drive gear 46 to rotate. The rotation of the drive gear 46 on one first rotating rod 41 drives the adjacent drive gear 46 and the first rotating rod 41 to rotate. Thus, the rotation of each first rotating rod 41 is achieved by controlling the drive motor 45.

[0054] Reference Figure 1 A protective cover 17 made of transparent acrylic material is rotatably mounted on the frame 1. Under the action of gravity, the protective cover 17 covers the spray gun 11 and the worktable 14 near the spray gun 11. This reduces the probability of paint splashing into the working environment when the spray gun 11 is working, and protects the workers who are picking up bolts on the other worktable 14.

[0055] The working principle of this application embodiment is as follows:

[0056] After the bolt is placed on the fixed seat 15, the electric push rod 42 is started to drive the second rotating rod 43 to cooperate with the first rotating rod 41 to clamp the bolt. Then the drive motor 45 is started to drive the first rotating rod 41 to rotate. The rotation of the first rotating rod 41 drives the bolt to rotate in the placement groove 16. Then the spray gun 11 is started to spray paint on the bolt, thus realizing the work of spraying paint while the bolt is rotating. There is no need for manual rotation and flipping, which improves the uniformity of bolt painting and reduces the workload.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
