Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically to a novel environmentally friendly liftable and rotating spray booth rotation lifting mechanism. Background Technology

[0002] A lifting and rotating spray booth is a device used for spraying coatings on object surfaces. It controls the position of the worktable through a dual drive system of lifting and rotating. Lifting is used to adjust the height of the worktable and the workpiece on its surface, ensuring that the position of the workpiece corresponds to the position of the spray nozzle, and to ensure that the area of ​​paint sprayed from the nozzle is adapted to the position of the workpiece. Rotation is used to adjust the angle of the worktable and the workpiece on its surface, ensuring that the paint can cover the entire area of ​​the workpiece, and to ensure the uniformity of the paint sprayed on the workpiece surface.

[0003] CN205184714U discloses a novel environmentally friendly, liftable, rotating spray booth lifting mechanism, including a rotating platform and a worktable. The rotating platform has a support frame and guide holes. The worktable has a workpiece fixing device and a railing. The support frame consists of a lower connecting rod and an upper connecting rod. A piston is located on the end face of the upper connecting rod within the lower connecting rod. A hydraulic / pneumatic chamber is located below the piston in the lower connecting rod. A return spring is located above the piston in the lower connecting rod. A guide shaft is located below the worktable. The guide shaft consists of several connecting sections, each with a rubber block at its lower end within the adjacent connecting section below. This novel environmentally friendly, liftable, rotating spray booth lifting mechanism employs a hydraulic / pneumatic working method. The piston and return spring effectively support the frame, and the guide shaft and guide holes provide guidance.

[0004] While the existing technology CN205184714U has many advantages in use, it still has the following problems: it requires two different drive components to operate separately in order to adjust the position of the worktable, which results in high operating costs and high subsequent maintenance costs. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a novel environmentally friendly, liftable, and rotating spray booth rotation lifting mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is a new type of environmentally friendly liftable and rotating spray booth rotary lifting mechanism, including a support platform, bearing seats and a fixed frame. The support platform has a movable hole at its center. The support platform has a rectangular array of bearing seats inside. The bearing seats are fitted with ball bearings with interference fit. The inner ring of the ball bearing is fitted with a connecting shaft with interference fit. The connecting shaft protrudes from the outer wall of the ball bearing and is fitted with a driven gear with interference fit. The inner wall of the connecting shaft is threaded with a guide stud. The outer wall of the support platform is screwed with a fixed frame. The fixed frame has a drive shaft rotatably installed inside.

[0007] By adopting the above technical solution, the synchronous rotation and lifting of the worktable can be driven during the rotation of the drive shaft through the meshing of the driving gear and the driven gear. This ensures the stability of the worktable during rotation and lifting and allows for the adjustment of the position of the workpiece at the top of the worktable. It also integrates the rotation and lifting methods, ensuring that the synchronous drive unit can drive rotation and lifting, reducing the operating cost and subsequent maintenance cost of the equipment. The operator controls the pitch of the screw hole that matches the outer wall of the guide stud and the inner ring of the connecting shaft. After the worktable is driven to the required height, it will only drop by two centimeters after rotating one revolution through the controlled screw hole. This ensures that the relative height of the worktable is maintained while allowing it to rotate, thus ensuring the coating effect on the workpiece at the top of the worktable.

[0008] Specifically, the upper outer wall of the support platform is provided with a rectangular array of assembly holes, the bearing seat is arranged inside the assembly holes, and the upper end of the outer wall of the bearing seat is screwed to the upper outer wall of the support platform.

[0009] By adopting the above technical solution, the mounting hole facilitates the installation and positioning of the bearing housing, and the bearing housing is connected to the bearing platform by screws, making installation and disassembly convenient and beneficial for later maintenance and repair.

[0010] Specifically, the lower end of the guide stud is screwed to a base, and the outer wall of the base is provided with a rectangular array of fixing holes.

[0011] By adopting the above technical solution, the staff can fix the base in the required position by inserting external bolts through the fixing holes, ensuring the stability of the base and guide studs and ensuring that the worktable will not shake or shift during rotation and lifting.

[0012] Specifically, a drive motor for providing power is provided through one end of the outer wall of the fixed frame, the drive shaft is connected to the drive shaft by a coupling, and the drive motor is screwed to the lower outer wall of the fixed frame.

[0013] By adopting the above technical solution, the drive motor can provide stable power output, ensuring the rotational accuracy and stability of the drive shaft, so that the drive shaft can carry the drive gear to rotate and drive the worktable and fence to rotate.

[0014] Specifically, a drive gear is interference-fitted onto the outer wall of one side of the drive shaft. The drive gear is located at the lower end of the support platform and meshes with the driven gear.

[0015] By adopting the above technical solution, the meshing transmission between the driving gear and the driven gear can efficiently transmit the power of the drive shaft to the connecting shaft. When the connecting shaft rotates, the bearing platform can be driven to move vertically through the threaded hole adapted to its inner wall and the guide stud, thus realizing the precise adjustment of the working height.

[0016] Specifically, a workbench is screwed to one end of the drive shaft through the movable hole, and a railing is screwed to the upper end of the workbench.

[0017] By adopting the above technical solution, the workpiece to be sprayed can be placed on the top of the workbench and fixed, and the railing on the top of the workbench can play a protective role and protect the workpiece.

[0018] Specifically, the guide stud is screwed through the outer wall of one end of the roller bearing and connected to a limiting plate, the limiting plate being located at the upper end of the bearing housing.

[0019] By adopting the above technical solution, the limiting plate can limit the rising height of the connecting shaft outside the guide stud, prevent the bearing platform from moving excessively upward, and play a role in limiting protection.

[0020] The beneficial effects of this utility model are:

[0021] The present invention discloses a novel environmentally friendly liftable and rotating spray booth rotation lifting mechanism, which can ensure the stability of the workbench during rotation and lifting, and realize the position adjustment of the workpiece at the upper end of the workbench. It can integrate the rotation and lifting modes, ensure that the synchronous drive unit realizes the drive of rotation and lifting, and reduce the use cost and subsequent maintenance cost of the equipment.

[0022] The present invention discloses a novel environmentally friendly liftable and rotating spray booth rotation lifting mechanism. After the worktable is driven to the required height, it will only drop by two centimeters after rotating one revolution through the controlled screw hole. This allows the worktable to rotate while maintaining its relative height, ensuring the coating effect on the workpiece at the top of the worktable. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, the novel environmentally friendly liftable and rotating spray booth rotary lifting mechanism of this utility model includes a support platform 1, a bearing seat 2, and a fixed frame 3. The support platform 1 has an movable hole 11 at its center. The support platform 1 has a rectangular array of bearing seats 2 inside. A ball bearing 21 is interference-fitted inside the bearing seat 2. A connecting shaft 22 is interference-fitted inside the inner ring of the ball bearing 21. A driven gear 23 is interference-fitted onto the outer wall of the connecting shaft 22 on one side of the ball bearing 21. A guide stud 24 is threaded onto the inner wall of the connecting shaft 22. The fixed frame 3 is screwed onto the outer wall of the support platform 1. A drive shaft 31 is rotatably mounted inside the fixed frame 3.

[0031] During use, the meshing of the driving gear 33 and the driven gear 23 enables the synchronous rotation and lifting of the worktable 34 during the rotation of the drive shaft 31. This ensures the stability of the worktable 34 during rotation and lifting, and allows for position adjustment of the workpiece on the upper end of the worktable 34. The integration of rotation and lifting methods ensures that the synchronous drive unit can drive rotation and lifting, reducing the operating cost and subsequent maintenance cost of the equipment. The operator controls the pitch of the screw hole that matches the outer wall of the guide stud 24 and the inner ring of the connecting shaft 22. After the worktable 34 is driven to the required height, it will only drop by two centimeters after rotating one revolution through the controlled screw hole. This ensures that the relative height of the worktable 34 is maintained while allowing it to rotate, thus ensuring the coating effect on the workpiece on the upper end of the worktable 34.

[0032] To maintain a stable position, for example, such as Figure 1 As shown, the upper outer wall of the support platform 1 has a rectangular array of assembly holes 12, the bearing seat 2 is arranged inside the assembly holes 12, and the upper end of the outer wall of the bearing seat 2 is screwed to the upper outer wall of the support platform 1.

[0033] In use, the mounting hole 12 facilitates the installation and positioning of the bearing housing 2, and the bearing housing 2 is connected to the support platform 1 by screws, making installation and disassembly convenient and beneficial for later maintenance and repair.

[0034] To maintain the usage location, for example, such as Figure 2 As shown, the lower end of the guide stud 24 is screwed to the outer wall of the base 26, and the outer wall of the base 26 has a rectangular array of fixing holes.

[0035] During use, the operator can fix the base 26 in the required position by passing the external bolts through the fixing holes, ensuring that the base 26 and the guide stud 24 are in a stable position and that the worktable 34 will not shake or shift during rotation and lifting.

[0036] To drive rotation, for example, such as Figure 3 As shown, a drive motor 32 for providing power is provided through the outer wall of one end of the drive shaft 31. The drive motor 32 and the drive shaft 31 are connected by a coupling, and the drive motor 32 is connected to the lower outer wall of the fixed frame 3 by screws.

[0037] When in use, the drive motor 32 can provide stable power output, ensuring the rotational accuracy and stability of the drive shaft 31, so that the drive shaft 31 can carry the drive gear 33 to rotate, and can drive the worktable 34 and the fence 35 to rotate.

[0038] For synchronized rotation, for example, such as Figure 2As shown, a drive gear 33 is interference-fitted onto the outer wall of one side of the drive shaft 31. The drive gear 33 is located at the lower end of the support platform 1, and the drive gear 33 meshes with the driven gear 23.

[0039] In use, the meshing transmission between the drive gear 33 and the driven gear 23 can efficiently transmit the power of the drive shaft 31 to the connecting shaft 22. When the connecting shaft 22 rotates, it can drive the support platform 1 to move vertically through the guide stud 24 via the threaded hole adapted to its inner wall, thus realizing the precise adjustment of the working height of the worktable 34.

[0040] To secure the workpiece, for example, such as Figure 3 As shown, the drive shaft 31 passes through the movable hole 11 and is screwed to the outer wall of one end to connect to the worktable 34. The upper outer wall of the worktable 34 is screwed to connect to the railing 35.

[0041] When in use, the workpiece to be sprayed can be placed on the upper part of the workbench 34 for fixation, and the railing 35 on the upper part of the workbench 34 can play a protective role to protect the workpiece.

[0042] To limit the distance of movement, for example, such as Figure 4 As shown, the guide stud 24 passes through the outer wall of one end of the roller bearing and is screwed to the limit plate 25. The working height of the limit plate 25 is located at the upper end of the bearing seat 2.

[0043] When in use, the limiting plate 25 can limit the rising height of the connecting shaft 22 outside the guide stud 24, preventing the bearing platform 1 from moving too high, and playing a role in limiting protection.

[0044] In use, the operator uses external bolts to pass through the fixing holes on the base 26 to securely install the base 26 in the designated position of the spray booth, ensuring the stability of the entire mechanism. The operator then places the workpiece to be sprayed on the workbench 34 and secures it.

[0045] Start the drive motor 32, and the drive shaft 31 drives the drive gear 33 to rotate. Since the drive gear 33 meshes with the driven gear 23, the driven gear 23 drives the connecting shaft 22 to rotate within the ball bearing 21. The thread on the inner wall of the connecting shaft 22 engages with the guide stud 24, causing the support platform 1 to move vertically along the guide stud 24, thereby adjusting the worktable 34 to the initial spraying height;

[0046] After the worktable 34 is moved to the desired position, the drive motor 32 continues to work, and the drive shaft 31 drives the worktable 34 and the fence 35 to rotate in opposite directions. At the same time, the drive gear 33 drives the connecting shaft 22 to rotate through the driven gear 23.

[0047] By controlling the pitch of the threaded holes that match the outer wall of the guide stud 24 and the inner ring of the connecting shaft 22, the worktable 34 rotates one revolution and then drops only 2 centimeters, thus achieving precise control of the workpiece spraying position and ensuring that the paint can evenly cover the workpiece surface.
