Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a multi-axis robot for rudder compartment plasma spraying. Background Technology

[0002] Plasma spraying is a technology that uses a high-temperature plasma arc to melt powder materials and spray them onto the surface of a substrate to form a coating. The rudder compartment is an important component in transportation vehicles such as ships and aircraft, and its surface needs to withstand corrosion from various harsh environments. In order to improve the corrosion resistance, wear resistance, and fatigue resistance of the rudder compartment, plasma spraying technology is usually used to form a protective coating on its surface.

[0003] A search revealed a utility model patent with Chinese patent publication number CN108704790A, which discloses a powder coating robot for aluminum alloy profiles. The robot includes a coating robot assembly and a control box. A fixed frame is fixedly installed at the lower end of the coating robot assembly, and a rotating shaft is movably installed at the upper end of the coating robot assembly. A movable arm is movably installed on the inner surface of the rotating shaft, and a spray gun is fixedly installed at one end of the movable arm near the side of the coating robot assembly.

[0004] As mentioned above, robotic arms require a lot of movements during operation. To ensure their stability, the mounting base is usually connected to external equipment by welding or by using multiple bolts for locking. Both methods are time-consuming, and disassembling the robotic arm is also cumbersome, resulting in inflexible use of the machine. Utility Model Content

[0005] The purpose of this invention is to provide a multi-axis robot for plasma spraying of steering gear compartments to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-axis robot for plasma spraying of a rudder bay, comprising a mounting base and a base. The base is placed on top of the mounting base, and the base has two chambers inside. A common connecting component is installed between the mounting base and one chamber at the bottom of the base. The connecting component includes a slot on the outer wall of the top of the mounting base, and the base is located inside the slot. The outer wall of the base has several equally spaced limiting slots, and the limiting slots extend into the base. A plate is slidably inserted into each of the limiting slots, and the plates are inserted precisely into the slots.

[0007] As a further preferred embodiment of this technical solution, a motor is fixedly installed on the inner wall of the top of the base, and a drive frame is coaxially fixed to the output end of the motor. The drive frame consists of several strip rings and a disc. An extension column is fixedly connected to one end of the top of several insert plates, and the extension columns are all cylindrical. Several strip rings on the outside of the drive frame are slidably sleeved on the outside of the extension columns.

[0008] As a further preferred embodiment of this technical solution, a positioning post is coaxially fixed to the outer wall of the bottom of the base, and a slot adapted to the positioning post is provided on the inner wall of the bottom of the slot.

[0009] This invention, by setting up a connecting component, can quickly connect the robotic arm and the mounting base when needed, ensuring sufficient stability of the robotic arm. It eliminates the need for multiple connectors, making operation convenient. Simply insert the positioning pin into the corresponding hole inside the mounting base to position the base, facilitating subsequent connection work. The positioning pin also provides a certain degree of stability, preventing the base from swaying arbitrarily. Next, the motor inside the base is started, and its output drives the drive frame to rotate. The drive frame, through the extension pin, drives the sliding plate inserted into the limiting groove to slide outwards, finally abutting against the inner circumference of the slot. The plate further reinforces the base, ensuring it does not move up or down.

[0010] As a further preferred embodiment of this technical solution, a connecting seat is rotatably connected to the inner circumference of the top cavity of the base via a bearing. A first motor is fixedly installed inside the base, and the first motor is coaxially fixed with the connecting seat. A large arm is hinged to one outer wall of the connecting seat. A second motor is installed inside the connecting seat, and the output end of the second motor is coaxially fixed with the rotation shaft of the large arm. A secondary arm is hinged to one top end of the large arm. A third motor is fixedly installed inside the large arm, and the output end of the third motor is coaxially fixed with the rotation shaft of the secondary arm.

[0011] As a further preferred embodiment of this technical solution, a rotating plate is hinged to one end of the top of the auxiliary arm, a motor is fixedly installed inside the auxiliary arm, and the output end of the motor is coaxially fixed with the rotating shaft of the rotating plate. A clamping assembly is installed outside the rotating plate.

[0012] As a further preferred embodiment of this technical solution, a horizontally arranged mounting plate is fixedly connected to the outer wall of one end of the rotating plate. A horizontally arranged bidirectional lead screw is rotatably connected inside the mounting plate via bearings. A movable plate is threaded onto the threaded ends of both ends of the bidirectional lead screw, and both movable plates are in contact with the inner wall of the top wall of the mounting plate. A clamping plate is fixedly connected to the ends of the two movable plates that are close to each other. The same plasma spraying gun is placed between the two clamping plates. A protective frame is fixedly installed on one side of the outer wall of the mounting plate, and a motor adapted to the bidirectional lead screw is installed inside the protective frame.

[0013] To replace or repair the plasma spray gun, start the motor four on the outer protective frame of the mounting plate. The output of motor four drives the bidirectional lead screw to rotate. The movable plates, which are restricted to translation by the inner wall of the mounting plate, will move away from each other under the drive of the bidirectional lead screw. Subsequently, the two clamping plates will also move away from the spray gun. At this time, the spray gun can be easily removed. The locking blocks on the outside of the clamping plates can prevent the spray gun from moving randomly.

[0014] As a further preferred embodiment of this technical solution, the edge of the card slot and the top edge of several insert plates are all provided with rounded corners.

[0015] This utility model provides a multi-axis robot for plasma spraying of a steering gear, which has the following beneficial effects:

[0016] (1) By setting up a connecting component, this utility model can quickly connect the robotic arm and the mounting base when needed, and ensure that the state of the robotic arm is stable enough. It does not require multiple connecting parts for connection, and the operation is convenient enough. The positioning column is inserted into the corresponding hole inside the mounting base to position the base, which facilitates the smooth progress of subsequent connection work. The positioning column can also play a certain stabilizing role, preventing the base from shaking left and right at will. Then, the motor inside the base is started, and its output end drives the drive frame to start rotating. The drive frame drives the insert plate that is slidably inserted into the limit groove to slide outward through the extension column. Finally, they abut against the inner circumference of the slot. The insert plate can reinforce the base again and ensure that it will not move up and down.

[0017] (2) By setting up a clamping component, if the plasma spray gun needs to be replaced or repaired, start the motor four of the outer protective frame of the mounting plate. The output end of the motor four drives the bidirectional screw to rotate. The moving plate, which is restricted to translation by the inner wall of the mounting plate, will move away from each other under the drive of the bidirectional screw. Then the two clamping plates will also move away from the spray gun. At this time, the spray gun can be easily removed. The locking block outside the clamping plate can prevent the spray gun from moving randomly. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown in this embodiment, a multi-axis robot for plasma spraying of a rudder bay includes a mounting base 1 and a base 2. The base 2 is placed on top of the mounting base 1. The base 2 has two chambers inside. The same connecting component 7 is installed between the mounting base 1 and one of the bottom chambers of the base 2. The connecting component 7 includes a slot 703 opened on the outer wall of the top of the mounting base 1. The base 2 is located inside the slot 703. The outer wall of the circumference of the base 2 has several equally spaced limiting slots 701, and the limiting slots 701 extend into the interior of the base 2. A plate 702 is slidably inserted into each of the limiting slots 701. The plates 702 are inserted into the slots 703.

[0025] A motor 706 is fixedly installed on the inner wall of the top of the base 2. A drive frame 705 is coaxially fixed to the output end of the motor 706. The drive frame 705 consists of several strip rings and a disc. An extension column 704 is fixedly connected to one end of the top of several insert plates 702. The extension columns 704 are all cylindrical. Several strip rings are slidably sleeved on the outside of the extension columns 704.

[0026] like Figure 3 As shown, a positioning post 708 is coaxially fixed on the outer wall of the bottom of the base 2. The inner wall of the bottom of the slot 703 has a slot that matches the positioning post 708. The positioning post 708 is inserted into the corresponding hole inside the mounting base 1 to position the base 2, which facilitates the smooth progress of subsequent connection work. In addition, the positioning post 708 can also play a certain role in stabilizing the base 2 and prevent it from swaying left and right at will.

[0027] The motor 706 inside the base 2 is started, and its output end drives the drive frame 705 to start rotating. The drive frame 705 drives the insert plate 702, which is slidably inserted into the limit groove 701, to slide outward through the extension column 704. Finally, they abut against the inner circumference of the slot 703. The insert plate 702 can reinforce the base 2 again and ensure that it will not move up and down.

[0028] like Figure 1 As shown in Figure 2, a connecting seat 3 is rotatably connected to the inner wall of the top cavity of the base 2 via a bearing. A motor 1 is fixedly installed inside the base 2, and the motor 1 is coaxially fixed with the connecting seat 3. A large arm 4 is hinged to one side of the outer wall of the connecting seat 3. A motor 2 is installed inside the connecting seat 3, and the output end of the motor 2 is coaxially fixed with the rotation shaft of the large arm 4. A secondary arm 5 is hinged to one end of the top of the large arm 4. A motor 3 is fixedly installed inside the large arm 4, and the output end of the motor 3 is coaxially fixed with the rotation shaft of the secondary arm 5.

[0029] When the motor 1 in the upper chamber of the starting base 2 is started, the connecting base 3 can be driven to rotate horizontally. When the motor 2 inside the connecting base 3 is started, the main arm 4 can be driven to rotate longitudinally. Similarly, the motor 3 at the top of the main arm 4 can drive the auxiliary arm 5 to rotate longitudinally. With the cooperation of the connecting base 3, the main arm 4 and the auxiliary arm 5, the plasma spray gun at the end of the auxiliary arm 5 can better adapt to the spraying of the rudder compartment. When the external material is introduced into the spray gun, the spray gun generates a high-temperature plasma arc, which can melt the spraying material and accelerate the spraying onto the surface of the workpiece.

[0030] like Figure 2 and Figure 4 As shown, a rotating plate 6 is hinged to one end of the top of the auxiliary arm 5. A motor 5 is fixedly installed inside the auxiliary arm 5, and the output end of the motor 5 is coaxially fixed with the rotating shaft of the rotating plate 6. A clamping assembly 8 is installed on the outside of the rotating plate 6.

[0031] A horizontally mounted mounting plate 801 is fixedly connected to the outer wall of one end of the rotating plate 6. A horizontally mounted double-acting screw 802 is rotatably connected inside the mounting plate 801 via bearings. A movable plate 803 is threaded onto the threaded ends of both ends of the double-acting screw 802, and both movable plates 803 are in contact with the inner wall of the top wall of the mounting plate 801. A clamping plate 804 is fixedly connected to the end of the two movable plates 803 that are close to each other. The same plasma spray gun is placed between the two clamping plates 804. A protective frame 805 is fixedly installed on one side of the outer wall of the mounting plate 801, and a motor adapted to the double-acting screw 802 is installed inside the protective frame 805.

[0032] To replace or repair the plasma spray gun, start the motor four on the outer protective frame 805 of the mounting plate 801. The output of the motor four drives the bidirectional lead screw 802 to rotate. The movable plate 803, which is restricted to translation by the inner wall of the mounting plate 801, will move away from each other under the drive of the bidirectional lead screw 802. Subsequently, the two clamping plates 804 will also move away from the spray gun. At this time, the spray gun can be easily removed. The locking blocks on the outside of the clamping plates 804 can prevent the spray gun from moving randomly.

[0033] like Figure 3As shown, the edge of the card slot 703 and the top edge of several insert plates 702 are all provided with rounded corners 707, which makes the process of inserting the insert plate 702 into the card slot 703 more fault-tolerant and will not cause the operation to be obstructed due to slight position deviation.

[0034] This utility model provides a multi-axis robot for plasma spraying of a steering gear compartment, the specific working principle of which is as follows:

[0035] When the device is in operation, the base 2 of the robotic arm is placed on top of the mounting base 1. Then, the positioning pin 708 is inserted into the corresponding hole inside the mounting base 1 to position the base 2, facilitating subsequent connection work. The positioning pin 708 also provides a certain degree of stability, preventing the base 2 from swaying arbitrarily. Next, the motor 706 inside the base 2 is started, and its output end drives the drive frame 705 to rotate. The drive frame 705 drives the insert plate 702, which is slidably inserted into the limiting groove 701, to slide outward through the extension pin 704. Finally, they abut against the inner circumference of the slot 703. The insert plate 702 further reinforces the base 2 and ensures that it does not move up and down. Starting the first motor in the upper chamber of the base 2 causes the connecting seat 3 to rotate horizontally. Starting the second motor inside the connecting seat 3 causes the large arm 4 to rotate. Driven to rotate longitudinally, similarly, the motor three at the top of the main arm 4 can drive the auxiliary arm 5 to rotate longitudinally. With the cooperation of the connecting seat 3, the main arm 4 and the auxiliary arm 5, the plasma spray gun at the end of the auxiliary arm 5 can better adapt to the spraying of the rudder compartment. When the external material is introduced into the spray gun, the spray gun generates a high-temperature plasma arc, which can melt the spraying material and accelerate the spraying onto the surface of the workpiece. If the plasma spray gun needs to be replaced or repaired, start the motor four on the outer protective frame 805 of the mounting plate 801. The output end of the motor four drives the bidirectional lead screw 802 to rotate. The moving plate 803, which is restricted to translation by the inner wall of the mounting plate 801, will move away from each other under the drive of the bidirectional lead screw 802. Then the two clamping plates 804 will also move away from the spray gun. At this time, the spray gun can be easily removed. The locking block on the outside of the clamping plate 804 can prevent the spray gun from moving randomly.

[0036] 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.
