Description

Technical Field

[0001] This utility model belongs to the field of motor parts processing technology, and in particular relates to a device that can realize automatic calibration of paint drip nozzles. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It mainly includes electric motors and generators. An electric motor is a device that converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy. When processing the rotor of an electric motor, a paint dripping nozzle is needed to apply paint to the rotor.

[0003] However, most existing paint drip nozzles are fixed and require manual adjustment later. They cannot be automatically calibrated according to the size of the motor rotor. Furthermore, the manual adjustment method cannot keep the paint dripping position of the nozzle consistent, which directly affects the paint dripping quality. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a device that can automatically calibrate the paint dripping nozzle, solving the problem that it is impossible to quickly and automatically calibrate the position of the paint dripping nozzle according to the size of the motor rotor, and that manual control cannot keep the paint dripping position of the nozzle consistent, which directly affects the paint dripping quality.

[0005] This utility model is implemented as follows: a device for automatically calibrating paint drip nozzles includes a placement frame and a placement plate fixed inside the placement frame. Multiple sets of fixing sleeves that cooperate with a motor rotor are rotatably mounted on the placement plate in the left-right direction. A top frame is provided at the top of the inner cavity of the placement frame. A square frame is slidably arranged inside the top frame. Multiple sets of fixing brackets are fixed in the square frame in the left-right direction. Multiple sets of electric slide rails with one side fixed to the fixing bracket are inserted in each set of square frames in the left-right direction. The electric slide rails have built-in positive and negative threaded rods. A moving block is symmetrically slidably arranged on each set of fixing brackets in the front-back direction. A drip nozzle is inserted on each set of moving blocks. A connecting seat with one end fixed to the moving block is symmetrically arranged on the electric slide rails in the front-back direction via threaded sleeves. A small industrial camera is fixed at the center of the bottom of the fixing bracket. A first cylinder is embedded in the back of the top frame, and the piston rod of the first cylinder is fixed to the square frame.

[0006] As a preferred embodiment of the present invention, a second cylinder is fixed to the bottom of the inner cavity of the placement frame, the piston rod of the second cylinder is fixed to a base frame, and auxiliary frames are symmetrically fixed on both sides of the top of the base frame in the front-back direction. One end of the auxiliary frame extends into the placement frame and is fixed to the top frame.

[0007] As a preferred embodiment of this utility model, each set of fixed sleeves has a small electric push rod fixed to the back of the top and bottom via a bracket. The piston rod of the small electric push rod passes through the fixed sleeve and is fixed with an arc-shaped pressure plate.

[0008] As a preferred embodiment of this utility model, each set of fixed sleeves has a docking shaft fixed to its back side, and a fixing screw is fixed to the end of the docking shaft away from the fixed sleeve.

[0009] As a preferred embodiment of this utility model, a fixing groove is provided on both sides of the inner cavity of the top frame, and a T-shaped slide bar is fixed on both sides of the square frame, with the side of the T-shaped slide bar away from the square frame slidingly disposed in the fixing groove.

[0010] As a preferred embodiment of this utility model, each set of auxiliary frames is fitted with a limiting sleeve, and one side of the limiting sleeve is fixed to the placement frame.

[0011] As a preferred embodiment of this invention, each set of drip nozzles is connected to an auxiliary telescopic pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a small electric push rod and an arc-shaped pressure plate to quickly press and position the end of the motor rotor, ensuring it is centered and aligned vertically with the drip nozzle. A small industrial camera allows for rapid detection of the motor rotor's position and the desired drip location. The electric slide rail, with its built-in positive and negative threaded rods, along with the connecting seat and moving block, enables adjacent drip nozzles to move synchronously in opposite directions. This allows for pre-defining the spacing between adjacent drip nozzles based on the dimensions of the desired drip location on the motor rotor. The first cylinder allows for free adjustment of the drip nozzle's position based on the desired drip location on the motor rotor. The entire drip nozzle adjustment process is electrically controlled, and the small industrial camera's observation allows for rapid automatic calibration of the drip nozzle position based on the motor rotor's dimensions. This avoids the inconsistency that manual adjustment can cause with manual dripping, effectively preventing compromised drip quality. Attached Figure Description

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, this utility model provides a device for automatic calibration of paint drip nozzles, including a placement frame 1, a controller on one side of the placement frame 1, and a placement plate 2 fixed inside the placement frame 1. Multiple sets of fixing sleeves 3, which cooperate with motor rotors, are rotatably mounted on the placement plate 2 in the left-right direction. A top frame 8 is provided at the top of the inner cavity of the placement frame 1. A square frame 10 is slidably arranged inside the top frame 8. Multiple sets of fixing brackets 13 are fixed in the square frame 10 in the left-right direction. Multiple sets of electric slide rails 14, one side of which is fixed to a fixing bracket 13, are inserted into each set of square frames 10 in the left-right direction. The electric slide rails 14 have built-in positive and negative threaded rods. Each set of fixing brackets 13 has symmetrically slidable parts in the front-back direction. The movable block 16 has a nozzle 18 inserted into it. The electric slide rail 14 has a connecting seat 15 fixed to the movable block 16 at one end through a threaded sleeve along the front-back direction. A small industrial camera 17 is fixed at the center of the bottom of the fixed frame 13. The back of the top frame 8 is embedded with a first cylinder 9 and the piston rod of the first cylinder 9 is fixed on the square frame 10. The design of this utility model makes the entire process of adjusting the position of the nozzle 18 electrically controlled. With the observation of the small industrial camera 17, the position of the paint nozzle 18 can be automatically calibrated quickly according to the size of the motor rotor. This avoids the inability of manual adjustment to keep the paint dripping position of the nozzle 18 consistent and can effectively avoid affecting the paint dripping quality.

[0024] As a preferred embodiment of this utility model, a second cylinder 11 is fixed to the bottom of the inner cavity of the placement frame 1, and a base frame 12 is fixed to the piston rod of the second cylinder 11. Auxiliary frames 20 are symmetrically fixed on both sides of the top of the base frame 12 in the front-back direction. One end of the auxiliary frame 20 passes through the placement frame 1 and is fixed to the top frame 8. The design of the second cylinder 11 can change the vertical position of the base frame 12 and the auxiliary frame 20, so that the vertical position of the nozzle 18 can be precisely changed according to the size of the motor rotor in order to improve the paint dripping effect.

[0025] As a preferred embodiment of this utility model, each set of fixed sleeves 3 has a small electric push rod 4 fixed to the back of the top and bottom by a bracket. The piston rod of the small electric push rod 4 passes through the fixed sleeve 3 and is fixed with an arc-shaped pressure plate 5. The design of the small electric push rod 4 and the arc-shaped pressure plate 5 can position the ends of motor rotors of different sizes and keep them in a centered state so that the drip nozzle 18 can be stably positioned above the motor rotor, thus improving the dripping effect.

[0026] As a preferred embodiment of this utility model, each set of fixing sleeves 3 has a docking shaft 6 fixed on its back. The end of the docking shaft 6 away from the fixing sleeve 3 is fixed with a fixing screw 7. The docking shaft 6 is designed to be quickly assembled with the pulley, and the fixing screw 7 is designed to be used in conjunction with the nut to quickly position the pulley so that the pulley can be driven to rotate by an external drive device, thereby driving the motor rotor to rotate. This facilitates complete paint dripping of the motor rotor and avoids paint dripping dead zones.

[0027] As a preferred embodiment of this utility model, the top frame 8 has a fixing groove on both sides of its inner cavity, and the square frame 10 has a T-shaped slide bar fixed on both sides. The side of the T-shaped slide bar away from the square frame 10 is slidably disposed in the fixing groove. The design of the fixing groove and the T-shaped slide bar facilitates the sliding limit of the top frame 8, which can effectively prevent the square frame 10 from detaching from the top frame 8 when moving, thus improving its movement stability.

[0028] As a preferred embodiment of this utility model, each set of auxiliary frames 20 is fitted with a limiting sleeve, and one side of the limiting sleeve is fixed to the placement frame 1. The design of the limiting sleeve can slide and limit the auxiliary frame 20, thereby improving the stability of the auxiliary frame 20 when it moves.

[0029] As a preferred embodiment of this utility model, each set of drip nozzles 18 is connected to an auxiliary telescopic pipe 19. The design of the auxiliary telescopic pipe 19 enables the drip nozzles 18 to be stably connected to the external paint supply pipe, making the drip nozzles 18 easier to assemble.

[0030] The working principle of this utility model:

[0031] refer to Figures 1 to 5The user first places the end of the motor rotor inside the fixed sleeve 3, and then activates the small electric push rod 4 via the controller. The small electric push rod 4 then moves the arc-shaped pressure plate 5. At this time, the two sets of synchronously moving arc-shaped pressure plates 5 can quickly press and position the end of the motor rotor, and can keep the end of the motor rotor in a centered state, maintaining a vertical plane with the drip nozzle 18. The small industrial camera 17 can quickly know the position of the motor rotor and the position where paint needs to be dripped. At this time, the user activates the electric slide rail 14 via the controller. The electric slide rail 14 can drive the two adjacent sets of connecting seats 15 to move in opposite directions through the built-in positive and negative threaded rods. Thus, with the cooperation of the moving block 16, the two adjacent sets of drip nozzles 18 can be driven to move in opposite directions synchronously until the required amount of paint is dripped onto the motor rotor. The size of the paint position predetermines the spacing between two adjacent sets of drip nozzles 18. At this time, the user activates the first cylinder 9 through the controller, which drives the top frame 8 and the drip nozzles 18 to move synchronously until the drip nozzles 18 are moved to the appropriate position according to the position on the motor rotor where the paint needs to be dripped. The design of the second cylinder 11 can change the vertical position of the top frame 8, thereby adjusting the spacing between the drip nozzles 18 and the motor rotor according to the size of the motor rotor. At the same time, the entire process of adjusting the position of the drip nozzles 18 is fully electronically controlled. With the observation of the small industrial camera 17, the position of the paint drip nozzles 18 can be automatically calibrated quickly according to the size of the motor rotor, avoiding the inability of manual adjustment to keep the paint dripping position of the drip nozzles 18 consistent, and effectively avoiding affecting the paint dripping quality.
