Description

Technical Field

[0001] This utility model relates to the field of bushing outer tube production technology, and in particular to a bushing outer tube gluing machine. Background Technology

[0002] A bushing, often simply called a "shroud" or "sleeve," is a common mechanical part. It is a hollow cylindrical sleeve, typically pressed into a hole in a larger component (such as a housing, bracket, or connecting rod). During equipment operation, continuous vibration and impact occur. Under long-term alternating loads, a pure interference fit will cause slight creep and stress relaxation in the metal, leading to a gradual decrease in the fitting pressure. Eventually, this can cause fretting or even complete loosening and detachment between the bushing and the mounting hole. Once loosened, abnormal noise and greater wear will occur. The adhesive applied to the outer wall of the bushing fills all the microscopic gaps between them. In an oxygen-deficient environment, the adhesive solidifies to form a tough plastic layer, generating extremely strong adhesion that firmly "bonds" the bushing to the mounting hole, effectively resisting vibration and impact and preventing any minor loosening.

[0003] Nowadays, most adhesive application is done using adhesive application machines to replace manual labor. These machines automatically, accurately, and efficiently apply a specified amount of adhesive to the outer wall of the bushing (or the inner wall of the mounting hole). However, during the processing, the outer tube of the bushing is fitted onto the positioning rod, and the outer tube may shake during adhesive application, which can easily lead to uneven application and affect the performance. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art that when the outer tube of the bushing is sleeved on the positioning rod during the processing, the outer tube of the bushing will shake, which will easily lead to uneven coating and affect the effect of use. Therefore, a bushing outer tube glue coating machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bushing outer tube glue applicator includes a base, a protective cover fixedly connected to the top of the base, a rotating disk rotatably connected to the top of the base, and further includes; A fixing assembly, the fixing assembly including a threaded rod rotatably connected to a rotating disk, a threaded sleeve threadedly connected to the outside of the threaded rod, a rotating plate rotatably connected to the outside of the threaded sleeve, a clamping plate rotatably connected to the end of the rotating plate away from the threaded sleeve, and balls disposed outside the clamping plate. The processing assembly includes a cleaning bracket, an adhesive application bracket, and a detection bracket fixedly connected to the top of the base. A cleaning brush is rotatably connected inside the cleaning bracket, an adhesive dispensing head is fixedly connected inside the adhesive application bracket, and a coating thickness detector is installed inside the detection bracket.

[0006] As a preferred technical solution of this application, a feeding window is provided on one side of the outer side of the protective cover, and a discharging window is provided on the other side of the outer side of the protective cover.

[0007] As a preferred technical solution of this application, a plurality of rotating plates are provided, and the rotating plates are symmetrically arranged. On the other side, a fixed sleeve is rotatably connected to the end of the rotating plate away from the clamping plate, and one end of the fixed sleeve is fixedly connected to the outside of the rotating disk.

[0008] As a preferred technical solution of this application, a vacuum head is fixedly connected to one side of the cleaning bracket, the vacuum head is located on one side of the cleaning brush, the lower end of the vacuum head is connected to a vacuum cleaner through a pipe, and an electric heater is fixedly connected to one side of the cleaning bracket.

[0009] As a preferred technical solution of this application, auxiliary rollers are rotatably connected to both sides of the inner side of the glue application bracket, the glue outlet is located on the adjacent side of the auxiliary rollers, and the lower end of the glue outlet is connected to a paint tank through a pipe.

[0010] As a preferred technical solution of this application, a drying bracket is fixedly connected to the outside of the adhesive application bracket, the drying bracket is disposed between the adhesive application bracket and the testing bracket, and a dryer is disposed inside the drying bracket.

[0011] As a preferred technical solution of this application, an electric push rod is fixedly connected to one side of the inner side of the detection bracket, and the top of the coating thickness detector is fixedly connected to the output end of the electric push rod.

[0012] As a preferred technical solution of this application, a nozzle is fixedly connected to the other side of the inside of the detection bracket, and the input end of the nozzle is connected to a storage box through a pipe. The storage box is set inside the base.

[0013] Compared with the prior art, this utility model provides a bushing outer tube glue coating machine, which has the following beneficial effects: 1. By using a fixed assembly, the outer tube is fitted onto the outside of the threaded rod. An internal motor drives the threaded rod to rotate, which in turn drives the threaded sleeve to move through the threaded groove, causing the rotating plate to rotate. This pushes the clamping plate to support the pipe, reducing pipe sway. During coating, the auxiliary rollers rotate the pipe through friction. The ball bearings ensure smooth rotation of the pipe outside the clamping plate, improving processing stability.

[0014] 2. Through the set cleaning bracket, drying bracket and inspection bracket, the workpiece is first cleaned by the cleaning brush to keep it clean, and then the workpiece is heated by the electric heater to maintain the temperature of the workpiece, making it easier to apply glue. Then the workpiece enters the glue application bracket to apply glue. After the glue application is completed, it enters the interior of the drying bracket to dry and keep the coating stable. Then the coating thickness is inspected by the coating thickness detector, which can complete the inspection and easily eliminate unqualified products. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0018] Reference Figure 1-6A bushing outer tube gluing machine includes a base 1, a protective cover 2 fixedly connected to the top of the base 1, and a rotating disk 3 rotatably connected to the top of the base 1. It also includes a fixing component and a processing component. The fixing component includes a threaded rod 301 rotatably connected to the rotating disk 3, a threaded sleeve 302 threadedly connected to the outside of the threaded rod 301, a rotating plate 304 rotatably connected to the outside of the threaded sleeve 302, a clamping plate 305 rotatably connected to the end of the rotating plate 304 away from the threaded sleeve 302, and ball bearings 306 disposed outside the clamping plate 305. The processing component includes a cleaning bracket fixedly connected to the top of the base 1. 4. The adhesive application bracket 5 and the detection bracket 6 are provided. The cleaning bracket 4 is rotatably connected to the inside of the cleaning bracket 4. The adhesive application bracket 5 is fixedly connected to the inside of the adhesive application bracket 5. The detection bracket 6 is equipped with a coating thickness detector 602. The protective cover 2 has a feeding window 201 on one side of its exterior and a discharging window 202 on the other side of its exterior. Several rotating plates 304 are provided and are symmetrically arranged. The end of the rotating plate 304 away from the clamping plate 305 is rotatably connected to a fixing sleeve 303. One end of the fixing sleeve 303 is fixedly connected to the outside of the rotating disk 3.

[0019] The bushing to be processed is placed on the rotating disk 3 through the feed window 201. The rotating threaded rod 301 drives the threaded sleeve 302 to move linearly, which in turn drives the clamping plates 305 on both sides to move in opposite directions through the rotating plate 304. The ball bearings 306 on the surface of the clamping plate 305 flexibly fasten the outer tube of bushings of different sizes, avoiding scratching the surface of the workpiece. At the same time, the ball bearings 306 do not obstruct the workpiece when it rotates, which facilitates the rotation of the workpiece while maintaining its stability. After fastening, the rotating disk 3 rotates intermittently, sequentially sending the workpiece into the cleaning bracket 4, the glue application bracket 5 and the inspection bracket 6. The cleaning brush 401 rotates at high speed to remove the oxide layer and impurities on the surface of the outer tube to ensure glue application. For adhesion, the dispensing head 502 then applies a quantitative coating, and finally the coating thickness is measured non-contactly by the coating thickness detector 602 to ensure coating uniformity and quality consistency. When the threaded rod 301 drives the threaded sleeve 302 on one side to move, the symmetrically distributed rotating plates 304 can synchronously drive the clamping plates 305 on both sides to achieve precise opposite or reverse movement, ensuring that the clamping force is evenly distributed on both sides of the bushing outer tube, avoiding workpiece displacement or clamping instability that may be caused by unilateral force. The fixed sleeve 303 is fixedly connected to the outside of the rotating disk 3 to maintain the position of the clamping plate 305, reducing the rotation of the threaded rod 301 and maintaining clamping stability.

[0020] Reference Figure 4 , Figure 5 and Figure 6A bushing outer tube gluing machine further includes a dust suction head 402 fixedly connected to one side of the cleaning bracket 4, the dust suction head 402 being located on one side of the cleaning brush 401, the lower end of the dust suction head 402 being connected to a vacuum cleaner 403 via a pipe, and an electric heater 404 fixedly connected to one side of the cleaning bracket 4; auxiliary rollers 501 are rotatably connected to both sides of the inside of the gluing bracket 5, and a glue outlet 502 is located on the adjacent side of the auxiliary rollers 501, the lower end of the glue outlet 502 being connected to a paint tank 503 via a pipe; a drying bracket 504 is fixedly connected to the outside of the gluing bracket 5, the drying bracket 504 being located between the gluing bracket 5 and the detection bracket 6, and a dryer 505 is installed inside the drying bracket 504.

[0021] The vacuum head 402, in conjunction with the vacuum cleaner 403, can immediately remove dust particles generated after the cleaning brush 401 removes surface impurities, avoiding secondary pollution. The electric heater 404 can preheat and dry the cleaned bushing surface, ensuring that the surface is free of moisture and the adhesive has better fluidity during subsequent coating. The auxiliary roller 501 can stably support and guide the bushing rotation during coating, ensuring the uniformity of coating by the glue dispensing head 502. The dryer 505 can pre-cur the adhesive layer immediately after coating, avoiding contact damage during transfer to the inspection station. By integrating vacuuming, preheating, coating, and pre-drying functions, a complete pre-treatment-processing-post-treatment production line is formed, significantly improving the stability of coating quality and production efficiency, while effectively controlling pollutant emissions during the production process. It should be noted that the threaded rod 301, the cleaning brush 401, and one of the auxiliary rollers 501 are all equipped with motors that can drive them to rotate, and the tops of the paint tank 503 and the storage tank 603 are fixedly connected to pump bodies.

[0022] Among them, an electric push rod 601 is fixedly connected to one side of the inside of the testing bracket 6, and the top of the coating thickness detector 602 is fixedly connected to the output end of the electric push rod 601; a nozzle 604 is fixedly connected to the other side of the inside of the testing bracket 6, and the input end of the nozzle 604 is connected to a storage box 603 through a pipe. The storage box 603 is set inside the base 1.

[0023] The electric push rod 601 can precisely control the lifting and moving of the coating thickness detector 602, enabling smooth approach and departure during measurement, avoiding collisions with workpieces and adapting to bushings of different heights. At the same time, the electric push rod 601 allows the measuring instrument to be raised to a safe position during non-working periods, preventing dust pollution and mechanical damage. The nozzle 604 and the storage box 603 are connected to form a marking system. When the coating thickness is found to be unqualified, colored marking liquid can be automatically sprayed to instantly mark the defective product. The integrated detection and marking functions realize the seamless automation of quality judgment and product sorting, greatly improving the identification efficiency and sorting speed of unqualified products, and avoiding misjudgments and omissions in manual inspection.

[0024] Specifically, in use, the bushing to be processed is placed outside the threaded rod 301 on the rotating disk 3 through the feeding window 201. Then, the motor is started to drive the threaded rod 301 to rotate, which in turn drives the threaded sleeve 302 to move linearly. When the threaded sleeve 302 moves towards the fixed sleeve 303, it pushes the rotating plate 304 to rotate, and one end of the clamping plate 305 is squeezed and lifted to support the workpiece. Then, the rotating disk 3 is started to drive the workpiece into the cleaning bracket 4. The motor of the cleaning brush 401 is then started to rotate. The cleaning brush 401 rotates at high speed to remove the oxide layer and impurities on the surface of the outer tube to ensure the adhesion of the adhesive. During the cleaning process, the vacuum cleaner 403 is turned on in conjunction with the vacuum head 402 to immediately suck up the dust particles generated after the cleaning brush 401 removes surface impurities, avoiding secondary pollution. Then, the electric heater 404 is used to preheat and dry the surface of the cleaned bushing. To ensure the surface is free of moisture and the adhesive has better fluidity during subsequent coating, the rotating disc 3 carries the workpiece into the coating holder 5. The coating from the coating tank 503 is pumped onto the workpiece through the dispensing head 502 by the pump. At the same time, the motor of the auxiliary roller 501 is started to rotate, which in turn drives the workpiece to rotate through friction, maintaining the uniformity of the coating. After coating, the workpiece enters the drying holder 504, and then the dryer 505 is turned on. The dryer 505 consists of a heater and a fan. The fan blows heat evenly onto the workpiece to accelerate the drying speed. The workpiece is then carried into the inspection holder 6. The electric push rod 601 is started to control the lifting and moving of the coating thickness detector 602. After approaching the workpiece, the coating of the workpiece is inspected using ultrasound and laser. If a defective workpiece is detected, the nozzle 604 can automatically spray colored marking liquid to instantly mark the defective product for easy processing.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
