Description

TECHNICAL FIELD

[0001] The application relates to the technical field of radiator processing, and particularly relates to a positioning device for radiator processing and paint spraying. BACKGROUND

[0002] With the development of industrial manufacturing and automobile part processing technology, as an important automobile and electrical equipment part, a radiator often needs to be subjected to paint spraying treatment, so that the radiator must be accurately positioned during paint spraying processing, so as to ensure the quality and production efficiency of paint spraying.

[0003] Traditional radiator paint spraying positioning devices usually adopt mechanical clamps to fix the radiator, so as to ensure the stability and accuracy of the radiator during paint spraying. However, the traditional mechanical clamps are directly fixed on a platform, and the platform is usually fixed, and the adjustment of the clamps can only be locally adjusted on the platform. Therefore, when different sizes of radiators are processed, the platform space cannot be fully utilized, especially for small-sized radiators. The direct adjustment of the clamps on the platform to position the radiator can easily cause a gap between the radiator and the platform, so that paint is easily splashed on the platform or the clamp adjustment structure during paint spraying. Once the paint is splashed on these components, the normal work of the platform and the clamps can be affected, and the cleaning and maintenance workload is also increased.

[0004] Therefore, the application provides a positioning device for radiator processing and paint spraying to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The application provides a positioning device for radiator processing and paint spraying, and aims to solve the problems that the existing radiator paint spraying positioning device causes a gap when processing radiators of different sizes, causes paint splashing, affects the normal work of the equipment and increases the maintenance burden due to the fixed platform.

[0006] To achieve the above purpose, the application provides the following technical scheme: a positioning device for radiator processing and paint spraying, comprising a base, a support table arranged on the base and used for placing a radiator, and a magnetic attraction piece arranged on the support table and used for fixing and positioning the radiator.

[0007] The support table comprises a fixed plate fixedly arranged at the top end of the base, two moving plates arranged on the two sides of the support table and moving close to or away from each other, and an adjustment assembly arranged on the base and connected with the fixed plate and the moving plates and used for driving the two moving plates to move.

[0008] The magnetic attraction element is arranged on the fixed plate and the two movable plates; by combining the magnetic attraction element with the adjustable support table, different sizes and shapes of heat sinks can be positioned, improving the positioning flexibility; by arranging the support table composed of the fixed plate, the two movable plates and the adjusting assembly, the support table can be adjusted synchronously according to the size of the heat sink, so that the heat sink of different sizes can completely cover the surface of the support table, preventing paint from splashing on the support table, thereby not only protecting the structure and function of the support table, but also reducing the cleaning and maintenance requirements.

[0009] Preferably, in order to facilitate the adjustment of the size of the support table, the adjusting assembly comprises a lead screw arranged between the base and the fixed plate and rotatably connected at both ends to the base and the fixed plate, a threaded sleeve screwed on the lead screw, connecting rods arranged on both sides of the threaded sleeve and rotatably connected at both ends to the threaded sleeve and the bottom end of the movable plate, telescopic rods arranged on both sides of the movable plate and fixedly connected at both ends to the movable plate and the fixed plate, and a motor fixedly arranged in the base for driving the lead screw to rotate; the lead screw is driven to rotate by the motor, the threaded sleeve moves accordingly, and then the movable plate is driven to move through the connection of the connecting rods and the guidance of the telescopic rods, so as to realize the rapid adjustment of the size of the support table. This design simplifies the operation process and improves the accuracy and efficiency of the adjustment.

[0010] Preferably, in order to prevent paint from splashing on the lead screw, the width of the fixed plate is at least greater than the diameter of the threaded sleeve; since the width of the fixed plate is greater than the diameter of the threaded sleeve and the threaded sleeve is screwed on the outside of the lead screw, the fixed plate can shield the lead screw and other components, preventing paint from splashing on these components and reducing the workload of maintenance and cleaning, while also prolonging the service life of the equipment.

[0011] Preferably, in order to improve the support strength of the fixed plate, reinforcing rods for fixedly connecting with the base are fixedly arranged on both sides of the fixed plate away from the telescopic rods; the arrangement of the reinforcing rods enhances the connection between the fixed plate and the base, improves the stability and support strength of the fixed plate, and especially ensures the stability of the support table when bearing the weight of a large heat sink.

[0012] Preferably, in order to facilitate the magnetic attraction element to change the distance according to the size adjustment of the support table and adapt to different heat sinks, the magnetic attraction element comprises fixed magnets and movable magnets fixedly arranged at the top ends of the fixed plate and the two movable plates for magnetically attracting the heat sink; this design allows the distance between the movable magnets and the fixed magnets to change according to the size adjustment of the support table, so that different sizes of heat sinks can be closely fitted, ensuring the stability and reliability of the magnetic attraction effect.

[0013] Preferably, in order to ensure the magnetic attraction effect of the magnetic attraction element, the sizes of the fixed magnet and the moving magnet are consistent with the sizes of the fixed plate and the moving plate; such design ensures the maximization of the magnetic attraction area, thereby improving the magnetic attraction force, so that the radiator can be more firmly fixed on the positioning device to ensure the stability and coating quality during the paint spraying process.

[0014] The radiator processing and paint spraying positioning device can realize positioning of radiators of different sizes and shapes by combining the magnetic attraction element with the adjustable support table, thereby improving the positioning flexibility.

[0015] The radiator processing and paint spraying positioning device can ensure that radiators of different sizes can be completely covered on the surface of the support table by synchronously adjusting the support table according to the size of the radiator, thereby preventing paint from splashing on the support table, so as to not only protect the structure and function of the support table, but also reduce the need for cleaning and maintenance.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] The present embodiment provides a radiator processing and paint spraying positioning device, as shown in Figs. 1-3As shown, the positioning device comprises a base 1, a support table 2 arranged on the base 1 for placing the heat sink, and a magnetic attraction piece 3 arranged on the support table 2 for fixing and positioning the heat sink; the support table 2 comprises a fixed plate 21 fixedly arranged at the top end of the base 1, two moving plates 22 arranged on both sides of the support table 2 and movable towards or away from each other, and an adjusting assembly 23 arranged on the base 1 and connected with the fixed plate 21 and the moving plates 22 for driving the two moving plates 22 to move; the magnetic attraction piece 3 is arranged on the fixed plate 21 and the two moving plates 22.

[0025] In use, according to the size of the heat sink, the two moving plates 22 are driven to move towards or away from each other by the adjusting assembly 23 to adjust the size of the support table 2, so that the heat sink can be completely covered on the support table 2; at the same time, since the magnetic attraction piece 3 is arranged on the moving plates 22 and the fixed plate 21, when the distance between the fixed plate 21 and the moving plates 22 is adjusted, the distance between the magnetic attraction piece 3 on the fixed plate 21 and the adjusting assembly 23 is also adjusted synchronously, so as to be suitable for magnetic attraction fixing of heat sinks of different sizes; when painting is needed, the heat sink to be painted is placed on the fixed plate 21 and the moving plates 22 after adjustment, and it is ensured that the bottom surface of the heat sink is in contact with the top surface of the fixed plate 21 and the two moving plates 22; in this process, the magnetic attraction piece 3 on the fixed plate 21 and the moving plates 22 magnetically attracts and fixes the heat sink, so as to ensure that the heat sink does not move or tilt during painting.

[0026] Specifically, the adjusting assembly 23 comprises a lead screw 231 arranged between the base 1 and the fixed plate 21 and rotatably connected at both ends to the base 1 and the fixed plate 21, a threaded sleeve 232 screwed on the lead screw 231, a connecting rod 233 arranged on both sides of the threaded sleeve 232 and rotatably connected at both ends to the threaded sleeve 232 and the bottom end of the moving plate 22, an extension rod 234 arranged on both sides of the moving plate 22 and fixedly connected at both ends to the moving plate 22 and the fixed plate 21, and a motor 235 fixedly arranged in the base 1 for driving the lead screw 231 to rotate.

[0027] When it is necessary to adjust the size of the support table 2 to adapt to heat sinks of different sizes, the motor 235 is started to drive the rotation of the lead screw 231; since the threaded sleeve 232 is threadedly connected with the lead screw 231, as the lead screw 231 rotates, it causes the threaded sleeve 232 to move up and down on the lead screw 231; then, the movement of the threaded sleeve 232 drives the swinging of the connecting rod 233; since one end of the connecting rod 233 is rotatably connected with the threaded sleeve 232, when the threaded sleeve 232 moves, the connecting rod 233 pushes or pulls the moving plate 22 to move relative to the fixed plate 21 under the extension and retraction guiding action of the extension rod 234, so that the two moving plates 22 move towards or away from each other, thereby realizing the adjustment of the size of the support table 2.

[0028] In order to prevent paint from spraying on the screw rod 231, the width of the fixed plate 21 is at least greater than the diameter of the threaded sleeve 232; because the width of the fixed plate 21 is greater than the diameter of the threaded sleeve 232, and the threaded sleeve 232 is screwed outside the screw rod 231, the fixed plate 21 can shield the screw rod 231 and other components, preventing paint from spraying on these components, reducing the workload of maintenance and cleaning, and prolonging the service life of the equipment.

[0029] In addition, in order to improve the support strength of the fixed plate 21, the two sides of the fixed plate 21 away from the telescopic rod 234 are fixedly provided with a reinforcing rod 211 for fixed connection with the base 1; the reinforcing rod 211 enhances the connection between the fixed plate 21 and the base 1, improves the stability and support strength of the fixed plate 21, and ensures the stability of the support table 2 when bearing a large weight of the heat sink.

[0030] Further, the magnetic attraction member 3 includes fixedly arranged fixed magnets 31 and moving magnets 32 respectively at the top of the fixed plate 21 and the two moving plates 22 for magnetically attracting the heat sink;

[0031] When the two moving plates 22 are driven to move close to or away from the fixed plate 21 by the adjusting assembly 23, at this time, the moving magnets 32 connected to the two moving plates 22 also move synchronously, and the fixed magnets 31 are fixed on the fixed plate 21, so when the distance between the two moving plates 22 and the fixed plate 21 is adjusted, the distance between the two moving magnets 32 and the fixed magnets 31 will also change, thereby adapting to heat sinks of different sizes and ensuring that the heat sink can be firmly attracted on the support table 2.

[0032] It can be understood that in order to ensure the magnetic attraction effect of the magnetic attraction member 3, the size of the fixed magnets 31 and the moving magnets 32 is consistent with the size of the fixed plate 21 and the moving plate 22; in this way, the maximum magnetic attraction area can be ensured, thereby improving the magnetic attraction force, so that the heat sink can be more firmly fixed on the positioning device to ensure the stability and coating quality during the paint spraying process.

[0033] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
