Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and more specifically, to an electrophoretic workpiece cleaning device. Background Technology

[0002] After electrophoresis, the next step for metal workpieces is usually surface cleaning, which involves spraying to remove residual electrophoretic solution from the workpiece surface. Traditional spray cleaning devices, due to the immobility of the spray nozzles and the need to ensure adequate spray coverage, require a large number of nozzles. However, this significantly reduces the spray pressure, thereby decreasing the cleaning effect and resulting in poor overall performance. Therefore, this invention proposes a workpiece cleaning device for electrophoresis. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electrophoretic workpiece cleaning device, which has the characteristics of wide spray coverage and thorough cleaning.

[0004] To solve the above-mentioned technical problems, the purpose of this invention is achieved as follows: The electrophoretic workpiece cleaning device of this invention includes an upper inner ring plate and an upper outer ring plate. A plurality of suspension rods arranged in a ring array around an axis are connected between the upper outer ring plate and the upper inner ring plate. The suspension rods extend radially along the upper inner ring plate or the upper outer ring plate.

[0005] A lower inner ring plate is provided directly below the upper inner ring plate. An inner compression spring is provided between the lower inner ring plate and the upper inner ring plate, with one end connected to the upper inner ring plate and the other end connected to the lower inner ring plate. A number of first pipeline fixing clips are provided on the outer side of the inner compression spring, which are arranged at intervals along its extension trajectory. The spring also includes a first nozzle bent into a spiral shape. The first nozzle is sequentially locked on all the first pipeline fixing clips. A number of first spray holes are arranged at intervals along its extension trajectory on the pipe wall of the first nozzle. The first spray holes spray away from the upper inner ring plate.

[0006] A lower outer ring plate is provided directly below the upper outer ring plate. An outer compression spring is provided between the lower outer ring plate and the upper outer ring plate, with one end connected to the upper outer ring plate and the other end connected to the lower outer ring plate. A plurality of second pipeline fixing clamps are provided on the inner side of the outer compression spring, which are arranged at intervals along its extension trajectory. The spring also includes a second nozzle bent into a spiral shape. The second nozzle is sequentially clamped on all the second pipeline fixing clamps. A plurality of second spray holes are arranged at intervals along its extension trajectory on the pipe wall of the second nozzle. The second spray holes face the upper inner ring plate to spray.

[0007] One end of the first nozzle and the second nozzle are both connected to a water supply source, and the other end is equipped with a plug.

[0008] It also includes a drive mechanism for controlling the lower inner ring plate and the lower outer ring plate to move up and down.

[0009] The present invention is further configured such that: the driving mechanism includes side frames arranged symmetrically front and rear, and a plurality of driving shafts arranged parallel to each other are rotatably connected between the side frames; a first cam is provided on the driving shaft below the lower inner ring plate, and a second cam is provided on the driving shaft below the lower outer ring plate; the second cam has the same shape and size as the first cam; the protrusion of the first cam faces upward, and the protrusion of the second cam faces downward; and a power mechanism for controlling its rotation is provided at one end of the driving shaft.

[0010] The present invention is further configured such that: the power mechanism includes a pulley assembly disposed between two adjacent drive shafts, the pulley assembly includes a first pulley, a second pulley, and a synchronous belt that is drive-connected to the first pulley and the second pulley, the first pulley is disposed on one drive shaft, the second pulley is disposed on another drive shaft, wherein one end of one of the drive shafts is drive-connected to a motor that controls its rotation.

[0011] The present invention is further configured such that: an inner guide rod with its lower end connected to the lower inner ring is slidably connected to the upper inner ring plate; and an outer guide rod with its lower end connected to the lower outer ring plate is slidably connected to the upper outer ring plate.

[0012] The present invention is further configured such that both the first pipeline fixing clamp and the second pipeline fixing clamp are U-shaped.

[0013] In summary, the present invention has the following beneficial effects: The electrophoretic workpiece cleaning device involved in the present invention fixes the inner and outer nozzles to elastic compression springs, so that the spray amplitude of the nozzle can be changed when the compression springs move up and down. In this way, while ensuring the spray pressure, the spray amplitude is increased, thereby improving the cleaning performance. The overall function is perfect and the practicality is strong.

[0022] See Figures 1 to 5 As shown, the electrophoretic workpiece cleaning device involved in this embodiment includes an upper inner ring plate 1 and an upper outer ring plate 2. A plurality of suspension rods 3 arranged in a ring array around the axis are connected between the upper outer ring plate 2 and the upper inner ring plate 1. The suspension rods 3 extend radially along the upper inner ring plate 1 or the upper outer ring plate 2.

[0023] A lower inner ring plate 4 is provided directly below the upper inner ring plate 1. An inner compression spring 5 is provided between the lower inner ring plate 4 and the upper inner ring plate 1, with one end connected to the upper inner ring plate and the other end connected to the lower inner ring plate. A plurality of first pipeline fixing clips 6 are provided on the outside of the inner compression spring 5, which are arranged at intervals along its extension trajectory. The spring also includes a first nozzle 7 bent into a spiral shape. The first nozzle 7 is sequentially clamped on all the first pipeline fixing clips 6. A plurality of first spray holes (not shown) are arranged at intervals along its extension trajectory on the pipe wall of the first nozzle 7. The first spray holes spray away from the upper inner ring plate.

[0024] A lower outer ring plate 8 is provided directly below the upper outer ring plate 2. An outer compression spring 9 is provided between the lower outer ring plate 8 and the upper outer ring plate 2, with one end connected to the upper outer ring plate and the other end connected to the lower outer ring plate. A plurality of second pipeline fixing clamps 10 are provided on the inner side of the outer compression spring 9, which are arranged at intervals along its extension trajectory. It also includes a second nozzle 11 bent into a spiral shape. The second nozzle 11 is sequentially locked on all the second pipeline fixing clamps 10. A plurality of second spray holes (not shown) are arranged at intervals along its extension trajectory on the pipe wall of the second nozzle 11. The second spray holes face the upper inner ring plate to spray.

[0025] One end of the first nozzle 7 and the second nozzle 11 are both connected to a water supply source (not shown), and the other end is provided with a plug (not shown);

[0026] It also includes a drive mechanism that controls the lower inner ring plate 4 and the lower outer ring plate 8 to move up and down.

[0027] Furthermore, the drive mechanism includes side frames 13 arranged symmetrically front and rear, and a plurality of drive shafts 14 arranged parallel to each other are rotatably connected between the side frames 13. A first cam 15 is provided on the drive shaft 14 below the lower inner ring plate 4, and a second cam 16 is provided on the drive shaft 14 below the lower outer ring plate 8. The second cam 16 has the same shape and size as the first cam 15. The protrusion of the first cam 15 faces upward, and the protrusion of the second cam 16 faces downward. One end of the drive shaft 14 is provided with a power mechanism to control its rotation.

[0028] Furthermore, the power mechanism includes a pulley assembly 17 disposed between two adjacent drive shafts 14. The pulley assembly 17 includes a first pulley 171, a second pulley 172, and a synchronous belt 173 that is driven to the first pulley and the second pulley. The first pulley 171 is disposed on one drive shaft, and the second pulley 172 is disposed on another drive shaft. One end of one of the drive shafts 14 is driven to a motor 20 that controls its rotation.

[0029] Furthermore, both the first pipeline fixing clamp 6 and the second pipeline fixing clamp 10 are U-shaped.

[0030] In this embodiment, the workpiece that has undergone electrophoresis is first hoisted into the annular area between the first nozzle 7 and the second nozzle 11. Then, cleaning fluid is pumped onto the first nozzle 7 and the second nozzle 11. At this time, the liquid flow from the nozzles on the first nozzle 7 and the second nozzle 11 washes the surface of the workpiece, achieving a local cleaning effect. Subsequently, the drive mechanism is activated, and the motor 20 operates, driving the mutually driven pulley assembly 17 until all drive shafts 14 rotate, which in turn drives the first cam 15 and the second cam 16 on the drive shaft 14 to rotate. When the protrusion of the first cam 15 moves upward and pushes the lower inner ring plate 4, the lower inner ring plate 4 moves upward, the inner compression spring 5 is compressed, and the nozzles on the first nozzle 7 move accordingly, increasing the spray amplitude. When the protrusion of the second cam 16 moves upward and pushes the lower outer ring plate 8, the lower outer ring plate 8 moves upward, the outer compression spring 9 is compressed, and the nozzles on the second nozzle 11 move accordingly, increasing the spray amplitude and achieving a thorough spraying effect.

[0031] Among them, the suspension rod 3 is used to connect the upper inner ring 1 and the lower inner ring 4, and both are used for lifting and installation.

[0032] Example 2

[0034] In this embodiment, the inner guide rod 18 serves to guide the lower inner ring 4 when it moves up and down relative to the upper inner ring 1; the outer guide rod 19 serves to guide the lower outer ring 8 when it moves up and down relative to the upper outer ring 2.

[0035] The electrophoretic workpiece cleaning device involved in this invention fixes the inner and outer nozzles to an elastic compression spring. When the compression spring moves up and down, it can change the spray amplitude of the nozzle, thereby increasing the spray amplitude while ensuring the spray pressure, thus improving the cleaning performance. The device has complete functions and strong practicality.
