Description

Technical Field

[0001] This utility model belongs to the technical field of passivation treatment equipment, specifically a passivation treatment equipment for a variable diameter cable tray after plating. Background Technology

[0002] After electroplating, cable trays require passivation to form a solid, dense, and highly stable film on the plating. Passivation further improves the corrosion resistance of the plating and increases surface gloss and anti-fouling capabilities. During passivation, the cable trays need to be hoisted using a lifting mechanism and placed into the passivation tank for full contact with the passivation solution. Existing lifting mechanisms are not convenient for adjusting the hoisting spacing and cannot accommodate cable trays of different widths. Furthermore, the contact position between the existing lifting mechanism and the cable tray cannot be changed, preventing the contact points from participating in the passivation process and resulting in poor overall passivation. Therefore, this application proposes a variable-diameter passivation treatment device for cable trays after plating. Utility Model Content

The cable tray hoisting mechanism is located directly above the passivation tank. A controller is fixedly installed on the cable tray hoisting mechanism. One end of the controller is provided with a control handle connected to it via a cable. The cable tray hoisting mechanism consists of two hydraulic rods, a limiting rail, cylinder one, cylinder two, clamping assembly one, and clamping assembly two.

Clamping assembly one and clamping assembly two are respectively slidably connected to both ends of the bottom of the limiting rail. Clamping assembly one and clamping assembly two are respectively fixedly connected to cylinder one and cylinder two.

[0005] Both clamping assembly one and clamping assembly two consist of a slide, a spacing adjustment unit, a first clamping unit and a second clamping unit. The slide is slidably connected to the inside of the limiting rail, the spacing adjustment unit is fixedly connected to the bottom end of the slide, and the first clamping unit and the second clamping unit are respectively connected to the two ends of the bottom of the spacing adjustment unit.

[0022] 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.

[0023] Depend on Figures 1 to 5This invention discloses a passivation treatment device for a variable-diameter cable tray after plating, comprising a passivation tank 1 and a cable tray hoisting mechanism 2. The cable tray hoisting mechanism 2 is located directly above the passivation tank 1. A controller 3 is fixedly installed on the cable tray hoisting mechanism 2, and a control handle 4 connected to one end of the controller 3 via a cable is provided. The cable tray hoisting mechanism 2 consists of two hydraulic rods 5, a limit rail 6, a first cylinder 7, a second cylinder 8, a first clamping assembly 9, and a second clamping assembly 10. The hydraulic rods 5 are hoisting installation components. The structure includes a limiting rail 6 fixedly connected to the bottom end of a hydraulic rod 5; cylinders 7 and 8 respectively penetrating and connected to both ends of the limiting rail 6; clamping components 9 and 10 respectively slidably connected to both ends of the bottom of the limiting rail 6; and clamping components 9 and 10 respectively fixedly connected to cylinders 7 and 8. Both clamping components 9 and 10 consist of a slide block 11, a spacing adjustment unit 12, a first clamping unit 13, and a second clamping unit 14. A sliding connection is made inside the limiting rail 6. A spacing adjustment unit 12 is fixedly connected to the bottom end of the slide block 11. A first clamping unit 13 and a second clamping unit 14 are respectively connected to the two ends of the bottom of the spacing adjustment unit 12. The spacing adjustment unit 12 consists of a lead screw box 15, a servo motor 16, and a lead screw 17. The servo motor 16 is fixedly connected to one end of the lead screw box 15, and the lead screw 17 is rotatably connected inside the lead screw box 15 and fixedly connected to the output shaft of the servo motor 16. The lead screw 17 has two... The segmented symmetrical threaded structure consists of a first clamping unit 13 and a second clamping unit 14, each composed of a hanging plate 18, a first clamping arm 19, a second clamping arm 20, a third cylinder 21, and a fourth cylinder 22. The top of the hanging plate 18 is slidably connected to the inside of the screw box 15 and threadedly connected to the screw 17. The tops of the first clamping arm 19 and the second clamping arm 20 are both hinged to the hanging plate 18. The third cylinder 21 is hinged between the hanging plate 18 and the first clamping arm 19, and the fourth cylinder 22 is hinged between the hanging plate 18 and the second clamping arm 20.

[0024] When hoisting the cable tray, the distance between the first clamping unit 13 and the second clamping unit 14 is adjusted according to the width of the cable tray. During adjustment, the servo motor 16 drives the lead screw 17 to rotate, and the lead screw 17 drives the first clamping unit 13 and the second clamping unit 14 to move. Then, the cylinders 21 and 22 drive the first clamping arm 19 and the second clamping arm 20 to rotate respectively, so that the bottom of the first clamping arm 19 and the second clamping arm 20 separates. The two sets of first clamping arms 19 and second clamping arms 20 can clamp the two sides of the top of the cable tray respectively. Since the top of the cable tray is provided with a bent edge, it can form a limiting effect with the first clamping arm 19 and the second clamping arm 20, improving the stability of clamping. Qualitative analysis is performed, and then the hydraulic rod 5 extends to drive the cable tray into the passivation tank 1, so that the cable tray comes into contact with the passivation liquid, thereby achieving passivation treatment. Since the contact positions of the first clamping arm 19 and the second clamping arm 20 with the cable tray cannot participate in passivation, the clamping position can be changed through two adjustments. During the first adjustment, the clamping component 19 maintains the clamping force on the cable tray, while the clamping component 20 reduces the clamping force on the cable tray. Then, the cylinder 28 drives the clamping component 20 to move a certain distance, thereby changing the clamping position. During the second adjustment, the cylinder 17 drives the clamping component 19 to move a certain distance, so that the cable tray can fully contact the passivation liquid.

[0025] Both the first clamping arm 19 and the second clamping arm 20 are arc-shaped structures, which can be easily rotated and adjusted by cylinder three 21 and cylinder four 22.

[0026] The second clamping arm 20 is equipped with universal ball bearing 1 23 and universal ball bearing 24 at the end away from the hanging plate 18, which can reduce the friction with the cable tray and improve the mobility when changing position.

[0027] In operation, the cable tray lifting mechanism, consisting of two hydraulic rods, a limit rail, cylinder one, cylinder two, clamping assembly one, and clamping assembly two, enables the lifting of cable trays of different widths, thereby improving adaptability. During the passivation process, the contact position with the cable tray can be changed, allowing the cable tray to fully contact the passivation fluid, thus improving the overall passivation of the cable tray and avoiding passivation dead zones. By setting universal ball bearing one and universal ball bearing two, the contact flexibility with the cable tray can be improved when changing the contact position of the first and second clamping arms with the cable tray, reducing movement resistance and effectively reducing sliding friction.
