Abstract
Description
Technical Field
[0001] This invention belongs to the field of powder zinc diffusion technology, specifically referring to a device for improving the temperature uniformity of the powder zinc diffusion process in power fittings. Background Technology
[0002] Powder zinc diffusion is a rust-preventive treatment process for steel parts. It involves mixing steel parts with a zinc diffusion agent in a sealed environment at 300-450℃. Through the diffusion effect of vaporized zinc powder, zinc penetrates the surface of the parts, forming a metallurgically bonded zinc-iron alloy protective layer. Electrical fittings are metal accessories that connect and assemble various devices in electrical systems, transmitting mechanical and electrical loads and providing some protection. Powder zinc diffusion is primarily used for steel parts, especially suitable for small, precision, or complex structural components, thus becoming an important method for rust prevention on the surface of electrical fittings. In powder zinc diffusion of electrical fittings, the fittings and zinc diffusion agent are placed simultaneously in a zinc diffusion device. To ensure sufficient contact between the complex electrical fittings and the zinc diffusion agent, and to maintain temperature uniformity during the zinc diffusion process, the device is usually driven to vibrate or rotate. However, under the influence of gravity, the zinc diffusion agent and the electrical fittings separate, causing the fittings to sink and accumulate at the bottom of the device. This results in uneven temperature distribution or insufficient contact between the fittings and the zinc diffusion agent during the powder zinc diffusion process.
[0003] Therefore, a device is needed to improve the temperature uniformity of the zinc diffusion process in power fitting powder to solve the above problems. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the present invention provides a device for improving the temperature uniformity of the powder zinc diffusion process of power fittings. The power fittings and zinc diffusion agent are uniformly mixed and placed in the inner shell. The power fittings are sank by vibration, and the sank power fittings are continuously transported into the inner shell by the outer rotating shell, so that the power fittings circulate from top to bottom in the zinc diffusion agent, thereby achieving temperature uniformity of the power fittings and full contact with the zinc diffusion agent during the powder zinc diffusion process.
[0005] The technical solution adopted by this invention is as follows: This invention proposes a device for improving the temperature uniformity of the zinc infiltration process in power fittings, comprising a base, a lower mounting plate on the upper wall of the base, an upper mounting plate hinged to the upper wall of the lower mounting plate, a rotating tube penetrating the upper part of the upper mounting plate, an outer rotating shell fixedly mounted at the end of the rotating tube, a rotating shaft rotatably mounted inside the rotating tube, the rotating shaft penetrating the outer rotating shell and the rotating tube, an inner shell rotatably mounted inside the outer rotating shell, the upper part of the inner shell having a notch, a discharge port on the outer wall of the inner shell opposite to the notch, and a center of one side of the inner shell fixedly mounted to the inner end of the rotating shaft, the inner shell containing... The device includes a heating assembly, a uniform feeding assembly at one end of the notch in the inner shell, and a grid plate at equal intervals around the axis on the inner wall of the outer rotating shell. The grid plate is located between the outer rotating shell and the inner shell along the radial direction of the outer rotating shell. An end cap is rotatably provided at the end of the outer rotating shell. The end cap is adjusted and mounted on the side wall of the upper mounting plate. A filter discharge assembly is provided on the lower part of the outer wall of the end cap. A rotation drive assembly is provided on the upper mounting plate and the outer rotating shell. An intermittent vibration assembly is provided on the upper mounting plate, the rotating tube, and the rotating shaft. A hydraulic rod is provided between the upper mounting plate and the base, with both ends of the hydraulic rod hinged to the upper mounting plate and the base, respectively.
[0006] Furthermore, the intermittent vibration assembly includes a telescopic plate, a connecting rod, a tension spring, a placement plate, a push rod, and a wheel. The side wall of the upper mounting plate has a through-hole groove, which is arc-shaped and coaxial with the rotating tube. The wheel is mounted on the rotating tube, and its outer wall has peaks and valleys arranged in an array around its axis. The peaks and valleys are spaced apart and smoothly connected. The upper end of the telescopic plate is fixed to the end of the rotating shaft. One end of the push rod is located on the lower inner side wall of the telescopic plate, passing through the through-hole groove. The other end of the push rod intermittently contacts the peaks and valleys of the wheel. The connecting rod is located on the lower outer side wall of the telescopic plate, and the placement plate is located on the outer side wall of the upper mounting plate. Both ends of the tension spring are respectively located on the connecting rod and the placement plate.
[0007] Furthermore, the filter discharge assembly includes a sealing baffle, a baffle rod, and a locking assembly. The outer wall of the end cap is provided with a sliding groove, which is arc-shaped. The two edges of the sliding groove are provided with slots, which are the same shape as the sliding groove. A filter window is provided through the lower part of the outer wall of the end cap. The filter window is arc-shaped and located within the sliding groove. The baffle rod is evenly spaced within the filter window around the axis. The sealing baffle is arc-shaped and slides within the sliding groove. The two edges of the sealing baffle are located within the slots. The locking assembly is located at one end of the sealing baffle.
[0008] Furthermore, the heating assembly includes a main heating rod and a heat-conducting rod. The two ends of the main heating rod are located at the center of the two inner side walls of the inner shell, and multiple heat-conducting rods are provided on the lower part of the outer wall of the main heating rod.
[0009] Furthermore, the uniform feeding assembly includes a feeding plate, a connecting shaft, and a torsion spring. The inner wall of one end of the notch in the inner housing is symmetrically provided with mounting holes. The two ends of the feeding plate are symmetrically provided with connecting shafts. The feeding plate is rotatably mounted within the mounting holes via the connecting shafts. The torsion spring is sleeved on the connecting shaft, with its two ends respectively located on the side wall of the feeding plate and the bottom wall of the mounting hole. Initially, the end of the feeding plate is inclined towards the interior of the inner housing. When the power fitting slides down from the feeding plate, the feeding plate automatically rotates downwards, thus ensuring that the power fitting does not always fall at the same position on the zinc plating agent inside the inner housing.
[0010] Furthermore, the rotary drive assembly includes a gear ring, a gear, a reducer, a linkage shaft, and a motor. The reducer is located on one side wall of the upper mounting plate, and the motor is located on the other side wall of the upper mounting plate. The output shaft of the motor passes through the side wall of the upper mounting plate and is connected to the input shaft of the reducer. The linkage shaft is connected to the output shaft of the reducer. The gear is located at the end of the linkage shaft, and the gear ring is located on the outer wall of the end of the outer rotating housing. The gear ring meshes with the gear.
[0011] Furthermore, the locking assembly includes a connecting post, a stop, a compression spring, a locking plate, and a locking shaft. A locking hole one is provided on the outer side of one end of the groove on the outer wall of the end cap, and a locking hole two is provided at the end of the groove near the filter window. The connecting post is located on the upper wall of one end of the sealing baffle. The stop is located at the upper end of the connecting post. One end of the locking plate is slidably mounted on the connecting post. The compression spring is sleeved on the connecting post, with its two ends respectively located on the stop and the locking plate. One end of the locking shaft is located at the other end of the locking plate.
[0012] Furthermore, the adjustment frame includes a boss, a second hydraulic rod, and a support plate. The boss is symmetrically arranged at the edge of the end cover, the support plate is symmetrically arranged on both sides of the upper mounting plate, and the two ends of the second hydraulic rod are respectively arranged on the boss and the support plate.
[0013] Furthermore, the end face of the end cap is provided with a rotating groove, and universal balls are arranged in an array around the axis in the rotating groove, and the end face of the outer rotating shell is rotatably disposed in the rotating groove.
[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The rotary drive assembly drives the outer rotating shell and the grid plate to rotate. The zinc diffusion agent and the power fittings fall from the feeding port at the bottom of the inner shell into the space between the grid plates. As the grid plates rotate, the zinc diffusion agent leaks down from the grid plates, while the power fittings are conveyed to the gap in the inner shell along with the grid plates. The power fittings fall into the inner shell through the uniform feeding assembly, thus forming a circulation between the inner shell and the outer rotating shell. This prevents the power fittings from sinking and accumulating at the bottom of the inner shell, which would cause uneven temperature and insufficient contact with the zinc diffusion agent during the powder zinc diffusion process. 2. During the circulation of the power fittings driven by the outer rotating shell and the fence plate, the outer rotating shell drives the rotating tube to rotate, and the rotating tube drives the wheel to rotate. The peaks and valleys on the wheel intermittently contact the push rod. Under the action of the tension spring, the push rod is continuously pushed up and pulled back. The telescopic plate and the rotating shaft swing back and forth. The rotating shaft drives the inner shell to swing, thereby generating vibration on the zinc-diffusion agent and the power fittings in the inner shell, causing the power fittings to sink in the zinc-diffusion agent. During this process, the zinc-diffusion agent and the power fittings are in full contact. 3. The hydraulic rod can adjust the angle of the upper mounting plate. When the upper mounting plate is tilted upward, it is convenient to add the zinc plating agent and electrical fittings into the inner housing. When the upper mounting plate is tilted downward, it is convenient to separate the zinc plating agent and electrical fittings and to remove the zinc-plated electrical fittings. 4. In the filter discharge assembly, the sealing baffle slides upward, the filter window opens, the upper mounting plate tilts downward, the motor is turned on, the outer rotating housing and the grid plate rotate, and the zinc diffusion agent can leak out between the baffle rods, separating the zinc diffusion agent from the power fittings. Adjust the hydraulic rod two, the end cover separates from the outer rotating housing, and the power fittings can be discharged from the end cover and the outer rotating housing.

[0020] like Figures 1-4 As shown, this invention proposes a device for improving the temperature uniformity of the zinc infiltration process in power fittings powder, comprising a base 1, a lower mounting plate 2 on the upper wall of the base 1, an upper mounting plate 3 hinged to the upper wall of the lower mounting plate 2, a rotating tube 4 penetrating the upper part of the upper mounting plate 3, an outer rotating shell 5 fixedly mounted at the end of the rotating tube 4, a rotating shaft 6 rotatably mounted inside the rotating tube 4, the rotating shaft 6 penetrating the outer rotating shell 5 and the rotating tube 4, an inner shell 7 rotatably mounted inside the outer rotating shell 5, a notch 8 at the upper part of the inner shell 7, a discharge port 9 opposite to the notch 8 on the outer wall of the inner shell 7, a heating component 10 fixedly mounted at the center of one side of the inner shell 7 to the inner end of the rotating shaft 6, and the inner shell 7 containing the heating component 10. A uniform feeding component 11 is provided at one end of the notch 8. A grid plate 12 is provided at equal intervals around the axis on the inner wall of the outer rotating shell 5. The grid plate 12 is located between the outer rotating shell 5 and the inner shell 7 along the radial direction of the outer rotating shell 5. An end cover 13 is provided at the end of the outer rotating shell 5. The end cover 13 is provided on the side wall of the upper mounting plate 3 through the adjustment bracket 52. A filter discharge component 14 is provided at the lower part of the outer wall of the end cover 13. A rotation drive component 15 is provided on the upper mounting plate 3 and the outer rotating shell 5. An intermittent vibration component 16 is provided on the upper mounting plate 3, the rotating tube 4 and the rotating shaft 6. A hydraulic rod 44 is provided between the upper mounting plate 3 and the base 1. The two ends of the hydraulic rod 44 are respectively hinged to the upper mounting plate 3 and the base 1.
[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the intermittent vibration assembly 16 includes a telescopic plate 18, a connecting rod 19, a tension spring 20, a placement plate 21, a push rod 22, and a wheel 23. The side wall of the upper mounting plate 3 has a through-hole groove 24, which is arc-shaped and coaxial with the rotating tube 4. The wheel 23 is mounted on the rotating tube 4. The outer wall of the wheel 23 has peaks 25 and valleys 26 arranged in an array around its axis, spaced apart and smoothly connected. The upper end of the telescopic plate 18 is fixed to the end of the rotating shaft 6. One end of the push rod 22 is located on the inner side wall of the lower end of the telescopic plate 18, passing through the opening groove 24. The other end of the push rod 22 intermittently contacts the peaks 25 and valleys 26 of the wheel 23. The connecting rod... 19 is located on the lower outer wall of the telescopic plate 18, and the placement plate 21 is located on the outer wall of the upper mounting plate 3. The two ends of the tension spring 20 are respectively located on the connecting rod 19 and the placement plate 21. The push rod 22 cyclically contacts the peak 25 and the valley 26 of the wheel 23. As the push rod 22 gradually moves from the valley 26 to the peak 25, the push rod 22 is pushed upward. When it moves from the peak 25 to the valley 26, the push rod 22 is pulled back to the valley 26. Since the peak 25 and the valley 26 are smoothly connected, the push rod 22 will not collide hard with the peak 25 and the valley 26. The outer radius of the opening groove 24 is greater than the sum of the radius of the peak 25 of the wheel 23 and the diameter of the push rod 22. When the push rod 22 moves to the peak 25, the opening groove 24 will not interfere with the push rod 22.
[0022] like Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the filter discharge assembly 14 includes a sealing baffle 27, a baffle rod 28, and a locking assembly 29. The outer wall of the end cap 13 is provided with a sliding groove 30, which is arc-shaped. The two edges of the sliding groove 30 are provided with slots 31, which are the same shape as the sliding groove 30. The lower part of the outer wall of the end cap 13 is provided with a filter window 32, which is arc-shaped and located in the sliding groove 30. The baffle rod 28 is evenly spaced around the axis in the filter window 32. The sealing baffle 27 is arc-shaped and slides in the sliding groove 30. The two edges of the sealing baffle 27 are in the slots 31. The locking assembly 29 is located at one end of the sealing baffle 27.
[0023] like Figure 1 , Figure 3 and Figure 6As shown, the heating assembly 10 includes a main heating rod 33 and a heat-conducting rod 34. The two ends of the main heating rod 33 are located at the center of the two inner side walls of the inner shell 7. The lower part of the outer wall of the main heating rod 33 is provided with multiple heat-conducting rods 34. The zinc diffusion agent and the power fittings are added between the notch 8 and the middle of the inner shell 7. The main heating rod 33 and the heat-conducting rods 34 are inserted into the zinc diffusion agent, which can uniformly heat the zinc diffusion agent.
[0024] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the uniform feeding assembly 11 includes a feeding plate 35, a connecting shaft 36, and a torsion spring 37. The inner wall of the inner housing 7 at one end of the notch 8 is symmetrically provided with mounting holes 38. The feeding plate 35 has connecting shafts 36 symmetrically provided at both ends. The feeding plate 35 is rotatably mounted within the mounting holes 38 via the connecting shafts 36. The torsion spring 37 is sleeved on the connecting shafts 36, with its two ends respectively located on the side wall of the feeding plate 35 and the bottom wall of the mounting holes 38. Initially, the end of the feeding plate 35 is inclined towards the interior of the inner housing 7. When the power fitting slides down from the feeding plate 35, the feeding plate 35 automatically rotates downwards, thus ensuring that the power fitting does not always fall at the same position on the zinc plating agent inside the inner housing 7.
[0025] like Figure 1 and Figure 2 As shown, the rotary drive assembly 15 includes a gear ring 39, a gear 40, a reducer 41, a linkage shaft 42, and a motor 43. The reducer 41 is located on one side wall of the upper mounting plate 3, and the motor 43 is located on the other side wall of the upper mounting plate 3. The output shaft of the motor 43 passes through the side wall of the upper mounting plate 3 and is connected to the input shaft of the reducer 41. The linkage shaft 42 is connected to the output shaft of the reducer 41. The gear 40 is located at the end of the linkage shaft 42, and the gear ring 39 is located on the outer wall of the end of the outer rotating housing 5. The gear ring 39 meshes with the gear 40.
[0026] like Figure 1 , Figure 8 , Figure 9 and Figure 11As shown, the locking assembly 29 includes a connecting post 45, a stop 46, a compression spring 47, a locking plate 48, and a locking shaft 49. A locking hole 50 is provided at one end of the groove 30 on the outer wall of the end cover 13. A second locking hole 51 is provided at one end of the groove 30 near the filter window 32. The connecting post 45 is located on the upper wall of one end of the sealing baffle 27. The stop 46 is located at the upper end of the connecting post 45. One end of the locking plate 48 is slidably mounted on the connecting post 45. The compression spring 47 is sleeved on the connecting post 45. Both ends of the compression spring 47 are respectively located on the stop 46 and the locking plate 48. One end of the locking shaft 49 is located at the other end of the locking plate 48. When the locking shaft 49 is inserted into the first locking hole 50, the sealing baffle 27 is misaligned with the filter window 32. When the locking shaft 49 is inserted into the second locking hole 51, the sealing baffle 27 blocks the filter window 32.
[0027] like Figure 1 and Figure 2 As shown, the adjustment frame 52 includes a boss 53, a hydraulic rod 54, and a support plate 55. The boss 53 is symmetrically arranged at the edge of the end cover 13, and the support plate 55 is symmetrically arranged on both sides of the upper mounting plate 3. The two ends of the hydraulic rod 54 are respectively arranged on the boss 53 and the support plate 55.
[0028] like Figure 1 and Figure 10 As shown, the end face of the end cap 13 is provided with a rotating groove 56, and universal balls 17 are arranged in an array around the axis in the rotating groove 56. The end face of the outer rotating housing 5 is rotatably disposed in the rotating groove 56.
[0029] In practical use, adjust hydraulic rod 44 to shorten, which causes the upper mounting plate 3 to tilt upward. Then, adjust hydraulic rod 54 to extend, which causes the boss 53 and end cap 13 to separate from the outer rotating shell 5. Then, add the uniformly mixed zinc penetration agent and power fittings into the inner shell 7 until the upper surface of the zinc penetration agent is between the notch 8 and the middle of the inner shell 7. Then, adjust hydraulic rod 44 to extend, so that the upper mounting plate 3 is in a vertical state. Then, adjust hydraulic rod 54 to shorten, which causes the boss 53 and end cap 13 to fit against the outer rotating shell 5. At this time, the sealing baffle 27 blocks the filter window 32. Turn on the main heating rod 33, which heats the heat conducting rod 34 and heats the zinc penetration agent in the inner shell 7 evenly. When motor 43 is turned on, motor 43 drives reducer 41 to rotate, reducer 41 drives linkage shaft 42 to rotate, linkage shaft 42 drives gear 40 to rotate, gear 40 drives gear ring 39 to rotate, gear ring 39 drives outer rotating housing 5 to rotate, outer rotating housing 5 drives grid plate 12 to rotate, and the mixture of zinc penetrating agent and power fitting in inner housing 7 falls from discharge port 9 into the space between two adjacent grid plates 12 and is conveyed upward with grid plate 12. During the upward rotation of grid plate 12, zinc penetrating agent leaks from the gaps in grid plate 12, and power fitting is conveyed upward with grid plate 12 to the gap 8 of inner housing 7, and then slides onto discharge plate 35 and slides down into inner housing 7. When power fitting slides onto discharge plate 35, under the action of gravity, discharge plate 35 will rotate downward, thus ensuring that power fitting does not fall into the same position in inner housing 7. When the outer rotating housing 5 rotates, it drives the rotating tube 4 to rotate, which in turn drives the wheel 23 to rotate. As the wheel 23 gradually contacts the push rod 22 from the concave valley 26 to the convex peak 25, the wheel 23 pushes the push rod 22 to rotate upwards. The push rod 22 drives the telescopic plate 18 to rotate, which in turn drives the connecting rod 19 to rotate. The connecting rod 19 stretches the tension spring 20. When the apex of the convex peak 25 of the wheel 23 contacts the push rod 22, the push rod 22 reaches its maximum height. Then, the tension spring 20 pulls the connecting rod 19 and the telescopic plate 18 back, and the telescopic plate 18 drives the push rod 22 back to its lowest point. During the rotation of the wheel 23, the push rod 22 is intermittently pushed up and pulled back, the telescopic plate 18 swings back and forth, the telescopic plate 18 drives the rotating shaft 6 to swing, the rotating shaft 6 drives the inner shell 7 to swing, thereby generating vibration on the zinc diffusion agent and power fittings inside the inner shell 7. Under the action of vibration and gravity, the power fittings sink to the bottom of the inner shell 7 at the discharge port 9, and then fall back into the grid plates 12 along with the zinc diffusion agent. The above operation is repeated, and the power fittings circulate in the zinc diffusion agent, thereby ensuring that the power fittings have a uniform temperature and full contact with the zinc diffusion agent during the powder zinc diffusion process. After zinc diffusion is completed, allow the device to cool naturally to room temperature. Then, adjust hydraulic rod 44 to tilt the upper mounting plate 3 downwards. Place the recovery container under the end cap 13 and the outer rotating housing 5. Slide the sealing baffle 27 upwards. Then, insert the locking shaft 49 into the locking hole 50 to open the filter window 32. Turn on the motor 43 again. The outer rotating housing 5 drives the grid plate 12 to rotate. The zinc diffusion agent between the grid plates 12 slides from the baffles 28 in the filter window 32 into the recovery container. The power fittings circulate in the device along with the grid plates 12. After the zinc diffusion agent is recovered, adjust hydraulic rod 54 to extend. Hydraulic rod 54 pushes the boss 53 and the end cap 13 to separate from the outer rotating housing 5. The power fittings slide from between the outer rotating housing 5 and the end cap 13.
