[0034] As Figure 1 and Figure 2 shown, an end anodizing device 100 for a part is provided in an embodiment of the present utility model, including an electrolyte container 110 and a conveying structure 120 for conveying the part;

[0035] The electrolyte container 110 has opposite starting side walls 111, ending side walls 113, and a working side wall 112 connecting the starting side wall 111 and the ending side wall 113. A working port 114 for the end of the part to pass through is provided on the electrolyte container 110, and the working port 114 extends from the starting side wall 111 along the working side wall 112 and penetrates the ending side wall 113 all the way.

[0036] A water pump 130 is provided in the electrolyte container 110, and the water pump 130 is used to pump the electrolyte in the anodizing tank 200 to a liquid level higher than the working port 114.

[0037] The conveying structure 120 is located on one side of the electrolyte container 110 close to the working side wall 112, and the conveying structure 120 is parallel to the working port 114.

[0038] The usage method of the end part anodizing device 100 for parts provided by the embodiments of the present utility model is as follows:

[0039] Place the parts (especially long strip-shaped parts) in the conveying structure 120. During the conveying process of the conveying structure 120, the end parts of the parts enter the working port 114 from the starting side wall 111 and move along the length direction of the working port 114 until they move out of the working port 114 from the ending side wall 113.

[0040] Under the action of the water pump 130, the electrolyte in the anodizing tank 200 is pumped to a liquid level higher than the working port 114. During the movement of the end parts of the parts in the working port 114, the end parts of the parts are completely immersed in the electrolyte, and the parts are electrically connected to the positive electrode to undergo anodic oxidation in the electrolyte.

[0041] The faster the conveying speed of the conveyor belt, the shorter the time for the end parts of the parts to be immersed in the electrolyte and the shorter the anodic oxidation time, and vice versa. By controlling the conveying speed of the conveying structure 120 for the parts, the anodic oxidation time is controlled to ensure that the parts are uniformly and fully oxidized in the electrolyte.

[0042] Optionally, the end part anodizing device 100 for parts further includes a motor (not shown in the figure). The motor is connected to the conveying structure 120 and is used to drive the conveying structure 120 to move. By setting the motor speed, the anodic oxidation time can be indirectly controlled to realize the automated operation of the anodic oxidation of the end parts of the parts.

[0043] Optionally, the number of electrolyte containers 110 is 2. The working side walls 112 of the 2 electrolyte containers 110 are arranged oppositely, and the conveying structure 120 is located between the two working side walls 112. The 2 electrolyte containers 110 are used to contain the electrolyte for anodizing the opposite ends of the parts.

[0044] When the number of electrolyte containers 110 is 2, there are two electrical connection methods during the working process:

[0045] The first one: The material of the conveying structure 120 is a conductive material. The conveying structure 120 is electrically connected to the positive electrode, and the wall of the electrolyte container 110 is electrically connected to the negative electrode. At this time, if electrolytes are placed in both of the two electrolyte containers, the device can simultaneously anodize the opposite ends of the parts, which is suitable for processing parts that need to be anodized at both ends; if only one of the two electrolyte containers contains electrolyte, the device is used to anodize one end of the part.

[0046] The second one: The material of the conveying structure 120 is an insulating material. One of the walls of the two electrolyte containers 110 is electrically connected to the positive electrode, and the other is electrically connected to the negative electrode. At this time, the device can anodize the end parts of the parts in the electrolyte container 110 that is electrically connected to the negative electrode.

[0047] Of course, it should be noted that in other embodiments of the present utility model, the number of electrolyte containers 110 can also be 1. When the number of electrolyte containers 110 is one, the device can only perform anodic oxidation on one end of the part during one operation.

[0048] Optionally, a brush structure 140 covering the working port 114 is provided on the electrolyte container 110, and the brush structure 140 is used to slow down the discharge of the electrolyte from the inside of the electrolyte container 110 through the working port 114.

[0049] During the working process, the electrolyte is pumped from below to the high liquid level under the action of the water pump 130. Due to the setting of the working port 114, the electrolyte will discharge from the working port 114 out of the electrolyte container 110. If the electrolyte discharges too fast, it is difficult to make the height of the electrolyte higher than the working port 114. Therefore, setting the brush structure 140 can ensure that the end of the part can enter the working port 114 while effectively slowing down the discharge speed of the electrolyte through the working port 114.

[0050] Specifically, the brush structure 140 includes at least a pair of brush body groups. Each pair of brush body groups includes 2 brush bodies 141. Each brush body 141 includes a fixing member 142 and densely arranged bristles 143 fixed on the fixing member 142;

[0051] The 2 brush bodies 141 in each pair of brush body groups are arranged oppositely in an up-and-down manner. The fixing members 142 of the 2 brush bodies 141 are respectively connected to the upper and lower edge parts of the working side wall 112 corresponding to the working port 114, and the bristles 143 of the upper and lower 2 brush bodies 141 cover the working port 114.

[0052] During work, the end of the part passes through between the bristles 143 of the upper and lower 2 brush bodies 141.

[0053] Optionally, the conveying structure 120 is a conveyor belt, and a plurality of part limiting structures are arranged along the length direction on the upward-facing surface of the conveyor belt.

[0054] Setting the part limiting structure can limit the parts on the conveyor belt to ensure that the parts can be stably conveyed, thereby ensuring stable anodic oxidation. In addition, due to the setting of the brush structure 140, there is a certain resistance when the part passes through the working port 114. Setting the part limiting structure can enable the part to still pass through the working port 114 in the presence of the resistance of the bristles 143.

[0055] Optionally, the part limiting structure is a limiting groove 121.

[0056] A vibration feeding device can be set at the upstream of the conveyor belt. A basket for holding parts is arranged in cooperation with the vibration feeding device. The basket is inclined. Through the vibration of the vibration feeding device, the parts in the basket enter into the limiting groove 121, and the feeding of the conveyor belt is completed.

[0057] A vibration feeding device can be set at the downstream of the conveyor belt. Through the vibration of the vibration discharging device, the parts processed on the conveyor belt enter the next production link.

[0058] Optionally, the size of the limiting groove 121 corresponds to the size of one part, that is, exactly one part can be clamped in one limiting groove 121. When the part to be processed is the throttle valve shaft body 300, the size of the limiting groove 121 corresponds to the size of the throttle valve shaft body 300.

[0059] Optionally, the length direction of the limiting groove 121 is perpendicular to the length direction of the conveyor belt. In this way, when the conveyor belt conveys the throttle valve shaft body 300, the throttle valve shaft body 300 is vertically located above the conveyor belt.

[0060] As Figure 3 shown, further, each limiting groove 121 is composed of two inclined planes arranged on the conveyor belt. That is, in the cross-section perpendicular to the conveying surface and parallel to the length direction of the conveyor belt, the shape of the limiting groove 121 is V-shaped.

[0061] When the cross-sectional shape of the limiting groove 121 is V-shaped, it is more convenient for the parts to vibrate in and out.

[0062] Optionally, the conveyor belt is a flexible conveyor belt.

[0063] Optionally, the size of the working port 114 corresponds to the diameter of the throttle valve shaft body 300.

[0064] When the size of the working port 114 corresponds to the diameter of the throttle valve shaft body 300, the device is used for anodizing the end of the throttle valve shaft body 300.

[0065] As Figure 2 shown, an embodiment of the present invention further provides an end anodizing system for parts, including an anodizing tank 200 and an end anodizing device 100 for parts arranged in the anodizing tank 200.

[0066] During operation, the anodizing tank 200 is filled with electrolyte. The bottom end of the electrolyte container 110 is communicated with the anodizing tank 200. The water pump 130 continuously pumps the liquid in the anodizing tank 200 into the high liquid level of the electrolyte container 110, and then the electrolyte is discharged into the anodizing tank 200 through the working port 114, and so on in a cycle.

[0067] In summary, the end anodizing device 100 for parts provided by the embodiments of the present utility model can achieve end anodizing of parts, and has the following characteristics:

[0068] a) The oxidation area is accurately controlled to be the end, avoiding unnecessary overall oxidation. After anodizing the parts, the corrosion resistance and wear resistance of the product are improved;

[0069] b) The degree of automation is high, reducing manual operation, lowering production costs, and improving production efficiency;

[0070] c) The equipment is reasonably designed, easy to operate, easy to maintain and clean, meeting the requirements of modern production.

[0071] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
