Description

Technical Field

[0001] This utility model relates to the field of bolt surface treatment technology, and specifically to a bolt surface treatment device. Background Technology

[0002] After bolts are manufactured, they need to undergo various surface treatments to achieve corrosion resistance, wear resistance, and improved appearance. Existing surface treatment methods for bolts mainly include oxidation, electroplating, passivation, hot-dip galvanizing, and phosphating, etc.

[0003] Chinese utility model patent with authorization announcement number CN217173880U discloses a rapid pickling device for surface treatment of hot-dip galvanized bolts. The device uses a pickling mechanism connected to the bottom of an overhead crane to clamp and pickle a cylinder containing bolts. During pickling, a reciprocating rotating rod can rotate the bolts inside the cylinder, improving the quality of bolt pickling. After pickling, a clean water spray pipe can spray clean water onto the bolts inside the cylinder to remove residual residue from the bolt coating surface, making it convenient to use.

[0004] Although the aforementioned patent can pickle bolts, it still has the following shortcomings: First, the device can only be applied to a single surface treatment of bolts. When other surface treatments are required, other treatment devices or surface treatment agents need to be replaced, which increases the number of operation steps and reduces the efficiency of bolt surface treatment. Second, in the aforementioned patent, the cylinder rotates in the vertical direction. During the rotation of the cylinder, the bolt moves synchronously with the cylinder, resulting in poor rotation effect of the bolt inside the cylinder, which leads to unsatisfactory bolt surface treatment effect and efficiency.

The immersion part is hollow inside to hold bolts, and the immersion part is provided with several liquid inlet channels communicating with its interior.

[0028] Different surface treatment agents are poured into several processing units, and the small overhead crane 4 is moved to one end of the surface treatment tank 1, so that the immersion part is directly above the processing unit at one end of the surface treatment tank 1. Then, bolts are inserted into the immersion part, and then the small overhead crane 4 is started to lower the immersion part into the processing unit and immerse it in the surface treatment agent. At the same time, the drive unit is started to drive the immersion part to rotate through the transmission unit, thereby performing surface treatment. After the treatment is completed, the small overhead crane 4 is started to lift the immersion part and move it directly above the next processing unit, and then the above operation is repeated. The operation is simple and convenient, and multiple surface treatments can be performed on bolts in sequence quickly, which improves the processing efficiency. At the same time, during the rotation of the immersion part, the bolts can be continuously raised and lowered, so that the bolts can fully contact the surface treatment agent, ensuring the efficiency and quality of surface treatment.

The plurality of liquid inlet channels are a plurality of liquid passage holes 71 evenly opened on the side wall of the hexagonal cage 7 and the closing door 72. An outer edge 74 is fixedly mounted on the inner wall opposite to the opening and the closing door 72. The outer edge 74 extends along its length. The locking mechanism includes several threaded holes 75. The locking element consists of several wing bolts 73 located on the side of the closed door 72 away from the hexagonal cage 7. The threads of the wing bolts 73 pass through the closed door 72 and are threadedly connected to the corresponding threaded holes 75. When a bolt needs to be inserted, the wing bolts 73 are loosened to disengage them from the corresponding threaded holes 75. Then, the closed door 72 is rotated open, and the bolt is poured into the hexagonal cage 7. The closed door 72 is then rotated closed, and the wing bolts 73 are sequentially tightened to re-thread them into the corresponding threaded holes 75, thereby fixing the closed door 72 and ensuring that the bolt does not fall out of the hexagonal cage 7.

[0030] The support unit includes a U-shaped frame 5 fixedly connected to two slings 41. The drive unit is fixedly installed on the upper part of the horizontal section of the U-shaped frame 5.

[0033] The starter motor 6 drives the first sprocket 62 to rotate, which in turn drives the second sprocket 63 to rotate via the chain 64, thereby driving the hexagonal cage 7 to rotate via the shaft 8.

[0034] like Figure 1As shown, according to another embodiment of the present invention, the bolt surface treatment device preferably has two opposing slide rail assemblies arranged along its length on the upper part of the surface treatment groove 1. Each slide rail assembly includes several first support columns 12, second support columns 2, and a track 3.

The counterweight 52 and the motor 6 are located between the two lifting cables 41 and are arranged close to the two lifting cables 41 in a one-to-one correspondence. The weight of the counterweight 52 is selected according to the actual use, and the purpose is to balance the force on the two lifting cables 41 through the counterweight 52, thereby ensuring the service life of the two lifting cables 41.

[0037] The working principle of this utility model is as follows: When using this utility model, firstly, different surface treatment agents are poured into several processing units.

Then, several wing bolts 73 are loosened to disengage them from the corresponding threaded holes 75, thereby rotating and opening the sealing door 72. Bolts are then poured into the hexagonal cage 7. The sealing door 72 is then rotated and closed, and several wing bolts 73 are sequentially tightened to re-thread and reconnect with the corresponding threaded holes 75, thereby fixing the sealing door 72. Finally, the small overhead crane 4 is started to move the hexagonal cage 7... The bolts are lowered into the processing unit and immersed in the surface treatment agent. At the same time, the motor 6 is started to drive the first sprocket 62 to rotate, which drives the second sprocket 63 to rotate through the chain 64. The second sprocket 63 drives the hexagonal cage 7 to rotate through the rotating shaft 8, thereby fully surface treating the bolts inside the hexagonal cage 7. After the treatment is completed, the small crane 4 is started to lift the hexagonal cage 7 and move it to the next processing unit. Then the above operation is repeated. After the bolts have been surface treated in all processing units, the small crane 4 is moved to one end of the two tracks 3 and the two second support columns 2. Then, several wing bolts 73 are loosened to disengage them from the corresponding threaded holes 75, thereby rotating and opening the closed door 72 to pour out the bolts.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
