Description

Technical Field

[0001] The utility model relates to the technical field of bolt surface treatment, and more specifically, to a surface treatment device for bolts. Background Art

[0002] Bolts are a common mechanical part. They are cylindrical threaded fasteners that are matched with nuts. During the processing and production of bolts, in order to complete tasks such as rust prevention, the surface of the bolts needs to be treated, such as immersing the bolts in a corresponding treatment liquid.

[0003] The authorized utility model patent with announcement number CN212335297U discloses a device called "A special rotating barrel device for bolt surface treatment". By setting up a barrel 2, a first gear disc 8 and a drive motor 13, the barrel 2 can rotate around its axis, thereby causing the bolts to roll in the barrel 2, so that the bolts in the barrel 2 are fully in contact with the treatment agent in the reaction tank, thereby improving the uniformity of the bolt surface treatment.

[0004] The above patent has the following problems in actual application: during the loading and unloading of the bolts, multiple locking parts are required to fix and disassemble the cylinder 2 and the sealing cover 4, which is time-consuming and labor-intensive. During the rotation of the cylinder 2, the frequent collisions between the internal bolts and the sealing cover 4 can easily cause the sealing cover 4 to loosen or even be damaged; secondly, the rotation of the first gear disc 8 drives the cylinder 2 to rotate around its axis, thereby causing a certain amount of bolts to roll in the cylinder 2. The bolts located on the inner side of the cylinder 2, especially at the center, cannot always fully contact the treatment liquid. Utility Model Content

[0025] Example 1:

[0026] See also Figure 1-3, a surface treatment device for bolts, including a reaction tank 1, the reaction tank 1 contains a treatment liquid, a motor base 2 is fixedly connected to the left wall of the reaction tank 1, a motor 3 is installed on the motor base 2, the left and right ends of the reaction tank 1 are fixedly connected to mounting bases 4, a pair of mounting bases 4 are provided with rotating holes, a driven shaft 5 is rotatably connected in the rotating holes, the output end of the motor 3 is fixedly connected to a driving shaft, a transmission belt 6 is provided between the driving shaft and the driven shaft 5, a reaction bucket 7 is provided at the inner end of the reaction tank 1, a plurality of equally spaced seepage holes 701 are provided on the surface of the inner reaction bucket 7, the driven shaft 5 passes through the reaction bucket 7, and a receiving plate 8 and a positioning plate 9 are fixedly connected between the front and rear ends of the reaction bucket 7 and the reaction tank 1, respectively. The outer end of the driving shaft 5 is fixedly connected to a three-row feed rod group 10. The feed rods on the three-row feed rod group 10 are arranged at equal intervals, and the feed rods on the two adjacent rows of feed rod groups 10 are staggered. The length of the feed rod matches the inner diameter specification of the reaction bucket 7. When the bolts are subjected to Dacromet infiltration treatment, the motor 3 drives the driven shaft 5 and the three-row feed rod group 10 at the outer end of the driven shaft 5 to perform high-frequency and small-amplitude forward and reverse rotations, thereby shifting the bolts accumulated at the bottom. The bolts are placed at no more than 50% of the volume of the reaction bucket 7 to ensure the feeding effect of the feed rod group 10, so that the treatment liquid penetrates from the gaps between the bolts and fully contacts the bolt surface, thereby improving the reaction efficiency and treatment effect.

[0027] See also Figure 1-3 The outer end of the driven shaft 5 is also fixedly connected to a pair of transverse plates 11, and a screen 12 is fixedly connected between the pair of transverse plates 11. The screen holes on the discharge portion 702 and the screen 12 are smaller than the size specifications of the bolts. The spacing between the ends of the pair of transverse plates 11 away from each other matches the length specifications of the reaction bucket 7. The width of the screen 12 matches the inner diameter specifications of the reaction bucket 7. The cross section of the reaction bucket 7 is an arc shape, and the driven shaft 5 is arranged at the center of the reaction bucket 7. A discharge portion 702 is provided on the side of the reaction bucket 7 close to the receiving plate 8, and the discharge portion 702 is low. At the horizontal height of the driven shaft 5, a transmission component 13 is provided on the front side of the reaction tank 1, and the upper surface of the receiving plate 8 is set as a smooth inclined surface. After the bolts are treated with Dacromet infiltration, the motor 3 is started to drive the driven shaft 5 and the transverse plate 11 and the screen 12 to deflect to one side of the discharge part 702. The treated bolts can be moved to the receiving plate 8 without bringing out excess treatment liquid from the reaction bucket 7. The bolts slide onto the transmission component 13 through the receiving plate 8 with a smooth upper surface and an inclined surface, and are then operated by the transmission component 13 for subsequent curing and cooling treatment.

[0028] When using this equipment, personnel first start the motor 3 to drive the driven shaft 5 to rotate, and rotate the material rod group 10, the horizontal plate 11 and the screen 12 to the position outside the reaction bucket 7, then put the bolts into the reaction bucket 7, and then use the motor 3 to drive the three-row material rod group 10 to rotate into the reaction bucket 7 and perform high-frequency and small-amplitude forward and reverse rotation, so that the bolts accumulated in a group are moved at high frequency and in a small amplitude, allowing the processing liquid to penetrate from the gaps between the bolts and fully contact the bolt surface. When unloading, the motor 3 drives the horizontal plate 11 and the screen 12 to the side. One end of the discharge portion 702 is deflected, and when the bolt is operated onto the receiving plate 8, it can be ensured that excess processing liquid will not be brought out from the reaction bucket 7. Finally, the bolt is transported to the transmission component 13 through the receiving plate 8 for subsequent processing. Compared with the existing technology, the utility model greatly simplifies the loading and unloading process by abandoning the traditional fixing method between the cylinder and the sealing cover, which can effectively improve the operating efficiency. At the same time, the high-frequency and small-amplitude forward and reverse rotation of the material rod group 10 makes the processing liquid fully contact with the bolt, which can improve the uniformity of the bolt processing and ensure the stability and consistency of the processing quality.

[0029] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
