Description

Technical Field

[0001] This utility model relates to a blackening treatment device for worm gear shafts. Background Technology

[0002] Currently, the blackening process typically involves immersing the metal in a solution of sodium hydroxide and sodium nitrite. To ensure uniform mixing, a stirring structure is often installed at the bottom of the immersion tank. However, most tanks do not have a limit frame, which can easily damage the stirring structure when the immersion tank moves downwards. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the existing technology and to provide a worm gear shaft blackening treatment device with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the worm gear shaft blackening treatment equipment includes an immersion tank and an immersion frame. Its structural features are as follows: it also includes a limiting frame, a guide seat, a guide groove, and a guide strip. The limiting frame is fixedly installed in the immersion tank and located at the bottom of the immersion tank. A guide seat is provided at each of the four corners of the immersion tank. A guide groove is provided on the guide seat. A guide strip is provided at each of the four corners of the immersion frame. The guide strip is located in the guide groove.

[0005] Furthermore, the limiting frame is arranged in a U-shape, the middle part of the limiting frame is a stirring area, and a stirring structure is provided in the stirring area.

[0006] Furthermore, the stirring structure includes a motor and stirring blades, the stirring blades being located within the stirring area and driven by the motor, which is positioned at the bottom of the soaking tank.

[0007] Furthermore, the soaking frame is connected to the piston rod of the cylinder, and the cylinder barrel is mounted on the soaking tank.

[0008] Furthermore, the bottom of the soaking tank is provided with support legs.

[0009] Compared with the prior art, the present invention has the following advantages: the worm gear shaft blackening treatment equipment can limit the soaking frame during the lifting and lowering process by setting a limit frame in the soaking tank, so as to prevent the soaking frame from damaging the stirring blade and affecting its service life.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0014] Example

[0015] See Figures 1 to 2 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0016] The worm gear shaft blackening treatment device in this embodiment includes an immersion tank 1, an immersion frame 2, a limiting frame 3, a guide seat 4, a guide groove 5, and a guide bar 6. The limiting frame 3 is fixedly installed in the immersion tank 1 and is located at the bottom of the immersion tank 1. A guide seat 4 is provided at each of the four corners of the immersion tank 1, and a guide groove 5 is provided on the guide seat 4. A guide bar 6 is provided at each of the four corners of the immersion frame 2, and the guide bar 6 is located in the guide groove 5.

[0017] In this embodiment, the limiting frame 3 is arranged in a U-shape. The middle part of the limiting frame 3 is the stirring area. A stirring structure is provided in the stirring area. The stirring structure includes a motor 7 and a stirring blade 8. The stirring blade 8 is located in the stirring area and is driven by the motor 7. The motor 7 is located at the bottom of the soaking tank 1.

[0018] In this embodiment, the soaking frame 2 is connected to the piston rod of the cylinder 9, the cylinder barrel of the cylinder 9 is set on the soaking tank 1, and the bottom of the soaking tank 1 is provided with support legs 10.

[0019] Specifically, during use, the worm gear shaft blackening treatment equipment uses cylinder 9 to control the immersion frame 2 to rise, placing the worm gear shaft inside the immersion frame 2. Then, cylinder 9 controls the immersion frame 2 to fall, immersing the worm gear shaft inside the immersion frame 2 into the liquid in the immersion tank 1. The liquid in the immersion tank 1 can be stirred by stirring blade 8, which is located in the stirring area. The limiting frame 3 can limit the immersion frame 2 to prevent it from contacting the stirring blade 8 during its descent.

[0020] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined by the claims, all of which should fall within the protection scope of this utility model.
