Description

Technical Field

[0001] This utility model relates to the technical field of bearing steel ball production and processing equipment, specifically to a degreasing device for bearing steel balls after heat treatment. Background Technology

[0002] Bearing steel balls are the core rolling elements of a bearing, bearing the main load during bearing operation. Their quality directly affects the bearing's precision, lifespan, and reliability. Among these processes, heat treatment of bearing steel balls is the core step that determines their mechanical properties. The purpose is to obtain a uniform martensitic structure for the steel balls through controlled heating, holding, and cooling processes, while simultaneously eliminating internal stresses and laying the foundation for subsequent precision machining.

[0003] After heat treatment, bearing steel balls typically retain a large amount of oil and may also contain oxide scale debris. These require efficient degreasing equipment to remove, preventing them from affecting subsequent grinding and assembly processes. Current methods for degreasing bearing steel balls involve pouring large batches of balls into a degreasing solution and cleaning them through immersion, vibration, and agitation.

[0004] However, due to the high density of steel balls, the stirring process becomes difficult when a large number of steel balls accumulate. Furthermore, using the same vibration method on steel balls of different sizes makes it difficult for them to rotate smoothly due to the inertia of the steel balls. If the vibration is too strong, it can also cause the steel balls to collide and be damaged. Utility Model Content

[0005] To address the aforementioned issues, a degreasing device for bearing steel balls after heat treatment is provided. This device uses a rotating shaft to drive the steel balls to a degreasing sponge for friction degreasing. The degreasing process is gentle and causes minimal damage to the steel balls. During feeding, one ball per groove is achieved, facilitating continuous feeding of steel balls and saving time and effort. The rotating disc is equipped with an adjusting block to adjust the depth of the receiving groove, allowing the disc to accommodate steel balls of different sizes and also facilitating adjustment of the distance between the outer wall of the steel ball and the degreasing sponge.

[0006] To address the problems in the existing technology, this utility model provides a degreasing device for bearing steel balls after heat treatment, comprising: The machine body is equipped with a liquid storage tank and a pump. A spray pipe is installed at the upper part of the machine body. The machine body has a cleaning chamber with an open side. A drain valve pipe is installed on the inner wall at the bottom of the cleaning chamber. A receiving platform is provided on one side of the machine body. A rotating disk is provided in the cleaning chamber and several are evenly distributed along the axis of the cleaning chamber. A rotating shaft is provided in the middle of the rotating disk. The rotating shaft extends laterally along the axis of the cleaning chamber to pass through the cleaning chamber and is rotatably connected to the machine body. The rotating disk has receiving grooves arranged in a ring array with the rotating shaft as the center. The rotating disk is installed on the rotating shaft by fastening bolts. An oil-removing sponge is arranged in an arc shape at the bottom of the rotating disk. A mounting frame is provided on the outside of the oil-removing sponge, and the oil-removing sponge is sleeved in the mounting frame. The pump is equipped with an inlet and an outlet, which are connected to a storage tank and a spray pipe respectively via pipes.

[0008] Preferably, the cleaning chamber is provided with a protrusion, and the open part of the cleaning chamber is provided with an outlet frame matching the number of rotating disks.

[0009] Preferably, one end of the mounting bracket contacts the bottom of the protrusion and the other end of the mounting bracket contacts the back of the export frame, which is located diagonally below the rotating disk.

[0010] Preferably, the top of the rotating disk is provided with a discharge frame for distributing materials into the receiving groove, and the bottom of the discharge frame is provided with a guide pipe located directly above the rotating disk.

[0011] Preferably, the rotating disk has an installation cavity, the side of the installation cavity is open and the four sides of the installation cavity are connected to the receiving groove, the receiving groove is provided with an adjustment block, and the rotating disk is provided with a cover plate at the opening of the installation cavity.

[0012] Preferably, a rotating ring is provided inside the mounting cavity, which is sleeved on the outside of the rotating shaft. The rotating ring is provided with connecting arms in the same number as the receiving grooves. The ends of the connecting arms are provided with hinge blocks. The two ends of the connecting arms are rotatably connected to the rotating ring and the adjusting block respectively through the hinge blocks.

[0014] Preferably, the positioning plate is provided with several positioning grooves for adjusting the position of the rotating ring by means of a connecting screw and a sliding block.

[0015] The advantages of this utility model compared to the prior art are: 1. The bearing steel balls after heat treatment are degreased using a single groove and single steel ball method, which effectively avoids the steel balls from colliding and being damaged during the degreasing process. The degreasing agent is sprayed onto the surface of the steel balls by spraying, and at the same time, a rotating shaft drives the steel balls to rotate to the degreasing sponge for friction degreasing. The degreasing process is gentle and causes little damage to the steel balls.

Detailed Implementation

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-5 As shown, a degreasing device for bearing steel balls after heat treatment includes: The machine body 1 is equipped with a liquid storage tank 1a and a pump 1b. A spray pipe 1c is installed diagonally above the machine body 1. The machine body 1 has a cleaning chamber with an open side. A drain valve pipe is installed on the inner wall at the bottom of the cleaning chamber. A receiving platform is provided on one side of the machine body 1.

[0030] The pump 1b is provided with an inlet and an outlet, which are connected to the storage tank 1a and the spray pipe 1c respectively via pipes. It should be noted that after the steel balls are placed inside the machine body 1, the degreasing agent in the storage tank 1a is transported through the inlet pipe to the spray pipe 1c via the pump 1b, and sprayed onto the surface of the steel balls, allowing the degreasing agent to react with the oil on the steel ball surface. When there is too much liquid in the cleaning chamber, the excess liquid can be drained by opening the drain valve. The receiving platform is used to hold the collection frame containing the degreased steel balls.

[0031] See Figures 1-3 , Figure 5 and Figure 6 As shown, a rotating disk 2 is arranged in the cleaning chamber and several are evenly distributed along the axis of the cleaning chamber. A rotating shaft 2a is provided in the middle of the rotating disk 2. The rotating shaft 2a extends laterally along the axis of the cleaning chamber to penetrate the cleaning chamber and is rotatably connected to the machine body 1. The rotating disk 2 has receiving grooves arranged in a ring array with the rotating shaft 2a as the center, and the rotating disk 2 is installed on the rotating shaft 2a by fastening bolts. The oil-removing sponge 3 is arranged in an arc shape at the bottom of the rotating disk 2. A mounting bracket 3a is provided on the outside of the oil-removing sponge 3, and the oil-removing sponge 3 is sleeved in the mounting bracket 3a.

[0032] It should be noted that after the steel ball is placed in the receiving groove, the rotating shaft 2a drives the rotating disk 2 to rotate, which in turn moves the steel ball in the receiving groove to the degreasing sponge 3. The friction between the degreasing sponge 3 and the steel ball causes the steel ball to rotate, thereby achieving all-round wiping of the steel ball by the degreasing sponge 3. The degreasing process is gentle and causes little damage to the steel ball.

[0033] See Figure 3 As shown, the end of the rotating shaft 2a is provided with a drive mechanism for driving the rotating disk 2 to rotate.

[0034] It should be noted that the drive mechanism includes a drive motor for driving, a reduction gear used in conjunction with the drive motor, and a coupling connecting the rotating shaft 2a and the reduction gear. In use, the output end of the drive motor drives the reduction gear, which in turn drives the rotating shaft 2a to rotate via the coupling, thereby causing the rotating disk 2 on the outside of the rotating shaft 2a to rotate.

[0035] See Figures 1-3 As shown, the cleaning chamber is provided with a protrusion, and the open part of the cleaning chamber is provided with an outlet frame 1d that matches the number of rotating disks 2.

[0036] One end of the mounting bracket 3a contacts the bottom of the protrusion and the other end of the mounting bracket 3a contacts the back of the export frame 1d, which is located diagonally below the rotating disk 2.

[0037] It should be noted that when the drive mechanism drives the steel ball at the outer rotating disk 2 of the rotating shaft 2a to the outlet frame 1d, the inner wall of the receiving groove at the steel ball is set at an angle, and the steel ball inside can slide along the inner wall of the receiving groove to the outlet frame 1d and then slide out for collection.

[0038] See Figure 2 and Figure 3 As shown, the top of the rotating disk 2 is provided with a discharge frame 4 for distributing materials into the receiving groove, and the bottom of the discharge frame 4 is provided with a guide pipe 4a located directly above the rotating disk 2.

[0039] It should be noted that, in order to facilitate the material distribution in the receiving groove of the rotating disc 2, the steel ball is placed in the discharge frame 4. At this time, the steel ball can enter the guide pipe 4a along the discharge frame 4, and under the guidance of the guide pipe 4a, the steel ball is smoothly sent into the receiving groove, achieving the material distribution effect of one ball per groove.

[0040] See Figure 2 and Figures 7-9 As shown, the rotating disk 2 has an installation cavity inside, the side of the installation cavity is open and the four sides of the installation cavity are connected to the receiving groove, the receiving groove is provided with an adjustment block 2b, and the rotating disk 2 is provided with a cover plate 2c at the opening of the installation cavity.

[0041] A rotating ring 2d is provided inside the mounting cavity. The rotating ring 2d is sleeved on the outside of the rotating shaft 2a. The rotating ring 2d is provided with connecting arms 2d1 in the same number as the receiving grooves. The ends of the connecting arms 2d1 are provided with hinge blocks. The two ends of the connecting arms 2d1 are rotatably connected to the rotating ring 2d and the adjusting block 2b respectively through the hinge blocks.

[0042] It should be noted that rotating the rotating ring 2d causes the connecting arm 2d1 to fold via the hinge block. As the connecting arm 2d1 folds, it pulls the adjusting block 2b via the hinge block, thereby adjusting the depth of the receiving groove. This allows the receiving groove to stably receive steel balls of different sizes, and also facilitates the adjustment of the distance between the outer wall of the steel ball and the degreasing sponge.

[0043] See Figure 7 and Figure 8 As shown, the cover plate 2c has an adjustment groove and a positioning plate 2c1 is connected to the back of the cover plate 2c. A sliding block 2c2 is provided in the adjustment groove, and the end of the sliding block 2c1 is connected to the rotating ring 2d.

[0044] The positioning plate 2c1 is provided with several positioning grooves for adjusting the position of the rotating ring 2d by connecting screws and sliding blocks 2c1.

[0045] It should be noted that before rotating the rotating ring 2d, first remove the connecting screw that positions the positioning plate 2c1 and the sliding block 2c1. At this point, the sliding block 2c1 can be pushed to move along the adjusting groove, thereby driving the rotating ring 2d to rotate. After rotating the rotating ring 2d to the appropriate position, the positioning plate 2c1 and the sliding block 2c1 can be locked again using the connecting screw.

[0046] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
