Description

Technical Field

[0001] This utility model belongs to the field of bearing cleaning technology, specifically a dust cleaning device for tapered roller bearings. Background Technology

[0002] Tapered roller bearings are a common type of rolling bearing. Their design combines radial and axial load carrying capacity and they are widely used in industrial machinery, automobiles, heavy equipment, and other fields. Before installation, bearings are prone to accumulating dust on their surface after being left for a long time, which affects the bearing's performance. It is necessary to clean the surface dust before installation. When using existing bearing dust cleaning devices, if the operator places the bearing on the workbench, the lack of bearing position adjustment can cause the larger bearing edge to extend beyond the edge of the rotating disk. This makes it impossible for the cleaning brush to cover the bearing and can easily damage the device. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a dust cleaning device for tapered roller bearings, which solves the problem that when the operator places the bearing on the workbench in the existing dust cleaning device for bearings, the lack of adjustment of the bearing position causes the larger bearing edge to easily exceed the edge of the rotating disk, thus making it impossible for the cleaning brush to cover the bearing and easily damaging the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust cleaning device for tapered roller bearings, comprising a worktable, a rotating disk rotatably connected to the top of the worktable via a bearing, four equidistant limiting grooves on the top of the rotating disk, several locking interfaces symmetrically arranged on both sides of the limiting grooves, a sliding block slidably connected inside the limiting grooves, protrusions symmetrically fixedly installed on both sides of the sliding block, and the protrusions corresponding to the locking interfaces, an adjusting bolt threadedly connected to the top of the sliding block, a positioning block provided on the surface of the adjusting bolt at the top of the sliding block, a bearing body fitted onto the surface of each positioning block, an electric telescopic rod fixedly installed on one side of the top of the worktable, a top seat fixedly installed on the top of the electric telescopic rod, a motor fixedly installed on the bottom side of the top seat away from the electric telescopic rod, a cleaning brush fixedly installed at the output end of the motor, and the cleaning brush corresponding to the bearing body.

[0005] As a further embodiment of this utility model: the bottom of the top seat is fixedly installed with an isolation cover on the surface of the motor, and the output end of the motor extends through to the bottom of the isolation cover, and the isolation cover covers the surface of the cleaning brush.

[0006] As a further embodiment of this utility model: dust collection heads are fixedly installed on both sides of the inner wall of the isolation cover, a fan is fixedly installed on the top of the top seat, and the input end of the fan and the dust collection head are connected through a conduit, and a dust collection chamber is fixedly connected to the output end of the fan.

[0007] As a further embodiment of this utility model: a snap-fit ​​block is fixedly connected to the bottom of the rotating disk, and the snap-fit ​​block is provided with snap-fit ​​grooves at equal angles.

[0008] As a further embodiment of this utility model: a second motor is fixedly installed at the bottom of the workbench, and a rotating seat is fixedly connected to the output end of the second motor, with a snap-fit ​​block overlapping the top edge of the rotating seat.

[0009] As a further embodiment of this utility model: a rolling block is rotatably connected to one side of the rotating seat via a pin, and the rolling block engages with the locking groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This dust cleaning device for tapered roller bearings uses an adjusting bolt and a sliding block. A suitable locating block of appropriate size is selected based on the bearing body size and placed on top of the sliding block. The adjusting bolt is then threaded through the locating block and connected to the sliding block. The sliding block moves to a suitable position inside the limiting groove. Tightening the adjusting bolt causes the sliding block to move upwards within the limiting groove, causing the protrusion on the sliding block to engage in the locking interface. This prevents the locating block from easily moving on the rotating disk, enabling positioning of bearing bodies of various sizes and ensuring that the edge of the bearing body does not extend beyond the edge of the rotating disk.

[0011] 2. The dust cleaning device for tapered roller bearings uses a rotating seat and a snap-fit ​​block. When the motor is started, the rotating seat rotates one revolution. The rolling blocks on the rotating seat roll away from the snap-fit ​​slots in the snap-fit ​​block, and then snap into the next snap-fit ​​slot as the rotating seat rotates. This causes the snap-fit ​​block to rotate at a fixed angle, which in turn causes the rotating disc to rotate at a fixed angle, bringing the bearing body under the cleaning brush, allowing the bearing body to be cleaned one by one.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a dust cleaning device for tapered roller bearings, including a workbench 1. A rotating disk 2 is rotatably connected to the top of the workbench 1 via a bearing. Four limiting grooves 3 are provided at equal angles on the top of the rotating disk 2. Several locking interfaces 4 are symmetrically provided on both sides of the limiting grooves 3. A sliding block 5 is slidably connected inside the limiting groove 3. Protrusions 6 are symmetrically fixedly installed on both sides of the sliding block 5, and the positions of the protrusions 6 and the locking interfaces 4 are corresponding. An adjusting bolt 7 is threadedly connected to the top of the sliding block 5. By providing the adjusting bolt 7, when the positioning block 8 is moved to a suitable position, the adjusting bolt 7 is turned to make the sliding block 5 move upward, so that the protrusions 6 are locked into the locking interfaces 4, thereby making it difficult for the positioning block 8 to slide on the top of the limiting groove 3, and at the same time, locking the positioning block 8 makes it difficult for the positioning block 8 to rotate.

[0015] The adjusting bolt 7 is located on the top surface of the sliding block 5 and is provided with a positioning block 8. Each positioning block 8 is fitted with a bearing body 9. An electric telescopic rod 10 is fixedly installed on one side of the top of the workbench 1. A top seat 11 is fixedly installed on the top of the electric telescopic rod 10. A motor 12 is fixedly installed on the side of the top seat 11 away from the electric telescopic rod 10. A cleaning brush 14 is fixedly installed at the output end of the motor 12, and the cleaning brush 14 is positioned corresponding to the bearing body 9. By using the electric telescopic rod 10, the electric telescopic rod 10 is controlled to descend so that the cleaning brush 14 is close to the bearing body 9. The motor 12 is started to make the cleaning brush 14 rotate, thus completing the cleaning of the bearing body 9.

[0016] The bottom of the top seat 11 is fixedly mounted on the surface of the motor 12 with an isolation cover 13, and the output end of the motor 12 extends through to the bottom of the isolation cover 13. The isolation cover 13 covers the surface of the cleaning brush 14. By providing the isolation cover 13, the dust on the surface of the bearing body 9 is blocked by the isolation cover 13, making it difficult for the dust to be absorbed by the staff and affecting the health of the staff.

[0017] A dust suction head 15 is fixedly installed on the inner wall of the isolation cover 13, and a fan 16 is fixedly installed on the top of the top seat 11. The input end of the fan 16 and the dust suction head 15 are connected through a duct, and the output end of the fan 16 is fixedly connected to a dust collection chamber 17. By providing the dust suction head 15 and starting the fan 16, the dust suction head 15 absorbs the dust swept off the surface of the bearing body 9 by the cleaning brush 14 and discharges it into the dust collection chamber 17, so as to avoid leaving it on the surface of the workbench 1 and realize the absorption of dust on the surface of the bearing body 9.

[0018] A locking block 21 is fixedly connected to the bottom of the rotating disk 2. The locking block 21 has locking grooves 22 at equal angles. A motor 2 18 is fixedly installed at the bottom of the worktable 1. A rotating seat 19 is fixedly connected to the output end of the motor 2 18. The locking block 21 overlaps the top edge of the rotating seat 19. A rolling block 20 is provided. The rolling block 20 rolls in the locking groove 22, which reduces the friction between the rolling block 20 and the locking block 21 and avoids wear on the locking block 21.

[0019] A rolling block 20 is rotatably connected to one side of the rotating seat 19 via a pin, and the rolling block 20 engages with the locking groove 22. With the rotating seat 19 provided, the rotating seat 19 rotates one revolution, causing the rolling block 20 to roll away from the locking groove 22 and roll into another locking groove 22, so that the locking block 21 completes the rotation at a fixed angle.

[0020] The working principle of this utility model is as follows: Select a suitable locating block 8 based on the size of the bearing body 9 and place it on top of the sliding block 5. Insert the adjusting bolt 7 through the locating block 8 and thread it onto the sliding block 5, allowing the sliding block 5 to slide into the limiting groove 3 to the appropriate position. Tighten the adjusting bolt 7 to move the sliding block 5 upwards, causing the protrusion 6 on the sliding block 5 to engage with the locking interface 4, preventing the locating block 8 from easily moving on top of the rotating disk 2. Simultaneously, the adjusting bolt 7 and the sliding block 5 secure the locating block 8, making it difficult for it to rotate. Place a batch of bearing bodies 9 onto the surface of the locating block 8. Control the electric telescopic rod 10 to descend, bringing the cleaning brush 14 closer to the bearing body 9. The isolation cover 13 covers the bearing. On the surface of the bearing body 9, the first motor 12 is started to rotate the cleaning brush 14 to clean the bearing body 9. At the same time, the fan 16 is started to make the suction head 15 absorb the dust cleaned off the bearing body 9 by the cleaning brush 14 into the suction chamber 17. After cleaning one bearing body 9, the second motor 18 is started to rotate the rotating seat 19 one revolution, causing the rolling block 20 to disengage from the locking groove 22. Then, as the rotating seat 19 rotates, the rolling block 20 is locked into the next locking groove 22, thereby driving the locking block 21 to rotate at a fixed angle, so that the next bearing body 9 is brought to the bottom of the cleaning brush 14 for cleaning. This completes the cleaning of a batch of bearing bodies 9.
