Description

Technical Field

[0001] The invention relates to the technical field of bearing parts processing, in particular to a bearing ring processing device. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The basic structure of a bearing consists of four parts: an inner ring, an outer ring, a rolling element, and a cage. When processing the inner and outer rings of the bearing, the bearing ring needs to be rust-proofed, that is, a layer of oil film is distributed on the surface of the bearing ring to protect the bearing ring for the next assembly process.

[0003] Existing bearing ring anti-rust processes usually include immersion, brushing and spraying. When the bearing ring is rust-proofed by immersion, the bearing ring is usually placed in a container, and then the container containing the bearing ring is completely immersed in grease. However, since the bearing rings are stacked inside the container, it takes a long time for the bearing rings in the container to be soaked in grease, which affects the processing efficiency of the bearing rings.

When the driving mechanism drives the supporting frame to move up and down inside the oil tank, the rotating main shaft in the pushing structure rotates synchronously, and the containing frame can be pushed to the right intermittently through four push rods and sleeves. In this process, it cooperates with the push-back assembly to enable the containing frame to move back and forth left and right when it moves down into the anti-rust oil. At the same time, the rotation of the pushing structure can also cause the anti-rust oil in the oil tank to circulate, which is conducive to the anti-rust oil quickly wrapping the bearing ring and effectively shortening the oil immersion time of the bearing ring.

[0014] 2. The present invention installs an adjustment component. When the bearing ring is immersed in oil, the support component lifts the containing frame by a certain distance to separate the containing frame from the anti-rust oil. The user moves the position of the secondary gear upward through the adjustment component to separate the secondary gear from the main gear. At this time, the driving mechanism can only drive the pushing structure to operate. The pushing structure cooperates with the push-back component to make the upper side of the anti-rust oil of the containing frame move back and forth left and right, which is conducive to the containing frame directly discharging excess anti-rust oil in the oil tank, preventing a large amount of anti-rust oil from dripping when the containing frame is lifted out of the oil tank, thereby reducing the consumption of anti-rust oil.

[0024] The working principle capable of improving the oil immersion efficiency of the bearing ring is as follows: first, the containing frame 4 containing the bearing ring is hoisted into the oil tank 1 through the hoisting mechanism, and the supporting frame 301 supports the containing frame 4 through the supporting side plate 10, and then the driving motor 702 is controlled to operate, and the driving motor 702 drives the rotating main shaft 501 to rotate, and at the same time, the reciprocating screw 303 is driven to rotate through the main gear 701, the sub-gear 704, the second synchronous wheel 705 and the second synchronous belt 706. The rotation of the reciprocating screw 303 can drive the supporting frame 301 to move up and down in the oil tank 1, and the supporting frame 301 supports the containing frame 4 to move down. During the process of entering the anti-rust oil, the rotating main shaft 501 drives the four push rods 503 and the sleeve 504 to rotate. The four push rods 503 intermittently push the containing frame 4 to the left during the rotation. In this process, with the elastic performance of the spring 602 itself, the containing frame 4 can move back and forth left and right. In the process of the support frame 301 driving the containing frame 4 to move downward, the containing frame 4 moves back and forth left and right on the support frame 301. At the same time, the rotating main shaft 501 drives the push rods 503 to rotate, which can make the anti-rust oil in the oil tank 1 circulate, thereby facilitating the anti-rust oil to quickly wrap the bearing ring, and effectively shortening the oil immersion time of the bearing ring.

[0025] Embodiment 2

[0026] See also Figure 8 The present embodiment further explains Example 1. An adjusting assembly 8 is installed between the second synchronous wheel 705 installed on the lower side of the sub-gear 704 and the sub-gear 704. The adjusting assembly 8 includes a rectangular column 801 fixedly embedded in the center of the upper end of the second synchronous wheel 705 at the lower end of the sub-gear 704. A sleeve 802 is movably sleeved on the outer side of the rectangular column 801, and the sub-gear 704 is fixedly sleeved on the outer side of the sleeve 802. Four top beads 803 equidistantly distributed on the circumference are movably embedded on the inner wall of the sleeve 802, and the top beads 803 can move left and right inside the sleeve 802.

[0027] See also Figure 8The top ball 803 is located inside the sleeve 802, and one end of the top ball 803 is fixedly embedded with a V-shaped spring piece 804, and the end of the V-shaped spring piece 804 is fixedly connected to the sleeve 802. Two rows of spherical grooves 805 equidistantly distributed on the circumference are opened on the side wall of the rectangular column 801, and the top ball 803 is movably connected to the rectangular column 801 through the spherical grooves 805. The top of the rectangular column 801 is fixedly sleeved with a limiting top cap 806, and the outer wall of the sleeve 802 is located on the upper side of the sub-gear 704 and is fixedly sleeved with a shift ring 807.

[0028] In this embodiment: after the bearing ring driven by the containing frame 4 is completely immersed in the anti-rust oil, the user stops driving the motor 702. Under the condition that the sleeve 802 and the rectangular column 801 are movably connected, the user moves the sleeve 802 and the secondary gear 704 upward through the dial ring 807. When the secondary gear 704 moves up and completely disengages from the main gear 701, the top ball 803 will be stuck in the first row of spherical grooves 805 on the rectangular column 801. At this time, the driving motor 702 is controlled to run, and the driving motor 702 can only drive the rotating main shaft 501 to rotate. This helps the containing frame 4 to move back and forth in the anti-rust oil without changing its height, thereby accelerating the grease wrapping around the bearing ring. Similarly, after the bearing ring is immersed in oil, the support frame 301 lifts the containing frame 4 away from the anti-rust oil, and the user again adjusts the component 8 to disengage the secondary gear 704 from the main gear 701, so that the containing frame 4 can move back and forth on the upper side of the anti-rust oil, which helps the containing frame 4 to directly discharge excess anti-rust oil in the oil tank 1, thereby preventing a large amount of anti-rust oil from dripping when the containing frame 4 is lifted out of the oil tank 1, thereby reducing the consumption of the anti-rust oil.

[0029] Embodiment 3

[0030] See also Figure 6 , this embodiment further explains other embodiments, the upper end of the support frame 301 is located on the outer side of the support side plate 10 and is installed with two symmetrically distributed limit components 9, the limit component 9 includes a mounting seat 901 fixedly connected to the support frame 301, and a limit plate 902 is installed on the mounting seat 901, and a side end surface of the limit plate 902 facing the support side plate 10 is movably embedded with a plurality of groups of second balls 904 distributed at equal distances, and the connection method between the second balls 904 and the support side plate 10 is a rolling connection, and two symmetrically distributed connecting shafts 903 are fixedly embedded on the outer side of the limit plate 902, and two symmetrically distributed fixing bolts 905 are threadedly installed on the limit plate 902 near its two ends, and the connection method between the fixing bolts 905 and the support frame 301 is a threaded connection.

[0031] In this embodiment: after the containing frame 4 is embedded in the supporting frame 301, the user rotates the limiting plate 902 so that the limiting plate 902 covers the upper side of the supporting side plate 10, and then positions the limiting plate 902 by fixing the bolts 905, which can prevent the containing frame 4 from tilting during the reciprocating movement to the left and right.
