Abstract
Description
Technical Field
[0001] This application relates to the field of new energy battery production, and in particular to a roll bearing housing mounting device and a rolling equipment. Background Technology
[0002] In dry roller pressing equipment, due to the need for heating and high pressure, the bearing housing is typically cast in one piece to ensure its strength. However, existing roller pressing equipment usually tightens the bearing housing by drilling threaded holes in the bearing housing and using set screws to secure the top plate. Since the equipment needs to be heated during operation, heat transfer causes the screws to expand, damaging the threads on the bearing housing and affecting the long-term stability and service life of the equipment. Furthermore, in existing technology, the side of the bearing housing is limited by baffles, resulting in a large contact area. This leads to sliding friction during bearing housing movement, high frictional force, and the generation of metal debris, which not only increases equipment wear but may also adversely affect product quality.

[0039] See Figure 1 and Figure 2 As shown in the figure, this application provides a roll bearing housing mounting device, which includes a fixing frame 100, a gap adjustment assembly 300, and a carrier plate 400.
[0040] In some embodiments, the fixing frame 100 has a mounting cavity 110 for mounting the bearing housing 200. The mounting cavity 110 has a first pressing surface and a second pressing surface, which are arranged parallel to each other. The gap adjustment assembly 300 is located in the mounting cavity 110. A needle roller assembly 500 is disposed on the side of the gap adjustment assembly 300 facing the bearing housing 200. The gap adjustment assembly 300 is located between the needle roller assembly 500 and the first pressing surface. The carrier plate 400 is located in the mounting cavity 110. The carrier plate 400 is disposed on the second pressing surface. The needle roller assembly 500 is disposed on the side of the carrier plate 400 facing the bearing housing 200.
[0041] Please continue reading. Figure 1 and Figure 2As shown, the fixed frame 100 is rectangular, and the corresponding mounting cavity 110 is also rectangular. The first top pressing surface is the inner top surface of the mounting cavity 110, and the second top pressing surface is the inner bottom surface of the mounting cavity 110. The bearing seat 200 is located inside the mounting cavity 110. A needle roller assembly 500 is provided at both the upper and lower surfaces of the bearing seat 200. A carrier plate 400 is provided between the needle roller assembly 500 and the second top pressing surface of the fixed frame 100. The carrier plate 400 is used for mounting the lower needle roller assembly 500. A gap adjustment assembly 300 is provided between the upper needle roller assembly 500 and the first top pressing surface of the fixed frame 100. The gap adjustment assembly 300 is used to adjust the gap between the upper needle roller assembly 500 and the bearing seat 200, thereby enabling the gap between the bearing seat 200 and the needle roller assembly 500 to be adjusted.
[0042] Understandably, the needle roller assembly 500 can convert sliding friction into rolling friction. When the bearing housing 200 needs to be adjusted by moving in the radial direction, the needle roller assembly 500 at the upper and lower surfaces of the bearing housing 200 can convert sliding friction into rolling friction, reduce metal debris generated by sliding friction, and reduce equipment wear.
[0043] In this embodiment, when the bearing housing 200 needs to be installed, the carrier plate 400 is first fixedly installed on the second top pressure surface, then the needle roller assembly 500 is set on the carrier plate 400, the bearing housing 200 is placed on the needle roller assembly 500, the needle roller assembly 500 is set at the upper surface of the bearing housing 200, the gap adjustment assembly 300 is set between the needle roller assembly 500 and the first top pressure surface, and finally the gap adjustment assembly 300 is used to adjust the gap between the needle roller assembly 500 and the first top pressure surface and the gap between the needle roller assembly 500 and the bearing housing 200.
[0044] The gap adjustment assembly 300 includes a first top plate 310, a second top plate 320, and a fixing block 330. The first top plate 310 is located between the needle roller assembly 500 and the first pressing surface, and the second top plate 320 is disposed between the first top plate 310 and the first pressing surface. The contact surface between the first top plate 310 and the second top plate 320 is a wedge-shaped surface. The fixing block 330 is fixedly installed on the fixing frame 100, and at least one screwing component 340 is fixedly installed on the fixing block 330, and the screwing component 340 is connected to the second top plate 320.
[0045] See Figure 1 and Figure 2As shown, the contact surfaces of the first top plate 310 and the second top plate 320 are wedge-shaped. When the second top plate 320 is moved, the force is applied to the first top plate 310 under the action of the wedge-shaped surface, thereby driving the first top plate 310 to move downward. This further applies force to the needle roller assembly 500, thereby also driving the needle roller assembly 500 to move downward, thereby reducing the gap between the needle roller assembly 500 and the bearing seat 200. The needle roller assembly 500 and the upper surface of the bearing seat 200 are in full contact. The reaction force reduces the gap between the second top plate 320 and the first top pressing surface, thereby achieving gap adjustment.
[0046] Specifically, a fixing block 330 is fixedly installed on the side of the fixing frame 100. The fixing block 330 has a hole and a screwing component 340 in the hole. The screwing component 340 is screwed to the second top plate 320. When the screwing component 340 is screwed, it can drive the second top plate 320 to move, and the gap can be adjusted under the action of the wedge surface.
[0047] In order to accommodate the amount of movement of the second top plate 320 along the height direction, the hole through which the screwing member 340 passes is in the shape of a waist-shaped groove, so as to accommodate the amount of movement of the second top plate 320.
[0048] In another embodiment, the second top plate 320 can be fixedly installed on the first top pressing surface, the first top plate 310 can be moved, and then the screwing component 340 is connected to the first top plate 310. By screwing the screwing component 340, the first top plate 310 can be moved to cooperate with the wedge surface to achieve gap adjustment.
[0049] In this embodiment, the screwing component 340 is a bolt.
[0050] Positioning blocks 350 are provided on both sides of the first top plate 310. The first top plate 310 abuts against the positioning blocks 350, and the positioning blocks 350 are fixedly connected to the first top pressing surface.
[0051] Please continue reading. Figure 2 As shown, in order to prevent the first top plate 310 from moving along with the second top plate 320 during its movement, positioning blocks 350 are provided on both sides of the first top plate 310. The positioning blocks 350 on both sides limit the position of the first top plate 310 and prevent the first top plate 310 from moving along with the second top plate 320.
[0052] The first top plate 310 has a groove 311 on the side facing the positioning block 350, and the positioning block 350 has a protrusion 351 on the side facing the groove 311, and the protrusion 351 extends into the groove 311.
[0053] Please see Figure 3As shown, the positioning block 350 is fixedly connected to the first top pressing surface, specifically by bolt connection. The position of the first top plate 310 can be limited by the cooperation between the groove 311 and the protrusion 351, that is, the protrusion 351 is inserted into the groove 311 to limit the position.
[0054] The first top plate 310 has a first receiving groove 312 on the side facing the needle roller assembly 500.
[0055] See Figure 2 and Figure 3 As shown, in order to prevent the needle roller assembly 500 located at the first top plate 310 from moving, a first receiving groove 312 is formed on the bottom surface of the first top plate 310. It can be understood that the function of the first receiving groove 312 is to limit the position of the needle roller assembly 500 and prevent the needle roller assembly 500 from moving. In order to enable the needle roller assembly 500 to contact the upper surface of the bearing housing 200, the needle roller assembly 500 is at least partially located outside the first receiving groove 312.
[0056] The carrier plate 400 includes a plate body 410 fixedly installed on the second top pressure surface, and the plate body 410 has a second receiving groove 420 on the side facing the bearing seat 200.
[0057] See Figure 4 As shown, in order to prevent the needle roller assembly 500 from shifting position, a plate 410 is fixedly installed on the first pressing surface. The plate 410 can be fixed by bolt connection. A second receiving groove 420 is installed on the plate 410. The needle roller assembly 500 is placed in the second receiving groove 420. It can be understood that in order for the needle roller assembly 500 to contact the lower surface of the bearing housing 200, the needle roller assembly 500 needs to be partially located outside the second receiving groove 420.
[0058] The needle roller assembly 500 includes a mounting plate 510, on which a plurality of mounting slots 511 are provided, and each mounting slot 511 is provided with a needle roller 520.
[0059] See Figure 5 As shown, in order to convert sliding friction into rolling friction, needle rollers 520 are required. The rotation of the needle rollers 520 converts sliding friction into rolling friction. Specifically, multiple mounting grooves 511 are set at equal intervals on the upper surface of the mounting plate 510, and a needle roller 520 is installed in each needle roller 520. It can be understood that sliding friction can only be converted into rolling friction when the needle roller 520 is in contact with the object. Therefore, the diameter of the needle roller 520 should be greater than the thickness of the mounting plate 510, so that part of the needle roller 520 is exposed to the outside.
[0060] A first edge-blocking assembly 600 is fixedly installed on the fixed frame 100. The first edge-blocking assembly 600 includes a first fixing plate 610 fixedly installed on the fixed frame 100. The first fixing plate 610 has a first mounting hole 611. A first connecting rod 620 is fixedly installed in the first mounting hole 611. A first roller 630 is rotatably installed at the end of the first connecting rod 620 facing the bearing seat 200. A first groove is opened on the side of the bearing seat 200 facing the first top pressure surface. The first roller 630 is at least partially located in the first groove.
[0061] See Figure 1 and Figure 6 As shown, in order to prevent the bearing housing 200 from moving axially during radial movement, a first baffle assembly 600 is installed on the fixed frame 100. The first baffle assembly 600 limits the axial position of the bearing housing 200. Specifically, the first fixing plate 610 is first installed on the side wall of the fixed frame 100 with bolts. Then, the first connecting rod 620 is fixed by bolts through the first mounting hole 611. Finally, the first roller 630 at the end of the first connecting rod 620 is inserted into the first groove on the upper surface of the bearing housing 200. The position of the bearing housing 200 is limited by the contact between the first roller 630 and the inner wall of the first groove.
[0062] Understandably, in order to allow the first roller 630 to penetrate into the first groove, the first mounting hole 611 is shaped like an oblong groove, which allows for slight adjustments to the positions of the first connecting rod 620 and the first roller 630 to meet the installation requirements.
[0063] A second edge-blocking assembly 700 is fixedly installed on the fixed frame 100. The second edge-blocking assembly 700 includes a second fixing plate 710 fixedly installed on the fixed frame 100. The second fixing plate 710 has a second mounting hole 711. A second connecting rod 720 is fixedly installed in the second mounting hole 711. A second roller 730 is rotatably installed at the end of the second connecting rod 720 facing the bearing seat 200. A second groove is opened on the side of the bearing seat 200 facing the second top pressure surface. The second roller 730 is at least partially located in the second groove.
[0064] See Figure 1 and Figure 7As shown, similarly to the first retaining edge assembly 600, the second connecting rod 720 is fixedly installed in the second mounting hole 711 by means of a nut. Finally, the second roller 730 is inserted into the second groove on the bottom surface of the bearing seat 200. Finally, the second fixing plate 710 is fixedly installed on the side wall of the fixing frame 100 by means of bolts, so that the second roller 730 is always kept in the second groove. The position of the bearing seat 200 is defined by the contact between the second roller 730 and the inner wall of the second groove.
[0065] This application embodiment also provides a roll forming device, which includes a bearing housing 200 and a roll bearing housing mounting device as described in any of the above claims, wherein the bearing housing 200 is disposed in the mounting cavity 110 of the roll bearing housing mounting device.
