Description

Technical Field

[0001] This invention relates to the field of bearing auxiliary technology, and in particular to a bearing assembly auxiliary device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. When assembling the pinion bearing of a coal mill, the locking nut is tightened by striking it with a sledgehammer.

[0003] In the prior art, patent document CN218518543U discloses an auxiliary device for bearing assembly, relating to the field of bearing assembly equipment technology. This device includes an auxiliary assembly mechanism. A hydraulic cylinder is fixedly connected to the bottom of an upper support frame. A piston rod is fixedly connected to the output shaft end of the hydraulic cylinder. An auxiliary screw is provided at the bottom end of the piston rod. The piston rod is detachably connected to a bearing clamping and disassembly assembly via the auxiliary screw. The bearing clamping and disassembly assembly detachably clamps the bearing assembly on its inner side. This device quickly and effectively positions the bearing and the mounting shaft, facilitating the installation and disassembly of the small gear bearing in the coal mill. It ensures controllable bearing clearance, improves bearing life, reduces equipment failure rate and labor intensity, increases bearing assembly and disassembly efficiency, facilitates movement and placement, and minimizes the risk of excessive bearing vibration due to loose installation or the inability to disassemble the bearing due to excessive tight installation, thus reducing the frequency of bearing damage.

[0004] The existing technology has the following problems: When assembling the pinion bearing of a coal mill, the bearing is installed by striking it with a sledgehammer. However, the current method requires one employee to lift the bearing to ensure it is level with the equipment, and another employee to strike the support to install it into the equipment. However, the bearing is heavy, and manual handling requires maintaining a level and height. The weight causes slight wobbling, preventing the bearing from being perfectly level with the equipment. This slight tilt makes it difficult to force the bearing into place, and the bearing surface may be damaged by impact. Furthermore, the use of a hammer to strike the bearing during the assembly of the silicon steel pretreatment brush roller bearing seat is difficult to control, easily damaging the bearing and injuring hands. This reduces work efficiency and poses a serious safety hazard. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problems in the prior art where manual handling of bearings cannot always keep them on the same horizontal plane due to gravity, the bearings are too heavy and wobble slightly up and down during handling, and the bearings cannot be aligned and cannot be installed into the equipment due to impact.

[0006] To solve the above-mentioned technical problems, the present invention provides a bearing assembly auxiliary device.

[0007] In one embodiment of the present invention, it includes:

[0008] The bearing assembly clamp is movably fitted onto one end surface of the bearing assembly auxiliary cylinder.

[0009] The assembly auxiliary cylinder support rod is movably fitted onto the outer surface of the bearing assembly auxiliary cylinder.

[0010] A docking anti-slip unit is fixedly connected to the outer surface of the bearing assembly clamp joint. The docking anti-slip unit includes a docking limit rod and an arc-shaped extrusion strip. An extrusion positioning unit is fixedly connected to the inner surface of the bearing assembly clamp joint. The extrusion positioning unit includes a fixing strip and a swing arc plate.

[0011] In one embodiment of the present invention, a heightening support unit is slidably sleeved on the inner surface of the assembly auxiliary cylinder heightening rod. The heightening support unit includes a support leg and a pressing leg. A spacing adjustment unit is fixedly connected to both sides of the assembly auxiliary cylinder heightening rod. The spacing adjustment unit includes a limit handle, a threaded rod, and a pressing threaded plate.

[0012] A docking positioning unit is movably sleeved on the top surface of the assembly auxiliary cylinder raising rod. The docking positioning unit includes a docking slot and a docking rod.

[0013] In one embodiment of the present invention, one end of the docking limiting rod is fixedly connected to the left side surface of the bearing assembly clamp joint, and the position of the docking limiting rod is set at the periphery of the left side surface of the bearing assembly clamp joint. Threaded holes are opened on both sides of the bearing assembly clamp joint and at the right edge position. One side surface of the fixing strip is fixedly connected to the inner wall surface of the bearing assembly clamp joint, and one side surface of the swing arc plate is fixedly connected to the outer side surface of the fixing strip.

[0014] In one embodiment of the present invention, an impact block is fixedly connected to one left end of the bearing assembly auxiliary cylinder, and a support rod is fixedly connected to the top surface of the bearing assembly auxiliary cylinder. A semi-circular mating groove is formed on the outer surface of the bearing assembly auxiliary cylinder at the right edge. After the bearing is installed, the mating limiting rod on one end surface of the bearing assembly clamp is engaged into the interior of the semi-circular mating groove. Multiple semi-circular mating grooves are used to limit the position of the bearing assembly clamp. During impact installation, another employee can install the new bearing into the interior of the bearing assembly clamp. After the previous bearing is installed, the bearing assembly auxiliary cylinder is directly detached from the surface of the mating limiting rod and directly installed onto the surface of the new bearing assembly clamp, continuing to the next device. The installation process significantly reduces installation time and improves work efficiency. A snap-fit ​​slot is provided on the right side surface of the bearing assembly auxiliary cylinder. One end of the arc-shaped extrusion strip is movably fitted onto the inner surface of the snap-fit ​​slot. The arc-shaped extrusion strip is positioned on the inner surface of the bearing assembly snap-fit ​​joint. When assembling the bearing, first observe the bearing height to determine if an assembly auxiliary cylinder shim is needed. If not, directly snap the bearing onto the inner surface of the bearing assembly snap-fit ​​joint, using the arc-shaped extrusion strip to press against the bearing surface, thus fixing the bearing in the center position inside the bearing assembly snap-fit ​​joint. A threaded rotating rod is movably fitted onto the inner surface of the threaded hole, and one end of the threaded rotating rod is movably fitted onto the outer surface of the swinging arc plate.

[0015] In one embodiment of the present invention, a limiting cylinder is fixedly connected to the outer surface of the swinging arc plate and movably sleeved on one end of the threaded rotating rod. An elastic strip is fixedly connected to the inner surface of the swinging arc plate. An arc-shaped flexible plate is fixedly connected to the outer surface of the elastic strip. An anti-slip strip is fixedly connected to the outer surface of the arc-shaped flexible plate. The anti-slip strip on the inner surface of the arc-shaped flexible plate is tightly attached to the surface of the bearing. Multiple anti-slip strips increase the anti-slip force between the bearing and the bearing surface. The elastic strip deforms when compressed, thereby effectively clamping some larger bearings.

[0016] In one embodiment of the present invention, a slot is provided at the middle position of both sides of the assembly auxiliary cylinder raising rod, and a limit locking post is fixedly connected to both sides of the assembly auxiliary cylinder raising rod and at the two ends of the slot. The outer surface of the pressing threaded plate is movably overlapped with the inner wall of the assembly auxiliary cylinder raising rod, and the outer surface of the support leg is movably sleeved on the inner surface of the assembly auxiliary cylinder raising rod.

[0017] In one embodiment of the present invention, one end of the limiting handle is fixedly connected to the surface of the support leg and located at the top edge, and both ends of the pressing threaded plate and one end of the limiting handle extend through the slot to the outer wall. An elastic wire is fixedly connected to the bottom surface of the pressing threaded plate and disposed on the top outer surface of the support leg. The sliding length of the pressing threaded plate is used to increase the distance between the assembly auxiliary cylinder shim and the support leg. When the bearing is too heavy and placed on the ground, the elastic wire and elastic soft block can be used to elastically buffer the fall of the bearing.

[0018] In one embodiment of the present invention, the inner surface of the limiting snap-fit ​​post and the limiting handle on the left side is movably sleeved on the outer surface of the threaded rod II, the inner wall surface of the left end of the pressing threaded plate is threadedly sleeved on the outer surface of the threaded rod II, and the inner wall surface of the limiting snap-fit ​​post, the limiting handle and the pressing threaded plate on the right side is movably sleeved with a limiting rod.

[0019] In one embodiment of the present invention, limiting grooves are formed on the inner walls of both sides of the support leg, and elastic blocks are fixedly connected to the bottom surface of the support leg. The bottom surface of the elastic blocks is fixedly connected to the top surface of the lower pressure leg, and the lower pressure leg overlaps on the ground. The length of the lower pressure leg and the assembly auxiliary cylinder shim rod is used to limit the height of the bearing, which reduces the need for employees to keep the bearing suspended after the bearing assembly auxiliary cylinder is engaged. Moreover, the support of the assembly auxiliary cylinder shim rod can also keep the bearing and the equipment interface at a horizontal angle, which is convenient for subsequent installation. Limiting strips that are movably sleeved on the inner wall of the limiting groove are fixedly connected to the two sides of the lower pressure leg.

[0020] In one embodiment of the present invention, a downward pressing arc plate is movably sleeved on the top surface of the assembly auxiliary cylinder shim. The top surface of the assembly auxiliary cylinder shim and the bottom surface of the downward pressing arc plate are respectively provided with a docking slot and a docking rod. When the equipment to be installed is high, the assembly auxiliary cylinder shim is aligned with the surface of the bearing assembly auxiliary cylinder. The docking slot and docking rod on one side of the downward pressing arc plate are aligned with the docking slot and docking rod on the top surface of the assembly auxiliary cylinder shim to define its position. A limit post is provided on the right side surface of the assembly auxiliary cylinder shim and the downward pressing arc plate. A threaded block is fixedly connected to the top left surface of the assembly auxiliary cylinder shim. A threaded rod is movably sleeved on the left side surface of the downward pressing arc plate. The threaded rod is then rotated on the inner surface of the threaded block to tightly clamp the downward pressing arc plate onto the top surface of the assembly auxiliary cylinder shim, thus connecting the assembly auxiliary cylinder shim and the bearing assembly auxiliary cylinder.

[0021] The technical solution of the present invention has the following advantages compared with the prior art:

[0022] The bearing assembly auxiliary device described in this invention, in conjunction with the lower pressure leg, rests on the ground. By utilizing the length of the lower pressure leg and the assembly auxiliary cylinder support rod, the height of the bearing is limited. This reduces the need for employees to continuously lift and suspend the bearing after it has been clamped in the assembly auxiliary cylinder. Furthermore, the support of the assembly auxiliary cylinder support rod ensures that the bearing interface with the equipment remains at a horizontal angle, facilitating the installation of the bearing into the equipment even under subsequent impact.

[0023] The bearing assembly auxiliary device of this invention directly clamps the bearing onto the inner surface of the bearing assembly clamping joint. An arc-shaped extrusion strip presses against the bearing surface, thus fixing the bearing at the center position inside the bearing assembly clamping joint. A threaded rotating rod rotates inside a threaded hole, pressing a swinging arc plate on the outer surface of the fixing strip towards the center position. Anti-slip strips on the inner surface of the arc-shaped flexible plate tightly adhere to the bearing surface, increasing the anti-slip force between the anti-slip strips and the bearing surface. The elastic flexible strip deforms during the extrusion process, effectively clamping larger bearings.

[0024] The bearing assembly auxiliary device of the present invention, when the height of the equipment is higher than the length of the assembly auxiliary cylinder support rod, rotates the threaded rod two to make the lower threaded plate slide downward on the inner surface of the assembly auxiliary cylinder support rod. The sliding length of the lower threaded plate is used to increase the distance between the assembly auxiliary cylinder support rod and the support leg. When the bearing is too heavy and placed on the ground, the elastic wire and elastic soft block can be used to elastically buffer the bearing's fall.

[0025] The bearing assembly auxiliary device of the present invention, when the equipment to be installed is high, connects the assembly auxiliary cylinder shim rod to the surface of the bearing assembly auxiliary cylinder, and aligns the mating slot and mating rod on one side surface of the lower pressure arc plate with the mating slot and mating rod on the top surface of the assembly auxiliary cylinder shim rod to define its position. Then, rotate the threaded rod on the inner surface of the threaded block to tightly clamp the lower pressure arc plate onto the top surface of the assembly auxiliary cylinder shim rod, thus connecting the assembly auxiliary cylinder shim rod and the bearing assembly auxiliary cylinder.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0042] Reference Figure 1 As shown, this invention provides a bearing assembly auxiliary device.

[0043] like Figure 1 As shown, including:

[0044] The bearing assembly clamp 12 is movably sleeved on one end surface of the bearing assembly auxiliary cylinder 11.

[0045] The assembly auxiliary cylinder padding rod 13 is movably sleeved on the outer surface of the bearing assembly auxiliary cylinder 11.

[0046] A docking anti-slip unit is fixedly connected to the outer surface of the bearing assembly clamp 12. The docking anti-slip unit includes a docking limit rod 121 and an arc-shaped extrusion soft strip 125. An extrusion positioning unit is fixedly connected to the inner surface of the bearing assembly clamp 12. The extrusion positioning unit includes a fixing strip 122 and a swing arc plate 123.

[0047] like Figure 4 - Figure 7 As shown, a support unit is slidably sleeved on the inner surface of the assembly auxiliary cylinder raising rod 13. The support unit includes a support leg 138 and a lower pressing leg 1311. Spacing adjustment units are fixedly connected to both sides of the assembly auxiliary cylinder raising rod 13. The spacing adjustment unit includes a limit handle 133, a threaded rod 134 and a lower pressing threaded plate 136.

[0048] A docking positioning unit is movably sleeved on the top surface of the assembly auxiliary cylinder pad rod 13. The docking positioning unit includes a docking slot c3 and a docking rod c4.

[0049] like Figure 2 As shown, one end of the docking limiting rod 121 is fixedly connected to the left side surface of the bearing assembly clamp 12, and the docking limiting rod 121 is positioned around the left side surface of the bearing assembly clamp 12. Threaded holes are provided on both sides of the bearing assembly clamp 12, specifically at the right edge. One side surface of the fixing strip 122 is fixedly connected to the inner wall of the bearing assembly clamp 12, and one side surface of the swing arc plate 123 is fixedly connected to the outer surface of the fixing strip 122. The swing arc plate 123 on the outer surface of the fixing strip 122 is then rotated within the threaded holes by the threaded rotating rod 124, causing the swing arc plate 123 on the outer surface of the fixing strip 122 to move towards the center. The bearing is pressed by an arc-shaped extrusion strip 125, which is positioned on the inner surface of the bearing assembly clip 12. When assembling the bearing, the height of the bearing is first observed to see if the assembly auxiliary cylinder shim 13 needs to be installed. If not, the bearing is directly clipped onto the inner surface of the bearing assembly clip 12, and the arc-shaped extrusion strip 125 is used to press the surface of the bearing, thereby fixing the bearing in the center position inside the bearing assembly clip 12. A threaded rotating rod 124 is threadedly and movably sleeved on the inner surface of the threaded hole, and one end of the threaded rotating rod 124 is movably sleeved on the outer surface of the swing arc plate 123.

[0050] like Figure 2 As shown, an impact block 111 is fixedly connected to one left end of the bearing assembly auxiliary cylinder 11, and a support rod 112 is fixedly connected to the top surface of the bearing assembly auxiliary cylinder 11. When the support rod 112 is raised by the worker, the bearing is aligned with the surface of the equipment to be clamped, and the impact block 111 is struck, thereby clamping the bearing into the equipment. A semi-circular mating groove 113 is provided on the outer surface of the bearing assembly auxiliary cylinder 11, located at the right edge. After the bearing is installed, the mating limiting rod 121 on one end surface of the bearing assembly clamping connector 12 is clamped into the semi-circular mating groove 113. Multiple semi-circular mating grooves 113 are used to... The position of the bearing assembly clamp 12 is defined. During impact installation, another employee can install the new bearing into the bearing assembly clamp 12. After the previous bearing is installed, the bearing assembly auxiliary cylinder 11 can be directly detached from the surface of the docking limit rod 121 and installed directly onto the surface of the new bearing assembly clamp 12 to continue installing the next piece of equipment. This greatly reduces the time spent on installation and speeds up the work. The right side surface of the bearing assembly auxiliary cylinder 11 is provided with a clamping slot 114, and one end of the arc-shaped extrusion strip 125 is movably sleeved on the inner surface of the clamping slot 114.

[0051] like Figure 3 As shown, a limiting sleeve a1 is fixedly connected to the outer surface of the swing arc plate 123 and movably sleeved on one end of the threaded rotating rod 124. An elastic soft strip a2 is fixedly connected to the inner surface of the swing arc plate 123. An arc-shaped soft plate a3 is fixedly connected to the outer surface of the elastic soft strip a2. An anti-slip strip a4 is fixedly connected to the outer surface of the arc-shaped soft plate a3. The anti-slip strip a4 on the inner surface of the arc-shaped soft plate a3 is tightly attached to the surface of the bearing. Multiple anti-slip strips a4 increase the anti-slip force between the bearing and the bearing surface. The elastic soft strip a2 deforms when compressed, thereby effectively clamping some larger bearings.

[0052] like Figure 4 - Figure 7As shown, slots 131 are provided at the middle positions on both sides of the assembly auxiliary cylinder support rod 13. Limiting locking posts 132 are fixedly connected to the two side surfaces of the assembly auxiliary cylinder support rod 13 and at the two end edges of the slots 131. The outer surface of the pressing threaded plate 136 movably overlaps the inner wall of the assembly auxiliary cylinder support rod 13. The outer surface of the support leg 138 movably sleeves the inner surface of the assembly auxiliary cylinder support rod 13. One end of the limiting handle 133 is fixedly connected to the surface of the support leg 138 and is located at the top edge. The two ends of the pressing threaded plate 136 and the limiting handle 133 are connected to each other. One end extends through the slot 131 to the outer wall. An elastic wire 137, located on the top outer surface of the support leg 138, is fixedly connected to the bottom surface of the pressing threaded plate 136. The sliding length of the pressing threaded plate 136 increases the distance between the assembly auxiliary cylinder shim 13 and the support leg 138. When the bearing is too heavy and placed on the ground, the elastic wire 137 and elastic soft block 1310 can provide elastic cushioning against the bearing's descent. The inner surfaces of the left limiting locking post 132 and the limiting handle 133 are movably sleeved on the outer surface of the threaded rod 134. The pressing threaded plate 136... The inner wall of the left end of 36 is threaded onto the outer surface of the threaded rod 134. If the height of the equipment is higher than the length of the assembly auxiliary cylinder support rod 13, rotating the threaded rod 134 causes the pressing threaded plate 136 to slide downward on the inner surface of the assembly auxiliary cylinder support rod 13. The right limit locking post 132, the limit handle 133, and the inner wall of the pressing threaded plate 136 are movably fitted with the limit rod 135. Limit grooves 139 are opened on the inner walls of both sides of the support leg 138. An elastic soft block 1310 is fixedly connected to the bottom surface of the support leg 138. The bottom of the elastic soft block 1310... The bearing is fixedly connected to the top surface of the lower pressure leg 1311 and rests on the ground in conjunction with the lower pressure leg 1311. The length of the lower pressure leg 1311 and the assembly auxiliary cylinder shim 13 is used to limit the height of the bearing, which reduces the need for employees to constantly lift and suspend the bearing after the bearing assembly auxiliary cylinder 11 is engaged. Moreover, the support of the assembly auxiliary cylinder shim 13 can keep the bearing and the equipment interface at a horizontal angle, which is convenient for subsequent installation. Limiting slide bars 1312 are fixedly connected to the two sides of the lower pressure leg 1311 and are movably sleeved on the inner wall of the limiting slide groove 139.

[0053] like Figure 5 - Figure 6As shown, a downward pressure arc plate c2 is movably sleeved on the top surface of the assembly auxiliary cylinder shim 13. A mating slot c3 and a mating rod c4 are respectively provided on the top surface of the assembly auxiliary cylinder shim 13 and the bottom surface of the downward pressure arc plate c2. When the equipment to be installed is relatively high, the assembly auxiliary cylinder shim 13 is aligned with the surface of the bearing assembly auxiliary cylinder 11. The mating slot c3 and mating rod c4 on one side surface of the downward pressure arc plate c2 are aligned with the mating slot c3 and mating rod c4 on the top surface of the assembly auxiliary cylinder shim 13. Next, the position is defined. A limit post c5 is set on the right side surface of the assembly auxiliary cylinder shim 13 and the lower pressure arc plate c2. A threaded block c1 is fixedly connected to the top left surface of the assembly auxiliary cylinder shim 13. A threaded rod c6 is movably sleeved on the left side surface of the lower pressure arc plate c2. Then, the threaded rod c6 is rotated on the inner side surface of the threaded block c1, so that the lower pressure arc plate c2 is tightly clamped to the top surface of the assembly auxiliary cylinder shim 13, thus connecting the assembly auxiliary cylinder shim 13 and the bearing assembly auxiliary cylinder 11.

[0054] The working principle of this auxiliary loading and unloading device will be explained in detail below.

[0055] When assembling bearings, first observe the bearing height to see if an assembly auxiliary cylinder shim rod 13 is needed. If not, directly snap the bearing onto the inner surface of the bearing assembly snap-fit ​​joint 12. Use the arc-shaped extrusion strip 125 to press the bearing surface, thereby fixing the bearing in the center position inside the bearing assembly snap-fit ​​joint 12. Then, rotate the threaded rotating rod 124 inside the threaded hole to press the swing arc plate 123 on the outer surface of the fixing strip 122 towards the center position. Use the anti-slip strip a4 on the inner surface of the arc-shaped soft plate a3 to tightly adhere to the bearing surface. Use multiple anti-slip strips a4 to increase the anti-slip force between the bearing and the bearing surface. Then, use the elastic soft strip a2 to deform during extrusion, thereby effectively snapping together some larger bearings.

[0056] After the bearing is installed, the mating limit rod 121 on one end surface of the bearing assembly clamp 12 is engaged into the interior of the semi-circular mating groove 113. The position of the bearing assembly clamp 12 is limited by multiple semi-circular mating grooves 113. With the help of the workers, the support rod 112 is raised, the bearing is aligned with the surface of the equipment to be clamped, and the impact block 111 is impacted to clamp the bearing into the equipment. During impact installation, another worker can install the new bearing into the interior of the bearing assembly clamp 12. After the previous bearing is installed, the bearing assembly auxiliary cylinder 11 is directly detached from the surface of the mating limit rod 121 and installed directly onto the surface of the new bearing assembly clamp 12 to continue installing the next piece of equipment. This greatly reduces the time spent on installation and speeds up the work efficiency.

[0057] When the equipment to be installed is high, the assembly auxiliary cylinder shim 13 is aligned with the surface of the bearing assembly auxiliary cylinder 11. The mating slots c3 and c4 on one side of the pressure arc plate c2 are aligned with the mating slots c3 and c4 on the top surface of the assembly auxiliary cylinder shim 13 to define their positions. Then, the threaded rod c6 is rotated on the inner surface of the threaded block c1 to tightly clamp the pressure arc plate c2 onto the top surface of the assembly auxiliary cylinder shim 13, thus connecting the assembly auxiliary cylinder shim 13 and the bearing assembly auxiliary cylinder 11.

[0058] With the lowering leg 1311 overlapping on the ground, the length of the lowering leg 1311 and the assembly auxiliary cylinder shim 13 is used to limit the height of the bearing. This reduces the need for workers to constantly lift and suspend the bearing after the bearing assembly auxiliary cylinder 11 is engaged. In addition, the support of the assembly auxiliary cylinder shim 13 can keep the bearing and the equipment interface at a horizontal angle, which is convenient for subsequent installation.

[0059] If the height of the equipment is higher than the length of the assembly auxiliary cylinder support rod 13, the threaded rod 134 is rotated to make the lower threaded plate 136 slide downward on the inner surface of the assembly auxiliary cylinder support rod 13. The sliding length of the lower threaded plate 136 is used to increase the distance between the assembly auxiliary cylinder support rod 13 and the support leg 138. When the bearing is too heavy and placed on the ground, the elastic wire 137 and the elastic soft block 1310 can be used to elastically buffer the fall of the bearing.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
