Description

Technical Field

[0001] The utility model relates to the technical field of bearing maintenance, in particular to a portable bearing repair tool. Background Art

[0002] Bearings are a vital component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The steel balls inside the bearings will wear out when used for a long time. Therefore, the worn steel balls inside the bearings need to be replaced when the bearings are used for a long time. When the staff repair and replace the steel balls in the bearings, they need to use repair tools. The existing repair tools have solved the technical disadvantages of the inconvenience of the staff in disassembling them, but in actual use, repair tools with similar structures still have many defects. For example, they do not have the function of monitoring the pulling force of the bearings during the repair and disassembly process, so that the pulling force of the repair tool when disassembling the bearings is too large, which will aggravate the damage to the bearings and even cause the bearings to be completely scrapped, resulting in poor safety of the tools when used. For this reason, we have designed a portable bearing repair tool to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5 The utility model provides a technical solution: a portable bearing repair tool, comprising a main body mechanism 1 and a disassembly mechanism 2 assembled inside the main body mechanism 1, the main body mechanism 1 comprises a main disk body 101, the outer side of the main disk body 101 is provided with three sets of sliding holes 102, the interiors of the three sets of sliding holes 102 are all slidably mounted with fixed screws 303, the outer walls of the three sets of fixed screws 303 are threadedly mounted with fixed nuts 304, the bottoms of the three sets of fixed screws 303 are all fixedly mounted with pull rods 3, the bottoms of the three sets of pull rods 3 are all fixedly mounted with retractors 301, and the front of the main disk body 101 is fixedly mounted. There is a display screen 103, and a threaded sleeve 105 is fixedly installed at the central position of the main disk body 101. The disassembly mechanism 2 includes a threaded rod 201 and a push plate 4. A threaded hole 208 is provided at the bottom of the threaded rod 201, and an assembly screw 401 used in conjunction with the threaded hole 208 is fixedly installed on the top of the push plate 4. A rotating seat 202 is fixedly installed on the top of the threaded rod 201, and a rotating rod 204 is slidably installed inside the rotating seat 202. Both ends of the rotating rod 204 are provided with a gripping sleeve 206, and a pressure sensor 207 is fixedly installed at the bottom of the inside of the threaded rod 201.

[0021] Based on the above-mentioned structural setting, the portable bearing repair tool consists of a main body mechanism 1 and a disassembly mechanism 2, wherein the main body mechanism 1 is an overall support mechanism for the tool during operation, with the help of the main body mechanism 1, it can be connected to the outside of the outer ring of the bearing; the disassembly mechanism 2 is a support mechanism for the inner ring of the bearing, with the help of the disassembly mechanism 2, the axis can be disassembled when repairing. Specifically, during the working process, the hooks 301 at the bottom of the three groups of pull rods 3 are hung and connected with the bottom of the outer ring of the bearing, and the fixed screw 303 is slidably installed in the sliding hole 102 to movably connect the pull rod 3 and the main disk body 101, and the fixed screw 303 moves in the sliding hole 102. The adjustment can be used to expand and contract the pull rod 3 and the hook 301, so that the hook 301 can be used to hang and connect the outer rings of bearings of different sizes. The fixing nut 304 can lock the fixing screw 303 to ensure the stability of the pull rod 3 and the hook 301 during operation. The threaded rod 201 is bolted into the threaded sleeve 105 at the center of the main disk body 101. The assembly screw 401 is bolted into the threaded hole 208. The push plate 4 can be installed at the bottom of the threaded rod 201. When the threaded rod 201 rotates in the threaded sleeve 105, the push plate 4 can be raised and lowered. When the push plate 4 descends, it will conflict with the top of the bearing inner ring. The specifications of the push plate 4 can be matched and replaced according to the size of the repaired bearing. When the three sets of hooks 301 are hung and connected with the bottom of the outer ring of the bearing, the push plate 4 contacts the top of the inner ring of the bearing, and the staff rotates the threaded rod 201 to disassemble and separate the inner and outer rings of the bearing, thereby facilitating the staff to repair and replace the worn steel balls in the bearing, increasing the convenience of the staff when repairing the bearing. The rotating seat 202 cooperates with the rotating rod 204 to facilitate the staff to rotate the threaded rod 201 with ease, reducing the physical burden of the staff when repairing and disassembling the bearing with tools, and the holding sleeve 206 increases the staff's rotation The stability and comfort of the rod 204 when held prevents the staff from losing their hands when operating the rotating rod 204. The pressure sensor 207 can monitor the pressure of the push plate 4 on the inner ring of the bearing when it is disassembled, and the pressure sensor 207 is connected to the display screen 103 on the front of the main disk body 101 through a wire. The staff can view and understand the data detected by the pressure sensor 207 according to the display screen 103, avoiding the situation where the tool has excessive pulling force when disassembling the bearing, aggravating its damage or even completely scrapping it. Therefore, the safety of the staff when repairing and disassembling the bearing with the tool is increased, and the stability of the tool when disassembling the bearing is improved.

[0022] Furthermore, a battery cover 106 is fixedly mounted on one side of the main body 1, and a battery 107 is fixedly mounted inside the battery cover 106. The battery cover 106 can be installed and protected to protect the battery 107, and the battery 107 can power the tool during operation, thereby facilitating the tool to monitor the pulling force when removing the bearing.

[0023] Furthermore, a locking shaft 203 is threadedly mounted on the top of the rotating base 202, and a locking hole 205 is provided at the center of the top of the rotating rod 204 for use with the locking shaft 203. The locking shaft 203 is inserted into the locking hole 205 to limit and lock the rotating rod 204, ensuring the stability of the rotating rod 204 during operation.

[0024] Furthermore, a carrying rod 104 is fixedly mounted on the other side of the main body 101. The outer wall of the carrying rod 104 is covered with a rubber sleeve. The carrying rod 104 facilitates the worker to carry the repair tool, thereby increasing the portability of the repair tool. The rubber sleeve increases the flexibility of the outer wall of the carrying rod 104, improving the worker's comfort when holding the carrying rod 104 for a long time.

[0025] Furthermore, both sides of the top of the main disk body 101 are fixedly mounted with a snap ring 108 used in conjunction with the rotating rod 204. Among them, the snap ring 108 can be connected and locked to the rotating rod 204 when the tool is retracted, ensuring the stability of the staff when carrying the tool.

[0026] Furthermore, all three groups of hooks 301 are provided with anti-skid patterns 302. The anti-skid patterns 302 increase the friction of the hooks 301 and improve the stability of the hooks 301 when they are connected to the outer ring of the bearing.
