Description

Technical Field

[0001] The utility model belongs to the field of motor disassembly tools, and in particular relates to a motor bearing disassembly device. Background Art

[0002] Bearings are components that fix and reduce load friction coefficients in the process of mechanical transmission. They are an important component in modern mechanical equipment. They are installed on the shaft or sleeve by the inner edge or outer edge as needed. When the motor bearing needs to be repaired or maintained after a long period of use, the bearing must be removed from the motor shaft first.

[0003] In the prior art, manual methods are often used to disassemble bearings. When the gap between the motor bearing and the motor rotor is small, it is not conducive to manual disassembly, and the bearing is often difficult to remove. Sometimes a hammer is used directly to knock for disassembly, which can easily cause damage to the bearing and increase the consumption of accessories. The existing motor bearing disassembly tool is a three-claw tool. Due to the small gap between the motor bearing and the motor rotor, the three-claw tool is difficult to exert force and cannot remove the motor bearing from the motor shaft. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a motor bearing disassembly device. When the gap between the motor bearing and the motor rotor is small, the disassembly is very convenient, the operation is simple, and it saves time and effort.

[0023] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0024] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] Example 1

[0026] like Figure 1 As shown, this embodiment provides a motor bearing disassembly device, including a first locking block 1, a second locking block 2, and a pressure rod 6.

[0027] like Figure 2 As shown, a first through slot 8 is provided on one side of the first locking block 1. The first through slot 8 passes through the first locking block 1 vertically, and the bottom end of the first through slot 8 expands outward to form a first clamping slot 7;

[0028] A second through slot 10 is disposed on one side of the second locking block 2 . The second through slot 10 passes through the second locking block 2 from top to bottom, and a bottom end of the second through slot 10 expands outward to form a second clamping slot 9 .

[0029] Screw holes are penetrated on the side walls of the first locking block 1 and the second locking block 2. The first locking block 1 and the second locking block 2 are locked and fixed by bolts 4, and the bolts 4 are screwed into the screw holes of the two locking blocks.

[0030] After the first locking block 1 and the second locking block 2 are locked and fixed, the first clamping groove 7 and the second clamping groove 9 together form a clamping groove, which is clamped on the outside of the motor bearing 3, and the clamping groove and the motor bearing 3 are interference fit, so that the motor bearing 3 and the clamping groove remain relatively fixed. Figure 3 As shown, the first through slot 8 and the second through slot 10 together form a through hole, at which time the top end of the motor shaft 5 is located in the through hole, and the bottom end of the pressure rod 6 is inserted into the through hole and abuts against the top end of the motor shaft 5 .

[0031] Wherein, friction lines may be provided on the inner side walls of the first clamping groove 7 and the second clamping groove 9 to increase the friction between the clamping groove and the motor bearing 3, thereby improving stability.

[0032] Based on the above structure, when manually disassembling the bearing, the motor shaft 5 is arranged upward, and then the first locking block 1 and the second locking block 2 are placed above the motor, so that the first clamping groove 7 and the second clamping groove 9 are covered on the outside of the motor bearing 3, and then the bolt 4 is tightened to lock and fix the first locking block 1 and the second locking block 2. At this time, the clamping groove and the motor bearing 3 are interference fit and remain relatively fixed. Then, the pressure rod 6 can be pressed downward manually, and the pressure rod 6 generates downward pressure on the motor shaft 5. At this time, the first locking block 1 and the second locking block 2 remain stationary, that is, the motor bearing 3 remains stationary until the motor shaft 5 is separated from the motor bearing 3, and the motor bearing can be disassembled. When the gap between the motor bearing 3 and the motor rotor is small, the device is also very convenient to disassemble, simple to operate, and saves time and effort.

[0033] In this embodiment, a pressing column 14 is coaxially fixed to the other end of the pressing rod 6. The pressing column 14 is directly larger than the through hole. The setting of the pressing column 14 is convenient for the staff to press manually, and can also prevent the pressing rod 6 from moving down too much, avoiding the situation where excessive force causes damage to the device.

[0034] Please refer again Figure 2 Two first wire passing grooves 11 are provided on one side of the first locking block 1, and two second wire passing grooves 12 are provided on one side of the second locking block 2. After the first locking block 1 and the second locking block 2 are locked and fixed, the first wire passing groove 11 and the second wire passing groove 12 together constitute a wire passing hole, and the wire passing hole is used for the wire harness 13 to pass through, which can avoid damage to the wire harness.

[0035] Please refer again Figure 1 A clearance groove 15 is provided on the side wall of the first locking block 1, and the bolt head of the bolt 4 is embedded in the clearance groove 15, which can ensure the planarity of the side wall of the first locking block 1.

[0036] Example 2

[0037] like Figure 4-5 As shown, on the basis of Example 1, it also includes a positioning mechanism, which includes a positioning plate 16 and a support frame 17. The positioning plate 16 is installed on the support frame 17. The positioning plate 16 is provided with a receiving hole 20 running through the upper and lower parts. A lap plate 18 is fixed on the inner wall of the accommodating hole 20. The accommodating hole 20 is adapted to the first locking block 1 and the second locking block 2. The first locking block 1 and the second locking block 2 are both overlapped on the lap plate 18 so that the motor is placed below the accommodating hole 20.

[0038] The positioning mechanism further includes a receiving plate 19 , which is fixed on the supporting frame 17 and is located below the receiving hole 20 .

[0039] After the first locking block 1 and the second locking block 2 are locked and fixed, the clamping groove is tightly fitted with the motor bearing 3, and then the motor is placed in the accommodating hole 20, so that the first locking block 1 and the second locking block 2 are overlapped on the overlapping plate 18. At this time, pressing down the pressure rod 6 can disengage the motor shaft 5 from the motor bearing 3, and the positioning plate 16 can ensure the stability of the first locking block 1 and the second locking block 2 to avoid deviation during the pressing process.

[0040] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
