Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, in particular to a motor gap adjustment tool. Background Art

[0002] Motor clearance refers to the physical distance between moving parts within a motor (such as the stator and rotor, bearings and shafts, and gears), typically measured in millimeters (mm) or microns (μm). These clearances are intentionally retained in motor design to ensure proper operation, reduce friction, dissipate heat, and compensate for manufacturing errors. During motor production, precise adjustment of motor clearances has a crucial impact on key indicators such as motor performance, noise, vibration, and service life. Traditional motor clearance adjustment methods often rely on manual experience, resulting in low adjustment accuracy, poor efficiency, and difficulty ensuring consistency. To address these issues, the design of a dedicated motor clearance adjustment tool is particularly necessary.

[0003] In the prior art, when inspecting and adjusting the axial clearance of a motor, a clamp is usually used to limit the motor first. The motor housing on one side is abutted against the probe of a dial indicator. Using an instrument connected to the other side of the motor, the motor is pulled or pushed, causing the motor housing to deform. The deformation displacement is converted into a dial indicator reading, thereby obtaining the motor clearance value. During the process of limiting the motor, a clamp is required to clamp the motor in the middle and fix it. However, the clamping force cannot be too large. The motor housing (especially aluminum alloy) undergoes slight elastic or plastic deformation under excessive pressure. After deformation, the actual position of the motor shaft may shift, resulting in inaccurate gap value measurement. Many operators cannot control the abutment force between the clamp and the motor, resulting in excessive squeezing between the clamp and the motor housing, thereby affecting the accuracy of the measurement data.

The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0024] The following combination Figures 1-13 The motor gap adjustment tool of the present invention is described.

[0025] like Figure 1-Figure 5 As shown, in one embodiment, the motor gap adjustment tooling includes a base plate 1 and positioning holes 101 opened at both ends of the base plate 1, and also includes: a positioning plate 2, which is screwed and set on the positioning hole 101; a positioning frame 3, which is fixedly installed on the base plate 1; a screw rod 4, which is rotatably set on the positioning frame 3; a movable frame 5, which is movably sleeved on the outside of the screw rod 4, and a connecting tool is detachably installed on one side, and is connected to one side of the motor; a dial indicator 6, which is installed on the other side of the base plate 1, wherein the probe is in contact with the outer casing of the other end of the motor; a fixed frame 7, which is axially symmetrically arranged on both sides of the base plate 1; a moving rod 9, which movably passes through one side of the fixed frame 7; a pressure plate 10, which is fixedly installed on one end of the moving rod 9 and movably abuts against the motor casing; a moving block 11, which is slidably installed inside the fixed frame 7; a buffer assembly 8, which is provided on the moving block 11 to prevent the pressure plate 10 from excessively squeezing the motor.

[0026] Specifically, positioning holes 101 are provided at both ends of the bottom plate 1. The positioning holes 101 on one side are screwed with the positioning plate 2 to fix the positioning plate 2 on the bottom plate 1. The number of positioning holes 101 on the other side is set to multiple. The fixing position of the positioning plate 2 can be adjusted according to the size of the motor, and can be adapted to motors of different sizes. The two positioning plates 2 fix the motor in the middle, which can preliminarily limit and fix the motor. The fixing frames 7 are set at both ends of the motor. The moving rod 9 is moved along the fixing frame 7 in the direction close to the motor. The movement of the moving rod 9 will drive the pressure plate 10 to move toward the direction of the motor until it abuts against the motor housing. The buffer component 8 can prevent the pressure plate 10 from abutting too tightly against the motor housing, which will cause the motor to The deformation of the shell affects the subsequent measurement results of the gap value. The moving block 11 provides space for the buffer assembly 8. After the pressure plate 10 abuts and limits the motor, there are materials on all four sides of the motor for positioning, which can ensure the stability of the motor. After the motor is fixed, the probe of the dial indicator 6 is abutted against the motor shell, and a connecting tool is installed on one side of the moving frame 5, which is connected to the other end of the motor shell. Then the screw rod 4 is rotated. The rotation of the screw rod 4 will drive the moving frame 5 to move, pulling or pushing the motor. The motor shell will produce a certain deformation, and the probe of the dial indicator 6 will convert the deformation into a reading on the dial indicator 6, thereby calculating the gap value of the motor. The positioning frame 3 provides support for the screw rod 4.

[0027] See Figure 4-Figure 7 As shown, in this embodiment, the buffer assembly 8 includes a movable frame 81, and movable grooves 82 are axially symmetrically opened on both sides of the movable block 11. The movable frame 81 is slidingly connected to the movable groove 82. One end of the movable frame 81 is fixedly connected to the end of the movable rod 9 away from the pressure plate 10. A sliding frame 83 is movably provided on the other side of the movable groove 82. The sliding frame 83 is fixedly connected to the movable frame 81 by a reset spring 84.

[0028] Specifically, the motor is placed between the two fixed frames 7, and the pressure plate 10 is still a certain length away from the motor housing. Then the moving block 11, the movable frame 81, and the sliding frame 83 are moved together in the direction close to the motor, and the moving rod 9 and the pressure plate 10 also move with the movable frame 81. The pressure plate 10 will first abut against the motor housing. At this time, the moving direction of the moving block 11 remains unchanged. Due to the limiting effect of the motor housing, the pressure plate 10 and the moving rod 9 will move in the direction close to the fixed frame 7. The fixed frame 7 always remains stationary. The movement of the moving rod 9 will drive the movable frame 81 to move in the opposite direction along the movable groove 82, thereby compressing the reset spring 84. This can prevent the pressure plate 10 from excessively squeezing the motor housing.

[0029] See Figure 5-Figure 8As shown, in this embodiment, a vertical rod 12 is provided for rotation at the center of the movable block 11, and a driving gear 13 is fixedly sleeved on the top of the vertical rod 12. A rack 14 is provided on one end of the movable frame 81 and the sliding frame 83 close to each other. The two racks 14 are engaged with the driving gear 13 on the left and right for transmission. A fixed cylinder 15 is fixedly provided on one side of the movable frame 81, and a movable rod 16 is fixedly provided on the sliding frame 83. The movable rod 16 is slidably connected to the fixed cylinder 15.

[0030] Specifically, the pressure plate 10 moves in the opposite direction after being limited by the motor housing, and the pressure plate 10 will drive the moving rod 9 and the movable frame 81 to move in the opposite direction. The movable frame 81 moves in the opposite direction relative to the moving block 11, which will drive the rack 14 on the same side to move. The movement of the rack 14 drives the driving gear 13 to rotate, thereby driving the rack 14 on the other side to move. The moving direction of the rack 14 and the sliding frame 83 on the other side is the same as the moving direction of the moving block 11, that is, the movable frame 81 and the moving frame 5 approach each other, and the movable rod 16 moves along the inside of the fixed cylinder 15. During this process, the return spring 84 will be compressed. The return spring 84 plays a buffering role to prevent the pressure plate 10 from excessively squeezing the motor housing, and the vertical rod 12 provides support for the driving gear 13.

[0031] See Figure 6 and Figures 9-11 As shown, in this embodiment, the movable frame 81 is located on one side of the fixed cylinder 15 and is fixedly provided with a positioning frame 17, and the sliding frame 83 is located on one end of the movable rod 16 and is fixedly provided with a positioning block 18. The positioning block 18 is slidably connected to the positioning frame 17, and a slot 171 is provided on one side of the positioning frame 17. A limiting hole 172 is provided on the inner wall of the slot 171 of the positioning frame 17, and a limiting ball 19 is provided on one side of the positioning block 18, and the limiting ball 19 is movably engaged with the limiting hole 172.

[0032] Specifically, due to the limiting effect of the motor housing, the movable frame 81 and the sliding frame 83 approach each other, and the positioning block 18 will move toward the inside of the positioning frame 17. In the initial state, the part of the positioning block 18 where the limiting ball 19 is set is located in the positioning frame 17. The limiting ball 19 is made of elastic material and is squeezed by the inner wall of the positioning frame 17. The limiting ball 19 is in a compressed state. The positioning block 18 drives the limiting ball 19 to move along the inside of the positioning frame 17. When the positioning block 18 drives the limiting ball 19 to move to a position flush with the limiting hole 172, the limiting ball 19 is engaged with the limiting hole 172. At this time, the positioning block 18 cannot move relative to the positioning frame 17, and relative movement between the movable frame 81 and the sliding frame 83 can no longer occur.

[0033] See Figures 9-11As shown, in this embodiment, a circular ring 20 is fixedly provided in the limiting hole 172 , and a push rod 21 is movably provided through the center of the circular ring 20 , one end of the push rod 21 is movably abutted against the limiting ball 19 , and the push rod 21 and the circular ring 20 are connected by a positioning spring 22 .

[0034] Specifically, when it is necessary to release the engagement between the limiting ball 19 and the limiting hole 172, the push rod 21 is moved into the limiting hole 172. The inward movement of the push rod 21 will push the limiting ball 19 in the limiting hole 172 to move so that it is no longer engaged with the limiting hole 172. At this time, the movable frame 81 and the sliding frame 83 can move. During this process, the positioning spring 22 will be compressed, and the ring 20 provides support for the positioning spring 22. When the limiting ball 19 is released from the limiting hole 172, the inward force applied to the push rod 21 is removed, and the positioning spring 22 will drive the push rod 21 back to its initial position.

[0035] See Figure 7-Figure 9 As shown, in this embodiment, a movable plate 23 is movably provided in the slot 171, and one end of the movable plate 23 movably passes through the fixed frame 7. The movable plate 23 is located inside the slot 171 and is separately provided with an inclined groove 231. The inclined groove 231 is movably abutted against the end of the push rod 21 away from the limiting ball 19. A push plate 24 is fixedly provided on the inner wall of the movable slot 82, and the push plate 24 is movably abutted against one side of the sliding frame 83.

[0036] Specifically, after the limiting ball 19 is engaged with the limiting hole 172, the movable plate 23 is moved inward along the slot 171. The inward movement of the movable plate 23 will drive the inclined groove 231 to abut against the top rod 21. Under the limiting action of the inclined groove 231, the top rod 21 will be pushed to move toward the inside of the limiting hole 172 so that the limiting ball 19 at the other end is no longer engaged with the limiting hole 172. The other end of the movable plate 23 can be elastically connected to the inner wall of the slot 171, which can facilitate the movable plate 23 to move back to the initial position.

[0037] See Figure 7 and Figure 8 As shown, in this embodiment, the movable block 11 is located on the inner wall of one of the movable grooves 82 and is provided with a groove 111. A stopper 25 is movably provided in the groove 111. The stopper 25 is connected to the inner wall of the groove 111 by a limit spring 26. A notch 251 is axially symmetrically provided on the other side of the stopper 25. The stopper 25 is movably abutted against the movable frame 81.

[0038] Specifically, in the initial state, the moving block 11, the movable frame 81, and the sliding frame 83 move together in the direction close to the motor, and the notch 251 of the stopper 25 is also located outside the groove 111. The push plate 24 is also in contact with one side of the sliding frame 83. The movement of the movable frame 5 will drive the push plate 24 to move, thereby driving the sliding frame 83 to move synchronously. The movable frame 81 is also moved synchronously by the contact effect of the stopper 25. When the pressure plate 10 abuts against the motor housing, the pressure plate 10, the moving rod 9 and the movable frame 81 move in the opposite direction. The cooperation of the driving gear 13 and the rack 14 will realize that the movable frame 81 and the sliding frame 83 are close to each other. The movable frame 81 moves along the movable groove 82 and abuts against the notch 251 opened in the stopper 25, thereby pushing the stopper 25 to move inside the groove 111, thereby compressing the limit spring 26, and the sliding frame 83 will move in the opposite direction to the movable frame 81. During this process, the positioning block 18 will The positioning frame 17 moves inside until the limiting ball 19 engages with the limiting hole 172. At this time, the movable frame 81 and the sliding frame 83 remain in a relatively stationary state, and the pressure plate 10 also remains stationary and abuts against the motor housing, but the moving block 11 is still in a moving state. Until the push plate 24 abuts against the sliding frame 83 again, the moving block 11 is also in a state that cannot move. This can prevent the pressure plate 10 from excessively squeezing the motor. The movement of the moving block 11 drives the pressure plate 10 to move and abut against the motor housing, so that the pressure plate 10 can limit and fix motors of different sizes, because the pressure plate 10 will only move in the opposite direction after abutting against the motor housing, and the distance of reverse movement is also fixed (because the engaging position of the limiting ball 19 and the limiting hole 172 is fixed). The distance of synchronous movement of the moving block 11 and the pressure plate 10 corresponds to motors of different sizes. The larger the motor size, the shorter the synchronous movement distance of the two, and the smaller the motor size, the longer the synchronous movement distance of the two.

[0039] See Figure 4 and Figure 5 As shown, in this embodiment, a rotating cylinder 27 is movably provided in the moving block 11 , the rotating cylinder 27 is threadedly connected to the moving block 11 , and the other end of the rotating cylinder 27 movably passes through the fixed frame 7 .

[0040] Specifically, the rotation of the rotating cylinder 27 can drive the moving block 11 to move in the fixed frame 7. Since the rotating cylinder 27 is threadedly connected to the moving block 11, the moving block 11 can be easily moved.

[0041] See Figure 2 and Figure 12-13 As shown, in this embodiment, a serrated ring 28 is provided inside the rotating cylinder 27 located outside the fixed frame 7 , a serrated plate 29 is movably engaged inside the serrated ring 28 , and a fixing ring 30 is fixedly sleeved outside the serrated plate 29 .

[0042] Specifically, when the serrated plate 29 is engaged with the serrated ring 28 , the rotating fixing ring 30 drives the serrated plate 29 to rotate, thereby driving the serrated ring 28 and the rotating cylinder 27 to rotate, thereby achieving lateral movement of the moving block 11 .

[0043] See Figure 12-13 As shown, in this embodiment, a rotating ring 31 is movably sleeved on the outer side of the rotating cylinder 27, and axially symmetrical clamping grooves 311 are opened on both sides of the rotating ring 31. Clamping blocks 32 are fixedly provided on both sides of the fixed ring 30, and the clamping blocks 32 are movably connected to the clamping grooves 311.

[0044] Specifically, when the serrated plate 29 is engaged with the serrated ring 28, the rotation of the rotating ring 31 drives the block 32 and the fixed ring 30 to move synchronously through the action of the slot 311. The rotation of the fixed ring 30 will drive the serrated plate 29 to rotate, thereby driving the serrated ring 28 and the rotating cylinder 27 to rotate. When the pressure plate 10 is in contact with the motor housing and there is no need to move the moving block 11, the block 32 is moved outward along the slot 311. The block 32 drives the fixed ring 30 and the serrated plate 29 to move outward, and the serrated plate 29 is no longer engaged with the serrated ring 28. At this time, the rotation of the rotating ring 31 will not drive the rotating cylinder 27 to rotate, thereby avoiding the movement of the moving block 11 caused by the accidental rotation of the rotating ring 31.
