Description

Technical Field

[0001] The utility model relates to the technical field of shaft diameter sleeve inspection tools, and specifically relates to a shaft diameter sleeve inspection tool for a motor shaft. Background Technique

[0002] The shaft diameter sleeve of a motor shaft is a cylindrical bushing sleeved on the motor shaft, also known as a shaft sleeve. It plays an important role in machinery. Especially when it is necessary to fix the gear shaft to prevent it from deviating in direction due to vibration, the shaft diameter sleeve can help fix and maintain stability. The shaft diameter sleeve is widely used, especially in places with light loads and convenient disassembly and assembly; during the production and processing of the shaft diameter sleeve of the motor shaft, it is necessary to detect the size of the shaft diameter sleeve of the motor shaft to obtain the required shaft diameter sleeve of the motor shaft.

[0003] In the prior art, when detecting the shaft diameter sleeve of a motor shaft, the output end of a cylinder is used to drive a fixture to clamp the shaft diameter sleeve to form a fixation; however, since the above can only clamp and fix the outer side of the shaft diameter sleeve and lacks the fixation of the inner side of the shaft diameter sleeve, that is, lacks the secondary fixation of the shaft diameter sleeve, the fixation of the shaft diameter sleeve is not firm enough. If the shaft diameter sleeve falls off or moves during detection, it may cause a safety accident and harm the operator, and it is not convenient to operate and use. In view of this, we introduce a shaft diameter sleeve inspection tool for a motor shaft. Content of the Utility Model

[0007] The positioning groove is opened on the surface of the workbench, and the positioning groove is integrally formed with the workbench. The number of the positioning grooves is two groups;

[0008] The push rod is arranged inside the positioning box, and the push rod is connected to the output end of the cylinder, and the cylinder can control the movement of the push rod;

[0009] A positioning mechanism is arranged inside the workbench. The motor of the positioning mechanism drives a moving block and a fixing rod to move, so that the fixing rod fixes the shaft diameter sleeve of the motor shaft.

[0010] Preferably, the positioning mechanism includes a positioning cavity opened inside the workbench. The positioning cavity is integrally formed with the workbench. The motor is connected inside the positioning cavity and is bolted inside the positioning cavity. The output end of the motor is connected to a threaded rod.

The number of the moving blocks is two groups. The fixed rods are connected to the tops of the moving blocks. The fixed rods are slidably connected inside the positioning grooves. The arrangement of the positioning grooves can limit the movement of the fixed rods.

[0011] Preferably, a limiting block is connected to the bottom of the moving block. A limiting groove for slidably connecting the limiting block is opened inside the workbench. When the moving block moves, the limiting block at the bottom of the moving block will slide inside the limiting groove. Thus, the arrangement of the limiting groove can make the moving block always move in a horizontal state.

[0012] Preferably, one end of the push rod is connected to a positioning block. The positioning block is fixedly arranged with the push rod. The positioning block is slidably connected inside the positioning box. The arrangement of the positioning box can limit the movement of the positioning block. An arc-shaped block is arranged on one side of the positioning block. The arc-shaped block is welded to the positioning block. A buffer mechanism is arranged inside the arc-shaped block.

[0013] Preferably, the buffer mechanism includes a buffer spring connected to the inside of the arc-shaped block. One side of the buffer spring is connected to an arc-shaped plate. The arrangement of the buffer spring can buffer the movement of the arc-shaped plate. One side of the arc-shaped plate is connected to a damping limiting rod, and the buffer spring is sleeved on the surface of the damping limiting rod.

[0014] Preferably, a bearing is sleeved on one side of the threaded rod. The bearing is embedded in the inner side wall of the workbench. The arrangement of the bearing can make the rotation of the threaded rod more convenient.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model controls the movement of the push rod inside the positioning box through a cylinder, so that the push rod drives the positioning block and the arc-shaped block to move. The arc-shaped block drives the arc-shaped plate to move to one side of the shaft diameter sleeve, so that the two arc-shaped plates clamp and fix the shaft diameter sleeve;

[0016] The arc-shaped plate will continuously fix the outside of the shaft diameter sleeve. The arc-shaped plate will squeeze the buffer spring inside the arc-shaped block, so that the buffer spring buffers the arc-shaped plate. It can avoid that when the cylinder fails, the shaft diameter sleeve can be protected by the arrangement of the buffer spring to prevent the shaft diameter sleeve from being damaged;

[0017] The output end of the motor drives the threaded rod to rotate. Since the thread directions of the threaded rods are arranged in opposite directions, the moving blocks can be controlled to move respectively and move to opposite positions. The fixed rod is controlled by the moving block to move inside the positioning groove, so that the fixed rod supports the inner side of the shaft diameter sleeve, thereby forming a second fixation, making the fixation more firm and facilitating the subsequent detection of the shaft diameter sleeve.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a shaft diameter sleeve inspection tool for a motor shaft, including: a workbench 1, positioning boxes 2 are arranged on both sides of the surface of the workbench 1, and a cylinder 3 is arranged on one side of the positioning box 2;

[0024] Positioning grooves 4, the positioning grooves 4 are opened on the surface of the workbench 1, and the number of the positioning grooves 4 is two groups;

[0025] Push rods 10, the push rods 10 are arranged inside the positioning box 2, and the push rods 10 are connected to the output end of the cylinder 3;

[0026] A positioning mechanism is arranged inside the workbench 1. The motor 11 of the positioning mechanism drives the moving block 15 and the fixed rod 5 to move, so that the fixed rod 5 fixes the shaft diameter sleeve of the motor shaft.

[0027] The positioning mechanism includes a positioning cavity 16 formed inside the workbench 1. The positioning cavity 16 and the workbench 1 are integrally formed. The motor 11 is connected inside the positioning cavity 16. The motor 11 is bolted inside the positioning cavity 16. The output end of the motor 11 is connected to a threaded rod 14. The thread directions of the threaded rod 14 are opposite with respect to the midpoint of the threaded rod 14. The moving block 15 is screwed onto the surface of the threaded rod 14. The number of the moving blocks 15 is two. The fixed rod 5 is connected to the top of the moving block 15. The fixed rod 5 is slidably connected inside the positioning groove 4. The setting of the positioning groove 4 can limit the movement of the fixed rod 5.

[0028] The bottom of the moving block 15 is connected with a limiting block 13. A limiting groove 12 for slidably connecting the limiting block 13 is formed inside the workbench 1. When the moving block 15 moves, the limiting block 13 at the bottom of the moving block 15 will slide inside the limiting groove 12. Thus, the setting of the limiting groove 12 can make the moving block 15 move always in a horizontal state.

[0029] One end of the push rod 10 is connected with a positioning block 7. The positioning block 7 and the push rod 10 are fixedly arranged. The positioning block 7 is slidably connected inside the positioning box 2. The setting of the positioning box 2 can limit the movement of the positioning block 7. One side of the positioning block 7 is provided with an arc-shaped block 6. The arc-shaped block 6 and the positioning block 7 are welded. A buffer mechanism is arranged inside the arc-shaped block 6.

[0030] The buffer mechanism includes a buffer spring 9 connected to the inside of the arc-shaped block 6. One side of the buffer spring 9 is connected with an arc-shaped plate 8. The setting of the buffer spring 9 can buffer the movement of the arc-shaped plate 8. One side of the arc-shaped plate 8 is connected with a damping limiting rod 17, and the buffer spring 9 is sleeved on the surface of the damping limiting rod 17.

[0031] A bearing is sleeved on one side of the threaded rod 14. The bearing is embedded in the inner side wall of the workbench 1. The setting of the bearing can make the rotation of the threaded rod 14 more convenient.

[0032] Specifically, during use, the shaft diameter sleeve for the motor shaft to be detected is installed on the top of the workbench 1, and the fixed rod 5 is inserted into the inner part of the shaft diameter sleeve. At this time, the air cylinder 3 is jointly controlled to start, so that the push rod 10 moves inside the positioning box 2, thereby driving the positioning block 7 and the arc-shaped block 6 to move by the push rod 10, and driving the arc-shaped plate 8 to move to one side of the shaft diameter sleeve by the arc-shaped block 6, so that the two arc-shaped plates 8 clamp and fix the shaft diameter sleeve. At this time, when the air cylinder 3 continues to work, the arc-shaped plate 8 will continuously fix the outer side of the shaft diameter sleeve, and the arc-shaped plate 8 will squeeze the buffer spring 9 inside the arc-shaped block 6, so that the buffer spring 9 buffers the arc-shaped plate 8, and the damping limit rod 17 on the surface of the buffer spring 9 will move inside the arc-shaped plate 8 to prevent the buffer spring 9 from shaking, which can make the arc-shaped plate 8 always move in a horizontal state. In case of a failure of the air cylinder 3, the buffer spring 9 can protect the shaft diameter sleeve and prevent the shaft diameter sleeve from being damaged;

[0033] At the same time, the two positioning boxes 2 and the air cylinders 3 have the same size, so that the air cylinders 3 can be jointly controlled to drive the arc-shaped plates 8 and the arc-shaped blocks 6 to have the same telescopic distance, avoiding damage to the clamped shaft diameter sleeve due to inconsistency;

[0034] The motor 11 is controlled to work, so that the output end of the motor 11 drives the threaded rod 14 to rotate. Since the thread directions of the threaded rod 14 are arranged in opposite directions, the moving blocks 15 can be respectively controlled to move, so as to move to opposite positions. Thus, the fixed rod 5 is controlled by the moving blocks 15 to move inside the positioning groove 4, and the fixed rod 5 props up the inner side of the shaft diameter sleeve, thereby forming a second fixation, which is more firm and convenient for subsequent detection of the shaft diameter sleeve and more convenient to use.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
