Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and particularly to a device for installing a motor drive gear. Background Art

[0002] Generally, during the motor assembly process, when installing the motor shaft and the drive gear, workers directly use tools to strike the motor to knock the drive gear into the motor shaft. This method of motor assembly not only has low assembly efficiency, is time-consuming and laborious, but also the quality of motor assembly completely depends on the proficiency of the workers. Moreover, the motor is prone to damage to the motor encoder due to axial force, resulting in a relatively high risk of motor damage. Summary of the Invention

[0031] As Figure 1 shown, Figure 1 is a schematic structural view of a motor transmission gear installation device in an embodiment.

[0032] In this embodiment, the motor drive gear mounting device is used to assemble the drive gear 2 to the motor shaft. The tooling includes a bottom plate 10, a fixed seat 30, a gear pushing device 20, and a motor 1 fixing device.

[0033] The fixed seat 30 is fixedly arranged on one side of the bottom plate 10 and is used to fix the gear pushing device 20.

[0034] One end of the gear pushing device 20 is arranged on the fixed seat 30, and the other end is used to connect to the motor shaft and abut against the drive gear 2, and is used to push the drive gear 2 in the direction close to the motor shaft. That is, under the action of an external force, through the gear pushing device 20, the force is transmitted to the drive gear 2, so that the drive gear 2 moves in the direction close to the motor shaft, and the drive gear 2 is installed at a preset position on the motor shaft.

[0035] The motor fixing device 40 is fixedly arranged on the other side of the bottom plate 10 and is used to fix the motor 1 to prevent the motor 1 from moving during the installation of the drive gear 2.

[0036] The above-mentioned motor drive gear mounting device includes a bottom plate 10, a fixed seat 30, a gear pushing device 20, and a motor fixing device 40. The motor 1 is fixed through the bottom plate 10 and the motor fixing device 40, and the force is transmitted to the drive gear 2 through the fixed seat 30 and the gear pushing device 20, and then the drive gear 2 is pushed into the motor shaft. It avoids directly using a tool to strike the motor 1 to knock the drive gear 2 into the motor shaft, thereby damaging the encoder of the motor 1 and reducing the risk of damage to the motor 1. In addition, when using this tooling for the assembly of the motor 1, compared with directly using a tool to strike the motor 1 by a worker, the installation of the drive gear 2 is simple and reliable, which can effectively improve the assembly efficiency and accuracy and avoid the situation of incomplete assembly caused by unskilled operation of the worker.

[0037] Please refer to Figures 2 to 5 , in one embodiment, the gear pushing device 20 includes a rocker 21, a pull rod 22, and a push block 23. The rocker 21 is threadedly connected to the fixed seat 30, and the left end face abuts against the first end face of the push block 23 and is used to push the push block 23 in the direction close to the motor shaft. One end of the pull rod 22 is fixedly connected to the fixed seat 30, and the other end is connected to the motor shaft. The push block 23 is sleeved on the pull rod 22, and the second end face abuts against the drive gear 2 and is used to push the drive gear 2 in the direction close to the motor shaft under the action of the rocker 21. The first end face and the second end face are oppositely arranged.

[0038] During the actual operation process, the rocker 21 is used to push the push block 23, and then push the drive gear 2 to move, so that the drive gear 2 is evenly stressed and installed at a preset position on the motor shaft.

[0039] In one embodiment, the pull rod 22 includes a connecting portion 221 and a guiding portion 220. The connecting portion 221 is threadedly connected to the motor shaft, and the guiding portion 220 is fixedly connected to the fixed seat 30. The push block 23 is a cylinder with a through hole in the middle that matches the guiding portion 220. The push block 23 is passed through the guiding portion 220 through the through hole and pushes the transmission gear 2 to move under the push of the rocker 21. In one embodiment, the connecting portion 221 is formed by a section of bar stock of the pull rod 22 through a turning tool.

[0040] In one embodiment, the motor fixing device 40 includes two fixing blocks 41. The two fixing blocks 41 are symmetrically arranged on both sides of the motor 1 and are used to lock the motor 1 to prevent the motor 1 from moving in the direction perpendicular to the motor shaft (i.e., moving left and right).

[0041] In one embodiment, the tooling further includes a limit plate 50. The limit plate 50 is movably arranged on the two fixing blocks 41 and is used to define a preset position of the transmission gear 2 in the axial direction of the motor, prevent the transmission gear 2 from approaching the motor 1 excessively, and ensure the clearance between the transmission gear 2 and the motor 1 when the transmission gear 2 is pushed and installed.

[0042] In one embodiment, a screw 43 is respectively installed on the two fixing blocks 41. One end of the limit plate 50 is movably connected to a fixing block 41 through a movable hole 53 and the screw 43. The other end of the limit plate 50 is provided with a clamping groove 51 that is clamped on the screw 43 on the other fixing block 41. The limit groove 52 on the limit plate 50 cooperates with the transmission gear 2 to prevent interference between the limit plate 50 and the transmission gear 2. The limit plate 50 is movably installed, which is very convenient to facilitate defining the fixed position and removing the limit plate 50 after installation is completed.

[0043] In one embodiment, the fixed seat 30 is provided with a fixing groove 31, and the pull rod 22 is fixedly connected to the fixing groove 31 to prevent the pull rod 22 from moving in the axial direction of the motor shaft.

[0044] In one embodiment, the tooling further includes a locking screw 60. A threaded hole 32 perpendicular to the fixing groove 31 is provided on the side of the fixed seat 30 away from the rocker 21. The locking screw 60 locks the pull rod 22 through the threaded hole 32 to fix the pull rod 22 and prevent the pull rod 22 from moving. In one of the embodiments, the fixed seat 30 is composed of two T-shaped fixing parts. The rocker 21 is threadedly connected to one side of a T-shaped fixing part, and the locking screw 60 is connected to the other side of the other T-shaped fixing part. The pull rod 22 is located between the two T-shaped fixing parts. According to actual needs, in other embodiments, the fixed seat 30 formed by the two T-shaped fixing parts can be integrally formed or assembled.

[0045] In one embodiment, the pull rod 22 is provided with a locking groove 222, and the locking screw 60 locks the pull rod 22 through the locking groove 222.

[0046] In one embodiment, the contact surface between the locking screw 60 and the locking groove 222 is a flat surface, which can be locked more conveniently and quickly.

[0047] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
