Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to an installation tool for ensuring the concentricity between a motor base and an input shaft. Background Technique

[0002] In the prior art, when a motor is connected to an input shaft, a motor base is used to support and fix the motor. In the prior art, the installation method of the motor base is usually to directly install it by aligning the installation holes. This direct installation method often causes an offset between the motor base and the input shaft, and the concentricity cannot be achieved. As a result, the connection between the motor drive shaft and the input shaft is offset. If the connection between the motor drive shaft and the input shaft is not concentric, it will affect the subsequent drive.

[0019] Referring to Figures 1 - 3 , an installation tooling for ensuring the concentricity of the motor base and the input shaft includes an installation tooling body 1 that cooperates with the motor base 3 and the input shaft 4. A motor 5 is cooperatively arranged on the right side of the input shaft 4. The installation tooling body 1 includes a positioning shaft 101, and a circular positioning plate 102 is fixedly sleeved on the positioning shaft 101. A plurality of weight reduction holes 1022 are annularly formed on the right side of the circular positioning plate 102.

The right end of the positioning shaft 101 is fixedly connected to a handle 103 located on the right side of the circular positioning plate 102. The entire installation tooling body 1 can be pulled through the handle 103. The outer circle of the circular positioning plate 102 is a positioning outer circle 1021, the left side of the circular positioning plate 102 is set as a positioning end face 1023, and a first positioning square inner groove 104 is formed at the center of the left end of the positioning shaft 101. The first positioning square inner groove 104 is coaxial with the circular positioning plate 102;

[0020] On the outer right side of the motor base 3, a first circular protrusion 304 is integrally provided. On the outer left side of the motor base 3, a second circular protrusion 305 is integrally provided. The left side of the second circular protrusion 305 is in movable contact with the mounting seat 2. A plurality of first mounting holes 201 are annularly formed on the right side of the mounting seat 2. A plurality of second mounting holes 302 are annularly formed on the left side of the second circular protrusion 305.

The motor base 3 can be fixed to the right side of the mounting seat 2 by means of the first mounting holes 201, the second mounting holes 302 and an external bolt. The mounting seat 2 is sleeved on the input shaft 4. The right end of the input shaft 4 extends into the motor base 3. An annular groove 301 with an open right side is formed on the inner right side of the motor base 3. The circular positioning plate 102 is movably sleeved in the annular groove 301. The left inner wall of the annular groove 301 is in movable contact with the left side of the positioning end face 1023. The positioning shaft 101 is located in the motor base 3. The positioning outer circle 1021 is in movable contact with the inner wall of the annular groove 301, so as to ensure that the positioning shaft 101 is located at the central axis of the motor base 3. The right end of the input shaft 4 is movably sleeved in the first positioning square inner groove 104;

[0021] On the outer left side of the motor 5, a motor positioning stop 501 is provided. The inner diameter of the motor positioning stop 501 is the same as the inner diameter of the annular groove 301 and the outer diameter of the positioning outer circle 1021. Setting the sizes to be the same can ensure that the motor 5 will not be offset during installation. Among them, a plurality of first motor bolt holes 303 are annularly formed on the right side of the first circular protrusion 304. An outer edge is integrally provided on the outer side of the motor 5. A plurality of second motor bolt holes are formed on the right side of the outer edge. The first motor bolt holes 303 cooperate with the corresponding second motor bolt holes. The first motor bolt holes 303, the second motor bolt holes and an external bolt cooperate to fix the motor 5. A drive shaft 503 is provided on the left side of the motor 5. A coupling 502 is fixedly sleeved on the drive shaft 503. A second positioning square inner groove 504 is formed on the left side of the coupling 502. The second positioning square inner groove 504 is adapted to the right end of the input shaft 4. The inner diameter of the second positioning square inner groove 504 is the same as the inner diameter of the first positioning square inner groove 104. The connection between the drive shaft 503 and the input shaft 4 is realized through the coupling 502; Through the setting of the installation tooling body 1 of the present utility model, the motor base 3 can be effectively positioned during the installation of the motor base 3, ensuring the concentricity between the motor base 3 and the input shaft 4, effectively avoiding the situation of offset installation of the motor base 3, improving the installation accuracy. In addition, after positioning and installing the motor base 3, the motor 5 and the input shaft 4 are connected through the coupling 502, which can ensure the coaxial state of the motor 5 and the input shaft 4.

[0022] Working principle: When installing the motor base 3, first, the installation tooling body 1 is sleeved inside the motor base 3. The circular positioning plate 102 on the installation tooling body 1 is movably sleeved inside the annular groove 301. Since the positioning outer circle 1021 is in movable contact with the inner wall of the annular groove 301, and the first positioning square inner groove 104 is coaxial with the circular positioning plate 102, the concentricity between the positioning shaft 101 and the motor base 3 can be determined. After the installation tooling body 1 and the motor base 3 are assembled, move the motor base 3 and the installation tooling body 1 to the left. The motor base 3 moves to the left until it is in movable contact with the right side of the mounting base 2. While the installation tooling body 1 moves to the left, the first positioning square inner groove 104 on it is sleeved on the input shaft 4. After sleeving, the coaxiality between the motor base 3 and the input shaft 4 can be determined at this time. Immediately afterwards, the motor base 3 can be fixed to the right side of the mounting base 2 through the cooperation of the first mounting hole 201 and the second mounting hole 302 with external bolts. At this time, the motor base 3 and the input shaft 4 are in a coaxial state. Immediately afterwards, the grip 103 can be pulled to the right to remove the installation tooling body 1 from the motor base 3, and the installation tooling body 1 is separated from the input shaft 4. By positioning the motor base 3 with the installation tooling body 1 and then fixing the motor base 3, the situation of the motor base 3 being installed offset can be effectively avoided, ensuring the concentricity between the motor base 3 and the input shaft 4 and improving the installation accuracy;

[0023] Immediately afterwards, the motor positioning stop 501 on the motor 5 can be sleeved inside the annular groove 301. The motor 5 drives the coupling 502 to move to the left into the motor base 3 through the drive shaft 503. The coupling 502 drives the second positioning square inner groove 504 on it to be sleeved on the input shaft 4. Since the inner diameter of the motor positioning stop 501 is the same as the inner diameter of the annular groove 301 and the outer diameter of the positioning outer circle 1021, the situation of the motor 5 being installed offset can be effectively avoided. After alignment, the motor 5 can be fixed through the cooperation of the first motor bolt hole 303, the second motor bolt hole and external bolts. At this time, the input shaft 4 and the motor 5 are connected through the coupling 502, which can ensure the coaxial state between the motor 5 and the input shaft 4. By positioning and installing the motor base 3 and then installing the motor 5, the situation that the drive shaft 503 of the input shaft 4 and the motor 5 are not concentric can be effectively avoided.
