Description

Technical Field

[0001] This utility model relates to the field of test bench motor installation technology, and in particular to a vertical test bench motor disassembly and assembly tool. Background Technology

[0002] The structure of a vertical test bench 10 is as follows: Figure 1 As shown, a base plate 11 is welded to the bottom of the vertical test bench 10. A motor mounting plate 12 is welded to the vertical test bench 10 above the base plate 11. The mounting plate 12 has a shaft hole 121 in the center and motor mounting holes 122 around the shaft hole 121. The shaft hole 121 is for the output shaft of the motor to pass through, and the motor mounting holes 122 are for the flange of the motor 30 to be bolted to the mounting plate 12. The motor 30 is mounted on the lower side of the motor mounting plate 12. In use, the output shaft of the motor 30 extends upward and connects to the upper drive shaft for transmission.

[0003] When installing or disassembling the motor 30, the motor is heavy and the installation space under the vertical test bench 10 is relatively narrow. It is time-consuming and laborious to install or disassemble it manually. Therefore, in order to facilitate the installation or disassembly of the motor 30, a vertical test bench motor disassembly and assembly tooling of this application is designed. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical test bench motor assembly and disassembly fixture, which facilitates the installation or disassembly of the motor.

[0005] To achieve the above objectives, this utility model provides a vertical test bench motor assembly and disassembly fixture, including an auxiliary device. The auxiliary device includes a base, guide rods, a lifting plate, and a drive screw. Four guide rods are vertically and fixedly installed on the upper side of the base. The four guide rods are arranged in pairs, and a lifting plate is slidably installed on each pair of guide rods. The motor mounting plate on the vertical test bench is provided with through holes at the positions corresponding to the lifting plates. The threaded end of the drive screw moves through the through holes and then screws into the lifting plate.

[0006] The base is slidably connected to the bottom plate on the vertical test bench via a sliding structure.

[0007] The sliding structure includes linear guide rails and sliders. Two linear guide rails are installed on the base plate at intervals and parallel to each other. At least one slider is slidably installed on the linear guide rails. One end of the base is fixedly installed on the slider, and the other end of the base is cantilevered. The guide rod is installed on the cantilevered end of the base.

[0008] The linear guide rail is fixedly installed with stops at both ends.

[0009] The lifting plate includes a connecting part and a protruding part. The two ends of the connecting part are respectively provided with sliding holes. The protruding part is located in the middle of the connecting part and extends to one side. The protruding part is provided with a threaded hole. The two sliding holes are respectively slidably connected to the guide rods of each group. The drive screw is screwed into the threaded hole.

[0010] The drive screw includes a screw body, a limiting rod, and a handle. The screw body is fixed to one end of the limiting rod, and the handle is installed at the other end of the limiting rod. The diameter of the limiting rod is larger than the diameter of the screw body, thereby forming a step at the end where the limiting rod is connected to the screw body.

[0011] The base is also equipped with a positioning device.

[0012] The positioning device is a limiting ring.

[0013] The inner hole of the limiting ring is a tapered hole that is larger at the top and smaller at the bottom.

[0014] Compared with the prior art, this utility model has the following technical effects:

[0015] 1. The guide rod of this utility model is used to guide the sliding of the lifting plate. The lifting plate is used to abut against the flange of the motor. By synchronously rotating the drive screw, the lifting plate is driven to rise. Since the lifting plate abuts against the lower side of the motor flange, the two lifting plates drive the motor to rise, thus facilitating the installation of the motor. When disassembling the motor, it can also make the motor descend smoothly, facilitating the disassembly of the motor.

[0016] 2. The base of this utility model is slidably connected to the base plate on the vertical test bench through a sliding structure. The base can slide directionally on the base plate, which facilitates the movement of the motor into the vertical test bench.

[0017] 3. The base of this utility model is also equipped with a positioning device, which facilitates the positioning of the motor, so that when the slider abuts against the left side stop, the motor output shaft is aligned with the shaft hole on the motor mounting plate.

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0032] Example 1:

[0033] Please see Figure 1-7 A vertical test bench motor assembly and disassembly fixture includes an auxiliary device 20. The auxiliary device 20 includes a base 21, guide rods 22, lifting plates 23, and a drive screw 24. Four guide rods 22 are vertically and fixedly installed on the upper side of the base 21. The four guide rods 22 are arranged in pairs. A lifting plate 23 is slidably installed on each pair of guide rods 22. The motor mounting plate 12 on the vertical test bench 10 is provided with through holes 123 at the positions corresponding to the lifting plates 23. The threaded end of the drive screw 24 moves through the through hole 123 and then screws into the lifting plate 23.

[0034] The guide rod 22 is used to guide the sliding of the lifting plate 23. The lifting plate 23 abuts against the flange of the motor 30. Synchronous rotation of the drive screw 24 drives the lifting plate 23 to rise. Since the lifting plate 23 abuts against the lower side of the flange of the motor 30, the two lifting plates 23 together lift the motor 30, facilitating the installation of the motor 30. Alternatively, the motor 30 can be smoothly lowered during disassembly, making disassembly easier.

[0035] In this embodiment, see Figure 3 The lifting plate 23 includes a connecting part and a protruding part. The two ends of the connecting part are respectively provided with sliding holes 231. The protruding part is located in the middle of the connecting part and extends to one side. The protruding part is provided with a threaded hole 232. The two sliding holes 231 are respectively slidably connected to the guide rods 22 of each group. The drive screw 24 is threadedly connected to the threaded hole 232.

[0036] In this embodiment, see Figure 4 The drive screw 24 includes a screw body 241, a limiting rod 242, and a handle 244. The screw body 241 is fixed to one end of the limiting rod 242, and the handle 244 is installed on the other end of the limiting rod 242. The diameter of the limiting rod 242 is larger than the diameter of the screw body 241, thereby forming a step 243 at the end where the limiting rod 242 connects to the screw body 241. For use, see [reference needed]. Figure 6 The screw body 241 passes through the through hole 123, and the step 243 abuts against the upper side of the motor mounting plate 12. By rotating the handle 244, the screw body 241 is driven to rotate, thereby driving the lifting plate 23 to move up and down.

[0037] Example 2:

[0038] Based on Example 1, see Figure 1 , 3 The base 21 is slidably connected to the base plate 11 on the vertical test bench 10 via a sliding structure 40. The base 21 can slide directionally on the base plate 11, thereby facilitating the movement of the motor 30 into the vertical test bench 10.

[0039] In this embodiment, the sliding structure 40 includes linear guide rails 41 and sliders 42. Two linear guide rails 41 are spaced apart and parallel to each other on the base plate 11. At least one slider 42 is slidably mounted on the linear guide rails 41. One end of the base 21 is fixedly mounted on the slider 42, and the other end of the base 21 is cantilevered. The guide rod 22 is mounted on the cantilevered end of the base 21. When the cantilevered end of the base 21 extends, it facilitates placing the motor 30 onto the base 21. Then, by pushing the motor 30, the base 21 moves along the linear guide rails 41, thereby moving the motor 30 into the vertical test bench 10. Figure 6 As shown.

[0040] Furthermore, two stops 43 are fixedly installed at both ends of the linear guide rail 41 to limit the base 21 and prevent the slider 42 from disengaging from the linear guide rail 41.

[0041] In this embodiment, see Figure 1 When slider 42 abuts against stop 43 on the right, the base 21 extends to its maximum length. See also Figure 6 When the slider 42 abuts against the left stop 43, the motor 30 is roughly aligned with the shaft hole 121 on the motor mounting plate 12.

[0042] Furthermore, a positioning device is also installed on the base 21. The positioning device facilitates the positioning of the motor 30, so that when the slider 42 abuts against the left stop 43, the output shaft of the motor 30 is aligned with the shaft hole 121 on the motor mounting plate 12.

[0043] In this embodiment, see Figure 3 , 5 The positioning device is a limit ring 25.

[0044] Further, see Figure 5 The inner hole of the limiting ring 25 is a tapered hole 251 that is larger at the top and smaller at the bottom, which facilitates the insertion of the motor 30.

[0045] The steps for using this utility model are as follows:

[0046] When using, please refer to Figure 1 When one cantilevered end of the base 21 extends, the motor 30 is placed on the base 21. Then, the motor 30 is pushed, and the base 21 moves along the linear guide rail 41, thereby moving the motor 30 into the vertical test bench 10, as shown. Figure 6 As shown.

[0047] See also Figure 6 The screw body 241 of the drive screw 24 is passed through the through hole 123, and the step 243 abuts against the upper side of the motor mounting plate 12. By rotating the handle 244, the screw body 241 is driven to rotate, thereby causing the lifting plate 23 to move upward. As the drive screw 24 rotates further, see... Figure 7 Since the lifting plate 23 abuts against the lower side of the flange of the motor 30, the two lifting plates 23 drive the motor 30 to rise until the flange of the motor 30 abuts against the lower side of the motor mounting plate 12, which facilitates the installation of the motor 30.

[0048] When disassembling the motor 30, remove the bolts connecting the motor 30 to the motor mounting plate 12, and rotate the drive screw 24 in the opposite direction to allow the motor 30 to descend smoothly, facilitating the disassembly of the motor 30.
