Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment installation, and in particular to an auxiliary device for electromechanical equipment installation. Background Technology

[0002] Electromechanical equipment is a general term for mechanical and electrical equipment. It encompasses a variety of equipment and devices used in different fields. These devices are usually composed of multiple modules with different functions. During installation, it is necessary to assemble the modules with different functions together. For example, when assembling a blower, the drive module (motor), the casing module (housing), and the suction module (impeller) need to be assembled together. The impeller and the housing are usually connected together by a mounting shaft during production, while the motor requires an additional assembly process.

[0003] When installing the motor of a blower, the key on the motor output shaft must first be inserted into the keyway of the mounting shaft of the housing, and then the motor and housing are installed together with bolts. The current method typically involves the operator using a clamping device to hold the housing in place, aligning the key on the motor output shaft with the keyway of the mounting shaft, and finally inserting the key into the keyway and tightening the bolts with an electric screwdriver. This method requires multiple adjustments to the position of the key on the motor output shaft and the keyway of the mounting shaft, making alignment cumbersome and hindering the restraint of the motor components. The motor components are also prone to displacement during bolt installation, requiring frequent alignment of the screw holes on the motor and housing, resulting in low installation efficiency. Utility Model Content

[0004] To overcome the drawbacks of traditional methods, such as the cumbersome alignment of the motor's flat key with the keyway of the housing mounting shaft, the difficulty in limiting the position of the motor workpiece, the tendency for the motor workpiece to shift during bolt installation, the need for frequent alignment of the screw holes on the motor and housing, and the low installation efficiency, this utility model provides an auxiliary device for electromechanical equipment installation that can quickly align the motor's flat key with the keyway of the housing mounting shaft in one go, facilitate the limiting of the motor workpiece, increase the stability of the motor workpiece during bolt installation, and improve installation efficiency.

[0005] The technical solution of this utility model is as follows: an auxiliary device for installing electromechanical equipment, including a base frame, a guide frame fixedly connected to the top of the base frame, a guide rail fixedly connected to the top of the base frame, a first placement frame slidably connected to the guide rail, a second placement frame fixedly connected to the top of the base frame, a motor workpiece placed in the first placement frame, a flat key provided on the output shaft of the motor workpiece, a housing placed in the second placement frame, a mounting shaft provided on one side of the housing, a keyway provided in the mounting shaft of the housing, a lifting mechanism provided on the base frame, a calibration mechanism provided on the lifting mechanism, the lifting mechanism being used to drive the calibration mechanism to lift and lower, and the calibration mechanism being used to calibrate the flat key of the motor workpiece and the keyway of the housing.

[0006] Furthermore, the lifting mechanism includes electric push rods, and two electric push rods are fixedly connected to the top of the base frame. The two electric push rods are symmetrically arranged, and a transmission frame is fixedly connected between the top of the telescopic rods of the two electric push rods. The transmission frame is slidably connected to the guide frame, and a sliding frame is slidably connected to the transmission frame. A horizontal spring is provided between the sliding frame and the transmission frame.

[0007] Furthermore, the calibration mechanism includes a rotating body, which is rotatably connected to the lower part of the sliding frame. One end of the rotating body is fixedly connected to a rotating shaft, and one end of the rotating shaft has a circular hole. A calibration block is slidably connected inside the circular hole of the rotating shaft. The calibration block has an inclined surface. Two return springs are provided between the calibration block and the rotating shaft. The other end of the rotating body is fixedly connected to a rotating shaft. The mounting shaft of the housing, the rotating body, the rotating shaft, the rotating shaft, and the output shaft of the motor workpiece are located on the same axis. One end of the rotating shaft is slidably connected to a calibration block. The calibration block has an inclined surface. A return spring is provided between the calibration block and the rotating shaft. A drive assembly is provided at the bottom of the sliding frame.

[0008] Furthermore, the drive assembly includes a servo self-locking motor, the servo self-locking motor is fixedly connected to the bottom of the sliding frame, a gear one is fixedly connected to the output shaft of the servo self-locking motor, a gear two is fixedly connected to the rotating body, and the gear one meshes with the gear two.

[0009] Furthermore, it also includes a limiting mechanism. The limiting mechanism is provided on the first placement frame and is used to limit the motor workpiece. The limiting mechanism includes a slot frame. Two slot frames are fixedly connected to the base frame. The two slot frames are symmetrically arranged. Each slot frame has a limiting groove. Two limiting plates are slidably connected to the first placement frame. The two limiting plates are symmetrically arranged. A contact shaft is fixedly connected to the bottom of each of the two limiting plates. The lower ends of the two contact shafts are respectively located in the limiting grooves of the two slot frames.

[0010] The beneficial effects of this utility model are as follows: 1. When calibration block one disengages from the flat key of the motor workpiece, reset spring one will rebound and drive calibration block one to return downward. Calibration block one continues to rotate and contact the flat key of the motor workpiece, and drives the flat key of the motor workpiece to rotate vertically upward. When calibration block two rotates to the keyway of the housing mounting shaft, reset spring two will rebound and drive calibration block two to return and extend from the rotating shaft two. Calibration block two will lock the keyway of the housing mounting shaft and drive the housing mounting shaft to rotate until the keyway of the housing mounting shaft is vertically upward. This can quickly align the flat key of the motor workpiece with the keyway of the housing mounting shaft in one go, improving installation efficiency.

[0011] 2. The placement frame drives two limiting plates to move horizontally, which in turn drives two contact shafts to move horizontally. The limiting grooves of the slot frame press against the contact shafts, causing the two contact shafts to move closer to each other. The two contact shafts then drive the two limiting plates to move closer to each other. The two limiting plates contact the motor workpiece and limit its movement, which facilitates the limiting of the motor workpiece, increases the stability of the motor workpiece when installing bolts, and further improves installation efficiency.

However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] Example 1: An auxiliary device for the installation of electromechanical equipment, such as Figures 1-5 As shown, the device includes a base frame 1, a guide frame 2 welded to the top of the base frame 1, a guide rail 3 fixedly connected to the top of the base frame 1, a first placement frame 4 slidably connected to the guide rail 3 for guiding the first placement frame 4, a second placement frame 5 bolted to the top of the base frame 1, a motor workpiece 6 placed inside the first placement frame 4, a flat key provided on the output shaft of the motor workpiece 6, a housing 7 placed inside the second placement frame 5, a mounting shaft provided on one side of the housing 7, a keyway provided in the mounting shaft of the housing 7, a lifting mechanism provided on the base frame 1, a calibration mechanism provided on the lifting mechanism, the lifting mechanism for driving the calibration mechanism to move up and down, and the calibration mechanism for calibrating the flat key of the motor workpiece 6 and the keyway of the housing 7.

[0020] The lifting mechanism includes an electric push rod 8. Two electric push rods 8 are fixedly connected to the top of the base frame 1. The two electric push rods 8 are symmetrically arranged. A transmission frame 9 is fixedly connected between the top of the telescopic rods of the two electric push rods 8. The electric push rods 8 are used to drive the transmission frame 9 to move. The transmission frame 9 is slidably connected to the guide frame 2. The guide frame 2 is used to guide the transmission frame 9. A sliding frame 10 is slidably connected to the transmission frame 9. A horizontal spring 11 is provided between the sliding frame 10 and the transmission frame 9.

[0021] The calibration mechanism includes a rotating body 12, which is rotatably connected to the lower part of the sliding frame 10. A rotating shaft 13 is fixed to one end of the rotating body 12, and a circular hole is formed at one end of the rotating shaft 13. A calibration block 14 is slidably connected within the circular hole of the rotating shaft 13. The rotating body 12 drives the calibration block 14 to rotate via the rotating shaft 13, thereby calibrating the flat key of the motor workpiece 6. The calibration block 14 has an inclined surface, and two return springs 15 are provided between the calibration block 14 and the rotating shaft 13. The other end is fixedly connected to a second rotating shaft 16. The mounting shaft of the housing 7, the rotating body 12, the first rotating shaft 13, the second rotating shaft 16, and the output shaft of the motor workpiece 6 are located on the same axis. One end of the second rotating shaft 16 is slidably connected to a second calibration block 17. The second calibration block 17 is provided with an inclined surface. The rotating body 12 drives the second calibration block 17 to rotate through the second rotating shaft 16, thereby calibrating the keyway of the mounting shaft of the housing 7. A second return spring 18 is provided between the second calibration block 17 and the second rotating shaft 16. The bottom of the sliding frame 10 is provided with a drive assembly.

[0022] The drive assembly includes a servo self-locking motor 19, which is fixedly connected to the bottom of the sliding frame 10. A gear 20 is fixedly connected to the output shaft of the servo self-locking motor 19, and a gear 21 is fixedly connected to the rotating body 12. The gear 20 meshes with the gear 21. The servo self-locking motor 19 drives the gear 21 to rotate through the gear 20, thereby driving the rotating body 12 to rotate.

[0023] Initially, the servo self-locking motor 19 locks gear 20, which in turn locks gear 21, rotating body 12, rotating shaft 13, calibration block 14, return spring 15, rotating shaft 16, calibration block 17, and return spring 18. The operator places the motor workpiece 6 onto the placement rack 4, and then places the housing 7 onto the placement rack 5, ensuring that the mounting shaft of the housing 7, rotating body 12, rotating shaft 13, rotating shaft 16, and the output shaft of the motor workpiece 6 are on the same axis. After the motor workpiece 6 and housing 7 are in place, the operator pushes the placement rack 4, which moves horizontally along the guide rail 3, causing the motor workpiece 6 to move closer to the housing 7. The output shaft of the motor workpiece 6 then enters the circular hole of rotating shaft 13. The flat key of part 6 contacts the inclined surface of calibration block 14, pressing calibration block 14 upward. The return spring 15 is stretched, and the motor part 6 continues to move, driving the rotating shaft 13 to move horizontally. The horizontal movement of the rotating shaft 13 drives calibration block 14, return spring 15, and rotating body 12 to move horizontally. The horizontal movement of the rotating body 12 drives the sliding frame 10, rotating shaft 16, calibration block 17, return spring 18, servo self-locking motor 19, gear 120, and gear 21 to move horizontally. The horizontal spring 11 is compressed, and rotating shaft 16 enters the mounting shaft of housing 7. The edge of the mounting shaft of housing 7 contacts the inclined surface of calibration block 17, pressing calibration block 17 downward. Calibration block 17 retracts downward into rotating shaft 16, and the return spring 18... After being compressed, the staff stopped moving the placement rack 4 and then started the servo self-locking motor 19 to rotate one revolution. The output shaft of the servo self-locking motor 19 rotated, driving gear 20 to rotate. Gear 20 rotated, driving gear 21 to rotate. Gear 21 rotated, driving rotating body 12 to rotate. Rotating body 12 rotated, driving rotating shaft 13 and rotating shaft 16 to rotate. Rotating shaft 13 rotated, driving calibration block 14 and return spring 15 to rotate. Calibration block 14 rotated and disengaged from the flat key of the motor workpiece 6. Return spring 15 rebounded and drove calibration block 14 to return downward. Calibration block 14 continued to rotate and contacted the flat key of the motor workpiece 6, driving the flat key of the motor workpiece 6 to rotate vertically upward. Rotating shaft 16 rotated, driving calibration block 17... When the reset spring 18 rotates and the calibration block 17 rotates to the keyway of the mounting shaft of the housing 7, the reset spring 18 will rebound and drive the calibration block 17 to return to its original position and extend from the rotating shaft 16. The calibration block 17 will then lock into the keyway of the mounting shaft of the housing 7 and drive the mounting shaft of the housing 7 to rotate until the keyway of the mounting shaft of the housing 7 is vertically upward. Through the above operation, the flat key of the motor workpiece 6 can be quickly aligned with the keyway of the mounting shaft of the housing 7 in one go, improving installation efficiency. After the flat key of the motor workpiece 6 is aligned with the keyway of the mounting shaft of the housing 7, the operator pushes the placement bracket 4 in the opposite direction to move the motor workpiece 6 in the opposite direction a certain distance, so that the output shaft of the motor workpiece 6 leaves the round hole of the rotating shaft 13. After the output shaft of the motor workpiece 6 is no longer in contact with the rotating shaft 13,The horizontal spring 11 will rebound and drive the sliding frame 10 to move in the opposite direction. The reverse movement of the sliding frame 10 will drive the rotating body 12 to move in the opposite direction. The reverse movement of the rotating body 12 will drive the rotating shaft 13, calibration block 14, return spring 15, rotating shaft 16, calibration block 17, return spring 18, servo self-locking motor 19, gear 1 20, and gear 2 21 to move in the opposite direction. The rotating shaft 16 will move away from the mounting shaft of the housing 7. Then, the operator will activate the extension rod of the hydraulic push rod to extend upward. The extension rod of the hydraulic push rod will move upward, driving the transmission frame 9 to move upward. The upward movement of the transmission frame 9 causes the sliding frame 10 and the horizontal spring 11 to move upward. The upward movement of the sliding frame 10 causes the rotating body 12 to move upward. The upward movement of the rotating body 12 causes the rotating shaft 13, calibration block 14, return spring 15, rotating shaft 16, calibration block 17, return spring 18, servo self-locking motor 19, gear 1 20, and gear 2 21 to move upward. Through the above operations, the position of the calibration mechanism can be moved upward, avoiding obstruction when the calibration mechanism is installed between the motor workpiece 6 and the housing 7. Then, the staff can... Next, the placement rack 4 is pushed horizontally, causing the motor workpiece 6 to move closer to the housing 7. The output shaft of the motor workpiece 6 will insert into the mounting shaft of the housing 7, and the flat key of the motor workpiece 6 will lock into the keyway of the mounting shaft of the housing 7. Then, the operator inserts the bolts one by one into the pre-drilled screw holes on the motor workpiece 6 and the housing 7, and then tightens the bolts with an electric screwdriver to complete the installation of the motor workpiece 6 and the housing 7. After the installation is completed, the operator removes the connected motor workpiece 6 and housing 7, and then pushes the placement rack 4 away from the placement rack 5. After the placement frame 4 resets, the operator adjusts the extension rod of the hydraulic push rod to retract downwards. The downward movement of the extension rod causes the transmission frame 9 to move downwards. The downward movement of the transmission frame 9 causes the sliding frame 10 and the horizontal spring 11 to move downwards. The downward movement of the sliding frame 10 causes the rotating body 12 to move downwards. The downward movement of the rotating body 12 causes the rotating shaft 13, calibration block 14, reset spring 15, rotating shaft 16, calibration block 17, reset spring 18, servo self-locking motor 19, gear 120, and gear 21 to move downwards.

[0024] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 5As shown, it also includes a limiting mechanism. The limiting mechanism is provided on the placement frame 4. The limiting mechanism is used to limit the motor workpiece 6. The limiting mechanism includes a slot frame 22. Two slot frames 22 are welded on the base frame 1. The two slot frames 22 are symmetrically arranged. Each slot frame 22 has a limiting groove. Two limiting plates 23 are slidably connected to the placement frame 4. The two limiting plates 23 are symmetrically arranged. The bottom of each limiting plate 23 is fixedly connected to a contact shaft 24. The lower ends of the two contact shafts 24 are respectively located in the limiting grooves of the two slot frames 22. The slot frame 22 drives the contact shafts 24 to move, thereby driving the limiting plates 23 to limit the motor workpiece 6.

[0025] Initially, the two limiting plates 23 are located on both sides of the motor workpiece 6, and the lower ends of the two contact shafts 24 are located in the limiting grooves of the two slot frames 22. After the motor workpiece 6 is placed, the placement frame 4 moves horizontally, causing the two limiting plates 23 to move horizontally. The horizontal movement of the two limiting plates 23 causes the two contact shafts 24 to move horizontally. The lower ends of the contact shafts 24 move along the limiting grooves of the slot frames 22, and the limiting grooves of the slot frames 22 press against the contact shafts 24. The two contact shafts 24 move towards each other, which in turn causes the two limiting plates 23 to move towards each other. Plate 23 moves toward each other and contacts the motor workpiece 6, limiting the motor workpiece 6. Through the above operation, it is easy to limit the motor workpiece 6, increase the stability of the motor workpiece 6 when installing bolts, and further improve the installation efficiency. The placement frame 4 moves in the opposite direction, causing the two limiting plates 23 to move in the opposite direction. The two limiting plates 23 move in the opposite direction, causing the two contact shafts 24 to move in the opposite direction. The limiting groove of the slot frame 22 squeezes the contact shafts 24 in the opposite direction. The two contact shafts 24 will move away from each other. The two contact shafts 24 moving away from each other will cause the two limiting plates 23 to move away from each other.
