Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a wind turbine centering tool. Background Technology

[0002] Currently, the mainstream air conditioner fan is the EC fan. EC fans are used with a guide vane. Because the guide vane is not an integral part of the fan structure, during fan installation, the center of the guide vane needs to be aligned with the center of the fan to ensure sufficient clearance between the guide vane and the fan impeller, preventing the fan impeller from rubbing against the guide vane during operation. Currently, the current method of integrating the EC fan and guide vane into a single unit within the air conditioner structure requires numerous parts, resulting in high cost, complex operation, and poor alignment. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing air conditioning structure, which requires a large number of parts to form an integrated EC fan and air guide ring, resulting in high cost, complicated operation and poor alignment effect. The present invention provides a fan alignment tooling.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fan centering fixture for installing a guide ring on a fan. The fan has an impeller and includes several gripper mechanisms fixed on the impeller. The gripper mechanism includes an upper gripper assembly for gripping the guide ring and a lower gripper assembly for gripping the impeller. The end of the upper gripper assembly is used to fit against the outer edge surface of the impeller, and the end of the lower gripper assembly is used to fit against the inner wall of the guide ring, so that the guide ring is installed on the fan. By using the lower gripper assembly to fit against the outer edge of the impeller and installing the gripper mechanism onto the fan, and then using the upper gripper assembly to fit against the inner wall of the air guide ring and clamp the air guide ring onto the gripper mechanism, the operation of installing the air guide ring onto the fan can be completed. This effectively solves the alignment problem between the fan and the air guide ring, thereby ensuring the alignment effect between the fan and the air guide ring while reducing the required parts, lowering costs, simplifying the fan installation operation, and improving installation efficiency.

[0005] Furthermore, the fan alignment fixture also includes a first semi-circular ring, a second semi-circular ring, and a rotating shaft for rotatably connecting the first and second semi-circular rings. Several gripper mechanisms are arranged on the first and second semi-circular rings. After the air guide ring is installed on the fan via the gripper mechanisms and alignment is ensured, the air guide ring and the fan, connected by the gripper mechanisms, are installed as a whole inside the air conditioning unit. Then, the rotating shaft is used to rotatably connect the first and second semi-circular rings, and the fan alignment fixture is removed from the air guide ring and the fan, thereby effectively improving the convenience of removing the fan alignment fixture.

[0006] Furthermore, the lower gripper assembly includes a lower limiting portion, a lower gripper body for abutting against the outer edge surface of the fan, and a lower spring for elastically connecting the lower gripper body to the lower limiting portion. By engaging the lower gripper body of the lower gripper assembly with the outer edge surface of the impeller and applying inward pressure to the outer edge surface of the impeller using the elastic force of the lower spring, the operation of clamping the impeller with the lower gripper assembly can be realized, thereby realizing the operation of engaging the annular component formed by the first and second semi-circular components of the fan centering fixture onto the fan.

[0007] Furthermore, the lower gripper body has a lower abutment portion, which is arc-shaped. By setting the shape of the lower abutment portion to arc, the fit between the lower abutment portion and the outer edge surface of the fan impeller can be effectively improved, thereby effectively improving the stability of clamping the fan using the lower abutment portion, and further improving the stability of fixing the fan centering fixture to the fan.

[0008] Furthermore, the lower abutment portion includes a lower elastic element, which abuts against the outer edge surface of the fan. The fan centering fixture provided by this utility model can also ensure the fit between the lower abutment portion and the outer edge surface of the fan impeller by placing an elastic element such as a sponge pad between the lower abutment portion and the fan impeller, thereby effectively improving the stability of clamping the fan using the lower abutment portion, and further improving the stability of the fan centering fixture fixed to the fan. It also provides multiple implementation methods to meet the usage needs in different scenarios.

[0009] Furthermore, the upper gripper assembly includes an upper limit stop, an upper gripper body for abutting against the inner wall of the air guide ring, and an upper spring for elastically connecting the upper gripper body to the upper limit stop. By engaging the upper gripper body of the upper gripper assembly with the inner wall of the air guide ring and applying outward pressure to the inner wall of the air guide ring using the elastic force of the upper spring, the operation of clamping the air guide ring with the upper gripper assembly can be realized, thereby realizing the operation of installing the air guide ring onto the fan using the air guide ring centering fixture.

[0010] Furthermore, the upper gripper body has an upper abutment portion that abuts against the inner wall of the air guide ring, and the upper abutment portion is arc-shaped. By setting the shape of the upper abutment portion to arc, the fit between the upper abutment portion and the inner wall of the air guide ring can be effectively improved, thereby effectively improving the stability of clamping the air guide ring using the upper abutment portion, and further improving the stability of installing the air guide ring onto the fan using this air guide ring centering fixture.

[0011] Furthermore, the upper abutment portion includes an upper elastic element, which abuts against the inner wall of the air guide ring. The air guide ring centering fixture provided by this utility model can also ensure the fit between the upper abutment portion and the inner wall of the air guide ring by placing an elastic element such as a sponge pad between the upper abutment portion and the air guide ring, thereby effectively improving the stability of clamping the air guide ring using the upper abutment portion. This further improves the stability of installing the air guide ring onto the fan using the air guide ring centering fixture, and provides multiple implementation methods to meet the usage needs in different scenarios.

[0012] Furthermore, this utility model also provides a fan centering fixture. The upper gripper assembly includes an upper limit portion, an upper gripper body that abuts against the inner wall of the guide ring, and an upper spring for elastically connecting the upper gripper body to the upper limit portion. The lower gripper assembly includes a lower limit portion, a lower gripper body that abuts against the outer edge surface of the fan, and a lower spring for elastically connecting the lower gripper body to the lower limit portion. By engaging the lower gripper body of the lower gripper assembly with the outer edge surface of the impeller and applying inward pressure to the outer edge surface of the impeller using the elastic force of the lower spring, the operation of clamping the impeller with the lower gripper assembly can be realized, thereby realizing the operation of engaging the ring formed by the first and second semi-circular ring parts of the fan centering fixture onto the fan. By inserting the upper jaw body of the upper jaw assembly into the inner wall of the air guide ring and applying outward pressure to the inner wall of the air guide ring using the elastic force of the upper spring, the operation of clamping the air guide ring with the upper jaw assembly can be realized, thereby realizing the operation of installing the air guide ring on the fan using the air guide ring centering fixture.

[0013] Furthermore, the bottom of the lower limiting part also has a lower fixing claw. By engaging the outer edge of the fan impeller between the lower fixing claw and the lower abutment part of the lower limiting part, the claw mechanism can be engaged and fixed on the fan, effectively ensuring stability. This provides multiple implementation methods for fixing the claw mechanism on the fan, meeting the usage needs of different scenarios.

[0014] The beneficial effects of the fan centering fixture provided by this utility model are as follows: By using the lower gripper assembly to adhere to the outer edge of the impeller and install the gripper mechanism on the fan, and then using the upper gripper assembly to adhere to the inner wall of the air guide ring and clamp the air guide ring onto the gripper mechanism, the operation of installing the air guide ring on the fan can be completed, effectively solving the centering problem between the fan and the air guide ring. This effectively ensures the centering effect of the fan and the air guide ring while reducing the required parts, lowering costs, simplifying the fan installation operation, and improving installation efficiency. Furthermore, after installing the air guide ring onto the fan through the gripper mechanism and ensuring the centering effect, the air guide ring and the fan, connected by the gripper mechanism, are installed as a whole inside the air conditioning unit. Then, a rotating shaft is used to rotate and connect the first and second semi-circular rings, allowing the fan centering fixture to be removed from the air guide ring and the fan, thus effectively improving the convenience of removing the fan centering fixture.
