Description
Technical fields:
[0001] This utility model relates to a multi-machine joint commissioning assembly tool. Background technology:
[0002] With social development and progress, motor manufacturing technology is becoming increasingly sophisticated. To improve motor performance, the requirements for the processing and manufacturing precision of various motor components are also increasing. Motor frequency conversion is constantly developing with social progress and technological updates. To verify the performance of motor frequency conversion equipment, multi-machine joint debugging tests are required. Previous technical methods can no longer meet the testing needs of motors. The emergence of new motor frequency conversion equipment and motor usage methods has rendered the derived process technology solutions inapplicable. Therefore, a new tooling is needed to meet and ensure the production needs of the new technical solutions. Summary of the Invention:
[0003] The purpose of this utility model is to provide a multi-machine joint commissioning assembly tool that can meet the performance test requirements for verifying the overall operation of the motor frequency converter and the motor, thereby improving the overall performance of the motor manufacturing and operation. The technical solution of this utility model is: a multi-machine joint commissioning assembly tool, which is assembled by using a coupling (1), a transition plate (2), a transmission positioning pin (3), a fastening bolt (4) and an anti-loosening washer (5). The transition plate (2) is fixed to the motor shaft head (6) by the fastening bolt (4). The fastening bolt (4) is equipped with an anti-loosening washer (5) to prevent the fastening bolt (4) from loosening. Both the transition plate (2) and the motor shaft head (6) have light holes (7) for installing the transmission positioning pin (3). The transmission positioning pin (3) is installed in the light holes (7). The coupling (1) and the transition plate (2) are fitted and fastened by the fastening bolt (4).
[0004] The working principle of this utility model is as follows:
[0005] First, the transition plate is fixed to the motor shaft head with fastening bolts, and anti-loosening washers are used to prevent the fastening bolts from loosening. Then, the transition plate and the motor shaft head are machined with holes for installing the transmission positioning pin, and the transmission positioning pin is installed in the holes. Finally, the coupling and the transition plate are assembled and installed, and fastened with fastening bolts. Anti-loosening washers are used to prevent the fastening bolts from loosening. This utility model is suitable for multi-machine joint commissioning and can well ensure that the shafts of multiple machines maintain stable alignment performance. Moreover, the transmission positioning pin structure does not require keyways to be cut on the shaft diameter, effectively ensuring the overall strength of the shaft.
[0006] The specific usage process of the tool can be referred to the following example: Fix the transition plate to the motor shaft head with fastening bolts, and use anti-loosening washers to prevent the fastening bolts from loosening. Then, machine the transition plate and the motor shaft head with open holes for installing the transmission positioning pin, and install the transmission positioning pin in them. Finally, assemble and install the coupling with the transition plate, and tighten it with fastening bolts. Anti-loosening washers prevent the fastening bolts from loosening. This utility model is suitable for multi-machine joint commissioning, and can well ensure that the shafts of multiple machines maintain stable alignment performance. Moreover, the transmission positioning pin structure does not require keyways to be cut on the shaft diameter, effectively ensuring the overall strength of the shaft.
[0007] The beneficial effects of this utility model are:
[0008] This utility model uses an anti-loosening washer (5) to prevent the fastening bolt (4) from loosening. This utility model is suitable for multi-machine joint operation and can well ensure the stable centering performance of the shafts of multiple machines. Moreover, the transmission positioning pin (3) structure does not require keyways to be made on the shaft diameter, which effectively ensures the overall strength of the shaft. Cylindrical pins are used for transmission and center positioning between motors. This not only avoids the damage to the overall strength of the shaft by making transmission keyways on the shaft, but also meets the high torque transmission after the motors are assembled. The center positioning effect is excellent, the structure is simple, the appearance is beautiful, and the economic benefits are great. This connection transmission structure avoids the problem of motor damage and insufficient transmission torque caused by excessive clearance in key transmission. Moreover, the operation is simple, the pin installation is convenient and simple, and the specifications and quantity of the pins can be appropriately changed according to the changes in transmission torque, avoiding the increase of the radial dimension of the mating shaft and reducing production costs.
[0009] In the past, key drives or interference fits in motor couplings required widening the keyway and key dimensions or increasing the interference fit dimensions when operating at high torque. Widening the keyway and key dimensions would result in excessively large shaft and coupling dimensions to meet strength requirements, increasing production costs. Increasing the interference fit dimensions would lead to excessively high temperatures during heat fitting, wasting resources and making disassembly difficult, thus increasing the workload. Therefore, the pin drive method can perfectly solve the above-mentioned traditional problems. Attached Figure Description
