Description

Technical Field

[0001] The utility model belongs to the technical field of permanent magnet motors, and particularly relates to an assembly platform for permanent magnet variable frequency motors. Background Art

[0002] Permanent magnet synchronous motors use permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates collector rings and brushes that are prone to problems, thereby improving the reliability of motor operation. Because no excitation current is required and there is no excitation loss, the efficiency and power density of the motor are improved. Permanent magnet synchronous motors are composed of stators, rotors, end covers and other components. The stator is basically the same as an ordinary induction motor, and a laminated structure is used to reduce iron loss during motor operation. The rotor can be made solid or laminated. The armature winding can be a concentrated full-pitch winding, a distributed short-pitch winding, or an unconventional winding. When the permanent magnet motor is assembled, a permanent magnet variable frequency motor assembly table is required.

[0003] The Chinese patent with publication number "CN215772867U" discloses a workbench for quick assembly of a permanent magnet motor, comprising a bottom plate, a vertical plate fixedly connected to one side of the top of the bottom plate, a top plate fixedly connected to one side of the outer wall of the vertical plate, and a servo motor rotatably connected to the inner wall of the top plate through a bearing. The utility model relates to the technical field of permanent magnet motors, and the workbench for quick assembly of permanent magnet motors.

[0004] However, this assembly table still has some shortcomings, because different types of permanent magnet motors have different sizes, and the structure for limiting the permanent magnet motor on the assembly table cannot adjust its own clamping width. Therefore, this assembly table can only limit the assembly of permanent magnet motors of a size that matches the clamping structure. If a larger permanent magnet motor is encountered, the user needs to replace the clamping mechanism, which reduces the assembly efficiency of the permanent magnet motor and also reduces the scope of use of the assembly table itself. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a permanent magnet variable frequency motor assembly platform to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

The user can start the telescopic cylinder to push the first clamp to move, and the first clamp will push the permanent magnet motor to the position of the second clamp. Under the clamping of the two, the position of the permanent magnet motor can be effectively limited. The slide groove can improve the stability of the bottom end of the first clamp without hindering the adjustment of the first clamp, thereby making the permanent magnet motor more stably clamped. At the same time, convenient adjustment of the position of the first clamp can achieve the purpose of conveniently adjusting the clamping space between the first clamp and the second clamp, thereby achieving the purpose of convenient clamping and limiting permanent magnet motors of different sizes.

[0008] As a preferred technical solution, one side of the first clamping plate and the other side of the second clamping plate are fixedly connected with rubber pads, and the rubber pads cover one side of the first clamping plate and the other side of the second clamping plate. The inner top end of the limit frame is fixedly connected with a sponge pad, and the sponge pad covers the inner top end of the limit frame. Due to the presence of the rubber pad, the rubber pad has a good anti-slip and shock-absorbing effect.

The bottom end of the support leg is coated with an anti-slip layer. Due to the presence of the support leg, the support leg can support the bottom end of the support platform, thereby effectively improving the stability of the bottom end of the support platform.

Due to the presence of the first telescopic rod 9 and the second telescopic rod 10, the two can be placed without interfering with each other. When the upper and lower positions of the top plate 7 are adjusted, the bottom end of the top plate 7 is effectively limited, thereby avoiding the angle deviation when adjusting the height of the top plate 7, and at the same time, the stability of the bottom end of the top plate 7 can be effectively improved.

While protecting the bottom end of the support platform 1, the stability of the bottom end of the support platform 1 is also improved. At the same time, due to the existence of the anti-skid pad 25, the anti-skid pad 25 can increase the friction between the ground and the anti-skid pad 25, thereby effectively improving the anti-skid ability of the bottom end of the support platform 1, thereby avoiding the displacement of the support platform 1.
