Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a motor clamp that is easy to clamp. Background Technology

[0002] Permanent magnet synchronous motors are a type of AC motor that are widely used due to their high efficiency, energy saving, fast response speed, and good operational stability.

[0003] After the permanent magnet synchronous motor is manufactured, it needs to undergo tests such as energy efficiency testing, withstand voltage testing, and radial runout testing. During these tests, the motor needs to be fixed in place. The existing method of fixing the motor is generally to lock it with bolts. This method is time-consuming and labor-intensive, and requires a long working time. In addition, after the test is completed, each bolt needs to be unscrewed one by one, which is extremely cumbersome. Therefore, an improvement is needed. Utility Model Content

[0030] Reference Figures 1-4According to an embodiment of the present invention, an easy-to-clamp motor clamp includes a base 11, on which two clamping assemblies are arranged in a left-right distribution. It also includes a locking mechanism for controlling the two clamping assemblies to move toward each other. After the clamping assemblies are adjusted to the correct angle, the operator can place the motor on the base 11 and use the locking mechanism to bring the clamping assemblies closer to each other. At this time, the clamping assemblies can lock the motor.

[0031] In this embodiment, the clamping assembly includes a sliding plate 21, with a horizontal plate 22 on the side of the sliding plate 21. Two horizontal plates 22 are fixed to the sides of the two sliding plates 21 that are close to each other. A slot 23 is provided in the lower side of the horizontal plate 22. A lifting plate 24 is slidably connected to the slot 23. Several upper pressure plates 25 are slidably connected to the lifting plate 24. The assembly also includes an adjustment mechanism for controlling the vertical position of the lifting plate 24 and the front-back position of the upper pressure plates 25. The operator can adjust the front-back position and vertical height of the upper pressure plates 25 according to the size and height of the motor mounting plate 91 to be clamped and the arrangement of the reinforcing ribs or connecting plates 92 between the motor housing and the base plate. The adjustment mechanism is used to lock the upper pressure plates 25. When the left and right upper pressure plates 25 approach each other and press against the motor mounting plate, the motor is locked.

[0032] The locking mechanism includes an inner cavity 31 located in the bottom surface of the base 11, and a control shaft 32 is rotatably connected inside the inner cavity 31. The control shaft 32 has two opposite threads machined inside.

[0033] The upper side of the base 11 is provided with a sliding groove that extends into the inner cavity 31. The lower side of the slide plate 21 is provided with a control plate 33 that extends through the sliding groove into the inner cavity 31. The two control plates 33 are respectively threaded to two threads in the control shaft 32. A handwheel 34 is installed at one end of the control shaft 32 that extends outside the base 11.

[0034] The operator can crank the handwheel 34 to rotate the control shaft 32, at which time the control plate 33 can drive the slide plate 21 and the upper pressure plate 25 to move in opposite directions.

[0035] To facilitate the upper pressure plate 25 pressing against the mounting plate inside the motor, an extension plate is integrally formed on the side of the upper pressure plate 25 away from and close to the sliding plate 21. The extension plate extends laterally to the outside of the horizontal plate 22. That is, the extension plate replaces the upper pressure plate 25 to press the motor, avoiding the situation where the motor housing interferes with the movement of the horizontal plate 22, thus preventing the upper pressure plate 25 from pressing against the mounting plate inside the motor.

[0036] In addition, a retaining plate 61 extending in the front-to-back direction is provided on the lower side of the extension plate. The retaining plate 61 can abut against the left and right edges of the motor mounting plate. When the two retaining plates 61 on the left and right sides are close to each other, they can straighten the angle of the motor.

[0037] The adjustment mechanism includes a first bolt 41 rotatably connected to the horizontal plate 22, the first bolt 41 being threadedly connected to the lifting plate 24, and a first slide rod 42 inserted into the lifting plate 24 is provided on the upper side of the slot 23.

[0038] The two slide plates 21 are provided with extrusion grooves 26 on their sides that are close to each other. Side pressure plates 27 are slidably connected to the extrusion grooves 26. The side pressure plates 27 press against the upper pressure plate 25. The slide plates 21 are rotatably connected to the side pressure plates 27 with a second bolt 28 threaded to the side pressure plates 27. The side of the extrusion grooves 26 is also provided with a second slide rod 29 that is inserted into the side pressure plates 27.

[0039] The operator can rotate the first bolt 41 to adjust the vertical position of the lifting plate 24, the upper pressure plate 25, and the extension plate to match the height of the motor mounting plate. After adjusting the front and rear positions of each upper pressure plate 25, the operator can rotate the second bolt 28 to clamp the upper pressure plate 25 between the side pressure plate 27 and the side of the slot 23, and lock the front and rear positions of each upper pressure plate 25 to match the position of the reinforcing plate or reinforcing rib inside the motor mounting plate.

[0040] In addition, to further increase friction, vertical lines distributed front and back are provided on the sides of the upper pressure plate 25 and the side pressure plate 27 that are in contact with each other.

[0041] The inner cavity 31 is also provided with a third sliding rod that passes through the control plate 33, so that the sliding plate 21 can move stably.

[0042] Clamping process:

[0043] First, the staff adjusts the height of the upper pressure plate 25 and the front-to-back position of the upper pressure plate 25 relative to the lifting plate 24 according to the height of the motor mounting plate and the position of the reinforcing ribs, connecting plate 92 or reinforcing plate between the mounting plate and the motor housing.

[0044] When clamping, the operator places the motor on the base 11 and rotates the handwheel 34. At this time, the two adjusted upper pressure plates 25 and the extension plate can approach each other and press against the upper side of the motor mounting plate. The front and rear edges of the upper pressure plates 25 can abut against the reinforcing ribs or connecting plates of the motor mounting plate to prevent the motor from moving forward and backward or up and down when it is powered on. When the upper pressure plates 25 approach each other, the clamping plate 61 can stick to the left and right sides of the motor mounting plate to straighten the motor and prevent the motor from moving left and right.

[0045] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
