Description

Technical Field

[0001] The utility model relates to the technical field of stator insulation sleeve installation, in particular to a clamping device for stator insulation sleeve installation. Background Art

[0002] The motor stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. During the stator processing, the stator insulation sleeve installation equipment is required to insert the insulating paper sheet into the stator, that is, the stator insulation sleeve.

[0003] Patent No. CN202221629769.6 discloses an automatic installation device for insulating sheets for motor stators. When in use, the stator body 15 is first placed on the station seat 7, and then the two fastening screws 14 are screwed to loosen the limit block 8 and the slider 13. At this time, the limit block 8 is slid and adjusted along the slide groove 9 together with the slider 13, and the stator body 15 of different sizes is placed and clamped. Then the winding roller with the insulating paper sheet 20 wound around it is pulled out from the mounting platform 16 together with the insertion rod 17, so that the insulating paper sheet 20 pulled out can be kept in a straightened state, and then the two limit rollers 19 set on the movable rod 18 can be adjusted. The insulating paper sheet 20 in the straightened state is clamped in the middle position, and the motor 10, the electric telescopic rod 21 and the air pump 22 are started. When the motor 10 drives the rotating rod to drive the work station seat 7 to rotate, the rotating rod drives the work station seat 7 to rotate at a certain frequency, accompanied by the introduction of the insulating paper sheet 20. The extrusion plate 23 combines with the adaptor baffle 24 to extrude and cut the insulating paper sheet 20, and forms an adaptable shape that adapts to the mounting hole on the stator body 15 on the inner side of the adaptor baffle 24 with a concave structure. Finally, relying on the blowing of the air pump 22, the cut and formed insulating sheet is blown into the mounting hole on the stator body 15, and the operation is repeated in a cycle to complete the installation of the insulating sheet on the stator body 15.

[0004] The automatic installation device for insulating sheets for motor stators disclosed in the above patent uses a limit block 8 fixed by two tightening screws 14 to limit and clamp, and the clamping distance is fixed. It cannot automatically tighten and clamp accurately as the stator insulating sleeve shrinks during the unwinding process. Other existing clamping devices that can automatically tighten and clamp as the stator insulating sleeve shrinks during the unwinding process require electrical equipment to drive and key parts are not easy to quickly replace and repair. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 A clamping device for installing a stator insulating sleeve shown in the figure comprises a chassis 1, a fixing bolt 2 is fixedly connected at the axis center of the top of the chassis 1, three groups of rectangular slide grooves 5 are opened in a circular array on the top of the chassis 1, the rectangular slide grooves 5 extend from the edge of the chassis 1 to its axis center, and three groups of L-shaped clamping members 6 are slidably connected to the top of the chassis 1 through the rectangular slide grooves 5. The upper and lower ends of the L-shaped clamping members 6 that emerge from the rectangular slide grooves 5 are respectively installed with an upper limit plate 8 and a lower limit plate 10, a side ring 9 is fixedly installed at the bottom edge of the chassis 1, and a spring 13 is detachably installed between the lower part of the L-shaped clamping member 6 and the inner side wall of the side ring 9. The clamping device for installing a stator insulating sleeve of the utility model can clamp the stator insulating sleeve at three points on the stator insulating sleeve installation disk to prevent the disk from falling apart during installation, and no electrical equipment is required. Mechanical elastic clamping saves power resources, and the key component spring 13 is easy to replace and easy to repair.

[0021] Furthermore, a collar 3 is detachably mounted on the top of the chassis 1 through a fixing bolt 2, and an insulating sleeve 4 is wound around the outer wall of the collar 3, which is convenient for installation or removal; further, the length of the L-shaped clamp 6 extending from the top of the chassis 1 is exactly equal to the height of the insulating sleeve 4, so that the L-shaped clamp 6 clamps the side and top edges of the insulating sleeve 4 and clamps them firmly; further, the upper limit plate 8 is installed at the upper end tail of the rectangular slide groove 5 protruding from the L-shaped clamp 6, which has a good limiting effect and prevents the insulating sleeve 4 from being pressed by the insulating sleeve 4. Top height; further, the inner wall of the L-shaped clamp 6 is sprayed with a smooth layer 7 for reducing friction. The smooth coating on the inner wall of the L-shaped clamp 6 reduces the friction coefficient, which can ensure that the L-shaped clamp 6 can stably clamp the insulating sleeve 4, and the wound insulating sleeve can be smoothly pulled out and installed by the installation equipment; further, both ends of the spring 13 are welded with inserts 12, and the inserts 12 at both ends of the spring 13 are respectively inserted into the inner wall of the side ring 9 and the insert sleeve 11 fixedly installed at the tail of the L-shaped clamp 6, so as to facilitate the quick replacement of the spring 13.

[0022] In this solution, when in use, the stator insulation sleeve installation clamping device of the utility model can clamp the stator insulation sleeve at three points on the stator insulation sleeve installation disk to prevent the disk from falling apart during installation, and no electrical equipment is required. The mechanical elastic clamping saves power resources, and the key component spring 13 is easy to replace and easy to repair. First, the three groups of L-shaped clamps 6 are pulled outward. At this time, the three groups of L-shaped clamps 6 all slide along the inner wall of the slide groove 5 toward the edge of the chassis 1. At this time, the spring 13 is compressed and shortened, and the insulation sleeve disk 4 is sleeved on the outside of the fixing bolt 2 through the ring 3 on its inner wall and placed on the top of the chassis 1. At this time, the three groups of L-shaped clamps 6 are released, and the rebound force of the spring 13 causes the L-shaped clamps 6 to slide along the inner wall of the slide groove 5 toward the center of the chassis 1. The L-shaped clamp 6 is made to press against the edge of the outer wall of the insulating sleeve 4 through the smooth layer 7 of its inner wall, and the top of the L-shaped clamp 6 is pressed against the top edge of the insulating sleeve 4, which effectively prevents the insulating sleeve 4 from falling apart. As the insulating sleeve 4 is pulled out by the stator insulating sleeve installation equipment, the diameter of the insulating sleeve 4 gradually decreases, and the compressed spring 13 continuously rebounds to ensure that the L-shaped clamp 6 is always firmly clamped. The smooth sleeve layer of the inner wall of the L-shaped clamp 6 reduces the friction coefficient, which can ensure that the L-shaped clamp 6 stably clamps the insulating sleeve 4, and the wound insulating sleeve can be smoothly pulled out and installed by the installation equipment. When the spring 13 needs to be replaced, the plugs 12 at both ends of the spring 13 are slid out of the plug sleeve 11 to install a new one.
