[0002] Generator poles such as Figure 1 As shown, the generator pole mainly includes a mounting plate and 7 legs. The 7 legs are distributed around the edge of the mounting plate. The arc length covered by each leg is the same as the arc length between every two legs.

[0003] It is now necessary to drill a hole in the center of the mounting plate. The commonly used drilling method is to fix the workpiece with the three jaws of a three-jaw chuck and then perform processing with a rotating drill bit. However, the two jaws of a traditional three-jaw chuck are 120 degrees apart, and the contact surface between the traditional jaws and the workpiece is small. As a result, after moving the same stroke, the three jaws of the traditional three-jaw chuck cannot all be clamped on the edge of the bracket or the edge of the mounting plate at the same time, making it impossible to clamp the generator poles using the traditional three-jaw chuck. Summary of the Invention

[0004] An embodiment of the present application provides a generator magnetic pole end face drilling device to solve the problem in the related art that traditional clamping jaws cannot clamp the generator magnetic poles.

[0005] In a first aspect, a generator magnetic pole end face drilling device is provided, comprising:

[0006] A chuck, wherein there is a space in the middle of the chuck for placing the mounting plate and a plurality of supporting legs;

[0007] Three clamping jaws, the three clamping jaws are circumferentially arranged around the edge of the chuck and slidably connected to the chuck, the clamping jaws including a clamping end, the side of the clamping end facing the center of the chuck being arc-shaped, and the arc-shaped side of the clamping end can be closely attached to the placement space;

[0008] When the clamping end is in close contact with the placement space, the arcuate side of the clamping end is in close contact with at least one of the supporting legs.

[0009] In some embodiments, the claw further includes a connecting end and a moving end;

[0010] The movable end is slidably connected to the chuck, and both sides of the connecting end are respectively connected to the clamping end and the movable end.

[0011] In some embodiments, an insert block is provided on a side of the connecting end connected to the moving end, and a slot is provided on a side of the moving block connected to the connecting end, and the insert block can be inserted into the slot.

[0012] In some embodiments, the chuck is provided with a plurality of support rods;

[0013] The support rod includes a support portion, and the support portion can be closely attached to a side of the mounting plate facing the chuck.

[0014] In some embodiments, the number of the support rods is at least three, and the support rods are circumferentially arranged around the center point of the placement space.

[0015] In some embodiments, the support rod further includes a bottom shaft;

[0016] The bottom shaft is connected to the chuck, and the supporting portion is plugged into the bottom shaft.

[0017] In some embodiments, the center of one side of the chuck provided with the clamping claw is recessed toward the opposite side to form a groove, and the bottom of the groove is flat.

[0018] An embodiment of the present application provides a device for drilling a hole at the end face of a generator magnetic pole. Since the present application expands the coverage area of ​​the arc-shaped side of the clamping end by designing the clamping end, the arc-shaped side of the clamping end will inevitably be close to one of the legs after the three claws move the same stroke, so that the three clamping ends can fix the generator magnetic pole in the center of the three claws. Therefore, the present application can achieve clamping of the generator magnetic pole while changing the coverage area of ​​the clamping end according to the structure of the generator magnetic pole.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] An embodiment of the present application provides a generator magnetic pole end face drilling device, which can solve the problem in the related art that traditional clamping claws cannot clamp the generator magnetic poles.

[0028] See also Figures 1 to 5 , a generator magnetic pole end face drilling device, comprising:

[0029] A chuck 1, wherein there is a space in the middle of the chuck 1 for placing the mounting plate and a plurality of legs;

[0030] Three clamping jaws 2, the three clamping jaws 2 are circumferentially arranged around the edge of the chuck 1, and the clamping jaws 2 are slidably connected to the chuck 1, and the clamping jaws 2 include a clamping end 21, and the side of the clamping end 21 facing the center of the chuck 1 is arc-shaped, and the arc-shaped side of the clamping end 21 can be closely attached to the placement space;

[0031] When the clamping end 21 is in close contact with the placement space, the arcuate side of the clamping end 21 is in close contact with at least one of the legs;

[0032] In this embodiment, if Figure 1 As shown, the chuck 1 is a cylinder, and the three jaws 2 are all arranged on the upper end surface of the chuck 1. In a preferred embodiment, the clamping end 21 is an arc-shaped plate, and the arc length of the arc side of the clamping end 21 is at least the sum of the arc lengths of the two legs. In this way, no matter how the generator pole is placed in the center of the chuck, the arc side of the clamping end 21 will eventually stick to one of the legs during clamping, thereby achieving the three clamping ends 21 clamping the generator pole at the same time.

[0033] The claw 2 also includes a connecting end 22 and a moving end 23;

[0034] The movable end 23 is slidably connected to the chuck 1 , and both sides of the connecting end 22 are respectively connected to the clamping end 21 and the movable end 23 ;

[0035] An insert block 3 is provided on the side of the connecting end 22 connected to the moving end 23 , and a slot 4 is provided on the side of the moving block connected to the connecting end 22 , and the insert block 3 can be inserted into the slot 4 ;

[0036] The connecting end 22 is welded to the clamping end 21. The insert 3 and the slot 4 are T-shaped structures. The slot 4 is opened from the upper end surface to the lower end surface of the movable end 23, and the slot 4 does not pass through the lower end surface of the movable end 23. Therefore, when installing the connecting end 22 and the clamping end 21, it is only necessary to insert the insert 3 into the slot 4 from top to bottom.

[0037] It should be noted that if it is necessary to drill holes for generator poles of different sizes, the clamping ends 21 of different sizes can be selected according to the size of the generator poles and installed on the moving end 23 through the connecting end 22;

[0038] In this application, the driving mode of the mobile terminal 23 is the driving mode of the traditional three-jaw chuck, such as Figure 3 As shown, the driving of the mobile terminal 23 is not described in detail here.

[0039] The chuck 1 is provided with a plurality of support rods 5;

[0040] The support rod 5 includes a support portion 51, and the support portion 51 can be closely attached to a side of the mounting plate facing the chuck 1;

[0041] The number of the support rods 5 is at least three, and the support rods 5 are arranged circumferentially around the center point of the placement space;

[0042] The center of one side of the chuck 1 provided with the clamping jaw 2 is recessed toward the opposite side to form a groove, and the bottom of the groove is flat;

[0043] Since the generator magnetic poles need to be drilled through holes, if the legs are used as supports for the generator magnetic poles on the surface of the chuck 1, they need to support the mounting plate when drilling. Since the legs are thin, they are easily damaged. If the mounting plate is placed directly against the chuck 1, the chuck 1 may be directly penetrated during drilling. Therefore, the present application provides support rods 5 in the groove of the chuck 1. Multiple support rods 5 support the mounting plate from different places to avoid the problem of penetrating the chuck 1. At the same time, since the support rods 5 raise the generator magnetic poles, in order to allow the jaws 2 to continue to clamp, the support rods 5 are provided in the groove of the chuck 1.

[0044] In the present application, there are three support parts 51 , which are circumferentially distributed at the bottom of the mounting plate. The three support parts 51 respectively support different positions of the bottom of the mounting plate to prevent the mounting plate from tilting during drilling.

[0045] The support rod 5 further includes a bottom shaft 52;

[0046] The bottom shaft 52 is connected to the chuck 1 , and the support portion 51 is plugged into the bottom shaft 52 ;

[0047] like Figure 4 As well as Figure 5 As shown, a circular hole is provided at the top of the bottom shaft 52, and a cylinder is provided at the bottom of the support part 51. The support part 51 is installed on the bottom shaft 52 by inserting the cylinder into the circular hole. At the same time, the support part 51 can be quickly installed and disassembled on the bottom shaft 52, and the subsequent maintenance and replacement of the support part 51 is convenient while ensuring the strength of the support part 51 and the bottom shaft 52.

[0048] Here's how this application works:

[0049] Before using this application, it is necessary to first install the support part 51 on the bottom shaft 52, then select different sizes of clamping ends 21 according to different sizes of generator poles, and then install the clamping end 21 on the moving end 23 through the connecting end 22;

[0050] When in use, the generator pole is first placed in the groove of the chuck 1, and the generator pole is supported by the support portion 51, and then the clamping end 21 is driven by the moving end 23 to clamp the generator pole.
