Description

Technical Field

[0001] The present application relates to the technical field of generator magnetic pole processing, and in particular to a fixture for a machine tool for processing the outer circle of a generator magnetic pole. Background Art

[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. A circular hole is opened in the center of the mounting plate.

[0003] Now it is necessary to use a horizontal machine tool to process the outer circle of the generator pole. The horizontal machine tool usually fixes the workpiece through a three-jaw chuck, and then the three-jaw chuck rotates to process the edge of the workpiece through the tool. However, due to the distribution of the seven legs, the jaws of the traditional three-jaw chuck cannot simultaneously clamp against the legs or the mounting plate after moving the same stroke. In other words, the traditional three-jaw chuck cannot limit the generator pole and cannot process the outer circle of the generator pole. Summary of the Invention

[0004] An embodiment of the present application provides a fixture for a generator pole outer cylindrical machining machine tool to solve the problem in the related art that a traditional three-jaw chuck cannot clamp the generator pole.

[0005] In a first aspect, a fixture for a generator magnetic pole outer circle machining machine tool is provided, comprising:

[0006] Mounting rack;

[0007] A fixing plate connected to the center of the mounting frame, wherein the fixing plate has limited space for mounting the mounting plate and seven supporting legs;

[0008] A rotation limiting member, the rotation limiting member is provided on the fixing plate, and the rotation limiting member can be simultaneously attached to two adjacent legs;

[0009] A plurality of position limiting members are arranged circumferentially around the center of the fixing plate. The position limiting members include an opening plate, which is slidably connected to the fixing plate and can be tightly attached to the inner wall of the circular hole of the mounting plate.

[0010] In some embodiments, a synchronizing member is provided on the side of the fixed plate, and the synchronizing member is rotatably connected to the fixed plate. When the synchronizing member rotates on the fixed plate, the plurality of opening plates move simultaneously.

[0011] In some embodiments, the position limiting member further includes a screw;

[0012] The screw rod is rotatably connected to the fixed plate, passes through the opening plate, and is threadedly connected to the opening plate.

[0013] In some embodiments, a driving member is provided at one end of the screw rod away from the center of the fixing plate, and the driving member is connected to the screw rod.

[0014] Some embodiments further include a plurality of support platforms;

[0015] A plurality of support platforms are arranged along the edge of the fixing plate.

[0016] Some embodiments further include a mounting platform;

[0017] The mounting platform is connected to the rotation limiting member, and the mounting platform is connected to the supporting platform.

[0018] An embodiment of the present application provides a fixture for a machine tool for processing the outer circle of a generator pole. Since the present application rotatably connects a fixed plate equipped with a rotation limiting part and a position limiting part to a mounting frame, when the generator pole is installed, multiple open plates are simultaneously pressed against the inner wall of the circular hole of the mounting plate to limit the position of the generator pole. At the same time, the rotation limiting part is pressed against the side of the support foot, so that the generator pole cannot rotate. At this time, the generator pole is fixed on the fixed plate and cannot rotate. Therefore, by rotating the fixed plate, the generator pole fixed thereon is rotated for processing.

[0025] 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.

[0026] An embodiment of the present application provides a fixture for a generator pole outer circle machining machine tool, which can solve the problem in the related art that a traditional three-jaw chuck cannot clamp the generator pole.

[0027] See also Figures 1 to 4 , a fixture for a generator magnetic pole outer circle machining machine tool, comprising:

[0028] Mounting frame 1;

[0029] A fixing plate 2, which is connected to the center of the mounting frame 1 and has limited space for mounting a mounting plate and seven legs;

[0030] A rotation limiting member 3 is provided on the fixing plate 2, and the rotation limiting member 3 can be attached to two adjacent legs at the same time;

[0031] a plurality of position limiting members 4, the plurality of position limiting members 4 being circumferentially arranged around the center of the fixing plate 2, the position limiting members 4 including an opening plate 41, the opening plate 41 being slidably connected to the fixing plate 2, the opening plate 41 being able to cling to the inner wall of the circular hole of the mounting plate;

[0032] The mounting frame 1 is part of the horizontal machine tool. The fixed plate 2 is a circular plate. The fixed plate 2 and the mounting frame 1 are fixed by countersunk screws. Therefore, the fixed plate 2 can be rotated by rotating the mounting frame 1. A rotation limiter 3 and four position limiters 4 are respectively provided on the fixed plate 2. The rotation limiters 3 and the position limiters 4 fix the generator poles to the fixed plate 2, so that the fixed plate 2 rotates and drives the generator poles to rotate for processing;

[0033] The rotation limiting member 3 and the four position limiting members 4 on the fixing plate 2 are all arranged around the center of the fixing plate 2, such as Figure 3 As shown;

[0034] The process of installing the generator pole on the fixed plate 2 is as follows: first, the open plate 41 is passed through the circular hole of the mounting plate. At this time, the generator pole is hung on the open plate 41. Then, the position of the open plate 41 is moved so that the four open plates 41 are away from the center of the fixed plate 2. Finally, the outer sides of the four open plates 41 are close to the position of the circular hole of the mounting plate to fix the position of the generator pole on the fixed plate 2. At the same time, the rotation limiter 3 will be close to the side walls of any two adjacent legs, so that the generator pole will rotate with the fixed plate 2.

[0035] It should be noted that in this application, since the space between two adjacent legs is arc-shaped, the abutting surface of the rotation limiter 3 is also arc-shaped, and the movement strokes of the four open plates 41 that fix the generator pole position are the same.

[0036] The position limiting member 4 further includes a screw rod 42;

[0037] The screw rod 42 is rotatably connected to the fixed plate 2 , and the screw rod 42 passes through the opening plate 41 , and the screw rod 42 is threadedly connected to the opening plate 41 ;

[0038] A synchronous member 5 is provided on the side of the fixed plate 2, and the synchronous member 5 is rotatably connected to the fixed plate 2. When the synchronous member 5 rotates on the fixed plate 2, the plurality of opening plates 41 move simultaneously.

[0039] A driving member 43 is provided at one end of the screw rod 42 away from the center of the fixing plate 2 , and the driving member 43 is connected to the screw rod 42 ;

[0040] Four chute grooves are respectively provided on the fixed plate 2, and the positions of the four chute grooves correspond to the four opening plates 41 respectively. A slider is fixedly connected to the bottom of the opening plate 41, and the slider is slidably connected in the chute. The screw rod 42 is rotatably connected in the chute, and the length direction of the screw rod 41 is the same as the extension direction of the chute. The screw rod 42 passes through the slider, and the screw rod 42 is threadedly connected to the slider. The opening plate 41 is driven to slide on the fixed plate 2 by the rotation of the screw rod 42;

[0041] In a preferred embodiment, the driving member 43 is a bevel gear, and the synchronizer 5 is a bevel gear ring. The synchronizer 5 engages with the four driving members 43 at the same time. When the synchronizer 5 rotates, the four driving members 43 will rotate synchronously, and then the synchronizer 5 rotates and drives the four screw rods 42 to rotate at the same time, thereby realizing the movement of the four opening plates 41 by the synchronizer 5, so that the fixed position of the generator pole must be in the center of the fixed plate 2.

[0042] It also includes a plurality of support platforms 6, and the plurality of support platforms 6 are arranged along the edge of the fixed plate 2;

[0043] The generator poles are fixed on the fixed plate 2 by the rotation limiting member 3 and the position limiting member 4. Before processing, it is necessary to perform the tool setting operation first, and then design the program to edit the tool movement path based on the tool setting result. The function of the support platform 6 is to support the bottom of the mounting plate so that the position of the generator poles installed on the fixed plate 2 and the distance between the fixed plate 2 are the same each time, so that the path of movement of the tool is also the same each time it is processed. There is no need to repeat the tool setting and other operations each time the generator poles are processed, thereby improving production efficiency.

[0044] It also includes a mounting platform 7, the mounting platform 7 is connected to the rotation limiting member 3, and the mounting platform 7 is connected to the support platform 6;

[0045] The mounting platform 7 is welded to the rotation limiting member 3 , and the mounting platform 7 is connected to the supporting platform 6 by bolts.
