The second end of the locking block is connected to the housing shaft. A groove for accommodating the first locking plate is provided on the side of the locking block facing the locking pin.

[0007] As a further description of the above technical solution, the locking mechanism has a first station and a second station. In the first station, the first locking piece and the second locking piece are flush with the first end face, the limiting block rotates to the first end of the mounting groove, and the iron core is limited in the mounting groove by the floating seat and the limiting block. In the second station, the first locking piece retracts into the groove, and the limiting block disengages from the first end of the mounting groove.

[0008] As a further description of the above technical solution, the lock block is provided with a counterweight on one side of the second end of the groove, so that when the locking mechanism is in the second working position, the groove of the lock block is in close contact with the first lock piece in the direction of the lock post.

[0009] As a further description of the above technical solution, the locking pin consists of two independent sections connected by a spring.

[0021] Please see Figure 1-3 This embodiment provides a segmented motor clamp for clamping an iron core 100, wherein the segmented motor clamp includes: The housing 1 has a first end and a second end arranged opposite to each other along the axial direction. The housing 1 has a mounting groove 11 on the outer side wall between the first end and the second end. The mounting groove 11 is used to place the iron core 100. An opening 12 is provided at the second end of the mounting groove 11. A floating mechanism 2 is installed inside the housing 1. The floating mechanism 2 includes an elastic element 21 and a floating seat 22. The first end of the elastic element 21 is connected to the floating seat 22, and the second end of the elastic element 21 is connected to the bottom of the housing 1. At least a portion of the floating seat 22 passes through the opening 12. The first end face of the floating seat 22 is used to provide floating support for the second end of the iron core 100. The locking mechanism 3 includes a locking pin 31 and a locking block 32. The locking pin 31 is axially inserted into the housing 1. The first end of the locking pin 31 is connected to a first locking piece 311 that protrudes radially outward from the locking pin 31. The first end of the locking block 32 is connected to a second locking piece 321 that cooperates with the first locking piece 311, and a limiting block 322 facing the first end of the mounting groove 11. The second end of the locking block 32 is connected to the rotating shaft of the housing 1. The locking block 32 has a groove 323 on the side facing the locking pin 31 for accommodating the first locking piece 311.

[0022] Specifically, based on the above structure, the locking mechanism 3 has a first working position and a second working position. In the first working position, the first locking piece 311 and the second locking piece 321 are flush with the first end face, the limiting block 322 rotates to the first end of the mounting groove 11, and the iron core 100 is limited in the mounting groove 11 by the floating seat 22 and the limiting block 322. In the second working position, the first locking piece 311 retracts into the groove 323, and the limiting block 322 disengages from the first end of the mounting groove 11.

[0023] In the specific use of this embodiment, the locking pin 31 of the locking mechanism 3 is first pulled towards the second end at the bottom, so that the first locking plate 311 and the second locking plate 321 are misaligned. The first locking plate 311 and the second locking plate 321 do not have a mutual support relationship. Therefore, the locking block 32 can rotate without restriction. The second locking plate 321 of the locking block 32 can move the limiting block 322 used to limit the first end of the iron core 100 out of the mounting groove 11 under the rotation of the locking block 32. At this time, it is the state of the second working position. Under this situation, the operator can take out the iron core 100 in the mounting groove 11 or put in a new iron core 100. After placing the new iron core 100, operate the locking pin 31 of the locking mechanism 3 in the opposite direction and pull it towards the first end at the top, so that the first locking plate 311 and the second locking plate 321 are flush and have a mutual supporting relationship. At this time, the limiting block 322 at the other end of the second locking plate 321 extends into the mounting groove 11 to limit the top of the iron core 100.

[0024] When installing iron cores 100 at different heights, the floating seat 22 can move up and down along the axial direction under the drive of the elastic element 21, always matching the bottom position of the iron core 100.

[0025] In other words, based on the structure of this embodiment, the floating mechanism 2 can be used for iron cores 100 with various height differences, and quick release can be achieved through the locking mechanism 3, which helps to improve the efficiency of the fixture. Specifically, the floating seat 22 in the floating mechanism 2 is located at the second end of the bottom of the mounting groove 11 for mounting the iron core 100. The elastic member 21 on one side of the floating seat 21 provides elastic contact with the iron core 100. For iron cores 100 of different heights, the floating match can be achieved by the extension and retraction of the bottom elastic member 21, thus obtaining a wider range of applications. At the same time, quick release can be achieved by pulling the locking pin 31 up and down along the axial direction in the locking mechanism 3, which facilitates the rapid installation of the iron core 100 and has the characteristics of high efficiency, speed, and wide applicability.

[0026] In another embodiment, the locking block 32 is provided with a counterweight 324 on one side of the second end of the groove 323, so that when the locking mechanism 3 is in the second working position, the groove 323 of the locking block 32 is in close contact with the first locking piece 311 in the direction facing the locking post 31. The counterweight 324 allows the locking block 32 to have a tendency to reset as soon as the first locking piece 311 disengages from the second locking piece 321, tilting axially so that the limiting block 322 can quickly disengage from the top of the mounting groove 11 without manual intervention.

[0027] Furthermore, the locking pin 31 consists of two independent sections connected by a spring 312. When the spring 312 is relaxed, the locking mechanism 3 is in the first position; when the spring 312 is compressed, the locking mechanism 3 is in the second position. Therefore, the operator can switch between the two positions by pressing the first locking piece 311 at the top of the first end. Without manual intervention, the locking mechanism 3 is always in the second position, ensuring that the iron core 100 is difficult to disengage, preventing accidents, and providing high safety.

[0028] In this embodiment, there are multiple grooves 323, which are spaced axially on the outer wall of the housing 1. The floating mechanism 2 and the locking mechanism 3 correspond one-to-one with the multiple grooves 323. Specifically, there are four grooves 323, and the first locking piece 311 of the locking pin 31 is cross-shaped. That is to say, the fixture can produce four iron cores 100, and pressing or pulling the locking pin 31 can simultaneously perform pick-and-place operations on the four iron cores 100.

[0029] Furthermore, a movable pin 23 is connected to the first end of the floating seat 22, and a movable groove 13 is provided inside the housing 1 for the movable pin 23 to be inserted axially. When the floating seat 22 moves up and down axially, the movable pin 23 passes through the movable groove 13 and moves relative to the movable groove 13, which can ensure that the floating seat 22 always moves axially and avoids the support of the iron core 100 shifting.

[0030] Furthermore, the first end of the housing 1 is provided with an axially extending pin 14 for winding, which can be used to fix the position of the wire and facilitate winding of the iron core 100.

Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
