[0001] The utility model relates to the technical field of motor manufacturing, in particular to an adjustable fixture for iron core assembly. Background Art

[0002] The servo motor transmits the position information of the motor to the controller through a feedback device (such as an encoder), and the controller drives the motor to rotate according to the position error signal to eliminate the error. In this way, high-precision control of parameters such as the position, speed, and acceleration of the motor can be achieved, which can meet some specific application requirements, such as in the fields of robots, automation equipment, medical equipment, aerospace equipment, etc. During the assembly process of the servo motor, it is usually necessary to perform a press-fitting process on the iron core and the motor housing. The purpose of this step is to ensure a firm and stable connection between the iron core and the motor housing, so as to achieve good mechanical transmission and heat conduction.

[0003] After retrieval, in the prior art, Chinese Patent Application No.: CN201821326853.4 discloses an assembly positioning tooling for a motor stator core. This utility model realizes the purpose of ensuring the concentricity between the motor stator core and the rotor through the cooperation between the positioning fixture and the middle tube of the housing, and positions the motor stator core by setting spring ejector pins in the installation screw holes, effectively ensuring the assembly quality of the motor stator core.

[0004] However, this device still has the following defects: The applicant believes that when the press-fitting process is performed on the iron core and the motor housing, the iron core is prone to shift under force, resulting in difficulty in aligning the iron core with the motor housing, thereby affecting the assembly quality of the iron core; at the same time, the processing efficiency is low, making it difficult to meet the production requirements of industrialization.

[0005] Therefore, those skilled in the art provide an adjustable fixture for iron core assembly to solve the problems mentioned in the above prior art. Summary of the Utility Model

[0006] In order to solve the above problems, the utility model provides an adjustable fixture for iron core assembly.

[0007] The utility model is realized through the following technical solutions:

[0008] An adjustable fixture for iron core assembly, comprising an operating table. A clamping mechanism and a rotating mechanism are arranged on the front of the top of the operating table. The clamping mechanism includes a box body arranged on the top of the rotating mechanism. Central parts of the top of the box body are fixedly connected by bolts with limiting blocks. Clamping blocks are arranged on both sides of the limiting blocks. The bottoms of the clamping blocks are slidably connected with sliding sleeves. Springs are connected between the sliding sleeves and the clamping blocks. Both sides of the top of the box body are open. The sliding sleeves penetrate through the openings and extend into the inner cavity of the box body. Moving components are arranged at the bottoms of the sliding sleeves. An installation plate is fixedly connected by bolts to the back of the top of the operating table. A lifting plate is arranged on the front of the installation plate. A pressing block is fixedly connected by bolts to the bottom of the lifting plate. A lifting mechanism is arranged on the back of the lifting plate.

[0009] Preferably, the moving component includes a first motor fixedly assembled on one side of the box body. Output shafts of the first motor are fixedly connected by couplings with first lead screws. One sides of the first lead screws penetrate through the box body and are rotationally connected by bearings to the inner wall of the inner cavity of the box body. Moving blocks are threadedly connected to both sides of the surface of the first lead screw. The moving blocks are fixedly connected by bolts to the bottoms of the sliding sleeves.

[0010] Preferably, the bottoms of the moving blocks are fixedly connected by bolts with first sliders. Slide bars are slidably connected to the inner cavities of the first sliders. The slide bars are fixedly connected by bolts to the inner wall of the inner cavity of the box body.

[0011] Preferably, the rotating mechanism includes a second motor fixedly assembled on the bottom of the operating table. The output shaft of the second motor is fixedly connected by a coupling with a rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model uses the structural design of the clamping block, the sliding sleeve and the spring to limit the iron core through the clamping block, thereby avoiding the problem of the iron core being easily offset when subjected to force. When the iron core and the motor housing are pressed into a sleeve, the movement of the motor housing will push the clamping block into the inner cavity of the sliding sleeve, thereby ensuring that the clamping block will not interfere during the pressing process; through the structural design of the first motor, the first screw rod and the moving block, the position of the clamping block can be easily adjusted, so that the clamping block can be close to the two sides of the iron core, thereby improving the limiting effect of the iron core, and the adjustment is convenient, which helps to improve the practicality of the device.

[0017] 2. The utility model adopts the structural design of the second motor and the rotating disk. The second motor drives the rotating disk to rotate, thereby driving multiple groups of limit blocks to move. After the iron core and the motor shell on one group of limit blocks are pressed together, they can be turned out through the rotating disk and convenient for users to unload materials. At the same time, the iron core and the motor shell on the other group of limit blocks will rotate to the bottom of the pressing block and be pressed together. Therefore, loading and unloading can be carried out at the same time, which can save a lot of time. Brief Description of the Figures

[0025] Please refer to Figures 1 to 5 , the embodiments provided by the present utility model:

[0026] An adjustable fixture for iron core assembly is disclosed in an embodiment of the present application, including an operating table 1. A clamping mechanism and a rotating mechanism are arranged on the front of the top of the operating table 1. The clamping mechanism includes a box body 2 arranged on the top of the rotating mechanism. Central parts on the top of the box body 2 are fixedly connected by bolts with limiting blocks 3. Clamping blocks 4 are arranged on both sides of the limiting blocks 3. Sliding sleeves 5 are slidably connected to the bottoms of the clamping blocks 4. Springs 6 are used to connect between the sliding sleeves 5 and the clamping blocks 4. Both sides on the top of the box body 2 are open. The sliding sleeves 5 penetrate through the openings and extend into the inner cavity of the box body 2. Moving components are arranged at the bottoms of the sliding sleeves 5. An installation plate 7 is fixedly connected by bolts to the back of the top of the operating table 1. A lifting plate 8 is arranged on the front of the installation plate 7. A pressing block 9 is fixedly connected by bolts to the bottom of the lifting plate 8. A lifting mechanism is arranged on the back of the lifting plate 8.

[0027] As a technical optimization scheme of the present utility model, when the iron core is sleeved on the surface of the limiting block 3, the edge of the iron core will be located inside the limiting block 3 and the clamping block 4. At this time, clamping and limiting of the iron core can be realized, thereby overcoming the problem that the iron core is prone to shift when the iron core and the motor housing are subjected to a press-fitting process in the prior art, which leads to difficulty in aligning the iron core and the motor housing, and can effectively improve the quality of iron core assembly.

[0028] The moving component includes a first motor 10 fixedly assembled on one side of the box body 2. Output shafts of the first motor 10 are fixedly connected by couplings with first lead screws 11. One sides of the first lead screws 11 penetrate through the box body 2 and are rotatably connected by bearings to the inner wall of the inner cavity of the box body 2. Moving blocks 12 are threadedly connected to both sides of the surface of the first lead screw 11. The moving blocks 12 are fixedly connected by bolts to the bottoms of the sliding sleeves 5.

[0029] As a technical optimization scheme of the present utility model, the first lead screw 11 is a positive and negative lead screw, and internal threads matching with the first lead screw 11 are provided in the inner cavities of the moving blocks 12. Therefore, when the first lead screw 11 rotates, it can drive the two moving blocks 12 to move, and further can adjust the distance between the two clamping blocks 4, thereby enabling the clamping blocks 4 to approach the iron core and improving the limiting effect on the iron core.

[0030] The bottom of the moving block 12 is fixedly connected by bolts with the first slider 13. A slide bar 14 is slidably connected to the inner cavity of each first slider 13, and the slide bars 14 are fixedly connected by bolts to the inner wall of the inner cavity of the box body 2.

[0031] As a technical optimization scheme of the present utility model, the cooperation of the first slider 13 and the slide bar 14 plays a limiting role on the moving block 12, enabling it to move stably.

[0032] The rotating mechanism includes a second motor 15 fixedly assembled at the bottom of the operating table 1. The output shaft of the second motor 15 is fixedly connected by a coupling with a rotating shaft. The top of the rotating shaft penetrates through the operating table 1 and is fixedly connected by bolts with a rotating disk 16, and the rotating disk 16 is fixedly connected by bolts to the bottom of the box body 2.

[0033] As a technical optimization scheme of the present utility model, the second motor 15 can drive the rotating shaft and the rotating disk 16 to rotate, so that the limiting block 3 rotates in sequence and is located at the bottom of the pressing block 9, thereby realizing the synchronous progress of loading and unloading, and effectively improving the processing efficiency.

[0034] The lifting mechanism includes a third motor 17 fixedly assembled at the top of the operating table 1. The output shaft of the third motor 17 is fixedly connected by a coupling with a second lead screw 18. A movable block 19 is threadedly connected to the surface of the second lead screw 18. The front of the movable block 19 penetrates through the mounting plate 7 and is fixedly connected by bolts to the back of the lifting plate 8.

[0035] As a technical optimization scheme of the present utility model, an internal thread matching with the second lead screw 18 is provided in the inner cavity of the movable block 19. Therefore, when the second lead screw 18 rotates, it can drive the movable block 19 and the lifting plate 8 to move, thereby driving the pressing block 9 to press the motor housing, and thus performing a pressing sleeve treatment on the battery cell and the motor housing.

[0036] Both sides of the back of the lifting plate 8 are fixedly connected by bolts with second sliders 20. Both sides of the front of the mounting plate 7 are provided with chutes 21 matching with the second sliders 20.

[0037] As a technical optimization scheme of the present utility model, the cooperation of the second sliders 20 and the chutes 21 plays a supporting role on the lifting plate 8, thereby increasing its stability during lifting.

[0038] Both sides of the limiting block 3 are arc-shaped.

[0039] As a technical optimization scheme of the present utility model, it can make the limiting block 3 fit more closely with the iron core, and further improve the limiting of the iron core.

[0040] Working principle: The user sleevs the iron core on the surface of the limit block 3, and then can drive the first lead screw 11 to rotate through the first motor 10, so that the moving block 12 drives the clamping block 4 to move towards the iron core, thereby realizing the limitation of the iron core and making it not easy to shift. Then the user sleevs the motor housing on the top of the iron core and drives the second lead screw 18 to rotate through the third motor 17, so that the movable block 19 drives the lifting plate 8 and the pressing block 9 to move and press the motor housing, and then performs the pressing and sleeving treatment on the iron core and the motor housing. When the pressing and sleeving treatment is completed, the user can drive the rotating disk 16 to rotate through the second motor 15, so as to unload the processed iron core. At the same time, the next group of iron cores and motor housings sleeved on the limit block 3 will rotate to the bottom of the pressing block 9 for pressing and sleeving treatment. Thus, the synchronous feeding and unloading can be realized, the processing efficiency can be effectively improved, and the industrial production requirements can be met.
