Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet assembly, in particular to a permanent magnet automatic assembly device with self-positioning. Background Art

[0002] A permanent magnet refers to a magnet that can retain a relatively high residual magnetism for a long time in an open-circuit state, also known as a hard magnet. Its characteristics are that it is not easy to lose magnetism and is not easy to be magnetized. Permanent magnets include natural magnets (such as magnetite) and artificial magnets (such as alnico alloys, neodymium iron boron, etc.). These materials are widely used in many fields such as electric motors, generators, speakers, and medical equipment. However, if the permanent magnet is heated above the Curie temperature or placed in a reverse high magnetic field, its magnetism may decrease or disappear. In addition, some permanent magnets may be brittle at high temperatures and are prone to cracking.

[0003] In the current prior art, a circular shell is placed above a support frame. During the installation of the permanent magnet, the shell needs to rotate at intervals, and during the rotation of the shell, the permanent magnet is installed one by one between the inner walls of the circular shell by a feeding device of the permanent magnet to achieve automatic installation of the permanent magnet. When the diameter of the circular outer shell changes, the relative height of the circular shell placed above the support frame will change, and the position of the inside of the circular shell and the feeding position of the permanent magnet will shift, and at this time, the assembly of the permanent magnet cannot be carried out.

[0004] Therefore, in view of the above problems, a permanent magnet automatic assembly device with self-positioning is proposed. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problem that when the diameter of the circular outer shell changes, the relative height of the circular shell placed above the support frame will change, and the position of the inside of the circular shell and the feeding position of the permanent magnet will shift, and at this time, the assembly of the permanent magnet cannot be carried out, a permanent magnet automatic assembly device with self-positioning is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is: A permanent magnet automatic assembly device with self-positioning according to the utility model includes two symmetrically installed support vertical plates. Arc-shaped openings are provided below the side walls of both support vertical plates. A semi-circular opening is provided on the side wall of one of the support vertical plates, and the semi-circular opening is located outside the arc-shaped opening. A side wall track is provided below the side wall of the other support vertical plate. Two support rollers are installed between the two support vertical plates. Installation shafts are clamped at both ends of the shafts of the two support rollers. The two installation shafts are respectively slidably installed inside the two arc-shaped openings. Annular grooves are provided on the outer walls of one ends of the two installation shafts. A position control component is installed on the side wall of one of the support vertical plates.

[0007] Preferably, the position control component includes a bidirectional lead screw. Both ends of the bidirectional lead screw are fixedly connected with lead screw brackets through bearings, and the lead screw brackets are fixedly connected to the side wall of the supporting vertical plate.

[0008] Preferably, threaded sleeves are installed on the external threads at both ends of the bidirectional lead screw. Fixedly connected to the top of both threaded sleeves are telescopic vertical plates, and one ends of the two telescopic vertical plates are respectively clamped inside the two annular grooves.

[0009] Preferably, auxiliary sliders are fixedly connected to the side walls of both threaded sleeves, and both auxiliary sliders are slidably installed inside the side wall tracks.

[0010] Preferably, a first motor is installed on the side wall of one of the supporting vertical plates through a bracket, and the output shaft of the first motor is connected to the axis of the bidirectional lead screw.

[0011] Preferably, a second motor is installed on the side of one of the mounting shafts through a bracket, and the output shaft of the second motor is connected to the axis of one of the supporting rollers.

[0012] Preferably, an electric telescopic rod is installed on the top of one of the supporting vertical plates, and a pressing plate is fixedly connected to one end of the electric telescopic rod.

[0013] Preferably, pressing rollers are symmetrically installed on the bottom of the pressing plate through brackets.

[0014] Advantages of the present utility model:

[0015] 1. In the present utility model, the linkage between the supporting vertical plate and the supporting rollers is realized through the mutual cooperation between the arc-shaped openings on the two supporting vertical plates and the mounting shafts installed at both ends of the two supporting rollers. The supporting rollers can cooperate with each other to form straight grooves on the lower part of the outer wall of the circular shell, and the position control component is linked with the mounting shaft. This enables the relative distance between the two supporting rollers to be adjusted during the rotation of the position control component. While ensuring the supporting effect on the circular shell, when the diameter of the circular shell changes within a certain range, the supporting rollers can ensure that the relative positions of their axes remain unchanged, enhancing the adaptability of the device.

[0016] 2. In the present utility model, the second motor provides a rotational output force for one of the supporting rollers, enabling the circular outer shell placed thereon to rotate accordingly. The pressing rollers can provide a certain downward pressure on it without interfering with its rotation, thereby enhancing the rotational stability of the circular outer shell and improving the structural rationality of the device.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The following gives specific embodiments.

[0027] Please refer to Figure 1 - Figure 5, the present utility model provides a permanent magnet automatic assembly device with self - positioning, including two symmetrically installed supporting vertical plates 1. Arc - shaped openings 11 are provided below the side walls of the two supporting vertical plates 1. A semi - circular opening 12 is provided on the side wall of one of the supporting vertical plates 1, and the semi - circular opening 12 is located outside the arc - shaped opening 11. A side - wall track 13 is provided below the side wall of the other supporting vertical plate 1. Two supporting rollers 2 are installed between the two supporting vertical plates 1. Mounting shafts 3 are clamped at both ends of the shafts of the two supporting rollers 2. The two sides of the mounting shafts 3 are respectively slidably installed inside the two arc - shaped openings 11. Annular grooves 31 are provided on the outer walls of one ends of the two mounting shafts 3. A position - control component 4 is installed on the side wall of one of the supporting vertical plates 1. Through the mutual engagement between the mounting shafts 3 clamped at both ends of the supporting roller 2 and the arc - shaped openings 11, the linkage between the supporting vertical plate 1 and the supporting roller 2 is realized. After the circular shell is placed above the supporting roller 2, its opening extends to the outside of the device through the semi - circular opening 12 and is docked with the feeding device of the permanent magnet. The position - control component 4 is installed on one side of the two mounting shafts 3 to adjust the relative distance and height of the two mounting shafts 3 within a certain range;

[0028] As Figure 1 , Figure 3 and Figure 4 shown, the position - control component 4 includes a bidirectional lead screw 41. Both ends of the bidirectional lead screw 41 are fixedly connected with lead - screw brackets 411 through bearings, and the lead - screw brackets 411 are fixedly connected to the side wall of the supporting vertical plate 1. Threaded sleeves 42 are installed on the external threads at both ends of the bidirectional lead screw 41. Telescopic vertical plates 421 are fixedly connected to the tops of the two threaded sleeves 42. One - end openings of the two telescopic vertical plates 421 are respectively clamped inside the two annular grooves 31. The bidirectional lead screw 41 is installed through the mutual cooperation between the lead - screw brackets 411 and the side wall of the supporting vertical plate 1. The threaded sleeves 42 installed on the external threads of the bidirectional lead screw 41 are linked with the mounting shafts 3 through the mutual clamping between the telescopic vertical plates 421 and the annular grooves 31. Thus, the device can adjust the relative height and distance of the two supporting rollers 2 within a certain range by rotating the bidirectional lead screw 41, adapt to the change in the size of the circular shell it supports, and ensure that the relative positions of the axes of different - sized circular shells remain unchanged after being supported;

[0029] As Figure 2 and Figure 4 shown, auxiliary sliders 422 are fixedly connected to the side walls of the two threaded sleeves 42. The two auxiliary sliders 422 are respectively slidably installed inside the side - wall track 13. Through the mutual fit between the threaded sleeves 42 and the side - wall track 13, the movement of the threaded sleeves 42 is not hindered while the structural stability of the threaded sleeves 42 is increased;

[0030] As Figure 4As shown, a first motor 5 is mounted on the side wall of one of the supporting vertical plates 1 through a bracket. The output shaft of the first motor 5 is connected to the axis of the bidirectional lead screw 41. The first motor 5 provides a rotational output force for the bidirectional lead screw 41, thereby controlling the relative position between the two supporting rollers 2.

[0031] As Figure 1 and Figure 3 As shown, on one side of one of the mounting shafts 3, a second motor 6 is mounted through a bracket. The output shaft of the second motor 6 is connected to the axis of one of the supporting rollers 2. The second motor 6 provides a rotational output force for the supporting roller 2, thereby controlling the relative rotation of the housing placed on the supporting roller 2.

[0032] As Figure 1 and Figure 5 As shown, an electric telescopic rod 7 is mounted on the top of one of the supporting vertical plates 1. One end of the electric telescopic rod 7 is fixedly connected to a pressing plate 8. Pressing rollers 9 are symmetrically mounted on the bottom of the pressing plate 8 through brackets. The pressing plate 8 is mounted above the supporting vertical plate 1 through the electric telescopic rod 7, so that the relative height of the pressing plate 8 can be controlled by the telescopic movement of the electric telescopic rod 7, thereby ensuring the downward pressing force of the pressing rollers 9 on the pressing plate 8 against the circular housing within a certain range. This downward pressing force can increase the structural stability during its rotation while not interfering with the rotation of the circular housing.

[0033] Working principle: The supporting roller 2 realizes the linkage between the supporting vertical plate 1 and the supporting roller 2 through the mutual engagement between the mounting shafts 3 clamped at both ends of the supporting roller 2 and the arc-shaped opening 11. After the circular housing is placed above the supporting roller 2, its opening extends to the outside of the device through the semi-circular opening 12 and is docked with the feeding device of the permanent magnet. The position control assembly 4 is mounted on one side of the two mounting shafts 3 to adjust the relative distance and height of the two mounting shafts 3 within a certain range. The bidirectional lead screw 41 is mounted through the mutual cooperation between the lead screw bracket 411 and the side wall of the supporting vertical plate 1. The thread sleeve 42 mounted on the thread of the bidirectional lead screw 41 is linked with the mounting shaft 3 through the mutual clamping between the telescopic vertical plate 421 and the annular groove 31. Thus, the device can adjust the relative height and distance of the two supporting rollers 2 within a certain range by rotating the bidirectional lead screw 41 to adapt to the change in the size of the circular housing it supports, ensuring that the relative positions of the axes of different-sized circular housings remain unchanged after being supported. The thread sleeve 42 fits with the side wall track 13 through the auxiliary slider 422. The first motor 5 provides a rotational output force for the bidirectional lead screw 41, and the second motor 6 provides a rotational output force for the supporting roller 2. The pressing plate 8 is mounted above the supporting vertical plate 1 through the electric telescopic rod 7, so that the relative height of the pressing plate 8 can be controlled by the telescopic movement of the electric telescopic rod 7, thereby ensuring the downward pressing force of the pressing rollers 9 on the pressing plate 8 against the circular housing within a certain range and increasing the structural stability during its rotation.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
