DETAILED DESCRIPTION

[0036] The following will be described in detail with reference to the accompanying drawings Figures 1-4 The application is further described in detail.

[0037] The embodiment of the application discloses a processing equipment for permanent magnets. Referring to Figure 1 The processing equipment for permanent magnets comprises a processing table 1 and a lifting table 2, the processing table 1 is provided with a working position cavity 11 with an upper opening, and a clamp 3 is mounted to the inner bottom wall of the working position cavity 11, so that the clamp 3 can clamp the permanent magnet. The lifting table 2 is arranged above the processing table 1, and the lifting table 2 is provided with a polishing mechanism 4, the polishing mechanism 4 comprises a motor, a transmission rod and a polishing disc 41, the motor is mounted to the lifting table 2, and the output end of the motor is arranged downward, the transmission rod vertically extends and is coaxially and fixedly connected to the output end of the motor at the upper end, and the lower end is fixedly connected with the polishing disc 41.

[0038] Referring to Figure 1 At the same time, the processing table 1 is fixedly provided with a drain pipe 12 which is communicated with the working position cavity 11. The processing table 1 is provided with a protective cover 5 above, and the protective cover 5 covers the working position cavity 11. In addition, a plurality of spray heads 7 are mounted to the inner wall of the protective cover 5.

[0039] In use, the permanent magnet is clamped to the clamp 3, then the lifting table 2 is operated and the motor is started at the same time, so that the lifting of the polishing disc 41 can be controlled to polish the permanent magnet. In the processing process, the protective cover 5 can protect the processing area, and reduce the possibility that the generated debris scatters to the outside of the working position cavity 11. After the processing is completed, the spray heads 7 are started to flush the permanent magnet and other components in the working position cavity 11, then the waste water is discharged from the drain pipe 12, so that the cleaning is relatively convenient, and the subsequent polishing processing of the permanent magnet is facilitated, and the use effect of the processing equipment is improved.

[0040] When the permanent magnet is taken out, the lifting table 2 is reset, the motor is turned off, and the protective cover 5 is started at the same time.

[0041] In order to facilitate the observation of the processing process, the side wall of the working position cavity 11 is transparent, for example, made of glass or transparent plastic.

[0042] Referring toFigure 1 The protective cover 5 is provided with a hot air pipe 6, one end of the hot air pipe 6 is communicated with the work station cavity 11, and in use, the other end of the hot air pipe 6 is only needed to be connected to the air outlet end of the drying machine. At the same time, the protective cover 5 is provided with a ventilation opening 51, and the work station cavity 11 is communicated with the outside through the ventilation opening 51, so as to facilitate the internal and external airflow circulation of the work station cavity 11.

[0043] In use, after the flushing in the work station cavity 11 is completed, hot air can be input into the work station cavity 11 through the hot air pipe 6, so as to dry the internal components and the permanent magnet of the work station cavity 11, and the cleaning effect is increased. Moreover, the ventilation opening 51 can increase the airflow circulation effect in the work station cavity 11, so that the drying effect is better.

[0044] Referring to Figure 1 and Figure 2 In use, in order to reduce the possibility that water splashes out from the ventilation opening 51 during flushing, the ventilation opening 51 is covered with a water blocking block 511, which is made of sponge or gauze and has the effects of blocking water and circulating air. A plurality of fixing rods 512 are arranged through the water blocking block 511, and at this time, the opening edge of the ventilation opening 51 is provided with a clamping strip 513, which is detachably connected to the protective cover 5 through bolts. The end portions of the fixing rods 512 are clamped between the clamping strip 513 and the opening edge of the ventilation opening 51.

[0045] In use, the water blocking block 511 can block the splashing water, and reduce the possibility that the water splashes out from the ventilation opening 51. At the same time, the water blocking block 511 does not easily block the airflow circulation during drying. At the same time, the water blocking block 511 is detachable relative to the protective cover 5 through the fixing rods 512, so that the installation and replacement of the water blocking block 511 are facilitated. In addition, the hot air stream during drying in the work station cavity 11 also has a drying effect on the water blocking block 511, so as to ensure the subsequent use effect of the water blocking block 511. At the same time, the fixing rods 512 can also support and reinforce the water blocking block 511 as a whole, so that the possibility that the water blocking effect of the water blocking block 511 is reduced due to deformation of the water blocking block 511 at the ventilation opening 51 is reduced.

[0046] Referring to Figure 1 and Figure 3 The lifting platform 2 is fixedly connected with a vertically extending mounting sleeve 21, and the mounting sleeve 21 is sleeved on the transmission rod, so that the lifting platform 2 can simultaneously control the lifting of the polishing mechanism 4 and the mounting sleeve 21. The protective cover 5 is provided with a mounting hole in the middle, and the protective cover 5 is sleeved and slidingly connected to the mounting sleeve 21, so that the mounting sleeve 21 is arranged in the mounting hole. The lower end of the mounting sleeve 21 is provided with a limiting portion.

[0047] In the processing, when the lifting platform 2 controls the polishing mechanism 4 and the mounting sleeve 21 to descend at the same time, the protective cover 5 will also descend under the action of its own gravity until it abuts against the processing platform 1 and covers the working cavity 11. Then, the polishing mechanism 4 is continuously controlled to descend, so that the polishing disc 41 can polish the permanent magnet. At this time, the protective cover 5 and the mounting sleeve 21 can relatively slide, reducing the possibility of limiting the polishing process. In addition, the limiting part can limit the sliding of the protective cover 5, reducing the possibility of the protective cover 5 falling off the mounting sleeve 21 as a whole.

[0048] With reference to Figure 3 and Figure 4 The mounting hole edge of the protective cover 5 is provided with a clamping joint 52 which is connected in sliding mode, and the end of the clamping joint 52 towards the mounting sleeve 21 is provided with a hemispherical structure. The side wall of the mounting sleeve 21 is provided with a clamping hole 211 matched with the clamping joint 52. At the same time, the end of the protective cover 5 towards the processing platform 1 is also connected in sliding mode with a positioning pin 53, and the processing platform 1 is provided with a positioning hole 13 matched with the positioning pin 53. The connecting rod 54 is arranged between the positioning pin 53 and the clamping joint 52.

[0049] With reference to Figure 4 In addition, the connecting rod 54 is provided with a reset spring 541, and the two ends of the reset spring 541 are fixedly connected to the connecting rod 54 and the protective cover 5, respectively. In other embodiments, the reset spring 541 can also be replaced by an elastic tab.

[0050] In use, when the lifting platform 2 descends to make the protective cover 5 lap on the processing platform 1, the positioning pin 53 will correspond to the positioning hole 13 on the processing platform 1. Then, the polishing mechanism 4 and the mounting sleeve 21 are continuously controlled to descend, so that the permanent magnet is polished, and at the same time, the edge of the clamping hole 211 on the mounting sleeve 21 pushes the clamping joint 52 to slide away from the mounting sleeve 21, thereby synchronously pushing the positioning pin 53 to be clamped on the processing platform 1, thereby automatically increasing the stability of the protective cover 5 when it is covered, and ensuring the safety during polishing.

[0051] When the polishing is completed, during the process of the lifting platform 2 pulling the polishing mechanism 4 and the mounting sleeve 21 back to the original position, when the clamping hole 211 on the mounting sleeve 21 moves to a position corresponding to the clamping joint 52, the reset spring 541 pushes the connecting rod 54 to move, so that the clamping joint 52 reenters the clamping hole 211, and the positioning pin 53 is separated from the processing platform 1, thereby releasing the limitation of the protective cover 5, and automatically pulling the protective cover 5 to open, so that the use effect is better.

[0052] With reference to Figure 3 and Figure 4At this time, the limiting part is provided as a limiting nut 212, the limiting nut 212 is sleeved and threadedly connected to the mounting sleeve 21. The rotation of the limiting nut 212 can adjust the position of the limiting nut 212 on the mounting sleeve 21, which is convenient to use, and when the clamping joint 52 cooperates with the clamping hole 211, the protective cover 5 just abuts against the upper end of the limiting part. When the clamping joint 52 enters the clamping hole 211, the limiting part can also support and limit the protective cover 5, reduce the possibility of the protective cover 5 causing the clamping joint 52 to be pulled out of the clamping hole 211 again due to its own gravity, and further ensure the stability of the positioning pin 53 when resetting, and reduce the possibility of affecting the subsequent use.

[0053] In actual installation, the clamping joint 52, the positioning pin 53, the connecting rod 54 and the reset spring 541 on the protective cover 5 can be arranged in multiple, and the clamping hole 211 on the mounting sleeve 21 is correspondingly arranged in multiple, thereby increasing the locking effect when the protective cover 5 is covered.

[0054] The implementation principle of the permanent magnet processing equipment according to an embodiment of the application is as follows: in use, the permanent magnet is clamped in the clamp 3, then the lifting table 2 is operated and the motor is started, so that the lifting of the polishing disc 41 can be controlled to polish the permanent magnet. After the processing is completed, the spray head 7 is started to flush the permanent magnet and other components in the work position cavity 11, and the waste water is discharged from the drain pipe 12, then hot air is input into the work position cavity 11 through the hot air pipe 6 to dry the components in the work position cavity 11 and the permanent magnet, thereby making the cleaning relatively convenient and the cleaning effect better, facilitating the subsequent polishing processing of the permanent magnet, and improving the use effect of the processing equipment.
