Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnetic chucks, and particularly relates to a rectangular Halbach permanent magnetic chuck. Background Art

[0002] The permanent magnetic chuck, also known as the magnetic chuck, is a magnetic fixture widely used in the machining fields such as machinery factories and mold factories, which can greatly improve the clamping efficiency of ferromagnetic steel materials. The permanent magnetic chuck uses a high-performance rare earth material neodymium iron boron as the core, and by manually turning the chuck handle, the magnetic force system of the neodymium iron boron inside the chuck is changed, so as to achieve the holding or releasing of the workpiece to be machined.

[0003] When the permanent magnetic chuck holds the workpiece for machining such as milling, a large amount of debris and residues will be generated on the workpiece and fall on the permanent magnetic chuck. The permanent magnetic chuck can only hold the workpiece and cannot handle the debris scattered on the top during the machining of the workpiece. After each workpiece is machined, the staff needs to spend time removing the residues and debris. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rectangular Halbach permanent magnetic chuck, which solves the problem that the existing permanent magnetic chuck can only hold the workpiece and cannot handle the debris scattered on the top during the machining of the workpiece. After each workpiece is machined, the staff needs to spend time removing the residues and debris.

[0022] The following will further elaborate on the above and additional technical features and advantages of the present utility model in conjunction with the accompanying drawings.

[0023] This embodiment provides a technical solution: a rectangular Halbach permanent magnet chuck, as Figure 1 shown, comprising: a permanent magnet chuck 1 and a slag elimination component 2. The slag elimination component 2 is arranged outside the permanent magnet chuck 1 and is used to eliminate the residues accumulated on the upper surface of the permanent magnet chuck 1, saving the time for staff to manually clean and eliminate the residues on the permanent magnet chuck 1, reducing the workload, and enabling the function of eliminating the generated residues while processing when there is a workpiece being processed above the permanent magnet chuck 1. The slag elimination component 2 includes a slag elimination part;

[0024] As Figures 2-4 shown, the slag elimination part includes a high-pressure air pump 21, an air duct 22, a filter screen air suction pipe 23, and a support shell 24. A plurality of air holes 25 are formed in the outer part of the air duct 22. The high-pressure air pump 21 is fixed to one side of the support shell 24 through a support frame. The air duct 22 is fixed to the front of the support shell 24 through two connecting frames, and both the air duct 22 and the air holes 25 are slightly higher than the upper surface of the support shell 24. One end of the air duct 22 is fixed to the air outlet end of the high-pressure air pump 21, one end of the filter screen air suction pipe 23 is fixed to the air inlet end of the high-pressure air pump 21, and L-shaped grooves 3 are formed on both sides of the support shell 24. L-shaped pushing plates 4 are slidably arranged in the two L-shaped grooves 3. Lifting pull rods 5 are rotatably arranged on one side of the two L-shaped pushing plates 4. The permanent magnet chuck 1 is placed inside the support shell 24. When the permanent magnet chuck 1 needs to be taken out of the support shell 24 later, only by pulling up the two L-shaped pushing plates 4 through the lifting pull rods 5, the two L-shaped pushing plates 4 will lift the permanent magnet chuck 1 out of the support shell 24.

[0025] As Figures 2-4 shown, an inlay groove 26 is formed inside the support shell 24. The slag elimination component 2 further includes a start-stop part for controlling the start and stop of the high-pressure air pump 21. The start-stop part is arranged inside the inlay groove 26 and includes a pressure sensor 27 and a controller 28. Both the pressure sensor 27 and the controller 28 are arranged inside the inlay groove 26. The controller 28 is fixed to the bottom of the pressure sensor 27. The pressure sensor 27 and the high-pressure air pump 21 are electrically connected to the controller 28 through the prior art. The threshold for starting and stopping the high-pressure air pump 21 is set in the controller 28. The weight of the permanent magnet chuck 1 placed inside the support shell 24 is fixed, and the weight pressure value of the individual permanent magnet chuck 1 detected by the pressure sensor 27 is fixed and is the minimum threshold, that is, the pressure value for stopping the high-pressure air pump 21 from working. If it is higher than this fixed value, the high-pressure air pump 21 will be started to work.

[0026] As Figures 1-4As shown, the auxiliary slag elimination component 2 further includes a cleaning member. The cleaning member is arranged on one side of the air duct 22. The cleaning member is used to eliminate the dust accumulated at one end of the filter suction pipe 23. The cleaning member includes a connecting pipe 29 and a dust cleaning head 210. One end of the connecting pipe 29 is fixed to one side of the air duct 22, and the other end of the connecting pipe 29 is fixedly connected to the dust cleaning head 210. The connecting pipe 29 diverts a part of the high-pressure gas from the air duct 22 to the dust cleaning head 210 to blow away the dust on the surface of the filter suction pipe 23.

[0027] During use, when the workpiece is placed on the permanent magnetic chuck 1, the pressure exerted by the permanent magnetic chuck 1 and the workpiece on the pressure sensor 27 will cause the pressure value detected by the pressure sensor 27 to increase. The pressure value is transmitted to the controller 28, and the controller 28 will control the high-pressure air pump 21 to start pumping gas into the air duct 22, and blow it to the upper surface of the permanent magnetic chuck 1 through the air holes 25, so as to blow away the debris and residues generated during processing and remaining on the permanent magnetic chuck 1 during workpiece processing, without the need for staff to spend time cleaning the residues and debris later. At the same time, when the high-pressure air pump 21 sends air into the air duct 22, a part of the air is discharged from the connecting pipe 29 and the dust cleaning head 210 to blow off the dust on the filter suction pipe 23, avoiding the blockage of the mesh holes of the filter suction pipe 23 and affecting the slag elimination effect of the slag elimination component.

[0028] The above is only a preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
