Description

Technical Field

[0001] This utility model belongs to the field of magnetic fastener technology and relates to a magnetic fastener base. Background Technology

[0002] Before processing, workpieces are usually fixed on the worktable of the processing equipment using some tooling fixtures. When the workpiece structure is complex, several different machines are needed to process it in sequence. Therefore, each time the processing equipment is changed, the fixtures need to be disassembled and reassembled, which is time-consuming, labor-intensive and very troublesome. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing workpiece clamping and fixing process by proposing a magnetic fixing seat that can magnetically fix the workpiece to the worktable and is easy to assemble and disassemble.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A magnetic fixing base includes a housing and a magnet assembly disposed within the housing. The housing has a magnetic adsorption surface. A plane passing through the axis of the magnet assembly divides the magnet assembly into a first magnetic pole portion and a second magnetic pole portion. The magnetic poles of the first and second magnetic pole portions face opposite directions. The magnet assembly is further divided into a fixed magnetic assembly and a movable magnetic assembly. The fixed magnetic assembly is fixedly disposed within the inner cavity of the housing, and the movable magnetic assembly is rotatably disposed within the inner cavity of the housing. A rotating component is disposed on the housing, which drives the movable magnetic assembly to rotate when it rotates. The rotating component and the housing support are further provided with a positioning mechanism, which is used to lock the position of the rotating component after rotation, so that the first magnetic pole portion of the movable magnetic assembly can be directly opposite the first magnetic pole portion or the second magnetic pole portion of the fixed magnetic assembly, respectively.

[0006] In the aforementioned magnetic fixing base, the positioning mechanism includes a positioning block fixed on the housing and several positioning slots opened on the rotating component. The positioning block is embedded in the corresponding positioning slot. The rotating component can rise and fall relative to the housing and the movable magnetic assembly. Pressing the rotating component will cause the positioning block to exit the positioning slot and unlock. After rotating the rotating component 180°, a spring is provided inside the housing to push the rotating component to rise and reset, so that the positioning block is embedded in the positioning slot to form a lock.

[0007] In the aforementioned magnetic fixing base, there are two positioning blocks arranged symmetrically, and two positioning slots, with the positions of the two positioning slots corresponding one-to-one with the positions of the positioning blocks.

[0008] In the aforementioned magnetic fixing base, the positioning block is provided with a guide slope.

[0009] In the aforementioned magnetic fixing base, the positioning mechanism further includes a guide arc groove formed on the housing and a guide post fixed on the movable magnetic assembly. The rotating component has a guide hole corresponding to the position of the guide post. The guide post is inserted into the guide hole, and the rotating component can move up and down relative to the movable magnetic assembly along the guide post. One end of the guide post is inserted into the guide arc groove. When the rotating component drives the movable magnetic assembly to rotate, the guide post can rotate synchronously along the guide arc groove. When the first magnetic pole part of the movable magnetic assembly is directly opposite the first magnetic pole part or the second magnetic pole part of the fixed magnetic assembly, the guide post abuts against the two groove surfaces of the guide arc groove respectively.

[0010] In the aforementioned magnetic fixing base, there are two guide posts and two guide arc grooves, and the two guide arc grooves are coaxially arranged with the rotating component.

[0011] In the aforementioned magnetic fixing base, the rotating component includes a rotating shaft, a turntable, and a handle. One end of the rotating shaft is fixedly connected to the turntable, and the other end extends out of the housing and is fixedly connected to the handle. The positioning slot and guide hole are formed on the turntable.

[0012] In the aforementioned magnetic fixing base, the housing includes a housing body and a cover plate. The housing body has a mounting hole, and the magnet assembly is rotatably disposed in the mounting hole. The cover plate has a recessed hole, and the turntable is movably embedded in the recessed hole. The housing body and the cover plate are fixedly connected by fasteners.

[0013] In the aforementioned magnetic fixing base, the housing is provided with several mounting surfaces for mounting the magnetic fixing base.

[0014] In the aforementioned magnetic mounting base, a gasket is provided between the fixed magnetic assembly and the movable magnetic assembly. The gasket is designed to provide lubrication and reduce friction.

[0015] In one of the aforementioned magnetic mounting bases, a notch is also provided on the magnetic adsorption surface. The notch design allows the magnetic discharge from the magnetic mounting base to be more concentrated.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the rotating part rotates 180° back and forth, the first magnetic pole of the movable magnetic assembly can be directly aligned with the first or second magnetic pole of the fixed magnetic assembly. When the first magnetic pole of the movable magnetic assembly is directly aligned with the first magnetic pole of the fixed magnetic assembly, the magnetic fixing seat has an attractive force; when the first magnetic pole of the movable magnetic assembly is directly aligned with the second magnetic pole of the fixed magnetic assembly, the magnetic fixing seat has no attractive force. After the magnetic fixing seat of this utility model is fixed to the workpiece, the working platform can be held and released by rotating the handle. The operation is simple and convenient, thus realizing quick equipment change.

[0018] 2. By pressing the handle, the positioning block is separated from the positioning slot, thus unlocking. At this time, the rotating part can be rotated, which drives the movable magnetic group to rotate synchronously. When the guide post rotates to abut against the groove surface of the guide arc groove, it means that the rotation is in place. Release the handle, and the spring will automatically push the rotating part to lift up, and the positioning block will be embedded in the positioning slot to form a lock. The positioning mechanism of this utility model is simple to operate and accurate in positioning. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, the magnetic fixing base of this utility model includes a housing 1 and a magnet assembly disposed within the housing 1. The housing 1 is provided with a magnetic adsorption surface 2. A plane passing through the axis of the magnet assembly divides the magnet assembly into a first magnetic pole portion 3 and a second magnetic pole portion 4. The magnetic poles of the first magnetic pole portion 3 and the second magnetic pole portion 4 face opposite directions. The magnet assembly is further divided into a fixed magnetic assembly 5 and a movable magnetic assembly 6. The fixed magnetic assembly 5 is fixedly disposed in the inner cavity of the housing 1, and the movable magnetic assembly 6 is rotatably disposed in the inner cavity of the housing 1. A rotating component is provided on the housing 1, which can drive the movable magnetic assembly 6 to rotate when it rotates.

[0027] The rotating component and the housing 1 support are also provided with a positioning mechanism, which is used to lock the position of the rotating component after rotation, so that the first magnetic pole part 3 of the movable magnetic group 6 can be directly opposite the first magnetic pole part 3 or the second magnetic pole part 4 of the fixed magnetic group 5 respectively.

[0028] The first magnetic pole part 3 is set as the N pole and the second magnetic pole part 4 is set as the S pole. When the N pole of the movable magnetic group 6 and the S pole of the fixed magnetic group 5 are directly aligned vertically, the magnetic fixing seat has an attractive force. When the S pole of the movable magnetic group 6 and the N pole of the fixed magnetic group 5 are directly aligned vertically, the magnetic fixing seat has no attractive force.

[0029] like Figure 4 As shown, the positioning mechanism includes positioning blocks 7 fixed on the housing 1 and several positioning slots 8 formed on the rotating component. The positioning blocks 7 are embedded in the corresponding positioning slots 8. The rotating component can rise and fall relative to the housing 1 and the movable magnetic assembly 6. Pressing the rotating component causes the positioning blocks 7 to exit the positioning slots 8, thus unlocking the mechanism. After rotating the rotating component 180°, a spring 9 inside the housing 1 pushes the rotating component to rise and reset, so that the positioning blocks 7 are embedded in the positioning slots 8 to form a lock. There are two positioning blocks 7, which are symmetrically arranged. There are also two positioning slots 8, and the positions of the two positioning slots 8 correspond one-to-one with the positions of the positioning blocks 7. A guide slope 10 is formed on the positioning block 7.

[0030] like Figure 5 As shown, the positioning mechanism further includes a guide arc groove 11 formed on the housing 1 and a guide post 12 fixed on the movable magnetic assembly 6. A guide hole 13 corresponding to the position of the guide post 12 is formed on the rotating component. The guide post 12 is inserted into the guide hole 13, allowing the rotating component to move up and down relative to the movable magnetic assembly 6 along the guide post 12. One end of the guide post 12 is inserted into the guide arc groove 11. When the rotating component drives the movable magnetic assembly 6 to rotate, the guide post 12 can rotate synchronously along the guide arc groove 11. When the first magnetic pole portion 3 of the movable magnetic assembly 6 is directly opposite the first magnetic pole portion 3 or the second magnetic pole portion 4 of the fixed magnetic assembly 5, the guide post 12 abuts against the two groove surfaces of the guide arc groove 11. There are two guide posts 12 and two guide arc grooves 11, both of which are coaxially arranged with the rotating component.

[0031] like Figure 3As shown, the rotating component includes a rotating shaft 14, a turntable 15, and a handle 16. One end of the rotating shaft 14 is fixedly connected to the turntable 15, and the other end extends through the housing 1 and is fixedly connected to the handle 16. The positioning slot 8 and guide hole 13 are formed on the turntable 15. The housing 1 includes a housing body 17 and a cover plate 18. A mounting hole 19 is formed on the housing body 17, and the magnet assembly is rotatably disposed in the mounting hole 19. A recessed hole 20 is formed on the cover plate 18, and the turntable 15 is movably embedded in the recessed hole 20. The housing body 17 and the cover plate 18 are fixedly connected by fasteners. A gasket 22 is provided between the fixed magnet assembly 5 and the movable magnet assembly 6. The gasket 22 is designed to provide lubrication and reduce friction.

[0032] like Figure 1 As shown, the housing 1 is provided with several mounting surfaces 21 for mounting magnetic fixing seats. The side and top surfaces of the housing 1 can both serve as mounting surfaces 21. The workpiece is fixed to the magnetic fixing seat through the mounting surfaces 21, and then the magnetic fixing seat magnetically fixes the workpiece to the worktable of the processing equipment. A notch 23 is also provided on the magnetic attraction surface 2. The design of the notch 23 allows the magnetic discharge from the magnetic fixing seat to be more concentrated.
