Description

Technical Field

[0001] This utility model relates to a clamp, and more particularly to an improved structure of an annular suction cup. Background Technology

[0002] like Figure 1 As shown, a traditional annular chuck includes an annular electromagnet 101 and a chuck base 102. The annular electromagnet 101 is installed inside the chuck base 102. Its disadvantages are: 1. It requires a DC power supply. If the power is interrupted due to a malfunction during operation, the annular electromagnet 101 will lose its magnetism, potentially causing accidents. 2. It cannot operate for extended periods because it requires current to generate a magnetic field. Prolonged operation will produce high temperatures. If it is adsorbing thin-walled workpieces, excessively high temperatures will cause workpiece deformation, resulting in machining errors, and in severe cases, rendering the workpiece unusable. Utility Model Content

[0003] The purpose of this invention is to provide an improved structure for a ring-shaped suction cup that is reliable and easy to operate.

[0004] To achieve the above objectives, the technical solution of this utility model is:

[0005] This utility model is an improved structure of a ring-shaped suction cup, including a top plate, a bottom plate, and one or more suction components;

[0006] The bottom surface of the top plate is fixed to the top surface of the bottom plate. The top plate has one or more stepped holes in the middle. Multiple through slots are provided around the stepped holes. One or more suction components are respectively fitted into one or more stepped holes in the middle of the top plate and located between the top plate and the bottom plate.

[0007] The suction assembly includes a linkage plate, multiple axial components, a handle, and a limiting pin. The linkage plate is rotatably mounted between the top plate and the bottom plate. The upper parts of the multiple axial components are respectively fixedly mounted in multiple through slots in the top plate, and the lower parts of the multiple axial components are respectively fixedly mounted on the linkage plate. The inner end of the handle is fixed to the side wall of the linkage plate, and the outer end of the handle extends out of the top plate and the bottom plate. The upper end of the limiting pin is fixed to the bottom surface of the linkage plate, and the lower part of the limiting pin is gapped into an arc-shaped limiting groove in the bottom plate.

[0008] The linkage plate is movably fitted into the stepped hole in the middle of the top plate.

[0009] The axial assembly includes an upper magnetic guide block, an upper magnet, a lower magnetic guide block, and a lower magnet group. The upper magnetic guide block has a long slot with an open top in its center. The upper magnetic guide block is fixedly installed in a through slot in the top plate, and the upper magnet is installed at the bottom of the long slot. The lower magnetic guide block is fixedly installed in the lower magnetic guide slot of the linkage plate. The lower magnetic guide block has an upwardly protruding partition in its center. The lower magnet group consists of two lower magnets, which are installed on the top surface of the lower magnetic guide block and separated by the partition. The multiple upper magnets in the axial assemblies are divided into odd-numbered groups and even-numbered groups. The left and right magnetic poles of the upper magnets in the odd-numbered axial assemblies are S and N poles, respectively, while those in the even-numbered groups... In the axial assembly of the group, the left and right magnetic poles of the upper magnet are N and S poles, respectively; the multiple lower magnet groups in the multiple axial assemblies are divided into odd-numbered groups and even-numbered groups. In the two lower magnets of the odd-numbered group, the upper and lower magnetic poles of the left lower magnet are N and S poles, and the upper and lower magnetic poles of the right lower magnet are S and N poles, respectively. In the two lower magnets of the even-numbered group, the upper and lower magnetic poles of the left lower magnet are S and N poles, respectively, and the upper and lower magnetic poles of the right lower magnet are N and S poles, respectively. When the odd-numbered groups of the upper magnets are opposite the odd-numbered groups of the lower magnets, the group is in a demagnetized state; when the odd-numbered groups of the upper magnets are opposite the even-numbered groups of the lower magnets, the group is in a demagnetized state.

[0010] The axial assembly also includes a sealing block; the sealing block is fixed to the upper part of the long groove of the upper magnetic block.

[0011] The top plate has a side groove on its side wall, which communicates with the stepped hole; the handle in the suction assembly extends out from the side groove of the top plate.

[0012] After adopting the above solution, since the suction assembly of this utility model includes a linkage disk, multiple axial components, a handle, and a limiting pin, and the magnetic source in the axial components is a permanent magnet, which does not generate high temperature under normal working conditions and converts the magnetic field mechanically, the performance reliability of the suction cup is very good when it is working. In addition, this utility model changes the relative position of the upper magnet and the lower magnet group in the axial components by rotating the linkage disk, thereby making the suction assembly in a demagnetized or demagnetized state, realizing the fixing and loosening of the processed parts, and the operation is very simple.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0023] like Figures 2-7 As shown, this utility model is an improved structure of a ring suction cup, including a top plate 1, a bottom plate 2, and four suction components 3;

[0024] The bottom surface of the top plate 1 is fixed to the top surface of the bottom plate 2. The top plate 1 has four stepped holes 11 in the middle. Multiple through slots 12 are provided around the stepped holes 11. The side wall of the top plate 1 has a side slot 13, which communicates with the stepped holes 11. Four suction components 3 are respectively fitted into the four stepped holes 11 in the middle of the top plate 1 and located between the top plate 1 and the bottom plate 2.

[0025] The suction assembly 3 includes a linkage disk 31, multiple axial components 32, a handle 33, and a limiting pin 34. The linkage disk 31 is rotatably installed between the top plate 1 and the bottom plate 2, that is, the linkage disk 31 is movably fitted into the stepped hole 11 in the middle of the top plate 1, and the bottom protrusion 312 of the linkage disk 31 abuts against the stepped surface of the stepped hole 11 of the top plate 1. The upper parts of the multiple axial components 32 are respectively fixedly installed in multiple through slots 12 of the top plate 1, and the lower parts of the multiple axial components 32 are respectively fixedly installed on the linkage disk 31. The inner end of the handle 33 is fixed on the side wall of the linkage disk 31, and the outer end of the handle 33 extends out of the top plate 1 and the bottom plate 2 from the side slot 13 of the top plate 1. The upper end of the limiting pin 34 is fixed on the bottom surface of the linkage disk 31, and the lower part of the limiting pin 34 is gap-fitted into the arc-shaped limiting groove 21 on the bottom plate 2.

[0026] The axial assembly 32 includes an upper magnetic guide block 321, an upper magnet 322, a lower magnetic guide block 323, a lower magnet assembly 324, and a sealing block 325. The upper magnetic guide block 321 has a long groove 3211 with an open upper end in the middle. The upper magnetic guide block 321 is fixedly installed in the through groove 12 of the top plate 1. The upper magnet 322 is installed at the bottom of the long groove 3211 of the magnetic guide block 321. The sealing block 325 is fixed at the upper part of the long groove 3211 of the upper magnetic guide block 321, that is, above the upper magnetic guide block 321. The lower magnetic guide block 323 is fixedly installed in the lower magnetic guide groove 311 of the linkage disk 31. The lower magnetic guide block 323 has an upwardly protruding partition 3231 in the middle. The lower magnet assembly 324 is composed of two lower magnets 3241 and 3242. The two lower magnets 3241 and 3242 are installed on the top surface of the lower magnetic guide block 323 and separated by the partition 3231.

[0027] like Figure 8 , Figure 9 As shown, the multiple upper magnets 322 in the multiple axial components 32 are divided into odd-numbered groups and even-numbered groups. The left and right magnetic poles of the upper magnets 322 in the odd-numbered group are S poles and N poles, respectively, while the left and right magnetic poles of the upper magnets 322 in the even-numbered group are N poles and S poles, respectively. The multiple lower magnet groups 324 in the multiple axial components 32 are also divided into odd-numbered groups and even-numbered groups. In the two lower magnets 3241 and 3242 of the odd-numbered group, the upper and lower magnetic poles of the left lower magnet 3241 are... The upper and lower magnetic poles of the right lower magnet 3242 are S and N poles, respectively. In the even-numbered lower magnet group 324, the upper and lower magnetic poles of the left lower magnet 3241 are S and N poles, respectively, and the upper and lower magnetic poles of the right lower magnet 3242 are N and S poles, respectively. When the odd-numbered groups of the upper magnet 322 are opposite to the odd-numbered groups of the lower magnet group 324, the magnet is in a demagnetized state. When the odd-numbered groups of the upper magnet 322 are opposite to the even-numbered groups of the lower magnet group 324, the magnet is in a demagnetized state.

[0028] The working principle of this utility model:

[0029] like Figure 2 , Figure 5 As shown, rotating the handle 33 in the attraction assembly 3 drives the linkage disk 31 to rotate. The rotation of the linkage disk 31 changes the relative position of the upper magnet 322 and the lower magnet group 324 in the axial assembly 32, thereby making the attraction assembly 3 in a demagnetized or demagnetized state, realizing the fixing and loosening of the processed parts.

All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
