[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0025] Example 2

[0026] Reference Figure 1-5 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] An installation cavity is provided on the upper side of the lower end of the connecting platform 1 corresponding to the magnetic block 2, and the magnetic block 2 is installed at the bottom of the installation cavity, and a fixing cylinder 9 is installed in the installation cavity corresponding to the magnetic block 2. The setting of the fixing cylinder 9 makes it easy to fix and disassemble the magnetic block 2; the lower end of the fixing cylinder 9 abuts against the upper surface of the magnetic block 2, and the upper end of the fixing cylinder 9 is connected to the connecting platform 1 by screws. The setting of the screws makes it easy to disassemble and connect the fixing cylinder 9, thereby making it easy to disassemble the magnetic block 2, so as to facilitate the maintenance of the magnetic block 2; an annular cover plate 10 is sleeved on the upper side of the lower end of the connecting platform 1, and the lower end of the cover plate 10 is clamped on each screw. The setting of the cover plate 10 makes it easy to cover each screw to prevent external debris from clogging the hexagonal bolt hole of the screw and affecting subsequent disassembly.

[0028] A plurality of sockets are provided on the lower end surface of the connecting platform 1 corresponding to the magnetic block 2, and a plurality of magnetic connecting columns 11 are fixed on the upper surface of the adsorption plate 8 corresponding to the sockets. The arrangement of the sockets and the connecting columns 11 makes the connecting platform 1 more stable when driving the connecting seat 3 to rotate; two threaded holes are symmetrically provided on the seat body of the connecting seat 3, and the connecting seat 3 is installed with locking studs 12 through the threaded holes. The arrangement of the locking studs 12 provides an additional locking effect between the connecting platform 1 and the connecting seat 3, that is, the connecting platform 1 and the connecting seat 3 are more secure; a matching accommodating hole is provided at the lower end of the connecting platform 1 corresponding to the locking studs 12, and a matching card groove 13 is provided at the fixing rod 5 and the connecting protrusion 6 corresponding to the seesaw 7. The arrangement of the card groove 13 facilitates the accommodation of the end of the seesaw 7, thereby preventing the seesaw 7 from slipping off the connecting protrusion 6 or the fixing rod 5 when in use.

[0029] Principle and advantages of use: During the use of the utility model, the upper end of the connecting platform 1 is fixed to the external machine tool spindle, and a number of connecting seats 3 are set, and then different tools 4 are installed at the lower end of each connecting seat 3, and then after the connecting seat 3 and the connecting platform 1 are connected to each other, the machine tool spindle drives the connecting platform 1 to rotate, and the connecting platform 1 drives the tool 4 to rotate through the connecting seat 3, thereby realizing the washing and cutting processing; and in the above process, since the bottom of the connecting platform 1 is provided with a magnetic suction block 2 and the inner bottom surface of the upper end of the connecting seat 3 is provided with an adsorption plate 8, that is, when the two are in contact with each other, the magnetic suction block 2 adsorbs the adsorption plate 8 under the action of magnetic attraction, so that the adsorption plate 8 is tightly attached to the lower bottom surface of the connecting platform 1, that is, the connecting seat 3 is tightly attached to the connecting platform 1 at this time, thereby the machine tool spindle can drive the tool 4 to rotate, and since the lower end of the connecting platform 1 is a polygon, that is, the connecting platform 1 drives the connecting seat 3 to rotate more stably.

[0030] At the same time in the above process, since the seesaw 7 is provided, that is, the seesaw 7 is removed when the machine tool is in use, and when the tool 4 needs to be replaced, the end of the seesaw 7 is inserted between the fixed rods 5 and the connecting protrusions 6 on both sides, and then the personnel presses down on the end of the seesaw 7 away from the connecting platform 1, so that the seesaw 7 pushes the connecting seat 3 to move downward, thereby realizing the separation between the connecting seat 3 and the connecting platform 1, and then the new tool 4 is connected to the connecting platform 1 through the connecting seat 3 at its upper end, and the tool replacement is completed.

[0031] In summary, during use, the present solution, through the cooperation between the magnetic block 2 and the adsorption plate 8, makes the connecting seat 3 and the connecting platform 1 magnetically connected, and then when the tool 4 is disassembled, it is only necessary to pry the connecting seat 3 downward through the rocker 7, and when the tool 4 needs to be installed, it is only necessary to push the connecting seat 3 upward, that is, compared with the installation method through bolts in the traditional solution, the present solution has fewer operating steps when used, which effectively shortens the time for personnel to replace the tool. The traditional solution can only clamp cylindrical tools, while the present solution does not limit the handle shape of the tool 4, which can be installed with the connecting seat 3 by bolts or by welding, so that the personnel only need to complete the connection between the tool 4 and the connecting seat 3 in advance, and when the tool 4 is replaced on the machine tool later, the connecting seat 3 can be directly replaced, which makes the present solution more adaptable to the tool 4 when used.

[0032] It should be further explained that the setting of the fixing tube 9 and the screws facilitates the disassembly of the magnetic block 2, so as to facilitate the maintenance of the magnetic block 2; the setting of the cover plate 10 facilitates the shielding of each screw to prevent foreign objects from clogging the hexagon socket bolt hole of the screw and affecting the subsequent disassembly; the setting of the jack and the connecting column 11 makes the connecting platform 1 more stable when driving the connecting seat 3 to rotate; the setting of the locking stud 12 provides an additional locking effect between the connecting platform 1 and the connecting seat 3, that is, makes the connecting platform 1 and the connecting seat 3 more secure; the setting of the slot 13 facilitates the accommodation of the end of the rocker 7, thereby preventing the rocker 7 from slipping off the connecting protrusion 6 or the fixing rod 5 when in use.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
