However, in actual working conditions, due to the large lateral space occupied by the magnet, it is difficult to ensure that the flatness of the magnet and the magnet suction plate at any point meets the requirements, and the production of the magnet suction plate is also difficult to ensure that its suction surface is smooth and flat. If the flatness of the magnet and the magnet suction plate cannot meet the requirements, long-term use will cause the magnet suction force to decay, thereby causing the device to fall, causing serious consequences.

[0020] The present invention is further described below in conjunction with the accompanying drawings.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the present invention and are not intended to limit the present invention.

[0022] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by the terms "upper", "lower", "inside" and "outside" should be understood in a broad sense and are not used to limit the scope of protection of the present invention. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The magnet suction force fine-tuning device comprises a magnet suction plate 1, a magnet positioning plate 2, a magnet 4 and a magnet mounting seat 3, wherein an upper tank body connecting portion is provided at the upper end of the magnet suction plate 1, the lower surface of the magnet suction plate 1 is connected to the upper surface of the magnet positioning plate 2, the magnet 4 can be lifted and placed in the magnet mounting hole of the magnet positioning plate 2, the magnet 4 generates an adsorption force on the magnet suction plate 1, a magnet mounting groove is provided on the upper surface of the magnet mounting seat 3, the magnet 4 is placed in the magnet mounting groove, a magnet bolt hole is vertically opened on the lower surface of the magnet 4, a magnet mounting seat bolt hole is vertically opened on the lower surface of the magnet mounting seat 3, and the magnet mounting seat bolt hole is connected to the magnet mounting groove The magnet 4 is connected to the magnet mounting seat 3 and its center axis is coaxial with the center axis of the magnet bolt hole. The magnet 4 is connected to the magnet mounting seat 3 by bolts. The lower surface of the magnet mounting seat 3 is provided with a lower tank body connecting part, including a fine-tuning screw 6 and a locking bolt 5. The fine-tuning screw 6 is screwed to the magnet mounting seat 3 through the bolt hole of the magnet mounting seat. The threaded end of the locking bolt 5 passes through the locking bolt through hole of the fine-tuning screw 6 from bottom to top and is screwed to the magnet 4 through the magnet bolt hole. The lower end of the locking bolt 5 is provided with a fine-tuning screw connecting part. The locking bolt 5 is connected to the fine-tuning screw 6 through the fine-tuning screw connecting part. When the fine-tuning screw 6 rotates, the lifting and lowering of the magnet 4 can be controlled.

[0024] like Figure 1 As shown, when in use, first place the magnet 4 in the magnet mounting groove on the magnet mounting seat 3, align the magnet bolt hole opened on the lower surface of the magnet 4 with the bolt hole of the magnet mounting seat, then, fix the upper surface of the magnet positioning plate 2 with the lower surface of the magnet suction plate 1, and let the magnet 4 be aligned with the magnet mounting hole of the magnet positioning plate 2 and inserted. At this time, the magnet 4 will produce an adsorption force on the magnet suction plate 1, and the fine-tuning screw 6 is screwed into the magnet mounting seat threaded hole on the lower surface of the magnet mounting seat 3, and enters the magnet mounting groove through the magnet mounting seat threaded hole. The threaded end of the locking bolt 5 passes through the locking bolt through hole of the fine-tuning screw 6 from bottom to top and is screwed with the magnet 4 through the magnet bolt hole, and the lower end of the locking bolt 5 is provided with a fine-tuning screw connecting part, and the locking bolt 5 is connected with the fine-tuning screw 6 through the fine-tuning screw connecting part, so that the magnet 4 is stably connected to the magnet mounting seat 3. At this time, continue to rotate the fine-tuning screw 6 to make the magnet 4 rise and fall in the magnet mounting groove, so as to achieve fine-tuning of the magnetic force.

[0025] Furthermore, it includes a locking nut 9 , which is threadedly connected to the fine-tuning screw 6 , and the upper surface of the locking nut 9 abuts against the lower surface of the magnet mounting seat 3 .

[0026] Since the upper surface of the locking nut 9 abuts against the lower surface of the magnet mounting base 3, when the locking nut 9 rotates, the locking nut 9 will not produce axial displacement, while the fine-tuning screw 6 will produce axial displacement under the action of the thread, thereby controlling the fine-tuning screw 6 to enter and exit the fine-tuning screw connecting threaded hole. The present scheme uses the locking nut 9 to control the fine-tuning screw 6 to enter and exit the fine-tuning screw connecting threaded hole, which can be used with a wrench, saving manpower, and the operator can assist in judging the degree of magnetic fine-tuning by observing the degree of rotation of the locking nut 9.

[0027] Furthermore, it includes a spherical washer 7, which is connected to the outer wall of the fine-tuning screw 6 and is located between the upper surface of the locking nut 9 and the lower surface of the magnet mounting seat 3. The spherical washer 7 abuts against the magnet mounting seat 3, and the locking nut 9 abuts against the spherical washer 7.

[0028] Spherical washers are usually designed with a spherical surface on one side and a flat surface on the other side. When installed on a bolt or nut, the spherical surface can rotate relative to the flat surface to adapt to the irregular or tilted state of the mounting surface, thereby ensuring the verticality or parallelism of the fastener.

[0029] Furthermore, it includes a wedge washer 8, which is connected to the outer wall of the fine-tuning screw 6 and is located between the lower surface of the spherical washer 7 and the upper surface of the locking nut 9. The wedge washer 8 abuts against the spherical washer 7, and the locking nut 9 abuts against the wedge washer 8.

[0030] Similarly, the wedge-shaped washer 8 provides better support and parallelism adjustment, making the entire device more stable and reliable during use. At the same time, by using the spherical washer 7 and the wedge-shaped washer 8, the direct friction between the components is reduced, the risk of wear is reduced, and the service life of the device is extended.

[0031] Furthermore, it includes a plurality of positioning pins, a plurality of pin positioning holes are provided on the magnet positioning plate 2, a plurality of pin connecting holes are provided on the lower surface of the magnet suction plate 1, and the positioning pins pass through the pin positioning holes from bottom to top and are connected with the pin connecting holes.

[0032] By using positioning pins to connect the magnet suction plate 1 and the magnet positioning plate 2, the installation process is simplified, so that the user can quickly and accurately complete the assembly of the device while ensuring the alignment accuracy between the various components.

[0033] Furthermore, the locking portion of the fine-tuning screw is a screw handle. When the locking bolt 5 is screwed into the locking bolt hole, the upper end surface of the fine-tuning screw connecting portion abuts against the lower end of the fine-tuning screw 6.

[0034] In this solution, the fine-tuning screw connection portion adopts a screw handle to facilitate processing and simplify the device.
