Description

Technical Field

[0001] This utility model relates to the field of permanent magnet chuck technology, specifically a highly reliable square grid-type strong permanent magnet chuck. Background Technology

[0002] The square grid high-strength permanent magnet chuck is an industrial device that uses permanent magnet materials to generate a strong magnetic field. It is mainly used to adsorb, fix or move metal workpieces. The square grid structure design usually refers to the arrangement of magnetic poles. During the processing of metal workpieces, the permanent magnets are used to fix the workpieces. It is easy to operate and safe.

[0003] In the prior art, Chinese patent application number CN202220049831.8 discloses a high-safety, powerful square permanent magnet chuck, including a permanent magnet chuck, a fixed plate fixedly installed on one side of the permanent magnet chuck, a sliding groove opened on the upper part of the fixed plate, two sliding blocks slidably installed in the sliding groove, a sliding bracket fixedly installed on one side of each of the two sliding blocks, and a driven rod rotatably installed on the other side of each of the two sliding blocks. The same driving rod is rotatably installed on the side of the two driven rods that are close to each other, and a fixed rod is slidably installed on the driving rod. The fixed rod is adapted to the fixed plate. By setting up the sliding bracket, when installing a workpiece, the two sliding brackets are used to fix the position of the workpiece on the permanent magnet chuck, thereby ensuring the stability of the workpiece during the magnetic force activation process, thus avoiding affecting the processing accuracy of the equipment, or even causing damage to the cutting tool or workpiece, and eliminating safety hazards.

[0004] Based on the above information, it can be seen that the existing technology can further improve stability by clamping on the basis of magnetic adsorption. However, in actual use, the clamping structure in the existing technology is a strip structure, which cannot adapt to the clamping operation of workpieces with different shapes. Utility Model Content

[0005] The purpose of this invention is to provide a highly reliable square grid-type high-strength permanent magnet chuck to solve the problem mentioned in the background art of being unable to clamp irregularly shaped workpieces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly reliable square grid powerful permanent magnet chuck, comprising a placement platform placed on a machine tool, a square grid chuck fixedly installed on the upper surface of the placement platform, the square grid chuck being made of permanent magnet material, and the upper surface of the square grid chuck having intersecting horizontal and vertical dividing grooves; two adjusting frames are installed above the placement platform, the adjusting frames having an "n" shaped structure, and connecting sliders are fixedly installed at the bottom ends of the left and right sides of the adjusting frames, and a limit mechanism is provided inside the adjusting frames; a lifting frame that cooperates with the square grid chuck is installed inside the placement platform, and the lifting frame is used to lift the processing debris upwards.

[0007] Preferably, the connecting slider and the limiting groove form a front-to-back sliding structure, and the limiting groove is a strip structure opened on the left and right sides of the placement platform, and the connecting slider is threaded with fixing bolts on its side.

[0008] Preferably, the limiting mechanism includes a positioning rod installed on the upper end of the adjusting frame, and the positioning rod and the adjusting frame form a through sliding structure.

[0009] Preferably, the positioning rods are evenly distributed at equal intervals, and a compression ball is fixedly installed at the top of the positioning rod, and the compression ball is made of soft rubber.

[0010] Preferably, an elastic band is fixedly installed on the side of the adjustment frame, and the position of the elastic band corresponds to the position of the positioning rod.

[0011] Preferably, connecting rods are fixedly installed on the lower surface of the four corners of the lifting frame, and the connecting rods and the receiving slots opened inside the placement platform form an insert-type lifting structure, and a blocking block is fixedly installed at the upper end of the receiving slot.

[0012] Preferably, an electromagnet is fixedly installed at the lower end of the connecting rod, and the electromagnet is magnetically attracted to the grid suction cup. The electromagnet is connected to a battery fixedly installed inside the placement platform via a connecting wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this highly reliable square grid powerful permanent magnet chuck adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The metal workpiece is initially fixed by being attracted to the placement platform by the magnetic force of the square suction cup. Then, the fixing bolts are loosened and the connecting slider is slid in the limit groove to change the position of the adjustment frame. Finally, the workpiece is clamped by the adjustment frame to achieve a better fixing effect and improve the reliability during processing.

[0015] Furthermore, when using the adjusting frame to clamp the workpiece, the positioning rod at the upper end of the adjusting frame contacts the workpiece first. Under the squeezing action of the workpiece, the positioning rod slides relative to the adjusting frame. Finally, the top of the positioning rod forms a shape that fits against the surface of the workpiece. At the same time, under the limiting action of the elastic band, the fixing effect on the workpiece is further improved, thus improving the reliability of the processing.

[0016] 2. After processing, turn on the electromagnet (at this time, the battery supplies power to the electromagnet through the connecting wires), so that the electromagnet generates magnetism. Under the action of magnetism, the electromagnet attracts the square suction cup, thereby causing the connecting rod to move upward inside the receiving groove. Finally, the connecting rod is used to lift the lifting frame upward, so that the lifting frame lifts the debris in the groove of the placement platform, which is convenient for subsequent cleaning operations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-4To improve reliability during processing (i.e., enhance fixation stability), this embodiment provides the following technical solution, specifically: a placement platform 1 placed on a machine tool; a grid suction cup 2 fixedly installed on the upper surface of the placement platform 1; the grid suction cup 2 is made of permanent magnet material, and the upper surface of the grid suction cup 2 has intersecting horizontal and vertical dividing grooves 3; two adjusting frames 4 are installed above the placement platform 1, and the adjusting frames 4 have an "n" shaped structure; connecting sliders 5 are fixedly installed at the bottom ends of the left and right sides of the adjusting frames 4; a limit mechanism is provided inside the adjusting frames 4; the connecting sliders 5... The limiting slide 6 forms a front-to-back sliding structure with the limiting slide 6, which is a strip structure opened on the left and right sides of the placement platform 1. The limiting slide 6 is connected to the side of the slider 5 and the threaded fixing bolt 7 is installed. The limiting mechanism includes a positioning rod 8 installed on the upper end of the adjusting frame 4. The positioning rod 8 and the adjusting frame 4 form a through sliding structure. The positioning rods 8 are evenly distributed at equal intervals. The top of the positioning rod 8 is fixedly installed with a compression ball 9, which is made of soft rubber. The side of the adjusting frame 4 is fixedly installed with an elastic band 10, and the position of the elastic band 10 corresponds to the position of the positioning rod 8.

[0027] When using the device, firstly, the placement platform 1 is fixedly installed onto the machine tool using bolts. Then, the workpiece to be processed is placed above the placement platform 1. At this time, the magnetic effect of the square suction cup 2 is used to attract the workpiece, achieving the purpose of initial fixation. Then, the fixing bolt 7 (the fixing bolt 7 is used to fix the connecting slider 5 to the limiting slide groove 6) is loosened. Then, the connecting slider 5 is slid in the limiting slide groove 6 to change the position of the adjusting frame 4. The two adjusting frames 4 are used to clamp and fix the workpiece. During clamping, the positioning rod 8 at the upper end of the adjusting frame 4 is pressed against the outer surface of the workpiece. At this time, the positioning rod 8 at the pressing position slides relative to the adjusting frame 4, and finally makes the positioning rod 8 form a groove shape that fits against the surface of the workpiece (the elastic compression of the elastic band 10 keeps the positioning rod 8 in position), achieving a better clamping effect for irregular workpieces, thereby improving the reliability during workpiece processing.

[0028] Example 2: Please refer to Figures 5-7 In order to facilitate subsequent cleaning of debris, this embodiment provides the following technical solution, which specifically discloses: A lifting frame 11 that cooperates with the grid suction cup 2 is installed inside the placement platform 1. The lifting frame 11 is used to lift the processing debris upward. Connecting rods 12 are fixedly installed on the lower surface of the four corners of the lifting frame 11. The connecting rods 12 and the receiving groove 13 opened inside the placement platform 1 form an insertion lifting structure. A blocking block 17 is fixedly installed at the upper end of the receiving groove 13. An electromagnet 14 is fixedly installed at the lower end of the connecting rod 12. The electromagnet 14 is magnetically attracted to the grid suction cup 2. The electromagnet 14 is connected to the battery 15 fixedly installed inside the placement platform 1 through the connecting wire 16.

[0029] When the workpiece is finished and removed, the electromagnet 14 inside the placement platform 1 is activated (power is supplied to the electromagnet 14 via the connecting wire 16 using the battery 15 inside the placement platform 1, and the electromagnet 14 is activated using a button on the outside of the placement platform 1). At this time, the electromagnet 14 generates magnetism, and under the magnetic attraction between the electromagnet 14 and the square suction cup 2, the connecting rod 12 moves upward inside the receiving groove 13 (the maximum movement position of the connecting rod 12 is limited by the blocking block 17). Under the pushing action of the connecting rod 12, the lifting frame 11 moves upward, thereby raising the surface position of the debris that has fallen from the groove inside the placement platform 1, making it easier for subsequent cleaning operations.
