[0002] In mechanical processing, in order to ensure the final accuracy and structure of the finished product, the use of subtractive parts manufacturing methods will generate a lot of chips. Most of the processed metal materials are ferrous metals, which have magnetic adsorption characteristics. If the ferrous metal chips are not removed in time on the workbench, it will not only affect the accuracy of component positioning and installation, but also bring safety hazards to operators. At the same time, for some high-precision products, such as chip manufacturing, the magnetically adsorbed metal attached to it is often removed by blowing, brushing, etc., which will microscopically damage the surface of high-precision parts, and if not removed, it will cause problems such as circuit short circuits. Summary of the invention

[0005] The above-mentioned magnetic chip removing rod, the steering gear is fixedly sleeved on the adjusting shaft, one end of the adjusting shaft is connected to the rod body through a bearing, and the other end of the adjusting shaft passes through the rod body and is exposed to connect with the adjusting handle.

[0006] The above-mentioned magnetic chip removing rod, the rotating sleeve is made of non-magnetic silicon oxide ceramic material.

[0007] The above-mentioned magnetic chip removing rod has two through pin holes symmetrically opened on the hole walls on both sides of the through hole of the rotating sleeve, and two positioning holes symmetrically set in the middle of both sides of the strong magnetic block. The positioning pin passes through the pin hole and is inserted into the positioning hole of the strong magnetic block, thereby limiting and fixing the strong magnetic block.

[0008] The magnetic dandruff removing rod has a hand-held handle at the rear end of the rod body.

[0009] The magnetic dandruff remover rod has magnetic poles at both ends of the strong magnetic block in opposite directions, and the magnetic force at both ends of the strong magnetic block is the largest, and the magnetic force gradually weakens toward the middle.

At this time, the strong magnetic block in the rearmost rotating sleeve is perpendicular to the axis of the rod body. Since the two rotating sleeves are connected by transmission gears, all other rotating sleeves are rotated until both ends of the strong magnetic block are close to the outer wall of the rod body, and all the strong magnetic blocks are parallel to each other. Step 3: Hold the magnetic chip remover to the metal chip location, and rely on the strong magnetic effect at both ends of the strong magnetic block to concentrate the metal chips on the surface of the magnetic chip remover; Step 4: After the metal chips are adsorbed, hold the magnetic chip removal rod to the metal chip recovery position; Step 5: Rotate the adjustment handle, the adjustment handle drives the steering gear to rotate, and the steering gear drives the rearmost rotating sleeve to rotate, so that the two ends of the strong magnetic block in the rearmost rotating sleeve are away from the outer wall of the rod body, until the strong magnetic block in the rearmost rotating sleeve is parallel to the axis of the rod body. Since the two rotating sleeves are connected by transmission gears, all other rotating sleeves are rotated until the strong magnetic block is parallel to the axis of the rod body, and all the strong magnetic blocks are in a straight line; Step six: As the two ends of the strong magnetic blocks in the rotating sleeve move away from the outer wall of the rod until the strong magnetic blocks in the rotating sleeve become parallel to the axis of the rod, the magnetic force on the circumferential surface of the rod continues to weaken, and the metal chips adsorbed on the surface of the magnetic chip removal rod are separated from the surface of the magnetic chip removal rod under the action of gravity for recycling.

[0011] The beneficial effects of the present invention are as follows: the present invention utilizes the principle of magnetic field intensity distribution, the magnetic force at the two ends of the strong magnetic block (i.e., the N pole and the S pole) is the largest, and the magnetic force gradually weakens toward the middle, and the middle section is close to zero; when adsorbing metal chips, the two ends of the strong magnetic block are rotated to be close to the outer wall of the rod body, so that the metal chips are concentratedly adsorbed to the surface of the magnetic chip removal rod under the action of the strong magnet; when discharging chips, the two ends of the strong magnetic block are rotated away from the outer wall of the rod body, so that the chips are separated from the surface of the magnetic chip removal rod under the action of gravity. The present invention has a simple overall structure, manufacturing processability and simple operation, and has promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The steering gear 10 is fixedly sleeved on the adjusting shaft 11 , one end of the adjusting shaft 11 is connected to the rod body 1 through a bearing, and the other end of the adjusting shaft 11 passes through the rod body 1 and is exposed to connect with the adjusting handle 13 .

The positioning pin passes through the pin hole 12 and is inserted into the positioning hole of the strong magnetic block 7, thereby limiting and fixing the strong magnetic block 7.

[0022] The rotating sleeve 4 is made of non-magnetic silicon oxide ceramic material. Other materials such as silicon nitride ceramic, carbon fiber, polystyrene, etc. can also be selected, and their economy and cost performance should be considered during production.

[0023] like Figure 4 As shown, the magnetic poles at the two ends of the strong magnetic block 7 are opposite, the magnetic force at the two ends of the strong magnetic block 7 is the largest, and the magnetic force gradually weakens toward the middle, and the magnetic force in the middle section approaches zero. Figure 4 A and B are strong magnetic areas, and C and D are weak magnetic areas.

[0024] A metal chip removal method comprises the following steps: Step 1: When metal chips need to be adsorbed, hold the handle 2 of the magnetic chip removal rod.

[0025] Step 2: Rotate the adjusting handle 13, the adjusting handle 13 drives the steering gear 10 to rotate, and the steering gear 10 drives the rearmost rotating sleeve 4 to rotate, so that both ends of the strong magnetic block 7 in the rearmost rotating sleeve 4 are close to the outer wall of the rod body 1. At this time, the strong magnetic block 7 in the rearmost rotating sleeve 4 is perpendicular to the axis of the rod body 1. Since the two rotating sleeves 4 are connected by the transmission gear 9, all the remaining rotating sleeves 4 are rotated until both ends of the strong magnetic block 7 are close to the outer wall of the rod body 1, and all the strong magnetic blocks 7 are parallel to each other.
