Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically a manual tool adjustment and positioning device for a milling machine based on a magnetic conductive circuit. Background Technology

[0002] In the processing of copper strip, defects such as oxidation, indentation, cracks, and segregation on the surface of hot-rolled or continuously cast strip are removed by milling with a milling cutter. This is the milling machine equipment. The high ductility of copper can easily cause chips to stick together, requiring frequent cleaning and adjustment of the cutter.

[0003] The current manual tool adjustment device for milling machines has the following problems: (1) Difficulty in precision control Human error: Relying on the operator's experience and feel, it is easy to cause inaccurate tool alignment due to visual errors and tactile deviations, making it difficult to ensure consistency.

[0004] Limitations of measuring tools: When using traditional tools such as dial indicators and feeler gauges, reading errors or tool wear (such as probe deformation) may mislead the tool adjustment results. Using feeler gauges and dial indicators requires repeated adjustments, with each adjustment taking ≥20 minutes. Furthermore, visual inspection reveals a 0.1-0.2mm error in tool contact, resulting in stepped tool marks on the copper plate surface.

[0005] (2) Inefficiency Frequent tool adjustments are time-consuming: repeated measurements and adjustments are required, especially for milling machines, where high positional accuracy is required on both sides, and the time cost of repeated calibration is significant.

[0006] (3) Safety and health risks Operational safety hazards: When manually adjusting the blade, close contact with the rotating blade can easily lead to workplace injuries such as cuts.

[0007] Impact of fatigue during operation: Focusing on tool adjustment for extended periods can lead to operator fatigue, increasing the probability of errors.

[0008] (4) Skill dependence and talent gap High experience threshold: Skilled workers need years of experience to master the tool adjustment skills for complex workpieces, while novices are prone to causing batches of scrap due to improper operation.

[0009] Insufficient standardization: Different workers have different knife-setting habits, making it difficult to form a unified process standard and affecting production stability. Utility Model Content

Furthermore, the magnetic non-contact positioning, combined with a detection circuit and insulating pad, allows the operator to maintain a safe distance from the rotating tool, greatly reducing the rate of workplace accidents.

It sets a new operating standard for the industry.

[0022] Please see Figure 1-6 A manual tool adjustment and positioning device for a milling machine based on a magnetic conductive circuit includes a milling machine guide wheel reference surface 7, a milling machine guide plate reference surface 8, a conductive milling cutter 9, and a tooling body 1. A battery box 4 is installed inside the tooling body 1, and a charging port is provided on the outside of the battery box 4. Two sets of indicator lights 3 are installed inside the tooling body 1, and two sets of magnets 2 are installed inside the tooling body 1. A magnetic contact point 6 is installed inside the battery box 4, and an insulating pad 5 is provided on the outside of the magnetic contact point 6.

[0023] A nylon insulating layer is provided between the magnet contact point 6 and the magnet 2 to prevent leakage current in non-contact states. The insulation layer has a withstand voltage of >100V (safety redundancy design). Tooling body 1: Quenched and tempered 45 steel base (dimensions 255×40×30mm), surface finely ground, surface roughness Ra1.6.

[0024] Magnet 2: Heat-resistant neodymium magnets are selected and the surface is nickel-plated. The magnet 2 can form a closed magnetic circuit through the reference surface 7 of the milling machine guide wheel and the reference surface 8 of the milling machine guide plate, with a magnetic attraction force ≥180N.

[0025] Indicator 3: 3V DC power supply in series with LED indicator, indicator 3 brightness > 200cd / m², response time < 0.1s, loop resistance < 0.5Ω.

[0026] Battery Box 4: Uses a 3V DC power supply to power a closed circuit, causing the LED indicator light to illuminate.

[0027] Insulating pad 5: Separates the magnet contact point 6 from the tooling body 1.

[0028] Magnet contact point 6: Installed on one side of the fixture body 1, using a 45 steel contact block (size φ24×8mm), or Q235 steel.

[0029] The positive terminal of the battery box 4 is connected to the magnet 2 via a wire. The magnet 2 is connected in series with two indicator lights 3 via a wire. The indicator lights 3 are connected to the magnet contact point 6 via a wire. The magnet contact point 6 is connected to another magnet 2. The other magnet 2 is connected to the positive terminal of the battery box 4.

[0030] This device utilizes the principle of closed-circuit conduction to construct a conductive loop through a magnet. Its core logic is as follows: Magnetic conductive circuit: Current path: Battery box 4 positive terminal → wire → magnet contact point 6 → conductive milling cutter 9 (when in contact) → magnet 2 → wire → battery negative terminal; Magnet 2 itself is part of the conductive path Magnetic circuit design Neodymium iron boron magnets (N35 grade) form a horseshoe-shaped magnetic circuit through a magnetically conductive steel plate (such as Q235 steel), which provides strong magnetic attraction (≥18N) and also serves as a current channel.

[0031] a. When the tool is not in contact with the conductive block: When the circuit is open (resistance → ∞), the current is 0, and the light bulb goes out.

[0032] The schematic diagram of the operating conditions under the open circuit state is shown below. Figure 2 The schematic diagram for the open circuit state is shown below. Figure 3 b. When the tool contacts the conductive block: The circuit resistance drops sharply to <0.5Ω (as measured experimentally), and the current reaches 6mA (3V power supply), which is sufficient to light up the LED bulb.

[0033] See the schematic diagram of the working condition in the closed state. Figure 4 The schematic diagram of the pathway status is shown below. Figure 5 .

[0034] Working principle: Two magnets 2 are respectively attracted to the reference surface 7 of the milling machine guide wheel and the reference surface 8 of the milling machine guide plate. The two points of the guide wheel and the reference surface of the guide plate are aligned. When the conductive milling cutter 9 contacts the contact point 6 of the magnet, the current forms a circuit through "magnet 2, indicator light 3, and magnet contact point 6", triggering the LED indicator light 3 to light up (response time < 0.1s), realizing accurate judgment of the tool position.

[0035] In summary, this manual tool adjustment and positioning device for a milling machine based on a magnetic conductive circuit can significantly reduce tool adjustment errors and eliminate the problem of stepped tool marks on the copper plate through the design of the magnetic conductive circuit. Furthermore, the use of magnetic non-contact positioning, combined with the detection circuit and insulating pad 5, can ensure that the operator maintains a safe distance from the rotating tool, greatly reducing the rate of workplace accidents.

[0036] This invention transforms the traditional visual judgment method that relies on the operator's experience in tool adjustment into a precise electrical signal triggering mechanism, which greatly improves the accuracy and reliability of tool adjustment. It is especially suitable for the copper processing industry, where the requirements for high precision and high safety are extremely stringent, and sets a new operating standard for the industry.

[0037] The standardized dimensions and anti-slip texture design of the main body of this utility model tooling unify the tool adjustment benchmark, reduce the differences in tool adjustment results among different operators, and reduce the scrap rate. In addition, the design of the detection circuit and the use of a replaceable battery box avoid the wear problem of traditional dial indicator probes, greatly reducing the frequency of tool maintenance.
