Abstract

By applying electroless plating to a driver bit that is compounded with diamond, a non-slip member having a hard portion that prevents cam-out and improves durability is provided. [Solution] Diamond particles 1 are fixed uniformly in the plating film by applying diamond composite electroless plating to the surface of the driver bit. These diamond particles 1 bite into the mating material, suppressing slippage and preventing cam-out. In addition, durability can be improved by covering the surface with a hard material.

Description

[Technical field]

[0001] The present invention relates to a component with an anti-slip coating, for example, a component that can be fixed while being pressed against a screw by attaching an anti-slip coating to the engagement surface between an electric screwdriver bit and a screw. [Background technology]

[0002] For example, when an electric screwdriver is subjected to excessive torque or impact, the tip of the bit or the groove of the screw can become deformed, rendering it unusable. If the damage is severe, the screw cannot be tightened or loosened and cannot be repaired. In addition, defects in the bit or screw can cause gaps in the engagement area, preventing the tightening force from being transmitted properly, leading to damage or deformation.

[0003] Furthermore, if a defective screw or a defective driver is used when tightening a screw, the fit will be poor and the screw may come loose immediately no matter how many times it is tightened.

[0004] With a magnetic screwdriver, it is possible to attach steel screws to the tip in advance for use, but this is not possible with stainless steel screws, which can result in reduced work efficiency.

[0005] In order to solve such problems, methods have been disclosed in which the tip shape of the bit or the groove shape of the screw is made less slippery, and methods have also been disclosed in which particles are fixed to the tip of the bit to prevent slipping. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication 2001-300860 [Patent Document 2] Special Publication No. 1994-15148 Summary of the Invention [Problem to be solved by the invention]

[0007] In order to make the tip of the bit or the groove of the screw less slippery, it is necessary to make the shape complicated, which results in a very expensive component. Furthermore, when excessive torque or impact is applied, the tip of the bit or the groove of the screw may become deformed, making it unusable.

[0008] In the conventional technology disclosed in Patent Document 2, the anti-slip material is fused by brazing, but the anti-slip material is unevenly fixed, which reduces the contact area with the mating material and may not be effective enough. Also, the brazing temperature is high, which may cause the material to become dull. [Means for solving the problem]

[0009] The present invention is characterized by the fact that diamond particles are arranged uniformly and fixed to the surface of a driver bit or screw by applying diamond composite electroless plating to the surface. Effect of the Invention

[0010] In this invention, electroless plating with a uniform thickness is used as a method for fixing diamond particles to a plating film. This allows the diamond particles to be evenly arranged and fixed on the surface of the driver bit or screw, making it possible to increase the contact surface with the mating material. With an increased contact surface, the diamond bites into the mating material, suppressing slippage and preventing cam-out, improving work efficiency.

[0011] Even in the case of stainless steel screws, the screw can be attracted to the tip of the driver bit, allowing for efficient tightening work.

[0012] By adhering diamond particles to the entire screw, the diamonds bite into the mating material, preventing loosening.

[0013] In addition, by covering the components with a hard plating film, deformation during use is reduced and durability is improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] By using diamond particles as an anti-slip material and electroless plating to adhere them, we have improved durability, prevented cam-out, and improved work efficiency. EXAMPLES

[0016] FIG. 1 is an explanatory diagram of the first embodiment, in which 1 is a diamond and 2 is the tip of a driver bit.

[0017] Diamond composite nickel plating solution was prepared by adding 8-12μm sized diamonds to Top Nicoron LPH-LF electroless nickel plating solution manufactured by Okuno Chemical Industries Co., Ltd. Diamonds were dispersed in advance by adding an appropriate amount of dispersant.

[0018] Using this diamond composite nickel plating solution, a driver bit was plated for one hour in the usual manner. The plating thickness was 15 μm, and the diamond content of the plated surface was 50%.

[0019] The plastic bottles were filled with water and weighted at 400g, 500g, 1000g, and 1500g. A stainless steel Phillips head screw was fixed to the cap of the plastic bottle, and a driver bit was inserted into the screw and then lifted upward to see if the plastic bottle would rise with the screw or if it would come off and fall. [Table 1]

[0020] As shown in Table 1, the bit without diamond composite plating could lift 400g, but could not lift more than 500g. In contrast, the bit with diamond composite plating could lift up to 1500g, demonstrating good bite.

[0021] By using a bit that has been treated with diamond composite plating in this way, it is possible to fasten a screw onto a vertical surface while holding the screw in the bit, even in the case of a SUS screw. In addition, the anti-slip effect prevents the screw from coming out even when using an electric screwdriver, and also prevents damage to the bit and screw. EXAMPLES

[0022] Except for using Nimden KHN manufactured by Uemura Kogyo Co., Ltd. as the electroless nickel plating solution, the SUS screw was subjected to a diamond composite plating treatment in the same manner as in Example 1. However, the grain sizes of the diamonds used were 1-5 μm and 3-8 μm, respectively.

[0023] Using this diamond composite nickel plating solution, a SUS screw was plated for 30 minutes in the usual manner. The plating thickness was 7 μm, and the diamond content of the plated surface was 44% when 1-3 μm diamonds were used, and 50% when 3-8 μm diamonds were used.

[0024] A total of three types of screws, an existing SUS screw and two types of screws that had been treated with the diamond composite plating, were prepared and tightened into the screw holes with a torque of 23.5 mN-m. These were loosened while gradually increasing the torque in increments of 0.0 mN-m to 0.5 mN-m, and the torque values ​​at the point where the screws could be turned were compared. [Table 2]

[0025] As shown in Table 2, when loosening the screw, the diamond composite plated screw exhibited a torque value 1.5 times higher than that of the existing screw without diamond. In this way, the diamond composite plating treatment has improved the screw loosening prevention effect. [Industrial Applicability]

[0026] By applying diamond composite plating to components to provide anti-slip properties in this way, the screw bite can be improved, improving work efficiency and contributing to increased production efficiency. Also, just as diamond-tipped screws improve the prevention of loosening by biting into the mating material, it is expected that this method will be applied to joints that are prone to loosening due to vibration, etc. [Explanation of symbols]
