JPH0248155A - Diamond polisher for ice skate edge - Google Patents

Abstract

PURPOSE:To obtain the small sized portable edge polisher capable of performing the rapid and accurate polishing by forming a polished surface configuration adapted for an arbitrary edge groove configuration on a small piece made of plastic or the like and sticking, on the above surface, a diamond or the like with adhesive or the like. CONSTITUTION:On a small piece, there is formed a projecting surface configuration 2 adapted for the sectional cinfiguration of an ice skate edge or the lie. A polishing body 3 is composed of the small piece on which high hardness abrasive such as diamond is rigidly bonded through an electrodeposition process or using, plastic, adhesive or the like. In the title polisher, there is housed a motor 4 or solenoid vibrator 5 through a mechanism for reciprocating the mounted polishing body 3 and, on the upper part thereof, there is mounted an inducing groove mechanism which can be adjusted according to the thickness of the ice skate edge. Further, the polishing surface 2 of the polishing body 3 can be changed in the desired configuration and the induced groove mechanism can be exchanged in the desired configuration.

Description

[Detailed Description of the Invention] [1] Industrial Application Field (a) Ice Skate Edge polishing machine is mainly intended for personal use, but can also be used for commercial use.

(b) It can be widely used as a polishing machine for repairing cutting tools (bites) in machine tool factories, etc. [2] The necessity of polishing conventional ice skate edges.

When the edges of an ice skate become worn and rounded, the skate will skid sideways on the ice and will no longer be able to glide smoothly.

In addition, the edge may differ slightly depending on the purpose of use (compar tree figure and free skating in figure skating, forward and goalie in ice hockey, etc.), outside temperature, ice temperature, skater's technique, weight, ice hardness, etc. sharpness is required.

There are two methods for polishing ice skate edges:

[Hand-sharpening] A cylindrical oil whetstone (10 to 30 mm in thickness and about 50 mm in length) is attached to the groove (1) of the ice skate edge and slid on it.In this case, the oil whetstone will wear out locally. ,
Polishing the edges evenly and evenly requires highly skilled and highly skilled techniques and takes a long time.
Some jigs are available in which a piece of metal or wood is processed into a U-shape and the edge is sandwiched between the edges and the whetstone, but the grindstone is still subject to severe wear and difficulty.

[Mechanical sharpening] This is a polishing machine that is a modified tabletop grinder.It is not suitable for personal use, is a stationary type and is not portable, and is used exclusively for commercial use.

As shown in Figure 3, the grinding wheel disc (6) is installed horizontally, the outer periphery (7) of the grinding wheel is processed into a convex arc surface, the ice skate edge is fixed to a fixture, and the grinder is manually operated. (7) The finished surface depends on the roundness of the outer circumference of the grinder, the elasticity of the suppression of the ice skate edge, and the unevenness of the sliding feed rate as shown in Figure 4. As shown in (8), it is easy to create waves and form a so-called chiseled surface, and if the sliding movement stops even for a moment, the grinder will dig in, as shown in (9). Since the original pattern is lost, it requires more advanced technique and skill than manual sharpening.

[3] Problems to be Solved by the Invention As explained in [2], manual sharpening requires advanced technology and skill, and a long time for sharpening, and mechanical sharpening requires even more sophisticated technology. It requires skill and skill, is not portable, and is expensive, making it unsuitable for personal use.

Therefore, we developed a revolutionary ice skate that is small and convenient for ice skaters to sharpen quickly and accurately by anyone, anywhere, without requiring advanced technology or skill. It would be great if we could provide you with an edge polishing machine.

Measures to solve the problem 1 In order to sharpen smoothly like manual sharpening without creating chiseling marks or digging like mechanical sharpening, we use a reciprocating bar-shaped polishing body instead of a disc-shaped rotating body. I changed it to a dynamic polisher.

2. In order to obtain an abrasive body that does not easily cause local abrasion and has excellent wear resistance, like an oil whetstone used in manual sharpening, a small piece of metal or plastic deck is coated with an arbitrary ice skate edge groove shape. A so-called diamond whetstone was used, in which a suitable abrasive surface shape was formed, and high-hardness abrasive grains such as diamond were fixed to the surface by electroplating, plastic, adhesive, or the like. However, the term "diamond whetstone" mentioned here is a general term that includes different materials that are used for similar purposes.

3. In order for anyone to sharpen easily and accurately,
Ice Skate Edge [4] Since the polishing body must always be in proper contact with the groove and be able to slide, a guiding groove for the Ice Skate Edge is constructed in the main body of the polishing machine, and the Ice Skate Edge is placed in the groove. Equipped with a function to adjust the groove width according to the wall thickness.

4. It is small and portable, and does not require any special fixing jigs, so it can be used anywhere.
I summarized it as a grasp-and-use type.

Effects of the Invention Regarding the scope of the patent claim (b), the effects are noted in detail: In machine tool factories, etc., a processing method is often used in which the shape of the cutting edge of a cutting tool is copied onto a product. In such cases, the present invention is very effective.

That is, if a small piece of abrasive body (3) that copies the shape of the product is prepared and prepared, repair management of the cutting edge of the cutting tool can be easily performed.

[Brief explanation of the drawing]

Figure 1 is an explanatory diagram of the basic principle of this invention. FIG. 21 shows, in approximately the original size, the ice skate edge attached to the polishing machine in this embodiment. Figure 3 is a schematic diagram of a conventional stationary ice skate edge polishing machine. Figure 41 shows an example of polishing marks when an ice skate edge is polished using the polisher shown in Figure 3. Figure 5 is an exploded view of the polishing machine according to the embodiment of the present invention. To attach (3) to (11) in the figure, insert the spring (12) into the dovetail groove of (11) from the end face in the elongated direction while pressing down the end of the spring (12) with the end face of (3). To remove it, insert the detachable lever (13) (special tool) into the lever insertion groove on the end face of (3), push down the spring (12), and pull it out. In addition, sets of several types of edge guide groove width adjustment shims (14) with different thicknesses are prepared in advance and replaced according to the edge.
