Abstract

(57) [Summary] [Purpose] This relates to a grinding wheel that allows grinding fluid to be reliably supplied to the grinding point without interruption even if the grinding point moves moment by moment, such as when grinding the outer periphery of a cam. The purpose is to obtain a tool with a liquid supply function. [Structure] The grinding wheel holder 2 incorporates the grinding wheel 1 inside thereof and is fixed with a clamp bolt 3. Grinding fluid supply channels are provided inside the grindstone holder 2 and at the center of the shaft of the clamp bolt 3, respectively. . Water holes, which are flow paths for grinding fluid, are formed radially between the holder 2 and the grinding wheel 1, and a groove-shaped water ring 5 is in communication with the water hole 4. A grinding fluid flow path of the water ring 5 is bored in the circumferential direction of the outer periphery and is configured to open toward the grinding surface. As a result, grinding fluid can be constantly supplied to the grinding point to prevent clogging and seizure of the grindstone.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a grinding wheel for reliably supplying grinding fluid to a grinding point.

0002

[Conventional technology]

Figure 4 shows an example of a means for supplying grinding fluid to the outer periphery of a grinding wheel used in conventional grinding. There is one shown in FIG. In the figure, 1' is a whetstone, 6' is the outer surface of the whetstone, and 7 is a whetstone. On the workpiece, the rotation of the grinding wheel 1' attached to the grinding wheel holder causes the grinding wheel surface 6' on the outer periphery to be As a result, the workpiece 7 is ground.

0003 At this time, the grinding fluid spouted from the coolant nozzle 9 grinds only from a certain direction. Supplied to the cutting point.

0004 Another conventional example of a grinding fluid supply means is shown in FIG. In the figure 1' is a grinding wheel, and 9 is a coolant nozzle placed opposite to both sides of the grinding wheel 1'. Grinding fluid is supplied from the hole toward the grinding point 8. 7 is the work.

[0005] In this device, the coolant nozzle 9 that supplies the grinding fluid is always directed toward the grinding point. It is equipped with an NC device that controls the Grinding fluid is constantly supplied to the grinding point.

[0006]

[Problem that the idea aims to solve]

By the way, in the above-mentioned conventional method shown in FIGS. 4 and 5, once the grinding point is Even if the cutting fluid is supplied, if the grinding point moves as the machining progresses, for example, the cam In the case of peripheral grinding such as grinding, the grinding fluid cannot be supplied to the grinding point, and the grinding wheel There is a problem in which clogging and burn-in occur more easily.

[0007] In addition, in another conventional method shown in Fig. 6, grinding fluid can always be supplied to the grinding point. , the equipment is complicated and very expensive, and in addition, there is always a need to grind at the grinding point. There are some disadvantages such as the need for an NC device and its program to control the supply of liquid. There is a point.

[0008] The present invention solves the above-mentioned problems and provides a grinder that can reliably supply grinding fluid to the grinding point at all times. The purpose is to provide a tool with a cutting fluid supply function.

[0009]

[Means to solve the problem]

In order to achieve the above purpose, the tool with a grinding fluid supply function of this invention has a grinding wheel holder. It is configured so that a flow path for the grinding fluid is formed between the two when installed on the A grinding fluid supply channel that opens toward the surface and is provided inside the grinding wheel holder communicates with the flow channel. It is characterized by the fact that

0010

[Effect]

The above-mentioned tool with a grinding fluid supply function of the present invention has a grinding fluid supply function that is drilled into the grinding wheel holder from the outside. The grinding fluid supplied through the grinding fluid supply path flows between the grinding wheel and the grinding wheel holder. It flows through the channel and is supplied to the entire outer periphery of the grinding wheel surface. and the opening is directed towards the grinding surface. The grinding liquid is supplied toward the grinding point through the grinding liquid flow path. This allows grinding of the outer periphery of the cam. Even if the grinding point moves every moment due to grinding, etc., the grinding fluid is supplied to the entire area of the grinding wheel surface. The supply of grinding fluid to the grinding point is never interrupted.

[0011]

【Example】

One embodiment of the present invention will be explained below with reference to the drawings. Figure 1 shows the outside of the grindstone of the present invention. 2 is a sectional view of the same, and FIG. 3 is an explanatory diagram of the operating state. In these figures, 1 is a grinding wheel with water holes 4 drilled radially from the center toward the outer diameter. , a groove-shaped water passage ring 5 is bored in the longitudinal direction of the outer periphery and further in the circumferential direction of the outer periphery for communication. Configure it like this.

0012 2 is a whetstone holder that incorporates the whetstone 1 inside and supports it, and clamp bolt 3 It is fixed at A grinding fluid supply channel is also drilled vertically in the center of the grinding wheel holder 2. The supply path communicates with the water passage hole 4.

[0013] A hole is also drilled inside the center axis of the clamp bolt 3, and the grinding fluid supplied is connected to the grinding wheel. The internal supply path of the holder 2 passes through the center hole of the clamp bolt 3, and then the holder 2 and the abrasive The water flows through the water passage hole 4 formed by the groove provided in the stone 1 and the water passage ring 5 and reaches the outer periphery of the grinding wheel 1. It is supplied to a grinding point 8, which is a contact point between the provided grindstone surface 6 and the workpiece 7.

[0014] The grinding fluid flow path of the water ring 5 is configured to open toward the grinding surface.

[0015]

[Effect of the idea]

As described above, according to the tool with the grinding fluid supply function of the present invention, the grinding fluid is constantly supplied to the grinding fluid. Since it is possible to supply to the point, clogging of the grindstone and occurrence of seizure are prevented. This can increase machining efficiency.

[0016] In addition, the structure is simplified and the grinding fluid follows the movement of the grinding point unlike conventional equipment. Since there is no need for a dedicated control mechanism to supply this, costs can be significantly reduced.
