Description

The present invention relates to various bases used in lathes and other various machine tools, work tables for processing and assembling various mechanical devices, and partial structures of various mechanical devices, and the like. The present invention relates to a slide mechanism that slides in a straight line direction in a non-separated close state, provided to slide in a straight line direction in a state.

Various bases are adapted and used for lathes and other various machine tools, work tables for machining and assembly of various machine devices, and partial structures of various machine devices. In addition, the mutual surfaces of the opposite bases (usually called a board, a stand, a stage, a base, a plate, etc., variously depending on the installation location, application, etc.) are in close contact with the non-separated (configuration that cannot be separated and divided). The slide mechanism provided to slide in a straight line is often used.

Conventionally, as the most general examples, there are those shown in FIGS. 4 to 6, and those similar to these are often used.

The slide mechanism (S1) (conventional example 1) shown in FIG. 4 integrally forms a protrusion with a convex cross section as a guide bar C1 on the slide surface a1 of the base A1, while the guide bar C1 on the slide surface b1 of the base B1. A guide groove D1 having an inverted convex cross section is formed, and the guide bar C1 is slidably and tightly fitted into the guide groove D1, so that the bases A1 and B1 are in a state where the slide surfaces a1 and b1 are not separated. Is slidable in a straight line direction.

In the slide mechanism (S2) (conventional example 2) shown in FIG. 5, a protruding bar having a trapezoidal section is integrally formed as a guide bar C2 on the slide surface a2 of the base A2, while the guide bar C2 is provided on the slide surface b2 of the base B2. A guide groove D2 having an inverted trapezoidal cross section is formed, and the guide bar C2 is slidably and tightly fitted into the guide groove D2. The bases A2 and B2 are aligned in a straight line with the slide surfaces a2 and b2 being unseparated. It is slidable in the direction.

The slide mechanism (S3) (conventional example 3) shown in FIG. 6 is provided with two guide bars C3 each having a U-shaped cross section, while the cross-section of the cross-section is extended over the slide surfaces a3 and b3 in close contact with the bases A3 and B3. A guide groove D3 having a U-shaped cross-section for inserting and inserting the guide bar C3 in a slidable and tight manner is formed in parallel, and the guide bar C3 is slidably and closely fitted in the guide groove D3 to slide. The bases A3 and B3 are slidable in a straight line direction with the surfaces a3 and b3 in an unseparated state.

However, in order to manufacture and provide the slide mechanism as in the conventional example with high precision and high performance as required by the user, first, an expensive precision processing machine device that performs precision processing with the required high precision is provided. It necessitates a high equipment cost because it is necessary, requires a human cost to secure a highly skilled processing engineer to operate it, and also requires a lot of labor and time to manufacture and process with them Therefore, there is a big problem that the cost is extremely high.

In addition, as a matter of course, the mutual slide surfaces of the bases are manufactured and processed into precise planes, and particularly when the guide bars and guide grooves for guiding the close sliding between the bases are precisely manufactured, the guide bars and the guide grooves are formed. Because it has “corners” and “surfaces” in its cross-sectional shape, it is difficult to precisely manufacture and process each corner and surfaces so that they can be slidably fitted with high precision. There was the biggest problem.
Therefore, the present invention provides a slide mechanism provided with a guide bar and a guide circular groove (guide semicircular groove relative to each base) having a circular cross-sectional shape that facilitates precision manufacturing of the guide bar and the guide groove. By doing so, the above-described conventional problems are effectively solved.

According to the first aspect of the present invention, a concave surface having a U-shaped cross section composed of left and right side surfaces and an upper surface is formed linearly on one slide surface with the relative surface of the opposite base as a slide surface, and the concave portion on the other slide surface is formed. A U-shaped cross section consisting of left and right side surfaces and an upper surface is formed linearly at a position facing the groove,

The convex groove is fitted into the concave groove, and both bases are slidable in a straight line direction with the concave groove and the convex guide.

While two straight bar bars with a circular cross section are provided separately,

A semicircular cross-sectional shape for fitting a semi-circular section of the round bar-like guide bar tightly and slidably to the left and right side surfaces of both bases facing each other by fitting the concave groove and the ridge. By forming circular guide grooves relative to each other, two circular guide grooves that match two pairs of semicircular guide grooves are formed in parallel, and the circular bar guide bar is fitted in each circular guide groove. It is prepared by inserting,

Therefore, the opposite bases are provided in a non-separated state in the vertical direction, and the opposite bases are provided in a non-separable manner so as to be slidable in a straight line direction with a linear guide of a round bar guide bar and a circular guide groove. The problem is solved by a sliding mechanism that slides in a straight line direction in close contact with each other.

In the present invention, a mechanism in which a ridge is fitted into the groove and both bases are slidable in a straight line direction by the guide of the groove and the ridge, at first glance, looks similar to the conventional one. In this case, since it is sufficient that this part can be slid as a part of the overall configuration of both bases, the accuracy is not so necessary. There are advantages that do not exist.

Thus, the configuration of the present invention is characterized in that each of the round bar-shaped guide bars is fitted tightly and slidably into two parallel circular guide grooves provided across both bases. The two guides are characterized by the fact that both bases are slid in a straight line direction with high precision, but this circular guide groove and round bar guide bar are manufactured and processed with high precision and high precision. Since it is only simple circular hole processing and round bar processing to be fitted in, it can be easily done in a short time without requiring any skill in ordinary machinery and equipment. Compared to manufacturing and processing of “corners” and “planes” that are the issues of high accuracy and high precision, the extremely excellent effect that can be manufactured and processed much more easily and at low cost is there.
