2. Description of the Related Art A mechanism for reciprocating an article by an air cylinder has been widely used in various technical fields. There are various commercially available air cylinders, which have been standardized to a certain extent.
The members for attaching the air cylinder and the members for attaching and sliding the table are individually designed, and there is no standardized member. Conventionally, when a linear motion guide is combined with an air cylinder, a designer has designed and combined each of the parts. However, designing from scratch requires considerable effort. Recently, pneumatic manufacturers have announced ready-made products with combined specifications, but the number of models is limited and few satisfy the designer's wishes. In addition, since it is not possible to perform additional machining on existing products, when mounting other standardized equipment (such as an air chuck) on the table surface, a separate spacer may be required due to the mounting hole position. Almost.

[0003]

Therefore, it takes a lot of design man-hours, it is difficult to repair because the parts are various, and the assembly method is also various, so that there are cases where the number of assembly steps is large. There were various problems.

The present invention has been made in view of the above circumstances, and has as its object to rationalize and streamline the design, manufacture and distribution in the field of combination drive equipment, particularly in the field of air cylinders with linear guides. The present invention preliminarily semi-standardized and / or standardized, and in particular semi-standardized and / or standardized in advance a member for mounting an air cylinder and a member for attaching and sliding a table, thereby greatly reducing the number of design steps and assembly steps, The purpose of the present invention is to easily assemble an air cylinder with a high-precision linear motion guide that is easy to repair.

[0005]

SUMMARY OF THE INVENTION The present invention is an assembly unit for an air cylinder with a linear motion guide, characterized by including a semi-standardized base member. The basic technology is to make the base a semi-standardized member, and it has a feature that it can support various types, for example, 28 types as basic specifications, with only a small amount of processing of the unit semi-standardized member.

[0006] By forming the semi-standardized base member as a long body having a plane in which a fitting groove is formed in a longitudinal direction,
The present invention is a linear motion guide, commercially available products such as air cylinders, semi-standard members such as aluminum base and other standard components,
An assembly unit for an air cylinder with a linear motion guide, which can be completed by a combination system called a unit system, can be provided. The fitting grooves formed in the longitudinal direction may be two upper and lower surfaces or four upper, lower, left and right surfaces so as to correspond to various types. The fitting groove is a groove standardized so that the linear guide can be mounted with high accuracy.

The semi-standard member is preferably a long body of aluminum material from the viewpoint of ease of processing. Since an aluminum material can be extruded, a long material having a rectangular cross section can be easily obtained. By further machining the aluminum material, a base member having a fitting groove with high dimensional accuracy can be obtained.
The fitting groove having high dimensional accuracy is premised on mounting the linear motion guide and the air cylinder with high accuracy. That is, a most preferred aspect of the present invention is an air cylinder with a linear motion guide, comprising a semi-standardized base member which is a long body of aluminum material having a rectangular cross section having a plane in which a fitting groove is formed in a longitudinal direction. Assembly unit. The aluminum base is extruded with a standardized mold material, so that additional processing such as drilling is easy. A standardized groove is provided so that the linear motion guide can be accurately mounted. Since the height is standardized, a linear motion guide mounted on an aluminum base can be used in parallel with a free width.

The present invention further includes a linear motion guide comprising a slider and a rail, and the present invention includes a semi-standardized base member and a linear motion guide comprising a slider and a rail. It is a component unit. The linear motion guide is a linear motion guide assembly comprising a slider and a semi-standardized rail member fitted and mounted in the fitting groove. When the linear motion guide is fitted into the fitting groove of the base member and mounted, the axis of the base member coincides with the axis of the linear motion guide, so that centering during assembly becomes unnecessary, and parallelism and dimensional accuracy , An assembly having a high height is obtained.

[0009] The invention further includes a cylinder bracket for attaching a cylinder of an air cylinder to the base in parallel with the base, a joint holder and a joint connector for connecting a piston rod of the air cylinder to a table plate, and a table plate attached to a slider of a linear guide. The present invention provides a semi-standardized base member, a linear motion guide comprising a slider and a rail, a cylinder bracket for attaching an air cylinder cylinder to a base in parallel with the base, a joint holder for connecting an air cylinder piston rod to a table plate, and An assembly unit for an air cylinder with a linear guide, including a joint connector and a table plate attached to a slider of the linear guide. By attaching a table plate to the slider of the linear motion guide and connecting a piston rod of an air cylinder with a joint holder and a joint connector, a commercially available air cylinder can be attached to the base member with high precision while maintaining parallelism. The table plate on the movement guide can be reciprocated smoothly while maintaining parallelism with high precision to the base member.

[0010] The present invention further includes a stopper block, a shock absorber, and a shock holder for mounting the shock absorber to a base. Cylinder bracket for attaching the cylinder of the air cylinder to the base in parallel, joint holder and joint connector for connecting the piston rod of the air cylinder to the table plate, table plate to be attached to the linear motion guide slider, stopper block to be attached to the table plate, shock absorber And an assembly unit for an air cylinder with a linear motion guide, comprising a shock holder for attaching the shock absorber to a base. In addition to the above points, a stopper block can be attached to the table plate and a commercially available shock absorber can be attached to the base member by the shock holder, so that the shock can be absorbed at both ends of the reciprocating motion of the table plate.

The present invention is a method for manufacturing an air cylinder with a linear motion guide of any form using an air cylinder of any form, characterized by using the assembly unit for an air cylinder with a linear motion guide. It is a method.
The present invention develops a standard component and a semi-standard member which can correspond to a linear motion guide, an air cylinder, etc., and registers them as application software for CAD. It is possible to easily complete the drawings of the air cylinder with the linear motion guide of various specifications by writing the desired overall length of the member, the mounting hole position, the type, and the like, and freely moving and combining commercially available products and standard parts. This can greatly reduce the number of design steps. We also believe that setting the price of application software at a low price can contribute to the reduction of design costs.

The parts for mounting the air cylinder are as follows:
The standards conform to the products of each air cylinder manufacturer. For this reason, the designer can always adopt a manufacturer product that is familiar to him, so that he / she can design with confidence in that respect. When a user manufactures an air cylinder with a linear guide, most of the parts are standardized and semi-standardized, and the parts and members are sold together. Production man-hours can be reduced. Also, semi-standard members can be easily processed because they are only cut and drilled. In addition, even if it is difficult to process and assemble in-house, it is possible to set up a manufacturing place in each area to act for the user on behalf of the user, and the user hands the drawings designed by himself to the manufacturing agency. This makes it possible to obtain a finished product of the original air cylinder with a linear motion guide required by the user.

[0013] The manufacturing method of the present invention includes a mode in which a user himself / herself designs what he / she desires and manufactures it by a local manufacturing agent factory and manufactures it as a finished product. If the price of the finished product is high, it is meaningless, and the whole system becomes meaningless. Therefore, it depends on how to set a price that can be convinced and purchased by the user with peace of mind, and that is competitive with existing products of the same specifications of other manufacturers. In order to solve the problem, there is a problem in that the price of a commercial product such as a linear motion guide and an air cylinder, which accounts for most of the price of the air cylinder with a linear motion guide, does not affect the product price.

According to the conventional method, the number of manufacturing sites is limited to one. Therefore, a commercial product manufactured by a commercial product maker is made into a product by purchasing and assembling the product via a dealer A near the manufacturing site and a dealer. One of the stores distributed in each region, B, sold to users via the stores. In that case, if the shipping price of a commercial product maker is 1, and the margin for distribution and management is 10%,
A. The amount sold from the dealer to the factory is 1 ÷ 0.9
$ 1.11; The amount sold to the dealer is 1.11 ÷ 0.9 ≒ 1.23.
The amount sold from the dealer to the user is 1.23 ÷
0.9 ≒ 1.36.

In the case of the method using the unit of the present invention, the manufacturing agent factories can be dispersed in each region. Distributors and B. The dealer can be the same. Therefore, in exchange of a commercial product between the dealer and the manufacturing agent factory, supply can be performed, and no margin is generated. That is, the amount sold from the store to the user, 1 ÷ 0.9 ≒ 1.11
And a price difference of as much as 25 points occurs in comparison with the conventional method. Basically, in this method, since a commercial product is provided to the manufacturing agent factory with supply, there is no administration cost at the manufacturing agent factory, and thus the cost can be reduced.
Moreover, it is a system that can be introduced immediately without affecting the existing distribution system. As an advantage on the user side of this method, since the price of commercial products is always the same as the purchase price, by specifying the price of standard parts to the user, it is possible to understand the outline of the processing and assembly costs at the manufacturing agency factory,
It is easy to determine whether to assemble in-house or request manufacturing. In this case, the sales are mainly performed by the retailer, but the retailer can also determine the combination of commercially available products by installing a product from a manufacturer that is good at the retailer. Can be completed and sold.

The present invention is also an air cylinder with a linear motion guide obtained by the above method.

[0017]

Next, embodiments of the present invention will be described with reference to the drawings. 1 is an assembly unit for a linear motion guide table according to one embodiment of the present invention, FIG. 2 is a linear motion guide table assembly of the unit of FIG. 1, and FIGS. 3 to 7 are perspective views of various embodiments of the present invention. is there.

In FIG. 1, reference numeral 1 denotes a base member which is a long aluminum material having a rectangular cross section. Since the base member 1 is an aluminum material, it can be easily formed into a long material having the same cross-sectional shape by extrusion. Then, after the molding, the fitting groove 1a is cut on the side face by machining, and finished with high dimensional accuracy. The number of the fitting grooves 1a may be any number from 1 to 4, but it is most preferable to form 4 fitting grooves, since the degree of freedom of assembly is increased.

Reference numeral 2 denotes a linear guide comprising a rail 2a and a slider 2b, and the slider 2b slides on the rail 2a. The outer dimensions of the rail 2a are the same as the fitting groove 1a of the base member 1, and when fitted together, the axes of the base member 1 and the rail 1a coincide.

Since the rail 2a is fitted for positioning and is not fixedly attached thereto, the connection between the rail 2a and the base member 1 is made by machining a screw hole and fastening with a bolt. Alternatively, fasten with bolts and nuts in the through holes.

Reference numeral 3 denotes air cylinders, which are commercially available. At the time of this application, a number of air cylinders with a standardized output and dimensions are commercially available from several manufacturers.

Reference numeral 4 denotes a cylinder bracket for mounting the cylinder 3a of the commercially available air cylinder 3 to the base member 1. The cylinder bracket 4 is L-shaped when viewed from the side, and is mounted between the head of the cylinder 3a and the side of the base member 1 with several bolts or nuts.

5 is a piston rod 3b of the air cylinder 3.
Is a joint holder attached to a table plate 7 described later.
This is a joint connector to be attached to The joint connector 6 is screwed into the piston rod 3b, and the groove is sandwiched by the fork 5b of the joint holder 5.
The base 5a of the joint holder 5 is fastened to the table plate 7 with bolts.

Reference numeral 7 denotes a table plate which is fastened by bolts to the slider 2b of the linear motion guide.
Reference numeral 8 denotes a stopper block, which is fastened to the lower surface of the table plate 7 with bolts. Reference numeral 9 denotes a shock holder. A commercially available shock absorber 10 is screwed into the female screw hole 9b, and the coupling projection 9a is aligned with the fitting groove 1 of the base member 1 and fastened with bolts.

FIG. 2 shows an air cylinder A with a linear guide in which an assembly composed of the above-described members is combined. In FIG. 3, reference numeral 11 denotes an end plate. When the cylinder bottom of the air cylinder 3 is fixed to the base member 1 by using the end plate, even if the cylinder 3 is long, accurate parallelism can be maintained. The table plate 7 can be slid.

According to this embodiment, there are the following advantages. Since each part is machined with high precision and the main parts are connected by bolts that also serve as positioning pins, high-precision positioning is possible and the parallelism between the linear guide and the air cylinder can be easily obtained. Therefore, even if a user combines parts, a highly accurate table type air cylinder with a guide can be completed.

The air cylinders and shock absorbers on the market are not interchangeable because they are the dimensions of each manufacturer's standard, but by changing the hole processing (hole position, hole diameter) of the cylinder bracket, shock holder and end plate. It can correspond to any commercial products.

Since the aluminum base, which is rich in workability, is used as the basic member, the overall length desired by the user can be obtained. Also, the mounting hole position can be determined and processed according to the device to be mounted.

Since disassembly and assembly are easy, the life and repairability of commercially available products (air cylinders, shock absorbers) against failures are good, and the maintainability is also good.

Optional and standard commercial products (linear motion guides, air cylinders) that can be mounted can also be mounted if the mounting matches. Thereby, the variation of the assembly can be abundant.

It is possible to change the mounting position of the air cylinder on the aluminum base from side to side with the same parts.

Next, another embodiment of the present invention will be described. The embodiment shown in FIG. 4 is an example using an air cylinder 3 with an air cushion. The base member 1, the table plate 7, the joint holder 5, the joint connector 6, and the cylinder bracket 4 are used together with the linear guide 2 and the air cylinder 3. The shock absorber 10 and the shock holder 9 are not required.

The embodiment shown in FIG. 5 is an example in which the work is moved out of the range of the base member 1 by extending the table plate 7. At this time, the shock absorber 10 for absorbing the shock at the table forward end can be mounted on a surface of the base member 1 symmetrical to the air cylinder mounting surface. In the figure, the shock absorber 10 for absorbing the shock at the retreating end of the table is also mounted on the base member 1 on the symmetrical surface of the air cylinder mounting surface.

The embodiment shown in FIG. 6 is an example in which an extension plate 11 (extension plate) is mounted on the table plate 7, and the work can be moved out of the range of the base member 1.

The embodiment shown in FIG. 7 is an example in which a horizontally long table plate 7 is guided by combining two base members 1 in parallel, and can correspond to a wide work.

The embodiment shown in FIG. 8 is an example in which the rail 2a of the base member 1 and the linear guide 2 is elongated, and two bearings of the linear guide 2 can be mounted. This makes it possible to improve the moment resistance.
