Description

The invention relates to the field of mechanical engineering, namely to the basic components for linear systems of movement, and can be used to install various types of guides for linear movement, as well as various types of drive mechanisms.

The following technical solutions are known from the prior art.

Known guide profile (US patent No. 5445045, 08/29/1995), having a concave part, while the drive source is installed in a concave section. The slider is installed in the concave section, while the slider moves along the concave part. The cover is used to cover the concave part of the profile. The profile also includes grooves made in the respective outer sides, which have T-shaped cross sections. The grooves are defined in the longitudinal direction of the profile so as to be identical in structure to each other. The drive mechanisms can be connected to each other by means of grooves in such a way as to assemble the drive having the desired configuration, thereby making it possible to place the drive mechanism on the production line in the factory.

A linear displacement module is also known (US patent No. 5131125, 07/21/1992), including a housing formed by a profile, the lower surface of which is provided with grooves, the profile includes a lower base constituting a supporting surface corresponding to the maximum width of the guided body, the length of the lower base has a longitudinal hole, allowing positioning of the connecting strip.

The closest analogue to the proposed technical solution is the profile (US patent No. 5661945, 02.09.1997), made in the form of a beam to support a moving load, can be made of aluminum profiles or other materials. The symmetrical U-shaped extruded profile has parallel rods extending downward and a connecting element between the rods. Between the connecting element and the lower part of the profile, guides and drive elements are mounted in several planes. On the reverse side of the profile are grooves of various types.

The disadvantages of the known solutions are the complexity of design and operation, the need to use two or more different profiles for the implementation of a protected housing-caliper, as well as the lack of versatility for various types of installed guides and drives.

When developing the proposed technical solution, the task was to create a compact and lightweight tool for designing linear motion systems that would accelerate the assembly process, was universal for various types of mechanisms and linear guiding movements, and did not require labor costs in production.

The technical result of the claimed technical solution is to provide versatility for different types of mechanisms and linear guides of machine tools, expanding functionality due to the possibility of installing different guides for linear movement and components of various drive mechanisms in the same profile, as well as providing the possibility of fastening the profile itself to various structural elements of automated control systems.

The specified technical result is achieved due to the fact that a profile has been created for components of linear displacement systems in automated control systems, including two side and end walls forming a U-shaped cavity, inside of which two symmetrically made on the side walls of the profile at the joints of the side and end walls grooves with sections of an arcuate shape with the transition of one end of the arc into an element of a trapezoidal open shape, in the central part of each side wall inside the U-shaped cavity There are grooves with keyhole-shaped sections, rectangular grooves are made at the ends of the side walls inside the U-shaped cavity, two stepped protrusions are made along the edges of the end wall inside the U-shaped cavity, each of which has a keyhole-shaped groove in the central part of the end wall inside the U-shaped cavity has a recess with a rectangular cross-section, inside which two protrusions are made, two grooves of widths are symmetrically made at the ends of the end wall on the outside of the profile d 2 mm and a width of 16 mm, the projections 5 with equal spacing therebetween on the side walls on the outside on the outer side of the profile has channels formed in the central portion of the end wall.

The claimed technical solution relates to a profile made of aluminum alloy by extrusion and used as a universal protected case-support for light machines and linear movement systems in automated control systems.

The design of the profile allows you to install various guides for linear movement in it (round ∅ = 8 ÷ 12 mm, rail width from 8 mm to 25 mm), use different types of drive mechanisms (gear rack M up to 3 m, trapezoidal screw (∅ = 8 ÷ 25 mm), ballscrew (∅ = 8 ÷ 25 mm), toothed belt with a width of up to 40 mm) and corrugated protection, which ensures its versatility.

In the grooves with sections of an arcuate shape with the transition of one end of the arc into an element of trapezoidal open shape, made on the side walls of the profile in the area of the joints of the side and end walls, round guides are inserted.

On the stepped protrusions made at the ends of the end wall on the inner side of the profile, rail guides are installed, which are fastened by drilling and cutting metric threads in the profile. The groove, in turn, performs the centering function for the guide rail mounting holes. From the end in the open hole, made in the form of a keyhole, a thread is cut for attaching the end plate or attaching the profile to the plane.

By means of keyhole-shaped grooves made in the central part of the side walls on the inside of the profile, the profile is fastened to the caliper plates of the structures and planar parts.

The grooves formed by the protrusions made on the end wall on the outer surface of the profile provide fastening of the profile itself, as well as fastening to the profile of other structural elements of automated control systems in various variations, which also ensures the universality of the proposed technical solution.

Corrugated protection in the form of a fabric tape impregnated with a rubber compound and assembled into an accordion with intermediate plastic ribs for stiffness is inserted into grooves with rectangular sections at the lower ends of the side walls inside the U-shaped cavity, which protects the internal mechanisms from dust, dirt, and cutting waste and creates an aesthetic look of a support.

Due to the location of installation sites in the profile on the side and end walls, each element is based in the profile along two or more contact planes, which ensures the most accurate basing.

Further, the technical solution is illustrated by reference to the drawings, which show the following:

The proposed solution relates to a universal profile made of aluminum alloy by extrusion, and contains two side walls (1) and one end wall (2) forming a U-shaped cavity for placement of components of linear displacement systems in it.

Inside the U-shaped cavity on the side walls (1) of the profile in the area of the joints of the side (1) and end (2) walls, two grooves (3) with arc-shaped sections are symmetrically made with the transition of one end of the arc into an element of trapezoidal open shape. Round guides (14) with a diameter cross section ∅ = 8 mm or 12 mm are inserted into the grooves (3). Performing a groove with a cross-section of such a shape ensures the absence of additional fastener parts in the guide rail fastening, exact guiding of the guide without alignment and installation speed.

In the central part of each side wall (1) inside the U-shaped cavity, grooves are made with sections in the shape of a keyhole (4) (formed by a symmetrical arc relative to the horizontal axis with straight lines extending from its ends with transition to a trapezoidal shape), designed to fasten the profile to edges of other profile parts and planar parts. Making a keyhole groove is a technological condition for making holes up to 10 mm in an extruded profile.

At the ends of the side walls (1), grooves with rectangular sections (5) are made inside the U-shaped cavity. Corrugated protection (15) is inserted into the grooves (5) in the form of a fabric tape impregnated with a rubber compound and assembled in an accordion with intermediate plastic ribs for stiffness, which protects internal mechanisms from dust, dirt, cut waste and creates an aesthetic appearance of the caliper.

Two stepped protrusions (6) are made along the edges of the end wall inside the U-shaped cavity, each of which has a groove with a keyhole-shaped cross section (7). On the stepped protrusions (6) made at the ends of the end wall (2), rail guides (18) are installed on the inside of the profile. Through the grooves with cross sections in the shape of a keyhole (7), the profile is fastened to the caliper plates of the structures and planar parts.

In the central part of the end wall inside the U-shaped cavity between two stepped protrusions (6), a recess is made with a rectangular section (8), inside of which there are two protrusions (9) with the formation of space for installing various drive mechanisms: a gear rack (16, 17 ) (M to 1.5), toothed belt (19) (up to 40 mm wide), ball screw (20) (∅ = 8 ÷ 20 mm). These parts are mounted between the end plates installed at the ends of the profile, between the end walls of the profile and they have a place inside the U-shaped cavity of the profile behind the corrugated protection (15).

Channels open from one edge on the outside of the side walls (1) of the profile are designed for fastening interprofile walls of plywood or MDF up to 16 mm, sheet plastic 2-4 mm, which allows you to assemble closed cases, make intermediate walls in the structure, reinforcing it thereby, use the walls as design workstations, etc. In particular, a profile of an aluminum table with a T-slot is inserted there for use as a desktop in CNC machines.

Two grooves 2 mm wide (10) and 16 mm wide (11) are symmetrically made at the ends of the end wall on the outer surface of the profile, 5 protrusions (13) are made in the central part of the end wall at equal distances from each other. The grooves on the end wall on the outside of the profile are designed for fastening the profile itself in various variations, as well as fastening other structural elements of automated control systems to the profile.

Due to the location of installation sites in the profile on the side and end walls, each element (round guides, rail guides, toothed rack, corrugated protection) is based in the profile along 2 or more contact planes, which ensures the most accurate basing.

The proposed technical solution can be implemented in the form of two more profiles that differ in size, retaining all the principles and ideas of the described profile.
