Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pneumatic system with a fixed piston rod;
It relates to a linear drive with a hydraulically or electrically actuated reciprocating cylinder.

In this case, a longitudinally guided movable cylinder
Support and drive in a variable-stroke transmission, which converts the relative movement between the cylinder and the longitudinal guide into a linearly movable driver;
transmit this motion.

In known types of linear drives, the driver is actuated pneumatically or hydraulically or electrically. Its drive is performed by a reciprocating cylinder, which is fixed to a linear drive. Connected to the end of the movable piston rod is a stroke change or amplification transmission which doubles the stroke of the piston and transmits it to the driver.

The construction of the displacement converter, which is known per se, consists in the embodiment described here of two toothed belts which are guided laterally with the piston rod. These toothed belts are each fixedly connected to the housing on the one hand and to the driving body on the other hand.

The toothed belts roll over two pairs of roller sets (7) which are rigidly connected to each other by a roller retaining device. In this case, the roller holding device is also connected to the piston rod of the cylinder.

When placing such a variable displacement transmission on a moving piston rod, it is necessary, for example, that shearing forces (lateral loads) or various moments that can induce jamming of the piston rod occupy the piston rod, especially in the column position. In order to prevent this from acting on the piston rod, space requirements are imposed and, moreover, expensive constructional measures have to be taken.

In the known example mentioned here, this condition is satisfied by investing a certain amount of expense, but in order to do so, two roller holding devices arranged symmetrically with respect to the piston rod axis are required. Since it is necessary to use the force that acts in the longitudinal direction of the piston rod axis,
It arises from individual power.

An object of the present invention is to construct a linear drive device that is operated by pneumatic force, hydraulic force, or electricity in an extremely simple and compact manner (8). A particularly advantageous embodiment provides for the linear drive to be resistant to high shear forces and to dirt.

To solve this problem, the invention provides that the part important for the stroke transformation, which is located between the driven driver and a predetermined reference point in the transmission, is a longitudinally guided movable reciprocating It is fixed to the dynamic cylinder, and the fixation in this case is such that the cylinder itself is located in the supporting and driving part of the transmission.

Note that in this case, the piston rod of the cylinder is held stationary.

The force exiting the variable stroke transmission and acting as a moment at the cylinder is caused by the longitudinal guide of the cylinder,
Alternatively, it may be absorbed by the bearing or at the end of the cylinder.

Another feature of the invention is a slitted hollow molded body, in which a driving body is held for external linear movement, and furthermore, this driving body is It is connected to the internal displacement transmission through the slit.

If the surface is to be rendered insensitive to soiling, the slits can be provided with known protective strips or the like.

Another feature of the invention is that the interior of the hollow profile, which generally defines and supports the linear drive, can be configured as a longitudinal guide for the cylinder reservoir. If such measures are taken, an extremely compact linear drive device can be realized.

Furthermore, according to the invention it is possible to co-operate the reciprocating cylinder, or even the rotary part of the transmission, for example in a linear drive, with known devices for positioning or speed control.

The invention will now be described in detail with reference to some particularly advantageous embodiments, which are illustrated in the accompanying drawings.

First, FIGS. 1 and 2 will be described.

The driving body (1) can be constructed as a sliding bearing capable of linear movement or as a rolling bearing, and a suitable coupling device (not shown) for the drive member or components can be connected to the driving body (1). It can be used for. The driver (1) is guided along a slit hollow profile (3).

As is clear from FIG. 3, which is a cross-sectional view taken along the line ■-■ in FIG. 2, in this embodiment, the hollow molded body (3) is formed as a single rectangular pipe. .

This hollow molded body (3) is a supporting element in the linear drive and largely determines its external dimensions. lateral forces transmitted to this system via the entrainer (1);
The shear force of the toe is absorbed by the hollow molded body (3).

At both ends of the hollow molded body (3), fixing plates are provided to enable rational assembly of the linear drive device.
41 can be attached. The joint plate (2) of the driver body (1) passes through a slit drilled in the hollow profile (3) into the profile and is fixedly connected there to the displacement transmission.

This variable displacement transmission of known type consists essentially of two rollers (5). These rollers (5
) are fixed to the roller carrier at a distance of at least the distance to be transformed.

In this case, the function of the roller carrier is entrusted to the cylinder (6), the cylinder cover of which laterally holds the roller (5) via a rigid shaft.

This lateral fixing style does not necessarily have to be adopted in the case of the present invention, and the cylinder cover (7)
In addition, the roller (5) can also be fixed on the end face side. Further, a rope (8), which is a component of this stroke variable transmission, is wound around a roller (5), one end of which is fixedly connected to a joint plate (2), and the other end of which is connected to a hollow It is coupled to a fixing member provided on the molded body (3).

It is needless to say that a chain, a steel strip, a toothed belt, or the like may be used instead of a rope, and a slide guide for a roller chain may be used instead of a roller.

The longitudinal guide of the movable cylinder (6) is provided by the inner surface of the hollow profile (3). It is advantageous if the cylinder cover (7) is configured as a slide bearing, for example on three sides.

The piston rod OI of the cylinder (6) is held at its end in a holding device (11), which itself has a fixing plate (
4) is fixed.

In the linear drive shown in FIG. 1, the piston rod (II) occupies an external position, a piston, a position protruding from the cylinder. Once fed into the cylinder (6), the reciprocating cylinder (6) moves to the position shown in FIG. 2, and the piston rod 0I occupies the self-propelled position.

As one of ordinary skill in the art will readily appreciate, the stroke of the reciprocating cylinder (6) is transmitted to the driver (1) in the above process in a ratio of 1:2. This movement process is, surprisingly, reversible.

In FIGS. 4 and 5, parts that are equivalent to those in FIGS. 1 and 2 are given the same reference numerals.

The main point in which the embodiment of the linear drive according to FIGS. 4 and 5 differs from the embodiment according to FIGS. 1 and 2 is that the piston rod QOI is provided through-through. Both ends of this piston rod 0 are attached to the holding device Q.
1), it is rigidly connected to the fixed plate (4). This piston rod OI thus assumes the function of longitudinally guiding the cylinder.

It is clear that in this embodiment the cylinder cover (7) does not have to assume the function of a plain bearing. Therefore, in such a configuration mode, the hollow molded body (3
) are not subject to any requirements for the inner surface characteristics (surface quality).

Furthermore, in this embodiment, it may be assumed that the hollow molded body (3) is loaded with a much higher shear force than is allowed in the case of the first embodiment. In that case, this load causes the reciprocating cylinder (6) to
movement is often hindered.

The main features of the linear drive device described above include the following points.

Extremely compact and closed structure.

Minor components. Simple structure. High absorption performance of external shear force reservoir. Impeccable resistance to staining.

Many embodiments of the linear drive device are conceivable without departing from the spirit of the invention. It should be noted here that only mention is made of the possibility that the reciprocating cylinder or, for example, the rotary part of a variable-stroke transmission can cooperate with known positioning and speed control devices.

If such measures are taken, many fields of use will be developed for linear drives, in particular applications as operating machines.

6 to 9, an embodiment of the linear drive according to the invention is shown in more detail.

What is shown in each figure in this case is the second
This corresponds to a cross-sectional view of the linear drive device taken along the line ■-■ in the figure or the line ■-■ in FIG. In the illustrated embodiment, it is possible to selectively use a piston rod that is anchored on one side or a piston rod that is anchored on both sides.

The linear drive device according to the invention, shown in FIG. It is shown in

The reciprocating cylinder (2+1 cylinder (6) surrounds the piston (2 hot water), and the piston (2) slides closely inside the cylinder (6) while being held by the piston rod 0I. Moreover, as is evident from the illustrated one of the two cylinder covers (7), said cylinder cover closes the reciprocating cylinder (2++) on both sides and cooperates with the piston rod to open the interior of the cylinder twice. It is divided into two work rooms.

These working chambers are optionally loaded with a hydraulic or pneumatic working medium, thereby producing a driving movement between the piston (2) and the cylinder (6).

Instead of hydraulic or pneumatic reciprocating cylinders, it is also possible to use electrical reciprocating cylinders, which have a spindle device driven by an electric motor, so-called electro cylinders. ” is known as.

In each case, the generated driving force is transmitted via a variable-stroke transmission to a linearly movable driver (1).

In this case, according to the core idea of the invention, the piston rod a with the piston (23) is fixedly arranged in the casing (a), whereas the cylinder with the variable stroke transmission (6) is movable while being guided in the longitudinal direction.

The casing (2) shown in FIG. 6 is constructed as a hollow molded body with slits. This appropriately formed slit ff13 along the direction of movement of the driving body (1),
It extends over the entire linearly extending range of its adjustment stroke.

A joint plate (2) passing through this slit (c) is connected to a stroke shift transmission.

The driving of the driver (11), which is guided along the casing (2) for linear movement, takes place by means of this variable-stroke transmission and the joint plate (2).
It may be carried out along the outer surface (c) of the casing (a) as shown in FIGS. It may be done.

Regarding Fig. 6, the hollow molded casing ■
has a rectangular cross-sectional shape. The entrainer (1) is
It is formed as a cylindrical metal object that fits this contour shape, a so-called stirrup. The stirrup has a casing (
(b) with its entire surface, leaving some play, and then engaging the casing (
b). In order to guide the driving body (1) as friction-free as possible, a plurality of wheels +27+ are provided, but it is also possible to use rollers, drums or other rolling elements instead of the wheels, for example. It is.

These wheels (5) are arranged in the stirrup-like driving body (1) in the area of two mutually diagonally located corners (c) and are located on the outer surface (h) of the casing (a). ) is supported offset by 90°.

On the other hand, the wheel is not provided at the third corner of the stirrup, and at the fourth and final corner, the stirrup is provided with a wheel in the range of the longitudinal edge (A) of the casing ■. The wrap is open.

Over the entire depth of the driver (1) perpendicular to the drawing plane of FIG.
) are provided in succession one after another, so that the driving body (1) is ensured safely even against angular deviations (tilting).

Because this arrangement is adopted, the casing (
It is clear that a particularly stable and friction-free guiding of the driver (1) along the outer surface Qω of 21 is ensured.

Furthermore, FIG. 6 shows one of the rollers (5) of the variable stroke transmission. These rollers (
5) are each fixed to the cylinder (6) of the reciprocating cylinder 0D at a predetermined interval.

In this case, each roller (5) is seated on an axis that is oriented transversely (at right angles) to the longitudinal direction of the cylinder and to the direction of movement of the pawl driver (1). . These shafts (7) are themselves held by the cylinder cover (7) K, which closes off both sides of the cylinder (6). A rope (8) is especially wound around each roller (5) as a traction member.
8) is connected to the casing (a) and the driving body (1).

In this case, the fixing member (9) is used to attach the roller (5) to the casing (A), and the fixing member (9) is used to attach the roller (5) to the casing (A).
The connection between the drive body (1) and the driving body (1) takes place via a seam plate (2).

According to FIG. 6, each roller (5) has a traction member (8).
) is arranged next to the reciprocating cylinder (21) in a section close to the edge of the casing (2). In contrast, the sill t23+ for the seam plate (2) advantageously extends approximately centrally on the surface of the housing (2).

This joint plate (2) is therefore bent over for fixation to the traction member (8) and is also stepped at its fixed end.

The variable stroke transmission has only one pair of roller sets (5), arranged laterally of the reciprocating cylinder (2+1) and with associated ropes (8). The seam plate (2) bent at is connected.

Although this off-center, asymmetrical arrangement of the variable stroke transmission does create shear forces during operation, in almost all applications these shear forces are (A) It can be easily absorbed by the hollow molded body.

However, in order to cope with particularly large tensile forces, such as those that can occur, for example, in hydraulic drives, two-stroke variable transmissions are required.
It is advantageous to have a large number of them.

In the embodiment shown in FIG. 7, a pair of roller sets (5) are arranged on each side of the reciprocating cylinder 011, and a separate pulling rope (8) is wound around each roller set. ing. Each roller set (5) is provided in a symmetrical arrangement on mutually opposite sides of the reciprocating cylinder Q).

Both traction ropes (8) are themselves fixedly connected to the casing (a) at the anchoring element (9), and the driver (1) is engaged with these traction ropes (8). There is.

For this purpose, a single-shaped seam plate (2) is used, the projecting surfaces of which extend on both sides beyond the reciprocating cylinder (21) above the variable-stroke transmission and are of suitable design. It is connected to a traction rope (8).

The leg of this T-shaped joint plate (2), the tab base 01) penetrates the slit (231) drilled in the burnt casing (A) and protrudes into the casing, and the outer surface of the casing (■) It is integrally molded with the driving body (1) which is guided along (c).

In this embodiment as well, guidance is provided by a plurality of cars Qη, but the arrangement of the cars is different from that in the previous embodiment.

The driver according to FIG. 7 also has a stirrup shape, but in this case the longitudinal side facing the seam plate (2) is open. The stirrup opening 0 is located approximately at the center of the casing. A pair of military discipline 0■ is provided on both sides of the stirrup opening 02. In this case, the respective axes of the affiliated military discipline 03 are aligned with each other.

A similar pair of military disciplines (34) are also placed on both sides of the joint plate (2) on the opposite side. On the other hand, on the lateral surface of the entrainer (1),
Each is provided with a single car (27).

Regarding each wheel (5) shown, it goes without saying that a series of wheels (5) is provided over the entire depth of the driver (1) perpendicular to the drawing plane. These cars Qη are
Each of them is supported on Q external surfaces of the casing (1), the respective bearing points being located symmetrically opposite each other.

If this type is adopted, the entrainment body (1
1 guidance is guaranteed.

Furthermore, by providing the variable stroke transmissions in this manner in duplicate on both sides of the reciprocating cylinder (2]), shear forces of this type are at least partially compensated for each other, and the loads on all components are , can be kept small.

Naturally, this also applies to both towing ropes (8) to a large extent, and the tensile force generated during the operation of the reciprocating cylinder (21) is distributed approximately half to each of these towing ropes (8). will be done.

In the embodiment according to FIG. 7, the respective shafts (7) supporting each roller (5) rest against the cylinder cover (7) in mutually aligned alignment on both sides.

As in the case of Fig. 6, a distance is maintained between the cylinder cover (7) and the inner wall +24) of the casing (A), and the linear drive device on the outside of the reciprocating cylinder (20) The components are also spaced apart.

This means that cylinder (6) of reciprocating cylinder (21)
The same applies to itself. The tab and cylinder (6) are attached to the inner wall (2) of the casing (A) together with the cylinder cover.
It can be slid at a distance from 4.

This sliding movement takes place along the piston rod QOI when the reciprocating cylinder (211) is loaded.

In that case, the cylinder (6) is guided exclusively along the piston 03. As already mentioned, in this arrangement, it is desirable to stably support the piston rod 0 at both ends of the casing (2).

FIG. 8 shows a further embodiment of the linear drive according to the invention. In this case, the entrainer (1) is guided inside the casing (2). From this driver (11), only the joint plate (2) projects to the outside through the slit (2) in the casing (21), whereas all other parts of this linear drive It is integrated and integrated inside the casing (A).

This extremely compact and closed construction ensures perfect protection against dirt or the influence of aggressive media.

The casing (A) in this embodiment is also configured to have a rectangular shape, and only one pair of rollers (A) is provided on the side of the reciprocating cylinder (6).
5) is used. However, in this case, you have to be careful because the entrainer (
This arrangement of internal guides for 1) is by no means mandatory.

For example, it is also possible to use, especially for this purpose, a variable stroke transmission, which is arranged on both sides of a cylindrical casing (the edge or the reciprocating cylinder 01), the number of which is twice the number of rollers. (not shown).

Depending on the rectangular contour shape of the casing (A), the entraining body (
1) has an L-shaped shape. On each end face of this L-shaped semi-molded body and on the outer surface (7) of the L-shaped leg 0η, the inner surface C! of the casing ■! 4) A vehicle e supported by the vehicle e is placed respectively.

In this case, the entraining body (1) is attached to the casing ■ with play.
and the vehicle (5) of the entraining body (1).
) is the entire inner surface of the rectangular hollow molded body c! 4).

In the exemplary embodiment, too, there are not only the wheels (5) shown, but a series of wheels distributed over the entire depth of the driver (1) and aligned with one another in a direction perpendicular to the drawing plane. It goes without saying that these wheels (5) serve as a means of protection against angular deviation within the casing (2).

One of the L-shaped legs OD extends beyond the variable stroke transmission and is connected to the associated traction member (8), which is also fastened at the same time to the casing (a) by means of a fastening member (9). combined.

The reciprocating cylinder ffl+1 is housed together with the variable stroke transmission in the L-shaped opening of the driver (1). In this case, the cylinder (6) of the reciprocating cylinder (21) moves with play at a distance from the casing (a) as well as from the driver (1).

Therefore, this cylinder (6) is also supported only on the fixedly arranged piston (a).

The linear thrust force of the driver 0) produced by this movement in the cylinder (6) can be transmitted to the different parts to be manipulated.

Therefore, the joint plate (2) protruding from the casing (A)
, one or more mounting holes are drilled into the holes, and an appropriate corresponding piece of the member to be operated is installed in the holes. In particular, it can be fixed with screws.

Finally, FIG. 9 shows an alternative embodiment for supporting the driver (1). This driver fil is guided along the casing (2) and the cylinder (6) of the reciprocating cylinder (21). The reciprocating cylinder (21) has a circular cross section, and the driving body (11) has a ball bearing bushing c3I with a slit that rolls on the cylinder (6) of the reciprocating cylinder (21). In addition, this entrainment (
1) is a segmented ring stirrup (41
is engaged around the ball bearing bushing (31).

In this case, the slit range (41) of the ball bearing bushing OI and the notch (421) of the ring-shaped stirrup f4I are located so as to overlap with each other. This is required in order to be able to fix the roller (5) to the cylinder (6).

The shaft (7) of the roller (5) is in contact with the cylinder (6) of the reciprocating cylinder (21) in the slit area (41) of the ball bearing bushing C31.

A traction rope (8) is wound around the roller (5), and this traction rope (8) is connected to the L-shaped member (
It is fixedly fixed to the casing (A) through the mouth.

The other end of the traction rope (8) is connected to the driver (1) via a holder (44), which is brought into contact with a ring-shaped stirrup (41) and is It engages the transmission from above.

Furthermore, this ring-shaped stirrup (41) is integrally molded with a joint plate (2) that protrudes outside the casing (A) through the slit Q. In order to ensure that there is no relative rotation on the bushing OI, at least one wheel (5) running on a suitably formed rail is provided with a joint plate (two rivers). In a simple arrangement, the car (5) is supported by the four side edges of Q3, and the joint plate (two
) protrudes through this slit.

In the linear drive according to FIGS. 6 to 9, the cylinder (6) is guided entirely by the piston @ on the piston rod a1, but for example, one or more inner walls 041 in the casing 6), it is also possible to use a very similar construction style. Especially in that case,
The cylinder cover that closes the cylinder (6) on both sides (
7) can be configured as a sliding υ bearing that moves along the guide surface.

Furthermore, configuring the casing (2) as a rectangular hollow body is not an essential requirement, at least for some of the configurations described above; for example, it is not necessary to configure the casing (2) as a rectangular hollow body. Accordingly, it is also possible to slide the ring-shaped driver along the inner or outer wall of the hollow profile. Such an arrangement is shown schematically in FIG.

According to the invention, it is possible to provide precisely operated and well-protected linear drives in different configurations. In this case, the guide surface with many material requirements is
It is only necessary to provide this for only half the stroke of the linear drive.

With the piston (2) fixed, move the movable cylinder (6
), the linear drive according to the invention can be constructed extremely compactly.

The roller (5) of the variable stroke transmission is connected to the reciprocating cylinder (
It is possible to install the cylinders (6)K at intervals corresponding to the piston stroke of 21).

The resulting linear drive configuration length in any case only slightly exceeds twice the piston stroke length. That is, its structural length is approximately equal to the stroke of the driver.

In the embodiment with the piston rod 0 fixed at both ends of the casing (a), the cylinder (6) supporting the variable displacement transmission is guided optimally and satisfactorily in every position.

Even if an eccentric force is introduced into the cylinder (6) via the variable displacement transmission arranged on one side, this force can be easily absorbed by the piston rod Q[e.

Furthermore, if the piston rod is arranged in a consistent manner and supported on both sides, a special advantage is obtained that the forces in both the forward and reverse directions are equal.
