Description

Detailed Description of the Invention (Field of Industrial Application) The present invention has a cylinder tube whose both end faces are closed by cylinder covers, and a piston that is slidable in the axial direction is provided in the tube. There is,
The piston is fixedly connected to a piston rod which is inserted in a sealed manner through at least one cylinder cover, and further includes at least one longitudinal member parallel to the longitudinal direction of the cylinder tube on the outer surface of the cylinder tube. and a mounting member of at least one proximity switch or the like arranged therein.

(Prior Art) In the above-mentioned type of piston/cylinder mechanism, at least one vertical member is a tie rod, and one cylinder cover is removably fixed to each end face of the tie rod. It can be fixed to the cylinder chute.

Usually, four tie rods are arranged at equal intervals on the outer peripheral surface of the cylinder tube.

(Problem to be Solved by the Invention) This type of piston-cylinder mechanism is particularly useful when high pressures occur in the cylinder tube and therefore the cylinder cover must be specially protected from being blown off. used.

When this type of device is installed in a machine, depending on the relative position of the piston to the cylinder tube,
A desire often arises to trigger a specific machine function. For this purpose, a proximity switch or the like is mounted on the outer surface of the cylinder tube, and when the piston passes radially inside the mounting location, the switch emits a signal that can be processed further.

This proximity switch or the like is generally mounted directly to the cylinder tube, for example by screwing, by means of a fitting such as a mount. The necessary screw holes for this must already be made before the cylinder actuator is inserted into the cylinder tube, so it is almost impossible to accurately adjust the response time of the proximity switch afterwards, and the cylinder tube Only a less precise position adjustment is possible at certain points.

The known arrangement is therefore unsuitable for precise control purposes. Moreover, the proximity switches and fittings are extremely time consuming to install and remove. Also,
It is virtually impossible to additionally equip a commercially available operating cylinder with a proximity switch or the like under the conditions mentioned.

The present invention provides a piston-cylinder mechanism of the type mentioned above, which allows the proximity switch to be easily installed and removed, allows the response time of the proximity switch to be accurately adjusted, and is simple and inexpensive to manufacture and construct. The purpose is to provide.

(Means for solving the problem) The purpose is to provide a longitudinal guide for a fitting part of a proximity switch or similar, which has a guiding surface and a clamping surface, both surfaces of which extend in the circumferential direction of the cylinder tube. The mounting parts are arranged on mutually opposing longitudinal sides of the longitudinal guide facing away from each other, and the mounting parts are slidable in the longitudinal direction of the cylinder, the mounting sides are attachable to the longitudinal guide, and The longitudinal guide completely or almost completely penetrates into a mounting groove cut into the mounting part from the mounting side and extending over its entire length, the mounting groove being such that the first side wall following the interface is vertically The second side wall is in contact with the guide surface of the guide, and includes at least one fastening component spaced apart from and facing the vertical mounting surface and acting on the clamping surface, for removably securing the mounting component to the vertical guide. This is achieved by providing a fastening device in the mounting groove.

That is, the mounting part supporting the proximity switch or the like can be mounted on the longitudinal guide in virtually one operation and can be slid in the longitudinal guide and adjusted steplessly in the desired position. Once the desired working position has been reached, the fitting can be secured against movement by means of a tightening device.

The longitudinal guide can be formed directly by tie rods. This provides the possibility of additionally equipping a conventional cylinder with a proximity switch, especially without additional machining. Since the fitting surrounds the longitudinal guide on both sides, the fitting is held securely on the longitudinal guide and cannot slip off.

Since the mutual spacing between both side walls of the mounting groove is larger than the width of the vertical guide, there is no need to require very strict conditions for the dimensional accuracy of the vertical guide, and the mounting parts can be firmly mounted even to tie rods or similar items with different diameters. be able to.

Advantageous developments of the piston-cylinder arrangement according to the invention are specified in the claims 2 to 25.

The stringers or longitudinal guides can preferably be constructed as profiled rails integrally molded onto the cylinder tube. In this case, preferably, this irregularly shaped rail has the following features as specified in claim 3:
It additionally serves the role of a tie rod.

With the structure of claim 5, the guide surface and the clamping surface of the vertical guide can extend in the direction of the cylinder tube in the shape of a wedge. In this case, the clamping part acts on the clamping surface when the mounting part is mounted in the area of the outer circumferential surface of the cylinder tube. When this clamping element acts on the clamping surface, it generates a tensile force that supplements the clamping force and biases the fitting towards the cylinder tube, providing additional centering and improved retention of the fitting. .

With the arrangement according to claim 6, a more precise fixing of the fitting part, and therefore of the proximity switch or the like, can be achieved. I mean,
This is because the distance between the proximity switch and the piston that triggers it or the magnetic component attached to it must always be maintained precisely to ensure accurate response of the proximity switch.

With the configuration of claim 6, the mounting part is prevented from pivoting around the longitudinal axis of the vertical guide,
The distance between the proximity switch and the cylinder tube is always kept constant even when the attached parts are sliding or after sliding.

According to the structure of claim 10, it is possible to manufacture the device extremely simply and at low cost.

With the configurations of claims 11 to 18, the clamping force can be transmitted over a wide area from the clamping device to the clamping surface of the vertical guide, and the flat press ensures reliable retention. is obtained. Furthermore, damage to the longitudinal guides is eliminated by this departure from point clamping. In the case of spot tightening, impressions of the tightening points remain on the longitudinal guide, making subsequent fine adjustments of the fittings extremely difficult.

In this connection, the advantageous embodiment of patent claim 16 can be produced very simply, approximately in one step, for example by injection molding.

In the configuration of item 17, if the pressure member breaks,
The exchange can be done without difficulty.

With the structure of claim 19, attachment to and detachment from the cylinder tube can be performed quickly and without difficulty.

In the structure of claim 20, the point-like tightening force supplied from at least one tightening screw and acting on the pressure member is transmitted in an evenly distributed manner to the tightening surface of the vertical guide, thereby ensuring reliable can be tightened to protect the tightening surface from damage.

(Example) Hereinafter, the present invention will be described in detail based on illustrated examples.

First, FIG. 1 and FIG. 2 will be explained.

As can be seen from the figure, the piston-cylinder mechanism has a cylindrical cylinder tube 1, the end surfaces of which are hermetically closed by cylinder covers 2 and 3, respectively.

A piston (not shown) is disposed inside the cylinder tube to partition the cylinder interior into two pressure chambers. The piston is slidable in the longitudinal direction 4 of the cylinder tube 1.

A piston rod 5 is coaxially attached to the piston, and the rod is attached to one cylinder cover 3.
is inserted under a coaxial hermetically sealed condition. The power take-off part can be attached to the part located outside the cylinder tube.

2 shown with a wavy line that passes through each cylinder cover
Two channels 6, 6' are provided, through which the pressure chamber can be selectively supplied or discharged with pressure medium in order to cause the movement of the piston and piston rod.

On the outer surface of the cylinder tube 1, there are four vertical members 8
are arranged parallel to the longitudinal axis 4 and evenly distributed on the circumferential surface of the cylinder tube 1. The vertical members are irregularly shaped rails 14, 15, 16, and 17, respectively.
The outer or outer surface 7 of the cylinder tube 1 in the form of
The tube is integrally molded with the tube to form an irregularly shaped tube 9. In the cross-sectional view shown in FIG. 1, the profiled rails 14 to 17 have an eye shape that projects radially from the cylinder tube.

The irregularly shaped rails 14 to 17 each have a length equal to the length of the cylinder tube 1, and blind screw holes 20 are bored in the axial end portions 18 and 19 from the end surface side in the axial direction. Coaxially with the screw hole 20, the cylinder covers 2, 3 each have a through hole 21 in the corner area, through which a mounting screw 22 is inserted and screwed into the screw hole 20. In other words, the irregularly shaped rails 14 to 17 serve as tie rods to securely fix the cylinder covers 2 and 3 to the cylinder tube 1.

A proximity switch 24 is attached to the outer surface of the irregularly shaped tube 9 by a mounting part 23. The switch includes a reed switch 25, which is removably attached to the mounting part 23 and is indicated by a dashed line.

When a piston made of magnetic material and passed inside the cylinder tube or containing a magnetic insert passes the reed switch, the reed switch generates a control signal via the signal line 27.

The attachment part 23 is detachably attached to one of the irregularly shaped rails 16 forming the longitudinal guide 10, and the attachment part 23 slides along the longitudinal guide. The vertical guide 10 has a guide surface 29 and a clamping surface 30, and both surfaces 29 and 30 face oppositely to each other and are arranged on opposite longitudinal sides of the vertical guide when viewed in the circumferential direction of the cylinder tube 1. be. Both sides are preferably flat and, viewed in the radial direction, the cylinder tube 1
is in direct contact with the outer circumferential surface 7 of.

In this embodiment, four irregularly shaped rails 14 to 1
7 all have the same configuration, cylinder tube 1
A plurality of proximity switches can be distributed and arranged around the circumferential surface. In this case, the proximity switch does not become an obstacle when sliding in the longitudinal direction.

The guide surface 29 and the clamping surface 30 of each irregularly shaped rail 14 to 17 can be arranged parallel to each other with a distance between them. Note that this distance is approximately equal to the thickness or diameter of each irregularly shaped rail. With the cylinder tube longitudinal axis 4 as a reference, they can be provided equidistantly on both sides from planes oriented in the axial and radial directions.
This embodiment is omitted from illustration.

On the other hand, it is much better to arrange both surfaces 29 and 30 on opposite sides of the reference plane 31 oriented in the axial direction and the radial direction with the longitudinal axis of the cylinder tube as a reference, when viewed in the circumferential direction of the cylinder tube 1. It is advantageous for In this case, the planes 32, 33 containing these surfaces 29, 30 start from each rail of different diameter and converge in the direction of the cylinder tube. The planes 32, 33 thus form acute angles α, β, respectively, with respect to the reference plane 31, and the two angles α, β are preferably identical.

The longitudinal axes of the irregularly shaped rails are each on the reference plane 31. This conical progression oriented towards the outer circumference 7 provides optimum results in terms of the security of the fastening of the fittings. This point will be discussed in detail in another section.

The only fitting 23 shown in FIG. 1 is mounted on the longitudinal guide 10 so as to be slidable in the 4 directions of the longitudinal axis of the cylinder tube. The longitudinal guide 10 then virtually completely enters the mounting groove 34 drilled in the mounting part 23 from the mounting side 35 of the mounting part 23 facing the cylinder tube 1 .

The mounting groove 34 is approximately rectangular in cross section with a U-shaped profile and has a flat groove/side wall 35 that continues to the interface 35.
has a shape complementary to the guide surface 29 and comes into contact with the guide surface. The width of the mounting groove 34 measured between the first groove/side wall 35 and the opposing second groove/side wall 36 is larger than the distance between both surfaces of the vertical guide 10, and the second groove/side wall 36 is tightened. It faces the attached surface 30 at a distance.

A tightening device 37 is provided in the second groove/side wall 36 . The tightening device acts on this tightening surface 30 in order to securely and removably fix the fitting 23 to the longitudinal guide 10 . Alternatively, it may be fixed or fixable thereto.

The mounting part 23 has a shape similar to that of a rocker, and has a V
It has two mounting legs 38, 38' which are arranged in the form of an obtuse angle with respect to each other (see FIGS. 3 and 4).

From the opening side 39, which is the same as the mounting side surface 28, the mounting groove 34 connects to the V-shaped mounting part 23, and both legs 38,
They are carved almost symmetrically with reference to 38'. The mounting groove 34 preferably has a substantially rectangular or square cross-section, the contour of which, i.e. the arrangement of the groove walls, being U
It is the shape.

The mutually opposing grooves/side walls 35, 36 are preferably arranged parallel to each other and each lie on a parallel or substantially parallel plane with respect to the longitudinal neutral plane 40 of the mounting part 23.

The longitudinal midplane 40 is formed by the mounting groove 34 or the vertical guide 1
0 in the longitudinal direction, and two mounting legs 38, 3
8' forms a so-called assumed separation surface. Due to the carved mounting groove, the shape of the mounting part 23 is as follows.
When viewed in cross section, it gradually becomes U-shaped.

The depth of the mounting groove 34 is approximately equal to the height of the longitudinal guide 10 measured in the radial direction of the cylinder tube 1, or advantageously slightly larger.

When the mounting parts 23 are installed, each longitudinal guide 10 can completely enter the mounting groove 34. In this case, the parts 44, 44' of the two mounting legs 38, 38' facing the mounting side 28 bear simultaneously against the outer surface 7 on both sides of the longitudinal guide 10.

This prevents the mounting part 23 from pivoting about the longitudinal guide 10 even slightly, even if the mounting part slides along the longitudinal guide and changes its position (in the direction of arrow 46). At the same time, the distance 45 between the proximity switch 24 and the outer surface of the cylinder tube 1 can always be maintained at a constant value, which is essential for the functional accuracy of the proximity switch.

As this distance 45 increases or decreases, the response of the proximity switch to an approaching piston or magnet arrangement attached thereto will be delayed or premature.
This type of drawback is eliminated with the present invention.

Of course, the mounting groove is the first groove/side wall 35 and the groove bottom 47.
Rounding can be done in the range between (48 points). This chamfer is preferably designed to complement the outer contour of the longitudinal guide 10. This allows the guide surface 29 and the side wall 35 to come into close contact, making the vertical guide more reliable.

Next, the tightening device 37 will be explained in detail.

In all of the illustrated embodiments, the tightening device is
The mounting leg 38' facing the tightening surface 30 is inserted into the second groove.
It comprises a threaded hole 49 passing through at right angles to the side wall 36, in which a clamping screw 50, preferably configured as a set screw, reciprocates and extends in the direction of the clamping surface 30 of the longitudinal guide 10 and vice versa. It can be screwed in the direction. The longitudinal axis of the clamping screw is perpendicular or nearly perpendicular to the clamping surface 30.

Furthermore, another screw hole 49 and a tightening screw 50' are provided, and the two tightening screws are spaced apart from each other in the front and back when viewed in the longitudinal direction 4 of the cylinder tube 1, as shown in FIG. There is.

The tightening device 37 connects the mounting parts 23 and the vertical guide 10.
and at least one clamping part supported between the clamping parts, which can be fixed directly to the clamping surface 30.

In the embodiment of FIG. 4, which is characterized by a particularly simple structure, the clamping part 51 is directly attached by means of two clamping screws 50, 50', and the second
It spans the space between the groove/side wall 36 and the tightening surface 30. Its end face 52 acts directly on the clamping surface 30 .

When the tightening screw is biased in the direction of the tightening surface 30, the guide surface 29 and the first groove/side wall 35 opposing it come into contact, and the mounting part 23 is firmly clamped. However, in order to make the mounting part 23 movable in the longitudinal direction (arrow 46) of the vertical guide 10, both tightening screws 5
Just loosen 0.50' slightly.

In the embodiment shown in FIGS. 1 and 3, each of the fastening parts 53 includes a plate-shaped pressure member 54 disposed between the fastening surface 30 and the second groove/side wall 36 facing thereto. It is. It is attached to the mounting part 23 in the region of the groove bottom 47 of the mounting groove 34 and projects into the mounting groove 34 in the form of a tongue.

The pressurizing component 54 has a substantially rectangular plate profile, and its plate surface is parallel or substantially parallel to the first side wall 35 of the mounting groove 34 . The length of the pressure member 54 measured in the longitudinal direction 4 of the cylinder tube is the length of the mounting groove 34.
equal to the length of The pressure element 54 is preferably attached to the mounting part 23 in a flexible manner and in the area of its longitudinal edge 56. In this case, there is no need for a hinge or the like, and the pressure member 54 obtains its elasticity only from the material selected for it. The pressure member therefore consists of a bendable elastic material.

The pressure member 54 is quite thin compared to its width and length, and from this point alone, a certain degree of flexibility is ensured. Second groove/side wall 36 of pressure member 54
When the pressure member is stretched over almost the entire depth of the mounting groove 34 and the mounting part 23 is attached to the vertical guide 10, the width measured in the direction parallel to the longitudinal edge of the pressure member is is selected so that it abuts a portion of the clamping surface 30 adjacent to and at a very slight distance from the outer surface 7 of the cylinder tube 1 .

In the embodiment shown in FIG. 1, the pressure member 54 is constructed integrally with the mounting part 23, and both members are manufactured as follows.
It is possible in one step.

On the other hand, in the configuration shown in Figure 3,
The pressure member 54 is configured separately from the mounting part 23 and has an insertion groove 57 extending in the longitudinal direction of the mounting groove 34.
The insert part 58 is inserted into the insert part 58. The insertion groove is configured as a surface groove carved in the groove bottom 47 of the mounting groove 34, and the range of the groove bottom 47 (62 locations)
The width is narrow in this section, but the width is wide at a section 63 following this section 62.

The longitudinal edges of the pressure member 54 are configured to be complementary. The pressure member can be inserted, preferably press-fitted, into this insertion groove 57 from the side of the axial end faces 64, 64' facing the longitudinal direction 4 of the attachment part 23.

In the last-mentioned configuration, if the pressure member 54 is damaged,
For example, if it breaks, it has the advantage that the pressure member can be easily replaced without replacing the entire attachment part 23.

The distance between the first groove/side wall 35 of the mounting groove 34 and the opposing tightening side surface 66 of the pressure member 54 is equal to 1 yen of the cylinder tube between the tightening surface and the guide surface of the vertical guide 10. Almost equal to the distance measured in the circumferential direction. This allows the mounting part 53 to

come into contact with.

In this way, when the tightening screw 50 is screwed in the direction of the vertical guide 10, the end surface 52 of the tightening screw
4 to fix the pressing member to the clamping surface 30.

In other words, the tightening screws 50, 50'
4 can be converted into a clamping force distributed in a plane between the clamping side surface 66 and the clamping surface 30. Tightening part 5 against tightening surface 30
3 is pressed flat in this way, the tightening surface is protected, and even when the tightening force is strong, the tightening surface 30
There will be no impression left on the surface. Furthermore, the distribution of the clamping force provides a much more stable holding than with spot pressure.

When the clamping screws 50, 50' are loosened again, the tongue-shaped clamping part 53 returns to its starting position and the fitting part 23
can be easily removed from the longitudinal guide 10 or slid in its longitudinal direction (arrow 46) and fixed again at any point.

When the tightening screws 50, 50' act on the pressure member 54, the pressure member 54 is moved to the fixed position of the groove bottom 47 (the third
(Figure 1) or can be bent back and forth within the range of the deformed area (Figure 1). However, since the distance between the guide surface 29 and the pressure member 54 is preferably precisely adjusted to the width of the longitudinal guide 10, the amplitude of the bending is negligible and the alternating bending load is negligible. However, the life of the pressure member 54 is not significantly affected.

In yet another non-illustrated embodiment of the present invention,
The clamping screws 50, 50' are omitted and the clamping force is supplied solely from the tongue-shaped clamping part 53. Preferably, the distance between the first groove/side wall 35 and the tightening side surface 66 of the pressure member 54 is such that when the mounting part is removed from the vertical guide 10, the distance between the guide surface 29 and the tightening surface 30 of the vertical guide is The mounting part 23 is smaller than the distance between
The pressurizing member 54 can be elastically bent and the gap between the pressurizing member and the first groove/side wall 35 widened so that it can be attached to the vertical guide 10. The tightening is done by the second side wall 36.
This is performed only by the elastic return force of the pressing member 54 bent in the direction. Preferably, the clamping surface 30 and the clamping side of the pressure member 54 are configured such that the fitting 23 can be snapped into the longitudinal guide 10.

As already mentioned, the tightening surface 30 and the guide surface 29 are slightly inclined by the angles α and β with respect to the reference surface 31, so that the attachment part 2 to the vertical guide 10 is
The certainty of fixation of item 3 is further increased. This is because due to the elastic flexibility of the pressure member 54, the first groove
This is because the side walls 35 and the clamping flanks 66 can rest tightly against the clamping surface 30 or the guide surface 29 even in this longitudinal guide embodiment. However, the first
Although the distance between the groove/side wall 35 and the tightening side surface 66 is smaller in the area of the outer peripheral surface 7 of the cylinder tube 1 than in the area of the groove bottom 46, the tightening force is supplemented.
A mechanical lock is created, whereby the longitudinal guide 10
This prevents the attachment part 23 from being removed from the housing.

The pressure member 54 is preferably provided with a longitudinal projection 68 in the region of its longitudinal edge and on the clamping side 66, which
In addition, the longitudinal guide 10 comes into contact with the clamping surface 30 in the area of reduced cross-section and in the vicinity of the outer circumferential surface 7 .

The optimum transmission of the clamping force exerted by the clamping screws 50, 50' is if the end face 52 of the clamping screw acts in the area opposite the longitudinal projection 68 of the pressure side 67.

Fixation of the nearby switch 24 to the mounting part 23 is as follows:
Preferably, it can be detachably attached using a mounting screw 69.
This mounting screw is laterally passed through the mounting leg 38 facing the tightening device 37, extends from the end face 70 of this leg facing in the circumferential direction of the cylinder tube 1, and is inserted into the screw hole of the neighboring switch 24 at this point. Screwed in to be detachable. The mounting screws 69 are then in the plane of the leg and are fully accessible.

In order to fix the position of the proximity switch 24, a position adjustment pin 71 is further provided. This pin has end face 7
It is inserted into the mounting part 23 from the 0 side, and the end face 7
0, and this protruding part is the proximity switch 2.
It can be inserted into hole 4. The proximal stitch can therefore be installed and removed at will, and its position can be reproduced at any time.

When the mounting parts 23 are attached to the vertical guide 10, they are arranged in a substantially roof-like shape with the cylinder tube 1 as a reference when viewed in cross section. Starting from the radially outer region of the longitudinal guide 10, the two mounting legs 38, 38' extend tangentially to the cylinder tube outer circumferential surface 7 at a distance therefrom. The two mounting legs 38, 38' are attached to the vertical guide 1.
0, and the proximity switch 24 is located almost opposite the top of the cylinder tube and between the two irregularly shaped rails 15 and 16.
