Description

Technical Field

[0001] The present disclosure relates to an annular elastic element of a pneumatic clamp and / or brake device and a housing member, and a pneumatic clamp and / or brake device having such an annular elastic element.

Background Art

[0002] In the manufacture of tools or machine members, processing machines, particularly work spindles or other machine tools, are used. These machines process materials from workpieces, particularly to a desired shape, using tools attached to a shaft. The shaft may be the rotating or pivoting axis of such a machine. Further, a rotatable or pivotable table is used with the shaft to position a tool or workpiece at an appropriate machining position or to move the workpiece at an appropriate rotational speed. A prerequisite for performing precise and efficient machining is, in particular, a high rotational speed of the shaft. Therefore, an emergency system or safety system has the problem of stopping or holding the shaft in a fixed position and fixing it when a system failure or malfunction such as a power outage or cable disconnection occurs.

[0003] At this time, general processing machines are equipped with electromagnetic, hydraulic or pneumatic clamp and / or brake devices. Such devices include a friction lining that can be frictionally connected to the shaft by force transmission. This makes it possible to fix the shaft at different speeds.

[0004] In the case of a hydraulic clamp device, hydraulic oil is supplied to the chamber and the rotating shaft or disk is clamped. Passive hydraulic clamps are also known. However, such hydraulic clamps have a long reaction time or a short reaction time requires very high costs. Further, hydraulic materials such as hydraulic valves and hydraulic pipes are expensive and require a relatively long time for assembly. Also, additional costs are required to maintain the cleanliness around the hydraulic clamp due to the hydraulic oil.

[0005] In the case of pneumatic clamps and / or brake devices, compressed air is generally supplied to the elastic elements, especially the elastic plates, which can overcome some of the drawbacks of the hydraulic clamp devices described above.

[0006] Patent documents 1 and 2 describe a pneumatic clamping device comprising two annular spring plates, which are introduced into the housing of the clamping device to form a pressure chamber, into which compressed air is supplied or the pressure chamber is ventilated, thereby changing the bending of the spring plates and switching between a closed state in which the clamping device is clamped, such as a rotatable shaft, and an open state in which the object to be clamped is free. However, in practice, it has become clear that such clamps cannot be operated without causing problems to the clamp and the environment in vacuum and cleanroom environments. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] European Patent No. 1585616 [Patent Document 2] European Patent No. 1651881 [Overview of the project] [Problems that the invention aims to solve]

[0008] Based on the prior art described at the beginning, the object of this disclosure is to provide a means for enabling pneumatic clamp and / or brake devices to operate reliably in a vacuum or cleanroom. [Means for solving the problem]

[0009] The problem is solved by an annular elastic element having the features described in claim 1, a housing member having the features described in claim 33, and a clamp and / or brake device having the features described in claim 46. Preferred embodiments are described in the dependent claims, specification and drawings.

[0010] The solution according to the present invention provides an annular elastic element for a clamping device and / or a braking device, the element comprising an annular spring plate having a first annular side surface and a second annular side surface, and a sealing element (hereinafter referred to herein as the "second sealing element" as it is located on the second side surface of the spring plate), the sealing element being located on the second side surface of the spring plate, the sealing element forming an inner projection in the region of the inner edge of the annular spring plate, and an outer projection in the region of the outer edge of the annular spring plate, the inner and / or outer projections of the sealing element each forming at least partially a bulge.

[0011] In this disclosure, the term “ring” should not necessarily be understood as a circular shape. Other ring shapes, such as angular ring shapes, are also included in this concept.

[0012] In accordance with the concept of "projection," the inner and outer projections protrude from or extend from one or more surfaces of the (second) sealing element. Preferably, the (second) sealing element is formed integrally with and / or integrally with the inner and / or outer projections.

[0013] According to the solution of the present invention, a housing member for a clamp and / or brake device is provided, the housing member comprising a ring for clamping an elastic element according to the present invention. It has a recess in the shape of the first annular edge and the second annular edge of the annular opening of the housing member. The annular edge is formed, and the annular recess is housing between the first annular edge and the second annular edge. The inner surface of the component is defined, and the inner surface forms a first inclination in the region of the first annular edge. , forming a second inclination in the region of the second annular edge, the inclination is such that the annular opening is first and It is positioned to expand toward the second edge. The bulge and inclination are part of the present invention. The elastic element and the housing member according to the present invention form a product that is related to each other. It is effective because each bulge can come into contact with one of the slopes.

[0014] According to the solution of the present invention, the object to be clamped and / or braked is further clamped A clamp and / or brake device for clamping and / or braking is provided, and the device is A first elastic element and a second elastic element according to the present invention, and a first having an inner surface, Preferably a housing member according to the present invention, and a second having an inner surface, preferably according to the present invention. A housing including the housing member, wherein the housing member is inside the housing member The surfaces are positioned relative to each other so as to divide the internal space inside the housing, and are tightly fitted together. A housing connected to one or more clamping elements, each clamping element is a clamp A clamping element having a surface, and a first elastic element and a second elastic element, arranged in an internal space. A spring in which the elastic element has a first pressure chamber in its internal space, and the elastic element and housing member It is arranged in the internal space so as to be formed between the inner surface and the first pressure chamber, It is possible to perform ventilation and apply positive pressure to a pressure medium that can be supplied to the housing, The elastic element 1 is positioned with its first side facing the inner surface of the first housing member, inside The second elastic element is clamped in space, and its first side is in the second housing. Clamped in the internal space in a state facing the inner surface of the material, the spring is such that when the first pressure chamber is ventilated or aerated, or when a positive pressure is applied to the first pressure chamber, at least one of the spring plates is configured to have variable bending, whereby the device has an open state in which the object to be clamped is separated from one or more clamping surfaces, and at least one clamping surface transmits a clamping force and / or a braking force to the object, and a spring that switches between the closed state and the inner or outer protrusion bulge of at least one elastic element is configured to establish contact with a first portion of the inner surface of one of the housing members within the housing member, whereby at least the fluid connection between the first pressure chamber and the transition portion with the housing member is blocked.

[0015] The problem that has long been unsolved with respect to the liable-to-fail operation of the clamping and / or braking device in a vacuum or clean room (the clamping fails and / or the surrounding atmosphere is contaminated by the clamping) has been overcome by aspects of the present invention. The following developments by the inventors each individually, and also in combination, contribute further to the overcoming.

[0016] For example, the inner and / or outer protrusions of the (second) sealing element can each form at least partially preferably a bulge (or a curve or an outwardly directed arch) extending radially, whereby for use in a vacuum or clean room, particularly good sealing performance is obtained at the transition portion of the housing member. The bulge can be formed by applying an additional (elastic) material of the sealing element to the remaining portion of the protrusion. The bulge, for example ​​​​​For example, in the gap region of the transition part of the housing member, the inner space within the housing member is sealed. , in contact with the inner wall of the housing member (e.g., a sloped or long chamfered portion) to seal it. It may be made so. Preferably, the bulge of the outer projection of the second sealing element is directed radially outward. Previously, preferably extending radially outward beyond the outer edge of the spring plate Preferably, the bulge of the inner projection of the second sealing element is radially inward. Preferably extending radially inward beyond the inner edge of the spring plate. Yes, they are.

[0017] For the sealing of the first pressure chamber against the gap at the transition of adjacent housing members, The bulge is particularly advantageous. The bulge, during the operation of the first pressure chamber, passes through the edge of the housing. This has the effect of resulting in little to no inflow or outflow of media.

[0018] Instead of the bulge, or in addition to the bulge, the inner projection and / or outer projection of the second sealing element. The protrusions preferably each have at least a partially flat surface, and such surface is, for example, , to function as a support surface for sealing, particularly against the housing wall or other elastic elements. This allows the clamp or its second pressure chamber to be separated from the second pressure chamber. To prevent or stop leakage into the surroundings, it is sealed more tightly. Flat surface The surface provides resistance to the permeation of the pressure medium (especially gas) when the pressure medium is supplied to the second pressure chamber. Increase. A flat surface allows for the overflow of the medium between the first and second pressure chambers. To reduce or prevent. Preferably, the bulges are close to or adjacent to the flat surface. Generally, flat surfaces merge into bulges.

[0019] The flat surface further assists in the displacement of the bulge relative to the inner wall of the housing member, and the bulge This also supports the aforementioned effects. This support, as mentioned above, is provided by the bulge with a flat surface. This is particularly noticeable when it is in close proximity to, adjacent to, and / or merges with a flat surface. The bulge to which it belongs therefore forms a combination of features that act synergistically, but individually It is also possible for it to exist in [location].

[0020] For use in vacuum or cleanroom environments, the elastic material used in the elastic element is preferred. In a vacuum, the material is hardly released, or not released at all (high media resistance), and at high temperatures. The material may be suitable and / or has low gas permeability.

[0021] In use in vacuum environments or cleanrooms, it further contributes to particularly good sealing performance. Therefore, the elastic element according to the present invention is for a first connection part for supplying a pressure medium to a first pressure chamber. It is possible to have a first connection seal, and the first connection seal tightly seals the first connection portion. To seal. Preferably, the edge of the first connection seal covers at least a portion of the first connection opening. It is preferably possible to completely surround it, and it may have the shape of an O-ring.

[0022] To further contribute to particularly good sealing for use in vacuum environments or cleanrooms. Furthermore, the elastic element according to the present invention is for a second connection for supplying a pressure medium to a second pressure chamber A second connection seal may be provided, which seals the second connection. Preferably, the edge of the second connection seal shall at least partially cover the second connection opening. Preferably, it is possible to completely enclose it and may have the shape of an O-ring. Particularly preferred Furthermore, the edge portion can form a connecting projection for the second connecting seal, and the connection The projection forms an undercut at least partially on the edge of the second connection opening. The jigging member can be gripped at the rear by an undercut of the connecting projection of the elastic element. The undercut of the connection seal reinforces the seal to the outside, especially when supplying to the first pressure chamber. This reduces the risk of the second connection seal lifting off the flat surface of the housing during the process. Furthermore, the undercut avoids the need to use sealant (adhesive) in this area. Such sealants can have adverse effects on vacuum or cleanroom environments.

[0023] To further contribute to particularly good sealing for use in vacuum environments or cleanrooms. Furthermore, the housing member or apparatus according to the present invention is for receiving an O-ring, Preferably, it may have a circular groove or notch. Groove or notch with O-ring This prevents fluid from flowing in or out through the edges of the housing when the first pressure chamber is operating. The bulge and the first connection seal support the aforementioned functions. Furthermore, vacuum and clean The sealant (adhesive) between the housing halves is omitted, which is undesirable for use in a room. It is possible.

[0024] To enable the clamp to be used in a vacuum or cleanroom environment, even in a high-humidity environment. Therefore, the inventor developed the following series of means, but these means alone can also achieve the above This can be combined with other methods.

[0025] When operating a device under the influence of a liquid medium, especially in the clamping surface area, the liquid medium may be present. There is a possibility of ingress into the housing. As a result of this possibility, during operation, the first of the media Intrusion of liquid occurs into the pressure chamber, which leads to stagnation in the first pressure chamber. Intrusion of a toxic medium can lead to component failure due to leakage (e.g., damage to rubber), contamination of the equipment, and equipment This leads to a deterioration in response time. The inventors believe that the ingress of liquid media is mainly due to the housing components of the device. In particular, small gaps present in the transition between the two clamping elements or clamping surfaces of the housing member. We recognize that this is caused by a gap. During the opening process, for example, compressed air enters the second pressure chamber. By supplying this, the second pressure chamber is expanded. At the same time, the first pressure chamber is ventilated. The movement of an elastic element (for example, a rubberized spring plate) causes air to move. The liquid medium is pushed out from the first pressure chamber and subjected to an attractive force through the first pressure chamber. As a result of the ingress into the first pressure chamber, there is usually a persistent small leak, especially into the second pressure chamber. As long as this occurs and the second pressure chamber is expanding, a constant flow of the liquid medium is brought about. This effect strengthens the suction action, leading to faster device failure or premature malfunction of the device. Harm will occur.

[0026] Given this background, the inventor has a projection on the side of the elastic element facing the first pressure chamber. By attaching a sealing element, this suction action is interrupted or suppressed. It was recognized that the above-mentioned failures or malfunctions could no longer occur in the device. In particular, the means Therefore, the fluid connection between the first pressure chamber and the transition portion of the housing member or clamp element is, The opening and closing function or its dynamics can be prevented without impairing it. In the elastic element according to the present invention, Two sealing elements are positioned on the second side surface of the annular spring plate, and the second sealing element The element has an inner projection in the region of the inner edge of the annular spring plate of the elastic element, and the annular The spring plate has an outer projection in the region of its outer edge. These two projections on the part and outer edge generally correspond to the opposing second elastic element or housing. It is placed on the inner wall and used to form a second pressure chamber. Therefore, these two Each of the protrusions may preferably have a support surface. In accordance with the inventor's above understanding, The elastic element relating to the light is the other (first) spring plate which may be facing the first pressure chamber. 1) has a (first) sealing element on its side, the sealing element forming a first projection, The projection therefore protrudes into the first pressure chamber, and in the first pressure chamber, the first pressure chamber and the Howe It is suitable for at least preventing fluid connection with the transition portion of the jigging member.

[0027] The first projection is preferably located between the inner and outer edges of the annular spring plate. It is formed, and particularly preferably, the first projection is such that the clamping action is directed inward or outward. Depending on whether it is facing sideways, an annular s The first projection is formed in the region of the inner or outer edge of the pulling plate. Alternatively, it may be attached to the transition area of ​​the housing member or clamp element, and the first pressure chamber Attached to the first side of the annular spring plate to be suitable for protruding inward. It is being done.

[0028] Therefore, the first projection protrudes from or extends from the surface of the first sealing element. Preferably, the first sealing element is integral with and / or integrated with the first projection. It is formed by [something].

[0029] According to a preferred embodiment of the elastic element, the first sealing element is further preferably the first side Preferably, the annular spring plate on the side opposite to the edge where the first projection is located. In the edge region, there is a second projection, and the second projection is connected to the first pressure chamber and the housing It serves to further interrupt or prevent fluid connection with the transition portion of the clamping member or clamping element. Yes, they are.

[0030] According to a preferred embodiment of the elastic element, the first and / or second sealing element is a spring It is vulcanized on a rate, which results in particularly good fixation.

[0031] Preferably, the first projection and / or the second projection each have a housing of any shape. To establish contact on the inner wall of the ring, at least a partially rounded surface is used. This may result in the blocking or interruption of the fluid connection as described above.

[0032] According to a preferred embodiment of the housing member or device, the housing member is a housing member The inner surface has a depression or recess, and preferably the depression or recess is in a shape that makes contact The surface of the first or second protrusion is complementary to it, thereby making the aforementioned contact particularly effective. It becomes effective (sealed).

[0033] The inventors have found that both the first projection and the second arbitrary projection of the first sealing element are, In order to prevent or avoid the outflow of the pressure medium (especially gas) that may be supplied to the first pressure chamber, We recognize that it is suitable. This allows for clamping in a vacuum or cleanroom. In addition to its use, it makes it easier to use in high-humidity environments.

[0034] For use in high-humidity environments, vacuums, or cleanrooms, the housing components include vacuum Alternatively, to avoid the release of rust into the cleanroom, preferably a suitable material that is resistant to corrosion, Preferably, a material made of steel can be used.

[0035] The methods described herein, individually or in combination, in a vacuum and / or cleanroom: Furthermore, even in high-humidity environments, it can be reliably operated without adversely affecting the dynamics of the clamp's opening and closing. A functional clamp may be provided.

[0036] In a brief explanation, when describing features not described in the claims, these The characteristic is important in the sense that it must be included in the claims. However, these features are particularly important preferred realizations of the subject matter described in the claims. Yes, and can be combined with any of the claims, and optionally combined with each other. It is also possible to do so. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0038] Components shown in multiple drawings are given the same reference numeral.

[0039] This disclosure relates to annular elastic elements and housings for pneumatic clamps and / or brake devices. A clamping member and a pneumatic clamp and / or brake device having such annular elastic elements. And, regarding that.

[0040] In this specification, "clamp" refers to a device or "clamping device", "clamping force" or " When referring to the "clamping" process, use the "brake" device or "brake device" or "control" The processes of "powering" or "braking" are also included.

[0041] Figures 1A to 5A and Figure 8 show a housing 3 including two housing members 3a and 3b, The present invention provides a housing 3 comprising at least two annular elastic elements 1a, 1b, which are disposed within the housing 3. A schematic cross-section of such a clamping device 10 according to the present invention, which has a spring 1, is shown. They are doing it.

[0042] In this case, the clamping device 10 according to the present invention includes the following: the first elastic band according to the present invention Elastic element 1a and a second elastic element 1b according to the present invention; first housing member 3 having an inner surface Housing 3 including a and a second housing member 3b having an inner surface, Members 3a and 3b, and the inner surfaces of housing members 3a and 3b, both are inside the internal space of housing 3. Housings 3;1 are arranged relative to each other and fastened to each other to partition the space 13. The clamp element 8 is as described above, and each clamp element 8 has a clamping surface 7. 8; A spring arranged in the internal space 13, including a first elastic element 1a and a second elastic element 1b 1, and elastic elements 1a, 1b are such that the first pressure chamber 4 in the internal space 13 is elastic element 1 The internal space 13 is formed between a, 1b and the inner surfaces of housing members 3a, 3b. It is located in the first pressure chamber 4, which is used for ventilation and supplying to the housing 3. It is possible to apply positive pressure to the pressure medium, and the first elastic element 1a has a first side surface that It is clamped within the internal space 13 while facing the inner surface of housing member 3a. The second elastic element 1b has its first side surface facing the inner surface of the second housing member 3b. In this state, it is clamped in the internal space 13, and the spring 1 causes the first pressure chamber 4 to ventilate. When ventilation occurs, or when positive pressure is applied to the first pressure chamber 4, the elastic elements 1a and 1b It is configured so that the bending of at least one spring plate is variable, and this Therefore, the device 10 ensures that the object 5 to be clamped is separated from one or more clamping surfaces 7. In the open state, at least one clamping surface 7 transmits clamping force and / or braking force to the object 5. A spring that switches between the closed state and the closed state. The apparatus 10 according to the present invention further includes the aforementioned This includes means, which ensure the reliable operation of the device in a vacuum and / or cleanroom. This becomes possible. These means will be explained in more detail in relation to Figures 6 to 12. .

[0043] Figures 1A, 1B, 4A, and 4B show the clamping surface 7 of the clamping element 8 against an object. The clamping device 10 in a closed state is in contact with the circumference of 5. The clamping element 8 is Also called a clamp lip. The clamp element 8 is attached to the other parts of housing members 3a and 3b. It may be formed integrally with the material, or structurally separate from other members of housing members 3a and 3b. The components may be separated into individual parts.

[0044] The clamping force or clamping action of the clamping surface 7 on the object 5 to be clamped is, Two vectors that form the radii of the shaped elastic elements 1a, 1b or the annular recess 11, respectively. This occurs in the clamp plane that is thus formed (see Figure 5A). The axis 9 is annular in this case. It extends through the center point of the ring of the described member, and therefore the main shaft of the clamping device 10 They may also be called and may extend perpendicular to the clamp plane. In this specification, "inside" and "outside" When referring to the projection, edge, or end of ", the inner edge, projection, or end corresponds to the outer edge It is closer to the axis 9 than to the edge, projection, or end. The same can be applied to other components.

[0045] The clamping device 10 may be formed to be rotationally symmetrical around the spindle 9. 9 is located approximately or precisely at the center of the opening of the clamping device 10 (opening 14 in Figure 5B). ) may extend through. In Figures 1A and 4A, the object 5 to be clamped is, for example, a machine or The table's rotatable shaft is positioned within the opening 14, and therefore, the clamp The clamping force of the clamping device is half the force directed toward the spindle 9 (perpendicular to the spindle 9) within the clamping plane. It is directed radially inward. In Figures 1B and 4B, the object 5 to be clamped is... It is located outside the clamping device 10, and therefore the clamping force of the clamping device is, It is directed radially outward (perpendicular to the principal axis 9) so as to move away from the principal axis 9 in the lamp plane. It is.

[0046] In Figures 1A, 2A, 3A, and 4A, the clamping element 8 is connected to the spring 1 and the opening 14 or the main shaft. It is located between 9. On the other hand, in Figures 1B, 2B, 3B, and 4B, the clamped Since object 5 surrounds the clamping device 10 at least partially, the clamping element 8 It is located between object 5 and the opening 14 or the main axis 9. (Figures 1B, 2B, 3B, 4B) So, instead of the object 5 to be clamped, a part that at least partially fills the opening 14 It is possible to introduce the material into the opening 14, and the main shaft 9 extends through this member.

[0047] In each of Figures 1A to 5A, the spring 1 is located inside the housing 3 of the clamping device 10. It is clamped between two contact surfaces (101 and 102 in Figures 5C and 5D), and the two contact It extends between the contact surfaces. In the initial state when the device 10 in Figures 1A to 2B is not pressurized, Spring 1 is slightly bent so that it is fixed inside housing 3 in that state. The same can also be applied to other states of the device 10, and the bending of spring 1 The degree depends on the state of the device 10. If the device 10 is in a state where the spring 1 is bent... In a state where it is bent (for example, a state where it is more bent than the initial unpressurized state such as the open state) In this case, the ventilation of the inner pressure chamber 2 and the ventilation of the outer pressure chamber 4 of spring 1 cause spring 1 to half While pressing the radial contact surface, spring 1 relaxes at least partially, and the gap between them becomes slightly As it expands, the housing 3 expands to the area of ​​the clamp element 8 or the clamp surface 7. It deforms elastically, and the clamping surface 7 thereby comes into contact with the object 5, firmly clamping the object 5. To achieve this, it is pressed against object 5 with a (predetermined) clamping force. As shown in Figures 1A and 1B. Object 5 is tightly clamped, and the clamping device 10 is in the closed position. In the closed state, the spring 1 is partially relaxed in order to be fixed inside the housing 3 in that state. It's okay if it's slightly bent even after that.

[0048] In this case, the clamp element 8 may be an elastic element such as a spring fork, The elastic element is (slightly) bent in the initial, unpressurized state of the device 10. Due to the elasticity of element 1, for example, in the initial state without pressure, the restoring force of elastic element 8 and the b By bending the spring fork 8 until equilibrium is achieved with respect to the elasticity of Ne 1, the spring The sexual element is brought from its initial relaxed position to a position under tension. In this configuration, the clamp surface 7 can press against the object 5.

[0049] In the closed state, compressed air (for example, at 4 bar or 6 bar) is added to the outer pressure chamber 4. By supplying it, there is any possibility of increasing the clamping force by a predetermined value. This is shown in Figures 1A and 1B, with an optional additional compressed air pump (booster) 6 and an external The diagonal lines (compressed air) within the side pressure chamber 4 suggest this. The outer pressure chamber 4 is Howe The opening of the sing 3 is connected to the air connection part I (also called "closed") Often, a compressed air pump 6 is connected to the air connection part I.

[0050] This allows, for example, the braking of the supplied object 5 (in an unpressurized state). A switch is made between a controlled movement and a complete clamping of the object (under sufficient pressure). This makes it possible to operate the device 10.

[0051] Here, two pressure chambers 2 and 4 are shown and explained as examples, but the clamping device 1 0 operates with only one pressure chamber, which could be, for example, the inner pressure chamber 2 or the outer pressure chamber 4. It is also possible to do so.

[0052] Figures 2A and 2B show the clamping device 10 of Figures 1A and 1B in the open state, respectively. As shown, in the open state, the clamp surface 7 does not contact the circumference of the object 5, or does not contact the circumference of the object 5. They are separated. The inner pressure chamber 2 is connected to the air connection part II by the opening of the housing 3. It is often connected to an air connection part II (also called an "open" connection), and the compressed air pump 6 is connected to the air connection part II. It's OK to be connected.

[0053] Compressed air (e.g., 4 bar or 6 bar) is supplied to the inner pressure chamber 2 by the compressed air pump 6. By supplying air and venting the outer pressure chamber 4, the spring 1 is brought to the closed state shown in Figures 1A and 1B. Compared to being bent or stretched more strongly (convex), the distance between the contact surfaces of spring 1 or 2 is the radius It is shortened in that direction. To release the clamp, the clamp surface 7 is lifted away from the object 5. Object 5 can move freely (for example, it can rotate around axis 9 or move in a straight line along axis 9). (It is movable to the target), and the clamping device 10 is open.

[0054] The device 10 can be switched between a closed state and an open state in both directions.

[0055] Such a pneumatic clamp 10 has many advantages compared to a hydraulic clamp.

[0056] The combination of an elastic member, in this case a spring 1 including elastic elements 1a and 1b, and compressed air By using this, for example, a very short reaction time can be obtained when switching between the open and closed states. This also provides secure clamping of object 5. Spring 1 is preferably shown in detail in Figure 5. The spring 1 and the plate are plate-shaped, and the two overlapping elastic elements 1a and 1b are plate-shaped. The plates 1a and 1b form an inner pressure chamber 2 of the spring 1 between plates 1a and 1b. As shown in Figure 5, it may be annular and optionally have additional radial slots. This makes it possible to change the inner diameter with particularly small forces. Elements 1a and 1b, in order to establish the necessary sealing for compressed air, at least the area of ​​the slot The region may be coated with rubber. Elastic elements 1a and 1b generally have pressure resistance. It is configured to be elastically bendable and is located within the housing 3 of the clamping device 10. It is formed such that an inner pressure chamber 2 is formed between the elastic elements 1a and 1b inside the spring 1, Elastic elements 1a, 1b and housing 3 or housing members 3a, 3b of clamp device 10 An outer pressure chamber 4 is formed between them. Figure 5 shows a clamping device similar to those in Figures 1A and 2A. This is a diagram showing the number 10 in three dimensions.

[0057] As shown in Figure 1A, ventilation or supply of compressed air to the outer pressure chamber 4 and the inner pressure chamber 2 By ventilation, the spring 1 is at least partially relaxed, and the object 5 to be clamped, in particular This applies a clamping force around shaft 5. This blocks energy or pressure. In that case, object 5 will be clamped, or shaft 5 will stop immediately, and therefore safe A clamp is provided. Such a pneumatic clamp 10 can withstand several hundred Nm depending on its dimensions. A maximum holding torque of several thousand Nm can be obtained, and the holding torque is as shown in Figure 1A. As indicated by the pressure pump 6 (booster), compressed air is supplied to the outer pressure chamber 4. It is possible to further increase this by supplying additional components. In this case, the booth To provide several times the holding torque obtainable without using a torquer, several bar (e.g., 4 bar) is required. Compressed air at r or 6 bar is sufficient. At this time, switch the open / closed state of clamp 10. When this happens, a slight lateral bend (perpendicular to the longitudinal axis) of plates 1a and 1b causes pre-tension Large bullets can be used to clamp or release the clamping device 10 to which pressure has been applied. The fact that it generates force is utilized. Therefore, in the rapidly rotating machine shaft 5 Even if present, it allows for secure clamping and release.

[0058] In the case of pneumatic materials, the cost and assembly costs are lower compared to hydraulic materials, and compressed air No additional costs are incurred for cleaning the equipment after use. The overall dimensions can also be reduced because the required clamping force can be applied. To achieve this, the spring has a small lateral bend and a small longitudinal extension of the spring (longitudinal direction). A small change in the extended portion (and therefore a small volume of the pressure chamber) is sufficient. be.

[0059] In the case of pneumatic clamps, in principle, passive clamps are used as shown in Figures 1A to 2B. A distinction can be made between the clamping device 10 and the active clamping device 10 shown in Figures 3A to 4B. .

[0060] Spring 1, in its initial unpressurized state, is bent (laterally) with different strengths. Often, and therefore to different degrees, it can be shortened radially. The inner surface of housing 3 is bullet Is it possible to adapt to the bending of structural elements 1a and 1b, or is it possible to determine the bending? The stopper surfaces corresponding to the elastic elements 1a and 1b are, for example, provided by the inner wall of the housing. The inner wall of the housing can be formed with respect to the (e.g., convex) bending of the elastic elements 1a and 1b. They may be formed complementaryly (for example, concave).

[0061] In the passive clamping device 10, the spring 1 is normally slightly in its initial, unpressurized state. It is elastically bent (for example, convex) or pretensioned, The lamp device 10 may be closed (Figures 1A and 1B). The clamp device 10 is closed by the internal pressure Chamber 2 can only be opened by a force acting from the inside, through the supply of compressed air. (Figures 2A and 2B). In most cases, spring 1 is slightly bent in its initial, unpressurized state. Therefore, in the case of clamping or when the pressure drops, the spring 1 stores The elasticity provided by the energy is used to clamp object 5, and the clamping force This is transmitted to object 5, which is to be clamped.

[0062] In the active clamping device 10, the spring 1 is in an initial state where it is not pressurized (Figures 3A and 3B). In this case, the clamping force is stronger than that of a passive clamping device, and especially stronger in the lateral outward direction. Because it is curved in a convex shape, the distance between the two radial contact surfaces becomes small, and clamp device 1 0 represents the open state. No clamping force acts on object 5 through the clamp surface 7. Since surface 7 does not contact object 5, or is separated from object 5, the object is free.

[0063] Due to the plastic deformation of elastic elements 1a and 1b, spring 1 is pressurized within the same housing 3. In the initial state, the clamping force is stronger laterally outward than in the case of a passive clamping device. It can bend and therefore can be significantly shortened in the radial direction. In the initial state, these small radially extending portions of the elastic elements 1a and 1b are pressurized. This can result in the clamping device 10 being in an open state in its initial state. However, since the elastic elements 1a and 1b are elastically bent and pressed against the contact surface, the spring is how It is fixed to the jigging. The internal space or recess of the housing is plastically deformed in the initial state. This allows for greater curvature to be accommodated.

[0064] As shown in Figures 4A and 4B, in order to move the clamp to the closed position, an external clamp is required. The ramp force needs to be actively induced. Here, compressed air is supplied by the compressed air pump 6. Compressed air is introduced into the outer pressure chamber 4, and compressed air is supplied to the spring 1 from the outside, thereby, Spring 1 actively relaxes, the curvature of spring 1 decreases, the distance between the two contact surfaces increases, and the housing Since the clamp 3 is elastically deformed in the region of the clamp element 8 or the clamp surface 7, the clamp surface 7 It contacts object 5, applying a clamping force to object 5, thereby making object 5 firmly clamped. The active clamping device 10 is closed.

[0065] Depending on the application field and prescribed safety regulations, an active or passive clamping device 10 may be used. In particular, when a secure clamp is desired, a passive clamping device is generally used. In such pneumatic passive clamping systems, the device is assembled to correspond to the entire device. When assembling, it is possible to generate the predetermined clamping force even when no pressure is applied. This clamping force is applied to the object 5 to be clamped. Positive or negative pressure is applied. By doing so, the force transmitted to the object is increased, decreased, or completely stopped. This makes it possible, which opens up a variety of applications. In contrast, with a clamping device... Firstly, when attempting to perform an intentional work process such as tool changing, generally, A clamping device is used.

[0066] As shown in Figure 5A, the housing 3 of the clamping device 10 according to the present invention has two housings The housing members include 3a and 3b, and these housing members are fastened to each other by fastening means such as screws. It is assembled, and in the assembled state, the two housing members 3a, 3 b defines an internal space 13 between housing members 3a and 3b within housing 3. Within the internal space 13, the spring 1 is arranged together with the annular elastic elements 1a and 1b according to the present invention. As shown in Figures 5A to 5D, housing members 3a and 3b each have recesses 1 1 is defined, and the recess 11 is similarly annular, and to receive the annular elastic elements 1a, 1b It is used. At least a portion of the first contact surface 101 of the housing member is an annular recess 11 It is possible to extend perpendicularly to the radial direction R of the housing member, and / or the second of the housing member A portion of the contact surface 102 can extend perpendicularly to the radial direction R of the annular recess 11. ru.

[0067] An opening 14 (Figure 5B) extends through the center of the housing 3, and the opening 14 An object 5 to be clamped, such as a shaft, may be introduced into the opening. It can extend up to 360° around it, and at least one is called the clamp plane. The object 5 is at least partially surrounded by two planes. The central axis 9 of the clamping device is It passes through the center of the opening 14 and extends perpendicular to the clamp plane. Figures 1A, 2A, and 1A are shown. In the clamping device shown in Figures 3A, 4A, and 5A, the main shaft 9 is aligned along its longitudinal axis. It runs through the center of the to

[0068] One or more clamping surfaces 7 exist along the circumferential direction of the housing 3 or the opening 14. The clamp surface 7 is the area where the housing 3 is elastically deformed in the region of the clamp element 8 or the clamp surface 7. In this case, a clamping force is applied to the outer circumference of object 5, thereby clamping object 5. This can be done. The clamping device 10 is applied to the object 5 to be clamped, and the object 5 is not damaged. To open and close effectively without taking any risks, the clamping force must be applied along the clamping surface 7, or to the object. It is desirable that the clamping force be distributed symmetrically along the circumference of body 5. If this occurs, object 5 may be damaged. Preferably, one or both contact surfaces 10 1, 102 are formed in a circular shape within the clamp plane. Preferably, the clamp surface 7 is It is formed in a circular shape within the ramp plane. The clamp element 8 may be formed in an annular shape. Each of the annular or circular members described in the specification, individually or in combination, is part of the main shaft 9. The center point can be the point of intersection with the clamp plane (for example, the center point of the opening 14). .

[0069] Figure 5B shows the housing member according to the present invention (in this figure, the upper housing member 3a in Figure 5A). The following embodiment is shown, in which the housing member 3a clamps the annular elastic element 1a The housing member 3a has an annular recess 11 for the inner surface defined by the recess 11. (See 105 in Figure 7) The annular recess 11 is preferably annular to the housing member. The opening 12 is defined, and the annular opening is defined between the first annular edge 12a of the housing member and the housing It is formed between the second annular edge portion 12b of the zing member. The elastic element 1a is formed between the first ring It is possible to clamp it between the oval edge portion 12a and the second annular edge portion 12b.

[0070] The elastic element 1a has an opening with its first side surface (see 16c in Figure 6C) facing the inner surface. When inserted into the recess 11 through 12 and clamped in the recess 11, the inner surface and elastic element 1a A first pressure chamber 4 is formed between the two. In this case, the elastic element according to the present invention is as mentioned at the beginning. The system has means to ensure that the components are used reliably in a vacuum and / or cleanroom. This makes it possible. The means will be described in more detail in relation to Figures 6 to 12.

[0071] As shown in Figures 5C and 5D, the illustrated elastic element 1a of the spring 1 is a housing member Extending from the first contact surface 101 within 3a to the second contact surface 102 within the housing member 3a And it can come into contact with the second contact surface 102. At this time, the first contact surface 101 is open. When viewed from the center point of part 14, it is positioned radially outward from the second contact surface 102.

[0072] Figure 5C shows the portion of the housing member 3a shown in Figure 5B, and the upper part of the spring 1 Rate 1a collides with the first contact surface 101, and preferably makes contact. Figure 5D is shown in Figure 5B. This shows the portion of the housing member 3a shown, and the upper plate 1a of the spring 1 is the second It collides with the contact surface 102 and preferably makes contact. However, if the elastic element 1a is 1 or more Between the contact surfaces 101 and 102, there are one or more additional members in the radial direction. In addition, it is possible for the elastic element 1a to exert elasticity on the contact surfaces 101 and 102 via the said member. That is the case.

[0073] As is clear from Figures 5B and 5D, there is an elastic element between the inner surfaces of the housing member 3a. 1a is clamped in the recess 11. Each plate of spring 1 is connected to two contacts The ends of the contact surfaces 101 and 102 come into contact with the stoppers 112 and 122, and therefore During assembly, until it can no longer be introduced into the recess 11, the inner surface of the housing member 3a Along the direction of the main axis 9 of the clamping device 10, each attached through the opening 12 It is introduced into the recess 11 of the housing member. The elastic element 1a is in the clamping plane or annular The radially extending portion of the recess is an extension of the internal space defined by the housing member. Because it is larger than the portion, plate 1a is bent in its initial, unpressurized state. Alternatively, pretension may be added.

[0074] In Figures 6A to 6C, the present invention is for use in a vacuum and / or cleanroom. Embodiments of the means of the elastic element, and any means for use in high humidity environments, It is shown in detail.

[0075] Figure 6A shows an annular elastic element for a clamp and / or brake device 10 according to the present invention. The diagram shows 1a and 1b, and the elements 1a and 1b include: an annular spring plate 16 an annular spring having a first annular surface 16c and a second annular surface 16d Rate 16; any (first) sealing element 17, preferably a spring plate (First) seal element 17 positioned on the first side 16c of 16; (Second) seal The seal element 15 is the (second) seal element 15 on the second side of the spring plate 16 The (second) sealing element 15 is positioned on 16d and inside the annular spring plate 16. An inner projection 15a is formed in the region of the side edge 16a, and the outer edge of the annular spring plate 16 An outer projection 15b is formed in the region of part 16b, and the inside and / or of the (second) sealing element 15. The outer projections 15a and 15b each form bulges 15c and 15d, at least partially. (Second) sealing element 15. Preferably, any (first) sealing element 17 is first A projection 17a is formed.

[0076] Figures 6B and 6C show the first projection 17a on the inner edge 1 of the annular spring plate 16. This indicates that it is formed between 6a and the outer edge portion 16b, and here, as an example, the first The projection 17a is located on the inner edge 16a or outer edge 16b of the annular spring plate 16. It is formed in the region.

[0077] Figures 6A and 6B further show that the first sealing element 17 is preferably an annular spring In the region of the outer edge 16b of the rate 16, an arbitrary second projection 1 is placed on the first side surface 16c This indicates the formation of 7b.

[0078] The projections 15a, 15b, 17a, 17b of the first and / or second sealing elements 15, 17 It may be at least partially annular and may extend annularly around axis 9. First and / Alternatively, the projections 15a, 15b, 17a, and 17b of the second sealing elements 15 and 17 are, respectively It can be fixed to the spring plate 16 and is preferably vulcanized, or spring It may be removably positioned from the ring plate 16, preferably as an O-ring.

[0079] Figures 6A and 6C further show that the longitudinal axis of the first projection 17a of the first sealing element 17 is ...extending perpendicularly to the first side surface 16c of the spring plate 16. It is showing.

[0080] As shown in Figures 6B and 6C, the inner projection 15a and / or outer projection of the second sealing element 15 Each lateral projection 15b has at least partially flat surfaces 15e, 15f, and is flat The surfaces 15e and 15f are, for example, (inside) to partition and seal the second pressure chamber 2. ) It functions as a support surface for the housing wall or other elastic elements. These figures further The inner and / or outer protrusions 15a and 15b of the second sealing element 15 are each small It has also been shown that they form bulges 15c and 15d that extend partially in the radial direction. Yes, they are.

[0081] Preferably, as shown in Figure 6B, the outer projection 15b of the second sealing element 15 has a valve. The 15d extends radially outward, preferably beyond the outer edge 16b of the spring plate 16. It extends radially outward. Preferably, the bulge 15d is close to the flat surface 15f. Or they are adjacent. Preferably, the flat surface 15f merges with the bulge 15d.

[0082] Preferably, as shown in Figure 6C, the inner projection 15a of the second sealing element 15 has a valve. The 15c extends radially inward, preferably beyond the inner edge 16a of the spring plate 16. It extends radially inward. Preferably, the bulge 15c is close to the flat surface 15e. Or they are adjacent. Preferably, the flat surface 15e merges with the bulge 15c.

[0083] The first sealing element 17 and / or the second sealing element 15 are, individually or together, elastic The material may be made from rubber or other suitable material, and the sealing element may be a spring It is fixed to the ing plate 16 (for example, by vulcanization).

[0084] Figure 7 shows housing members 3a and 3b according to the present invention. The present invention has an advantageous and preferred fit for the elastic elements 1a and 1b.

[0085] The housing members 3a and 3b are annular for clamping the annular elastic elements 1a and 1b. The recess 11 is the first ring of the annular opening 12 of the housing members 3a, 3b. The annular recess 11 forms the first annular edge 12a and the second annular edge 12b, and the annular recess 11 is formed by the first annular edge 1 The inner surfaces 105 of the housing members 3a and 3b are defined between 2a and the second annular edge portion 12b. The inner surface 105 has a first inclination 103 (or long chamfer) in the region of the first annular edge 12a. The inner surface 105 forms a second inclination 104 in the region of the second annular edge 12b. Or a long chamfered portion) is formed, and the inclined portions 103 and 104 have annular openings 12 that are first and second It is positioned to expand toward the edges 12a and 12b.

[0086] The inner surface 105 can form a first contact surface 101 and a second contact surface 102. The first contact surface 101 and the second contact surface 102 are elastic elements 1a and 1b according to the present invention. The spring plate 16 is configured to clamp between them, and the first inclination 103 is positioned between the first contact surface 101 and the first annular edge 12a, and the second inclination 1 04 is positioned between the second contact surface 102 and the second annular edge portion 12b. Elastic element 1a and 1b are clamped within the recess 11 with the first side surface 16c facing the inner surface 105. If so, bulges 15c and 15d are preferably sealed with inclined surfaces 103 and 104. Make contact with them.

[0087] As shown in Figure 7, the first contact surface 101 has a first inclined surface 103 (or a long chamfered portion) It may form or merge with the first inclination 103, and / or the second contact surface 10 2 forms a second inclination 104 (or a long chamfered portion), or the second inclination 104 They may merge, and the inclined surfaces 103 and 104 each have an annular opening 12 or recess 11. The parts are aligned to expand toward the first and second edges 12a and 12b. This is preferable (see Figures 7 and 5B). The force that bends the clamp element 8 is transmitted to the clamp element 8 by the second sealing element 15. This is largely avoided, and rather the spring plate 16, or the inner edge portion 16a, is the object The force for clamping or braking 5 is primarily transmitted to the clamp element 8 and the clamp surface 7. This protects the second sealing element 15, making the opening and closing process of the device more reliable. Yes.

[0088] Bulges 15c and 15d block the space between inclines 103 and 104 and are in contact with inclines 103 and 104. It is provided for contact. The bulges 15c and 15d are adjacent to the housing member 3a. This is advantageous for the sealing of the first pressure chamber 4 with respect to the gap in the transition of the clamp element 8 of 3b. The bulge at the edge of the housing, having inclined surfaces 103 and 104, during the operation of the first pressure chamber 4. Furthermore, it has the advantage that little to no medium flows in or out through the edges of the housing.

[0089] On the other hand, the flat surfaces 15e and 15f are such that when the pressure medium is supplied to the second pressure chamber 2, To increase resistance to the permeation of pressure media (especially gases). The flat surfaces 15e and 15f are To reduce or prevent overflow of the medium between the first pressure chamber 4 and the second pressure chamber 2. The flat surfaces 15f and 15e are bulges 1 against the inclined surfaces 103 and 104 of the housing. This supports the displacements of 5c and 15d, and therefore the action of the bulge described above. This support is shown in Figure As described in relation to 6B and Figure 6C, a flat surface 15e or 15f is attached This is particularly noticeable when adjacent to and / or converging with Ruuji 15c or 15d. Therefore, the flat surface and the bulges attached to it are a combination of features that work synergistically. They form a cluster, but may also exist individually. When considering vacuum operation, each sealing element 17a And 17b are considered additional barriers and help to seal the first pressure chamber 4 against the environment. .

[0090] The housing members 3a and 3b have preferably circular grooves or for receiving the O-ring. It may have a notch 110. The groove or notch 110 is in the region of the first annular edge 12a. or between the outer edge 100b of the housing member and the first contact surface 101 or recess 11 And preferably completely surround the housing members 3a and 3b along the periphery of the housing member. The groove or notch 110 can be an alternative or additional feature of the second annular edge 12b. In the region, or between the inner edge 100a of the housing member and the second contact surface 102 or recess 1 Between 1 and the housing member, preferably along the circumference of the housing member 3a , can surround 3b.

[0091] To ensure additional preferred sealing for use in high-humidity environments, the first seal Elements are provided. Elastic elements 1a and 1b have a first side surface 16c facing the inner surface 105. When clamped in the recess 11 in this state, the first projection 17 of the first sealing element 17 a preferably seals with the first portion of the inner surface 105 of the housing members 3a and 3b. Contact is made. The first part has a recess or recess 106 in the housing members 3a, 3b. This is possible. Preferably, the surface shape of the first projection 17a and the first portion 106 is particularly To establish a contact that effectively seals, they are at least partially complementary. Elements 1a and 1b are clamped into the recess 11 with the first side surface 16c facing the inner surface 105. If the first sealing element 17 is installed, the second projection 17b of the first sealing element 17 is positioned on the housing member 3a. It preferably comes into contact with another part of the inner surface 105 of 3b in a sealed manner. This other part is The wodging members 3a and 3b may have recesses or indentations 107. Preferably, the second The surface shape of the projection 17b and portion 107 establishes contact that seals particularly effectively. Therefore, they are at least partially complementary. Each of the two projections 17a and 17b is particularly In the transition region between the two adjacent housing members 3a and 3b, the first pressure chamber 4 and the housing It obstructs or completely blocks the fluid connection between the zing and its surroundings.

[0092] Preferably, the housing members are made of a corrosion-resistant material.

[0093] Figure 8 shows a clamp and / or brake device 10 according to the present invention. For example, a device 10 having an inward clamping action is shown in Figures 1A, 2A, and 5. It is being done.

[0094] In Figure 8, the first sealing element 1 of at least one of the elastic elements 1a and 1b The first projection 17a of 7 is on the inner surface 10 of one of the housing members 3a and 3b. Preferably in contact with the first part of 5 (e.g., 106) in a sealing manner, thereby the The fluid connection between the region of pressure chamber 4 and the transition between housing members 3a and 3b is at least This contact is blocked. This contact is blocked in the gap of the transition between housing members 3a, 3b or clamp element 8. A medium, preferably a fluid or liquid, flows into the housing 3 from outside the device 10 through the device 10. In contrast, it may be at least partially sealed.

[0095] The region of the first pressure chamber 4 is shown in Figure 8 as the first of at least one elastic element 1a, 1b The first projection 17a of the sealing element 17 and the spring of at least one elastic element 1a, 1b Between the outer edge 16b of the ing plate 16, or the first sheath of at least one elastic element It is positioned between the second projection 17b of element 17.

[0096] Any second projection 17 of the first sealing element 17 of at least one elastic element 1a, 1b b is in contact with the second portion (e.g., 107) of the inner surface 105 of the housing members 3a and 3b. The second portion of the inner surface 105 is established, preferably the first contact of the housing members 3a and 3b. It is located between the contact surface 101 and the second contact surface 102. This projection is also located between the first pressure chamber 4 and Fluid connection with the outer region of the clamp element 8 can be reduced. The inner surface 105 is 1 It is possible to have the above-mentioned recesses or depressions 106, 107, and the recesses or depressions 106, 1 The shape of 07 is preferably complementary to the surfaces of the contacting protrusions 17a and 17b.

[0097] When Figures 6, 7, and 8 are combined, the first contact surfaces 1 of each housing member 3a and 3b are shown. 01 forms the first inclination 103, and the second contact surfaces 102 of each housing member 3a, 3b It is clear that a second inclination 104 is formed, and the second sealing element 1 of the first elastic element The bulge 15c of the inner projection 15a of 5 is on the second contact surface 102 of the housing members 3a and 3b. The second inclination 104 of the first elastic element is in contact with the outer projection 15b of the second sealing element 15 of the first elastic element.

Figures 11 and 12 show the elastic element 1a according to the present invention, respectively, as shown in Figure 9. Figure 1b shows a cross-section of the housing members 3a and 3b attached to the housing members 3a and 3b shown in Figure 10. In this case, the elastic elements 1a and 1b are provided for the first connection seal 30 to the first connection part I. The second connection seal 20 contacts the areas of housing members 3a and 3b, and the second connection seal 20 is in contact with the second connection part II Therefore, in the recess 11, so as to contact the areas of housing members 3a and 3b, The inner edge portion 100a of the clamping members 3a and 3b (or the clamping element 8 having the clamping surface 7) and the outer It is clamped between the side edge 100b. By doing this twice, Figures 11 and 1 As shown in 2, two members according to the present invention are prepared and fastened to each other.

For supply, it is used to seal the second connection part II of the clamp and / or the brake device 10. The second connection seal 20 forms a connection protrusion 2 1 along the edge of the second connection opening, and the connection protrusion 21 at least partially, preferably completely surrounds the second connection opening.

[0106] The connection protrusion 21 of the second connection seal 20 forms an undercut 22 at least partially along the edge of the second connection opening, especially to reinforce the seal against the outflow into the environment of the pressure medium. The undercut 22 of the second connection seal 20 reduces the risk that the second connection seal 20 will lift off from the flat surface of the housing, especially when the supply is being made to the first pressure chamber 4. Furthermore, the use of a sealant (adhesive) at this location can be avoided by the undercut 22. Such a sealant can have an adverse effect on a vacuum or a clean room.

The edge portion of the first connection seal 30 at least partially, preferably completely, surrounds the first connection opening.

[0109] The first connection seal 30 may include an O-ring surrounding the first connection opening. The bulge 15d of the protrusion 15b having an inclination 10 together with the first connection seal 30 at the connection portion I ensures that fluid does not flow in or out through the edge of the housing when the first pressure chamber 4 is supplied. In addition, this may eliminate the need for an undesirable sealant (adhesive) between the housing halves. Such a sealant may have an adverse effect on a vacuum or a clean room environment. (adhesive) can be made unnecessary. Such a sealant may have an adverse effect on a vacuum or a clean room environment.
