Definitions
- the invention relates to a line protector ring for an energy supply line on a robot arm, having at least a first partial shell and at least one second partial shell, the partial shells complementing each other when assembled to form a first annular body of the line protector ring, which first annular body has an inner jacket wall which surrounds the energy supply line surrounds when the line protector ring is arranged in its mounting position on the energy supply line.
- the object of the invention is to create a line protector ring for an energy supply line on a robot arm, which can be easily restored with little assembly effort if it is worn out.
- a line protector ring for an energy supply line on a robot arm having at least a first partial shell and at least one second partial shell, the partial shells complementing each other when assembled to form a first annular body of the line protector ring, which first annular body has an inner jacket wall which surrounds the energy supply line surrounds when the line protector ring is arranged in its mounting position on the energy supply line, with the first ring body being arranged on its outer jacket wall Circumferential seat surface on which a one-piece, circumferentially closed second ring body is placed.
- the type of line protector rings in question generally serve to protect a power supply line from substantial damage by keeping the power supply line at a distance from a robot arm. Contact between the energy supply line and the links of the robot arm is only permitted to a certain extent, essentially only on the line protector rings, so that on the one hand there are as few collisions as possible between the energy supply line and the robot arm.
- the energy supply line primarily only comes into contact with the links of the robot arm with its line protector rings.
- the line protector rings can be intended for attachment to the energy supply line.
- One or more line protector rings can therefore be attached to an outer jacket wall of the energy supply line or be attached to a protective tube on the energy supply line.
- one or more line protector rings can also surround the energy supply line only on the circumference, without these being attached directly to the energy supply line.
- the first ring body can generally have an inner jacket wall which surrounds the energy supply line on the circumference when the line protector ring is arranged in its mounting position on the energy supply line.
- One or more line protector rings can be attached, for example, to a ring or pipe socket that surrounds the energy supply line, i.e. H . In such a case, the energy supply line is passed through the ring or the pipe socket.
- the line protector rings also form wear bodies, which are deliberately designed as contact bodies with the links of the robot arm, so that unavoidable collisions, which can also include grinding movements, occur between the energy supply line and the robot arm only with the line protector rings and thus the actual energy supply line, in particular its Protective hose is protected from damage and wear.
- a corresponding energy supply line can, for example, be equipped with one, two or more line protector rings.
- An energy supply line is understood to mean, in particular, an energy line and/or an energy supply that can have lines, such as electrical lines, cold and/or hot water lines, fluid and/or pressure lines to tools that are flanged to the robot arm.
- the energy supply line in particular the energy line and/or the energy supply, can be combined in individual strands or in cable bundles and in particular covered with one or more flexible protective tubes, such as corrugated tubes.
- the line protector rings can be attached to these corrugated hoses, for example.
- the line protector rings In order for the line protector rings to be able to be completely attached and removed from an energy supply line when necessary, even while the energy supply line is mounted on a robot arm, they generally have to be designed in at least two parts.
- the at least two half-shells are usually connected to one another using known fastening means.
- This Fasteners can be screws or rivets, either made of metal or plastic.
- the first ring body can form an inner ring of the line protector ring, which is concentrically surrounded by a second ring body as an outer ring.
- the first annular body comprises at least a first partial shell and at least a second partial shell, the partial shells complementing each other when assembled to form the first annular body of the line protector ring.
- the first ring body has a circumferential seating surface arranged on its outer jacket wall, onto which a one-piece, circumferentially closed second ring body is placed.
- the second ring body is therefore not designed in several parts, but in one piece.
- the second ring body surrounds the first ring body on the circumference from the outside.
- the one-piece second ring body sits on the outer jacket of the first ring body.
- the second ring body forms the part of the line protector ring intended for wear, i.e. H . the actual wear ring.
- the multi-part inner ring merely forms a carrier ring with which the entire line protector ring is attached to an energy supply line.
- the outer ring forms the wear ring, which is designed to ensure that the energy supply line slides over the robot arm with as little friction as possible. to be wear-free.
- the second ring body i.e. H . the one-piece outer ring or the one-piece wear ring is intended for this purpose Unavoidable wear to provide the wear material required for a certain period of time, so that it is reliably or at least largely prevented that the multi-part first ring body, i.e. H . the carrier ring is damaged.
- the outer ring is intended to be worn on the robot arm during normal operation in order to protect the links of the robot arm and to protect the inner ring or to protect the carrier ring from wear.
- the first ring body has a circumferential seat surface arranged on its outer jacket wall, onto which a one-piece, circumferentially closed second ring body is placed, repairing an energy supply line on a robot arm can be carried out more easily, quickly and more cost-effectively.
- the second ring body which forms the actual wear ring, has no gaps or joints due to its one-piece nature. Since there are no gaps or joints on the second ring body, there are no edges or steps which, on the one hand, could be in danger of being subject to increased wear and, on the other hand, the edges or steps could possibly cause increased wear on the surface of the ring body Robot arm could cause.
- Robot arm could cause.
- An omission of Fasteners or Fasteners are also more cost-effective and reduce the number of parts in production.
- the two-part or Multi-part first ring body (carrier ring) remains on the energy supply line and only the worn outer second ring body (wear ring) needs to be replaced. If a worn second ring body is to be removed, it is sufficient to simply remove it in the axial direction from the first ring body, i.e. H . removed from the carrier ring.
- the first ring body, i.e. H . second ring body withdrawn from the carrier ring in the axial direction from the energy supply line or be removed from the corrugated hose of the energy supply line. No tools are then required to create a fastener or to release a connecting means so that the second ring body can be removed from the first ring body.
- the invention also results in a very economical line protector ring, since in the event of wear only the outer second ring body has to be replaced and the first ring body can remain on the energy supply line, i.e. H . can be reused.
- Removing a worn second ring body from the energy supply line is particularly easy because the inside diameter of the second ring body is in any case significantly larger than the outside diameter of the energy supply line due to the size of the first ring body. of the corrugated hose of the energy supply line.
- the one-piece, circumferentially closed second ring body can be clamped in a force-fitting manner onto the circumferential seating surface of the first ring body.
- the one-piece, circumferentially closed second ring body can be made from an elastomeric material. If the second ring body is made of an elastomeric material, it has an internal elasticity of the second ring body itself and no separate clamping means are required.
- the elastomeric material f can be, for example, a polyurethane, a natural rubber or a silicone rubber.
- the elasticity of the second ring body can be adjusted by appropriately selecting a specific elastomeric material for the second ring body.
- the elasticity of the second ring body should, for example, be adjusted on the one hand with a view to ensuring the highest possible adhesion of the second ring body to the first ring body and, on the other hand, with a view to allowing the second ring body to be pulled off as easily (manually) as possible from the first ring body.
- a high adhesive force of the second ring body on the first ring body should ensure that the second ring body remains in place during operation of the energy supply line on the robot arm, when the line protector ring is dragged along Robot arm does not come loose unintentionally, but remains reliably on the first ring body due to the clamping force.
- a slight (manual) removal is intended to ensure that the second ring body can be removed by one person, if necessary, without special tools. manually, can be axially braced from the first ring body, so that the second ring body can be easily removed in the event of wear. a new second ring body can be easily pushed axially onto the first ring body.
- the second ring body can also be made from a solid material.
- the solid material can then in particular be a softer material f than a corresponding material f in a second ring body with a hollow cross section.
- the one-piece, circumferentially closed second ring body can have a circular cross section.
- the circumferential seating surface of the first ring body can be in Art be shaped like a groove.
- the groove then has a radius of curvature that matches the diameter of the second ring body.
- the first ring body is designed to be rotatable around the hose outer jacket wall of the energy supply line
- the first ring body is rotatably mounted on the hose outer jacket wall of the energy supply line
- the cross-sectional contour of the second ring body comprises an arcuate, i.e. H . convex outer wall section and a straight, i.e. H . the inner wall section forming the chord of the circular section-shaped cross section.
- the inner wall section faces the first ring body, i.e. H . the straight inner wall section rests on the circumferential seating surface of the first ring body.
- the convex outer wall section forms the actual wear surface of the second ring body or of the entire line protector ring.
- the assembly of the first ring body and second ring body receives additional axial fixation.
- the recessed groove together with the ring projection also forms a guide in order to be able to ensure the exact mounting position of the second ring body on the first ring body.
- the circumferential seat surface of the outer jacket wall of the first ring body can be designed to simultaneously accommodate at least a first one-piece, circumferentially closed second ring body and at least a second one-piece, circumferentially closed second ring body.
- the circumferential seating surface of the first ring body can therefore be shaped accordingly so that instead of just a single second ring body, two, three, four or even more second ring bodies can be attached to the same first ring body.
- Each of the several one-piece, circumferentially closed second ring bodies can lie in an assigned ring recess of the common first ring body.
- the several ring recesses and the several one-piece, Second ring bodies closed on the circumference can each extend parallel to one another over the circumference of the first ring body.
- the several one-piece, circumferentially closed second ring bodies can be arranged axially spaced apart from one another.
- the first ring body can have fastening means which are designed for rotationally and axially fixed clamping of the first ring body on a hose outer jacket wall of an energy supply line.
