Definitions

  • the invention relates to a nut for a rotating driven screwing device for tightening or loosening screws or nuts, consisting of a head piece made of lightweight material, which is lighter than steel, with a polygonal contact surface for the screws or nuts, which is formed from hard material and from a Coupling part made of lightweight material, which is lighter than steel, with a driving profile for the drive.
  • a screwing device In order to load a screw or nut with the required clamping force, it is operated with a screwing device with manual or power operation, which has an output shaft, on which a so-called nut is rotatably attached, which to the angled attack elements of the head or nut fits a certain screw size and can be replaced depending on the screw size.
  • Known nuts are made of steel so that they occur when tightening or loosening the screws or nuts can absorb high forces without damage.
  • steel nuts are very heavy and their weight can be considerably higher than that of the screwing device itself, so that it is unwieldy and unreasonably heavy when in use. Not only does this hinder handling, but it is also difficult to take along a set of nuts of different dimensions.
  • the polygonal contact surface of the head piece is an inner polygonal profile for plug-in sleeves and an external polygonal profile for pin pins; this depends on the type of engagement elements of the screw head or the nut, ie on whether these are arranged outside or inside.
  • the most common polygonal profiling is the hexagon.
  • the coupling part of the nut is also different in adaptation to the output shaft of the screwing device and can have an angular contact surface on the outside of a shaft or on the inside of a bushing until the teeth are finely divided.
  • a nut made of steel or plastic or other suitable metals according to US Pat. No. 2,651,230 can be equipped with adapters made of tool steel or in the head piece provided with polygonal engagement surfaces Made of plastic and are removable from the head piece.
  • the publication does not refer to a specific combination of materials and measures to stabilize the entire nut made of lightweight material. It is not suitable for use, for example, with a power screw connection device.
  • a tool made of fiber-reinforced plastic is known from WO 84/04721, in which the contact surfaces are formed on a metallic reinforcing element which, with a molded-on profile flange, encompasses the tool opening on the front and on the outer circumference.
  • the "double-walled sleeve" reinforcement element is deep-drawn from a sheet metal and is pressed onto the plastic body.
  • Plastic body and reinforcing element are inextricably linked, so that the reinforcing element cannot be used as an exchangeable adapter.
  • a coupling part for a drive is missing because it is not a nut, but a tool with a molded handle.
  • the invention has for its object to design a nut for a driven screwing device so that it meets high stability requirements with low weight.
  • the hard material of the surface of the head piece has greater hardness and / or toughness than the lightweight material
  • the driving profile of the coupling part is made of hard material of greater hardness and / or toughness than the lightweight material.
  • a nut in which the take-away profiling of the Coupling part with a layer of hard material of greater hardness and / or toughness than the lightweight material is characterized by optimal strength, both with small and large nuts, which are even suitable for impact turning tools.
  • the hard material can be formed from supports which are attached to the head piece and the coupling part in a rotationally fixed manner.
  • the supports can be pressed into the material of the head piece or the coupling part in the form of individual sections or a closed ring, which forms the reinforced polygonal engagement surface or the driving profile.
  • the hard material supports can preferably be provided in a removable ring shape and held by fastening means. These can be formed, for example, by at least one radial pin.
  • the outer circumference of the ring is angularly profiled and engages with a complementary profiling of the head piece or the coupling part together to ensure the torsional strength.
  • the interchangeability of the hard material supports not only increases the life of the nut made of lightweight construction material, it also enables the use of a single nut size for different wrench sizes and different drive shaft diameters, because the hard material supports with suitable external dimensions have different internal dimensions or profiles of the contact surface or the driving profile can have.
  • the engagement surface and the driving profiling can be formed on an inner body made of hard material, which is coated with an outer body made of lightweight material.
  • the hard material inner body can consist of thin-walled steel and the outer body is advantageously formed from plastic material wrapped or cast around the inner body.
  • the inner body can preferably be made of steel and the jacket can preferably be formed from a carbon fiber material or a plastic material of similar special hardness.
  • the head piece and / or the coupling part in the form of a plug-in sleeve on the outside with an annular bandage made of hard material of greater hardness and / or toughness than the lightweight material in order to prevent the nut from breaking out and to stabilize it .
  • the driving profile of the coupling part is an internal profile, it is reinforced with a hard material layer. If it is an external profile, it can be made of hard material itself. In this way, this is also loaded with force Part of the nut achieved reinforcement.
  • the durability of a lightweight nut made of light metal or plastic with two hard material reinforcements is so great that it is even suitable for impact turning tools.
  • the lightweight material can consist of aluminum or aluminum alloys or high-strength plastic and the hard material can be steel or a plastic of greater hardness and / or toughness than the lightweight material.
  • a socket 10 essentially consists of a circular cylindrical head piece 11 made of lightweight material, such as aluminum or a plastic material with which a coupling part 12 made of the same material is firmly connected, preferably in one piece.
  • the coupling part 12 is designed in the example shown as a drive shaft with a circumferential tooth profile 13 made of hard material, such as steel or similar highly elastic and wear-resistant material, and is used for releasable connection to an output shaft of a rotating driven screwing device.
  • the head piece 11 is designed as a thick-walled plug-in sleeve with a circular cylindrical outer circumference and a hexagonal inner circumference.
  • the hexagonal inner circumference forms a receiving surface 17 for a suitable support 15, which consists of hard material such as steel or similar highly elastic and wear-resistant material and which is effective as a reinforcement of the head piece 11 made of lightweight material.
  • the support 15 has the shape of a hexagonal closed ring, the outer circumferential profile and axial extent of which corresponds essentially to the receiving surface 17 and which has a hexagonal engagement surface 14 on the inside for attachment to screw heads or nuts to be tightened or loosened.
  • the pad 15 can be subsequently pressed into the head piece 11 or it can be attached with the aid of suitable adhesives. Furthermore, it is possible to simultaneously press the ring-shaped support 15 or individual support elements, which complement the bent strip course of the engagement surface 14, into the mold during manufacture of the head piece 11.
  • the rest 15 can also be removably arranged in the head piece 11 for exchange for a rest 15 with a different engagement surface 14.
  • a pull-out radial pin can be used to secure it, which engages a piece in the support 15 from the outside through the head piece 11 in order to fix it releasably.
  • the headpiece 11 is further strengthened by a circular ring 16 made of hard material, which preferably has the same nature as the support 15 and which can be pushed outside over the mouth of the headpiece 11 and secured against slipping off by means of at least one pin.
