Definitions

  • the invention relates to a clamping device, in particular a vice, according to the preamble of patent claim 1.
  • clamping devices for example from the EP 0 742 081 A2 , which discloses the preamble of claim 1, have been known for decades and are used successfully for supporting workpieces to be machined.
  • the clamping devices usually have one or two clamping jaws mounted in a housing, between which the workpiece to be machined can be clamped.
  • One of the two clamping jaws can also be provided in a stationary manner as part of a housing of the vice.
  • the clamping jaws are drivingly coupled to a drive spindle, and the rotation of the drive spindle is converted into a linear and synchronous infeed movement of the clamping jaws.
  • the clamping jaws are often attached to a base jaw, for example by means of screws, so that the clamping jaws can be mounted at different positions on the top of the base jaw, so that the specified distance is adjustable.
  • the base jaw is slidably inserted in a linear guide groove, which is incorporated in two side walls running parallel to one another in the housing.
  • the drive spindle has a thread for each base jaw, which engages in an internal thread worked into the base jaws. so that when turning the drive spindle and due to the linear guidance of the base jaws in the housing, an axial displacement of the base jaws relative to the housing in its longitudinal direction.
  • the drive spindle can be actuated manually from the outside, for example by means of a crank, and can be rotated clockwise or counterclockwise depending on the desired positioning of the clamping jaws.
  • the drive spindle is rotatably mounted in the housing and runs coaxially to the longitudinal axis of the housing, ie with an equal lateral spacing to the guide grooves for the base jaws incorporated in the inner wall of the housing.
  • the drive spindle cannot be displaced or moved in the housing because it is mounted on it, but can also perform a rotational movement.
  • the pitches of the thread pairings are identical, but have opposite directions, so that when the drive spindle is turned, a synchronous infeed movement occurs for the base jaws and clamping jaws.
  • a disadvantage of such known clamping devices has been found to be that the threads between the drive spindle and the base jaws are contaminated due to cooling or lubricating fluids and due to chips or other particles occurring during machining of the workpiece, or even the thread pairings become blocked, since the chips that have penetrated block the relative movement between the two threads of the drive spindle and the base jaws.
  • the previously known solutions only provided for the threads to be partially encapsulated, so that one or more of the threads are freely accessible, particularly in the case of an extremely outer or inner position of the base jaws in relation to the housing and its central axis can get into this dirt or chips.
  • the positions of the clamping jaws and the base jaws can be adapted to the geometry of the workpieces to be clamped quickly and without complex retooling measures.
  • the workpieces can have significantly different overall lengths, it is when changing over from extremely small to extremely dimensioned workpieces or vice versa, it is necessary to exchange the base jaws and/or the clamping jaws.
  • such conversion times are time-consuming and since the vices should have a high level of repeat accuracy with regard to workpieces of the same size, new calibrations or measurements of the vice are necessary as a result of these conversion measures.
  • the known clamping devices in particular vices, either have two base jaws or clamping jaws that move synchronously towards or away from one another, or one of the clamping or base jaws serves as a stop and the clamping jaw opposite thereto moves towards it to clamp a workpiece. Consequently, only one workpiece can be reliably held between two clamping jaws in such vices. As soon as several workpieces are to be processed or locked at the same time, they must be of identical length. Workpieces of different sizes cannot be simultaneously clamped in one of the known vices.
  • the drive spindle is permanently encapsulated to be watertight and airtight, and that, on the other hand, the adjustment path of the base jaws or clamping jaws is dimensioned as large as possible in order to clamp workpieces whose designs can be dimensioned completely differently, without time-consuming and complicated retooling being necessary.
  • the clamping device according to the invention should make it possible for the user to hold two workpieces of different sizes in a position-oriented and self-centering manner by the clamping device and for one of the base or clamping jaws to act as a stop for the workpiece to be clamped serves and exclusively the opposite base or clamping jaw is movable relative to the housing.
  • the base jaws can be moved or arranged in different positions in relation to their distance from the central axis of the housing, so that on the one hand workpieces of different sizes can be placed between one of the clamping jaws and the stop and on the other hand one of the clamping jaws as a stop for the workpiece to be machined workpiece is used.
  • the correspondingly required conversion measures can be carried out quickly and easily, since only a few components have to be replaced or one of the base jaws has to be fixed to the housing.
  • the retaining ring attached to the drive spindle is fixed by the fixing block to be fastened to the housing, so that the drive spindle is locked in relation to the longitudinal axis of the housing without the rotation of the drive spindle being hindered or restricted as a result.
  • the retaining ring is advantageously mounted exactly in the middle between the two right-hand and left-hand threads of the drive spindle, so that the synchronous feed movements the base jaws or clamping jaws self-centering of the workpiece to be clamped, because this is pushed by the respective clamping jaw, which hits the workpiece first, to the opposite clamping jaw until it hits the workpiece to be clamped. Consequently, workpieces of different dimensions can be clamped in a self-centering manner on the clamping devices without having to carry out calibrations or other control measurements.
  • the clamping device according to the invention thus represents a so-called zero-point clamping system.
  • the drive spindle can be moved relative to the longitudinal axis of the housing, because it is mounted on the housing exclusively via the cover sleeves and the respective base jaw. Accordingly, a stop can be provided in alignment with the central axis of the housing, by means of which two clamping sections are formed for the respective clamping jaw arranged opposite thereto. Consequently, each of the two clamping jaws can press a workpiece against the stop. Since the length of the workpiece to be clamped determines the position of the respective clamping jaw in relation to the housing and the drive spindle can be displaced relative to the housing, a workpiece can be clamped between the respective clamping jaw and the stop, the length of which differs from the adjacent clamped workpiece. The position of the jaw which first strikes the longer dimensioned workpiece is set by the workpiece and the drive spindle rotates and the cover sleeve further so that the jaw adjacent thereto can be moved further towards the stop.
  • the clamping device For a further application of the clamping device according to the invention, it is provided to lock one of the base jaws on the housing by means of fastening screws, preferably the base jaw which is arranged furthest away from the crank. Consequently, the locked base jaw serves as a stop for the clamping jaw, which is still mounted in the housing so that it can be displaced relative to the latter, so that a workpiece can be clamped between the two pairs of clamping jaws. The length of the workpiece determines the position of the mobile clamping jaw.
  • the movable clamping jaw can be delivered up to the fixed clamping jaw, since the drive spindle is out of the housing can be unscrewed so that the distance between the fixed and the freely movable clamping jaw can be completely overcome by turning the drive spindle.
  • a clamping device 1 is shown in the form of a vise.
  • the clamping device 1 is intended to hold a workpiece 20 in a position-oriented and self-centered manner in space. This means that the axis of symmetry of the workpiece 20 is aligned coaxially to the central axis 3 formed by a housing 2 of the clamping device 1, specifically this clamping position should be created for all workpieces 20, regardless of their length dimensions.
  • the workpiece 20 fixed by the clamping device 1 is to pass through during the clamping state a machine tool, not shown, can be processed.
  • the vice 1 is therefore fixed in a position-oriented manner on a tool table and in order to achieve repeat accuracy when replacing the workpieces 20, it is necessary for the position of the vice 1 to be maintained in relation to the machine tool and for the workpieces 20 supported on the vice 1 to have an identical spatial position during the clamping state if they have an identical length.
  • the clamping device 1 consists of the housing 2, the cross section of which is U-shaped.
  • the housing 2 thus has two legs 5 and 6 running parallel to one another and a base or web 7 arranged between them.
  • a guide groove 8 is incorporated, which is arranged in a common plane.
  • the cross section of the guide grooves 8 can be U-, dovetail- or T-shaped.
  • a base jaw 11 is inserted, which is movable relative to the housing 2 in this and is mounted in the guide grooves 8 .
  • the clamping jaws 13 can thus be introduced at different positions on the base jaw 11 , as a result of which the span width or the adjustment path ⁇ s of the clamping jaws 13 can initially be adjusted to the geometry of the workpiece 20 .
  • a drive spindle 9 is provided which runs parallel to the two legs 5 and 6 and the web 7 of the housing 2 .
  • One of the free ends of the drive spindle 9 protrudes from the housing 2 so that a crank 18 can be attached to this end of the drive spindle 9 that is freely accessible from the outside in order to rotate the drive spindle 9 .
  • the retaining ring 24 has an axis of symmetry 28 which is aligned with the central axis 3 when the retaining ring 24 is in the mounted state on the drive spindle 9 .
  • the self-centering of the clamping device 1 is achieved by the position of the retaining ring 24 , because the retaining ring 24 is positioned exactly in the middle between the two right-hand and left-hand threads 10 of the drive spindle 9 .
  • two cover sleeves 21 are provided, which are partially slid onto the drive spindle 9 and through which the thread 10 of the drive spindle 9 is completely closed to the outside or watertight/airtight.
  • the cover sleeves 21 In order to fix the retaining ring 24 in the exact position on the drive spindle 9, it is necessary to screw the cover sleeves 21 onto the thread 10 of the drive spindle 9 and when the cover sleeves 21 are manually moved towards one another, until the respective end of the thread 10 is reached, the two opposite cover sleeves 21 hold the retaining ring 24 already pushed onto the drive spindle 9 exactly in the middle between them.
  • the distance between the retaining ring 24 and the two cover sleeves 21 is therefore the same and the retaining ring 24 can be locked on the drive spindle 9 with the aid of fastening screws 19 .
  • a groove 34 is worked into the retaining ring 24 .
  • the axis of symmetry 28 of the retaining ring 24 runs in alignment with the center of the groove 34.
  • each of the cover sleeves 21 has a right-hand and left-hand internal thread 22 which is fully or partially in engagement with the respective right-hand or left-hand thread 10 machined into the drive spindle 9 . It is technically imperative that the right-hand thread 10 of the drive spindle 9 is assigned to a right-hand internal thread 22 of the cover sleeve 21 and the left-hand thread 10 of the drive spindle 9 is assigned to a left-hand internal thread 22 of the cover sleeve 21 .
  • each of the cover sleeves 21 has a right-hand and left-hand external thread 23 which engages with a thread 12 machined on the base jaws 11 .
  • a fixing bracket 14 can be installed on the housing 2 using the fastening screws 19 .
  • the fixing bracket 14 is U-shaped in its cross section. This consists of two parallel legs 31 and 32 and a web 33 arranged between them. The web 33 faces the open side of the housing 2 and the legs 31, 32 protrude into the interior of the housing 2, i.e. run in the area of the two parallel guideways 8.
  • the two legs 31, 32 and the web 33 engage around the retaining ring 24, specifically the legs 31, 32 and the web 33 engage in the groove 34 of the retaining ring 24. Accordingly, the position of the drive spindle 9 is fixed relative to the housing 2 via the retaining ring 24 .
  • the drive spindle 9 can thus only rotate in the housing 2, but does not change its position relative to the housing 2 due to the locking of the fixing bracket 14 with the retaining ring 24.
  • the retaining ring 24 is exactly the same distance from the respective start of the right-hand and left-hand threads 10 of the drive spindle 9 and the position of the drive spindle 9 is fixed with the aid of the positive operative connection between the retaining ring 24 attached to the drive spindle 9 and the fixing block 14,
  • the workpiece 20 is aligned by the synchronous linear movement of the clamping jaws 13 moving towards one another and, on the other hand, the drive spindle 9 cannot be moved in the longitudinal direction 4 of the housing 2i relative to it.
  • the axis of symmetry 28 of the retaining ring runs exactly in alignment with the central axis 3, which means that each clamped workpiece 20 is equipped centrally with respect to the central axis 3.
  • the web 33 protrudes in the middle beyond the surface formed by the housing 2, so that the workpiece 20 can rest on this surface.
  • the two cover sleeves 21 first move via the respective pair of threads 10 and 22 in the direction of the retaining ring 24, since the rotation of the cover sleeve 21 is fixed by the base jaw 11 and consequently that of the torque provided by the drive spindle 9 is converted into a linear movement of the cover sleeve 21 and the base jaw 11 .
  • the fixing block 14 is replaced by a stop 15 fastened to the housing 2 .
  • the stop 15 has a U-shaped contour in cross section.
  • the two legs of the stop 15 running parallel to one another are identified by the reference numerals 36 and 37 and the web arranged between them is identified by the reference numeral 38 .
  • the legs 36, 37 and 38 of the stop 15 are at a distance from the retaining ring 14.
  • the air gap 39 present between the legs 36, 37 and the web 38 of the stop 15 releases the linear movement of the drive spindle 9 or does not fix it.
  • the position of the drive spindle 9 can accordingly be shifted relative to the longitudinal axis 4 of the housing 2 .
  • the stop 15, in particular its web 38 projects into the clamping area of the clamping jaws 13, as a result of which these are divided into two clamping sections.
  • a workpiece 20 of different lengths can be clamped between the stop 15 and the clamping jaw 13 adjacent thereto, since the different lengths of the workpieces 20 can be compensated for by the relative position of the drive spindle.
  • FIG. 10 Another advantageous application of the clamping device 1 according to the invention is in figure 10 shown.
  • the base jaw 11 facing away from the crank 18 is fixed to the housing 2 by means of the fastening screws 19 . Consequently, this base jaw 11 cannot move relatively in the direction of the longitudinal axis 4 of the housing 2 and the clamping jaws 13 fastened to it serve exclusively as a stop.
  • the opposite base jaw 11 can be configured up to the fixed base jaw 11 or clamping jaw 13 since the relative position of the drive spindle relative to the housing 2 can be displaced.
  • the free end of the drive spindle 9 opposite the crank 18 can in fact protrude from the housing 2 or be screwed out on it.
  • the clamping device 1 according to the invention can thus provide three completely different clamping situations without the respective users of the clamping device 1 having to undertake time-consuming and complicated conversion costs.
  • the thread pairings 10 and 22 on the one hand and 23 and 12 on the other hand are permanently closed, so that impurities in the form of chips, hydraulic fluids or the like cannot penetrate these threads.
  • the vise 1 according to the invention can consequently be used for different clamping situations without time-consuming and complicated conversion measures.
  • the drive spindle 9 can namely on the one hand be fixed by the fixing bracket 14 and on the other hand be displaced freely over the central axis 3 along the longitudinal axis 4 of the housing 2 .
  • the two are opposite Front sides of the housing designed open. This means that both the guideways 8 and the drive spindle 9 and the cover sleeves 21 can emerge from the planes formed by the end faces of the housing 2 . Accordingly, the freedom of movement of the drive spindle 9, the base jaws 11 and the cover sleeves 21 through the housing 2 is fully released.
  • spacer rings 16 are installed between the drive spindle 9 and the base jaw 11 or the housing 2, through which the drive spindle 9 can be buffered in the direction of the longitudinal axis 4 and also fixed in this direction as soon as one of the spacer rings 16 is both on the Drive spindle 9 and on the base jaw 11 or the housing 2 reaches the releasable system or engagement.
