Definitions

  • the invention relates to a vice, in particular a machine vice, with two relatively movable jaws and a drive element, which acts via a drive member on one of the jaws to move them to clamp or release a workpiece on the sliding surface of a support.
  • the drive member is designed such that it biases the driven jaw in the clamping movement against the sliding surface of the support.
  • the jaw moves into the clamping position, it is thus pressed against the sliding surface of the support, so that the jaw does not rise slightly as with the usual vices. This ensures secure and precise clamping of the workpiece.
  • the drive member is a lever mounted in the support and coupled to the jaw, the lever being practically perpendicular to the sliding surface in the idle state.
  • a point on the lever which is at the same height as the sliding surface at rest, describes a circle tangent to the sliding surface when the lever rotates. Because of this circular movement, the more the jaw is moved by the lever, the more it is pressed against the sliding surface, so that play between the jaw and the sliding surface is reliably avoided.
  • the lever In the idle state, the lever can have a neutral position, from which it biases the driven jaw against the sliding surface of the support when moving in one direction or the other. Such a neutral position exists when the lever is practically perpendicular to the sliding surface in the idle state.
  • This fact can be used to use the vice for both external and internal clamping.
  • the vice jaws In the case of internal clamping, the vice jaws, which are optionally provided with attachments, are moved apart so that the attachments can, for example, grip a ring from the inside.
  • the lever is a double-armed lever. This makes it possible to utilize the space in the support in order to achieve a suitable lever translation and to use the elasticity of the lever for tensioning. If an angle lever is used, there is a particularly advantageous construction which makes good use of the available space. It is thus possible to provide a curve between the drive element and the drive element, that is to say the angle lever, in order to transmit the drive force from the drive element to the drive element. This enables a further power transmission, so that a relatively low driving force is sufficient to generate a sufficient clamping force.
  • the curve and / or the drive element are expediently designed such that self-locking occurs.
  • the elastic Ver ensure - shaping of the drive member, eg the angle lever, for maintaining the clamping force of the clamp.
  • the curve is formed by two slides arranged on one side of the drive member and running on rollers in the support, which have a cam slot inclined at an acute angle to the direction of movement, into which rollers arranged on the drive member engage.
  • This self-locking can be increased if sliders and sliding pins are used instead of rollers.
  • the drive element for example the pneumatic cylinder
  • the drive element for example the pneumatic cylinder
  • the vice for example the compressed air source
  • two selectively operable locking members are provided to limit the path of the curve. Depending on whether the vice is used for internal or A ussen- voltage, one of the locking members is actuated.
  • the lever can be coupled to the jaw via a pivot pin.
  • the coupling of the lever with the jaw via a ball joint is more advantageous. This enables the jaw to adapt to a non-parallel workpiece. You can then not only perform a back and forth movement, but also a rotary movement around an axis perpendicular to the sliding surface of the support. However, if it is desired that no such rotation take place or that the rotation be limited, means for limiting or preventing rotation of the jaw on the sliding surface or the support can be provided, e.g. Set screws.
  • the support is advantageously filled with oil, so that the drive element and its bearings as well as the slides run continuously in the oil bath. It is then expedient to provide at least one groove in the slide surface of the support and / or the support surface, in which a seal is located. This seal prevents oil from escaping between the sliding surface and the jaw.
  • a pneumatic cylinder advantageously serves as the drive element.
  • other drive elements would also be possible, for example an electromagnet or an electric motor.
  • a pneumatic cylinder forms a particularly simple drive element.
  • the piston rod also has the advantage that it acts as an oil pump to press oil from the support into the jaw and to lubricate the sliding surface.
  • a control slide valve having at least two positions can be provided, which controls the action on the pneumatic cylinder in such a way that the jaws are moved apart in one slide position and moved against one another in the other position.
  • the control slide can also have a third position in which the pneumatic cylinder can be actuated by a four-way valve.
  • the jaws can be provided both on the front and on the top with peg holes arranged in a grid dimension with a cylindrical fitting diameter and a thread underneath, such that top jaws, which are fixed on the front and top, or special jaws related to the workpiece by means of fitting screws or hollow fitting bushes and through these Inserted clamping screws can be fastened.
  • This enables a particularly universal and efficient use of the vice.
  • the support it is also possible for the support to be provided on the underside with fitting bores arranged in a grid dimension, by means of which the vice can be pinned and screwed onto a base plate, a mounting bracket or the like.
  • the vise consists essentially of the support 1 on the sliding surface 3, the two vise jaws 5 and 6 are movable back and forth.
  • the movable jaw 5 is actuated by a drive mechanism 13, e.g. a pneumatic cylinder. It only covers a short distance, but this is sufficient to clamp the workpiece 15 or to release it again.
  • a drive mechanism 13 e.g. a pneumatic cylinder. It only covers a short distance, but this is sufficient to clamp the workpiece 15 or to release it again.
  • top jaws 19 and 21 are provided for clamping the workpiece 15 on the jaws 5 and 6 and fastened with screws 17.
  • top jaws 19 and 21 shown in FIG. 1 serve to grasp the workpiece 15 on the periphery, that is to say to clamp it from the outside
  • the top jaws 19 'and 21' from FIG. 2 serve to clamp a workpiece 15 'from the inside.
  • the support 1 consists essentially of the trough-shaped base body 23, the interior 24 of which is laterally closed by the support plate 25 and the top by the guide plate 27, or of a box-shaped base body 23, whose interior 24 is laterally closed by the support plate 25.
  • the stability of the base body is significantly increased.
  • the jaw 6 can be moved on the support 1 by means of a hand crank 9 via the spindle 7.
  • the spindle 7 is supported by a double-acting ball socket package 29 with the pressure plate 31, which is screwed to the jaw 6.
  • the spindle is protected by the U-shaped mudguard 33.
  • the clamping curves 11 are rotated (FIGS. 1 and 6).
  • the pull-down wedges 35 which are mounted in the grip bars 37, are shifted inwards, because there is a pin 34 in the cam slot 36 of the clamping curve 11. This causes the jaw 6 to be pressed firmly against the sliding surface 3 and in this position is blocked.
  • lever 41 it is more expedient, as shown, to provide a two-armed lever, in particular an angle lever, which has the arms 45 and 46.
  • the long lever arm 46 is much longer than the arm 45 in the embodiment shown, so that a corresponding translation is achieved.
  • a curve is provided between the drive member, i.e. the pneumatic cylinder 13, and the drive member, i.e. the angle lever 41.
  • This curve is in the form of two slides 47 arranged symmetrically to the lever arm 46, which are connected at one end by the coupling piece 49 to one another and to the piston rod 51 of the pneumatic cylinder 13.
  • the slides 47 have a U-shaped cross section and run on the rollers 53, which in turn are mounted on the axes 55.
  • Each slide 47 has a cam slot 57, which runs at an acute angle to the direction of movement, in which a roller 59 can run, which can rotate on a pin 61 arranged in the angle lever 41.
  • FIG. 4 shows, two locking members in the form of pins 63, 64 are provided, through which the path of the slide 47 can be limited.
  • the locking member 64 is in the locked position, so that only a movement of the jaw 5 for external clamping (Fig. 1) is possible by the drive member 13.
  • Fig. 2 For internal clamping (Fig. 2), the locking member 63 in the Brought locking position and pulled out the locking member 64.
  • the interior 24 of the support is filled with oil.
  • the support surface of the jaw 5 is in the sliding surface of the support or, as shown in FIG. 3.
  • two grooves 65 are provided, in which the seal 66 is located.
  • the ball joint 43 is also lubricated.
  • a cover 69 is screwed to the jaw 5 with screws 70 and thus covers the ball joint 43.
  • a ball joint 43 enables the jaw 5 not only to perform a back and forth movement on the sliding surface 3, but also a rotary movement about an axis perpendicular to the sliding surface of the support.
  • the jaw 5 can e.g. adapt to a non-parallel workpiece. If, however, it is desired that no such rotation takes place or the rotation is limited, the set screws 71 can be actuated (FIGS. 1 and 6).
  • a compressed air connection 73 is provided on the support plate 25. Another hole for a second compressed air connection is closed by a plug 75.
  • two compressed air channels (not shown in the drawing) lead to the control block 77 (FIG. 4), which has a control slide 81 which can be rotated by an adjusting lever 79.
  • compressed air is fed from the connection 73 via the channels 83, 85 into the cylinder 13, which then causes a closing movement to the outside tension.
  • the other side of the piston 14 is steamed up in order to bring the jaw 5 back into the original position.
  • the piston 14 is acted on in the reverse order
  • the control slide 81 is designed such that when it is brought into a neutral intermediate position, it enables remote control via a four-way valve.
  • the sealing plug 75 (FIG. 1) is replaced by a second pneumatic connection.
  • both sides of the piston 14 are then optionally acted upon by compressed air via the pneumatic exclusions.
  • the vice has 1 centering holes 87 in the base of the support.
  • Four centering bores 87 are expediently distributed over the base area in a grid dimension. This makes it possible to accurately and reproducibly insert and screw the vice onto substructure elements if corresponding bores are also provided there.
  • This means that the vice can be used in a modular system.
  • special slot nuts are used, which establish the connection between the centering bushes 87 and the T-slots.
