Definitions
- the invention relates to a vice with a basic body, a fixed clamping jaw attached to the basic body and a linearly adjustable guiding mechanism on the basic body, tensioning slide against the clamping jaw, with interchangeable jaw elements on the mutually facing sides of the clamping slide and fixed clamping jaw are arranged with in particular profiled clamping surfaces, between which a workpiece is held.
- Such vices are generally known and are available in practice in most workshops in order to be able to clamp workpieces that are to be machined manually.
- the cocking slide is arranged on a threaded spindle mounted in the base of the vice so that when the threaded spindle rotates, the cocking slide moves in the direction of the fixed clamping jaw or away from it by means of a hand crank, and thus between the clamping slide and clamping jaw positioned workpiece clamped between the clamping surfaces of the jaw elements or a clamped workpiece is released.
- a clamped workpiece can be machined on the surfaces protruding upwards or laterally from the vise. To machine the other sides, it is necessary in each case to release the workpiece from the clamping, reposition it and clamp it again. This is often perceived as complex, in particular if the workpiece is to be processed, for example, with a column drill has to assume a defined position, since the positioning of the workpiece is then only possible using special spacers which are positioned between the workpiece and a support surface of the base body. This type of positioning is often not sufficiently precise and is also very time-consuming.
- the object of the invention is accordingly to provide a vice of the type mentioned, which allows multi-sided machining of a workpiece with little positioning and clamping effort.
- the jaw elements are arranged rotatably about a common axis running parallel to the adjustment direction of the clamping slide on the clamping slide and clamping jaw and are mounted such that a rotary movement of the jaw elements also under the effect of the clamped Workpiece on the jaw elements acting clamping forces is possible, and that at least one of the jaw elements can be determined in several rotational positions by a locking device.
- the jaw element arranged on the clamping jaw is formed on an axial end of a pin, which is rotatably mounted in the clamping jaw by means of an axial bearing, in particular, which absorbs clamping forces, and the jaw element is preferably displaced from the clamping slide by 0. Holds 1 mm to 0.3 mm apart, the jaw element provided on the clamping slide can be mounted in the same way. This enables the jaw elements to be rotated in a simple manner under the action of an axial load.
- the free axial end of the pin facing away from the jaw element is expediently guided out of the jaw and provided with an actuating element for rotating the pin and engages with a locking device for locking the pin bringable.
- a flange is advantageously formed on the free end of the pin protruding from the clamping jaw, which flange has a flat toothing on its surface facing away from the clamping jaw, and is a locking block on the base body with one of the
- the spur gear associated with the spur gear is held in a rotationally fixed manner and guided against the flange and movable back in order to bring the two spur gears into engagement with one another to fix the pin and to detach them again.
- a scale is preferably provided on the outer circumference of the flange for reading the respective rotational position of the jaw element mounted on the clamping jaw and thus of a clamped workpiece.
- the jaw elements can be advantageous to provide the jaw elements with a support web on their lower area facing the base body, on which a workpiece to be machined can be positioned at a distance from the base body for clamping, so that additional positioning aids are not required.
- the upper side of the base body as a support surface, on which spacer elements can be placed for positioning a workpiece, which elements can be removed before the workpiece is rotated, in order to create the space below the workpiece which is necessary for the rotation.
- the positioning and clamping process can also be kept low by the clamping surfaces of the jaw elements being complementary to the outer contour of a workpiece to be clamped.
- the clamping surfaces of the jaw elements can each be formed as recesses in the form of cylindrical sections.
- FIG. 1 is a side view of a vice according to the invention, partially cut,
- Figure 2 shows the vice of Figure 1 in plan view
- FIG. 3 shows the vice shown in Figure 2
- FIGS. 1 to 3 An embodiment of a vice according to the present invention is shown schematically in FIGS. 1 to 3.
- the vice includes a base body 1, in which a threaded spindle 19 is rotatably mounted, which at its one axial end, the operating end, is a hexagonal Head-shaped coupling element 21, on which a hand crank can be plugged in order to rotate the threaded spindle 19.
- the threaded spindle 19 has an outer thread 20 on its outer circumference, onto which a tensioning slide 2 is screwed.
- the cocking slide 2 protrudes upward out of the base body 1 and, as is shown in particular in FIG. 3, lies on the top of the base body 1 and is guided on the base body 1 so as to be adjustable in the axial direction of the threaded spindle 19 and secured against rotation.
- a fixed clamping jaw 3 is further provided on the base body 1, which is screwed onto the top of the base body 1.
- the fixed clamping jaw 3 and the clamping slide 2 interact in a known manner for clamping a workpiece and each have interchangeable jaw elements 4, 5 on their mutually facing sides.
- the jaw elements 4, 5 are arranged on the clamping jaw 3 or the clamping slide 2 so as to be rotatable about a common axis X running parallel to the axial direction of the threaded spindle 19, in such a way that a rotational movement of the jaw elements 4, 5 also under the action the axial clamping forces acting on the jaw elements 4, 5 when the workpiece is clamped is possible.
- coaxially aligned pins 8, 14 are rotatably supported by axial bearings 15, 16, which support the jaw elements 4, 5 at their mutually facing axial ends and each by preferably 0.1 mm to Hold 0.3 mm apart from the clamping slide 2 or the clamping jaw 3 in order to keep the frictional forces low.
- the pin 8 mounted in the fixed jaw 3 protrudes with its free axial end pointing away from the jaw element 5 out of the jaw 3 and is designed as a flange 10 which carries on its outer circumference an operating lever 9 through which the pin 8 and thus that Cheek element 5 can be rotated manually.
- a locking device is provided in order to lock the pin 8 with the jaw element 5 in different rotational positions.
- a locking block 13 is provided, which rests on the upper side of the base body 1 and is guided on the base body 1 by guide rails 18 in the axial direction of the threaded spindle 19 to the flange 10 and away from it and is held in a rotationally fixed manner.
- the locking block 13 carries on its side facing the flange 10 a spline 12, which can be brought into engagement with a spline 11 provided on the flange 10 by an adjustment movement of the locking block 13 against the flange element 5 in the respective rotational position in which it is located to arrest.
- a scaling (not shown) is provided on the outer circumference of the flange 10 in order to be able to read off the respective rotational position of the jaw element and thus of a clamped workpiece.
- the grid by which the jaw element 5 mounted on the clamping jaw 3 and thus the workpiece can be adjusted is determined by the division of the plan gears 11, 12 which cooperate with one another to fix the jaw element 5.
- the pin 14 mounted in the cocking slide 2 cannot be ascertained in the embodiment shown, but it is possible to also create a locking device for this pin 14.
- a Slider 2 arranged and can be brought into engagement with the pin 14 clamping or clamping ring.
- a recess 17 is provided in the upper side of the base body 1 in order to create the space necessary for the rotation of the jaw elements 4, 5 or of a workpiece clamped between the jaw elements 4, 5.
- the locking block 13 is first moved against the flange 10 in order to bring the face teeth 11, 12 into engagement with one another and thus to hold the jaw element 5 in the clamping jaw 3 in a rotationally fixed manner.
- a workpiece is positioned between the clamping slide 2 and the clamping jaw 3 and the clamping slide 2 is moved in the direction of the clamping jaw 3 by rotating the threaded spindle 19 until the workpiece is clamped between the jaw elements 4, 5 and the workpiece can be machined .
- the locking block 13 is moved away from the flange 10, so that the toothed teeth 11, 12 provided on the locking block 13 and flange 10 disengage and the pin 8 with the jaw element 5 be ⁇ clamped workpiece can be rotated, the jaw element 4 mounted in the clamping slide 2 running freely.
- the locking block 13 is again moved in the direction of the clamping jaw 3 until the face toothing 12 formed on the locking body 13 has the teeth provided on the flange hen face gear 11 comes into engagement and the jaw element 5 mounted on the clamping jaw 3 is locked in a rotational test.
