Definitions
- the invention relates to a clamping device according to the preamble of patent claim 1.
- the object of the invention is to provide a clamping device of the type mentioned, which allows an increased clamping force.
- the side jaws are floatingly mounted on the jaws.
- the workpiece can first be clamped firmly between the two clamping jaws and then between the side clamping jaws. If the increase of the clamping force does not have the highest priority, one of the two side jaws against the jaw can be fixed and used as a stop.
- the side jaws may be slidably guided over a guide lug in a guide groove of the clamping jaws.
- the guide groove in the clamping jaws e.g. a T-shaped cross-section and the guide lug on the side jaws contain a matched to the shape of the guide groove T-shaped outer contour.
- the guide lugs of the side jaws may be arranged to the guide groove in the jaws facing compression springs. This allows the side jaws spring biased held in the guide and falling out of the side jaws are avoided.
- the clamping device may be designed as a centric clamping device, in which the two clamping jaws are at the same time together or can be moved apart by the adjusting mechanism.
- the two clamping jaws can be adjusted via slides displaceably guided in the base body. The slides can be installed in the body so that there is a protected against dirt and insensitive to chips construction.
- one of the two clamping jaws can also be designed as a fixed jaw.
- the jaws may be formed as replacement jaws and releasably secured to an associated jaw main body. As a result, the jaws can be replaced if necessary and adapted to the respective clamping task. But the jaws can also be integrated in a base jaw or a clamping jaw body. Both the jaws and the side jaws may have teeth on their clamping surfaces to improve the grip effect. The jaws and the Side jaws can also be ground and / or coated with a layer of hard material.
- clamping device includes a base body 1, on which two clamping jaws 2 and 3 slidably guided via slides 4 and 5 and are adjustable in opposite directions by an adjusting mechanism 6 with an adjusting spindle 7.
- the adjusting spindle 7 for opposite movement of the two slides 4 and 5, the adjusting spindle 7 in a conventional manner, two running as right or left thread external thread for engagement with corresponding internal threads at through holes of the two slides 4 and 5 have.
- the clamping jaws 2 and 3 are formed as replacement jaws and releasably secured to a mounted on the respective slide 4 and 5 jaw main body 8 and 9.
- clamping jaws 2 and 3 can also be integrated on the clamping jaw main body 8 and 9.
- the main body 1 has two spaced side cheeks 10 and 11 with upper guide surfaces 12.
- the two guide surfaces 12 are executed on a hardened and ground upper part of the two side cheeks 10 and 11 of the main body 1.
- the guide surfaces 12 can also be arranged on separate and replaceable if necessary guide rails or guide rails.
- the slides 4 and 5 are fitted and guided displaceably.
- the slides 4 and 5 have a stepped cross-section with an upper bearing surface 13.
- the clamping jaw main body 7 and 8 are fastened by screws 14.
- the clamping device is designed as a centric clamping device, in which the two clamping jaws 2 and 3 together with the respective clamping jaw main body 7 or 8 by rotation of the adjusting spindle 6 either simultaneously or can be moved together.
- a contour 15 designed, for example, as an external hexagon, is provided for engaging a hand crank or another actuating element on its end projecting outwards relative to the slide 4.
- each two adjustable side jaws 16 and 17 or 18 and 19 are arranged on the two mutually facing side surfaces of the two clamping jaws 2 and 3 respectively.
- the side jaws 16 and 17 or 18 and 19 are guided displaceably in the clamping jaws 2 and 3 perpendicular to the adjustment of the clamping jaws 2 and 3 and can be adjusted by a here designed as an adjusting spindle actuator 20 and 21 respectively.
- a workpiece 22 can be tensioned not only between the two clamping jaws 2 and 3 but also laterally between the side clamping jaws 16 to 19.
- the total clamping force can be increased.
- the side jaws 16 and 17 or 18 and 19 are floatingly mounted on the clamping jaws 2 and 3.
- the workpiece 22 can first be tensioned between the two clamping jaws 2 and 3.
- the side jaws 16 and 17 or 18 and 19 can be pressed uniformly by appropriate actuation of the actuators 20 and 21 to the sides of the workpiece 22, whereby the workpiece 22 can be tightened from four sides process reliability and high clamping forces. If the increase in the clamping force is not the top priority, one of the two side jaws 16 and 17 or 18 and opposite the jaw 2 and 3 can be fixed and used as a stop.
- FIGS. 5 to 7 is the jaw 2 with the two side jaws 16 and 17 shown in different views.
- a guide groove 23 for the displaceable guidance of the two side clamping jaws 16 and 17 is provided in the clamping jaw 2.
- the running in the longitudinal direction of the clamping jaw 2 guide 23 has in the embodiment shown on a T-shaped cross-section.
- the side jaws 16 and 17 include an engaging in the guide groove 23, lateral guide lug 24 with a matched to the shape of the guide groove 23, T-shaped outer contour.
- the two side jaws 16 and 17 are guided in the guide groove 23 slidably.
- FIG. 7 It can be seen that in the guide lugs 24 to the guide groove 23 facing compression springs 25 are arranged. By arranged in corresponding countersunk springs compression springs 25, the side jaws 16 and 17 are held under a bias in the guide groove 23. As a result, falling out of the side clamping jaws 16 and 17 from the guide groove 23 can be avoided.
- the setting device designed as an adjusting spindle has an annular collar 26, a cylindrical guide region 27 for a through-bore 28 in the side clamping jaw 16 and a threaded region 30 engaging in an internal thread of a threaded bore 29 of the side clamping jaw 17.
- Both the clamping jaws 2 and 3 and the side clamping jaws 16 and 17 or 18 and 19 have at their clamping surfaces a toothing 34 and 35, respectively.
- the clamping jaws 2 and 3 and the side clamping jaws 16 and 17 or 18 may also be ground or coated with a hard material layer.
