Ride-on clamp
Securely fix workpieces
Every workpiece quickly reveals its pitfalls when clamping. If the clamping claw cannot be turned to the clamping point due to the part geometry, things get tricky.
Erwin Halder 's innovative ride-on clamp is a solution that allows users to literally postpone the problem.
"There are many ways to clamp a component precisely and reliably. Sometimes, for example, fixing in a hole or a recess can be useful for machining. Normal sit-on clamps are not suitable for such situations because the clamping claw cannot be swiveled to the right position due to the workpiece. This is why we have developed this new variant: For clamping, the clamp can be moved backwards by up to 30 mm and then moved forwards again once the workpiece has been inserted. The user then sets the desired clamping position using the knurled screw and secures everything with the knurled nut. This ensures that the workpiece is clamped quickly and securely," says Sales Manager Bernd Janner. In order to easily reproduce the clamping point, the clamp can be very simply secured against twisting with the help of a positioning ring.
The sliding ride-on clamps with an M12 diameter are available in two different heights, which can be flexibly increased using height cylinders and washers. For both sizes, users can choose between three different types of actuation: via a clamping screw, an eccentric lever and an adjustable clamping handle with axial bearing. Halder manufactures the ride-on clamps from case-hardened, burnished and ground case-hardening steel and they clamp with 10 kN.
To securely fasten the ride-on clamps to a fixture or machine table, users can fall back on two common fastening options: on the one hand, a nut for T-slots (T-slot nut according to DIN 508) and, on the other, a grub screw that is inserted directly into the plate or fixture. In addition, the compact design of the slide-on clamp - in contrast to clamps - means that it requires significantly less installation space. This enables the use of shorter cutting tools, which in turn results in higher productivity.
