Hand Tool Toggle Clamp Handle Clamp

The Hand Tool Toggle Clamp Handle Clamp hold-down clamp is a handle toggle clamp of hand tool types.

Hand Tool Toggle Clamp Handle Clamp Advantages

By using the toggle link principle Hand Tool Toggle Clamp Handle Clamp toggle clamps offer decisive advantages:

The clamping arm retracts to such an extent that the workpiece can be loaded and unloaded completely unobstructed.
Even the slightest forward movement of the operating handle brings the clamping arm with the contact pad over the workpiece.

The clamping force Fs exerted on the workpiece is mainly dependent on the following criteria:

– the input force which is applied to the operating handle,

– the position of the clamping bolt on the clamping lever.

Since the applied force on the lever by the operator is not known, the clamping force Fs shown in the table is only specified for pneumatically operated clamps.

The clamping force Fs can be altered by re-adjusting the position of the clamping bolt. The clamping force increases if the entire contact area of the bolt arrives on the workpiece prior to the toggle linkage reaching the dead center point. This effect is illustrated clearly when using an elastic clamping pad.

In this position, the toggle linkage has arrived in the over-center lock position and the operating lever has reached a firm stop and is thus prevented from opening until it is released by the operator.

The force which the clamp is capable of withstanding in this over-center lock position without suffering permanent deformation is known as holding force FH. The holding force has a characteristic value (co-efficient) for toggle clamps and this value is mainly dependent on:

– the size (dimensions, geometry) of the toggle clamp,

– the position of the clamping bolt on the clamping arm

Besides the Hand Tool Toggle Clamp Handle Clamp, we also have the Horizontal Acting Toggle Clamps, Latch Acting Type Toggle Clamps, Push-pull Type Toggle Clamps, Quick-release Toggle Clamps, etc.
