MATERIAL-SAVING AND ENERGY-SAVING MULTIFUNCTIONAL BENCH CLAMP

摘要

A material-saving and energy-saving multifunctional bench clamp comprises a movable clamp body (1), a fixed clamp body (4) and a transmission pair of screw (11) and nut (10). The fixed clamp body (4) is provided with holding accessories (3) and retractable locating-guiding device (9). The movable clamp body (1) is made up of a left part and a right part. The right part is a cylinder guide rail (1.3) of sleeve form and slidingly matched with an inner opening of the fixed clamp body (4). The left part is provided with two work heads (1.1, 1.2), each head includes holding members (2, 12) which form a pair of holding assembly together with the accessories (3) installed on the fixed clamp body (4). At least two axial locating-guiding key grooves are shaped on a guide rail surface of an outer cylinder of the right part of the movable clamp body(1) and positioned the corresponding work heads of the left part of movable clamp body(1). The bench clamp not only reduces the processing surface and cost, but also saves about 30% material of clamper body under the same standard size and rated clamp force by comparison to the old multifunctional bench clamp.
