Abstract
The utility model discloses a lever pipe wrench, pertaining to the clamping apparatus of a pipe wrench; wherein, a pin shaft is arranged on a wrench sleeve; a pin hole actively matched with the pin shaft is arranged on the axial line of the length direction of the lever wrench and two wrench mouths with angle separated by the axial line are arranged on the lever wrench. The utility model has the advantages that the main body is simple in structure, reasonable in force distribution, large in clamping force; the pipe does not deform; the utility model is convenient and flexible to use, and does not slip; dismantling and assembling efficiency is high, so the utility model can be widely used for the clamping and rotating various kinds of pipes and pipe accessories and cylindrical work pieces.
Description
The utility model relates to a kind of clamping device of pipe vice.
When existing pipe vice is screwed to adjusting nut, come the clamping pipe by suppressing strength, pipe is yielding, is difficult for clamping, easily skids, and often needs during operation to repeat could clamp many times, and work efficiency is low.
The utility model purpose provides a kind of lever pipe vice, and it is simple in structure, and is easy to operate, and clamping force is big, and is non-slip, and pipe is indeformable, and the work efficiency height.
The purpose of this utility model is achieved in that referring to accompanying drawing 1 sequence number 1 is the pincers cover among Fig. 1, and sequence number 2 is an adjusting nut, and sequence number 3 is an adjustable clamp, and sequence number 4 is a bearing pin, and sequence number 5 is a flat spring, and sequence number 6 is a rivet, and sequence number 7 is lever tongs.Put at pincers and to establish a bearing pin, on lever tongs axis along its length, establish a pin-and-hole and bearing pin movingly, and be provided with two jaws that have angle that divide according to axis at lever tongs, along its length on the line of axis, also be provided with two jaws that have angle that divide according to the connecting shaft line at adjustable clamp and lever tongs.When tightening pipe, handgrip is moved towards tight direction, and d point on the lever jaw and 3 of a, b on the moving jaw compress pipe simultaneously at this moment, when the dismounting pipe, handgrip is moved towards the direction of pine, and this moment, 3 of a, b on point of the c on the lever jaw and moving jaw compressed pipe simultaneously.Because lever principle, the power of moving is big more, and clamping force will become the increase of multiple.
Because adopt such scheme, entire body is simple in structure, stressed distribution is reasonable, and chucking power is big, and pipe is indeformable, install and remove flexible, non-slip, the work efficiency height.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is total figure of this lever formula pipe vice.
Fig. 2 is the nip part component.
Fig. 3 is N-N and K-K profile.
Adjustable clamp of the present utility model and lever tongs can adopt the spheroidal graphite cast-iron material, after heat treatment can obtain higher intensity, Hardness, wearability and impact flexibility etc. can reduce castings sectional, weight reduction. Machined rear fitted position essence Really, cooperate intermittence little, do not wave and rock, blackening process can be carried out in the surface.
