Self-locking type eccentric wheel manual pressing device

Abstract

The invention discloses a self-locking type eccentric wheel manual pressing device. The self-locking type eccentric wheel manual pressing device comprises a T-shaped pressing head, a fixing supporting base and a driving rod and further comprises an eccentric wheel and a reset spring, wherein the T-shaped pressing head is used for pressing a workpiece; the fixing supporting base is used for installing the eccentric wheel; the driving rod is used for driving the eccentric wheel to press the T-shaped pressing head; the eccentric wheel is used for driving the T-shaped pressing head to press the workpiece; the reset spring is used for driving the T-shaped pressing head to reset upwards. The lower end of the driving rod is fixedly installed on the eccentric wheel. An anti-skid handle is fixedly installed at the upper end of the driving rod. The eccentric wheel is rotationally installed on the fixing supporting base. The T-shaped pressing head is arranged on the lower side of the eccentric wheel. The reset spring is arranged on the lower side of the T-shaped pressing head. The self-locking type eccentric wheel manual pressing device has the following characteristics that pressing is conducted through the eccentric wheel, the pressing force is large, the self-locking performance is good, operation is convenient, the design is reasonable, the structure is simple and compact, the universality is high and the application scope is wide.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a fixture, in particular to an eccentric wheel self-locking manual pressing device. Background technique [0002] When machining parts, the workpiece to be processed must first be positioned and pressed. At present, the commonly used way to tighten the workpiece is to use nuts and bolts to fix it. Although this method is simple and convenient, the operator has the following problems when using it. Disadvantages: It takes a long time to press the workpiece, the production efficiency is low, the tightening process is laborious, the labor intensity is high, and the degree of automation is low, which makes the enterprise at a disadvantage in the competition in the same industry. Among the common clamping mechanisms, the eccentric cam clamping mechanism not only has the function of self-locking, but also has the function of amplifying the force, and has the advantages of s...
