Liftable cushion block

Abstract

The invention discloses a liftable cushion block. The liftable cushion block comprises an upper cushion plate, a sliding groove fixedly connected onto the bottom surface of the upper cushion plate, a groove-type base, a double-thread screw which is parallel to the bottom surface of the groove-type base and penetrates through the two vertical side surfaces of the groove-type base and a first sliding block and a second sliding block which are separately arranged on the forward and reverse thread sections of the double-thread screw through thread pairs, wherein the lower end of a first connection rod is hinged to the first sliding block, and the upper end of the first connection rod is slidably connected into the sliding groove; the upper end of a second connection rod is hinged to the upper cushion plate, and the lower end of the second connection rod is hinged to the second sliding block; and the first connection rod is hinged to the second connection rod at linking holes. Specifically, multiple linking holes can be formed in the first connection rod or / and the second connection rod, and the second connection rod comprises two sub connection rods which are parallelly arranged on two sides of the first connection rod. The liftable cushion block has the beneficial effects that defects in the prior art are solved; the defect that the height of an ordinary cushion iron block cannot be adjusted is overcome through height-direction adjustment; the use range is enlarged; and by using the liftable cushion block, required slopes can be machined.

Description

Technical field [0001] The invention relates to a cushion block of mechanical clamps, in particular to a cushion block with adjustable height which can be used in flat-nose pliers or machine tools. Background technique [0002] In mechanical cutting, using flat-nose pliers to clamp parts is a very common clamping method. However, in practical applications, it is often encountered that some parts do not have suitable horns to raise the workpiece on the flat-nose pliers to the required height. At this time, only self-made horns can be used. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a liftable cushion block that is not only adjustable in height but also capable of bevel processing. [0004] The technical solution adopted by the present invention to solve its technical problems is: a liftable cushion block with an upper backing plate, a sliding groove fixedly connected to the bottom surface of the upper backing plate, a ...
