Embodiment Construction
[0010] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0011] Such as figure 1 A liftable block shown has a grooved base 4, an upper backing plate 1, a sliding groove 2 fixed on the bottom surface of the upper backing plate 1, parallel to the bottom surface of the grooved base 4 and running through the grooved base 4. The double-ended screw rod 9 on the side of the double-ended screw rod 9 is respectively provided with the first slider 5 and the second slider 8 on the positive and negative thread sections of the double-ended screw rod 9 through the thread pair, and the lower end of the first connecting rod 7 is hinged on the first slider 5. The upper end is slidingly connected ...

The invention discloses a lifting bearer supporting bracket. The lifting bearer supporting bracket comprises an upper supporting plate, a sliding trough, a trough-shaped base, a double-head threaded rod, a first slide block and a second slide block, wherein the sliding trough is fixedly connected to the bottom surface of the upper supporting plate, the double-head threaded rod is parallel to the bottom surface of the trough-shaped base and penetrates through the two vertical type side surfaces of the trough-shaped base, and the first slide block and the second slide block are arranged on a right-hand thread section and a left-hand thread section of the double-head threaded rod correspondingly through thread pairs; the lower end of a first connecting rod is hinged to the first slide block, the upper end of the first connecting rod is slidably connected to the interior of the sliding trough, the upper end of a second connecting rod is hinged to the upper supporting plate, and the lower end of the second connecting rod is hinged to the second slide block; and the first connecting rod and the second connecting rod are hinged to connecting holes, specifically, multiple connecting holes can be machined on the first connecting rod or / and the second connecting rod, and the second connecting rod comprises two connecting rod bodies which are parallelly arranged at the two sides of the first connecting rod correspondingly. The lifting bearer supporting bracket has the beneficial effects that the defects exist in a background technology are overcome, the defect that the height of common cushion iron cannot be adjusted is overcome through adjustment in the height direction, and the application range is widened; and a needed oblique plane can be machined by using the lifting bearer supporting bracket.
Description
technical field [0001] The invention relates to a cushion block of mechanical fixtures, in particular to a height-adjustable cushion block which can be used in flat-nose pliers or machine tools. Background technique [0002] In mechanical cutting, it is a very common way to clamp parts with flat nose pliers. However, in practical applications, it is often encountered that some parts do not have suitable shims to raise the workpiece on the vise to the required height. At this time, only self-made shims can be used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liftable cushion block which is not only adjustable in height but also capable of processing inclined planes. [0004] The technical solution adopted by the present invention to solve the technical problem is: a liftable cushion block, which has an upper backing plate, a sliding groove fixed on the bottom surface of the upper backing plate, a groove bas...
