Embodiment Construction

[0021] Figure 1 ~ Figure 3 It is a three-sided view of an embodiment of a height-adjustable pad iron for flat-nose pliers. It can be seen from these three figures that the lower surface of the upper slider 2 is a slope with a protrusion, and it is connected with the belt of the lower pad 1. The inclined surface with grooves cooperates and can slide relatively in this guide groove. When the two slide relative to each other for a distance, their total height will also change accordingly. The value of the change function is determined by the sine function of the inclined angle of the inclined surface. , and the upper and lower planes will always remain parallel.

[0022] Figure 4 is the external view of the height-adjustable shim embodiment for the vise, by Figure 4 It can be seen in the figure that the vernier scribe line drawn on the large side of the upper slider 2 and the lower parallel iron 1 can accurately control the relative displacement distance of the upper slider ...

Abstract

The invention belongs to a sizing block (cushion block) in mechanical clamps, and in particular relates to a sizing block with adjustable height for flat tongs; in the invention, an integral sizing block is changed into two sections of slanting sizing blocks which can slide relatively in a guide groove, so as to realize possibility that the height of the sizing block can be fine-tuned accurately. The sizing block can be applied to machinery processing of flat tongs, and clamps, check tools and other mechanical devices; by adopting the special function that the height of the sizing block can be fine-tuned accurately, the processing and manufacturing cost can be remarkably saved.

Description

Technical field: [0001] The invention relates to a pad iron (or pad) belonging to mechanical fixtures, in particular to a height-adjustable pad iron suitable for vise pliers. [0002] The pad iron can be used in machining of vises, and can also be used in jigs, inspection tools and other mechanical devices. Through its unique function of fine-tuning the height accurately, it can significantly save processing and manufacturing costs. Background technique: [0003] The use of flat pliers to clamp parts for mechanical cutting is a widely used clamping method. However, in practical applications, it is often encountered that some smaller parts need to use backing iron to raise the workpiece to a suitable height on the vise, but the height and thickness of the backing iron are always limited and configured, and often cannot be found or used. Several shims are put together to form a suitable height. At this time, we have to customize a suitable shim to meet the needs of use. Cust...
