Abstract

The utility model relates to a shim plate (cushion block) belonging to mechanical fixtures, in particular to the shim plate with adjustable height, which is suitable for a pair of flat tongs. The shim plate consists of a lower shim plate, an upper slide block and fastening screws, and is basically and technically characterized in that a traditional integral shim plate is changed into an inclined shim plate of which the upper section and the lower section can slide and move relatively in a guide slot, and accurate fine tuning of the height of the shim plate can be realized through relative and accurate movement of the upper slide block in the guide slot of the lower shim plate; the lower surface of the upper slide block is an inclined surface with projecting keys and is matched with an inclined surface with a groove of the lower shim plate so as to slide relatively in the guide slot, after the two inclined surfaces slide relatively for a certain distance, the total height of the two inclined surfaces after overlap also changes, a variation function value is determined by a sine function of an oblique angle of the inclined surface, and an upper plane and a lower plane of an assembly always keep parallel.

Description

The parallels of adjustment height

Technical field:

The present invention is a kind of parallels (or claiming cushion block) that belongs to the mechanical clamp class, is meant a kind of parallels that is applicable to the adjustment height that flat-nose pliers uses especially.

This parallels removes and can be applied in the flat-nose pliers machining, also can be used in anchor clamps, cubing and other mechanical device, through its distinctive function that can accurately finely tune height, can save the processing and fabricating expense significantly.

Background technology:

Adopting the flat-nose pliers clamping parts to carry out machine cut processing, is a kind of installation way of extensive application.But in practical application; Running into some less parts through regular meeting need adopt parallels that workpiece bed hedgehopping on flat-nose pliers is arrived suitable height; And the limited configuration always of the height of parallels and thickness; Often can not find or utilize several parallels to piece together suitable height, at this moment have to customize suitable parallels especially and satisfy the use needs.If the workpiece quantity of processing is few, just the customization parallels can be very uneconomical.But in addition, there is not any good solution yet.

Though on flat-nose pliers, adopting parallels that workpiece processing is installed is a kind of mode of widespread usage, not seeing so far to have has any improved invention or report to this type of parallels.

Another patent " fine adjustment vertical platform " the inventor; Number of patent application: in 200910049619.0; A kind of two ramp sections move relative to sliding of utilizing were proposed, can be in they relatively move, according to relatively moving of the angle generation vertical direction at oblique angle; Realized the adjustment purpose of fine tune vertical height; The present invention has quoted this mentality of designing, with integral sizing block change into two sections can be in gathering sill the skewback parallels of slippage relatively, realize that the accurate fine setting of parallels height maybe.

Summary of the invention:

In recent years along with the develop rapidly of modern manufacturing industry and material industry; Machine components trend towards gently day by day, thin, little and multi-functional labyrinthization; When the workpiece of Bao Erxiao is adopted the flat-nose pliers clamping, because the part flat, thin that can supply clamp and narrow, the more requirement of harshness has been proposed naturally for the height and the thickness of parallels; Always along handing down, the monoblock type parallel block that remains unchanged for a long period of time can't satisfy the needs of technical development day by day now.

The invention provides a kind of parallels of adjustment height of new structure, can adjust, realize the precise displacement adjustment of vertical direction, can satisfy modern manufacturing industry can be adjusted height at random to parallels needs through simple laterally moving.

The technical solution adopted for the present invention to solve the technical problems is:

The present invention is by lower padding iron; Top shoe and trip bolt are formed; Its basic fundamental characteristics are: with the parallels of traditional integral formula change into two sections can be in gathering sill the skewback parallels of slippage relatively; Through top shoe in the lower padding iron guide chute relative to accurately moving, realize that the accurate fine setting of parallels height maybe.

Lower surface at top shoe; Be an inclined-plane that has prominent key, it matches with the inclined-plane that has groove of lower cushion block, can in this gathering sill, slide relatively; After distance of the relative slippage of top shoe with lower cushion block; Total height after they are superimposed can change thereupon, and it changes the oblique angle SIN function decision of functional value by the inclined-plane, and also keeping parallelism state always of the last lower plane of this sub-assembly.

The relative displacement distance of top shoe to lower padding iron can accurately be observed, controlled to the vernier groove of on big plane, the same side of top shoe and lower padding iron, portraying, thereby obtain the accurate adjusted height dimension of parallels sub-assembly.

Two screws that connect top shoe and lower padding iron can highly after the end, carry out the positive lock of parallels sub-assembly in adjustment, and the long oval groove of in lower padding iron, offering can satisfy the fixedly requirement of screw behind the relative slide displacement of top shoe.

In practical application, lower padding iron can be made a plurality of of differing heights as required, and top shoe also can be made the plane as required and locate a plurality of of different shoulder heights and thickness, to satisfy the clamping requirement of different parts to be processed.Through the exchange combination of different size, can just can match out multiple construction size with quite few underlay and top shoe, satisfy the clamping needs of most of part.

The base altitude of lower padding iron and top shoe and width depend on supporting application flat-nose pliers sized and with the clamping requirement of processing parts.

The invention has the beneficial effects as follows:

The present invention not only can solve the deficiency that common parallels can not be adjusted height, and can realize more carrying out highly micro-function of regulating in vertical direction through realizing the special design of accurate fine adjustment function.

The present invention is a general mechanical fitting, except being used in the flat-nose pliers, outside the clamping that satisfies workpiece requires, also can be widely used in the motorisation unit and experimental system of various industries.
