Abstract

The invention provides a pressing surface structure of pressing tongs. According to the pressing surface structure, when an action mechanism slightly shakes, the pressing surface of the lower pressing end still presses a datum plane without exceeding the range of the datum plane, and thus the pressing stability and accuracy of the pressing tongs are ensured. The pressing surface structure comprises a connecting end and a pressing end, wherein the connecting end is connected with the pressing end. The pressing surface structure is characterized in that an edge angle of the pressing surface of the pressing end is chamfered; and the chamfer is formed in a way that a slope is processed at the edge position of the chamfer.

Description

The following pressure surface structure of pressing tongs

Technical field

The present invention relates to the technical field of auto parts and components cubing structure, be specially the following pressure surface structure of pressing tongs.

Background technology

Cubing need be used pressing tongs in the auto parts and components, and existing pressing tongs generally comprises link, presses down end two parts, the external actuating mechanism of link; Its following pressure surface that presses down end corresponding datum level of fitting fully, its both shape, consistent size, thus make that the compression area of datum level is enough big; Guarantee pressing down firmly, stablizing of pressing tongs; But when pressing tongs after through action repeatedly, its actuating mechanism is prone to generation slightly rocks, thereby makes down the pressure surface corresponding datum level of no longer can the outer ring fitting; Make that pressure surface is prone to be pressed onto the place beyond the datum level under the pressing tongs, that has reduced pressing tongs presses down stability, accuracy.

Summary of the invention

To the problems referred to above, the invention provides the following pressure surface structure of pressing tongs, it makes that the following pressure surface that presses down end still was pressed onto datum level, can not exceed the scope of datum level when actuating mechanism took place slightly to rock, that has guaranteed pressing tongs presses down stability, accuracy.

The following pressure surface structure of pressing tongs, its technical scheme is such: it comprises link, presses down end, and said link connects the said end that presses down, and it is characterized in that: the said edges and corners chamfering that presses down the following pressure surface of end, said chamfering are on its processing slope, corner angle position.

After adopting the present invention; Owing to press down the edges and corners chamfering of the following pressure surface of end, chamfering is that the area of pressure surface was less than datum level under it made on its processing slope, corner angle position; And then when actuating mechanism takes place slightly to rock; The following pressure surface that presses down end still is pressed onto datum level, can not exceed the scope of datum level, and that has guaranteed pressing tongs presses down stability, accuracy.

The specific embodiment

See Fig. 1: it comprises link 1, presses down end 2, and said link 1 connects the said end 2 that presses down, and presses down the edges and corners chamfering of the following pressure surface 3 of end 2, and chamfering is on its processing slope 4, corner angle position.

  

Claims (1)

1. the following pressure surface structure of pressing tongs, it comprises link, presses down end, and said link connects the said end that presses down, and it is characterized in that: the said edges and corners chamfering that presses down the following pressure surface of end, said chamfering be to process the slope in its corner angle position.
