Saw machine backing with auxiliary positioning device

Abstract

A sawing machine backup plate with auxiliary positioning device is applicable to being installed on a workbench which comprises opposite front end portion and back end portion; the workbench comprises a plane for supporting a workpiece; the sawing machine backup plate includes a pedestal installed on the back end portion and at least one auxiliary positioning device; the pedestal comprises at least one backup plate installed on the pedestal; the backup plate comprises a first pushing surface which is toward the front end portion and is perpendicular to the plane of the workbench; the auxiliary positioning device comprises a mounting seat which is able to slide along the direction in parallel to the first pushing surface, and a columnar auxiliary blocking element which is installed on the mounting seat; the auxiliary blocking element is able to transform between a blocking position of a second pushing surface and a shutting position, wherein the second pushing surface is perpendicular to the first pushing surface and the plane of the workbench.

Description

technical field [0001] The invention relates to a backing board of a sawing machine, in particular to a backing board of a sawing machine with an auxiliary positioning device. Background technique [0002] refer to figure 1 and figure 2 , is an existing sawing machine backing plate 1, which has a base 11 installed on the sawing machine table 10, a backing plate body 12 pivotally connected to the base 11, and several Combining holes 13 are provided at intervals in the base 11 along its length direction, and an auxiliary stopper 14 is detachably inserted in one of the combining holes 13 . [0003] During operation, a workpiece 15 will be placed on the workbench 10, so that one side edge of the workpiece 15 is against at least one of the base 11 and the backing body 12, and then, the auxiliary block The piece 14 is inserted into the joint hole 13 adjacent to the workpiece 15, so that the other side edge of the workpiece 15 is against the auxiliary stopper 14, whereby the op...

Problems solved by technology

[0004] However, due to this kind of plug-in configuration, the stop position of the auxiliary stopper 14 is restricted by the arrangement of the combination hole 13, so it cannot be applied to all sizes of workpieces 15. Moreover, the detachable plug-in structure is adopted, Not only is the structural stability poor, but the joint hole 13 is easy to shake out as the workpiece 15 resonates with force, and the independent part design is also easy to lose when the joint hole 13 is frequently replaced or inserted, or when the sawing machine is stored and moved. Therefore, the degree of freedom of operation, structural stability and ease of use still need to be improved.

[0005] Another kind of auxiliary block for the sawing machine leaning plate, as disclosed in U.S. Patent Nos. US5,337,641 and US5,768,966, respectively installs the track for the sliding seat on the top of the original sawing machine leaning plate, and will be in the shape of L The type of auxiliary stop is pivoted on the sliding seat. Although this type of slide rail fixed design can increase the degree of freedom of operation and reduce the trouble of parts falling off, but because the shape of the auxiliary stop is fixed, it will be turned over and folded. Occupies the movable space above the backing plate, therefore, it is necessary to specially loosen the sliding seat and move the auxiliary stopper away from the sawing unit to avoid interfering with the sawing process, but still has the disadvantages of complicated operation steps and inconvenient use
