Abstract

The utility model relates to a carpentry bench saw workpiece cutting length positioner (commonly known as a positioning device of a backer), in particular to a carpentry bench saw workpiece cutting length positioner utilizing the electromagnetism guide rail. The carpentry bench saw workpiece cutting length positioner is installed on the workbench with a circular saw and is characterized in that the positioning device comprises the backer, two parallel guide rails and two positioners, the parallel guide rails are arranged on the workbench, the backer is horizontally placed on the two parallel guide rails and is perpendicular to the guide rails, two positioners are installed on the backer and respectively placed on the two joints of the backer and the guide rails. The carpentry bench saw workpiece cutting length positioner has the advantages of being simple in manufacturing the positioning device, low in cost and capable of greatly saving the manpower, substantially reducing the time of assembling and detaching, and improving the the work efficiency effectively.

Description

A kind of woodworking table saw work piece cut length locator

Technical field

The utility model relates to a kind of woodworking table saw work piece cut length locator (being commonly called as backer's positioner), specially refers to a kind of woodworking table saw work piece cut length locator that utilizes the electromagnetism guide rail.

Background technology

Bench saw can be used for cut workpiece, for example plate.Bench saw generally comprises the annular saw that links with motor.The known bench saw that has two types, a kind of fixation workpiece cordwood saw unit, a kind of stationary saw unit activity workpiece, wherein, be that known type is in the plug-type bench saw, workpiece is fixed, and with cut workpiece, in a single day workpiece is cut to finish and namely allows saw push away the part that goes into operation the operator subsequently towards workpiece pulling saw unit.In actual use, because the required difference that reaches the cutting standard of workpiece, and moveable workpiece is than the more easy safety in cordwood saw unit, generally be that workpiece is against the upper cutting of conveniently sawing with the location that obtains workpiece of bench saw backer, so the location of workpiece is exactly bench saw backer's location in fact, in the tradition, the mechanical means bench saw backer of normal operation heaviness is fixed on the pedestal, fix as the bench saw backer is fixed on the pedestal or use strange his physical mechanical mode with iron nail, although this kind fixed form can be stablized the bench saw backer, but inconvenient bench saw backer locates for the second time, needs to consume larger manpower in the use procedure.

The utility model content

The utility model purpose is to provide a kind of easily labour-saving woodworking table saw work piece cut length locator.

The utility model is achieved through the following technical solutions:

A kind of woodworking table saw work piece cut length locator, it is installed on the workbench with annular saw, it is characterized in that: described positioner comprises backer, two parallel guide rails and two locators, described closed slide is installed on the workbench, described backer is shelved on two closed slides perpendicular to the level of guide rail, described two locators are installed on the backer, lay respectively at backer and guide rail junction.

Wherein: described guide rail is iron bar.

Wherein: described locator is electromagnet.

Wherein: described positioner is comprised of the locator that is installed on the backer of the closed slide more than two and respective amount.

Principle of the present utility model is: in use, the bench saw backer is fixed on the locator that is used in conjunction with parallel guide means, locator is for switching on regard to the magnetic electromagnet of tool, adjusting bench saw backer position when satisfying the workpiece process requirements, electromagnet is in off-position, the backer can be on guide rail voluntary activity, after the backer is fixed to desired location, the electromagnet energising is produced magnetic field, with electromagnet only being adsorbed on the iron bar in the guide rail, just the bench saw backer has been fixed on the desired position.When work piece cut is complete when need adjusting the backer position, only need the energising of tripping magnet, just Mobile electromagnetic iron easily, adjust the bench saw backer to the desired position, energising can be fixed on electromagnet on the guide rail iron bar again again, and in the time of need not using, cutting off the electricity supply gets final product.

The beneficial effects of the utility model are that positioner of the present utility model is made simply, and are with low cost, can greatly save manpower, significantly save and dismount and mount ETL estimated time of loading, Effective Raise operating efficiency.

Description of drawings

Come the utility model is further specified below by Figure of description.

Fig. 1 is top view of the present utility model;

Fig. 2 is side view of the present utility model.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further specified, but the utility model is not caused any restriction.

As shown in Figure 1, 2, a kind of woodworking table saw work piece cut length locator comprises workbench 1, annular saw 2, backer 3, closed slide 4 locators.

Electromagnet 5 is fixed on the backer 3, and backer 3 is shelved on two closed slides 4 perpendicular to the level of guide rail 4, and it is electromagnet 5 that backer and guide rail junction are fixed with locator.Electromagnet 5 can be on guide rail 4 along the guide rail activity to adjust required backer position, guide rail is iron bar, when definite backer's desired location, switch on to electromagnet, being about to electromagnet is fixed on electromagnet and backer on the iron bar desired location by electromagnetic attraction, cutting off the electricity supply equals just to unclamp the fixing of electromagnet and guide rail, has saved greatly manpower and time.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
