Abstract
The utility model relates to a composite saw working table self locking device, which comprises a working table and a supporting seat, wherein, the working table can be hinged on a left and a right cross beams of the supporting seat in a turnover way, and at least one cross beam is hollow; a draw rod capable of longitudinally moving is arranged in the hollow cross beam; the tail end of the draw rod is exposed to the end of the cross beam, and a spring is connected between the draw rod and the hollow cross beam; the side face of the working table closing to the hollow cross beam is provided with a cylindric pin extending outward, and the cylindric pin corresponding to a turnover shaft is positioned on one side of a working head. The draw rod is provided with two supporting blocks, the first supporting block corresponds to the position of the cylindric pin, and the second supporting block corresponds to the position of the cylindric pin after the cylindric pin is turned over. The supporting blocks are exposed to the inner side of the hollow cross beam, the matching face of the supporting blocks and the cylindric pin is a reversely inclined face, and the cylindric pin is matched with the supporting blocks. The utility model has high safety of the mechanism and is unlocked through people pulling a handle. The spring is arranged on the draw rod in series, so the composite saw working table self locking device avoids the safety accident caused by the disconnecting spring, the positioning area of the cylindric pin is enlarged, and the reliability of the positioning is ensured.
Description
(1) technical field
The utility model relates to a kind of multi-functional compound saw, especially about the self-locking structure of compound saw workbench.
(2) background technology
Compound saw in the market includes bench saw and two kinds of patterns of mitre saw of mutual switching, when workbench faces up, when working head is positioned on the work top, uses as mitre saw; Behind workbench Rotate 180 °, working head rotates face down in company with workbench, uses as bench saw.No matter bench saw or mitre saw, workbench all needs to fixedly positioning, in case working platform overturning during work all can cause the generation of security incident.Germany DELTA company production model is the compound saw of CMT01, adopt the self-locking device of four-bar linkage structure as workbench, as shown in Figure 1, described four connecting rods are fixing with support 2 by axle 1, wherein an axle is provided with the extension spring 3 that two ends are connected with locating piece 4, support 2 respectively, in case extension spring was lost efficacy, workbench overturns under the effect of gravity, will cause the generation of accident.Simultaneously, as shown in Figure 1, because structural limitations, what the head of the locating piece of straight pin must be done on the support table is very short, and the processing request height of locating piece is in addition because locating piece head lifting surface area is little, the location that only depends on extension spring to realize entire mechanism, in case the extension spring timeliness, consequence is hardly imaginable.
(3) summary of the invention
The utility model has solved existing compound saw self-locking structure and had lost efficacy easily and the demanding shortcoming of processing technology, and the compound saw workbench self-locking device that a kind of self-locking is effective, safe, cost is low is provided.
For this reason, the utility model is taked following technical scheme:
Compound saw workbench self-locking device, include workbench, supporting seat, described workbench is hinged on the left and right crossbeam of described supporting seat turningly, at least one crossbeam hollow, described hollow cross is built-in with the pull bar that can vertically move, the end of described pull bar exposes beam-end, is connected with spring between pull bar and the hollow cross; Described workbench has overhanging straight pin by the side of hollow cross, and straight pin is positioned at the first side of work with respect to trip shaft; Described pull bar is provided with two back-up blocks, first back-up block is corresponding with the straight pin position, and second back-up block is corresponding with the straight pin position after the upset, and back-up block exposes the hollow cross inboard, the mating surface of back-up block and straight pin is a contra bevel, and described straight pin cooperates with back-up block.
Be connected with connecting rod between described back-up block and the pull bar, described crossbeam is provided with the guide groove of described connecting rod.
Described back-up block upper end is acclivitous inclined plane from front to back.
Employing the utlity model has following advantage: 1, mechanism is safe, necessary artificial pulling handle release when needing transformation working pattern; 2, the spring string is contained on the pull bar, has avoided because the security incident that the workbench that the spring disconnection causes overturns and causes thus certainly; So the area that 3, has increased the straight pin location has guaranteed the reliability of location; 4, back-up block upper end is acclivitous inclined plane from front to back, can regulate the straight pin that causes because of machining accuracy or material deformation etc. and the stationary positioned gap between the back-up block automatically, makes the compact assembling structure non-loosening; 5, reduce cost, guaranteed security and the reliability used.

(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing 2-6, a kind of compound saw workbench self-locking device, include workbench 5, supporting seat 6, described workbench is hinged on the left crossbeam 7, right crossbeam 8 of described supporting seat turningly, at least one crossbeam hollow wherein, and described hollow cross is built-in with the pull bar 9 that can vertically move, the end of described pull bar exposes beam-end, handle 15 and pull bar are terminal to be connected, and is connected with spring 10 between pull bar and the hollow cross, and the two ends of spring withstand on respectively on locating piece on the pull bar, the beam-end; Described workbench has overhanging straight pin 11 by the side of hollow cross, and straight pin is positioned at working head 16 1 sides with respect to trip shaft; Described pull bar is provided with two back-up blocks, first back-up block 12 is corresponding with the straight pin position, and second back-up block 13 is corresponding with the straight pin position after the upset, and back-up block exposes the hollow cross inboard, the mating surface of back-up block and straight pin is a contra bevel, and described straight pin cooperates with back-up block.Be connected with connecting rod between described back-up block and the pull bar 9, described crossbeam is provided with the guide groove of described connecting rod.Described back-up block upper end is acclivitous inclined plane from front to back.
Workbench can around trip shaft 14 on 180 ° of vertical directions back and forth upset realize two kinds of patterns conversion of work: the pulling handle, first back-up block and straight pin are broken away from, the upset workbench is run into second back-up block up to the opposite side of work top, spacingly loose one's grip after stuck, mechanism finishes self-locking moment in this, and pattern converts.
The realization of self-locking mechanism: the folk prescription that leans on spring has kept the self-locking performance of mechanism to the active force pushing drawing rod.The contra bevel that contacts with straight pin by back-up block during translative mode and the relative motion of straight pin are finished.
