Abstract
The invention discloses an automatic positioning mechanism of an oblique cutting machine backup plate. The automatic positioning mechanism of the oblique cutting machine backup plate comprises a base (1), a rotary table (3) and a primary backup plate (2). The rotary table (3) is rotatably arranged on the base (1), the primary backup plate (2) is fixed on the base (1), and a secondary backup plate (5) which can stretch freely is arranged on the side, close to a notch of the rotary table (3), of the primary backup plate (2). A guide sliding chute (4) is formed in the rotary table (3), a guide pin (6) which is matched with the guide sliding chute (4) is arranged on the secondary backup plate (5), and when the rotary table (3) rotates, the guide pin (6) slides in the guide sliding chute (4) and drives the secondary backup plate (5) to make straight line movement relative to the primary backup plate (2). By the adoption of the structure, the automatic positioning mechanism of the oblique cutting machine backup plate has the advantages of being simple and reasonable in structure, convenient to assemble, safe and reliable to use, automatic in stretching and positioning, low in production cost and the like.
Description
Technical field
The invention relates to a kind of positioner of bias cutter backup plate, particularly a kind of along with bias cutter cutting angle changes and the bias cutter backup plate automatic positioning mechanism of automatic telescopic.
Background technology
Bias cutter is a kind of application various section bar cutting tools very widely, can require various section bars to cut into different angles according to difference, it has the features such as rotating speed is high, cutting speed is fast, easy for operation, applied widely, is widely used in all trades and professions.The bias cutter using is at present provided with manually operated plug-type secondary backup plate in order to reach the requirement of safety standard on main backup plate; when vertical cut, secondary backup plate is released; when cutting sth. askew, secondary backup plate is removed; but this structure usually can be forgotten secondary backup plate is removed when use is cut sth. askew; cause secondary backup plate to damage; safe distance between backup plate and saw blade be can not be guaranteed; do not reach the requirement of safety standard; do not have due safety guarantee effect, so design a kind of backup plate detent mechanism simple in structure, easy to assembly, automatic telescopic location, become a difficult problem in the industry.For this reason, many manufacturers and knowledgeable people are studied and develop for the problems referred to above, but not yet have so far desirable product to emerge on market.
Summary of the invention
The above-mentioned disadvantage existing for overcoming existing bias cutter backup plate detent mechanism, the object of the invention is to provide a kind of simple and reasonable, easy to assembly, safe and reliable, automatic telescopic location, bias cutter backup plate automatic positioning mechanism that production cost is low.
The invention solves the problems of the technologies described above adopted technical scheme, it comprises base, rotating disk, main backup plate, rotating disk is rotating to be arranged on base, main backup plate is fixed on base, described main backup plate is provided with the secondary backup plate of retractable near a side of rotating disk notch, rotating disk is provided with guide chute, and secondary backup plate is provided with the guide finger matching with guide chute, and guide finger slides and drives the relatively main backup plate traveling priority of secondary backup plate when dial rotation in gathering sill.
The further scheme of the invention, described main backup plate is provided with the positioning runner matching with secondary backup plate.
Adopt after said structure, compared with prior art have the following advantages and effect: the one, because rotating disk is provided with guide chute, main backup plate is provided with guide chute and matches and merge the secondary backup plate of retractable, when use is cut sth. askew, guide finger can slide and drive the relatively main backup plate traveling priority of secondary backup plate when dial rotation in gathering sill, make secondary backup plate remain consistent with the distance between saw blade, thereby reach the requirement of safety standard, play due safety guarantee effect.The 2nd, simple in structure, easy to assembly, good reliability, production cost are low, are convenient to promote the use of.

The specific embodiment
Shown in Fig. 1 to Fig. 4, specific embodiments for a kind of bias cutter backup plate of the invention automatic positioning mechanism, it comprises base 1, rotating disk 3, main backup plate 2, rotating disk 3 is rotating to be arranged on base 1, main backup plate 2 is fixed on base 1, described main backup plate 2 is provided with the secondary backup plate 5 of retractable near a side of rotating disk 3 notches, rotating disk 3 is provided with guide chute 4, secondary backup plate 5 is provided with the guide finger 6 matching with guide chute 4, guide finger 6 when rotating disk 3 rotates in the interior slip of gathering sill 4 and drive relatively main backup plate 2 traveling priorities of secondary backup plate 5.For the ease of secondary backup plate 5 traveling priority on main backup plate 2, described main backup plate 2 is provided with the positioning runner 7 matching with secondary backup plate 5.
Plan structure schematic diagram when Fig. 5 is the invention vertical cut state, Fig. 6 is the plan structure schematic diagram of the invention while directly cutting sth. askew state.When the invention regulating cutting angle rotates rotating disk 3, guide finger 6 on secondary backup plate 5 is at the interior relative sliding of gathering sill 4 of rotating disk 3, and drive secondary backup plate 5 traveling priority on the positioning runner 7 of main backup plate 2, make secondary backup plate 5 remain consistent with the distance between saw blade, thereby realize the function of automatically locating between secondary backup plate 5 and saw blade.
The above; just an embodiment of the invention, not makes any pro forma restriction to the invention, is not departing from the technical scheme basis of the invention; the simple modification of having done, equivalent variations or modification, all fall into the protection domain of the invention.
Claims (2)
