Description

Woodworking plate cutting positioning frame

Technical Field

The invention relates to a cutting machine, a marble machine and a portable sawer board cutting positioning frame, in particular to a positioning structure of the positioning frame.

Background

As shown in fig. 1, the cutting machine, marble machine, and portable saw carpenter board cutting positioning frame generally includes two parallel sliding rods 1, a limiting ruler 2 and a saw mounting plate 3, the limiting ruler is fixed at one end of the sliding rod 1, the cutting machine, marble machine, and portable saw are mounted on the saw mounting plate 3, and can move along the sliding rod with the saw mounting plate 3, far away from or close to the limiting ruler 2. When the cutting device is used, the limiting ruler 2 is abutted against one side of a plate to be cut, the positioning frame is pushed, and when the limiting ruler 2 slides along one side of the plate to be cut, the saw blade of the cutting machine, the marble machine or the hand-held saw cuts the plate below through the saw blade hole 4.

The existing locating racks have no problem when cutting wide and large plates. However, when the panel is narrower, the panel dead weight is less, and panel is easy and then to slide when promoting the locating rack, again because of the locating rack has stretched out the both sides of panel, and fixing device can't be installed on these both sides and fixed panel, and among the practical experience, this kind of simple and easy locating rack can't reuse.

In addition, as the saw mounting plate 3 needs to move along the sliding rod 1, namely, the saw mounting plate is close to or far away from the limiting ruler 2, the saw mounting plate 3 needs to be connected with two sliding blocks 5 sleeved on the sliding rod 1 for movement, the sliding blocks 5 have certain wall thickness, the sliding rod 1 is jacked up by the wall thickness at the bottom, the sliding rod 1 at the limiting ruler 2 is abutted against a plate to be cut, and therefore, a certain amount of inclination is provided for a saw blade of the cutting machine, the marble machine or the hand saw, and the edge of the cut plate is not vertical.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

As shown in fig. 2-6, a woodworking plate cutting positioning frame comprises two parallel sliding rods 1, a limiting ruler 2 and a saw mounting plate 3, the saw mounting plate 3 is fixed at one end of the sliding rod 1, the limiting ruler 2 is connected with two sliding blocks 5, the two sliding blocks 5 are respectively sleeved on the two sliding rods 1, a mounting plate 6 is arranged at the bottom of one side of the sliding block 5 facing the saw mounting plate 3, the limiting ruler 2 is mounted at the bottom of the mounting plate 6, one sides of the positioning ruler 2 and the mounting plate 6, which are close to the saw mounting plate 3, are aligned, two raised convex plates 7 are respectively arranged at two ends of the saw mounting plate 3, a tongue piece 8 corresponding to the convex plate 7 is arranged on the sliding rod 1, the bottom of the tongue piece 8 is not lower than the bottom of the sliding rod 1, the bottom of the convex plate 7 is arranged at the upper part of the tongue piece 8, so that the bottom of the saw mounting plate 3 is flush with the bottom of the sliding block 1, the gap 9 is not smaller than the wall thickness of the sliding block 5, the saw mounting plate 30 is provided with a saw blade hole 4 and a saw fixing device, and the top of the sliding block 5 is provided with a tightening device 10 used for fixing the sliding block 5 on the sliding rod 1.

In this embodiment, the saw fixing device includes an arc-shaped pressing bar 11 and a U-shaped blade 12 matched with the arc-shaped pressing bar, when in use, the saw is fixed between the arc-shaped pressing bar and the U-shaped blade, a straight notch 13 is opened at the bottom of the U-shaped blade 12, and two bolts 14 with a distance smaller than the length of the straight notch 13 are arranged at the bottom of the saw mounting plate 3 and used for fixing the U-shaped blade 12.

Preferably, the slide bar is a square tube, and a ruler 15 is arranged at the top of the slide bar 1.

When the slider 5 drives the positioning ruler 2 to the saw blade (located in the saw blade hole 4), the mounting piece 6 and the positioning ruler 2 are both located below the sliding rod 1, a gap 9 is formed between the saw mounting plate 3 and the sliding rod 1 and is not smaller than the wall thickness of the slider 2, the slider can enter the gap, the horizontal distance between the positioning ruler and the saw blade can be as small as possible, and when the slider contacts the tongue piece at the limit, the horizontal distance between the positioning ruler and the saw blade hole can be 0. However, for safety reasons, the distance should not be made 0, and may be less than 1cm, to avoid contact of the blade with the positioning rule.

Because the sliding block is not contacted with the plate to be cut, the saw mounting frame and the sliding rod can be tightly attached to the surface of the material to be cut, and the cutting surface can be ensured to be vertical.

The saw fixing means, consisting of the curved batten 11 and the cooperating U-shaped blade 12, is prior art and is usually fixed to the saw mounting plate. This application is to the connected mode of U-shaped piece and saw mounting panel, sets up the notch at the bottom of the U-shaped piece promptly, through two bolted connection saw mounting panels, because the interval of two bolts is less than the length of notch, the U-shaped piece can be followed two bolts and removed about to finely tune the position to the U-shaped piece, adaptability is stronger when the installation saw.

As shown in fig. 7 (a), in the prior art, if the plate x to be cut is narrow, both ends of the positioning frame extend out of both sides of the plate, and fixing devices cannot be installed on both sides, otherwise, the movement of the positioning frame is blocked. As shown in fig. 7 (b), in the present application, as long as the width d1 of the plate x to be cut is wider than the distance d2 from the blade hole 4 to the edge of the positioning frame, a fixing device can be installed at the side away from the positioning rule 2 for fixing the plate x to be cut, thereby enlarging the application range.

The embodiments of the present invention are described only for the preferred embodiments of the present invention, and not for the limitation of the concept and scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall into the protection scope of the present invention, and the technical content of the present invention which is claimed is fully set forth in the claims.
