Abstract
Description
Technical Field
[0001] This utility model belongs to the field of door and window processing technology, and specifically relates to a fixing device for cutting door and window profiles. Background Technology
[0002] During the installation of door and window profiles, the profiles need to be cut to the appropriate length according to the size requirements. When encountering corners, the ends of the profiles need to be cut into 45-degree bevels to meet the splicing requirements. The existing cutting machine saw blade has a single movement mode, and can only cut the profiles fixed on the worktable by horizontal movement. During cutting, the operator needs to manually adjust the placement angle of the profile on the worktable and press it firmly by hand for cutting. The above-mentioned profile fixing method has certain drawbacks: (1) When manually adjusting the placement angle of the profile, it is difficult to guarantee its accuracy, which affects the fit of the profile splicing; (2) The profile fixing effect is poor, and displacement is easy to occur during the cutting process, which affects the profile cutting quality. Therefore, it is necessary to propose a door and window profile cutting fixing device that can effectively fix the profile and meet the requirements of accurate cutting of 90° right angle and 45° bevel, so as to overcome the defects of the existing technology. Utility Model Content
[0003] This utility model addresses the shortcomings of the prior art by providing a fixing device for cutting door and window profiles. It uses two positioning strips to clamp and fix the profiles, preventing displacement during the cutting process. The tilt angle of the positioning strips can be adjusted using a straightedge, which effectively improves the accuracy of the bevel angle and facilitates subsequent splicing and assembly.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A fixing device for cutting door and window profiles includes a base, two positioning strips and a guide ruler. The base is provided with a sliding groove, and each positioning strip is provided with an elongated adjustment hole. A bolt passes through the elongated adjustment hole and is slidably connected to the elongated adjustment hole and the sliding groove. A nut is threaded onto the bolt. One side of the guide ruler is provided with a wing plate that abuts against the edge of the base. The included angles between the two sides of the guide ruler adjacent to the wing plate and the wing plate are 45° and 90°, respectively.
[0006] Preferably, there are two slide grooves, and there are two elongated adjustment holes and two bolts on the positioning strip, with each bolt cooperating with and connecting to the corresponding elongated adjustment hole and slide groove.
[0007] Preferably, the groove is a T-shaped groove, the head of the bolt is embedded in the T-shaped groove and slidably connected thereto, and the nut is located above the positioning strip.
[0008] Preferably, the base has at least one mounting groove, and the mounting groove contains screws for connecting to the cutting machine workbench.
[0009] Preferably, the mounting groove is a long, stepped groove, and the top of the screw is embedded in the mounting groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] (1) This utility model combines the sliding connection between the positioning strip and the base, and the sliding connection between the bolt and the long strip-shaped adjustment hole, which can lock and fix the position and tilt angle of the positioning strip, thereby meeting the fixing requirements of profiles of different specifications, sizes and tilt angles during cutting. In addition, with the angle positioning function of the ruler, the tilt angle of the positioning strip can be quickly and accurately adjusted. The operation is simple and convenient, and the accuracy of the slope angle is improved.
[0012] (2) This utility model uses two positioning strips to effectively clamp and fix the profile to be cut, preventing it from shifting during the cutting process. Moreover, the tilt angle of the positioning strips can be quickly adjusted according to actual needs with the help of external auxiliary tools. It has a wide range of applications and strong practicality. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] like Figure 1 As shown, a fixing device for cutting door and window profiles includes a base 1, two positioning strips 2, and a straightedge 3. The base has at least one mounting groove 8, within which a screw 9 is installed for connection to the cutting machine's worktable, enabling quick assembly between the base and the worktable. The mounting groove is a long, stepped groove to eliminate assembly errors. The top of the screw is embedded in the mounting groove to avoid affecting the placement of the profile on the upper part of the base. The base has a sliding groove 4, and each positioning strip has a long, narrow adjustment hole 5. A bolt 6 passes through the long, narrow adjustment hole, and the bolt is slidably connected to the long, narrow adjustment hole and the sliding groove. A nut 7 is threaded onto the bolt. Figure 2 As shown, the slide is a T-shaped groove, and the head of the bolt is embedded in the T-shaped groove and slidably connected to it. The nut is located above the positioning strip. This structure facilitates the adjustment of the horizontal position of the positioning strip on the base and also allows for easy rotation of the positioning strip to achieve angle adjustment. Tightening the corresponding nut locks and fixes the position and tilt angle of the positioning strip, which can meet the fixing needs of profiles with different specifications, sizes, and tilt angles. To improve the stability and firmness of the positioning strip, in this embodiment, there are two slides, and there are two elongated adjustment holes and two bolts on the positioning strip. Each bolt is connected to the corresponding elongated adjustment hole and slide.
[0022] like Figure 1 and Figure 3As shown, the straightedge is a right-angled trapezoid with a wing plate 301 on one side that abuts against the edge of the base. The angles between the two sides of the straightedge adjacent to the wing plate and the wing plate are 45° and 90° respectively. By utilizing the 45-degree inclined surface and 90-degree right-angled side of the wing plate to fit tightly against the positioning strip, the tilt angle of the positioning strip can be quickly and accurately adjusted, making the operation simple and convenient. The straightedge is movably placed on the base, and its position can be freely adjusted.
[0023] The specific operating steps for using this utility model are as follows:
[0024] (1) First, based on the cutting requirements of the profile, including the profile specifications and cutting angle, confirm the placement position and direction of the straightedge 3;
[0025] (2) Make one of the positioning strips 2 abut against the edge of the ruler 3 to adjust the angle of the positioning strip 2, and then tighten the two nuts 7 on the positioning strip to lock and fix the angle and position of the positioning strip 2.
[0026] (3) Place the profile to be cut on the base 1 with one side of the fixed positioning strip 2 close to it, then slide the other positioning strip 2 to fit tightly with the profile, and lock the corresponding nut 7 to achieve clamping and fixing of the profile to be cut.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
