Vertical positioning device for profile sawing

Abstract

This utility model relates to a vertical positioning device for profile sawing, including a worktable with a vertically mounted backing plate. The front end of the backing plate serves as a positioning surface, and an opening is provided on the backing plate. A locator is located behind the backing plate and connected to a positioning drive mechanism. Driven by the positioning drive mechanism, the locator extends through the opening and engages with the positioning surface to vertically position the profile. When the rear ends of aluminum profiles A and B of a thermally broken aluminum alloy are aligned, vertical positioning is achieved solely through the positioning surface of the backing plate. When the rear ends of aluminum profiles A and B are misaligned, the locator extends through the opening and acts on aluminum profile A, while aluminum profile B acts on the positioning surface of the backing plate, thus achieving vertical positioning. This device solves the problem of vertical positioning for different profiles, has a simple and practical overall structure, meets the vertical positioning requirements of various profiles, and improves the quality of profile sawing.

Description

Technical Field

[0001] This utility model relates to the field of door and window profile sawing technology, and in particular to a vertical positioning device for profile sawing. Background Technology

[0002] Sawing is an essential processing step in door and window production. To improve processing efficiency, current technology commonly uses sawing machining centers or milling and sawing machining centers to complete the sawing process of profiles. Regardless of the type of machining center, the profile needs to be positioned and clamped during sawing. Horizontal clamping is mainly achieved by the cooperation of a backing plate and multiple clamping cylinders and clamping blocks set in front. The backing plate mainly serves to vertically position the rear end of the profile.

[0003] In actual product manufacturing, thermally broken aluminum profiles consist of aluminum profile A, thermal break strips, and aluminum profile B. The thermal break strip connects aluminum profile A and aluminum profile B together. In most thermally broken aluminum designs, the rear ends of aluminum profiles A and B are vertically aligned (i.e., the surfaces acting on the backing plate), so vertical positioning can be achieved simply by using the backing plate. However, with the diversification of profile designs and the automated production of sub-frame profiles, the rear ends of aluminum profiles A and B in some thermally broken aluminum profiles are no longer aligned (see attached diagram). Figure 4 This results in only one of aluminum profiles A and B being able to rest on the backing plate, while the other cannot. Since the thermal break strip connection is not a rigid connection, it is easy for the thermally broken aluminum profile to fail to achieve vertical positioning, ultimately affecting the sawing accuracy.

[0004] In summary, how to achieve vertical positioning of different profiles has become a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a vertical positioning device for profile sawing, which solves the vertical positioning problem of different profiles and significantly improves the quality of sawing.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A vertical positioning device for profile sawing includes a worktable, on which a backing plate is vertically provided. The front end of the backing plate is a positioning surface, and an opening is provided on the backing plate. A locator is provided behind the backing plate, and the locator is connected to a positioning drive mechanism. The locator can extend through the opening and cooperate with the positioning surface to vertically position the profile under the drive of the positioning drive mechanism.

[0007] The positioning drive mechanism includes a motor located at the rear end of the back plate. The motor is connected to a rotating shaft via a coupling. The rotating shaft is rotatably mounted on the back plate via a bearing with a seat. A mounting base is provided at the lower end of the rotating shaft. The mounting base is provided with the positioner, which is a roller. The mounting base and the roller on it rotate together with the rotating shaft.

[0008] The positioning drive mechanism is a linear module, and the positioner is provided on the slide of the linear module. The positioner is a positioning block or a roller.

[0009] The present invention adopts the above solution and has the following beneficial effects: By designing an opening on the backplate and incorporating a matching positioner, the front face of the backplate serves as the positioning surface, while the positioner provides auxiliary positioning. When the rear faces of aluminum profiles A and B in the thermally broken aluminum frame are aligned, only the positioning surface of the backplate is needed for vertical positioning. When the rear faces of aluminum profiles A and B are not aligned, the positioner extends through the opening and acts on aluminum profile A. The specific distance the positioner extends depends on the dimensions of the thermally broken aluminum frame. Aluminum profile B acts on the positioning surface of the backplate, thus achieving vertical positioning. The overall structure is simple and practical, meeting the vertical positioning requirements of different profiles and improving the quality of profile sawing. Attached Figure Description

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0016] Example 1 like Figure 1-2 As shown, a vertical positioning device for profile sawing includes a worktable 1, a backing plate 2 vertically provided on the worktable 1, a positioning surface 3 at the front end of the backing plate 2, an opening 4 on the backing plate 1, and a locator 5 provided behind the backing plate 2. The locator 5 is connected to a positioning drive mechanism 6. The locator 5 can extend through the opening 4 and cooperate with the positioning surface 3 to perform vertical positioning of the profile under the drive of the positioning drive mechanism 6. By designing an opening 4 on the backing plate 2 and a matching locator 5, the front face of the backing plate 2 can serve as the positioning surface 3, with the locator 5 providing auxiliary positioning. When the rear faces of aluminum profiles A701 and B703 of the thermally broken aluminum 7 are aligned, only the positioning surface 3 of the backing plate 2 is needed for vertical positioning. When the rear faces of aluminum profiles A701 and B703 are not aligned, the locator 5 extends through the opening 4 and acts on aluminum profile A701. The specific distance the locator 5 extends depends on the dimensions of the thermally broken aluminum 7. Aluminum profile B703 acts on the positioning surface 3 of the backing plate 2, thus achieving vertical positioning. The overall structure is simple and practical, meeting the vertical positioning requirements of different thermally broken aluminum 7 profiles and improving the quality of profile sawing.

[0017] The positioning drive mechanism 6 includes a motor 601 located at the rear end of the back plate 2. The motor 601 is connected to a rotating shaft 603 via a coupling 602. The rotating shaft 603 is rotatably mounted on the back plate 2 via a bearing 604. A mounting base 605 is provided at the lower end of the rotating shaft 603, and the positioner 5, which is a roller 501, is mounted on the mounting base 605. The mounting base 605 and the roller 501 rotate together with the rotating shaft 603. The positioner 5 extends through the opening 4 using rotational motion. This structure is compact, occupies little space, and is less likely to interfere with other components.

[0018] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 3 As shown, the positioning drive mechanism 6 is a linear module 606, and the positioner 5 is provided on the slide 607 of the linear module 606. The positioner 5 is either a positioning block 502 or a roller 501. The positioner 5 extends through the opening 4 by linear motion, and the linear module 606 can be set on the worktable.

[0019] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0020] Any aspects of this utility model not described in detail are known to those skilled in the art.
