Description

Technical Field:

[0001] The utility model relates to the technical field of tooth - cutting processing of broken - bridge aluminum profiles, in particular to a device for adjusting the distance between tooth - cutting knives. Background Art:

[0002] The broken - bridge aluminum, also known as the heat - insulating broken - bridge aluminum profile, is widely used in the construction industry, such as doors, windows, sun rooms, etc. The current forming process of broken - bridge aluminum mainly includes three steps: tooth - cutting, strip - threading, and rolling and compounding. Among them, the tooth - cutting process requires a tooth - cutting machine, or a tooth - cutting and strip - threading integrated machine. Existing broken - bridge aluminum profiles usually have two slots for installing two heat - insulating strips. Therefore, whether it is a tooth - cutting machine or a tooth - cutting and strip - threading integrated machine, usually two tooth - cutting knives are required to perform tooth - cutting processing on the profile. In order to meet the tooth - cutting requirements of different profiles, the existing technology requires that the tooth - cutting knives have the ability to adjust height and distance. Currently, the distance adjustment of tooth - cutting knives is mainly divided into two types. One is to independently control the two tooth - cutting knives. Each tooth - cutting knife can achieve vertical and longitudinal adjustment. The specific structure can refer to a tooth - cutting machine for broken - bridge heat - insulating profiles disclosed in a Chinese patent (authorization announcement number: CN203853632U). This structure is generally applicable to tooth - cutting machines and has the advantage of flexible adjustment. It can realize the vertical dislocation adjustment of the two tooth - cutting knives and can meet the tooth - cutting processing of more types of profiles. However, because it requires two two - axis electric sliding tables, the cost is relatively high. The other is to integrate the two tooth - cutting knives onto a transmission shaft, and the two tooth - cutting knives share a set of two - axis electric sliding tables to achieve vertical and longitudinal distance adjustment. Obviously, this structure has a lower cost, but the adjustment flexibility is relatively poor. In particular, it is difficult to achieve the vertical dislocation adjustment of the two tooth - cutting knives, or it can only be achieved by replacing the tooth - cutting knives.

[0003] With the continuous development of the construction industry, especially the vigorous development of the door and window manufacturing industry, in the design of broken - bridge aluminum, the heights of the two slots are mostly the same. As a result, the situation where vertical dislocation adjustment of the two tooth - cutting knives is required is becoming less and less. In addition, the integrated design of the forming process of broken - bridge aluminum has been realized, integrating tooth - cutting, strip - threading, and rolling and compounding into a production - line - type processing center. In particular, tooth - cutting and strip - threading are integrated into one, that is, tooth - cutting and strip - threading processing are completed in one step. Therefore, the solution of integrating the two tooth - cutting knives onto a transmission shaft has been widely used. In practical applications, although the situation where vertical dislocation of the two tooth - cutting knives is required is becoming less and less, due to the different widths of the profile designs, the distance adjustment of the two tooth - cutting knives is still essential. Therefore, how to realize the distance adjustment of the two tooth - cutting knives on the transmission shaft has become a new technical problem.

[0004] In order to achieve the spacing adjustment of two toothed cutters, some attempts have been made in the prior art. Among them, the mainstream approach is to install a cutter shaft (or a screw cutter shaft, adjusted by a screw) at the end of the transmission shaft on the basis of the existing single toothed cutter installation structure, and install another toothed cutter on the cutter shaft. The cutter shaft can move relative to the transmission shaft to achieve spacing adjustment, and then the transmission shaft and the cutter shaft are locked by designing a locking mechanism. The specific structure can refer to a kind of AB surface synchronous toothing machine disclosed in a Chinese patent (authorization announcement number: CN220921534U). Although the spacing adjustment structure of the above-mentioned toothed cutters achieves spacing adjustment, there are some deep-seated technical problems in practical applications. For example, the cutter shaft and the transmission shaft are processed separately and connected mechanically, and the cutter shaft is suspended at the end of the transmission shaft, which not only leads to a decrease in the strength of the cutter shaft installation structure, but also has low transmission accuracy. In particular, the toothed cutter on the cutter shaft not only has the problem of unstable operation, but also is prone to the technical problem of "losing steps", which leads to a general toothing effect. Therefore, it is necessary to re-optimize the spacing adjustment structure of the two toothed cutters on the existing transmission shaft, in order to improve the structural strength under the premise of convenient adjustment.

Specific embodiments:

[0023] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of example with reference to the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0025] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0026] In the present invention, unless otherwise clearly defined and limited, terms such as "provided with", "set", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Such as Figures 1-5As shown in the figure, the spacing adjusting device for the tooth - opening cutter includes a transmission shaft 1. Along the axial direction of the transmission shaft 1, a cutter seat A2 and a guide shaft 3 are successively arranged. An opening cutter A4 is arranged on the cutter seat A2. A cutter seat B5 is slidably arranged on the guide shaft 3. An opening cutter B6 is arranged on the cutter seat B5. An adjusting hole 7 is arranged at the center of the guide shaft 3. An adjusting block 8 is slidably arranged in the adjusting hole 7. A guide keyway 9 communicating with the adjusting hole 7 is arranged on the side wall of the guide shaft 3. A key 10 is slidably arranged along the axial direction in the guide keyway 9. Screws A11 and screws B12 are respectively arranged on the cutter seat B5. The screw A11 is in threaded connection with the adjusting block 8, and the cutter seat B5 is locked on the guide shaft 3 by adjusting the screw A11. The screw B12 is in threaded connection with the key 10, and the key 10 slides together with the cutter seat B5. In this application, the cutter seat A2 and the guide shaft 3 are integrally formed on the basis of the existing transmission shaft 1, so that the strength of the main structure is enhanced; the slidable arrangement of the cutter seat B5 on the guide shaft 2 provides a basis for adjusting the spacing between the two opening cutters. On this basis, by designing the adjusting block 8 and the screw A11, it is realized that the cutter seat B5 is locked on the guide shaft 3 by tightening the screw A11, and the spacing of the cutter seat B5 is slidably adjusted on the guide shaft 3 by loosening the screw A11. By designing the guide keyway 9 and the key 10, not only the axial spacing can be adjusted, but also the loss of steps can be prevented, ensuring that the opening cutter B6 rotates synchronously with the transmission shaft 1.

[0028] The cutter seat A2 is designed as a cylinder. The diameter of the cutter seat A2 is larger than that of the guide shaft 3. The cutter seat A2 and the transmission shaft 1 are connected by a tapered structure. The specific structure of the cutter seat A2 is given. This cylindrical structure is beneficial to integrally forming with the transmission shaft 1 and has high structural strength.

[0029] The opening cutter A4 and the opening cutter B6 have the same structure, and an avoidance through - hole 13 is arranged at their centers. The diameter of the avoidance through - hole 13 is larger than that of the guide shaft 3. By designing the avoidance through - hole 13, it can be realized that the opening cutter A4 and the opening cutter B6 can pass through the guide shaft 3 for installation. The opening cutter A4 and the opening cutter B6 in this application belong to the prior art, and the difference is that the size of the avoidance through - hole 13 is adaptively increased to facilitate passing through the guide shaft 3. The installation of the opening cutter is relatively simple. Taking the installation of the opening cutter B6 as an example, a plurality of threaded holes 21 are arranged at intervals along the circumferential direction on the side end face of the cutter seat B5. Correspondingly, a plurality of installation holes 22 are designed on the opening cutter B6, and the screw 23 passes through the installation hole 22 and is connected with the threaded hole 21.

[0030] A guide through - hole 14 is arranged at the center of the cutter seat B5. The cutter seat B5 is slidably arranged on the guide shaft 3 through the guide through - hole 14. This meets the requirement of sliding to adjust the spacing.

[0031] A keyway 15 is provided on the inner wall of the tool holder B5. A part of the key 10 is arranged in the keyway 15, and the other part is arranged in the guiding keyway 9. A threaded hole B16 is provided on the key 10, and a mounting hole B17 is provided on the tool holder B5. The lower end of the screw B12 passes through the mounting hole B17 and is threadedly connected to the threaded hole B16. The specific installation structure of the tool holder B5 and the key 10 is given. While realizing the reliable installation of the key 10, the circumferential direction of the tool holder B5 is well limited, effectively solving the problem of the loss of steps of the gear cutting tool B6 and ensuring the synchronous rotation of the gear cutting tool B6 and the transmission shaft 1.

[0032] A mounting hole A18 is provided on the tool holder B5, a threaded hole A19 is provided on the adjusting block 8, an avoidance hole 20 is provided on the key 10, and the lower end of the screw A11 passes through the mounting hole A18, the avoidance hole 20 and the guiding keyway 8 in sequence and is connected to the threaded hole A19. The specific installation and locking structure form of the adjusting block 8 are given, and locking and loosening are carried out through threaded connection.

[0033] The adjusting hole 7 is a round hole, and the corresponding adjusting block 8 is cylindrical. The cylindrical structure has the advantages of being easy to process and having reliable locking.

[0034] The above specific implementation manners cannot be used as a limitation to the protection scope of the present utility model. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
