Description

Technical Field

[0001] This utility model relates to the technical field of door and window frame strip cutting equipment, specifically a cutting mechanism for a door and window frame strip cutting machine. Background Technology

[0002] A door and window frame strip serration machine is a machine specifically designed to press and form a toothed structure on door and window frame strips. After the toothed structure is formed at the connection between the door and window frame strip and the sealing strip, the connection performance between them is greatly improved, preventing the sealing strip from slipping and thus ensuring the sealing performance of the entire door and window during subsequent use. The serration mechanism used in the door and window frame strip serration machine generally has two serration mechanisms, one on the left and one on the right. Each of the two serration mechanisms is connected to a reduction motor that can move horizontally through a slide table. The slide table is also connected to a lifting seat, thereby enabling the machine to move closer to and further away from the door and window frame strip. The two serration mechanisms can simultaneously groove both sides of the door and window frame strip.

[0003] Currently, the tooth-cutting mechanism used in door and window frame strip cutting machines has a fixed connecting rod length. The inner side is connected to the output shaft of the geared motor through a connecting sleeve, and the outer side is connected to the tooth-cutting disc. Because the length is fixed, when there is an error in the size of the door and window frame strip, it is inefficient to manually adjust it numerically through the control terminal. Therefore, an improved technology is urgently needed to solve the above-mentioned problems in the existing technology. Summary of the Invention

[0004] The purpose of this utility model is to provide a tooth-cutting mechanism for a door and window frame tooth-cutting machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooth-cutting mechanism for a door and window frame strip tooth-cutting machine, comprising a shaft connecting sleeve, a guide cylinder, a locking bolt, a connecting plate, a guide rod, and a tooth-cutting disc. One end of the shaft connecting sleeve is open, and the other end of the shaft connecting sleeve is sealed. A guide cylinder is coaxially arranged at the sealed end. Several internally threaded sleeves are radially arranged on the side wall of the guide cylinder away from the shaft connecting sleeve. A locking bolt is fitted inside each internally threaded sleeve. A guide rod is arranged along the axial direction at one end of the connecting plate. The guide rod is movably fitted with the guide cylinder. The locking bolt is fastened to the side wall of the guide rod. Several positioning pins are arranged on the end of the connecting plate away from the guide rod. Several positioning holes are opened axially on the tooth-cutting disc. The positioning holes of the tooth-cutting disc correspond one-to-one with the positioning pins and are inserted into each other. The tooth-cutting disc is fastened to the connecting plate by the connecting bolt.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a tooth-cutting mechanism for a door and window frame strip tooth-cutting machine, including a shaft connecting sleeve 1, a guide cylinder 2, a locking bolt 3, a connecting plate 4, a guide rod 5, and a tooth-cutting disc 6. One end of the shaft connecting sleeve 1 is open, and the other end of the shaft connecting sleeve 1 is sealed and the guide cylinder 2 is coaxially arranged at the sealed end. A plurality of connecting holes 13 are radially opened on the side wall of the end of the shaft connecting sleeve 1 away from the guide cylinder 2. After the shaft connecting sleeve 1 is inserted into the output shaft of the reduction motor, the connection is achieved by the cooperation of the connecting holes 13 through the shaft pin. The shaft connecting sleeve 1 and the output shaft of the geared motor are connected. Several internally threaded sleeves 7 are radially arranged on the side wall of the guide cylinder 2 at the end away from the shaft connecting sleeve 1. Each internally threaded sleeve 7 is fitted with a locking bolt 3. A guide rod 5 is arranged at one end of the connecting disc 4 along the axial direction. Several reinforcing plates 14 are provided at the connection between the guide rod 5 and the connecting disc 4 to ensure the structural strength between the connecting disc 4 and the guide rod 5. The guide rod 5 is movably fitted with the guide cylinder 2, and the locking bolt 3 is tightly fitted with the side wall of the guide rod 5. Several positioning pins 8 are arranged at the end of the connecting disc 4 away from the guide rod 5. The ends of the positioning pins 8 are tapered to ensure that the positioning pins 8 can be smoothly inserted into the positioning holes 9. The geared disc 6 is axially... The toothed disc 6 is provided with several positioning holes 9. The positioning holes 9 of the toothed disc 6 correspond one-to-one with the positioning pins 8 and are inserted into each other. The toothed disc 6 is fastened to the connecting disc 4 by connecting bolts 10. The connecting disc 4 and the guide rod 5 are both provided with screw holes 11 at their center positions. The toothed disc 6 is provided with a countersunk hole 12 at its center position. The connecting bolts 10 pass through the countersunk hole 12 and are connected with the screw holes 11. This structure enables the toothed disc 6 and the connecting disc 4 to be connected by connecting bolts 10, and at the same time facilitates disassembly and replacement of the toothed disc 6. The outer edge of the toothed disc 6 is densely covered with tooth grooves along the axial direction. After the toothed disc 6 is pressed onto the toothed position of the door and window frame strip, the toothed disc 6 is used to open the corresponding position of the door and window frame strip through the tooth grooves.

[0016] Installation method and operating principle: Insert the guide rod 5 into the guide cylinder 2, then screw the locking bolt 3 into the internal thread sleeve 7. Next, select the appropriate toothed disc 6 according to the model of the door and window frame strip and the toothing requirements. Align the positioning holes 9 of the toothed disc 6 with the positioning pins 8 of the connecting disc 4 and insert them one by one. Then, use bolts and washers to fasten the toothed disc 6 and the connecting disc 4 to complete the assembly. In use, insert the shaft connecting sleeve 1 into the output shaft of the geared motor and fasten it with the shaft pin. Figure 3 As shown, based on the position of the groove in the door and window frame strip, the reduction motor is first adjusted via the slide table. If there is a slight error between the position of the toothed disc 6 and the position of the toothed section in the door and window frame strip, there is no need to adjust the slide table. Simply loosen each locking bolt 3, adjust the position of the guide rod 5 and the connecting plate 4, so that the position of the toothed disc 6 corresponds to the position of the toothed section in the door and window frame strip, and then tighten the locking bolt 3. This utility model has a reasonable structure. The toothed disc 6 is connected to the connecting plate 4, and the connecting plate 4 is slidably connected to the guide cylinder 2 via the guide rod 5. At the same time, the guide rod 5 is also positioned by the locking bolt 3. Since the toothed disc 6 can follow the lateral adjustment of the connecting plate 4 and the guide rod 5, the position of the toothed disc 6 can be quickly adjusted when there is a certain error in the door and window frame strip. This greatly improves efficiency compared to the manual adjustment of the slide table by CNC. At the same time, it greatly improves flexibility and applicability compared to the traditional fixed structure. The positioning holes 9 of the toothed disc 6 correspond one-to-one with the positioning pins 8 of the connecting plate 4 and are inserted into each other. This structure greatly improves the stability of the toothed disc 6.
