Description

Technical Field

[0001] This utility model belongs to the field of split-type sawing technology, specifically relating to a push saw mechanism for a sawing machine. Background Technology

[0002] Cutting is one of the most common processes in aluminum profile processing. A saw is the most frequently used tool for cutting aluminum profiles. When using a saw, the aluminum profile is fixed by a clamping assembly, and then the saw blade cuts it. The advantage of a split-type saw is that the two tables can be separated after cutting, thus preventing debris from sticking to the cut profile. However, when cutting profiles, a movable cutting device is needed. This involves pushing the saw blade to cut the profile. A search revealed that application number "201811015003.7" discloses a "split-type automatic saw," which describes a drive assembly including a drive cylinder and drive guide rails disposed on both sides of the drive cylinder. The drive cylinder extends with a drive output rod. The output direction of the output rod is parallel to the drive guide rail. The drive output rod is connected to a drive plate, which is movably connected to the drive guide rail. The sawing device is mounted on the drive plate. In the above-mentioned split sawing machine, the sawing device is moved by the drive cylinder to cut the profile. However, the drive stroke of the extension end of the drive cylinder is generally fixed, which is inconvenient in terms of stroke control. As a result, the saw blade will be fully extended when the drive cylinder is working. However, this method will cause the saw blade to fully extend to cut the profile and then retract when cutting smaller profiles. This process will affect the cutting efficiency of the profile. Moreover, the extension end of the drive cylinder is almost instantaneous when working. It reaches the maximum stroke immediately after pumping air. This method will cause damage to the saw blade. Therefore, this method will also affect the cutting effect when cutting profiles. Utility Model Content

[0003] The purpose of this utility model is to provide a push saw mechanism for a sawing machine, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a push saw mechanism for a sawing machine, comprising a push component mounted on the cutting frame of the sawing machine, a base plate mounted on the top of the push component, and a cutting component mounted on the top of the base plate;

[0005] The pushing component includes two guide rails and a guide bar mounted on the cutting machine frame. A slider is slidably mounted on the surface of the guide rails. The base plate is fixedly mounted on the surface of the slider. A drive tooth groove is opened on the side of the guide bar. The drive tooth groove meshes with a drive gear. The drive gear is connected to the output end of a reducer. The input end of the reducer is connected to the output shaft of a servo motor.

[0006] As a preferred technical solution of this utility model, the cutting assembly includes a motor base mounted on the top of a base plate, a drive motor mounted on the top of the motor base, a first limiting plate mounted on the surface of the output shaft of the drive motor, a cutting saw blade sleeved on the output shaft of the drive motor, and a second limiting plate sleeved on one side of the output shaft of the drive motor located on the cutting saw blade. The end of the output shaft of the drive motor has an external thread, and a limiting nut is threadedly connected to the end of the output shaft of the drive motor. The cutting saw blade is clamped and fixed between the first limiting plate and the second limiting plate by the limiting nut.

[0007] As a preferred technical solution of this utility model, the surface of the base plate is provided with a plurality of first screw holes, the surface of the reducer is provided with a U-shaped protective plate, the drive gear is located inside the U-shaped protective plate, the top of the U-shaped protective plate is provided with a second screw hole, and the U-shaped protective plate and the base plate are fixed by screws that are threadedly connected to the first screw holes and the second screw holes.

[0008] As a preferred technical solution of this utility model, the surface of the base plate has a plurality of third screw holes, and the surface of the motor base has a through strip groove. The motor base and the base plate are fixed by bolts that are threadedly connected to the internal threads of the strip groove and the third screw holes.

[0009] As a preferred technical solution of this utility model, receivers of photoelectric switches are installed on both sides of the surface of the base plate, and transmitters of photoelectric switches are installed on both sides of the cutting frame. The receivers and transmitters of the photoelectric switches are electrically connected to the servo motor through the controller of the sawing machine, thereby controlling the pushing stroke of the cutting saw blade in this way.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the servo motor drives the drive gear to rotate, and the drive gear, in conjunction with the drive tooth groove, enables the base plate to move along the guide rail. The photoelectric switch can control the movement stroke of the base plate, thereby controlling the movement stroke of the cutting component. The movement stroke of the cutting component can be adjusted according to the profile of different sizes, so that the cutting component can completely cut the profile without excessive movement. This method can improve the cutting efficiency of the profile. Moreover, the speed of the base plate is relatively slow due to the action of the reducer, so the profile can be cut better without damaging the saw blade and improving the flatness of the cut surface.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 The present invention provides the following technical solution: a push saw mechanism for a sawing machine, including a push component 1 installed on the cutting frame of the sawing machine, a base plate 2 installed on the top of the push component 1, and a cutting component 3 installed on the top of the base plate 2.

[0020] In this embodiment, the pushing component 1 includes two guide rails 101 and a guide bar 102 mounted on the cutting frame. A slider 103 is slidably mounted on the surface of the guide rails 101. The base plate 2 is fixedly mounted on the surface of the slider 103. A drive tooth groove 104 is provided on the side of the guide bar 102. The drive tooth groove 104 is meshed with a drive gear 105. The drive gear 105 is connected to the output end of the reducer 106. The input end of the reducer 106 is connected to the output shaft of the servo motor 107.

[0021] Specifically, the servo motor 107 drives the drive gear 105 to rotate, and the drive gear 105 meshes with the drive tooth groove 104. Therefore, in this way, the base plate 2 can drive the slider 103 to move along the guide rail 101. The speed reducer 106 can effectively reduce the speed of the drive gear 105. Therefore, in this way, the base plate 2 drives the cutting component 3 to slowly approach the profile to cut the profile. This method not only does not damage the cutting saw blade 304, but also can cut the profile better and effectively improve the flatness of the profile cutting surface.

[0022] In this embodiment, the cutting assembly 3 includes a motor base 301 mounted on the top of the base plate 2, a drive motor 302 mounted on the top of the motor base 301, a first limiting plate 303 mounted on the surface of the output shaft of the drive motor 302, a cutting saw blade 304 sleeved on the output shaft of the drive motor 302, a second limiting plate 305 sleeved on the output shaft of the drive motor 302 on one side of the cutting saw blade 304, an external thread 306 opened at the end of the output shaft of the drive motor 302, and a limiting nut 307 threadedly connected to the end of the output shaft of the drive motor 302.

[0023] Specifically, the cutting saw blade 304 is fitted onto the output shaft of the drive motor 302, and then the second limiting plate 305 is fitted onto the output shaft of the drive motor 302 and the limiting nut 307 is tightened. The limiting nut 307 makes the cutting saw blade 304 tightly clamped and fixed between the first limiting plate 303 and the second limiting plate 305. This method facilitates the replacement of the cutting saw blade 304.

[0024] In this embodiment, the surface of the base plate 2 is provided with a plurality of first screw holes 4, the surface of the reducer 106 is provided with a U-shaped protective plate 5, the drive gear 105 is located inside the U-shaped protective plate 5, the top of the U-shaped protective plate 5 is provided with a second screw hole 6, and the U-shaped protective plate 5 and the base plate 2 are fixed by screws that are internally threaded to the first screw holes 4 and the second screw holes 6.

[0025] Specifically, the U-shaped protective plate 5 can be easily fixed by the first screw hole 4 and the second screw hole 6. The U-shaped protective plate 5 allows the base plate 2 to drive the slider 103 to move along the guide rail 101 when the servo motor 107 drives the drive gear 105 to rotate. This method also facilitates the maintenance of the servo motor 107, the reducer 106 and the drive gear 105.

[0026] In this embodiment, the surface of the base plate 2 has multiple third screw holes 7, and the surface of the motor base 301 has a through strip groove 8. The motor base 301 and the base plate 2 are fixed by bolts that are internally threaded to the strip groove 8 and the third screw holes 7.

[0027] Specifically, this method facilitates the disassembly of the motor mount 301, thereby making it easier to maintain the drive motor 302.

[0028] In this embodiment, receivers 9 of through-beam photoelectric switches are installed on both sides of the surface of the base plate 2, and transmitters 10 of through-beam photoelectric switches are installed on both sides of the cutting frame.

[0029] Specifically, the receiver 9 and transmitter 10 of the through-beam photoelectric switch are electrically connected to the servo motor 107 through the controller of the sawing machine, thereby controlling the pushing stroke of the cutting saw blade 304.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
