Technical Field

[0001] The utility model relates to the technical field of door frame processing, in particular to a door frame cutting machine. Background Art

[0002] The working principle of a door frame cutting machine may vary depending on the specific model and cutting method. Generally speaking, it uses cutting tools such as high-speed rotating blades, laser beams, or high-pressure gas to cut the door frame placed on a cutting table.

[0003] However, some traditional door frame cutting machines lack a length measuring mechanism and are unable to accurately measure and cut the door frame profiles of the required length according to actual needs. This means that in actual operation, the operator may need to manually measure or use other tools to assist in determining the cutting length, which not only increases the complexity of the operation, but may also affect the cutting accuracy and efficiency. Therefore, we propose a new type of door frame cutting machine. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0018] 1. This utility model utilizes a positioning mechanism to precisely measure and position the length of doorframe profiles. The positioning mechanism comprises a track, a slider, a column, a light barrier, and a positioning bolt. The operator adjusts the position of the light barrier by sliding the slider according to the preset doorframe profile cutting length. When the laser rangefinder indicates the distance equal to the preset length, the positioning bolt is rotated to secure the slider, ensuring that the light barrier is precisely positioned for the desired cutting length.

The cutting mechanism comprises a rotating base, a housing, a motor, and a cutting disc. When the motor is activated, it drives the cutting disc to rotate at high speed, generating a powerful cutting force. Simultaneously, the output of the laser rangefinder faces the light barrier, and the distance between the laser rangefinder and the cutting disc is pre-set to be equal to the distance from the light barrier to the cutting point. This ensures that the cutting disc precisely cuts the door frame profile along the pre-set cutting line, ensuring both accuracy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model provides a technical solution:

[0031] See also Figures 1 to 3 The door frame cutting machine comprises a workbench 1 , and a positioning mechanism 2 is provided on the top of the workbench 1 .

[0032] The positioning mechanism 2 includes a track 21, a slider 22 is slidably connected to the outer side of the track 21, a column 23 is fixedly installed at the center of the top of the slider 22, a light baffle 24 is fixedly installed on the inner side of the column 23, and the internal thread of the slider 22 is connected to a positioning bolt 25. Through the arrangement of the track 21, the slider 22, the column 23, the light baffle 24 and the positioning bolt 25, the precise adjustment and positioning of the door frame profile length is achieved, ensuring that the laser rangefinder 5 can accurately measure and locate the cutting starting point, thereby simplifying the traditional manual measurement process and improving the cutting accuracy and efficiency.

[0033] Furthermore, the track 21 is fixedly installed on the top of the workbench 1. By fixing the track 21 on the top of the workbench 1, a stable sliding path is provided for the slider 22, ensuring that the positioning mechanism 2 can accurately adjust the position of the light baffle 24, thereby cooperating with the laser rangefinder 5 to achieve accurate measurement and positioning of the door frame profile length.

[0034] Furthermore, the positioning bolt 25 passes through the slider 22, and the lower end of the positioning bolt 25 contacts the top of the track 21. By passing the positioning bolt 25 through the slider 22 and contacting the top of the track 21, the rotation generates friction to fix the slider 22, ensuring that the light baffle 24 is positioned accurately and stably, thereby ensuring the accuracy of the cutting length of the door frame profile and the stability of the cutting process.

[0035] Furthermore, a clamping mechanism 3 is provided on the right side of the positioning mechanism 2, and the clamping mechanism 3 includes a base plate 31 fixedly installed on the right side of the light baffle 24, an electric telescopic rod 32 is fixedly installed on the inner side of the base plate 31, and a clamping plate 33 is fixedly installed on the output end of the electric telescopic rod 32, and a door frame profile 34 is provided on the inner side of the clamping plate 33. The clamping plate 33 is driven by the electric telescopic rod 32 to clamp the door frame profile 34, ensuring that it is stable and motionless during the cutting process, thereby improving the cutting accuracy and safety, and simplifying the steps of manually fixing the profile in the traditional door frame cutting machine.

[0036] Furthermore, a cutting mechanism 4 is provided above the door frame profile 34. The cutting mechanism 4 includes a rotating base 41 fixedly mounted on the upper right corner of the workbench 1. The internal rotation of the rotating base 41 is connected to a shell 42. A motor 43 is fixedly mounted on the outer side of the shell 42. A cutting blade 44 is fixedly mounted on the output end of the motor 43. The cutting blade 44 is driven by the motor 43 to rotate at a high speed to achieve precise cutting of the door frame profile 34. Its design not only improves the cutting efficiency, but also ensures the accuracy and stability of the cutting, meeting the high-precision requirements of door frame processing.

[0037] Furthermore, the cutting blade 44 is located in the inner cavity of the shell 42, and the cutting blade 44 is rotatably connected to the shell 42. The rotatable connection design between the cutting blade 44 and the shell 42 ensures the stability and safety of the cutting blade during high-speed rotation, while facilitating the cutting operation and improving the cutting efficiency and accuracy.

[0038] Furthermore, a laser rangefinder 5 is fixedly installed at the center of the top of the housing 42, and the output end of the laser rangefinder 5 is facing the light baffle 24. Through the installation of the laser rangefinder 5 and the design of its output end facing the light baffle 24, accurate measurement of the cutting length is achieved, replacing the traditional manual measurement method, simplifying the operation process, and improving the cutting accuracy and efficiency.

[0039] Furthermore, the distance between the laser rangefinder 5 and the light baffle 24 is equal to the distance between the cutting blade 44 and the light baffle 24. By designing the laser rangefinder 5 to be equidistant from the light baffle 24 and the cutting blade 44, the accuracy of the laser ranging is ensured to directly reflect the cutting position without the need for additional calculations, thereby improving the accuracy and efficiency of cutting.

[0040] When used specifically, the working principle of the utility model is as follows:

[0041] When using this doorframe cutting machine, the accuracy of the cut is ensured by precisely adjusting the relative position between the positioning mechanism 2 and the laser rangefinder 5, based on the desired length of the doorframe profile 34. This step is achieved by smoothly moving the slider 22 on the track 21. The movement of the slider 22 drives the synchronous movement of the column 23 and the light barrier 24 attached thereto. Ideal positioning is achieved when the laser beam emitted by the laser rangefinder 5 is blocked by the light barrier 24 and the distance displayed by the laser rangefinder 5 is exactly equal to the desired length of the doorframe profile 34 to be cut.

[0042] Subsequently, by rotating the positioning bolt 25, its lower end gradually comes into contact with the top of the track 21 until sufficient friction is achieved, thereby firmly fixing the slider 22 and the light baffle 24 thereon in the desired position. This design not only ensures accurate positioning but also greatly simplifies the traditional complex process of manual measurement and positioning, improving work efficiency.

[0043] After the light baffle 24 is positioned, the door frame profile 34 to be cut is placed between the two clamping plates 33 on the workbench 1. At this point, one end of the door frame profile 34 should be perpendicular and firmly against the light baffle 24 to ensure the correct starting point of the cut. The motorized telescopic rod 32 is then activated, moving the clamping plates 33 along a pre-set path until they firmly grip the sides of the door frame profile 34. This process not only stabilizes the position of the door frame profile 34 during cutting but also effectively prevents potential vibration and deviation during cutting, further enhancing cutting accuracy and safety.

[0044] Finally, when everything is ready, the cutting mechanism 4 begins its cutting task. The activation of the motor 43 drives the cutting blade 44 to rotate at high speed, generating a powerful cutting force. Because the distance between the laser rangefinder 5 and the cutting blade 44 is pre-set to be equal to the distance from the light barrier 24 to the cutting point, the cutting blade 44 can precisely cut the door frame profile 34 along the pre-set cutting line. This design ensures cutting accuracy and efficiency.

[0045] In summary, the door frame cutting machine realizes accurate and efficient cutting of door frame profiles through the coordinated action of the positioning mechanism 2, the clamping mechanism 3, the cutting mechanism 4 and the laser rangefinder 5, greatly improving the production efficiency and product quality of door frame processing.

[0046] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
