Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy pipe processing equipment, and in particular to a cutting device for aluminum alloy pipes. Background Technology

[0002] Metal cutting is a process of interaction between the workpiece and the cutting tool. The tool removes excess metal from the workpiece and, while controlling productivity and cost, ensures the workpiece achieves the geometric accuracy, dimensional accuracy, and surface quality required by design and process specifications. To achieve this, there must be relative movement between the workpiece and the cutting tool, i.e., cutting motion. In the production and processing of aluminum alloy tubes, cutting is necessary to obtain specific shapes and dimensions.

[0003] Chinese Utility Model Patent No. CN202323353592.9 discloses a metal pipe cutting mechanism. It includes a base plate and a movable stage, the movable stage being rotatably connected to the base plate. A rotating shaft is fixed to the output end of a motor. A groove is formed on the top surface of the base plate below the rotating shaft, and a slider is disposed inside the groove. A motor is fixed to the top surface of the slider, and a chuck is fixed to the output end of the motor. Several rotating shafts are fixedly spaced inside the chuck, each rotating shaft being rotatably connected to the inner wall of the chuck. Each rotating shaft is threadedly connected to a jaw. This utility model uses adjustable jaws to engage the metal pipe on the chuck, allowing the metal pipe to contact the cutting blade while rotating. This results in a smooth cross-section of the cut metal pipe, facilitating rapid cutting by workers, reducing blade wear, and improving production efficiency.

[0004] However, in the aforementioned existing technology, only one end of the pipe to be processed is fixed by a chuck and rotated under the drive of a motor. If the length of the pipe is long, fixing only one end makes the stability of the pipe weak, and the other end, which is not fixed and supported, is prone to tilting and displacement. Therefore, optimization and improvement are needed to solve this problem. Utility Model Content

[0025] Example 1

[0026] As shown in the figure, the fixing mechanism for fixing the aluminum alloy tube groove to be processed consists of a main fixing frame 21, a rotary motor 23, a secondary fixing frame 22, and a fixing chuck. The main fixing frame 21 is fixed on the operating table 1, and the secondary fixing frame 22 is located opposite to the main fixing frame 21 and is installed on an adjustable mechanism. The fixing chuck is connected to the main fixing frame 21 and the secondary fixing frame 22 through connecting shafts. The connecting shaft on the main fixing frame 21 that is connected to the fixing chuck is connected to the output end of the rotary motor 23, thereby realizing the rotation of the fixing chuck controlled by the rotary motor 23.

[0027] like Figure 5 The fixed chuck includes a fixed plate 241, an adjusting screw 242, and a locking block 243. The fixed plate 241 has four sets of adjusting grooves in a cross shape. The adjusting screw 242 is installed in each adjusting groove through a bearing. One end of the locking block 243 extends into the adjusting groove and is threaded to the adjusting screw 242. The upper end of the locking block 243 is set with an arc-shaped structure and an anti-slip pad is provided on the surface. By rotating the adjusting screw 242, the position of each locking block 243 is adjusted so that the four sets of locking blocks 243 abut against the outer wall of the pipe, thereby limiting and fixing the pipe.

[0028] like Figure 3An adjustment mechanism is used to adjust the position of the auxiliary fixing frame 22. The two ends of the lead screw 42 in the adjustment mechanism are respectively installed between two fixing blocks 44 through bearings. The two fixing blocks 44 are respectively set on both sides of the slot opening of the moving slot 11 below the operating table 1. One end of the lead screw 42 is connected to the handle 41. The moving block 43 is threadedly connected to the lead screw 42. The upper end of the moving block 44 passes through the moving slot and extends out to connect with the bottom of the auxiliary fixing frame 22.

[0029] like Figure 1 and 2 A cutting assembly is installed on the operating table 1 next to the fixed mechanism. The cutting assembly consists of a mounting box 31, a telescopic cylinder 32, a mounting bracket 33, a motor 34, and a cutting blade 35. Figure 4 The mounting box 31 contains a telescopic cylinder 32. The telescopic end of the telescopic cylinder 32 is connected to the mounting frame 33. The mounting frame 33 is equipped with a motor 34 for driving the cutting blade 35. The output end of the motor 34 is connected to the cutting blade 35.

[0030] The cutting assembly is mounted on an axial drive mechanism that controls its reciprocating axial movement, and this axial drive mechanism is fixed to the operating table, such as... Figure 2 The rear side of the mounting box 31 is fixedly connected to the movable seat 54 in the axial drive mechanism by bolts. The screw 53 is installed in the groove provided on the fixed seat 51 in the axial drive mechanism by bearing. One end of the screw 53 is connected to the output end of the drive motor 52. One end of the movable seat 54 extends into the groove and is threadedly connected to the screw 53.

[0031] To facilitate better axial movement of the mounting box 31, a slider 61 is provided at the bottom of the mounting box 31. The slider 61 is adapted to be mounted on the slide rail 62 and is slidably connected to the slide rail 62. The slide rail 62 is fixed to the mounting base 51 by screws.

[0032] Example 2

[0033] During processing, this utility model first fixes one end of the aluminum alloy tube by means of the fixing chuck on the main fixing frame 21, and then fixes the other end of the aluminum alloy tube by means of the fixing chuck on the auxiliary fixing frame 22. Compared with the current method of fixing only one end, fixing both ends enhances the stability of the aluminum alloy tube.

[0034] Furthermore, before using the secondary fixing bracket 22 to fix the other end of the pipe, the screw 42 can be rotated by operating the handle 41 in the adjustment mechanism, which will drive the moving block 43 to move axially. The movement of the moving block 43 will drive the secondary fixing bracket 22 to move, thereby adjusting the position of the secondary fixing bracket 22 and adjusting the distance between the main fixing bracket 21 and the secondary fixing bracket 22. This will satisfy the need to fix aluminum alloy pipes of different lengths and enhance practicality.

[0035] After the pipe is fixed, the telescopic cylinder 32 of the cutting assembly is activated to adjust the contact between the cutting blade 35 and the outer wall of the pipe. Then, the motor that drives the cutting blade 35 and the drive motor 51 that realizes axial movement are started to cut the pipe.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
