Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, specifically relating to an aluminum profile that is easy to position and machine using CNC. Background Technology

[0002] Aluminum profiles are widely used in the manufacture of frame structures for automated equipment, robots, and precision instruments due to their advantages such as light weight, high strength, and ease of processing. Currently, during CNC machining, operators typically use the T-slots or surfaces of the aluminum profiles as a rough positioning reference. However, because the T-slots of standard aluminum profiles have large dimensional tolerances and may have scratches or slight deformations on the surface, directly using them as a reference leads to low positioning accuracy and poor repeatability. Therefore, there is a need for an aluminum profile that is easy to position during CNC machining.

[0003] Problems with existing technology: In current technology, standard aluminum profiles are usually positioned directly on the surface of the profile during CNC machining. However, this positioning method is not precise enough and clamping and alignment are time-consuming and labor-intensive. In addition, aluminum profiles will undergo thermal deformation during long-term processing, which will cause the positioning structure to easily shift, affecting the consistency of batch processing. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum profile that is easy to position during CNC machining. The positioning base, which is integrally extruded with the aluminum profile body, can provide vertical and horizontal positioning references for the CNC positioning structure. At the same time, through the linkage of heat dissipation channels, connecting pipes, and circulating coolant equipment, thermal deformation of the aluminum profile can be avoided.

[0005] The specific technical solution adopted by this utility model is as follows: An aluminum profile that is easy to position and machine using CNC machining includes an aluminum profile body, wherein a T-shaped groove is formed on the surface of the aluminum profile body; The aluminum profile body has positioning bases at both ends and heat dissipation channels inside. A vertical reference surface is provided at the angle between the T-shaped slide and the aluminum profile body, and a horizontal reference surface is provided at the top of the T-shaped slide. The vertical and horizontal reference surfaces are used to calibrate the CNC machining positioning structure.

[0006] The positioning base and the T-shaped groove are integrally extruded, and the surfaces of the vertical reference surface and the horizontal reference surface are both anodized.

[0007] The vertical reference plane and the horizontal reference plane are perpendicular to each other, and both have undergone precision machining.

[0008] The positioning base has a right-angled trapezoidal cross section, and the inclined surface of the positioning base has a through groove, and the through groove inside the positioning base has a through slot.

[0009] The positioning base also includes a quick-release reference base that is slidably installed inside the mounting groove; The quick-release reference base includes a screw and an adjusting sleeve. The screw is threadedly installed on the outside of the positioning reference block. The adjusting sleeve is used to drive the screw to rotate, so that the positioning reference block moves vertically inside the mounting groove.

[0010] Multiple heat dissipation channels are provided, and the direction in which the multiple heat dissipation channels penetrate the aluminum profile body is the same as that of the T-shaped groove.

[0011] Both ends of the heat dissipation channel are connected to connecting pipes via threaded interfaces. The connecting pipes consist of multiple U-shaped pipes and straight pipes.

[0012] The technical effects achieved by this utility model are as follows: This invention features a positioning base integrally formed on both sides of an aluminum profile body. A vertical reference surface is provided at the angle between the positioning base and the aluminum profile body, and a horizontal reference surface is vertically provided at the top of the vertical reference surface. The vertical and horizontal reference surfaces provide a positioning reference for the CNC positioning structure, thereby facilitating the calibration of the positioning structure. In addition, since the positioning base also has a quick-release reference base that is easy to adjust and replace, the calibration range of the positioning structure is further improved, and the CNC machining accuracy is also improved.

[0013] This invention utilizes multiple heat dissipation channels opened inside the aluminum profile body, which are connected together by multiple U-shaped connecting pipes. At the same time, a straight connecting pipe for water inlet and outlet is installed on the end face of the heat dissipation channel on the same side of the aluminum profile body. By linking the straight connecting pipe with the circulating coolant equipment, the thermal deformation of the aluminum profile caused by frictional heat and changes in ambient temperature can be effectively suppressed, thus fundamentally ensuring the dimensional stability of the aluminum profile during long-term processing and mass production.

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-5 As shown, an aluminum profile that is easy to position and machine using CNC includes an aluminum profile body 1, and a T-shaped groove 2 is formed on the surface of the aluminum profile body 1. Positioning bases 4 are provided at both ends of the aluminum profile body 1, and heat dissipation channels 5 are provided inside the aluminum profile body 1. A vertical reference surface 41 is provided at the angle between the T-shaped slide 2 and the aluminum profile body 1, and a horizontal reference surface 42 is provided at the top of the T-shaped slide 2. The vertical reference surface 41 and the horizontal reference surface 42 are used to calibrate the CNC machining positioning structure.

[0018] See attached document Figures 1 to 4 In this embodiment, the positioning base 4 and the T-shaped groove 2 are integrally extruded, and the surfaces of the vertical reference surface 41 and the horizontal reference surface 42 are both anodized.

[0019] In the above embodiments, since the surfaces of the vertical reference surface 41 and the horizontal reference surface 42 are specially treated to have excellent corrosion resistance, high hardness and wear resistance, the corrosion of the vertical reference surface 41 and the horizontal reference surface 42 is avoided from affecting the calibration accuracy.

[0020] Furthermore, the vertical reference surface 41 and the horizontal reference surface 42 are perpendicular to each other, and are precision machined to form high-precision vertical reference surface 41 and horizontal reference surface 42. The perpendicularity tolerance of the vertical reference surface 41 and the horizontal reference surface 42 is less than 0.05 mm, and the surface roughness of the vertical reference surface 41 and the horizontal reference surface 42 is not greater than 1.6 μm.

[0021] In addition, multiple through-holes are machined on the surface of the aluminum profile body 1 near the positioning base 4 as process positioning holes. The axis of the process positioning hole maintains a fixed parallel distance with the vertical reference plane 41 and a fixed vertical distance with the horizontal reference plane 42. These holes can also serve as auxiliary references. When using a specific fixture, the initial positioning of the profile can be achieved by inserting a positioning pin.

[0022] It should be noted that the cross-section of the positioning base 4 is a right trapezoid, and the inclined surface of the positioning base 4 is provided with a through groove. Furthermore, the through groove inside the positioning base 4 is provided with a through groove 44. Therefore, the bolt can pass through the positioning base 4 through the waist-shaped through groove 44, and the aluminum profile body 1 and the positioning base 4 can be installed and fixed to the CNC equipment. At the same time, since the through groove 44 is a countersunk hole design, the aesthetics are further improved.

[0023] Please refer to the appendix again. Figure 2 , Figure 3 and Figure 4 It is worth noting that the positioning base 4 also includes a quick-release reference base 43 that is slidably installed inside the mounting groove. The quick-release reference base 43 includes a screw 432 and an adjusting sleeve 433 that are rotatably installed inside the positioning base 4. The screw 432 is threadedly installed on the outside of the positioning reference block 431. At the same time, the adjusting sleeve 433 is used to drive the screw 432 to rotate, so that the positioning reference block 431 moves vertically inside the mounting groove. Therefore, by conveniently replacing the positioning reference block 431, the range of CNC positioning structure calibration is further expanded.

[0024] See attached document Figure 1 and Figure 5 In addition, multiple heat dissipation channels 5 are provided, and multiple heat dissipation channels 5 penetrate through the aluminum profile body 1. The penetration direction of the heat dissipation channels 5 is the same as that of the T-shaped groove 2. Both ends of the heat dissipation channels 5 are connected to the connecting pipes 3 through threaded interfaces. The connecting pipes 3 are composed of multiple U-shaped pipes and straight pipes. Multiple U-shaped connecting pipes 3 can connect multiple heat dissipation channels 5 together. The end face of the heat dissipation channel 5 located on the same side of the aluminum profile body 1 is connected to the circulating coolant equipment through the straight connecting pipes 3, so that the coolant circulates in the heat dissipation channels 5 inside the aluminum profile body 1, avoiding high temperature thermal deformation of the aluminum profile body 1.

[0025] The working principle of this utility model is as follows: By setting a vertical reference surface 41 and a horizontal reference surface 42 that are perpendicular to each other on the surface of the positioning base 4, a reference surface can be provided for the calibration of the CNC positioning structure, thereby improving the positioning accuracy of the workpiece. At the same time, a positioning reference block 431 that can be lifted and disassembled is also set inside the positioning base 4, so the calibration range can be further improved. By opening multiple heat dissipation channels 5 inside the aluminum profile body 1, and the multiple heat dissipation channels 5 are connected by U-shaped connecting pipes 3, and the heat dissipation channels 5 are also connected to the coolant circulation equipment through straight connecting pipes 3, the coolant can circulate inside the aluminum profile body 1 to carry away the high temperature generated during processing, and avoid the aluminum profile body 1 from high temperature thermal deformation, which would cause the CNC positioning structure to shift due to the thermal deformation of the aluminum profile body 1 and affect the processing accuracy.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
