[0003] After searching the existing technology, Chinese patent CN215846104U was found to disclose a rapid chamfering device for rings. This patent features a feeding structure on a worktable, with a chamfering station on each side. Clamping structures on both sides of the chamfering station are used to clamp and position the rings, and a spindle machining structure is located above the chamfering station. However, during use, it was found that the feeding structure lacks a precise positioning mechanism, resulting in significant deviations in the workpiece feeding position. This affects the fit with the clamping structure, impacting processing quality and the continuous and stable operation of the equipment. Summary of the Invention

[0045] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0046] like Figure 1-4 As shown, an aluminum alloy chamfering device includes:

[0047] Frame 1, which is equipped with a mounting platform;

[0048] Conveyor belt device 2 is mounted on frame 1. Conveyor belt device 2 is provided with multiple workpiece positioning blocks 21 spaced apart along the conveying direction. Conveyor belt device 2 is provided with processing station.

[0049] A pair of clamping mechanisms 3 are provided on both sides of the conveyor belt device 2. The clamping mechanisms 3 are connected to clamping blocks 31, which are suitable for clamping the workpieces on the processing station of the conveyor belt device 2.

[0050] A lifting mechanism is installed on frame 1;

[0051] Main spindle assembly 5 is mounted on the lifting mechanism, and a chamfering milling cutter is mounted on the main spindle assembly 5;

[0052] The workpiece collection trough 6 is installed on the frame 1 and is located at the discharge end of the conveyor belt device 2.

[0053] The lifting mechanism is suitable for driving the spindle device 5 to move vertically, and the workpiece is suitable for being placed on the workpiece positioning block 21 of the conveyor belt device 2. Under the drive of the conveyor belt device 2, the workpiece moves to the processing station, and the lifting mechanism drives the spindle device 5 to the working position to perform chamfering on the workpiece.

[0054] In this embodiment, as Figure 1 and Figure 3 As shown, during operation, the workpiece is placed on the workpiece positioning block 21 of the conveyor belt device 2. After the conveyor belt device 2 drives the workpiece to the processing station, a pair of clamping mechanisms 3 on both sides of the conveyor belt device 2 simultaneously activate, clamping blocks 31 from both sides to hold the workpiece, ensuring its stable fixation at the processing station. The lifting mechanism drives the spindle device 5 to move vertically to the working position, and the chamfering milling cutter mounted on the spindle device 5 performs chamfering on the workpiece. After processing, the clamping mechanism 3 releases the clamping blocks 31, and the conveyor belt device 2 continues to drive the workpiece to the discharge end, where the chamfered workpiece is collected by the workpiece collection trough 6. The entire process solves the technical problem of inaccurate workpiece positioning leading to high clamping difficulty in the prior art, significantly improving the automation level and production efficiency of chamfering processing of aluminum alloy parts.

[0055] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a vertical support 12 is provided on the frame 1, and the vertical support 12 is vertically installed on the frame 1;

[0056] The lifting mechanism includes:

[0057] Two guide rails 41 are vertically mounted on the support frame 12;

[0058] Two sliders 42 are slidably mounted on corresponding guide rails 41;

[0059] Support plate 43 is fixedly mounted on slider 42, and main shaft device 5 is mounted on support plate 43;

[0060] The drive source 44 is mounted on the stand 12 and is connected to the slider 42 in a transmission manner. The drive source 44 is suitable for driving the slider 42 to move up and down along the guide rail 41.

[0061] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the guide rail 41 is fixed to the vertical surface of the stand 12 by mounting bolts. In some embodiments, the number of guide rails 41 is not limited to two and can be set according to specific needs. The slider 42 cooperates with the sliding groove of the guide rail 41, and the slider 42 can move linearly along the length of the guide rail 41. The support plate 43 is a rectangular plate structure, and the support plate 43 is fixed to the slider 42 by bolt connection. The main shaft device 5 is prior art and will not be described in detail in this embodiment.

[0062] The drive source 44 is a cylinder. The drive source 44 is connected to the support plate 43 through the telescopic end, thereby driving the support plate 43 and the main shaft device 5 to achieve vertical position adjustment.

[0063] Specifically, such as Figure 2-3 As shown, the aluminum alloy chamfering device also includes a chip cleaning mechanism, which includes:

[0064] Mounting block 71 is fixedly mounted on support plate 43. The mounting block 71 has a circular mounting groove inside, and a notch is provided on one side of the circular mounting groove. A through threaded hole is provided on the side wall corresponding to the notch.

[0065] The height adjustment cylinder 72 is adjustablely inserted into the circular mounting slot in the vertical direction. The height adjustment cylinder 72 is adapted to be locked in the circular mounting slot by a locking bolt passing through a threaded hole.

[0066] Air outlet 73 is installed at the lower end of height adjusting cylinder 72, and the air outlet of air outlet 73 faces the processing station.

[0067] In this embodiment, as Figure 2-3 As shown, the mounting block 71 is fixed to the edge of the support plate 43 by bolts. The circular mounting groove inside the mounting block 71 is a through-hole structure, with its axis set vertically. A notch extends from the side wall of the circular mounting groove to the outer surface of the mounting block 71, and the width of the notch is smaller than the diameter of the circular mounting groove. The axis of the threaded hole is perpendicular to the axis of the circular mounting groove, and the inner diameter of the threaded hole matches the thread specification of the locking bolt.

[0068] The height adjusting cylinder 72 has a cylindrical structure, and its outer diameter matches the inner diameter of the circular mounting groove. The height adjusting cylinder 72 can slide vertically within the circular mounting groove to adjust its position. After the height adjusting cylinder 72 is adjusted to the desired height, the locking bolt is screwed into the threaded hole, and the threaded connection of the locking bolt fixes the height adjusting cylinder 72 in the set position within the circular mounting groove. The height adjusting cylinder 72 has an internal gas channel that connects to an external gas source.

[0069] An air outlet 73 is installed at the lower opening of the height adjusting cylinder 72, with its outlet facing the workpiece surface that can be aligned with the machining station. An air source supplies air to the air outlet 73 through the gas channel within the height adjusting cylinder 72. The air outlet 73 then sprays compressed air to the machining station, blowing away metal chips generated during chamfering from the workpiece surface. The air pressure of the air outlet 73 is controlled within a small range to prevent airflow from causing workpiece displacement or affecting the stability of workpieces at other stations. The chip removal mechanism works in coordination with the clamping mechanism 3. When the clamping mechanism 3 holds the workpiece, the air outlet 73 directs airflow towards the machining area of ​​the clamped workpiece, ensuring targeted chip removal.

[0070] Specifically, such as Figure 1 As shown, the workpiece collection tank 6 is provided with multiple chip leakage holes.

[0071] In this embodiment, as Figure 1 As shown, the workpiece collecting groove 6 has a rectangular groove structure, and multiple chip-leaking holes are evenly distributed on the bottom and walls of the groove. The chip-leaking holes are circular through holes, and the diameter of the holes allows metal chips to pass through but prevents workpieces from falling out.

[0072] In addition, this embodiment also includes a chip collection trough (not shown in the figure). The chip collection trough is mounted on the frame 1, and its opening is aligned with the area below the workpiece collection trough 6. Metal chips that fall from the chip leakage hole fall directly into the chip collection trough for collection, achieving separation and collection of chips from finished workpieces.

[0073] Specifically, such as Figure 1 and Figure 3 As shown, the conveyor belt device 2 includes:

[0074] A rotary drive source is mounted on frame 1.

[0075] The drive roller is rotatably mounted on frame 1 and is connected to a rotary drive source.

[0076] Driven roller, the driven roller is rotatably mounted on frame 1, and the driven roller is spaced apart from the driving roller;

[0077] Multiple support rollers are arranged between the driving roller and the driven roller and are rotatably mounted on the frame 1;

[0078] Conveyor belt 26 is arranged around drive roller, driven roller and support roller. Rotary drive source is adapted to drive drive roller to rotate so as to drive conveyor belt 26 to run.

[0079] The workpiece positioning block 21 is disposed on the surface of the conveyor belt 26, and the workpiece positioning block 21 is adapted to limit the positional displacement of the workpiece during the conveying process.

[0080] Specifically, the rotational drive source is an electric motor.

[0081] In this embodiment, as Figure 1 and Figure 3 As shown, the motor is fixed to one side of the frame 1, and the motor is a servo motor. The drive roller is rotatably mounted on the frame 1 via a bearing housing, and the axis of the drive roller is parallel to the mounting platform of the frame 1. After the motor starts, it outputs torque to drive the drive roller to rotate. The driven roller has the same structure as the drive roller. The driven roller is rotatably mounted on the frame 1 via a bearing housing, and it rotates passively under the drive of the conveyor belt 26.

[0082] The support roller is positioned below the conveyor belt 26 between the drive roller and the driven roller, and is rotatably mounted on the frame 1 via a bearing housing. In some embodiments, the number of support rollers can be multiple, depending on the length of the conveyor belt 26 and the load-bearing requirements.

[0083] The workpiece positioning blocks 21 are fixed to the upper surface of the conveyor belt 26 by adhesive bonding. The workpiece positioning blocks 21 are spaced apart along the length of the conveyor belt 26, and the distance between adjacent workpiece positioning blocks 21 is determined according to the size of the workpiece. The height of the workpiece positioning blocks 21 is less than the thickness of the workpiece. The workpiece is placed on the surface of the conveyor belt 26 between adjacent workpiece positioning blocks 21. The workpiece positioning blocks 21 restrict the lateral movement of the workpiece perpendicular to the conveying direction during conveying and maintain the conveying interval.

[0084] Specifically, such as Figure 1 and Figure 3 As shown, the clamping mechanism 3 includes:

[0085] Linear guide rail, mounted on the frame, is located on one side of the conveyor belt device 2;

[0086] Guide slider, which is slidably mounted on the linear guide rail;

[0087] Telescopic drive source 33 is mounted on frame 1. Telescopic drive source 33 has a telescopic end, which is fixedly connected to guide slider. Telescopic drive source 33 is suitable for driving guide slider to move along linear guide rail.

[0088] The clamping block 31 is mounted on the guide slider, and the clamping block 31 is provided with a clamping groove corresponding to the workpiece.

[0089] In this embodiment, as Figure 1 and Figure 3 As shown, the length direction of the linear guide rail is parallel to the width direction of the conveyor belt device 2. The guide slider cooperates with the sliding groove of the linear guide rail, allowing the guide slider to perform linear reciprocating motion along the linear guide rail. The telescopic drive source 33 is a cylinder, with the cylinder body fixed on the frame 1. The telescopic end is connected to the guide slider via a connector. When the telescopic drive source 33 is activated, the telescopic end extends or retracts, driving the guide slider to move along the linear guide rail towards or away from the conveyor belt device 2.

[0090] The clamping block 31 is fixedly mounted on the guide slider by bolts. The clamping groove is located on the side of the clamping block 31 facing the conveyor belt device 2. The shape of the clamping groove matches the outline of the workpiece, and the depth of the clamping groove is less than the corresponding size of the workpiece. A pair of clamping mechanisms 3 arranged on both sides of the conveyor belt device 2 operate synchronously. The clamping grooves of the two clamping blocks 31 are arranged opposite to each other. When the telescopic drive source 33 drives the guide slider to move towards the conveyor belt device 2, the two clamping blocks 31 simultaneously contact the workpiece from both sides and clamp and fix the workpiece on the processing station.

[0091] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
