Detailed Implementation

[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0024] like Figures 1 to 4 As shown, this embodiment designs a lateral blind hole blowing device for a workpiece, including a mounting platform 4, a blowing unit 5, a support frame 1, a slag guide hopper 3, a shield 6, a slag collection box 2, and other components.

[0025] The support frame 1 adopts a frame structure, and the mounting platform 4 is installed on the top of the support frame 1.

[0026] The mounting platform 4 can be a frame structure or a platform structure. Placement stations are provided on the mounting platform 4. There can be one or more placement stations. When there are multiple placement stations, they are arranged in a rectangular array. When there is only one placement station, it is located at the center of the mounting platform 4. Each placement station is used to place one workpiece 7. The workpiece 7 can be picked up and placed by a robotic arm, thereby improving the level of automation.

[0027] Several blowing units 5 are installed around the placement station; each blowing unit 5 corresponds one-to-one with a lateral blind hole on the workpiece 7. Each blowing unit 5 can blow one lateral blind hole.

[0028] The purging unit 5 includes components such as a first telescopic cylinder 51, a second telescopic cylinder 57, an alignment cone 54, and an air blowing pipe 56. The air blowing pipe 56 is fixedly connected to the telescopic end of the first telescopic cylinder 51 and can extend into the lateral blind hole for purging. The alignment cone 54 is fixedly connected to the telescopic end of the second telescopic cylinder 57 and can abut against the edge of the lateral blind hole to align it. The air blowing pipe 56 passes through the central hole of the alignment cone 54, and the two can move relative to each other.

[0029] The first telescopic cylinder 51 has a first telescopic platform 52 at its telescopic end, and a blowpipe seat 58 is fixed on the first telescopic platform 52; the air blowing pipe 56 is fixedly connected to the blowpipe seat 58. The first telescopic platform 52 may be L-shaped, with its lateral portion extending above the first telescopic cylinder 51. The second telescopic cylinder 57 is fixedly connected to the first telescopic platform 52. The second telescopic cylinder 57 has a second telescopic platform 55 fixed at its telescopic end, and the alignment cone 54 is fixed on the second telescopic platform 55; a guide rod 53 is connected to the second telescopic platform 55, and the guide rod 53 is slidably connected to the blowpipe seat 58; a spring is sleeved on the guide rod 53, and the two ends of the spring are respectively used to abut against the blowpipe seat 58 and the second telescopic platform 55.

[0030] When the purging unit 5 is working: First, the second telescopic cylinder 57 extends, causing the alignment cone 54 to abut against the edge of the lateral blind hole. The conical surface of the alignment cone 54 can fit the lateral blind hole to align the workpiece 7, ensuring that the air blowing pipe 56 is directly opposite the lateral blind hole. After the alignment is completed, the second telescopic cylinder 57 retracts, and the alignment cone 54 moves away from the lateral blind hole. Then, the first telescopic cylinder 51 extends, allowing the purging pipe to pass through the alignment cone 54 and be inserted into the lateral blind hole. When the purging pipe is ventilated, the airflow from the purging pipe can purify the waste residue in the lateral blind hole, allowing the waste residue to be blown out of the lateral blind hole along the gap between the purging pipe and the lateral blind hole.

[0031] The mounting platform 4 is equipped with lateral stops 41 and support blocks 42, which cooperate to support and limit the workpiece 7 on the mounting platform 4. The support blocks 42 vertically support the workpiece 7, and the lateral stops 41 limit the sides of the workpiece 7. There are at least two lateral stops 41. When the workpiece 7 is placed on the placement station, the two lateral stops 41 cooperate to block the opposite sides of the workpiece 7, thereby limiting the horizontal swaying of the workpiece 7. The lateral stops 41 can be L-shaped and are fixed to the mounting platform 4 with screws. There are multiple support blocks 42, each supporting different parts of the workpiece 7.

[0032] Below the mounting platform 4 is a slag guide hopper 3, and several slag leakage holes are distributed on the mounting platform 4. A slag collection box 2 is placed at the outlet of the slag guide hopper 3. The residue blown out from the side blind hole can fall into the slag collection box 2 through the slag leakage holes and the slag guide hopper 3, so as to facilitate the collection of the slag collection box 2.

[0033] A shield 6 is provided above the mounting platform 4. A workpiece loading / unloading port 61, matching the shape of the workpiece 7, is located at the center of the shield 6, allowing the workpiece 7 to be placed onto the placement station through this port 61. The shield 6 is installed above the purging unit 5 to prevent waste from the lateral blind holes from splashing upwards, reducing the probability of waste splashing into the workers' eyes or respiratory tract. Multiple vertical support members 43 are installed on the mounting platform 4, with their upper ends connected to the shield 6 to support it.

[0034] The workpiece 7 can be triangular star-shaped, such as... Figure 1 As shown, it can also be other shapes. When the shape of the workpiece 7 is different, the arrangement of the purging unit 5 is also different. The lateral blind holes are located on the end faces of the three ends of the workpiece 7, and each lateral blind hole is directly opposite a purging unit 5.

[0035] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
