Description

Air cleaning structure for broaching machine Technical Field

[0001] This application relates to the field of broaching machine cleaning, and more specifically, to an air-blowing cleaning structure for broaching machines. Background Technology

[0002] A broaching machine uses a broach as a cutting tool to machine through holes, planes, or complex shaped surfaces of a workpiece through a linear broaching motion. Its key feature is that only the main motion (the broach's linear motion) is required, without any additional feed motion, because the feed is achieved by the broach's own structure (such as tooth rise).

[0003] After the broaching machine moves the broach to process the workpiece, debris will be present in both the broach groove and the guide groove where the broach is placed. The debris in the guide groove will affect the placement of the broach and the broaching machine's fixation of the broach. If the debris in the broach groove is not cleaned, it will cause the debris to scratch the workpiece. Therefore, workers usually use a brush to clean the broach groove and guide groove after the workpiece is processed. However, this cleaning takes too long and affects the processing efficiency.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Refer to Figure 1-5.

[0031] An air-blowing cleaning structure for a broaching machine includes: a broaching machine 1, a broach 2, a connecting pipe 3, an air-blowing component 4, and a pump body 5; the pump body 5 is a vane-type air compressor pump or a Roots vacuum pump. In this embodiment, a vane-type vacuum pump is preferred. The air-blowing component 4 is a dust-blowing gun. The broaching machine 1 forms a guide groove 11 for placing the broach 2 and a placement area for placing the workpiece; the broach 2 forms a cutting part for cutting the workpiece, the cutting part is a block structure, and the cutting part is integrally formed with the broach 2. A groove 21 is formed between the two cutting parts; the air-blowing component 4 is used to blow air to clean the guide groove 11 and the groove 21; the pump body 5 is connected to the air-blowing component 4 through the connecting pipe 3, and the pump body 5 is used to allow air to pass through the connecting pipe 3 and be discharged from the air-blowing component 4. The air blowing component 4 can clean the groove 21 and guide groove 11 of the broach 2, preventing debris from affecting the placement of the broach 2 and the fixation of the broach 2 by the broaching machine 1, and avoiding debris from scratching the workpiece. The air blowing component 4 cleans the debris in a short time, which can improve the processing efficiency of the workpiece.

[0032] Specifically, it also includes: a collection box 6 and a cooling pipe 7; the collection box 6 is a box structure with an open top. The cooling pipe 7 is installed on the broaching machine 1; the output end of the cooling pipe 7 faces the placement area; the cooling pipe 7 injects coolant into the position where the broach 2 contacts the workpiece through a coolant pump to prevent the temperature of the broach 2 from becoming too high when cutting the workpiece. The collection box 6 is located below the placement area. During the processing, the waste chips generated when the broach 2 cuts the workpiece can fall into the collection box 6, and the coolant poured on the broach 2 and the workpiece will also flow into the collection box 6 to avoid workshop contamination.

[0033] Specifically, the collection box 6 forms a waste debris collection chamber and a waste liquid collection chamber; a first filter screen 61 is installed between the waste debris collection chamber and the waste liquid collection chamber. The first filter screen 61 is installed to separate solid debris from the coolant, so as to facilitate subsequent separate processing (such as metal debris recovery and coolant recycling).

[0034] Specifically, the collection box 6 forms a first mounting groove 62; the opening direction of the first mounting groove 62 is parallel to the horizontal plane. The two ends of the first filter screen 61 form mounting portions 611 that match the shape of the mounting groove; the mounting portions 611 are block-shaped structures. The mounting portions 611 are slidably connected to the first mounting groove 62. The first filter screen 61 can be directly inserted into or removed from the collection box 6 through the first mounting groove 62, making operation simple.

[0035] Specifically, a waste liquid discharge port 9 is set at the end of the collection box 6 closest to the ground.

[0036] Specifically, a second mounting groove 63 is formed below the first mounting groove 62, and a second filter screen 64 is installed inside the second mounting groove 63. The filter holes on the first filter screen 61 are larger than those on the second filter screen 64. The first filter screen 61 is used to intercept some larger solid debris, while some smaller debris is intercepted by the second filter screen 64. Larger solid debris can be recycled, while smaller debris can be disposed of directly. A scraper 8 is installed inside the collection box 6; the scraper 8 forms a scraper section 81; the scraper section 81 is a plate-shaped structure made of silicone or plastic. The scraper 8 is fixed inside the collection box 6 with bolts. The scraper section 81 is in contact with the first filter screen 61; the extension direction of the scraper section 81 is perpendicular to the extension direction of the mounting groove. During use, the worker can first extract the coolant from the waste liquid collection chamber through the drain port, and then remove the second filter screen 64. Since there is a gap between the side of the second filter screen 64 facing the first filter screen 61 and the second mounting groove 63, some smaller debris on the second filter screen 64 will pass through the gap and be carried out by the second filter screen 64 when it is removed. After removing the second filter screen 64, the worker can remove the first filter screen 61. During removal, larger debris on the first filter screen 61 will be blocked by the scraper 81, causing the larger debris to fall into the waste liquid collection chamber. The worker can then recycle the larger debris in the collection box 6. In other embodiments, the bottom of the collection box 6 is also equipped with wheels to facilitate movement of the collection box 6.

[0037] Specifically, the first filter 61 forms a gripping part for hand holding.
