Description

Technical Field

[0001] This utility model relates to the field of automotive door hinge production technology, specifically to a waste chip collection and cleaning mechanism for a sawing and milling composite machine used in automotive door hinge production. Background Technology

[0002] As a key automotive component, door hinges require high-precision machining using a sawing and milling machine. This machine combines sawing and milling functions, enabling efficient machining of complex shapes. However, it generates a large amount of metal shavings during processing. Furthermore, cooling the sawing and milling cutters causes coolant to splash everywhere along with the metal shavings.

[0003] If coolant and metal shavings are not cleaned up in time, they will spill onto the equipment and workshop floor, causing shavings to accumulate. This can jam mechanical parts, leading to decreased equipment precision or shutdown. Metal particles and coolant residue in the shavings can pollute the workshop environment and endanger the health of operators. Current cleaning methods mostly rely on manual cleaning at regular intervals, combined with a negative pressure dust collection system to collect some metal shavings. However, this method depends on operators cleaning regularly, and for safety reasons, the machine needs to be shut down, resulting in reduced production efficiency. The negative pressure dust collection system has weak adsorption capacity for large metal fragments and is prone to clogging pipes. Utility Model Content

[0004] The purpose of this invention is to provide a waste chip collection and cleaning mechanism for a sawing and milling composite machine used in the production of car door hinges, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste collection and cleaning mechanism for a sawing and milling composite machine used in the production of car door hinges, comprising two mounting seats, a sawing and milling part of the sawing and milling composite machine fixed above the mounting seats, a protective component provided on the sawing and milling part of the sawing and milling composite machine, a collection mechanism provided between the two mounting seats, the collection mechanism comprising a liquid storage tank, a clamping part of the sawing and milling composite machine provided above the liquid storage tank, a cleaning mechanism provided inside the liquid storage tank, the cleaning mechanism comprising a scraping motor, a bidirectional screw and two limiting rods, the two limiting rods fixed inside the liquid storage tank, the bidirectional screw rotatably disposed inside the liquid storage tank, two mounting plates slidably disposed on the two limiting rods, both mounting plates being threadedly connected to the bidirectional screw, the bidirectional screw being located between the two limiting rods, the scraping motor fixed on the liquid storage tank, and the output shaft of the scraping motor being fixedly connected to the bidirectional screw.

[0006] The liquid storage tank is fixed between two mounting bases. Inside the liquid storage tank, there are two support rods. A collection box is slidably installed inside the liquid storage tank. The collection box is located on the two support rods. Inside the collection box, from top to bottom, there are stainless steel filter screens and non-woven fabric filter screens.

[0007] With the above structure, coolant and metal debris fall into the collection box, where stainless steel and non-woven fabric filters filter the coolant and trap the metal debris.

[0008] Two guide boxes are fixed on both sides of the liquid storage tank, and two liquid inlets are opened on both sides of the liquid storage tank. The liquid inlets are located at the bottom of the guide boxes.

[0009] With the above structure, coolant and metal debris splashed onto the protective components fall into the interior of the guide box, and then slide through the inlet into the interior of the collection box.

[0010] The liquid storage tank has a discharge hole, two arc-shaped grooves and two sliding grooves on the top. The arc-shaped grooves are connected to the corresponding sliding grooves and discharge holes. The discharge hole is located at the lowest point of the arc-shaped groove, and the sliding groove is located at the center of the arc-shaped groove.

[0011] With the above structure, the arc-shaped groove facilitates the sliding of coolant and metal debris, the discharge hole facilitates the sliding of coolant and metal debris into the inside of the collection box, and the sliding groove facilitates the movement of the cleaning mechanism.

[0012] The cleaning mechanism also includes several spring telescopic rods, which are fixed on mounting plates at corresponding positions. The spring telescopic rods are slidably disposed inside the sliding grooves, and a scraper is fixed above the spring telescopic rods. The scraper is slidably disposed inside the arc-shaped grooves.

[0013] With the above structure, the moving mounting plate drives the moving spring telescopic rod, which in turn drives the scraper to move inside the arc-shaped groove. The scraper scrapes and cleans the metal debris inside the arc-shaped groove. At the same time, the spring telescopic rod elastically contracts, continuously applying force to the scraper, so that the scraper remains in contact with the arc-shaped groove.

[0014] The protective assembly includes two guard plates 1 and two guard plates 2. The two guard plates 1 are fixed on the sawing and milling part of the sawing and milling machine on one side, and the two guard plates 2 are fixed on the sawing and milling part of the sawing and milling machine on the other side. The guard plates 1 and guard plates 2 are staggered, and both guard plates 1 and guard plates 2 are provided with anti-collision holes.

[0015] With the above structure, the coolant and metal chips splashed onto guard plate one and guard plate two during the sawing and milling process of the sawing and milling combined machine. Guard plate one and guard plate two block the coolant and metal chips, and the blocked coolant and metal chips fall into the interior of the guide box.

[0016] Compared with the prior art, the beneficial effects of this utility model are: A waste chip collection and cleaning mechanism for a sawing and milling composite machine used in the production of car door hinges uses a spring telescopic rod and a scraper to scrape and clean the metal chips inside the arc-shaped groove, preventing the accumulation of metal chips. At the same time, after collecting enough metal chips, the collection box can be pulled out to clean the metal chips inside the collection box without stopping the machine, thus improving production efficiency.

[0020] like Figures 1-3As shown, this utility model provides a technical solution: a waste collection and cleaning mechanism for a sawing and milling composite machine used in the production of car door hinges, including two mounting bases 2. The sawing and milling part 1 of the sawing and milling composite machine is fixed above the mounting bases 2. A protective component is provided on the sawing and milling part 1 of the sawing and milling composite machine. A collection mechanism is provided between the two mounting bases 2. The collection mechanism includes a liquid storage tank 3. A clamping part 8 of the sawing and milling composite machine is provided above the liquid storage tank 3. A cleaning mechanism is provided inside the liquid storage tank 3. The cleaning mechanism includes a scraping motor 10, a bidirectional screw 15, and two limiting rods 14. The two limiting rods 14 are fixed inside the liquid storage tank 3. The bidirectional screw 15 is rotatably disposed inside the liquid storage tank 3. Two mounting plates 21 are slidably disposed on the two limiting rods 14. Both mounting plates 21 are threadedly connected to the bidirectional screw 15. The bidirectional screw 15 is located between the two limiting rods 14. The scraping motor 10 is fixed on the liquid storage tank 3. The output shaft of the scraping motor 10 is fixedly connected to the bidirectional screw 15.

[0021] The liquid storage tank 3 is fixed between two mounting bases 2. Two support rods 18 are fixed inside the liquid storage tank 3. A collection box 4 is slidably installed inside the liquid storage tank 3. The collection box 4 is located on the two support rods 18. A stainless steel filter screen 17 and a non-woven fabric filter screen 16 are arranged sequentially from top to bottom inside the collection box 4. Coolant and metal debris fall into the collection box 4. The stainless steel filter screen 17 and the non-woven fabric filter screen 16 filter the coolant in sequence and trap the metal debris.

[0022] Two guide boxes 5 are fixed on both sides of the liquid storage tank 3. Two liquid inlets 7 are opened on both sides of the liquid storage tank 3. The liquid inlets 7 are located at the bottom of the guide boxes 5. The coolant and metal debris splashed onto the protective components fall into the interior of the guide boxes 5. The coolant and metal debris slide into the interior of the collection box 4 through the liquid inlets 7.

[0023] The liquid storage tank 3 has a discharge hole 11, two arc-shaped grooves 9 and two sliding grooves 12 on its upper part. The arc-shaped grooves 9 are connected to the corresponding sliding grooves 12 and discharge holes 11. The discharge hole 11 is located at the lowest point of the arc-shaped groove 9 and the sliding groove 12 is located at the center of the arc-shaped groove 9. The arc-shaped grooves 9 facilitate the sliding of coolant and metal debris, the discharge holes 11 facilitate the sliding of coolant and metal debris into the interior of the collection box 4, and the sliding grooves 12 facilitate the movement of the cleaning mechanism.

[0024] The cleaning mechanism also includes several spring telescopic rods 19, each fixed to a mounting plate 21 at a corresponding position. The spring telescopic rods 19 are slidably disposed inside the sliding groove 12. A scraper 13 is fixed above the spring telescopic rods 19 and is slidably disposed inside the arc-shaped groove 9. The movement of the mounting plate 21 causes the spring telescopic rods 19 to move, and the spring telescopic rods 19 cause the scraper 13 to move inside the arc-shaped groove 9. The scraper 13 scrapes and cleans the metal debris inside the arc-shaped groove 9. At the same time, the spring telescopic rods 19 elastically contract, continuously applying force to the scraper 13, so that the scraper 13 continuously adheres to the arc-shaped groove 9.

[0025] The protective assembly includes two guard plates 6 and two guard plates 20. The two guard plates 6 are fixed to the sawing and milling part 1 on one side of the sawing and milling compound machine, and the two guard plates 20 are fixed to the sawing and milling part 1 on the other side of the sawing and milling compound machine. The guard plates 6 and 20 are staggered, and both guard plates 6 and 20 are provided with anti-collision holes. When the sawing and milling part 1 of the sawing and milling compound machine is grinding, the coolant and metal debris splash onto the guard plates 6 and 20. The guard plates 6 and 20 block the coolant and metal debris, and the blocked coolant and metal debris fall into the interior of the guide box 5.

[0026] Working principle: The door hinge to be processed is placed on the clamping part 8 of the sawing and milling composite machine. The clamping part 8 clamps and locks the door hinge. The sawing and milling part 1 of the sawing and milling composite machine processes the door hinge. At the same time, coolant is injected to cool the cutting tool. During the production process, the cutting tool rotates, throwing out coolant and metal chips. Most of the coolant and metal chips fall into the arc-shaped groove 9. The scraping motor 10 drives the bidirectional screw 15 to rotate through the output shaft. The bidirectional screw 15 drives the two mounting plates 21 to move synchronously in opposite directions. The two mounting plates 21 drive the spring telescopic rod 19 to move. The spring telescopic rod 19 drives the scraper 13 to move inside the arc-shaped groove 9. The scraper 13 scrapes and cleans the metal chips inside the arc-shaped groove 9, making the metal... Debris falls into the collection box 4. A small amount of coolant and metal debris splashes onto the first guard plate 6 and the second guard plate 20. The first guard plate 6 and the second guard plate 20 block the coolant and metal debris. After being blocked, the coolant and metal debris fall into the guide box 5. The coolant and metal debris slide through the inlet 7 into the collection box 4. The stainless steel filter screen 17 and the non-woven fabric filter screen 16 filter the coolant in sequence and intercept the metal debris. After collecting enough metal debris, the collection box 4 can be removed and the metal debris inside the collection box 4 can be cleaned without stopping the machine, which improves production efficiency.
