Description

Technical Field

[0001] This invention relates to the field of dust removal technology, specifically to a dust removal device for the surface treatment of a new energy vehicle frame. Background Technology

[0002] In the manufacturing and repair of new energy vehicle frames, surface treatment is a crucial process that directly affects the adhesion of subsequent coatings and the overall corrosion resistance of the frame. Common surface treatment methods include manual grinding and mechanical polishing. These operations generate a large amount of fine dust containing metal particles and abrasive debris. With increasingly stringent environmental regulations and heightened awareness of occupational health and safety, manufacturing companies have higher and higher requirements for dust control in grinding workshops. Effective dust removal can not only protect the respiratory health of workers but also prevent the risk of dust explosions, reduce dust pollution to the surrounding environment, and maintain workshop cleanliness. Therefore, dust removal technology for grinding stations has become an indispensable part of the new energy vehicle manufacturing process.

[0003] The conventional methods for dealing with dust generated by handheld grinding tools are as follows: First, a large-scale workshop-wide negative pressure dust removal system is used, which uses air vents on the walls or ceiling of the workshop to ventilate and remove dust from the entire space. However, this method consumes a lot of energy and has low efficiency in capturing dust generated at close range by the operator's hands, and the dust is easy to spread at the source. Second, an independent mobile industrial dust collector is used, which is connected to a dust hood through a hose. However, the dust hood needs to be fixed independently or supported by another hand, which greatly limits the flexibility of grinding operations. If the distance between the dust hood and the grinding wheel is too far, the suction power will be insufficient, and if it is too close, it will easily interfere with the grinding operation.

[0004] Existing technologies generally suffer from problems such as complex structure, high cost, and reduced operational flexibility of handheld grinding tools. Large systems consume a lot of energy, and fixed-point dust collection methods hinder operation. Adding protective covers increases the weight of the tools and reduces the convenience of operation, making it impossible to achieve efficient and timely dust removal at the source. Therefore, we need a dust removal device for the surface treatment of new energy vehicle frames. Summary of the Invention

[0014] Preferably, the central shaft end of the gear is fixedly connected to an air outlet pipe, and there are two gears, which are fixed at both ends of the air outlet pipe to drive the air outlet pipe to adjust its angle.

[0015] Preferably, a corrugated hose is fixedly connected to one side of the air outlet pipe, and the end of the corrugated hose away from the air outlet pipe is connected to the fan body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the scheme of this application:

[0018] 1. This new energy vehicle frame surface treatment dust removal device can efficiently absorb the high-frequency vibration generated when the main body of the fan is running at high speed by adding a shock-absorbing pad between the fan mounting frame and the wall. This significantly reduces the amplitude of vibration transmitted to the whole structure from the source, effectively reducing the noise generated during equipment operation, improving the workshop working environment, avoiding long-term high-decibel noise damage to the hearing of operators, and completely avoiding the loosening of various connecting parts caused by long-term high-frequency vibration. At the same time, the mounting frame is firmly fixed in the mounting groove of the wall with positioning bolts, ensuring the structural stability of the fan during long-term high-load operation.

[0019] 2. Through the linkage adjustment structure composed of a sliding movable plate, connecting rod, guide rod and support spring, the operator only needs to loosen the nut on the movable plate to flexibly adjust the opening distance between the two movable plates. It can adapt to the dust removal operation needs of new energy vehicle frames of different sizes and specifications. The adjusted baffle can form a semi-enclosed enclosure space in the grinding and dust removal area to prevent the discharged metal dust from rising and spreading over a large area. It allows most of the dust to fall naturally into the water pool below along the preset path, which greatly improves the dust collection efficiency and reduces the suspended residue of dust in the workshop air.

[0020] 3. This device relies on an electric push rod to drive the side plate seat, and through the meshing transmission of gears and a fixed gear ring, it drives the air outlet duct to complete multi-angle tilt adjustment. With the addition of a flexible corrugated hose that can be bent at will, the air outlet direction can be flexibly adjusted according to different positions of the frame grinding. It always ensures that the airflow is accurately directed to the recycling water pool below, which can directly guide the dust-laden airflow generated by grinding to the dust removal medium in the water pool, so that the dust can be fully captured and dissolved by the water, completely preventing the dust from escaping into the workshop environment, realizing a closed-loop dust removal operation without spillage, and improving the purification effect of the dust removal operation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a dust removal device for the surface treatment of new energy vehicle frames, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the system includes a wall 1. One side of the wall 1 is equipped with an operating platform 2 for supporting the frame of a vehicle to be dusted. The outer side of the wall 1 is fitted with a dust removal medium recovery and treatment water tank 4. A fan mounting assembly 3 is detachably mounted on the side wall of the wall 1. The fan mounting assembly 3 includes a mounting groove 301 pre-set in the side wall of the wall 1, and a mounting frame 302 is fitted and snapped into the mounting groove 301. A fan cover 304 is fixedly connected to one side of the mounting frame 302. A fan body 305 is disposed inside the mounting frame 302, and one side of the mounting frame 302 is fixed to the outer wall of the fan body 305. With shock-absorbing pads 306 connected, the mounting frame 302 is connected to the wall 1 via positioning bolts 303. When the fan body 305 starts to operate, it generates high-pressure airflow. The airflow is delivered to the air outlet 606 through the corrugated hose 607, creating a negative pressure in the grinding area. This causes the grinding dust to be sucked into the air outlet 606 and discharged. During the operation of the fan, the shock-absorbing pads 306 installed between the mounting frame 302 and the wall 1 can effectively absorb the high-frequency vibration generated by the fan body 305 during operation, reducing the operating noise of the equipment and avoiding the problem of loosening of connecting parts due to long-term vibration.

[0033] Further as Figure 3 , Figure 4 and Figure 5 As shown, the mounting frame 302 is detachable from the wall 1 by means of positioning bolts 303. One end of the positioning bolts 303 passes through the mounting frame 302 and is fastened in a reserved hole on one side of the wall 1. By setting the positioning bolts 303, it is easy to fix the mounting frame 302 to one side of the wall 1, which improves the stability of fixing the mounting frame 302 and facilitates the installation of the fan body 305.

[0034] Further as Figure 3 , Figure 4 and Figure 5 As shown, the mounting frame 302 forms a shock-absorbing structure with the wall 1 through the shock-absorbing pad 306, and the mounting frame 302 is fastened to the wall 1 by the shock-absorbing pad 306 to reduce the vibration generated by the fan body 305. By setting the shock-absorbing pad 306, the connection stability between the wall 1 and the mounting frame 302 is further improved when the mounting frame 302 is installed, the vibration generated by the fan body 305 is reduced, and the noise of the fan body 305 is reduced.

[0035] In a further preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, a baffle assembly 5 is installed inside the wall 1. The baffle assembly 5 includes a shielding plate 501, which is installed on the wall 1 by fixing bolts 502. By setting the fixing bolts 502, the connection stability between the shielding plate 501 and the wall 1 is further enhanced. The shielding plate 501 can block part of the dust blown out by the fan body 305, preventing it from rising and facilitating its fall into the water tank 4. By loosening the nuts on the moving plates 504, the moving plates 504 on both sides can be pulled at the same time. While the moving plates 504 slide along the moving groove 503, they will drive the sliding sleeve to slide along the guide rod 505 through the connecting rod 507, squeezing or stretching the support spring 506, thereby flexibly adjusting the unfolding distance of the two moving plates 504 to prevent dust from rising during the dust removal process.

[0036] Further as Figure 8 and Figure 9 As shown, the baffle plate 501 has a movable groove 503 inside, and a movable plate 504 is slidably connected inside the movable groove 503. There are two movable plates 504, and the two movable plates 504 are respectively inserted into the movable groove 503 from both ends of the baffle plate 501. By setting two movable plates 504 inside the baffle plate 501, the two movable plates 504 can slide along the movable groove 503, which facilitates the adjustment of the size of the baffle plate 501.

[0037] Further as Figure 8 and Figure 9 As shown, a guide rod 505 is fixedly connected inside the movable plate 504. A support spring 506 is sleeved on the outer wall of the guide rod 505. The end of the support spring 506 is provided with a sliding sleeve that matches the guide rod 505. A connecting rod 507 is hinged to one side of the sliding sleeve. A fixed seat 508 is hinged to the end of the connecting rod 507. There are four connecting rods 507, and the four connecting rods 507 are hinged around the fixed seat 508 to support the movable plates 504 on both sides. By setting four connecting rods 507 on the fixed seat 508, when the distance between the movable plates 504 on both sides is adjusted, the connecting rods 507 on both sides can be pulled, so that the connecting rods 507 can pull the sliding sleeve to slide along the outer wall of the guide rod 505. This causes the sliding sleeve to drive the support spring 506 to squeeze or stretch, which is used to adjust the distance between the two movable plates 504.

[0038] In a further preferred embodiment of the present invention, such as Figure 1 , Figure 6 and Figure 7As shown, the device also includes an adjustment assembly 6, which includes a fixed housing 601 fixed to one side of the wall 1. An electric push rod 602 is installed inside the fixed housing 601 and hinged to one side of the wall 1. A side plate seat 603 is fixedly connected to the end of the electric push rod 602. The electric push rod 602 is positioned between the wall 1 and the side plate seat 603, and is used to adjust the position of the side plate seat 603, thus enhancing the connection between the electric push rod 602 and the wall 1. 02 With the support of wall 1, the side plate seat 603 can be moved. The operator can start the electric push rod 602. The electric push rod 602 extends and retracts to move the side plate seat 603. The gear 604 in the side plate seat 603 rolls around the gear ring 605 fixed on the wall 1, and simultaneously drives the air outlet pipe 606 to complete the tilt adjustment at multiple angles. With the flexible corrugated hose 607, the air outlet direction can be adjusted as needed, so that the air outlet direction of the air outlet pipe 606 is towards the water tank 4.

[0039] Further as Figure 6 and Figure 7 As shown, a gear 604 is rotatably connected inside the side plate seat 603 via a bearing. A gear ring 605 is meshed with the outer wall of the gear 604. The gear ring 605 is fixed to one side of the wall 1. The gear 604 rotates along the gear ring 605 under the drive of the side plate seat 603. By setting the gear 604, when the gear 604 is pulled by the side plate seat 603, the gear 604 can roll along the gear ring 605, and at the same time drive the air outlet duct 606 to adjust the tilt angle.

[0040] Further as Figure 6 and Figure 7 As shown, an air outlet pipe 606 is fixedly connected to the end of the central shaft of the gear 604, and there are two gears 604. The two gears 604 are fixed at both ends of the air outlet pipe 606 and are used to drive the air outlet pipe 606 to adjust the angle. By setting gears 604 on both sides of the air outlet pipe 606, the stability of the air outlet pipe 606 during adjustment is improved.

[0041] Further as Figure 6 and Figure 7 As shown, a corrugated hose 607 is fixedly connected to one side of the air outlet duct 606, and the end of the corrugated hose 607 away from the air outlet duct 606 is connected to the fan body 305. By setting the corrugated hose 607, the air force delivered by the fan body 305 can be transported, and the direction of the air outlet duct 606 can be adjusted by bending angle.

[0042] Working principle: When the dust removal device for surface treatment of new energy vehicle frames is working, the new energy vehicle frame to be dusted is first placed stably on the operating table 2 to complete the positioning and fixation of the workpiece, which is ready for subsequent dust removal operations. After the device is started, the main body of the fan 305 starts to operate and generates directional blowing airflow. The airflow is delivered to the air outlet 606 through the corrugated hose 607 and sprayed out in a directional manner, directly blowing towards the grinding area of ​​the car frame on the operating table 2. This forces the dust generated during grinding to flow downward under the push of the directional airflow and the obstruction and guidance of the baffle plate 501, and finally flows into the dust removal medium recovery and treatment water pool 4 for collection.

[0043] During fan operation, the shock-absorbing pads 306 installed between the mounting frame 302 and the wall 1 effectively absorb the high-frequency vibrations generated by the fan body 305 during operation, reducing equipment operating noise and preventing loosening of connecting parts due to long-term vibration. Simultaneously, the positioning bolts 303 firmly secure the mounting frame 302 to the mounting groove 301 in the wall 1, ensuring the overall stability of the fan operation and facilitating subsequent fan disassembly and maintenance. During dust removal operations, loosening the nuts on the moving plates 504 simultaneously pulls both moving plates 504, causing them to slide along the moving groove 503. Simultaneously, the connecting rod 507 drives the sliding sleeve to slide along the guide rod 505, compressing or stretching the support spring 506, thereby flexibly adjusting the two moving plates 504. The spacing of 4 prevents dust from rising during dust removal and facilitates its fall into the water tank 4. During dust removal, the operator can activate the electric push rod 602. The electric push rod 602 extends and retracts, causing the side plate seat 603 to move. The gear 604 inside the side plate seat 603 rolls circumferentially along the gear ring 605 fixed on the wall 1, simultaneously driving the air outlet duct 606 to complete multi-angle tilt adjustment. With the flexible corrugated hose 607, which can be bent at will, the air outlet direction can be adjusted as needed, so that the air outlet direction of the air outlet duct 606 is towards the water tank 4. With the dust blocked by the baffle plate 501, it will not rise and spread over a large area, but will fall naturally along the preset path and finally flow into the dust removal medium recovery and treatment water tank 4 on the outside with the airflow, completing the dust collection and recovery.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
