Description

Technical Field

[0001] This application belongs to the field of turning technology, specifically relating to a hole machining device for an automobile suspension frame. Background Technology

[0002] In the automotive manufacturing industry, the automotive suspension frame is one of the key components of a car, and its machining precision directly affects the vehicle's driving stability, comfort, and safety. The automotive suspension frame typically has multiple holes, which need to meet strict requirements for positional accuracy and concentricity to ensure precise assembly with other automotive parts.

[0003] In related technologies, chips are generated during the turning process of holes in automotive mounting frames. Traditional chip removal methods have a limited cleaning range and cannot flexibly adjust the cleaning position as the automotive mounting frame rotates. They are also unable to thoroughly clean complex areas such as the frame interior and hole walls, leading to the accumulation of chips and residues in these areas. This affects the surface finish of the hole walls, reduces the machining accuracy of the automotive mounting frame, and may even cause residues to scratch the frame surface during subsequent machining, affecting product quality. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this application provides a hole processing device for automotive mounting frames, which aims to at least partially solve the technical problems caused by the limited cleaning range of the chip-cutting method in related technologies and the inability to flexibly adjust the cleaning position as the automotive mounting frame rotates.

[0005] This application is achieved through the following technical solution: A hole-machining device for an automotive suspension frame, the device comprising: a support frame having opposing first and second sidewalls; clamping assemblies, each clamping assembly being provided on opposing sides of the first and second sidewalls, each clamping assembly having a rotatable connecting portion, the two ends of the automotive suspension frame being respectively connected to the connecting portions of the two clamping assemblies; and a cleaning assembly including a rotating wheel, a swing plate, a actuating block, an elastic element, and bristles; wherein: the rotating wheel is rotatably connected to opposing sides of the first and second sidewalls, the rotating wheel and the connecting portion are correspondingly arranged one-to-one, and the rotating wheel and the corresponding connecting portion are connected by a transmission mechanism. The rotating wheel has multiple toothed blocks spaced apart on its circumferential surface; the swing plate is rotatably connected between the first sidewall and the second sidewall, and the swing plate is located on the side of the two rotating wheels away from the connecting part; the elastic element connects the swing plate and the clamping assembly; the actuating block is disposed on the side of the swing plate facing the rotating wheel, and the actuating block and the rotating wheel are arranged in a one-to-one correspondence, and the actuating block can be abutted by the toothed block on the corresponding rotating wheel to drive the swing plate to swing relative to the support frame; multiple bristles are connected to the side of the swing plate facing the vehicle suspension frame, and at least a portion of the bristles are flexible.

[0006] The hole-machining equipment for an automotive mounting frame provided in this application belongs to the fields of cutting tool depth machining and CNC insert technology. Since the support frame of the machining equipment has a first side wall and a second side wall, and clamping components are provided on the opposite sides of the first side wall and the second side wall, and the clamping components have rotatable connecting parts, the two ends of the automotive mounting frame are respectively connected to the connecting parts of the two clamping components; therefore, the clamping components can be used to drive the automotive mounting frame to rotate, and then the turning workpiece can be used to open holes in the automotive mounting frame. Because the rotating wheel of the cleaning assembly is connected to the corresponding connecting part, the rotating wheel can be synchronously shifted when the connecting part rotates. Since the swing plate is rotatably connected between the first and second side walls, and the swing plate is located on the side of the two rotating wheels away from the connecting part, the actuating block is set on the side of the swing plate facing the rotating wheel. The actuating block and the rotating wheel are set one-to-one. The actuating block can be abutted by the toothed block on the corresponding rotating wheel to drive the swing plate to swing relative to the support frame. Since multiple bristles are connected to the side of the swing plate facing the car mount frame, at least part of the bristles are flexible. The bristles can swing synchronously with the swing plate relative to the support frame to sweep away the residue adhering to the surface of the car mount frame as it rotates, reducing the impact of residue accumulation on the subsequent processing accuracy, ensuring the stability and consistency of continuous operation, and preventing residue from scratching the frame surface during subsequent processing, thus ensuring product quality.

[0007] In some embodiments, the diameter of the connecting portion is larger than the diameter of the rotating wheel.

[0008] In some embodiments, both of the rotating wheels are provided with ventilation slots, which are arranged to extend through the axial direction parallel to the rotating wheels.

[0009] In some embodiments, first actuating blades are provided on opposite sides of the two rotating wheels, and a ventilation groove is provided between two adjacent first actuating blades.

[0010] In some implementations, a plurality of the first actuating blades are arranged in a spiral shape.

[0011] In some embodiments, the cleaning assembly further includes: two airbag assemblies disposed on the side of the swing plate facing the vehicle suspension frame, the airbag assemblies and the clamping assemblies being disposed in a one-to-one correspondence, the airbag assembly including one or more airbags, the airbags abutting against the corresponding clamping assemblies, and the airbags communicating with the interior of the swing plate; and multiple exhaust components disposed on the side of the swing plate facing the vehicle suspension frame, and all of the multiple exhaust components communicating with the interior of the swing plate.

[0012] In some embodiments, the exhaust component includes: an exhaust seat connected to the side of the swing plate facing the vehicle suspension frame, the exhaust seat having an exhaust port communicating with the swing plate.

[0013] In some embodiments, the exhaust mount has an opening on one side facing the vehicle mount frame; the exhaust mount also includes a second actuating blade inserted into the exhaust mount and protruding from the side of the exhaust mount facing the vehicle mount frame.

[0014] In some implementations, the airbag is equipped with a one-way air intake valve.

[0015] In some embodiments, the clamping assembly further includes a support plate, which is connected to opposite sides of the first sidewall and the second sidewall. The connecting portion includes a drive member, a gear, and a connecting disc. The drive member is connected to the support plate and has a rotatable output portion. The gear is connected to the output portion of the drive member, and the connecting disc is connected to the gear. The two ends of the vehicle suspension frame are respectively connected to the connecting discs of the two clamping assemblies. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] During the machining of holes in automotive suspension frames, it is often necessary to manually clamp the suspension frame repeatedly to adjust its position so that the holes are aligned with the turning head for different locations on the frame. This manual clamping method has many drawbacks: Firstly, each clamping may introduce a certain degree of error, and repeated clamping will lead to the accumulation of errors, making it difficult to guarantee the positional accuracy and concentricity of the holes, thus affecting the assembly quality of the automotive suspension frame with other components and reducing the overall performance of the vehicle; secondly, the manual clamping operation is cumbersome, consumes a lot of time and manpower, resulting in low processing efficiency and increased production costs.

[0021] Based on the above-mentioned technical problems, this application provides a hole processing device for automotive mounting frames, which can mechanically adjust the position of automotive mounting frames to ensure the positional accuracy and concentricity of the holes, improve processing efficiency, and reduce production costs.

[0022] Figure 1 A schematic diagram of the structure of a hole-machining device for an automotive mounting frame according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 An assembly diagram of the clamping components, cleaning components, and automotive suspension frame. Figure 3 It shows Figure 2 Assembly diagram with the car's suspension frame removed. (Connection) Figures 1-3 The present application provides a hole-machining device 10 for automotive suspension frames, comprising a support frame 100 and clamping components 200. The support frame 100 has opposing first sidewalls 110 and second sidewalls 120. Clamping components 200 are provided on opposing sides of the first sidewalls 110 and second sidewalls 120, and each clamping component 200 has a rotatable connecting portion 210. Both ends of the automotive suspension frame X are respectively connected to the connecting portions 210 of the two clamping components 200. When machining the holes of the automotive suspension frame X, the automotive suspension frame X is fixedly connected to the connecting portions 210 of the two clamping components 200 to achieve suspension of the automotive suspension frame X. Since both connecting portions 210 are rotatable, they can drive the automotive suspension frame X to rotate synchronously, thereby achieving mechanized adjustment of the position of the automotive suspension frame X. It can automatically rotate and accurately position to the target angle, thereby ensuring the positional accuracy and concentricity of the holes, improving processing efficiency, and reducing production costs.

[0023] join Figure 1In some embodiments, the support frame 100 is square, and the first sidewall 110 and the second sidewall 120 of the support frame 100 are arranged opposite each other along the horizontal longitudinal direction. Correspondingly, the vehicle suspension frame X also extends along the horizontal longitudinal direction. In addition, the clamping assembly 200 also includes a support plate 220, and the support plate 220 is connected to the opposite sides of the first sidewall 110 and the second sidewall 120 to realize the assembly of the clamping assembly 200 on the support frame 100.

[0024] join Figure 1 In some embodiments, the processing equipment 10 further includes a turning head 300, which is connected to the support frame 100 and located above the automotive mounting frame X. The turning head 300 can move relative to the support frame 100 in the horizontal, vertical, and longitudinal directions. After the automotive mounting frame X is fixed between the two support plates 220, the position of the automotive mounting frame X on the support frame 100 is adjusted by the clamping assembly 200 so that the position of the hole to be turned on the automotive mounting frame X is directly opposite the turning head 300. Then, the turning head 300 is automatically lowered to complete the turning operation on the lower automotive mounting frame X. Since the turning head 300 can move relative to the support frame 100 in the horizontal and longitudinal directions, turning of holes at different positions on the automotive mounting frame X can be achieved. For example, the processing equipment 10 also includes a connecting frame 400, a connecting rod 410, and a turning seat 420. Two connecting frames 400 are arranged opposite each other along the horizontal longitudinal direction. The two connecting frames 400 are connected to the first side wall 110 and the second side wall 120 in a horizontally lateral direction through a mechanism such as a ball screw mechanism. The tops of the two connecting frames 400 are connected to each other through the connecting rod 410. The turning seat 420 is connected to the connecting rod 410 in a horizontal longitudinal direction through a mechanism such as a ball screw mechanism. The turning head 300 can be vertically telescopically connected to the turning seat 420 through a hydraulic mechanism so that the turning head 300 can complete the turning operation of the automotive mounting hardware according to the preset instructions.

[0025] join Figure 2 as well as Figure 3 In some embodiments, the connecting portion 210 includes a drive member 211, a gear 212, and a connecting disk 213. The drive member 211 is connected to the support plate 220 and has a rotatable output portion. The gear 212 is connected to the output portion of the drive member 211, and the connecting disk 213 is connected to the gear 212. The two ends of the vehicle mounting frame X are respectively connected to the connecting disks 213 of the two clamping assemblies 200. By controlling the movement of the drive member 211, the gear 212 and the connecting disk 213 can be driven to rotate synchronously, thereby realizing the synchronous rotation of the vehicle mounting frame X. For example, the drive member 211 is a motor.

[0026] In the process of machining the aforementioned automotive mounting frame X, related technologies mostly use static cleaning devices to remove chips, such as fixed brushes or air blowing devices. The cleaning range is limited, and the cleaning position cannot be flexibly adjusted as the automotive mounting frame X rotates. It is difficult to thoroughly clean the complex parts such as the inside of the frame and the walls of the holes, which leads to the easy accumulation of chips and residues in these areas.

[0027] Figure 4 It shows Figure 2 Enlarged diagram at point A in the diagram, combined with... Figures 2-4 Based on this, the processing equipment 10 provided in this application also includes a cleaning assembly 500, which includes a rotating wheel 510, a swing plate 520, a toggle block 530, an elastic element 540, and bristles 550; wherein: the rotating wheel 510 is rotatably connected to the opposite sides of the first sidewall 110 and the second sidewall 120, the rotating wheel 510 and the connecting part 210 are arranged in a one-to-one correspondence, the rotating wheel 510 and the corresponding connecting part 210 are connected in a transmission manner, and a plurality of tooth blocks 511 are spaced apart on the circumferential surface of the rotating wheel 510; the swing plate 520 is rotatably connected to the first sidewall 110 and the second sidewall 120. Between 0 and 0, and the swing plate 520 is located on the side of the two rotating wheels 510 away from the connecting part 210; the elastic member 540 connects the swing plate 520 and the clamping assembly 200; the actuating block 530 is disposed on the side of the swing plate 520 facing the rotating wheel 510, and the actuating block 530 and the rotating wheel 510 are disposed in a one-to-one correspondence, and the actuating block 530 can be abutted by the toothed block 511 on the corresponding rotating wheel 510 to drive the swing plate 520 to swing relative to the support frame 100; a plurality of bristles 550 are connected to the side of the swing plate 520 facing the vehicle suspension frame X, and at least a portion of the bristles 550 are flexible.

[0028] In this application, since the rotating wheel 510 of the cleaning assembly 500 is connected to the corresponding connecting part 210, the rotating wheel 510 can be synchronously shifted when the connecting part 210 rotates. Since the swing plate 520 is rotatably connected between the first side wall 110 and the second side wall 120, and the swing plate 520 is located on the side of the two rotating wheels 510 away from the connecting part 210, the actuating block 530 is disposed on the side of the swing plate 520 facing the rotating wheel 510. The actuating block 530 and the rotating wheel 510 are arranged in a one-to-one correspondence, and the actuating block 530 can be driven by the corresponding rotating wheel 510. The toothed block 511 on the 0 abuts against the swing plate 520 to drive it to swing relative to the support frame 100. Since multiple bristles 550 are connected to the side of the swing plate 520 facing the car mount frame X, at least a portion of the bristles 550 are flexible. The bristles 550 can swing synchronously with the swing plate 520 relative to the support frame 100 so that the residue adhering to the surface of the car mount frame can be swept off as it rotates, reducing the impact of residue accumulation on the subsequent processing accuracy, ensuring the stability and consistency of continuous operation, and preventing residue from scratching the frame surface in subsequent processing, thus ensuring product quality.

[0029] In some embodiments, the rotating wheel 510 of the sweeping assembly 500 is disposed below the gear 212 of the clamping assembly 200. The toothed blocks 511 on the circumferential surface of the rotating wheel 510 mesh with the gear 212 of the clamping assembly 200, so that when the car suspension frame X is driven to rotate by the clamping assembly 200, the rotating wheel 510 is driven to rotate synchronously, so as to remove the chips from the car suspension frame X. This eliminates the need for a separate drive mechanism to drive the sweeping assembly 500, thereby saving costs and reducing power consumption.

[0030] In some embodiments, the diameter of the connecting portion 210 is larger than the diameter of the rotating wheel 510, that is, the diameter of the gear 212 of the clamping assembly 200 is larger than the diameter of the rotating wheel 510. With this configuration, when the gear 212 rotates the rotating wheel 510 through the tooth block 511, the rotational speed of the rotating wheel 510 is much higher than the rotational speed of the gear 212 itself, forming an acceleration transmission effect, which greatly increases the frequency of the rotated wheel 510, thereby increasing the oscillation and oscillation frequency of the oscillating plate 520 and the bristles 550 synchronously, ensuring that the chips are removed instantly and completely during rapid oscillation.

[0031] Figure 5 A schematic diagram of the rotating wheel is shown, showing its connection. Figure 4 as well as Figure 5In some embodiments, both rotating wheels 510 are provided with ventilation slots 512, which are arranged through the axial direction parallel to the rotating wheels 510. During the rotation of the rotating wheels 510 driven by the gear 212, airflow is generated in the ventilation slots 512. This airflow blows towards the automotive mounting frame X being processed, thereby cleaning the chips in the automotive mounting frame X. This arrangement allows for chip cleaning without utilizing a fan or other blowing mechanism, saving costs and reducing power consumption.

[0032] join Figure 4 as well as Figure 5 In some embodiments, first actuating blades 513 are provided on opposite sides of the two rotating wheels 510, and a ventilation slot 512 is provided between two adjacent first actuating blades 513. The rapid rotation of the rotating wheels 510 actuates the air through the first actuating blades 513, causing the air to flow rapidly. This, combined with the bristles 550, allows the turning debris to be blown away quickly. Simultaneously, the ventilation slot 512 allows air to pass through from the outside of the rotating wheels 510 when the first actuating blades 513 actuate the air, forming a directional airflow channel, further enhancing the directional discharge effect of the debris. For example, multiple first actuating blades 513 are arranged in a spiral shape, forming a composite airflow that propels the workpiece along the rotational axis using a spiral airflow (vortex), forcibly carrying the chips away from the cutting area and discharging them along a predetermined path, thereby further achieving powerful directional chip removal and improving the cleaning effect.

[0033] join Figure 4 In some embodiments, the swing plate 520 is disposed below the clamping assembly 200. The two ends of the swing plate 520 are rotatably connected to the first side wall 110 and the second side wall 120 respectively via the pivot 521. The elastic element 540 can be a spring, which connects the swing plate 520 and the support plate 220 of the clamping assembly 200 for resetting the swing plate 520.

[0034] join Figure 4 In some embodiments, the cleaning assembly 500 further includes two airbag assemblies and multiple exhaust components 570. The two airbag assemblies are respectively disposed on the side of the swing plate 520 facing the vehicle suspension frame X. Each airbag assembly corresponds to a clamping assembly 200. Each airbag assembly includes one or more airbags 560, which abut against the corresponding clamping assembly 200. The airbag 560 is internally connected to the swing plate 520. Multiple exhaust components 570 are disposed on the side of the swing plate 520 facing the vehicle suspension frame X, and all exhaust components are internally connected to the swing plate 520. The advantage of this arrangement is that: Because the swing plate 520 swings and bounces back and forth through the spring, it completes the reciprocating swinging work. During the reciprocating swinging, the airbag 560 on the swing plate 520 is continuously squeezed. The top of the airbag 560 is restricted by the bottom of the support block. Therefore, as the swing plate 520 swings continuously, the airbag 560 is repeatedly compressed and released between the swing plate 520 and the support block, resulting in regular deformation. During the deformation process, the airbag 560 continuously compresses air and discharges it through the swing plate 520 and the exhaust part of the exhaust component 570, completing the one-way discharge of air. This continuously blows and cools the outside, forming a dynamic air pressure difference to accelerate the removal of residue from the inner wall of the car suspension frame X. In addition, the periodic deformation of the airbag 560 also drives the internal flow field disturbance of the exhaust component 570, improving the airflow's ability to entrain fine chips and further improving the cleaning effect.

[0035] join Figure 5 For example, each airbag assembly is arranged side-by-side with the elastic element 540 below the support block. Each airbag assembly includes two or more airbags 560, which are all located at the ends of the swing plate 520 and communicate with the interior of the swing plate 520. In addition, the airbags 560 are provided with one-way air intake valves 561 for one-way air intake to ensure stable airflow circulation.

[0036] Figure 6 A structural schematic diagram of the exhaust component 570 is shown. (Connection) Figure 6 In some embodiments, the exhaust element 570 and the brush bristles 550 are spaced apart. The exhaust element 570 includes an exhaust seat 571 connected to the side of the swing plate 520 facing the vehicle suspension frame X. The exhaust seat 571 is provided with an exhaust port 572, which communicates with the swing plate 520. Air introduced from the airbag 560 can be blown towards the vehicle suspension frame X through the exhaust port 572 to achieve chip removal. Exemplarily, the bottom of the exhaust seat 571 communicates with the top of the swing plate 520, and the exhaust seat 571 is open on the side facing the vehicle suspension frame X, that is, the top of the exhaust seat 571 is open, and the top of the exhaust seat 571 is configured as the exhaust port 572.

[0037] In some embodiments, the exhaust seat 571 further includes a second deflector blade 573, which is inserted into the exhaust seat 571 and protrudes from the exhaust seat 571 towards the side facing the vehicle mount frame X. The swing plate 520, the fixed seat, and the second deflector blade 573 can swing synchronously. The second deflector blade 573 will deflect the air to form a certain upward trend. This, combined with the lateral airflow deflected by the rotating wheel 510 and the first deflector blade 513, converges with the upward airflow generated by the second deflector blade 573, allowing the airflow to rise and pass through the inner cavity of the vehicle mount frame X. As a spiral cyclone is formed inside the vehicle mount frame X, it carries away machining debris, improving exhaust efficiency and cleanliness. Exemplarily, the second deflector blade 573 extends longitudinally in the horizontal direction.

[0038] In summary, the hole-machining equipment 10 for automotive mounting frames X provided in this application can mechanically adjust the position of the automotive mounting frame X through the clamping assembly 200 to ensure the positional accuracy and concentricity of the holes, improve processing efficiency, and reduce production costs. Furthermore, the power of the clamping assembly 200 drives the cleaning assembly 500 to ensure that the chips are removed without the need for a power mechanism. In addition, the chip cleaning effect is improved by the airbag assembly and the exhaust seat 571, making it highly practical.
