Description

Technical Field

[0001] The present invention relates to the technical field of surface treatment devices, and specifically relates to an adaptive surface treatment device for automotive sensor housings. Background Art

[0002] As a key component for protecting the internal components of an automotive sensor, the surface quality of the sensor housing is directly related to the performance, reliability, and service life of the sensor. In order to make its surface flat, it is usually necessary to grind the burrs on the sensor housing. After retrieval, a patent with the Chinese patent publication number CN114800242B discloses a surface treatment device for processing sensor housings. Although this device uses a frustum-shaped barrel with a larger top and a smaller bottom, which enables the sand grains to accumulate quickly, the interval to decrease, and the friction to increase, resulting in better deburring effect for the metal housing of the sensor, and the sand grain addition speed is slow, which is convenient for discharging. However, due to the complex flow channel of the grinding sand grains inside this device, and because the flowability of the grinding sand grains themselves is poor, it is easy to cause blockage of the grinding sand grains inside when passing through the narrow conduction notch at the bottom of this device. At the same time, due to the presence of the grinding sand grains inside this device, the feeding port is blocked, making it inconvenient for secondary feeding, thus resulting in more troublesome use. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an adaptive surface treatment device for automotive sensor housings, which solves the problems that the existing device has a narrow and complex internal sand grain flow channel, resulting in easy blockage of the grinding sand grains during the flow process, and the existing device is inconvenient for secondary feeding mentioned in the background art.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An adaptive surface treatment device for automotive sensor housings includes a base, a grinding mechanism, a switching mechanism, and a filtering mechanism. On both sides of the top of the base, there are brackets. There are two brackets, and one end of the bottom of the two brackets is welded to the base. On one side of one of the brackets, there is a controller, which is used to control the overall device. The tops of the two brackets are bolted with a first motor. There are two first motors, and the output ends of the two first motors are respectively connected to both sides of the grinding mechanism. The inside of the grinding mechanism is used to place the sensor housing. At one end of the bottom and the top of the grinding mechanism, there are connecting pipes. The other end of the connecting pipe is installed with a switching mechanism. One end of the inside of the connecting pipe is communicated with the inside of the grinding mechanism, and the other end of the inside of the connecting pipe is communicated with the inside of the switching mechanism. The other end of the switching mechanism is installed with a storage bin. Inside the storage bins on both sides of the grinding mechanism, two different particle size abrasive sands are filled. The other end of the storage bin is installed with a filtering mechanism. The inside of the filtering mechanism is communicated with the inside of the storage bin, and the filtering mechanism is used to filter the abrasive sands.

[0005] Preferably, the grinding mechanism includes a grinding chamber. The two sides of the grinding chamber are respectively sleeved outside the output end of the first motor. The two ends of the grinding chamber are welded to the connecting pipes. Two circular holes are provided on the surface of the grinding chamber, and the two circular holes on the surface of the grinding chamber are symmetrically distributed. A connecting ring is welded to the inner wall of the circular hole on the surface of the grinding chamber. There are two connecting rings. The two connecting rings are respectively welded to both ends of the limiting rod. There are multiple limiting rods, and the limiting rods are annularly and equidistantly distributed between the two connecting rings. The annular and equidistant distribution of the limiting rods between the two connecting rings can ensure that the sensor housing can be evenly supported and fixed when placed inside the grinding chamber. During the grinding process, the sensor housing can be stably maintained at the central position of the grinding chamber, avoiding local over-grinding or under-grinding caused by position deviation, thereby improving the uniformity and quality of grinding. Two symmetrically distributed circular holes are provided on the surface of the grinding chamber. This symmetric design makes it more convenient to place and remove the sensor housing. The operator can put the sensor housing into or take it out from any one of the holes, improving the flexibility and convenience of the operation. The two ends of the grinding chamber are connected to the storage chamber through the connecting pipes. This linear channel design enables the grinding grit to smoothly enter the grinding chamber during the flow process and contact the sensor housing. This design avoids the blockage of the grit during the flow process, improving the utilization rate of the grit and the grinding efficiency.

[0006] Preferably, a sealing cover is provided inside the two circular holes on the surface of the grinding chamber. The outer wall of the sealing cover is closely attached to the inner wall surface of the grinding chamber. One side of the sealing cover is in a protruding structure, and the inside of the sealing cover is in a hollow structure. Two handles are welded to the surface of the sealing cover. Limiting grooves are annularly and equidistantly provided on the surface of the sealing cover. The annular and equidistant limiting grooves provided on the surface of the sealing cover cooperate with the sliding rods, enabling the sealing cover to slide along a preset track during the installation and disassembly process. This design not only improves the installation accuracy of the sealing cover but also prevents the sealing cover from shifting or jamming during the operation, further enhancing the convenience of the operation.

[0007] Preferably, one end of the limiting groove is in a circular shape structure, and the other end of the limiting groove is in an arc shape structure. The inner wall of the limiting groove is in sliding contact with the outer wall of the sliding rod. A limiting block is welded to one end of the sliding rod. The limiting block is in a circular shape structure, and the outer diameter of the limiting block is equal to the inner diameter of one end of the limiting groove. The other end of the sliding rod is welded to the outer wall of the grinding chamber. The sealing cover is connected to the grinding chamber through a positioning bolt. One end of the limiting groove is circular and the other end is arc-shaped. This design enables the limiting block to slide along the track of the limiting groove, thereby realizing the quick positioning of the sealing cover. When the limiting block is aligned with the circular end of the limiting groove, the sealing cover can be easily inserted or pulled out; when the sealing cover is rotated by a certain angle, the limiting block enters the arc section, thereby fixing the sealing cover on the grinding chamber.

[0008] Preferably, the switching mechanism includes a mounting ring, one end of the mounting ring is welded to the connecting pipe, and the other end of the mounting ring is welded to the storage bin, a valve plate is arranged inside the mounting ring, the valve plate has a circular structure, and connecting shafts are welded at both ends of the valve plate, the connecting shaft at one end of the valve plate is rotatably connected to the inner wall of the mounting ring, the connecting shaft at the other end of the valve plate is transmission-connected to the output end of the second motor through a gear, the second motor is mounted on one side of the fixed shell by screws, the other end of the fixed shell is connected to the outer wall of the mounting ring by screws, the valve plate has a circular structure, is mounted inside the mounting ring, and is connected at both ends by The shaft is connected to the mounting ring. This design allows the valve plate to rotate around the connecting shaft, thereby opening and closing the gravel abrasive flow channel. By controlling the rotation angle of the valve plate, gravel abrasives of different particle sizes can be accurately switched to meet the different needs of coarse grinding and fine grinding. The switching mechanism works in coordination with other components such as the grinding mechanism and the filtering mechanism. Through the unified scheduling of the controller, the entire grinding process is automated. For example, in the coarse grinding stage, the switching mechanism guides coarser gravel abrasives into the grinding chamber; in the fine grinding stage, it switches to finer gravel abrasives, thereby improving the grinding quality.

[0009] Preferably, the filtering mechanism includes a waste bin, which is connected to one end of the storage bin by screws, a bottom cover is arranged on the outside of the waste bin, the bottom cover is threadedly connected to the waste bin, holes and grooves are opened on the surface of the waste bin for discharging, a baffle is arranged inside the waste bin, a filter plate is arranged on one side of the baffle, the filter plate is installed inside the waste bin, and is used to separate worn waste gravel and unworn gravel abrasives, through the screening of the filter plate, smaller waste gravel is collected in the waste bin, while gravel abrasives with larger particle size can continue to be recycled, this design effectively improves the utilization rate of gravel abrasives and reduces waste of resources, the baffle is arranged in a semicircular or horizontal shape, and is used in conjunction with the filter plate to further enhance the filtering effect, the baffle can prevent the waste gravel from being mixed back into the storage bin during the flipping of the equipment, thereby ensuring that the filtered gravel abrasives remain clean and the grinding quality is improved.

[0010] Preferably, the baffle has a semicircular structure, the outer wall of the baffle is welded to the inner wall of the waste bin, and the surface of one end of the bottom of the sieve plate is evenly provided with holes and grooves. There is a cavity between the bottom of the baffle and the bottom of the waste bin for storing waste. There is a cavity between the bottom of the baffle and the bottom of the waste bin, which is specifically used to store filtered waste gravel. This design allows the waste gravel to be stored in a centralized manner to avoid its accumulation inside the waste bin, thereby reducing the difficulty of cleaning and ensuring the cleanliness of the inside of the waste bin. The surface of one end of the bottom of the sieve plate is evenly provided with holes and grooves, which are used to screen the waste gravel. The evenly distributed holes and grooves can ensure that the gravel is evenly filtered when passing through the sieve plate, avoiding problems such as incomplete filtration or local blockage due to uneven distribution of holes and grooves. This design improves the filtration efficiency and ensures that only waste gravel that meets the particle size requirements can enter the waste cavity.

[0011] Preferably, the baffle is arranged horizontally, and one side of the baffle is inclined. There is an angle between the sieve plate and the baffle. A linear channel is formed between the storage bin and the grinding bin through a connecting pipe. The linear flow path reduces the resistance of the grit during transmission, avoiding the problem of grit blockage caused by narrow or complex channels. The linear channel design enables the grit to flow smoothly from the storage bin into the grinding bin, improving the operating efficiency of the equipment. The linear channel reduces the collision and wear of the grit during transmission, extending the service life of the grit. This design not only improves the utilization rate of the grit but also reduces the wear inside the equipment and extends the service life of the equipment.

[0012] The present invention provides a surface treatment device for an adaptive automotive sensor housing, which has the following beneficial effects:

[0013] (1) For the surface treatment device for an adaptive automotive sensor housing, when in use, the operator opens the sealing cover, places the sensor housing between the limiting rods inside the grinding bin, and then closes the sealing cover. After the first motor starts, it drives the grinding bin to rotate, and then drives the two connecting pipes at both ends of the grinding bin to rotate 180 degrees synchronously with the storage bin, so that the grinding grit in the top storage bin flows downward. During the flow process, the grinding grit contacts the sensor housing inside the grinding bin and adapts to the shape of the sensor housing by virtue of its fluidity, effectively removing the burrs on its surface. As the first motor continuously drives the grinding bin to rotate, the grinding grit circulates inside the grinding bin, comprehensively grinding the sensor housing. During this process, the grinding grit flows in a straight line, with good fluidity, avoiding the occurrence of blockage phenomena, and significantly improving the reliability of the device.

[0014] (2) For the surface treatment device for an adaptive automotive sensor housing, when the sensor housing inside needs to be taken out or secondary feeding is required after grinding, when the grinding bin of the device is in a vertical state, the first motor stops driving the device to rotate, so that the grinding grit inside the device can fall into the connecting pipe at the bottom. Then, by removing the positioning bolts and grasping the handle to rotate the sealing cover, the sliding rod can slide inside the limiting groove on the surface of the sliding rod, so that the limiting block can be aligned with the circular hole groove at one end of the limiting groove, and then the sealing cover can be pulled outwards to be removed. Thus, it is convenient to take out the sensor housing inside or perform secondary feeding through the circular hole groove on the outer wall of the grinding bin, greatly improving the convenience of use. When closing the sealing cover, only by aligning one end of the limiting groove with the limiting block and then rotating the sealing cover can the sealing cover be quickly installed, and the position of the sealing cover is fixed by the set bolt, improving the convenience of installing the sealing cover and being beneficial to improving the operation efficiency.

[0015] (3) In this adaptive surface treatment device for automotive sensor housings, only one switching mechanism is in the open state during operation. When the switching mechanism in the open state is at the bottom, the grinding grit will fall into the storage bin through the open switching mechanism. The valve plate is driven by the second motor below to rotate, so that the valve plate of the switching mechanism below can be closed, enabling the coarser grinding grit to be enclosed inside the storage bin below. At the same time, the valve plate of the switching mechanism above is opened under the drive of the second motor, allowing the finer grinding grit inside the storage bin above to fall. As the first motor drives the grinding bin to flip, the sensor housing inside the grinding bin can be finely ground by the finer grinding grit after rough grinding, which is conducive to improving the surface grinding treatment effect of the sensor housing.

[0016] (4) In this adaptive surface treatment device for automotive sensor housings, during the flipping process of the device, the grinding grit with less wear inside the storage bin can enter the cavity between the filter plate and the waste bin through the filter plate. During the flipping of the device, due to the occlusion of the baffle and one end of the inclined filter plate, the filtered waste grinding grit inside the waste bin will not return to the storage bin through the filter plate, enabling the filtered waste grinding grit to be stored inside the waste bin all the time. Then, by opening the bottom cover, the waste grinding grit can be discharged. Furthermore, by rotating the waste bin with the discharged grit to the top through the first motor and removing the connecting bolts of the waste bin, new grinding grit can be added inside, enabling the device to always maintain a good grinding effect.

[0017] Thus, it solves the problems that the internal grit flow channel of the existing device is narrow and complex, resulting in easy blockage of the grinding grit during the flow process, and the existing device is not convenient for secondary feeding. BRIEF DESCRIPTION OF THE DRAWINGS
