Description

Technical Field

[0001] The invention relates to the technical field of automobile parts grinding, in particular to a device and method for grinding an anti-scratch strip of a vehicle safety belt slide plate. Background Art

[0002] The seat belt slide plate is mainly used to adjust the height of the top of the seat belt on the car's B-pillar. This design allows passengers to freely adjust the position of the seat belt according to their height and comfort, thereby ensuring that the seat belt can protect passengers more effectively in the event of a collision. The anti-scratch strip acts as a guide rail to guide the seat belt slide plate to slide smoothly on the car's B-pillar. This design not only ensures the stability of the seat belt, but also prevents the slide plate from causing wear or scratches to the interior of the car during the sliding process.

[0003] The surface of the anti-scratch strip usually has a flexible anti-scratch layer. This design not only increases the sliding resistance of the skateboard, but also provides additional protection to prevent direct contact between the skateboard and the B-pillar.

[0004] The anti-scratch strip of the car seat belt slide is usually divided into a hard rubber buckle used to be fixed on the plastic door panel, and a flexible anti-scratch layer that plays a role of barrier sealing and reducing friction. The hard rubber buckle is extruded during production. After cooling, the inner wall of the card slot needs to be ground to remove the rough burrs on the surface and ensure a smooth surface, so that the anti-scratch strip of the car seat belt slide is more docile when used. However, if Figure 1 As shown, since some existing automobile seat belt slide anti-scratch strip grooves have multiple chamfer points, the grinding process takes a long time, increasing the time cost; therefore, it does not meet the existing needs. In this regard, we propose a vehicle seat belt slide anti-scratch strip grinding device and method. Summary of the invention

The piston plate overcomes the force of the reset spring and squeezes out the air in the gas-filled piston cylinder. Since there are one-way valves at the mouths of the air inlet pipe and the air delivery pipe, the air is squeezed into the air delivery pipe and finally enters the water outlet to mix with the water flow and spray out, increasing the fluidity and strength of the water flow, not only maintaining a strong cooling effect, but also timely washing away the powder generated by grinding, ensuring that it is not affected during fine grinding, thereby improving the polishing effect of the anti-scratch strip. When the protrusion is staggered with the piston handle, the piston plate is reset and retreated by the elastic force of the reset spring, and at this time, the outside air is sucked into the gas-filled piston cylinder through the air inlet pipe.

[0041] See Figure 2 and Figure 4A top plate 150 is installed on the top of the vertical plate 110, and a clamping plate 160 is connected to the end of the top plate 150. An active clamping wheel 510 and a plurality of driven clamping wheels 520 are rotatably installed on the side of the clamping plate 160 adjacent to the grinding wheel 310. The active clamping wheel 510 and the driven clamping wheel 520 are used to clamp and transmit the anti-scratch strip of the car seat belt skateboard. A support plate 170 is installed on the side of the clamping plate 160 away from the grinding wheel 310. A conveying motor 190 is installed on the support plate 170. The conveying motor 190 is connected to the active clamping wheel 510, and a connecting belt 530 is installed between the rotating shaft of the active clamping wheel 510 and the rotating shaft of the driven clamping wheel 520 on the same side.

[0042] See Figure 5 A spray box 610 is fixedly installed on the top of the support rod 330, a top wheel 620 is rotatably installed in the middle of the spray box 610, and the top wheel 620 rolls and fits with the inner wall of the anti-rubbing strip of the moving car seat belt slide. A spray disc 630 for cooling the anti-rubbing strip of the car seat belt slide is rotatably installed on the side of the spray box 610, and a water outlet 631 is opened on the side of the spray disc 630. A water pipe 632 is installed inside the spray box 610, one end of the water pipe 632 is connected to a water source, and the other end of the water pipe 632 is connected to the water outlet 631;

[0043] A disc 640 for enhancing the cooling and flushing effects is rotatably installed inside the spray box 610 . The disc 640 is coaxially connected to the top wheel 620 , and the disc 640 is transmission-connected to the spray disc 630 .

[0044] In the specific configuration, the active clamping wheel 510 and the driven clamping wheel 520 on the same side are driven by a connecting belt 530 , and the driven clamping wheel 520 and the driven clamping wheel 520 on the same side are also connected by a connecting belt 530 for transmission.

[0045] See Figure 3 A driving bevel gear 340 is installed at the bottom of the rotating cylinder 320, and a plurality of ball bearings 341 are installed at the bottom of the driving bevel gear 340. A ring groove 331 is opened at the top of the support rod 330, and the ball bearings 341 are rollingly engaged in the ring groove 331. An output bevel gear 350 is rotatably installed on the side of the side plate 130. One end of the output bevel gear 350 is connected to the grinding motor 180, and the other end of the output bevel gear 350 is meshed with the driving bevel gear 340. A water-blocking umbrella 360 for water blocking is installed in the middle of the rotating cylinder 320.

[0046] The power of the grinding motor 180 is transmitted to the rotating cylinder 320 through the meshing of the output bevel gear 350 and the driving bevel gear 340 , and the grinding wheel 310 is driven to rotate by the rotating cylinder 320 , thereby achieving the grinding effect.

[0047] See Fig.11The arrangement of the annular groove 331 and the ball bearing 341 not only provides support for the rotating cylinder 320, but also improves the smoothness of the rotation of the rotating cylinder 320, converts the sliding friction into rolling friction, and reduces the resistance during rotation.

[0048] By setting the water-blocking umbrella 360, the water flow from above will be blocked, thereby reducing the corrosion of the driving bevel gear 340 and the output bevel gear 350. In addition, in this embodiment, a drainage channel 121 is opened on the side of the bottom plate 120, and the flushing water flow is discharged to the outside.

[0049] This embodiment also provides a method for grinding an anti-scratch strip of a vehicle seat belt slide plate, comprising the following specific steps:

[0050] S1. Clean the surface: Before polishing, use a cleaning cloth to clean the dirt and dust on the surface of the anti-scratch strip;

[0051] S2. Rough grinding: Use the grinding wheel 310 for rough grinding, mainly to remove protrusions and scratches on the surface of the anti-friction strip;

[0052] S3. Fine grinding: Use a polishing wheel 370 to remove the wear marks and scratches left by rough grinding;

[0053] S4. Rinse and dry: Rinse with water to remove the powder produced during grinding and air dry.

[0054] In this embodiment: by setting the grinding wheel 310, it is made to contact with the four chamfered positions of the anti-scratch strip buckle at the same time, so as to achieve the effect of grinding four points at the same time, and by the cooperation of the active clamping wheel 510 and the driven clamping wheel 520, the anti-scratch strip can be clamped, lifted and actively transmitted, so that the anti-scratch strip moves while grinding, ensuring the uniformity of grinding time and improving the uniformity of grinding. In addition, the first side roller 220 and the second side roller 240 are provided to limit the two sides of the anti-scratch strip, so that the anti-scratch strip cannot move too much left and right during grinding, thereby reducing the grinding error and improving the grinding accuracy.

[0055] At the same time, a spray box 610 is installed on the top of the support rod 330, and a spray disc 630 is used to cool the anti-scratch strip to ensure the grinding process.

[0056] Embodiment 2: This embodiment is intended to solve the problem that the anti-scratch strip to be processed has four chamfers, and the cooling effect at the chamfer on the lower side is poor when water is sprayed from top to bottom for cooling. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 11A convex shaft 710 is rotatably installed on the side of the disc 640, a slide rail 750 is provided in the spray box 610, a slider 740 is slidably installed in the slide rail 750, a rack 730 is installed on the side of the slider 740, a crank connecting rod 720 is hinged to the convex shaft 710, and the other end of the crank connecting rod 720 is hinged to the rack 730, and the spray disc 630 is set as a half-toothed turntable, and the rack 730 is meshed with the teeth of the spray disc 630.

[0057] A water pump is installed on the side of the vertical plate 110 of the device, and the water pump is connected to the water pipe 632 so that water from the water source actively flows into the water pipe 632.

[0058] The bottom plate 120 is also provided with a polishing wheel 370 for fine grinding the chamfer of the anti-friction strip buckle of the car seat belt slide. The polishing wheel 370 has a finer mesh number, and the setting method of the polishing wheel 370 is consistent with the grinding wheel 310. A transmission box 140 is installed on the outside of the side plate 130. The transmission box 140 includes a first box body 141 and a second box body 142. The first box body 141 corresponds to the grinding wheel 310, and the second box body 142 corresponds to the polishing wheel 370. The grinding motor 180 is installed on the outside of the first box body 141, and a transmission belt 143 is installed between the rotating shafts of the first box body 141 and the second box body 142.

[0059] A limit plate 210 is installed on the side of the vertical plate 110, and a plurality of first side rollers 220 are rotatably installed below the limit plate 210. A second side roller 240 is rotatably installed on the side plate 130. The first side roller 220 and the second side roller 240 are located on both sides of the grinding wheel 310 and the polishing wheel 370. By arranging the polishing wheel 370 of the same specification on the bottom plate 120, the anti-scratch strip can be automatically fine-ground after the rough grinding, thereby enhancing the grinding effect of the chamfer of the anti-scratch strip and making its surface smoother.

[0060] In this embodiment: through the setting of the disc 640, when the top wheel 620 contacts and rotates with the moving anti-scratch strip, the disc 640 will also rotate, and through the cooperation of the convex shaft 710 and the crank connecting rod 720, the sliding rack 730 will become a reciprocating slide, and through the engagement of the rack 730 with the spray disc 630, the spray disc 630 is made to reciprocate, so that the water flow at the water outlet 631 is oscillating spray, which expands the water spraying range, not only cools down the position being polished, but also continues to cool down the position after polishing, so that the polishing effect of the anti-scratch strip of the car seat belt slide plate is further improved.

[0061] Embodiment 3: This embodiment aims to solve the problem that if the powder produced during rough grinding is not cleaned before fine grinding, the grinding effect will be affected. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 11A bump 810 is provided on the side of the disc 640, and an air-filling piston cylinder 820 is installed inside the spray box 610. One end of the air-filling piston cylinder 820 is connected to an air inlet pipe 830, and the air inlet pipe 830 runs through the spray box 610. A piston handle 850 is slidably installed on the other end of the air-filling piston cylinder 820. One end of the piston handle 850 is intermittently in contact with the bump 810, and the other end of the piston handle 850 is connected to a piston plate 860. The piston plate 860 slides and fits with the inner wall of the air-filling piston cylinder 820. An air supply pipe 840 is connected between the air-filling piston cylinder 820 and the spray disc 630, and the air supply pipe 840 is connected to the water outlet 631, which is helpful for mixing air and water and spraying them out during the fine grinding process, thereby improving the cleaning effect and thus improving the polishing effect of the anti-scratch strip.

[0062] It should be noted that, in this embodiment, a plurality of protrusions 810 may be provided, and the protrusions 810 may be in contact with the piston handle 850 periodically.

[0063] A return spring 870 is installed between the piston plate 860 and the inner wall of the gas piston cylinder 820. Check valves are provided at the pipe openings of the air inlet pipe 830 and the air delivery pipe 840, and the check valves are provided in opposite directions. When the piston plate 860 moves forward, the air is squeezed into the air delivery pipe 840 and does not flow back to the air inlet pipe 830.

[0064] In this embodiment: by setting a protrusion 810 on the side of the disc 640, during the rotation of the disc 640, the disc 640 will hit the piston handle 850, causing the piston handle 850 to move outward, and the piston plate 860 overcomes the force of the return spring 870 to squeeze out the air in the gas piston cylinder 820. Since there are one-way valves at the mouths of the air inlet pipe 830 and the air delivery pipe 840, the air is squeezed into the air delivery pipe 840, and finally enters the water outlet 631 to mix with the water flow and spray out, increasing the fluidity and strength of the water flow, not only maintaining a strong cooling effect, but also being able to timely wash away the powder generated by grinding, ensuring that it is not affected during fine grinding, thereby improving the polishing effect of the anti-friction strip. When the protrusion 810 and the piston handle 850 are staggered, the piston plate 860 is reset and retreated by the elastic force of the return spring 870, and at this time, the outside air is sucked into the gas piston cylinder 820 through the air inlet pipe 830.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
