Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle front hood processing, in particular to a surface polishing device for a vehicle front hood. Background Art

[0002] The front hood of a car can protect the engine and surrounding pipelines, etc. Under the front hood are important parts of the car, including the engine, circuit, brake system, transmission system and other important parts of the vehicle. By improving the strength of the front hood, it can fully prevent adverse effects such as chipping, corrosion, rain and electrical interference, and fully protect the normal operation of the vehicle. However, due to the presence of multiple complex curved surfaces on the front hood, the front hood cannot be fixed by the equipment, so manual adjustment is often required during the polishing process, and the overall processing efficiency is low. Therefore, some equipment designs that can automatically complete the surface polishing of the front hood of the car have emerged.

[0003] For example, patent application number CN202211087007.2 discloses a surface polishing device for the front hood of a vehicle, including a base, wherein four sliding grooves are arranged inside the upper end of the base. The second fixed frame can rotate with the center of the limit plate as the axis through the limit plate, so that the second fixed frame drives the rotating motor to rotate, so that the polishing wheel can be close to the surface of the hood, thereby increasing the effective polishing area of ​​a single position, and the fixed plate is pushed by two groups of second cylinders to be fixed at the four corners of the upper and lower surfaces of the hood. The fixed ball can rotate in the middle of the fixed plate, thereby changing the direction of the fixed plate. The fixed plate adjusts the direction of the fixed plate according to the arc surface of the hood, so that the hood can be stably fixed on the polishing device. Through the combined use of the fixed structure and the polishing structure, the polishing efficiency and polishing accuracy of the device are improved.

[0004] In the prior art, the second fixing frame and the fixing plate are arranged so that the front hood of the vehicle can be automatically fixed and polished, but there are still certain deficiencies in the overall use process: although the prior art completes the automatic clamping process through multiple fixing plates, the front hood is large in size and has a certain elasticity. It is clamped only at four end points, and the stability of the position near the polishing point cannot be guaranteed during high-speed polishing. It is easy to generate vibration near the polishing point, which seriously affects the overall polishing effect. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a surface polishing device for the front hood of an automobile. During the process of completing automatic polishing, the device designed by the utility model can not only perform shockproof reinforcement treatment near the polishing point, but also spray a large amount of cutting fluid nearby, so that waste chips and dirt can be discharged in time, thereby improving the polishing accuracy.

[0009] Preferably, a rough surface pad is provided at the center of the outer end surface of the spherical sleeve. The provision of the rough surface pad ensures the basic clamping and fixing quality.

[0010] Preferably, a plurality of elastic arc plates are evenly arranged on the outer end surface of the water hose in a straight line direction, and a plurality of convex strips are arranged on the outer arc surface of each elastic arc plate.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0024] Embodiment 1:

[0025] refer to Figure 1-7 A surface polishing device for a front hood of an automobile comprises a base 11 and a substrate 10. The base 11 is provided with the substrate 10 on one side of the upper end surface. A plurality of adsorption plates 13 are provided on the end surface of the substrate 10. A sliding seat 15 is slidably provided on one side of the adsorption plate 13. A slide plate 18 is slidably provided on the end surface of the sliding seat 15. A polishing head 22 is slidably provided on one side of the slide plate 18.

[0026] A water hose 21 is slidably arranged above the polishing head 22, and a plurality of water spray holes 31 are arranged on the bottom end face of the water hose 21. Spherical sleeves 20 are arranged at both ends of the water hose 21. The water hose 21 and the spherical sleeve 20 are both arranged above the polishing head 22, so that the supply of cutting fluid can be effectively completed. The spheres of the water hose 21 and the spherical sleeve 20 are both made of elastic shock-absorbing material. A spherical groove 25 is arranged on the spherical surface of the spherical sleeve 20, and a plurality of open grooves 24 are arranged outside the spherical groove 25. The plurality of open grooves 24 divide the spherical surface of the spherical sleeve 20 into multiple blocks.

[0027] When the front cover needs to be polished, the staff can place the front cover on one side of the multiple adsorption plates 13, and then open the adsorption plates 13. The multiple adsorption plates 13 can adsorb and fix the front cover. At this time, the front cover is in a vertical state as a whole. At this time, the sliding seat 15 moves downward, thereby driving the slide plate 18 and the polishing head 22 to move to the position outside the front cover that needs to be polished. At this time, the water hose 21 and the two spherical sleeves 20 can move toward the front cover. The spheres of 0 are all made of elastic shock-absorbing material, so as to clamp and fix the front hood. The grooves of spherical grooves 25 are formed on the outer spherical surfaces of the two spherical sleeves 20, which can better fit with the curved surface of the front hood, and the multiple open grooves 24 separate the spherical surface of the spherical sleeve 20 into multiple blocks. When the spherical grooves 25 contact the curved surface of the front hood, the single separated spherical sleeve 20 block can bend and deform outward according to the change of the curved surface at that location, so that it can fully fit with the curved surface of the front hood, completing efficient limiting and fixing processing.

[0028] When the spherical sleeve 20 is pressed against the end face of the front hood, the water hose 21 will bend and deform according to the curved surface of the front hood, so that the end face of the water hose 21 can be better pressed against the end face of the front hood. During the subsequent polishing process, the water hose 21 and the spherical sleeve 20 can absorb the vibration during polishing, so that the front hood can be polished stably and the quality of polishing can be improved. During this process, the cutting fluid for polishing will flow inside the water hose 21, and then the cutting fluid will be sprayed onto the curved surface of the front hood through the water spray hole 31, thereby improving the polishing effect. In this relationship, the water hose 21 and the spherical sleeve 20 are both arranged above the polishing head 22, so the supply of cutting fluid can be effectively completed.

[0029] After the front cover is clamped, the slide plate 18 will drive the polishing head 22 to move to various places on the curved surface of the front cover to complete the grinding and polishing process. The vertically placed front cover can allow waste chips and cutting fluid to flow better during grinding, which can effectively improve the polishing quality. In this relationship, the polishing head 22 is a prior art, and the specific grinding structure will not be elaborated on.

[0030] refer to Figure 5-6Two first push cylinders 16 are symmetrically arranged on the end surface of the sliding seat 15, and a spherical sleeve 20 is slidably arranged on the outside of the output end of the first push cylinder 16. A sliding hole 27 is arranged on one side of the spherical sleeve 20 on the output end of the first push cylinder 16, and a spring 28 is connected between the bottom of the sliding hole 27 and the spherical sleeve 20.

[0031] The output end of the first push cylinder 16 can push the spherical sleeve 20 and the water hose 21 to press on the curved surface of the front hood. In the process of the spherical sleeve 20 pressing on the end surface of the front hood, the spherical sleeve 20 will slide toward the sliding hole 27 due to pressure. At this time, the spring 28 in the sliding hole 27 will be subjected to force. When the spherical sleeve 20 is fully compressed, the spring 28 can help absorb certain vibrations, thereby improving the stability of the front hood during grinding and polishing.

[0032] refer to Figure 5 A rough surface pad 26 is provided at the center of the outer end surface of the spherical sleeve 20.

[0033] The rough surface pad 26 is made of hard metal material and is arranged at the center position of the spherical surface of the spherical sleeve 20. When the spherical surface of the spherical sleeve 20 is under pressure as a whole, the end surface of the rough surface pad 26 will contact the curved surface of the front hood, thereby forming a hard support point on the end surface of the front hood to improve the fixing effect.

[0034] refer to Figure 5 A plurality of elastic arc plates 23 are evenly arranged on the outer end surface of the water hose 21 along a straight line direction, and a plurality of convex strips 29 are arranged on the outer arc surface of each elastic arc plate 23 .

[0035] An elastic metal wire is arranged inside the elastic arc plate 23, so that the elastic arc plate 23 has a certain elastic supporting force and elastic deformation effect when it is in an arc-shaped state as a whole. When the water hose 21 gradually approaches the front hood, the outer arc surfaces of multiple elastic arc plates 23 will drive the convex strips 29 to press on the curved surface of the front hood. The elastic arc plate 23 can be elastically deformed in this process, so that it can better fit on the front hood and provide a certain elastic supporting pressure. In this relationship, the setting of the convex strips 29 can increase the contact friction, so that the curved surface of the front hood can effectively avoid slipping, deviation, vibration and the like during high-speed polishing, thereby effectively improving the polishing accuracy and effect.

[0036] refer to Figure 1 A recovery seat 12 is provided on the end surface of the base 11 below the substrate 10, and a filter plate is provided on the end surface of the recovery seat 12.

[0037] The front cover is polished in a vertical position as a whole. The cutting fluid and waste chips flowing downward during the polishing process will flow to the recovery seat 12. The filter plate in the recovery seat 12 will filter the waste chips outside, and then the cutting fluid will be recycled.

[0038] refer to Figure 1-4 A second linear drive 17 is arranged on the end surface of the sliding seat 15, and the second linear drive 17 is used to drive the slide plate 18 to move. A second push cylinder 19 is arranged on the end surface of the slide plate 18, and a polishing head 22 is connected to the output end of the second push cylinder 19.

[0039] The second linear drive 17 is a prior art and will not be elaborated in this article. The second linear drive 17 can drive the slide plate 18 to move back and forth on the end surface of the sliding seat 15, so that the grinding position can be adjusted laterally. The output end of the second push cylinder 19 can drive the polishing head 22 to adjust the grinding depth, so that the polishing thickness can be adjusted.

[0040] refer to Figure 2 A plurality of first linear drivers 14 are disposed on the end surface of the substrate 10 , and the first linear drivers 14 are used to drive the sliding seat 15 to move.

[0041] The first linear drive 14 is a prior art and will not be elaborated in detail in this article. The first linear drive 14 can drive the sliding seat 15 to move back and forth on the end surface of the substrate 10, so that the polishing position can be adjusted vertically. In conjunction with the slide plate 18, polishing can be completed at various positions on the curved surface of the front cover.
