Description

Technical Field

[0001] The utility model relates to the technical field of automobile polishing, in particular to a material grinding and polishing device. Background Art

[0002] After machining automotive exterior parts, they need to be polished using a polishing machine to enhance their aesthetics. Currently, before polishing automotive exterior parts, a suitable amount of polishing fluid is applied to the bottom of the polishing machine's sponge polishing pad to improve the polishing effect. However, this is not usually done beforehand. Excessive polishing fluid not only wastes the fluid but also easily affects the contact between the polishing pad and the part surface, reducing polishing efficiency. Therefore, only a small amount of polishing fluid is applied to the bottom of the polishing pad before polishing. When the part polishing area is large, the polishing fluid needs to be replenished midway, which is cumbersome and reduces polishing efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention proposes a material grinding and polishing device to solve the above problems.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] The utility model provides a material grinding and polishing device, comprising a polishing machine body, a handle provided on one side of the polishing machine body and a rotating shaft installed at the bottom of the polishing machine body, a polishing disc installed at the bottom end of the rotating shaft, and further comprising:

[0006] The liquid replenishing assembly includes a liquid storage tank and a liquid discharge head. The liquid storage tank is installed on the top of the polishing machine body and a piston column is slidably inserted at one end of the liquid storage tank.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1-5 As shown, the present embodiment provides a material grinding and polishing device, including a polishing machine body 1, a handle 11 is provided on one side, the end of the handle 11 is connected to a power cord, a motor is installed inside the polishing machine body 1, a rotating shaft 12 is installed at the bottom of the polishing machine body 1, the rotating shaft 12 is connected to the internal motor, and a polishing disc 13 is installed at the bottom of the rotating shaft 12. The polishing machine body 1 is a prior art product, so its specific details are not repeated in detail. The material grinding and polishing device also includes a fluid replenishing component 2 and a control component 3.

[0029] The liquid replenishing component 2 includes a liquid storage tank 21 and a liquid discharge head 22. The liquid storage tank 21 is used to store polishing liquid. The liquid storage tank 21 is installed on the top of the polishing machine body 1 and a piston column 211 is slidably inserted at one end thereof. One end of the piston column 211 is located inside the liquid storage tank 21 and is provided with a piston plate that fits tightly with the inner wall of the liquid storage tank 21. The outer end of the piston column 211 is provided with a stop plate 212. The liquid discharge head 22 is installed below the polishing machine body 1 through a support 221 and is located on the outside of the polishing disk 13, and the open end of the liquid discharge head 22 faces the outside of the polishing disk 13. A conduit 23 is connected between the liquid discharge head 22 and the end of the liquid storage tank 21 away from the piston column 211. By squeezing the piston column 211 into the liquid storage tank 21, the polishing liquid can be pushed to the outside of the liquid discharge head 22 through the conduit 23.

[0030] In order to prevent the liquid discharge head 22 from scraping the surface of the component, preferably, the liquid discharge head 22 can be made of rubber.

[0031] Furthermore, a liquid filling port is opened on the side of the top of the liquid storage tank 21 away from the piston column 211, and a sealing cover 213 is detachably connected to the outside of the liquid filling port. The connection method between the sealing cover 213 and the liquid filling port can be a conventional connection method such as piston plug-in, threaded connection, etc., which is convenient for replenishing polishing liquid into the liquid storage tank 21.

[0032] like Figure 1-Figure 3 As shown, the control component 3 includes a swivel seat 31 and a control rod 32. The swivel seat 31 is installed on the top of the polishing machine body 1 and is located on the side of the abutment 212 away from the liquid storage tank 21. A ball groove 311 is provided at the top of the swivel seat 31, and a rotating ball 321 is provided at the bottom end of the control rod 32. The rotating ball 321 can be movably embedded in the ball groove 311 so that the control rod 32 can rotate freely based on the ball groove 311, and an abutment block 322 is provided on the control rod 32, which can abut against the side of the abutment 212 away from the liquid storage tank 21.

[0033] When using this device to grind and polish the surface of a part, the operator can use his finger to push the control rod 32 toward the liquid reservoir 21 to deflect the control rod 32 toward the liquid reservoir 21, and then push the piston column 211 into the liquid reservoir 21, so that the polishing liquid is discharged from the liquid outlet head 22 through the conduit 23, and the polishing liquid will drip to the side of the polishing disk 13. The operator can move the polishing disk 13 toward the place where the polishing liquid drips to replenish the polishing liquid to the bottom of the polishing disk 13. In this way, the operator can continuously grind and polish a large area of the part surface and replenish the polishing liquid at any time, saving the time of replenishing the polishing liquid in the middle and improving the polishing efficiency.

[0034] In one embodiment, a rotating seat 31 is mounted at the top center of the polishing machine body 1, and multiple fluid replenishing assemblies 2 are arranged around the rotating seat 31 on the polishing machine body 1, with the side of each abutment 212 away from its corresponding fluid storage tank 21 facing the abutment block 322. Each fluid outlet head 22 surrounds the outer side of the polishing disc 13. During use, the operator can push the control rod 32 in the corresponding direction according to the movement direction of the polishing disc 13 to squeeze the piston column 211 in the corresponding direction, so that the polishing liquid can drip onto the movement path of the polishing disc 13. This helps to keep the polishing disc 13 always in contact with the surface of the part during the polishing process, eliminating the need to pick up the device and reposition it, thereby improving polishing efficiency.

[0035] Preferably, a return spring 323 is connected between the abutment block 322 and the swivel seat 31. The return spring 323 is initially in an upright state to provide elastic force to keep the control rod 32 upright on the top of the polishing machine body 1. Whenever the operator pushes the control rod 32 to deviate, the return spring 323 can bounce the control rod 32 back to the top center of the polishing machine body 1 so that it can be reset for the next shift.

[0036] like Figure 4 As shown, in one embodiment, the bottom edge of the polishing disk 13 is arc-shaped. When the polishing disk 13 rotates for grinding and polishing, the polishing liquid dripping onto the surface of the part in the middle can be squeezed into the bottom of the polishing disk 13 along the angle between the arc-shaped surface of the bottom edge of the polishing disk 13 and the surface of the part, preventing the polishing liquid from adhering to the side wall of the polishing disk 13, thereby improving the utilization rate of the polishing liquid. Furthermore, a plurality of arc-shaped grooves 131 are evenly distributed on the bottom circumference of the polishing disk 13, and one end of each arc-shaped groove 131 faces the outside of the polishing disk 13 and the other end converges toward the center of the polishing disk 13. There can be a certain gap between the arc-shaped groove 131 and the surface of the part, so that the high-speed rotating polishing disk 13 can deliver the polishing liquid into its bottom center, so that the polishing liquid is evenly distributed on the bottom side of the polishing disk 13.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
