[0004] For example, the utility model with application number 202210776990.2 discloses a tire grinding device, in which a clamping device is used to fix the tire in the axial direction and drive the tire to rotate around the axial direction. A tire grinding system is also provided in the frame for grinding the surface of the tire. When the tire needs to be ground, the tire is fixed in the frame by the clamping device and the tire is driven to rotate around its central axis. The tire grinding system is started to grind the tire. However, similar to the tire grinding device in the above-mentioned document, its clamping device has relatively limited flexibility during use, so that when encountering tires of different diameters, its structural clamping ability is relatively limited.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a tire grinding device is proposed. Utility Model Content

[0008] Furthermore, the adjustment grooves are arranged in a concentric circular array with the adjustment disk as the center, and the limit frame is arranged in an "L"-shaped structure.

[0009] Furthermore, the lifting frame is vertically installed on the bottom of the adjustment platform in a front-to-back symmetrical manner, and the rotating bracket and the lifting frame are located on the same central axis.

[0010] Furthermore, the adjustment platform includes a stabilizing platform, a slide rail, a servo motor, a guide rail and a lead screw. Slide rails are provided on both sides of the left and right sides of the stabilizing platform, and a servo motor is installed at the end of the stabilizing platform away from the fixed frame. A guide rail is installed in the middle section of the top of the stabilizing platform, and a lead screw is horizontally arranged in the middle of the guide rail.

[0011] Furthermore, one end of the lead screw is connected to the power output end of the servo motor through a coupling, and the stabilizing platform and the slide rail are fixedly connected.

[0012] Furthermore, the grinder includes a DC motor, a movable seat, a connecting rod and a grinding wheel. The bottom of the DC motor is connected to the movable seat, and the power output end on one side of the DC motor is installed with a connecting rod through a coupling, and the grinding wheel is installed at the end of the connecting rod away from the movable seat.

[0013] Furthermore, the baffle includes a protective plate, a stabilizing frame and a sliding block. The left and right ends of the bottom of the protective plate are connected to the stabilizing frame, and the bottom of the stabilizing frame is connected to the sliding block.

[0014] Furthermore, the slider is slidably connected to the slide rail, and the movable seat is slidably connected and threadedly connected to the guide rail and the lead screw respectively.

[0015] The utility model provides a tire grinding device, which has the following beneficial effects:

[0016] 1. The utility model provides a fixing frame at the top of the rotating bracket, wherein a ring array is adopted on the surface of the adjusting disk, and a concentric circle structure is adopted at the same time, and a plurality of adjusting slots are opened, which are matched with a plurality of adjusting bolts for installing the limit frames. The adjusting bolts are passed through the adjusting slots, and then the plurality of limit frames and the adjusting disk are connected and fixed to each other, so that an annular clamping structure can be formed around the tire. The use of the above structure can provide effective and flexible adjustability for the entire device to the greatest extent. Within a certain range, relative adjustment can be made according to the diameter and width of the tire, thereby ensuring the stability of the tire's own structure during processing and avoiding processing failures caused by structural loosening.

[0017] 2. The utility model provides a baffle in the middle of the grinder, wherein the protective plate is vertically inserted in the middle of the DC motor and is fixed to the slider through a stabilizing frame. When the grinder moves back and forth in the horizontal direction, the entire baffle can be moved horizontally along the surface of the slide rail by means of the slider. At the same time, the protective plate itself is made of a transparent material. By using the above structure, on the one hand, it can effectively prevent the unnecessary impact of waste chips splashing on the operator when the grinder is grinding the inner wall of the tire. On the other hand, it can provide effective structural shielding while avoiding visual interference, so that the operator can confirm the processing status of the tire in real time.

[0018] 3. The utility model uses a lifting frame and an adjusting platform in combination. Under the structural extension and contraction of the lifting frame, the adjusting platform and the grinder on the top can be simultaneously raised and lowered within a certain range in the vertical direction. When the servo motor is in operation, it drives the lead screw connected thereto to rotate horizontally, so that the movable seat can simultaneously translate horizontally along the surface of the guide rail and the lead screw. By utilizing the combined use of the above structures, the grinder can be flexibly adjusted in structure as needed to better provide grinding processing for the inner wall of the tire, thereby ensuring the processing quality while ensuring the flexibility between the various structures of the entire device.

The fixed frame 3 includes an adjusting disk 301, an adjusting slot 302, an adjusting bolt 303 and a limit frame 304. The surface of the adjusting disk 301 is An adjusting groove 302 is provided on the surface, and an adjusting bolt 303 is passed through the middle of the adjusting groove 302, and a limiting frame 304 is installed at one end of the adjusting bolt 303 close to the grinder 6. The adjusting groove 302 is arranged in a concentric ring array with the adjusting disk 301 as the center, and the limiting frame 304 is arranged in an "L"-shaped structure. The adjusting bolt 303 is passed through the inside of the adjusting groove 302, and then several limiting frames 304 are connected and fixed to the adjusting disk 301, so that a ring-shaped clamping structure can be formed around the tire.

[0027] like Figures 1 to 5 As shown, the lifting frame 4 is vertically installed at the bottom of the adjustment platform 5 symmetrically front and back, and the rotating bracket 2 and the lifting frame 4 are at the same central axis position. The adjustment platform 5 includes a stabilizing platform 501, a slide rail 502, a servo motor 503, a guide rail 504 and a screw 505. Slide rails 502 are provided on the left and right sides of the stabilizing platform 501, and the servo motor 503 is installed at the end of the stabilizing platform 501 away from the fixed frame 3. In addition, a guide rail 504 is installed in the middle section of the top of the stabilizing platform 501, and a screw 505 is horizontally installed in the middle of the guide rail 504. One end of the screw 505 is connected to the power output end of the servo motor 503 through a coupling, and the stabilizing platform 501 and the slide rail 502 are fixedly connected. When the grinder 6 moves back and forth in the horizontal direction, the entire baffle 7 can use the slider 703 to move horizontally along the surface of the slide rail 502 at the same time. At the same time, the protective plate 701 itself is made of transparent material. While serving as a structural shield, it can also facilitate the operator to observe the status of the tire during processing.

[0028] like Figures 1 to 5As shown, the grinder 6 includes a DC motor 601, a movable seat 602, a connecting rod 603 and a grinding wheel 604. The bottom of the DC motor 601 is connected to the movable seat 602, and the power output end of one side of the DC motor 601 is installed with a connecting rod 603 through a coupling, and the end of the connecting rod 603 away from the movable seat 602 is installed with a grinding wheel 604. The baffle 7 includes a protective plate 701, a stabilizing frame 702 and a slider 703. The left and right ends of the bottom of the protective plate 701 are connected to the stabilizing frame 702, and the bottom of the stabilizing frame 702 is connected to the slider. 703, the slider 703 is in sliding connection with the slide rail 502, and the movable seat 602 is in sliding connection and threaded connection with the guide rail 504 and the lead screw 505 respectively. Under the structural extension and contraction of the lifting frame 4, the adjustment platform 5 and the grinder 6 on the top thereof can be simultaneously adjusted up and down within a certain range in the vertical direction. When the servo motor 503 is in operation, it drives the lead screw 505 connected thereto to rotate horizontally, so that the movable seat 602 can simultaneously translate in the horizontal direction along the surface of the guide rail 504 and the lead screw 505.

[0029] In summary, if Figures 1 to 5 As shown, when using the tire grinding device, first place the tire in the middle of the fixing frame 3. During this process, according to the diameter of the tire, select the appropriate number of adjusting bolts 303 and limiting frames 304, and select the adjusting groove 302 with a structure that matches the tire diameter. Then, fix the adjusting bolts 303 connected to the limiting frames 304 inside the adjusting groove 302. Once installed, the tire is fixed to the side of the adjusting plate 301.

[0030] Then, the lifting frame 4 is extended and retracted to adjust the adjustment platform 5 mounted on the top thereof in the vertical direction. At the same time, the servo motor 503 mounted on one side of the stabilizing platform 501 starts to operate synchronously, driving the lead screw 505 connected to the power output end thereof to rotate axially in the horizontal direction, thereby driving the entire grinder 6 connected to the lead screw 505 via the moving base 602 to move horizontally toward one side of the tire until the grinding wheel 604 mounted on one end of the connecting rod 603 contacts the inner wall of the tire.

[0031] While the entire grinder 6 is moving horizontally, the protective plate 701 inserted on the surface of the DC motor 601 will use the slider 703 at the bottom of the stabilizing frame 702 to slide synchronously along the surface of the slide rail 502 installed on the side of the stabilizing table 501. Then, driven by the DC motor 601, the connecting rod 603 connected thereto will drive the grinding wheel 604 to rotate at high speed, and at the same time rotate the fixing frame 3 on the top of the rotating bracket 2, so that the fixed tire will rotate slowly and uniformly with the fixing frame 3 as the center of the circle, so that the grinding wheel 604 grinds the inner wall surface of the tire.
