It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0026] Please refer to Figures 1 - 6 , Figure 1 which is a partial exploded structural schematic diagram of the grinding device for processing seat tubes provided by an embodiment of the present utility model; Figure 2 which is a partial first three-dimensional structural schematic diagram of the grinding device for processing seat tubes provided by an embodiment of the present utility model; Figure 3 which is a partial second three-dimensional structural schematic diagram of the grinding device for processing seat tubes provided by an embodiment of the present utility model; Figure 4 is Figure 2 the enlarged view at A in Figure 5 is Figure 2 the enlarged view at B in Figure 6 is Figure 3Enlarged view at position C in []. The grinding device 1 for processing seat tubes of the present utility model includes a frame 11, a vertical grinding assembly 12, and a horizontal grinding assembly 13. The vertical grinding assembly 12 includes a first driving member 121, a first grinding frame 122, a first support frame 123, and a first grinding wheel 124. At least one first tensioning wheel 125 is provided on the first grinding frame 122, and at least two first tensioning wheels 125 are provided on the first support frame 123 in the vertical direction. The first grinding wheel 124 is mounted on at least three of the first tensioning wheels 125 and is in contact with the first support frame 123. The first driving member 121 is fixed to the frame 11 and is connected to one of the first tensioning wheels 125. The horizontal grinding assembly 13 includes a second driving member 131, a second support frame 133, a second grinding frame 132, and a second grinding wheel 134. An installation hole is formed in the frame 11, and the second grinding frame 132 is installed in the installation hole. At least one second tensioning wheel 135 is provided on the second grinding frame 132, and at least two first tensioning wheels 125 are provided on the second support frame 133 in the horizontal direction. The second grinding wheel 134 is mounted on at least three of the second tensioning wheels 135 and is in contact with the second support frame 133. The second driving member 131 is fixed to the frame 11 and is connected to one of the second tensioning wheels 135.

[0027] When grinding the seat tube, first place the seat tube on the frame 11 and push the seat tube in the direction of the vertical grinding assembly 12 and the horizontal grinding assembly 13, so that the vertical grinding assembly 12 grinds one side of the seat tube, and the horizontal grinding assembly 13 grinds the other side of the seat tube. During the grinding process, the seat tube can be rotated to enable the vertical grinding assembly 12 and the horizontal grinding assembly 13 to perform grinding operations on the entire outer surface of the seat tube. Since the vertical grinding assembly 12 and the horizontal grinding assembly 13 work simultaneously, when the seat tube is completely pushed from one side of the frame 11 to the other side, 360-degree dead-angle-free grinding of the outer surface of the seat tube can be achieved, improving the grinding efficiency and effect.

[0028] In the above embodiment, the seat tube is a round tube, so the seat tube can be rotated during the grinding process. When the seat tube is a square tube, the vertical grinding assembly 12 and the horizontal grinding assembly 13 can be used to grind two of the sides of the seat tube respectively. After the grinding is completed, the seat tube is flipped 180 degrees, and then the seat tube is placed on the frame 11 again and pushed for secondary grinding, so that 360-degree dead-angle-free grinding of the entire outer surface of the seat tube can be achieved, improving the grinding efficiency and effect.

[0029] In the above embodiment, when the vertical grinding assembly 12 grinds the seat tube, one of the first tension wheels 125 is driven to rotate by the first driving member 121, and the rotating first tension wheel 125 drives the first grinding wheel 124 to rotate. Thus, when the first grinding wheel 124 contacts the surface of the seat tube, the first grinding wheel 124 grinds the surface of the seat tube. During the grinding process, the first support frame 123 provides a supporting force for the seat tube to increase the friction between the first grinding wheel 124 and the seat tube and improve the grinding effect.

[0030] In the above embodiment, when the horizontal grinding assembly 13 grinds the seat tube, one of the second tension wheels 135 is driven to rotate by the second driving member 131, and the rotating second tension wheel 135 drives the second grinding wheel 134 to rotate. Thus, when the second grinding wheel 134 contacts the surface of the seat tube, the second grinding wheel 134 grinds the surface of the seat tube. During the grinding process, the second support frame 133 provides a supporting force for the seat tube to increase the friction between the second grinding wheel 134 and the seat tube and improve the grinding effect.

[0031] Among them, both the first driving member 121 and the second driving member 131 adopt motors, so that the first driving member 121 drives one of the first tension wheels 125 to rotate, and the second driving member 131 drives one of the second tension wheels 135 to rotate.

[0032] In the embodiment of the present utility model, two groups of the vertical grinding assemblies 12 are provided, and the two groups of the vertical grinding assemblies 12 are symmetrically arranged to grind the left and right sides of the seat tube.

[0033] By symmetrically arranging two groups of vertical grinding assemblies 12 on both sides of the seat tube, when the seat tube passes through the frame 11, the vertical grinding assemblies 12 on both sides work simultaneously to uniformly grind the left and right sides of the seat tube, ensuring the consistency of grinding on both sides of the seat tube, avoiding the problems of excessive or insufficient grinding on one side, improving the uniformity of grinding and the product quality, and at the same time improving the grinding efficiency of the seat tube.

[0034] In an embodiment of the present utility model, the grinding device 1 further includes a movable grinding assembly 14. The movable grinding assembly 14 includes a third driving member 141, a third support frame 143, a third grinding frame 142, and a third grinding wheel 144. Support plates are symmetrically arranged on the frame 11 on both sides of the mounting hole. The third grinding frame 142 is slidably connected between the two support plates. At least one third tensioning wheel 145 is arranged on the second grinding frame 132. At least two third tensioning wheels 145 are arranged on the third support frame 143 in the horizontal direction. The third grinding wheel 144 is mounted on at least three of the third tensioning wheels 145 and is in contact with the third support frame 143. The third driving member 141 is fixed to the support plate and is connected to one of the third tensioning wheels 145.

[0035] When the movable grinding assembly 14 grinds the seat tube, the third driving member 141 drives one of the third tensioning wheels 145 to rotate, and the rotating third tensioning wheel 145 drives the third grinding wheel 144 to rotate. Thus, when the third grinding wheel 144 contacts the surface of the seat tube, the third grinding wheel 144 grinds the surface of the seat tube. During the grinding process, the third support frame 143 provides a supporting force for the seat tube to increase the friction between the second grinding wheel 134 and the seat tube and improve the grinding effect.

[0036] In an embodiment of the present utility model, the movable grinding assembly 14 further includes a vertical driving member 145. The vertical driving member 145 is fixed to the top of the frame 11 and is connected to the third grinding frame 142 to drive the movable grinding assembly 14 to lift along the support plate.

[0037] By installing the vertical driving member 145 on the top of the frame 11 and connecting the vertical driving member 145 to the third grinding frame 142, it is convenient to adjust the height of the third grinding frame 142 through the vertical driving member 145, so that the third grinding frame 142 moves vertically along the support plate to grind seat tubes of different heights, further improving the grinding efficiency and flexibility of the seat tube. In the above embodiment, the vertical driving member 145 can adopt a hydraulic or electric push rod to achieve smooth and precise vertical movement.

[0038] In an embodiment of the present utility model, a horizontally slidable first sliding rod 126 is arranged on the grinding frame. The first support frame 123 is slidably connected to the first grinding frame 122 through the first sliding rod 126.

[0039] By arranging a horizontally slidable first sliding rod 126 on the first grinding frame 122, the first support frame 123 is slidably connected to the first grinding frame 122 through the first sliding rod 126. Thus, during the grinding process, the operator can adjust the horizontal position of the first support frame 123 according to the specific position of the seat tube, ensuring the contact between the grinding wheel and the surface of the seat tube, thereby realizing the control of the grinding force on the seat tube and improving the grinding effect on the seat tube.

[0040] In the above embodiment, scales or positioning marks can be arranged on the first sliding rod 126 to help the operator accurately control the position of the first support frame 123 and achieve precise grinding.

[0041] In an embodiment of the present utility model, two first tension wheels 125 are arranged on the first grinding frame 122, and an adjusting rod 127 is hinged on the first grinding frame 122. Among them, one of the first tension wheels 125 is rotatably connected to the grinding frame, and one of the first tension wheels 125 is rotatably connected to the adjusting rod 127.

[0042] By arranging a first tension wheel 125 on the first grinding frame 122 and a tension wheel on the adjusting rod 127, during the grinding process, it is convenient for the operator to adjust the tension degree of the tension wheel by rotating the adjusting rod 127, thereby changing the pressure of the grinding wheel on the seat tube, and further realizing the fine control of the grinding pressure and improving the grinding quality and efficiency.

[0043] In an embodiment of the present utility model, a spring 128 is arranged on the first grinding frame 122. Two ends of the spring 128 respectively abut against the adjusting rod 127 and the first grinding frame 122 to provide an elastic movement margin for the adjusting rod 127 under the elastic force of the spring 128, so as to use seat tubes of different thicknesses and grind them, improving the grinding flexibility.

[0044] In an embodiment of the present utility model, a protective plate 111 and a protective door 112 are arranged on the machine frame 11. The protective plate 111 and the protective door 112 jointly surround the horizontal grinding assembly 13 and the vertical grinding assembly 12 to protect the operator under the action of the protective plate 111 and the protective door 112, avoiding the operator from being injured by flying debris and improving the work safety.

[0045] In an embodiment of the present utility model, the protective plate 111 is a transparent protective plate 111, and the protective door 112 is a transparent protective door 112, so that the operator can observe the grinding process in a safe environment under the action of the transparent protective plate 111 and the transparent protective door 112.

[0046] In an embodiment of the present utility model, the protective doors 112 are symmetrically arranged on opposite sides of the frame 11. A feeding port is formed in one of the protective doors 112, and a discharging port is formed in the other protective door 112. The feeding port and the discharging port are collinearly arranged, so that an operator can put the seat tube into the frame 11 from the feeding port, and during the process of pushing the seat tube, the seat tube is pushed out from the discharging port, thereby realizing the grinding process of the seat tube. The protective doors 112 do not need to be opened during the grinding operation, further improving the safety of the grinding operation.
