Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, and in particular relates to a production grinding device. Background Technology

[0002] The raw material for coiled rebar is steel billet, such as square or rectangular billet. After being heated to 1100-1250℃ in a furnace, it enters a rolling mill for multi-pass rolling. During the rolling process, the steel billet is gradually rolled into a bar with a smaller diameter. At this point, the bar is straight. After being coiled into a disc shape, the surface of the coiled rebar is usually polished to remove oxide scale, burrs, flash, unevenness, and other processing defects formed during the rolling process, so as to avoid affecting the bond strength between the steel reinforcement and the concrete.

[0003] Existing screw grinding devices suffer from low automation levels and excessive reliance on manual feeding and grinding adjustments, resulting in low production efficiency. Furthermore, since the grinding discs are consumables, disassembly requires additional tools, further increasing downtime and impacting production schedules. Therefore, we offer a production grinding device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8This utility model relates to a production grinding device, comprising an operating table 1; two feeding components are symmetrically fixed on the upper surface of the operating table 1, and a grinding component connected to the upper surface of the operating table 1 is fixedly disposed between the two feeding components; the grinding component includes a second motor 3, the output end of the second motor 3 is fixedly connected to a connecting shaft 302, a grinding disc 301 is snapped onto the outer wall of the connecting shaft 302, and a quick-release assembly is disposed between the grinding disc 301 and the connecting shaft 302. The quick-release assembly includes a vertical groove 304 and an arc groove 305 formed on the outer wall of the connecting shaft 302 and communicating with each other; a fixing block 306 that cooperates with the vertical groove 304 is fixedly connected to the middle of the grinding disc 301; a limiting ring 303 that cooperates with the grinding disc 301 is sleeved on the outer wall of the connecting shaft 302; a limiting block 307 that cooperates with the arc groove 305 is fixedly connected to the inner wall of the limiting ring 303; a limiting groove 314 is formed on the outer wall of the arc groove 305; and the inner sliding surface of the limiting block 307 is... The limit rod 309 is provided to cooperate with the limit groove 314. The limit block 307 has a movable cavity 312 and a sliding groove 308 that are interconnected. Two limit protrusions 310 that cooperate with the sliding groove 308 are symmetrically fixed on the outer wall of the limit rod 309. A circular disk 311 is fixedly connected to the outer wall of the limit rod 309. A spring 313 fixedly connected to one side of the circular disk 311 is sleeved on the outer wall of the limit rod 309. One end of the limit rod 309 passes through the limit block 307.

[0028] When grinding of the coiled screw is required, the coiled screw is passed through the grinding assembly, which limits and fixes the screw. Motor 2 (specifically, a servo motor) is started to drive the grinding disc 301 to rotate and grind the surface of the coiled screw. When the grinding disc 301 is worn and needs replacement, the limiting rod 309 is pulled to disengage from the limiting groove 314 on the surface of the arc-shaped groove 305. The limiting protrusion 310 on the outer wall of the limiting rod 309 moves along the sliding groove 308 inside the limiting block 307 to the movable cavity 312 inside the limiting block 307. During the movement of 09, the circular disc 311 on the outer wall compresses the spring 313, causing the spring 313 to generate elastic potential energy. At this time, 309 is rotated 90 degrees, and the limiting protrusion 310 on the outer wall of the limiting rod 309 is stuck in the movable cavity 312. The sliding groove 308 is connected to the movable cavity 312. The limiting ring 303 is rotated to the vertical groove 304 and moved out. Then the grinding disc 301 is removed along the limiting groove 314. At this time, the grinding disc 301 is quickly disassembled. When installing the grinding disc 301, the above steps are repeated to complete the installation.

[0029] Please see Figure 1 and Figure 4The feeding assembly includes a support plate 2, an upper roller 202 rotatably mounted on the inner wall of the support plate 2, a U-shaped plate 204 slidably connected inside the support plate 2, a screw 206 threadedly connected to the U-shaped plate 204 in the middle of the support plate 2, a rotating wheel 205 fixedly connected to the outer wall of the screw 206, a motor 201 fixedly connected to the upper roller 202 on the outer wall of the support plate 2, and a lower roller 203 rotatably connected inside the U-shaped plate 204 to cooperate with the upper roller 202.

[0030] The rotating screw 206 drives the U-shaped plate 204 and the lower roller 203 to descend and cooperate with the upper roller 202 to clamp and fix the coiled screw. The external power supply drives the motor 201 to rotate the upper roller 202. The motor 201 specifically refers to the servo motor. The motor 201 drives the upper roller 202 to rotate, thereby driving the coiled screw on the upper roller 202 to move and realize automatic feeding and grinding.

[0031] Please see Figure 2 Two fixed plates 4 are symmetrically fixed on the upper surface of the operating table 1, and two rotating rollers 5 that cooperate with the grinding disc 301 are rotatably arranged between the two fixed plates 4.

[0032] When the grinding disc 301 rotates to grind the screw, the screw rotates on the roller 5 under the drive of the grinding disc 301, thereby achieving comprehensive grinding of the outer surface of the screw and avoiding grinding dead corners.

[0033] The operation process of this embodiment is as follows: When grinding of the coiled screw is required, the coiled screw is passed through the grinding assembly. The rotating screw 206 drives the U-shaped plate 204 and the lower roller 203 to descend and cooperate with the upper roller 202 to clamp and fix the coiled screw. The external power supply drives the first motor 201 to drive the upper roller 202 to rotate. The first motor 201 specifically refers to a servo motor. The first motor 201 drives the upper roller 202 to rotate, thereby driving the coiled screw on the upper roller 202 to move, realizing automatic feeding and grinding. The second motor 3 drives the grinding disc 301 to rotate to grind the surface of the coiled screw. The second motor 3 specifically refers to a servo motor. When the grinding disc 301 is worn and needs to be replaced, the limit rod 309 is pulled to disengage it from the limit groove on the surface of the arc groove 305. 314. The limiting protrusion 310 on the outer wall of the limiting rod 309 moves along the sliding groove 308 inside the limiting block 307 to the movable cavity 312 inside the limiting block 307. During the movement of the limiting rod 309, the circular disc 311 on the outer wall compresses the spring 313, causing the spring 313 to generate elastic potential energy. At this time, 309 is rotated 90 degrees, and the limiting protrusion 310 on the outer wall of the limiting rod 309 is stuck in the movable cavity 312. The sliding groove 308 and the movable cavity 312 are connected to each other. The limiting ring 303 is rotated to the vertical groove 304 and moved out. Then the grinding disc 301 is removed along the limiting groove 314. At this time, the grinding disc 301 is quickly disassembled. When installing the grinding disc 301, the above steps are repeated to complete the quick installation.
