Specific embodiments
[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a single-sided grinding machine with a protection structure, including a workbench 1, a motor 2 is fixedly installed on the left side of the workbench 1, which can drive the rotation of the rotating shaft, so that the transmission wheel 3 rotates. The outer wall of the rotating shaft at the output end of the motor 2 is fixedly installed with a transmission wheel 3, which can drive the abrasive belt 4 to rotate. The outer wall of the transmission wheel 3 is drivingly connected with an abrasive belt 4, which can grind iron materials. A clamping device 5 is arranged on the top of the workbench 1, which can perform grinding without manual pushing. A shielding device 6 is arranged on the top of the workbench 1, which can prevent the splashing of sparks.
[0023] Specifically, the clamping device 5 includes: a sliding block 51, a placement plate 52, a fixed block 53, a sliding rod 54, a telescopic spring 55, a push plate 56, a rotating rod 57, a hollow rod 58, a bolt 59, a chute 510, and a clamping plate 511. The sliding block 51 is slidably mounted on the front surface of the workbench 1 and can drive the fixed block 53 to move. The back surface of the sliding block 51 is fixedly mounted with the placement plate 52, which facilitates the placement of iron materials and the installation of the fixed block 53. The front surface of the placement plate 52 is fixedly mounted with the fixed block 53, which facilitates the sliding of the sliding rod 54 and the installation of the telescopic spring 55. The sliding rod 54 is slidably mounted at the through-hole of the fixed block 53 and can drive the push plate 56 to move back and forth. The telescopic spring 55 is fixedly mounted on the front surface of the fixed block 53 and can cause it to reset after pulling the sliding rod 54. The end of the telescopic spring 55 away from the fixed block 53 is fixedly mounted on the back surface of the convex block on the front of the sliding rod 54 for fixation. The back surface of the sliding rod 54 is fixedly mounted with the push plate 56, which can push the grinding material towards the abrasive belt 4. The top of the push plate 56 is hinged with the rotating rod 57, which facilitates driving the rotation of the hollow rod 58 and can also push. The outer wall of the rotating rod 57 is slidably mounted with the hollow rod 58, which facilitates the contraction of the rotating rod 57. The bolt 59 is threadedly connected to the through-hole at the top of the hollow rod 58 and can fix the hollow rod 58 and the rotating rod 57. The end of the hollow rod 58 away from the rotating rod 57 is hinged with the clamping plate 511, which can clamp both sides of the grinding material. The chute 510 is opened at the top of the placement plate 52 to facilitate the sliding of the clamping plate 511. The rotating rod 57, the hollow rod 58, and the clamping plate 511 are symmetrically distributed on the left and right sides of the push plate 56 with respect to the axis of symmetry of the side center of the push plate 56, enabling the clamping of the grinding material. The bottom of the clamping plate 511 is slidably mounted inside the chute 510.
[0024] Specifically, the shielding device 6 includes: an L-shaped plate 61, a connecting rod 62, a return spring 63, and a slider 64. The L-shaped plate 61 is hinged at the top of the placement plate 52 and can protect the part being ground to prevent the splashing of sparks. The front of the hinge rod at the hinge of the L-shaped plate 61 is hinged with the connecting rod 62, which can push the hinge of the L-shaped plate 61 to cause the L-shaped plate 61 to rotate. The return spring 63 is fixedly mounted on the left side of the chute 510 and can drive the slider 64 to reset. The end of the return spring 63 away from the chute 510 is fixedly mounted with the slider 64, which can be squeezed by the clamping plate 511 to drive the connecting rod 62 to push the L-shaped plate 61 to rotate and can also squeeze the return spring 63. The end of the connecting rod 62 away from the L-shaped plate 61 is hinged to the front of the slider 64.
[0025] Working principle: When the grinding belt 4 rotates when the motor 2 starts, place the iron material to be polished on the placement plate 52. First, pull out the sliding rod 54 from the fixed block 53 to stretch the telescopic spring 55, pull the push plate 56 backward, which can drive the rotating rod 57 to drive the hollow rod 58 to push the clamping plate 511 to move outward, place the iron material on the placement plate 52, release the sliding rod 54, and the telescopic spring 55 resets to make the clamping plate 511 clamp the workpiece to prevent deviation during grinding. When the clamping space is insufficient, the bolt 59 can be rotated, the hollow rod 58 can be pulled out, and then the bolt 59 can be tightened, so that it can be lengthened and the clamping space can be increased. When the sliding rod 54 is released, the telescopic spring 55 will reset the push plate 56, and the force of the push plate 56 resetting is greater than the force of the clamping plate 511 clamping, so that the iron material is pushed into the grinding belt 4. The sliding block 51 can also be moved to move the placement plate 52, and the workpiece can be better polished, which can prevent the operator from manually polishing, prevent the hand from being scalded, and prevent the sparks from splashing onto the hand.
[0026] By pulling out the sliding rod 54 as described above, the clamping plate 511 can move to both sides. When moving to the leftmost side, the clamping plate 511 will push the slider 64, so that the slider 64 slides in the chute 510, and the return spring 63 is compressed. The connecting rod 62 will make the hinge rod at the hinge of the L-shaped plate 61 rotate, so that the L-shaped plate 61 is flipped. On the contrary, when the clamping plate 511 clamps, the slider 64 is not squeezed, and the L-shaped plate 61 will be flipped under the action of the reset of the return spring 63, which can prevent the sparks from splashing during grinding and causing the flammable substances to catch fire.
[0027] The above generally describes the present invention in detail, but on the basis of the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
