[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It comprises a first grinding wheel 3 and a second grinding wheel 4, wherein the first grinding wheel 3 and the second grinding wheel 4 are located on the same axis, are spaced from each other and are arranged with their end faces facing each other;

[0034] At least one of the first grinding wheel 3 and the second grinding wheel 4 is a movable structure, and the movable structure is specifically movable along its own axis direction to adjust the distance between the two grinding wheels; Figure 1 As shown, the first grinding wheel 3 is driven to rotate by the first motor 100, and the second grinding wheel 4 is driven to rotate by the second motor 7, wherein the second grinding wheel 4 is a movable structure, specifically, a sliding table 9 is installed at the bottom of the second motor 7, and the sliding table 9 is slidably connected to the frame 12, and a linear drive source is used to drive the sliding table 9 to slide back and forth in the horizontal direction. During specific installation, the device body also includes a frame 12, and the first grinding wheel 3, the second grinding wheel 4 and the driving unit for the two grinding wheels are installed above the frame 12, and a feeding channel is reserved after the device outer shell is encapsulated. A slide rail 10 is arranged on the upper table of the frame 12, and the sliding table 9 is slidably connected to the slide rail 10, and a brake assembly is arranged at the bottom of the sliding table 9, which is composed of multiple groups of electromagnets. The brake assembly is electrically closed in the working state and fixedly clamped on the slide rail 10, so that the position of the sliding table 9 remains stable.

[0035] The space between the two grinding wheels forms a feeding channel, and a feeding unit is arranged on the feeding channel. The feeding unit includes a workpiece storage bin 5 and a pushing assembly 2;

[0036] Reference Figure 3 As shown, the push assembly 2 is vertically installed above the second grinding wheel 4, and the push assembly 2 includes a mounting frame 23, a push cylinder 22 is fixedly installed on the top of the mounting frame 23, and a push plate 24 is connected to the output end of the push cylinder 22;

[0037] The workpiece storage bin 5 is a trough-type structure, and a through opening is provided at the front end of the workpiece storage bin 5 near the pushing component. A clamping component is provided in the workpiece storage bin 5 for clamping the workpieces stacked in sequence against the end wall on one side of the through opening, and the workpiece at the front end is pressed into the feeding channel through the through opening by the pushing component.

[0038] The push assembly 2 and the workpiece storage bin 5 are installed together on the base frame 6, and the base frame 6 is installed on the upper bracket where the second motor 7 is located. The base frame 6 is slidably connected with the upper bracket, and a linear drive source is used to control the base frame 6 to slide back and forth in the horizontal direction. Figure 1As shown, the linear drive source for controlling the base frame 6 is a hand-cranked screw 8, the optical axis end of the hand-cranked screw 8 is rotatably connected to the upper bracket, the threaded shaft section of the hand-cranked screw 8 is threadedly connected to the base frame 6, and the crank wheel of the hand-cranked screw 8 extends to the outside of the device for easy manual operation. Since the thickness of the grinding wheel will decrease during grinding, it is necessary to regularly adjust the position of the push assembly 2 and the workpiece storage bin 5. The hand-cranked screw has a relatively high precision and is more suitable for adjustment in this scenario, so that the workpiece can dock with the grinding wheel during feeding.

[0039] The feeding unit is configured to push the workpieces stored in the workpiece storage bin 5 into the feeding channel in sequence through the execution of the pushing assembly 2, so that the two side surfaces of the workpieces are opposite to the outer end surfaces of the two grinding wheels in the feeding channel; Figure 1 As shown, the two circular side surfaces of the workpiece are directly located between the two circular outer end surfaces of the grinding wheel, and the grinding operation is directly performed, which will have higher uniformity and grinding efficiency. Each time the material is pushed, the workpiece being ground will be pushed out, achieving uninterrupted grinding operations.

The limit plates 21 are fixedly installed at the bottom of the pushing component 2; the limit plates 21 are arranged at intervals along the pushing direction of the pushing component 2, and the workpiece is pushed between the limit plates 21 by the pushing component 2, thereby being limited;

The discharge channel 14 is connected to the discharge belt 1, and the discharge belt 1 outputs the polished workpiece to the outside of the device. The discharge belt 1 is installed at the bottom of the frame 12 and is also encapsulated by the outer shell. The output end of the discharge belt 1 is located outside the outer shell for easy unloading.

[0043] The grinding wheel correction unit 17 includes a mounting seat 172, which is slidably connected to the frame 12 and can slide in a direction parallel to the axes of the two grinding wheels. In actual implementation, the mounting seat 172 only needs to be free to slide back and forth toward the first grinding wheel 3, because the second grinding wheel 4 itself can be displaced for adjustment and adaptation.

[0044] A cylinder assembly 174 is fixedly mounted on the mounting seat 172 , a correction shaft 171 is mounted on the output end of the cylinder assembly 174 , and a bidirectional correction head 173 is mounted on the end of the correction shaft 171 , so as to realize correction of two grinding wheels at the same time.
