Detailed Implementation

[0032] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the first aspect of this application, a grinding device 100 is provided, including an operating table 110, a clamping frame 120, a grinding belt 130, a clamping assembly 140, and a collecting assembly 150. The clamping frame 120 is rotatably connected to the operating table 110, and the clamping frame 120 can be operably switched between being parallel to or at an angle to the operating table 110. The grinding belt 130 includes a rotatable abrasive belt 132, which extends along a first direction. The clamping assembly 140 includes a first clamping member 141 and a second clamping member 142 disposed opposite to each other. The first clamping member 141 is connected to the clamping frame 150. The frame 120 is rotatably connected; the second clamping member 142 is connected to the clamping frame 120 through the bearing member 143, and the second clamping member 142 is operable to move along the second direction or rotatably connected to the clamping frame 120; the first clamping member 141 and the second clamping member 142 form a clamping space for clamping the sample; the second direction is perpendicular to the first direction; the collection assembly 150 includes a collection cover 151, a connecting pipe 152, a collection bag 153 and a dust removal fan 154, the collection cover 151 is connected to the collection bag 153 through the connecting pipe 152, and the dust removal fan 154 is located on the connecting pipe 152.

[0034] This application involves pulling the second clamping member 142 along a second direction to place the sample in the clamping space formed by the first clamping member 141 and the second clamping member 142. Releasing the second clamping member 142 causes it to clamp and fix the sample with the first clamping member 141. Pressing the clamping frame 120 makes it parallel to the operating table 110, while simultaneously rotating the second clamping member 142, causes the sample and the first clamping member 141 to rotate, thereby grinding the sample. A collection assembly 150 is installed on the operating table 110, and iron filings are driven by the dust removal fan 154 to enter the collection bag 153 through the collection cover 151, preventing dust pollution of the environment.

[0035] In some embodiments, the operating table 110 is provided with two hinges 111 along the second direction, and the clamping frame 120 is rotatably connected to the operating table 110 via the hinges 111. This facilitates raising or lowering the clamping frame 120.

[0036] In some embodiments, the clamping frame 120 further includes a first spring 122, which is sleeved on the clamping frame 120. One end of the first spring 122 is connected to the operating table 110, and the other end is connected to the clamping frame 120. When the first spring 122 is reset, the clamping frame 120 is angled relative to the operating table 110. When the clamping frame 120 is pressed, the sample on the clamping frame 120 contacts the abrasive belt 132 for grinding. The first spring 122, positioned between the clamping frame 120 and the operating table 110, counteracts the weight of the clamping frame 120, reducing the labor intensity of lifting and pressing operations. Furthermore, when the clamping frame 120 is pressed, the first spring 122 prevents the clamping frame 120 from vibrating up and down during grinding, thus providing a cushioning effect.

[0037] In some embodiments, the first clamping member 141 includes a first clamping arm 1411 and a first clamping block 1412 connected together; the second clamping member 142 includes a second clamping arm 1421 and a second clamping block 1422 connected together; the first clamping block 1412 and the second clamping block 1422 are arranged opposite to each other to clamp the sample.

[0038] In other embodiments, the first clamping arm 1411 is rotatably connected to the clamping frame 120 via a first bearing, and the second clamping arm 1421 is connected to the clamping frame 120 via a bearing member 143. The bearing member includes a bearing disposed on the clamping frame and a bushing fixedly connected to the inner ring of the bearing. The bushing is sleeved on the second clamping arm. This facilitates the stretching of the second clamping arm 1421 in the second direction, and also allows the second clamping arm 1421 to be rotated, causing the first clamping arm 1411 to rotate together around the clamping frame 120.

[0039] In some embodiments, the first clamping arm 1411 and the second clamping arm 1421 are coaxially arranged; after the first clamping member 141 and the second clamping member 142 have clamped the sample, the second clamping arm 1421, the first clamping arm 1411 and the sample form a whole. When the second clamping arm 1421 is rotated, the first clamping arm 1411, the second clamping arm 1421 and the sample all rotate around the clamping frame 120.

[0040] In some embodiments, the clamping assembly 140 further includes a second spring 146, which is sleeved on the second clamping arm 1421 and has one end connected to the second clamping block 1422, while the other end is connected to the inner ring of the bearing. By stretching the second clamping arm 1421 along a first direction, the second clamping arm 1421 is moved along a second direction. At this time, the second spring 146 contracts, placing the sample in the clamping space formed by the first clamping block 1412 and the second clamping block 1422. When the clamping handle 144 is released, the second clamping arm 1421 returns to its original position under the action of the second spring 146, and the first clamping block 1412 and the second clamping block 1422 clamp the sample.

[0041] In some embodiments, the abrasive belt 130 further includes a drive assembly 131, which includes a drive member 1311, a drive roller 1312, and a driven roller 1313. Both the drive roller 1312 and the driven roller 1313 are rotatably connected to the operating table 110. The drive member 1311 is driveably connected to the drive roller 1312, and the abrasive belt is sleeved on the drive roller 1312 and the driven roller 1313. The drive member 1311 can be a motor, a first transmission wheel, a second transmission wheel, and a belt. The output end of the motor is connected to the first transmission wheel. The second transmission wheel and the second transmission wheel are connected via a belt drive. The second transmission wheel is coaxially connected to the drive roller 1312 and drives the motor. The motor can drive the second transmission wheel to rotate via the first transmission wheel and the belt. The second transmission wheel drives the drive roller 1312 to rotate, thereby causing the abrasive belt 132 to move along the drive roller 1312 and the driven roller 1313.

[0042] In some embodiments, the operating table 110 is further provided with a protective platform 112, which and the collecting assembly 150 are located on opposite sides of the sanding belt 132 along a first direction. The protective platform 112 can be a protective cover, which is located at the front end of the sanding belt 132 in the direction of rotation, serving a protective and isolating function to prevent personnel or clothing from being caught in the sanding belt 132. The sanding belt 132 provides protection on one side and collects iron filings generated during the sanding process on the other.

[0043] In some embodiments, the opening of the collection hood 151 is funnel-shaped, which can guide the collected materials such as iron filings into the collection hood 151 smoothly; thereby reducing the splashing or scattering of collected materials during the collection process, improving collection efficiency and maintaining environmental cleanliness.

[0044] In some embodiments, the collection bag 153 is provided with a closure 1531, which can be a button, snap, Velcro, or zipper, etc., to close the opening of the collection bag 153. At the same time, when the iron filings in the collection bag 153 reach a certain amount, the closure 1531 of the collection bag 153 is pulled open to recycle the iron filings collected in the collection bag 153, which is convenient to operate.

[0045] In some embodiments, the dust removal fan 154 is installed on the control panel 110 to ensure the stability of the dust removal fan 154.

[0046] In some embodiments, the opening of the collection hood 151 is larger in the second direction than the size of the sanding belt 132; this allows for the collection of iron filings generated during the grinding process as much as possible.

[0047] In some embodiments, the protective platform 112 is larger in size along the second direction than the sanding belt 132. This serves as a protective barrier to prevent personnel or clothing from being caught in the sanding belt 132.

[0048] In some embodiments, the transmission direction of the abrasive belt 132 on the side in contact with the sample is opposite to the rotation direction of the clamping assembly 140. This grinding method, where the abrasive belt 132 rotates in the opposite direction to the object, improves grinding efficiency, enhances grinding quality, and reduces wear on the abrasive belt 132.

[0049] In some embodiments, the clamping frame 120 is also provided with a frame handle at the end away from the hinge; this ensures operational stability and safety, and facilitates operation. The frame handle and the protective table 112 are located on the same side, serving a protective function.

[0050] In some embodiments, the second clamping member 142 is further provided with a clamping handle 144; this ensures operational stability and safety, and facilitates operation. By stretching the clamping handle 144 along the first direction, the second clamping arm 1421 can be moved along the second direction. At this time, the second spring 146 contracts, placing the sample in the clamping space enclosed by the first clamping block 1412 and the second clamping block 1422. Releasing the clamping handle 144 causes the second clamping arm 1421 to return to its original position under the action of the second spring 146. At this point, the first clamping block 1412 and the second clamping block 1422 clamp the sample.

[0051] In some embodiments, the second clamping member 142 is also provided with a crank handle 145. This ensures operational stability and safety, and facilitates operation. After the first clamping member 141 and the second clamping member 142 clamp the sample, rotating the crank handle 145 makes the edge of the sample evenly contact the abrasive belt 130. This performs a friction operation on the sample, smoothing out burrs and accumulated residue from the sample edges.

[0052] The operating principle of the grinding equipment 100 in this application is as follows:

[0053] 1. After the staff takes out the molten steel sample from the molten steel using a special sampler, they use tools to cool the sample to room temperature. Then, the staff takes the sample to the operating table 110 and begins the sample grinding operation.

[0054] 2. The operator pulls the clamping handle 144 to place the sample between the first clamping member 141 and the second clamping member 142, and then slowly releases the clamping handle 144 to clamp and fix the sample using the second spring 146.

[0055] 3. The operator starts the drive unit 1311, which drives the grinding sand belt 130 to rotate clockwise.

[0056] 4. The operator rotates the handle 145 counterclockwise to ensure uniform contact between the sample edge and the abrasive belt 130. This performs a friction operation on the sample, smoothing out any burrs and residue from the sample edges.

[0057] 5. During the grinding process, the dust removal fan 154 is activated simultaneously with the drive unit 1311. The iron filings generated by the sanding belt 132 rubbing against the sample are driven by the dust removal fan 154 and enter the collection bag 153 through the collection cover 151. This prevents dust from polluting the environment.

[0058] 6. Once the sample meets the laboratory testing standards, turn off the drive unit 1311 button, and the drive unit 1311 and the dust removal fan 154 and other equipment will stop working.

[0059] 7. After the equipment stops, the personnel pull the clamping handle 144. After the second spring 146 is released, the personnel take out the processed sample and send it to the laboratory for testing.

[0060] 8. Once the amount of iron filings in the iron filings collection bag 153 has reached a certain level, open the closure 1531 of the collection bag 153 and recycle the collected iron filings.

[0061] 9. Repeated work.
