[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-6 The embodiment of the present invention provides a surface grinder for metal processing, comprising a base plate 1 and a grinding frame 2 fixedly connected to the base plate 1, a processing table 3 fixedly connected to the top of the base plate 1, a workpiece body 7 is arranged inside the processing table 3, and a support member is provided at the bottom of the inner cavity of the processing table 3, which is used to support the workpiece body 7 to limit the downward movement of the workpiece body 7;

[0027] A turning piece is provided on the side of the processing table body 3 away from the grinding frame 2, and the turning piece is used to turn the workpiece body 7;

[0028] A limit member is provided on one side of the processing table body 3 close to the grinding frame 2 , and the limit member is used to limit the movement of the workpiece body 7 so that the grinder can grind the workpiece body 7 .

[0029] In the above technical solution, the flipping of the workpiece body 7 by the flipping part avoids the trouble of manually disassembling the workpiece body 7 after processing one side of the workpiece body 7, protects the safety of the operator, and at the same time shortens the time for processing the same workpiece, thereby improving production efficiency. The restriction and support of the workpiece body 7 by the limiter and the support part ensure that the workpiece body 7 is restricted and remains stationary during grinding, and at the same time avoids the change of the position of the workpiece body 7 after flipping, which in turn causes deviation in grinding and affects the subsequent processing accuracy.

[0030] Specifically, the support member includes four limit blocks 401, which are symmetrically arranged on both sides of the inner cavity of the processing table body 3. Two trapezoidal slides 402 are slidingly arranged on the inner side of the limit blocks 401. The two trapezoidal slides 402 are fixedly connected to a side close to the limit blocks 401 with multiple sliding springs 403. The other ends of the multiple sliding springs 403 are fixedly connected to both sides of the inner cavity of the processing table body 3. Two bevel slides 404 are slidingly connected to the side of the processing table body 3 away from the grinding frame 2, and the two bevel slides 404 are in one-to-one contact with the trapezoidal slides 402.

[0031] In the above technical solution, the angled slide 404 acts on the trapezoidal slide 402 , thereby enabling the trapezoidal slide 402 to restrict or relax the downward movement of the workpiece body 7 .

[0032] Specifically, the top of the sliding spring 403 is set as a plane, and the plane on the top of the sliding spring 403 is slidingly provided with a support plate 405. The workpiece body 7 is set on the top of the support plate 405. The bottom of the angled slide 404 is fixedly connected with a lifting spring 406, and the other end of the lifting spring 406 is fixedly connected to the bottom of the inner cavity of the processing table body 3.

[0033] In the above technical solution, the sliding relationship between the angled slide plate 404 and the trapezoidal slide plate 402 prevents the workpiece body 7 from moving downward during the grinding process.

[0034] Specifically, the flip part includes a sliding groove plate 501, which is fixedly connected to the side of the processing table 3 away from the grinding frame 2. The top of the sliding groove plate 501 is slidably connected to the sliding tooth plate 502. The middle of the sliding tooth plate 502 is slidably connected to the rotating connecting column 503. The rotating connecting column 503 is slidably connected to the side of the processing table 3 away from the grinding frame 2. The end of the rotating connecting column 503 away from the processing table 3 is fixedly connected to the pushing slide 504. The pushing slide 504 is slidably set on the bottom plate 1, and the angled slide 404 contacts the side of the pushing slide 504.

[0035] In the above technical solution, by rotating the connection relationship of the connecting column 503, the sliding of the pushing slide 504 can drive the sliding of the sliding tooth plate 502. At the same time, through the interference relationship between the angled slide 404 and the pushing slide 504, the support part and the flip part are started.

[0036] Specifically, the flip part also includes a connecting column 506, which is rotatably connected to the side of the processing table 3 away from the grinding frame 2. The end of the connecting column 506 away from the processing table 3 is fixedly connected to a rotating gear 507, and the rotating gear 507 is engaged with the sliding tooth plate 502. The end of the connecting column 506 located inside the processing table 3 is fixedly connected to a fixed swivel 508, and the fixed swivel 508 is in contact with one side of the workpiece body 7.

[0037] In the above technical solution, by engaging the rotating gear 507 with the sliding tooth plate 502 , the sliding of the sliding tooth plate 502 can drive the rotation of the rotating gear 507 , and then the workpiece body 7 is turned over through the fixed rotating body 508 .

[0038] Specifically, a plurality of corner clamping grooves 51 are opened on one side of the inner cavity of the processing table body 3 close to the pushing slide plate 504. The corner clamping grooves 51 are arranged in a straight line inside the processing table body 3. A corner clamping block 505 is fixed on the side of the sliding groove plate 501, and the corner clamping block 505 is clamped with the corner clamping groove 51.

[0039] In the above technical solution, the locking state between the corner groove 51 and the corner block 505 prevents the sliding tooth plate 502 from moving independently, thereby avoiding the workpiece body 7 from turning over independently.

[0040] Specifically, the limiting component includes a rotating spring column 601, which is rotatably connected to the side of the processing table 3 away from the pushing slide 504. The side of the rotating spring column 601 is fixedly connected to a connecting spring plate 602. The side of the connecting spring plate 602 away from the workpiece body 7 is fixedly connected to a limiting spring 603. The other end of the limiting spring 603 is fixedly connected to the inner cavity of the processing table body 3. The side of the connecting spring plate 602 close to the workpiece body 7 is fixedly connected to a rotating connecting block 604. The end of the rotating spring column 601 close to the workpiece body 7 is fixedly connected to the limiting swivel 605. The rotating connecting block 604 is slidably connected to the side of the limiting swivel 605 away from the workpiece body 7.

[0041] In the above technical solution, the limit spring 603 elastically stretches the limit rotator 605, so that the workpiece body 7 that contacts the limit rotator 605 is restricted and cannot move, thereby facilitating the grinding work.

[0042] Specifically, the working principle and operation method of the utility model are as follows:

[0043] When not in use, the corner block 505 is engaged with the corner groove 51 , and the support plate 405 is arranged on the plane at the top of the trapezoidal slide 402 .

[0044] During use, the operator places the workpiece body 7 into the processing table body 3, and the workpiece body 7 pushes the limiting rotatable body 605 to move in the direction away from the fixed rotatable body 508, thereby driving the rotating spring column 601 to move in the direction away from the fixed rotatable body 508. At the same time, the limiting rotatable body 605 drives the rotating connecting block 604 to move in the direction away from the fixed rotatable body 508, thereby driving the connecting spring plate 602 to move in the direction away from the fixed rotatable body 508, and compressing the limiting spring 603. Under the elastic extension action of the limiting spring 603, the workpiece body 7 is restricted from moving, and then the grinding work is carried out.

[0045] After one side is ground, the operator pushes the slide 504 toward the direction close to the processing table body 3. The slide 504 drives the rotating connecting column 503 to move toward the direction close to the processing table body 3. The sliding groove plate 501 drives the corner block 505 to slide in the direction away from the pushing slide 504, so that the corner block 505 is no longer engaged with the corner groove 51. At the same time, the slide 504 is pushed to contact one end of the bevel slide 404, and then the bevel slide 404 is pushed to move in the direction away from the pushing slide 504. Under the restriction of the trapezoidal slide 402 by the limit block 401, the bevel slide 404 pushes the trapezoidal slide 402 to slide toward the direction close to the processing table body 3, and then the support plate 405 is pressed against the inclined surface of the trapezoidal slide 402, so that the support plate 405 can move downward.

[0046] At this time, the sliding pushes the slide plate 504, which in turn drives the rotating connecting column 503 to slide, and the rotating connecting column 503 drives the sliding tooth plate 502 to slide on the top of the sliding groove plate 501. Since the sliding tooth plate 502 and the rotating gear 507 are in a clamping state, as the sliding tooth plate 502 slides, the rotating gear 507 rotates, and the rotating gear 507 drives the connecting rotating column 506 to rotate, and then drives the fixed rotating body 508 to rotate, and the fixed rotating body 508 drives the workpiece body 7 to flip over and make the support plate 405 move downward, thereby compressing the lifting spring 406, and the workpiece body 7 drives the limiting rotating body 605 to rotate, and then drives the rotating elastic column 601 to rotate, and the rotating connecting block 604 slides on one side of the limiting rotating body 605.

[0047] After the workpiece body 7 is flipped over, the push slide 504 is released. Under the elastic extension of the lifting spring 406, the support plate 405 pushes the workpiece body 7 to move upward. At this time, the trapezoidal slide 402 moves away from the processing table body 3 under the elastic extension of the sliding spring 403, so that the support plate 405 conflicts with the plane at the top of the trapezoidal slide 402, and the support plate 405 cannot move downward, thereby preventing the workpiece body 7 from moving downward, and then the grinding work on the other side can be carried out.

[0048] At this time, the trapezoidal slide 402 pushes the angled slide 404 to move away from the trapezoidal slide 402, and then pushes the pushing slide 504 to move away from the processing table 3. The pushing slide 504 drives the rotating connecting column 503 to move away from the fixed swivel 508, and then drives the corner block 505 to move away from the fixed swivel 508, so that the corner block 505 is engaged with the corner groove 51, thereby preventing the sliding tooth plate 502 from sliding.

[0049] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
