[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0033] The present invention provides as Figures 1 - 10A mechanical part grinding device shown in the figure includes a first housing 1. On one side above the first housing 1, there is a second housing 2. Inside the second housing 2, a loading cylinder 3 is rotatably installed. At the bottom end of the second housing 2, a connecting block 4 is fixedly installed. In the middle of the connecting block 4, a first chute 400 is opened. Inside the first chute 400, a moving block 5 is slidably clamped. Inside the loading cylinder 3, two symmetrically arranged inclined plates 301 are rotatably installed. The moving block 5 is located between the two inclined plates 301. On both sides of the connecting block 4, chutes communicating with the first chute 400 are opened. On both sides of the moving block 5, fixing blocks 502 are fixedly installed. The fixing blocks 502 are slidably clamped inside the corresponding chutes. On the outer side of one side of the connecting block 4, a first motor 402 is fixedly installed. The driving end of the first motor 402 is fixedly installed with a first circular plate 403. On one side of the first circular plate 403, a crank rod 404 is rotatably installed. The end of the crank rod 404 far from the first circular plate 403 is rotatably installed on the fixing block 502. On the corresponding two sides of the moving block 5 and the fixing block 502, second chutes 501 are opened. Inside the second chutes 501, sliding rods 503 are slidably clamped. Between the sliding rods 503 and the second chutes 501, first springs 504 are fixedly installed. At the lower end inside the loading cylinder 3, a plurality of uniformly distributed first bumps 302 are fixedly installed. The sliding rods 503 are used in cooperation with the first bumps 302. On the lower surface of the connecting block 4, a hopper 401 is fixedly installed. In the middle of the moving block 5, a leakage slot 500 is opened.
[0034] During actual use, the worker directly pours the cylindrical parts to be polished into the interior of the loading cylinder body 3. At this time, the cylindrical parts are randomly stacked inside the loading cylinder body 3. At this time, the first motor 402 operates. The operation of the first motor 402 drives the first circular plate 403 to rotate. One end of the crank lever 404 is rotatably installed on the fixed block 502. Therefore, the crank lever 404 will drive the fixed block 502 to reciprocate inside the chute, and then the fixed block 502 will drive the moving block 5 to move up and down. When the moving block 5 moves up and down, it will exert a pushing force on the parts inside the loading cylinder body 3, thereby causing some parts to enter the inside of the material leakage groove 500. The inclined plate 301 enables the parts to more easily enter the inside of the material leakage groove 500. And the parts that enter the inside of the material leakage groove 500 will be arranged neatly horizontally under continuous back-and-forth movement. However, at this time, some horizontal parts are likely to appear inside the loading cylinder body 3, which may cause the material leakage groove 500 to be blocked and the parts cannot enter. Therefore, the first convex block 302 is provided. When the moving block 5 rises, at this time, the sliding rod 503 is driven to contact one of the first convex blocks 302. At this time, the sliding rod 503 is located at the outermost edge position of the second chute 501. Therefore, when the moving block 5 rises, it can exert a pushing force on the first convex block 302. The first convex block 302 is pushed, which causes the loading cylinder body 3 to rotate. When the moving block 5 descends, at this time, the sliding rod 503 is pushed by the first convex block 302. At this time, the sliding rod 503 compresses the first spring 504. Therefore, when the moving block 5 descends, it will not drive the loading cylinder body 3 to rotate, which facilitates the continuous one-way rotation of the loading cylinder body 3. The rotation of the loading cylinder body 3 can drive the parts inside it to rotate. Every time the moving block 5 makes a back-and-forth movement, the loading cylinder body 3 will rotate by an angle. Under the continuous rotation of the loading cylinder body 3, the parts inside it will gradually tend to be neatly arranged, which is convenient for the parts to enter the inside of the material leakage groove 500. The parts that enter the material leakage groove 500 will fall into the interior of the material leakage hopper 401. The material leakage hopper 401 can stably convey the parts to the next working position.
[0035] A plurality of uniformly distributed brackets 6 are fixedly installed on the lower surface of the connecting block 4. Two symmetrically arranged inclined rods 601 are installed on the brackets 6. One end of the inclined rod 601 is fixedly installed with a horizontal rod 602. The inclined rod 601 is used to carry the parts to be polished. The feeding component 7 is used to convey the parts on the horizontal rod 602 to the polishing component 8. The polishing component 8 is used to polish the parts. The power component 9 is used to provide the kinetic energy required for polishing.
[0036] When the parts are neatly arranged and enter the hopper 401, the hopper 401 will neatly send the parts between the two inclined rods 601. When the parts fall on the inclined rods 601, because the inclined rods 601 are inclined, the parts will slide to the position of the horizontal rod 602 driven by gravity. The feeding component 7 works to convey one of the parts to the grinding component 8. After the grinding component 8 finishes grinding, the feeding component 7 conveys again. Driven by gravity, the parts continuously slide into the position of the horizontal rod 602. The parts at the position of the horizontal rod 602 will be pushed by the parts on the inclined rods 601 into the feeding component 7 and then conveyed by the feeding component 7.
[0037] On the side of the horizontal rod 602 far from the inclined rod 601, there is a feeding component 7. The feeding component 7 includes a cross-shaped cylinder 701. The cross-shaped cylinder 701 is rotatably installed on the inner wall of the first housing 1. One side of the cross-shaped cylinder 701 is fixedly installed with a second circular plate 703. Four uniformly distributed tip bumps 704 are integrally formed on the second circular plate 703. Feed cylinders 702 are fixedly installed at the four top positions of the cross-shaped cylinder 701. A retaining rod 705 is fixedly installed between adjacent two feed cylinders 702. A second motor 706 is fixedly installed inside the first housing 1. The driving end of the second motor 706 is fixedly installed in the middle of the cross-shaped cylinder 701.
[0038] The second motor 706 is a stepper motor. The second motor 706 rotates 90° each time. The parts on the horizontal rod 602 will be pushed by the parts on the inclined rods 601 into the interior of the feed cylinder 702. Then the second motor 706 drives the cross-shaped cylinder 701 to rotate. At this time, the feed cylinder 702 drives the parts to rotate to the position above the cross-shaped cylinder 701. At this time, driven by gravity, the parts will slide along the cross-shaped cylinder 701 into the grinding component 8. During the rotation of the cross-shaped cylinder 701, in order to prevent the parts from falling, the retaining rod 705 is set to block the parts, thereby realizing continuous conveying of the parts.
[0039] Below the feeding component 7 is provided with a grinding component 8. On one side of the grinding component 8 is provided a power assembly 9. The grinding component 8 includes a grinding cylinder body 801 which is fixedly installed inside the first housing 1. On one side of the grinding cylinder body 801 are opened a plurality of uniformly distributed grooves 802. On one side of the grinding cylinder body 801 are fixedly installed two symmetrically arranged mounting blocks 804. Below the grinding cylinder body 801 is provided a baffle plate 803. One side of the baffle plate 803 is rotatably installed on the lower surface of the lower mounting block 804. On one side of the baffle plate 803 is opened a mating groove 809. In the middle of the mounting block 804 is rotatably clamped a linkage rod 805. At the lower end of the linkage rod 805 is opened a spiral groove 807 which meshes with the mating groove 809. On the linkage rod 805 is fixedly installed a mounting plate 806. Between the mounting plate 806 and the lower mounting block 804 is fixedly installed a second spring 808. On the side of the grinding cylinder body 801 away from the groove 802 is detachably installed a grinding stone 810. On the lower surface of the first housing 1 is fixedly installed a discharge port 101.
[0040] When the cross cylinder body 701 rotates, it will drive the second circular plate 703 and the tip convex block 704 to rotate. When the tip convex block 704 rotates, it will generate a push on the linkage rod 805. When the linkage rod 805 is pushed, the spiral groove 807 will slide inside the mating groove 809, and then the mating groove 809 will rotate around the mounting block 804. At this time, the grinding cylinder body 801 is in an open state. When the cross cylinder body 701 rotates 90°, the linkage rod 805 will rise under the action of the second spring 808 to drive the baffle plate 803 to return to its original position. At this time, the grinding cylinder body 801 is in a closed state, so that the discharge of the parts inside the grinding cylinder body 801 and the feeding of the next part can be accurately controlled according to the rotation of the cross cylinder body 701.
[0041] The power assembly 9 includes a third motor 901 which is fixedly installed inside the first housing 1. At the driving end of the third motor 901 is fixedly installed a first bevel gear 902. Meshed with one side of the first bevel gear 902 is a second bevel gear 903. On the upper surface of the second bevel gear 903 is fixedly installed a mounting rod 904. On the mounting rod 904 are fixedly installed a plurality of rubber plates 905 corresponding to the grooves 802. On the rubber plates 905 are integrally formed a plurality of uniformly distributed rubber convex blocks 906. The mounting rod 904 is rotatably installed on the inner wall of the first housing 1 through a mounting bracket.
[0042] When the device is working, the third motor 901 works to drive the first bevel gear 902 and the second bevel gear 903 to rotate. The rotation of the second bevel gear 903 drives the mounting rod 904 and the rubber plate 905 to rotate. When the rubber plate 905 rotates, the rubber bump 906 contacts the surface of the parts inside the grinding cylinder 801. Since the material of the rubber bump 906 is rubber, the rubber bump 906 will deform when contacting the parts, pushing the parts to fit against the surface of the grindstone 810. And because the rubber plate 905 and the rubber bump 906 are in a rotating state, the cylindrical parts will also be driven to rotate, thereby realizing the grinding of the side surface of the cylindrical parts. The ground parts will fall through the discharge port 101, and only a storage device needs to be placed below the discharge port 101.
[0043] Working principle: In actual use, the worker first pours the cylindrical parts into the interior of the loading cylinder 3. The first motor 402 works to drive the moving block 5 to move up and down reciprocally, enabling the parts inside the loading cylinder 3 to enter the leakage trough 500 and be neatly arranged. Moreover, when the moving block 5 moves reciprocally, it can also drive the loading cylinder 3 to rotate so that the parts inside it tend to be neatly arranged.
[0044] The hopper 401 conveys the parts neatly to the inclined rod 601. Driven by gravity, the parts will enter the position of the horizontal rod 602. Under the pushing action of the parts on the inclined rod 601, the parts at the position of the horizontal rod 602 will enter the interior of the cross cylinder 701. The second motor 706 rotates to convey the parts into the interior of the grinding cylinder 801. The third motor 901 works to drive the rubber plate 905 and the rubber bump 906. The rubber bump 906 squeezes the parts against the surface of the grindstone 810 and drives the parts to rotate, thereby realizing the grinding of the parts.
[0045] When the cross cylinder 701 rotates, it drives the second circular plate 703 and the tip bump 704 to rotate. The rotation of the tip bump 704 drives the linkage rod 805 to move up and down reciprocally. When the linkage rod 805 moves up and down reciprocally, it drives the baffle 803 to rotate, thereby controlling the opening and closing of the grinding cylinder 801, and the discharge of the parts can be precisely matched with the feeding of the parts.
[0046] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
