Description

Technical Field

[0001] The utility model relates to the field of volute casting and processing, in particular to a casting volute edge milling device. Background Art

[0002] The volute is the abbreviation of the volute water diversion chamber. Because its appearance is similar to that of a snail shell, it is called the volute for short. In order to ensure uniform water supply to the water diversion mechanism, the cross-section of the volute is gradually reduced. At the same time, it can form a necessary ring in front of the water diversion mechanism to reduce the working intensity of the water diversion mechanism.

[0003] The volute is generally formed by casting. After the volute is cast, the edge of the volute needs to be milled to achieve the designed size. The milling equipment of the volute generally includes a milling bracket and a milling cutter arranged on the milling bracket. The milling cutter can move laterally on the milling bracket and can also adjust the milling angle. A rotatable rotating base is arranged below the milling cutter. The volute is fixed on the rotating base, and the position and angle of the milling cutter are adjusted so that the milling cutter contacts the edge of the volute. Then, by driving the rotating base to rotate, the purpose of milling the edge of the volute with the stationary milling cutter can be achieved. However, when the milling cutter mills the volute, a large amount of iron filings will be generated. The iron filings fall into the interior of the volute and accumulate. When a large amount of iron filings accumulate, the machine has to be stopped to clean the iron filings inside the volute, thereby reducing the processing efficiency of the volute. On the other hand, after each milling of the volute is completed, the iron filings on the rotating base also need to be cleaned, which is time-consuming and laborious. Utility Model Content

Specific embodiments

[0030] The following describes the present utility model in detail with reference to the accompanying drawings and embodiments:

[0031] The casting volute mouth edge milling equipment of the present utility model includes a milling frame 1, a milling cutter 2 is arranged on the cross beam of the milling frame 1, and a rotating base 3 is also arranged below the cross beam in cooperation with the milling cutter 2. A clamping mechanism is arranged on the upper end surface of the rotating base 3 for clamping the volute 4. During use, the clamping mechanism fixes the volute 4 on the upper end surface of the rotating base 3, and then adjusts the position of the milling cutter 2 so that the cutting edge of the milling cutter 2 contacts the mouth edge of the volute 4. Then, the rotating base 3 is driven to rotate, so that the rotating base 3 drives the volute 4 to rotate through the clamping mechanism. The rotating volute 4 cooperates with the stationary milling cutter 2 to mill the mouth edge of the volute 4. In the actual milling process, a large amount of iron chips will fall into the interior of the volute 4. When the volute 4 is processed, it is necessary to clean the upper end surface of the rotating base 3 for the next use. Sometimes, when the milling amount is large, during the milling process, the iron chips accumulated in the volute 4 will even accumulate at the mouth edge position of the volute 4, and it is necessary to stop the machine to clean the iron chips falling inside the volute 4 before continuing to process the volute 4, which affects the processing efficiency.

[0032] To this end, the present application is also specially designed with an iron filings discharging device. The iron filings discharging device includes a discharging hole 5 coaxially opened on the rotating base 3 and a collecting device connected to the upper end of the discharging hole 5. When the present device is in use, when the milling cutter 2 mills the edge of the volute 4, the generated iron filings fall into the interior of the volute 4 and also into the collecting device. The iron filings falling into the collecting device are discharged downward from the discharging hole 5, achieving the purpose of discharging iron filings while milling the volute 4, and effectively improving the processing efficiency.

[0033] In this embodiment, the collecting device includes a plurality of converging plates 6. A hinge rod 7 is fixedly provided on the lower end surface of each converging plate 6. The plurality of hinge rods 7 are connected end to end to form a closed polygon. A connecting body 8 is provided at each corner of the polygon. Both ends of each hinge rod 7 are hinged to the corresponding connecting body 8. A flexible screen cloth 9 is provided between every two adjacent converging plates 6. The internal space of the polygon formed by the plurality of hinge rods 7 is connected to the upper end of the discharging hole 5. When in use, first rotate the plurality of converging plates 6 towards the middle so that each converging plate 6 converges together to reduce the expanded volume of the collecting device. Then place the volute 4 on the upper end surface of the rotating base 3 and make each converging plate 6 enter the interior of the volute 4. Then rotate each converging plate 6 outwards so that the converging plates 6 expand inside the volute 4 and jointly form a bucket-shaped container with the flexible screen cloth 9. Then clamp and fix the volute 4 through the clamping mechanism. Then adjust the position of the milling cutter 2 so that the cutting edge of the milling cutter 2 contacts the edge of the volute 4. Then drive the rotating base 3 to rotate, and the purpose of milling the edge of the rotating volute 4 with the stationary milling cutter 2 can be achieved. At this time, the generated iron filings fall into the interior of the volute 4 and also into the bucket-shaped container jointly formed by the converging plates 6 and the flexible screen cloth 9, and enter the discharging hole 5 of the rotating base 3 through the interior of the polygon formed by the plurality of hinge rods 7. Then the iron filings are discharged from the lower end of the discharging hole 5, achieving the purpose of discharging iron filings while milling the volute 4, and effectively improving the processing efficiency.

[0034] In order to achieve the purpose of facilitating the driving of the collecting device to contract inward to reduce the volume and expand outward to form a hopper-shaped container, in this embodiment, side plates 10 are fixedly arranged on the outer surface of each hinge rod 7 along the axis of the rotating base 3. Both sides of each side plate 10 are fixedly arranged with the corresponding side plates 10. Each side plate 10 extends into the inner part of the outlet hole 5 of the rotating base 3. At the position corresponding to the side plate 10 on the inner side wall of the outlet hole 5 of the rotating base 3, guide blocks 11 equal in number to the side plates 10 are fixedly arranged. The inner side surface of each guide block 11 is in sliding contact with the outer side surface of the corresponding side plate 10. The upper end surface of each guide block 11 is fixedly provided with a limiting block 12, and an inwardly inclined slope is formed on the upper end surface of each limiting block 12; on the upper end surface of each converging plate 6, fixing blocks 13 are symmetrically and fixedly arranged. A spring 14 is arranged between every two adjacent converging plates 6, and both ends of the spring 14 are fixedly arranged with the corresponding fixing blocks 13; when it is necessary to contract the converging plates 6 to reduce the volume, by driving the side plates 10 to move downward between several guide blocks 11, the side plates 10 drive the converging plates 6 and the flexible screen cloth 9 to move downward through the hinge rods 7. When the converging plates 6 move downward, they are restricted by the slopes of the limiting blocks 12, so that each converging plate 6 rotates inward. At the same time, the spring 14 is compressed by the fixing blocks 13, so that each converging plate 6 and the flexible screen cloth 9 are folded together. At this time, the spring 14 is compressed and bent inward, and then it is convenient to place the volute 4, so that the converging plates 6 and the flexible screen cloth 9 folded together enter the inside of the volute 4, and then the volute 4 is fixed by the clamping mechanism; then the side plates 10 are driven to move upward, so that the side plates 10 drive each converging plate 6 and the flexible screen cloth 9 to move upward through the hinge rods 7. Then the spring 14 elongates to push each converging plate 6 to rotate outward, so that each converging plate 6 and the flexible screen cloth 9 expand outward until the outer side surface of the converging plate 6 contacts the slope of the limiting block 12, so that the converging plates 6 and the flexible screen cloth 9 form a hopper-shaped container, which is convenient for collecting the iron filings generated when the milling cutter 2 mills the edge of the volute 4.

[0035] In order to achieve the purpose of driving the side plates 10 to move up and down, in this embodiment, a threaded column 15 is slidably connected in the outlet hole 5 of the rotating base 3 in the up and down direction. A chip discharging hole 16 adapted to the side plates 10 is formed in the threaded column 15 along the axis. The lower end surface of each side plate 10 is inserted into the chip discharging hole 16 of the threaded column 15 and fixedly arranged with the threaded column 15; during use, by driving the threaded column 15 to move up and down, the purpose of driving the side plates 10 to move up and down by the threaded column 15 is achieved. When the volute 4 is processed, the generated iron filings are collected by the convergence of the converging plates 6 and the flexible screen cloth 9, and then fall into the internal channels formed by several side plates 10. Then the iron filings continue to fall into the chip discharging hole 16 of the threaded column 15, and then the iron filings are discharged from the lower end of the chip discharging hole 16, achieving the purpose of discharging iron filings while milling the volute 4, and effectively improving the processing efficiency.

[0036] In order to achieve the purpose of driving the threaded column 15 to move up and down, in this embodiment, a rotating sleeve 17 is coaxially arranged on the lower end surface of the rotating base 3, and the rotating sleeve 17 is rotatably connected to the rotating base 3. A nut 18 is coaxially arranged on the lower end surface of the rotating sleeve 17, and the nut 18 is threadedly connected to the threaded column 15. By rotating the nut 18, the nut 18 rotates on the rotating base 3 through the rotating sleeve 17, and at the same time drives the threaded column 15 to slide up and down in the lead-out hole 5 of the rotating base 3, so that the threaded column 15 drives the side plate 10 and the gathering plate 6 to move up and down synchronously.

[0037] In this embodiment, the clamping mechanism includes a bottom plate 19 fixedly arranged on the upper end surface of the rotating base 3. A through hole 20 communicating with the lead-out hole 5 of the rotating base 3 is coaxially opened on the upper end surface of the bottom plate 19. The outer side surface of each guide block 11 is fixedly arranged on the inner side wall of the through hole 20 of the bottom plate 19. A plurality of clamping blocks 21 are slidably arranged on the upper end surface of the bottom plate 19 along the radial direction of the bottom plate 19. Each clamping block 21 is also provided with a locking mechanism for realizing the switching between the two states of fixing the position of the clamping block 21 and the bottom plate 19 and relative sliding. When the locking mechanism is opened, the clamping block 21 and the bottom plate 19 are fixed in position to form a whole. When the locking mechanism is closed, the clamping block 21 and the bottom plate 19 are released from the fixed position to realize relative sliding. When it is necessary to clamp the volute 4, first place the volute 4 in the middle of the bottom plate 19, then close the locking mechanism, slide each clamping block 21 inward until the clamping block 21 clamps the volute 4, and then open the locking mechanism to fix the position of the clamping block 21 and the bottom plate 19, so as to achieve the purpose of clamping the volute 4.

[0038] In order to increase the smoothness of the sliding of the clamping block 21 on the bottom plate 19, in this embodiment, a sliding groove 22 is radially opened on the upper end surface of the bottom plate 19 corresponding to the clamping block 21. A sliding rail adapted to the sliding groove 22 is fixedly arranged on the lower end surface of the clamping block 21. The clamping block 21 is slidably connected to the bottom plate 19 through the sliding rail and the sliding groove 22. Move the clamping block 21 to slide on the bottom plate 19, and at the same time the sliding rail slides in the sliding groove 22, increasing the smoothness of the movement of the clamping block 21.

[0039] In this embodiment, the locking mechanism includes a bolt 23 penetrating through the clamping block 21, and the bolt 23 is threadedly connected to the clamping block 21. Rotate the bolt 23 to move downward so that the bottom end of the bolt 23 abuts against the inner bottom wall of the sliding groove 22 to realize the opening of the locking mechanism. Rotate the bolt 23 to move upward so that the bottom end of the bolt 23 is separated from the inner bottom wall of the sliding groove 22 to realize the closing of the locking mechanism.

[0040] In order to achieve the purpose of driving the rotating base 3 to rotate, in this embodiment, the lower end of the rotating base 3 is rotatably connected to a support plate 24, and a plurality of support legs are fixedly provided on the lower end surface of the support plate 24, so that the support plate 24 is placed on the ground through the support legs to maintain a set height, and a gear ring 25 is fixedly provided on the outer surface of the rotating base 3; a motor 26 is fixedly provided on the outer surface of the support plate 24, and a gear 27 is coaxially fixedly provided on the output shaft of the motor 26, and the gear 27 is meshed with the gear ring 25; the motor 26 rotates to drive the gear 27, so that the gear 27 drives the rotating base 3 to rotate in the left plate through the gear ring 25, thereby achieving the purpose of driving the rotating base 3.

[0041] The working principle of the utility model is that when the volute 4 needs to be processed, the nut 18 is first rotated so that the nut 18 drives the threaded column 15 to move downward, and the threaded column 15 drives the gathering plate 6 and the flexible screen cloth 9 to move downward through the side plate 10, and the gathering plate 6 moves downward to cooperate with the inclined surface of the limiting block 12, so that each gathering plate 6 rotates inward, so that the gathering plate 6 and the flexible screen cloth 9 are gathered together, and then the volute 4 is placed between a plurality of clamping blocks 21, and each gathering plate 6 enters the interior of the volute 4, and then the nut 18 is rotated again to drive the threaded column 15 to move upward, so that the threaded column 15 drives the gathering plate 6 and the flexible screen cloth 9 to move upward through the side plate 10, and each gathering plate 6 rotates outward under the thrust of the spring 14, so that the outer side surface of the gathering plate 6 is in contact with the inclined surface of the limiting block 12, and the flexible screen cloth 9 is unfolded; then the clamping block 21 is moved to clamp the volute 4, and then the nut 18 is rotated. The movable bolt 23 moves downward, so that the bottom end of the bolt 23 contacts the inner bottom wall of the slide groove 22, so as to fix the position of the clamping block 21 and the bottom plate 19, and achieve the purpose of clamping the volute 4. Then, the position of the milling cutter 2 is adjusted, so that the cutting edge of the milling cutter 2 contacts the edge of the volute 4, and then the motor 26 is started to drive the gear 27 to rotate. The gear 27 drives the rotating base 3 to rotate through the gear ring 25. The rotating base 3 drives the volute 4 to rotate through the clamping block 21, so that the stationary milling cutter 2 mills the rotating volute 4. The iron chips generated by the milling fall into the interior of the volute 4 and enter the bucket-shaped container composed of the gathering plate 6 and the flexible screen cloth 9 at the same time. Then, the iron chips continue to move downward into the space surrounded by the side plate 10, and then the iron chips enter the chip discharge hole 16 of the threaded column 15 and are discharged from the bottom end of the chip discharge hole 16, achieving the purpose of milling the volute 4 while discharging the iron chips, and effectively improving the processing efficiency.
