Description

TECHNICAL FIELD

[0001] The utility model relates to the field of finishing mechanism, especially relates to metal casting production finishing mechanism. BACKGROUND

[0002] The technical background of metal casting production finishing mechanism mainly comes from the continuous development of casting process and the increasing requirement for casting quality. In the casting process, due to the cooling and solidification of metal liquid and the characteristics of casting material, various defects often appear on the surface and inside of the casting, so a special finishing mechanism is invented.

[0003] In the prior art, when the metal casting is finished, the workpiece is clamped by the clamping plate, and then the workpiece surface is polished by rotating the polishing wheel. However, the existing clamping method of clamping the workpiece by the clamping plate has a certain degree of deviation in the position of the clamped workpiece each time. When the workpiece is not clamped in the center and the finishing work is directly carried out, it will directly cause the deviation of the position judgment of the workpiece during the processing of the finishing mechanism. This deviation may cause the polishing wheel to not accurately align the part of the workpiece that needs to be finished, thereby causing the size, shape or surface quality of the finished workpiece to not meet the design requirements, and the workpiece needs to be finished twice to meet the standard. This will seriously affect the finishing work, especially when the casting with high precision is finished. This problem is particularly prominent, so a metal casting production finishing mechanism needs to be improved to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] In order to overcome the problem that the position of the clamped workpiece has deviation and cannot ensure that the workpiece is centered, and when the deviation is large, the finishing of some areas will not meet the standard and needs to be polished and finished again.

[0005] The technical scheme of the utility model is: a metal casting production finishing mechanism, which comprises a workbench, a placing table and a polishing mechanism, the bottom of the workbench is fixedly connected with a support frame, the inside of the workbench is provided with a polishing mechanism, the inner side of the workbench is fixedly connected with a placing table, the inside of the workbench is rotatably connected with a rotating disc, the inside of the rotating disc is fixedly connected with a first fixed rod, the outside of the placing table is slidably connected with a sliding block, the inside of the sliding block is fixedly connected with a second fixed rod, a connecting rod is rotatably connected between the second fixed rod and the first fixed rod, the inner side of the sliding block is fixedly connected with a clamping block, and the sliding block and the clamping block are slid inward to clamp the workpiece by rotating the rotating disc.

[0006] Preferably, the placing table is provided with a sliding groove at the relative position of the sliding block, and the sliding block is slidably connected in the sliding groove.

[0007] Preferably, the workbench is provided with a matching rotating groove at the relative position of the rotating disc, and the rotating disc is rotatably connected in the rotating groove.

[0008] Preferably, the working platform is internally rotatably connected to a worm gear, the front of the worm gear is fixedly connected to a worm wheel, the worm gear is externally engaged with a first knob, the first knob is fixedly connected to the outside of the rotating disk, the working platform is internally fixedly connected to a first fixed shell, the first fixed shell is internally provided with a first fan, the first fixed shell is internally fixedly connected to a filter plate body, the first fixed shell is internally fixedly connected to an exhaust grille, and the support frame is internally slidably connected to a collection hopper.

[0009] Preferably, the working platform has a through slot inside, and the position of the through slot corresponds to the position of the collection hopper.

[0010] Preferably, the grinding mechanism includes a first motor, which is fixedly connected to the right side of the work platform. The output end of the first motor is fixedly connected to a first threaded rod, which is rotatably connected to the inside of the work platform. The external thread of the first threaded rod is connected to a sliding seat, which is slidably connected to the inside of the work platform. The top of the sliding seat is fixedly connected to a second motor, which is fixedly connected to a second threaded rod, which is rotatably connected to the inside of the sliding seat. The external thread of the second threaded rod is connected to a sliding bracket, which is slidably connected to the inside of the sliding seat. The inside of the sliding bracket is provided with a grinding wheel body.

[0011] Preferably, the sliding seat has a groove at the relative position of the sliding bracket, and the sliding bracket is slidably connected inside the groove.

[0012] The beneficial effects of this utility model are as follows: Compared with the inability to guarantee the centering of the workpiece during clamping, by adding a rotating disk, a first fixed rod, a second fixed rod and a connecting rod, the rotation of the rotating disk causes the sliding block to slide synchronously, driving the clamping block to move and clamp the workpiece, thus centering the workpiece and improving the clamping accuracy. This avoids the problem that the workpiece cannot be centered due to deviation in the clamping position. When the deviation is large, it will cause some areas to be under-finished and require secondary grinding and finishing. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a metal casting production and finishing mechanism, including a work platform 1, a placement table 21, and a grinding mechanism. A support frame 4 is fixedly connected to the bottom of the work platform 1. A grinding mechanism is installed inside the work platform 1. The placement table 21 is fixedly connected to the inner side of the work platform 1. A rotating disk 22 is rotatably connected inside the work platform 1. A first fixing rod 23 is fixedly connected inside the rotating disk 22. A sliding block 24 is slidably connected to the outside of the placement table 21. A second fixing rod 25 is fixedly connected inside the sliding block 24. A connecting rod 26 rotatably connects the second fixing rod 25 and the first fixing rod 23. A clamping block 27 is fixedly connected to the inner side of the sliding block 24. The rotation of the rotating disk 22 drives the sliding block 24 and the clamping block 27 to slide inward to clamp the workpiece. In use, the workpiece is placed on the placement table 24. At the placement platform 21, the rotating disk 22 rotates, and through the cooperation of the first fixed rod 23, the connecting rod 26 and the second fixed rod 25, the sliding blocks 24 around the platform slide inward synchronously, causing the clamping block 27 to contact the workpiece and clamp the workpiece, thus ensuring that the workpiece is centered and then ground by the grinding mechanism. The placement platform 21 has a groove at the relative position of the sliding block 24, and the sliding block 24 is slidably connected inside the groove. The groove guides the sliding block 24 to slide linearly outside the work platform 1, causing the clamping block 27 to clamp the workpiece. The work platform 1 has a matching rotating groove at the relative position of the rotating disk 22, and the rotating disk 22 is rotatably connected inside the rotating groove. The rotating groove restricts the position of the rotating disk 22 and prevents the displacement of the rotating disk 22 from affecting the sliding of the sliding block 24.

[0022] Please see Figure 1 - Figure 5 In this embodiment, a worm gear 28 is rotatably connected inside the working platform 1, a worm wheel 29 is fixedly connected to the front of the worm gear 28, and a first knob 210 is engaged with the outside of the worm gear 28. The first knob 210 is fixedly connected to the outside of the rotating disk 22. A first fixed shell 211 is fixedly connected inside the working platform 1. A first fan 212 is installed inside the first fixed shell 211. A filter plate body 213 is fixedly connected inside the first fixed shell 211. An exhaust grille 214 is fixedly connected inside the first fixed shell 211. A collection hopper 215 is slidably connected inside the support frame 4. The first fan 212 blows air to drive the debris generated during the finishing process to stay on the surface of the workpiece, causing scratches or other damage. A through groove is opened inside the working platform 1, and the position of the through groove corresponds to the position of the collection hopper 215. The debris blown by the first fan 212 falls into the collection hopper 215 through the through groove and is stored centrally, which is convenient for workers to store it centrally later.

[0023] Please see Figure 2 , Figure 6 In this embodiment, the grinding mechanism includes a first motor 31, which is fixedly connected to the right side of the work platform 1. A first threaded rod 32 is fixedly connected to the output end of the first motor 31, and the first threaded rod 32 is rotatably connected inside the work platform 1. A sliding seat 33 is threadedly connected to the outer side of the first threaded rod 32, and the sliding seat 33 is slidably connected inside the work platform 1. A second motor 34 is fixedly connected to the top of the sliding seat 33, and a second threaded rod 35 is fixedly connected to the output end of the second motor 34. The second threaded rod 35 is rotatably connected inside the sliding seat 33, and the outer side of the second threaded rod 35 is threadedly connected to the output end of the second motor 34. A threaded sliding bracket 36 is provided, which is slidably connected inside the sliding seat 33. A grinding wheel body 37 is provided inside the sliding bracket 36. The position of the sliding bracket 36 and the grinding wheel body 37 can be adjusted by sliding the sliding seat 33, thereby dressing and grinding multiple clamped workpieces, thus improving the overall grinding efficiency. A groove is provided in the sliding seat 33 at the relative position of the sliding bracket 36. The sliding bracket 36 is slidably connected inside the groove. The groove allows the sliding bracket 36 to slide linearly inside the sliding seat 33, preventing the sliding bracket 36 from tilting and affecting the grinding wheel body 37 to perform grinding work.

[0024] During operation, the workpiece is placed on the placement table 21, and then the worm gear 29 is rotated to make the worm 28 rotate inside the work platform 1. When the worm 28 rotates, it cooperates with the first knob 210 to make the rotating disk 22 rotate inside the work platform 1. When the rotating disk 22 rotates, it cooperates with the first fixed rod 23, the second fixed rod 25 and the connecting rod 26 to drive the sliding block 24 to slide inward, so that the clamping block 27 contacts the workpiece, thereby clamping the workpiece. After the workpiece is clamped, the first motor 31 drives the first threaded rod 32 to rotate. The rotation of the first threaded rod 32 causes the sliding seat 33 to slide inside the work platform 1. This allows the sliding seat 33 to be adjusted to the desired position. Then, the second motor 34 operates to rotate the second threaded rod 35. When the second threaded rod 35 rotates, it drives the sliding bracket 36 to slide inside the sliding seat 33, thereby causing the grinding wheel body 37 to move closer to the surface of the workpiece. The grinding wheel body 37 then operates to grind and trim the workpiece. During grinding and trimming, the first fan 212 operates to provide suction. The air is filtered by the filter plate body 213 and then blown to the workpiece, causing the air and debris to flow. The debris then falls into the collection hopper 215 through the through hole inside the work platform 1 for centralized storage, which is convenient for the staff to process it later.

[0025] By adding a rotating disk 22, a first fixing rod 23, a second fixing rod 25, and a connecting rod 26 through the above steps, the problem of workpiece centering cannot be guaranteed due to deviation in the clamping position. When the deviation is large, it will cause some areas to be under-trimmed and require secondary grinding and trimming.
