Description

Technical Field

[0001] The invention belongs to the technical field of metal casting processing, and in particular relates to a metal casting surface grinding processing mechanism. Background Art

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed, so it can be machined without or with a small amount of processing, which reduces costs and time to a certain extent. Casting is one of the basic processes in the modern machinery manufacturing industry. Since casting can only achieve the molding of simple structures, after casting some complex metal parts, the casting needs to be further processed, including boring, milling, turning, grinding, cutting and other methods.

[0003] There are two methods for surface grinding of metal castings: manual grinding and mechanical grinding. Mechanical grinding or manual grinding can be used for regular surfaces, while some dead corners or irregular surfaces can only be polished manually through machines or sandpaper. However, the existing mechanical grinding equipment has a relatively single function during grinding, which limits its scope of application. At the same time, manual grinding cannot control the grinding force of metal castings, resulting in uneven grinding. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a surface grinding treatment mechanism for metal castings.

[0005] The technical solution adopted to solve the above technical problems is: to provide a metal casting surface grinding processing mechanism, including a workbench, a linear motor assembly is fixedly connected to one side of the top of the workbench, a limit plate corresponding to the linear motor assembly is fixedly connected to one side of the top of the workbench, and a vertical moving mechanism is installed at the output end of the linear motor assembly;

[0006] One end of the vertical moving mechanism is rotatably connected to a rotary drive mechanism, and two grinding drive mechanisms and two corresponding auxiliary pressurizing mechanisms are slidably connected to the rotary drive mechanism. A metal casting to be processed is arranged on the top of the workbench at a side away from the linear motor assembly.

[0007] Furthermore, the vertical moving mechanism includes a connecting square tube installed at the output end of the linear motor assembly, and both ends of the connecting square tube are fixedly connected with a counterweight block and a connecting piece, and the front end face and the rear end face of the connecting piece are fixedly connected with a plurality of first fixing ears.

[0008] Through the above technical solution, the rotation drive mechanism can be fixed in the horizontal and vertical directions through multiple first fixing ears, and the rotation drive mechanism can be raised and lowered by driving the connected square tube up and down through the linear motor assembly so as to adjust to the appropriate grinding position, wherein the counterweight block is used to prevent the rotation drive mechanism and the grinding drive mechanism connected to the other end connector from causing a large tilting force on the connected square tube.

[0009] Furthermore, a through hole corresponding to the limiting plate is opened on the connecting square tube, and the number of the plurality of first fixing ears is four, and they are distributed in pairs in the vertical and horizontal directions.

[0010] Through the above technical solution, the through hole ensures the limited sliding of the connected square tube, and the four first fixing ears are distributed in pairs to complete the fixation of the rotary drive mechanism in the horizontal and vertical directions.

[0011] Furthermore, the rotation drive mechanism includes two side rotating shafts, a first motor fixing shell is fixedly connected between the two side rotating shafts, the two side rotating shafts are fixedly connected with a locking block on the side away from the first motor fixing shell, fixing pins are arranged between the two locking blocks and the vertical moving mechanism, a supporting bearing frame plate is fixedly connected to one side of the first motor fixing shell, a first driving motor is installed inside the first motor fixing shell, a rotation limit shell is fixedly connected to one side of the supporting bearing frame plate, a rotating disk is rotatably connected to the inner wall of the rotating limit shell, a plurality of rolling steel balls are arranged between the rotating limit shell and the rotating disk, and a supporting guide frame is fixedly connected to the other side of the rotating disk.

[0012] Through the above technical scheme, when grinding the circular shell metal casting, the first drive motor drives the rotating disk to rotate, and completes the rotation support by rotating the limit shell and multiple rolling steel balls, thereby driving the support guide frame to rotate, thereby driving the two sets of grinding drive mechanisms and the auxiliary pressure mechanism to rotate, and starting to grind the inner wall of the metal casting. When grinding the flat surface of the metal casting, the two fixed pins are removed, and the overall rotating drive mechanism is rotated to make it in a horizontal position, and then the two fixed pins are horizontally inserted again to complete the limit fixation. The first drive motor drives the support guide frame to swing back and forth, thereby driving the two grinding drive mechanisms to realize the surface grinding of the metal casting.

[0013] Furthermore, the outer wall of the output shaft of the first drive motor is fixed to the inner wall of the bearing in the supporting bearing frame plate, and the output end of the first drive motor and the rotating disk are fixedly connected, and the inner wall of the rotating limit shell and the outer wall of the rotating disk are both provided with grooves corresponding to multiple rolling steel balls.

[0014] Through the above technical solution, the stability of the output shaft of the first drive motor is ensured by supporting the bearing frame plate, and at the same time, multiple rolling steel balls realize the rotation support of the rotating disk.

[0015] Furthermore, the grinding drive mechanism includes a sliding sleeve block slidably connected to the rotation drive mechanism, a plurality of fixed screws are fixedly connected to one side of the sliding sleeve block, a rotating support frame and a second motor fixing shell are respectively installed on the plurality of fixed screws, the other ends of the plurality of fixed screws are spirally connected with a first locking nut, a second driving motor is installed on the inner wall of the second motor fixing shell, two supporting limit bearings are installed inside the sliding sleeve block, a connecting square rod is fixedly connected to the output end of the second driving motor, an outer wall of the connecting square rod is fixedly connected to the limiting sleeve shell on the side close to the second driving motor, a triangular indicator block is fixedly connected to the top of the other end of the connecting square rod, and the connecting square One end of the rod passes through the limit rod, and both ends of the limit rod are provided with bolt assemblies. The outer wall of the connecting square rod is slidably connected with an extension square tube, and one end of the extension square tube is fixedly connected with a supporting disk at the internal position of the limit sleeve, and a first pressure spring is fixedly connected between one side of the support disk and the inner wall of the limit sleeve. One side of the front end face and the rear end face of the extension square tube are fixedly connected with a second fixing ear, and a scale is provided on the top of the extension square tube, and one end of the extension square tube is fixedly connected with a mounting chuck, and a grinding block is installed on the extension square tube. The rotating support frame is fixedly connected with two rotating support rods on the side away from the sliding sleeve block, and a scale bar is fixedly connected to the bottom center of the sliding sleeve block.

[0016] Through the above technical scheme, when grinding the circular shell metal casting, after adjusting the distance of the sliding sleeve block, the two rotating support rods on one side of the rotating support frame are rotated to the two ends of the limit rod, and the bolt assembly is used to penetrate the limit rod, the rotating support rod and the extended square tube respectively to fix the three, so as to avoid sliding of the connecting square rod and the extended square tube during grinding, and also avoid rotation of the extended square tube, thereby affecting the grinding effect. The grinding drive mechanism and the auxiliary pressure mechanism fixed at the bottom are rotated to the top, and the other set of grinding drive mechanism and auxiliary pressure mechanism are fixed and adjusted in the same way. After the adjustment is completed, grinding is started by driving the rotating drive mechanism. When grinding the flat surface of the metal casting, the fixation of the extended square tube is released. At this time, the linear motor assembly drives the connecting square tube to descend until the grinding block fits the metal casting, and then the linear motor assembly drives the connecting square tube to continue to descend. At this time, it will drive the limit sleeve to compress the first pressure spring, and apply pressure to the grinding block through the first pressure spring, and then apply pressure to the metal casting through the grinding block. At the same time, the connecting square rod slides in the extended square tube, and the pressure is determined by the distance the triangular indicator block moves on the scale. Then the second drive motor is energized, and the connecting square rod is driven by the second drive motor to drive the extended square tube and the grinding block to rotate and start grinding. At the same time, the first drive motor drives the supporting guide frame to swing back and forth, thereby realizing the surface grinding of the metal casting.

[0017] Furthermore, a bearing is installed on the rotating support frame, and a square hole limit block corresponding to the extended square tube is fixedly connected to the inner wall of the bearing, and rectangular through holes corresponding to the limit rod and the triangular indicator block are respectively opened on the extended square tube.

[0018] Through the above technical solution, the rotating support frame ensures the stable rotation of the extended square tube, the rectangular through hole ensures that the limit rod can pass through the extended square tube, and the moving distance of the triangular indicator block on the scale can be observed through the through hole.

[0019] Furthermore, the auxiliary pressurizing mechanism includes a sliding plate slidably connected to the rotary drive mechanism, the centers of the front and rear end surfaces of the sliding plate are fixedly connected with fixing studs, the other ends of the two fixing studs are spirally connected with a second locking nut, and the top of the sliding plate is fixedly connected with two return springs.

[0020] Through the above technical scheme, when grinding the circular shell metal casting, first place the support guide frame in a vertical position, and then make the bottom grinding drive mechanism naturally contact the inner wall of the metal casting, and then push the sliding plate in the auxiliary pressure mechanism corresponding to the grinding drive mechanism downward to compress the reset spring and then generate pressure on the overall grinding drive mechanism, so that the grinding drive mechanism starts to generate pressure on the inner wall of the metal casting, and the size of the pressure is determined by the moving distance of the sliding plate on the scale bar. After the movement, rotate the two second locking nuts and the support guide frame to generate friction to achieve fixation, so as to generate a fixed pressure on the inner or outer wall of the metal casting. When grinding the plane of the metal casting, move the overall grinding drive mechanism to one end of the support guide frame, and then push the sliding plate to squeeze the overall grinding drive mechanism through the reset spring, so that the grinding drive mechanism is fixed to one end of the support guide frame to avoid affecting the subsequent plane grinding effect.

[0021] Furthermore, a through hole corresponding to the scale bar is opened in the center of the sliding plate.

[0022] Through the above technical solution, the sliding plate determines the moving distance by sliding the through hole on the scale bar, and further determines the pressure of the grinding block on the metal casting.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention designs a grinding drive mechanism and an auxiliary pressure mechanism, so that when grinding a circular shell metal casting, the grinding drive mechanism at the bottom naturally contacts the inner wall of the metal casting, and then pushes downward the sliding plate in the auxiliary pressure mechanism corresponding to the grinding drive mechanism, thereby compressing the reset spring and generating pressure on the entire grinding drive mechanism, so that the grinding drive mechanism begins to generate pressure on the inner wall of the metal casting, and the size of the pressure is determined by the moving distance of the sliding plate on the scale bar. When grinding the plane of the metal casting, the linear motor assembly drives the connected square tube to descend, which in turn drives the limit sleeve to compress the first pressure spring, and applies pressure to the grinding block through the first pressure spring, thereby The pressure is applied to the metal casting by means of a grinding block, while the connecting square rod slides in the extending square tube, and the pressure is determined by the distance the triangular indicator block moves on the scale, thereby achieving control over the grinding force when grinding both the circular shell metal casting and the flat metal casting, thereby ensuring a uniform grinding effect; (2) The present invention is suitable for grinding a variety of metal castings by designing a grinding drive mechanism and an auxiliary pressure mechanism, such as grinding the inner and outer walls of a circular shell casting, and grinding the flat part of the metal casting, thereby increasing the scope of application, and at the same time, with the cooperation of the connecting piece and the rotating drive mechanism, horizontal and vertical fixed locking is achieved, thereby achieving two types of grinding.

The inner wall of the rotating limit shell 507 and the outer wall of the rotating disk 508 are provided with grooves corresponding to multiple rolling steel balls 509. The stability of the output shaft of the first drive motor 506 is guaranteed by the supporting bearing frame plate 505. At the same time, multiple rolling steel balls 509 realize the rotation support of the rotating disk 508.

[0042] like Figure 1-Figure 14As shown, two grinding drive mechanisms 6 and two corresponding auxiliary pressurizing mechanisms 7 are respectively slidably connected to the rotation drive mechanism 5, and the grinding drive mechanism 6 includes a sliding sleeve block 601 slidably connected to the rotation drive mechanism 5, and a plurality of fixed screws 602 are fixedly connected to one side of the sliding sleeve block 601, and a rotation support frame 603 and a second motor fixed shell 604 are respectively installed on the plurality of fixed screws 602, and the other ends of the plurality of fixed screws 602 are all spirally connected with a first locking nut 605, and the inner wall of the second motor fixed shell 604 is installed with a second drive motor 606, and two support limit bearings 607 are installed inside the sliding sleeve block 601, and the output end of the second drive motor 606 is fixedly connected with a connecting square rod 608, and the outer wall of the connecting square rod 608 is close to the One side of the second driving motor 606 is fixedly connected to a limit sleeve 609, and a triangular indicator block 610 is fixedly connected to the top of the other end of the connecting square rod 608. One end of the connecting square rod 608 passes through a limit rod 611, and bolt assemblies 612 are provided at both ends of the limit rod 611. An extension square tube 613 is slidably connected to the outer wall of the connecting square rod 608, and one end of the extension square tube 613 is fixedly connected to a support disc 614 at an inner position of the limit sleeve 609. A first pressure spring 615 is fixedly connected between one side of the support disc 614 and the inner wall of the limit sleeve 609. A second fixing ear 616 is fixedly connected to one side of the front end face and the rear end face of the extension square tube 613. A scale 617 is provided on the top of the extension square tube 613.

The bottom center of the sliding sleeve block 601 is fixedly connected with a scale bar 621. When grinding the circular shell metal casting, after adjusting the distance of the sliding sleeve block 601, the two rotating support rods 620 on one side of the rotating support frame 603 are rotated to the two ends of the limit rod 611, and the bolt assembly 612 is used to penetrate the limit rod 611, the rotating support rod 620 and the extended square tube 613 respectively to fix the three, so as to avoid sliding of the connecting square rod 608 and the extended square tube 613 during grinding, and also to avoid rotation of the extended square tube 613, thereby affecting the grinding effect. , rotate the grinding drive mechanism 6 and the auxiliary pressure mechanism 7 fixed at the bottom to the top, and similarly, fix and adjust the other set of grinding drive mechanism 6 and the auxiliary pressure mechanism 7. After the adjustment is completed, start grinding by driving the rotating drive mechanism 5 (at this time, the two second drive motors 606 are not connected to the cable, so they can rotate freely). When grinding the plane of the metal casting, release the fixation of the extended square tube 613. At this time, the linear motor assembly 2 drives the connecting square tube 401 to descend until the grinding block 619 fits the metal casting, and then the linear motor assembly 2 drives the connecting square tube 401 to continue to descend. At this time, it will drive the limiting sleeve 609 to compress the first pressure spring 615, and the first pressure spring 615 will apply pressure to the grinding block 619.Then, the grinding block 619 is used to apply pressure to the metal casting. At the same time, the connecting square rod 608 slides in the extending square tube 613, and the pressure is determined by the distance that the triangular indicator block 610 moves on the scale 617. Then, the second drive motor 606 is powered on, and the connecting square rod 608 is driven by the second drive motor 606 to drive the extending square tube 613 and the grinding block 619 to rotate and start grinding.

The rectangular through hole ensures that the stopper rod 611 can pass through the extended square tube 613, and the moving distance of the triangular indicator block 610 on the scale 617 can be observed through the through hole.

[0043] like Figure 1-Figure 14 As shown, the auxiliary pressure mechanism 7 includes a sliding plate 701 slidably connected to the rotating drive mechanism 5, and the centers of the front and rear end surfaces of the sliding plate 701 are fixedly connected with fixed studs 702, and the other ends of the two fixed studs 702 are spirally connected with second locking nuts 703, and the top of the sliding plate 701 is fixedly connected with two return springs 704. When grinding the circular shell metal casting, first put the support guide frame 510 in a vertical position, and then make the bottom grinding drive mechanism 6 naturally contact the inner wall of the metal casting, and then push the sliding plate 701 in the auxiliary pressure mechanism 7 corresponding to the grinding drive mechanism 6 downward to compress the return spring 704 and then generate pressure on the entire grinding drive mechanism 6, so that the grinding drive mechanism 6 begins to generate pressure on the inner wall of the metal casting, and the movement distance of the sliding plate 701 on the scale bar 621 is determined. The size of the fixed pressure is determined. After moving, the two second locking nuts 703 and the supporting guide frame 510 are rotated to generate friction to achieve fixation, so as to generate a fixed pressure on the inner wall or outer wall of the metal casting. When grinding the plane of the metal casting, the overall grinding drive mechanism 6 is moved to one end of the supporting guide frame 510, and then the sliding plate 701 is pushed and then the reset spring 704 is used to squeeze the overall grinding drive mechanism 6, so that the grinding drive mechanism 6 is fixed to one end of the supporting guide frame 510 to avoid affecting the subsequent plane grinding effect. A through hole corresponding to the scale bar 621 is opened in the center of the sliding plate 701. The sliding plate 701 determines the moving distance by sliding the through hole on the scale bar 621, and then determines the pressure of the grinding block 619 on the metal casting. A metal casting 8 to be processed is arranged on the top of the workbench 1 on the side away from the linear motor assembly 2.

[0044] The working principle of this embodiment is as follows. When grinding a metal casting with a circular shell structure, the support guide frame 510 is first placed in a vertical position, and then the grinding drive mechanism 6 at the bottom is naturally in contact with the inner wall of the metal casting, and then the sliding plate 701 in the auxiliary pressure mechanism 7 corresponding to the grinding drive mechanism 6 is pushed downward to compress the return spring 704 and then generate pressure on the entire grinding drive mechanism 6, so that the grinding drive mechanism 6 begins to generate pressure on the inner wall of the metal casting, and the sliding plate 701 is moved on the scale bar 621. The size of the pressure is determined by the moving distance. After the movement, the two second locking nuts 703 and the support guide frame 510 are rotated to generate friction to achieve fixation. At the same time, the two rotating support rods 620 on one side of the rotating support frame 603 are rotated to the two ends of the limit rod 611, and the bolt assembly 612 is used to penetrate the limit rod 611, the rotating support rod 620 and the extended square tube 613 respectively to achieve the fixation of the three, so as to avoid the sliding of the connecting square rod 608 and the extended square tube 613 during grinding, and also to avoid the rotation of the extended square tube 613, thereby affecting To achieve the desired grinding effect, the grinding drive mechanism 6 and the auxiliary pressure mechanism 7 fixed at the bottom are rotated to the top. Similarly, the other set of grinding drive mechanism 6 and the auxiliary pressure mechanism 7 are fixed and adjusted. After the adjustment is completed, the first drive motor 506 drives the rotating disk 508 to rotate, and completes the rotation support by rotating the limit shell 507 and a plurality of rolling steel balls 509, thereby driving the support guide frame 510 to rotate, thereby driving the two sets of grinding drive mechanisms 6 and the auxiliary pressure mechanism 7 to rotate, and starting to grind the inner wall of the metal casting, while pushing the machine to be processed. The inner wall of the metal casting 8 can be polished. When the outer wall of the metal casting 8 to be processed is polished, the outer wall can be polished in the same way. At the same time, when polishing, the compression return spring 704 or the stretch return spring 704 can be used to apply pressure according to the diameter of the metal casting 8 to be processed. If the diameter of the metal casting 8 to be processed is large, the stretch return spring 704 is used to apply pressure to the metal component. On the contrary, if the diameter of the metal casting 8 to be processed is small, the compression return spring 704 is used to apply pressure to the metal component.

[0045] When grinding the plane of a metal casting, first place the metal casting on the top of the workbench 1, then remove the two bolt assemblies 612 and the two fixing pins 504, rotate the overall rotating drive mechanism 5 to make it in a horizontal position, and then horizontally insert the two fixing pins 504 again to complete the limit fixation, move the overall grinding drive mechanism 6 to one end of the supporting guide frame 510, and then push the sliding plate 701 and then squeeze the overall grinding drive mechanism 6 through the reset spring 704, so that the grinding drive mechanism 6 is fixed to one end of the supporting guide frame 510, and the fixation is completed by the engagement of the two first fixing ears 404 and the locking block 503. At this time, the connecting square tube 401 is driven down by the linear motor assembly 2 until the grinding block 619 fits the metal casting, and then the linear motor assembly 2 drives the connecting square tube 401 to continue to descend, at which time it will drive the limit sleeve The shell 609 compresses the first pressure spring 615, and the first pressure spring 615 is used to apply pressure to the grinding block 619, and then the grinding block 619 is used to apply pressure to the metal casting. At the same time, the connecting square rod 608 slides in the extended square tube 613, and the pressure is determined by the distance that the triangular indicator block 610 moves on the scale 617. Then the second drive motor 606 is energized, and the connecting square rod 608 is driven by the second drive motor 606 to drive the extended square tube 613 and the grinding block 619 to rotate and start grinding. At the same time, the first drive motor 506 drives the supporting guide frame 510 to swing back and forth, thereby realizing the surface grinding of the metal casting. When grinding, you only need to push the metal casting to complete the grinding of the entire surface. When grinding a flat surface, you can choose to use a single or double set of grinding drive mechanisms 6 and auxiliary pressure mechanisms 7 for grinding.
