Description

Technical Field

[0001] This utility model relates to the field of grinding devices, specifically to a grinding device for the surface of aluminum die castings. Background Technology

[0002] In industrial production, aluminum die castings are widely used in the automotive, aerospace, and electronics industries, and their surface quality directly affects the appearance and performance of the products.

[0003] Automated grinding equipment improves grinding efficiency and quality stability to a certain extent. Common automated grinding equipment includes a robotic arm with a fixed grinding head and an automatic rotating worktable. When in use, the multi-axis motion of the robotic arm imitates the action of a human hand to achieve grinding of different parts of the end face and side of the casting.

[0004] However, during the grinding process of castings, clamping tools are required to hold and fix the castings to prevent them from loosening or shifting during the grinding process. Currently, clamping tools mainly include triangular claw discs, screw-type push clamps, and pneumatic cylinder clamps. These clamps can hold and fix the tools well.

[0005] However, once the tool is clamped and fixed, only one end face will face upwards to be ground by the grinding equipment, while the other end face faces downwards and cannot be ground. Furthermore, when the casting is clamped on both sides, the clamped part of the casting cannot be ground when the side of the casting needs to be ground. When both end faces need to be ground, one can only wait until one end face is ground before releasing the clamp, then manually flipping the casting, and finally using the clamp to hold and fix the casting. When grinding the side, one can only repeatedly release and fix the clamp to adjust the position of the casting, which is quite inconvenient.

[0006] Therefore, it is necessary to invent a surface grinding device for aluminum die castings. Utility Model Content

[0007] The purpose of this invention is to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a surface grinding device for aluminum die castings, including a worktable and a robotic arm disposed on one side of the worktable. One end of the robotic arm is connected to a grinding device. A placement component is disposed above the worktable. Translation components are symmetrically installed at both ends of the worktable. A clamping component is slidably connected to one side of each of the two translation components.

[0009] Based on the above features: the placement components are set into two groups. When the casting is placed on top of one of the placement components, the translation component will drive the clamping component to move to both sides of the placement component where the casting is placed, so that the clamping component can clamp and fix the casting from both sides. Then, the robotic arm can adjust the orientation and height of the grinding equipment to grind the upper end face of the casting. After grinding, the translation component can drive the clamping component and the casting to move to top of the other placement component. During this process, the casting will be flipped 180 degrees, so that the ground end face is facing down and the unground end face is facing up. Finally, the unground end of the casting can be ground again using the grinding equipment.

[0010] Preferably, the placement assembly includes a placement platform and a central hole in the middle of the placement platform. A rotary motor is disposed inside the central hole, and a turntable is rotatably connected above the rotary motor.

[0011] Based on the above characteristics: when the rotary motor drives the turntable to rotate, the casting placed on top of the turntable will rotate synchronously.

[0012] Preferably, the translation component includes a rodless cylinder and a protruding tooth disposed at the middle of the upper end of the rodless cylinder, and a slider is slidably connected to one side of the rodless cylinder.

[0013] Based on the above characteristics, when the rodless cylinder starts, it can drive the slider to move back to the reset position.

[0014] Preferably, the clamping assembly includes a base and a connecting seat fixedly connected to the upper end of the base. A fixing seat is provided at one end of the connecting seat, and a clamping plate is connected to the end of the fixing seat away from the connecting seat.

[0015] Based on the above characteristics: when the slider slides back and forth, it can drive the connecting seat, fixed seat and clamping plate to move synchronously through the base.

[0016] Preferably, the connecting seat has bearing seats symmetrically arranged at both ends, a drive shaft is movably connected in the middle of the bearing seats, and a gear is connected to the end of the drive shaft away from the fixed seat.

[0017] Based on the above characteristics: when the gear and the tooth mesh, the fixed seat and the clamp can be rotated 180 degrees through the transmission shaft.

[0018] Preferably, a miniature cylinder is installed in the inner cavity of the fixed base, the movable end of the miniature cylinder is connected to a protective shell, and a roller is rotatably connected in the middle of the protective shell.

[0019] Based on the above features: when it is necessary to grind the two ends of the casting, the miniature cylinder can drive the roller to retract into the inner cavity of the clamping plate; when it is necessary to grind the side of the casting, the miniature cylinder can drive the roller to extend outward, so that the roller makes rolling contact with the side of the casting; when the rotary motor drives the turntable to rotate, the turntable will drive the casting above to rotate synchronously. At this time, rolling friction will be formed between the casting and the roller, which facilitates the comprehensive grinding of the side of the casting.

[0020] Preferably, a groove is provided between the fixing seat and the clamping plate.

[0021] Based on the above features, it is convenient to accommodate the miniature cylinder, protective shell and roller between the fixed seat and the inner cavity of the clamping plate.

[0022] The beneficial effects of this utility model are:

[0023] 1. By setting up translation and clamping components, the upper and lower end faces of the casting can be ground. When the casting is placed on one of the placement components, the clamping component will use clamping plates to clamp and fix the casting on both sides. Then, the robotic arm can adjust the position and height of the grinding equipment to grind the upper end face of the casting. After grinding, the translation component can move the clamping component and the casting to the other placement component. During this process, the gear will pass over the convex tooth. At this time, the gear and the convex tooth will mesh. The gear will drive the fixed seat and clamping plate to rotate 180 degrees through the transmission shaft, so that the ground end face is facing down and the unground end face is facing up. Finally, the grinding equipment can be used again to grind the unground end of the casting without manual flipping.

[0024] 2. The turntable and rollers allow for grinding of the sides of the casting. When grinding the two ends of the casting is required, the miniature cylinder can retract the rollers into the inner cavity of the clamping plate. When grinding the sides of the casting is required, the grinding equipment can be lowered to one side of the casting so that the side of the grinding wheel contacts the side of the casting. Then, the miniature cylinder can drive the rollers to extend outward so that the rollers roll into contact with the side of the casting. Since the bottom of the casting is placed on the placement platform and the turntable, when the rotary motor drives the turntable to rotate, the turntable will drive the casting above to rotate synchronously. At this time, rolling friction will be formed between the casting and the rollers, which facilitates the comprehensive grinding of the sides of the casting. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] See attached document Figure 1-4 This utility model provides a surface grinding device for aluminum die castings, including a worktable 1 and a robotic arm 2 installed on one side of the worktable 1. This is an existing technology device, and is only shown in the illustrations in this application. The specific model, structure, and working principle are not described in detail. You can choose from existing equipment as needed. One end of the robotic arm 2 is connected to a grinding device 3. The grinding device 3 mainly includes a mounting base, a grinding motor (model AF53B), a drive shaft, and a grinding wheel. The mounting base is fixed to one end of the robotic arm 2 by bolts. A hole is opened in the middle of the mounting base. The grinding motor is fixed above the mounting base by bolts. The drive shaft is connected to the output end of the grinding motor and moves through the hole in the middle of the mounting base. The lower end of the drive shaft is fixed to the grinding wheel by bolts. When the grinding motor is started, the grinding wheel can be rotated by the drive shaft. The robotic arm 2 can adjust the position and height of the grinding device 3.

[0033] A placement assembly 4 is installed above the workbench 1. The placement assembly 4 includes a placement platform 41, which is symmetrically arranged in two sets. Translational assemblies 5 are symmetrically installed at both ends of the workbench 1. Clamping assemblies 6 are slidably connected to one side of each translational assembly 5. Each translational assembly 5 includes a rodless cylinder 51 and a protruding tooth 52 at the center of its upper end. A slider 53 is slidably connected to one side of the rodless cylinder 51. When the rodless cylinder 51 is powered on, it can drive the slider 53 to move back to its original position. Because there are two sets of rodless cylinders 51, it may not be possible to... It ensures that the two sets of clamping components 6 are moved synchronously, but only the two sets of clamping components 6 need to be roughly moved, which will not affect the overall operation. The rodless cylinder 51 has symmetrical connecting handles on both sides of its lower end. The worktable 1 has symmetrical guide grooves on both sides of its surface, and the worktable 1 is hollow inside. Opposing displacement devices (such as positive and negative screws, guide rails, etc. are not limited and can be set according to needs) can be set below the guide grooves to facilitate the two sets of translation components 5 and clamping components 6 to move in opposite directions above the worktable 1 through the corresponding displacement devices.

[0034] The clamping assembly 6 includes a base 61 and a connecting seat 62 fixedly connected to the upper end of the base 61. The base 61 is fixed to one side of the slider 53. A fixed seat 63 is provided at one end of the connecting seat 62. When the slider 53 moves back and forth, the connecting seat 62 and the fixed seat 63 can be moved synchronously through the base 61. Bearing seats 621 are symmetrically provided at both ends of the connecting seat 62. A drive shaft 622 is movably connected in the middle of the bearing seats 621. One end of the drive shaft 622 is fixedly connected to the fixed seat 63. A gear 623 is connected to the end of the drive shaft 622 away from the fixed seat 63. The gear 623 is located above the rodless cylinder 51. A clamping plate 64 is connected to the end of the fixed seat 63 away from the connecting seat 62, which facilitates clamping and fixing the casting (aluminum die casting) on ​​both sides.

[0035] Based on the above structural effects, this application includes the following embodiments:

[0036] When the rodless cylinder 51 drives the slider 53 to move the two sets of clamping components 6 to one side, the two sets of clamping components 6 will be positioned above one of the placement platforms 41. Then, the robotic arm 2 can adjust the orientation and height of the grinding equipment 3 to grind the upper surface of the casting. After the upper surface of the casting is ground, the rodless cylinder 51 will drive the slider 53 to move the two sets of clamping components 6 to the other side (the upper surface of the grinding casting will move synchronously). During this process, the gear 623 will pass over the convex tooth 52. At this time, the gear 623 and the convex tooth 52 will be in contact. 2. When meshing occurs, gear 623 will drive fixed seat 63 and clamping plate 64 to rotate 180 degrees through transmission shaft 622 (base 61 and connecting seat 62 are fixed). When the casting is clamped in the middle of clamping plate 64, the casting will also rotate 180 degrees. When the casting is moved above another placement platform 41, the displacement can be stopped. At this time, the end face of the casting that was originally facing down will be flipped to the upper end face (the end face of the casting that was originally facing up after grinding will be flipped to the lower end face). At this time, the un-grinded end of the casting can be ground again using grinding equipment 3.

[0037] See attached document Figure 1 , Figure 2 and Figure 5 This utility model provides a surface grinding device for aluminum die castings. The placement table 41 has a central hole 42 in the middle, and the worktable 1 has a circular hole in the middle. There are two symmetrical placement tables 41. The central hole 42 between the two placement tables 41 is aligned with the circular hole in the middle of the worktable 1, and the two holes have the same diameter. A rotary motor 43 (model SIZE14) is provided inside the central hole 42. The lower half of the rotary motor 43 is fixed in the inner cavity of the worktable 1. A turntable 44 is rotatably connected above the rotary motor 43. When the rotary motor 43 is started, it can drive the turntable 44 to rotate.

[0038] A miniature cylinder 631 (model MCE-20T) is installed inside the fixed base 63. The movable end of the miniature cylinder 631 is connected to a protective shell 632. The protective shell 632 has a transverse U-shaped structure. A roller 633 is rotatably connected in the middle of the protective shell 632. A rotating shaft is movably sleeved in the middle of the roller 633. The two ends of the rotating shaft are connected and fixed to the two ends of the protective shell 632. A groove is opened between the fixed base 63 and the clamping plate 64 to facilitate the extension and retraction adjustment of the roller 633. When the roller 633 extends and contacts the side of the casting, rolling friction will be formed between the roller 633 and the casting.

[0039] Based on the above structural effects, this application includes the following embodiments:

[0040] When grinding is required on both ends of the casting, the miniature cylinder 631 can drive the roller 633 to retract into the inner cavity of the clamping plate 64. At this time, the outer wall of the clamping plate 64 will be in fixed contact with the side of the casting, preventing the casting from moving. Then, the grinding equipment 3 can be lowered to grind the upper end of the casting. When grinding is required on the side of the casting, the grinding equipment 3 can be lowered to one side of the casting, so that the side of the grinding wheel contacts the side of the casting. Subsequently, the miniature cylinder 631 can drive the roller 633 to extend outward, so that the roller... The roller 633 makes rolling contact with the side of the casting. Since the bottom of the casting is placed on the placement platform 41 and the turntable 44, when the rotary motor 43 drives the turntable 44 to rotate, the turntable 44 will drive the casting above to rotate synchronously. At this time, rolling friction will be formed between the casting and the roller 633, which facilitates the full grinding of the side of the casting. (During the rotation grinding process, a limiting part can be set on the top of the casting to prevent the casting from being thrown out during the rotation. The specific setting can be made according to the needs, and this application does not make specific limitations.)

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
