Description

Technical Field

[0001] This utility model application relates to the field of mechanical polishing technology, specifically to a polishing and grinding equipment for machining. Background Technology

[0002] After casting is completed, the surface of the casting usually needs to be vigorously ground to reduce the surface roughness of the workpiece, so as to remove defects such as flash and burrs on the surface of the casting, and obtain a finished casting with good flatness that meets the high-quality requirements. When polishing the casting, the top and bottom usually need to be ground.

[0003] Chinese Patent Publication No. CN216327177U discloses a polishing and grinding equipment for machining, including a frame, a screw, a slider, a first motor, a grinding device, a worktable, a fixing device, and a dust collection device. By mounting the grinding device on the frame and allowing it to slide on the screw, its position can be adjusted according to the workpiece to be ground, making it more convenient to use. A dust collection port is provided on the side wall of the frame, with one end of a dust collection pipe connected to the port and the other end connected to a dust collection box, allowing for timely removal and collection of dust or debris generated during the grinding device's operation, reducing safety hazards to operators working in dusty environments for extended periods. The inclusion of a first grinding head and a second grinding head, each with its own separate drive mechanism, enables simultaneous grinding of multiple workpieces, resulting in high work efficiency; alternatively, the first motor can drive both heads to rotate simultaneously, grinding the inner wall of cylindrical workpieces, further enhancing its applicability.

[0004] The aforementioned device clamps the casting with a clamping plate and then uses a grinding head to grind the casting. However, the device can only grind the top of the casting. If the bottom of the casting needs to be ground, the casting must be removed, flipped over, and reinstalled, which reduces the overall grinding efficiency. Utility Model Content

[0005] To address the aforementioned problems, a polishing and grinding device for machining is provided. A hydraulic rod drives a clamping block to hold the casting, preventing it from wobbling during grinding. The top of the casting is then ground using a grinding tool. When grinding the bottom of the casting is required, an electric push rod moves a connecting frame, causing a rack at one end of the connecting frame to move as well. The rack drives a gear, which in turn rotates a rotating rod and a turntable. Simultaneously, the hydraulic rod on one side of the turntable and the clamped casting also rotate, facilitating the grinding of the bottom of the casting.

[0006] To address the problems in the existing technology, this utility model application provides a polishing and grinding equipment for machining, including a processing table, a grinding frame on the top of the processing table, support plates on both outer walls of the grinding frame, rotating rods rotatably mounted on both inner walls of the grinding frame, one end of the rotating rod extending to the outside of the grinding frame and equipped with a gear, a turntable at the other end of the rotating rod, a hydraulic rod on the side wall of the turntable, a clamping block for holding castings at the movable end of the hydraulic rod, a grinding component for grinding the castings inside the grinding frame, and a cooling and chip removal assembly inside the grinding frame.

[0007] Preferably, the top of the processing table is provided with a mounting plate, the top of the mounting plate is provided with an electric push rod, the telescopic end of the electric push rod is provided with a connecting frame, both ends of the connecting frame are provided with racks that mesh with gears, and the top of the support plate is provided with a moving groove for the racks to move.

[0008] Preferably, the cooling and chip removal assembly includes water storage cylinders disposed on the inner walls of both sides of the grinding frame. Spray pipes are connected to the sides of the two water storage cylinders that are close to each other. A piston push rod is movably disposed inside the water storage cylinder. One end of the piston push rod extends to the outside of the water storage cylinder and is provided with a squeezing block. A compression spring is sleeved on the outside of the piston push rod. One end of the compression spring is connected to the bottom of the water storage cylinder, and the other end of the compression spring is connected to the top of the squeezing block. A protrusion for abutting the squeezing block is provided on the outside of the turntable.

[0009] Preferably, the top of the grinding frame is provided with a water tank, and both sides of the water tank are connected to water inlet pipes, the other end of which is connected to the inside of the water storage cylinder.

[0010] Preferably, a first one-way valve is provided inside the water inlet pipe, and a second one-way valve is provided inside the spray pipe.

[0011] Preferably, a collection frame for collecting wastewater and waste debris is movably provided on the top of the processing table.

[0012] The advantages of this utility model application compared to the prior art are:

[0013] 1. The casting is clamped by a hydraulic rod to prevent it from shaking during grinding. The top of the casting is then ground. When the bottom of the casting needs to be ground, the connecting frame is moved by an electric push rod. The rack at one end of the connecting frame also moves, which drives the gear to rotate, further rotating the rotating rod and the turntable. At the same time, the hydraulic rod on one side of the turntable and the clamped casting also rotate, making it easier for the grinding tool to grind the bottom of the casting.

[0014] 2. By using the protrusion to abut against the extrusion block, the extrusion block and piston rod move upward, which can spray the water inside the water tank out of the spray pipe. The sprayed water can cool down the casting and prevent the casting from generating high temperatures during grinding, which would affect the later work. At the same time, the sprayed water can remove the debris generated during grinding, causing it to fall into the collection box for easy later processing. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model application provides:

[0024] A polishing and grinding device for machining includes a processing table 1, a grinding frame 3 on the top of the processing table 1, support plates 11 on both outer walls of the grinding frame 3, rotating rods 16 rotatably mounted on both inner walls of the grinding frame 3, one end of the rotating rods 16 extending to the outside of the grinding frame 3 and equipped with a gear 9, and a turntable 17 at the other end of the rotating rods 16. A hydraulic rod 4 is mounted on the side wall of the turntable 17, and a clamping block 15 for clamping castings is mounted on the movable end of the hydraulic rod 4. A grinding component 8 for grinding castings is mounted inside the grinding frame 3, and a cooling and chip removal assembly is mounted inside the grinding frame 3.

[0025] The hydraulic rod 4 drives the clamping block 15 to clamp the casting, preventing it from shaking during grinding. Then, the grinding part 8 is used to grind the top of the casting. When the bottom of the casting needs to be ground, the rotating rod 16 and the turntable 17 rotate. At the same time, the hydraulic rod 4 on one side of the turntable 17 and the clamped casting also rotate, making it convenient for the grinding part 8 to grind the bottom of the casting, avoiding the need to reinstall the casting before grinding the bottom.

[0026] like Figure 3 As shown, the top of the processing table 1 is provided with a mounting plate 13, the top of the mounting plate 13 is provided with an electric push rod 14, the telescopic end of the electric push rod 14 is provided with a connecting frame 12, both ends of the connecting frame 12 are provided with racks 10 that mesh with the gear 9, and the top of the support plate 11 is provided with a moving groove for the racks 10 to move.

[0027] The electric push rod 14 drives the connecting frame 12 to move, and the rack 10 at one end of the connecting frame 12 will also move. The rack 10 can drive the gear 9 to rotate, which in turn drives the rotating rod 16 to rotate. At the same time, the moving groove on the support plate 11 prevents the rack 10 from shifting position during movement.

[0028] like Figure 5 and Figure 6 As shown, the cooling and chip removal assembly includes water storage cylinders 5 disposed on the inner walls of both sides of the grinding frame 3. Spray pipes 20 are connected to the sides of the two water storage cylinders 5 that are close to each other. A piston push rod 22 is movably disposed inside the water storage cylinder 5. One end of the piston push rod 22 extends to the outside of the water storage cylinder 5 and is provided with a pressing block 23. A compression spring 24 is sleeved on the outside of the piston push rod 22. One end of the compression spring 24 is connected to the bottom of the water storage cylinder 5, and the other end of the compression spring 24 is connected to the top of the pressing block 23. A protrusion 18 for abutting the pressing block 23 is provided on the outside of the turntable 17.

[0029] The protrusion 18 on the outside of the turntable 17 abuts against the extrusion block 23, causing the extrusion block 23 and the piston rod 22 to move upward. This allows the water inside the water tank 5 to be sprayed out from the spray pipe 20. The sprayed water can cool the casting and prevent the casting from generating high temperatures during grinding, which would affect subsequent work. At the same time, the sprayed water can remove the debris generated during grinding.

[0030] like Figure 5 As shown, a water tank 7 is provided on the top of the grinding frame 3. Water inlet pipes 6 are connected to both sides of the water tank 7, and the other end of the water inlet pipes 6 is connected to the inside of the water storage cylinder 5.

[0031] After the protrusion 18 disengages from the extrusion block 23, the piston rod 22 moves downward under the action of the compression spring 24, thereby replenishing the water inside the water tank 7 into the water storage cylinder 5, which facilitates the subsequent cooling and chip removal work.

[0032] like Figure 6 As shown, the inlet pipe 6 is equipped with a first one-way valve 19, and the spray pipe 20 is equipped with a second one-way valve 21.

[0033] When replenishing water to the water storage tank 5, the second one-way valve 21 prevents external air from entering the interior of the water storage tank 5, while the first one-way valve 19 prevents water inside the water storage tank 5 from flowing back into the water tank 7.

[0034] like Figure 1 As shown, a collection box 2 for collecting wastewater and waste debris is movably installed on the top of the processing table 1.

[0035] Wastewater and wastewater can be collected through collection box 2 for easy later treatment.

[0036] Working principle: When grinding and polishing a casting, the casting is first placed between two clamping blocks 15. Then, the hydraulic rod 4 drives the clamping blocks 15 to hold the casting, preventing it from shaking during grinding. The grinding element 8 is then used to grind the top of the casting. When grinding the bottom of the casting, the electric push rod 14 moves the connecting frame 12, causing the rack 10 at one end of the connecting frame 12 to move as well. The rack 10 drives the gear 9 to rotate, further rotating the rotating rod 16 and the turntable 17. Simultaneously, the hydraulic rod 4 on one side of the turntable 17 and the clamped casting also rotate, allowing the grinding element 8 to easily grind the bottom of the casting. As the disc 17 rotates, it also drives the external protrusion 18 to rotate. The protrusion 18 abuts against the pressing block 23, causing the pressing block 23 and the piston rod 22 to move upward. This allows the water inside the water storage tank 5 to be sprayed out from the spray pipe 20. The sprayed water can cool the casting and prevent the casting from generating high temperatures during grinding, which would affect subsequent work. At the same time, the sprayed water can remove the debris generated during grinding, causing it to fall into the collection frame 2 for easy processing later. When the protrusion 18 disengages from the pressing block 23, the piston rod 22 moves downward under the action of the compression spring 24, thereby replenishing the water inside the water tank 7 into the water storage tank 5, facilitating subsequent cooling and debris removal.
