Description

Technical Field

[0001] This utility model relates to the technical field of metal casting processing equipment, specifically to a floor-standing metal casting grinding wheel machine. Background Technology

[0002] A grinding wheel machine is a common piece of equipment used to sharpen various cutting tools and other tools. It is also used for grinding, deburring, and cleaning small parts. It mainly consists of a base, grinding wheel, electric motor or other power source, bracket, protective cover, and water supply. Grinding wheel machines can be categorized into handheld, vertical, suspended, and benchtop types. Castings are metal parts obtained through various casting methods. This involves pouring molten metal into a pre-prepared mold using methods such as pouring, injection, suction, or other casting techniques. After cooling and subsequent processing such as grinding, the resulting object has a specific shape, size, and properties.

[0003] Metal castings usually need to be polished after they have cooled. Most of the grinding machines on the market are fixed grinding wheels, which cannot adapt to castings of different heights. This results in low efficiency of the grinding wheels and affects subsequent use. Grinding metal castings will generate a lot of dust and debris. The dust will float in the air, causing pollution to the workshop environment. Moreover, workers who work in the workshop for a long time will inhale the dust and debris, which will pose a safety hazard to the workers' health. Utility Model Content

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-4 As shown, it illustrates a floor-standing metal casting grinding machine according to an embodiment of the present invention, including: a workbench 1, universal wheels 2 fixedly installed at the four corners of the lower end of the workbench 1, and a hydraulic rod 3 fixedly installed at the middle of the upper end of the workbench 1.

[0029] A fixing plate 4 is fixedly installed on the right side of the hydraulic rod 3, and a rack 5 is fixedly installed in the middle of the upper end of the fixing plate 4. Grooves 6 are fixedly opened on both sides of the rack 5, and a receiving rod 7 is slidably connected inside the groove 6. A gear 8 is rotatably connected between the two receiving rods 7. The top surface of the two receiving rods 7 is flush with the hydraulic rod 3, and the gear 8 and the rack 5 form a meshing connection.

[0030] For example, such as Figure 3 As shown, a device platform 9 is fixedly installed above the hydraulic rod 3, and a servo motor 10 is fixedly installed at the upper end of the device platform 9. Rotating rods 11 are rotatably connected to both sides of the servo motor 10. A sanding disc 12 is rotatably connected to the upper end of the rotating rods 11, and a protective cover 13 is fixedly connected to the outer end of the sanding disc 12. A spark block bracket 14 is fixedly connected above the protective cover 13, and a spark baffle 15 is fixedly connected to the upper left side of the spark block bracket 14.

[0031] For example, such as Figure 2 As shown, the workbench 1 is irregularly shaped, the casters 2 are heavy-duty casters with rear brakes, the grooves 6 are symmetrically installed on the front and rear sides of the fixed plate 4 with the fixed plate 4 as the center reference, and the top surface of the receiving rod 7 is in contact with the bottom surface of the device table 9 on both sides.

[0032] For example, such as Figure 3 As shown, the rotating rod 11 is symmetrically installed on the front and rear sides of the servo motor 10 with the servo motor 10 as the center reference. The rotating rod 11 is rotatably connected to the sand disc 12 through the servo motor 10. An opening is fixedly opened on the top of the protective cover 13. The spark block bracket 14 is connected to the protective cover 13 by a flange.

[0033] For example, such as Figure 3As shown, the upper end of the spark block bracket 14 is fixedly provided with connection holes, and the number of connection holes is six. The spark block bracket 14 and the spark baffle 15 form a flange connection, and the upper end of the spark baffle 15 is a transparent acrylic plate.

[0034] In some examples, when grinding metal castings, the spark baffle 15 flange is first connected to the upper end of the spark block holder 14. The flange end of the spark baffle 15 is aligned with the upper end of the spark block holder 14, ensuring that the holes of both fit completely. The connection is fixed with screws to prevent loosening. The device is moved to the target position using the casters 2 at the bottom of the worktable 1, ensuring that the ground is flat. The vertical height of the worktable 1 is adjusted according to the size of the casting. The motor is started to drive the hydraulic rod 3. The hydraulic rod 3 slides through the groove 6, driving the support rod 7 to move. The gear 8 inside the support rod 7 meshes with the rack 5, driving the servo motor 10 to lift and lower, achieving precise height adjustment. A protective device 13 is installed on the outside of the sand tray 12 to prevent sparks or debris from flying during grinding. The metal casting is stably placed in the contact area of ​​the sand tray 12. The servo motor 10 is started to drive the rotating rod 11 to rotate the sand tray 12 at high speed. The metal casting is slowly moved to contact the sand tray 12, and even pressure is applied for grinding.

[0035] like Figure 4 As shown, a floor-standing metal casting grinding wheel machine is provided in another embodiment of the present invention. A base 16 is fixedly installed above the servo motor 10. A collection box 17 is fixedly installed at the upper end of the base 16. Filter plates 18 are fixedly connected to both sides inside the collection box 17. A collection plate 19 is fixedly installed inside the filter plates 18. A fan 20 is fixedly installed at the rear end of the collection box 17. Conveying pipes 21 are fixedly connected to both sides at the upper end of the collection box 17. An adsorption pipe 22 is fixedly installed on one side of the conveying pipe 21. An adsorption groove 23 is fixedly installed at the lower end of the adsorption pipe 22. A rotatable actuator 24 is rotatably connected to one side of the adsorption groove 23. A mounting bracket 25 is fixedly installed on the side end of the rotatable actuator 24.

[0036] For example, such as Figure 4 As shown, the bottom angle of the base 16 is in contact with the top angle of the servo motor 10. The filter plate 18 is symmetrically installed on the left and right sides of the collection plate 19 with the collection plate 19 as the center reference. The conveying pipe 21 is fixedly connected to the front and rear sides of the collection box 17 with the upper left side of the collection box 17 as the center reference.

[0037] For example, such as Figure 1 As shown, the adsorption tank 23 is rotatably connected to the mounting bracket 25 via the rotator 24. The interior of the rotator 24 consists of two meshing slots, and the rear end face of the mounting bracket 25 is in contact with the inner side of the protective cover.

[0038] In some examples, when using a grinding wheel to grind metal castings, the operator starts the blower 20 to extract air and dust near the sanding disc 12. The dusty air is then drawn into the adsorption tube 22 through the adsorption tank 23. The adsorption tube 22 is connected to the upper end of the collection box 17 through the conveying pipe 21, so that the dust and debris from the grinding are collected in the collection box 17. A filter plate 18 is installed in the collection box 17 to intercept large dust particles. When the dust enters the collection box 17, the gas is ionized by a high-voltage electric field to generate charged particles. These charged particles collide with the dust particles and charge them. The charged dust is then adsorbed onto the collection plate 19 under the action of the electric field force, thus achieving dust collection. A rotator 24 is installed on the side of the adsorption tank 23. The operator rotates the adsorption tank 23, and the angle of the adsorption tank 23 is adjusted by rotating the rotator 24.
