[0002] Nonferrous metals, in a narrow sense, are also called non-ferrous metals. They are a general term for all metals other than iron, manganese and chromium. Nonferrous alloys are alloys composed of a nonferrous metal as a matrix and one or more other elements. Nonferrous metals usually refer to all metals except iron and iron-based alloys. Nonferrous metal castings have more burrs on their surfaces and need to be polished to remove the burrs and achieve the designed surface finish requirements.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-3 shown, a surface treatment and polishing machine for non-ferrous metal castings includes a box body 1. At the upper end inside the box body 1, a hydraulic rod 2 is fixedly arranged, and the lower half of the hydraulic rod 2 does not contact the box body 1 and is arranged to be rotatable. In the middle of the lower end of the hydraulic rod 2, a limiting plate 3 is rotatably arranged. A sleeve 4 is slidably arranged around the hydraulic rod 2, and a limiting block 5 is slidably arranged inside the hydraulic rod 2. When replacing the grinding disc 6, all the limiting blocks 5 are pushed into the hydraulic rod 2, so that the sleeve 4 and the grinding disc 6 can be removed. During installation, the grinding disc 6 is directly aligned with the limiting plate 3 and inserted, and then the lower half of the hydraulic rod 2 is rotated. The limiting block 5 is thrown out by centrifugal force and enters the sleeve 4, so that it can be quickly fixed and will not shift during operation.

[0026] Furthermore, the lower half of the hydraulic rod 2 is rotatable but does not provide power for the limiting plate 3. The power of the limiting plate 3 comes from a built-in motor, which is convenient for workers to operate during disassembly.

[0027] As Figure 2 、 Figures 4-6As shown in the figure, there are four limit blocks 5 evenly distributed around the center of the hydraulic rod 2. The limit blocks 5 are simultaneously slidably connected to the sleeve 4, and a grinding disc 6 is fixedly arranged at the lower end of the sleeve 4. The upper end of the grinding disc 6 is simultaneously slidably connected to the limit plate 3. A telescopic rod 7 is arranged below the grinding disc 6, and two groups of telescopic rods 7 are symmetrically arranged along the center line of the box body 1, with two in each group. One end of the telescopic rod 7 is fixedly connected to the box body 1, and a clamping block 9 is fixedly arranged at the other end of the telescopic rod 7. A first spring 8 is fixedly arranged inside the telescopic rod 7, and one end of the first spring 8 is simultaneously fixedly connected to the clamping block 9. An air pipe 10 is arranged inside the clamping block 9, and a second spring 11 is fixedly arranged through the box body 1 in the middle of the air pipe 10. A sealing gasket 12 is fixedly arranged at the end of the second spring 11 away from the air pipe 10, and the sealing gasket 12 is simultaneously slidably connected to the clamping block 9. An installation frame 13 is arranged on one side of the box body 1, and a sieve frame 14 is slidably arranged inside the installation frame 13. A third spring 15 is fixedly arranged in the middle of one end of the installation frame 13, and two third springs 15 are symmetrically arranged along the center line of the installation frame 13. A bolt 16 is fixedly arranged at the other end of the third spring 15, and the bolt 16 is simultaneously slidably connected to the box body 1 and the installation frame 13. A support 17 is fixedly arranged at the lower end inside the box body 1, and the support 17 is in a cross shape. A fourth spring 18 is fixedly arranged at the upper end of the support 17, and a sealing plug 19 is fixedly arranged at the upper end of the fourth spring 18. The sealing plug 19 is simultaneously slidably connected to the box body 1 and the lower end of the sieve frame 14. When clamping a metal part, press down the sealing gasket 12. In this way, under the action of the first spring 8 and manual force, the clamping block 9 clamps on both sides of the metal part, and at the same time, external air is inhaled. When releasing the sealing gasket 12, the metal part is clamped under the dual action of the internal air and the first spring 8. In this way, the clamping effect can be ensured while the working efficiency is improved; when the sewage containing impurities enters the sieve frame 14, through the multi-stage screening of multiple sieve frames 14, impurities of different thicknesses and sizes can be classified for easy collection and treatment of the impurities. And when the installation frame 13 is located inside the box body 1, the sieve frame 14 can press down the sealing plug 19, and connecting an external water pipe to the bottom end of the device can collect the filtered sewage.

[0028] Furthermore, the cooperation of the third spring 15 and the bolt 16 can fix the installation frame 13 when it is located inside the device, preventing it from shifting during operation.

[0029] Working principle: When using this surface treatment and polishing machine for non-ferrous metal castings, first, when replacing the grinding disc 6, push all the limit blocks 5 into the interior of the hydraulic rod 2, so that the sleeve 4 and the grinding disc 6 can be removed. And during installation, directly align the grinding disc 6 with the limit plate 3 and insert it, then rotate the lower part of the hydraulic rod 2, and the limit blocks 5 will be thrown out by centrifugal force and enter the sleeve 4, so that it can be quickly fixed and will not shift during operation; secondly, when clamping the metal part, press the sealing gasket 12, so that under the action of the first spring 8 and manual force, the clamping blocks 9 clamp on both sides of the metal part, and at the same time, external air is inhaled. When the sealing gasket 12 is released, the metal part is clamped under the dual action of the internal air and the first spring 8, which can ensure the clamping effect and improve the working efficiency at the same time; finally, when the sewage containing impurities enters the sieve frame 14, through the multi-stage screening of multiple sieve frames 14, impurities of different thicknesses and sizes can be classified for easy collection and treatment of the impurities. And when the installation frame 13 is located inside the box body 1, the sieve frame 14 can press down the sealing plug 19, and connect the external water pipe to the bottom end of the device to collect the filtered sewage. This is the working principle of this surface treatment and polishing machine for non-ferrous metal castings.
