[0002] In the industrial manufacturing sector, especially in metal product processing, surface treatment, and fine chemical industries such as coatings and inks, sand milling is of paramount importance. Its main purpose is to finely grind various raw materials or semi-finished products to obtain specific particle size distribution, uniform surface quality, and ideal physicochemical properties, thereby meeting the stringent requirements of subsequent production processes or the final performance of the product. Sand mills are typically used for grinding.

[0003] Chinese Utility Model Patent Publication No. CN214514964U discloses a small sand mill. This small sand mill can move the lifting column up and down by meshing a first bevel gear and a second bevel gear and meshing a transmission rotating shaft with a lifting column. This rotation of the rotating shaft can drive the motor to move up and down. A locking rod is provided on the side of the support column to lock the lifting column again, preventing relative movement during the operation of the sand mill from affecting the sample preparation. However, in this small sand mill, the grinding cylinder is fixedly installed on the base plate, making it inconvenient to disassemble and maintain. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a stainless steel CNC sand mill, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a stainless steel CNC sand mill, including a base plate, a support foot fixedly connected to the lower end of the base plate, a column fixedly connected to the upper end of the base plate, a crossbar fixedly connected to the outer side of the column, an electrical box fixedly connected to the upper end of the crossbar, a ring seat sleeved to the outer side of the column, a motor fixedly connected to the front end of the ring seat, a self-tightening head fixedly connected to the output end of the motor, a gasket provided on the upper end of the base plate, a sand mill cylinder provided on the upper end of the gasket, a handle provided on the front end of the sand mill cylinder, a cover plate provided on the upper end of the sand mill cylinder, a sand mill head snapped to the lower end of the self-tightening head, a clamping assembly fixedly connected to the upper end of the base plate, and the electrical box and the motor being electrically connected;

[0006] The clamp assembly includes a support column, a sliding rod, a clamp, a groove, and a locking bolt. The sliding rod is provided on the outside of the support column, and a clamp is fixedly connected to one end of the sliding rod near the grinding cylinder. The clamp has grooves at both ends, and a locking bolt is provided at the upper end of the support column.

[0007] Preferably, the ring seat and the column are slidably connected, and the ring seat and the column are locked and fixed by locking bolts. Both the grinding cylinder and the grinding head are made of 316 stainless steel.

[0008] The above technical solution incorporates a ring base, allowing for adjustment of the motor's orientation.

[0009] Preferably, the gasket is made of polytetrafluoroethylene material, and a silicone rubber pad is bonded to the bottom of the support leg.

[0010] Through the above technical solution, the gasket is made of polytetrafluoroethylene material, which is relatively wear-resistant, and the silicone rubber pad at the bottom of the support foot has good anti-slip and shock absorption properties, preventing the sand mill from shifting due to vibration or external force during operation, ensuring operational safety, absorbing and buffering the vibration generated during equipment operation, and reducing noise.

[0011] Preferably, there are two identical clamping assemblies that are symmetrically arranged, and the two clamping assemblies are axially symmetrical about the center line of the short side of the base plate.

[0012] Through the above technical solution, two symmetrically distributed clamping assemblies apply uniform and stable clamping force from both sides of the sand mill cylinder, ensuring that the sand mill cylinder can always be kept in the accurate position during operation, thereby ensuring the stability of the sand milling process and improving the overall rigidity and reliability of the sand mill.

[0013] Preferably, there are two identical symmetrical cover plates, and the cover plates are fastened to the grinding cylinder.

[0014] With the above technical solution, the two cover plates fully cover the upper opening of the grinding cylinder, effectively preventing the splashing of materials and glass beads during the grinding process. The fastening connection of the cover plates is simple and convenient, allowing operators to quickly disassemble and install the cover plates when adding materials, cleaning the grinding cylinder, or replacing the grinding head, thereby improving the ease of operation and maintenance efficiency of the equipment.

[0015] Preferably, the clamp has an arc-shaped structure, the clamp is adapted to the outer wall of the grinding cylinder, and the groove is adapted to the handle.

[0016] Through the above technical solution, the arc-shaped clamp can closely fit the outer wall shape of the grinding cylinder, achieving the maximum contact area, thereby providing a more reliable and stable clamping effect. In use, place the material and glass beads into the grinding cylinder, then insert the grinding head into the grinding cylinder, and place the grinding cylinder in the center of the two clamping assemblies. Generally, the left clamping assembly is fixed in place. Place the grinding cylinder tightly against the left clamping assembly, and install the grinding head into the self-tightening clamp. A positioning plate is provided at the upper end of the grinding head, and the positioning plate contacts the grinding head. Twist the clamp with both hands. Tighten the self-tightening head to lock and fix the grinding head. Lift the grinding cylinder and insert the shim into the lower end of the grinding cylinder. Adjust the clamp assembly on the right side and slide the adjustment rod on the support until the clamp clamps the grinding cylinder. Turn the locking bolt to lock the rod. At this time, the two clamps press the grinding cylinder tightly, and the handle is located in the groove, which is firmly fixed. Grinding can be performed. The groove is the handle limit, and the grinding cylinder will not rotate or move during grinding. After grinding, first loosen the self-tightening head with both hands, then remove the clamp assembly on the right side and remove the shim to take out the grinding cylinder.

[0017] Preferably, the locking bolt is threaded to the support column, and the slide rod is slidably connected to the support column.

[0018] With the above technical solution, the clamp assembly can be used to lock the sliding rod by adjusting its position and then tightening it with locking bolts, making the operation simple.

[0020] Beneficial effects:

[0021] 1. This stainless steel CNC sander features two clamping assemblies symmetrically distributed around the centerline of the short side of the base plate. These assemblies apply uniform and stable clamping force from both sides of the sanding cylinder, ensuring the cylinder remains precisely positioned throughout the sanding process. This effectively prevents uneven sanding caused by cylinder misalignment. To adjust the clamps, slide the adjusting rod on the support until the clamps secure the sanding cylinder. Then, rotate the locking bolt to lock the rod. At this point, the two clamps press the sanding cylinder firmly, and the handle is securely fixed in the groove, allowing for sanding. The groove also limits the handle's position, preventing the sanding cylinder from rotating or shifting during sanding. The sander has a simple structure, low manufacturing cost, and is easy to promote. The sanding cylinder is easy to disassemble and maintain, making it convenient to use.

[0022] 2. The stainless steel CNC sander uses polytetrafluoroethylene (PTFE) for its gaskets, which are highly wear-resistant. The silicone rubber pads at the bottom of the support feet have excellent anti-slip and shock-absorbing properties, preventing the sander from shifting due to vibration or external forces during operation, ensuring operational safety, and absorbing and buffering vibrations generated during equipment operation to reduce noise.
