Description

Technical Field

[0001] The utility model relates to the technical field of quartz grinding, in particular to a double-sided grinding structure for special-shaped quartz pieces. Background Art

[0002] Quartz is a mineral resource with very stable physical and chemical properties. Its crystals belong to trigonal oxide minerals. Quartz block, also known as silica, is mainly used as raw material for producing quartz sand (also known as silica sand), as well as raw material for quartz refractory materials and sintering ferrosilicon. In the process of quartz processing, double-sided grinding device is required to achieve double-sided grinding treatment and obtain fine products.

[0003] The existing Chinese utility model patent with reference announcement number CN212145704U discloses a double-sided grinding device for quartz products, including a support frame and a five-point bolt, a workbench is installed on the top of the support frame, two hydraulic cylinders and a mounting frame are installed on the top of the workbench, a lower drive motor is installed on the side of the mounting frame, the output end of the lower drive motor is connected to the lower grinding roller shaft, the tops of the two telescopic columns are connected to a positioning seat, the tops of the two positioning seats are respectively connected to a motor seat and a bearing seat, an upper drive motor is installed on the side of the motor seat, the output end of the upper drive motor is connected to a rotating spindle, one end of the rotating spindle is connected to an upper grinding roller shaft, and one end of the upper grinding roller shaft is connected to the bearing seat. In the utility model, two hydraulic cylinders can drive the upper grinding roller shaft to move up and down, so that the distance between the upper grinding roller shaft and the lower grinding roller shaft can be adjusted, and then different types of quartz products and grinding thickness can be polished, and the applicability is strong.

[0004] Generally, quartz is polished by a grinding wheel. During the polishing process, the quartz parts need to be fixed. When fixing the quartz parts with different surfaces, a relatively stable contact surface cannot be formed between the limiting structure and the quartz parts, which causes the quartz parts with different surfaces to move during the polishing process and affects the polishing effect. At the same time, during the double-sided polishing process, the two sides of the quartz parts cannot maintain the same pressure with the grinding wheels on the upper and lower sides, which causes the polishing effect between the upper and lower surfaces of the quartz parts to be inconsistent.

[0015] Compared with the prior art, the utility model provides a double-sided polishing structure for special-shaped quartz pieces, which has the following beneficial effects:

[0016] 1. The utility model sets a rubber block, which is fixedly installed at the front end of a group of limit blocks. The rubber block is a rectangular tubular structure, and the inner wall of the rubber block is symmetrically provided with a rectangular structure connecting the front and rear side walls with the center of the rubber block as the reference. This structure makes the central part of the side walls of the rubber block more likely to deform. When the center is stressed, the rubber block will generate an angle with the stress point as the vertex. The limit block is rotatably connected with the adapter block through the connecting shaft, and the adapter block is fixedly installed at the movable end of the limit piston. The two sides of the limit piston are The root is a group of "X"-shaped parts installed at the four corners of the limit frame. When fixing, the quartz piece needs to be located inside the limit frame. Then the limit piston is extended to drive the rubber block to move so that the rubber block contacts the quartz piece. The rubber block will deform under the pressure applied by the limit piston, thereby fitting the outer edge of the quartz piece. At the same time, the limit block will rotate under the drive of the rubber block, so that the rubber block can form more contact surfaces between the quartz piece to facilitate the fixing of the eccentric quartz pieces, so as to avoid changes in the position of the eccentric quartz pieces during the grinding process.

[0017] 2. The utility model sets a support spring, which is installed on the outside of the limit column and has an upper end in contact with the bottom surface of the limit frame. A sliding connection is formed between the limit frame and the limit column. After the quartz stone with different faces is fixed inside the limit frame, the relative position between the movable plate and the limit plate is adjusted by pressing down the piston. After the upper grinding wheel contacts the upper working surface of the quartz piece, it will drive the limit frame to move downward so that the limit frame squeezes the support spring until the lower working surface of the quartz piece contacts the lower grinding wheel. The pressure generated by the downward piston on the quartz piece will be transmitted to the lower grinding wheel. In this way, the relative pressure between the upper and lower working surfaces of the quartz piece and the upper and lower grinding wheels can be kept consistent during the grinding process, so as to avoid a large difference in the grinding effects of the upper and lower working surfaces of the quartz piece.
