Description

Technical Field

[0001] The utility model relates to a three-hole blade fixing structure for a grinding machine. Background Art

[0002] Grinding machines are mainly used in the field of machining for grinding products or objects. Different grinding accuracy and structure are required for the objects, which leads to different requirements for the grinding accuracy and structure of the grinding machines. Therefore, grinding machines of different specifications, styles and functions are developed.

[0003] Three-hole blades are also common in daily life. For example, the blades on ordinary razors are three-hole blades. Such blades are generally thin, so the grinding of the cutting edges on both sides requires very high stability and precision of the grinder. Therefore, our company has designed a grinder specifically for grinding three-hole blades. However, the use of the grinder requires a special blade fixing mechanism to complete the fixation of the three-hole blade, while also meeting the requirements of the grinder. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a three-hole blade fixing structure for a grinder that can meet the needs of a grinder and complete the clamping of a three-hole blade. The blade has good stability after clamping, which is conducive to the subsequent grinding and cutting of the blade. The three-hole blade fixing structure for a grinder is practical and widely used.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A three-hole blade fixing structure for a grinding machine includes a fixing structure main body, which includes a support plate, a cylinder mounting plate, a pad, a bracket, a pressure block and a cylinder. The cylinder mounting plate is installed on the support plate, and the pad and cylinder are installed on the cylinder mounting plate. The bracket is installed on the pad, and the pressure block is arranged at the upper end of the bracket. An output shaft is provided on the cylinder, and the upper end of the output shaft passes through the bracket and is connected to the pressure block. The cylinder drives the pressure block to move up and down through the output shaft; a plurality of positioning holes are provided on the bracket, and positioning pins and springs are installed in the positioning holes, and the spring is arranged at the bottom of the positioning pin.

[0007] The utility model completes the clamping and fixing operation of the three-hole blade through the cooperation of the positioning pin, the cylinder, the output shaft, the bracket and the pressure block; realizes the simultaneous fixation of multiple three-hole blades, facilitates the subsequent continuous grinding operation of the three blades, and is convenient for clamping and has good stability, which is conducive to improving the grinding accuracy of the three-hole blades.

[0008] Preferably, a wire groove is provided on the upper surface of the bracket.

[0009] This setting facilitates the dissipation of heat during the grinding process of the three-hole blade through the effect of the wire groove, while reducing the adsorption force between the three-hole blade and the bracket, thereby facilitating the blanking operation after the three-hole blade is ground.

[0010] Preferably, a limiting groove is provided at the bottom of the pressing block, a pressure strip is installed in the limiting groove, and the pressure strip is a cylindrical structure.

[0011] This setting completes the compaction operation of the three-hole blade through the action of the pressure strip, which facilitates better completion of the fixing operation of the three-hole blade; the design of the cylindrical structure reduces the resistance during the movement of the pressure block and the pressure strip, and increases the convenience during the movement.

[0012] Preferably, the upper end of the positioning pin is a tapered structure.

[0013] This arrangement facilitates the placement of the three-hole blade through the effect of the tapered structure and facilitates locking the position of the three-hole blade when placed.

[0014] Preferably, a guide block is installed at the bottom of the support plate.

[0015] This arrangement limits the moving direction of the fixed structure body through the action of the guide block, so that it always maintains linear motion.

[0016] The beneficial effects of the utility model are: it can meet the use of the grinding machine, can complete the clamping of the three-hole blade, the blade has good stability after clamping, is conducive to the subsequent grinding and blanking of the blade, and is practical and widely used.
