Description

Technical Field

[0001] The utility model relates to the technical field of crystal production equipment, in particular to a crystal grinding machine with a lifting upper bracket. Background Art

[0002] A crystal grinder is a device that uses abrasives and grinding tools to process hard and brittle materials such as crystal and gemstones. Depending on the grinding method, crystal grinders can be divided into many types, such as vibration grinders, drum grinders, surface grinders, etc. Its working principle is mainly to remove uneven parts of the material surface through the friction and cutting effect between the abrasive and the crystal material to achieve the purpose of grinding and polishing. During the grinding process, factors such as the choice of abrasives and grinding tools, grinding pressure and rotation speed will affect the grinding effect.

[0003] The traditional grinding feed method of a crystal grinding machine is: the spindle drives the grinding disc to rotate, and the grinding disc is driven by a lifting device located below the spindle assembly to make an up and down reciprocating motion. However, this grinding feed method has the following disadvantages: Since the spindle is lifted up and down, when the spindle rises, there is a gap between the inner and outer spindle guide sleeves. When the grinding disc is subjected to force on one side during grinding, the grinding disc will tilt, thereby affecting the grinding quality of the crystal. Utility Model Content

[0006] Preferably, two lifting frames and two vertical pushing components are provided on the same longitudinal movable frame, and the two lifting frames and the two vertical pushing components are symmetrically arranged, so that the crystals on the corresponding two aluminum rows can be polished back and forth by moving the longitudinal pushing components.

[0007] Preferably, part of the top surface of the grinding platform is designed to be inclined so that the grinding waste can slide off and be removed automatically.

[0008] Preferably, the grinding platform and the longitudinal movable frame are both provided with linear slide rails, and the longitudinal movable frame and the lifting frame are both provided with sliding parts matching the linear slide rails, so as to improve the movement accuracy of the longitudinal movable frame and the lifting frame.

[0009] Preferably, when the crystal is ground, the rotating shaft assembly does not move up and down, and is fixedly connected to the frame, thereby ensuring that the grinding disc is not easily tilted when it is subjected to force when grinding the crystal.

[0010] Preferably, the aluminum bar is provided with left and right connecting shafts, which are rotatably connected to the lifting frame, and one of the connecting shafts is connected to the output shaft of the rotating motor. When the crystal is ground, the crystal swings along the center line of the left and right connecting shafts driven by the rotating motor.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] The main shaft assembly used in the crystal grinding machine does not move up and down, but is fixedly connected to the frame. The aluminum row used to set the crystal moves up and down with the lifting frame. This ensures the smooth rotation of the main shaft assembly and the grinding disc is not easy to tilt when grinding, thereby ensuring the grinding accuracy of the crystal.

[0013] The crystal grinding machine uses a grinding disc with two lifting frames, two vertical push components and two aluminum bars to grind the crystal. The joint action of the longitudinal moving frame and the longitudinal push component can improve the crystal grinding efficiency, and the two lifting frames are equipped with corresponding vertical push components that can independently control the height of the aluminum bars, so that different types of crystals can be ground synchronously, improving the practicality of the grinder. By rotating the motor to drive the aluminum bars to swing, different surfaces of the crystal can be polished, improving the comprehensiveness and grinding efficiency of the crystal.
