Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a precision cutting device. Background Art

[0002] Glass is made from quartz sand, soda ash, feldspar, and limestone at high temperatures. The melt gradually increases in viscosity during cooling, resulting in a non-crystallized solid material that is brittle and transparent. There are quartz glass, silicate glass, soda-lime glass, fluoride glass, high-temperature glass, high-pressure-resistant glass, UV-resistant glass, and explosion-proof glass. It usually refers to silicate glass, which is made from quartz sand, soda ash, feldspar, and limestone. After mixing, high-temperature melting, and homogenization, it is formed and then annealed. It is widely used in construction, daily necessities, medicine, chemistry, electronics, instrumentation, and nuclear engineering. Existing glass cutting uses glass cutters or large glass cutting equipment. Large glass cutting equipment is expensive, inconvenient to operate, and difficult to carry. Glass cutters cannot cut round glass. The "circular glass cutting device" disclosed in the application number "CN201810761063.7" solves the problem of using glass knives or large glass cutting equipment for existing glass cutting through specific technical structure settings. Large glass cutting equipment is expensive, inconvenient to operate, and inconvenient to carry, and circular glass cannot be cut when using glass knives. However, there are still many defects in actual use, such as: it uses a motor-driven connection adjustment device to make the cutting knife rotate in a circle, but when the cutting knife is attached to the glass surface and rotates, it will encounter resistance from the glass surface, which will cause the knife rod to become unstable when rotating in a circle, resulting in insufficient roundness of the cut glass and skewness, etc., which will lead to the scrapping of the glass cutting. Utility Model Content

[0003] The purpose of the present invention is to provide a precision cutting device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision cutting equipment, comprising a base, a flat plate, a second screw and a cross bar, an electric push rod fixed in the middle of the inner part of the base, the output end of the electric push rod is connected to the flat plate, and the flat plate is arranged in the middle of the outer top surface of the base, the top surface of the flat plate is rotatably connected to a bracket at both ends, a first screw sleeve is installed through the middle of the top end of the bracket, a first screw is inserted into the inside of the first screw sleeve, a frame is fixed at both ends of the outer top surface of the base, a motor is installed through the middle of the top end of the frame, and the output end of the motor is connected to the cross bar.

[0005] When using a precision cutting device in the present technical solution, the staff must first connect the external power supply to the utility model and control the operation of the utility model through the control panel. The staff places the glass to be cut into a circle on the surface of the flat plate. After placing it, the staff rotates the bracket to move the pressure plate onto the glass. After rotating and moving, the staff holds the first handle and applies a rotational force. The rotational force applied to the first handle will be synchronized to the first screw. The first screw rotates inside the first screw sleeve. The engagement of the thread will cause the first screw to move inside the first screw sleeve. The moving first screw will push the pressure plate connected to the bottom end to descend. The descending pressure plate presses and fixes the glass. After the glass is pressed and fixed, the staff adjusts it according to the size of the circular glass to be cut. To adjust the distance between the two cutting knives, the staff holds the second turning handle and applies a rotational force, and the rotational force applied to the second turning handle will be synchronized to the second screw. After the second screw rotates, the second screw sleeves on both end surfaces will move toward or away from each other due to the engagement of the threads, and the two second screw sleeves moving toward or away from each other will move together with the knife rods connected to the outer surfaces, and after the two knife rods move, they will move together with the cutting knives fixed at the bottom. After the distance between the two cutting knives is adjusted, the staff controls the electric push rod to lift the flat plate, so that the glass is attached to the surface of the cutting knives. After it is attached, the staff starts the motor, and the motor rotates the cross bar connected to the output end. After the cross bar rotates, the two cutting knives will perform circle cutting operations on the surface of the glass.

[0006] Preferably, a second screw is rotatably mounted inside the crossbar, and a second handle is fixed to one end of the second screw. The installation of the second handle makes it convenient for staff to apply rotational force to the second screw, providing a force application point.

[0007] Preferably, the second screw rod is provided with a second screw sleeve at each end, the outer surface of the second screw sleeve being connected to a cutter bar, and a scratching knife being fixed to the bottom end of the cutter bar. The cooperation between the second screw rod and the second screw sleeve allows the cutter bar to move due to the threaded engagement, thereby indirectly controlling the position of the scratching knife. By providing the scratching knife, the glass can be cut, achieving a precise cutting effect.

[0008] Preferably, a groove is formed at the outer bottom end of the crossbar, and a knife rod slides inside the groove. The groove allows the knife rod to be limited and move inside the groove, thereby preventing the knife rod from rotating with the second screw sleeve.

[0009] Preferably, a first handle is fixed to the top of the first screw, and a buffer pad is rotatably connected to the bottom of the first handle. A pressure plate is fixed to the bottom surface of the buffer pad. The installation of the first handle makes it convenient for workers to apply rotational force to the first screw, providing a force application point. Through the cooperation of the buffer pad and the pressure plate, the glass placed on the flat surface can be pressed and fixed, achieving the effect of buffering and pressing to prevent damage to the glass.

[0010] Preferably, telescopic rods are fixed at both ends of the interior of the base, and the top ends of the telescopic rods are connected to the flat plate. The telescopic rods are composed of an inner rod retracted into a sleeve rod. The installation of the telescopic rods allows the electric push rod to stabilize the two ends of the bottom surface of the flat plate when it is raised and lowered, achieving a stable lifting and moving effect of the flat plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model uses a motor to drive a cross bar, and a second screw and a second screw sleeve are provided inside the cross bar. The distance between the two scoring knives is indirectly controlled by thread engagement, so that the staff can adjust according to the requirements of the cutting size. There are two scoring knives, which can be driven by a rotating cross bar. In this way, the two scoring knives are used to cut the glass surface, which improves the stability and avoids the occurrence of crooked cutting. BRIEF DESCRIPTION OF THE DRAWINGS
