Description

Technical Field

[0001] The utility model relates to the field of numerical control mechanical brake structures, in particular to a vertical motion balancing and braking integrated device. Background Art

[0002] A vertical motion balancing and braking device is a support device used to protect the brakes of CNC machinery. It is primarily used to protect the spindles of linear motor-driven grinding and precision machining equipment. It creates a safe distance between the workpiece and the workpiece during an abnormal stop, protecting grinding wheels or milling tools. With the continuous advancement of technology, the manufacturing requirements for vertical motion balancing and braking devices are becoming increasingly stringent.

[0003] The existing CNC mechanical brake device has certain disadvantages when used. First, the existing CNC mechanical brake device cannot be controlled conveniently and quickly, and cannot protect the grinding wheel or milling tool in the CNC machine well, which is not conducive to people's use. In addition, the existing CNC mechanical brake device does not have an automatic retraction protection device, which is unsafe and has certain adverse effects on the actual use process. For this reason, we propose a vertical motion balancing and braking integrated device. Utility Model Content

[0004] Technical problem solved: In response to the shortcomings of the existing technology, the utility model provides an integrated vertical motion balancing and braking device, which is mainly used for spindle processing protection of grinding equipment or precision processing equipment driven by a linear motor. In application, it can create a safe distance between the processing object and the workpiece when the equipment stops abnormally, protect the grinding wheel or milling tool, and can effectively solve the problems in the background technology.

[0005] The cam is pressurized and has a pressure relief valve which is pressurized inside the cam and has a pressure relief valve which is pressurized inside the cam.

[0006] Preferably, after the equipment is turned on, the vertical slide rail does not move and the air intake locking valve is in a closed state.

[0007] Preferably, after the equipment is prepared, the motor of the vertical slide rail is powered on, the intake locking valve is opened, and the exhaust locking valve is opened.

[0008] Preferably, the constant pressure air storage tank is connected to the counterweight brake cylinder via an air intake pipe, and the air pressure between the constant pressure air storage tank and the counterweight brake cylinder is kept consistent.

[0009] Preferably, when the counterweight brake cylinder is in counterweight action, the brake function is invalid, the piston rod is connected to the vertical motion slide, and the weight of the vertical motion slide is lifted by the counterweight brake cylinder due to the air pressure on the lower side of the cylinder piston, and will not generate a downward force on the motor. When the vertical motion slide moves downward, the compressed air in the high-pressure cavity is driven back to the constant-pressure gas storage tank. When the vertical motion slide moves upward, the cylinder piston rises, and the air pressure in the high-pressure cavity drops, which will be supplemented by the gas in the constant-pressure gas storage tank to ensure the constancy of the air pressure in the high-pressure cavity. The air pressure on the upper side of the cylinder piston is discharged through the exhaust locking valve, thereby keeping the driving force of the vertical motor constant.

[0010] Preferably, when the counterweight brake cylinder is used for braking, after the equipment is powered on and ready for preparation, it starts to make a brake safety reserve, the intake locking valve is locked, the exhaust locking valve is opened, the vertical slide rail moves slightly downward, and the air pressure in the high-pressure cavity begins to increase. After meeting the requirements of the high-pressure valve, air is stored in the high-pressure air supply valve cavity. After the end, the intake locking valve is opened and the high-pressure energy storage is completed. In an emergency, the intake locking valve loses power, the exhaust locking valve loses power, the intake locking valve and the exhaust locking valve are locked, and the high-pressure valve is opened. The air pressure in the high-pressure cavity is higher than the upper cavity of the counterweight brake cylinder, the cylinder piston is lifted upward, and the vertical motion slide is lifted at the same time. When the lifting moves to the point where the air pressure on the upper and lower sides of the cylinder piston is equal, the movement stops.

[0011] Beneficial effects: Compared with the prior art, the present invention provides a vertical motion balancing and braking integrated device with the following beneficial effects: This vertical motion balancing and braking integrated device is mainly used for spindle processing protection of grinding equipment or precision machining equipment driven by a linear motor. In application, it can create a safe distance between the workpiece and the workpiece when the equipment stops abnormally, protecting the grinding wheel or milling tool. After the equipment is turned on, the vertical axis does not move and the air intake valve is closed. After the equipment is prepared, the vertical axis motor is powered on, the air intake valve opens, the air exhaust valve opens, the counterweight cylinder is connected to the constant pressure air tank, and the air pressure of the two is consistent. At this time, the cylinder acts as a counterweight. (The brake function is invalid) The cylinder piston rod is connected to the vertical slide. The weight of the vertical slide is lifted by the cylinder due to the air pressure on the bottom side of the piston, and will not generate a downward force on the motor. When the slide moves downward, the compressed air in the chamber under the piston is driven back to the air tank. When the slide moves upward, the piston rises and the air pressure in the chamber under the piston drops, which will be replenished by the gas in the air tank. Maintain constant pressure in the chamber below the piston. Air pressure above the piston is exhausted through the exhaust valve, thereby maintaining constant driving force for the vertical motor. When the cylinder is used as a brake: After power-on and equipment preparation, a braking safety reserve begins. The intake valve locks, the exhaust valve opens, and the vertical axis moves slightly downward. Air pressure in the cylinder's lower chamber begins to increase, reaching the pressure required by the high-pressure valve, which then stores air in the high-pressure protection valve chamber. After this pressure is reached, the intake valve opens, and high-pressure energy storage ends. In an emergency (power outage or motor failure), the intake and exhaust valves lose power, locking the intake and exhaust valves and simultaneously opening the high-pressure valve. The air pressure in the chamber below the piston becomes higher than that above it, causing the piston to lift upward, and the slide to lift simultaneously. Movement stops when the pressures above and below the piston are equal. This integrated vertical motion balancing and braking device features a simple structure and easy operation, offering superior performance compared to traditional methods.

[0019] like Figure 1-3As shown, a vertical motion balancing and braking integrated device includes a constant pressure air tank 1, a vertical slide rail 4 and a counterweight brake cylinder 8. A pressure relief device 2 is positioned at the bottom of the constant pressure air tank 1, a vertical motion slide 5 is movably provided on the vertical slide rail 4, a cylinder piston 11 is provided inside the counterweight brake cylinder 8, an air intake locking valve 7 is installed on one side of the bottom of the counterweight brake cylinder 8, a high-pressure cavity 6 is installed on the other side of the bottom of the counterweight brake cylinder 8, a high-pressure air replenishing valve 12 and a high-pressure valve 13 are provided between the counterweight brake cylinder 8 and the high-pressure cavity 6, and the counterweight brake cylinder 8 is provided with a high-pressure air supply valve 12 and a high-pressure valve 13. An exhaust lock valve 10 is installed on the top side of 8, and an air inlet 9 is provided on the exhaust lock valve 10. A vertical motion slide 5 is movably provided on the inner side of the vertical slide rail 4. A piston rod 14 is connected between the vertical motion slide 5 and the cylinder piston 11, and an air intake pipe 3 is connected between the air intake lock valve 7 and the constant pressure air tank 1. It is mainly used for spindle processing protection of grinding equipment or precision processing equipment driven by a linear motor. In application, a safe distance can be created between the processing object and the workpiece when the equipment is abnormally stopped, thereby protecting the grinding wheel or milling tool.

[0020] Furthermore, after the equipment is turned on, the vertical slide rail 4 does not move and the air intake lock valve 7 is in a closed state.

[0021] Furthermore, after the equipment is prepared, the motor of the vertical slide rail 4 is powered on, the intake lock valve 7 is opened, and the exhaust lock valve 10 is opened.

[0022] Furthermore, the constant pressure air storage tank 1 and the counterweight brake cylinder 8 are connected through the air intake pipe 3, and the air pressure between the constant pressure air storage tank 1 and the counterweight brake cylinder 8 is kept consistent.

[0023] Furthermore, when the counterweight brake cylinder 8 is in counterweight action, the brake function is invalid, and the piston rod 14 is connected to the vertical motion slide 5. The weight of the vertical motion slide 5 is lifted by the counterweight brake cylinder 8 due to the air pressure on the lower side of the cylinder piston 11, and no downward force is generated on the motor. When the vertical motion slide 5 moves downward, the compressed air in the high-pressure cavity 6 is driven back to the constant-pressure gas storage tank 1. When the vertical motion slide 5 moves upward, the cylinder piston 11 rises, and the air pressure in the high-pressure cavity 6 drops, which will be supplemented by the gas in the constant-pressure gas storage tank 1 to ensure the constancy of the air pressure in the high-pressure cavity 6. The air pressure on the upper side of the cylinder piston 11 is discharged through the exhaust locking valve 10, thereby keeping the driving force of the vertical motor constant.

[0024] Furthermore, when the counterweight brake cylinder 8 is used for braking, after the equipment is powered on and ready for preparation, it starts to make a brake safety reserve, the intake locking valve 7 is locked, the exhaust locking valve 10 is opened, the vertical slide rail 4 moves slightly downward, and the air pressure in the high-pressure chamber 6 begins to increase. After reaching the requirements of the high-pressure valve 13, air is stored in the high-pressure air supply valve 12 cavity. After the end, the intake locking valve 7 is opened, and the high-pressure energy storage is completed. In an emergency, the intake locking valve 7 loses power, the exhaust locking valve 10 loses power, the intake locking valve 7 and the exhaust locking valve 10 are locked, and the high-pressure valve 13 opens. The air pressure in the high-pressure chamber 6 is higher than the upper cavity of the counterweight brake cylinder 8, the cylinder piston 11 is lifted upward, and the vertical motion slide 5 is lifted at the same time. When the lifting moves to the point where the air pressure on the upper and lower sides of the cylinder piston 11 is equal, the movement stops.

[0025] Working principle: The utility model includes a constant pressure gas storage tank 1, a pressure relief device 2, an air intake pipe 3, a vertical slide rail 4, a vertical motion slide 5, a high-pressure cavity 6, an air intake locking valve 7, a counterweight brake cylinder 8, an air inlet 9, an exhaust locking valve 10, a cylinder piston 11, a high-pressure air supply valve 12, a high-pressure valve 13, and a piston rod 14. After the equipment is turned on, the vertical axis does not move, and the air intake valve is in a closed state. After the equipment is prepared, the vertical axis motor is powered on, the air intake valve is opened, the exhaust valve is opened, the counterweight cylinder is connected to the constant pressure gas storage tank, and the air pressure of the two is kept consistent. At this time, the cylinder acts as a counterweight. (The brake function is invalid) The cylinder piston rod is connected to the vertical slide, and the weight of the vertical slide is lifted by the cylinder due to the air pressure on the lower side of the piston, and will not generate a downward force on the motor. When the slide moves downward, compressed air in the chamber below the piston is driven back into the air reservoir. When the slide moves upward, the piston rises, causing the pressure in the chamber below to drop and be replenished by air from the air reservoir. This maintains constant pressure in the chamber below the piston. Pressure above the piston is discharged through the exhaust valve, maintaining constant driving force for the vertical motor. When the cylinder is used as a brake: After power-on and equipment preparation, a braking safety reserve begins. The intake valve locks, the exhaust valve opens, and the vertical axis moves slightly downward. The pressure in the chamber below the cylinder begins to increase. Once it reaches the pressure required by the high-pressure valve, air is stored in the high-pressure protection valve chamber. After this, the intake valve opens, terminating high-pressure energy storage. In an emergency (power outage or motor failure), the intake and exhaust valves lose power, locking the intake and exhaust valves and simultaneously opening the high-pressure valve. Pressure in the chamber below the piston becomes higher than pressure in the chamber above it, causing the piston to rise, raising the slide simultaneously. When the lifting movement reaches the point where the air pressure on both sides of the piston is equal, the movement stops. This is mainly used for spindle protection of grinding equipment or precision machining equipment driven by linear motors. In application, it can create a safe distance between the workpiece and the workpiece when the equipment stops abnormally, thus protecting the grinding wheel or milling tool.
