Description
Technical Field
The utility model relates to the field of numerical control machine tools, in particular to a Y-axis band-type brake system.
Background
On a numerical control machine tool, self-locking cannot be realized due to the reversibility of the movement of the ball screw nut pair; the Y-axis (vertical direction) load of the horizontal machine tool is very large, and can reach about 2000 kg in general cases; for the safety operation of the machine tool, namely, the machine tool stops operating due to improper manual operation or sudden power-off of the system, the vertical shaft is adopted, the spindle box rotates under the action of gravity to cause the screw rod to slide downwards until the Y axis reaches the lower end limit, so that the effect is dangerous, especially when an operator adjusts the machine tool in the machine tool or maintains the machine tool, the machine tool is more dangerous, a braking device must be installed, otherwise, the damage of the machine tool or the scrapping of machined parts and even the casualties of personnel are likely to be caused, and therefore, the addition of a set of safe and reliable band-type brake system is necessary.
Disclosure of Invention
In order to solve the problems, the utility model provides a safe and reliable Y-axis band-type brake system.
The Y-axis band brake system comprises a stand column, a bearing seat, a bearing, a ball screw nut pair and a brake, wherein the bearing seat is arranged on the stand column, the bearing seat is provided with the bearing, the ball screw nut pair is arranged in the bearing, the ball screw nut pair is fixed on the bearing seat through the bearing, the brake is fixed on the stand column, and the brake and the ball screw nut pair are connected and synchronously rotate.
In the scheme, the brake further comprises a flat key, the brake is fixed on the upright post, and the brake is connected with the ball screw nut pair through the flat key to synchronously rotate.
The utility model has the advantages and beneficial effects that: the utility model provides a safe and reliable Y-axis band-type brake system. The Y-axis band-type brake system can realize that the Y-axis position is locked under the condition of power failure of a machine tool under the heavy load, and improves the safety of the machine tool. The internal band-type brake mechanism and the external balance system of the servo motor are canceled, the servo motor without band-type brake is driven by a synchronous belt, and an independent brake is additionally arranged.

Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1 to 4, the utility model relates to a Y-axis band-type brake system, which comprises a stand column 1, a bearing seat 2, a bearing 3, a ball screw nut pair 4 and a brake 5, wherein the stand column 1 is a mounting base, the bearing seat 2 is arranged on the stand column 1, the bearing 3 is arranged on the bearing seat 2, the ball screw nut pair 4 is arranged in the bearing 3, the ball screw nut pair 4 is fixed on the bearing seat 2 through the bearing 3, the brake 5 is fixed on the stand column 1, and the brake 5 and the ball screw nut pair 4 are connected and synchronously rotate.
The brake 5 is fixed on the upright post 1 and is connected with the ball screw nut pair 4 through the flat key 6 to synchronously rotate.
Upright 1: the fixed supporting function of the foundation is realized in the whole band-type brake system;
bearing pedestal 2: a support bearing and a ball screw nut pair;
bearing 3: the support and the guide function are realized, meanwhile, the friction resistance is reduced, and the abrasion is reduced;
ball screw nut pair 4: converting the rotary motion into linear motion, and converting the driving force of the motor into lifting force of the Y-axis load;
a brake 5: friction torque is generated, the gravity of the Y-axis load is eliminated, and locking and sliding prevention are realized;
flat key 6: the torque is transmitted while preventing relative rotation between the mating members.
After the machine tool is electrified, the Y-axis servo motor is electrified to generate electromagnetic holding torque, and after the holding torque balances the self-gravity generated by the load through the ball screw nut pair, the brake is electrified to eliminate friction torque and lose braking effect, so that the machine tool can normally run. When the sudden machine tool stops running due to improper manual operation or sudden power failure of the system, the brake is powered off at the moment, the internal electromagnet power-off mechanical braking structure is reset, the clutch plate and the brake pad are rapidly attached to generate friction torque to brake, the friction torque balances self-gravity generated by load loss through the ball screw nut pair, the braking effect is realized, and adverse effects caused by sudden conditions (power failure of the Y-axis servo motor and no electromagnetic torque generation) are avoided.
The Y-axis band-type brake system can realize that the Y-axis position is locked under the condition of power failure of a machine tool under the heavy load, and improves the safety of the machine tool. The internal band-type brake mechanism and the external balance system of the servo motor are canceled, the servo motor without band-type brake is driven by a synchronous belt, and an independent brake is additionally arranged.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
