Description

Technical Field

[0001] This utility model relates to the field of spindle technology for valve bevel grinding machines, specifically an automatic balancing spindle device for valve bevel grinding machines. Background Technology

[0002] The spindle of a valve bevel grinding machine is the core component of the grinding machine. Its main function is to mount the grinding wheel or abrasive and drive it to rotate at high speed during the grinding process, thereby achieving precision machining of the valve bevel.

[0003] The spindle of a valve bevel grinding machine is a key component, used to support and drive the grinding wheel or abrasive to rotate at high speed. Its precision and rigidity directly affect the machining quality and dimensional accuracy of the valve bevel. The design and manufacture of the spindle must meet the requirements of high precision, high rigidity, and high speed to ensure the stability and machining effect of the machining process. The spindle is usually made of high-precision materials to ensure its rotational accuracy and rigidity. The spindle is usually equipped with high-precision bearings, such as angular contact ball bearings or hydrodynamic bearings, to support the high-speed rotation of the spindle.

[0004] Currently, balancing the spindle of valve bevel grinding machines is mostly done manually. Manual balancing relies on the operator's experience and skill level and is easily affected by human factors, such as improper operation or lack of concentration, resulting in low balancing accuracy. Manual balancing is difficult to achieve high-precision measurement and adjustment, especially in complex systems where it cannot achieve the fine-tuning capabilities of automated balancing equipment. Manual balancing requires operators to spend a lot of time and energy on repeated adjustments and verifications, and in complex systems, it may require multiple attempts to achieve a balanced state. Therefore, an automatic balancing spindle device for valve bevel grinding machines is needed to improve the above problems. Utility Model Content

The positioning component 3 includes a bearing plate 301, a support rod 302 fixedly connected to the top of the bearing plate 301, a top groove 303 fixedly connected to the top of the support rod 302, and a laser emitter 304 mounted on the top of the top groove 303. The horizontal position of the valve bevel grinding machine spindle is positioned by the laser emitter 304 and the receiver 206, which can ensure that the spindle can be balanced more quickly and accurately during automatic balancing. This is a non-contact positioning method that does not require direct contact with the object being measured, thus avoiding damage or interference to the object being measured.

[0028] The device includes two bases 201, two electric actuators 202, and two telescopic rods 203; two placement slots 204, two receivers 206, and two mounting blocks 207; and two bearing plates 301, two support rods 302, two top slots 303, and two laser emitters 304.
