Description

Technical Field

[0001] This utility model belongs to the field of wind power processing equipment, specifically designing an automatic adjustment device for the spindle of an end milling machine. Background Technology

[0002] As the global wind power industry moves towards high-power units, wind turbine blade lengths have exceeded 100 meters, and the pitch circle diameter (i.e., the bolt distribution circle on the flange end face) of the blade root connection has increased to over 3 meters. This requires blade end face milling machines to have a larger machining stroke and a wider spindle position adjustment range. Traditional adjustment methods have the following drawbacks: Currently, spindle position adjustment mainly relies on manual operation, posing a risk of working at height. Operators need to climb to the machine tool beam area, several meters high, to manually loosen the locking mechanism, push the spindle assembly to position, and then relock it, posing a risk of falling from height; adjustment efficiency is low, with a single adjustment taking 15-30 minutes and requiring repeated measurements and verification, seriously affecting the batch processing of large blades; adjustment accuracy is insufficient, as manual visual inspection and tool positioning are prone to errors, failing to meet the high-precision flange end face processing requirements of blades. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an automatic adjustment device for the spindle of an end milling machine.

[0004] The technical solution adopted in this utility model includes: The crossbeam is connected to the top of the milling machine; The lateral adjustment assembly includes a lateral slide rail connected along the length of the beam and a lateral slide plate that slides with the lateral slide rail; The longitudinal adjustment assembly includes a longitudinal slide rail connected to the transverse slide plate and a longitudinal slide plate that slides with the longitudinal slide rail, the top of the longitudinal slide plate being used to mount a milling machine spindle tool set; A lateral drive component is used to drive the lateral sliding plate to move along the lateral slide rail; A longitudinal drive member is used to drive the longitudinal sliding plate to move along the longitudinal slide rail.

[0005] As a preferred embodiment of this utility model, the bottom of the transverse sliding plate is fixedly provided with a first fixing block that cooperates with the transverse driving member and a transverse slider that slides with the slide rail.

[0006] As a preferred embodiment of the present invention, the transverse drive component includes a first lead screw rotatably connected to the crossbeam via a shaft seat and a first drive component pulsator connected to one end of the lead screw. The first lead screw cooperates with the first fixed block lead screw, and a corrugated protective sleeve is fitted on the first lead screw.

[0007] As a preferred embodiment of this invention, the first driving component is a drive motor and a handwheel connected to the other end of the lead screw.

[0008] As a preferred embodiment of this utility model, the bottom of the longitudinal sliding plate is fixedly provided with a second fixing block that slides in cooperation with the longitudinal slide rail and a longitudinal slider that slides in cooperation with the longitudinal slide rail.

[0009] As a preferred embodiment of the present invention, the longitudinal drive component includes a second lead screw rotatably connected to the transverse sliding plate via a shaft seat and a second drive component pulsator connected to one end of the second lead screw. The second lead screw cooperates with the lead screw of the second fixed block, and a corrugated protective sleeve is fitted on the second lead screw.

[0010] As a preferred embodiment of this invention, the second driving component is a drive motor.

[0011] The beneficial effects of this utility model are as follows: This invention is an automatic adjustment device for the spindle of an end milling machine. The spindle tool assembly is adjustable in both the lateral and longitudinal directions on the crossbeam using a lateral adjustment component and a longitudinal adjustment component. This allows the actual position of the spindle tool assembly to be adjusted according to the diameter of the blade root pitch circle. By setting up lateral and longitudinal drive components, the lateral and longitudinal adjustment components are automatically adjusted, replacing the need for operators to climb several meters into the air to manually adjust the lateral and / or longitudinal position of the spindle tool assembly on the crossbeam. This effectively improves both adjustment efficiency and accuracy. Attached Figure Description
