Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing technology, and specifically relates to a milling machine lubrication device. Background Technology

[0002] The limited space at the bottom of the milling machine's travel rail makes lubrication and maintenance difficult. Lack of regular lubrication can lead to hard friction on the rail, causing equipment damage. Current maintenance involves manual, periodic lubrication. During operation, the oil filling hole on the milling machine is opened, and oil is injected through a lubrication device. The existing lubrication device is semi-automatic; after the operator powers on the pump, it draws lubricant from the oil tank and then injects it into the oil filling hole through an oil pipeline.

[0003] Due to the narrow space at the bottom of the travel rail, the machine bed needs to be disassembled to complete lubrication and maintenance. A single lubrication and maintenance operation takes 12 hours, and lubrication and maintenance must be carried out at least twice a year. Therefore, lubrication and maintenance work seriously affects production efficiency. Summary of the Invention

[0015] An oil passage hole is provided at the lower side of the connecting block, and the oil pipeline is connected to the pump through the oil passage hole.

[0016] Since the equipment operates on the milling machine for extended periods, a housing is installed to protect the pump body, control module, display module, and button module.

[0017] Furthermore, the lower cover and the upper cover are fixed together by bolts, and a fixing block is provided at the bottom of the lower cover, the fixing block being square.

[0033] An oil passage hole is provided at the lower side of the connecting block 15, and the oil pipeline 3 is connected to the pump 2 through the oil passage hole.

[0034] The lower cover and the upper cover are fixed together by bolts. A fixing block 16 is provided at the bottom of the lower cover. The fixing block 16 is square.

[0035] The mounting plate 9 is an L-shaped plate. A baffle 17 is provided on the horizontal section of the mounting plate 9. The baffle 17 is a straight plate. The baffle 17 and the mounting plate 9 are an integrated structure. The baffle 17 is fixed to the side of the fixing block 16 by bolts. A through hole is opened on the vertical section of the mounting plate 9.

[0036] During installation, a through hole is drilled on the milling machine corresponding to the through hole of the mounting plate 9, and the vertical section of the mounting plate 9 is fixed to the milling machine with bolts. Lubricant is added to the oil reservoir 1 through the oil filling port of the oil reservoir 1. Then, the oil reservoir 1 is threaded to the connecting block 15.

[0037] After installation, set the oiling frequency via button module 11; in this example, it is set to once every six months. View and verify the commands output by button module 11 via display module 10.

[0038] The control module includes an MCU chip 12, a driver chip 13, a driver circuit 14, and a power supply module.
