Abstract

The utility model provides a spindle device with cutter lubricating function, this spindle device sets up in the forming machine, have the main shaft and set up in the dust cage of main shaft below, main shaft end-to-end connection has the cutter, the cutter is by the upper and lower displacement of main shaft drive, make the cutter expose the dust cage and then process the work piece, be provided with the shower nozzle for blowout emollient on the dust cage, the shower nozzle is just to the cutter, when making the main shaft drive cutter immigration dust cage, the emollient of shower nozzle spun can lubricate the cutter, and then the life of extension cutter. By means of the nozzle arranged in the dust collection cover of the spindle device, when the spindle drives the cutter to move into the dust collection cover, the cutter is lubricated by using the lubricant sprayed by the nozzle, the problem of cutter adhesion is reduced, and the service life of the cutter is further prolonged.

Description

Spindle device with tool lubricating function

Technical Field

The present invention relates to a spindle device with a tool lubricating function, and more particularly to a spindle device provided in a forming machine for keeping a tool of a spindle lubricated by a lubricant to reduce the occurrence of a tool sticking situation.

Background

In a forming machine, a tool is used to perform operations such as milling or drilling on a workpiece, however, under the condition that the workpiece has low plasticity and low melting point (for example, aluminum material), the tool is prone to generate a tool sticking problem, which results in a great reduction in the chip removal performance of the tool, the roughness of the processing surface of the workpiece is increased, and the tool wear is accelerated, so that there is a related industry that an outer cover is arranged on a main shaft of the forming machine, a lubricant is flowed between the outer cover and the main shaft, and the tool connected with the main shaft is lubricated by the lubricant at any time, so as to reduce the occurrence of the tool sticking, but the method has the following defects:

1. when the tool is formed, the lubricant does not flow to the tip of the tool effectively because the tool is deep into the workpiece, which is not effective and wastes lubricant.

2. Since the lubricant must flow between the outer cover and the main shaft, the structure between the outer cover and the main shaft becomes quite complicated, and the structure of the main shaft must be changed, which cannot be applied to the existing forming machine.

SUMMERY OF THE UTILITY MODEL

The main objective of the present invention is to utilize the nozzle disposed in the dust collecting cover of the spindle device to lubricate the tool by using the lubricant sprayed from the nozzle when the spindle drives the tool to move into the dust collecting cover, thereby reducing the problem of sticking the tool and further prolonging the service life of the tool.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a spindle unit with cutter lubricating function, this spindle unit sets up in the forming machine, has the main shaft and sets up in the dust cage of main shaft below, and main shaft end-to-end connection has the cutter, and the cutter drives upper and lower displacement by the main shaft, makes the cutter expose the dust cage and then processes its characterized in that:

the dust collecting cover is provided with a spray head for spraying lubricant, the spray head is opposite to the cutter, so that when the main shaft drives the cutter to move into the dust collecting cover, the lubricant sprayed by the spray head can lubricate the cutter.

The utility model has the advantages of, can prolong the life of cutter.

Detailed Description

Referring to fig. 1, it can be clearly seen that the spindle device with tool lubricating function of the present invention, which is disposed in a forming machine for processing a workpiece 5, has a spindle 1, a dust cage 2, a tool 3 and a nozzle 4, wherein:

the main shaft 1 is arranged on a forming processing machine, and a tool chuck 11 for locking the tool 3 is arranged at the lower end part of the main shaft 1.

The dust hood 2 is a hollow hood body and is provided with an upper end 21 and a lower end 22, the upper end 21 is arranged at the periphery of the main shaft 1 in a surrounding mode, the lower end 22 is arranged at the lower side of the main shaft 1, the inner wall of the dust hood 2 surrounds the cutter 3 of the tail end device of the main shaft 1, and a processing hole 221 for exposing the dust hood 2 when the cutter 3 moves downwards is arranged at the bottom of the lower end 22, so that the tail end of the cutter 3 is directly opposite to a workpiece 5 at the lower side of the dust hood 2 to process.

The cutter 3 is a milling cutter or a drilling needle (such as an end mill, a face mill, a reamer, a drilling needle, a tapping drilling needle …, etc.), and a locking device is arranged on a cutter chuck 11 at the end of the main shaft 1, so that the cutter 3 is driven by the main shaft 1 to move up and down to perform milling or drilling operations on the workpiece 5.

The nozzle 4 has a nozzle 41 for spraying the lubricant 6 and an inlet pipe 42 for the lubricant 6 at both ends, the nozzle 4 is provided on the inner wall of the dust hood 2, the nozzle 41 faces the cutter 3 in the dust hood 2, the inlet pipe 42 is connected to the outside through the side wall of the dust hood 2, and the lubricant 6 flows in through the inlet pipe 42 and is sprayed from the nozzle 41 of the nozzle 4.

By the aid of the above, please refer to fig. 2 to 3, as can be clearly seen from the drawings, the spindle device with tool lubrication function of the present invention, when the spindle 1 drives the tool 3 to move downward, so that the tool 3 exposes the dust hood 2 from the processing hole 221 and then processes the workpiece 5, after the processing, the spindle 1 drives the tool 3 to move upward in the dust hood 2, the nozzle 4 of the nozzle 41 on the sidewall of the dust hood 2 sprays the lubricant 6 toward the tool 3, so that the lubricant is effectively and directly sprayed on the front end of the tool 3, and further the service life of the tool 3 is prolonged, and the lubricant 6 can greatly reduce the lubricant waste in the injection manner compared with the background technology in the spraying manner, and the structure between the dust hood 2 and the spindle 1 is simple, and the spindle 1 structure does not need to be changed, and the spindle device can be applied to the existing forming machine.
