Problems solved by technology

[0003] Most of the existing spindle boxes are fixed on the base by bolts and nuts, which is not convenient enough to disassemble and assemble, which makes the maintenance of the spindle box more troublesome, and the coolant of the spindle box is transported through pipelines, which is not simple enough, and is prone to water leakage. Iron filings are not easy to collect, which makes it difficult to clean the machine tool

Embodiment 1

[0029] refer to Figure 1-6 , a spindle box of a precision numerical control machine tool, comprising a spindle box body 1 and a base 4, the spindle box body 1 is detachably mounted on the top of the base 4, one side of the spindle box body 1 is provided with a motor mounting plate 2, and a motor mounting plate 2 It is used to install the spindle motor. One side of the spindle box body 1 is located under the motor mounting plate 2. There is a knife cylinder mounting seat 3. The knife cylinder mounting seat 3 is used to fix the knife cylinder. With a new design, the spindle motor Put it on the top of the headstock body 1, and put the cutter cylinder under the headstock body 1, which changes the structure of the traditional headstock body and is easier to install. The top of the headstock body 1 is provided with a coolant inlet 50, and the headstock body 1 A spray ring 52 is installed on the side away from the motor mounting plate 2, and the spray ring 52 communicates with the c...

Embodiment 2

[0031] refer to Figure 1-6The difference between this embodiment and Embodiment 1 is that both sides of the bottom end of the spindle box body 1 are fixedly connected with positioning support blocks 9, and the top of the base 4 is provided with positioning slots corresponding to the positioning support blocks 9, and the positioning support blocks 9 extends into the positioning slot, the top of the base 4 is respectively provided with a first installation cavity 5 and a second installation cavity 6, two second installation cavities 6 are provided, and the two second installation cavities 6 are distributed with the first installation cavity On both sides of the chamber 5, two-way threaded rods 7 are installed in rotation between the inner walls on both sides of the first installation chamber 5, and two first threaded sleeves 12 are installed on the outer threads of the two-way threaded rods 7. The top end is fixedly connected with the first moving riser 11, and the first guide ...

Embodiment 3

[0035] refer to Figure 1-6 The difference between this embodiment and Embodiment 1 is that the top of the base 4 is provided with an iron filings collection groove 26, and the bottom inner wall of the iron filings collection groove 26 is provided with a chip removal groove 27, and the width of the chip removal groove 27 is smaller than that of the iron filings. The width of the collection tank 26, the larger diameter of the iron filings collection tank 26 can collect more iron filings, prevent the iron filings from scattering to the outside of the iron filings collection tank 26, and one side of the base 4 is fixedly equipped with a rotating motor 28, which rotates The output end of the motor 28 is fixedly connected with a conveying screw 29, the conveying screw 29 is located in the chip removal groove 27, the side of the base 4 away from the rotating motor 28 is fixedly connected with a storage cylinder 30, the storage cylinder 30 communicates with the chip removal groove 27,...

Abstract

The invention relates to the technical field of machine tools, and discloses a spindle box of a precise numerical control machine tool. The spindle box comprises a spindle box body and a base, the spindle box body is detachably mounted at the top end of the base, a motor mounting plate is arranged on one side of the spindle box body, and an unclamping cylinder mounting seat is arranged on one side of the spindle box body and located below the motor mounting plate. The spindle box is ingenious in structure and convenient to use, the spindle box body is convenient to disassemble and assemble, the spindle box can be conveniently overhauled, scrap iron can be automatically collected in a centralized mode, convenience is brought to cleaning of the scrap iron, the spindle motor is placed on the spindle box body, an unclamping cylinder is placed below the spindle box body, the structure of a traditional spindle box is changed, mounting is more convenient, a cooling liquid conveying channel and a spraying ring are integrated in the spindle box body, external pipelines are reduced, water leakage is avoided, a lathe bed looks more concise, a closed spindle nut seat is adopted, the more stable effect is achieved in the machining process, and vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a spindle box of a precision numerical control machine tool. Background technique [0002] The spindle box is an important part of the CNC machine tool, which is used to arrange the working spindle of the machine tool and its transmission parts and corresponding additional mechanisms. The headstock is a complex transmission part, including the main shaft assembly, reversing mechanism, transmission mechanism, braking device, operating mechanism and lubrication device, etc. Its main function is to support the main shaft and make it rotate, so as to realize the functions of main shaft starting, braking, speed changing and reversing. [0003] Most of the existing spindle boxes are fixed on the base by bolts and nuts, which is not convenient enough to disassemble and assemble, which makes the maintenance of the spindle box more troublesome, and the coolant of the spindle box is...
