Technical Field

[0001] This utility model relates to the technical field of spindle boxes, and in particular to a vertical machining center spindle box with a heat dissipation structure. Background Technology

[0002] The spindle box of a vertical machining center is an important component of the machine tool, mainly used to mount the spindle, its transmission parts, and corresponding auxiliary mechanisms. The spindle box includes the spindle assembly, reversing mechanism, transmission mechanism, braking device, operating mechanism, and lubrication device, etc. Its main function is to support the spindle and enable it to rotate, realizing the functions of starting, braking, speed changing, and reversing the spindle.

[0003] Chinese patent document CN102873346B discloses a spindle box structure for a vertical machining center, specifically relating to a modular spindle box structure for a vertical machining center. The technical solution adopted in the aforementioned patent document is as follows: A spindle box structure for a vertical machining center is designed, including a spindle box base, a rigid rail mating plate module, and a linear rail mating plate module. The spindle box base, the rigid rail mating plate module, and the linear rail mating plate module are all equipped with unified positioning and connection interfaces. These interfaces are positioned using side and bottom reference surfaces, tightened with set screws, and connected with screws. Intermittently driven pins serve to repeat positioning and strengthen the fixation. The rigid rail mating plate module and the linear rail mating plate module can be interchanged and reassembled on the spindle box base by disassembling and installing set screws, screws, and pins, thereby designing and manufacturing a rigid rail spindle box and a linear rail spindle box.

[0004] While the aforementioned patent documents can reduce manufacturing costs and facilitate module assembly and disassembly during implementation, they cannot effectively remove heat from the spindle box in a timely manner. Excessive heat leads to energy waste in the spindle box and affects the service life and processing efficiency of the equipment. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1As shown, a vertical machining center spindle box with a heat dissipation structure includes a vertical machining spindle box body 1, an inner box 2 fixedly connected to the middle of the bottom wall of the inner cavity of the vertical machining spindle box body 1, and a cooling component 3 fixedly connected to the middle of the rear end of the outer surface of the vertical machining spindle box body 1, which can achieve multiple cooling treatments for the coolant. A cooling mechanism 4 is installed and fixed in the gap between the inner wall of the vertical machining spindle box body 1 and the outer wall of the inner box 2, which can absorb the heat inside the inner box 2 by injecting coolant. A bearing mechanism 5 is fixedly connected to the middle of the rear end of the outer surface of the 1st spindle box, which can support the heat dissipation component 6. The heat dissipation component 6 is installed and fixed inside the bearing mechanism 5, which can extract the hot air inside the inner cavity of the inner box 2 to the outside in a timely manner. A loading mechanism 7 is fixedly connected to the middle of the left end of the outer surface of the vertical machining spindle box body 1, which can load the dustproof mechanism 8. The dustproof mechanism 8 is movably connected to the left side inside the loading mechanism 7, which can filter and intercept dust and other impurities contained in the air entering the inner cavity of the inner box 2.

[0024] To achieve the goal of multiple cooling processes for the coolant, see [reference needed]. Figure 2 The refrigeration component 3 includes a refrigeration unit 31. A liquid injection pipe 32 is fixedly connected to the front input end of the outer surface of the refrigeration unit 31, which can realize the function of injecting or discharging coolant into the inner cavity of the refrigeration unit 31. A liquid outlet pipe 33 is symmetrically fixedly connected to the upper and lower middle parts of the outer surface of the refrigeration unit 31, which can realize the function of circulating and transporting coolant in the inner cavity of the coolant return pipe 42.

[0025] To achieve the goal of absorbing heat from the interior of the inner casing 2 by injecting coolant, refer to... Figure 2 The cooling mechanism 4 includes several fixed housings 41, and the inner cavities of the several fixed housings 41 are all fixedly connected to a coolant return pipe 42. This allows the coolant circulating through the inner cavity of the coolant return pipe 42 to absorb the heat dissipated from the inner cavity of the inner box 2. The upper input end of the coolant return pipe 42 is fixedly connected to the upper output end of the upper outlet pipe 33, and the lower output end of the coolant return pipe 42 is fixedly connected to the lower output end of the lower outlet pipe 33.

[0026] To achieve the purpose of supporting the heat dissipation component 6, see [reference needed]. Figure 3 The bearing mechanism 5 includes a bearing housing 51. A protective frame 52 is fixedly connected to the left side of the inner cavity of the bearing housing 51, which can bear and protect the servo motor 61. A support frame 53 is fixedly connected to the right side of the inner cavity of the bearing housing 51, which can support the fan blade 62.

[0027] To achieve the goal of timely extraction of hot air from the inner cavity of inner chamber 2 to the outside, refer to... Figure 3The heat dissipation component 6 includes a servo motor 61, with a fan blade 62 fixedly connected to the right output end of the servo motor 61. The servo motor 61 is installed and fixed in the middle of the inner cavity of the protective frame 52, and the fan blade 62 is rotatably connected to the middle of the support frame 53.

[0028] By driving the servo motor 61 to rotate the fan blade 62, the hot air inside the inner box 2 can be extracted to the outside in time. Through the effect of balancing the internal and external air pressure, the outside air can pass through the inner cavity of the fixed frame 71 and enter the inner cavity of the inner box 2.

[0029] To achieve the purpose of installing the dustproof mechanism 8, please refer to... Figure 4 The loading mechanism 7 includes a fixed frame 71. Several horizontal plates 72 are fixedly connected at intervals on the right side of the inner cavity of the fixed frame 71. Positioning holes 73 are opened at the four corners of the inner wall of the fixed frame 71, which can cooperate with the corresponding hemispherical block 85 to clamp the rectangular frame 81 in the left side of the inner cavity of the fixed frame 71.

[0030] To achieve the purpose of filtering and intercepting dust and other impurities in the air entering the inner chamber 2, please refer to... Figure 4 The dustproof mechanism 8 includes a rectangular frame 81. A dustproof net 82 is installed and fixed on the left side of the inner cavity of the rectangular frame 81. Vertical plates 83 are symmetrically fixed to the right wall of the inner cavity of the rectangular frame 81. Spring plates 84 are provided in the upper and lower inner cavities of the two vertical plates 83. Hemispherical blocks 85 are fixedly connected to the outer surfaces of several spring plates 84 on the opposite sides of each other. The outer surface of the rectangular frame 81 is slidably connected to the left side of the inner cavity of the fixed frame 71. Several hemispherical blocks 85 are movably connected to the inner cavities of the corresponding positioning holes 73.

[0031] When the rectangular frame 81 needs to be installed in the inner cavity of the fixed frame 71, hold the rectangular frame 81 and slowly slide the outer surfaces of the two vertical plates 83 along the inner wall of the inner cavity of the fixed frame 71 to the right. During this process, several hemispherical blocks 85 will be squeezed by the inner wall of the fixed frame 71 and will push the corresponding spring plates 84 to contract. This allows the hemispherical blocks 85 to contract with the spring plates 84 into the inner cavity of the corresponding vertical plates 83. When the vertical plates 83 have completely slid into the inner cavity of the fixed frame 71, the hemispherical blocks 85 will be locked in the inner cavity of the positioning holes 73 that are aligned with their positions under the rebound force of the corresponding spring plates 84. This will lock the rectangular frame 81 in the left part of the inner cavity of the fixed frame 71.

[0032] It should be noted that the model of the refrigeration unit 31 in this utility model is ZGLY-17ALC, and the model of the servo motor 61 is Siemens 1FT7. The specific installation method, circuit connection method and control method of the refrigeration unit 31 and the servo motor 61 are all conventional designs, and this utility model will not describe them in detail.

[0033] The working principle of this utility model is as follows: When heat dissipation is required in the inner cavity of the inner box 2, an appropriate amount of coolant is first injected into the inner cavity of the refrigeration unit 31 through the injection pipe 32. Under the braking of the refrigeration unit 31, the coolant is injected into the inner cavity of the upper outlet pipe 33, allowing the coolant to circulate from top to bottom along the inner cavity of the coolant return pipe 42. During the flow, the coolant absorbs the heat generated by the relevant mechanical components in the inner cavity of the inner box 2. The coolant flowing downward along the inner cavity of the coolant return pipe 42 will return to the inner cavity of the refrigeration unit 31 through the lower outlet pipe 33. After the refrigeration unit 31 cools the coolant again, it is transported back to the inner cavity of the coolant return pipe 42 through the upper outlet pipe 33, thereby fully absorbing the heat dissipated from the inner cavity of the inner box 2. Meanwhile, by driving the servo motor 61 to drive the fan blade 62 to start rotating in the left part of the inner cavity of the bearing housing 51, the residual heat in the inner cavity of the inner box 2 can be extracted to the outside in time. During this period, the outside air will pass through the inner cavity of the fixed frame 71 and enter the inner cavity of the inner box 2. Furthermore, the dust and other impurities contained in the air that passes through the inner cavity of the fixed frame 71 and enters the inner cavity of the inner box 2 will be filtered and intercepted by the dustproof net 82. When it is necessary to clean or replace the dustproof net 82, the rectangular frame 81 is slowly pulled to the left, so that several hemispherical blocks 85 that are locked in the inner cavity of the positioning hole 73 squeeze the corresponding spring plates 84, thereby compressing the several spring plates 84 and causing the several hemispherical blocks 85 to release the positioning of the rectangular frame 81, so that the dustproof net 82 can be cleaned or replaced.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
