Description

Technical Field

[0001] This utility model relates to the field of spindle box technology, and in particular to a spindle box. Background Technology

[0002] The spindle box is a crucial component of a machine tool, housing the machine tool's working spindle, its transmission parts, and corresponding auxiliary mechanisms. It transmits the motor's rotational power to the spindle via multi-stage gear transmission, enabling the spindle to rotate. A speed-changing mechanism alters the transmission ratio, adjusting the spindle speed to accommodate different materials, cutting tools, and machining processes, thereby improving machining efficiency and quality. Bearings and other components provide stable support to the spindle, maintaining its stability and accuracy, ensuring no excessive deviation or vibration during rotation, thus guaranteeing machining precision. It connects to other related components, such as the tool post and tailstock, enabling them to work collaboratively to complete various machining tasks. Clutches and other devices change the spindle's rotation direction to meet different machining needs; for example, when turning internal and external threads, the spindle needs to switch between forward and reverse rotation.

[0003] Chinese Patent Publication No. CN220445062U discloses a spindle box with through holes in its side walls, two of which are arranged opposite each other. It also includes a rotating shaft composed of a mandrel and a spacer. The mandrel passes through one through hole and connects to the spacer. The spacer has an eccentric tube that passes through another through hole and is fitted around the outside of the mandrel. The spacer rotates relative to the mandrel to correct their concentricity. In this utility model, the rotating shaft is composed of a spacer and a mandrel, and the spacer has an eccentric tube. By connecting the eccentric tube to the mandrel and rotating relative to it, the inner wall of the eccentric tube presses against the mandrel, causing a slight offset of the mandrel. This corrects the concentricity between the mandrel and the spacer, reducing the deviation between the centers of the two through holes, solving the problems existing in the prior art, improving accuracy, and further expanding the applicability of the spindle box.

[0004] For existing spindle boxes, in actual use, when the spindle is transmitting power, it is easy for friction to occur between the spindle and the spindle box due to rotation, which will cause wear on the spindle and reduce its service life. Furthermore, when cooling the spindle box, the heat dissipation equipment occupies a large space and is not convenient to fix, which affects the heat dissipation effect of the spindle box. Utility Model Content

[0005] The purpose of this invention is to provide a spindle box that solves the problems in the prior art where the spindle box easily causes wear on the spindle due to friction, leading to spindle damage, and it is also inconvenient to use large heat dissipation equipment to cool the spindle box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spindle box includes a housing, a stabilizing groove on one side of the housing, a lubrication mechanism inside the stabilizing groove, a receiving groove on one side of the housing, a heat dissipation plate inside the receiving groove, a sleeve fixedly connected to one side of the heat dissipation plate, a condensing plate inside the sleeve via an installation mechanism, the surface of the condensing plate fixedly connected to the side of the housing, and a heat-conducting block fixedly connected to the surface of the heat dissipation plate, the heat-conducting block being located between the condensing plate and the heat dissipation plate.

[0008] Preferably, the lubrication mechanism includes an outer ring rotatably connected inside the stabilizing groove, an inner ring inside the outer ring, and a plurality of balls slidably connected between the outer ring and the inner ring.

[0009] Preferably, the outer ring surface has a plurality of oil supply grooves and a through groove that communicates with the plurality of oil supply grooves.

[0010] Preferably, the outer ring has two sealing grooves on its surface, with a through groove located between the two sealing grooves, and a sealing ring fixedly connected inside the sealing groove.

[0011] Preferably, the installation mechanism includes a drying cylinder communicating with the surface of the condenser plate, and two elastic plates are fixedly connected to the surface of the sleeve, with the drying cylinder located between the two elastic plates.

[0012] Preferably, a U-shaped receiving block is fixedly connected to the surface of the sleeve, and a T-shaped insertion block is fixedly connected to the surface of the drying cylinder, with the insertion block located inside the receiving block.

[0013] This utility model has the following beneficial effects:

[0014] When using the spindle box, the outer and inner rings work together to lubricate the spindle and the stabilizing groove, thereby reducing the friction between the spindle and the stabilizing groove, making the spindle less prone to wear and ensuring its service life. In addition, the heat sink and condenser plate work together to dissipate heat from the inside of the box. The condenser and heat sink components are compact, minimizing the space occupied, thus facilitating heat dissipation from the inside of the box. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A spindle housing includes a housing 1. A stabilizing groove 2 is provided on one side of the housing 1. The spindle transmits internal power to external equipment through the stabilizing groove 2. A lubrication mechanism 3 is provided inside the stabilizing groove 2. The lubrication mechanism 3 reduces friction between the spindle and the stabilizing groove 2, thereby reducing force loss due to friction and minimizing damage caused by friction, allowing the spindle to be used for a longer period and improving its service life. A receiving groove 4 is provided on one side of the housing 1. A heat dissipation plate 5 is provided inside the receiving groove 4, facilitating the insertion of the heat dissipation plate 5 into the housing 1 for heat absorption. A sleeve 6 is fixedly connected to one side of the heat dissipation plate 5. A condensation plate 8 is provided inside the sleeve 6 via an installation mechanism 7. Condensate flows inside the condensation plate 8. The heat from the heat sink 5 is conveniently absorbed and then discharged by the condenser plate 8. The condenser plate 8 is fixed inside the sleeve 6 by the mounting mechanism 7, reducing space requirements and ensuring that the condenser and heat sink are compact and facilitate heat transfer. The surface of the condenser plate 8 is fixedly connected to the side of the housing 1. By fixing the condenser plate 8 to the outside of the housing 1, the heat sink 5 is confined inside the housing 1, so that the heat sink 5 will not change position when dissipating heat. It can stably absorb the heat generated by the internal structure of the housing 1 during use. A heat-conducting block 9 is fixedly connected to the surface of the heat sink 5. The heat-conducting block 9 is located between the condenser plate 8 and the heat sink 5. The heat-conducting block 9 can conveniently transfer the heat absorbed by the heat sink 5 to the condenser plate 8, and then be absorbed by the condensate in the condenser plate 8, thereby conveniently cooling the inside of the housing 1.

[0024] Furthermore, the lubrication mechanism 3 includes an outer ring 301 rotatably connected inside the stabilizing groove 2. An inner ring 302 is provided inside the outer ring 301. A plurality of balls 303 are slidably connected between the outer ring 301 and the inner ring 302. The outer ring 301 and the inner ring 302 are connected by the balls 303. There is a groove on the side of the outer ring 301 and the inner ring 302 near the balls 303. The balls 303 are located inside the groove and can hold the inner ring 302 inside the outer ring 301. Thus, the spindle is inserted into the inner ring 302, so that the rotation of the spindle can be lubricated by the balls 303, the inner ring 302 and the outer ring 301, to prevent the rotation of the spindle from being damaged by friction and to prevent friction from damaging the spindle and affecting its service life.

[0025] Furthermore, the outer ring 301 has several oil supply grooves 304 on its surface and a through groove 305 on its surface, which communicates with the oil supply grooves 304. When it is necessary to apply lubricating oil to the outer ring 301, the inner ring 302, and the balls 303, the oil from the outer ring 301 can easily enter the balls 303 through the oil supply grooves 304. When applying oil, the through grooves 305 can also connect the oil supply grooves 304, allowing oil to easily enter the interior of other oil supply grooves 304 to supply oil to the balls 303. This ensures the lubrication of the spindle during use, guarantees stable lubrication, and reduces vibration and noise.

[0026] Furthermore, two sealing grooves 306 are formed on the surface of the outer ring 301, and the through groove 305 is located between the two sealing grooves 306. A sealing ring 307 is fixedly connected inside the sealing groove 306. When the outer ring 301 rotates inside the stabilizing groove 2 to facilitate the rotation of the spindle, the through groove 305 can be sealed by the contact between the sealing ring 307 inside the sealing groove 306 and the stabilizing groove 2.

[0027] Furthermore, the installation mechanism 7 includes a drying cylinder 701 connected to the surface of the condenser plate 8. Two elastic plates 702 are fixedly connected to the surface of the sleeve 6. The drying cylinder 701 is located between the two elastic plates 702. When it is necessary to install the condenser plate 8 and the heat sink 5, the drying cylinder 701 can be inserted between the elastic plates 702 on the sleeve 6. The elastic force of the two elastic plates 702 squeezes the surface of the drying cylinder 701, so that the elastic plates 702 can clamp and fix the drying cylinder 701 through friction, thereby facilitating the fixing of the condenser plate 8 and the heat sink 5. A part of the drying cylinder 701 will enter the interior of the sleeve 6, and the sleeve 6 will provide a certain degree of protection for the drying cylinder 701.

[0028] Furthermore, a U-shaped receiving block 703 is fixedly connected to the surface of the sleeve 6, and a T-shaped insertion block 704 is fixedly connected to the surface of the drying cylinder 701. The insertion block 704 is located inside the receiving block 703. When the sleeve 6 needs to be installed on the elastic plate 702, the condensing plate 8 needs to be moved upward first so that the insertion block 704 is aligned with the inside of the receiving block 703. Then, the sleeve 6 is pressed against the elastic plate 702. During the pressing process, the sleeve 6 is lowered so that the insertion block 704 enters the inside of the receiving block 703. This allows the sleeve 6 to be stably restricted between the elastic plates 702, making the condensing plate 8 and the heat dissipation plate 5 more stable. This saves installation space without affecting the heat dissipation of the housing 1.

[0029] In summary:

[0030] When using the spindle box, which transmits power to the outside of the housing 1 via the spindle, lubrication is required between the stabilizing groove 2 and the spindle via the lubrication mechanism 3. This prevents friction between the spindle and the stabilizing groove 2 from affecting transmission and also prevents wear and tear on the spindle that could shorten its service life. During lubrication, the outer ring 301, inner ring 302, and balls 303 work together to reduce friction during spindle rotation, facilitating transmission and reducing wear on the spindle, thus extending its service life. When oil needs to be applied to the outer ring 301, it can be supplied through the oil supply groove 3. 04 facilitates the entry of lubricating oil into the inner ring 301 to lubricate the balls 303, and also allows the through groove 305 to connect several oil supply grooves 304, facilitating the lubrication of other oil supply grooves 304. Furthermore, the outer ring 301 and the stabilizing groove 2 are sealed by the sealing ring 307 inside the sealing groove 306. When the mechanism inside the housing 1 is in use, heat dissipation is achieved through the heat dissipation plate 5 inside the receiving groove 4 in conjunction with the condenser plate 8, thereby reducing the internal temperature of the housing 1 and ensuring the normal operation of the internal structure. During use, the condenser plate 8 needs to be fixed... Fixed to the surface of the housing 1, the heat dissipation plate 5 can easily enter the interior of the housing 1 for heat dissipation. The condensing plate 8 conducts heat quickly through the heat-conducting block 9, allowing the heat absorbed by the heat dissipation plate 5 to be transferred to the condensing plate 8, facilitating heat dissipation inside the housing 1. When it is necessary to assemble the condensing plate 8 with the heat dissipation plate 5, the drying cylinder 701 can be moved towards the interior of the sleeve 6. First, the insertion block 704 is inserted into the interior of the receiving block 703 from top to bottom. Then, the drying cylinder 701 can squeeze the elastic plate 702, so that while part of the drying cylinder 701 enters the interior of the sleeve 6, it is also squeezed by the elastic plate. Plate 702 is pressed and fixed to ensure stability, allowing the condenser plate 8 and heat sink 5 to be easily fixed together, reducing space requirements and facilitating heat dissipation inside the housing 1. Through the above structure, when using the spindle box, the outer ring 301, inner ring 302, and rollers can be easily lubricated between the spindle and the stabilizing groove 2, ensuring safety. Furthermore, during use, the condenser plate 8 and heat sink 5, which occupy relatively little space, can dissipate heat, reducing the temperature inside the housing 1 during operation and ensuring the normal operation of the internal structure of the housing 1.
