Its spindle is an electric spindle that can be processed at high speed on the glass engraving machine. The spindle is mainly used for high-speed engraving, drilling, milling and punching of glass.

[0003] The existing spindle structure of the glass engraving machine has a traditional spindle motor which is usually placed between the front and rear bearings of the spindle.

[0009] Furthermore, two groups of first rotating shafts are provided, and the two groups of first rotating shafts are symmetrically arranged.

[0011] Furthermore, two partitions are arranged inside the cavity, and the two partitions are evenly and equidistantly distributed.

[0012] By adopting the above technical solution and setting the partition in the cavity, the cavity can be divided into three parts with uniform and equal distances, and the cooling effect can be ensured through three-stage cooling.

[0015] Furthermore, the mesh of the breathable net is relatively fine, and the surface of the breathable net is coated with a nano coating.

[0016] By adopting the above technical solution, the provision of the breathable net can not only ensure a smooth air circulation path between the inside and outside of the fixing seat, but also intercept impurities in the air when the air flows from the outside into the fixing seat, thereby ensuring the cleanliness of the inside of the fixing seat.

[0019] Furthermore, the main gear is fixedly connected to the first rotating shaft, and the main gear is meshed with the slave gear.

[0026] 1.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A glass engraving machine spindle structure, such as Figure 1-Figure 5 As shown, it includes a main shaft body 1, a sealing sleeve 2, a cavity 3 and a fixing seat 4, a heat dissipation mechanism 5 is arranged inside the fixing seat 4, and the heat dissipation mechanism 5 includes a breathable net 501 and a refrigeration box 502, a servo motor 503 is arranged on one side of the refrigeration box 502, a first rotating shaft 506 is arranged on the output end of the servo motor 503, and a stirring blade 508 is arranged on the first rotating shaft 506, and a circulating oil pump 510 is arranged on the side of the refrigeration box 502 away from the servo motor 503, and a first conduit 511 and a second conduit 512 are respectively arranged on both sides of the sealing sleeve 2, and a collecting pipe 513 is arranged at the bottom of the second conduit 512, which collects A connecting pipe 514 is provided on one side of the tube 513, and oil coolant is provided inside the cavity 3 and the refrigeration box 502. The setting of the sealing sleeve 2 and the heat dissipation mechanism 5 can perform oil cooling and heat dissipation on the spindle body 1 and the spindle motor inside it, so that it can be effectively cooled, thereby avoiding excessive heat from having a significant impact on the processing efficiency and effect of the glass engraving machine spindle. The circulating oil pump 510 can make the oil coolant in the sealing sleeve 2 and the refrigeration box 502 continuously circulate, ensuring that the oil coolant can promptly take away the high temperature generated by the spindle body 1 and the spindle motor inside it during operation, so that the heat dissipation process can continue.

[0038] See also Figure 2 , Figure 3 , Figure 4 The servo motor 503 is fixedly connected to the first rotating shaft 506, the first rotating shaft 506 is fixedly connected to the stirring blade 508, the first rotating shaft 506 is rotationally connected to the refrigeration box 502, and the main shaft body 1 is rotationally connected to the sealing sleeve 2. When the servo motor 503 is started, it drives the first rotating shaft 506 fixedly connected thereto to rotate, and further rotates the stirring blade 508 fixedly connected to the first rotating shaft 506, so that the oil coolant in the refrigeration box 502 contacts the inner wall of the refrigeration box 502 as soon as possible during the flow process, and effectively cools down. At the same time, due to the rotation connection between the first rotating shaft 506 and the refrigeration box 502 and the rotation connection between the main shaft body 1 and the sealing sleeve 2, the rotation process of the first rotating shaft 506 will not be affected by the refrigeration box 502, and the presence of the sealing sleeve 2 and the heat dissipation mechanism 5 will not affect the main shaft body 1.

[0039] See also Figure 3 There are two groups of first rotating shafts 506, and the two groups of first rotating shafts 506 are symmetrically arranged. Each group of first rotating shafts 506 has a plurality of stirring blades 508, and the plurality of stirring blades 508 are evenly and equidistantly distributed. The symmetrically arranged first rotating shafts 506 and the plurality of evenly and equidistantly distributed stirring blades 508 can fully stir the oil coolant entering the refrigeration box 502 for cooling, increase the chance of contacting the oil coolant with other low-temperature coolants or the inner wall of the refrigeration box 502, thereby reducing the temperature as quickly as possible, so that with the assistance of the circulating oil pump 510, the spindle body 1 and the spindle motor inside it can be effectively cooled continuously.

[0040] See also Figure 4 Two partitions are arranged inside the cavity 3, and the two partitions are evenly and equidistantly distributed. The arrangement of the partitions in the cavity 3 can divide the cavity 3 into three evenly and equidistant parts, and the cooling effect is ensured through three-stage cooling. Compared with the method without setting the partitions, the oil coolant with lower temperature is injected into the cavity 3 of the sealing sleeve 2 from three parts, and the running path of the oil coolant is shorter. Due to the excessively long running path of the oil coolant, the oil coolant at the end of the running path has been significantly heated up, resulting in obviously inconsistent cooling effects at both ends.

[0041] See also Figure 2 , Figure 3The first conduit 511 and the second conduit 512 are both connected to the cavity 3, the second conduit 512 is connected to the collecting pipe 513, the collecting pipe 513 is connected to the output end of the circulating oil pump 510 through the connecting pipe 514, and the input end of the circulating oil pump 510 is connected to the refrigeration box 502. The circulating oil pump 510 can be used to pump the oil coolant cooled in the refrigeration box 502 into the cavity 3 through the connecting pipe 514, the collecting pipe 513 and the second conduit 512 connected to the circulating oil pump 510. The oil coolant with increased temperature in the cavity 3 passes through the first conduit 511 connected to the cavity 3 and enters the refrigeration box 502 for cooling with the assistance of the circulating oil pump 510.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The mesh of the breathable net 501 is relatively fine, and the surface of the breathable net 501 is coated with a nano coating. The setting of the breathable net 501 can not only ensure the smooth existence of the air circulation path between the inside and outside of the fixing seat 4, but also intercept impurities in the air when the air flows from the outside into the inside of the fixing seat 4, thereby ensuring the cleanliness of the inside of the fixing seat 4. The relatively fine mesh of the breathable net 501 can intercept most impurities in the air and prevent them from entering the fixing seat 4. The setting of the nano coating on the surface of the breathable net 501 makes it difficult for the surface of the breathable net 501 to hide dirt, making it convenient for the staff to clean it.

[0043] Embodiment 2:

[0044] See also Figure 2 , Figure 3 A main gear 504 is provided at one end of the first rotating shaft 506 close to the servo motor 503, and second rotating shafts 507 are provided on both sides of the refrigeration box 502. A slave gear 505 is provided at one end of the second rotating shaft 507, and a fan blade 509 is provided at one end of the second rotating shaft 507 away from the slave gear 505. The arrangement of the main gear 504 and the slave gear 505 allows only one servo motor 503 to drive the two rotating shafts, as well as the stirring blades 508 and the fan blades 509 on the two rotating shafts to rotate simultaneously. The arrangement of the fan blades 509 can force the air in the fixed seat 4 to flow, thereby increasing its flow speed to a certain extent, so that it can smoothly exchange heat with the outside air during the circulation process.

[0045] See also Figure 2 , Figure 3The main gear 504 is fixedly connected to the first rotating shaft 506, and the main gear 504 is meshed with the slave gear 505. When the first rotating shaft 506 rotates smoothly under the action of the servo motor 503, the main gear 504 fixedly connected to the first rotating shaft 506 is driven to rotate, thereby causing the slave gear 505 meshed with the main gear 504 to rotate. Only an electrical component such as a servo motor 503 is needed, and the meshing connection between the main gear 504 and the slave gear 505 can make the stirring blades 508 and the fan blades 509 on the two rotating shafts rotate at the same time, thereby playing different roles of the two.

[0046] See also Figure 3 , the slave gear 505 is fixedly connected to the second rotating shaft 507, the second rotating shaft 507 is rotatably connected to the fixed seat 4, and the fan blade 509 is fixedly connected to the second rotating shaft 507. When the slave gear 505 rotates smoothly under the meshing connection of the main gear 504, it drives the second rotating shaft 507 fixedly connected to the slave gear 505 to rotate smoothly. The existence of the fixed seat 4 does not affect the rotation process of the second rotating shaft 507, and the smooth rotation of the second rotating shaft 507 further makes the second rotating shaft 507 passing through the slave gear 505 drive the fan blade 509 to rotate, thereby accelerating the circulation of air between the inside of the fixed seat 4 and the outside world.

[0047] See also Figure 3 There are multiple fan blades 509, and the multiple fan blades 509 are evenly and equidistantly distributed. The arrangement of the multiple fan blades 509 enables the fan blades 509 to force the air to flow at multiple positions of the length extension line of the fixed seat 4. These fan blades 509 are evenly and equidistantly distributed, so that there are fan blades 509 with the same interval to stir the air, ensuring that the range of action of two adjacent fan blades 509 on stirring the air complements each other.

[0048] The implementation principle of the utility model is as follows: first, when the main spindle body 1 is working, the main spindle body 1 and the spindle motor inside it generate heat, and the heat is transferred to the cavity 3 of the outer sealing sleeve 2 thereof, and is cooled by the oil coolant therein. When the temperature of the oil coolant rises, the circulating oil pump 510 re-injects the oil coolant in the refrigeration box 502, which has been cooled, into the cavity 3 through the second conduit 512, the collecting pipe 513 and the connecting pipe 514, and the oil coolant in the cavity 3 enters the refrigeration box 502 through the first conduit 511 and is cooled again; when the oil coolant is cooled, the servo motor 503 rotates, driving the main gear 504 and the first rotating shaft 506 to rotate , thereby causing the stirring blades 508 to stir the oil coolant in the refrigeration box 502, increasing the chance of it contacting the inner wall of the refrigeration box 502 to ensure that it is cooled down faster and participates in the subsequent oil coolant circulation cooling process; then, when the main gear 504 rotates, it will drive the slave gear 505 meshing with it to rotate, further causing the second rotating shaft 507 and the fan blades 509 thereon to rotate, so that the air in the fixed seat 4 is effectively circulated, thereby ensuring that the heat generated by the refrigeration box 502, the servo motor 503 and the circulating oil pump 510 during operation can be smoothly dissipated through the breathable net 501, avoiding high temperature from affecting the normal operation of electrical components.

[0049] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
