Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing housing technology, specifically to an overheat-resistant split-type machine tool bearing housing. Background Technology
[0002] The function of a bearing housing is to provide support for both ends of a shaft. Bearings are housed within the housing, and the ends of the shaft are fixedly inserted into the bearings, allowing them to rotate under the bearing's force. Bearing housings come in two types: split and one-piece. Split bearing housings are more widely used.
[0003] Existing machine tool bearing housings are prone to overheating during use due to the high-speed rotation of the machine tool spindle over a long period of time. Once overheating occurs, it will cause instability of the bearing housing, which in turn will affect the normal operation of the bearing. In addition, split bearing housings generally rely on bolts to overcome longitudinal resistance. When the bolts loosen, the fasteners and mounting parts will become loose, resulting in reduced stability. To address this issue, we propose an overheat-resistant split machine tool bearing housing. Utility Model Content
[0004] The purpose of this utility model is to provide an overheat-resistant split-type machine tool bearing housing to solve the problem mentioned in the background art. During use, the machine tool spindle rotates at high speed for a long time, which makes the bearing housing and bearing prone to overheating. Once overheating occurs, it will lead to instability of the bearing housing, which in turn will affect the normal operation of the bearing. Furthermore, split-type bearing housings generally rely on bolts to overcome longitudinal resistance. When the bolts loosen, the fastener and the mounting part will become loose, resulting in reduced stability.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an overheat-resistant split-type machine tool bearing housing, comprising a lower bearing housing, an upper bearing housing, and a water tank. The upper bearing housing is screwed to the top of the lower bearing housing, and the water tank is fixedly connected to the bottom of the lower bearing housing. A first copper tube is provided inside the lower bearing housing, and the first copper tube is connected to the water tank through a pipe. A first heat-conducting plate is embedded in the inner sidewall of the lower bearing housing. A second copper tube is provided inside the upper bearing housing, and a second heat-conducting plate is embedded in the inner sidewall of the upper bearing housing. A water pump is fixedly connected to the left sidewall of the water tank, and the water pump is connected to the second copper tube through a pipe.
[0006] As a further description of the above technical solution:
[0007] The left and right side walls of the lower shaft seat are integrally formed with a first fixing plate, and the left and right side walls of the first fixing plate are provided with a first slot.
[0008] As a further description of the above technical solution:
[0009] The upper shaft seat has a second fixing plate integrally formed on its left and right side walls. The left and right side walls of the second fixing plate have a second slot. The inner cavity of the second slot and the first slot is fitted with a card plate. The top of the second fixing plate is screwed with a bolt.
[0010] As a further description of the above technical solution:
[0011] The front and rear side walls of the inner cavity of the water tank are inlaid with semiconductor cooling chips, and the front and rear side walls of the water tank are fixedly connected to a frame.
[0012] As a further description of the above technical solution:
[0013] A fan is fixedly connected to the front wall of the inner cavity of the frame, and a dustproof net is fixedly connected between the inner walls of the frame.
[0014] As a further description of the above technical solution:
[0015] A motor is fixedly connected to the middle of the right side wall of the water tank. A rotating shaft is fixedly connected to the end of the power output shaft of the motor. The end of the rotating shaft passes through the water tank and extends into the inner cavity of the water tank. A stirring rod is fixedly connected to the outer side wall of the rotating shaft, and the stirring rods are arranged sequentially from left to right.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This anti-overheating split-type machine tool bearing housing uses a water pump to deliver coolant from the water tank to the second copper pipe. The coolant absorbs heat from the upper bearing housing through the second heat-conducting plate. Then, the coolant flows into the first copper pipe to cool the lower bearing housing, thus preventing the bearing housing from overheating. The coolant that has absorbed heat then flows back to the water tank and is cooled by the cold end of the semiconductor cooling chip, keeping the coolant in the water tank at a low temperature. Finally, the motor drives the rotating shaft to rotate, causing the stirring rod to continuously agitate the coolant, ensuring that the coolant is evenly cooled by the semiconductor cooling chip. This gives the bearing housing an anti-overheating function and improves its performance.
[0018] 2. This overheat-resistant split-type machine tool bearing housing uses a clamping plate whose two ends are respectively inserted into the first and second clamping slots. This clamping plate fastens the first and second fixing plates together, allowing the clamping plate to share the force borne by the bolts during use, thus protecting the bolts. Furthermore, even if the bolts loosen, the clamping plate can still fasten the first and second fixing plates, thereby preventing the lower and upper bearing seats from loosening and improving the operational stability of the bearing housing.

[0027] This utility model provides an overheat-resistant split-type machine tool bearing housing, which has an overheat protection function, improves the performance of the bearing housing, and enhances the operational stability of the bearing housing. Please refer to [link / reference]. Figures 1-4 It includes a lower shaft seat 100, an upper shaft seat 200, and a water tank 300;
[0028] Please refer to it again. Figures 1-4 The upper shaft seat 200 is screwed to the top of the lower shaft seat 100, and the water tank 300 is fixedly connected to the bottom of the lower shaft seat 100. The lower shaft seat 100 has a first copper pipe 110 inside, which is connected to the water tank 300 via a pipe. A first heat-conducting plate 120 is embedded in the inner wall of the lower shaft seat 100. The upper shaft seat 200 has a second copper pipe 210 inside, and a second heat-conducting plate 220 is embedded in the inner wall of the upper shaft seat 200. The left side wall of the water tank 300 is fixedly connected to the lower shaft seat 100. A water pump 310 is fixedly connected, and the water pump 310 is connected to the second copper pipe 210 through a pipe. Semiconductor cooling chips 320 are embedded in the front and rear side walls of the inner cavity of the water tank 300. A frame 330 is fixedly connected to the front and rear side walls of the water tank 300. A fan 340 is fixedly connected to the front side wall of the inner cavity of the frame 330. A dustproof net 350 is fixedly connected between the inner side walls of the frame 330. A motor 360 is fixedly connected to the middle of the right side wall of the water tank 300. The motor 360 is powered by… A rotating shaft 370 is fixedly connected to the end of the output shaft. The end of the rotating shaft 370 passes through the water tank 300 and extends into the inner cavity of the water tank 300. A stirring rod 380 is fixedly connected to the outer wall of the rotating shaft 370, and the stirring rods 380 are arranged sequentially from left to right. The coolant in the water tank 300 is transported to the second copper pipe 210 by the water pump 310, so that the coolant absorbs the heat of the upper bearing seat 200 through the second heat conduction plate 220. Then the coolant flows into the first copper pipe 110, so that the coolant cools the lower bearing seat 100, thereby preventing the bearing seat from overheating. Then the coolant that has absorbed the heat flows back to the water tank 300 and is cooled by the cold end of the semiconductor cooling chip 320, so that the coolant in the water tank 300 is kept at a low temperature. Finally, the rotating shaft 370 is driven to rotate by the motor 360, so that the stirring rod 380 continuously stirs the coolant, thereby allowing the coolant to be cooled evenly by the semiconductor cooling chip 320.
[0029] In summary, this gives the bearing housing overheat protection function and improves the performance of the bearing housing.
[0030] Please see Figure 1 , Figure 2 and Figure 4 The lower shaft seat 100 has a first fixing plate 130 integrally formed on its left and right side walls. The left and right side walls of the first fixing plate 130 have first slots 140. The upper shaft seat 200 has a second fixing plate 230 integrally formed on its left and right side walls. The left and right side walls of the second fixing plate 230 have second slots 240. A retaining plate 250 is inserted into the inner cavity of the second slot 240 and the first slot 140. A bolt 260 is screwed to the top of the second fixing plate 230. By connecting the two ends of the retaining plate 250... The first retaining plate 250 is inserted into the first retaining plate 140 and the second retaining plate 240 respectively, so that the retaining plate 250 fastens the first fixing plate 130 and the second fixing plate 230 together. This allows the retaining plate 250 to share the force borne by the bolt 260 when the bearing seat is in use, thereby protecting the bolt 260. Furthermore, when the bolt 260 loosens, the retaining plate 250 can still fasten the first fixing plate 130 and the second fixing plate 230, thereby preventing the lower bearing seat 100 and the upper bearing seat 200 from loosening.
[0031] In summary, this improves the operational stability of the bearing housing.
[0032] In practical use, those skilled in the art first install the lower bearing seat 100 on the machine tool and align the upper bearing seat 200 with the lower bearing seat 100. Then, insert both ends of the clamping plate 250 into the first clamping slot 140 and the second clamping slot 240 respectively, so that the clamping plate 250 fastens the first fixing plate 130 and the second fixing plate 230 together. At this time, screw in the bolt 260, so that the bolt 260 locks the first fixing plate 130, the second fixing plate 230 and the clamping plate 250, thus completing the overall installation of the bearing seat. Afterwards, during the use of the bearing seat, the coolant in the water tank 300 is delivered to the second copper pipe 210 by the water pump 310, so that the coolant first energizes the upper bearing seat 200. The heat from the 00 is absorbed, and then the coolant flows into the first copper pipe 110, which cools the lower bearing 100. The coolant that has absorbed the heat flows back into the water tank 300. Then, by activating the semiconductor cooling chip 320, the cold end of the semiconductor cooling chip 320 is cooled. At the same time, the motor 360 drives the rotating shaft 370 to rotate, which causes the stirring rod 380 to continuously stir the coolant, so that the coolant can be evenly cooled by the semiconductor cooling chip 320. This keeps the coolant in the water tank 300 at a low temperature. Finally, the fan 340 dissipates heat from the hot end of the semiconductor cooling chip 320, so that the semiconductor cooling chip 320 can continue to work.
