Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment, specifically a cylindrical metal part clamping and rotating device. Background Art

[0002] A chuck is an important accessory on a machine tool used for clamping and positioning workpieces. It typically consists of a chuck body, moving jaws, and a jaw drive mechanism. It utilizes the radial movement of the jaws to clamp and fix workpieces of different shapes and sizes, ensuring that the workpiece does not move or deform during machining. Chucks come in various types, including two-jaw, three-jaw, and four-jaw chucks, and different drive methods such as manual, pneumatic, and hydraulic. Among them, three-jaw chucks and four-jaw chucks are the most common, offering automatic centering and manual adjustment functions respectively, suitable for different machining needs.

[0003] Cylindrical workpieces are typically secured to machine tools using chucks for various machining operations. However, prolonged use leads to the gradual depletion of lubricating oil in the bearings inside the chuck. Bearings are crucial components of machinery, responsible for reducing friction and ensuring smooth operation. Because bearings are located inside the machine tool, lubricating them is relatively complex and inconvenient. Operators must disassemble certain machine tool parts to access the bearings and perform lubrication. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical metal part clamping and rotating device to solve the problem of easy bearing wear in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical metal part clamping and rotating device, comprising a device housing, a rotating chuck rotatably mounted on the device housing, a bearing seat fixedly mounted on the device housing, a bearing fixedly mounted inside the bearing seat, a lubrication mechanism connected to one side of the bearing seat, the lubrication mechanism comprising a sealing cover fixedly mounted on one side of the bearing seat and an oil storage tank fixedly mounted inside the device housing, a lubrication nozzle fixedly mounted inside the sealing cover, a lubrication oil pipe connected to the lubrication nozzle, an oil pump connected to the lubrication oil pipe, and a drive mechanism provided inside the device housing.

[0006] Preferably, the oil pump is connected to a drive shaft, the drive shaft is equipped with a planetary reducer, a return pipe is provided between the oil storage tank and the sealing cover, and the oil storage tank is connected to a refueling pipe.

[0007] Preferably, the bearing is mounted on the equipment housing via a bearing seat, and the sealing cover has an installation port, through which the lubrication nozzle is mounted on the sealing cover.

[0008] Preferably, one end of the return pipe is connected to the sealing cover, and the other end of the return pipe is connected to the oil storage tank; one end of the lubricating oil pipe is connected to the oil storage tank, and the other end of the lubricating oil pipe is connected to the sealing cover.

[0009] Preferably, the drive mechanism includes a drive motor fixedly installed inside the equipment housing and a movable shaft fixedly installed inside the bearing. A driven pulley is fixedly installed on the movable shaft. A drive shaft is fixedly installed at the output end of the drive motor. A drive pulley is fixedly installed on the drive shaft, and one end of the drive shaft is fixed at the middle position of the drive pulley. A drive belt is provided between the drive pulley and the driven pulley.

[0010] Preferably, bolts are provided at the four corners of the drive motor, and the drive motor is fixed to the equipment housing by the bolts.

[0011] Preferably, the driven pulley is movably mounted inside the equipment housing via a movable shaft, and the driving pulley is movably mounted inside the equipment housing via a drive shaft.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, the rotational motion of the transmission shaft is achieved by a motor drive mechanism. The rotational motion of the transmission shaft will cause the driving pulley to rotate accordingly. Then, through the transmission belt, the driven pulley will rotate accordingly. The rotation of the driven pulley will drive the movable shaft to rotate. During the rotation of the movable shaft, it will drive the cylindrical workpiece mounted on the rotary chuck to rotate synchronously, thereby facilitating efficient rotary machining of the workpiece.

[0014] 2. In this application, during the rotation of the drive shaft, its rotational power is transmitted to the transmission shaft, which in turn drives the oil pump. The operation of the oil pump delivers the lubricating oil in the oil reservoir to the lubrication nozzle. The lubricating oil is precisely sprayed onto the bearing surface through the nozzle to achieve lubrication of the bearing. This process is carried out when the rotating chuck is working, which can effectively slow down the wear rate of the bearing and thus extend the service life of the bearing.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a cylindrical metal part clamping and rotating device, including a device housing 1, a rotary chuck 2 rotatably mounted on the device housing 1, a bearing seat 3 fixedly mounted on the device housing 1, a bearing 4 fixedly mounted inside the bearing seat 3, a lubrication mechanism 5 connected to one side of the bearing seat 3, and a drive mechanism 6 provided inside the device housing 1. The drive mechanism 6 can drive the cylindrical workpiece on the rotary chuck 2 to rotate, facilitating the rotary processing of the cylindrical workpiece. The lubrication mechanism 5 can lubricate the bearing 4 when the rotary chuck 2 is rotating, reducing the wear rate of the bearing 4 and extending the service life of the bearing 4.

[0022] like Figure 2 and Figure 3 As shown, the lubrication mechanism 5 includes a sealing cover 501 fixedly installed on one side of the bearing seat 3 and an oil storage tank 509 fixedly installed inside the equipment housing 1. A lubrication nozzle 503 is fixedly installed inside the sealing cover 501. A lubrication oil pipe 502 is connected to the lubrication nozzle 503. An oil pump 505 is connected to the lubrication oil pipe 502. The bearing 4 is installed on the equipment housing 1 through the bearing seat 3. An installation port is opened on the sealing cover 501. The lubrication nozzle 503 is installed on the sealing cover 501 through the installation port. A planetary reducer 507 is provided on the drive shaft 506. A return pipe 504 is provided between the oil storage tank 509 and the sealing cover 501. The oil storage tank (509) is connected to a refueling pipe (508).

[0023] Specifically, during the rotation of the drive shaft 605, it drives the transmission shaft 506 to rotate as well. When the transmission shaft 506 rotates, it further drives the oil pump 505 to start operating. The operation of the oil pump 505 effectively extracts the lubricating oil from the oil reservoir 509. Subsequently, this lubricating oil is transported to the lubrication nozzle 503 through the pipeline system. When the lubricating oil reaches the lubrication nozzle 503, it is sprayed out and directly sprayed onto the surface of the bearing 4, ensuring that the bearing 4 receives continuous lubrication. In this way, the lubricating oil can reduce the friction and wear of the bearing 4 during operation, thereby effectively reducing the wear rate of the bearing 4. Ultimately, this continuous lubrication helps to extend the service life of the bearing 4 and ensures that the mechanical equipment can operate more stably and for longer.

[0024] like Figure 2 and Figure 4 As shown, the drive mechanism 6 includes a drive motor 604 fixedly installed inside the equipment housing 1 and a movable shaft 601 fixedly installed inside the bearing 4. A driven pulley 602 is fixedly installed on the movable shaft 601. A drive shaft 605 is fixedly installed at the output end of the drive motor 604. A drive pulley 606 is fixedly installed on the drive shaft 605, and one end of the transmission shaft 506 is fixed at the middle position of the drive pulley 606. A drive belt 603 is provided between the drive pulley 606 and the driven pulley 602. Bolts are provided at the four corners of the drive motor 604. The drive motor 604 is fixed inside the equipment housing 1 by bolts.

[0025] Specifically, the drive motor 604 drives the drive shaft 605 to rotate. When the drive shaft 605 starts to rotate, it will further drive the drive pulley 606 to rotate. During the rotation of the drive pulley 606, the drive pulley 606 will transmit power to the driven pulley 602 through the drive belt 603. After receiving the power, the driven pulley 602 will also start to rotate and will further drive the rotation of the movable shaft 601. During the rotation of the movable shaft 601, the cylindrical workpiece on the chuck will also start to rotate, which facilitates the rotational processing of the cylindrical workpiece.

[0026] Working principle: During use, the cylindrical workpiece is clamped by the rotary chuck 2. After the rotary chuck 2 clamps the cylindrical workpiece, the drive motor 604 can be started. The start of the drive motor 604 will drive the drive shaft 605 to rotate. The rotation of the drive shaft 605 will drive the drive pulley 606 to rotate. The rotation of the drive pulley 606 will drive the driven pulley 602 to rotate. The rotation of the driven pulley 602 will drive the movable shaft 601 to rotate. During the rotation of the movable shaft 601, the cylindrical workpiece on the rotary chuck 2 will rotate, which facilitates the rotation of the cylindrical workpiece. During the rotation of the rotary chuck 2, the drive shaft 605 will also drive the transmission shaft 506 to rotate. When the transmission shaft 506 rotates, it will drive the oil pump 505 to operate. During the operation of the oil pump 505, the lubricating oil in the oil storage tank 509 will be delivered to the lubrication nozzle 503. The lubricating oil delivered to the lubrication nozzle 503 will be sprayed onto the bearing 4, thereby lubricating the bearing 4 during the rotation of the rotary chuck 2, reducing the wear rate of the bearing 4, and extending the service life of the bearing 4. The excess lubricating oil sprayed out will flow back to the oil storage tank 509 through the return pipe 504 and after a series of circulation processes.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
