Description

Technical Field

[0001] The present application relates to the field of separation type processing equipment, and in particular to a separation type rotary drive device. Background Art

[0002] Cylindrical workpieces are a general term for circular workpieces with inner holes. Depending on their length and diameter, cylindrical workpieces are widely used in material transportation, storage containers, processing kilns, aerospace and other fields.

[0003] When machining the outer circle of a cylindrical workpiece, it is usually necessary to use an internal support fixture to clamp the cylindrical workpiece through the inner circle of the cylindrical workpiece, drive the cylindrical workpiece to rotate, and then use a machining head to perform corresponding machining on the outer circle surface of the cylindrical workpiece, such as turning, grinding or spraying. When machining the outer circle of a cylindrical workpiece with a long length, the device for clamping and rotating the cylindrical workpiece is usually set separately from the device for machining the outer circle of the cylindrical workpiece.

[0004] Existing devices for clamping and rotating cylindrical workpieces usually use a spindle head to clamp one end of the cylindrical workpiece, and a tailstock arranged opposite to the spindle head to clamp the other end of the cylindrical workpiece, and the spindle head drives the cylindrical workpiece to form a rotational motion. This requires that the clamping process of the cylindrical workpiece be carried out at a processing station. The clamping operation is limited by the space of the processing station, which affects the smooth clamping of large-diameter and large-mass cylindrical workpieces. Moreover, the clamping time of large-diameter and large-mass cylindrical workpieces is usually long. Once the spindle head is accidentally started during the clamping process, it will cause great safety risks. Utility Model Content

It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] An embodiment of the separate rotary drive device of the present application is as follows: Figures 1 to 3 As shown, it includes a rotary drive mechanism 1, a detachable drive head 2 and a coupling drive mechanism 3. The rotary drive mechanism 1 is used to generate a rotary motion, forming a power source for driving a cylindrical workpiece clamped on an external workpiece clamping device to rotate. The detachable drive head 2 is connected to the rotary drive mechanism 1, and can be combined with a drive coupling structure provided on the external workpiece clamping device, and is used to transmit the rotary drive force formed by the rotary drive mechanism 1 to the drive coupling structure, driving the cylindrical workpiece clamped on the workpiece clamping device to rotate. The coupling drive mechanism 3 is used to drive the detachable drive head 2 to move, forming a connection or separation with the external drive coupling structure.

[0039] The rotary drive mechanism 1 includes a rotary drive 11 and a rotary drive shaft 12. The rotary drive 11 can use various drive devices capable of generating rotary motion, such as an electric motor, an internal combustion engine, or a hydraulic motor, etc. In this embodiment, an electric motor is used. The rotary drive 11 and the rotary drive shaft 12 can be driven and connected in different ways such as a transmission belt, a transmission shaft, or a gear. In this embodiment, a belt and a pulley are used to drive and connect.

[0040] The detachable drive head 2 includes a drive disk 21 and a plurality of sliding support blocks 22. The center of the drive disk 21 is fixed to the end of the rotating drive shaft 12, and can rotate synchronously with the rotating drive shaft 12. The plurality of sliding support blocks 22 are respectively installed at different positions in the circumferential direction of the drive disk 21, and can slide on the drive disk 21. The connection between the detachable drive head 2 and the external drive connection structure is formed by the sliding support blocks 22 abutting against the inner wall of the cylindrical matching hole on the external drive connection structure; and when the sliding support blocks 22 leave the inner wall of the cylindrical matching hole, the detachable drive head 2 can be separated from the external drive connection structure.

[0041] The coupling drive mechanism 3 includes a coupling drive assembly 31, a mobile slip ring 32 and a plurality of sliding struts 33. The coupling drive assembly 31 can be any suitable mechanical combination structure with a driving source. The mobile slip ring 32 is sleeved on the rotating drive shaft 12. The coupling drive assembly 31 is connected to the mobile slip ring 32 and can drive the mobile slip ring 32 to slide axially on the rotating drive shaft 12. A plurality of sliding struts 33 are hinged at different positions on the circumference of one end of the mobile slip ring 32, and the other end of each sliding strut 33 is hinged to a sliding support block 22 respectively.

[0042] When the movable slip ring 32 slides axially on the rotating drive shaft 12 under the drive of the connecting drive assembly 31, it drives one end of multiple sliding struts 33 to move synchronously, thereby driving multiple sliding support blocks 22 to slide synchronously on the driving disk 21 through the other end of the sliding struts 33, forming a connection or separation with the external driving connecting structure.

[0043] The separate rotary drive device of the present application can not only rotationally drive the cylindrical workpiece clamped on the external workpiece clamping device, but can also be used to drive various other suitable rotary devices to form rotary motion, as long as the external rotary device is equipped with a driving connection structure with a cylindrical matching hole.

[0044] In some embodiments of the separate rotary drive device of the present application, Figures 1 to 3 As shown, three radial grooves 211 are arranged on the driving disk 21, and the three radial grooves 211 are evenly arranged on the driving disk 21, extending from the circumferential side edge of the driving disk 21 to the center direction. Side grooves 221 are arranged in the middle of both sides of the sliding support block 22, and the side grooves 221 penetrate the inner and outer edges of the sliding support block 22. The three sliding support blocks 22 are respectively installed on the driving disk 21 through the cooperation of the side grooves 221 and the radial grooves 211, so that each sliding support block 22 is located in a radial groove 211, and the side edges of the radial grooves 211 are engaged in the side grooves 221, so that each sliding support block 22 can slide in the corresponding radial groove 211 along the radial direction of the driving disk 21. When the sliding support block 22 slides in the circumferential direction of the driving disk 21, the outer side surface of the sliding support block 22 protrudes from the circumferential surface of the driving disk 21, and abuts against the side wall of the cylindrical matching hole on the external driving connection structure, forming a connection with the driving connection structure; when the sliding support block 22 slides in the center direction of the driving disk 21, the outer side surface of the sliding support block 22 is located on the inner side of the circumferential surface of the driving disk 21, and is separated from the driving connection structure.

[0045] In a preferred embodiment of the separate rotary drive device of the present application, as Figure 2 and Figure 3As shown, a hinge groove 222 parallel to the rotation axis direction of the driving disk 21 is provided on the inner side surface of the sliding support block 22, one end of the sliding support rod 33 extends into the hinge groove 222, and is connected to the two side walls of the hinge groove 222 through the hinge axis, and is hinged to the sliding support block 22 inside the hinge groove 222. This can not only prevent the sliding support rod 33 from interfering with the sliding support block 22 when rotating around the hinge axis, but also reduce the space occupied by the hinge structure.

[0046] In some embodiments of the separate rotary drive device of the present application, Figure 2 and Figure 3 As shown, three hinge brackets 321 are arranged at one end of the movable slip ring 32 adjacent to the driving disk 21, and the three hinge brackets 321 are evenly arranged on the outer circumference of the movable slip ring 32. The other end of the sliding support rod 33 is hinged to the hinge bracket 321 through a hinge shaft.

[0047] A specific articulated bracket 321 is two articulated plates fixed at intervals on the outer circumference of the movable slip ring 32. The end of the sliding strut 33 is arranged between the two articulated plates. The articulated shaft passes through the end of the sliding strut 33 and is connected to the articulated plates on both sides to form an articulation between the sliding strut 33 and the movable slip ring 32.

[0048] In some embodiments of the separate rotary drive device of the present application, Figure 1 and Figure 2 As shown, the separate rotary drive device of the present application is also provided with a mounting frame 4, which is a metal bracket used to install and position other structures in the separate rotary drive device of the present application, and the rotary drive mechanism 1, the detachable drive head 2 and the connecting drive mechanism 3 are all directly or indirectly mounted on the mounting frame 4.

[0049] Specifically, the rotating drive shaft 12 is installed on the top of the mounting frame 4 through a bearing, so that the rotating drive shaft 12 can rotate on the mounting frame 4; the rotating driver 11 is fixed on the partition inside the mounting frame 4, and a rotating drive wheel is arranged on the output shaft of the rotating driver 11, and a rotating driven wheel is arranged at the end of the rotating drive shaft 12 opposite to the driving disk 21, and the rotating drive wheel and the rotating driven wheel are connected by a transmission belt. When the rotating driver 11 is working, the rotating drive shaft 12 is driven to rotate on the mounting frame 4 through the transmission belt, thereby driving the driving disk 4 to rotate.

[0050] In a preferred embodiment of the separate rotary drive device of the present application, as Figure 2 and Figure 3 As shown, a shift fork sliding groove 322 is provided on the end of the outer circumferential surface of the movable slip ring 32 away from the driving disc 21 , and the shift fork sliding groove 322 extends in the radial direction of the movable slip ring 32 .

[0051] The coupling drive assembly 31 includes a coupling drive 311 and a slip ring fork 312. The coupling drive 311 can be any driving device capable of linear driving, such as a cylinder, a hydraulic cylinder, an electric push rod, etc. The coupling drive 311 is fixed on the mounting frame 4, below the rotating drive shaft 12. The slip ring fork 312 is a rod-shaped structure with a fork tine at one end, and the middle part of the slip ring fork 312 is hinged on the mounting frame 4, so that the slip ring fork 312 can rotate relative to the mounting frame 4. The fork rod at one end of the slip ring fork 312 is hinged to the output shaft of the coupling drive 311 (a piston rod when the coupling drive 311 is a cylinder or a hydraulic cylinder), and the fork tine at the other end is engaged with the fork slide groove 322. When the output shaft of the coupling driver 311 extends outward, the fork rod of the slip ring fork 312 is pushed to move outward, so that the fork teeth of the slip ring fork 312 move in the direction close to the mounting frame 4, and the fork teeth push the movable slip ring 32 to slide in the direction away from the driving disk 21 through the fork slot 322, and the sliding support block 22 is pulled to slide toward the inside of the driving disk 21 through the sliding support rod 33, so that the detachable driving head 2 is separated from the driving coupling structure; when the output shaft of the coupling driver 311 is retracted inward, the fork rod of the traction slip ring fork 312 is moved inward, so that the fork teeth of the slip ring fork 312 move in the direction away from the mounting frame 4, and the fork teeth push the movable slip ring 32 to slide in the direction of the driving disk 21 through the fork slot 322, and the sliding support block 22 is pushed to slide toward the outer periphery of the driving disk 21 through the sliding support rod 33, so that the detachable driving head 2 is connected to the driving coupling structure.

[0052] As a specific implementation of the separate rotary drive device of the present application, Figure 3 As shown, a roller shaft is fixedly arranged inside the fork teeth of the slip ring fork 312, and the fork tooth roller 3121 is installed on the roller shaft through a bearing and can rotate on the roller shaft. The fork teeth of the slip ring fork 312 are arranged on the outside of the fork slide groove 322, so that the fork tooth roller 3121 is engaged in the fork slide groove 322. When the slip ring fork 312 rotates under the drive of the coupling driver 311, the fork tooth roller 3121 contacts the side wall of the fork slide groove 322, pushing the mobile slip ring 32 to slide on the rotating drive shaft 12. While the fork tooth roller 3121 applies a driving force to the side wall of the fork slide groove 322, the fork tooth roller 3121 can roll on the side wall of the fork slide groove 322 to reduce the friction between the two.

[0053] In some embodiments of the separate rotary drive device of the present application, Figure 1 and Figure 2As shown, the separate rotary drive device of the present application is further provided with a mounting base 5, which includes a mounting base bottom plate 51, a movable mounting plate 52 and a mounting plate pushing device 53.

[0054] The mounting plate pushing device 53 can use various driving devices that can push the movable mounting plate 52 to move, such as a driving device that directly generates a linear driving force, such as a hydraulic cylinder, a pneumatic cylinder, or a device that generates a linear driving force by rotating a driving device, such as a ball screw, a propulsion screw, etc. The mounting plate pushing device 53 is disposed between the mounting seat bottom plate 51 and the movable mounting plate 52, and can drive the movable mounting plate 52 to slide on the mounting seat bottom plate 51.

[0055] The mounting frame 4 is fixedly mounted on the movable mounting plate 52, and can slide on the mounting seat bottom plate 51 along the direction of the rotating drive shaft 12 together with the movable mounting plate 52. When the movable mounting plate 52 moves toward the end of the rotating drive shaft 12 where the driving disk 21 is located, the driving disk 21 can approach the external driving connection structure and extend into the cylindrical matching hole, so as to form a connection with the external driving connection structure; when the movable mounting plate 52 moves toward the end of the rotating drive shaft 12 away from the driving disk 21, the driving disk 21 can leave the cylindrical matching hole and separate from the external driving connection structure.

[0056] A plurality of mounting grooves extending in a direction perpendicular to the rotating drive shaft 12 can also be provided at the bottom of the mounting frame 4, and the mounting frame 4 can be fixed to the movable mounting plate 52 by means of mounting bolts passing through the mounting grooves. By adjusting the fixed position of the mounting bolts in the mounting grooves, the lateral position of the mounting frame 4 on the movable mounting plate 52 can also be adjusted, so as to facilitate a better coaxial connection between the detachable drive head 2 and the external drive connection structure.

[0057] In a preferred embodiment of the separate rotary drive device of the present application, as Figure 1 and Figure 2 As shown, two parallel movable rails 511 are arranged on both sides of the top surface of the mounting base bottom plate 51, and two sliders 521 are arranged at corresponding positions on both sides of the bottom surface of the movable mounting plate 52.

[0058] The mounting plate pushing device 53 uses a pushing cylinder, the cylinder body at one end of the pushing cylinder is hinged to the mounting base 5, and the piston rod of the pushing cylinder is hinged to the movable mounting plate 52. The hinged connection method can reduce the installation accuracy requirements of the pushing cylinder and prevent the pushing cylinder from being stuck due to the lateral force during operation.

[0059] As a specific implementation of the separate rotary drive device of the present application, Figure 1 and Figure 2 As shown, the mounting base 5 also includes a height adjustment plate 54. A height adjustment member 522 is provided on the movable mounting plate 52, and the height adjustment member 522 can be various devices capable of manually or automatically adjusting the mounting height, such as a hydraulic lifting rod, an electric lifting rod, an adjusting bolt, etc. The height adjustment member 522 is mounted and fixed on the movable mounting plate 52, and the height adjustment plate 54 is mounted on the adjusting end of the height adjustment member 522. By adjusting the height adjustment member 522, such as adjusting the nut position on the bolt, the installation height of the height adjustment plate 54 on the movable mounting plate 52 is adjusted.

[0060] The mounting frame 4 is mounted on the height adjustment plate 54, and under the adjustment of the height adjustment member 522, the height of the mounting frame 4 changes along with the height adjustment plate 54. In this way, the height adjustment member 522 can adjust the height of the detachable drive head 2 mounted on the mounting frame 4, so that the rotation axis of the detachable drive head 2 and the rotation axis of the external drive coupling structure have the same height, which facilitates the connection between the detachable drive head 2 and the external drive coupling structure.
