[0002] Laser engraving and cutting equipment is a widely used non-contact material removal processing equipment, which can complete the processing of workpieces of different materials and shapes. Among them, when it is necessary to accurately engrave and cut the surface of a workpiece with a circular or quasi-circular cross-section or a thin wall, it is essential to assist the positioning and clamping rotation of the rotary bearing device. The laser engraving and cutting equipment outputs a control signal to control the coordinated rotation of the rotary bearing device. In order to meet the positioning and fixing requirements of workpieces of different shapes and sizes of materials during the process of turning and cutting, a chuck or a bearing shaft is generally set to support the corresponding workpiece. However, the chuck and the bearing shaft of most existing laser engraving and cutting equipment cannot share a motor. Even if the chuck and the bearing shaft can share a motor, the chuck and the bearing shaft need to use tools to disassemble and assemble the chuck or the bearing when sharing the motor. In the process of disassembly and assembly with the help of tools, not only tools that match various parts are required, but also the disassembled parts need to be stored and sorted for the next use. The whole process is cumbersome and the disassembly and assembly efficiency is low. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] Combination Figures 1 to 7As shown, the bearing device body provided in this embodiment shares a driving assembly 210 through a chuck assembly 220 and a support shaft device 300, and the two cooperate with each other to carry parts of different specifications according to actual needs for subsequent processing. Specifically, the bearing device includes: a frame 100, a chuck device 200, a support shaft device 300 and a sensor assembly, the chuck device 200 includes a driving assembly 210 and a chuck assembly 220, the driving assembly 210 is rotatably arranged on the frame 100, and the chuck assembly 220 is transmission-connected to the first output shaft 211 of the driving assembly 210; the support shaft device 300 includes a clutch assembly 310 and a support shaft assembly 320, the second output shaft 212 of the driving assembly 210 is plugged into the input port 3101 on the clutch assembly 310, and is transmission-connected to the clutch assembly 310, and the support shaft assembly 320 is transmission-connected to the clutch assembly 310; the indicator can display the instantaneous state of the driving assembly 210.

[0038] Since the support shaft assembly 320 is connected to the clutch assembly 310 by transmission, and the second output shaft 212 is plugged with the input port 3101, the drive assembly 210 is connected to the clutch assembly 310 by transmission. Therefore, when installing the support shaft device 300, the support shaft device 300 is first placed on the frame 100, and then the input port 3101 is plugged with the second output shaft 212, so that the transmission connection between the drive assembly 210 and the support shaft device 300 can be achieved; when disassembling the support shaft device 300, it is only necessary to separate the input port 3101 and the second output shaft 212. In the whole process, while ensuring the use effect of the support shaft device 300 after installation, sharing one drive assembly 210 can realize two forms of power output, which can reduce the use cost; in addition, by cooperating with the second output shaft 212 and the clutch assembly 310, the convenience of the support shaft device 300 during installation or disassembly can be improved, and the steps of storing and arranging the disassembled parts during the disassembly process can be omitted, thereby improving the working efficiency of the bearing device.

[0039] In order to further facilitate the operator to accurately grasp the current position of the drive assembly 210, a sensor for sensing the position change of the drive assembly 210 can be set on the drive assembly 210. Therefore, when the position of the drive assembly 210 changes during the operation of the carrier device, the sensor accurately captures the current position of the drive assembly 210 and transmits the current position of the drive assembly 210 to the indicator in the form of a position signal. The indicator displays the current position of the drive assembly 210. The operator can accurately grasp the current position of the drive assembly 210 by observing the indicator. This can reduce the probability of errors in subsequent processing when cooperating with other mechanisms, so as to improve the processing effect of the workpiece on the carrier device.

[0040] In addition, in this embodiment, the first output shaft 211 and the second output shaft 212 can be configured to rotate simultaneously, or one of the output shafts can be configured to rotate according to actual needs.

[0041] Specifically, when the indicator is set as a dial indicator 10, the position change of the drive assembly 210 is reflected in the form of an angle on the dial indicator 10, and the operator can accurately grasp the specific position change of the drive assembly 210 by observing the angle of the dial indicator 10. When the indicator is set as a light indicator, the position change of the drive assembly 210 is reflected by the light change of the light indicator; specifically, when the drive assembly 210 is in the original state, the light indicator emits a green light, and when the drive assembly 210 rotates 90° or 180°, the light indicator emits a yellow light or a red light. When the indicator is set as a sound effect indicator, the position change of the drive assembly 210 is reflected by the sound effect indicator emitting different sound effects; specifically, when the drive assembly 210 is in the original state, the sound effect indicator directly reports the rotation angle of the drive assembly 210. The above indicators can be set separately or in combination with each other, and the specific display of each indicator shall be subject to actual production requirements. In this embodiment, the indicator is set as a dial indicator 10, and the dial is set as a transparent dial.

[0042] Preferably, the clutch assembly 310 includes an input shaft 311, a transmission shaft 312 and a support housing 313. The input shaft 311 and the transmission shaft 312 are both movably connected to the support housing 313. The first end of the input shaft 311 is provided with an input port 3101, which is plugged into the second output shaft 212. The support shaft assembly 320 is transmission-connected to the input shaft 311 through the transmission shaft 312. The support housing 313 supports the input shaft 311 and the transmission shaft 312, ensuring the normal use of the input shaft 311 and the transmission shaft 312 when they are arranged in the support shaft device 300; the input port 3101 on the input shaft 311 is transmission-connected to the second output shaft 212, and the transmission shaft 312 is transmission-connected to the input shaft 311, so as to drive the support shaft assembly 320 transmission-connected to the transmission shaft 312 to rotate, thereby realizing the installation of the support shaft device 300 and ensuring the use effect of the support shaft device 300 after installation.

[0043] Preferably, the clutch assembly 310 also includes a transmission belt 314, a plurality of transmission shafts 312 are provided, and the support shaft assembly 320 is provided with a plurality of bearing shafts 321 corresponding to the transmission shaft 312. The plurality of transmission shafts 312 are all connected to the second end of the input shaft 311 through the transmission belt 314, the first ends of the plurality of bearing shafts 321 are connected to the plurality of transmission shafts 312 one by one, and the second ends are all movably connected to the frame 100.

[0044] The number of transmission shafts 312 is appropriately increased or decreased according to actual production. In this embodiment, four transmission shafts 312 are provided, and the support shaft assembly 320 includes two bearing shafts 321 and two connecting members 322. The four transmission shafts 312 are evenly spaced along the width direction of the support shell 313; the first ends of the four transmission shafts 312 are transmission-connected to the second end of the input shaft 311 through the transmission belt 314, and the first ends of the two bearing shafts 321 are respectively transmission-connected to the two transmission shafts 312 therein, and the second ends of the two bearing shafts 321 are rotationally connected to the two connecting members 322 in a one-to-one correspondence. When the input port 3101 is plugged with the second output shaft 212, the two connecting members 322 are detachably connected to the frame 100, so that the support shaft device 300 can be installed on the frame 100 and transmission-connected to the drive assembly 210; at the same time, by providing the connecting member 322, the flexibility, connection strength and connection stability of the support shaft device 300 when installed on the frame 100 can be improved. In addition, since the first ends of the four transmission shafts 312 are all connected to the second end of the input shaft 311 through the transmission belt 314, when the support shaft device 300 is connected to the driving assembly 210, the driving assembly 210 drives the chuck assembly 220 to rotate, and can also drive the four transmission shafts 312 to rotate at the same time. When the first ends of the two bearing shafts 321 are respectively set to any two transmission shafts 312, the technical effect of carrying the corresponding workpiece for processing can be achieved. And by the first ends of the two bearing shafts 321 being respectively set to any two transmission shafts 312, the distance between the two bearing shafts 321 can be changed according to actual needs to carry workpieces of different diameters for processing, thereby improving the application range of the support shaft device 300 and the bearing device.

[0045] In addition, the cross-sectional shape of the input port 3101 is set to be an ellipse, a trapezoid or a polygon, and the cross-sectional shape of the end of the second output shaft 212 away from the driving component 210 is set to correspond to the cross-sectional shape of the input port 3101, so as to avoid the second output shaft 212 and the input shaft 311 from rotating relative to each other during the process of the driving component 210 driving the input shaft 311 to rotate.

[0046] In the optional technical solution of this embodiment, the clutch assembly 310 also includes an elastic member (not shown in the figure), which is arranged between the input port 3101 and the second output shaft 212. When the drive assembly 210 is in operation, a certain position change may occur. When the drive assembly 210 drives the input shaft 311 to rotate, the elastic member can offset a certain amount of position change of the drive assembly 210, thereby reducing the probability that the drive assembly 210 drives the input shaft 311 to produce a position change, so as to improve the bearing effect of the support shaft device 300. In addition, in order to further improve the use stability of the support shaft device 300, an elastic member can also be arranged between the transmission shaft 312 and the bearing shaft 321.

[0047] In this embodiment, in order to further improve the connection strength and connection stability when the support shaft device 300 is installed on the frame 100, the clutch assembly 310 also includes a limit member 315, which is arranged on the support shell 313 and cooperates with the frame 100 to limit the position. When the support shaft device 300 is installed on the frame 100, the limit member 315 is inserted into the frame 100 to limit the relative position of the support shaft device 300 and the frame 100 in the width direction of the frame 100.

[0048] In the optional technical solution of this embodiment, the frame 100 includes a base 110 and a support frame 120, the support frame 120 is arranged at the first end of the base 110, the driving assembly 210 is rotatably connected to the support frame 120, and the support shaft device 300 is arranged on the base 110 and is limitedly matched with the support frame 120.

[0049] Specifically, the support frame 120 is composed of two support plates, which are relatively spaced and arranged at the first end of the base 110, and the driving assembly 210 is rotatably connected between the two support plates to Figure 1 When rotating in the direction indicated by the middle arrow, interference with the base 110 is avoided to ensure the use effect of the driving assembly 210. The limiter 315 is inserted between the two support plates to limit the relative position of the support shaft device 300 and the frame 100 in the width direction of the frame 100.

[0050] In addition, since the driving assembly 210 is rotatably connected to the two support plates, when the diameter of the workpiece to be held by the chuck assembly 220 is small, the rotation angle of the driving assembly 210 is set to 0°, such as Figure 1 As shown; when the chuck assembly 220 needs to hold a workpiece with a larger diameter, the rotation angle of the drive assembly 210 is set to 180°, so that the chuck assembly 220 can avoid the base 110, avoiding interference between the chuck assembly 220 and the base 110 or the support shaft device 300 when holding a large diameter workpiece, thereby improving the application range of the chuck assembly 220 and the supporting equipment.

[0051] Furthermore, the chuck assembly 220 includes a connection seat 221 and a plurality of chucks 222, the connection seat 221 is transmission-connected to the first output shaft 211, and the plurality of chucks 222 are detachably connected to the connection seat 221. The chuck is transmission-connected to the first output shaft 211, and when the driving assembly 210 is in operation, the plurality of chucks 222 can be driven to rotate around the axis of the first output shaft 211, so as to realize processing of the workpiece clamped by the chuck assembly 220. At the same time, during the operation of the chuck, the chucks 222 in a stepped, rod-shaped or flat-plate shape can be replaced according to actual needs, so that the chuck assembly 220 can hold workpieces of different shapes, further improving the scope of application of the chuck assembly 220 and the carrying device.

[0052] Specifically, Figure 3 The figure shows an embodiment of supporting parts by the support shaft device 300. Figure 5 The embodiment shown is that the chuck assembly 220 cooperates with the buttstock assembly 400 to support the components. Figure 6 This is an implementation method in which the chuck assembly 220 clamps the component by means of a clamping needle. Figure 7 This is an embodiment in which the chuck assembly 220 clamps the component by means of a trapezoidal collet.

[0053] In the optional technical solution of this embodiment, the carrying device also includes a tail stock assembly 400, which is arranged on one side of the frame 100, and cooperates with the chuck assembly 220 or the support shaft assembly 320 to support the workpiece to be processed, and cooperates with the chuck assembly 220 or the support shaft device 300 to further improve the support effect of the workpiece to be processed. Since the tail stock assembly 400 is not connected to the base 110, when the rotation angle of the driving assembly 210 is 0°, the tail stock assembly 400 is placed at the second end of the base 110 to support the workpiece to be processed; when the rotation angle of the driving assembly 210 is 180°, the tail stock assembly 400 is placed at one end away from the second end of the base 110 to support the workpiece to be processed. In addition, the height of the tail stock assembly 400 can also be changed to support workpieces of different diameters to be processed. Specifically, the tail stock assembly 400 includes a bracket 410 and a support rod 420, and the bracket 410 is movably connected to the support rod 420 along the height direction of the support rod 420. By changing the relative position of the bracket 410 and the support rod 420, the actual height of the bracket 410 is changed, so as to achieve the technical purpose of supporting workpieces to be processed with different diameters. In addition, a limiter 315 is provided between the bracket 410 and the support rod 420, specifically, a sliding groove is provided on the support rod 420 along the height direction of the support rod 420, and the first end of the bracket 410 is slidably connected to the sliding groove; along the extension direction of the sliding groove, a plurality of limit through holes are provided on the sliding groove, and a limit hole is provided at the first end of the bracket 410. When the bracket 410 is adjusted to the target position, a limit pin is inserted between the corresponding limit through hole and the limit hole to limit the current position of the bracket 410 and the support rod 420. In addition, since the support wheel 411 is movably provided on the bracket 410, during the operation of the carrying device, the support wheel 411 can prevent the workpiece to be processed from directly contacting the bracket 410, so as to reduce the probability of the tail support assembly 400 causing damage to the workpiece.

[0054] In some other embodiments, the support rod 420 may be configured as a retractable rod. Alternatively, the relative position between the support rod 420 and the support rod 420 may be limited by tightening the support rod 410 with a screw. Alternatively, a power assembly connected to the support rod 410 may be configured to automatically change the relative position between the support rod 420 and the support rod 420.

[0055] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
