The first connecting shaft 44 moves back and forth linearly and the angle formed by the extension direction of the first linear guide 42 and the horizontal direction of the first support member 3 is the first angle, so that the first support member 3 can swing relative to the base 2 around the axis direction of the first rotating shaft 31, that is, the bed board 7 is swung around the axis of the first rotating shaft 31.

[0060] like Figure 7 As shown, on the basis of the above embodiment, the second driving assembly 6 includes a third bearing seat 61, which is symmetrically fixed on the support frame 34; a third linear guide rail 62, which is symmetrically fixed on the inner wall of the second through groove 53 with a front-back tilt, and the angle formed by the extension direction of the third linear guide rail 62 and the horizontal direction of the second support member 5 is a second angle, and the second angle is an acute angle. More specifically, the angle range of the second angle is 10°-20°, and a third slider 621 is slidably provided on the third linear guide rail 62; a second lead screw 63, which is rotatably connected to the two third bearing seats 61, and a second nut seat 631 is provided on the second lead screw 63. A second connecting shaft 64 is fixed on the front and rear sides of the second nut seat 631. The second connecting shaft 64 is arranged parallel to the second rotating shaft 52. The ends of the two second connecting shafts 64 are rotatably connected to the second movable bearing seat 65. The second movable bearing seat 65 is fixedly connected to the third slider 621; the fourth linear guide rail 66 is symmetrically fixed on the support frame 34, and the two fourth linear guide rails 66 are both slidably provided with a fourth slider 661, and the two fourth sliders 661 are both fixedly connected to the second nut seat 631; the second motor 67 is fixed on the support frame 34, and the output end of the second motor 67 is transmission-connected to the input end of the second lead screw 63.

[0061] Among them, the second motor 67 can make the second screw 63 rotate relative to the third bearing seat 61, and the rotation of the second screw 63 can make the second nut seat 631 and the second connecting shaft 64 move back and forth on the fourth linear guide 66. The second connecting shaft 64 and the second movable bearing seat 65 constitute a rotating pair, and the second movable bearing seat 65 and the third slider 621 constitute a moving pair. The angle formed by the extension direction of the third linear guide 62 and the horizontal direction of the second support member 5 is the second angle, and then the reciprocating linear motion of the second connecting shaft 64 can make the second support member 5 swing around the axis direction of the second rotating shaft 52, that is, to realize the pitching motion of the bed board 7 around the axis of the second rotating shaft 52.

[0062] Specifically, the second screw 63 is a trapezoidal screw, the second motor 67 is a DC motor, the output shaft of the second motor 67 is provided with a synchronous pulley, and the end of the second screw 63 is provided with a synchronous pulley. The synchronous pulley of the second motor 67 and the synchronous pulley of the second screw 63 are connected by a synchronous belt to realize the transmission connection between the second motor 67 and the second screw 63. The transmission connection between the second motor 67 and the second screw 63 in this application can also be a chain drive, which can be selected according to actual needs.

[0063] Based on the above embodiment, the monitoring component includes a dual-axis inclination sensor 8, which is arranged on the second support member 5. The dual-axis inclination sensor 8 is used to monitor the inclination value of the bed board 7 in the first direction and the inclination value in the second direction, that is, the dual-axis inclination sensor 8 is used to monitor the axial swing angle of the bed board 7 around the first rotating shaft 31 and the axial pitch angle of the bed board 7 around the second rotating shaft 52, so that the control system can accurately control the swing and pitch movements of the bed board 7 according to the monitoring values ​​of the dual-axis inclination sensor 8.

[0064] Based on the above embodiment, the monitoring component also includes a first displacement sensor component and a second displacement sensor component. The first displacement sensor component is used to obtain the position value of the first connecting shaft 44 during linear motion, and the second displacement sensor component is used to obtain the position value of the second connecting shaft 64 during linear motion. The inclination angle value of the bed board 7 in the first direction and the position value of the first connecting shaft 44 during linear motion form a one-to-one mapping relationship, and the inclination angle value of the bed board 7 in the second direction and the position value of the second connecting shaft 64 during linear motion form a one-to-one mapping relationship. The first displacement sensor component includes a first angle encoder 81, which is provided on the base 2, and the rotating shaft of the first angle encoder 81 is rotatably connected to the output end of the first screw 43; the second displacement sensor component includes a second angle encoder 82, which is provided on the support frame 34, and the rotating shaft of the second angle encoder 82 is rotatably connected to the output end of the second screw 63.

[0065] The purpose of this setting is to verify whether the monitoring data of the dual-axis tilt sensor 8 is correct through the setting of the first angle encoder 81 and the second angle encoder 82, and then determine whether the bed board 7 has reached the specified position. Since the dual-axis tilt sensor 8 of this application has high measurement accuracy, the swing and pitch angle values ​​of the bed board 7 of this application are mainly based on the monitoring data of the dual-axis tilt sensor 8, and the first angle encoder 81 and the second angle encoder 82 of this application are direct uses of the existing technology. Therefore, this application does not elaborate on the working principles of the first angle encoder 81 and the second angle encoder 82 and their acquisition of position data.

[0066] Specifically, the rotating shaft of the first angle encoder 81 is rotatably connected to the output end of the first screw 43 as a belt connection, and the rotating shaft of the second angle encoder 82 is rotatably connected to the output end of the second screw 63 as a belt connection. This application not only protects the belt drive connection method, but also the chain drive.

[0067] Based on the above embodiment, the control system includes a host computer and a controller. The host computer establishes a signal connection with the controller and the monitoring component. The controller establishes a signal connection with the first drive component 4 and the second drive component 6 respectively. The purpose of this setting is to input instructions through the host computer, and the controller controls the first drive component 4 and the second drive component 6 to respectively control the swing motion and pitch motion of the bed board 7. The data monitored by the first angle encoder 81, the second angle encoder 82 and the dual-axis inclination sensor 8 are transmitted to the host computer. When the host computer determines that the bed board 7 has reached the specified position, the host computer controls the first drive component 4 and the second drive component 6 to stop working.

[0068] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The above examples are intended only to facilitate understanding of the treatment couch method and its core concept provided by the present invention.
