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.

[0028] See also Figure 1-3 The utility model provides a technical solution: a multi-station driving structure for a precision engraving machine, comprising a bracket 1, three through holes 2 are opened on the surface of the bracket 1, a transmission assembly 3 is inserted into the inner cavity of each through hole 2, a carrying plate 4 is provided at the bottom of the bracket 1, a power assembly 5 is provided on one side of the top surface of the carrying plate 4, and the output end of the power assembly 5 is meshed and connected with the bottom end of the transmission assembly 3; a base 6 is provided below the carrying plate 4, a pushing assembly 7 is provided on the top surface of the base 6 and in the middle position, and the telescopic end of the pushing assembly 7 is connected to the bottom surface of the carrying plate 4; slide rails 8 are provided on the top surface of the base 6 and on both sides of the pushing assembly 7, and sliders 9 for sliding on the slide rails 8 are provided on both sides of the bottom surface of the carrying plate 4;

[0029] The supporting plate 4 can provide stable support for the bracket 1 and the power component 5, and can slide on the two slide rails 8 on the base 6 through the two sliders 9. Since a pushing component 7 is provided on the top surface of the base 6 and in the middle position, and the telescopic end of the pushing component 7 is connected to the bottom surface of the supporting plate 4, the supporting plate 4 can be driven to slide back and forth by the telescopic movement of the pushing component 7, and thus the position of the bracket 1 can be adjusted. Since a transmission component 3 is installed in each of the three through holes 2 on the surface of the bracket 1, and the output end of the power component 5 is engaged and connected with the bottom end of each transmission component 3, the three transmission components 3 can be driven to run synchronously by the drive of the power component 5, and thus the workpiece clamping structure installed on the transmission component 3 can be driven synchronously to facilitate the rotation and feeding of the workpiece clamping structure. The three transmission components 3 driven by one power component 5 can not only drive multiple workstations to run simultaneously, but also save corresponding equipment components, thereby reducing equipment costs.

[0030] See Figure 3 、 Figure 4The transmission assembly 3 includes a stabilizing frame 31 arranged on the top surface of the bracket 1 and directly above the through hole 2. The inner cavity of the stabilizing frame 31 is fixedly provided with a hollow tube 32, and the top and bottom of the inner cavity of the hollow tube 32 are provided with ball bearings 33. The inner cavity of the ball bearing 33 is plugged with a shaft 34, and the bottom end of the shaft 34 passes through the through hole 2 and extends to the bottom of the bracket 1; the bottom end of the shaft 34 is connected to an outer gear ring 35 for engaging the output end of the power assembly 5, and the top of the shaft 34 is fixedly provided with a stud 36, and a positioning nut 37 is rotatably connected to the stud 36. Positioning holes 38 are opened at the four corners of the top surface of the stabilizing frame 31, and a positioning screw 39 is inserted into the inner cavity of each positioning hole 38, and the bottom end of the positioning screw 39 is connected to the top surface of the bracket 1;

[0031] Through the stabilizing frame 31 in the transmission assembly 3, it can be installed at the through hole 2 on the bracket 1 through the positioning hole 38 and the positioning screw 39, and the shaft 34 can be installed through two ball bearings 33, so that the shaft 34 can rotate flexibly. Since the bottom end of the shaft 34 is connected to the outer ring gear 35 for engaging the output end of the power assembly 5, when the power assembly 5 is running, the shaft 34 can be synchronously driven to rotate through the outer ring gear 35. The stud 36 at the top of the shaft 34 can be matched with the positioning nut 37, so that the workpiece clamping structure can be easily installed and fixed, and the shaft 34 can synchronously drive the workpiece clamping structure to rotate when it rotates.

[0032] See Figure 3 、 Figure 4 The inner diameter of the through hole 2 and the outer diameter of the shaft 34 can prevent the through hole 2 from affecting the rotation of the shaft 34.

[0033] See Figure 4 、 Figure 5 The power assembly 5 includes a worm 51 meshing with the outer gear ring 35. A seat bearing 52 is provided on the worm 51 near both ends. The bottom ends of the two seat bearings 52 are connected to the top surface of the carrier plate 4. One end of the worm 51 is connected to a forward and reverse motor 53, and the bottom surface of the forward and reverse motor 53 is connected to the top surface of the carrier plate 4.

[0034] The worm 51 in the power assembly 5 can be installed on the top surface of the supporting plate 4 through two seat bearings 52, and can be rotated smoothly under the drive of the forward and reverse motors 53, so that the worm 51 can synchronously drive the outer ring gear 35 to rotate while rotating, so as to drive the shaft 34 to rotate.

[0035] See Figure 3 、 Figure 6The pushing assembly 7 includes an electric push rod 71, a fixing seat 72 is provided in the middle of the electric push rod 71, and the bottom end of the fixing seat 72 is connected to the top surface of the base 6; the telescopic end of the electric push rod 71 is connected to a push plate 73, and the top end of the push plate 73 is connected to the bottom surface of the bearing plate 4;

[0036] By pushing the electric push rod 71 in the assembly 7, it can be fixed to the top surface of the base 6 through the fixing seat 72, and its telescopic end can be connected to the bottom surface of the supporting plate 4 through the push plate 73. Therefore, when the electric push rod 71 is extended or retracted, it can synchronously drive the supporting plate 4 to move forward and backward, thereby adjusting the position of the workpiece clamping structure installed on the transmission assembly 3.

[0037] See Figure 1 - Figure 3 A distance sensor 10 is provided on the top surface of the base 6 and between the two slide rails 8. A reflective plate 11 is provided on one side of the distance sensor 10, and the top end of the reflective plate 11 is connected to the bottom surface of the carrying plate 4;

[0038] The distance sensor 10 can cooperate with the reflector plate 11 to detect the position of the carrier plate 4 moving forward and backward, and the distance sensor 10 can send the monitoring data to the control center of the engraving machine, so that the carrier plate 4 can be accurately positioned, ensuring that the workpiece clamping structure can reach the specified position.

[0039] See Figure 3 The top view shape of the bracket 1 is the same as the top view shape of the carrying plate 4 , so that the carrying plate 4 can stably support the bracket 1 .

[0040] During operation, the supporting plate 4 can provide stable support for the bracket 1 and the power component 5, and can slide on the two slide rails 8 on the base 6 through the two sliders 9. Since a pushing component 7 is provided on the top surface of the base 6 and in the middle position, and the telescopic end of the pushing component 7 is connected to the bottom surface of the supporting plate 4, the supporting plate 4 can be driven to slide back and forth by the telescopic movement of the pushing component 7, and thus the position of the bracket 1 can be adjusted. Since a transmission component 3 is respectively installed in the three through holes 2 on the surface of the bracket 1, and the output end of the power component 5 is engaged and connected with the bottom end of each transmission component 3, the three transmission components 3 can be driven to run synchronously through the drive of the power component 5, and then the workpiece clamping structure installed on the transmission component 3 can be driven synchronously to facilitate the rotation and feeding of the workpiece clamping structure. The three transmission components 3 driven by one power component 5 can not only drive multiple workstations to run simultaneously, but also save corresponding equipment components, thereby reducing equipment costs.

[0041] Through the stabilizing frame 31 in the transmission assembly 3, it can be installed at the through hole 2 on the bracket 1 through the positioning hole 38 and the positioning screw 39, and the shaft 34 can be installed through two ball bearings 33, so that the shaft 34 can rotate flexibly. Since the bottom end of the shaft 34 is connected to the outer ring gear 35 for engaging the output end of the power assembly 5, when the power assembly 5 is running, the shaft 34 can be synchronously driven to rotate through the outer ring gear 35. The stud 36 at the top of the shaft 34 can be matched with the positioning nut 37, so that the workpiece clamping structure can be easily installed and fixed, and the shaft 34 can synchronously drive the workpiece clamping structure to rotate when it rotates.

[0042] The worm 51 in the power assembly 5 can be installed on the top surface of the supporting plate 4 through two seat bearings 52, and can rotate smoothly under the drive of the forward and reverse motors 53, so that the worm 51 can synchronously drive the outer gear ring 35 to rotate while rotating, so as to drive the shaft 34 to rotate. The electric push rod 71 in the pushing assembly 7 can be fixed to the top surface of the base 6 through the fixed seat 72, and its telescopic end can be connected to the bottom surface of the supporting plate 4 through the push plate 73. Therefore, when the electric push rod 71 is extended and retracted, it can synchronously drive the supporting plate 4 to move back and forth, thereby adjusting the position of the workpiece clamping structure installed on the transmission assembly 3. The distance sensor 10 can cooperate with the reflector plate 11 to detect the position of the supporting plate 4 moving back and forth, and the distance sensor 10 can send the monitoring data to the control center of the precision engraving machine, thereby accurately positioning the supporting plate 4, ensuring that the workpiece clamping structure can reach the specified position.

[0043] In summary, the device can not only drive multiple workstations to operate simultaneously, but also save corresponding equipment components, thereby reducing equipment costs.
