[0031] The following describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0032] A forming and polishing device for spherical and columnar stone handicrafts, referring to Figure 1 and Figure 2 , includes a support frame 100, a clamping module 10, a processing module, and a clamping module feeding device. A support plate 101 is provided on the support frame 100. The support plate 101 is divided into a clamping module loading station, several processing stations, and a loading and unloading station along the X-axis direction. A clamping module 10 is placed at each station. At least one model blank is installed in each clamping module 10. A processing module is provided on one side in the Y-axis direction of each processing station.

[0033] Referring to Figure 1 and Figure 2 , in this embodiment, the number of processing stations shown is eight, and the processing module includes three grinding and forming modules 20 and five polishing modules 30. The three grinding and forming modules 20 and the five polishing modules 30 are continuously arranged from front to back along the X-axis direction on the Y-axis side of the eight processing stations.

[0034] Referring to Figures 1 to 3 , the above-mentioned clamping module feeding device 40 is provided above the loading and unloading station. The clamping module feeding device 40 is used to clamp the clamping module 10 loaded with the model blank to be processed and send it to the clamping module loading station. The clamping module feeding device 40 includes a frame 41, a sliding plate 42, and a clamping manipulator 43. An X-axis slide rail 411 and an X-axis driving mechanism are installed on the frame 41. The sliding plate 42 is arranged on the X-axis slide rail 411 and is connected to the X-axis driving mechanism. The X-axis driving mechanism includes an X-axis driving motor 4121, a driving pulley 4122, a driven pulley 4123, and a belt 4124. The output shaft of the X-axis driving motor 4121 is connected to the driving pulley 4122. The driven pulley 4123 is installed on the frame 4121. The driving pulley 4122 and the driven pulley 4123 are connected by the belt 4124. The sliding plate 42 is connected to the belt 4124. The X-axis driving motor 4121 drives the driving pulley 4122 to rotate, and the belt 4124 is transmitted between the driving pulley 4122 and the driven pulley 4123, thereby pulling the sliding plate 42 to move on the X-axis slide rail 411.

[0035] Referring to Figures 1 to 3, the clamping manipulator 43 is installed below the sliding plate 42 through a Z-axis driving mechanism. The clamping manipulator includes a lifting plate 431, at least a pair of clamping jaws, and a clamping jaw driving mechanism 433 for driving the clamping jaws to open outwards or contract inwards. The clamping jaws are preferably two pairs, and each pair of clamping jaws includes two clamping jaws 432 symmetrically installed on both sides of the lifting plate in the Y-axis direction. A hinge seat 4311 is provided on each side of the lifting plate 431, and each clamping jaw 432 is hinged to the hinge seat 4311 through a pin shaft. The above-mentioned clamping jaw driving mechanism 433 is preferably a Z-axis driving cylinder, and the Z-axis driving cylinder is vertically installed on the lifting plate 431 through a cylinder mounting seat. The piston rod of the Z-axis driving cylinder is respectively connected to each clamping jaw 432 through a connecting rod 4331. When the Z-axis driving cylinder acts downward, one end of each connecting rod 4331 connected to the piston rod rotates downward respectively, and the other end of the connecting rod 4331 connected to the clamping jaw 432 swings upward, thereby pulling the clamping jaw 432 to swing upward, so that the clamping jaw 432 releases the clamping module; conversely, the clamping jaw clamps the clamping module.

[0036] Referring to Figure 3 , the above-mentioned Z-axis driving mechanism includes a reduction gear 441, a winding drum 442, a lifting rope 443, and a guide rod 444. The reduction gear 441 is fixed on the top surface of the sliding plate 42, and the output shaft of the reduction gear 441 is connected to a winding drum 442. A lifting rope 443 connected to the center of the lifting plate 431 is wound around the winding drum 442. A guide rod 444 is fixedly connected to the top surface of the lifting plate 431, and the upper part of the guide rod 444 passes through the sliding plate 42 correspondingly.

[0037] Referring to Figure 1 and Figure 4 , each of the above-mentioned clamping modules 10 includes an upper connecting plate 11, a lower connecting plate 12, and at least one set of clamping components for installing a model blank. In this embodiment, the number of clamping components shown is two sets. The upper connecting plate 11 and the lower connecting plate 12 are fixedly connected through a plurality of connecting columns 111. Each clamping component includes a clamping upper shaft 131 and a clamping lower shaft 132.

[0038] Referring to Figures 4 to 6, the above clamping upper shaft 131 is composed of a guide sleeve 1311, a guide bearing 1312, an upper pressure rod 1313 and a fastening screw 1314. The guide sleeve 1311 is fixedly installed on the upper connecting plate 11. The guide bearing 1312 is slidably installed in the guide sleeve 1311. The fastening screw 1314 is threadedly connected to the top of the guide sleeve 1311, and its bottom end is fixed at the top end of the guide bearing 1312. The upper pressure rod 1313 is installed in the guide bearing 1312, and its lower part passes out below the guide bearing 1312. The bottom end of the upper pressure rod 1313 abuts against the upper positioning hole at the top end of the model blank. By rotating the fastening screw, it moves downward to push the guide bearing downward so that the bottom end of the upper pressure rod abuts tightly against the upper positioning hole of the model blank. When disassembling, rotate the fastening screw in the reverse direction to make it move upward. Since there is a gap between the guide bearing and the fastening screw in the vertical direction, the guide bearing can be pushed upward to make the upper pressure rod leave the upper positioning hole of the model blank, and then the stone finished product can be taken out (the model blank forms the stone finished product after forming and polishing).

[0039] Referring to Figure 4 and Figure 7 , the clamping lower shaft 132 includes a lower bearing 1321 fixed to the lower connecting plate and a lower pressure rod 1322 fixedly penetrating through the inner ring of the lower bearing. The top end of the lower pressure rod 1322 abuts against the lower positioning hole at the top end of the model blank, and a driven wheel 1323 is coaxially connected to the bottom of the lower pressure rod 1322.

[0040] Referring to Figure 1 and Figure 8 , on the other side in the Y-axis direction of each of the above processing stations, a rotary drive device is respectively provided. The rotary drive device includes a rotary drive motor 141, a driving wheel 142, a motor mounting plate 143, a Y-axis slide rail 144 and a Y-axis drive cylinder 145.

A friction wheel 121 is further installed on the top surface of each of the lower connecting plates 12, and a transition wheel (not shown in the figure) coaxially connected to the friction wheel 121 is installed on the bottom surface of the lower connecting plate 12. The transition wheel and the driven wheel 1323 are connected by a second belt 1324. When the clamping module is pushed to the corresponding processing station and positioned, the Y-axis drive cylinder 145 pushes the motor mounting plate 143 to slide along the Y-axis slide rail 144, so that the driving wheel 142 contacts the friction wheel 121. The rotary drive motor 141 works to make the driving wheel 142 rotate. Through the friction effect, the friction wheel 121 rotates, and then drives the transition wheel below it to rotate. Under the action of the second belt 1324, the driven wheel below the lower pressure rod 1322 also rotates accordingly, and then drives the model blank to rotate.

And a plurality of guide wheels 125 are correspondingly provided on the bottom side surface of the lower connecting plate 12. The outer contour of the guide wheel 125 contacts the vertical limiting plate 102 after the clamping module is positioned by the clamping module positioning mechanism, so that the clamping module can move smoothly when it is pushed forward subsequently.

[0043] Refer to Figure 1 or Figure 2 , a clamping module Z-axis positioning mechanism 103 is further provided above the top of each processing station on the above-mentioned support frame 100. The clamping module Z-axis positioning mechanism is preferably a Z-axis positioning cylinder.
