Description

Technical Field

[0001] The utility model relates to the technical field of silver carving, in particular to an automatic turntable for silver carving. Background Technique

[0002] The special workbench for silver carving is a special workbench designed for carving silverware. It provides a series of functions and features, enabling silver carving artists to work more conveniently and effectively during the carving process. The silver carving process includes silver carving design, carving techniques, silverware materials, and processes, etc.

[0003] For example, the special workbench for silver carving disclosed in the Chinese patent document (Publication No.: CN220009310U), "comprises: a table body, the inside of the table body is hollow, a filter plate is arranged on the surface of the table body, and a collection component is arranged inside the table body; a bottom plate is fixedly arranged on the table body, a turntable is rotatably arranged on the bottom plate, a clamping seat is fixedly arranged on the turntable, a chute is symmetrically opened in the middle of the clamping seat, a clamping block is slidably arranged inside the chute, and a clamping component is arranged between the two clamping blocks; the table body is symmetrically provided with guard plates for supporting the opponent's arms on both sides of the bottom plate".

[0004] Although the above-mentioned existing special workbench for silver carving has achieved the effects of "being able to reduce the diffusion of dust and the impact on the operator during the carving process, reducing the impact caused by errors and instability, making the carving of silver more convenient and accurate, being able to adapt to different carving requirements, reducing interference and adjustment time during the carving process, improving work efficiency, and the clamping stability and turntable flexibility enabling artists to depict details more accurately and improving the precision and quality of the works", however, during the process of clamping the silverware with the clamping block and adjusting the position and angle of the silverware along the Y direction, manual operation is used as the driving source for both operations, resulting in low automation. Furthermore, relying on manual operation to adjust the clamping and position is likely to lead to insufficient operation stability, and long-term manual operation will increase the labor intensity of the operator. Especially when frequent adjustment or fixation of the clamping is required, it not only affects the work efficiency of the operator but also easily causes operation fatigue and an adverse working environment.

[0023] Through the above technical solution, when it is necessary to adjust the height of the silverware to be carved, the height of the silverware to be carved is adjusted through the cooperation of the lifting groove 121, the locking groove 122 and the locking bolt 123 in the elevating assembly.

[0024] A two-way lead screw 7 is rotatably sleeved on the inner wall of the chute of the processing table 6. A second reduction motor 8 for driving the two-way lead screw 7 is embedded and installed on the right side surface of the processing table 6. Symmetrically distributed X-axis clamping and rotating components are threadedly connected to both ends of the two-way lead screw 7 located in the chute of the processing table 6. When processing the silverware to be engraved, the X-axis clamping and rotating components are used to drive the silverware to be engraved to rotate in the X-axis direction while being clamped. The output shaft of the second reduction motor 8 is fixedly connected to one end of the two-way lead screw 7 through a coupling. The X-axis clamping and rotating component includes a clamp 13. The inner wall of one of the clamps 13 is threadedly connected to the outer surface of the left end of the two-way lead screw 7, and the inner wall of the other clamp 13 is threadedly connected to the outer surface of the right end of the two-way lead screw 7. A cavity 131 is formed inside one of the clamps 13. A first connecting rod 132 is rotatably sleeved on the right inner wall of the cavity 131. A ratchet 133 is fixedly sleeved on one end of the first connecting rod 132 located inside the cavity 131. Pin shafts 134 are rotatably sleeved on both inner walls of the cavity 131. Pawls 135 are fixedly sleeved on the outer surfaces of the pin shafts 134 located inside the cavity 131. Springs 137 are fixedly connected to both the lower surface of the pawl 135 and the inner bottom wall of the cavity 131.

Clamping blocks 139 are fixedly sleeved on the outer surfaces of both the first connecting rod 132 and the second connecting rod 138. A pressure sensor 1310 is fixedly installed on the left inner wall of the placement groove of one of the clamping blocks 139;

[0025] A controller 9 for controlling the second reduction motor 8, a first forward and reverse remote control switch 10 for controlling the first reduction motor 5, and a second forward and reverse remote control switch 11 for controlling the X-axis clamping and rotating component are respectively fixedly installed on the upper surface of the filter plate body 1.

[0026] The automatic turntable for silver carving realizes multi-directional automatic adjustment of the silverware to be engraved, including the position and angle in the X and Y directions, as well as the adjustment of the height. At the same time, the real-time monitoring and control of the clamping force are realized through the pressure sensor 1310, thereby improving the engraving accuracy and efficiency and ensuring that artists can create in the best state.

[0027] Working principle: Step 1: When in use, place the silverware to be engraved in the placement groove of the clamping block 139. Control the second reduction motor 8 to start through the controller 9. The second reduction motor 8 converts electrical energy into mechanical energy, drives the bidirectional lead screw 7 to rotate, drives the two X-axis clamping and rotating components at both ends of the bidirectional lead screw to move towards each other along the length direction of the bidirectional lead screw 7 as a whole, drives the clamping block 139 to clamp the silverware to be engraved, and through the pressure sensor 1310 arranged on the left inner wall of the placement groove of one of the clamping blocks 139, the clamping force applied by the clamping block 139 to the silverware to be engraved is detected in real time, and the signal is fed back to the controller 9. When the applied clamping force reaches the threshold value preset by the pressure sensor 1310, the controller 9 controls the second reduction motor 8 to stop starting;

[0028] Step 2: When it is necessary to adjust the Y-direction position and angle of the silverware to be engraved, press the forward rotation button of the first forward and reverse remote control switch 10 to drive the first reduction motor 5 to start. The first reduction motor 5 drives the worm 4 to mesh with the inner wall of the worm gear groove of the first support shaft 3, and then drives the lifting component and the X-axis clamping and rotating component above the first support shaft 3 to rotate in the Y direction of the first support shaft 3, so as to adjust the Y-direction position and angle of the silverware to be engraved. Conversely, press the reverse rotation button of the first forward and reverse remote control switch 10 to adjust the Y-direction position and angle of the silverware to be engraved in the reverse direction;

[0029] Step 3: When it is necessary to adjust the height of the silverware to be engraved, adjust the height of the silverware to be engraved through the cooperation of the lifting groove 121, the locking groove 122 and the locking bolt 123 in the lifting component;

[0030] Step 4: When it is necessary to adjust the X-direction position and angle of the silverware to be engraved, press the forward rotation button of the second forward and reverse remote control switch 11 to drive the micro reduction motor 136 to start. The micro reduction motor 136 drives the silverware to be engraved clamped by the clamping block 139 to rotate in the X direction along the second connecting rod 138. Conversely, press the reverse rotation button of the second forward and reverse remote control switch 11 to adjust the silverware to be engraved in the reverse direction along the X direction of the second connecting rod 138.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
