[0032] In this specific embodiment, the device uses a double-sided toothed synchronous belt 210 as an internal transmission component. The chuck body is made of lightweight aluminum alloy and has an added tooth shape that makes it easy for the hand to rotate, so that the person can operate the chuck to clamp and release it by hand without the aid of tools.

[0033] The transmission wheel housing 104 is mounted on the main body module 129. The rear cover plate 103 is fixedly connected to the side of the transmission wheel housing 104.

Multiple chuck sliders 107 are respectively disposed on the chuck body 129106. The chuck connector 108 is disposed on the side of the multiple chuck sliders 107. Multiple clamping rods 109 are respectively disposed on the side of the chuck connector 108. Multiple six-jaw connectors 110 are respectively fixedly connected to the side of the jaw connector. Multiple six-jaw rubber sleeves 111 are respectively fixedly sleeved on the corresponding six-jaw connectors 110. Multiple first height limiting screws 112 are respectively disposed on the corresponding six-jaw connectors 110. The double-sided synchronous belt 116 is respectively sleeved on the first tensioning wheel 117 and the two rotating wheels 118. This device, through the cooperation of multiple clamping rods 109 and six-jaw connecting rods 158, can perform clamping operations in different usage scenarios. The first drive input shaft 101 drives the tension wheel and double-sided synchronous belt 116 to rotate, which in turn drives the main shaft 113 to rotate, and then drives the chuck body 129106 to rotate. This device uses a double-sided toothed synchronous belt 210 as an internal transmission component. The lightweight chuck body is made of aluminum alloy, and its shape is enhanced with teeth for easy hand rotation, allowing for manual operation of clamping and releasing without tools. The jaws are divided into three kits according to different application scenarios: a conventional three-jaw gripper (clamping rods 109), and a six-point internal jaw (six-jaw connecting piece 110). Thus, this device can clamp workpieces of different shapes.

[0034] Secondly, one end of the main balance rod 124 is rotatably connected to the main body 129, and the other end of the main balance rod 124 is rotatably connected to the lifting plate 131. One end of the auxiliary balance rod 130 is rotatably connected to the main body 129, and the other end of the auxiliary balance rod 130 is rotatably connected to the lifting plate 131. The lifting bearing plate 123 is fixedly connected to the upper end of the lifting plate 131. The slide rail 132 is fixedly connected to the side of the lifting plate 131. The sliding connector 133 is slidably adapted to the slide rail 132. The two support rollers 134 are respectively fixedly connected to the side of the sliding connector 133. The side top wheel is disposed on the sliding connector 133. The side top hand screw 120 passes through the side plate of the side top wheel and is adapted to the sliding connector 133. The lifting knob 122 is connected to the lifting bearing. The upper end of plate 123 is rotatably connected. One end of screw 121 passes through the lifting bearing plate 123 and is rotatably connected to the lifting knob 122. The other end of screw 121 is adapted to the sliding connector 133. The guide rail protection component 128 is disposed inside the main body 129. The friction plate 127 is disposed between the balance main rod 124 and the main body 129. One end of the rotating shaft 137 is rotatably connected to the main body 129. The other end of the rotating shaft 137 is adapted to the self-locking nut 138. The disc spring 126 is disposed between the self-locking nut 138 and the main body 129. The locking wrench 125 is rotatably connected to the side of the main body 129. The second height limiting screw 136 is disposed on the side of the main body 129. The main body fixing knob 135 is rotatably connected to the side of the main body 129. The tail support module is divided into two stroke sections. A smaller stroke, controlled by a lead screw, is used for precise adjustment. The larger stroke, consisting of two balance bars, allows for greater vertical adjustment. The rotating shaft 137 features a damping design. For vertical adjustment, after loosening the locking wrench 125, the shaft can be manually moved up and down as needed until a suitable position is reached. Tightening the fixing screw then secures the structure, facilitating workpiece support. Turning the lifting knob 122, in conjunction with the screw 121, causes the sliding connector 133 to slide on the guide rail. The clamping tightness of the side top wheel can be adjusted by tightening the side top screw 120.

[0035] Meanwhile, the main lower foot plate 143 and the secondary lower foot plate 145 are respectively fixedly connected to the lower end of the guide rail profile 144, the two rubber feet 146 are respectively fixedly connected to the lower ends of the main lower foot plate 143 and the secondary lower foot plate 145, the end cap 147 is fixedly connected to the right end of the guide rail profile 144, the fixed upright plate 142 is fixedly connected to the upper end of the main lower foot plate 143, the transmission wheel housing 104 is fixedly connected to the left side of the fixed upright plate 142, the motor fixing plate 141 is fixedly connected to the left end of the transmission wheel housing 104, the two hand-tightening screws 140 are respectively rotatably disposed on the upper end of the fixed upright plate 142, and the drive motor 139 is connected to the left side of the motor fixing plate 141. The drive motor 139 is fixedly connected to the first drive input shaft 101, and its output end passes through the motor fixing plate 141 and the transmission wheel housing 104. The main shaft locking knob 148 is located on the main shaft 113 and on the left side of the transmission wheel housing 104. The inner conical rotating shaft 149 is located on the petal-shaped conical hollow shaft 150, which is located inside the transmission wheel housing 104 and is rotatably adapted to the fixed upright plate 142. The transmission synchronous wheel 151 is rotatably adapted to the bearing, which is rotatably connected to the fixed upright plate 142. The retaining ring 153 is located on the right side of the bearing. The rotating shaft 137 connecting the main body 129 module to the external module adopts an inner conical rotating shaft 149, with a corresponding petal-shaped conical hollow shaft 150 installed inside. When the main shaft locking knob 148 is tightened, the inner petal-shaped conical hollow shaft 150 will shrink towards the middle. After other modules are installed in place, tightening this knob can quickly realize power transmission with other modules.

[0036] Additionally, the lead screw knob 154 is rotatably connected to the side of the fixed sheet metal 155, one end of the lead screw 156 is rotatably connected to the inner wall of the fixed sheet metal 155, and the other end of the lead screw 156 is rotatably connected to the upper end of the support foot 159. The lead screw nut 157 is adapted to the lead screw 156 and is mounted on the support foot 159. One end of the connecting rod 158 is rotatably connected to the lead screw nut 157, and the other end of the connecting rod 158 is rotatably connected to the side of the support foot 159. The adjustable angle foot module is installed on both sides of the main body 129. This module allows for adjustment of the clamp angle. Most parts are designed with sheet metal, and the main drive mechanism uses a small M5 lead screw 156, thus allowing for a very thin profile when not in use, without occupying additional space. By turning the screw knob 154, the screw 156 is rotated, which in turn causes the screw nut 157 to move on the screw 156, thereby adjusting the angle position of the connecting rod 158 and the support foot 159.

[0037] When using the multifunctional fixture of this invention, for solid circular workpieces, the clamping plate module is assembled with the main body 129. If the workpiece is too long, a tail support module is needed to support the other end of the workpiece to prevent it from tilting or leaning. The height of the tail support module is adjusted according to the shape and size of the workpiece to ensure concentricity of the workpiece. At this point, the motor of the main body 129 module can be controlled to rotate, thereby driving the workpiece to rotate. Combined with a laser engraving machine, engraving work can be performed on the surface of circular products. For tapered circular workpieces, the tapered surface of the workpiece can be adjusted to a horizontal state by adjusting the adjustable angle foot module. If the angle exceeds the maximum angle of the adjustable angle foot module, a plate or other shim can be placed under the adjustable angle foot module, and then the horizontality can be precisely adjusted using the adjustable angle foot module. The overall length of this device is 13mm shorter than the prior art, the height is reduced by 50mm, and the width remains unchanged. The applicable workpiece diameter has increased from 135mm to 210mm. Previously, module switching required tightening and loosening screws with a wrench; the upgraded version requires no tools at all, reducing module replacement time by over 10 seconds (this doesn't include the time previously spent preparing tools, which would have been even longer). The original excessive height required disassembling the tail support for packaging, necessitating reassembly upon customer receipt. The current technology reduces the height by 50mm, eliminating the need to disassemble the tail support for shipping, allowing customers to use it immediately upon delivery. This reduced space also avoids interference with the laser head when used with a laser engraving machine (the previous technology required reversing the clamps, which is inconvenient and doesn't conform to normal operating habits). The original three-jaw chuck couldn't properly clamp large spherical workpieces (similar to large wine glasses); the upgraded six-jaw chuck can clamp these types of workpieces effectively. Adjustable angle feet have been added to the sides, accommodating cylindrical workpieces with a tapered middle section. When engraving on this tapered surface, this module can be adjusted to level the top of the tapered section, facilitating laser engraving.
