Technical Field

[0001] This invention relates to the field of powered tool holders, and more specifically to a powered rotary eccentric tool holder. Background Technology

[0002] A powered tool holder refers to a tool holder that is mounted on a powered tool turret and can be driven by a servo motor. This type of tool holder is generally used on mill-turn machines, and a few can also be used on machining centers with powered tool turrets.

[0003] When processing "soft metals," such as aluminum alloy plates and lithium alloys, especially when processing these precious metals in irregular shapes, the existing power rotary eccentric tool holders cannot meet the processing requirements. Moreover, the existing power rotary eccentric tool holders can only perform single-function processing on the workpiece. When multi-angle eccentric processing or processing of irregularly shaped workpieces is required, the existing power rotary eccentric tool holders cannot meet the special processing requirements.

[0004] Therefore, it is necessary to invent a powered rotary eccentric tool holder. Summary of the Invention

[0005] To address this issue, the present invention provides a powered rotary eccentric tool holder. A clamping device secures the tool within three sets of sliding clasps. Simultaneously, a drive motor rotates a triangular rotor (first rotor) within the inner mounting rail (first mounting rail). A double-ended stud drives a second triangular rotor (second rotor) at the top of the first triangular rotor to rotate, which in turn rotates the clamping device fixed to the second triangular rotor. This achieves multi-angle machining of the workpiece, thus solving the problem that existing powered rotary eccentric tool holders cannot meet specific machining requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power-driven rotary eccentric tool holder, comprising a deflection device, a clamping device, and a tool holder. The deflection device is located at the top of the tool holder and connected to the inner wall of the tool holder.

After the cutting tool is clamped, drive the power shaft connected to the tool holder to drive the tool holder to rotate, thereby driving the cutting tool on the top of the tool holder to rotate, thereby machining the workpiece.

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] See attached document Figure 1-13 The present invention provides a power-driven rotary eccentric tool holder, comprising a deflection device 100, a clamping device 200, and a tool holder 300. The deflection device 100 is located at the top of the tool holder 300 and connected to the inner wall of the tool holder 300. The clamping device 200 is located inside the deflection device 100 and connected to the top of the deflection device 100. The deflection device 100 includes a limiting steel ring 101. The bottom of the limiting steel ring 101 is fixedly connected to the inner wall of the top of the tool holder 300. A receiving inner rail 102 is provided on the inner wall of the bottom of the limiting steel ring 101. A receiving inner rail 203 is provided on the inner wall of the limiting steel ring 101. An eccentric component 110 is connected to the inner wall of the receiving inner rail 102. The clamping device 200 is connected to the inner wall of the receiving inner rail 203.

[0031] The eccentric assembly 110 includes a triangular rotor 111. An internal gear ring 112 is fixedly installed on the inner wall of the triangular rotor 111. An annular groove 113 is opened on the top of the triangular rotor 111 and the annular groove 113 coincides with the center line of the internal gear ring 112. A top cover 114 is provided on the top of the triangular rotor 111 and the bottom of the top cover 114 is engaged with the annular groove 113. A locking hole 115 is opened on the inner wall of the bottom of the top cover 114.

[0032] A hollow base frame 104 is fixedly installed on the inner walls of both sides of the bottom of the limiting steel ring 101. A limiting gear 105 is fixedly installed on the top of the hollow base frame 104. The limiting gear 105 meshes with the internal gear ring 112, and the triangular rotor 111 is in movable contact with the receiving inner rail 102. The meshing of the limiting gear 105 with the internal gear ring 112 limits the rotation of the triangular rotor 111. An eccentric column 116 is rotatably connected to the inner wall of the hollow base frame 104. The eccentric column 116 rotates through the middle of the limiting gear 105. A locking block 117 is fixedly installed on the top of the eccentric column 116 and engages with the locking hole 115. A motor 120 is fixedly installed at the bottom of the hollow base frame 104. A worm gear 118 is fixedly installed at the bottom of the eccentric column 116. A worm 119 is rotatably connected to the inner wall of the bottom of the hollow base frame 104 and meshes with the worm gear 118. The output shaft of the motor 120 is connected to the worm 119. The end wall is fixedly connected, and the worm 119 meshes with the worm wheel 118 to limit the rotation of the tool, effectively preventing the triangular rotor 111 from moving around when the tool rotates. Specifically, when it is necessary to perform multi-angle eccentric machining or machining of irregularly shaped workpieces, the output shaft of the drive motor 120 drives the worm 119 to rotate, so that the worm 119 meshes with the worm wheel 118, thereby driving the eccentric column 116 at the top of the worm wheel 118 to rotate. The locking block 117 at the top of the eccentric column 116 cooperates with the locking hole 115 at the bottom of the top cover 114, so that the top cover 114 drives the triangular rotor 111 at the bottom to rotate, so that the internal gear ring 112 inside the triangular rotor 111 meshes with the limiting gear 105, thereby causing the triangular rotor 111 to rotate within the inner rail 102, and its rotation trajectory is the same as the inner wall shape of the inner rail 102.

[0033] Furthermore, the clamping device 200 includes a jaw assembly 210, which includes a chuck 211. The top of the chuck 211 has a sliding groove 212, which is arranged in three sets in a circumferential array. A geared disc 213 is rotatably connected to the inner wall of the bottom of the chuck 211. A threaded slide rail 214 is fixedly installed on the top of the geared disc 213. Sliding locking pins 215 are slidably connected to the inner walls of the three sets of sliding grooves 212. Climbing teeth 216 are fixedly installed at the bottom of each of the three sets of sliding locking pins 215, and all three sets of climbing teeth 216 mesh with the threaded slide rails 214. The three sets of sliding locking pins 215 are slidably connected to the geared disc 213 through the cooperation of the climbing teeth 216 and the threaded slide rails 214. Specifically, the cutting tool is installed in the middle of the three sets of sliding chucks 215, and at the same time, any set of bevel gears 217 is rotated to mesh with the gear plate 213, thereby driving the threaded slide 214 on the top of the gear plate 213 to rotate, so that the threaded slide 214 meshes with the climbing teeth 216 at the bottom of the sliding chuck 215, thereby driving the three sets of sliding chucks 215 to slide in the slide groove 212 to clamp the cutting tool in the middle of the clamping chuck 211. After the cutting tool is clamped, the power shaft connected to the tool holder 300 is driven to drive the tool holder 300 to rotate, thereby driving the cutting tool on the top of the tool holder 300 to rotate, thereby machining the workpiece.

[0034] Furthermore, the bottom of the chuck 211 is provided with a sleeve 220 and the bottom of the chuck 211 is fixedly connected to the top of the sleeve 220. The top side wall of the sleeve 220 is provided with a rotating hole 221. There are three sets of rotating holes 221 arranged in a circumferential array. The inner walls of the three sets of rotating holes 221 are rotatably connected with bevel gears 217. The three sets of bevel gears 217 mesh with the gear plate 213. The outer wall of the sleeve 220 is fixedly installed with a flange 222. Specifically, when the triangular rotor 230 rotates, it drives the flange plate 232 at the top of the triangular rotor 230 to rotate, thereby driving the flange plate 222 fixedly connected to the flange plate 232 to rotate, thereby driving the sleeve 220 fixedly connected to the flange plate 222 and the chuck 211 to rotate, thereby driving the tool in the middle of the chuck 211 to rotate.

[0035] Furthermore, a triangular rotor 230 is provided at the bottom of the sleeve 220. The triangular rotor 230 is in movable contact with the inner wall of the receiving inner rail 103. The receiving inner rail 103 has the same shape as the receiving inner rail 102. The movement trajectory of the triangular rotor 230 is the same as that of the triangular rotor 111 and has the same shape as the receiving inner rail 103. A receiving annular groove 231 is provided at the top of the triangular rotor 230, and the bottom of the sleeve 220 engages with the receiving annular groove 231. A fixed installation is provided on the inner wall of the top of the triangular rotor 230. Flange 232 and flange 222 are fixedly connected to flange 232. Double-ended studs 130 are fixedly installed at the top triangle of triangular rotor 111, and the top of double-ended studs 130 is fixedly connected to the bottom triangle of triangular rotor 230. Specifically, when triangular rotor 111 rotates, it drives triangular rotor 230 to rotate synchronously through three sets of double-ended studs 130, thereby driving the tool at the top of triangular rotor 230 to rotate, thereby achieving the purpose of fine-tuning the machining angle and completing the machining of irregular workpieces.

[0036] The process of using this invention is as follows: A person skilled in the art installs the cutting tool into the middle of the three sets of sliding chucks 215, and at the same time rotates any set of bevel gears 217 to mesh with the gear plate 213, thereby driving the threaded slide 214 on the top of the gear plate 213 to rotate, so that the threaded slide 214 meshes with the climbing teeth 216 at the bottom of the sliding chuck 215, thereby driving the three sets of sliding chucks 215 to slide in the slide groove 212 to clamp the cutting tool in the middle of the clamping chuck 211. After the cutting tool is clamped, the power shaft connected to the tool holder 300 is driven to drive the tool holder 300 to rotate, thereby driving the cutting tool on the top of the tool holder 300 to rotate, thereby processing the workpiece;

[0037] When multi-angle eccentric machining or machining of irregularly shaped workpieces is required, the output shaft of the drive motor 120 drives the worm gear 119 to rotate, causing the worm gear 119 to mesh with the worm wheel 118, thereby driving the eccentric column 116 at the top of the worm wheel 118 to rotate. The locking block 117 at the top of the eccentric column 116 engages with the locking hole 115 at the bottom of the top cover 114, causing the top cover 114 to drive the triangular rotor 111 at the bottom to rotate. The internal gear ring 112 inside the triangular rotor 111 meshes with the limiting gear 105, thereby causing the triangular rotor 111 to rotate within the mounting inner rail 102. Its rotation trajectory is the same as the inner wall shape of the mounting inner rail 102. When the triangular rotor 111 rotates, it drives the triangular rotor 230 to rotate synchronously through three sets of double-headed studs 130, thereby driving the tool at the top of the triangular rotor 230 to rotate, thus achieving the purpose of fine-tuning the machining angle and completing the machining of irregularly shaped workpieces.
