DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and by way of examples. The following examples are intended to explain the present invention but the present invention is not limited to the following examples.

[0024] Embodiment 1:

[0025] See also Figure 1 and Figure 2 , this embodiment provides a tool switching mechanism 1 for finishing aluminum parts, including a base 11, a turntable 12 is rotatably provided on the base 11, the number of turntables 12 is not less than two groups, and the turntable 12 is evenly arranged with several groups of tool placement parts 122 in the circumferential direction, and the base 11 is equipped with a driving assembly 13 for driving multiple groups of turntables 12 to rotate synchronously. In this embodiment, the corresponding tool needs to be placed on the tool placement part 122 of the turntable 12 before use, and the position of the tool placement part 122 is adjusted by rotating the turntable 12 to meet the diversified placement requirements of different tools. For example, when a specific type of tool needs to be replaced, the corresponding tool can be moved to the operating position by rotating the turntable 12, without manual adjustment, which greatly reduces the operation time. In addition, the design of evenly arranging the tool placement part 122 in the circumferential direction of the turntable 12 not only ensures the smoothness of tool switching, but also facilitates the reasonable arrangement of more tools in a limited space, thereby improving the applicability of the mechanism. The drive assembly 13 enables the tools on the turntables 12 to switch positions simultaneously, which is particularly suitable for double-station or multi-station processing operations, thereby improving production efficiency and consistency of tool switching.

[0026] The turntable 12 includes a disc 121, and a plurality of tool placement portions 122 are evenly arranged on the periphery of the disc 121 for accommodating and fixing tools of different specifications. The tool placement portion 122 is designed as a plug-in structure, and a tool socket 123 is plugged in and adapted therein. The tool socket 123 is tightly connected to the tool through a standardized interface to ensure that the tool maintains stability during processing. The annular rib 124 arranged on the periphery of the disc 121 is mainly used to constrain the tool socket 123. The annular rib 124 is slightly higher than the top of the tool socket 123, and can prevent the tool from falling off due to centrifugal force when the turntable 12 rotates or the tool is switched. At the same time, the annular rib 124 can effectively prevent damage to the tool caused by external collisions, thereby improving the overall reliability of the mechanism.

[0027] The driving assembly 13 includes a driving motor 131, which is the core power source of the tool switching mechanism 1 and is connected to a synchronous belt transmission mechanism 132 through a motor shaft. The speed of the driving motor 131 can be adjusted by connecting to a motor controller (usually a servo motor connected to an external motor controller drive) to meet different tool switching requirements and processing beat requirements. The driving motor 131 is connected to the turntable 12 through a synchronous belt transmission mechanism 132. The synchronous belt transmission mechanism 132 includes a driving wheel 133 and a driven wheel 134. The driving wheel 133 is mounted on the shaft of the driving motor 131, and two sets of driven wheels 134 are respectively connected to the corresponding indexing mechanism 136 of the turntable 12. The turntable 12 is connected to the indexing mechanism 136, which adopts a curved cam 137 indexing mechanism 136, including a turntable 138 and a curved cam 137, and the curved cam 137 has a spiral profile on its periphery. The spiral profile matches the rollers 139 evenly arranged on the outer circumference of the turntable 138, and the indexing mechanism 136 can convert the continuous rotation of the drive motor 131 into intermittent rotation of the turntable 12, ensuring that the tool can accurately stay at the set position when switching. In this embodiment, the number of rollers 139 is consistent with the number of tool placement parts 122, ensuring that the indexing action in each switching process completely matches the spacing of the tools, ensuring the consistency of the switching process.

[0028] In actual work, when the driving motor 131 is started, the synchronous belt transmission mechanism 132 drives the arc cam 137 to rotate, and the spiral profile pushes the roller 139 to gradually complete the indexing action, thereby driving the turntable 12 to rotate intermittently, so that the tools reach the switching position one by one. The entire driving process is stable and efficient, and can meet the requirements of high-precision aluminum finishing for fast tool switching.

[0029] Through the above-mentioned structural design, the drive assembly 13 of the present invention not only realizes the precise intermittent rotation of the turntable 12, but also greatly improves the automation level and stability of the tool switching mechanism 1, thereby effectively solving the quality and efficiency problems of aluminum parts processing caused by inaccurate switching or insufficient speed in the prior art.

[0030] Embodiment 2:

[0031] See also Figure 3 and Figure 4 This embodiment also provides a processing platform 2, which aims to solve the problems of low processing efficiency, insufficient precision and inconvenient tool switching in the traditional processing platform 2. Through reasonable design and combination with the tool switching mechanism 1 described in Example 1, the processing platform 2 can realize automated and high-precision aluminum processing, adapt to complex processing requirements, and greatly improve production efficiency and processing quality. The processing platform 2 includes the aluminum finishing tool switching mechanism 1 described in Example 1, a processing host 21 and a processing base 22.

[0032] The processing host 21 is equipped with a first linear module 211, which drives the slide to move and can realize the vertical up and down movement of the processing arm 213. Two groups of processing arms 213 are symmetrically arranged on the slide of the first linear module 211. The first linear module 211 drives the slide to drive the two groups of processing arms 213 to move up and down, so that the processing platform 2 can process two aluminum parts at the same time, improving work efficiency. Two groups of turntables 12 are also arranged corresponding to the processing arms 213, and are respectively arranged on both sides of the processing host 21. The configuration of the turntable 12 works in coordination with the tool switching mechanism 1 to achieve precise docking of the tool and the processing point.

[0033] In this embodiment, the processing base 22 comprises a first seat body 221 arranged at the front side of the processing host 21, the first seat body 221 is slidably connected to the second seat body 222 and is adapted to be equipped with a second linear module 232 for driving the second seat body 222 to slide forward and backward, the second seat body 222 comprises a fixed seat 223 slidably arranged on the slide table of the second linear module 232 and a movable seat 224 slidably connected to the fixed seat 223, the movable seat 224 is provided with a third linear module 233 for driving it to slide left and right relative to the fixed seat 223, the movable seat 224 is provided with two sets of three-jaw chucks 225 for clamping aluminum parts and a workpiece motor 226 for driving the three-jaw chucks 225 to rotate. The movable seat 224 comprises a movable frame 227, side plates 228 are fixed at both ends of the movable frame 227, a mounting plate 229 is rotatably connected between the side plates 228, the mounting plate 229 is arranged above the movable frame 227 and is equipped with a swing plate servo 230 for driving it to swing forward and backward relative to the side plates 228. This allows the aluminum part to move horizontally in the front, back, left, and right directions during processing, and can also be tilted forward and backward through the swing plate servo 230, complementing the left and right tilt of the clamp 218, thereby meeting the multi-degree-of-freedom adjustment function required for the processing operation of the aluminum part.

[0034] The processing arm 213 is provided with a clamping jaw 218 for clamping a tool and a first steering gear 214 for driving it to swing toward one side of the turntable 12. The first steering gear 214 drives the processing arm 213 to swing in a horizontal plane to adjust the position of the processing arm 213, so as to switch the processing station and the tool changing station of the processing arm 213. Specifically, the processing arm 213 includes a swing arm 215, which is connected to the slide of the first linear module 211 through the first steering gear 214. The end of the swing arm 215 is connected to a mounting seat 217 through a second steering gear 216. The mounting seat 217 can rotate in a vertical direction (swing left and right) to adjust the left and right tilt angle of the processing arm 213 when processing aluminum parts, and the mounting seat 217 is provided with a tool motor 219 for driving the clamping jaw 218 to rotate to achieve cutting of aluminum parts. A shielding door 231 is provided at the front side of the turntable 138 in this embodiment, which can prevent the debris generated during the processing of the workpiece from invading the turntable 138 and causing the tool to be contaminated.

[0035] The specific working principle of the processing platform 2 is as follows:

[0036] Tool switching and positioning: The two sets of turntables 12 are rotated synchronously through the drive assembly 13 to rotate the tool slot to the tool changing position. The first linear module 211 drives the slide to drive the processing arm 213 to move upward, so that the original tool is separated from the aluminum part, and the processing arm 213 is driven to swing to the tool changing station through the first servo 214, and then the processing arm 213 is driven downward by the first linear module 211. At this time, the original tool is removed by the clamp 218. After the clamp 218 is lifted, the required tool is rotated to the bottom of the clamp 218 through the turntable 12 and grabbed again to realize the tool switching.

[0037] Fixing and adjustment of aluminum parts: The movable seat 224 of the processing base 22 clamps and fixes the aluminum parts through the three-jaw chuck 225. At the same time, the three-jaw chuck 225 can be driven by the workpiece motor 226 to drive the aluminum parts to rotate. The second linear module 232 and the third linear module 233 can also drive the aluminum parts to move in the horizontal direction. The mounting plate 229 is driven by the swing plate servo 230 to drive the aluminum parts to swing back and forth, so as to adjust the processing position of the aluminum parts.

[0038] Aluminum processing: The first linear module 211 drives the slide to move up and down, and the two processing arms 213 adjust the tool position angle to the aluminum processing surface under the control of the first servo 214 and the second servo 216. In addition, the tool motor 219 can drive the clamp 218 to drive the tool to rotate to achieve aluminum drilling, milling and other processing operations.

[0039] The processing platform 2 adopts a dual-station design to support the simultaneous processing of two groups of workpieces, significantly improving the production efficiency of the equipment. The two sets of synchronously rotating turntables 12 can quickly switch tools, greatly shorten the processing preparation time, and meet the needs of continuous processing of multiple processes. The multi-degree-of-freedom adjustment design of the processing arm 213 and the processing base 22 can meet the needs of complex shape processing of workpieces, while achieving high-precision tool and workpiece positioning, ensuring the consistency and stability of processing quality, and is suitable for a variety of aluminum processing scenarios.
