Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a machining equipment for new energy battery base rods. Background Technology

[0002] The power battery system of new energy vehicles typically consists of battery modules, a battery management system (BMS), and a battery pack casing. Among these, the battery base (also known as a battery bracket, battery tray, or battery support) is the core load-bearing structure within the battery pack casing. As the mounting base for the battery modules, the battery base not only needs to bear the weight of the hundreds of kilograms of battery cell modules but also integrates multiple functions such as thermal management, collision protection, sealing, and vehicle installation connections. It is a key component for ensuring the safety and reliability of the battery system.

[0003] Battery bases typically consist of a frame, base plate, and mounting lugs. The frame is constructed from multiple crossbeams and side beams (i.e., long metal rods) welded together. These long metal rods are mostly made of extruded aluminum alloy profiles, achieving both lightweight design and sufficient strength. As the energy density of battery systems continues to increase, thermal management requirements are becoming increasingly stringent. More and more battery bases are integrating liquid cooling into the frame rods; this involves creating complex three-dimensional cooling channels within the rods, through which coolant circulates to remove the heat generated during battery charging and discharging. Therefore, as... Figure 1 As shown, these metal rods (100) need to be machined with various types of structures, including battery module mounting holes, wire harness holes, cooling water channel interfaces, sealing grooves, and various channel structures in the cooling flow channels.

[0004] However, the machining of the aforementioned long metal rods (100) faces numerous difficulties in the existing technology. Firstly, these rods are typically quite long, making them prone to forced vibrations under cutting forces during milling and turning. In particular, the internal cooling channels further complicate the cross-sectional structure of the rods and reduce the local wall thickness, weakening the workpiece's rigidity and causing frequent machining vibrations, which severely affects machining accuracy. Secondly, the long metal rods require machining of multiple parts and dispersed processes, typically requiring multiple processes such as roughing the profile, drilling, milling, tapping, and finishing the cooling channels on various machine tools of different types. Each change of process necessitates re-clamping the workpiece, and the cumulative positioning errors from multiple clampings accumulate. Given the large size of the long rods, the cumulative effect of form and position errors is even more pronounced, making it difficult to guarantee the positional accuracy between the mounting holes and the relative accuracy between the cooling channels and the sealing surface. If the flatness of the sealing surface or the coaxiality of the holes exceeds the tolerance, it may lead to sealing failure, uneven bolt assembly, and other problems, resulting in leakage or structural deformation. Third, the multi-process and multi-clamping processing mode leads to frequent transfer of workpieces between different equipment, with many intermediate links and long auxiliary time, which not only seriously restricts production efficiency, but also makes it difficult to meet the urgent needs of the new energy vehicle industry for large-scale, high-speed production.

[0005] Therefore, there is an urgent need for a specialized device capable of performing high-precision and high-efficiency processing on the aforementioned long metal rods. Summary of the Invention

[0006] In view of this, the present invention proposes a processing equipment for new energy battery base rods, with the aim of achieving high-precision and high-efficiency batch processing of new energy battery base rods.

[0007] The technical solution of this invention is implemented as follows:

[0008] A new energy battery base rod processing equipment, comprising:

[0009] frame;

[0010] A clamping and adjusting mechanism includes a clamping platform, two end positioning components disposed on the clamping platform, a plurality of intermediate positioning components disposed between the two end positioning components, and a rotating mechanism for driving the clamping platform to rotate. The end positioning components and the intermediate positioning components are arranged linearly along a first direction. The two end positioning components are used to clamp the two ends of the workpiece to achieve axial fixation, and the intermediate positioning components are used to clamp the workpiece to achieve radial fixation. The rotating mechanism is used to drive the clamping platform to rotate around a first axis, which is arranged along the first direction. The clamping and adjusting mechanism has a plurality of components arranged side by side along a second direction, which is perpendicular to the first direction on a horizontal plane.

[0011] A machining spindle, which corresponds one-to-one with the clamping and adjusting mechanism, is movably mounted on the machine frame along a first direction, a second direction, and a third direction, wherein the third direction is vertical;

[0012] The tool magazine includes a tool holder and multiple tool holders mounted on the tool holder. The number of tool holders corresponds one-to-one with the machining spindle. The tool holder is movably mounted on the frame along a first direction.

[0013] As a further optional solution, the frame is provided with a first drive mechanism, a second drive mechanism and a third drive mechanism;

[0014] The first driving mechanism includes a gantry bracket slidably mounted on the frame along a first direction and a first lead screw mechanism for driving the gantry bracket to slide.

[0015] The second drive mechanism includes a translation slide table that is slidably mounted on the gantry bracket along a second direction and a second lead screw mechanism for driving the translation slide table to slide.

[0016] The third driving mechanism includes a lifting seat that is slidably disposed on the translation slide along a third direction and a third lead screw mechanism for driving the lifting seat to slide.

[0017] The machining spindle is mounted on the lifting platform.

[0018] As a further optional solution, the frame is also provided with a fourth lead screw mechanism for driving the tool holder to slide.

[0019] As a further optional solution, the clamping platform is provided with a plurality of mounting holes arranged along the first direction;

[0020] The end positioning component is bolted to the mounting hole to be fixed to the clamping support;

[0021] The intermediate positioning component includes a support base, a side pressing component, and a top pressing component. The support base is bolted to the mounting hole to be fixed on the clamping platform. The support base is provided with a clamping groove for inserting the workpiece. The side pressing component is used to press the workpiece against the inner wall of the clamping groove, and the top pressing component is used to press the workpiece against the bottom surface of the clamping groove.

[0022] As a further optional solution, the clamping support is provided with a groove, the groove is arranged along the first direction, and the mounting holes are provided in two rows and are respectively located on both sides of the groove;

[0023] The bottom of the support base has a protrusion for engaging with the groove, and the protrusion is slidably disposed along the groove.

[0024] As a further alternative, the end positioning assembly includes a first pressure block and a first driver for driving the first pressure block to move along a first direction.

[0025] As a further alternative, the side pressure assembly includes a second pressure block and a second driver for driving the second pressure block to move in a second direction, the second driver being disposed on the support base.

[0026] As a further alternative, the top pressure assembly includes a third pressure block and a third driver for driving the third pressure block to move in a third direction, the third driver being disposed on the support base.

[0027] As a further alternative, the rotating mechanism includes a hinged seat, a turntable, and a rotary driver for driving the turntable to rotate, with one end of the clamping platform hinged to the hinged seat and the other end fixed to the turntable.

[0028] As a further optional solution, the area directly above the clamping and adjusting mechanism is defined as the processing area;

[0029] In the initial state, the tool magazine is located outside the machining area;

[0030] In the tool changing state, the tool magazine enters at least partially into the machining area.

[0031] Compared with the prior art, the present invention has the following technical effects:

[0032] 1. It facilitates multi-face machining in a single setup, reducing cumulative errors and suppressing vibration;

[0033] In the clamping and positioning mechanism, the end positioning components and intermediate positioning components jointly provide axial and radial support for the long metal rod. Together with the rotating mechanism, they drive the clamping platform to rotate around the first axis, allowing the long metal rod to undergo milling and turning of multiple surfaces in a single clamping operation. This method avoids the cumulative positioning errors caused by repeated workpiece disassembly and assembly in traditional multi-process machining. Simultaneously, the multiple intermediate positioning components continuously provide radial support to the long metal rod during machining, helping to reduce forced vibrations under cutting forces, thereby improving the positional accuracy between mounting holes and the relative accuracy between cooling channels and sealing surfaces.

[0034] 2. It facilitates the parallel processing of multiple long metal rods, increasing output per unit time;

[0035] Multiple clamping and adjusting mechanisms are arranged side by side along the second direction, each corresponding to a machining spindle capable of independent three-axis movement, enabling the equipment to process multiple long metal rods simultaneously. This configuration concentrates processes that originally needed to be completed sequentially on multiple machine tools into parallel execution on a single machine, reducing the workpiece transfer time between different machines, thus improving production efficiency and making it suitable for the mass production needs of long metal rods for new energy vehicle battery bases.

[0036] 3. It facilitates the centralized completion of multiple processes on the same equipment, improving the overall processing continuity;

[0037] Building upon the aforementioned single-clamping, multi-station parallel machining, the machining spindles can move upwards in the first, second, and third directions. Combined with a tool magazine that can move as a whole along the first direction, this allows each machining spindle to quickly acquire or change tools from the tool magazine. When all machining spindles operate synchronously, tools can be changed according to the process requirements, thus enabling the completion of different processes such as roughing, drilling, milling, tapping, and finishing of cooling channels on the same machine. The clamping, parallel machining, and tool changing functions are interconnected, eliminating the need for separate machine tools for each process or frequent reliance on external tool changing devices, thereby reducing workpiece interruptions and waiting times between different machining stages.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0060] refer to Figures 1 to 11 An embodiment of the present invention illustrates a new energy battery base rod processing equipment, including a frame 1, a clamping and adjusting mechanism 2, a processing spindle 3, and a tool magazine 4;

[0061] The clamping and adjusting mechanism 2 includes a clamping platform 21, two end positioning components 22 disposed on the clamping platform 21, a plurality of intermediate positioning components 23 disposed between the two end positioning components 22, and a rotating mechanism 24 for driving the clamping platform 21 to rotate. The end positioning components 22 and the intermediate positioning components 23 are arranged in a straight line along a first direction X. The two end positioning components 22 are used to clamp the two ends of the workpiece to achieve axial fixation, and the intermediate positioning components 23 are used to clamp the workpiece to achieve radial fixation. The rotating mechanism 24 is used to drive the clamping platform 21 to rotate around a first axis, which is disposed along the first direction X. The clamping and adjusting mechanism 2 has a plurality of components arranged side by side along a second direction Y, which is perpendicular to the first direction X on a horizontal plane.

[0062] The machining spindle 3 corresponds one-to-one with the clamping and adjusting mechanism 2. The machining spindle 3 is movable on the frame 1 along the first direction X, the second direction Y and the third direction Z, where the third direction Z is vertical.

[0063] The tool magazine includes a tool holder and multiple tool holders 42 mounted on the tool holder 41. The number of tool holders 42 corresponds one-to-one with the machining spindle 3. The tool holder 41 is movably mounted on the frame 1 along the first direction X.

[0064] Among them, the aforementioned workpiece is, for example, Figure 1 The metal rod 100 shown is part of the frame of the battery base.

[0065] Specifically, the clamping and adjusting mechanism 2 is used to support and fix the long metal rod 100 to be processed. The clamping platform 21 is a long strip plate, and the end positioning components 22 are fixed near both ends of the clamping platform 21 and are arranged opposite each other along the first direction X to clamp the two ends of the long metal rod 100, thereby restricting the axial displacement of the long metal rod 100 in the first direction X. Between the two end positioning components 22, a plurality of intermediate positioning components 23 are arranged in a straight line along the first direction X. These intermediate positioning components 23 are used to fix the long metal rod 100 radially (i.e., in a direction perpendicular to the first direction X) and can restrict the movement of the long metal rod 100 in the horizontal and vertical directions. The rotating mechanism 24 is connected to the clamping platform 21 and can drive the clamping platform 21 to rotate around a first axis, which is arranged along the first direction X, i.e., the center line of the length direction of the clamping platform 21. By rotating, the metal rod 100 clamped on it can be switched between different sides, which facilitates the machining spindle 3 to perform milling and turning on multiple sides of the metal rod 100.

[0066] The tool magazine 4 is used to store various types of cutting tools to meet the machining requirements of various grooves, holes, sealing surfaces, cooling channel interfaces, and other structures on the long metal rod 100. The tool magazine 4 includes a tool holder and multiple sets of tool holders 42 mounted on the tool holder. The number of tool holders 42 corresponds one-to-one with the number of machining spindles 3, that is, each machining spindle 3 has a corresponding set of tool holders 42. The tool holder is movably mounted on the frame 1 along the first direction X.

[0067] In this embodiment, reference Figure 10 and Figure 11 The area directly above the clamping and adjusting mechanism 2 (i.e., the area where the machining spindle 3 cuts the workpiece) is defined as the machining area K. In the initial state, the tool magazine 4 is located outside the machining area K; in the tool changing state, the tool holder moves along the first direction X, driving the corresponding tool holder 42 to at least partially enter the machining area K, so that the machining spindle 3 can complete the tool change without leaving the machining area K too far.

[0068] It should be noted that, since the length of the long metal rod 100 is usually large (e.g., more than 1 meter), the dimension of the frame 1 along the first direction X is correspondingly long. If the tool magazine 4 is fixed in position, the machining spindle 3 needs to move a long distance along the first direction X between the machining area and the tool magazine 4 each time it changes tools. Since there are many parts to be machined on the long metal rod 100 and the number of tool changes is frequent, the accumulated time of multiple long-distance movements results in a long downtime window, which has a significant impact on machining efficiency. In this embodiment, the tool magazine 4 can move along the first direction X as a whole. When changing tools, the tool magazine 4 actively moves closer to the location of the machining spindle 3, so that the machining spindle 3 can dock with the tool magazine 4 without long-distance movement, thereby shortening the idle travel time of each tool change. The time saved by multiple tool changes is more significant, which is conducive to improving the overall machining efficiency of the equipment. At the same time, when not changing tools, the tool magazine 4 is moved out of the machining area, avoiding interference between the tool magazine 4 and the tools on it and the machining spindle 3, the clamping and adjusting mechanism 2 or the workpiece, and maintaining the unobstructed access of the machining area.

[0069] In this embodiment, the processing equipment first adjusts the end positioning components 22 and intermediate positioning components 23 on multiple clamping and adjusting mechanisms 2 to appropriate positions based on the length of the metal long rod 100 to be processed and the position of the part to be processed. Multiple metal long rods 100 (from the same batch and of the same specifications) are placed on each clamping and adjusting mechanism 2, with the end positioning components 22 clamping both ends and the intermediate positioning components 23 radially pressing the middle section. Then, each processing spindle 3 moves from its initial position above the corresponding workpiece to cut the metal long rod 100. Because each processing spindle 3 operates synchronously, multiple metal long rods 100 are processed simultaneously. When a tool change is required, the tool magazine 4 moves along the first direction X to a position close to the processing spindle 3. After the processing spindle 3 completes the tool change, the tool magazine 4 exits the processing area, and the processing spindle 3 continues processing. If different sides of the long metal rod 100 need to be machined, the rotating mechanism 24 drives the clamping platform 21 to rotate around the first axis, so that the surface of the long metal rod 100 to be machined faces upward, and the machining spindle 3 then performs the machining. The entire machining process completes multiple operations and machining of multiple sides in one clamping, without the need to transfer the long metal rod 100 between different machine tools.

[0070] The beneficial effects of this embodiment are as follows: Multiple clamping and adjusting mechanisms 2 are arranged side by side, each corresponding to a machining spindle 3 that can move in three axes. This allows the equipment to process multiple long metal rods 100 simultaneously, concentrating the processes that were originally scattered across multiple machine tools into one machine for parallel execution. This reduces the transfer time of the long metal rods 100 between different machines, which is beneficial for improving production efficiency and is suitable for mass production. The end positioning component 22 and the intermediate positioning component 23 together provide axial and radial fixation for the workpiece, which helps to suppress the forced vibration of the long rods during milling and turning, and improves machining accuracy. The rotating mechanism 24 allows the long metal rods 100 to complete the machining of multiple sides in one clamping, avoiding the cumulative positioning error caused by multiple clamping, which is also beneficial for improving machining accuracy. The tool magazine 4 is movable along the first direction X, and actively moves closer to the machining spindle 3 when changing tools, reducing the long idle travel of the machining spindle 3. This is especially suitable for batch processing scenarios where the frame 1 is long and the number of tool changes is frequent. At the same time, the tool magazine 4 is located outside the machining area when not changing tools, which helps to keep the machining area unobstructed and avoid interference.

[0071] In some embodiments, to facilitate the three-axis movement of the machining spindle 3, such as... Figure 3 and Figure 11 As shown, the frame 1 is provided with a first drive mechanism 11, a second drive mechanism 12, and a third drive mechanism 13; the first drive mechanism 11 includes a gantry bracket 111 slidably disposed on the frame 1 along a first direction X and a first lead screw mechanism 112 for driving the gantry bracket 111 to slide; the second drive mechanism 12 includes a translation slide 121 slidably disposed on the gantry bracket 111 along a second direction Y and a second lead screw mechanism (not marked in the figure) for driving the translation slide 121 to slide; the third drive mechanism 13 includes a lifting seat 131 slidably disposed on the translation slide 121 along a third direction Z and a third lead screw mechanism (not marked in the figure) for driving the lifting seat 131 to slide; the machining spindle 3 is disposed on the lifting seat 131.

[0072] Specifically, taking the first lead screw mechanism 112 as an example, refer to... Figure 3The first lead screw mechanism 112 includes a first guide rail 1121, a first screw 1122, and a first motor 1123. The first guide rail 1121 is mounted on the frame 1 along a first direction X. The gantry bracket 111 is slidably engaged with the first guide rail 1121. The first screw 1122 is rotatably mounted on the frame 1 and is parallel to the first guide rail 1121. The first motor 1123 is driven by the first screw 1122 to drive the screw to rotate. The gantry bracket 111 is threadedly connected to the first screw 1122. When the first screw 1122 rotates, it can drive the gantry bracket 111 to move along the first guide rail 1121 (i.e., the first direction X). The second and third lead screw mechanisms operate on the same principle, so their specific structures are not shown.

[0073] In this embodiment, a gantry bracket 111 structure is adopted, which spans multiple parallel clamping and adjusting mechanisms 2, providing good rigidity and the ability to withstand large cutting forces. All three drive mechanisms employ lead screw and nut pairs for high positioning accuracy and reliable repeatability, which helps meet the machining accuracy requirements of the battery base metal rod 100. Simultaneously, the gantry bracket 111 moves along the first direction X, cooperating with the tool magazine 4's movement along the first direction X, allowing the tool magazine 4 and the machining spindle 3 to approach each other in the first direction X during tool changes, shortening the idle travel during tool changes. Furthermore, integrating the machining spindle 3 onto the lifting seat 131 results in a compact structure and facilitates synchronous control of multiple spindles.

[0074] In the above scheme, the frame 1 is also provided with a fourth lead screw mechanism 14 for driving the tool-laying frame 41 to slide. The working principle of the fourth lead screw mechanism 14 is the same as that of the first lead screw mechanism 112, so it will not be described in detail. Of course, the tool-laying frame 41 can also be moved by a rack and pinion drive.

[0075] In some embodiments, reference Figures 5 to 8The clamping platform 21 is provided with a plurality of mounting holes 211 arranged along the first direction X; the end positioning components 22 are bolted to the mounting holes 211 to be fixed on the clamping platform 21, and the two end positioning components 22 are arranged opposite to each other on the clamping platform 21 along the first direction X, and the two end positioning components 22 are used to clamp the two ends of the workpiece; the intermediate positioning component 23 is disposed between the two end positioning components 22, and the intermediate positioning component 23 includes a support base 231, a side pressing component 232 and a top pressing component 233. The support base 231 is bolted to the mounting holes 211 to be fixed on the clamping platform 21, and the support base 231 is provided with a clamping groove 2311 for inserting the workpiece. The side pressing component 232 is used to press the workpiece against the inner side wall of the clamping groove 2311, and the top pressing component 233 is used to press the workpiece against the bottom surface of the clamping groove 2311.

[0076] Specifically, multiple mounting holes 211 are threaded holes, arranged in a row along the first direction X, for fixing the end positioning components 22 and intermediate positioning components 23 with bolts. The two end positioning components 22 are respectively bolted to the corresponding mounting holes 211 on the clamping base 21 and are arranged opposite each other along the first direction X, for clamping the ends of the long metal rod 100 from both ends, achieving axial positioning of the long metal rod 100. Between the two end positioning components 22, one or more intermediate positioning components 23 are provided, each intermediate positioning component 23 also bolted to the mounting holes 211 on the clamping base 21. The support base 231 of the intermediate positioning component 23 has a clamping groove 2311 on its upper part. The width of the clamping groove 2311 should be greater than the width of the long metal rod 100, so that long metal rods 100 of different specifications can be placed into the clamping groove 2311.

[0077] In an exemplary application, the operator first fixes the two end positioning components 22 to the appropriate mounting holes 211 on the clamping base 21 using bolts, based on the actual length of the long metal rod 100 to be processed. Then, according to the length of the workpiece and the distribution of cutting forces during processing, an appropriate position is selected between the two end positioning components 22, and one or more intermediate positioning components 23 are fixed to the clamping base 21 using bolts. After the end positioning components 22 and intermediate positioning components 23 are installed on the clamping base 21, the long metal rod 100 can be clamped and fixed. Specifically, the end positioning components 22 are activated to clamp the two ends of the workpiece, and then the side pressing components 232 and top pressing components 233 are activated to press the workpiece from the side and above, respectively, to complete the clamping. If milling and turning of different sides of the workpiece is required, the clamping base 21 can be rotated around the first axis to the required angle by the rotating mechanism 24 without disassembling the workpiece.

[0078] Thus, the clamping and adjusting mechanism 2 of this embodiment can freely adjust the distance between the two end positioning components 22 and adjust the number and position of the intermediate positioning components 23, thereby adapting to metal long rods 100 of different specifications and reducing the design and manufacturing cost of special fixtures. The end positioning components 22 provide axial clamping, while the intermediate positioning components 23 located between the two ends cooperate with the side pressure components 232 and the top pressure components 233 through the clamping groove 2311 to provide multi-point radial fixation along the length of the workpiece. The side pressure and top pressure respectively restrict the displacement of the workpiece in the horizontal and vertical directions, which helps to suppress the forced vibration induced by the cutting force during milling and turning, reduce the probability of machining chatter marks, and thus improve machining accuracy.

[0079] In this embodiment, three intermediate positioning components 23 are provided. Having three intermediate positioning components 23 means that the workpiece has three radial support points along its length. These support points further subdivide the suspended section of the workpiece, allowing the cutting force to be more evenly distributed across each support point, which helps reduce workpiece deformation and forced vibration during the milling process. Of course, in other embodiments, other numbers of intermediate positioning components 23 can be provided.

[0080] In some embodiments, such as Figure 8 As shown, the clamping support 21 is provided with a groove 212, which is arranged along the first direction X. The mounting holes 211 are arranged in two rows and are respectively located on both sides of the groove 212. The bottom of the support 231 is provided with a protrusion 2312 for engaging the groove 212, and the protrusion 2312 is slidably arranged along the groove 212.

[0081] Specifically, on the one hand, during position adjustment, the groove 212 guides the protrusion 2312, making the intermediate positioning component 23 move more smoothly and accurately along the first direction X, avoiding possible misalignment during manual alignment. On the other hand, when the rotating mechanism 24 drives the clamping platform 21 to rotate, causing the side of the metal rod 100 to be processed to face upwards, the direction of gravity of the clamping platform 21, the intermediate positioning component 23, and the workpiece changes accordingly. The sidewall of the groove 212 abuts against the side of the protrusion 2312, jointly bearing the shear force and bending moment generated after rotation. At this time, the cooperation between the groove 212 and the protrusion 2312 bears most of the lateral load, reducing the stress on the bolts and improving the stability of the connection structure. This structural design allows the intermediate positioning component 23 to remain reliably fixed under rotation conditions, avoiding positioning offset caused by bolt loosening or shear deformation, thereby further ensuring processing accuracy.

[0082] Preferably, the support base 231 is bolted to at least two of the mounting holes 211 in each row of mounting holes 211. That is, the support base 231 is fixed by at least four bolts, further ensuring a stable connection.

[0083] In some embodiments, such as Figure 7 and Figure 8 As shown, the end positioning component 22 includes a first pressing block 221 and a first driver 222 for driving the first pressing block 221 to move along a first direction X.

[0084] The side pressure assembly 232 includes a second pressure block 2321 and a second driver 2322 for driving the second pressure block 2321 to move along the second direction Y. The second driver 2322 is disposed on the support base 231. The second direction Y is perpendicular to the first direction X.

[0085] The top pressure assembly 233 includes a third pressure block 2331 and a third driver 2332 for driving the third pressure block 2331 to move along a third direction Z. The third driver 2332 is disposed on the support base 231. The third direction Z is perpendicular to the second direction Y and the first direction X, respectively.

[0086] The first actuator 222, the second actuator 2322, and the third actuator 2332 can all be in the form of cylinders, hydraulic cylinders, or electric push rods. The specific shapes of the first pressure block 221, the second pressure block 2321, and the third pressure block 2331 can be designed according to actual needs, as long as they can stably contact the long metal rod 100.

[0087] In some embodiments, such as Figure 5 and Figure 6 As shown, the rotating mechanism 24 includes a hinge seat 242, a turntable 241, and a rotary driver (not shown) for driving the turntable 241 to rotate. One end of the clamping platform 21 is hinged to the hinge seat 242, and the other end is fixed to the turntable 241.

[0088] The rotary driver is connected to the turntable 241 via a transmission and can be in the form of a servo motor, stepper motor, or rotary cylinder.
