Description

Technical Field

[0001] This invention relates to the field of milling technology, specifically to a milling device for complex inspection fixture parts and its processing technology. Background Technology

[0002] In actual production applications, conventional milling equipment generally relies on specialized tooling fixtures to accurately position and securely clamp the workpiece. This constrains the workpiece's displacement and movement under milling cutting forces, ensuring the dimensional accuracy and surface quality of single-sided milling meet standards. Once all milling operations on one side of the workpiece are completed, the milling equipment's power must be shut off to completely interrupt the current processing flow. Then, on-site personnel must manually flip the workpiece, manually handling and repositioning it after it has been removed from its original clamping position. This entire process is manual and lacks continuity. After the workpiece has been flipped, it must be clamped again using tooling fixtures. The workpiece undergoes secondary positioning and calibration, with repeated adjustments to the clamping position and tightening force to re-fix the workpiece in a state that meets the processing requirements before the milling equipment can be restarted to carry out milling operations on the other side. In this traditional segmented processing mode, a series of auxiliary processes such as workpiece stopping and flipping, tooling reset and calibration, and secondary clamping and positioning consume a large amount of non-processing effective time. There is a significant lag and discontinuity in the connection between each processing process, making it impossible to achieve continuous and integrated milling processing. This not only significantly lengthens the overall processing cycle of a single workpiece but also directly restricts the overall operating speed of milling processing, resulting in low effective processing utilization of the equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a milling device for complex inspection fixture parts and its processing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a milling device for complex inspection fixture parts and its processing technology, comprising a milling machine tool body; a movable base structure disposed at the bottom of the inner cavity of the milling machine tool body; and a milling auxiliary clamping fixture disposed at the top of the movable base structure. The milling auxiliary clamping fixture includes a base plate support, a hinge flipping component, a fixed frame, a flat-head vise, a hydraulic auxiliary flipping component, a flow cutter, a main drive component, and a lateral clamping and fixing component, wherein: the base plate support is fixedly installed on the top of the movable base structure; the hinge flipping component is disposed on the top of the base plate support, and one end of the hinge flipping component is fixedly installed with the fixed frame; the fixed frame is disposed on the top of the base plate support; and the flat-head vise is threaded to the side wall of the fixed frame. The device features a connection where the clamping part of the flat-head vise is located inside the square frame of the fixed frame. The two ends of the hydraulic auxiliary tilting component are movably connected between the base plate support and the fixed frame. The flow-cutting component is located on the hydraulic pipeline of the hydraulic auxiliary tilting component. The main drive component is positioned on the top of the base plate support, and its movable end is fixedly installed to one side of the bottom of the hinged tilting component. The lateral clamping fixing component is positioned on the top of the base plate support, and its clamping end abuts against the side wall of the fixed frame. This device enables automatic workpiece tilting during processing, eliminating the need for machine stoppage, disassembly, manual repositioning, and secondary clamping and positioning. This significantly reduces non-processing auxiliary time, making milling operations more seamless and improving overall milling speed and equipment utilization. Furthermore, the device's tilting structure employs a multi-point support design, avoiding structural damage issues that easily occur with traditional single-point supports during long-term reciprocating use, and significantly improving the operational stability and structural lifespan of the tilting mechanism. In addition, the central shaft of the device's flipping structure adopts a dedicated motion trajectory adapted to the flipping action. In the early stage of flipping, it can assist in lifting the workpiece, effectively overcoming the gravitational resistance torque in the initial flipping stage of the workpiece and reducing the driving load. At the rear end of the flipping, it can achieve damped descent, avoiding rigid impact when the workpiece is in place. This improves processing efficiency while ensuring workpiece positioning accuracy and equipment operation safety.

[0005] In some embodiments, the base plate support includes a main body, a plurality of main support rods, a plurality of main support seats, and two sets of symmetrically arranged limiting slide rails, wherein: the plurality of main support rods are all fixedly installed on the top of the main body, the plurality of main support seats are all fixedly installed on the top of the main body, and the two sets of symmetrically arranged limiting slide rails are all fixedly installed on the top of the main body.

[0006] In some embodiments, the hinge flipping component includes several fixed seats, several flipping seats, several sets of flipping rod one, several flipping rod two, several movable shaft one, several movable shaft two, and several central shafts. Specifically: several fixed seats are fixedly installed on the top of the main body; several flipping seats are fixedly installed to the end of the side wall of the fixed frame; one end of each set of flipping rod one is rotatably connected to a corresponding movable shaft one, and the other end of each set of flipping rod one is rotatably connected to the inner wall of the corresponding flipping seat; one end of each set of flipping rod two is rotatably connected to a corresponding movable shaft two, and the other end of each set of flipping rod two is rotatably connected to the inner wall of the corresponding fixed seat; each adjacent set of flipping rod one... The rotating rod and the second rotating rod are rotatably connected to the corresponding central shaft. When the first rotating shaft moves toward the second rotating shaft, the second rotating shaft moves synchronously toward the first rotating shaft. At the same time, the first rotating rod rotates around the shaft on the side wall of the rotating seat, and the second rotating rod rotates around the shaft on the side wall of the fixed seat. This causes the second rotating rod to rotate the fixed frame and the workpiece inside the fixed frame to the top area of ​​the fixed seat through the rotating seat, thereby changing the upper and lower sides of the workpiece. This allows the milling drill bit to perform milling operations on both the upper and lower sides of the workpiece in a single processing cycle, thus eliminating the tedious work of stopping, manually rotating, and re-fixing. This reduces the time of workpiece milling operations to a certain extent, thereby improving the processing speed of this milling device.

[0007] In some embodiments, the flat-head pliers include a lead screw, a flat-head clamp, and a screw head. The lead screw is threaded to the side wall of the fixed frame. The flat-head clamp is rotatably connected to one end of the lead screw. The screw head is fixedly installed on the end of the lead screw away from the flat-head clamp. The worker manually screws the screw head, which drives the lead screw to rotate, thereby causing the flat-head clamp to abut against the side wall of the workpiece, thus fixing the workpiece inside the fixed frame and completing the necessary preparations before processing.

[0008] In some embodiments, the hydraulic auxiliary tilting component includes several support slide rails, several movable vertical plates, several piston rods, several sleeves, an infusion tube, two telescopic rods, and several push wheels. Specifically: several support slide rails are fixedly installed on the top of the main body; several movable vertical plates are slidably disposed on the side walls of their respective support slide rails; several piston rods are welded to the side walls of their respective movable vertical plates; several sleeves are fixedly installed on the top of the main support base, and several piston plates are slidably disposed within the inner cavities of their respective sleeves; the bottoms of the two telescopic rods are rotatably connected to the side walls of the main body, and the tops of the two telescopic rods are respectively connected to the two end side walls of the fixed frame; the infusion tube is connected to several sleeves and two telescopic rods; and several push wheels are located on the rods of their respective central shafts.

[0009] In some embodiments, the flow-blocking component includes two flow-blocking cylinders, two flow-blocking plates, four flow-blocking rods, four flow-blocking plug plates, and four flow-blocking springs. The two flow-blocking cylinders are respectively mounted on corresponding infusion tubes; the two flow-blocking plates are respectively fixedly installed in the inner cavities of the corresponding flow-blocking cylinders; the four flow-blocking rods are respectively slidably mounted on the corresponding flow-blocking plates; the four flow-blocking plug plates are respectively fixedly installed at the bottom of the corresponding flow-blocking rods; and the four flow-blocking springs are respectively connected between the corresponding flow-blocking plug plates and the cavity walls of the corresponding flow-blocking cylinders. A central shaft drives a pusher to move along the trajectory of a support slide rail. The support slide rail further supports the central shaft, which experiences greater stress, thus ensuring the stability of the device during rotation. Observing the trajectory of the support slide rail, it can be seen that the pusher, following the central shaft's horizontal movement, first accelerates towards the rotation seat, then decelerates, and finally slowly returns to its original position a certain distance. The pusher can push the movable vertical plate and piston rod to move synchronously in the horizontal direction. During this process, the piston rod first accelerates towards the inside of the sleeve, allowing the liquid inside the sleeve to flow through the infusion tube. The fluid flows into the telescopic rod cavity, causing the telescopic rod to extend rapidly. This addresses the issue of maximum gravitational resistance torque during the initial flat placement, ensuring the main drive motor's output power remains within a relatively comfortable range and reducing the probability of damage caused by large fluctuations in output power. Once the workpiece is "pried" away from its stationary state, the gravitational resistance torque decreases significantly. The decelerating piston rod then matches this change in gravitational resistance torque, improving the smoothness of the flipping process. When the workpiece flips more than 90 degrees, the fixed frame pushes the telescopic rod inward, causing the liquid inside the telescopic rod cavity to flow in the opposite direction into the sleeve. During this process, the reverse-flowing liquid pushes the flow-blocking plate, blocking the auxiliary flow holes on both sides of the flow-blocking plate, narrowing the pipe cross-section during reverse flow and reducing the reverse flow rate, achieving a "damping" effect. This effect, when applied to the fixed frame, effectively reduces the problem of excessive speed due to gravity after the fixed frame flips more than 90 degrees, ensuring a stable overall flipping speed and preventing impacts caused by excessive speed, thus maximizing the protection of the device structure from damage.

[0010] In some embodiments, the main drive component includes a main drive motor, a second lead screw, a displacement block, and a drive frame. The main drive motor is fixedly mounted on the side wall of one of the main support seats. The second lead screw is fixedly mounted on the output end of the main drive motor. The displacement block is threaded onto the rod of the second lead screw. The drive frame is fixedly mounted on the top of the displacement block, and its side wall is fixedly mounted to the side wall of several movable shafts. The main drive motor drives the second lead screw to rotate, the second lead screw drives the displacement block to move, the displacement block drives the drive frame to move, and the drive frame synchronously drives the three movable shafts to move.

[0011] In some embodiments, the lateral clamping fixing component includes two clamping motors, two bidirectional lead screws, and four clamping inclined plates. The two clamping motors are fixedly mounted on the side wall of the main body. The two bidirectional lead screws are respectively fixedly mounted on the output ends of the corresponding clamping motors. Each pair of adjacent clamping inclined plates is threaded onto the corresponding bidirectional lead screw body, and each pair of adjacent clamping inclined plates is slidably mounted on a corresponding slide rail. The clamping motors drive the bidirectional lead screws to rotate, and the bidirectional lead screws drive the two symmetrically placed clamping inclined plates to move towards each other, causing the clamping inclined plates to abut against the side wall of the fixed frame, thereby completing the clamping and fixing of the fixed frame and maintaining the stability of the workpiece milling.

[0012] This invention provides a milling device for complex inspection fixture parts and its processing technology, which has the following beneficial effects: This complex inspection fixture parts milling device and its processing technology enable automatic workpiece flipping during processing, eliminating the need for machine stoppage, disassembly, manual repositioning, and secondary clamping and positioning. This significantly reduces non-processing auxiliary time, making milling operations more seamless and improving overall milling speed and equipment utilization. Furthermore, the device's flipping structure employs a multi-point support design, avoiding structural damage issues that easily occur with traditional single-point supports during long-term reciprocating use, thus significantly improving the operational stability and structural lifespan of the flipping mechanism. In addition, the central shaft of the flipping structure uses a dedicated motion trajectory adapted to the flipping action. In the initial flipping phase, it provides auxiliary lifting for the workpiece, effectively overcoming the gravitational resistance torque during the initial flipping stage and reducing the drive load. At the rear of the flip, it achieves damped descent, preventing rigid impact when the workpiece reaches its final position. This improves processing efficiency while ensuring workpiece positioning accuracy and equipment operational safety. Attached Figure Description

Detailed Implementation

[0016] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] Example 1: This application provides a milling device for complex inspection fixture parts and its processing technology, including: a milling machine tool body 100; a movable base structure 200 disposed at the bottom of the inner cavity of the milling machine tool body 100; and a milling auxiliary clamping fixture 300 disposed at the top of the movable base structure 200. The milling auxiliary clamping fixture 300 includes a base plate support 310, a hinge flipping component 320, a fixed frame 330, a flat-head vise 340, a hydraulic auxiliary flipping component 350, a flow cutter 360, a main drive component 370, and a lateral clamping fixing component 380, wherein: the base plate support 310 is fixedly installed on the top of the movable base structure 200; the hinge... A hinge flipper 320 is disposed on the top of the base plate support 310, and one end of the hinge flipper 320 is fixedly installed to the fixed frame 330; the fixed frame 330 is disposed on the top of the base plate support 310; the flat-head pliers 340 are threadedly connected to the side wall of the fixed frame 330, and the clamping part of the flat-head pliers 340 is located inside the square frame of the fixed frame 330; the two ends of the hydraulic auxiliary flipper 350 are respectively movably connected between the base plate support 310 and the fixed frame 330; the flow cutter 360 is located on the hydraulic pipeline of the hydraulic auxiliary flipper 350; the main drive 370 is disposed on the top of the base plate support 310, and the main drive... The movable end of component 370 is fixedly installed on one side bottom of hinge flip component 320; the base plate support component 310 includes a main body 311, a plurality of main support rods 312, a plurality of main support seats, and two sets of symmetrically arranged limiting slide rails 313, wherein: the plurality of main support rods 312 are all fixedly installed on the top of the main body 311, the plurality of main support seats are all fixedly installed on the top of the main body 311, and the two sets of symmetrically arranged limiting slide rails 313 are all fixedly installed on the top of the main body 311; the lateral clamping fixing component 380 is disposed on the top of the base plate support component 310, and the clamping end of the lateral clamping fixing component 380 abuts against the side wall of the fixed frame 330. The flat-head pliers 340 includes a lead screw 341, a flat-head clamp 342, and a screw head 343. The lead screw 341 is threadedly connected to the side wall of the fixed frame 330. The flat-head clamp 342 is rotatably connected to one end of the lead screw 341. The screw head 343 is fixedly installed on the end of the lead screw 341 away from the flat-head clamp 342. In use, the workpiece is first placed inside the fixed frame 330. Then, the worker manually screws the screw head 343, which drives the lead screw 341 to rotate, thereby causing the flat-head clamp 342 to abut against the side wall of the workpiece, thus fixing the workpiece inside the fixed frame 330 and completing the necessary preparations before processing.The lateral clamping and fixing component 380 includes two clamping motors 381, two bidirectional lead screws 382, ​​and four clamping inclined plates 383. The two clamping motors 381 are fixedly mounted on the side wall of the main body 311. The two bidirectional lead screws 382 are respectively fixedly mounted on the output ends of the corresponding clamping motors 381. Each pair of adjacent clamping inclined plates 383 is threadedly connected to the corresponding bidirectional lead screw 382, ​​and each pair of adjacent clamping inclined plates 383 is slidably mounted on a corresponding slide rail. The clamping motors 381 drive the bidirectional lead screws 382 to rotate, and the bidirectional lead screws 382 drive the symmetrically placed clamping inclined plates 383 to move towards each other, causing the clamping inclined plates 383 to abut against the side wall of the fixed frame 330, thereby completing the clamping and fixing of the fixed frame 330 to maintain the stability of the workpiece milling. Subsequently, the spindle of the milling device removes the corresponding milling drill bit from the cutter head, and the movable milling drill bit... The upper surface of the workpiece is milled using the movable base structure 200. During this process, the main support rod 312 located at the bottom of the fixed frame 330 can fix the frame 330 for vertical support, which further improves the stability of the workpiece during milling. After the upper surface of the workpiece is milled, the clamping motor 381 reverses, thereby releasing the clamping plate 383 from the fixed frame 330. The main drive component 370 includes a main drive motor 371, a lead screw 372, a displacement block 373, and a drive frame 374. The main drive motor 371 is fixedly installed on the side wall of one of the main support seats. The lead screw 372 is fixedly installed at the output end of the main drive motor 371. The displacement block 373 is threadedly connected to the rod of the lead screw 372. The drive frame 374 is fixedly installed on the top of the displacement block 373, and the side wall of the drive frame 374 is fixedly installed on the side wall of several movable shafts 325. Example 2: The hinge flipping component 320 includes several fixed seats 321, several flipping seats 322, several sets of flipping rods 323, several sets of flipping rods 324, several sets of movable shafts 325, several sets of movable shafts 326, and several central shafts 327. Specifically: several fixed seats 321 are fixedly installed on the top of the main body 311; several flipping seats 322 are fixedly installed to the side wall end of the fixed frame 330; one end of each set of flipping rods 323 is rotatably connected to a corresponding movable shaft 325, and the other end of each set of flipping rods 323 is rotatably connected to the inner wall of the corresponding flipping seat 322. One end of each of the two sets of rotating rods 324 is rotatably connected to a corresponding movable shaft 326, and the other ends of several sets of rotating rods 324 are rotatably connected to the inner wall of the corresponding fixed seat 321. Each adjacent rotating rod 323 and rotating rod 324 is rotatably connected to a corresponding central shaft 327. Subsequently, the main drive motor 371 drives the lead screw 372 to rotate, the lead screw 372 drives the displacement block 373 to move, the displacement block 373 drives the drive frame 374 to move, and the drive frame 374 synchronously drives the three movable shafts 325 to move. When the movable shaft 325 moves towards the movable shaft 326, the rotation is completed. When the 26 direction moves, the second movable shaft 326 will move synchronously towards the first movable shaft 325. Simultaneously, the first flipping rod 323 rotates around the shaft on the side wall of the flipping seat 322, and the second flipping rod 324 rotates around the shaft on the side wall of the fixed seat 321. This causes the second flipping rod 324 to flip the fixed frame 330 and the workpiece inside the fixed frame 330 to the top area of ​​the fixed seat 321 via the flipping seat 322, thus reversing the upper and lower surfaces of the workpiece. This allows the milling drill bit to perform milling operations on both the upper and lower surfaces of the workpiece in a single machining operation, eliminating the tedious work of stopping, manually flipping, and re-fixing. This feature is definitely... This reduces the time required for workpiece milling operations to a certain extent, thereby increasing the processing speed of the milling device. In addition, the hinge flipping component 320 in this application has a multi-point support structure. Taking the flipping rod 323 as an example: when the fixed frame 330 and the workpiece are flipped, the two ends and the center point of the flipping rod 323 are respectively supported by the movable shaft 325, the central shaft 327, and the shaft connecting the flipping rod 323 to the inner cavity of the flipping seat 322. The three-point support provides better stability. Compared with single-axis flipping, this multi-point support structure allows it to maintain good stability during long-term use.The hydraulic auxiliary tilting component 350 includes several support slide rails 351, several movable vertical plates 352, several piston rods 353, several sleeves 354, infusion tubes 355, two telescopic rods 356, and several push wheels 357. Specifically: several support slide rails 351 are fixedly installed on the top of the main base 311; several movable vertical plates 352 are slidably disposed on the side walls of their respective support slide rails 351; several piston rods 353 are welded to the side walls of their respective movable vertical plates 352; several sleeves 354 are fixedly installed on the top of the main support base, and several piston plates are slidably disposed within the inner cavities of their respective sleeves 354; the bottoms of the two telescopic rods 356 are rotatably connected to the main base. On the side wall of 311, the tops of the two telescopic rods 356 are respectively connected to the two end side walls of the fixed frame 330. The infusion tube 355 is connected to several sleeves 354 and the two telescopic rods 356. Several push rollers 357 are respectively located on the rods of the corresponding central shaft 327. The flow-blocking component 360 includes two flow-blocking cylinders 361, two flow-blocking plates 362, four flow-blocking rods 363, four flow-blocking plug plates 364, and four flow-blocking springs 365. The two flow-blocking cylinders 361 are respectively set on the corresponding infusion tubes 355. The two flow-blocking plates 362 are respectively fixedly installed in the inner cavity of the corresponding flow-blocking cylinders 361. The four flow-blocking rods 363 are respectively slidably set on the corresponding flow-blocking plates 362. The flow-blocking plugs 364 are fixedly installed at the bottom of the corresponding flow-blocking rods 363, and the four flow-blocking springs 365 are respectively connected between the corresponding flow-blocking plugs 364 and the cavity walls of the corresponding flow-blocking cylinders 361. The central shaft 327 drives the pusher 357 to move along the trajectory of the support slide rail 351. The support slide rail 351 can further support the central shaft 327, which is subjected to greater force, thus further ensuring the stability of the device when it is flipped. Observing the trajectory of the support slide rail 351, it can be seen that the pusher 357 follows the central shaft 327 in the horizontal direction by first accelerating towards the flipping seat 322, then decelerating, and finally slowly returning to its original position a certain distance. The pusher 357 can push the movable... The vertical plate 352 and the piston rod 353 move synchronously in the horizontal direction. During this process, the piston rod 353 first accelerates and moves into the sleeve 354. Then, the liquid inside the sleeve 354 flows into the cavity of the telescopic rod 356 through the infusion pipe 355, which causes the telescopic rod 356 to extend rapidly. This solves the problem of the greatest gravitational resistance torque when the workpiece is initially placed flat, so that the output power of the main drive motor 371 is always maintained in a relatively comfortable range, reducing the probability of damage to the main drive motor 371 due to large fluctuations in output power. When the workpiece is "pried" away from the stationary state, the gravitational resistance torque is greatly reduced. The piston rod 353, which then decelerates, can match this gravitational resistance torque change process, thereby improving the smoothness of its flipping process.When the workpiece is rotated more than 90 degrees, the fixed frame 330 pushes the telescopic rod 356 inward. At this time, the liquid in the cavity of the telescopic rod 356 flows in the opposite direction into the sleeve 354. During this process, the reverse-flowing liquid pushes the flow-blocking plug 364 to block the auxiliary flow holes on both sides of the flow-blocking plate 362, narrowing the cross-section of the pipe during reverse flow and thus reducing the reverse flow rate, achieving a "damping" effect. When this effect acts on the fixed frame 330, it can effectively reduce the problem of the fixed frame 330 rotating too quickly due to gravity after rotating more than 90 degrees, thus ensuring a stable overall rotation speed and avoiding impact due to excessive speed, thereby maximizing the protection of the device structure from damage.

[0018] Working principle: In use, the workpiece is first placed inside the fixed frame 330. Then, the worker manually turns the screw head 343, which drives the lead screw 341 to rotate, thereby causing the flat head clamp 342 to abut against the side wall of the workpiece, thus fixing the workpiece inside the fixed frame 330 and completing the necessary preparations before processing. Then, the worker leaves the processing area of ​​the milling machine body 100 and closes the protective door of the milling machine body 100. Then, the milling device starts to work. First, the clamping motor 381 drives the bidirectional lead screw 382 to rotate. The bidirectional lead screw 382 drives two symmetrically placed clamping inclined plates 383 to move towards each other, so that the clamping inclined plates 383 abut against the side wall of the fixed frame 330, thereby completing the clamping and fixing of the fixed frame 330 and maintaining the stability of the workpiece milling. Then, the spindle of the milling device removes the corresponding milling drill bit from the cutter head, and the movable milling drill bit, in conjunction with the movable base structure 200, mills the upper surface of the workpiece. During the milling process, the main support rod 312 located at the bottom of the fixed frame 330 can fix the frame 330 for vertical support, which further improves the stability of the workpiece during milling. After the upper surface of the workpiece is milled, the clamping motor 381 reverses, thereby releasing the clamping plate 383 from the fixed frame 330. Subsequently, the main drive motor 371 drives the lead screw 372 to rotate, and the lead screw 372 drives the displacement block 373 to move. 373 drives the drive frame 374 to move, and the drive frame 374 simultaneously drives the three movable shafts 325 to move. When the first movable shaft 325 moves towards the second movable shaft 326, the second movable shaft 326 will move towards the first movable shaft 325 simultaneously. At the same time, the first flipping rod 323 rotates around the shaft on the side wall of the flipping seat 322, and the second flipping rod 324 rotates around the shaft on the side wall of the fixed seat 321, thereby causing the second flipping rod 324 to move through the flipping seat 322. 2. The fixed frame 330 and the workpiece inside the fixed frame 330 are rotated to the top area of ​​the fixed seat 321, thereby changing the upper and lower sides of the workpiece. This allows the milling drill bit to perform milling operations on both the upper and lower sides of the workpiece in a single processing cycle, thus eliminating the tedious work of stopping, manually rotating, and re-fixing. This reduces the time of workpiece milling operations to a certain extent, thereby improving the processing speed of this milling device. In addition, the hinge flipping component 320 in this application has the structural characteristics of multi-point support. Taking the flipping rod 323 as an example: when the fixed frame 330 and the workpiece are flipped, the two ends and the center point of the flipping rod 323 are respectively supported by the movable shaft 325, the central shaft 327, and the shaft connecting the flipping rod 323 to the inner cavity of the flipping seat 322. The three-point support provides good stability. Compared with single-axis flipping, this multi-point support structure can maintain good stability during long-term use. During the flipping process, the central shaft 327 drives the push wheel 357 to move along the trajectory of the support slide rail 351. The support slide rail 351 can further support the central shaft 327, which is subjected to more force, thus further ensuring the stability of the device during flipping. Observing the trajectory of the support slide rail 351, it can be seen that the push wheel 357, following the horizontal movement of the central shaft 327, first accelerates towards the tilting seat 322, then decelerates, and finally slowly returns to its original position a certain distance. The push wheel 357 can push the movable vertical plate 352 and the piston rod 353 to move synchronously in the horizontal direction. During this process, the piston rod 353 first accelerates towards the inside of the sleeve 354, and then the liquid inside the sleeve 354 flows through the infusion pipe 355 into the cavity of the telescopic rod 356, causing the telescopic rod 356 to extend rapidly. This solves the problem of the greatest gravitational resistance torque when initially placed flat, ensuring that the output power of the main drive motor 371 remains within a relatively comfortable range, reducing the probability of damage to the main drive motor 371 due to large fluctuations in output power. Once the workpiece is "pried" away from its stationary state... The gravitational resistance torque is significantly reduced, and the decelerating piston rod 353 can match this gravitational resistance torque change process, thereby improving the smoothness of its flipping process. When the workpiece flips more than 90 degrees, the fixed frame 330 pushes the telescopic rod 356 in the opposite direction to retract. At this time, the liquid in the cavity of the telescopic rod 356 flows in the opposite direction into the sleeve 354. During this process, the reverse-flowing liquid pushes the flow-blocking plug 364 to block the auxiliary flow holes on both sides of the flow-blocking plate 362, so that the pipe cross-section during reverse flow is narrowed, thereby reducing the reverse flow rate and achieving a "damping" effect. When this effect is applied to the fixed frame 330, it can effectively reduce the problem of the fixed frame 330 flipping more than 90 degrees due to the influence of gravity and thus ensure that the overall speed of its flipping process is stable, avoid impact due to excessive speed, and thus protect the device structure from damage to the maximum extent.
