Description

Technical Field

[0001] This invention relates to the field of cylinder block machining technology, and in particular to a cylinder block machining auxiliary flipping device and cylinder block machining process. Background Technology

[0002] As a core component of the engine, the cylinder block's machining accuracy directly determines the engine's overall performance. The machining process requires multiple key steps, including roughing and finishing, specifically encompassing planar milling, hole machining, and roughing of the crankshaft semi-circular hole. Each step requires machining different surfaces of the cylinder block, so the cylinder block needs to be rotated multiple times during the machining process. The core purpose of this rotation is to achieve precise switching between the various machined surfaces of the cylinder block, ensuring the smooth progress of each machining step and meeting the multi-directional machining needs of the cylinder block.

[0003] Current processing equipment suffers from numerous technical defects, making it difficult to meet the demands of high-precision mass production. Traditional clamping structures employ fixed-specification clamping plates, which cannot flexibly adapt to different cylinder models. Furthermore, the clamping plates are mostly rigid structures, failing to conform to the irregular outer walls of the cylinder. This leads to uneven force distribution and insufficient stability during clamping, causing cylinder wobbling during processing and easily resulting in scratches and wear on the outer walls of the cylinder, affecting subsequent workpiece assembly.

[0004] Meanwhile, the clamping and flipping structures lack effective linkage, and the debris removal method is mostly concentrated cleaning after machining, which cannot remove debris generated during machining in real time. In particular, residual debris in hidden locations such as channels and crankshaft semi-circular holes will interfere with subsequent machining positioning, aggravate tool wear, increase workpiece scrap rate and production costs, and result in low overall machining efficiency. Therefore, those skilled in the art provide a cylinder block machining auxiliary flipping device and cylinder block machining process to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a cylinder block machining auxiliary flipping device and cylinder block machining process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cylinder block machining auxiliary flipping device, comprising a main structure, a clamping structure, a flipping structure and a blowing structure, wherein the main structure comprises a machining frame, a support frame one and a support frame two, wherein the support frame one and the support frame two are symmetrically distributed on the inner walls of both sides of the machining frame; The clamping structure includes a stroke plate, a hydraulic rod, and a clamping plate. The stroke plates are symmetrically distributed between support frame one and support frame two. The clamping plates are arranged in a rectangular array on one side of the stroke plates. A screw is rotatably installed at one end of each clamping plate. A screw hole is opened inside the stroke plate, and the screw is threadedly inserted into the screw hole. The flipping structure includes a support rod, a second gear, a second hydraulic rod, and a toothed plate. The flipping structure adjusts the rotation of the clamping stroke plate. The blowing structure is located behind the clamping structure. The blowing structure is used to blow away debris from the outer wall of the cylinder held by the clamping structure before it is turned over and to remove it by airflow during the processing.

[0007] Preferably, the outer wall of one end of the screw is provided with rotating rods arranged in a ring array, and each of the four corners of the clamping plate is provided with a rotating groove, and a clamping block that rotates clockwise and counterclockwise inside the rotating groove.

[0008] Preferably, the first clamping plate has symmetrically distributed second rotating grooves located between the first rotating grooves, and the second rotating groove has an axially rotating clamping block installed inside it. The clamping ends of the first clamping block and the second clamping block are both horizontal, and the clamping surfaces of the first clamping block and the second clamping block are both provided with rubber pads.

[0009] Preferably, gear one and gear two are respectively sleeved on the outer walls of the two sets of support rods, and a rotating seat is provided at one end of each support rod. The hydraulic rods are symmetrically distributed and fixed inside the support frame one and support frame two. A rotating block is provided at the telescopic end of the hydraulic rod one and is rotatably installed inside the rotating seat.

[0010] Preferably, four sets of guide rods are slidably installed inside both the first support frame and the second support frame. The opposite ends of the guide rods are connected to the first support frame and the second support frame, respectively. One end of the first support frame is provided with a hydraulic rod 2. The telescopic end of the hydraulic rod 2 is provided with a connecting block. One end of the connecting block is provided with a toothed plate, which meshes with a gear 1.

[0011] Preferably, one end of the support frame is provided with a guide rail, the upper end of the gear plate is provided with a sliding groove that is slidably sleeved on the outer wall of the guide rail, and a retaining tooth is installed in the upper tooth groove of the gear.

[0012] Preferably, a fixing block is provided at the upper end of the locking tooth, a torsion spring is provided at one end of the fixing block, a positioning block is provided at one end of the torsion spring and connected to the second support frame, and a torsion shaft is provided at one end of the fixing block, which is located inside the torsion spring and rotatably installed inside the positioning block.

[0013] Preferably, the purging structure includes a hydraulic rod three, a mounting frame, a cylinder and a motor. The rear end of the processing frame is provided with a rear support plate for fixing the hydraulic rod three. The telescopic end of the hydraulic rod three is connected to the mounting frame. One end of the mounting frame is provided with symmetrically distributed bearing seats. Both ends of the cylinder are provided with support tubes rotatably mounted inside the bearing seats, one of which is closed at one end.

[0014] Preferably, an inner bearing is embedded inside one end of the support tube, an airflow pipe is rotatably installed inside the inner bearing, a purge hole arranged in a ring array is opened on the outer wall of the cylinder, the airflow pipe is connected to and delivers high-pressure airflow through a high-pressure air pump, and brush strips arranged in a ring array are provided on the outer wall of the cylinder.

[0015] A cylinder block machining process, the steps of which are as follows: S1: During cylinder machining, the cylinder is clamped between the stroke plates. The stroke plates move relative to the cylinder according to its specifications, driven by hydraulic rod one. The screw screws into the screw hole to adjust the position of the clamping plate. The cylinder is clamped at multiple points according to its shape. The entire cylinder is clamped at both ends by hydraulic rod one. During the cylinder clamping process, clamping blocks one and two adaptively rotate and adjust themselves through their different rotation directions, fitting against the irregular outer wall of the cylinder. This achieves multi-point and multi-dimensional adaptive clamping of the cylinder, improving stability and reducing friction during cylinder machining, thus preventing damage to the outer wall of the cylinder during clamping. S2: The clamping structure and the flipping structure are linked. Under the premise that the clamping structure clamps the cylinder body, the rotating block and the rotating seat are used as the rotation base. The hydraulic rod two is used as the driving force to drive the tooth plate to move. Through the meshing of the tooth plate and the gear two, the support rod is driven to rotate and the stroke plate is driven to flip, so as to achieve stable reverse rotation of different surfaces of the cylinder body. During the flipping process, one of the stroke plates is connected by the cylinder body being clamped and the stroke is stable. It is supported by rotation without the driving component and without the rotation support through the rotating component (the rotating block and the rotating seat and the support rod on one side of the support frame two). The other support rod used for rotation is maintained stable under the condition of no force through the meshing of the torsional elastic support tooth and the gear one. This prevents the stroke plate from rotating arbitrarily through the rotating component when it moves during the cylinder body clamping process. S3: The airflow pipe continuously delivers airflow into the cylinder body and acts on the cylinder body through the purging hole, causing real-time debris generated during machining to detach. When the cylinder body is rotated, the hydraulic rod three-drive mounting frame moves, causing the mounting frame to move the cylinder body towards the cylinder body. At this time, the motor drives the support pipe to rotate, which in turn drives the cylinder body to rotate. The cylinder body drives the brush strip to brush the outer wall of the cylinder body. Combined with the purging hole, the stubborn debris that is hidden in the irregular parts of the cylinder body is blown off by the airflow and physically scraped off. The debris enters the machining frame for collection. The machining frame is located below the cylinder body. The debris and coolant that fall naturally during the machining process are collected. The debris generated by different surfaces and holes of the cylinder body, plane milling, rough machining of crankshaft semi-circular holes, etc. are effectively treated to avoid residual debris affecting the accuracy of subsequent machining.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention's clamping mechanism utilizes a hydraulically driven stroke plate to adapt to cylinders of different specifications. The screw adjusts the clamping plate position, and clamping blocks one and two adaptively rotate to fit against irregular outer walls, achieving multi-point, multi-dimensional clamping. This enhances machining stability, reduces clamping friction, and completely prevents damage to the cylinder's outer wall. The flipping and clamping structures are linked, with hydraulically driven toothed plates achieving smooth flipping. Torsional elastic support teeth maintain stability when one set of stroke plates is not driven, ensuring no shaking during machining of different cylinder surfaces and guaranteeing machining positioning accuracy. The debris removal process uses a continuous airflow pipe. During flipping, the cylinder rotates, causing brushes to scrape, and combined with the collection from the machining frame, efficiently removing debris generated during hole machining, planar milling, and other processes. This prevents residual debris from affecting subsequent positioning and machining accuracy, reduces the burden of the cleaning process, decreases tool wear and workpiece scrap rate, and overall improves machining continuity and finished product yield.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 The present invention provides four embodiments: Example 1: A cylinder block machining auxiliary flipping device includes a main structure 100, a clamping structure 200, a flipping structure 300 and a blowing structure 400. The main structure 100 includes a machining frame 101, a first support frame 102 and a second support frame 103. The first support frame 102 and the second support frame 103 are symmetrically distributed on the inner walls of both sides of the machining frame 101. The clamping structure 200 includes a stroke plate 201, a hydraulic rod 203, and a clamping plate 205. The stroke plate 201 is symmetrically distributed between the support frame 102 and the support frame 203. The clamping plate 205 is arranged in a rectangular array on one side of the stroke plate 201. A screw 204 is rotatably installed at one end of the clamping plate 205. A screw hole 207 is opened inside the stroke plate 201. The screw 204 is threadedly inserted into the screw hole 207. The flipping structure 300 includes a support rod 303, a second gear 310, a second hydraulic rod 311, and a toothed plate 312. The flipping structure 300 adjusts the rotation of the clamping stroke plate 201. The blowing structure 400 is located behind the clamping structure 200. The blowing structure 400 is used to blow away the cylinder outer wall debris held by the clamping structure 200 before flipping it over and to remove it by airflow during the processing.

[0021] The outer wall of one end of the screw 204 is provided with rotating rods 206 arranged in a ring array, and the four corners of the clamping plate 205 are provided with rotating grooves 208, and the clamping blocks 209 inside the rotating grooves 208 rotate clockwise and counterclockwise.

[0022] The clamping plate 205 has a symmetrically distributed rotating groove 210 located between the rotating grooves 208. The rotating groove 210 has an axially rotating clamping block 211. The clamping ends of the clamping blocks 209 and 211 are both horizontal, and the clamping surfaces of the clamping blocks 209 and 211 are provided with rubber pads.

[0023] In this embodiment, the auxiliary device and supporting processing technology for cylinder block machining solve the problems of inflexible clamping, unstable flipping, and untimely debris removal during existing cylinder block machining. It is suitable for batch high-precision machining, practical, and easy to operate. This device mainly consists of four parts: a main body, clamping, flipping, and blowing. The main body includes a machining frame 101 and two symmetrical support frames. The support frames are used to install other components, while the machining frame 101 collects debris and coolant generated during machining to prevent contamination. The clamping part is the core, consisting of a stroke plate 201, a hydraulic rod 203, a clamping plate 205, a screw 204, and two types of clamping blocks. The hydraulic rod 203 can move the stroke plate 201 to initially adjust the clamping distance, while the screw 204 can fine-tune the position of the clamping plate 205 to adapt to cylinder blocks of different sizes. The clamping blocks at the four corners and center of clamping plate 205 can rotate flexibly and automatically conform to the irregular outer wall of the cylinder. The surface of the clamping blocks also has rubber pads to prevent scratching the cylinder and to firmly clamp the cylinder. Example 1 mainly describes this clamping structure 200. Its working principle is very simple: hydraulic rod 203 drives the stroke plate 201 to move, screw 204 finely adjusts clamping plate 205, and the clamping blocks automatically conform to the cylinder to achieve stable clamping. The operation process is also not complicated. After the cylinder is put on the line, first adjust the stroke plate 201 to determine the approximate clamping range, then use screw 204 to finely adjust, and finally drive the stroke plate 201 to clamp the cylinder, and then proceed to the next process.

[0024] The advantages of this clamping method are that it can adapt to cylinders of different specifications, eliminating the need for frequent component replacements. It provides even force during clamping, preventing wobbling and scratching of the cylinder, thus improving processing efficiency, reducing scrap, and lowering costs. It solves the problems of poor adaptability, easy cylinder scratching, and unstable clamping associated with traditional fixed clamping plates 205. The flipping section includes components such as a support rod 303, gears, a second hydraulic rod 311, and a toothed plate 312. The second hydraulic rod 311 drives the toothed plate 312 to move, which in turn drives the gears and support rod 303 to rotate, thereby causing the stroke plate 201 and the cylinder to flip, facilitating the processing of different surfaces of the cylinder. Additionally, the clamping teeth 305 and torsion spring 308 provide limiting mechanisms, preventing arbitrary rotation without driving force and ensuring smooth flipping.

[0025] The purging section consists of a hydraulic rod 401, a cylinder 407, a motor 410, and an airflow pipe 406. The airflow pipe 406 continuously blows air to remove loose debris from the cylinder. When the cylinder is rotated, the hydraulic rod 401 moves the cylinder 407 closer to the cylinder, and the motor 410 rotates the cylinder 407. The brush strips 409 on the cylinder 407 wipe away stubborn debris, and the debris and coolant fall into the machining frame 101 below. The corresponding machining process consists of three steps: first, the cylinder is clamped by the clamping structure 200; second, the cylinder is rotated by the rotating structure 300 to switch the machining surface; and third, the debris is cleaned by the purging structure 400, forming a complete machining process.

[0026] With clear advantages, it offers flexible clamping, smooth tilting, and timely debris removal, integrating these three functions without the need for additional equipment. This simplifies the processing flow, reduces production costs, and makes it suitable for mass production. Its protection scope covers both the device and the processing technology. All components are common hydraulic systems, gears, and 410 motors, making processing relatively simple and allowing direct integration into existing production lines without large-scale modifications. Compared to similar technologies, it effectively solves the linkage problem between clamping, tilting, and cleaning, making it more suitable for the entire cylinder block processing process than simple cleaning devices. Furthermore, it is adaptable to the processing of small and medium-sized cylinder blocks, such as engine and compressor blocks, saving production line space. The rotation angle of the clamping blocks and the pressure of the hydraulic rods can also be adjusted according to the cylinder block specifications, making it more flexible to use.

[0027] Example 2: Two sets of support rods 303 are respectively fitted with gear 304 and gear 310 on their outer walls. Each support rod 303 has a rotating seat 301 at one end. Hydraulic rods 203 are symmetrically distributed and fixed inside support frame 102 and support frame 203. The telescopic end of hydraulic rod 203 is provided with a rotating block 302 that is rotatably installed inside the rotating seat 301.

[0028] Four sets of guide rods 202 are slidably installed inside both support frame 102 and support frame 203. The opposite ends of the guide rods 202 are connected to support frame 102 and support frame 203 respectively. One end of support frame 102 is provided with hydraulic rod 2 311. The telescopic end of hydraulic rod 2 311 is provided with connecting block 315. One end of connecting block 315 is provided with toothed plate 312, which meshes with gear 1 304.

[0029] One end of the support frame 102 is provided with a guide rail 313, and the upper end of the toothed plate 312 is provided with a sliding groove 314 that is slidably sleeved on the outer wall of the guide rail 313. The upper tooth groove of the gear 2 310 is fitted with a retaining tooth 305.

[0030] A fixing block 306 is provided at the upper end of the locking tooth 305. A torsion spring 308 is provided at one end of the fixing block 306. A positioning block 309 is provided at one end of the torsion spring 308 and connected to the support frame 103. A torsion shaft 307 is provided at one end of the fixing block 306, which is located inside the torsion spring 308 and rotatably installed inside the positioning block 309.

[0031] In this embodiment, the clamping part is the core, which includes a stroke plate 201, a hydraulic rod 203, a clamping plate 205, a screw 204, and two types of clamping blocks. The hydraulic rod 203 can drive the stroke plate 201 to move and initially adjust the clamping distance. The screw 204 can finely adjust the position of the clamping plate 205 to adapt to cylinders of different sizes. The clamping blocks at the four corners and the middle of the clamping plate 205 can rotate flexibly and can automatically fit when they encounter the irregular outer wall of the cylinder. The surface of the clamping blocks also has rubber pads to prevent scratching the cylinder and to firmly clamp the cylinder.

[0032] Hydraulic rod 203 drives the stroke plate 201 to move, screw 204 fine-tunes the clamping plate 205, and the clamping blocks automatically fit into the cylinder body for stable clamping. The operation process is also simple: after the cylinder body is on the line, first adjust the stroke plate 201 to determine the approximate clamping range, then use screw 204 for fine-tuning, and finally drive the stroke plate 201 to clamp the cylinder body, allowing it to proceed to subsequent processes. The advantages of this clamping method are that it can adapt to cylinder bodies of different specifications, eliminating the need for frequent component replacements. The force is evenly distributed during clamping, preventing wobbling and scratching of the cylinder body. This improves processing efficiency, reduces scrap, lowers costs, and solves the problems of poor adaptability, easy scratching of the cylinder body, and unstable clamping associated with traditional fixed clamping plates 205. The flipping section includes components such as support rod 303, gear, hydraulic rod 311, and toothed plate 312. Hydraulic rod 311 drives toothed plate 312 to move, and toothed plate 312 drives gear and support rod 303 to rotate, thereby driving stroke plate 201 and cylinder to flip, which facilitates the processing of different surfaces of cylinder. At the same time, there are also retaining teeth 305 and torsion spring 308 for limiting, so it will not rotate randomly when there is no driving force, and the flipping is very stable.

[0033] Two sets of support rods 303 are fitted with gear 1 304 and gear 2 310 respectively. Each support rod 303 has a rotating seat 301 at one end. Hydraulic rod 1 203 is fixed inside the two support frames. The rotating block 302 at its telescopic end is installed in the rotating seat 301 and can rotate flexibly. Each of the two support frames is equipped with four sets of guide rods 202 to maintain structural stability. Hydraulic rod 2 311 at one end of support frame 1 102 can drive the connecting block 315 and the toothed plate 312 to move. The toothed plate 312 meshes with gear 1 304. The sliding groove 314 at the upper end of the toothed plate 312 is fitted on the guide rail 313 for smoother movement. Gear 2 310 has a locking tooth 305 at its upper end. The locking tooth 305 is connected to support frame 2 103 through a fixing block 306, a torsion spring 308 and a positioning block 309. The torsion shaft 307 passes through the torsion spring 308 and allows the locking tooth 305 to rotate flexibly.

[0034] After the cylinder body is clamped and stabilized, the hydraulic rod 311 is activated, causing the gear plate 312 to slide along the guide rail 313. The gear plate 312 drives the gear 304 to rotate, which in turn causes the support rod 303 and the stroke plate 201 to flip, realizing the switching of different surfaces of the cylinder body. During the flipping, the locking teeth 305 on the other set of support rods 303 are locked onto the gear 310 under the action of the torsion spring 308, which plays a limiting role. Without driving force, the cylinder body will not rotate arbitrarily. The advantages of this flipping method are that it is stable and does not shake during the flipping, which can ensure the machining accuracy of the cylinder body. The structure is simple, and the parts used are common gears, hydraulic rods, etc., which are not complicated to process and install, and do not require additional complex equipment. It can be well linked with the clamping structure 200, and the cylinder body will not loosen or shift during the flipping process.

[0035] This design solves the problems of poor linkage, instability during rotation, lack of reliable limit switches, and easy random rotation in existing 300-type tilting structures, which affect machining accuracy. It can also adapt to the tilting requirements of cylinders of different specifications, is easy to operate, and can improve machining efficiency. The purging part consists of a hydraulic rod 401, a cylinder 407, a motor 410, and an airflow pipe 406. The airflow pipe 406 continuously blows air to remove floating debris from the cylinder. When the cylinder is tilted, the hydraulic rod 401 moves the cylinder 407 closer to the cylinder, and the motor 410 drives the cylinder 407 to rotate. The brush strips 409 on the cylinder 407 can wipe away stubborn debris. The debris and coolant will fall into the machining frame 101 below. The supporting processing technology consists of three steps. The first step is to clamp the cylinder body with the clamping structure 200. The second step is to flip the cylinder body with the flipping structure 300 to switch the processing surface. The third step is to clean the debris with the blowing structure 400, forming a complete processing flow. The clamping is flexible, the flipping is stable, and the debris is cleaned in time. The three functions are integrated together without the need for additional equipment, which can simplify the processing flow and reduce production costs.

[0036] Example 3: The purging structure 400 includes a hydraulic rod 401, a mounting frame 403, a cylinder 407, and a motor 410. The rear end of the processing frame 101 is provided with a rear support plate 402 for fixing the hydraulic rod 401. The telescopic end of the hydraulic rod 401 is connected to the mounting frame 403. One end of the mounting frame 403 is provided with symmetrically distributed bearing seats 404. Both ends of the cylinder 407 are provided with support tubes rotatably mounted inside the bearing seats 404, one of which is closed at one end.

[0037] An inner bearing 405 is embedded inside one end of the support tube. An airflow pipe 406 is rotatably installed inside the inner bearing 405. The outer wall of the cylinder 407 has purge holes 408 arranged in a ring array. The airflow pipe 406 is connected to and delivers high-pressure airflow through a high-pressure air pump. The outer wall of the cylinder 407 is provided with brush strips 409 arranged in a ring array.

[0038] In this embodiment, the purging structure 400 includes a hydraulic rod 401, a mounting frame 403, a cylinder 407, and a motor 410. The rear support plate 402 at the rear end of the processing frame 101 is used to fix the hydraulic rod 401. The telescopic end of the hydraulic rod 401 is connected to the mounting frame 403. One end of the mounting frame 403 has symmetrical bearing seats 404. The support tubes at both ends of the cylinder 407 are rotatably installed in the bearing seats 404, and one end of one of the support tubes is closed. One end of the support tube is equipped with an inner bearing 405. The airflow pipe 406 is rotatably installed in the inner bearing 405. The airflow pipe 406 is connected through a high-pressure air pump and can deliver high-pressure airflow. The outer wall of the cylinder 407 has an annular array of purging holes 408 and brush strips 409.

[0039] Its operation process is not complicated. During the cylinder processing and flipping process, the airflow pipe 406 continuously delivers high-pressure airflow, which is blown onto the cylinder through the blow-out hole 408 to blow away the floating debris. When the cylinder flips, the hydraulic rod 401 is activated, which drives the mounting frame 403 and the cylinder 407 to approach the cylinder. Then the motor 410 is activated, which drives the support pipe and the cylinder 407 to rotate. The brush strip 409 on the cylinder 407 will scrape the stubborn debris on the irregular parts of the cylinder. With the airflow from the blow-out hole 408, the debris is thoroughly cleaned. The cleaned debris and coolant will fall into the processing frame 101 below.

[0040] The advantages of this purging method are that it can clean up debris in real time, removing both loose and stubborn debris without waiting for the end of processing. This avoids debris residue affecting the accuracy of subsequent processing, reduces tool wear, lowers the scrap rate, and features a simple structure and convenient operation without the need for additional complex equipment. It solves the problems of untimely debris removal and stubborn debris not being removed, which affect processing accuracy and accelerate tool wear. It can be well linked with the clamping and flipping structure 300 to ensure a smooth processing flow. The purging part consists of hydraulic rod 401, cylinder 407, motor 410, and airflow pipe 406. The airflow pipe 406 continuously blows air to remove loose debris from the cylinder. When the cylinder flips, hydraulic rod 401 moves cylinder 407 closer to the cylinder, and motor 410 rotates cylinder 407. The brush strips 409 on cylinder 407 wipe away stubborn debris, and the debris and coolant fall into the processing frame 101 below. The cylinder body is clamped by the clamping structure 200 and flipped by the flipping structure 300 to switch the machining surface. The blowing structure 400 cleans up the debris, forming a complete machining process.

[0041] Example 4: A cylinder block machining process, the steps of which are as follows: S1: During cylinder machining, the cylinder is clamped between stroke plates 201. The stroke plates 201 move relative to the cylinder according to its specifications, driven by hydraulic rod 203. The screw 204 screws into the screw hole 207 to adjust the position of the clamping plate 205. The cylinder is clamped at multiple points according to its shape. The cylinder is clamped at both ends by hydraulic rod 203. During the cylinder clamping process, clamping blocks 209 and 211 adjust their rotation according to their different rotation directions and fit against the irregular outer wall of the cylinder. This achieves multi-point and multi-dimensional adaptive clamping of the cylinder, improving stability and reducing friction during cylinder machining, thus preventing damage to the outer wall of the cylinder during clamping. S2: The clamping structure 200 and the flipping structure 300 are linked. Under the premise that the clamping structure 200 clamps the cylinder, the rotating block 302 and the rotating seat 301 are used as the rotation base. The hydraulic rod 311 is used as the driving force to drive the toothed plate 312 to move. Through the meshing of the toothed plate 312 and the gear 310, the support rod 303 is driven to rotate, and the stroke plate 201 is driven to flip, so as to realize the stable reverse rotation of different surfaces of the cylinder. During the flipping process, one of the stroke plates 201 is connected with the cylinder being clamped and the stroke is stable. It is rotated without the driving component and without the rotation support through the rotating component (the rotating block 302 and the rotating seat 301 and the support rod 303 on one side of the support frame 103). The other support rod 303 for rotation is maintained stable without force through the meshing of the torsional elastic support tooth 305 and the gear 304. This prevents the stroke plate 201 from rotating arbitrarily through the rotating component when it moves during the cylinder clamping process. S3: The airflow pipe 406 continuously delivers airflow into the cylinder 407 and acts on the cylinder body through the blow-out hole 408, causing the real-time debris generated during machining on the cylinder body to detach. When the cylinder body is rotated, the hydraulic rod 401 drives the mounting frame 403 to move, causing the mounting frame 403 to move the cylinder body 407 toward the cylinder body. At this time, the motor 410 drives the support pipe to rotate, and drives the cylinder body 407 to rotate. The cylinder body 407 drives the brush strip 409 to brush the outer wall of the cylinder body. With the help of the blow-out hole 408, the stubborn debris that is hidden in the irregular parts of the cylinder body is blown off by the airflow and physically scraped off. The debris enters the machining frame 101 for collection. The machining frame 101 is located below the cylinder body. The debris and coolant that fall naturally during the machining process are collected. The debris generated by the machining of different surfaces and holes of the cylinder body, plane milling, rough machining of the crankshaft semi-circular hole, etc. are effectively treated to avoid residual debris affecting the subsequent machining accuracy.
