Description

Technical Field

[0001] This invention relates to the field of compressor cylinder processing technology, and in particular to a modular processing unit of a continuous compressor cylinder processing production line. Background Technology

[0002] A compressor cylinder is a component that is fastened to the compressor body or crankcase and works with the piston to compress gas. Different models of compressor cylinders have significant structural differences, but generally they all include various holes and grooves distributed on two end faces and the outer peripheral wall. Different holes and grooves require different equipment for machining. After machining some holes or grooves on one machine, the compressor cylinder needs to be transferred to another machine to machine the remaining holes or grooves. Currently, there is no consistency or linkage between different machining equipment, making it difficult to form an automated production line for compressor cylinder machining, resulting in low machining efficiency. Summary of the Invention

[0003] In view of this, the present invention proposes a modular processing unit for a continuous processing production line for compressor cylinders, which can at least partially solve the above-mentioned technical problems.

[0004] The technical solution of this invention is implemented as follows:

[0005] A modular processing unit for a continuous machining production line for compressor cylinders includes:

[0006] A rotary machining table includes a base, on which a worktable is rotatably mounted about a vertical axis. A conveying docking station and a processing docking station are symmetrically arranged on the upper surface of the worktable about the vertical axis. Clamping mechanisms are respectively provided on the conveying docking station and the processing docking station, and the clamping mechanisms are equipped with multiple clamps for fixing compressor cylinders.

[0007] A machining center is located above the machining docking station to machine the compressor cylinder on the clamping mechanism of the machining docking station.

[0008] A transfer device is provided above the conveying docking station to pick up and place the compressor cylinder on the clamping mechanism of the conveying docking station.

[0009] Furthermore, the rotary machining table also includes a locking mechanism, which includes two positioning seats symmetrically arranged at the bottom of the worktable around the center of the vertical rotation axis. The positioning seats have positioning grooves on their sides near the vertical rotation axis. The locking mechanism also includes a locking block movably arranged on the base. The locking block moves radially along the vertical rotation axis and is inserted into the positioning groove to fix the worktable.

[0010] Furthermore, the clamping mechanism uses an air source as a driving force to clamp the compressor cylinder; the rotary processing table also includes a safety mechanism, which includes a first air guide block fixedly mounted on the worktable and a second air guide block vertically mounted on the base. The first air guide block has a first air guide channel communicating with the clamping mechanism, and the opening at one end of the first air guide channel is located on the bottom surface of the first air guide block; the second air guide block has a second air guide channel communicating with an air source device, and the opening at one end of the second air guide channel is located on the top surface of the second air guide block. The top surface of the second air guide block is sealed against the bottom surface of the first air guide block, thereby realizing the communication between the first air guide channel and the second air guide channel.

[0011] Furthermore, the machining center is a sixteen-axis machining center, which includes:

[0012] The milling and drilling mechanism includes a lifting frame and sixteen machining spindles that are rotatably mounted on the lifting frame. The sixteen machining spindles are arranged in a 4×4 array. A spindle motor is provided on the lifting frame, which simultaneously drives the sixteen machining spindles to rotate.

[0013] A first moving mechanism is used to drive the milling and drilling mechanism to move along a first direction;

[0014] The second moving mechanism is used to drive the milling and drilling mechanism to move along a second direction, wherein the first direction and the second direction are mutually perpendicular directions on a horizontal plane;

[0015] A lifting mechanism is used to drive the milling and drilling mechanism to move up and down in the vertical direction.

[0016] Furthermore, the machining spindle includes a primary spindle and a secondary spindle. There are four primary spindles and twelve secondary spindles. The primary spindles are equipped with primary and secondary transmission synchronous pulleys, and the secondary spindles are equipped with secondary transmission synchronous pulleys. The primary transmission synchronous pulleys on the four primary spindles form a primary transmission group through a first synchronous belt. One primary spindle and the secondary transmission synchronous pulleys on the three secondary spindles form a secondary transmission group through a second synchronous belt. One of the primary spindles is connected to the spindle motor for transmission.

[0017] Furthermore, the transfer device includes:

[0018] The first frame is movable and can be raised and lowered.

[0019] The second frame is rotatably mounted on the first frame about a horizontal axis;

[0020] A plurality of first gripping components are arranged at intervals along a horizontal straight line on the second frame;

[0021] A plurality of second gripping components are arranged at intervals along a horizontal straight line on the second frame, and the gripping direction of the second gripping components is perpendicular to the gripping direction of the first gripping components;

[0022] The rotating mechanism drives the second frame to rotate around the horizontal axis, thereby adjusting the gripping direction of the first gripping component and the second gripping component.

[0023] Furthermore, the rotating mechanism includes a drive cylinder, the cylinder body of which is hinged to the first frame, and the piston rod of which is hinged to the second frame; when the piston rod of the drive cylinder moves from one stroke limit to another stroke limit, the gripping direction of the first gripping assembly and the second gripping assembly rotates by 90°.

[0024] Furthermore, both the first gripping component and the second gripping component include pneumatic grippers to clamp the compressor cylinder. The pneumatic grippers include two movable blocks driven by air pressure that are either far apart or close together. Each movable block is provided with an L-shaped gripper. The L-shaped gripper includes a mounting plate and a clamping plate that are perpendicular to each other. The mounting plate has a strip hole, which is bolted to the movable block. The inner walls of the two clamping plates clamp the outer peripheral wall of the compressor cylinder. A limiting block is protruding on the inner wall of the clamping plate to prevent the compressor cylinder from moving away from the end face of the pneumatic grippers.

[0025] Furthermore, the first gripping assembly and the second gripping assembly also include a pushing mechanism. The pushing mechanism includes a positioning frame, which includes a positioning plate perpendicular to the gripping direction. Multiple push rods are slidably sleeved on the positioning plate. A push plate is fixedly connected to each push rod, and a spring is sleeved on each push rod. One end of the spring abuts against the positioning plate, and the other end abuts against the push plate. A blocking part is provided on the push rod to limit the maximum stroke of the push plate away from the positioning plate. Driven by the spring, the push rod pushes the compressor cylinder close to the end face of the pneumatic gripper.

[0026] Furthermore, the moving block is provided with a first rack portion near the L-shaped gripper, and the mounting plate is provided with a second rack portion near the wall of the moving block, wherein the first rack portion and the second rack portion mesh.

[0027] The beneficial effects of this invention are as follows: the rotary machining table in the modular machining unit uses a clamping mechanism to clamp and fix the compressor cylinder; the conveying docking station on the worktable is used to dock with the machining center; the machining docking station is used to dock with the transfer device; when the machining center processes the compressor cylinder at the machining docking station, it simultaneously disassembles and assembles the compressor cylinder at the conveying docking station; thus, the machining center is always in a processing state when the clamping mechanism clamps the compressor cylinder and when the conveying mechanism transports the compressor cylinder, which can effectively improve processing efficiency; multiple modular machining units can be applied on the automated production line of compressor cylinders, each modular machining unit corresponding to the processing of holes or grooves on different parts of the compressor cylinder; each modular machining unit has a compact cycle time, making the overall processing cycle time of the automated production line more compact, effectively improving the processing efficiency of compressor cylinders.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0049] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0050] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] refer to Figure 1 and Figure 9 The diagram illustrates a modular processing unit for a continuous processing production line for compressor cylinders, comprising a rotary machining table A0, a machining center, and a transfer device C0.

[0052] See again Figure 2The rotary machining table A0 is shown. The rotary machining table A0 includes a base A1, on which a worktable A2 is rotatably mounted about a vertical axis A21. A conveying docking station A22 and a processing docking station A23 are symmetrically arranged on the upper surface of the worktable A2 with the vertical axis A21 as the center. Clamping mechanisms A3 are respectively provided on the conveying docking station A22 and the processing docking station A23. Multiple clamps A31 for fixing the compressor cylinder 100 are provided on the clamping mechanisms A3. Figure 1 and Figure 9 The machining center is located above the machining docking station A23 to process the compressor cylinder 100 on the clamping mechanism A3 of the machining docking station A23; the transfer device C0 is located above the conveying docking station A22 to pick up and place the compressor cylinder 100 on the clamping mechanism A3 of the conveying docking station A22.

[0053] Specifically, the rotary machining table A0 in this modular machining unit uses the clamping mechanism A3 to clamp and fix the compressor cylinder 100. The conveying docking station A22 on the worktable A2 is used to dock with the machining center, and the machining docking station A23 is used to dock with the transfer device C0. When the machining center processes the compressor cylinder 100 on the machining docking station A23, it simultaneously disassembles and assembles the compressor cylinder 100 on the conveying docking station A22. In this way, the machining center is always in a processing state when the clamping mechanism A3 clamps the compressor cylinder 100 and when the conveying mechanism transports the compressor cylinder 100, which can effectively improve the processing efficiency. Multiple modular machining units can be applied on the automated production line of the compressor cylinder 100. Each modular machining unit is used to process holes or grooves on different parts of the compressor cylinder 100. Each modular machining unit has a compact cycle, which makes the overall processing cycle of the automated production line more compact and effectively improves the processing efficiency of the compressor cylinder 100.

[0054] refer to Figure 2-4 To facilitate the rotation of the worktable A2, a rotating mechanism A4 is provided on the base A1 for driving the rotation of the worktable A2. The rotating mechanism A4 includes a rotary motor A41 and a first transmission gear A42 driven by the rotary motor A41. A second transmission gear A211 is provided on the vertical rotating shaft A21, and the first transmission gear A42 meshes with the second transmission gear A211. In this embodiment, the rotary motor A41 drives the worktable A2 to rotate 180° around the vertical rotating shaft A21 each time, causing the positions of the two clamping mechanisms A3 to switch, transferring the clamped compressor cylinder 100 to be processed to the processing docking station A23, and transferring the processed compressor cylinder 100 to the conveying docking station A22.

[0055] refer to Figure 2 and Figure 3 Preferably, the rotary machining table A0 further includes a locking mechanism A5. The locking mechanism A5 includes two positioning seats A51 symmetrically arranged at the bottom of the worktable A2 around the vertical rotation axis A21. The positioning seats A51 have positioning grooves A511 on their sides near the vertical rotation axis. The locking mechanism A5 also includes a locking block A52 movably disposed on the base A1. The locking block A52 moves radially along the vertical rotation axis A21 and is inserted into the positioning grooves A511 to fix the worktable A2. To facilitate the stable movement of the locking block A52, the base A1 is provided with a guide rail A54 slidably connected to the locking block A52, and a locking cylinder A53 for driving the locking block A52 to move along the guide rail A54. Thus, when the locking block A52 is inserted into the positioning slot A511 of the positioning seat A51, the worktable A2 cannot rotate, thus preventing the worktable A2 from rotating before the machining center has completed the machining process.

[0056] refer to Figure 1 , Figure 2 and Figure 4 Preferably, the clamp A31 on the clamping mechanism A3 clamps the compressor cylinder 100 using an air source as the driving force. The rotary processing table A0 also includes a safety mechanism A6, which includes a first air guide block A61 fixedly mounted on the worktable A2 and a second air guide block A62 vertically mounted on the base A1. The first air guide block A61 has a first air guide channel communicating with the clamping mechanism A3, and the opening at one end of the first air guide channel is located on the bottom surface of the first air guide block A61. The second air guide block A62 has a second air guide channel A621 communicating with an air source device (not shown), and the opening at one end of the second air guide channel A621 is located on the top surface of the second air guide block A62. The top surface of the second air guide block A62 seals against the bottom surface of the first air guide block A61, thereby achieving communication between the first air guide channel and the second air guide channel A621. The second air guide block A62 is driven to rise and fall by a lifting cylinder A63. Thus, when the second air guide block A62 is not combined with the first air guide block A61, the air source device cannot guide air to the clamping mechanism A3; that is, when the rotation position of the worktable A2 is incorrect, the clamping mechanism A3 cannot clamp and fix the compressor cylinder 100, and the machining center will not work.

[0057] In this embodiment, to further improve processing efficiency, the clamping mechanism A3 is provided with four clamps A31, which are arranged equidistantly along a straight line; and the machining center is a sixteen-axis machining center B0, capable of machining four compressor cylinders 100 at one time. The clamping mechanism A3 can adopt the prior art disclosed in CN211332232U, therefore its specific structure and clamping principle will not be described in detail here.

[0058] refer to Figure 5-7 The diagram illustrates the 16-axis machining center B0, which includes a milling and drilling mechanism B1, a lifting mechanism B2, a first moving mechanism B3, and a second moving mechanism B4. The milling and drilling mechanism includes a lifting frame B11 and sixteen machining spindles B12 rotatably mounted on the lifting frame B11. The sixteen machining spindles B12 are arranged in a 4×4 array. A spindle motor B13 is mounted on the lifting frame B11, which simultaneously drives the sixteen machining spindles B12 to rotate. The lifting mechanism B2 drives the milling and drilling mechanism B1 to move vertically. The first moving mechanism B3 drives the milling and drilling mechanism B1 to move along a first direction X. The second moving mechanism B4 drives the milling and drilling mechanism B1 to move along a second direction Y. The first direction X and the second direction Y are mutually perpendicular directions on a horizontal plane.

[0059] refer to Figure 6 and Figure 7 To facilitate the simultaneous driving of sixteen machining spindles B12 by a single spindle motor B13, each machining spindle B12 includes a primary spindle B12a and a secondary spindle B12b. There are four primary spindles B12a and twelve secondary spindles B12b. Each primary spindle B12a is equipped with a primary transmission synchronous pulley B122 and a secondary transmission synchronous pulley B123, and each secondary spindle B12b is equipped with a secondary transmission synchronous pulley B123. The primary transmission synchronous pulleys B122 on the four primary spindles B12a form a primary transmission group via a first synchronous belt B14. One primary spindle B12a and the secondary transmission synchronous pulleys B123 on the three secondary spindles B12b form a secondary transmission group via a second synchronous belt B15. One primary spindle B12a is connected to the spindle motor B13. In this embodiment, four primary spindles B12a are arranged in a 2×2 array at the center of the 4×4 array of the machining spindles B12; thus, the first synchronous belt B14 and the second synchronous belt B15 can adopt the same specification, which is convenient for setting.

[0060] Thus, the milling and drilling mechanism, with its sixteen machining spindles B12 arranged in a 4×4 array, can accommodate different tools, avoiding the need for multiple tool changes. Controlled by a single spindle motor B13, compared to existing methods using multiple spindle motors B13, control is simpler, reducing the variation between processed products and lowering equipment costs. The first moving mechanism B3, the second moving mechanism B4, and the lifting mechanism B2 are used to adjust the position of the milling and drilling mechanism B1, enabling flexible machining in three-dimensional space. In this embodiment, the sixteen machining spindles B12 can be divided into four groups by rows or columns, with each group equipped with the same type of tool, allowing the milling and drilling mechanism B1 to machine four holes or slots of different specifications on the compressor cylinder 100.

[0061] refer to Figure 8 To facilitate tool changing, both the primary spindle B12a and the secondary spindle B12b include a shaft body B121. One end of the shaft body B121 has a mounting hole B1211 arranged axially. A clamping cylinder B124 is housed within the mounting hole B1211. The sidewall of the clamping cylinder B124 has multiple circumferentially formed clamping plates B1241, with clamping holes B1242 formed between the clamping plates B1241. A drill bit is installed within each clamping hole B1242. The drill bit B126 is attached to the head, and a limiting ring B125 is threadedly connected to the end of the shaft B121. The limiting ring B125 has a through hole B1251 through which the drill bit B126 passes. The limiting ring B125 is sleeved on the outside of the clamping cylinder B124. When the limiting ring B125 moves axially along the shaft B121, it presses against the clamping plate B1241, causing the multi-lobed clamping plate B1241 to move closer to its axis. In this way, the drill bit B126 is clamped by the multi-lobed clamping plate B1241 moving closer together. When the limiting ring B125 is loosened, the multi-lobed clamping plate elastically returns to its original position, thereby releasing the drill bit B126; tool changing operation is convenient.

[0062] refer to Figure 5 Specifically, to facilitate the lifting and lowering of the milling and drilling mechanism B1, the lifting mechanism B2 includes a first movable frame B21. The first movable frame B21 is provided with a vertically arranged first slide rail B22 and a first screw B23 arranged parallel to the first slide rail B22. The first screw B23 is driven to rotate by a first motor B24. The lifting frame B11 is slidably mounted on the first slide rail B22 via a first slider B111, and the lifting frame B11 is threadedly connected to the first screw B23. Thus, the first motor B24 drives the first screw B23 to rotate, and the first screw B23 drives the lifting frame B11 to rise and fall along the first slide rail B22.

[0063] refer to Figure 5Specifically, to facilitate the movement of the milling and drilling mechanism B1 along the first direction X, the first moving mechanism B3 includes a second moving frame B31. The second moving frame B31 is provided with a second slide rail B32 horizontally arranged along the first direction X and a second screw B33 parallel to the second slide rail B32. The second screw B33 is driven to rotate by a second motor B34. The first moving frame B21 is slidably mounted on the second slide rail B32 via a second slider B211, and the first moving frame B21 is threadedly connected to the second screw B33. Thus, by driving the second screw B33 to rotate via the second motor B34, the second screw B33 drives the first moving frame B21 to move along the second slide rail B32, thereby realizing the movement of the milling and drilling mechanism B1 along the first direction X.

[0064] refer to Figure 5 Specifically, to facilitate the movement of the milling and drilling mechanism B1 along the second direction Y, the second moving mechanism B4 includes a base B41. The base B41 is provided with a third slide rail B42 horizontally arranged along the second direction Y and a third screw B43 parallel to the third slide rail B42. The third screw B43 is driven to rotate by a third motor B44. The second moving frame B31 is slidably mounted on the third slide rail B42 via a third slider B311, and the second moving frame B31 is threadedly connected to the third screw B43. Thus, by driving the third screw B43 to rotate via the third motor B44, the third screw B43 drives the second moving frame B31 to move along the third slide rail B42, thereby realizing the movement of the milling and drilling mechanism B1 along the second direction Y.

[0065] refer to Figure 9-13 The diagram illustrates the transfer device C0, which includes a first frame C1, a second frame C2, a plurality of first gripping components C3a, a plurality of second gripping components C3b, and a rotating mechanism C4. The first frame C1 is movable and height-adjustable, and the second frame C2 is rotatably mounted on the first frame C1 about a horizontal axis C21. The first gripping components C3a are arranged at intervals along a horizontal straight line on the second frame C2. The second gripping components C3b are arranged at intervals along a horizontal straight line on the second frame C2, and the gripping direction of the second gripping components C3b is perpendicular to the gripping direction of the first gripping components C3a. The rotating mechanism C4 drives the second frame C2 to rotate about the horizontal axis C21, thereby adjusting the gripping directions of the first gripping components C3a and the second gripping components C3b.

[0066] In this embodiment, the transfer process of the transfer device C0 is described based on the prior art of the clamping mechanism A3, which adopts the technology disclosed in CN211332232U. In the initial state, as Figure 10 From this perspective, the gripping direction of the first gripping component C3a is horizontal to the left, while the gripping direction of the second gripping component C3b is vertically downward; the first gripping component C3a first grips the compressor cylinder 100 to be processed, and uses the rotating mechanism C4 to drive the second frame C2 to rotate, so that the gripping directions of the first gripping component C3a and the second gripping component C3b are as follows: Figure 11 As shown, at this time, the gripping direction of the second gripping component C3b is horizontal to the left. The second gripping component C3b first grips the compressor cylinder 100 of the clamping mechanism A3 on the conveying docking station A22. The rotating mechanism C4 drives the second frame C2 to rotate and reset. The first gripping component C3a places the compressor cylinder 100 to be processed onto the clamping mechanism A3 on the conveying docking station A22 for clamping and fixing. The movement of the first frame C1 allows the second gripping component C3b to send the processed compressor cylinder 100 to the next process or a set position. During the transfer process achieved by the transfer device C0, the sixteen-axis machining center B0 is still processing. It should be noted that if the compressor cylinder 100 is placed horizontally when clamped, the sixteen-axis machining center B0 processes the end face of the compressor cylinder 100. If the compressor cylinder 100 is placed vertically when clamped, the sixteen-axis machining center B0 processes the outer peripheral wall of the compressor cylinder 100.

[0067] refer to Figure 9-11 To facilitate rotation, the rotating mechanism C4 includes a drive cylinder. The cylinder body of the drive cylinder is hinged to the first frame C1, and the piston rod of the drive cylinder (not shown in the figure) is hinged to the second frame C2. When the piston rod of the drive cylinder moves from one stroke limit to another, the gripping direction of the first gripping component C3a and the second gripping component C3b rotates by 90°, ensuring precise switching of the gripping directions of the first gripping component C3a and the second gripping component C3b. Specifically, the first frame C1 includes two spaced-apart side plates C11, and the second frame C2 is disposed between the two side plates C11. An L-shaped connecting member C22 is provided on the second frame C2. The L-shaped connecting member C22 includes a first connecting plate C221 and a second connecting plate C222 that are perpendicular to each other. The first connecting plate C221 is detachably fixed to the second frame C2, and the second connecting plate C222 is hinged to the piston rod of the drive cylinder. It should be noted that the movement trajectory of the piston rod end of the drive cylinder is arc-shaped.

[0068] refer to Figure 9-13For ease of setup, the first gripping component C3a and the second gripping component C3b have the same structure. Both the first gripping component C3a and the second gripping component C3b include a pneumatic gripper C31, which clamps the compressor cylinder 100. The pneumatic gripper C31 includes two movable blocks C311 driven by air pressure and moving away from or close to each other. Each movable block C311 is equipped with an L-shaped gripper C312. The L-shaped gripper C312 includes a mounting plate C3121 and a clamping plate C3122 that are perpendicular to each other. The mounting plate C3121 has a strip-shaped hole C3124, which is bolted to the movable block C311. The inner walls of the two clamping plates C3122 clamp the outer peripheral wall of the compressor cylinder 100. A limiting block C3123 protrudes from the inner wall of the clamping plate C3122, preventing the compressor cylinder 100 from moving away from the end face of the pneumatic gripper C31. The L-shaped gripper C312 can be adjusted on the moving block C311 through the strip hole C3124 to accommodate compressor cylinders 100 of different sizes. When the clamping plate C3122 clamps the compressor cylinder 100, the limiting block C3123 can prevent the compressor cylinder 100 from moving away from the pneumatic gripper C31, ensuring stable clamping.

[0069] refer to Figure 12 and Figure 13 Preferably, the movable block C311 is provided with a first rack portion C3111 near the L-shaped gripper C312, and the mounting plate C3121 is provided with a second rack portion C3125 near the wall surface of the movable block C311. The first rack portion C3111 and the second rack portion C3125 mesh. In this way, the limiting action of the first rack portion C3111 and the second rack portion C3125 can prevent relative sliding between the movable block C311 and the mounting plate C3121, thus preventing loosening when clamping the compressor cylinder 100.

[0070] refer to Figure 12 and Figure 13Preferably, to further improve the stability of the compressor cylinder 100 when it is clamped, the first gripping assembly C3a and the second gripping assembly C3b further include a pushing mechanism C32. The pushing mechanism C32 includes a positioning frame C321, which includes a positioning plate C3211 perpendicular to the gripping direction. Multiple push rods C322 are slidably sleeved on the positioning plate C3211. A push plate C323 is fixedly connected to each push rod C322. A spring C324 is sleeved on the 22, with one end abutting against the positioning plate C3211 and the other end abutting against the push plate C323. The push rod C322 has a blocking part C3221, which limits the maximum stroke of the push plate C323 away from the positioning plate C3211. Driven by the spring C324, the push rod C322 pushes the compressor cylinder 100 closer to the end face of the pneumatic gripper C31. Thus, the push rod C322 and the limiting block C3123 can clamp the compressor cylinder 100. Furthermore, the first gripping assembly C3a and the second gripping assembly C3b also include sensors for sensing the position of the blocking part C3221. Thus, by sensing the position of the blocking part C3221, the sensor determines whether the compressor cylinder 100 is fully inserted between the two clamping plates C3122, ensuring that after the two clamping plates C3122 are closed, the limiting block C3123 on the clamping plate C3122 is located at the end of the compressor cylinder 100 away from the pneumatic gripper C31.

[0071] In some specific embodiments, multiple modular machining units can form an automated production line for compressor cylinders 100. Each modular machining unit contains a 16-axis machining center B0 with four sets of cutting tools. Different holes or grooves on the compressor cylinder 100 are machined through different modular machining units, thus achieving a one-time complete machining of the compressor cylinder 100 without the need to replace cutting tools except for maintenance. Adjacent modular machining units can be equipped with machining position adjustment devices, such as those disclosed in CN212100949U. A second gripping component C3b on a transfer device C0 delivers the compressor cylinder 100 to the rear machining position adjustment device, which adjusts the posture of the compressor cylinder 100. The first gripping component C3a on the rear transfer device C0 can then retrieve the part from the front machining position adjustment device. The modular machining units in this embodiment are consistent and interconnected, allowing for flexible configuration of automated production lines based on different models and specifications of compressor cylinders 100, resulting in high machining efficiency for the compressor cylinder 100.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
