[0051] 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.

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

[0055] refer to Figure 2 The present invention illustrates an automated processing equipment for compressor cylinder blocks, including a processing device 1, a feeding conveyor roller 2, a discharging conveyor roller 3, a single-axis clamping device 4, and a material channel switching device 5.

[0056] refer to Figures 11-15 The machining device 1 includes a machine tool spindle 11, on which a coaxially arranged internal expansion clamp 12 is connected; a turning mechanism 13 is provided on one side of the machine tool spindle 11, the turning mechanism 13 includes a movable tool holder 131, on which a first tool 1311 and a second tool 1312 are arranged separately; wherein, as Figure 15 As shown, when the workpiece (i.e., the compressor cylinder 100) is clamped onto the internal expansion fixture 12, the internal expansion fixture 12 presses against the inner wall of the workpiece to achieve clamping and fixing of the workpiece. The machine tool spindle 11 drives the workpiece to rotate. The first cutting tool 1311 and the second cutting tool 1312 are respectively located at both ends of the workpiece. After the first cutting tool 1311 finishes machining one end, the second cutting tool 1312 processes the other end. Throughout the entire machining process, there is no need to clamp the workpiece a second time or adjust the position of the workpiece. The internal expansion fixture 12 can refer to the prior art. The positions of the first cutting tool 1311 and the second cutting tool 1312 on the tool holder 131 are adjustable to accommodate workpieces of different sizes.

[0057] refer to Figure 2 and Figure 5The feeding conveyor 2 is located on one side of the processing device 1. The feeding conveyor 2 is used to arrange and convey workpieces. The feeding conveyor 2 has a feeding setting position 21, and the workpiece located at the feeding setting position 21 is axially aligned with the internal expansion clamp 12. The discharging conveyor 3 is located below the feeding conveyor 2. The discharging conveyor 3 is used to receive the workpieces processed by the processing device 1 and to arrange and convey the workpieces. The feeding conveyor 2 and the discharging conveyor 3 can realize batch feeding and discharging of workpieces. Their positional relationship is conducive to improving the utilization of space.

[0058] refer to Figure 6 and Figure 7 The single-axis clamping device 4 includes a robotic arm 41 that can move along the axial direction of the internal expansion clamp 12;

[0059] refer to Figures 6-9 The material channel switching device 5 includes a main frame 51. The main frame 51 is provided with a first bearing mechanism 52 and a second bearing mechanism 53 located obliquely below the first bearing mechanism 52. The first bearing mechanism 52 is provided with a first V-shaped support portion 521 located between the internal expansion clamp 12 and the feeding setting position 21. The second bearing mechanism 53 is provided with a second V-shaped support portion 531. The first bearing mechanism 52 includes a fixed frame 522, a tilting frame 523 hinged to the fixed frame 522, and a first driver 524 for driving the tilting frame 523 to rotate. The frame 522 is provided with a first inclined support surface 5221, and the tilting frame 523 is provided with a second inclined support surface 5231. The first V-shaped support part 521 is formed between the first inclined support surface 5221 and the second inclined support surface 5231. The tilting frame 523 is rotated by the first driver 524 so that the workpiece on the first V-shaped support part 521 slides down to the second V-shaped support part 531 under its own weight. The main frame 51 is also provided with a discharge pushing mechanism 54 for pushing the workpiece from the second V-shaped support part 531 to the discharge conveying roller 3.

[0060] Specifically, the workpiece is fed onto the feeding conveyor 2 and eventually stops at the feeding set position 21. The feeding set position 21 can be equipped with a trough structure or a baffle structure to ensure that the workpiece stops stably at the feeding set position 21. Then, the robot arm 41 moves to the feeding set position 21 to clamp the workpiece and transfers it to the inner expansion clamp 12 for clamping. After clamping, the robot arm 41 leaves the inner expansion clamp 12, and the processing device 1 processes the workpiece. After processing, the robot arm 41 retrieves the workpiece from the inner expansion clamp 12 and moves the workpiece to the first V-shaped support part 52. Above 1, the processed workpiece is placed on the first V-shaped support 521. The robot arm 41 then picks up the workpiece from the feeding setting position 21. During this process, the first driver 524 on the material channel switching device 5 drives the flipping bracket to rotate, and the angle of the second inclined support surface 5231 is changed. The workpiece located on the first V-shaped support 521 will slide down along the second inclined support surface 5231 and onto the second V-shaped support 531. The discharge pushing mechanism 54 pushes the workpiece located on the second V-shaped support 531 onto the discharge conveying roller 3. In this way, the workpiece picking action and the workpiece discharge action are performed simultaneously.

[0061] It is worth mentioning that during the above process, the robot arm 41 only moves in a straight line, that is, single-axis movement; the first V-shaped support 521 on the material channel switching device 5 is located below the movement path of the robot arm 41, so the robot arm 41 will not interfere with the first bearing mechanism 52 when it moves the workpiece; in addition, the material channel switching device makes full use of the workpiece's own weight to carry out sliding transfer, which makes the structure simple, the operation stable, and the pick-up and drop safe.

[0062] In this embodiment, a single-axis clamping device 4 is used to transfer the workpiece from the feed conveyor 2 to the internal expansion clamp 12. The robot arm 41 moves only along a single axis, resulting in a simple system control and servo drive structure, effectively reducing equipment investment costs, ensuring high system stability, and facilitating maintenance. A material channel switching device 5 is used to transfer the workpiece to the discharge conveyor 3, allowing the workpiece to be switched from the movement path of the robot arm 41 to other positions to enter the discharge conveyor 3. The structure of the material channel switching device 5 does not involve multi-axis spatial positioning, making it simple and highly stable. Compared to the method of setting up two sets of multi-axis robots, the material channel switching device 5 and the single-axis clamping device 4 cooperate with each other without interfering with each other, saving space for setting up a multi-axis servo drive structure and reducing the size of the equipment.

[0063] In some embodiments, reference Figure 9The first actuator 524 is a cylinder, which includes a cylinder body and a piston rod. The cylinder body of the first actuator 524 is hinged to the fixed frame 522, and the piston rod of the first actuator 524 is hinged to the tilting frame 523. Thus, by controlling the scaling of the piston rod on the first actuator 524, the tilt angle of the second tilting support surface 5231 can be adjusted.

[0064] In some embodiments, reference Figure 6 and Figure 8 The second supporting mechanism 53 includes a supporting bracket 532, and a second V-shaped support portion 531 is formed on the supporting bracket 532. The second supporting mechanism 53 also includes a second driver 533 for driving the supporting bracket 532 to move up and down on the main frame 51. In this embodiment, the supporting bracket 532 can move up and down, allowing the second V-shaped support portion 531 to approach the first V-shaped support portion 521. When the tilting frame 523 rotates and the workpiece slides down, the supporting bracket 532 rises, preventing a large height difference between the workpiece and the second V-shaped support portion 531 from causing a violent collision. When the workpiece is transferred to the second V-shaped support portion 531, the supporting bracket 532 descends, causing the height of the second V-shaped support portion 531 to re-align with the discharge conveyor roller 3. The second driver 533 can be a linear actuator such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0065] In some embodiments, given that there may be a certain distance between the second V-shaped support 531 and the discharge conveying roller 3, reference Figure 6 and Figure 8 The material channel switching device 5 further includes a transition guide mechanism 55, which is disposed between the second V-shaped support 531 and the discharge conveying roller 3. The transition guide mechanism 55 includes two rows of roller sets 551. In this way, the transition guide mechanism 55 enables the workpiece to move smoothly onto the discharge conveying roller 3.

[0066] For details of the above plan, please refer to [reference needed]. Figure 8 The discharge pushing mechanism 54 includes a push block 541 slidably disposed on the main frame 51. The push block 541 is driven to move by a third driver 542, which can be a linear driver such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0067] In some embodiments, to stably achieve linear movement of the robotic arm 41, reference is made to... Figure 6 and Figure 7The single-axis clamping device 4 further includes a frame 42, a movable stage 43 slidably mounted on the frame 42, and a fourth driver 44 for driving the movable stage 43 to move; the robotic arm 41 is mounted on the movable stage 43, and the robotic arm 41 is a pneumatic gripper, which includes two clamping plates 411 that can move closer or further apart from each other. The inner side of the clamping plates 411 is provided with a rubber contact block 412, and the side of the rubber contact block 412 is provided with a V-shaped groove 4121.

[0068] The V-shaped groove 4121 on the rubber contact block 412 enables the workpiece to be stably clamped and prevents it from falling. The fourth driver 44 can be a servo motor, and a rack can be set on the frame 42. The servo motor is connected to a gear, which meshes with the rack. The servo motor drives the gear to rotate, thereby moving the moving stage 43 on the frame 42.

[0069] In some embodiments, to facilitate the positioning of the workpiece when clamped on the internal expansion clamp 12, refer to Figure 12 The processing device 1 further includes a limiting mechanism 15 disposed on one side of the machine tool spindle 11. The limiting mechanism 15 includes a limiting plate 151 located at one end of the internal expansion clamp 12 and a fifth driver 152 for driving the limiting plate 151 to move axially along the internal expansion clamp 12. Thus, the limiting plate 151 can be used to block the workpiece, preventing excessive movement. When the workpiece is blocked by the limiting plate 151, the robot arm 41 stops moving, and the internal expansion clamp 12 operates.

[0070] In some embodiments, reference Figure 11 and Figure 13The processing device 1 further includes a base 14, on which the machine tool spindle 11 is rotatably mounted. A first linear drive module 132 is mounted on the base 14, and a second linear drive module 133 is mounted on the first linear drive module 132. A tool holder 131 is mounted on the second linear drive module 133. The second linear drive module 133 is driven by the first linear drive module 132 to move axially along the internal expansion clamp 12, and the tool holder 131 is driven by the second linear drive module 133 to move in a direction perpendicular to the axial direction of the internal expansion clamp 12. The moving direction is set at an angle to the horizontal plane; both the first linear drive module 132 and the second linear drive module 133 are provided with chip baffles (not marked in the figure), and the base 14 is provided with a chip collection groove 141; in this way, the metal chips generated during the processing will not enter the interior of the first linear drive module 132 and the second linear drive module 133, and because the first linear drive module 132 and the second linear drive module 133 are inclined, the metal chips are more likely to slide into the chip collection groove 141; wherein, the first linear drive module 132 and the second linear drive module 133 can be a lead screw drive mechanism.

[0071] Preferred, Reference Figure 2 and Figure 10 The processing device 1 is further equipped with a chip removal mechanism 6, which includes a chip removal rod 61 and a sixth actuator 62 for driving the chip removal rod 61 to move. The chip removal rod 61 can be made of a soft material and is used to clean metal debris from the first tool 1311 and / or the second tool 1312. Specifically, the sixth actuator 62 drives the chip removal rod 61 to a set position, and the first linear drive module 132 and the second linear drive module 133 drive the first tool 1311 and / or the second tool 1312 to move around the position of the chip removal rod 61 along a set path, so that the chip removal rod 61 can sweep off the metal debris from the first tool 1311 and / or the second tool 1312. After chip removal is completed, the sixth actuator 62 drives the chip removal rod 61 away from the processing area to avoid affecting the tool path of the first tool 1311 and / or the second tool 1312 during processing. The sixth actuator 62 can be a cylinder.

[0072] In some embodiments, to further reduce equipment costs, refer to Figure 2 and Figure 5 The feeding conveyor roller 2 is a gravity-type sliding roller, and it is inclined at an angle of 5-10° to the horizontal plane; thus, the workpiece can be fed under its own weight. Furthermore, to achieve orderly feeding of the workpiece, refer to... Figure 3The feeding conveyor roller 2 is provided with a workpiece limiting mechanism 2215. The workpiece limiting mechanism 2215 includes a liftable V-shaped pressure plate 221 and a seventh driver 222 for driving the V-shaped pressure plate 221 to rise and fall. The seventh driver 222 can be a cylinder. In this way, by using the V-shaped pressure plate 221 to press the workpiece on the feeding conveyor roller 2, a single workpiece can be placed at the feeding setting position 21, which is convenient for the robot arm 41 to pick up the material.

[0073] In some embodiments, reference Figure 4 and Figure 5 To further improve processing efficiency, the processing device 1 is provided with multiple devices. The feeding conveyor roller 2, the single-axis clamping device 4, and the material channel switching device 5 are all corresponding to the processing device 1. Multiple processing devices 1 share one discharge conveyor roller 3.

[0074] like Figure 5 As shown, multiple feeding conveyor rollers 2 are arranged side by side, and multiple processing devices 1 are all located on one side of the feeding conveyor rollers 2. The feeding setting position 21 is located at the end of the feeding conveyor roller 2 closest to the processing device 1. The remaining feeding conveyor rollers 2 are provided with material transfer slides 23 at their ends. The feeding setting position 21 is located at the end of the material transfer slides 23. The material transfer slides 23 are provided with feeding pushing mechanisms 24 for pushing the workpiece to the feeding setting position 21. All feeding setting positions 21 are equidistant from the processing device 1.

[0075] The processing device 1, the single-axis clamping device 4, and the material channel switching device 5 can be integrated into a processing unit. When all the feeding settings 21 are set to be the same distance from the processing device 1, the single-axis clamping device 4 and the material channel switching device 5 on each processing device 1 can use the same parameters, which is convenient for setting. It is also convenient to flexibly increase the number of processing units according to processing needs.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
