Description

Technical Field

[0001] This application belongs to the field of mechanical automation processing technology, and more specifically, it relates to a quick material changing mechanism for a precision lathe. Background Technology

[0002] With the continuous advancement of automation technology, the design of quick material change mechanisms has become an important direction for improving the performance of precision lathes. However, during the material change process, traditional precision lathes usually require manual adjustment of the clamping device and workpiece position, which is not only time-consuming and labor-intensive but also reduces production efficiency. In addition, although there are some quick material change mechanism designs on the market, they generally suffer from problems such as complex structure, high cost, and poor adaptability.

[0003] Therefore, developing a quick material changing mechanism for precision lathes that is simple in structure, easy to operate, stable and reliable, and can rapidly improve production efficiency has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this application is to provide a quick material changing mechanism for a precision lathe, so as to solve the problems of low production efficiency, complex structure, high cost and poor adaptability in related technologies.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] A quick material change mechanism for a precision lathe is provided, comprising:

[0007] Clamping device, used to clamp the rotor to be processed and / or the rotor that has been processed;

[0008] A rotating device is fixedly connected to a clamping device to drive the clamping device to rotate;

[0009] A lifting device is located below the rotating device to drive the rotating device and the clamping device to rise and fall.

[0010] In this embodiment, to address the problem of low material changing efficiency during the production process of the precision lathe, the inventors proposed a novel rapid material changing mechanism. This mechanism, through the coordinated use of a clamping device, a rotating device, and a lifting device, significantly improves work efficiency and reduces the complexity of operator tasks.

[0011] In this embodiment, the clamping device is used to securely clamp the rotor to be processed and / or the already processed rotor; the rotating device is fixedly connected to the clamping device, driving the clamping device to quickly rotate to the position of the next process; the lifting device is located below the rotating device, responsible for adjusting the height of the clamping device so that the clamping device is not obstructed by the protruding parts of the finishing machine when turning to the position of the next process, and adjusting the clamping device to the appropriate height of the next process by lifting; during use, the number of clamping devices can be one, that is, when there is only one clamping device, the clamping device is used to clamp the rotor to be processed on the conveyor belt, and the rotating device drives the clamping device to quickly rotate to the rotor processing position. Above or below the rotor opening, the clamping device is driven to rise or fall to align with the rotor processing opening via a lifting device. After alignment, the precision lathe clamps the rotor for precision machining. After the rotor is machined, the precision lathe pushes the rotor to the clamping position of the clamping device. After the clamping device securely holds the rotor, it is driven to fall or rise via a lifting device. Then, the clamping device is rotated to the same or another rotor conveyor belt via a rotating device. The clamping device is then driven to rise or fall via a lifting device until it reaches a height where the rotor can be released. Finally, the machined rotor is released via the clamping device, allowing it to be transferred to the next processing step.

[0012] Furthermore, during use, the number of clamping devices can be several, divided into an equal number of first and second parts. All clamping devices in the first part clamp the rotor to be processed, while all clamping devices in the second part clamp the processed rotor; that is, the actions of clamping the rotor to be processed and the processed rotor are performed synchronously. At this time, a rotating device drives all clamping devices in the first part to quickly rotate above or below several rotor processing ports, simultaneously driving all clamping devices in the second part to quickly rotate above the same or another rotor conveyor belt. Then, a lifting device raises all clamping devices in the first part... The processing rotor is aligned with the rotor processing port of the precision lathe. At the same time, all the clamping devices in the second part are raised or lowered to a height that can release the rotor. Then, the rotor processing port of the precision lathe receives the processing rotor from all the clamping devices in the first part. All the clamping devices in the second part release the processed rotor to the rotor conveyor belt, so that the rotor is conveyed to the next processing step. Then, the above actions are repeated through the clamping device, rotating device and lifting device, so that the precision lathe's quick material changing mechanism cycles back and forth to grab the rotor to be processed and the processed rotor, and simultaneously convey the rotor to be processed and the processed rotor to the next process.

[0013] In this embodiment, the cooperation of the clamping device, rotating device and lifting device significantly improves work efficiency and reduces the complexity of worker operation, reduces operational errors caused by human factors, and achieves efficient, stable and reliable material changing operation, meeting the urgent needs of modern production for rapid material changing.

[0014] In one embodiment, the rotating device includes a rotating cylinder and a fixed seat. The fixed seat is fixedly connected to the bottom of the rotating cylinder, and the fixed seat extends outward in a partial manner to form two fixed beams or one fixed beam. The clamping device is disposed on the fixed beam.

[0017] In one embodiment, the two ends of a fixed beam extend in opposite directions, and the fixed beam forms a bending angle greater than or equal to 0° and less than 180°.

[0018] In one embodiment, a number of clamping devices are distributed on a fixed beam, and the clamping devices are evenly arranged on the left and right sides of the reference line with the vertical line of the fixed beam as the reference line.

[0019] The clamping directions of the clamping devices on the same side are all the same.

[0020] In one embodiment, the lifting device includes a fixed bracket, a pneumatic telescopic rod, and an air pump;

[0021] A rotating sleeve is provided at the bottom of the fixed base, and the air pump is fixedly connected to the bottom of the fixed bracket.

[0022] The pneumatic telescopic rod is fitted inside the fixed bracket, with one end of the pneumatic telescopic rod extending into the rotating sleeve and the other end connected to the air pump.

[0023] In one embodiment, a bearing is also provided between the pneumatic telescopic rod and the rotating sleeve.

[0024] In one embodiment, the clamping device includes a cylinder and a clamping component, the cylinder being fixed to a fixed beam and the cylinder driving the clamping component to move.

[0046] Please see Figures 1-8 The present application will now describe a quick material change mechanism for a precision lathe according to an embodiment. This quick material change mechanism for a precision lathe includes:

[0047] A clamping device for clamping a rotor to be processed and / or a rotor that has been processed;

[0048] A rotating device, which is fixedly connected to the clamping device, to drive the clamping device to rotate;

[0049] A lifting device is provided below the rotating device to drive the rotating device and the clamping device to rise and fall.

[0050] In this embodiment, to address the problem of low material changing efficiency during the production process of the precision lathe, the inventors proposed a novel rapid material changing mechanism. This mechanism, through the coordinated use of a clamping device, a rotating device, and a lifting device, significantly improves work efficiency and reduces the complexity of operator tasks.

[0051] In this embodiment, the clamping device can be one of a pneumatic clamping device, an electric clamping device, or a hydraulic clamping device; the rotating device can be one of a pneumatic rotating device, an electric rotating device, or a hydraulic rotating device; and the lifting device can be one of a pneumatic lifting device, an electric lifting device, or a hydraulic lifting device.

[0052] In this embodiment, the clamping device is used to securely clamp the rotor to be processed and / or the already processed rotor; the rotating device is fixedly connected to the clamping device, driving the clamping device to quickly rotate to the position of the next process; the lifting device is located below the rotating device and is responsible for adjusting the height of the clamping device so that the clamping device is not obstructed by the protruding parts of the finishing machine when turning to the position of the next process; during use, if... Figure 4 As shown, the number of clamping devices can be one. When there is only one clamping device, it is used to clamp the rotor to be processed on the conveyor belt. The clamping device is driven by the rotating device to quickly rotate to the top or bottom of the rotor processing opening. Then, the clamping device is driven by the lifting device to rise or fall to align with the rotor processing opening. After alignment, the finishing machine clamps the rotor to be processed for finishing. After the rotor is processed, the finishing machine pushes the rotor to the clamping position of the clamping device. After the clamping device firmly clamps the rotor, it is driven by the lifting device to fall or rise. Then, the clamping device is rotated by the rotating device to the top of the same or another rotor conveyor belt. Then, the clamping device is driven by the lifting device to rise or fall to the height where the rotor can be released. Then, the finished rotor is released by the clamping device, so that the finished rotor can be transferred to the next processing step.

[0053] Furthermore, during use, such as Figures 5-8As shown, the number of clamping devices can be several, divided into an equal number of first and second parts. All clamping devices in the first part clamp the rotor to be processed, while all clamping devices in the second part clamp the processed rotor. That is, the actions of clamping the rotor to be processed and the processed rotor are performed synchronously. At this time, a rotating device drives all clamping devices in the first part to quickly rotate above or below several rotor processing ports, simultaneously driving all clamping devices in the second part to quickly rotate above the same or another rotor conveyor belt. Then, a lifting device raises the rotors on all clamping devices in the first part to... The rotor is aligned with the machining port of the precision lathe. At the same time, all the clamping devices in the second part are raised or lowered to a height that can release the rotor. Then, the machining port of the precision lathe receives the rotors to be processed from all the clamping devices in the first part. All the clamping devices in the second part release the processed rotors to the rotor conveyor belt, so that the rotors are conveyed to the next processing step. Then, the above actions are repeated through the clamping devices, rotating devices and lifting devices, so that the precision lathe's quick material changing mechanism cycles back and forth to simultaneously grab the rotors to be processed and the processed rotors, and simultaneously convey the rotors to be processed and the processed rotors to the next process.

[0054] In this embodiment, the cooperation of the clamping device, rotating device and lifting device significantly improves work efficiency and reduces the complexity of worker operation, reduces operational errors caused by human factors, and achieves efficient, stable and reliable material changing operation, meeting the urgent needs of modern production for rapid material changing.

[0055] In one embodiment, see Figures 1-3 As a specific embodiment of a novel quick material changing mechanism provided in this application, the rotating device includes a rotating cylinder 3 and a fixed seat 4. The fixed seat 4 is fixedly connected to the bottom of the rotating cylinder 3, and the fixed seat 4 extends outward in a partial manner to form two fixed beams 5 or one fixed beam 5. The clamping device is disposed on the fixed beam 5.

[0056] In this embodiment, the rotary cylinder 3 is a pneumatic rotary cylinder connected to the air pipe 11. The air pipe 11 controls the rotation of the rotary cylinder 3 by inlet and outlet air. As a driving component, the rotary cylinder 3 can provide the power required for rotation, driving the fixed seat 4 to rotate. The fixed seat 4 provides a stable mounting position for the clamping device through two fixed beams 5 or one fixed beam 5 that extend outward locally. When the rotary cylinder 3 starts working, the fixed seat 4 rotates accordingly, thereby driving the clamping device set on the fixed beam 5 to rotate synchronously, so that it can quickly and accurately transfer the rotor to be processed to the rotor processing port of the precision lathe according to a predetermined program and angle, or transfer the processed rotor to the corresponding rotor conveyor belt, which facilitates the connection of subsequent processes. Moreover, this structural design makes the entire rotating device relatively simple and compact while ensuring strength and stability. It does not occupy too much space, which is conducive to reasonable layout within the limited space of the precision lathe. It can better cooperate with the lifting device and the entire quick material changing mechanism to complete efficient material changing operations, further improving the overall work efficiency and operational reliability. In this embodiment, the rotating cylinder 3 can be one of a pneumatic rotating cylinder, an electric rotating cylinder, or a hydraulic rotating cylinder.

[0057] In one embodiment, see Figures 5-7 As a specific embodiment of a novel quick material changing mechanism provided in this application, the two fixed beams 5 extend in opposite directions, and the included angle between the central axes of the two fixed beams 5 is greater than 0° and less than or equal to 180°.

[0058] In one embodiment, see Figure 1 , Figure 2 , Figures 5-7 As a specific embodiment of a novel quick material changing mechanism provided in this application, both fixed beams 5 are provided with an equal number of clamping devices, and the clamping direction of a single clamping device on the same fixed beam 5 is the same as that of other clamping devices.

[0059] When this embodiment is implemented, as follows: Figure 1 As shown, this novel quick-change mechanism can be installed upright in the material change area using a conventional installation method, or it can be installed using... Figure 2 The method shown is to invert the components within the material changing area; all embodiments in this document are described using an inverted positional structure, which will not be repeated here; in this embodiment, as... Figure 5As shown, two fixed beams 5 extend partially from the fixed base 5 of this novel quick-change mechanism, and the included angle between the central axes of the two fixed beams is 90°. A rotor conveyor belt A is distributed on each of the left and right sides of this novel quick-change mechanism. The arrows on the rotor conveyor belt A indicate the direction of movement of the conveyor belt. A rotor precision machining machine B is installed below it. During use, the fixed beam 5 on the left side of the fixed base 4 is used to clamp the rotor 12 being processed, which is conveyed by the rotor conveyor belt A on the left side. At the same time, the fixed beam 5 below is used to clamp the rotor 12 that has been processed. After the clamping devices on the two fixed beams 5 simultaneously clamp their respective target objects, the mechanism is lifted... The lowering device drives the rotary cylinder 3 and the fixed base 4 to rise, thereby raising the clamping device. Then, the rotary cylinder 3 rotates 90° counterclockwise, positioning the clamping device holding the rotor 12 to be processed above the rotor precision turning machine B. This positions the clamping device holding the processed rotor 12 above the rotor conveyor belt A on the right. At this point, the lifting device is lowered, aligning the clamping device holding the rotor 12 with the processing opening of the rotor precision turning machine B. Simultaneously, the clamping device holding the processed rotor 12 is positioned at a height just sufficient to release the rotor 12. Then, the rotor precision turning machine B receives the rotor to be processed. The rotor 12, after being processed, is released by the clamping device, allowing it to flow along the right-side rotor conveyor belt A to the next process. Next, a clamping device aligned with the machining port of the finishing machine B is used to hold the processed rotor 12 from the finishing machine B. A clamping device located above the right-side rotor conveyor belt A is used to hold the rotor 12 being processed, which is being conveyed from the right-side rotor conveyor belt A. When both devices simultaneously clamp their respective target objects, the lifting device drives the rotary cylinder 3 and the fixed base 4 to rise, thereby raising the clamping device. The rotary cylinder 3 rotates 90° clockwise, thus clamping the rotor to be processed. The clamping device of rotor 12 is located above the rotor precision turning machine B, so that the clamping device holding the finished rotor 12 is located above the rotor conveyor belt A on the left. At this time, by controlling the lifting device to descend, the clamping device holding the rotor 12 to be processed is aligned with the processing port of the rotor precision turning machine B. At the same time, the clamping device holding the finished rotor 12 is positioned at the height that can just release the rotor 12. Then, the rotor precision turning machine B receives the rotor 12 to be processed, and the clamping device holding the finished rotor 12 releases the rotor 12, so that the finished rotor 12 flows along the rotor conveyor belt A on the left to the next process.This automated material changing method, which involves alternating left and right movements in a repetitive cycle, achieves efficient and orderly flow between rotors awaiting processing and those already processed. This significantly improves material changing efficiency, reduces the frequency of manual intervention and associated operational complexity. Furthermore, this repetitive working mode ensures equipment stability during long-term operation, minimizing the risk of equipment failure due to frequent changes in operating methods or human error, thus guaranteeing production reliability.

[0060] Furthermore, such as Figure 6 As shown, in this embodiment, the novel quick-change mechanism is similar to the one described above. Figure 5 The working principle of the new quick material changing mechanism shown is the same. The only core difference is that two clamping devices are set on its two fixed beams 5. This design allows for the simultaneous processing of multiple rotors and the release and transfer of multiple processed rotors at the same time, which can further improve the material changing rate.

[0061] Furthermore, such as Figure 7 As shown, this novel rapid material changing mechanism has a 180° included angle between the central axes of its two fixed beams 5. Two clamping devices are installed above each of the two fixed beams 5, and there is only one rotor conveyor belt A. During operation, the clamping device located above rotor conveyor belt A clamps the rotor 12 to be processed conveyed by rotor conveyor belt A, while the clamping device aligned with the machining port of rotor precision turning machine B clamps the rotor 12 already processed by rotor precision turning machine B. When the clamping devices simultaneously clamp their respective target objects, the lifting device drives the rotary cylinder 3 and the fixed seat 4 to rise, thereby raising the clamping devices. Then, the rotary cylinder 3 rotates 180° clockwise or counterclockwise to clamp the rotor to be processed. The clamping device of rotor 12 is located above the rotor precision turning machine B, so that the clamping device holding the processed rotor 12 is above the right rotor conveyor belt A. At this time, by controlling the lifting device to descend, the clamping device holding the rotor 12 is aligned with the processing port of the rotor precision turning machine B, and the clamping device holding the processed rotor 12 is positioned at a height that allows the rotor 12 to be released. Then, the rotor precision turning machine B receives the rotor 12 to be processed, and the clamping device holding the processed rotor 12 releases the rotor 12, allowing the processed rotor 12 to flow along the rotor conveyor belt A to the next process. Through this cyclical automated material changing method, this embodiment and Figure 5 , Figure 6 Compared to reducing the number of rotor conveyor belts A, this method improves material changing efficiency while further controlling costs and enhancing economic viability.

[0062] In one embodiment, see Figure 8As a specific embodiment of a quick material changing mechanism for a precision lathe provided in this application, the two ends of a fixed beam 5 extend in opposite directions, and the fixed beam forms a bending angle, wherein the bending angle is greater than or equal to 0° and less than 180°.

[0063] In one embodiment, see Figure 8 As a specific embodiment of a quick material changing mechanism for a precision lathe provided in this application, a plurality of clamping devices are distributed on the fixed beam, and the plurality of clamping devices are evenly arranged on the left and right sides of the reference line with the vertical line of the fixed beam as the reference line.

[0064] The clamping directions of the clamping devices on the same side are all the same.

[0065] In the implementation of this embodiment, as follows: Figure 8 As shown, there is only one fixed beam 5 in this embodiment. The two ends of the fixed beam 5 extend in opposite directions. The fixed beam 5 is set on the fixed base 4. The single fixed beam 5 reduces the vibration interference caused by the rotation of the rotary cylinder 3 during rotation. That is, the clamping device on the fixed beam is more stable during rotation, and the rotor on the clamping device can be more stably fixed in the clamping device. In addition, compared with two fixed beams 5 extending from the fixed base 4, it is easier to manufacture a single fixed beam 5 extending from the fixed base 4, which reduces the probability of producing defective products and can further control economic costs.

[0066] In one embodiment, see Figure 2 As a specific embodiment of a quick material changing mechanism for a precision lathe provided in this application, the lifting device includes a fixed bracket 6, a pneumatic telescopic rod 7, and an air pump 8;

[0067] A rotating sleeve 9 is provided at the bottom of the fixed base, and the air pump 8 is fixedly connected to the bottom of the fixed bracket 6;

[0068] The pneumatic telescopic rod 7 is sleeved inside the fixed bracket 6, with one end of the pneumatic telescopic rod 6 extending into the rotating sleeve 9 and the other end connected to the air pump 8.

[0069] In this embodiment, the air pump 8 is equipped with an air pipe 11. The air pipe 11 controls the air pump 8 to drive the pneumatic telescopic rod 7 to rise and fall by air intake and exhaust. The pneumatic telescopic rod 7 drives the rotary cylinder 3 and the fixed seat 4 to rise and fall by air intake and exhaust, thereby driving the clamping device to rise and fall. During the rising and falling process, the pneumatic telescopic rod 7 is sleeved on the fixed bracket 6. The fixed bracket 6 plays a guiding role, so that when the pneumatic telescopic rod 7 drives the rotary cylinder 3 and the fixed seat 4 to rise and fall, the pushing and pulling stress when the pneumatic telescopic rod 7 pushes or pulls the rotary cylinder 3 and the fixed seat 4 to rise and fall is more concentrated in the center of the fixed seat 4, thereby reducing the vibration generated during the rising and falling process and making the rising and falling more stable and smooth. In this embodiment, the air pump 8 and the pneumatic telescopic rod 7 can be replaced by a stepper motor and an electric telescopic rod, or they can be replaced by a hydraulic pump and a hydraulic telescopic rod.

[0070] In one embodiment, see Figure 2 and Figure 3 As a specific embodiment of a quick material changing mechanism for a precision lathe provided in this application, a bearing 10 is also provided between the pneumatic telescopic rod 7 and the rotating sleeve 9.

[0071] In this embodiment, the bearing 10 between the pneumatic telescopic rod 7 and the rotating sleeve 9 ensures that when the rotating cylinder 3 drives the fixed seat 4 and the clamping device to rotate, it does not drive the pneumatic telescopic rod 7 to rotate. This guarantees that the pneumatic telescopic rod 7 can independently perform lifting and lowering movements without being disturbed by rotation. The main function of the pneumatic telescopic rod 7 is to drive the rotating cylinder 3 and the fixed seat 4 to lift and lower through its own extension and retraction, thereby driving the clamping device to lift and lower, and adjusting its height to meet the positional requirements of different process stages. Without the bearing 10 for isolation and assistance, when the rotating cylinder 3 drives the fixed seat 4 and other components to rotate, the rotational force may be transmitted to the pneumatic telescopic rod 7, forcing the pneumatic telescopic rod 7 to rotate as well. This would prevent the pneumatic telescopic rod 7 from accurately adjusting the height of the clamping device according to the preset lifting and lowering commands, disrupting the orderly workflow of the entire material changing mechanism and affecting the efficiency and accuracy of material changing.

[0072] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of a quick material changing mechanism for a precision lathe provided in this application, the clamping device includes a cylinder 2 and a clamping component 1. The cylinder 2 is fixed on the fixed beam 5, and the cylinder 2 drives the clamping component 1 to move.

[0073] In this embodiment, an air pipe 11 is provided on the cylinder 2. The air pipe 11 controls the clamping components 1 on the cylinder 2 to move closer or further apart through air intake and exhaust, thereby clamping or releasing the rotor 12. In this embodiment, the process of controlling the gas intake and exhaust of the cylinder 2 through the air pipe 11 can be completed in a short time, allowing the clamping components 1 to quickly move closer or further apart. This enables efficient clamping or releasing of the rotor 12. For material changeover production processes that require frequent rotor loading and unloading and have a fast operating cycle, this can effectively improve overall work efficiency and reduce production delays caused by slow clamping actions. In case of errors; in addition, by adjusting parameters such as the air pressure in the air pipe 11, the output power of the cylinder 2 can be flexibly controlled, thereby precisely adjusting the clamping force of the clamping component 1 on the rotor. This ensures that under normal working conditions, the clamping component 1 can firmly clamp the rotor 12, preventing it from loosening or shifting and affecting the normal progress of subsequent processes, while also avoiding damage to the surface of the rotor 12 due to excessive clamping force. In this embodiment, the cylinder 2 can be replaced with a hydraulic cylinder or a drive motor, which drives the clamping components 1 to move closer or further apart through hydraulic or electric means, thereby achieving the clamping or releasing of the rotor 12 by the clamping component 1.

[0074] In one embodiment, as a specific implementation of a quick material change mechanism for a precision lathe provided in this application, the clamping component 1 includes a clamping block, a clamping plate, a jaw, or a clamping clamp.

[0075] In this example, different types of clamping components 1 each have their unique advantages, adapting to diverse material changeover production needs. Clamping blocks are generally suitable for clamping rotors 12 with relatively flat surfaces and regular dimensions; their large contact area provides stable clamping force. Clamping plates are more suited for fixing long, strip-shaped or sheet-like rotors 12; their elongated shape allows for precise contact with the sides of the rotor 12, ensuring that the rotor 12 does not rotate during clamping. The grippers are highly flexible; by adjusting the opening angle and spacing of the grippers, they can accurately grasp both small, precision rotors 12 and irregularly shaped rotors 12 with complex contours, easily handling workpieces of different shapes. Clamping clamps are mostly used for rotors 12 made of harder materials with extremely high clamping precision requirements. Their powerful clamping structure can firmly lock the rotor 12, while the precise adjustment function prevents any damage to the rotor 12 during clamping, comprehensively meeting the rapid material changeover needs of precision lathes in various rotor processing scenarios.

[0076] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0077] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
