Description

Technical Field

[0001] The present invention relates to the field of technical equipment for gas cylinder production, and particularly to a necking spinning machine. Background Art

[0002] As an important gas storage container, gas cylinders are widely used in multiple fields such as industry, mining, military, medicine, diving, automobiles, and aerospace. In recent years, with the continuous increase in market demand, especially the growing demand for large-diameter and long-size gas cylinders, higher requirements have been put forward for the production process of gas cylinders.

[0003] In traditional gas cylinder production processes, the existence of welds often leads to problems such as discontinuity, reduced strength, brittle fracture, and tensile stress concentration, which seriously affect the service performance and safety of gas cylinders. To solve these problems, the hot spinning necking process emerged. Through hot spinning necking, a series of drawbacks related to welds can be fundamentally eliminated, and the overall performance and quality of gas cylinders can be improved.

[0004] However, during the spinning process of large-diameter and long-size gas cylinders, the clamping difficulty becomes an urgent problem to be solved. Due to the large size and heavy weight of the workpiece, traditional spinning machines often have difficulty ensuring stability and accuracy during clamping and processing, resulting in low production efficiency and difficult-to-guarantee product quality.

[0005] Therefore, in view of the spinning processing requirements for large-diameter and long-size gas cylinders, a new type of necking spinning machine is urgently needed to solve the existing problems. This new type of spinning machine needs to have higher clamping stability, processing accuracy, and production efficiency to meet the processing requirements of workpieces with different materials and weights, and promote the development of domestic hydrogen gas cylinder technology.

The spindle fixture and the auxiliary mechanism are both arranged on the main body fuselage. The main body fuselage includes a main bed, a lower sliding table, an upper sliding table, a tool wheel seat, and a double-headed tool wheel. The lower sliding table is slidably arranged left and right on the main bed, the upper sliding table is slidably arranged left and right on the lower sliding table, the tool wheel seat is slidably arranged front and back on the upper sliding table, and the double-headed tool wheel is slidably arranged up and down on the side of the tool wheel seat; The spindle fixture includes a spindle box base, a spindle box, a hollow spindle, and a double-head fixture. The spindle box base is arranged on the main body of the machine. The spindle box is installed on the upper surface of the spindle box base. The hollow spindle is installed in the inner hole of the spindle box. One end of the hollow spindle is connected with a motor, and the motor drives the hollow spindle to rotate. The double-head fixture is arranged on the hollow spindle. During processing, the double-head fixture clamps the workpiece, and the motor drives the hollow spindle, the double-head fixture, and the workpiece to rotate as a whole. The auxiliary mechanism is used to send the workpiece to be processed into the spindle fixture for clamping, and the double-head cutter wheel processes the workpiece.

[0007] Optionally, the auxiliary mechanism includes a left material support bracket and a right material support bracket distributed on both sides of the spindle fixture. The left material support bracket and the right material support bracket are respectively installed on the corresponding left material support bracket base and right material support bracket base.

Guide rails are installed on both the left material support bracket base and the right material support bracket base, enabling the left material support bracket and the right material support bracket to move in the left-right direction. Oil cylinders are installed on both the left material support bracket and the right material support bracket, which can move in the left-right direction.

[0008] Optionally, a fine adjustment mechanism is provided on the cutter wheel seat. The fine adjustment mechanism includes a screw, a guiding slide rail, and a position sensor. By rotating the screw, the cutter wheel seat is driven to displace on the guiding slide rail. The position sensor monitors and feeds back the position information of the cutter wheel seat in real time to realize the position adjustment of the double-head cutter wheel in the front-back direction and adapt to the processing requirements of workpieces with different lengths.

[0009] Optionally, a locking mechanism is provided on the upper slide table. The locking mechanism includes a pneumatic chuck, a locking pin, and a pneumatic control system. The pneumatic control system drives the pneumatic chuck to act, so that the locking pin quickly inserts into the locking hole between the upper slide table and the cutter wheel seat, realizing the quick locking and fixing of the cutter wheel seat and improving the stability and production change efficiency during the processing.

[0010] Optionally, the spindle fixture further includes an electric fixture adjustment device. The electric fixture adjustment device includes a servo motor, a transmission lead screw, and a fixture adjustment seat. The servo motor drives the fixture adjustment seat to move axially on the spindle box through the transmission lead screw, thereby adjusting the position of the double-head fixture on the hollow spindle to adapt to the automatic clamping requirements of workpieces with different diameters and improving the production flexibility and efficiency.

[0011] Optionally, an intelligent workpiece positioning device is provided on the feeding trolley. The intelligent workpiece positioning device includes a photoelectric sensor, a mechanical positioning pin, and a positioning control system. The photoelectric sensor detects the position of the workpiece and sends a signal to the positioning control system, which controls the extension and retraction of the mechanical positioning pin to achieve automatic identification and precise positioning of the workpiece, ensuring the machining accuracy and the stability of the automated production process.

[0012] Optionally, adjustable buffer devices are provided on both the left and right workpiece supporting brackets. The adjustable buffer device includes a buffer cylinder, a buffer pad, and a pneumatic pressure regulating valve.

[0013] In summary, the present invention has the following beneficial effects: By introducing a locking mechanism and a fine-tuning mechanism on the upper sliding table in this application, the processing flexibility, stability, and efficiency of the necking spinning machine are significantly improved. The locking mechanism uses a pneumatic control system to drive the pneumatic chuck and the locking pin to achieve rapid locking and release of the tool wheel seat, making the production changeover process simpler and faster without cumbersome manual adjustment, thus greatly shortening the production changeover time and improving production efficiency. At the same time, the fine-tuning mechanism allows for precise displacement adjustment of the tool wheel seat by rotating the screw to adapt to the processing requirements of workpieces with different lengths, enhancing the processing flexibility of the spinning machine.

[0014] In terms of processing stability, the locking mechanism ensures that the tool wheel seat remains stable during the processing, effectively preventing processing errors caused by vibration or deviation. In addition, the real-time monitoring and feedback mechanism of the position sensor further guarantees the accuracy and stability of the tool wheel seat position, thereby improving the processing accuracy. This improvement in stability is particularly important for the processing of workpieces with high precision requirements, helping to reduce the scrap rate and rework rate and further reducing production costs.

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Embodiment: As Figures 1-4 shown, the present invention provides a necking spinning machine, including a main body fuselage, a spindle fixture, and an auxiliary mechanism. The spindle fixture and the auxiliary mechanism are both arranged on the main body fuselage. The main body fuselage includes a main bed body 14, a lower sliding table 13, an upper sliding table 12, a cutter wheel seat 11, and a double - head cutter wheel 10. The lower sliding table 13 is slidably arranged left - and - right on the main bed body 14, the upper sliding table 12 is slidably arranged left - and - right on the lower sliding table 13, the cutter wheel seat 11 is slidably arranged front - and - back on the upper sliding table 12, and the double - head cutter wheel is slidably arranged up - and - down on the side of the cutter wheel seat 11; The spindle fixture includes a spindle box base 4, a spindle box 3, a hollow spindle 9, and a double - head fixture 8. The spindle box base 4 is arranged on the main body fuselage, the spindle box is installed on the upper surface of the spindle box base 4, the hollow spindle 9 is installed in the inner hole of the spindle box, one end of the hollow spindle 9 is connected to a motor, the motor drives the hollow spindle 9 to rotate, the double - head fixture 8 is arranged on the hollow spindle 9, and during processing, the double - head fixture 8 clamps the workpiece 7, and the motor drives the hollow spindle 9, the double - head fixture 8, and the workpiece 7 to rotate as a whole; The auxiliary mechanism is used to send the workpiece 7 to be processed into the spindle fixture for clamping, and the double - head cutter wheel processes the workpiece 7.

[0022] According to the above settings, the present application integrates the spindle fixture and the auxiliary mechanism on the main body fuselage, realizing efficient and precise spinning processing.

[0023] The spindle fixture and the auxiliary mechanism are integrated on the main body fuselage, forming a compact and efficient processing unit. This setting reduces the connection and transmission links between components, improving the rigidity and stability of the whole machine.

[0024] The main body adopts a sliding setting, including a lower slide 13, an upper slide 12 and a cutter wheel seat 11, etc., which can slide flexibly in different directions. This setting enables each component to flexibly adjust its position according to actual processing requirements, thereby adapting to the processing of workpieces 7 of different sizes and shapes.

[0025] The spindle clamp drives the hollow spindle 9 to rotate through a motor, providing stable rotational power for processing. The double-head clamp 8 allows the workpiece 7 to be firmly clamped during processing, ensuring the stability and accuracy of the processing. This clamping method also helps to reduce vibration and noise and improve processing quality.

[0026] The auxiliary mechanism is responsible for accurately delivering the workpiece 7 to be processed into the spindle fixture to prepare for subsequent processing steps. It achieves fast and accurate positioning of the workpiece 7 through precise control and motion mechanism, thereby improving processing efficiency and accuracy.

[0027] In summary, the present application realizes efficient and precise spinning processing through integrated settings, sliding adjustable body parts, stable clamping and precise auxiliary feeding mechanism, meeting the needs of different processing scenarios.

[0028] The auxiliary mechanism includes a left support bracket 1 and a right support bracket 15 distributed on both sides of the spindle fixture, and the left support bracket 1 and the right support bracket 15 are respectively installed on the corresponding left support bracket base 2 and the right support bracket base 6; The feeding trolley 5 mounted on the right supporting bracket base 6 can be driven by the oil cylinder to do lifting movement; The left support bracket base 2 and the right support bracket base 6 are both equipped with guide rails, so that the left support bracket 1 and the right support bracket 15 can move in the left and right directions; The left support bracket 1 and the right support bracket 15 are both equipped with oil cylinders, which can move in the left and right directions.

[0029] According to the above arrangement, the auxiliary mechanism further improves the automation level and processing efficiency of the whole machine.

[0030] The auxiliary mechanism realizes fully automated operation of loading, positioning and supporting the workpiece 7 by integrating advanced control systems and transmission mechanisms, which greatly reduces manual intervention, reduces labor intensity and improves production efficiency.

[0031] The left support bracket 1 and the right support bracket 15 can move left and right under the drive of the cylinder, which enables them to be flexibly adjusted according to the actual size and shape of the workpiece 7. In conjunction with the lifting and lowering movement of the feeding trolley 5, the auxiliary mechanism can achieve precise positioning of the workpiece 7 and ensure the position accuracy of the workpiece 7 during the processing.

[0032] The left workpiece supporting bracket 1 and the right workpiece supporting bracket 15 are not only responsible for positioning but also provide stable support for the workpiece 7. During the machining process, they can effectively resist external interference and vibration, ensuring the stability and machining accuracy of the workpiece 7.

[0033] The setting of the auxiliary mechanism simplifies the loading process of the workpiece 7. Through automated feeding and positioning operations, the workpiece 7 can be quickly and accurately sent into the spindle fixture, preparing for subsequent machining steps.

[0034] The auxiliary mechanism ensures the stability and accuracy of the workpiece 7 during the machining process. Its precise positioning and stable support settings reduce errors and vibration during machining, improving machining quality and product consistency.

[0035] In summary, the auxiliary mechanism provides strong support for the efficient and precise machining of the whole machine by enhancing automation, achieving precise positioning, providing stable support, simplifying the loading process, and ensuring stability and accuracy during the machining process.

[0036] A fine-tuning mechanism is provided on the tool wheel seat 11. The fine-tuning mechanism includes a screw, a guiding slide rail, and a position sensor. By rotating the screw, the tool wheel seat 11 is driven to displace on the guiding slide rail. The position sensor monitors and feeds back the position information of the tool wheel seat 11 in real time to achieve the position adjustment of the double-head tool wheel in the front-back direction, adapting to the machining requirements of workpieces 7 with different lengths.

[0037] The fine-tuning mechanism allows for precise displacement adjustment of the tool wheel seat 11 on the guiding slide rail. This means that the necking spinning machine can adapt to the machining requirements of workpieces 7 with different lengths. Without replacing or adjusting a large number of components, it can quickly adapt to the new dimensions of the workpiece 7 through the fine-tuning mechanism, greatly improving the flexibility and adaptability of machining.

[0038] By rotating the screw, the tool wheel seat 11 can make small and precise displacements on the guiding slide rail. This adjustment method is both simple and reliable, enabling very fine position adjustment to meet the requirements of high-precision machining.

[0039] The fine-tuning mechanism is equipped with a position sensor that can monitor the position of the tool wheel seat 11 in real time. The sensor feeds back the position information to the control system to ensure the accuracy and stability of the position of the tool wheel seat 11. The real-time monitoring and feedback mechanism helps to detect and correct any position deviation in a timely manner, thereby further improving machining accuracy and efficiency.

[0040] Since the fine-tuning mechanism can achieve precise displacement adjustment and position monitoring, it helps to improve the machining accuracy of the necking spinning machine. At the same time, since there is no need to frequently replace or adjust components to adapt to workpieces 7 with different lengths, the fine-tuning mechanism also improves machining efficiency.

[0041] A locking mechanism is provided on the upper sliding table 12. The locking mechanism includes a pneumatic chuck, a locking pin, and a pneumatic control system. The pneumatic control system drives the pneumatic chuck to act, so that the locking pin quickly inserts into the locking hole between the upper sliding table 12 and the cutter wheel seat 11, realizing the quick locking and fixing of the cutter wheel seat 11, and improving the stability and production change efficiency during the processing.

[0042] The locking mechanism drives the action of the pneumatic chuck through the pneumatic control system. The pneumatic control system uses compressed air as the power source and has the advantages of fast response speed and precise control.

[0043] When it is necessary to lock the cutter wheel seat 11, the pneumatic control system drives the pneumatic chuck to act. The setting of the pneumatic chuck enables it to precisely control the movement of the locking pin. Driven by the pneumatic chuck, the locking pin quickly inserts into the locking hole between the upper sliding table 12 and the cutter wheel seat 11. The setting of the locking hole ensures that the locking pin can firmly fix the cutter wheel seat 11 and prevent it from moving or vibrating during the processing.

[0044] By quickly and firmly fixing the cutter wheel seat 11, the locking mechanism significantly improves the stability of the necking spinning machine during the processing. This helps to reduce the processing error and improve the product quality. In the traditional spinning machine setting, when replacing workpieces 7 of different lengths, it often requires cumbersome adjustment and calibration work. However, the locking mechanism on the upper sliding table 12 makes the production change process simpler and faster. Just drive the pneumatic chuck through the pneumatic control system to release the locking pin, and then the cutter wheel seat 11 can be easily removed and a new workpiece 7 can be replaced, which greatly shortens the production change time and improves the production efficiency.

[0045] Since the locking mechanism improves the processing stability and simplifies the production change process, the overall production efficiency has been significantly improved. Enterprises can complete more production tasks in a shorter time, thus meeting the market demand and reducing the production cost.

[0046] The spindle fixture further includes an electric fixture adjustment device. The electric fixture adjustment device includes a servo motor, a transmission lead screw, and a fixture adjustment seat. The servo motor drives the fixture adjustment seat to move axially on the spindle box through the transmission lead screw, so as to adjust the position of the double-head fixture 8 on the hollow spindle 9 and adapt to the automatic clamping requirements of workpieces 7 with different diameters, improving the production flexibility and efficiency.

[0047] The feeding trolley 5 is provided with an intelligent workpiece 7 positioning device. The intelligent workpiece 7 positioning device includes a photoelectric sensor, a mechanical positioning pin and a positioning control system. The photoelectric sensor detects the position of the workpiece 7 and sends a signal to the positioning control system. The positioning control system controls the extension and retraction of the mechanical positioning pin to realize the automatic identification and precise positioning of the workpiece 7, ensuring the machining accuracy and the stability of the automated production process.

[0048] Adjustable buffer devices are provided on both the left workpiece supporting bracket 1 and the right workpiece supporting bracket 15. The adjustable buffer device includes a buffer cylinder, a buffer pad and a pneumatic pressure regulating valve. The buffer cylinder controls the extension length and buffer force of the buffer pad through the pneumatic pressure regulating valve to realize the impact absorption and buffer effect adjustment during the workpiece 7 handover process, protect the surface of the workpiece 7 and the equipment structure, and at the same time adapt to the processing requirements of workpieces 7 with different materials and weights.

[0049] This work process details the working process of a necking spinning machine, from the loading of the workpiece 7 to the completion of processing and then to the unloading of the workpiece, which is a complete cycle. It mainly involves the coordinated work of key components such as a truss manipulator, a feeding trolley 5, a workpiece supporting bracket, a spindle fixture, a gas gun and a double-headed cutter wheel.

[0050] This application includes the following specific working steps during use: Loading stage The truss manipulator, through a preset program control, accurately picks up the workpiece 7 to be processed from the storage area and smoothly places it at the designated position on the feeding trolley 5.

[0051] After receiving the signal indicating the completion of loading, the feeding trolley 5 starts the lifting mechanism, smoothly raises the workpiece 7, and precisely aligns the center of the workpiece 7 with the center of the hollow spindle 9 through a precise positioning system.

[0052] Workpiece 7 pushing and clamping stage After receiving the pushing instruction, the right workpiece supporting bracket starts the pushing mechanism, holds the right side of the workpiece 7, cooperates with the feeding trolley 5, and jointly and smoothly pushes the workpiece 7 into the clamping range of the double-headed fixture 8 and the hollow spindle 9.

[0053] After receiving the clamping instruction, the double-headed fixture 8 starts the clamping mechanism to firmly clamp the workpiece 7 on the hollow spindle 9 to ensure the stability during the processing.

[0054] After completing the pushing task, the feeding trolley 5 and the right workpiece supporting bracket respectively start the retracting mechanism and smoothly retract to their original positions, waiting for the next work cycle.

[0055] Processing preparation stage After receiving the rotation instruction, the hollow spindle 9 starts the rotation mechanism and begins to rotate at a preset speed to prepare for the subsequent machining process.

[0056] After receiving the ignition instruction, the blowtorch starts the ignition mechanism to heat the workpiece 7 to the temperature required for machining.

[0057] Machining stage After receiving the machining instruction, the double-headed cutter wheel starts the moving mechanism, moves along the preset trajectory to the machining position, and performs precise spinning machining on one end of the workpiece 7.

[0058] After one end is machined, the double-headed cutter wheel starts the moving mechanism again, moves to the other end of the workpiece 7, and performs the same machining process.

[0059] After both ends are machined, the hollow spindle 9 stops rotating, and the double-headed cutter wheel starts the retracting mechanism, retracts along the original path to the original position, and waits for the next machining cycle.

[0060] Workpiece 7 loosening and blanking preparation stage After receiving the moving instruction, the left and right workpiece supporting brackets start the pushing mechanisms respectively, move towards the workpiece 7, and extend the ejector disks to clamp both sides of the workpiece 7.

[0061] After receiving the loosening instruction, the double-headed fixture 8 starts the loosening mechanism to loosen the workpiece 7 and prepare for the blanking operation.

[0062] Blanking stage After clamping the workpiece 7, the left and right workpiece supporting brackets start the rightward moving mechanisms to smoothly carry the workpiece 7 out of the machining area.

[0063] After receiving the moving instruction, the feeding trolley 5 starts the moving mechanism, moves under the workpiece 7, and starts the lifting mechanism to catch the workpiece 7.

[0064] After completing the task of carrying out, the left and right workpiece supporting brackets start the loosening mechanisms and retracting mechanisms respectively to loosen the workpiece 7 and retract to the original positions.

[0065] After catching the workpiece 7, the feeding trolley 5 starts the moving mechanism to send the workpiece 7 to a preset appropriate position and waits for the subsequent picking operation.

[0066] Workpiece 7 picking stage After receiving the picking instruction, the truss manipulator starts the moving mechanism, moves above the feeding trolley 5, and starts the lowering mechanism to pick up the machined workpiece 7 from the feeding trolley 5.

[0067] After the truss manipulator removes the workpiece 7, it activates the moving mechanism to send the workpiece 7 to the preset storage area or the input port of the next process, completing the entire work process.

[0068] Through the above work steps, the necking spinning machine can efficiently and precisely complete the hot spinning process of the workpiece 7, meeting the processing requirements of workpieces 7 such as large-diameter and long-size gas cylinders. At the same time, the coordinated work and precise control of each component also ensure the stability and reliability of the processing process.

[0069] In this application, the hollow spindle 9 rotates driven by a motor, and the double-head clamp 8 is arranged on the hollow spindle 9, which can hold the workpiece 7 and rotate with the spindle. This setting not only improves the clamping stability but also realizes the firm clamping of the workpiece 7 through the double-head clamp 8, ensuring that the workpiece 7 will not loosen or shift during the processing.

[0070] In this application, the servo motor and the transmission lead screw drive the clamp adjustment seat to move axially on the headstock, thereby adjusting the position of the double-head clamp 8 on the hollow spindle 9. This setting enables the equipment to adapt to the automatic clamping requirements of workpieces 7 with different diameters, improving the production flexibility and efficiency.

[0071] The left support 1 for the workpiece and the right support 15 for the workpiece are respectively installed on the corresponding bases, and the feeding trolley 5 can move up and down driven by the oil cylinder. This setting makes the workpiece 7 more stable during the pushing and clamping processes, reducing the clamping difficulty caused by the weight and size of the workpiece 7.

[0072] The feeding trolley 5 is equipped with a photoelectric sensor, a mechanical positioning pin, and a positioning control system, which can automatically identify and accurately position the workpiece 7, ensuring the accurate docking of the workpiece 7 with the spindle clamp and further improving the clamping stability and processing accuracy.

[0073] The torch ignites to heat the workpiece 7 to the processing temperature to prepare for the spinning process, and the double-head cutter wheel can perform precise spinning processing at both ends of the workpiece 7. The processing position is adjusted through the moving mechanism to ensure the processing accuracy.

[0074] The setting of the double-head cutter wheel enables the machine to complete the processing of both ends of the workpiece 7 in one clamping, reducing the clamping times and auxiliary time and improving the processing efficiency.

[0075] The cutter wheel seat 11 is provided with a fine adjustment mechanism. By rotating the screw rod, the cutter wheel seat 11 is displaced on the guiding slide rail, and the position sensor monitors the position information in real time. This setting enables the machine to adapt to the processing requirements of workpieces 7 with different lengths, improving the processing flexibility and accuracy.

[0076] The upper sliding table 12 is provided with a locking mechanism, which realizes the quick locking and fixing of the cutter wheel seat 11 through a pneumatic chuck and a locking pin. This setting improves the stability during the machining process and ensures that the machining accuracy is not affected.

[0077] After the machining is completed, the left and right workpiece supporting brackets extend to hold the workpiece 7 by clamping the ejector plate. After the double-head fixture 8 is loosened, the workpiece 7 is taken out of the machining area. The feeding trolley 5 moves under the workpiece 7 and rises to catch the workpiece 7, completing the blanking operation. This setting makes the blanking process stable and orderly, avoiding damage to the workpiece 7 during the movement.

[0078] After receiving the material taking instruction, the truss manipulator moves above the feeding trolley 5 to take away the machined workpiece 7 and sends it to the preset storage area or the input port of the next process. This setting realizes the optimization of the automatic material taking and feeding process and improves the overall production efficiency.

[0079] In the present invention, the spindle fixture and the auxiliary mechanism are integrated on the main body of the machine, reducing the connection and transmission links between components and simplifying the overall structure. This setting reduces energy loss and transmission time, enabling the spinning machine to respond more quickly to machining instructions, thus significantly improving the machining efficiency.

[0080] The auxiliary mechanism drives the workpiece supporting brackets to move left and right through an oil cylinder, cooperating with the lifting movement of the feeding trolley 5, realizing the precise positioning and stable support of the workpiece 7. This automated process reduces manual intervention and shortens the feeding and positioning time, significantly shortening the machining cycle.

[0081] The locking mechanism on the upper sliding table 12 uses a pneumatic control system to drive the pneumatic chuck and the locking pin, which can quickly lock and release the cutter wheel seat 11. This setting simplifies the process of changing products and reduces the time for changing products, enabling the spinning machine to adapt to the machining requirements of different workpieces 7 in a shorter time, thus improving the production efficiency.

[0082] The fine adjustment mechanism on the cutter wheel seat 11 of the present invention allows precise displacement adjustment by rotating the screw to adapt to the machining requirements of workpieces 7 with different lengths. The real-time monitoring and feedback mechanism of the position sensor ensure the accuracy and stability of the position of the cutter wheel seat 11. This fine adjustment ability enables the spinning machine to make fine adjustments during the machining process, thus significantly improving the machining accuracy.

[0083] The spindle fixture drives the hollow spindle 9 to rotate through a motor, and at the same time, the double-head fixture 8 firmly clamps the workpiece 7. This clamping method reduces vibration and offset during the machining process, ensuring the stability of the workpiece 7 during the machining process. The stable clamping and rotation enable the spinning machine to control the machining process more precisely, thus improving the machining accuracy.

[0084] The main body of the machine is slidably arranged, and each component can be flexibly adjusted in position to meet different processing requirements. This arrangement improves the rigidity and stability of the whole machine, enabling the spinning machine to resist external interference and vibration during the processing, thus maintaining a stable processing state.

[0085] The locking mechanism on the upper sliding table 12 can quickly insert into the locking hole to fix the cutter wheel seat 11, preventing it from moving or vibrating during the processing. This arrangement further enhances the processing stability, enabling the spinning machine to maintain stable performance during high-speed rotation and processing.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
