Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of automatic lathes, and in particular, to a double-sided automatic lathe for valve bodies. Background Art

[0002] In the field of mechanical processing, automatic lathes are widely used as equipment that can significantly improve production efficiency and reduce labor costs. As a key component in the field of fluid control, the machining accuracy and production efficiency of valve bodies have a significant impact on the development of the entire industry.

[0003] In the existing technology, the automatic lathe is a high-efficiency automated equipment specially used for processing valve body parts. It is mainly composed of a bed, a processing tool holder, a feed system and an electrical control system. The bed serves as the basic structure of the lathe and provides a stable installation platform for other components. The processing tool holder is used to perform turning, drilling, boring and other processing operations on the end face of the valve body. The feed system controls the precise axial and radial movement of the tool holder. The electrical control system realizes automatic control of the processing process through programming instructions. However, the existing automatic lathes still have the following problems when used for valve body processing. For example, the tools of some automatic lathes can only act on the workpiece at a vertical angle. In actual processing, this not only greatly limits the processing flexibility, but also makes it difficult to adapt to the complex shape of the valve body and specific cutting requirements, resulting in a relatively narrow scope of application. In addition, traditional lathes often need to process one side at a time. When one side is processed, other equipment is needed to flip the valve body and then process the other side. This not only increases the use cost and labor cost of the flipping equipment, but also greatly reduces the processing efficiency, which has an adverse effect on the performance of the lathe.

[0025] Among them, the screw rod adjusting part 1 and the screw rod adjusting part 2 are vertically arranged, the screw rod adjusting part 1 and the screw rod adjusting part 2 have the same structure, the screw rod adjusting part 1 and the screw rod adjusting part 2 both include an adjusting screw 9 and an adjusting motor 11, the adjusting screw 9 is rotatably arranged in the tool holder box 1 2 or the tool holder box 2 6, and an adjusting ball nut 10 is transmitted on the adjusting screw 9, the adjusting ball nut 10 group is connected to the tool holder box 2 6 or the L-shaped adjusting plate 7, the adjusting motor 11 is installed on one side of the tool holder box 1 2, and the output end of the adjusting motor 11 is connected to one end of the adjusting screw 9.

[0026] Specifically, the positioning motor 11 is started, and the output end of the positioning motor 11 can drive the positioning screw 9 to rotate, which can enable the positioning ball nut 10 group to perform linear motion on the positioning screw 9. Through the vertical setting of the screw positioning part 1 and the screw positioning part 2 in the three-axis positioning component 001, the positioning motor 11 drives the driving positioning screw 9 to rotate, and the positioning ball nut 10 can drive the tool holder box 2 6 and the L-shaped positioning plate 7 to perform precise X and Y axis movement, and the vertical adjustment cylinder 1 8 can realize the precise fine-tuning of the valve body processing component 002 in the Z axis direction, thereby realizing high-precision control of the processing position and meeting the precision requirements of complex valve body processing.

[0027] As mentioned above, there are two bogies 3, and the bogies 3 correspond one-to-one to the three-axis positioning assembly 001. Each bogie 3 is set on the three-axis positioning assembly 001 through a valve body processing assembly 002 that can drive the bogie 3 to rotate. The valve body processing assembly 002 includes a transfer frame 12, a transfer motor 13 and a processing motor 15. The transfer frame 12 is set on the output end of the longitudinal adjustment cylinder 8, and the transfer motor 13 is installed in the transfer frame 12. The bogie 3 is set on the output end of the transfer motor 13, and the processing motor 15 is installed in the bogie 3. The output end of the processing motor 15 is provided with a three-jaw chuck 16, and a processing tool head 17 is detachably provided in the three-jaw chuck 16.

[0028] Specifically, start the transfer motor 13, and the output end of the transfer motor 13 can drive the bogie 3 to rotate, and the rotation of the bogie 3 can drive the processing motor 15 to rotate, and the rotation of the processing motor 15 can drive the processing head 17 to rotate, which can not only realize the angle adjustment of the processing head 17, but also drive the three-jaw chuck 16 and the processing head 17 to rotate by the processing motor 15, so as to complete processing operations of different angles and types. Through the combination of the above-mentioned multiple adjustment methods, the lathe can adapt to the diversified processing requirements of valve bodies of different specifications and shapes, so as to improve the versatility and flexibility of the equipment.

[0029] By symmetrically arranging the tool holder box 2 and the internal three-axis positioning assembly 001 on both sides of the bed body 1, in conjunction with the bogie 3 and the valve body processing assembly 002, not only can the double-sided processing of the valve body be achieved at the same time, but the base drive assembly 003 can also accurately drive the valve body base 4 to rotate. Combined with the double-sided processing, the lathe can quickly complete the cutting, drilling and other processing procedures of various parts of the valve body, further improving the processing efficiency.

[0030] As mentioned above, the valve body base 4 is arranged on the bed body 1 through the base drive assembly 003. The base drive assembly 003 includes a drive shaft 18, a drive worm gear 19, a drive worm 20 and a drive motor 21. The drive shaft 18 passes through and is rotatably arranged in the bed body 1. The valve body base 4 is arranged at one end of the drive shaft 18. The drive worm gear 19 is arranged on the drive shaft 18. The drive worm 20 is rotatably arranged in the bed body 1. The drive worm 20 is engaged with the drive worm gear 19. The drive motor 21 is installed on one side of the bed body 1, and the output end of the drive motor 21 is engaged with one end of the drive worm 20.

[0031] Specifically, the drive motor 21 is started, and the output end of the drive motor 21 can drive the drive worm 20 to rotate, and the rotation of the drive worm 20 drives the drive worm wheel 19 to rotate, and the rotation of the drive worm wheel 19 drives the drive shaft 18 to rotate. The rotation of the drive shaft 18 can drive the valve body base 4 to rotate. By arranging the valve body to be processed on the valve body base 4, the drive motor 21 can drive the valve body to rotate, so as to facilitate the processing of the valve body. When driving the valve body to rotate, the self-locking cooperation of the drive worm 20 and the drive worm wheel 19 can further improve the stability of the valve body during the processing and improve the processing accuracy of the valve body.

[0032] As mentioned above, the valve body limit seat 5 is rotatably set on one side of the bed body 1 through the dual-axis positioning component 004. The valve body limit seat 5 corresponds to the valve body base 4. A valve body positioning cavity is formed between the valve body base 4 and the valve body limit seat 5. The dual-axis positioning component 004 includes a horizontal adjustment cylinder 22, a horizontal adjustment plate 23, a vertical adjustment cylinder 24 and a pressure sensor 25. The horizontal adjustment cylinder 22 is installed in the bed body 1, the horizontal adjustment plate 23 is set on the output end of the horizontal adjustment cylinder 22, the vertical adjustment cylinder 24 is installed on the horizontal adjustment plate 23, the pressure sensor 25 is set on the output end of the vertical adjustment cylinder 24, and the valve body limit seat 5 is rotatably set on the detection end of the pressure sensor 25.

[0033] Specifically, when positioning the valve body to be processed, the valve body to be processed is placed on the valve body base 4. By starting the horizontal adjustment cylinder 22 and the vertical adjustment cylinder 24, the valve body limit seat 5 can be driven to move to the bottom of the valve body base 4, and the valve body to be processed is squeezed by the valve body limit seat 5 to fix the valve body. When fixing the valve body, the pressure of the valve body limit seat 5 on the valve body is monitored in real time by the pressure sensor 25 to ensure that the valve body is firmly fixed and will not be damaged due to excessive pressure, thereby ensuring the stability and reliability of the processing process.

[0034] It is additionally noted that, by providing the horizontal adjustment cylinder 22 , the position of the valve body limit seat 5 can be adjusted, which may facilitate the placement of the valve body parts to be processed.

[0035] As mentioned above, in order to facilitate the inspection of the valve body during the processing, a monitoring camera 26 for observing the processing status of the valve body is installed on one side of the bed body 1. The monitoring camera 26 can observe the processing status of the valve body in real time. The operator can grasp the processing status in time, discover and solve problems that arise during the processing, and ensure the processing quality.

[0036] As mentioned above, in order to facilitate the collection of impurities generated during the valve body processing, a slag collecting rack 27 is also installed on the bed body 1, and the drive shaft 18 is penetrated and rotatably set on the slag collecting rack 27. The slag collecting rack 27 is detachably provided with a slag collecting bucket 28, and the slag collecting bucket 28 is located below the valve body base 4. The setting of the slag collecting rack 27 and the slag collecting bucket 28 is convenient for collecting waste slag such as iron filings generated during the processing, keeping the working environment clean, and facilitating the centralized treatment of waste slag to reduce pollution to the environment, and the detachable slag collecting bucket 28 is easy to clean and maintain.

[0037] When the double-sided automatic lathe for the valve body is in operation, the valve body to be processed is first placed on the valve body base 4. At this time, the horizontal adjustment cylinder 22 and the vertical adjustment cylinder 24 are started, and the valve body limit seat 5 is driven to move to the bottom of the valve body base 4 through the dual-axis adjustment component 004. The valve body limit seat 5 squeezes the valve body to fix it, and the pressure sensor 25 monitors the pressure in real time to ensure that it is firmly fixed and the valve body is not damaged. Subsequently, the drive motor 21 of the base drive assembly 003 is started, and the drive motor 21 drives the drive worm 20 to rotate. Through the engagement of the drive worm wheel 19 and the drive worm 20, the drive shaft 18 is rotated, thereby driving the valve body base 4 and the valve body to rotate. The self-locking cooperation of the drive worm 20 and the drive worm wheel 19 ensures the stability of the valve body during the processing. Then, the three-axis positioning assembly 001 in the tool holder box 2 on both sides starts to operate, and the positioning motor 11 drives the positioning screw 9 to rotate, so that the positioning ball nut 10 moves linearly on the positioning screw 9, and through the vertical setting of the screw rod positioning part 1 and the screw rod positioning part 2, the tool holder box 2 6 and the L-shaped positioning plate 7 are driven to move precisely in the X and Y axis directions, and the longitudinal adjustment cylinder 1 8 realizes the fine adjustment of the valve body processing assembly 002 in the Z axis direction to complete the high-precision positioning of the processing position, and the valve body processing assembly 002 on the bogie 3 works synchronously, and the adjustment motor 13 drives the bogie 3 to rotate, and then drives the processing motor 15 and the processing head 17 to rotate, which can realize the angle adjustment and rotation of the processing head 17 to meet the processing requirements of different angles and types, and the valve body processing assemblies of the tool holder box 2 on both sides work together to realize the simultaneous processing of both sides of the valve body.

[0038] During the machining process, monitoring cameras 26 provide real-time visibility into the valve body's machining status, enabling operators to promptly identify and resolve any issues. Slag collection racks 27 and slag hoppers 28 collect waste, such as iron filings, generated during machining, maintaining a clean work environment and facilitating centralized waste disposal. Throughout the entire process, each component works closely together to achieve efficient and precise machining of the valve body, enhancing the equipment's versatility and flexibility.
