Description

Technical Field

[0001] The invention belongs to the technical field of parts processing, and in particular relates to a processing system with a silencer structure. Background Art

[0002] Shaft parts are an important component of electrical industry products, used for the fixed connection and support of large electrical equipment. CNC lathes are usually used to process shaft parts. CNC lathes are automatic machine tools equipped with program control systems. The control system can logically process programs specified by control codes or other symbolic instructions, and decode them to enable the machine tool to move and process parts. CNC lathes play a vital role in our mechanical manufacturing field.

[0003] At present, CNC lathes do not have a material support device at the tail of the machine tool, which causes the tail end of the long material to fall naturally due to gravity after clamping, and the whole material is in a tilted state. During the operation, the friction between the material and the machine tool will produce a lot of friction and noise, or the whole material will fall out and hurt people, affecting the normal production. After the processing is completed, the material needs to be clamped manually, and the material needs to be pulled out and processed again. This method requires too much manual operation, wastes time, and seriously affects the processing efficiency. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a processing system with a silencer structure, which can avoid the problems of sinking due to gravity of raw materials, excessive friction noise during the processing process, and the escape of raw materials due to centrifugal force. It solves the problem that the labor intensity of shaft parts is too high and prone to danger during CNC processing.

[0005] The present invention is implemented in this way. The present application provides a processing system with a silencer structure, including a CNC lathe, a silencer mechanism is arranged on the feeding side of the CNC lathe, a material pulling robot for pulling shaft parts is arranged on the processing side of the CNC lathe, the shaft parts in the silencer mechanism are parallel to the ground, and pass through the center position of the feeding port of the CNC machine tool and extend into the processing station;

[0006] The silencer mechanism comprises a supporting column, wherein a supporting seat is arranged at the upper end of the supporting column, and a mounting fixture is arranged on the mounting surface of the supporting seat via a shock-absorbing component, wherein a raw material sleeve for the shaft parts to pass through is clamped in the mounting fixture.

[0007] Furthermore, the shock absorbing component includes a fixing bolt, the screw end of which passes through the mounting fixture and the support seat in sequence and is fixed by a nut, a first elastic member is sleeved on the screw between the upper end face of the support seat and the lower end face of the mounting fixture, and a second elastic member is sleeved on the screw between the upper end face of the mounting fixture and the bolt head. By tightening the fixing bolt with the nut, the mounting fixture can be pre-tightened and fixed, and the installation position of the mounting fixture can be adjusted to ensure that the shaft parts in the raw material sleeve remain parallel to the ground and are located at the center of the feed port of the CNC lathe; the first elastic member and the second elastic member both play a role in buffering and shock absorption. During the processing, the vibration and impact force of the machine tool can be effectively absorbed by these elastic members, thereby protecting the mounting fixture, the support seat and the shaft parts from damage.

[0008] Furthermore, the installation fixture includes a clamping part and a mounting part, the mounting part is arranged on both sides of the clamping part, the clamping part is a ring-shaped structure with an opening at the upper end, and the inner diameter of the clamping part is adapted to the outer diameter of the raw material sleeve; the shock absorbing member is arranged on the mounting part. The clamping part is designed as a ring-shaped structure, and the inner diameter is adapted to the outer diameter of the raw material sleeve. This design ensures that the raw material sleeve can be accurately clamped in the installation fixture. This precise clamping method not only improves the stability of processing, but also helps to reduce errors in the processing process.

[0009] Furthermore, a fastening bolt is provided on the clamping part, and the end of the fastening bolt passes through the clamping part and abuts against the outer wall of the raw material sleeve. The fastening bolt can directly act on the outer wall of the raw material sleeve, and by adjusting the tightening degree of the bolt, the raw material sleeve can be tightly clamped. This clamping method is more direct and effective than the traditional clamping method that relies on friction or elastic parts, and can provide greater clamping force, ensure the stability of the raw material sleeve during processing, and ensure the position accuracy of the raw material sleeve in the installation fixture, thereby reducing the processing error caused by shaking or displacement of the raw material sleeve. This high-precision clamping method helps to improve the processing accuracy and finished product quality of shaft parts.

[0010] Furthermore, two mounting fixtures are provided, and the two mounting fixtures are respectively arranged at the two ends of the raw material sleeve along the axial direction of the raw material sleeve. The two mounting fixtures are respectively located at the two ends of the raw material sleeve, providing a more balanced and stable support. This design effectively prevents the raw material sleeve from bending or shaking during the processing, improves the processing stability; and can ensure the straightness and coaxiality of the raw material sleeve during the processing, thereby meeting the requirements of high-precision processing.

[0011] Furthermore, a protective cover is provided on the support seat, the side plate of the protective cover is connected to the side wall of the support seat, the protective cover and the support seat enclose a receiving cavity, and the installation fixture and the raw material sleeve are placed in the receiving cavity. The protective cover provides a relatively closed working environment for the installation fixture and the raw material sleeve, which can effectively prevent the splash, chips or other debris generated during the processing from harming the operator, improve work safety, reduce damage and performance degradation of the equipment due to pollution, and extend the service life of the equipment.

[0012] Furthermore, the outer layer of the raw material casing is a steel pipe, and the inner layer of the raw material casing is nested with a nylon tube. By nesting the nylon tube inside the steel pipe, the high strength characteristics of the steel pipe can be fully utilized to improve the strength and bearing capacity of the entire raw material casing. The steel pipe can withstand greater external pressure and impact force, and protect the inner nylon tube from damage. This design of combining inside and outside enables the raw material casing to maintain structural integrity and stability when subjected to heavy pressure. Nylon tubes are known for their excellent wear resistance. Nesting inside the steel pipe can effectively extend the service life of the entire raw material casing. In situations where frequent movement or friction is required, this wear resistance is particularly important, and can significantly reduce downtime and maintenance costs caused by wear; and the nylon tube has a certain damping performance, which can absorb and disperse vibration and noise. Therefore, in situations where noise and vibration need to be reduced, the inner nylon tube of the raw material casing can provide effective help and improve the working environment and conditions.

[0013] The advantages and technical effects of the present invention are as follows: Due to the adoption of the above-mentioned technical solution, the problems of sinking of raw materials due to gravity, excessive friction noise during the processing, and the escape of raw materials due to centrifugal force are avoided. The problem of excessive manual labor intensity and easy danger in the CNC processing of shaft parts is solved. Through the linkage between the material pulling robot and the CNC lathe, and the auxiliary protection support of the silencer mechanism, the entire processing process can be unmanned. The robot completes the material pulling through instructions, sends a signal, and the CNC lathe starts processing. After the processing is completed, the robot continues to pull the material, and then the processing is fully automatically cyclically performed. The use of the processing system of this application can greatly reduce manual operation, thereby improving efficiency and ensuring safety.

[0014] The cooperation between the silencer mechanism and the manipulator ensures the straightness and stability of shaft parts during the processing, avoids the failure of the raw materials to reach the accurate stretching size due to the weight tilt, reduces the processing error caused by the tilt of the raw materials, and thus improves the processing accuracy and finished product quality of shaft parts. By setting the support column and the support seat, additional support points are provided for the long shaft raw materials, which effectively prevents the tilting phenomenon caused by the natural fall of the raw materials due to gravity during the processing. This not only reduces unnecessary friction between the raw materials and the machine tool, reduces noise pollution, but also avoids safety accidents that may be caused by shaking or falling out of the raw materials, and improves the stability and safety of the overall processing process.

During the processing, the vibration and impact force of the machine tool can be effectively absorbed by these elastic members, thereby protecting the mounting fixture 7, the support seat 5 and the shaft parts 9 from damage.

[0025] Furthermore, the installation fixture 7 includes a clamping portion 7-1 and a mounting portion 7-2, wherein the mounting portion 7-2 is arranged on both sides of the clamping portion 7-1, and the clamping portion 7-1 is a ring-shaped structure with an opening at the upper end, and the inner diameter of the clamping portion 7-1 is adapted to the outer diameter of the raw material sleeve 8; the shock absorbing member 6 is arranged on the mounting portion 7-2.

This design of combining inside and outside allows the raw material casing 8 to maintain structural integrity and stability when subjected to heavy pressure. Nylon tubes are known for their excellent wear resistance. Nesting inside the steel pipe can effectively extend the service life of the entire raw material casing 8. In situations where frequent movement or friction is required, this wear resistance is particularly important, and can significantly reduce downtime and maintenance costs caused by wear; and the nylon tube has a certain damping performance, which can absorb and disperse vibration and noise.

Through the motion program, the material pulling robot 3 realizes material pulling.
