Description

Technical Field

[0001] This utility model relates to the field of piston rod processing technology, and in particular to a cutting device for piston rod processing. Background Technology

[0002] The piston rod is a moving component with frequent and high technical requirements, primarily serving to transmit the force acting on the piston and drive its movement. Piston rods are widely used in hydraulic and pneumatic systems, engineering machinery, automotive manufacturing, plastics machinery, packaging machinery, printing machinery, textile machinery, conveying machinery, and many other fields. The main process in piston rod machining involves cutting the piston rod, and for turning, a CNC lathe is used to complete the turning of the piston rod's end face and sides.

[0003] When machining piston rods on a CNC lathe, a clamping structure is used to hold and fix the semi-finished piston rod, and then the turning operation is performed using a cutting tool. However, existing CNC lathes cannot directly collect and process the chips during the turning process. The chips from the turning process fall directly into the lathe and need to be cleaned manually and regularly to prevent them from affecting the normal operation of related structures. This requires manual operation, which is time-consuming and labor-intensive. Utility Model Content

[0004] The main objective of this invention is to provide a cutting device for piston rod machining, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cutting device for processing piston rods includes a device body, a three-jaw chuck on the device body, a mounting base inside the device body, a tool holder fixed on the mounting base, a material collection structure on the mounting base, and an auxiliary fixing frame inside the device body.

[0007] Preferably, the lower end of the device body is provided with a base, and the device body is provided with a movable door, and a controller is installed on the device body.

[0008] Preferably, the auxiliary fixing frame is provided with a cylinder and a clamping block, and the clamping block on the auxiliary fixing frame is arranged coaxially with the three-jaw chuck.

[0009] Preferably, the material collection structure includes a material collection hood, a clearance hole, a discharge pipe, a mounting base, a threaded joint, a plastic spray pipe, a mounting connector, a connecting pipe, and a locking connecting block. The clearance hole is formed on the material collection hood, and the material collection hood is fixedly connected to the discharge pipe. The material collection hood and the discharge pipe are in communication. The mounting base is fixedly connected to the material collection hood and the discharge pipe, and the mounting base is mounted on the mounting seat by screws. The lower end of the discharge pipe passes through the mounting seat.

[0010] Preferably, the threaded connector is located at the top of the material collection hood, and the threaded connector has a groove. The plastic nozzle and the mounting connector are fixedly connected, and the plastic nozzle is located inside the material collection hood. The mounting connector passes through the top of the material collection hood and the threaded connector. The connecting pipe is connected to the mounting connector, and the locking connecting block is threadedly connected to the threaded connector.

[0011] Compared with the prior art, the present invention has the following advantages: The cutting device for piston rod processing, through the set material collection structure, the material collection hood is fixed on the mounting base by the mounting frame, and a clearance hole is opened on the material collection hood. Without affecting the movement of the tool, the material collection hood can collect debris and coolant, avoiding debris falling into the main body of the device and requiring regular cleaning, thus saving manpower and resources.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a cutting device for piston rod machining includes a main body 1, a three-jaw chuck 2 mounted on the main body 1, a mounting base 3 inside the main body 1, a tool holder 4 fixed on the mounting base 3, a material collecting structure 5 on the mounting base 3, and an auxiliary fixing frame 6 inside the main body 1. A base 7 is located at the lower end of the main body 1, and a movable door 8 is provided on the main body 1. A controller 9 is mounted on the main body 1. A cylinder and a clamping block are mounted on the auxiliary fixing frame 6, and the clamping block on the auxiliary fixing frame 6 is coaxially arranged with the three-jaw chuck 2.

[0019] When machining the piston rod using a cutting device, for the turning of the piston rod, a CNC lathe is used. First, the material collection structure 5 is installed on the mounting base 3. The lower end of the material collection structure 5 passes through the mounting base 3 and is connected to the recycling box inside the base 7, while the upper end of the material collection structure 5 is connected to the coolant delivery pipe. When turning the end face of the piston rod, the piston rod is clamped and fixed using a three-jaw chuck 2. A suitable tool is installed on the tool holder 4. After the device is started using the controller 9, the three-jaw chuck 2 rotates with the piston rod, and the mounting base 3 moves with the tool holder 4 and the tool closer to the piston rod, thus performing the turning of the piston rod. When machining the side of the piston rod, after clamping and fixing the piston rod using the three-jaw chuck 2, the cylinder on the auxiliary fixing frame 6 can be activated. The cylinder drives the clamping block to move, so that the clamping block abuts against the end of the piston rod, which can increase the stability of the piston rod and ensure the accuracy of the turning process. During the machining of the piston rod, the movable door 8 can be closed to make the machining take place in a closed environment, avoiding interference from external factors and improving safety. During machining, the parts of the tool and piston rod being machined are located in the material collection structure 5. Coolant enters the material collection structure 5 through the delivery pipe to cool the tool and piston rod. The machined debris, along with the coolant, falls from the lower end of the material collection structure 5 into the recycling box inside the base 7.

[0020] According to the above implementation scheme, the material collection structure 5 includes a material collection hood 501, a clearance hole 502, a discharge pipe 503, a mounting base 504, a threaded joint 505, a plastic spray pipe 506, a mounting connector 507, a connecting pipe 508, and a locking connecting block 509. The clearance hole 502 is opened on the material collection hood 501, and the material collection hood 501 is fixedly connected to the discharge pipe 503. The material collection hood 501 and the discharge pipe 503 are connected. The mounting base 504 is fixedly connected to the material collection hood 501 and the discharge pipe 503, and the mounting base 504 is installed on the mounting seat 3 by screws. The lower end of the discharge pipe 503 passes through the mounting seat 3. A threaded connector 505 is located at the top of the collecting hood 501 and has a groove. A plastic nozzle 506 and a mounting connector 507 are fixedly connected. The plastic nozzle 506 is located inside the collecting hood 501. The mounting connector 507 passes through the top of the collecting hood 501 and the threaded connector 505. A connecting pipe 508 is connected to the mounting connector 507. A locking connecting block 509 is threadedly connected to the threaded connector 505.

[0021] When installing the material collection structure 5, the discharge pipe 503 and the material collection cover 501 are installed and fixed by the mounting base 504 and screws. The discharge pipe 503 passes through the mounting base 3 and connects to the recycling box in the base 7. A plastic nozzle 506 is set inside the material collection cover 501. The mounting connector 507 at the upper end of the plastic nozzle 506 passes through the threaded connector 505. A locking connector 509 is installed on the threaded connector 505. Under the action of the locking connector 509, the threaded connector 505 deforms through the groove, thereby clamping and fixing itself on the mounting connector 507. Then, the connecting pipe 508 is connected to the conveying pipe, and the plastic nozzle 506 is adjusted so that its end is directly facing the position of the cutting tool. Then it can be used. During turning, coolant enters the plastic nozzle 506 through the delivery pipe, connecting pipe 508, and mounting connector 507, and is finally sprayed out from the plastic nozzle 506, thereby cooling the cutting tool and piston rod. At the same time, the cutting debris, along with the coolant, falls to the bottom of the collection hood 501, and then enters the recovery box through the discharge pipe 503. This achieves rapid collection of debris and coolant, avoiding debris falling into the interior of the main body 1 and requiring subsequent special cleaning, thus saving manpower and resources.

[0022] It should be noted that, through the set material collection structure 5, the material collection cover 501 is fixed on the mounting base 3 by the mounting frame 504. A clearance hole 502 is opened on the material collection cover 501. Without affecting the movement of the cutting tool, the material collection cover 501 can be used to collect debris and coolant, avoiding debris falling into the main body 1 and requiring regular cleaning, thus saving manpower and resources. A plastic nozzle 506 is set inside the material collection cover 501, which can be connected to the cooling pipe to spray coolant without affecting the cooling effect. A threaded joint 505 is set at the upper end of the material collection cover 501, which is used in conjunction with the mounting connector 507 and the locking connector 509. This allows the plastic nozzle 506 to be used both inside the material collection cover 501 and when the material collection cover 501 is not set on the mounting base 3, which provides high flexibility and adaptability.
