Description

Technical Field

[0001] The invention relates to the technical field of mechanical parts processing, and in particular to a cutting device for piston pin production which is easy to adjust. Background Art

[0002] Cutting is a crucial step in the production and processing of piston pins. Traditional piston pin cutting equipment often has problems such as low cutting efficiency, unstable cutting quality and excessive tool wear. These problems are largely caused by the lack of effective cooling and lubrication measures during the cutting process.

[0003] In traditional cutting equipment, the water pipe is usually fixed in a certain position and cannot be adjusted as the cutting tool moves. This design means that during the cutting process, the water pipe cannot continuously and stably cool and lubricate the cutting part. Especially when the cutting tool moves to a position far away from the water pipe, the temperature and friction of the cutting part will rise sharply, which not only affects the cutting efficiency and quality, but also accelerates the wear of the tool.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a cutting device for piston pin production that is easy to adjust, including a processing table 1, a first driving mechanism 3, a second driving mechanism 4, a cutter 5, a moving mechanism 6, a water spray pipe 8 and a positioning mechanism 9. The first driving mechanism 3 is connected to the cutter 5 to drive the cutter 5 to rotate. The positioning mechanism 9 is used to fix the two ends of the piston pin 100. The second driving mechanism 4 is used to drive the piston pin 100 to rotate. The first driving mechanism 3 is connected to the moving mechanism 6. The moving mechanism 6 is used to move along the axial direction of the piston pin 100 on the processing table 1. The water spray pipe 8 is arranged above the processing table 1. The water outlet of the water spray pipe 8 faces the cutter 5, and the water spray pipe 8 is used to move with the moving mechanism 6.

[0027] In this embodiment, through the driving connection between the first driving mechanism 3 and the cutter 5, the device can drive the cutter 5 to rotate, thereby efficiently cutting the piston pin 100. This design ensures the stability and accuracy of the cutting process and improves production efficiency. The setting of the positioning mechanism 9 enables both ends of the piston pin 100 to be firmly fixed, ensuring stability during the cutting process. At the same time, the flexibility of the positioning mechanism 9 also adapts to piston pins 100 of different lengths and specifications, improving the versatility of the device. The introduction of the second driving mechanism 4 enables the piston pin 100 to rotate during the cutting process, thereby achieving comprehensive and uniform processing of the piston pin 100. This rotary cutting method not only improves the cutting quality, but also effectively extends the service life of the cutter 5. The design of the moving mechanism 6 enables the first driving mechanism 3 (and the cutter 5 connected thereto) to move along the axial direction of the piston pin 100 on the processing table 1. This moving method not only facilitates the adjustment of the cutting position, but also enables the device to adapt to piston pins 100 of different lengths, improving the flexibility and convenience of processing. The setting of the water spray pipe 8 plays a role in cooling and lubricating the cutting part. The water outlet faces the cutter 5, and can spray water to the cutting part continuously and stably, reducing the temperature and friction during the cutting process, further improving the cutting efficiency and the service life of the cutter 5. At the same time, the design of the water spray pipe 8 moving with the moving mechanism 6 also ensures the continuity of cooling and lubrication.

[0028] Optionally, the first driving mechanism 3 includes a first driving device 31, a driving pulley 32, a belt 33, a driven pulley 34, a driving shaft 35 and a first support seat 36. The first driving device 31 is connected to the first support seat 36. The output shaft of the first driving device 31 is connected to the driving pulley 32. The driving pulley 32 is connected to the driven pulley 34 through the belt 33. The driven pulley 34 is mounted on one end of the driving shaft 35, and the other end of the driving shaft 35 is connected to the scraper 5.

[0029] In this embodiment, the first driving mechanism 3 is ingeniously designed, and the first driving device 31 (such as a first motor) provides power to drive the driving pulley 32 to rotate. The driving pulley 32 transmits power to the driven pulley 34 through the belt 33, thereby driving the driving shaft 35 to rotate. The other end of the driving shaft 35 is closely connected to the cutting tool 5, ensuring that the rotational power can be accurately transmitted to the cutting tool 5, so that it can efficiently cut the piston pin 100.

[0030] Optionally, the first drive device 31 is configured as a first motor.

[0032] In this embodiment, the structure of the moving mechanism 6 is very stable and flexible. The third driving device 62 (such as a third motor) provides power to drive the gear 63 to rotate. The gear 63 is tightly meshed with the rack 61, so that the entire first driving mechanism 3 and the cutter 5 connected thereto can move smoothly along the axial direction of the piston pin 100. At the same time, the multiple running wheels 64 ensure stability and smoothness during the movement, making the cutting operation more precise and controllable.

[0033] Optionally, the third drive device 62 is configured as a third electric motor.

[0035] In this embodiment, the design of the positioning mechanism 9 fully considers the fixing requirements of the piston pin 100. The first three-grip chuck 91 is connected to the moving seat 93, so that the first three-grip chuck 91 can slide flexibly on the processing table 1 to adapt to different lengths of the piston pin 100. The second three-grip chuck 92 is firmly fixed to the other end of the processing table 1, and together with the first three-grip chuck 91, it forms a stable clamping system to ensure that the piston pin 100 always remains fixed during the cutting process.

The second driving device 42 (such as a second motor) provides power and is connected to the second three-claw chuck 92 through an output shaft to drive the piston pin 100 to rotate. This design allows the piston pin 100 to be evenly stressed during the cutting process, further improving the cutting quality and efficiency. At the same time, the sliding connection design of the second support seat 41 also increases the flexibility of the device, making it easy to adjust according to different needs.

[0040] In this embodiment, the clever design of the follower mechanism 7 enables the water spray pipe 8 to move with the moving mechanism 6. The slider 71 slides on the slide bar 72 and is connected to the first support seat 36 through the linkage rod 73. This connection method ensures that the water spray pipe 8 can always maintain a constant relative position with the cutter 5 during the movement, so that water can be continuously and stably sprayed to the cutting part to play a role in cooling and lubrication. This not only improves the cutting efficiency, but also effectively prolongs the service life of the cutter 5.
