Description

Technical Field

[0001] The utility model relates to the technical field of machining of mechanical parts, and more specifically, it relates to a cutting device for machining mechanical parts. Background Technique

[0002] In the existing technology, the traditional way to adjust the tool rest usually requires the operator to manually adjust it. This process may involve multiple steps, such as loosening the fixing bolts, adjusting the angle of the tool rest, and tightening the bolts again. This adjustment method is not only laborious but also time-consuming, especially when it is necessary to frequently adjust the angle of the tool rest to meet different machining requirements. In addition, manual adjustment is often difficult to meet the high-precision requirements, which may affect the accuracy and quality of the machined parts.

[0003] There are also problems of high labor intensity and low efficiency in the installation process of the cutting tool of the existing cutting device. Installing the cutting tool usually requires the operator to use specific tools, such as wrenches, screwdrivers, etc., to manually fix the tool on the tool holder.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a cutting device for machining mechanical parts, which has the following beneficial effects:

[0017] 1. The design of the turret rotation mechanism allows users to achieve quick and precise angle adjustment of the turret through the meshing of the external gear ring, secondary gear, and main gear. When the external gear ring rotates, the meshing secondary gear also rotates, driving the main gear to rotate, and finally realizing the rotation of the turret. This design simplifies the process of turret angle adjustment, improves the adjustment speed and accuracy, and reduces the labor intensity of the operator.

[0018] 2. The design of the quick installation mechanism allows users to achieve quick installation and disassembly of the cutting tool through components such as the clamping rod, clamping block, clamping sleeve, top ring, sliding sleeve, control sleeve, and limit sleeve. When the cutting tool is placed on the turret and connected to the clamping rod through the clamping sleeve, the interaction between the clamping block and the clamping sleeve enables the cutting tool to be quickly and firmly installed. When disassembly is required, by rotating the control sleeve, the coordinated action of the sliding sleeve and the top ring compresses the clamping block, allowing the clamping sleeve to be easily pulled out from the clamping rod, realizing the quick disassembly of the cutting tool. This design greatly improves the installation and disassembly efficiency of the cutting tool, reduces the operation time, and improves the production efficiency.

[0019] 3. The design of the limit fixing mechanism allows users to achieve limit fixing of the turret angle adjustment through the interaction of the connecting ring, limit cylinder, and limit pin. When the turret is adjusted to the appropriate position, align the limit cylinder with the jack on the support plate and insert the limit pin into the limit cylinder to restrict the movement of the external gear ring, thus fixing the turret angle. This design ensures the stability of the turret during the machining process, improves the machining accuracy, simplifies the process of fixing the turret angle, and improves the operation convenience.

[0037] When the cutting tool 8 needs to be installed, the cutting tool 8 is placed on the tool holder 4 through the clamping rod 7, and then the clamping sleeve 10 is inserted into the clamping rod 7. When the clamping block 9 set on the clamping rod 7 contacts the clamping sleeve 10, the slope set on the bottom surface of the clamping sleeve 10 pushes the clamping block 9 into the clamping rod 7 and squeezes the clamping spring 15. When the clamping block 9 moves into the clamping sleeve 10, the bottom end of the clamping sleeve 10 contacts the cutting tool 8, and the clamping spring 15 is reset to pop out the clamping block 9. At this time, the bottom surfaces of multiple groups of clamping blocks 9 are in contact with the clamping sleeve 10, completing the rapid installation of the cutting tool 8. When the cutting tool 8 needs to be disassembled, the control sleeve 13 is rotated to drive the control rod 19 and the limit block 21. The sliding block 20 set on the control rod 19 slides along the sliding groove 18, and the limit block 21 slides along the limit rod 22 and presses the clamping spring 15. The positioning spring 23 is squeezed. When the sliding block 20 disengages from the sliding groove 18, the sliding sleeve 12 is pressed downward to drive the top ring 11 to slide along the giving way groove 17, so that the inclined slope set on the bottom surface of the top ring 11 presses the block 9 and pulls the clamping sleeve 10 upward. When the top ring 11 completely presses the block 9 into the clamping rod 7, the clamping sleeve 10 can be disengaged from the abutment of the block 9, so that the clamping sleeve 10 is disengaged from the clamping rod 7, and the cutting knife 8 is pulled out of the clamping rod 7, and the quick disassembly of the cutting knife 8 can be completed. When it is necessary to adjust the angle of the tool holder 4, the outer gear ring 6 is rotated, and the outer gear ring 6 is meshed with multiple groups of slave gears 5 to drive multiple groups of slave gears 5 to rotate, and the multiple groups of slave gears 5 are meshed with the main gear 3 to drive the main gear 3 to rotate, and the main gear 3 drives the tool holder 4 to rotate, and the use angle of the tool holder 4 can be adjusted.

[0039] See also Figure 2 As an implementation method of a cutting device for machining mechanical parts for a limiting and fixing mechanism: a limiting and fixing mechanism is arranged on the outer gear ring 6, and the limiting and fixing mechanism includes a connecting ring 24, a limiting cylinder 25 and a limiting pin 26. The connecting ring 24 is arranged at the bottom end of the outer gear ring 6 and is rotatably connected to the support plate 2. The limiting cylinder 25 is provided with multiple groups installed on the outer wall of the outer gear ring 6. The limiting pin 26 is arranged in the limiting cylinder 25 and extends into the support plate 2.

[0041] In summary, when the overall equipment is in use or running: when the cutting blade 8 needs to be installed, the cutting blade 8 is placed on the tool holder 4 through the clamping rod 7, and then the clamping sleeve 10 is inserted into the clamping rod 7. When the clamping block 9 set on the clamping rod 7 contacts the clamping sleeve 10, the slope set on the bottom surface of the clamping sleeve 10 pushes the clamping block 9 into the clamping rod 7 and squeezes the clamping spring 15. When the clamping block 9 moves into the clamping sleeve 10, the bottom end of the clamping sleeve 10 contacts the cutting blade 8, and the clamping spring 15 is reset to pop out the clamping block 9.

The sliding block 20 set on the control rod 19 slides along the sliding groove 18, and the limit block 21 moves along the limit rod 22. When the sliding block 20 is disengaged from the sliding groove 18, the sliding sleeve 12 is pressed downward to drive the top ring 11 to slide along the giving way groove 17, so that the inclined slope set on the bottom surface of the top ring 11 presses the card block 9 and pulls the clamping sleeve 10 upward. When the top ring 11 completely presses the card block 9 into the clamping rod 7, the clamping sleeve 10 can be disengaged from the abutment of the card block 9, so that the clamping sleeve 10 is disengaged from the clamping rod 7, and the cutting knife 8 is pulled out of the clamping rod 7. The quick disassembly of the cutting knife 8 can be completed. When the angle of the tool holder 4 needs to be adjusted, the outer gear ring 6 is rotated, and the outer gear ring 6 is meshed with multiple groups of slave gears 5 to drive multiple groups of slave gears 5 to rotate. Through multiple groups of slave gears 5 and the main gear 3, the main gear 3 is driven to rotate, and the main gear 3 drives the tool holder 4 to rotate, and the use angle of the tool holder 4 can be adjusted.
