[0001] The invention belongs to the technical field of bicycle pipe turning, and in particular relates to a cutting device for manufacturing and processing bicycle parts. Background Art

[0002] The bicycle industry is a comprehensive sector encompassing design, manufacturing, sales, maintenance, and related services. In recent years, with growing environmental awareness, the prevalence of healthy lifestyles, and increasing urban traffic pressure, the bicycle industry has continued to grow globally, with electric bicycles and shared bikes performing particularly well.

[0003] The design and manufacture of bicycles are inseparable from the use of lathes to turn pipe fittings, and then the pipe fittings can be welded to form the main frame of the bicycle. However, after the pipe fittings are turned and cut by lathes, burrs will appear on the cut ends of the pipe fittings to a greater or lesser extent, which is not conducive to the subsequent welding between pipe fittings or the socketing between inner and outer pipes. Currently, most workers use handheld angle grinders to remove burrs during later welding activities. This not only greatly reduces the efficiency of subsequent assembly, but also has the problem of inconsistent standards for manual deburring, which easily leads to a decrease in the yield rate of assembled bicycles.

Then, the main shaft is used to drive the clamping piece to rotate at high speed, thereby achieving the purpose of removing the external burrs of the cut end of the pipe.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] Reference Figure 1-Figure 7 As shown, the present invention provides a cutting device for manufacturing and processing bicycle parts, including a machine table 1, a spindle box 2, a spindle 3, a clamping member 4, a tool holder 5, a turning tool body 6 and a coolant pipe 7. The spindle box 2 is fixed on the machine table 1, and the spindle 3 is installed on the output end of the spindle box 2; the clamping member 4 is a clamping claw design and is provided with at least three claws. The clamping claws can be clamped by the cylinder built into the spindle 3. The specific working principle and the like are not described here in detail. They are common knowledge and conventional techniques of technicians in the field. The turning tool body 6 can be tightened by fastening bolts. The coolant pipe 7 is detachably mounted at the lower end of the tool holder 5, and is arranged next to the turning cutter body 6. The upper end of the coolant pipe 7 extends upward and penetrates the tool holder 5 for cooling when the turning cutter body 6 turns and cuts the pipe. The tool holder 5 is connected to the output end of the feed box, which is used to control the feed speed and direction of the tool holder 5 to achieve automatic feeding. The feed amount is adjusted by a gear mechanism or a CNC system to ensure machining accuracy. Specifically, the clamping member 4 is used to clamp and fix the pipe to be machined, and then the spindle box 2 is started to drive the spindle 3 to rotate. The main shaft 3 rotates to drive the clamping part 4 to rotate, the feed box controls the tool holder 5 to descend, drives the turning tool body 6 to descend, and cooperates with the coolant sprayed from the coolant pipe 7 to cut the clamping part 4 to a preset length. It also includes: a retracting component 8, which is composed of a folding part 81 and a flip part 82. The side of the tool holder 5 facing away from the coolant pipe 7 is equipped with a first slide rail 51 for the folding part 81 to move horizontally in the vertical direction; the internal and external deburring component 9 is installed on the flip part 82, and includes an auxiliary frame 91. The end of the auxiliary frame 91 facing away from the flip part 82 is opened. A strip-shaped opening 911 is provided, and a cutting piece 95 is rotatably connected to the strip-shaped opening 911 via a torsion piece 92, and a second sliding piece 94 for controlling the inclination angle of the cutting piece 95 is movably provided outside the auxiliary frame 91. In this way, by adjusting the position of the second sliding piece 94 outside the auxiliary frame 91, the inclination angle of the outer protrusion of the cutting piece 95 relative to the auxiliary frame 91 can be adjusted through the abutment effect, so that the cutting piece 95 is pressed against the inner / outer wall of the cut end of the pipe, thereby achieving the purpose of removing the internal and external burrs of the pipe ends after different turning processes;

[0050] The internal and external deburring assembly 9 is flipped 180 degrees by the flipping member 82, and the second sliding member 94 is used to adjust the inclination of the abutting member 95, so that the internal and external burrs of the ends of the pipes after different turning processes can be adaptively removed.

[0051] In a further embodiment, referring to Figure 4-Figure 6The folding member 81 includes a vertical displacement seat 811 slidably mounted in the first slide rail 51, a folding plate 814 is rotatably connected to the side groove of the vertical displacement seat 811 through a rotating shaft 813, a first sliding member 815 is slidably mounted on the side of the folding plate 814, and the first sliding member 815 is arranged to intersect the folding plate 814 perpendicularly; a rotation hole is opened in the middle of the first sliding member 815, and the flip member 82 is installed in the rotation hole of the first sliding member 815, and the first flip cylinder 812 drives the rotating shaft 81 3 rotation, the folding plate 814 can be folded into the side groove of the vertical moving seat 811. Conversely, the first flip cylinder 812 drives the rotating shaft 813 to rotate in the opposite direction, so that the folding plate 814 folded in the side groove of the vertical moving seat 811 can be flattened outward, making it easier to lower the flip member 82 and the internal and external deburring assembly 9. The first flip cylinder 812 is fixedly installed on the lower end side of the vertical moving seat 811, and the exposed end of the rotating shaft 813 is fixedly connected to the output end of the first flip cylinder 812.

[0052] The flipping member 82 includes a rotating disk 821 rotatably installed in the rotating hole, a fixing frame 822 is fixedly installed on the end face of the rotating disk 821, and the internal and external deburring assembly 9 is arranged in the fixing frame 822; the first sliding member 815 is installed on the side facing away from the rotating disk 821 with a second flipping cylinder 823 that matches the rotating disk 821 and can drive the rotating disk 821 to rotate.

[0053] In this embodiment, when it is necessary to deburr the cut end of the pipe fitting, the folding and retracting piece 81 is unfolded and the flipping piece 82 is put down. Before turning and cutting a new pipe fitting again, in order to avoid interference of the retracting and retracting component 8 and the internal and external deburring component 9 with the turning and cutting, the folding and retracting component 8 needs to be retracted again to leave working space for the turning and cutting of the coolant pipe 7; and the second flipping cylinder 823 is used to drive the rotating disk 821 to rotate one hundred and eighty degrees, and the internal and external deburring component 9 is flipped, so that the purpose of the internal and external deburring component 9 to remove the internal / external burrs of the cut surface of the pipe fitting in turn can be achieved.

[0054] In a further embodiment, referring to Figure 6-Figure 8The auxiliary frame 91 is fixedly installed between the fixed frames 822, and the torsion member 92 includes a pin shaft 921 rotatably inserted in the strip opening 911, and the pin shaft 921 passes through the abutment member 95. Both ends of the pin shaft 921 are fixedly sleeved with a mounting ring 922, and both ends of the pin shaft 921 are respectively sleeved with a torsion spring 923 set against the end faces of the two mounting rings 922; the two ends of the torsion spring 923 are respectively fixedly connected to the end faces of the adjacent torsion spring 923 and the side face of the auxiliary frame 91; the second sliding member 94 includes a sliding frame body 941, and two second slide rails 93 are symmetrically installed on the side of the auxiliary frame body 91. The sliding frame body 941 is slidably installed on the two second slide rails 93, and a rolling column 942 is rotatably installed on the side of the sliding frame body 941 facing away from the two second slide rails 93, and the outer wall of the rolling column 942 is set against the side of the oblique pressure rod 951;

[0055] The anti-cutting part 95 includes an inclined pressure rod 951 and two anti-cutting pieces 952. The two anti-cutting pieces 952 are respectively located on both sides of the end of the inclined pressure rod 951 facing away from the rotating disk 821; the two anti-cutting pieces 952 are installed on the end of the inclined pressure rod 951 through quick-release bolts; the anti-cutting pieces 952 are made of cemented carbide, specifically tungsten carbide material, suitable for high-speed deburring, and the quick-release bolts facilitate the quick replacement of the ground anti-cutting pieces 952 to ensure the deburring processing capability of the device.

[0056] The second slide 94 is moved horizontally to the end away from the rotating disk 821, and the rolling support column 942 in the second slide 94 pushes the inclined pressure rod 951, causing the end of the inclined pressure rod 951 equipped with the anti-cutting piece 952 to deflect and rotate, and finally causes the anti-cutting piece 952 to press against the inner wall of the cut end of the pipe; another embodiment is: the second turning cylinder 823 is used to drive the rotating disk 821 to rotate 180 degrees, and the internal and external deburring assembly 9 is turned over, and then the position of the tool holder 5 is adjusted in conjunction with the feed box, so that the anti-cutting piece 95 is close to the cut end of the pipe, and the second slide 94 is moved horizontally to the end away from the rotating disk 821, and the rolling support column 942 in the second slide 94 pushes the inclined pressure rod 951, causing the end of the inclined pressure rod 951 equipped with the anti-cutting piece 952 to deflect and rotate, and finally causes the anti-cutting piece 952 to press against the outer wall of the cut end of the pipe.

[0057] The working principle of the present invention is as follows: first, the clamping member 4 can be used to clamp and fix the pipe to be processed. Then, the spindle box 2 is started to drive the spindle 3 to rotate. The rotation of the spindle 3 drives the clamping member 4 to rotate. The feed box controls the tool holder 5 to descend, driving the turning tool body 6 to descend. The coolant sprayed from the coolant pipe 7 is used to cut the clamping member 4 to a preset length, and the cut pipe falls down.

[0058] After that, the spindle 3 stops rotating temporarily, the tool holder 5 is lifted up and away from the pipe fitting, the vertical shift seat 811 moves down in the first slide rail 51, and then the first flip cylinder 812 drives the rotating shaft 813 to rotate, causing the folding plate 814 folded in the side groove of the vertical shift seat 811 to rotate and lay flat, and then the first sliding member 815 is adjusted to the side close to the turning cutter body 6, and the feed box drives the tool holder 5 to adjust its position, so that the internal and external deburring assembly 9 can be close to the cross-section of the pipe fitting, and then the second sliding member 94 in the internal and external deburring assembly 9 adjusts the inclination angle of the cutting member 95, so that the cross-section of the pipe fitting can be deburred. Among them, the 180-degree flipping of the internal and external deburring assembly 9 by the flip member 82 can ensure that the device can remove the internal and external burrs of the end of the pipe fitting after turning;

[0059] The specific steps for removing the two burrs are as follows: When removing the internal burrs, Figure 2 and Figure 4 、 Figure 5 As shown, after the cutting piece 95 is inserted into the cut end of the pipe, the second sliding member 94 moves horizontally toward the end away from the rotating disk 821, and the rolling support column 942 in the second sliding member 94 pushes the inclined pressure rod 951, causing the end of the inclined pressure rod 951 equipped with the cutting piece 952 to move. Figure 8 As shown, the counterclockwise rotation is performed, and finally the chipping piece 952 is pressed against the inner wall of the cut end of the pipe fitting, and then the main shaft 3 drives the clamping member 4 to rotate at a high speed, so that the burrs inside the cut end of the pipe fitting can be removed; when removing the external burrs, the second turning cylinder 823 is first used to drive the rotating disk 821 to rotate 180 degrees, and the internal and external deburring assembly 9 is turned over to the position shown in FIG. Figure 7 As shown, the position of the tool holder 5 is adjusted in conjunction with the feed box, and the cutting member 95 is pushed close to the cut end of the pipe. The second sliding member 94 is translated toward the end away from the rotating disk 821, and the rolling column 942 in the second sliding member 94 pushes the inclined pressure rod 951, causing the end of the inclined pressure rod 951 equipped with the cutting piece 952 to deflect and rotate, and finally causing the cutting piece 952 to press against the outer wall of the cut end of the pipe. After that, the main shaft 3 is used to drive the clamping member 4 to rotate at high speed, so as to achieve the purpose of removing the burrs on the cut end of the pipe.

[0060] In this way, the turning and cutting of the pipe fittings and the removal of internal and external burrs on the end faces of the cut pipe fittings are integrated into one big step, coordinated in sequence, and a unified standard for burr removal is set. This can greatly improve the assembly efficiency of the pipe fittings in subsequent processing, thereby improving the yield rate of the assembled bicycles.
