Moreover, the entire lifting frame 300 or the entire set of drills 400 does not need to be replaced because of the problem of the individual drill 400, only the damaged part needs to be replaced, and the use cost and maintenance cost of the equipment are reduced.

[0042] In actual production, different specifications of drills 400 can be replaced according to the drilling requirements of different bicycle frames, the universality and adaptability of the device are increased, and various processing requirements are met.

[0043] Further, the drill 400 is slidably arranged on the lifting frame 300, and the drill 400 is close to or far from each other after sliding.

For bicycle frame drilling of the same hole diameter and different hole spacings, a special drilling device does not need to be provided for each specific spacing of the bicycle frame, and by slidingly adjusting the spacing between the drill tools 400, one device can be adapted to the machining of multiple different models of bicycle frames, thereby reducing equipment cost and production investment.

[0045] Further, the drill tool 400 has a drill bit 410 at one end, the drill bit 410 is used for drilling, the drill tool 400 has a mounting rod 420 at the end away from the drill bit 410, the mounting rod 420 has a boss 421, and the mounting rod 420 has an external thread at the end away from the drill bit 410, and further comprising a fixed plate 500 arranged on the lifting frame 300, the fixed plate 500 has a plurality of sliding grooves, the mounting rod 420 passes through the sliding grooves, and the boss 421 is located on the side of the fixed plate 500 close to the drill bit 410; the top ring 600 has a thread, the top ring 600 is threadedly connected with the mounting rod 420, the top ring 600 is close to or away from the boss 421 after being rotated, a first clamping space 610 is formed between the top ring 600 and the boss 421, and the fixed plate 500 is located in the first clamping space 610.

[0046] In the embodiment, the first clamping space 610 is formed by the cooperation of the top ring 600 and the boss 421 to clamp the fixed plate 500, so that the position of the drill tool 400 on the lifting frame 300 can be stably fixed, not only the drill tool 400 can be ensured not to shake or displace during drilling, thereby improving the precision and quality of drilling, but also the boss 421 always abuts against one side of the fixed plate 500, ensuring the consistency of the mounting position of the drill tool 400 and the straightness of the plurality of drill tools 400.

[0047] The mounting rod 420 passes through the sliding grooves of the fixed plate 500 and is threadedly connected with the top ring 600, so that the position adjustment of the drill tool 400 is simple and fast. The clamping and loosening between the drill tool 400 and the fixed plate 500 can be realized by only rotating the top ring 600, the spacing between the drill tools 400 can be easily changed, and different drilling requirements can be adapted.

[0048] Further, the sliding rod 700 has a plurality of sliding rods 700, one end of each of the plurality of sliding rods 700 is slidingly arranged on the lifting frame 300, the other end of each two sliding rods 700 abuts against the two sides of one drill tool 400, and the sliding rod 700 is used for preventing the drill tool 400 from rotating.

[0049] In this embodiment, the sliding rod 700 effectively limits the rotation of the drilling tool 400 during operation, ensuring that the drill bit 410 always maintains the correct drilling direction, avoiding deviation of the drilling position caused by the rotation of the drilling tool 400, and improving the drilling accuracy.

[0050] It should be further pointed out that the end of the sliding rod 700 abutting against the drilling tool 400 can be welded. The sliding rod 700 can also be fixed by bolts, so that the sliding rod 700 can be fixed on the lifting frame 300, and the end of the sliding rod 700 abutting against the drilling tool 400 does not need to be fixedly connected with the drilling tool 400, which is more conducive to the replacement of the drilling tool 400.

[0051] Further, at least two limiting blocks 800 are provided on the support 100, and the two limiting blocks 800 are used to abut against the bicycle frame on the support frame 200. After the bicycle frame abuts against the limiting blocks 800, the drilling positions of the bicycle frame are located below the drill bit 410.

[0052] In this embodiment, the limiting blocks 800 abut against the bicycle frame on the support frame 200, which can quickly and accurately fix the bicycle frame at a specific position, ensure the accurate alignment of the drilling position and the drill bit 410, and greatly improve the accuracy and consistency of the drilling.

[0053] According to the principle of determining a straight line by two points, the straightness of the drilling is ensured from the direction of the bicycle frame. Moreover, the position of the bicycle frame does not need to be adjusted repeatedly by the limiting blocks 800, which saves the positioning time and thus improves the efficiency of the entire drilling operation.

[0054] Further, the drilling tool 400 is pneumatic.

[0055] In this embodiment, the pneumatic drilling tool 400 can provide a fast power response, realize high-speed drilling, and significantly improve the working efficiency of the drilling. Moreover, compared with the electric drilling tool 400, the pneumatic drilling tool 400 does not produce electromagnetic interference and is relatively cleaner and has no pollution emission during operation.

[0056] Further, the support frame 200 includes at least two support rollers 210, and the support rollers 210 have a spacing therebetween.

[0057] In this embodiment, the plurality of support rollers 210 jointly act to provide more stable support for the bicycle frame, reducing the shaking and deformation of the frame during drilling.

[0058] The interval between the supporting rollers 210 is more in line with human mechanics, and facilitates the operator to pick up or put down the bicycle frame from the bottom of the bicycle frame with one hand.
