[0001] The utility model relates to the technical field of axle manufacturing, in particular to a bicycle axle drilling machine. Background Art

[0002] A bicycle axle drilling machine is a special device used to process bicycle axles. In bicycle production, the axle is an important component connecting the wheels and is usually made of steel. The main function of the axle drilling machine is to drill holes or process eyes in the center of the axle to install bearings or connect other components. During the processing, the axle is fixed on the machine tool, and the tool on the spindle cuts or drills along the preset trajectory to form the required hole diameter and shape.

[0003] If the fixing device of the existing bicycle axle drilling machine cannot adapt to axles of different sizes and lengths, or if the fixing device is not designed with a fixed or adjustable range, shorter or longer axles may not be firmly fixed to the drilling machine, which may cause the axle to move or shake slightly during the drilling process, affecting the accuracy and precision of the drilling. If the fixing device cannot adapt to axles of different lengths, the operator may not be able to effectively align the center of the axle with the working area of ​​the drilling machine when clamping the axle, which will result in inaccurate drilling position and may even cause the axle to deviate from the desired drilling position. Utility Model Content

[0004] The utility model adopts the design of adjustable fixing device and superimposed plate, so that the drilling machine can adapt to bicycle axles of different sizes and lengths. In this way, both shorter and longer axles can be firmly fixed on the drilling machine to ensure that they will not move or shake during the processing.

[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a bicycle axle drilling machine, comprising a drilling machine body, a drill bit being installed on the drilling machine body, a fixing device being provided on the outer wall of the drilling machine body, a bicycle axle being placed in the fixing device, a clamping member being provided on the outer wall of the fixing device, and a limit member being further provided on the clamping member;

[0006] The clamping members are symmetrically arranged in two groups on the left and right outer walls of the fixing device. The clamping members rotate on the side walls of the fixing device to clamp the bicycle axle, and the limiting member limits the rotation of the clamping members by rotating.

[0007] Preferably, the clamping member includes a mounting plate installed on the side wall of the fixing device, a rotating shaft rotatably connected to the mounting plate, a first screw rod connected to the outer wall of the rotating shaft, a clamping plate sleeved on the outer wall of the first screw rod, a first threaded sleeve threadedly connected to the outer wall of the first screw rod, and a superimposed plate arranged on the outer wall of the top end of the fixing device.

[0008] Preferably, the mounting plates are symmetrically arranged in two groups, the two groups of mounting plates are rotatably connected with rotating shafts, and the limiting member is arranged on the shaft body at the outer end of the rotating shaft.

[0009] Preferably, the clamping plate is shaped as a rectangle, and a rubber pad is provided on the outer wall of the bottom end of the clamping plate.

[0010] Preferably, the first threaded sleeve is threadedly connected to the outer wall of the first screw rod above the superimposed plate, and the first threaded sleeve drives the clamping plate to move on the first screw rod.

[0011] Preferably, the limiting member includes a second screw rod extendingly connected to one end of the rotating shaft, a baffle mounted on the end of the second screw rod, and a second threaded sleeve threadedly connected to the outer wall of the second screw rod.

[0012] Preferably, a rubber pad is provided on the contact end surface between the inner end of the second threaded sleeve and the outer wall of the mounting plate.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. Enhanced adaptability: Through the design of adjustable fixing devices and overlapping plates, the drilling machine can adapt to bicycle axles of different sizes and lengths. In this way, both shorter and longer axles can be firmly fixed on the drilling machine to ensure that they will not move or shake during the processing.

[0015] 2. Improved drilling accuracy: The clamp securely holds the axle and the rectangular design of the clamping plate provides a stable surface, significantly improving the accuracy and precision of the drilling operation. The stable clamp ensures that the center of the axle is accurately aligned with the drilling machine's working area.

[0016] 3. Avoid position deviation: Since the device can adapt to axles of different lengths, it is easier for the operator to align the center of the axle with the working area of ​​the drill when clamping the axle, reducing the drilling position deviation caused by inaccurate axle placement.

[0017] 4. Enhanced stability: The symmetrically arranged mounting plates ensure the balance of the entire device, avoiding deviation during clamping and drilling. The rotating connection of the shaft allows the clamp to rotate on the axis, which can easily adjust and fix bicycle axles of different lengths, further enhancing the stability of the entire system.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] See also Figures 1-4 The utility model provides a technical solution: a bicycle axle drilling machine, comprising a drilling machine body 1, a drill bit 2 is installed on the drilling machine body 1, a fixing device 3 is provided on the outer wall of the drilling machine body 1, a bicycle axle 4 is placed in the fixing device 3, a clamping member 5 is provided on the outer wall of the fixing device 3, and a limit member 6 is also provided on the clamping member 5;

[0026] Two groups of clamping members 5 are symmetrically arranged on the left and right outer walls of the fixing device 3. The clamping members 5 rotate on the side walls of the fixing device 3 to clamp the bicycle axle 4. The limiting member 6 limits the rotation of the clamping member 5 by rotating.

[0027] The clamping member 5 includes a mounting plate 51 installed on the side wall of the fixing device 3, a rotating shaft 52 rotatably connected to the mounting plate 51, a first screw rod 53 connected to the outer wall of the rotating shaft 52, a clamping plate 54 sleeved on the outer wall of the first screw rod 53, a first threaded sleeve 55 threadedly connected to the outer wall of the first screw rod 53, and a superimposed plate 56 arranged on the outer wall of the top end of the fixing device 3.

[0028] The limiting member 6 is provided on the outer end of the shaft 52 and includes a second screw rod 61 extending and connected to one end of the shaft 52, a baffle 62 mounted on the end of the second screw rod 61, and a second threaded sleeve 63 threadedly connected to the outer wall of the second screw rod 61.

[0029] When clamping and fixing bicycle axles 4 of different lengths, the staff only needs to stack the stacking plate 56 on the top of the fixing device 3 according to the length of the bicycle axle 4, so that the bicycle axle 4 remains stable in the stacked fixing device 3, and then rotate the first screw rod 53, so that the first screw rod 53 drives the rotating shaft 52 to rotate on the mounting plate 51 until the first screw rod 53 rotates and fits the outer wall of the stacking plate 56, and then screw the first threaded sleeve 55 downward, so that the first threaded sleeve 55 drives the clamping plate 54 to move downward until the bottom end of the clamping plate 54 contacts the outer wall of the top stacking plate 56, and the two sets of clamping plates 54 clamp and fix it.

[0030] It is worth noting that the mounting plates 51 are symmetrically arranged in two groups. The symmetrical arrangement of the two mounting plates 51 can ensure the balance of the entire device, avoid deviation during the clamping and drilling process, and improve stability. The two groups of mounting plates 51 are rotatably connected to the rotating shaft 52. The rotating shaft 52 is rotatably connected to the mounting plates 51, allowing the clamp to rotate on the shaft, which can facilitate the adjustment and fixing of bicycle axles 4 of different lengths.

[0031] The clamping plate 54 is rectangular in shape. The rectangular shape of the clamping plate 54 may be to better fit and fix the axle and provide a stable support surface. The outer wall of the bottom end of the clamping plate 54 is provided with a rubber pad. The rubber pad at the bottom end can increase the friction with the workpiece to prevent slipping during drilling, and also protect the axle surface from damage.

[0032] The first threaded sleeve 55 is threadedly connected to the outer wall of the first screw rod 53 above the superposition plate 56. The first threaded sleeve 55 drives the clamping plate 54 to move on the first screw rod 53. This design allows the position of the clamping plate 54 to be adjusted by rotating the first threaded sleeve 55, thereby precisely controlling the clamping force and position of the bicycle axle 4, ensuring processing accuracy.

[0033] After the first screw rod 53 is rotated, the second threaded sleeve 63 can be rotated inwardly to screw the second threaded sleeve 63 inwardly on the second screw rod 61. This causes the inner end of the second threaded sleeve 63 to be clamped and limited by the outer wall of the mounting plate 51. The first screw rod 53 cannot be easily rotated by the rotating shaft 52. At this time, the bicycle axle 4 is firmly fixed in the fixing device 3 and the superimposed plate 56, and the drilling operation can be carried out.

[0034] It is worth noting that a rubber pad is provided on the contact end surface between the inner end of the second threaded sleeve 63 and the outer wall of the mounting plate 51. The rubber pad here can play a buffering and anti-slip role, ensuring that when the second threaded sleeve 63 is tightened, the mounting plate 51 will not be subjected to unnecessary wear or damage, while also increasing the stability of the connection.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
