Description

Technical Field

[0001] This utility model relates to the technical field of bicycle rim punching machines, specifically a bicycle rim punching machine that facilitates debris removal. Background Technology

[0002] Bicycle rim perforation refers to drilling holes in bicycle rims to reduce weight and improve performance. The specific operation involves drilling small holes at specific locations on the rim, typically on the tire side. By drilling these holes, the density of the material can be reduced, thus lightening the overall weight of the wheelset. This is an important improvement for cycling enthusiasts seeking lightweight designs, for example:

[0003] The announcement number CN220575300U discloses a bicycle rim drilling device for production, comprising a frame, a processing chamber rotatably connected to the upper end of the frame, a door hinged to the side wall of the processing chamber, a water tank running through the frame inside the processing chamber, a worktable fixedly mounted on the upper end of the water tank, and a two-way lead screw rotatably connected laterally inside the worktable. When drilling is required on the bicycle rim, the rim is limited and fixed by a rotating head and a two-way lead screw drive clamp, making the rim more stable during drilling. In addition, a water pump, water pipes, and spray heads can continuously spray water onto the drilling site during rim processing, which not only cools the rim but also washes away the drilling debris, preventing some of the debris from adhering to the rim and affecting subsequent assembly. Furthermore, a filter layer allows the sprayed water to be recycled, greatly saving water resources.

[0004] The existing technical solutions have the following drawbacks:

[0005] 1. Although the existing drilling device can recycle the water after spraying, the water stains on the rim after spraying need to be dried and wiped off, which is cumbersome. At the same time, it is not convenient to drill holes on the side of the tire pad to limit the rims of different diameters according to the needs.

[0006] 2. After limiting the position of the bicycle rim, it is not convenient to adjust the drilling position and direction of the rim according to the needs, and it is not convenient to improve the level of automation and work efficiency. Therefore, this utility model provides a bicycle rim punching machine that facilitates debris cleaning to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a bicycle rim punching machine that facilitates debris removal, thereby solving the problems mentioned in the background art. Although the existing punching devices can recycle the sprayed water, the subsequent drying and wiping of water stains on the rim after spraying is cumbersome. At the same time, it is not convenient to punch holes on the side of the tire pad with rims of different diameters according to the needs. After limiting the rim, it is not convenient to adjust the punching position and direction of the rim according to the needs, which hinders the improvement of automation level and work efficiency.

[0009] The upper end of the installation and processing platform is provided with a through groove in the shape of a cross. A first connecting motor is installed at the front end of the installation and processing platform. An auxiliary bearing plate is provided at the rear end of the first connecting motor. A positioning rod is rotatably connected inside the auxiliary bearing plate. A stable support plate is provided on the outer surface of the positioning rod.

[0010] An electric slide rail is installed on the upper outer side of the installation and processing platform, and an electric slider is installed inside the electric slide rail. A limiting top plate is fixed at the upper end of the electric slider, and an electric telescopic rod is provided at the upper end of the limiting top plate. A stabilizing limiting plate is provided at the lower end of the electric telescopic rod and is slidably connected to the electric slider. A processing motor is provided at the lower end of the stabilizing limiting plate, and a drilling head is installed at the lower end of the processing motor.

[0011] A protective panel is installed on the upper side of the stabilizing support plate, and a motor is installed at the front end of the protective panel. An adjusting telescopic rod connected to the installation and processing platform is installed at the front end of the motor. A connecting block is installed at the front end of the stabilizing support plate, and a positioning groove is opened inside the connecting block.

[0012] As a preferred embodiment of this utility model, the positioning rod and the stabilizing support plate are connected by a thread, and the stabilizing support plate and the auxiliary bearing plate are connected by a sliding manner.

[0013] As a preferred embodiment of this utility model, the protective panel further includes a first connecting plate disposed at the rear end of the protective panel, and a second connecting motor coaxially connected to the rear end of the first connecting plate and connected to the stable support plate. The outer surface of the first connecting plate is provided with a second connecting plate, and the outer end of the second connecting plate is equipped with a connecting positioning rod. The outer surface of the connecting positioning rod is provided with a limiting clamping plate. The outer end of the limiting clamping plate is fixedly connected with a stable positioning block, and the inside of the stable positioning block is provided with a limiting rod, and the inner end of the limiting rod is equipped with a clamping block.

[0014] As a preferred technical solution of this utility model, the first connecting plate and the second connecting plate are connected by meshing, and the second connecting plate is provided with 4 sets at equal angles on the outer end of the first connecting plate.

[0015] As a preferred technical solution of this utility model, the connecting positioning rod and the limiting clamp are connected by threads, and the limiting clamp is slidably connected to the connecting block through a columnar structure, and the longitudinal section of the connecting block is a "+" shaped structure.

[0016] As a preferred technical solution of this utility model, the longitudinal section of the stabilizing positioning block is U-shaped, and the stabilizing positioning block and the limiting rod are threadedly connected to limit the starting position of the bicycle rim.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This bicycle rim punching machine, which facilitates debris removal, solves the problems of existing punching devices, which, although able to recycle the water after spraying, require subsequent drying and wiping of water stains on the rim, making the operation cumbersome. Furthermore, it is inconvenient to punch holes on the side of the tire pads to limit the rims of different diameters as needed, and after limiting the rims, it is inconvenient to adjust the punching position and direction as needed, thus hindering the improvement of automation and work efficiency.

[0018] 1. A protective panel is installed on the upper side of the stable support plate, and a motor is installed at the front end of the protective panel. An adjusting telescopic rod connected to the installation processing platform is installed at the front end of the motor. The bicycle rim that needs to be drilled is placed on the outer surface of the stable positioning block. The electric slider slides inside the electric slide rail to automatically adjust the drilling position. Then, the electric telescopic rod is activated to move the drill head to align with the bicycle rim. The processing motor is then activated to drive the drill head to rotate, thereby performing rotary drilling. The operation is more convenient. When the installation motor is activated, it drives the protective panel to rotate, and the connecting block rotates at the upper end of the stable support plate, thereby rotating the rim to adjust the drilling position. This facilitates multi-angle drilling, improves the level of automation, and increases processing efficiency.

[0019] 2. The positioning rod is connected to the stabilizing support plate by a thread, and the stabilizing support plate is connected to the auxiliary bearing plate by a sliding method. After the bicycle rim is placed on the outer surface of the stabilizing positioning block and after being limited, the first connecting motor is started, which drives the positioning rod inside the auxiliary bearing plate to rotate, so that the stabilizing support plate slides inside the auxiliary bearing plate. At the same time, the telescopic rod is adjusted to extend and retract, driving the installation motor to move and move the clamped bicycle rim back and forth. This makes it easy to adjust the front and back position of the drilling according to the drilling direction of the drill bit. During drilling, the internal waste chips fall into the installation and processing platform through the through groove for collection. The interior can be cleaned by opening the first connecting door.

[0020] 3. The first and second connecting discs are connected by an engagement mechanism. The second connecting disc has four sets of equal angles at its outer end. The connecting positioning rod and the limiting clamp are connected by threads. The limiting clamp is slidably connected to the connecting block through a columnar structure. The longitudinal section of the connecting block is a "+" shape, and the longitudinal section of the stabilizing positioning block is a "U" shape. The threaded connection between the stabilizing positioning block and the limiting rod serves to limit the starting position of the bicycle rim. When the bicycle rim is placed on the outer end of the stabilizing positioning block, the second connecting motor is activated, causing the first connecting disc to rotate. This causes the second connecting disc to rotate as well. Simultaneously, the connecting positioning rod rotates, causing the limiting clamp to slide inside the positioning groove. This causes the stabilizing positioning block to move outward and fit against the inner diameter surface of the rim. Then, the limiting rod is rotated, and the clamping block moves to clamp both sides of the outer end of the rim, thus facilitating the limiting of rims of different diameters.
