Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of bicycle assembly, and more specifically, the present utility model relates to a pressing device for pressing a headset assembly into a bicycle front tube. Background Art

[0002] During the production and manufacturing process of bicycles, installing the headset assembly of the bicycle is a crucial step in the entire bicycle assembly process. Existing bicycle manufacturing enterprises have begun to use professional pressing devices to simultaneously press the upper headset and the lower headset of the headset assembly into the front tube of the bicycle (the front tube is the tube body of the bicycle frame used to install the front fork and the handlebar of the bicycle), ensuring that the upper headset and the lower headset can be evenly and smoothly pressed into the head tube.

[0003] On the other hand, the bicycle nameplate, as an important identifier of the bicycle product, is not only an important part of the product identifier but also directly related to the appearance quality and brand image of the product. Since only the operation of pressing the nameplate pre-pasted on the front tube is carried out, its steps are simple and repetitive compared with other installation processes. Although designing a dedicated automatic pressing device for the nameplate can improve the accuracy of nameplate pasting to a certain extent, the nameplate does not require a high-precision pasting position. Therefore, compared with the manual method, the dedicated automatic pressing device for the nameplate cannot effectively improve the efficiency of bicycle assembly. Therefore, existing bicycle manufacturing enterprises still choose to use the manual method to paste the nameplate. Summary of the Utility Model

[0004] In order to solve one or more of the above-mentioned technical problems, the present utility model provides a pressing device for pressing a headset assembly into a bicycle front tube, which can reduce the production and manufacturing cost of bicycles and improve the efficiency of bicycle assembly.

[0005] An embodiment of the present utility model provides a pressing device for pressing a headset assembly into a bicycle front tube, which includes:

[0006] A frame;

[0007] A positioning assembly, which is arranged on the frame and is used to fix the front tube of the bicycle;

[0008] A pressing assembly, which is arranged on the frame; and

[0009] A pressing component, which is arranged on the frame, and the pressing component includes a fixing plate connected to the frame, a first driving member arranged on the fixing plate, and a buffer cushion block connected to the first driving member;

[0010] Among them, the headset assembly includes an upper headset pre-installed on the top of the front tube and a lower headset pre-installed on the positioning assembly. The pressing-in assembly can press the pre-installed upper headset and the lower headset into the front tube. During the process of pressing in the upper headset and the lower headset, the first driving member drives the buffer pad to press against the sign pre-stuck on the tube wall of the front tube to stick the sign tightly.

[0011] Since the upper headset and the lower headset are usually pressed into the top and bottom of the front tube, the positioning assembly and the pressing-in assembly in the traditional pressing-in device for the headset assembly are usually arranged in the vertical direction to simultaneously press the upper headset pre-installed on the front tube and the lower headset pre-loaded on the positioning assembly into the front tube. The pressing-in device provided in this embodiment innovatively adds a pressing component moving in the horizontal direction to the traditional pressing-in device for the headset assembly, enabling the pressing-in device to stick the sign pre-stuck on the tube wall of the front tube tightly while pressing the pre-installed upper headset and lower headset into the front tube. Thus, the sticking of the sign is taken into account during the installation of the headset assembly, and two installation steps are completed at the same time, saving the time for the separate operation of sticking the sign and improving the assembly efficiency of the bicycle. And it replaces the manual sticking method, effectively reducing the production cost. Moreover, since the movement directions of the pressing component, the positioning assembly, and the pressing-in assembly do not interfere with each other, the added pressing component will not affect the original positioning assembly and pressing-in assembly, facilitating the modification and upgrade of the traditional pressing-in device for the headset assembly by the operator.

[0012] Further, an arc-shaped groove with a groove wall that can fit the tube wall of the front tube is provided on the buffer pad.

[0013] Further, the cross-sectional shape of the arc-shaped groove in the vertical direction is semi-circular.

[0015] Further, a kidney-shaped hole is provided on the frame in the vertical direction. The pressing component further includes a bolt that can sequentially pass through the kidney-shaped hole and the fixing plate and be threadedly connected to a nut.

[0016] Further, the positioning assembly includes:

[0017] A support rod, which is arranged on the frame;

[0018] A first positioning member, which is arranged at the top of the support rod, and a first positioning protrusion for positioning the lower headset is provided on the first positioning member.

[0019] Further, the support rod passes through the frame and is threadedly connected to the frame to adjust the first positioning member to be closer to or farther from the pressing assembly.

[0020] Further, the pressing assembly includes:

[0021] A second driving member disposed on the frame;

[0022] A second positioning member disposed on the second driving member and capable of pressing against the upper bowl set and pressing it into the front tube.

[0023] Further, the first driving member includes a pneumatic cylinder, an electric cylinder or a hydraulic cylinder; and / or

[0024] The second driving member includes a pneumatic cylinder, an electric cylinder or a hydraulic cylinder.

[0025] Further, during the process of pressing one upper bowl set and one lower bowl set into the front tube, the first driving member drives the buffer pad to press against the nameplate multiple times. Description of the Drawings

[0040] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present disclosure.

[0041] Figure 1 The structural schematic diagrams of a pressing-in device for pressing the headset assembly 100 into the bicycle front tube 200, the front tube 200, and the headset assembly 100 provided in this embodiment are shown. Figure 2 The structural schematic diagrams of the front tube 200 and the headset assembly 100 provided in this embodiment are shown. Figure 3 The structural schematic diagram of the pressing-in device provided in this embodiment is shown. As Figures 1 - 3 shown, this embodiment provides a pressing-in device for pressing the headset assembly 100 into the bicycle front tube 200, which includes a frame 1, a positioning assembly 2, a pressing-in assembly 3, and a pressing component 4. The positioning assembly 2 is arranged on the frame 1 and is used to fix the front tube 200 of the bicycle. The pressing-in assembly 3 is arranged on the frame 1. The pressing component 4 is arranged on the frame 1. The pressing component 4 includes a fixed plate 41 connected to the frame 1, a first driving member 42 arranged on the fixed plate 41, and a buffer cushion block 43 connected to the first driving member 42. Among them, the headset assembly 100 includes an upper headset 101 pre-installed on the top of the front tube 200 and a lower headset 102 pre-installed on the positioning assembly 2. The pressing-in assembly 3 can press the pre-installed upper headset 101 and lower headset 102 into the front tube 200. During the process of pressing the upper headset 101 and lower headset 102, the first driving member 42 drives the buffer cushion block 43 to press against the label pre-stuck on the tube wall of the front tube 200 to stick the label tightly.

[0042] Since the upper headset assembly 101 and the lower headset assembly 102 are usually pressed into the top and bottom of the front tube 200, the positioning assembly 2 and the pressing assembly 3 in the pressing device of the traditional headset assembly 100 are usually arranged in the vertical direction to simultaneously press the upper headset assembly 101 pre-mounted on the front tube 200 and the lower headset assembly 102 pre-loaded on the positioning assembly 2 into the front tube 200. The pressing device provided in this embodiment innovatively adds a pressing component 4 that moves in the horizontal direction to the pressing device of the traditional headset assembly 100 (if the movement direction of pressing the upper headset assembly 101 and the lower headset assembly 102 onto the front tube 200 is the vertical direction, the movement direction of sticking the nameplate tightly to the tube wall is the horizontal direction), so that the pressing device can stick the nameplate pre-stuck on the tube wall of the front tube 200 tightly while pressing the pre-assembled upper headset assembly 101 and lower headset assembly 102 into the front tube 200. Thus, when installing the headset assembly 100, the tight sticking of the nameplate is taken into account, and two installation steps are completed at the same time, saving the time for the operation of sticking the nameplate separately and improving the assembly efficiency of the bicycle. And it replaces the manual sticking method, effectively reducing the production cost. Moreover, since the movement directions of the pressing component 4, the positioning assembly 2, and the pressing assembly 3 do not interfere with each other, the added pressing component 4 will not affect the original positioning assembly 2 and pressing assembly 3, so that it is convenient for the operator to transform and upgrade the pressing device for the traditional headset assembly 100.

[0043] Specifically, the installation process of the headset assembly 100 is as follows: First, place the lower headset assembly 102 of the headset assembly 100 on the positioning assembly 2 to position the lower headset assembly 102. Then, align the front tube 200 with the upper headset assembly 101 pre-mounted on the top with the lower headset assembly 102. Subsequently, start the pressing device, and while the pressing assembly 3 presses the upper headset assembly 101 into the top of the front tube 200, it also presses the lower headset assembly 102 into the bottom of the front tube 200. In addition, during the pressing process, the first driving member 42 of the pressing component 4 drives the buffer cushion block 43 to press the nameplate pre-stuck on the tube wall to stick the nameplate tightly.

[0044] Figure 4 The structural schematic diagram of the buffer cushion block 43 provided in this embodiment is shown. As Figure 4 and in combination with Figures 1 - 3 shown, preferably, the buffer cushion block 43 is provided with an arc-shaped groove 431 whose groove wall can fit the tube wall of the front tube 200. Compared with the case where no arc-shaped groove 431 or other shaped grooves are provided, the arc-shaped groove 431 can adaptively fit the nameplate on the tube wall at one time during the process of the first driving member 42 driving the buffer cushion block 43 to move once.

[0045] Preferably, the cross-sectional shape of the arc-shaped groove 431 in the vertical direction is semi-circular, so as to expand the range of the groove wall against which the arc-shaped groove 431 abuts as much as possible on the premise of ensuring that the arc-shaped groove 431 can completely adhere to the pipe wall, so that the buffer cushion block 43 can adapt to more signs of different sizes and improve the applicability of the pressing device.

[0046] Preferably, the buffer cushion block 43 is made of rubber or polyurethane material. By using the self-characteristics of the rubber material and polyurethane material, it can provide stable support and shock absorption effect when the buffer cushion block 43 adheres to the pipe wall, so as to protect the front pipe 200 and the sign stuck on the front pipe 200 from rigid impact and protect the integrity of the front pipe 200 and the sign stuck on the front pipe 200.

[0047] Furthermore, a waist-shaped hole 11 is arranged on the frame 1 in the vertical direction. The pressing component 4 further includes a bolt 5 that can sequentially pass through the waist-shaped hole 11 and the fixing plate 41 and then be threadedly connected to the nut 6. The nut 6 and the bolt 5 that are threadedly connected can disassemble the fixing plate 41. After disassembly, the fixing plate 41 can be moved in the vertical direction. Then, the bolt 5 passes through the waist-shaped hole 11 on the frame 1 and the fixing plate 41 and is threadedly connected to the nut 6 to adjust the fixing plate 41 in the vertical direction, so that the pressing component 4 can adapt to signs at different pasting positions, thereby improving the applicability of the pressing device.

[0048] Figure 5 The structural schematic diagram of the lower bowl set 102 provided in this embodiment placed on the positioning component 2 is shown. As Figure 5 And in combination with Figures 1 - 3 shown, the positioning component 2 includes a support rod 21 and a first positioning member 22. The support member is arranged on the frame 1. The first positioning member 22 is arranged at the top of the support rod 21, and a first positioning protrusion 221 for positioning the lower bowl set 102 is arranged on the first positioning member 22. When installing the bowl set assembly 100, the lower bowl set 102 is sleeved outside the first positioning protrusion 221 to position the lower bowl set 102, so as to facilitate pressing the upper bowl set 101 and the lower bowl set 102 into the front pipe 200 at one time.

[0049] In this embodiment, the support rod 21 passes through the frame 1 and is threadedly connected to the frame 1 to adjust the first positioning member 22 to be closer to or farther from the pressing assembly 3. By screwing the support rod 21, the position of the first positioning member 22 in the vertical direction can be adjusted, so that the positioning assembly 2 can adapt to front tubes 200 of different heights, thereby improving the applicability of the pressing device. In other embodiments, the support rod 21 can also be driven by a linear driving mechanism to move in the vertical direction, so as to adjust the position of the first positioning member 22 in the vertical direction. However, in the actual production process, the position of the first positioning member 22 in the vertical direction is not often adjusted. Therefore, the manual method of threaded connection provided in this embodiment is selected for adjustment to save the cost of manufacturing the pressing device. This embodiment does not specifically limit the method of adjusting the first positioning member 22 in the vertical direction. Any structure that can realize the adjustment of the first positioning member 22 in the vertical direction is within the scope of the embodiments of the present disclosure.

[0050] In this embodiment, since the lower bowl set 102 is a pipe fitting provided with a circular opening, the first positioning protrusion 221 is correspondingly set as a circular protrusion. And since the lower bowl set 102 also needs to be placed in advance, the first positioning protrusion 221 is set as a stepped circular protrusion to cooperate with the pressing assembly 3 to press the lower bowl set 102 into the bottom of the front tube 200.

[0051] Continue to refer to Figures 1 - 3 As shown, the pressing assembly 3 includes a second driving member 31 and a second positioning member 32. The second driving member 31 is arranged on the frame 1. The second positioning member 32 is arranged on the second driving member 31 and can press against the upper bowl set 101 and press it into the front tube 200. During the process of pressing the upper bowl set 101, the positioning protrusion of the second positioning member 32 can pass through the upper bowl set 101, so as to realize the positioning of the upper bowl set 101.

[0052] In this embodiment, the first driving member 42 includes a cylinder, an electric cylinder or a hydraulic cylinder. The second driving member 31 includes a cylinder, an electric cylinder or a hydraulic cylinder. In other embodiments, the first driving member 42 and the second driving member 31 can also be a lead screw nut 6 mechanism or a synchronous belt assembly and other linear output driving mechanisms. This embodiment does not limit the specific structures of the first driving member 42 and the second driving member 31. Any driving mechanism that can realize linear output is within the protection scope of the embodiments of the present disclosure.

[0053] Preferably, during the process of pressing one upper bowl set 101 and one lower bowl set 102 into the front tube 200, the first driving member 42 drives the buffer cushion block 43 to press against the nameplate multiple times, so that the nameplate can be pasted more firmly on the pipe wall.

[0054] In this embodiment, during the process of pressing an upper bowl set 101 and a lower bowl set 102 into the front tube 200, the first driving member 42 drives the buffer cushion block 43 to press against the nameplate twice, so as to make more full use of the action time for pressing the upper bowl set 101 and the lower bowl set 102, so that the pressing device can paste the nameplate more firmly on the pipe wall without increasing the action time.
