Description

Technical Field

[0001] This invention relates to the field of bicycle handlebar stem pressing equipment, and more particularly to a bicycle handlebar stem pressing equipment and its pressing method. Background Technology

[0002] A bicycle handlebar stem inserter is a tool used to accurately install the handlebar stem of a bicycle into the frame. This tool is commonly used in the assembly and repair of bicycles.

[0003] The invention disclosed in CN115673756A is a continuous pressing device. Its key technical features include a resolver nut pressing device, a C-ring pressing device, a conveyor line, and a robot. In this continuous pressing device, a first conveying mechanism enables the loading of intermediate rotor parts, and the first loading mechanism simultaneously enables the translation and flipping of resolver nuts. Furthermore, the first pressing mechanism enables the continuous assembly of resolver nuts. Further, a second conveying mechanism enables the loading of intermediate rotor parts assembled with resolver nuts, and the second loading mechanism simultaneously enables the translation and unloading of C-rings. The second pressing mechanism then enables the continuous assembly of C-rings, thereby achieving axial locking of the resolver in the intermediate rotor parts.

[0004] Regarding the aforementioned issues, the following technical defects exist: Bicycle handlebar stem pressing equipment is used to accurately install bicycle handlebar stems onto the frame connecting tubes. Typically, during use, the frame connecting tube is first fixed to the inner wall of the support base, and the stem is placed inside the pressing equipment. The pressing equipment can then be started to complete a single pressing operation. However, it has been found that when multiple different types of stems need to be pressed continuously, traditional equipment suffers from a fixed workstation and time-consuming adjustments. This slows down the equipment's processing efficiency and severely impacts the overall efficiency and continuity of the pressing operation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a bicycle handlebar stem pressing device and pressing method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a presser and an adjusting mechanism. Two stamping devices are installed on the side wall of the presser, and four support seats are installed on the bottom wall of the presser. An adjusting mechanism is provided on one side of the presser, and the adjusting mechanism includes two support arms. Both support arms are fixedly connected to one side of the presser. A fixed plate is fixedly connected to one side of the two support arms. A connecting plate is fixedly connected to the side of the fixed plate near the support arm. A motor is fixedly connected to one side of the connecting plate. A turntable is fixedly connected to the output end of the motor. A first electric push rod is fixedly connected to the side of the connecting plate near the motor. An adjuster is rotatably connected to the output end of the first electric push rod. An adjusting groove is provided on the fixed plate corresponding to the position of the adjuster. A connecting rod is fixedly passed through the inner wall of the adjusting groove. The arc surface of the connecting rod is rotatably connected to the inner wall of the adjuster. A connecting plate is fixedly connected to the side of the turntable away from the motor. Cylinders are fixedly connected to both sides of the connecting plate. An adjusting plate is fixedly connected to the output end of the cylinder. The four support seats are respectively fixedly connected to two adjusting plates.

[0007] The above technical solution achieves the bicycle handlebar stem pressing device, which is used to accurately install bicycle handlebar stems onto the frame connecting tube. Normally, in use, the frame connecting tube is first fixed to the inner wall of the support base, and the stem is placed in the inner wall of the pressing equipment. The pressing equipment can then be started to complete a single pressing operation. However, it was found that when multiple different types of stems need to be pressed continuously, traditional equipment suffers from a fixed, single workstation and time-consuming adjustments, leading to slower processing efficiency and severely impacting the overall efficiency and continuity of the pressing operation. This problem can be solved by an adjustment mechanism. The adjustment mechanism provides the support base with two quickly switchable workstations. While pressing is being performed at one workstation, the operator can prepare for clamping the next workpiece at the other workstation, achieving parallel operation of the pressing and clamping processes. This significantly reduces equipment waiting time, thereby significantly improving the overall utilization rate and production efficiency of the equipment, making batch pressing operations smoother and more efficient.

[0008] Preferably, an adjusting block is fixedly connected to the output end of the cylinder, and an auxiliary groove is provided on the turntable corresponding to the position of the adjusting block. The adjusting block is slidably connected to the inner wall of the auxiliary groove, and a connecting block is slidably connected to one side of the adjusting block. The connecting block is fixedly connected to the bottom wall of the presser.

[0009] By adopting this preferred solution, the adjusting block and the auxiliary groove are slidably connected to each other, providing a stable guide for the cylinder drive, ensuring the linearity and smoothness of the movement of the adjusting plate and support during the adjustment process, and avoiding skewing or jamming.

[0010] Preferably, two guide blocks are fixedly connected to one side of the connecting block, and the two guide blocks are slidably connected to the two sides of the adjusting block respectively.

[0011] By adopting the above technical solution, the sliding cooperation between the guide block and the adjusting block on both sides is achieved, forming a double guiding constraint, which further enhances the stability of the adjusting motion and effectively improves the positioning accuracy and reliability of the adjusting mechanism in the process of repeated adjustment.

[0012] Preferably, a connecting groove is provided on the side of the turntable away from the connecting plate, and a guide rod is slidably connected to the inner wall of the connecting groove. One end of the arc surface of the guide rod is fixedly connected to one side of the fixing plate.

[0013] By adopting the above technical solution, a sliding fit between the guide rod and the connecting groove is achieved, providing additional radial support and guidance for the rotation of the turntable, and greatly enhancing the rigidity and operational stability of the turntable when subjected to lateral forces.

[0014] Preferably, a contact block is fixedly connected to one end of the arc surface of the guide rod near the arc surface of the connecting groove, and the cross-section of the contact block is circular.

[0015] By adopting the above technical solution, the contact block with a circular cross-section transforms sliding friction into rolling friction, which significantly reduces the wear between the guide rod and the connecting groove, improves the smoothness of movement, and extends the service life of the guide rod.

[0016] Preferably, a contact pad is fixedly connected to the side of the regulator near the turntable, and the side of the contact pad away from the regulator has anti-slip texture.

[0017] By adopting the above technical solution, the contact pad with anti-slip texture increases the friction coefficient between the regulator and the turntable, ensuring the stability of the regulator in fixing the turntable.

[0018] Preferably, an auxiliary mechanism is provided on one side of the adjusting plate. The auxiliary mechanism includes a support plate, which is fixedly connected to one side of the adjusting plate. A second electric push rod is fixedly connected to one side of the support plate. A connecting block is fixedly connected to the output end of the second electric push rod. A push block is fixedly connected to the side of the connecting block away from the second electric push rod. An abutment block is slidably connected to one side of the push block. A sliding rod slides through the inner wall of the abutment block. One end of the arc surface of the sliding rod is fixedly connected to one side of the adjusting plate. A spring is sleeved on the other end of the arc surface of the sliding rod. The two ends of the spring are fixedly connected to the sliding rod and the abutment block, respectively. A top block is fixedly connected to the abutment block at the position corresponding to the two support seats. An ejection groove is opened on the support seat at the position corresponding to the top block. The top block is slidably connected to the inner wall of the ejection groove.

[0019] The above technical solution addresses the issue that after the riser is pressed in and the workstation is switched, when the equipment enters the workpiece unloading and preparation stage, the operator needs to manually remove the pressed workpiece from the support base, and then clean or adjust the support base for the next use. However, this process is inefficient and carries the risk of workpiece jamming, leading to extended workstation preparation time, affecting the smoothness of workstation switching, and ultimately slowing down the overall production cycle. This problem can be solved by an auxiliary mechanism. This mechanism avoids the impact of slow manual unloading on workstation switching speed and production cycle, significantly shortening the workpiece replacement and preparation time for a single workstation. This allows the workstation to quickly enter a ready state during the pressing cycle interval, improving the effectiveness of the support base.

[0020] Preferably, an auxiliary block is fixedly connected to the side of the top block away from the abutment block, and the cross-section of the auxiliary block is rectangular.

[0021] By adopting the above technical solution, the rectangular cross-section of the auxiliary block increases the contact stability between the end of the top block and the frame connecting tube, thus avoiding damage caused by direct contact between the two.

[0022] Preferably, the top block is a steel block.

[0023] By adopting the above technical solution, a steel top block is achieved, which has excellent strength, rigidity and wear resistance, can withstand frequent ejection operation cycles, and has high reliability and durability.

[0024] S1. Place the bicycle frame connecting tube and handlebar stem on the support base, ensuring accurate positioning. After inspecting the equipment and materials and confirming everything is correct, perform the preparatory work before pressing in to facilitate subsequent operations.

[0025] S2. Start the presser and slowly push the handlebar stem down into the frame connecting tube. During this process, the stamping equipment will operate to fix the handlebar stem, ensuring a tight fit and safety between it and the frame connecting tube.

[0026] S3. After pressing in, carefully check the installation stability of the handlebar stem and verify that the connection is secure. If any problems are found, make adjustments and corrections to ensure that the final product meets quality standards and ensures safe driving.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting an adjustment mechanism, the pressing work can be completed through the adjustment mechanism. The adjustment mechanism enables the support base to have two working positions that can be quickly switched, thereby realizing the parallel execution of pressing operations and clamping preparation, significantly reducing equipment waiting time, improving overall utilization and production efficiency, and making batch pressing operations smoother and more efficient.

[0028] 2. In this invention, by setting an auxiliary mechanism, when the workpiece is taken out from the support base, the workpiece can be quickly unloaded through the auxiliary mechanism, thereby greatly shortening the change and preparation time of a single station and ensuring that the station is ready quickly in the pressing cycle gap. This not only reduces the dependence on manual operation and labor intensity, but also ensures the smoothness of continuous operation of multiple stations through coordination with the rotation adjustment mechanism, further enhancing the overall high-efficiency operation advantage of the equipment.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, as Figure 1-9 As shown, the present invention provides a bicycle handlebar stem pressing device and pressing method, including a presser 1 and an adjustment mechanism 2. Two stamping devices 4 are installed on the side wall of the presser 1, and four support seats 5 are installed on the bottom wall of the presser 1. An adjustment mechanism 2 is provided on one side of the presser 1, and an auxiliary mechanism 3 is provided on one side of the adjustment plate 212.

[0034] The specific settings and functions of its adjustment mechanism 2 and auxiliary mechanism 3 will be explained in detail below.

[0035] like Figure 2 - Figure 6As shown, the adjustment mechanism 2 includes two support arms 201, both of which are fixedly connected to one side of the presser 1. A fixing plate 202 is fixedly connected to one side of each support arm 201. A connecting plate 203 is fixedly connected to the side of the fixing plate 202 near the support arm 201. A motor 204 is fixedly connected to one side of the connecting plate 203. A turntable 209 is fixedly connected to the output end of the motor 204. A first electric push rod 205 is fixedly connected to the side of the connecting plate 203 near the motor 204. An adjuster 206 is rotatably connected to the output end of the first electric push rod 205. An adjustment groove 207 is provided on the fixing plate 202 corresponding to the position of the adjuster 206. A connecting rod 208 is fixedly passed through the inner wall of the adjustment groove 207. The arc surface of the connecting rod 208 is parallel to the inner wall of the adjusting groove 207. The inner wall of the regulator 206 is rotatably connected, and a connecting plate 210 is fixedly connected to the side of the turntable 209 away from the motor 204. Cylinders 211 are fixedly connected to both sides of the connecting plate 210, and an adjusting plate 212 is fixedly connected to the output end of the cylinders 211. Four support seats 5 are fixedly connected to two adjusting plates 212 respectively. The bicycle handlebar stem pressing device is used to accurately install the bicycle handlebar stem into the frame connecting tube. Normally, in use, the frame connecting tube is first fixed in the inner wall of the support seat 5, and the stem is placed in the inner wall of the stamping device 4. Then, the stamping device 4 can be started to complete a single pressing. However, in this process, it was found that when multiple different types of stems need to be pressed continuously, traditional equipment suffers from a single fixed workstation and adjustment... The issue of time consumption slows down the processing efficiency of the equipment, seriously affecting the overall efficiency and continuity of the pressing operation. This problem can be solved by adjusting mechanism 2. Adjusting mechanism 2 enables the support base 5 to have two quickly switchable working positions. While pressing is being performed at one position, the operator can prepare for clamping the next workpiece at the other position, realizing parallel operation of pressing and clamping processes, greatly reducing equipment waiting time, and thus significantly improving the overall utilization rate and production efficiency of the equipment, making batch pressing operations smoother and more efficient. The output end of cylinder 211 is fixedly connected to adjusting block 213, and the turntable 209 has an auxiliary groove 216 corresponding to the position of adjusting block 213. The inner wall is slidably connected, and a connecting block 214 is slidably connected to one side of the adjusting block 213. The connecting block 214 is fixedly connected to the bottom wall of the presser 1. The adjusting block 213 and the auxiliary groove 216 are slidably connected to each other, providing a stable guide for the cylinder 211 to drive, ensuring the linearity and smoothness of the movement of the adjusting plate 212 and the support seat 5 during the adjustment process, and avoiding skewness or jamming. Two guide blocks 215 are fixedly connected to one side of the connecting block 214. The two guide blocks 215 are slidably connected to the two sides of the adjusting block 213 respectively. The sliding cooperation between the guide blocks 215 and the two sides of the adjusting block 213 forms a double guiding constraint, which further enhances the stability of the adjustment movement and effectively improves the positioning accuracy and reliability of the adjusting mechanism 2 in the repeated adjustment process.A connecting groove 217 is provided on the side of the turntable 209 away from the connecting plate 210. A guide rod 218 is slidably connected to the inner wall of the connecting groove 217. One end of the arc surface of the guide rod 218 is fixedly connected to one side of the fixed plate 202. The sliding fit between the guide rod 218 and the connecting groove 217 provides additional radial support and guidance for the rotational movement of the turntable 209, greatly enhancing the rigidity and operational stability of the turntable 209 when subjected to lateral forces. A contact block 219 is fixedly connected to the end of the arc surface of the guide rod 218 near the arc surface of the connecting groove 217. The cross-section of the contact block 219... The circular contact block 219 converts sliding friction into rolling friction, significantly reducing wear between the guide rod 218 and the connecting groove 217, improving the smoothness of movement, and extending the service life of the guide rod 218. A contact pad 220 is fixedly connected to the side of the adjuster 206 closest to the turntable 209. The side of the contact pad 220 away from the adjuster 206 has anti-slip textures. The anti-slip textures on the contact pad 220 increase the coefficient of friction between the adjuster 206 and the turntable 209, ensuring the stability of the adjuster 206 in fixing the turntable 209.

[0036] like Figure 7 - Figure 9As shown, the auxiliary mechanism 3 includes a support plate 301, which is fixedly connected to one side of the adjusting plate 212. A second electric actuator 302 is fixedly connected to one side of the support plate 301. A connecting block 303 is fixedly connected to the output end of the second electric actuator 302. A push block 304 is fixedly connected to the side of the connecting block 303 away from the second electric actuator 302. An abutment block 305 is slidably connected to one side of the push block 304. A sliding rod 306 slides through the inner wall of the abutment block 305. One end of the arc surface of the sliding rod 306 is connected to the adjusting plate 212. 2. A fixed connection is made on one side. A spring 307 is fitted on the other end of the arc surface of the sliding rod 306. The two ends of the spring 307 are fixedly connected to the sliding rod 306 and the abutment block 305 respectively. A top block 309 is fixedly connected to the abutment block 305 at the position corresponding to the two support seats 5. An ejection groove 308 is opened on the support seat 5 at the position corresponding to the top block 309. The top block 309 is slidably connected to the inner wall of the ejection groove 308. After the riser is pressed in and the workstation is switched, when the equipment enters the workpiece unloading and preparation stage, the operator needs to manually unload the pressed workpiece. The part is removed from support 5, and then support 5 is cleaned or adjusted for the next use. In this process, it was found that manual unloading is inefficient and carries the risk of workpiece jamming, which leads to prolonged workstation preparation time, affects the smoothness of workstation changeover, and consequently slows down the overall production cycle. This problem can be solved by auxiliary mechanism 3. Auxiliary mechanism 3 avoids the problem of slow manual unloading affecting workstation changeover speed and production cycle, and can greatly shorten the workpiece changeover and preparation time of a single workstation, enabling the workstation to operate quickly during the pressing cycle interval. The system quickly enters the ready state, improving the performance of the support base 5. An auxiliary block 310 is fixedly connected to the side of the top block 309 away from the abutment block 305. The cross-section of the auxiliary block 310 is rectangular. The rectangular cross-section of the auxiliary block 310 increases the contact stability between the end of the top block 309 and the frame connecting tube, avoiding direct contact and damage. The top block 309 is a steel block. The steel top block 309 has excellent strength, rigidity and wear resistance, and can withstand frequent ejection operation cycles, ensuring reliability and durability.

[0037] The overall working principle is as follows: When it is necessary to rotate the support base 5 to improve the overall performance of the stamping equipment 4, the frame connecting pipe is placed into two of the support bases 5, and then the motor 204 installed on the connecting plate 203 is started. The movement of the motor 204 will drive the turntable 209 to rotate through the output end. The turntable 209 will rotate the support base 5 to the side closer to the stamping equipment 4. At this time, the first electric push rod 205 is started. The movement of the first electric push rod 205 will drive the adjuster 206 to rotate on the connecting rod 208 through the output end. At this time, the adjuster will contact one side of the turntable 209, thereby fixing the rotation angle of the turntable 209. The cylinder 211 on the connecting plate 210 is started. The movement of the cylinder 211 will drive the adjusting plate 212 to move through the output end, thereby moving the adjusting plate 212 to the lower end of the stamping equipment 4 for pressing. The operator can then place the other two frame connecting pipes into the other two support bases 5 and wait for the adjusting mechanism 2 to switch the support bases 5.

[0038] When the frame connecting tube needs to be removed from the support base 5, the second electric push rod 302 installed on the support plate 301 is activated. The movement of the second electric push rod 302 will drive the connecting block 303 and the push block 304 to move through the output end. The pushing movement will push the abutment block 305. The abutment block 305 will slide on the sliding rod 306 under force and drive the spring 307 to compress. At this time, the abutment block 305 can drive the top block 309 to be pushed out from the ejection slot 308. The frame connecting tube can be pushed out from the support base 5 through the top block 309.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
