Description

Technical Field

[0001] This invention belongs to the field of saddle manufacturing, and particularly relates to a highly stable multi-angle saddle beam straightener. Background Technology

[0002] With the improvement of people's living standards, there are more and more vehicles in cities. For convenience and health management, people are increasingly choosing electric bikes or bicycles. The number of electric bike and bicycle brands on the market is also increasing. The saddle is a crucial functional part of electric bikes and bicycles that comes into direct contact with the human body. Below the saddle is the saddle beam. However, due to accumulated tolerances of various components during production and issues with installation methods, the saddle beam is prone to problems after assembly under the saddle. This makes it difficult to guarantee that the finished saddle will 100% meet design and customer requirements, causing problems for subsequent assembly of saddle accessories, customer vehicle assembly, and product quality, and also affecting the stability and comfort of the saddle. Specific problems encountered after the saddle beam is assembled under the saddle include: 1. Inconsistent spacing or dimensions of the saddle beam's center section, varying in width from the standard; 2. Bending deformation in the straight sections of the saddle beam; 3. The saddle beam's deformation under stress causes the parallelism of the center section to fail to meet design requirements. To address these issues, existing solutions are as follows: for problems 1 and 3, manual shaping using specialized clamps is employed, which suffers from low efficiency, reliance on human experience, and numerous uncertainties; for problem 2, leveling is achieved using independent fixtures. These methods are extremely time-consuming and labor-intensive, making it difficult to achieve high precision in a short time, and are also costly. Therefore, there is an urgent need to develop a highly automated, user-friendly, and effective saddle beam straightening device. Summary of the Invention

[0003] The purpose of this invention is to provide a highly stable multi-angle saddle beam straightener that is quick and convenient to correct saddle beam deformation, adaptable to different types of saddles, has high adjustment accuracy, and does not rely on manual experience.

[0004] The technical solution adopted in this invention is as follows:

[0005] A high-stability multi-angle saddle straightener includes a support platform and a pressing head and a saddle straightening seat that are mounted on the support platform. The pressing head is positioned above the saddle straightening seat and can move up and down relative to the saddle straightening seat by being driven by a vertical pressing cylinder. The saddle straightening seat includes a front saddle support, a saddle support, and a rear saddle support arranged sequentially from front to back. The front saddle support and the rear saddle support are provided with grooves that match the front and rear structure of the saddle, so as to support the saddle when the pressing head presses down. The front saddle support and the rear saddle support are detachably mounted on the support platform.

[0006] The saddle support includes a pair of saddle straightening blocks arranged in parallel to each other. Above the saddle straightening blocks is a saddle slot that allows all or part of the straight section in the middle of the saddle to be engaged. The two saddle straightening blocks are pushed and moved by a horizontal push cylinder located on the outside of the saddle straightening blocks to achieve simultaneous inward or simultaneous outward movement.

[0007] Preferably, the movable end of the horizontal pushing cylinder is detachably connected to the saddle beam straightening block to ensure the moving accuracy of the saddle beam straightening block and facilitate the replacement of the saddle beam straightening block. More preferably, the horizontal pushing cylinder is a double-rod cylinder.

[0008] Preferably, an inward movement limiting rod is provided on each side between the two saddle beam straightening blocks; an adjustable outward movement limiting block is also provided on the outer side of each of the two saddle beam straightening blocks. Thus, when the two saddle beam straightening blocks are pushed by the horizontal pushing cylinder, they can be limited during both inward and outward movement, achieving the purpose of stroke adjustment.

[0009] More preferably, the inward displacement limiting rod is disposed on one of the saddle beam straightening blocks, and the saddle beam straightening block with the inward displacement limiting rod is provided with two threaded holes. The inward displacement limiting rod is a bolt, and the two bolts are threaded through the threaded holes and then inserted between the two saddle beam straightening blocks to achieve the purpose of inward displacement limiting.

[0010] More preferably, the outward displacement limiting block is set in a strip-shaped slot and can move left and right along the strip-shaped slot. The outward displacement limiting block is provided with a strip-shaped through slot. The outward displacement limiting block is fixed to the support platform by a fastening bolt passing through the strip-shaped through slot. When it needs to be moved, the outward displacement limiting block is first placed in the required position, and then the fastening bolt is inserted and fixed.

[0011] Preferably, the pressing head is detachably connected to the downward movable end of a vertical pressing cylinder so as to drive it to move up and down by the vertical pressing cylinder, which is mounted above the saddle beam straightening seat via a support frame.

[0012] More preferably, a guide rod is detachably connected to the side of the pressing head, and a vertical slot is provided on the support frame, the end of the guide rod can move up and down along the vertical slot.

[0013] More preferably, the vertically downward cylinder is a single-rod cylinder.

[0014] Preferably, the bottom of the pressing head is a contoured structure that matches the structure of the top of the saddle.

[0015] Preferably, the front support part of the saddle, the rear support part of the saddle, the pressing head and the two saddle beam straightening blocks are all formed by 3D printing.

[0016] Preferably, the saddle beam straightener also includes a start switch for operating the vertical pressing cylinder and the horizontal pushing cylinder. The start switch is a two-hand start switch to ensure that employees operate in a standard standing posture and prevent crushing injuries.

[0017] Preferably, the air intake and exhaust of the two horizontally pushing cylinders are controlled by a first solenoid valve, and the air intake and exhaust of the vertically pressing cylinder are controlled by a second solenoid valve. Both the first and second solenoid valves are controlled by a programmable controller to control the movement of the three cylinders, thereby achieving full automation.

[0018] More preferably, the vertically pressing cylinder is connected to a first air pipe for controlling forward movement and a second air pipe for controlling backward movement, and the two horizontally pushing cylinders are respectively connected to a third air pipe for controlling forward movement and a fourth air pipe for controlling backward movement. The third and fourth air pipes are both connected to and controlled by a first solenoid valve, and the first and second air pipes are both connected to and controlled by a second solenoid valve. Both the first and second solenoid valves are supplied with air through the main air circuit. Beneficial effects

[0019] The high-stability multi-angle saddle beam straightener of this invention, in use, places the saddle seat on the saddle beam straightening seat, with the front and rear parts of the saddle seat correspondingly placed into the saddle front support and the saddle beam rear support, respectively. The straight middle section of the saddle beam is correspondingly engaged in the saddle beam slots above the two saddle beam straightening blocks, thereby fixing the saddle seat and the saddle beam below it. Then, horizontally driven cylinders located on both sides of the two saddle beam straightening blocks are driven synchronously to adjust the horizontal spacing of the saddle beam's middle opening and the parallelism of the saddle beam as needed by pushing inward or pulling outward. At the same time, the pressing head is pressed down to press the saddle seat, correcting the bending deformation on the saddle beam, thereby completing the precise adjustment of the saddle beam. The correction system enables multi-angle correction of the saddle beam. Furthermore, the coordination of the inner and outer limit rods allows for better adjustment of the saddle beam correction block's travel distance. The entire correction process is highly efficient, precise, flexible, safe, stable, and easy to operate. The saddle front support, rear support, pressing head, and two saddle beam correction blocks can all be flexibly replaced according to the specific saddle structure, thus adapting to the correction of various saddle products. It boasts a high degree of automation, contributing to improved saddle quality, and is independent of operator experience, saving time and effort. This significantly improves subsequent saddle installation efficiency and ensures saddle stability, making it extremely practical. Attached Figure Description

[0029] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0030] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0031] like Figure 1-8 As shown, the high-stability multi-angle saddle straightener includes a support platform 1 and a pressing head 2 and a saddle straightening seat 3 that are arranged vertically on the support platform 1. The pressing head 2 is located above the saddle straightening seat 3 and can move up and down relative to the saddle straightening seat 3 by being driven by a vertical pressing cylinder 12. The saddle straightening seat 3 includes a saddle front support part 4, a saddle support part 5 and a saddle rear support part 6 arranged sequentially from front to back. The saddle front support part 4 and the saddle rear support part 6 are provided with grooves that match the front and rear structure of the saddle 7, so that the saddle 7 can be supported when the pressing head 2 presses down. The saddle front support part 4 and the saddle rear support part 6 are both detachably mounted on the support platform 1 by fixing bolts.

[0032] The saddle support 5 includes a pair of saddle straightening blocks 8 arranged in parallel to each other. Above the saddle straightening blocks 8 is a saddle slot 81 that allows all or part of the straight section in the middle of the saddle beam 71 to be inserted. The two saddle straightening blocks 8 are pushed and moved by a horizontal push cylinder 9 located on the outside of the saddle straightening blocks 8 to achieve simultaneous inward or simultaneous outward movement.

[0033] The movable end of the horizontal pushing cylinder 9 is detachably connected to the saddle beam straightening block 8 via fixing bolts to ensure the moving accuracy of the saddle beam straightening block and facilitate the replacement of the saddle beam straightening block. More preferably, the horizontal pushing cylinder 9 is a double-rod cylinder.

[0034] Between the two saddle beam straightening blocks 8, an inward movement limiting rod 10 is provided on each side. An adjustable outward movement limiting block 11 is also provided on the outer side of each of the two saddle beam straightening blocks 8. Thus, when the two saddle beam straightening blocks 8 are pushed by the horizontal pushing cylinder 9, they can be limited during both inward and outward movement, achieving the purpose of stroke adjustment.

[0035] The inner displacement limiting rod 10 is installed on one of the saddle beam straightening blocks 8, and the saddle beam straightening block 8 with the inner displacement limiting rod is provided with two threaded holes 82.

[0036] The outward displacement limiting block 11 is set in a strip-shaped slot 12 and can move left and right along the strip-shaped slot 12. The outward displacement limiting block 11 is provided with a strip-shaped through slot. The outward displacement limiting block 11 is fixed to the support platform 1 by a fastening bolt passing through the strip-shaped through slot. When it needs to be moved, first place the outward displacement limiting block in the required position, and then insert the fastening bolt to fix it.

[0037] The pressing head 2 is detachably connected to the downward movable end of a vertical pressing cylinder 12 via a threaded connection, so as to drive it to move up and down by the vertical pressing cylinder 12. The vertical pressing cylinder 12 is mounted above the saddle beam correction seat 3 via a support frame 13.

[0038] The side of the pressing head 2 is also detachably connected to a guide rod 14 by a threaded connection. The support frame 13 is provided with a vertical slot. The end of the guide rod 14 can move up and down along the vertical slot to make the stroke of the pressing head more stable when it is pressed down.

[0039] The vertical downward pressing cylinder 12 is a single-rod cylinder.

[0040] The bottom of the pressing head 2 is a contoured structure that matches the structure of the top of the saddle 7.

[0041] The front support part 4 of the saddle, the rear support part 6 of the saddle, the pressing head 2, and the two saddle beam straightening blocks 8 are all formed by 3D printing.

[0042] The saddle beam straightener also includes a start switch 15 for operating the vertical pressing cylinder 12 and the horizontal pushing cylinder 9. The start switch 15 is a two-hand start switch to ensure that employees operate in a standard standing posture and prevent crushing injuries.

[0043] The air intake and exhaust of the two horizontally pushing cylinders 9 are controlled by the first solenoid valve 16, and the air intake and exhaust of the vertically pressing cylinder 12 are controlled by the second solenoid valve 17. Both the first solenoid valve 16 and the second solenoid valve 17 are controlled by a programmable controller 18 to control the movement of the three cylinders, thereby achieving full automation.

[0044] The vertically pressing cylinder 12 is connected to a first air pipe 19 for controlling forward movement and a second air pipe 20 for controlling backward movement. The two horizontally pushing cylinders 9 are respectively connected to a third air pipe 21 for controlling forward movement and a fourth air pipe 22 for controlling backward movement. The third air pipe 21 and the fourth air pipe 22 are both connected to and controlled by the first solenoid valve 16. The first air pipe 19 and the second air pipe 20 are both connected to and controlled by the second solenoid valve 17. The first solenoid valve 16 and the second solenoid valve 17 are both supplied with air through the main air passage 23.

[0045] Usage process:

[0046] 1. Based on the actual needs of correcting the shape of the saddle, the front support part 4, the rear support part 6, the pressing head 2, and the two saddle beam correction blocks 8 are manufactured by 3D printing and installed on the support platform.

[0047] 2. Based on the actual correction needs of the saddle, set the positions of the inner displacement limit rod and the outer displacement limit block.

[0048] 3. Place the saddle on the saddle beam straightening seat. The front and rear parts of the saddle are respectively placed into the front support part of the saddle and the rear support part of the saddle beam. A portion of the straight section in the middle of the lower part of the saddle beam is correspondingly inserted into the saddle beam slots above the two saddle beam straightening blocks. In this way, the saddle and the saddle beam below it are fixed.

[0049] 4. The horizontal push cylinders located on both sides of the two saddle beam straightening blocks are driven synchronously to adjust the horizontal spacing of the middle opening of the saddle beam and the parallelism of the saddle beam as needed by pushing inward or pulling outward. Then, the pressing head is pressed down by the vertical pressing cylinder to press the saddle seat and correct the bending deformation of the saddle beam, thereby completing the precise straightening of the saddle beam.

[0050] 5. After the correction is completed, the vertical pressing cylinder will reset first, then the two horizontal pushing cylinders will reset, and finally the product will be removed.

[0051] When the bolt serving as the inner displacement limit rod is tightened, it is used to fix the displacement of the horizontal push cylinder after it is pulled outward and then retracted; after the outer displacement limit block is adjusted to a suitable position, it is used to fix the displacement of the horizontal push cylinder after it is pushed inward and then stopped.

[0052] The descent and reset of the vertically pressing cylinder 12 are controlled by the second solenoid valve 17, and the inward, outward, and reset of the two horizontally pushing cylinders 9 are controlled by the first solenoid valve 16. In addition, the programmable controller 18 controls the actions of the first solenoid valve 16 and the second solenoid valve 17 to control the movement of the three cylinders, thereby achieving full automation.

[0053] The high-stability multi-angle saddle beam straightener of this invention features high efficiency, high precision, good flexibility, safety, good stability, and convenient operation throughout the straightening process. The front support, rear support, pressing head, and two saddle beam straightening blocks of the saddle can be flexibly replaced according to the specific saddle structure, thus adapting to the straightening of various types of saddle products. It has a high degree of automation, which is conducive to improving the quality of the saddle. Moreover, it does not rely on the operator's experience, saving time and effort, greatly improving the efficiency of subsequent saddle installation and ensuring the stability of the saddle, making it extremely practical.

[0054] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
