Technical Field

[0001] This application relates to the field of mechanical automation processing equipment technology, and in particular to an automatic riveting device for piston rods of two-wheeled vehicles. Background Technology

[0002] In the braking or suspension systems of two-wheeled vehicles, such as motorcycles and electric vehicles, the piston rod, as a key transmission component, often requires riveting to fix the connecting parts at its end.

[0003] Traditional piston rod riveting equipment is mostly semi-automated, requiring manual operation of feeding, positioning, and removing the workpiece after riveting. After riveting, the piston rod needs to be manually removed from the tooling and sorted and stacked by the operator, which not only consumes human resources, but also limits the production cycle to the speed of manual operation, making it difficult to match the operating efficiency of high-speed riveting equipment. Meanwhile, the equipment needs to apply high pressure during the riveting process, and when the parts are picked up manually at close range, safety accidents such as mechanical clamping and workpiece splashing may occur due to operational errors or equipment failures.

[0004] In other words, existing technologies have the following technical problems: ordinary piston rod riveting equipment has low efficiency when operated manually during material cutting. Therefore, to address the above problems, an automatic piston rod riveting device for two-wheeled vehicles is proposed. Summary of the Invention

[0005] This embodiment provides an automatic piston rod riveting device for two-wheeled vehicles to solve the problem of low efficiency of manual operation when cutting materials in ordinary piston rod riveting devices in the prior art.

[0006] According to one aspect of this application, an automatic riveting device for piston rods of two-wheeled vehicles is provided, comprising: a processing platform, wherein a riveter is fixedly connected to one side of the upper surface of the processing platform; A rotary fixture is also fixedly connected to the upper surface of the processing platform.

[0007] Furthermore, the circular rotary table is disposed on the upper surface of the tooling base and is rotatably connected to the tooling base, while the tooling base is fixedly disposed on the upper surface of the processing platform.

[0008] Furthermore, a plurality of placement sleeves are provided, and the plurality of placement sleeves are arranged in a ring array on the upper surface of the circular rotating platform. The placement sleeves are provided with holes that match the size of the piston rod, for inserting the piston rod and positioning it stably.

[0009] Furthermore, the rotary tooling is driven to rotate by a drive assembly, which consists of a drive part, an ejector part, and a positioning component. Several ratchet teeth are fixedly provided on the arc-shaped wall of the circular rotary table. The number of ratchet teeth is the same as that of the sleeve and they correspond one-to-one. One end of the drive part is fixedly connected to the upper surface of the processing platform, and the ejector part is fixedly connected to one end of the drive part. One end of the ejector part extends to the ratchet teeth.

[0010] Furthermore, the pusher head is made of wear-resistant alloy material, and its front end is wedge-shaped, matching the shape of the ratchet teeth.

[0013] Furthermore, a limiting ring is fixedly connected at the bottom wall of the inner cavity of the sleeve.

[0014] Furthermore, the spray structure includes a fixed pipe and a bend. The bottom end of the fixed pipe is fixedly connected to the upper surface of the processing platform.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] Please see Figure 1-6 As shown, an automatic riveting device for piston rods of two-wheeled vehicles includes: a processing platform 1, wherein a riveter 2 is fixedly connected to one side of the upper surface of the processing platform 1; A rotary fixture 3 is also fixedly connected to the upper surface of the processing platform 1. The rotary fixture 3 consists of a circular rotary table 302 and a placement sleeve 303. The placement sleeve 303 is used to place and insert the piston rod 7. The bottom of the rotary tooling 3 is equipped with an ejection structure 6, which is used to automatically eject the processed piston rod 7. The unloading assembly 5 is fixedly installed on the side of the rotary tooling 3. The unloading assembly 5 consists of an unloading slide plate 501 and a spraying structure. The spraying structure is used to spray the ejected piston rod 7 onto the unloading slide plate 501.

[0021] To address the problem that conventional piston rod riveting equipment in the prior art requires manual unloading and storage of the riveted piston rod, which is labor-intensive and poses certain dangers, this application designs a rotary tooling 3 and an unloading assembly 5. Through the cooperation of the rotary tooling 3 and the unloading assembly 5, the piston rod 7 can be automatically riveted and unloaded simultaneously, thereby saving manpower. During unloading, the unloading position of the piston rod 7 can be effectively controlled, ensuring accurate unloading after ejection. This design is particularly suitable for processing piston rods 7.

[0022] The circular rotary table 302 is disposed on the upper surface of the tooling base 301 and is rotatably connected to the tooling base 301, while the tooling base 301 is fixedly disposed on the upper surface of the processing platform 1.

[0023] Several placement sleeves 303 are provided, and the placement sleeves 303 are arranged in a ring array on the upper surface of the circular rotating platform 302. The placement sleeves 303 are provided with holes that match the size of the piston rod 7, for inserting the piston rod 7 and positioning it stably. The rotation of the circular rotating platform 302 can drive the placement sleeves 303 to rotate, which in turn drives the piston rod 7 to rotate to a position directly below the riveter 2, where the riveter 2 performs riveting processing on the piston rod 7.

[0024] The rotary tooling 3 is driven to rotate by a drive assembly 4, which consists of a drive unit 402, an ejector unit 403, and a positioning component. A plurality of ratchet teeth 401 are fixedly provided on the arc-shaped wall of the circular rotary table 302. The number of ratchet teeth 401 is the same as and corresponds one-to-one with the placement sleeve 303. One end of the drive unit 402 is fixedly connected to the upper surface of the processing platform 1, and the ejector unit 403 is fixedly connected to one end of the drive unit 402. One end of the ejector unit 403 extends to the ratchet teeth 401. In this technical solution, the extension and retraction of the drive unit 402 can drive the ejector unit 403 to reciprocate. The ejection of the ejector unit 403 can push the ratchet 401 to move, thereby driving the circular rotary table 302 to rotate. Each ejection can only push one ratchet 401, so that the rotation angle of the circular rotary table 302 can be controlled, so that it rotates at a fixed angle each time, thereby driving the placement sleeve 303 to rotate at a fixed angle. This facilitates the control of the movement position of the piston rod 7 and makes it convenient for riveting processing.

[0025] Specifically, the pusher head is made of wear-resistant alloy material, and its front end is wedge-shaped, matching the tooth groove shape of the ratchet 401.

[0026] Preferably, the drive unit 402 can be an electric cylinder or an electric push rod.

[0027] Furthermore, the stroke of the drive unit 402 is matched with the pitch of the ratchet 401. Each action pushes the ratchet by exactly one pitch, causing the circular rotary table 302 to rotate by a fixed angle α, where α = 360° / n, and n is the number of sleeves 303 placed. The positioning component includes a latch 406 and a fixed cylinder 404. The fixed cylinder 404 is fixedly mounted on the upper surface of the processing platform 1. A movable push rod 405 is slidably connected in the inner cavity of the fixed cylinder 404. One end of the movable push rod 405 is fixedly connected to the latch 406. The latch 406 extends to the groove position of the ratchet 401. One end face of the latch 406 is beveled. A support spring 407 is provided between the fixed cylinder 404 and the movable push rod 405. One end of the movable push rod 405 is fixedly connected to one end of the support spring 407. The other end of the support spring 407 is fixedly connected to the inner wall of the fixed cylinder 404. Through this technical solution, the latch 406 can be used to position the circular rotary table 302, so that each rotation is controlled within the range of the ratchet 401. When the ratchet 401 rotates, it can compress the latch 406, causing it to push the moving push rod 405 to retract. After the ratchet 401 passes the latch 406, the support spring 407 allows the latch 406 to re-enter the gap of the ratchet 401, achieving automatic positioning. Specifically, the support spring 407 is a stainless steel compression spring, whose preload is greater than the impact force caused by the inertia of the rotary table, but less than the maximum thrust of the drive unit 402, ensuring positioning without affecting rotational propulsion.

[0028] The ejection structure 6 includes an ejection cylinder 601 and an ejector rod 602. The ejection cylinder 601 is fixedly mounted on the bottom surface of the processing platform 1, and the ejector rod 602 is fixedly connected to the upper end of the ejection cylinder 601. The ejector rod 602, the bottom surface of the placement sleeve 303, and the circular rotary table 302 are all provided with insertion holes for the ejector rod 602 to enter. Preferably, the ejection cylinder 601 is a double-acting cylinder, and its lifting action is controlled by a solenoid valve. The top end of the ejector rod 602 is provided with a soft rubber cap to prevent scratching the end face of the piston rod 7 during ejection. A limiting ring 304 is also fixedly connected to the bottom wall of the inner cavity of the placement sleeve 303. Furthermore, the inner diameter of the limiting ring 304 is slightly smaller than the diameter of the piston rod 7 body but larger than the diameter of the top end of the push rod 602, so that the piston rod 7 is suspended after insertion, which facilitates the push rod 602 to act on it. Through this technical solution, the extension of the ejector cylinder 601 can drive the push rod 602 to move upward, so that the upper end of the push rod 602 lifts the bottom end of the piston rod 7, causing the piston rod 7 to be ejected, thereby separating the piston rod 7 from the placement sleeve 303.

[0029] The spray structure includes a fixed pipe 502 and a bend 503. The bottom end of the fixed pipe 502 is fixedly connected to the upper surface of the processing platform 1. The upper end of the fixed pipe 502 passes through the tooling base 301 and the circular rotary table 302 and is rotatably engaged with the circular rotary table 302. The top end of the fixed pipe 502 is fixedly connected to the bend 503, and the upper end of the bend 503 points towards the unloading slide plate 501. Specifically, during operation, the fixed pipe 502 is connected to an external air source, which can be a blower. Specifically, the air source provides compressed air at 0.4–0.6 MPa, with an airflow velocity sufficient to blow the piston rod 7 to the discharge slide plate 501 and slide it into the collection box. After the gas enters the fixed pipe 502, it is output from the upper end of the bend 503. When the piston rod 7 is pushed out, due to the action of the airflow, the piston rod 7 deviates towards the discharge slide plate 501 and falls down, so that the piston rod 7 can fall onto the discharge slide plate 501 and discharge through the discharge slide plate 501 to realize the function of automatic discharge.

[0030] Preferably, the equipment is also equipped with a PLC control system, which is electrically connected to the drive unit 402, the ejector cylinder 601 and the air source solenoid valve to realize automatic cyclic control of rotation, riveting, ejection and blowing.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
