Description

Technical Field

[0001] This utility model relates to the field of automated equipment processing technology, and in particular to a snapping mechanism for an automatic riveting machine. Background Technology

[0002] In the automatic riveting equipment industry, the snap-fit ​​mechanism is the core actuator that enables the final pressing of the claw snap and the bottom snap. Its performance directly determines the impact force, stability, and lifespan of the riveting process. Conventional snap-fit ​​mechanisms typically use a motor in conjunction with a transmission system consisting of a travel screw, crank, and connecting rod to convert the motor's rotary motion into the linear reciprocating motion of the upper die.

[0003] The existing transmission solutions described above have significant limitations. First, the transmission chain structure, formed by multiple components connected in series, is bulky, occupies a large space, and is not conducive to equipment miniaturization. Second, multiple hinge points suffer from accumulated assembly errors, and after long-term operation, wear can easily create gaps, leading to inaccurate snapping actions, reduced impact force, and affecting riveting quality. Furthermore, the complex structure also results in higher manufacturing costs and greater maintenance difficulty. Although some improvement schemes have been proposed, they have not fundamentally simplified the structural complexity of the transmission chain.

[0004] Existing technologies rely heavily on complex transmission chains composed of multiple components to achieve motion conversion, resulting in cumbersome structures and poor maintainability. Utility Model Content

[0005] The main purpose of this utility model is to propose a snapping mechanism for an automatic riveting machine, which aims to solve the technical problems of existing technologies that rely on complex transmission chains composed of multiple components to achieve motion conversion, resulting in bulky structures and poor maintainability.

[0006] To achieve the above objectives, this utility model proposes a snap-fit ​​mechanism for an automatic riveting machine, comprising an upper die snap-fit ​​driving component and an upper die snap-fit ​​component. A snap-fit ​​transmission assembly is provided between the upper die snap-fit ​​driving component and the upper die snap-fit ​​component. The snap-fit ​​transmission assembly includes a snap-fit ​​eccentric wheel and a support base. The snap-fit ​​eccentric wheel is connected to the output end of the upper die snap-fit ​​driving component. The support base is fixed at the eccentric position of the snap-fit ​​eccentric wheel. The upper die snap-fit ​​component is connected to the support base. When the upper die snap-fit ​​driving component rotates, it can drive the upper die snap-fit ​​component to perform a periodic eccentric rotational motion through the snap-fit ​​eccentric wheel and the support base, thereby generating a vertically downward snap-fit ​​force.

[0007] Furthermore, the support base and the upper mold buckle component are rotatably connected.

[0008] Furthermore, the upper die buckle component includes a base and a clamp. A fixing rod extends from the bottom of the base, and the clamp is located below the base and is used to clamp the claw buckle.

[0009] Furthermore, the clamp includes a first jaw and a second jaw respectively disposed on both sides of the fixed rod, and the fixed rod, the first jaw, and the second jaw together limit the jaw lock.

[0010] Furthermore, the seat body is equipped with a cushioning structure to buffer the periodic snapping action.

[0011] Furthermore, the buffer structure includes a guide rod and a spring.

[0012] Furthermore, a sliding part is provided on the side of the seat, and an anti-slapping component is provided through the sliding part.

[0013] Furthermore, the anti-slapping hand assembly includes anti-slapping hand guards and a slide block, wherein the anti-slapping hand guards are slidably connected to the sliding part via the slide block.

[0014] Furthermore, a protective gear drive component is provided above the anti-striking hand guard.

[0015] Furthermore, the protective gear's driving component is a cylinder.

[0016] This utility model relates to an upper mold snap-fit ​​driving component and an upper mold snap-fit ​​component. Specifically, a snap-fit ​​transmission assembly consisting of a snap-fit ​​eccentric wheel and a support base is provided between the driving component and the snap-fit ​​component. The support base is fixed at the eccentric position of the eccentric wheel and connected to the snap-fit ​​component. When the driving component rotates, the rotational motion is converted into the periodic eccentric rotational motion of the snap-fit ​​component through the eccentric wheel and the support base, thereby generating a vertically downward snap-fit ​​force. This utility model adopts a simple eccentric wheel transmission structure, replacing a complex multi-link mechanism, and has the advantages of compact structure, reliable operation, low wear, and easy maintenance.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0026] This utility model proposes a snapping mechanism for an automatic riveting machine.

[0027] In this embodiment of the utility model, such as Figures 1 to 4As shown, the snap-fit ​​mechanism includes an upper die snap-fit ​​driving component 1 and an upper die snap-fit ​​component 2, configured such that the upper die snap-fit ​​component 2 is driven by the upper die snap-fit ​​driving component 1 to apply a vertically downward force. The upper die snap-fit ​​driving component 1 is preferably a motor. A snap-fit ​​transmission assembly 3 is provided between the upper die snap-fit ​​driving component 1 and the upper die snap-fit ​​component 2. The upper die snap-fit ​​component 2 is eccentrically connected to the output end of the motor through the snap-fit ​​transmission assembly 3, so that the rotation center of the upper die snap-fit ​​component 2 does not coincide with the rotation center of the motor. The upper die snap-fit ​​mechanism 3 is configured such that, driven by the upper die snap-fit ​​driving component 1, it rotates eccentrically through the snap-fit ​​transmission assembly 3 and performs periodic downward and return movements. It should be emphasized that this utility model uses the above structure to replace the complex transmission chain commonly found in the prior art, which consists of a stroke screw, crank, and connecting rod. Existing technical solutions require multiple components to convert rotational motion into linear motion, resulting in problems such as bulky structure, complex assembly, numerous friction points, and susceptibility to gaps and wear. This invention directly realizes the periodic downward and return motion of the upper die buckling component 2 by transmitting the rotational action of the motor through the buckling transmission component 3, thereby saving assembly and simplifying the overall structure.

[0028] Specifically, the buckle transmission assembly 3 includes a buckle eccentric wheel 31 and a support base 32. The support base 32 is fixedly connected to the buckle eccentric wheel 31 and moves with the buckle eccentric wheel 31 as it rotates. The support base 32 is connected to the upper die buckle component 2. The support base 32 mainly serves to enhance the stability of the connection.

[0029] Specifically, the upper die snapping component 2 includes a base 21 and a clamp 22. A fixing rod 211 extends from the bottom of the base 21. The clamp 22 is located below the base 21 and is used to grip the snap-on clip. The clamp 22 includes a first jaw 221 and a second jaw 222 respectively located on both sides of the fixing rod 211. The fixing rod 211, the first jaw 221, and the second jaw 222 together limit the snap-on clip. The base 21 has a buffer structure 213 inside to cope with the periodic snapping action. The buffer structure 213 mainly uses a guide rod 2131 and a spring 2132 to form a buffer.

[0030] Specifically, the seat 21 has a sliding part 212 on its side, and an anti-slapping component 214 is provided in cooperation with the sliding part 212. The anti-slapping component 214 includes an anti-slapping guard 2141 and a slide block 2142. The anti-slapping guard 2141 is slidably connected to the sliding part 212 via the slide block 2142. A guard driving component 2143 is also provided above the anti-slapping guard 2141. The guard driving component 2143 is preferably a cylinder.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
