Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to a lower module lifting mechanism. Background Technology

[0002] Riveting machines, also known as button attaching machines, are widely used in garment factories and leather goods processing enterprises. They are primarily used to attach various types of metal buttons to knitted garments, down jackets, denim clothing, shoes, hats, and leather products. Buttons typically consist of upper and lower buttons, which are attached to the front and back of the fabric respectively and riveted together using a riveting machine. When attaching buttons to fabric, holes are usually punched in the fabric first, and then the upper and lower buttons are riveted together. This requires the lower die of the riveting machine to switch positions to achieve different operations.

[0003] In existing technologies, guide rail or linkage structures are generally used to control the movement of the lower working die, thereby achieving the switching of the lower working die position. However, these methods require regular calibration and replacement of sealing rings, and require high operator skills. At the same time, the parallelism and levelness of the guide rail or linkage need to be precisely calibrated, otherwise it is easy to cause jamming or uneven wear. If the table surface of the lower working die is uneven, the lower rivet placed on the upper table surface of the lower working die can easily shift, resulting in the lower rivet not being able to accurately align with the upper rivet during riveting, making it difficult to guarantee the quality of riveting. The existing lower die lifting mechanism has the technical defect of not being able to achieve both precise adjustment and convenient maintenance. Utility Model Content

[0004] The main purpose of this utility model is to propose a lower module lifting mechanism, which aims to solve the technical problem that the existing lower module lifting mechanisms cannot achieve both precise adjustment and convenient maintenance.

[0005] To achieve the above objectives, this utility model proposes a lower module lifting mechanism, which is installed in the lower module structure of a riveting machine and used to drive the lower module structure to perform lifting actions, including:

[0006] Drive components;

[0007] The vertical moving parts are connected to the driving parts via a transmission mechanism. The vertical moving parts include a first actuating part and a second actuating part for respectively driving the lower module structure alignment riveting and alignment buckle; and...

[0008] Limiting components are used to support vertically moving parts.

[0009] Furthermore, the vertical moving parts and the driving parts are rotatably connected, and the driving parts are defined as rotary motors.

[0010] Furthermore, the first actuating part is defined as a protruding structure provided on the up-and-down moving part.

[0011] Furthermore, the first action part includes a first action surface and a second action surface, and the first action surface and the second action surface are defined as arc surfaces.

[0012] Furthermore, the arc shape of the first working surface is recessed towards the inside of the vertical moving parts, while the arc shape of the second working surface protrudes towards the outside of the vertical moving parts.

[0013] Furthermore, the second action part is defined as a cylindrical structure disposed on the vertical moving part. The second action part includes a raised arc surface and a concave arc surface with a height difference, and the raised arc surface and the concave arc surface have connected endpoints.

[0014] Furthermore, the limiting assembly includes a first frame and a second frame, the up-and-down moving component abuts between the first frame and the second frame, and the up-and-down moving component can rotate between the first frame and the second frame.

[0015] Furthermore, a coupling is provided between the drive component and the upper and lower moving components. One end of the coupling is connected to the drive component, and the other end is connected to the upper and lower moving components through a connecting rod, which passes through the upper and lower moving components.

[0016] Furthermore, the limiting component is equipped with a sensing component for detecting the origin position of the moving parts. The sensing component includes a sensor and a sensing bracket. The sensor is fixedly mounted on the sensing bracket, and the sensing bracket is fixedly connected to the limiting component.

[0017] Furthermore, the limiting component is equipped with a perforated pad.

[0018] This utility model's technical solution includes a first and a second working part in the upper and lower moving parts, which respectively drive the lower module structure to align and rivet, and align and snap. The upper and lower moving parts are supported by a limiting component, and after the upper and lower moving parts move through the driving component, the first and second working parts respectively drive the working lower module to switch between the rivet and snap positions. Because this utility model uses a single mechanical module of the upper and lower moving parts to switch the working lower module to different working positions, it can achieve precise adjustment and is also conducive to daily maintenance. This utility model has the beneficial effects of precise adjustment and convenient maintenance. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

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.

[0032] This utility model proposes a lower module lifting mechanism.

[0033] In this embodiment of the utility model, such as Figures 1 to 8 As shown, the lower module lifting mechanism is installed in the lower module structure (not shown) of the riveting machine and is used to drive the lower module structure to perform lifting and lowering actions. It includes a driving component 1, an up-and-down moving component 2, and a limiting component 3 for supporting the up-and-down moving component 2. The up-and-down moving component 2 is connected to the driving component 1 through a transmission. The up-and-down moving component 2 includes a first action part 21 and a second action part 22 for driving the lower module structure to align for riveting and to align for fastening, respectively. After the up-and-down moving component 2 is driven by the driving component 1, the first action part 21 and the second action part 22 abut against the lower module structure during the movement, thereby switching the position of the lower module structure so that the lower module structure can perform more precise riveting and fastening actions at the predetermined position.

[0034] In some embodiments of this utility model, the up-and-down moving part 2 and the driving part 1 are rotatably connected. The driving part 1 is defined as a rotary motor, which can be specifically a stepper motor. The advantage of stepper motors is that they move smoothly and quietly, and can be adapted to the use of riveting machines. At the same time, compared with servo motors, stepper motors have lower costs, which is beneficial to saving industrial costs for enterprises.

[0035] Specifically, the first actuating part 21 is defined as a protruding structure provided on the upper and lower moving parts 2. The first actuating part 21 lifts the lower module structure by colliding with the protrusion, thereby achieving precise riveting. Please refer to [reference needed]. Figures 5 to 8 To understand the content, among which Figures 6 to 8 This is an example of the state of the upper and lower moving parts 2 as it rotates over time. During this process, specifically when the lower module structure abuts against the first actuating part 21... Figures 6 to 7The content is as follows: First, the protruding structure of the first action part 21 is located on the side. Then, with the rotation of the upper and lower moving parts 2, the first action part 21 moves towards the middle. At this time, the lower module structure is lifted by the contact of the first action part 21, thus realizing the switching of the height of the lower module structure, enabling it to perform riveting work precisely.

[0036] More specifically, the first action part 21 includes a first action surface 211 and a second action surface 212, and the first action surface 211 and the second action surface 212 are defined as arc surfaces. Defining the two surfaces formed by the protrusion of the first action part 21, namely the first action surface 211 and the second action surface 212, as arc surfaces is beneficial to the smooth movement of the lower module structure, while reducing the wear caused by collision with the lower module structure, which is beneficial to the improvement of service life.

[0037] Furthermore, in order to lift the lower module structure more smoothly and gently, the arc of the first action surface 211 is recessed towards the inside of the upper and lower moving parts 2, while the arc of the second action surface 212 protrudes towards the outside of the upper and lower moving parts 2. The inwardly recessed first action part 21 can lift the lower module structure more gently when it collides with it.

[0038] Specifically, the second actuating part 22 is defined as a cylindrical structure disposed on the upper and lower moving parts 2. The second actuating part 22 includes a raised arc surface 221 and a concave arc surface 222 with a height difference, and the raised arc surface 221 and the concave arc surface 222 have connected endpoints. When the lower module structure is located at the second actuating part 22, after the upper and lower moving parts 2 rotate, the lower module structure switches from a state of abutting against the raised arc surface 221 to a state of abutting against the concave arc surface 222. At this time, the lower module structure lowers its height, achieving the purpose of precise fastening. Please refer to [reference needed]. Figures 5 to 8 To understand the content, among which Figures 6 to 8 This is an example of the state of the upper and lower moving parts 2 as it rotates over time. During this process, specifically when the lower module structure abuts against the second actuating part 22... Figure 7 and Figure 8 The process involves the raised arc surface 221 abutting against the lower module structure, followed by the recessed arc surface 222 abutting against the lower module structure. This allows the lower module structure to achieve a smooth, gentle, and precise descent. This is understandable, as it works on the same principle as the first action part 21. In practice, the lower module structure switches between two points. By switching between these points, the height of the lower module structure can be precisely limited, thus meeting the precision requirements of riveting.

[0039] Understandably, the above embodiment mainly involves the up-and-down moving component 2 changing the position of the first action part 21 and the second action part 22 by rotating itself, thereby causing a change in the height of the lower module structure being abutted. The lower module structure then moves horizontally through its own drive structure to contact the first action part 21 and the second action part 22, rather than being limited to rotation. In fact, the up-and-down moving component 2 can horizontally set the first action part 21 and the second action part 22 on the up-and-down moving component 2, and the drive component 1 can use a cylinder to push horizontally, thereby achieving a similar technical effect. Since the structure is similar, it will not be described in detail here.

[0040] In some embodiments of this utility model, the limiting component 3 includes a first frame 31 and a second frame 32, the up-and-down moving component 2 abuts between the first frame 31 and the second frame 32, and the up-and-down moving component 2 can rotate between the first frame 31 and the second frame 32. The main function of the limiting component 3 for the up-and-down moving component 2 is to provide support, and the movement process of the up-and-down moving component 2 can be more stable.

[0041] In some embodiments of this utility model, a coupling 4 is provided between the drive component 1 and the up-and-down moving component 2. One end of the coupling 4 is connected to the drive component 1, and the other end is connected to the up-and-down moving component 2 through a connecting rod 5. The connecting rod 5 passes through the up-and-down moving component 2, which is adapted to the high working stability required for riveting work. The coupling 4 can eliminate the shaft misalignment problem caused by manufacturing errors, thermal deformation or installation deviation through flexible connection, and avoid component wear, bearing overload or transmission failure caused by stress concentration under rigid connection, thereby significantly improving the reliability and service life of the drive component 1 and the up-and-down moving component 2.

[0042] In some embodiments of this utility model, the limiting component 3 is equipped with a sensing component 6 for detecting the origin position of the up-and-down moving part 2. The sensing component 6 includes a sensor 61 and a sensing bracket 62. The sensor 61 is fixedly mounted on the sensing bracket 62, and the sensing bracket 62 is fixedly connected to the limiting component 3. Through the sensor 61, this utility model can perform an orderly working cycle, which is beneficial to the stability required for riveting work.

[0043] In some embodiments of this utility model, the limiting component 3 is equipped with a punching pad 7. It can be understood that the lower module structure usually includes two parts: a riveting part and a punching part. When the lower module structure is pushed out, the punching part is often placed in a suspended position. The punching pad 7 at the limiting component 3 can make the movement of the punching part more stable and enhance the stability of the punching-riveting step.

[0044] 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.
