Description

Technical Field

[0001] This utility model relates to a mechanical device, and more particularly to a lifting and pressing mechanism used in product processing or assembly. Background Technology

[0002] In today's highly industrialized era, product processing and assembly efficiency and quality have become key factors for enterprises to stand firm in market competition. In the traditional product pressing operation field, the pressing and lifting mechanisms typically have many limitations. A common design combines the lifting and pressing power sources in a linear layout. This layout forces the lifting power source to overcome significant pressing resistance during operation, necessitating reliance on high-power drive devices. This not only significantly increases equipment procurement costs and operating energy consumption but also triggers a series of related problems. For example, high-power drive devices are often bulky, occupying excessive production space and hindering compact production line layout and optimized integration. Furthermore, the output stability of the power source is difficult to control precisely, especially under conditions of fluctuating motor speed or unstable hydraulic system pressure, directly leading to unstable pressing forces.

[0003] Furthermore, the force distribution of rollers in traditional lifting modules during the pressing process has inherent defects. Taking an automatic capping device disclosed in Chinese Publication No. CN217756827U as an example, the cam-structured rollers in its lifting module must bear the pressing force during the pressing process. Due to the unreasonable structure and force distribution, local stress concentration is prone to occur. This not only results in uneven wear on the roller surface, greatly accelerating the wear rate and shortening its service life, but also further affects the rolling accuracy of the rollers, thereby interfering with the smoothness of the entire lifting module's movement.

[0004] Therefore, overcoming the above-mentioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0005] This utility model overcomes the aforementioned technical shortcomings and provides a lifting and pressing mechanism. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A lifting and pressing mechanism includes a lifting module 1 and a pressing module 2, characterized in that the lifting module 1 includes a first driving device 11 installed along the Y-axis direction, a cam mechanism 12 that converts the Y-axis force from the first driving device 11 into the Z-axis force, and a lifting and pressing platform 13 on which the product is placed, installed above the cam mechanism 12 and driven by the cam mechanism 12 to move along the Z-axis.

[0007] The cam mechanism 12 includes: a cam block 121 driven by a first driving device 11 and reciprocating on the Y-axis; a roller 122 moving along the surface of the cam block 121; and a driven block 123 moving together with the roller 122.

[0008] Preferably, the driven block 123 has a groove 231 on one side of its bottom for the roller (122) to be installed therein, and a support portion 232 is formed on the other side of its bottom.

[0009] Preferably, the cam block 121 has a plane 211 at the top, and a first inclined surface 212 and a second inclined surface 213 extending obliquely downward from the front and rear of the plane 211, respectively; wherein the plane 211 is used to contact the support part 232 of the driven block 123 to receive force, the first inclined surface 212 enables the roller 122 to roll, and the second inclined surface 213 enables the roller 122 to be suspended and not subjected to force; when the roller 122 is on the first inclined surface 212, the lifting and pressing platform 13 is in the initial position; when the roller (132) rolls upward along the first inclined surface 212, the lifting and pressing platform 13 performs a lifting movement; when the roller (132) is on the plane 211, the lifting and pressing platform 13 completes the lifting, at which time the roller (132) is above the second inclined surface 213.

[0010] Preferably, a slider seat 3 is provided below the cam block 121, and a slide groove 31 is provided in the slider seat 3, and the cam block 121 is slidably fitted in the slide groove 31.

[0011] Preferably, the lifting module 1 further includes a fixed base 14, a first vertical shaft 15, and a second vertical shaft 16; the slider seat 3 has three first vertical shafts 15 arranged in a triangle connected on both sides of the slide groove 31; the fixed base 14 is installed above the cam block 121 by means of the three first vertical shafts 15; and the lifting and pressing platform 13 is installed above the fixed base 14 by means of several second vertical shafts 16 in a sliding fit.

[0012] Preferably, a plurality of return springs 17 are installed between the lifting and pressing platform 13 and the fixed base 14.

[0013] Preferably, a first limiter 18 is provided in front of the cam block 121 to prevent it from moving excessively; a second limiter 19 is installed in front of the lifting and pressing platform 13 to stop the product placed on it.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] 1. This utility model achieves reasonable force distribution on the roller 122 at different stages through the unique design of the cam mechanism 12. During lifting, the roller 122 rolls in contact with the first inclined surface 212, reducing friction and distributing the force; after lifting is completed, the support part 232 and the top surface 212 are subjected to force, and the roller 122 is suspended, avoiding long-term pressure wear, effectively extending the service life of the roller 122 and related components, while ensuring the lifting module's ability to withstand high pressure, thus improving the overall reliability and stability of the mechanism.

[0018] 2. This utility model organically integrates the lifting module 1 and the pressing module 2, optimizing the layout and connection method of each component. For example, the compact design of components such as the cam mechanism 12 and the lifting and pressing platform 13 in the lifting module 1, and the reasonable layout of components such as the mounting base 6 and the second drive device 22 in the pressing module 2, effectively reduce the volume of the entire mechanism, save equipment space, and facilitate the compact layout of the production line and the miniaturization of the equipment. At the same time, the smaller structural volume also reduces the manufacturing and transportation costs of the equipment.

[0019] 3. The layered design of the fixed base 14 and the lifting and pressing platform 13 in this utility model, combined with the triangular stable arrangement of the first vertical shaft 15 and the reasonable force-bearing design of the second vertical shaft 16 bearing, enables the mechanism to better resist external interference and maintain structural stability during operation. This reduces component wear and the risk of failure, further improves the reliability of the mechanism, ensures the accuracy and stability of the product pressing process, and helps to improve product quality and production efficiency.

[0023] Figure 4 This is a schematic diagram of the lifting module structure of this utility model; Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, to achieve the above objectives, this novel experimental design employs the following technical solutions:

[0026] 1. Initial state preparation

[0027] Before the equipment is started, all components are initially stationary. At this time, the lifting and pressing platform 13 of the lifting module 1 is at its lowest position, and the pressing seat 24 of the pressing module 2 is at its highest raised position, ensuring that the entire working area is free of obstructions and that all components are functioning normally without faults. At the same time, the first drive device 11 is in standby mode, ready to receive the start signal.

[0028] 2. Lifting process begins

[0029] Upon receiving the instruction to start working, the first drive unit 11 is activated, outputting power to push the cam block 121 to move along the slide groove 31 of the slider seat 3 in the Y-axis direction.

[0030] 3. From initial position to transition phase

[0031] As the cam block 121 moves, the roller 122, installed in the groove 231 of the driven block 123, rolls along the surface of the cam block 121. Initially, the roller 122 is located on the first inclined surface 212 of the cam block 121. At this stage, the driven block 123 maintains a relatively low position in the Z-axis direction, and the lifting and pressing platform 13 is also in an initial low position. The product is waiting for the lifting operation on the platform.

[0032] 4. Key Transition and Support Transformation

[0033] As the cam block 121 continues to move, the roller 122 gradually transitions from the first inclined plane 212 to the plane 211. Due to the continuous pushing of the cam block 121 and the interaction between the roller 122 and the plane 211, the driven block 123 gradually rises in the Z-axis direction until it reaches its highest point. During this process, the first drive device 11 continuously applies a stable thrust to ensure that the driven block 123 can rise smoothly to the designated position.

[0034] 5. Support structure switching and roller protection

[0035] After the driven block 123 rises to its highest point, as the cam block 121 moves further, the roller 122, under the action of the roller, begins to move relative to the plane 211, gradually moving away from the plane 211. Simultaneously, the support portion 232 on one side of the bottom of the driven block 123 contacts the plane 211 and bears force, beginning to support the weight of the driven block 123, the lifting and pressing platform 13, and the product. At this point, the roller 122 moves above the second inclined plane 213 and is suspended in the air. This design not only effectively protects the roller 122 from damage due to prolonged exposure to excessive pressure, but also, through the contact between the support portion 232 and the plane 211, enables the mechanism to withstand greater pressure, ensuring the stability and reliability of the lifting process.

[0036] 6. Pressing operation coordination

[0037] After the lifting and pressing platform 13 rises to the predetermined lifting position, the second drive device 22 of the pressing module 2 is activated, driving the pressing seat 24 downward through the floating joint 23 to perform a precise pressing operation on the lifted product. During the pressing process, the floating joint 23 can automatically adjust its position to compensate for any possible minor positional deviations, ensuring uniform contact and stable pressure between the pressing seat 24 and the product, thereby achieving a high-quality pressing effect.

[0038] 7. Reset operation performed

[0039] After the pressing operation is completed, the first drive device 11 drives the cam block 121 to move in the opposite direction. At this time, the lifting pressing platform 13 gradually descends under the pulling force of the return spring 17, and the driven block 123 also descends accordingly. The roller 122 transitions back from the second inclined plane 213 to the first inclined plane 212, and finally the entire mechanism returns to the initial state, ready for the next lifting pressing operation cycle.

[0040] Throughout the entire operation, the first limiter 18 in front of the cam block 121 and the second limiter 19 in front of the lifting and pressing platform 13 play crucial roles. The first limiter 18 precisely restricts the range of motion of the cam block 121, preventing it from damaging the equipment due to excessive movement; the second limiter 19 ensures that the product remains in the correct position during lifting and processing, avoiding displacement deviations, thereby guaranteeing the stable operation of the equipment and the processing quality of the product.

[0041] Through the above detailed implementation methods, the lifting and pressing mechanism of this utility model can efficiently, accurately and stably complete the lifting and pressing operation of the product, meet the actual needs in industrial production, and has significant practical value and advantages.
