Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing and automation, in particular to a multifunctional flexible press-fitting device. Background Art

[0002] The flexible press-fitting device is a press-fitting device with flexible control characteristics, which is mainly used in the press-fit assembly process of parts. Its core advantage lies in achieving a precise and stable press-fitting process through flexible control technology, avoiding part damage or assembly errors that may be caused by rigid press-fitting.

[0003] In modern manufacturing, press-fitting technology, as a key assembly link, is widely used in many fields such as automobile manufacturing, electronic equipment production, and mechanical processing. With the rapid development of the manufacturing industry and the increasing demand for product diversification and personalization, the limitations of traditional press-fitting equipment have become increasingly prominent, making it difficult to meet the needs of efficient, precise, and flexible production.

[0004] Existing pressing equipment also has shortcomings in pressing quality control. Many traditional equipment use gas-liquid booster cylinders and other methods for pressing, which makes it difficult to accurately control the pressing depth and force. During the pressing process, problems such as inadequate pressing and over-pressing are prone to occur, affecting the assembly quality and performance of the product, increasing the intensity of manual operation, reducing the level of automation, and making it difficult to ensure the consistency of product quality.

[0005] To this end, the present invention provides a multifunctional flexible press-fitting device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip, and the toothed connecting strip is connected with said toothed connecting strip to form a bottom surface.

[0008] An inner gasket is sleeved in the accommodating cavity of the limiting sleeve, and a folded edge is provided on the lower surface of the inner gasket. The folded edge of the lower surface of the inner gasket is placed on the stepped end of the top of the accommodating cavity, and a spring is fixedly installed on the inner bottom wall of the inner gasket.

[0009] One end of the spring away from the inner washer is fixedly mounted on the inner top wall of the limiting sleeve, the inner arc surface of the spring is sleeved on the outer arc surface of the waist-shaped groove, and the outer side wall of the stepped end is in contact with a connecting kit.

[0010] The outer arc surface edge of the connecting sleeve is provided with a protruding edge, the lower surface of the protruding edge is provided with a clamping tube, the outer arc surface of the clamping tube is provided with a gap, the outer arc surface of the clamping tube is an elastic structure, and the upper surface of the connecting sleeve is provided with a wedge-shaped end.

[0011] The inner arc surface of the wedge-shaped end is movably abutted against a positioning component, and the positioning component includes a compression sleeve abutting against the inner top wall of the wedge-shaped end, and the upper surface of the compression sleeve is provided with a U-shaped edge end.

[0012] The U-shaped edges are placed between each other at one end of the connecting sleeve. A positioning hole is provided on the U-shaped edge of the upper surface of the compression sleeve. A locking shaft is connected through the inner arc surface of the positioning hole. One end of the locking shaft passes through the outside of the compression sleeve and abuts against the inner top wall of the connecting sleeve.

[0013] A replacement component is sleeved on the bottom of the outer arc surface of the pin shaft, and an inner arc surface of the replacement component passes through the bottom of the pin shaft and is connected to an outer washer. Contact grooves are provided on both sides of the outer arc surface of the replacement component.

[0014] A cushion block is sleeved on the inner arc surface of the contact groove, and an outer convex end is provided in the middle of one side surface of the cushion block, and one side of the outer convex end extends to the outer arc surface of the contact groove.

[0015] An elastic arm is provided on the other side of the cushion block, one side of the elastic arm abuts against the outer arc surface of the pin shaft, and one side of the outer convex end fits with the inner arc surface of the clamping cylinder.

[0016] There are two pads, which are distributed on both sides of the replacement component in a mirror-symmetrical manner. The replacement component and the air push rod are in the same plane, and the replacement component is sleeved into the interior of the clamping cylinder.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The cooperation between the positioning component and the connection kit ensures that the press-fit components maintain a stable and precise position during the press-fitting process. The flexible adjustment of the press-fitting force by the limit sleeve and the spring can control the press-fitting error within a very small range. Whether it is the micro-assembly of precision electronic components or the high-precision press-fitting of key components of automobile engines, it can effectively avoid product performance degradation or scrapping caused by press-fitting deviation, and greatly improve the product yield and reliability.

[0019] 2. The drive system composed of air push rods and pneumatic rods can quickly and stably move the press-fitting components to the specified position and perform the press-fitting operation. The quick replacement design of replacement parts enables the equipment to switch between press-fitting tasks of different products in a short time, reducing equipment idle time. The efficient collaboration between various components significantly shortens the production cycle of a single product, increases the output per unit time, and strongly supports large-scale production and rapid delivery needs.

[0020] 3. The press-fitting assembly uses springs to achieve flexible press-fitting. Combined with the diverse adaptability of replacement parts, the equipment is compatible with the press-fitting of parts of different materials, sizes and shapes. From brittle materials such as plastics and ceramics to high-strength metal parts, press-fitting can be completed by adjusting equipment parameters and replacing adapter parts, expanding the application scenarios of the equipment and meeting the needs of enterprises for diversified product production.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1 、 Figure 2 and Figure 3 The cam 62 is fixedly mounted on the top of the support frame 1, and a support rod 62 is fixedly mounted on the top of the support frame 1. The support rod 62 is fixedly mounted on the top of the support frame 1, and a side connecting plate 2 is fixedly mounted on both sides of the upper end of the support rod 62 at the top of the support frame 1. A gas push rod 3 is fixedly mounted on the surface of one side of the side connecting plate 2. One end of the gas push rod 3 is fixedly mounted on the seat plate 4. A gas pressure rod 5 is fixedly mounted on the upper surface of the seat plate 4. A press-fit assembly 6 is fixedly mounted on one end of the gas pressure rod 5. The press-fit assembly 6 includes a pin shaft 61 fixedly mounted on one end of the gas pressure rod 5. The top of the outer arc surface of the pin shaft 61 is sleeved with a limiting sleeve 62. The middle part of the upper surface of the limiting sleeve 62 is provided with a waist-shaped groove 621. The inner arc surface of the waist-shaped groove 621 is provided with an accommodating cavity 622. The lower surface of the limiting sleeve 62 is provided with a stepped end 623. The inner arc surface of the waist-shaped groove 621 is connected with the pin shaft 61. The outer arc surface edge of the limiting sleeve 62 is provided with a deformation skirt 624. The deformation skirt 624 on the outer arc surface of the positioning sleeve 62 is placed on the circumference of the gas pressure rod 5, and an inner gasket 63 is sleeved in the accommodating cavity 622 of the limiting sleeve 62, and the lower surface of the inner gasket 63 is provided with a folded edge, and the folded edge of the lower surface of the inner gasket 63 is placed on the stepped end 623 at the top of the accommodating cavity 622, and a spring 65 is fixedly installed on the inner bottom wall of the inner gasket 63, and the end of the spring 65 away from the inner gasket 63 is fixedly installed on the inner top wall of the limiting sleeve 62, the inner arc surface of the spring 65 is sleeved on the outer arc surface of the waist-shaped groove 621, and the outer side wall of the stepped end 623 abuts against the connecting kit 64, and a protruding edge 641 is provided at the edge of the outer arc surface of the connecting kit 64, and a clamping tube 642 is provided on the lower surface of the protruding edge 641, and a gap 643 is opened on the outer arc surface of the clamping tube 642, and the outer arc surface of the clamping tube 642 is an elastic structure, and a wedge-shaped end 644 is provided on the upper surface of the connecting kit 64.

[0032] Take the support frame 1 as the basic bearing structure of the device, and stably weld or fix the support crossbar on the upper surface of the support frame 1 through high-strength bolts to form a stable upper support structure. On the outer sides of the two ends of the support crossbar at the top of the support frame 1, the side connecting plates 2 are vertically fixed respectively by using bolts to ensure that the side connecting plates 2 and the support frame 1 maintain good verticality and stability, and to provide reliable support for subsequent component installation. The side connecting plates 2 are vertically placed on the outer sides of the two ends of the support crossbar at the top of the support frame 1, and are connected by bolts. Appropriate size bolts are used to sequentially pass through the corresponding mounting holes on the side connecting plates 2 and the support frame 1, and then nuts are tightened. When tightening the nuts, the diagonal tightening method is also adopted, and the torque is gradually increased in multiple times to ensure that the side connecting plates 2 are stably and vertically fixed on the support frame 1, thereby providing a reliable vertical support surface for the installation of subsequent drive assemblies and other components.

[0033] On the opposite side surface of the side connecting plate 2, the air push rod 3 is horizontally fixed by using the matching mounting hole and the bolt. The installation of the air push rod 3 needs to ensure that the extension direction and the pressing direction are consistent to realize stable horizontal thrust transmission. The extension end of the air push rod 3 is tightly connected with the seat plate 4 through bolts or flanges to ensure that it will not loosen or displace during operation. The air pressure rod 5 is vertically installed on the center position of the upper surface of the seat plate 4, and is also fixed by bolts or special clamps. The extension axis of the air pressure rod 5 is perpendicular to the extension direction of the air push rod 3 to form a mutually cooperating drive system.

[0034] When the pressing process is started, the air pressure rod 5 extends downward to transmit driving force to the pin shaft 61. The pin shaft 61 is a key hub for force transmission, and transmits pressure to the limiting sleeve 62. Since the limiting sleeve 62 is connected with the pin shaft 61 through the waist-shaped groove 621, and the outer arc surface edge is provided with a deformation skirt 624 wrapped around the air pressure rod 5, in the initial stage of force transmission, the deformation skirt 624 deforms by utilizing its own elasticity to preliminarily buffer the instantaneous impact force, thereby reducing the impact caused by rigid contact and avoiding direct damage to workpieces or device components. When the pressure is further transmitted to the inside of the limiting sleeve 62, the spring 65 in the accommodating cavity 622 begins to play a core buffering role. One end of the spring 65 is fixed to the inner bottom wall of the inner gasket 63, and the other end is fixed to the inner top wall of the limiting sleeve 62 and is sleeved on the outer arc surface of the waist-shaped groove 621. As the pressing force increases, the spring 65 is compressed, absorbs excess pressure energy through elastic deformation, and converts the rigid pressing force into a flexible and adjustable force. In this process, the compression amount of the spring 65 is related to the size of the pressing force. Springs 65 with different elastic coefficients can adapt to different pressing needs, ensuring that when precise components or thin-walled parts are pressed, the parts will not be deformed or damaged due to excessive pressure, and achieving precise and flexible control of the pressing force.

[0035] As Figure 4 , Figure 5 and Figure 6As shown, the inner arc surface of the wedge-shaped end 644 is movably abutted against the positioning component 7, and the positioning component 7 includes a compression sleeve 71 abutting against the inner top wall of the wedge-shaped end 644, and the upper surface of the compression sleeve 71 is provided with a U-shaped edge end 711, and the U-shaped edge ends 711 are placed between each other at one end of the connecting sleeve 64, and the upper surface of the compression sleeve 71 is provided with a positioning hole 712 on the U-shaped edge end 711, and the inner arc surface of the positioning hole 712 is penetrated and connected with a locking shaft 72, and one end of the locking shaft 72 passes through the outside of the compression sleeve 71 and abuts against the inner top wall of the connecting sleeve 64.

[0036] The positioning assembly 7 is mainly composed of a clamping sleeve 71 and a locking shaft 72. The upper surface of the clamping sleeve 71 is provided with a U-shaped edge end 711, which is adapted to the end shape of the connecting sleeve 64. During assembly, the clamping sleeve 71 is placed in the wedge-shaped end 644 of the connecting sleeve 64, and the U-shaped edge end 711 is stuck in the edge of one end of the connecting sleeve 64 to form a preliminary limiting fit. This pre-positioning design enables the clamping sleeve 71 to be accurately in the predetermined position, laying the foundation for subsequent tightening and stabilization work, while also limiting the horizontal movement tendency of the connecting sleeve 64. The locking shaft 72 is the core component for realizing the stable function of the positioning assembly 7. After the clamping sleeve 71 is preliminarily positioned by the U-shaped edge end 711, the locking shaft 72 is passed through the positioning hole 712 on the clamping sleeve 71, and one end of the locking shaft is extended to the inner top wall of the connecting sleeve 64.

[0037] When locking sill 75 and locking sill 77 are positioned between latching in the indented portion 74 and the engagement of latch 7 with the engagement of the base 62, the locking sill 77 will snap back and forth and lock the base 62 together, thereby firmly locking sill 75 in place and preventing any damage to the base 62. Under the action of the pressing force, the contact surface between the wedge-shaped end 644 and the clamping sleeve 71 will generate a mutual squeezing force. This force enables the clamping sleeve 71 to constrain the connecting sleeve 64 along a specific direction, thereby ensuring that the connecting sleeve 64 maintains a precise position in the vertical direction. At the same time, since the clamping cylinder 642 is sleeved on the outside of the stepped end 623 of the limiting sleeve 62, the close fit between the positioning assembly 7 and the connecting sleeve 64 indirectly constrains the movement of the limiting sleeve 62, ensuring that the entire pressing assembly 6 will not deviate or shake during the pressing process, so that the pressing head can press the workpiece along a precise trajectory, ensuring the high precision of the pressing position and the stability of the pressing quality.

[0038] like Figure 7As shown, a replacement component 8 is sleeved on the bottom of the outer arc surface of the pin shaft 61, and an inner arc surface of the replacement component 8 passes through the bottom of the pin shaft 61 and is connected to an outer gasket 9. Contact grooves 81 are provided on both sides of the outer arc surface of the replacement component 8, and a gasket 82 is sleeved on the inner arc surface of the contact groove 81. An outer convex end 83 is provided in the middle of one side surface of the gasket 82, and one side of the outer convex end 83 extends to the outer arc surface of the contact groove 81. An elastic arm 84 is provided on the other side of the gasket 82, and one side of the elastic arm 84 abuts on the outer arc surface of the pin shaft 61, so one side of the outer convex end 83 fits with the inner arc surface of the clamping tube 642. There are two gaskets 82, and the two gaskets 82 are distributed on both sides of the replacement component 8 in a mirror-symmetrical manner. The replacement component 8 and the air push rod 3 are in the same plane, and the replacement component 8 is sleeved to the inside of the clamping tube 642.

[0039] The replacement component 8 adopts a sleeve design and is installed from the bottom of the pin 61 upward. Its inner diameter fits tightly with the bottom of the pin 61, and can be firmly installed by interference fit or key connection. This installation method does not require complex tools and tedious steps. It only needs to align the replacement component 8 with the bottom of the pin 61 and insert it to complete the initial positioning, which greatly shortens the replacement time. At the same time, the contact grooves 81 opened on both sides of the replacement component 8 are used in conjunction with the gasket 82. One side of the elastic arm 84 of the gasket 82 abuts against the outer arc surface of the pin 61, and the elastic force of the elastic arm 84 is used to provide additional fastening force to ensure that the position of the replacement component 8 on the pin 61 is stable to prevent loosening or falling off during equipment operation.

[0040] After the replacement component 8 is installed in place, the outer protruding end 83 of the pad 82 in the contact groove 81 will extend to the outer arc surface of the contact groove 81 and fit tightly with the inner arc surface of the clamping tube 642 of the connecting kit 64. Since the outer arc surface of the clamping tube 642 is an elastic structure and has a gap 643, moderate squeezing of the clamping tube 642 during the installation process to reduce its inner diameter can further enhance the clamping force on the outer protruding end 83 of the pad 82. This close contact fit and clamping locking mechanism allows the replacement component 8 to form a stable whole with the entire press-fit assembly 6. During the press-fitting process, the pressure borne by the replacement component 8 can be accurately transmitted to the limiting sleeve 62 and other components through the pad 82 and the clamping tube 642, ensuring the effective transmission of the press-fitting force and the stability of the press-fitting process, while also ensuring that the replacement component 8 will not undergo relative displacement during operation.

[0041] During the pressing process, the replacement component 8 can perform a certain degree of dynamic adaptation according to the actual working conditions. Since the elastic arm 84 of the pad 82 has the ability of elastic deformation, when there is a certain fluctuation in the pressing force or there is a slight unevenness on the workpiece surface, the elastic arm 84 can be deformed for buffering and adjustment, so that the replacement component 8 maintains a good contact state with the workpiece surface, avoiding pressing deviation or workpiece damage caused by rigid contact. At the same time, this dynamic adaptive characteristic also helps to disperse the pressing force, so that the pressing force acts more evenly on the workpiece, further ensuring the stability and consistency of the pressing quality.
