Description

Technical Field

[0001] This invention belongs to the field of servo press-fitting technology, specifically a servo radial press. Background Technology

[0002] In the field of servo press technology, traditional servo presses have been widely used in the axial press operations of various parts. With the high-precision position and force control capabilities of the servo system, they perform well in unidirectional press operations.

[0003] However, for fasteners such as "rivet screws" that require radial extrusion forming of their heads, traditional servo presses cannot directly achieve radial synchronous pressing because their motion is limited to the axial direction. They often need to rely on additional transverse drive modules or multi-axis independent servo systems for motion conversion.

[0004] While such improvement schemes can achieve radial motion, they generally lead to complex equipment structures, extended transmission chains, and increased motion inertia. This not only reduces the dynamic response speed and energy efficiency of the system, but also complicates the synchronous control between multiple pressure heads. It is difficult to ensure that each pressure head contacts the screw head simultaneously and evenly during the pressing process, which can easily cause quality problems such as uneven force, riveting deformation, or inconsistent indentation depth, affecting the assembly reliability and appearance consistency of the rivet screws.

[0005] In addition, for rivet screws of different specifications, the head size, forming angle and pressing force requirements are different. Existing radial pressing mechanisms often lack flexible and adjustable mechanical structures, resulting in poor process adaptability, long changeover and debugging cycles, and difficulty in meeting the flexible production needs of small batches and multiple varieties.

[0006] Therefore, in the radial press-fitting application of rivet screws, there is an urgent need for a servo press-fitting device that is compact, has direct transmission, can be controlled synchronously with high precision, and is easy to adjust in order to solve the systemic technical problems of structural redundancy, poor synchronization, and inconvenient adjustment in traditional solutions, and improve press-fitting quality and production efficiency.

[0013] A linear reciprocating drive mechanism is mounted on the assembly plate;

[0014] The radial press-fitting assembly includes:

[0015] A fixed track component is located below the mounting plate. The output end of the linear reciprocating drive mechanism is connected to the fixed track component. The linear reciprocating drive mechanism drives the fixed track component to move up and down.

[0016] At least two sliding press-fitting parts are slidably disposed on each of the guide parts in a one-to-one correspondence, and each sliding press-fitting part is detachably mounted with a press head;

[0017] The number of motion conversion mechanisms is the same as that of the sliding press-fitting parts and they correspond one-to-one. The two ends of the motion conversion mechanism are respectively hinged to the mounting plate and the corresponding sliding press-fitting part.

[0018] When the fixed track component moves along the axial direction of the fixed track component under the drive of the linear reciprocating drive mechanism, the motion conversion mechanism drives each of the sliding press-fit components to move synchronously in opposite directions or in opposite directions along the corresponding guide portion in a radial motion.

[0019] In the above technical solution, preferably, the driving unit includes a cylinder and a stabilizing slide, the piston rod of the cylinder is connected to the stabilizing slide, the frame includes a vertically arranged guide column frame, the mounting plate is provided with a linear bearing that slides with the guide column frame, the linear bearing is located on the stabilizing slide, and the assembly plate is fixedly mounted on the mounting plate through a support column passing through the guide column frame.

[0020] In the above technical solution, preferably, the linear reciprocating drive mechanism includes a servo motor, a driving pulley, a driven pulley, a synchronous belt surrounding the driving pulley and the driven pulley, and a lead screw; the servo motor is mounted on the mounting plate, the driving pulley is connected to the output shaft of the servo motor, the lead screw is rotatably connected to the mounting plate, the driven pulley is connected to one end of the lead screw, and a floating connection mechanism is drivenly connected to the lead screw, the floating connection mechanism passing through the mounting plate and connected to the fixed track component.

[0022] In the above technical solution, preferably, the slider is provided with a protrusion that matches the cross-sectional shape of the inclined groove, and the protrusion is embedded in the inclined groove to form a tenon-and-mortise sliding fit.

[0023] In the above technical solution, preferably, the motion conversion mechanism includes connecting rods, one end of each connecting rod is hinged to the mounting plate, and the other end is hinged to the corresponding slider. The center of the circular track disk is provided with an axially extending pressure column, and the upper end of the pressure column is fixedly connected to the mounting plate.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By setting a single linear reciprocating drive mechanism to drive the axial movement of the fixed track component, and utilizing multiple sets of motion conversion mechanisms to synchronously convert the axial displacement into the radial movement of each sliding pressing component, a mechanical synchronous drive for multiple pressing heads is achieved. This design requires only one servo power source to complete multi-directional precision pressing, abandoning the traditional multi-axis independent drive system, greatly simplifying the mechanical structure, reducing control complexity, and ensuring that each pressing head maintains strict synchronization and uniform force application during radial movement. This effectively solves problems such as uneven workpiece force and inconsistent forming caused by timing or displacement differences in multi-point pressing.

[0029] 2. To adapt to the head size, forming angle and pressing force requirements of workpieces of different specifications, the pressing head can be quickly disassembled and replaced through a quick-change interface. The fixed track component is a complete replaceable type, or the radial displacement and pressing force characteristics can be flexibly changed by adjusting the geometric parameters of its guide part, so as to adapt to diverse process requirements. This design enhances the process flexibility of the equipment, shortens the debugging time when changing products, and supports flexible production of small batches and multiple varieties.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1 to 9 As shown, the present invention provides a servo radial press, comprising:

[0045] Frame 1 and lifting device 2 mounted on frame 1;

[0046] The lifting device 2 includes a drive unit 3, an assembly plate 4 and a mounting plate 5 that are slidably mounted on the frame 1;

[0047] The drive unit 3 drives the assembly plate 4 and mounting plate 5 to move vertically up and down along the frame 1;

[0048] A linear reciprocating drive mechanism 6 is mounted on the assembly plate 4;

[0049] The radial press-fitting assembly includes:

[0050] The fixed track component 7 is located below the mounting plate 5. The output end of the linear reciprocating drive mechanism 6 is connected to the fixed track component 7. The linear reciprocating drive mechanism 6 drives the fixed track component 7 to move up and down. The inner wall of the fixed track component 7 is provided with at least two guide parts 8, and an assembly hole is formed between the guide parts 8.

[0051] At least two sliding press-fitting parts 9 are slidably disposed on each guide part 8 in a one-to-one correspondence, and each sliding press-fitting part 9 is detachably mounted with a press head 10;

[0052] The number of motion conversion mechanisms 11 is the same as that of sliding press-fit parts 9 and they correspond one-to-one. The two ends of the motion conversion mechanism 11 are respectively hinged to the mounting plate 5 and the corresponding sliding press-fit parts 9.

[0053] When the fixed track component 7 is driven by the linear reciprocating drive mechanism 6 to move along the axial direction of the fixed track component 7, the motion conversion mechanism 11 drives each sliding press component 9 to move radially in opposite directions or in opposite directions along the corresponding guide portion 8.

[0054] like Figure 3 As shown, the drive unit 3 includes a cylinder 24 and a stabilizing slide 25. The piston rod of the cylinder 24 is connected to the stabilizing slide 25. The frame 1 includes a vertically arranged guide column frame 12. The mounting plate 5 is provided with a linear bearing 13 that slides with the guide column frame 12. The linear bearing 13 is located on the stabilizing slide 25. The assembly plate 4 is fixedly mounted on the mounting plate 5 through the support column passing through the guide column frame 12.

[0055] The cylinder 24 has a simple, reliable, low-cost, and high load capacity. The guide column 12 and the linear bearing 13 work together to form a linear guide, which ensures the smoothness and vertical accuracy of the assembly plate 4 under heavy load, and provides a stable reference platform for the upper precision pressing.

[0056] like Figure 2 , Figure 3 , Figure 4 As shown, the linear reciprocating drive mechanism 6 includes a servo motor 14, a drive pulley 15, a driven pulley 16, a synchronous belt 17 surrounding the drive pulley 15 and the driven pulley 16, and a lead screw 18; the servo motor 14 is mounted on the mounting plate 4, the drive pulley 15 is connected to the output shaft of the servo motor 14, the lead screw 18 is rotatably connected to the mounting plate 4, the driven pulley 16 is connected to one end of the lead screw 18, and a floating connection mechanism 19 is drivenly connected to the lead screw 18, which passes through the mounting plate 5 and is connected to the fixed track component 7;

[0057] Among them, the assembly plate 4 is also equipped with a tensioning wheel, which is used to tension the synchronous belt 17 to ensure the transmission effect;

[0058] The synchronous belt 17 transmission features buffering, vibration reduction, and low noise, protecting the servo motor 14 from impact; it allows for a larger center distance, facilitating overall layout; combined with the high-precision lead screw 18, it ultimately achieves smooth, accurate, and efficient rotary-linear motion conversion.

[0059] like Figure 5 , Figure 7 , Figure 9 As shown, the fixed track component 7 is a circular track disk, the guide part 8 is an inclined groove opened on the track disk, and the sliding pressing component 9 includes a slider 20 that slides in cooperation with the inclined groove, and the pressing head 10 is installed on the slider 20.

[0060] The circular track disk has a symmetrical and compact structure that can evenly distribute the pressing force. The inclined slide is the geometric basis for motion conversion, and its angle determines the conversion ratio of axial displacement to radial displacement. The design is flexible, and this structure is a direct and effective mechanical carrier for realizing the synchronous radial movement of multiple pressure heads.

[0061] The slider 20 is provided with a protrusion 21 that matches the cross-sectional shape of the inclined slide groove. The protrusion 21 is embedded in the inclined slide groove to form a tenon-and-mortise sliding fit, which has high connection rigidity, large contact area, strong load-bearing capacity, and is not prone to gaps and shaking. This ensures high precision and stability during the pressing process, similar to the constraint method of a guide rail. It has high guiding accuracy, low wear, long service life, and a certain self-centering ability.

[0062] The motion conversion mechanism 11 includes connecting rods 22. One end of each connecting rod 22 is hinged to the mounting plate 5, and the other end is hinged to the corresponding slider 20. It is a mechanism that converts linear motion into oscillating or linear motion. Its mechanical characteristics are clear and its transmission efficiency is high. Multiple sets of connecting rods act independently on each slider 20, ensuring the synchronicity of the movement of multiple pressure heads 10 and realizing one-axis input and multi-path output.

[0063] The circular track disk has an axially extending pressure column 23 at its center. The upper end of the pressure column 23 is fixedly connected to the mounting plate 5. The pressure column 23 firstly plays an auxiliary role in centering the workpiece. Secondly, during the pressing process, it can withstand the possible axial component force or provide central support for the workpiece, making the overall force distribution more reasonable, protecting the moving parts such as connecting rods from unexpected axial loads, and improving the rigidity and service life of the mechanism.

[0064] The floating connection mechanism 19 includes a movable plate 33 that is threadedly engaged with the lead screw 18 of the linear reciprocating drive mechanism 6, and a connecting column 34 whose two ends are respectively connected to the fixed track 7 and the movable plate 33. The connecting column 34 passes through a through hole provided on the mounting plate 5 and slides in engagement with the through hole.

[0065] This mechanism allows for a certain degree of axial floating or soft connection between the circular track disk and the mounting plate 5, which bears the main driving force. This helps to compensate for manufacturing and assembly errors or minor dimensional differences in the workpiece itself, prevents the mechanism from jamming due to over-positioning, and improves the fault tolerance and operational reliability of the equipment.

[0066] It also includes a lead screw support unit 35, which includes a bearing seat 36 mounted on the mounting plate 5 and the assembly plate 4. The lead screw 18 is supported in the bearing seat 36 by a bearing 37, providing stable rotational support for the lead screw 18. This greatly improves the rigidity, rotational accuracy, and smoothness of the lead screw transmission system, and reduces deflection and vibration. This is the basis for ensuring the linear motion accuracy of the mounting plate 5 and the control accuracy of the entire pressing process, and also extends the service life of the lead screw.

[0067] The pressure head 10 is detachably mounted on the sliding pressing component 9 via the quick-change interface 38. The quick-change interface 38 is a pin-type or flange-type connection structure, which improves the flexibility and production efficiency of the equipment. Operators can quickly change pressure heads of different shapes, sizes or materials without using complicated tools to adapt to different product models or pressing process requirements, thus realizing rapid changeover in production.

[0068] like Figure 10 , Figure 11 , Figure 12As shown, the fixed track component 7 has an oil storage chamber 26 and at least one lubrication distribution chamber 27 formed along its axial direction inside. The oil storage chamber 26 is connected to the lubrication distribution chamber 27 through an oil drip hole 28. An oil seepage hole 29 is provided between the lubrication distribution chamber 27 and the inclined groove of the guide part 8. The lubrication distribution chamber 27 is filled with a porous material block 30. The porous material block 30 has an extension. The extension is located in the oil seepage hole 29 and contacts the surface of the slider 20. The extension of the porous material block 30 is detachably connected to the porous material block 30 for easy replacement. An oil injection hole 31 is provided on the top of the fixed track component 7, which is connected to the oil storage chamber 26. The oil injection hole 31 is connected to a spiral elastic oil injection pipe 32. The other end of the oil injection pipe 32 extends to the rear side of the frame 1 and is connected to the oil pump. The spiral elastic oil injection pipe 32 can effectively absorb and compensate for the reciprocating motion of the assembly plate 4 during operation, avoid fatigue cracking of rigid pipes due to repeated bending or loosening of joints, and ensure the long-term reliability of the external oil pump oil supply path.

[0069] The specific lubrication process is a working mode that combines intermittent adaptive oil replenishment with continuous penetration lubrication. Specifically, the external oil pump does not continuously supply oil, but replenishes lubricating oil to the oil storage chamber 26 intermittently through the elastic oil injection pipe 32 according to the equipment running time, cycle or monitoring signal. The lubricating oil is first stored in the oil storage chamber 26, and then slowly flows into the lubrication distribution chamber 27 through the drip hole 28. The porous material block 30 filled in the lubrication distribution chamber 27 uses its capillary adsorption to evenly distribute the oil and keep it in the internal pores of the material, forming a stable lubricating oil reserve.

[0070] Through the multi-stage slow-release structure of oil storage chamber 26, oil drip hole 28, lubrication distribution chamber 27, and oil seepage hole 29, the lubricating oil can continuously, stably, and evenly penetrate to the working surface of the slide groove under the capillary action of the porous material block 30. This overcomes the problem of uneven lubrication or temporary oil shortage that may be caused by intermittent oil injection. The porous material block 30 contacts the surface of the slider 20, and its capillary action can achieve lubrication on demand. Especially when the equipment is frequently started and stopped or running at high speed, it can effectively reduce wear.

[0071] Working principle and usage process of this invention:

[0072] When the lifting device 2 is activated, the mounting plate 5 and the assembly plate 4 are driven to rise or fall smoothly along the guide column frame 12 on the frame 1, thereby quickly adjusting the entire servo drive and press-fitting execution system installed on it to a preset height position that is compatible with the workpiece to be processed, so as to realize the alignment between the equipment and the workpiece.

[0073] After positioning is completed, the servo motor 14 works, and its output torque is transmitted to the lead screw 18 in sequence through the driving pulley 15, the synchronous belt 17, and the driven pulley 16, forming a first-stage reduction and power transmission. The rotational motion of the lead screw 18 is converted into the linear motion of the moving plate 33, which is threadedly engaged with it, along the axial direction of the equipment.

[0074] When the moving plate 33 moves downward or upward in a straight line, it drives the fixed track 7 to move up and down through the connecting column 34. Since the slider 20 is constrained in a specific inclined groove on the fixed track 7 through multiple sets of connecting rods 22 that are hinged to it, the axial linear motion of the mounting plate 5 is decomposed and converted into multiple sliders 20 moving synchronously in opposite directions or in opposite directions along the radius of the circular track disk according to the design of the inclined direction of the groove. Finally, the pressure head 10 installed on the slider 20 applies radial compression or release to the workpiece located in the central area.

[0075] During lubrication, an external oil pump can replenish lubricating oil into the oil storage chamber 26 through a spiral elastic oil injection pipe 32 and an oil injection hole 31. Under the influence of gravity and capillary action, the lubricating oil slowly and evenly permeates into the lubrication distribution chamber 27 below through the drip hole 28. The porous material block 30 filled in the oil storage chamber 26 and the lubrication distribution chamber 27 adsorbs and retains the oil through capillary action. The porous material block 30 extends into the seepage hole 29 and contacts the surface of the slider 20. Through continuous capillary action, the lubricating oil is evenly delivered to the mating interface between the slider 20 and the inclined groove, forming a stable oil film and achieving on-demand, adaptive, and long-lasting lubrication.
