Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically to a high-precision integrated machining equipment for non-standard screws. Background Technology

[0002] Non-standard bolts, due to their unique dimensions, threads, or head structures, cannot be mass-produced using standard parts. In existing technologies, the processing of non-standard bolts generally employs a single-piece, intermittent processing mode. Specifically, a short optical shaft, just long enough to process one bolt, is typically clamped onto a machine tool such as a CNC lathe. After completing all or part of the processing for that single bolt, it is unloaded, and then the next short optical shaft is clamped, and this cycle is repeated. This one-piece-per-material, processing, unloading, and loading cyclical mode results in a significant portion of the machine tool's effective processing time being consumed by auxiliary time (such as loading, positioning, and unloading), creating a bottleneck in production efficiency.

[0003] To complete all the processes for a non-standard bolt (such as turning the outer contour, machining threads, and drilling radial holes), it is usually necessary to transfer the workpiece between multiple machines or change the machining modules on the machine tools. This not only exacerbates the discreteness of the production process and the time loss, but also affects the consistency of machining accuracy due to multiple clamping. This traditional production mode cannot achieve the goal of continuously, automatically, and synchronously processing different processes at different stations after a long raw material is placed into the machine tool, just like a production line, thereby producing multiple non-standard bolts in sequence without interruption. The fundamental problem is that the equipment layout and process flow fail to integrate continuous material feeding with parallel operation of the process space.

[0004] Therefore, there is an urgent need for a specialized integrated processing equipment that can achieve one-time clamping of long materials, multi-station spatial distribution, parallel operation of processes, and continuous production of finished products, in order to break through the efficiency bottleneck of non-standard bolt processing and achieve efficient, high-quality, automated continuous production. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated processing equipment for non-standard bolts with high integration, good processing accuracy and high degree of automation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A high-precision, non-standard screw integrated processing equipment includes a machine base, which is provided with a slide rail, a first drive mechanism, and a second drive mechanism; a pushing mechanism, which includes a first bearing seat and a first clamping assembly, wherein the first bearing seat is slidably mounted on the slide rail of the machine base, and the first clamping assembly is rotatably mounted on the inner side of the first bearing seat via a bearing, and the first drive mechanism drives the pushing mechanism to slide on the machine base; a clamping mechanism, which includes a drive wheel, a second bearing seat, and a second clamping assembly, wherein the drive wheel is fixedly connected to the second clamping assembly, the second bearing seat is fixedly mounted on the machine base, and the second clamping assembly is rotatably mounted on the second bearing seat via the bearing; and a positioning mechanism, which includes a third bearing seat and a positioning pin. The third bearing seat is slidably mounted on the slide rail of the machine base. The positioning pin is rotatably mounted on the third bearing seat via a bearing. The second drive mechanism drives the positioning mechanism to slide on the machine base. The clamping mechanism is located between the pushing mechanism and the positioning mechanism, and the three are arranged coaxially. The positioning mechanism and the clamping mechanism are coupled to each other to form a clamping effect on the long raw material. The modular processing device includes a turning component, a thread processing component, a radial hole processing component, and a cutting component. Each of the modular processing devices is detachably mounted on the machine base. The pushing mechanism and the positioning mechanism cooperate to transport the long raw material in a step-by-step manner, so that different processing sections of the long raw material enter the processing component stations of the modular processing device in sequence.

[0008] Both the first clamping assembly and the second clamping assembly are pneumatic chucks, and the center line of the jaws of the pneumatic chuck coincides with the axis of the positioning pin.

[0009] The inner hole of the first clamping assembly is provided with rollers.

[0010] The drive wheel is connected to a drive motor fixed to the base via a synchronous belt.

[0011] The positioning pin has at least two positioning points on its end face that contacts the workpiece, and the profile of the positioning point cross-section is triangular.

[0012] The turning assembly includes a cutting tool and a cutting tool holder. The cutting tool has a first lead screw at its tail end and a rack-like structure on its side. The cutting tool holder is connected to a rack-like first support structure. The cutting tool is slidably connected to the cutting tool holder via the first lead screw. The first support structure is linked to the cutting tool via a first gear. The first support structure and the cutting tool form mutually canceling forces in the vertical direction.

[0013] The thread rolling assembly includes a thread rolling plate and a thread rolling plate fixing component. The thread rolling plate has a second lead screw at its tail end and a rack-like structure on its side. The thread rolling plate fixing component is connected to a rack-like second support structure. The thread rolling plate is slidably connected to the thread rolling plate fixing block through the second lead screw. The second support structure is linked to the thread rolling plate through a second gear. The second support structure and the thread rolling plate form mutually canceling forces in the vertical direction.

[0014] The radial hole machining assembly includes a drill bit and a drill bit base for fixing the drill bit.

[0015] The cutting tool holder, the thread rolling plate holder, and the drill bit base share a common lead screw moving assembly in the direction of movement parallel to the propulsion mechanism. The lead screw moving assembly is provided with limiters between each workstation. The first support structure and the second support structure are provided with ball bearings on their contact surfaces with the workpiece.

[0016] It also includes an intelligent control system that can coordinate the control of all motors on the base.

[0017] Compared with the prior art, the present invention has the following significant advantages:

[0018] 1. Enabled continuous assembly line production of long materials: Through the coordinated action of translational and non-translational clamping mechanisms, long materials can be clamped at once and moved step by step. The processing components at each fixed station operate synchronously on the corresponding shaft segments, realizing the continuous and automatic processing of multiple bolts from a single raw material, transforming the discrete single-piece production mode into a highly efficient assembly line mode, and significantly improving production efficiency.

[0019] 2. Ensures machining accuracy and process stability: The unique three-point coaxial clamping system provides precise positioning and stable machining for long shaft raw materials, effectively reducing vibration and deformation.

[0020] 3. Improved equipment versatility: Key processing functions are implemented using modular components, which are easy to replace, enabling the equipment to flexibly adapt to the processing of non-standard bolts of different specifications and making production changeover convenient.

Detailed Implementation

[0033] In the following description, the terms "one," "two," etc., are used for descriptive purposes only, intended to clearly illustrate the differences between multiple similar parts or states, and should not be construed as indicating or implying any limitation on their relative importance, order, or quantity.

[0034] The following detailed description of each claim in the present invention, in conjunction with the accompanying drawings and specific embodiments, illustrates its technical features and its role in the overall solution.

[0035] See Figures 1 to 8According to the present invention, a high-precision non-standard screw integrated processing equipment includes a base 1, which is provided with a slide rail 11, a first drive mechanism 12, and a second drive mechanism 13; a pushing mechanism 2, which includes a first bearing seat 21 and a first clamping assembly 22, wherein the first bearing seat 21 is slidably mounted on the slide rail 11 of the base 1, and the first clamping assembly 22 is rotatably mounted on the inner side of the first bearing seat 21 via a bearing, and the first drive mechanism 12 drives the pushing mechanism 2 to slide on the base 1; a clamping mechanism 3, which includes a drive wheel 31, a second bearing seat 32, and a second clamping assembly 33, wherein the drive wheel 31 is fixedly connected to the second clamping assembly 33, the second bearing seat 32 is fixedly mounted on the base 1, and the second clamping assembly 33 is rotatably mounted on the second bearing seat 32 via a bearing; and a positioning mechanism 4, which includes a third bearing seat 41 and a positioning pin. 42. The third bearing seat 41 is slidably mounted on the slide rail 11 of the machine base 1. The positioning pin 42 is rotatably mounted on the third bearing seat 41 through the bearing. The second drive mechanism 13 drives the positioning mechanism 4 to slide on the machine base 1. The clamping mechanism 3 is located between the push mechanism 2 and the positioning mechanism 4, and the three are arranged coaxially. The positioning mechanism 4 and the clamping mechanism 3 are coupled to each other to form a clamping effect on the long material raw material. The modular processing device 5 includes a turning component 51, a thread processing component 52, a radial hole processing component 53 and a cutting component 54. The turning component 51, the thread processing component 52, the radial hole processing component 53 and the cutting component 54 are detachably mounted on the machine base 1. The push mechanism 2 and the positioning mechanism 4 cooperate with each other to transport the long material raw material in a step-by-step manner, so that different processing sections of the long material raw material enter the work positions of each processing component of the modular processing device 5 in sequence.

[0036] effect:

[0037] The base 1 serves as the installation foundation and load-bearing platform for the entire equipment. Its rigid structure ensures the stable geometric reference of all moving parts and processing units, enabling the equipment to maintain long-term precision stability.

[0038] The slide rail 11 provides high-precision guidance for the linear motion of the propulsion mechanism 2 and the positioning mechanism 4, thereby ensuring the straightness of the long raw material during the feeding process. The first drive mechanism 12 and the second drive mechanism 13, as power units, can precisely control the moving distance and speed of the propulsion mechanism 2 and the positioning mechanism 4, realizing the step-by-step conveying of long materials.

[0039] The propulsion mechanism 2, serving as the initial clamping and feeding unit for long raw materials, can stably clamp the material and drive it forward during processing. The first bearing seat 21 is slidably mounted on the slide rail 11 of the machine base 1, allowing the entire clamping unit to move along a predetermined trajectory. The first clamping assembly 22 can perform the clamping action on one end of the long raw material. The first clamping assembly 22 is rotatably mounted inside the first bearing seat 21 via a bearing, enabling the clamped long raw material to rotate freely when needed (such as during turning or thread rolling) to adapt to the requirements of different processing techniques. The first drive mechanism 12 drives the propulsion mechanism 2 to slide on the machine base 1, realizing automatic and precise feeding of the entire clamping unit.

[0040] The clamping mechanism 3, as a rigid clamping and rotary drive unit of the core machining station, provides strong radial clamping force to resist cutting forces for key processes such as turning and thread rolling, and drives the workpiece to rotate. The drive wheel 31 receives and transmits external torque, and the second bearing seat 32 serves as a fixed support, rigidly anchoring the entire rotary clamping unit to the machine base 1. The second clamping assembly 33 can directly clamp the workpiece for machining. The drive wheel 31 is fixedly connected to the second clamping assembly 33, ensuring effective transmission of rotational power. The second bearing seat 32 is fixedly installed on the machine base 1, providing a rigid support point and ensuring machining accuracy. The second clamping assembly 33 is rotatably mounted on the second bearing seat 32 via bearings, allowing it to drive the workpiece to rotate in a fixed position.

[0041] The positioning mechanism 4, acting as a clamping and fixing support unit for the other end of the long raw material, can work in conjunction with the propulsion mechanism 2 to determine the axial position of the workpiece and provide fixed support during processing. This prevents the workpiece shaft from bending and deforming due to excessive overhang, transforming the traditional overhanging processing of CNC machine tools into a fixed-end processing method. The positioning ejector pin 42 can directly contact the end face of the workpiece and provide clamping force. The third bearing seat 41 is slidably mounted on the slide rail 11 of the machine base 1 and can be driven independently, not moving synchronously with the propulsion mechanism 2. The positioning ejector pin 42 is rotatably mounted on the third bearing seat 41 via a bearing and can rotate with the workpiece, avoiding scratching the workpiece. The second drive mechanism 13 drives the positioning mechanism 4 to slide on the machine base 1, realizing automatic adjustment of the clamping position.

[0042] The modular machining unit 5, as a collection of process units performing specific machining operations, integrates the discrete processes (turning, milling, drilling, and cutting) required for non-standard bolts onto a straight line, achieving parallelization of processes through spatial arrangement. The turning assembly 51, thread machining assembly 52, radial hole machining assembly 53, and cutting assembly 54 are responsible for shaping the bolt outline, machining threads, drilling radial holes, and separating the finished product from the long material, respectively. Furthermore, this assembly can be disassembled and reassembled according to processing requirements, achieving multi-functionality.

[0043] See Figure 1 According to the present invention, a high-precision integrated non-standard screw processing device is provided, in which the first clamping assembly 22 and the second clamping assembly 33 are both pneumatic chucks. The pneumatic chuck can provide fast, reliable, and uniform clamping force, which helps to improve the machine's cycle time and ensure processing consistency. The center line of the pneumatic chuck's jaws coincides with the axis of the positioning pin 42. This ensures that the theoretical axis of the long raw material remains unchanged throughout the entire processing, eliminating processing errors caused by misalignment of the reference points.

[0044] See Figure 2 According to the high-precision non-standard screw integrated processing equipment provided by the present invention, the inner hole of the first clamping component 22 is provided with rollers 221. When installing long materials, the rollers 221 can convert the sliding friction between the optical axis and the inner wall of the clamping mechanism 3 into rolling friction. This significantly reduces the pushing resistance, making the installation process of long materials easier and smoother, and effectively solving the problem of difficulty in inserting long materials under traditional methods.

[0045] See Figure 1 According to the present invention, a high-precision non-standard screw integrated processing equipment is provided, in which the drive wheel 31 is connected to the drive motor fixed on the machine base 1 via the synchronous belt 6. The drive motor is a rotational power source that can provide the rotational motion required by the workpiece during turning and thread forming. The synchronous belt 6 can not only adjust the reduction ratio, but also transmit torque in a smooth and low-noise manner, and has overload protection capability.

[0046] See Figure 3 , Figure 4 According to the present invention, a high-precision integrated non-standard screw processing device is provided, wherein the positioning pin 42 has at least two positioning points 421 on its end face that contacts the workpiece, and the profile of the positioning point 421 is triangular. The triangular profile of the positioning point 421 can form a stable point contact with the end face of the workpiece. Even when the working end face is not flat, it can still be effectively embedded and reliably centered. At the same time, multiple triangular edges can generate anti-rotation torque to prevent the workpiece from circumferentially rotating during non-rotating drilling operations, thereby enhancing the reliability of positioning.

[0047] See Figure 1 , Figure 5According to the present invention, a high-precision non-standard screw integrated machining equipment includes a turning assembly 51 comprising a turning tool 511 and a turning tool fixing block 512. The turning tool 511 has a first lead screw 513 at its tail end and a rack-like structure on its side. The turning tool fixing block 512 is connected to a rack-like first support structure 514. The turning tool 511 is slidably connected to the turning tool fixing block 512 via the first lead screw 513. The first support structure 514 is linked to the turning tool 511 via a first gear 515. The first support structure 514 and the turning tool 511 generate mutually canceling forces in the vertical direction. The first support structure 514 can further reduce the deformation of long raw materials during machining, further improve the machining progress, and counteract the vertical force generated by the turning tool 511. A nut is installed on the turning tool fixing block 512, and the nut is connected to the first lead screw 513. A motor drives the nut to rotate, realizing the linear forward and backward movement of the turning tool 511. The self-locking characteristic of the lead screw drive ensures the stability of the feed position during machining.

[0048] See Figure 1 , Figure 6 According to the present invention, a high-precision non-standard screw integrated processing equipment is provided. The thread processing component 52 includes a thread rolling plate 521 and a thread rolling plate fixing member 522. The tail of the thread rolling plate 521 is provided with a second lead screw 523. The side of the thread rolling plate 521 is provided with a rack-like structure. The thread rolling plate fixing member 522 is connected to a rack-like second support structure 524. The thread rolling plate 521 is slidably connected to the thread rolling plate fixing member 522 through the second lead screw 523. The second support structure 524 is linked with the thread rolling plate 521 through a second gear 525. The second support structure 524 and the thread rolling plate 521 form mutually canceling forces in the vertical direction. The second support structure 524 can further reduce the deformation of long raw materials during processing, further improve the processing progress, and counteract the vertical force generated by the thread rolling plate 521. A nut is installed on the thread rolling plate fixing part 522, and the nut is connected to the second lead screw 523. The motor drives the nut to rotate to realize the linear advance and retreat of the thread rolling plate 521, which can accurately control the pressure and depth of thread forming, making the thread rolling feed control more direct and precise.

[0049] See Figure 1 , Figure 7 According to the present invention, a high-precision integrated non-standard screw processing device includes a radial hole processing assembly 53 comprising a drill bit 531 and a drill bit base 532 for fixing the drill bit 531. During radial hole processing, it is necessary to stop rotating the long raw material. The drill bit base 532 provides the drill bit 531 with precise positioning capability in two directions. This allows the device to flexibly adjust the drilling position to adapt to the hole design requirements of different non-standard bolts, thereby enhancing the device's performance in processing irregularly shaped bolts.

[0050] See Figures 9 to 10According to the present invention, a high-precision non-standard screw integrated processing equipment is provided, in which the cutting tool fixing part 512, the thread rolling plate fixing part 522, and the drill bit base 532 share a common lead screw moving assembly 7 in the moving direction parallel to the propulsion mechanism 2. The first support structure 514 and the second support structure 524 are provided with ball bearings 55 on the contact surface with the workpiece. The ball bearings 55 form rolling contact with the long raw material during processing. The shared lead screw moving assembly 7 can save space significantly. The lead screw moving assembly 7 is provided with limiters 71 between each station, allowing only each modular processing device 5 to operate at its own station, thus avoiding collisions.

[0051] See Figures 9 to 10 The high-precision non-standard screw integrated processing equipment provided by this invention also includes an intelligent control system, which can coordinate the control of all motors on the machine base 1. As the control core of the equipment, the intelligent control system can uniformly coordinate the actions of the first drive mechanism 12, the second drive mechanism 13, and the modular processing device 5 motors. According to a preset program, the intelligent control system directs the clamping system to step forward and starts the corresponding processing components at precise times, enabling fully automated operation from long material loading, continuous segmented processing to finished product cutting.

[0052] Implementation process and principle explanation

[0053] The following describes the implementation process of the method of the present invention in detail with a typical processing example. The long raw material has a diameter of 50mm and needs to be processed into a semi-threaded cylindrical head bolt with a cylinder diameter of 49mm, a bolt diameter of 45mm, and a length of 50mm. A 5mm countersunk hole is drilled in the cylindrical part.

[0054] When the equipment is working, the operator first passes a long raw material through the inner hole of the first clamping component 22. The long raw material slides forward on the roller 221 until the front end rests on the second clamping component 33. At this time, the first clamping component 22 clamps the long raw material, the second clamping component 33 is in the clamping state, and the intelligent control system starts the processing program.

[0055] First cycle: The first drive mechanism 12 pushes the long raw material forward until it has reached the required length of a non-standard bolt to be processed. The second clamping assembly 33 clamps the long raw material, the positioning mechanism 4 presses the long raw material against it, and the feed motor of the turning assembly 51 drives the first lead screw 513 to move the cutting tool 511 to the processing position. The drive wheel 31 starts to rotate the long raw material under the action of the motor, and the cutting tool 511 begins to work to complete the outer contour turning of the first bolt segment.

[0056] Second cycle: After turning is completed, the drive wheel 31 stops rotating, the second clamping assembly 33 opens, and the first drive mechanism 12 drives the long material to continue advancing by one bolt length. The second clamping assembly 33 clamps it, and the first bolt segment that has been turned is sent to the thread processing assembly 52 station. The second unprocessed segment of the long material arrives at the turning station. The equipment then operates synchronously: the second lead screw 523 of the thread processing assembly 52 drives the thread rolling plate 521 to radially close, rolling the threads on the rotating first bolt segment. At the same time, the turning assembly 51 begins turning the second bolt segment. Thus, parallel processing at the two stations is achieved.

[0057] The third and subsequent cycles: After a bolt segment completes all the processes of turning, thread rolling, and radial drilling (performed by the radial hole machining component 53), the bolt segment will be sent to the cutting component 54 station. At this time, the positioning mechanism 4 moves away from the long material at a certain distance, and the cutting component 54 actuates to separate the finished bolt from the long material. After the finished bolt is cut off, the positioning mechanism 4 continues to hold the long material, and the cycle continues until a long piece of raw material is processed.

[0058] The machining accuracy of this non-standard bolt on a traditional CNC machine tool is compared as follows:

[0059] 1. For a conventional cantilever CNC machine tool, a 50mm diameter carbon steel shaft is clamped at one end with a chuck. The mechanical model simplifies the support to one end fixed and the other end cantilevered, with a cantilever length L=70mm. The workpiece length is D=50mm, diameter D=45mm, and the cutting tool load is F=1200N. The maximum deflection under the most unfavorable condition is calculated as follows:

[0060] Moment of inertia of circular cross section ≈201687 ;

[0061] Section modulus of bending ≈9008 ;

[0062] The maximum deflection at the end is a= =0.0032mm.

[0063] 2. The present invention also processes the workpiece. One end of a carbon steel optical shaft with a diameter of 50mm is clamped by clamping mechanism 3, and the other end is supported by positioning mechanism. The support of the mechanical model is simplified to one end fixed and the other end hinged. The maximum span of the workpiece that simultaneously accommodates the turning component 51 station, the thread processing component 52 station, and the radial hole processing component 53 station is L2=70+50+50=170mm, the diameter D=45mm, the turning tool load F=1200N, the thread rolling cutter load F=1200N, and the drilling load F=1200N. The maximum deflection under the most unfavorable condition is calculated as follows:

[0064] Moment of inertia of circular cross section ≈201687 ;

[0065] Section modulus of bending ≈9008 ;

[0066] The maximum deflection at mid-span under tool load is =0.00012mm;

[0067] The maximum deflection at mid-span under thread rolling cutter load is =0.00029mm;

[0068] The maximum deflection at mid-span under borehole load is =0.00012mm;

[0069] The cumulative deflection is e = b + c + d = 0.00012 + 0.00029 + 0.00012 = 0.00053 mm.

[0070] In comparison, even under three different load conditions, the cumulative deflection of this invention is much smaller than that of a traditional single-cantilever CNC machine tool, thus enabling high-precision machining.

[0071] The above embodiments detail each technical feature claimed in the claims, its specific role in solving the technical problem, and the beneficial effects it produces. Those skilled in the art can fully implement this invention based on these descriptions.
