Description

TECHNICAL FIELD

[0002] In the manufacturing process of fasteners, the tapping process is a core link for ensuring the thread precision of the inner wall of the sleeve, and the performance of the tapping device directly affects the product quality and production efficiency. The tapping devices on the current market have obvious limitations: most of the devices can only process independent processing tasks of a single sleeve, and the feeding and discharging actions need to be repeatedly completed by manual operation, which not only significantly increases the labor intensity of the operators, but also causes the interruption of the production rhythm, resulting in the difficulty in improving the overall output efficiency. Although some devices introduce a multi-station structure to meet the batch demand, the clamping mechanism is prone to response delay or positioning reference drift when synchronously running, so that the clamping forces of the multiple stations are not uniformly distributed, and stable processing with high precision cannot be achieved, especially in a continuous production scene, such defects will be further amplified, and it is difficult to meet the strict requirements of modern manufacturing on high-batch and high-consistency production. In addition, the traditional locking device generally adopts a single mechanical clamping mode, resulting in uneven distribution of the radial pressure applied to the surface of the sleeve, which is prone to induce slight displacement or periodic shaking of the sleeve during the tapping process. When processing deep hole threads, such vibration phenomena are particularly prominent, which not only accelerates the wear process of the tool edge, but also may cause scratches on the workpiece surface or distortion of the thread profile, ultimately affecting the product qualification rate and shortening the service life of the device.

DETAILED DESCRIPTION

[0019] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the appended spirit and connotation.

[0020] Traditional fastener tapping equipment often faces problems such as low production efficiency, frequent manual loading and unloading, insufficient positioning accuracy of multi-station clamping, and uneven radial pressure distribution of the locking device on the sleeve, leading to offset and shaking. Especially in deep hole threading, vibration exacerbates tool wear and workpiece damage, making it difficult to meet the efficiency and accuracy requirements of high-volume production.

[0021] like Figures 1-8 As shown, the fastener sleeve tapping device of this application embodiment includes a main frame 10. A tapping assembly 20 is provided on one side of the main frame 10, and a material guiding assembly 30 is provided on one side of the main frame 10 along the Y-axis. The main frame 10 and the material guiding assembly 30 are arranged in the same X-axis. The material guiding assembly 30 includes an outer limiting frame 301 integrally formed with the main frame 10. A feeding mechanism 302 is provided inside the outer limiting frame 301. A transmission mechanism 303 located directly below the feeding mechanism 302 is provided on the inner side of the lower end of the main frame 10. A locking mechanism 304 movable in the main frame 10 is provided directly below the transmission mechanism 303. A guarding mechanism 40 located on one side of the transmission mechanism 303 is provided inside the main frame 10.

[0022] The fastener sleeve tapping device of this embodiment can have a main frame 10 with various structural forms. For example, the main frame 10 can be made of welded steel structure, formed by cutting, assembling and welding standard profiles (such as square tubes and channel steel) to create a sturdy load-bearing platform. As another implementation, the main frame 10 can also be integrally formed by casting to achieve higher overall rigidity and vibration damping performance.

[0023] The tapping assembly 20 is located on one side of the main frame 10 and is used to perform tapping operations. Specifically, the tapping assembly 20 can be a manual tapping device, in which the operator drives the tapping tool to perform thread cutting via a handle. Alternatively, the tapping assembly 20 can also be an electric tapping unit, in which a motor drives the tapping tool to rotate and feed, achieving semi-automatic or automatic tapping.

[0024] The guide assembly 30 is responsible for guiding the sleeves to be processed into the processing area. The outer limiting frame 301 in the guide assembly 30 is integrally formed with the main frame 10 and expands outward to form a space for the feeding mechanism 302 to move. The feeding mechanism 302 rotates in the outer limiting frame 301. The two sets of feeding mechanisms 302 rotate synchronously and relative to each other. During the rotation, the sleeves to be processed are fed into the tapping area one by one. The locking mechanism 304 automatically locks the sleeves to be processed that enter the tapping area.

[0025] The guard mechanism 40 can be a lifting and adjusting baffle. When the sleeve arrives at the company area, it separates the processing area from the feeding area to ensure that the debris generated during the tapping process will not fall into the feeding area.

[0026] The fastener sleeve tapping device of this embodiment, through the integrated main frame 10 design and the synergistic effect of the tapping assembly 20, the material guiding assembly 30, and the guarding mechanism 40, achieves automated or semi-automated processing of fastener sleeves. This device effectively solves the shortcomings of traditional tapping equipment in terms of production efficiency, manual loading and unloading, multi-station clamping and positioning accuracy, and locking stability. It helps reduce manual intervention, improves processing efficiency and accuracy, and reduces the risk of sleeve offset and wobbling during the tapping process, thereby improving product quality and equipment operational stability.

[0027] In practice, simple movable locking mechanisms may not provide sufficient stability and cushioning, especially during tapping, when the workpiece needs to be precisely and firmly clamped. At the same time, the potential damage to the workpiece caused by the tapping impact force and the adaptability to workpieces of different sizes must also be considered.

[0028] In this regard, the present application further proposes a locking mechanism 304 including a sliding seat 3041 movably disposed inside the main frame 10, a locking member 3042 rotatably disposed inside the sliding seat 3041, a buffer platform 3043 vertically disposed inside the sliding seat 3041, and the buffer platform 3043 disposed inside multiple sets of locking members 3042, a buffer part 3044 disposed on the bottom wall of the buffer platform 3043, and a driving member 3045 symmetrically disposed on both sides of the buffer platform 3043 inside the sliding seat 3041.

[0029] Specifically, the sliding seat 3041 is the main structure of the locking mechanism 304, and it is designed to move inside the main frame 10. This mobility allows the locking mechanism 304 to be positioned according to the size of the workpiece or processing requirements, thereby accommodating fastener sleeves of different sizes. The sliding seat 3041 is typically made of high-strength material to ensure sufficient rigidity and stability during locking and tapping processes.

[0030] The locking element 3042 is rotatably disposed inside the sliding seat 3041. Its main function is to contact the workpiece and apply clamping force to securely fix the workpiece in a predetermined position. Due to its rotatable arrangement, the locking element 3042 can be easily adjusted in angle or position to adapt to the shape of the workpiece or to provide more uniform pressure during clamping. The locking element 3042 can be designed as a jaw, roller, or eccentric wheel with a specific shape, achieving rapid clamping and release of the workpiece through rotational action. In some embodiments, multiple sets of locking elements 3042 can be provided to provide encircling clamping of the workpiece from multiple directions.

[0031] The buffer platform 3043 is vertically mounted inside the sliding seat 3041, and its position is designed to be inside multiple sets of locking elements 3042. This means that the buffer platform 3043 is located in the area surrounded by the locking elements 3042, and is used to directly support the bottom of the workpiece.

[0032] The buffer section 3044 is located on the bottom wall of the buffer table 3043. Its core function is to provide an upward thrust to push the workpiece out for easy unloading when resetting is required after tapping. The buffer section 3044 can be made of elastic materials, such as rubber pads or polyurethane pads, or can be implemented using springs, hydraulic dampers, or other structures. The selection of its material and structure should be based on the expected ejection height.

[0033] The drive components 3045 are symmetrically arranged on both sides of the buffer table 3043. Their main function is to drive the buffer table 3043 to move up and down, and may also assist the locking component 3042 in clamping the workpiece. The symmetrical arrangement ensures the smoothness and stability of the buffer table 3043 during the lifting process, avoiding tilting or jamming. The drive components 3045 can include various forms such as cylinders, hydraulic cylinders, stepper motors with lead screws, etc. By precisely controlling their movements, flexible support and positioning of the workpiece can be achieved.

[0034] In some embodiments of this application, the locking mechanism 304 includes a sliding seat 3041, a locking member 3042 rotatably disposed on its inner side, and a buffer platform 3043 vertically disposed. However, the locking member 3042, which is only rotatably disposed, has an unclear specific locking structure and operating mode, which may make it difficult to ensure the effective transmission of force and the stability of locking when locking the buffer platform 3043, thereby affecting the positioning accuracy of the workpiece in subsequent processing.

[0035] In this regard, this application further proposes a specific structure for the locking member 3042, which includes a rotating rod 30421 rotatably disposed inside the sliding seat 3041, a contact part 30422 on one side of the rotating rod 30421 that fits against the outer surface of the buffer table 3043, and a pressing block 30423 at the other end of the rotating rod 30421.

[0036] Specifically, the rotating rod 30421 is the core rotating component of the locking element 3042. It typically has a rod-like or shaft-like structure and can rotate around its own axis. The rotating rod 30421 is rotatably mounted inside the sliding seat 3041, serving as the carrier for the rotational movement of the locking element 3042. Its rotational motion is crucial for locking or unlocking the buffer platform 3043. The rotating rod 30421 can be made of high-strength metal to withstand the stress generated during locking. The contact portion 30422 is a structure on the rotating rod 30421 that directly contacts the outer surface of the buffer platform 3043. This contact portion 30422 can be designed in various shapes, such as a protrusion, an eccentric wheel, an arc surface, or a flat surface, to ensure a tight fit with the outer surface of the buffer platform 3043 when the rotating rod 30421 rotates. By engaging the contact part 30422 with the buffer table 3043, the rotating rod 30421 can be rotated during the lifting and lowering of the buffer table 3043, thereby effectively fixing the sleeve to be processed on the buffer table 3043. The clamping block 30423 is located at the other end of the rotating rod 30421, opposite the contact part 30422. This clamping block 30423 can serve as a force application point for operating the locking member 3042. When the buffer table 3043 moves downward, it engages with the contact part 30422, thereby driving the rotating rod 30421 to rotate. Furthermore, the clamping block 30423 can also serve as part of the lever arm. Through its size and shape design, the mechanical properties of the locking member 3042 are optimized, ensuring sufficient locking force is generated even with a small operating force to reinforce the sleeve to be tapped.

[0037] Through the above technical solution, this application clarifies the specific structure and working method of the locking component 3042. When it is necessary to lock the workpiece to be processed on the buffer platform 3043, the operation of the drive component 3045 pushes the buffer platform 3043 to move up and down. During the up and down movement of the buffer platform 3043, it comes into contact with the contact part 30422, which drives the rotating rod 30421 to rotate. As the rotating rod 30421 rotates, the contact part 30422 on one side will tightly adhere to and press against the outer surface of the buffer platform 3043, thereby driving the rotating rod 30421 to rotate when the buffer platform 3043 moves up and down. The pressing block 30423 then abuts against the outer surface of the sleeve to be processed to fix the sleeve. This structural design makes the locking action more direct and reliable, avoiding the problem of unstable locking caused by structural ambiguity.

[0038] This application further proposes that the drive unit 3045 includes a drive part 30451 disposed inside the slide seat 3041, and the output end of the drive part 30451 is connected to a top block 30452 that matches the buffer stage 3043.

[0039] Specifically, the drive unit 30451 is the core component used to generate driving force or drive motion, and its function is to precisely control the lifting and lowering of the buffer platform 3043. The drive unit 30451 can be implemented in various forms. For example, it can be a servo motor or a stepper motor, which converts rotary motion into linear motion through a reduction mechanism and a lead screw and nut mechanism, thereby driving the lifting and lowering of the buffer platform 3043; it can also be a hydraulic cylinder or a pneumatic cylinder, which drives the piston rod to extend and retract through fluid pressure to achieve the vertical displacement of the buffer platform 3043.

[0040] The top block 30452 is a connector between the drive unit 30451 and the buffer platform 3043. Its function is to smoothly and effectively transmit the driving force or motion generated by the drive unit 30451 to the buffer platform 3043. The design of the top block 30452 needs to match the force-bearing surface or connecting structure of the buffer platform 3043 to ensure a tight fit and prevent swaying, uneven loading, or separation during lifting. For example, the top block 30452 can be designed to match a specific structure (such as a plane, protrusion, or groove) on the outer surface of the buffer platform 3043 to achieve stable contact and efficient force transmission. This matching design helps improve the stability and accuracy of the lifting of the buffer platform 3043.

[0041] By using the above technical solution, the drive unit 30451 is set as the drive source, and its output end is connected to the top block 30452 that matches the buffer table 3043, which enables precise and stable lifting control of the buffer table 3043. The matching design between the top block 30452 and the buffer table 3043 ensures that the driving force can be transmitted efficiently and smoothly, avoiding shaking or jamming during the driving process, thereby improving the stability of the locking mechanism 304 in clamping the sleeve to be tapped.

[0042] This application further proposes that the buffer platform 3043 includes a limiting platform 30431 that is vertically disposed inside the sliding seat 3041, and the outer surface of the limiting platform 30431 is symmetrically provided with an inner groove 30432 that matches the top block 30452.

[0043] The limiting platform 30431 is the main body of the buffer platform 3043. It is designed to move vertically up and down inside the sliding seat 3041. The main function of the limiting platform 30431 is to support and position the fastener sleeve to be processed, ensuring that it is in the correct position when the locking mechanism 304 is operating. The inner groove 30432 is a recessed structure provided on the outer surface of the limiting platform 30431. Its shape, size and position match the top block 30452 of the driving member 3045. When the top block 30452 and the inner groove 30432 cooperate, they can form a guiding and limiting function to ensure that the limiting platform 30431 will not shift laterally or tilt during the lifting process.

[0044] This application further proposes an improved solution for the feeding mechanism 302, which includes a rotating roller 3021 rotatably disposed inside the outer limit frame 301, and protrusions 3022 disposed on the outer surface of the rotating roller 3021 and arranged in a ring array.

[0045] Specifically, the rotary roller 3021 is the core component of the feeding mechanism 302. It is designed as a rotatable cylinder and is typically driven by a drive unit (such as a motor and a reducer). The rotational motion of the rotary roller 3021 provides power for the conveying of the fastener sleeves, which are fed out one by one or in sequence from the hopper inside the outer limit frame 301 through contact and friction with the fastener sleeves.

[0046] The protrusions 3022 are protruding structures provided on the outer surface of the rotating roller 3021, and are evenly distributed in a ring array. The main function of these protrusions 3022 is to effectively engage or hold the fastener sleeves, thereby stably gripping and pushing the fastener sleeves forward when the rotating roller 3021 rotates, preventing them from slipping or stacking on the roller surface. The protrusions 3022 can have various shapes, such as cylindrical, conical, prismatic, or grooves of a specific shape. Their size and spacing are optimized according to the outer dimensions of the fastener sleeves to ensure that only one or a specific number of fastener sleeves are fed at a time, achieving precise feeding.

[0047] This application further proposes that the transmission mechanism 303 includes a support frame 3031 disposed on the main frame 10, a receiving frame 3032 rotatably disposed at one end of the support frame 3031 away from the main frame 10, and a baffle plate 3033 disposed on one side of the receiving frame 3032.

[0048] Specifically, the support frame 3031 is mounted on the main frame 10, and its main function is to provide stable structural support for the transmission mechanism 303 and to support the receiving rack 3032. The support frame 3031 can be made of high-strength metal materials (such as steel or aluminum alloy) to ensure sufficient rigidity and load-bearing capacity, thereby ensuring the stability and reliability of the entire transmission mechanism 303 during operation. The support frame 3031 can be securely connected to the corresponding position of the main frame 10 by welding, bolting, or other fixing methods.

[0049] The receiving rack 3032 is rotatably mounted at one end of the support frame 3031 opposite to the main frame 10. The receiving rack 3032 is a key component for receiving workpieces from the feeding mechanism 302 and guiding them to the locking mechanism 304. Because the receiving rack 3032 has a rotating function, it can flip or swing at specific times, thereby achieving precise placement of the workpiece or facilitating cleaning. The surface of the receiving rack 3032 can be designed as a smooth plane or equipped with guide grooves that match the shape of the workpiece to reduce frictional resistance during transport and prevent jamming. The rotation of the receiving rack 3032 can be achieved through a motor-driven rotating shaft mechanism. The main function of the baffle plate 3033 is to prevent the workpiece from deviating from the predetermined transport path when it slides or rolls on the receiving rack 3032, ensuring that the workpiece can remain stably on the receiving rack 3032 and ultimately fall accurately into the receiving position of the locking mechanism 304.

[0050] This application further proposes that a limiting block 101 for limiting the movement of the locking mechanism 304 is provided at the bottom inner side of the main frame 10, and a pushing mechanism 102 is provided at the bottom inner side of the main frame 10. The pushing mechanism 102 includes a conveyor belt 1021 rotatably disposed inside the main frame 10, and multiple sets of pushing plates 1022 are arrayed on the conveyor belt 1021.

[0051] The limiting block 101 is a physical limiting structure located at the bottom inner side of the main frame 10. Its main function is to provide a precise endpoint or range limit for the movement of the locking mechanism 304. The pushing mechanism 102 is a device used to push the processed or unprocessed workpiece (e.g., fastener sleeve) or the locking mechanism 304 itself from a specific position to the next workstation or discharge area. Its core function is to realize the automated and continuous movement of the workpiece or mechanism, thereby improving the overall operating efficiency and automation level of the equipment. The pushing mechanism 102 can adopt various driving methods, such as motor drive or cylinder drive, to provide a stable pushing force, depending on actual needs.

[0052] The pusher plates 1022 are raised structures arrayed on the outer surface of the conveyor belt 1021. These pusher plates 1022 directly contact the locking mechanism 304 being pushed, and through the movement of the conveyor belt 1021, push the workpiece or mechanism in a predetermined direction. The shape, size, and spacing of the pusher plates 1022 can be optimized according to the characteristics of the workpiece being processed and the pushing requirements to ensure stable gripping and efficient pushing.

[0053] This application further proposes an improved scheme for the guardrail mechanism 40. The guardrail mechanism 40 includes a baffle 401 disposed inside the main frame 10, a connecting plate 402 provided at one end of the baffle 401 extending to the outside of the main frame 10, a driven part 403 provided on the connecting plate 402, and a transmission part 404 matched with the driven part 403 provided on the main frame 10.

[0054] The barrier mechanism 40 includes a baffle 401 disposed inside the main frame 10. The baffle 401 acts as a physical barrier, mainly used to isolate the working area inside the equipment, prevent foreign objects from entering, or protect operators from injury from internal moving parts. The baffle 401 can be made of materials such as metal plates or high-strength plastic plates, and its size and shape can be designed according to actual protection requirements. For example, it can be designed as a structure that can be translated, rotated, or flipped.

[0055] A connecting plate 402 is provided at one end of the baffle 401 extending to the outer side of the main frame 10. The function of the connecting plate 402 is to connect the baffle 401 to an external drive or operating mechanism, thereby realizing the control of the baffle 401. The connecting plate 402 is provided with a driven part 403, which is a component that receives external driving force. Its design should match the transmission part 404 to ensure reliable transmission. The driven part 403 can take various forms, such as a rack, a slider, or a driven element in a linkage mechanism, and its selection depends on the required motion mode (such as translation or rotation) and transmission efficiency. The main frame 10 is provided with a transmission part 404 that matches the driven part 403. The transmission part 404 is a component that provides driving force to drive the driven part 403, thereby driving the connecting plate 402 and the baffle 401 to perform a preset motion. The transmission unit 404 may include a drive source such as a motor, cylinder, or hydraulic cylinder, and cooperate with a transmission mechanism such as a gear, lead screw, or cam to achieve precise control of the baffle 401. For example, the motor drives the gear to mesh with the rack of the driven unit 403 to achieve the reciprocating movement of the baffle 401.

[0056] This application further proposes that the driven part 403 includes a base plate 4031 detachably disposed on one side of the connecting plate 402, and the base plate 4031 has a toothed groove 4032 that meshes with the transmission part 404.

[0057] The base plate 4031 is the core component constituting the driven part 403. It is designed to be detachably mounted on one side of the connecting plate 402, meaning it can be reversibly connected to the connecting plate 402 rather than permanently. Specifically, the base plate 4031 can be connected to the connecting plate 402 by various means such as bolts, clips, pins, or sliding grooves. A toothed groove 4032 is formed on the base plate 4031 to mesh with the transmission part 404. The toothed groove 4032 is a groove with a specific tooth structure formed on the base plate 4031, used for mechanical meshing with the corresponding tooth structure on the transmission part 404, thereby realizing the transmission of power or motion. Specifically, if the transmission part 404 is a gear, the toothed groove 4032 can be designed as a rack or arc-shaped toothed groove matching the tooth profile of the gear. When the transmission part 404 (e.g., a gear) rotates, the toothed groove 4032 drives the base plate 4031 to perform linear or rotational motion, thereby driving the guarding mechanism 40 to perform corresponding actions. This meshing connection method ensures transmission accuracy and load-bearing capacity.

[0058] This equipment provides a solution: First, the fastener sleeve is placed at the inlet of the guide assembly 30. The outer limiting frame 301 of the guide assembly 30 is integrally formed into the main frame 10, providing a stable guide path for the sleeve. The rotating roller 3021 in the feeding mechanism 302 rotates inside the outer limiting frame 301, and the annular array of protrusions 3022 on its outer surface can accurately separate individual sleeves from the material pile and push them forward. Unlike traditional equipment that requires frequent manual loading and unloading, this automatic feeding method significantly improves production efficiency and reduces manual intervention.

[0059] The pushed sleeve then enters the transmission mechanism 303, which includes a support frame 3031 mounted on the main frame 10, with a receiving frame 3032 rotatably mounted at one end opposite to the main frame 10. After receiving the sleeve, the receiving frame 3032 performs initial positioning via a baffle plate 3033 on one side and rotates to accurately deliver the sleeve to the tapping position, i.e., directly above the locking mechanism 304.

[0060] At this time, the locking mechanism 304 operates, and the sleeve to be processed falls into the sliding seat 3041 on the locking mechanism 304. The sliding seat 3041 receives the sleeve, and then the driving unit 30451 pushes the top block 30452 to match the buffer table 3043. The top block 30452 then enters the inner groove 30432, and the buffer table 3043 moves down. When the buffer table 3043 moves down, it abuts against the connecting contact part 30422, causing the rotating rod 30421 to rotate, and the pressing block 30423 presses against the surface of the sleeve to be processed, fixing the sleeve. This achieves uniform radial support and stable positioning of the sleeve, effectively avoiding offset or shaking during the tapping process. Especially when processing deep hole threads, it can significantly reduce vibration, reduce tool wear and workpiece damage, and ensure the machining accuracy of the thread.

[0061] After the sleeve is securely clamped, the locking mechanism 304 moves inside the main frame 10 to the tapping position. The tapping assembly 20 on one side of the main frame 10 is activated to tap the sleeve. Before the tapping operation, when the sleeve moves to the tapping position, the transmission part 404 rotates and engages with the driven part 403, which drives the baffle 401 to rise and fall and move downward to intercept the feeding area, preventing chip ejection during subsequent tapping.

[0062] In summary, the fastener sleeve tapping device of this application effectively solves the shortcomings of traditional tapping devices in terms of production efficiency, manual loading and unloading, multi-station clamping and positioning accuracy, and locking stability. It helps to reduce manual intervention, improve processing efficiency and accuracy, and reduce the risk of sleeve deviation and shaking during the tapping process, thereby improving product quality and equipment operation stability.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
