Description

Technical Field

[0001] This utility model relates to the technical field of metal processing equipment, specifically to an automated thread rolling device for rearview mirror brackets. Background Technology

[0002] In the rapid development of the automotive industry, rearview mirrors, as a core component ensuring driving safety, have seen continuous improvement in their functional integration and assembly reliability. With the widespread adoption of intelligent systems such as lane departure warning and rain sensors in high-end models, rearview mirror brackets not only need to support and fix the mirror body but also need to achieve stable assembly with components such as plastic covers and vehicle body bases through threaded connections. As a key interface for bracket assembly, the machining accuracy of the threaded structure directly affects the connection strength and safety of use. Insufficient thread size consistency or surface quality defects can easily lead to risks such as loosening or detachment. Therefore, stringent requirements are placed on the adaptability and precision of thread processing equipment. Thread rolling machines are commonly used industrial equipment for machining external threads on shafts. Modern thread rolling machines typically consist of a spindle system, a feed system, a cooling system, and a control system. They achieve thread forming by pressing the workpiece with two opposing rollers. The thread rolling rollers include a stationary roller and a moving roller. The stationary roller is immovable, while the moving roller, driven by hydraulic pressure, can move closer to or away from the stationary roller. The two rollers rotate via a reducer. When the moving roller moves away from the stationary roller, the workpiece can be placed between the two rollers. Then, the moving roller moves closer to the stationary roller, pressing the workpiece to form the thread. This machining method, due to its advantages of high efficiency, chip-free operation, and controllable precision, has become the mainstream technology for thread forming of metal parts. For example, the existing technology "Automatic Loading and Unloading Device for Thread Rolling Machines" (Publication No.: CN109500325A) uses a combination of multiple cylinders and push rods to automatically load and push parts, reducing operator workload and improving processing efficiency. However, this existing technology has the following technical problems: 1. High maintenance difficulty, low efficiency, and high cost. Existing thread rolling equipment uses a feeding conveyor structure that runs through the thread rolling machine. After the thread rolling operation is completed, a pusher cylinder drives a top rod to push a new workpiece into the thread rolling machine, while the already processed workpiece is pushed onto the feeding conveyor at the machine's outlet. However, due to the complex structure of the thread rolling machine, if the feeding conveyor belt runs through the machine, it must avoid the machine's components and pass through the gaps between them. When maintenance is required on the conveyor belt and the thread rolling machine, operators cannot directly access the faulty parts; they must first disassemble the machine's outer casing, protective plates, and even some core components. This significantly increases the difficulty of equipment maintenance, reduces efficiency, and easily damages precision components during disassembly, increasing maintenance costs.

[0003] 2. Poor processing quality and safety hazards. In existing technologies, the conveyor belt runs through the entire thread rolling machine. This increases the risk of interference between the conveyor and the machine's components. The gap between the conveyor belt and the internal components is extremely small, and the conveyor belt is constantly in motion. Firstly, if the conveyor belt shifts due to wear, it can easily collide with the machine's components, causing the belt to break or, in severe cases, damaging core components such as the thread rolling wheel and feed screw, leading to equipment downtime and safety accidents. Secondly, existing technologies rely on simultaneously pushing new workpieces into the thread rolling machine and pushing pre-processed workpieces out. Without a guiding and positioning device, workpieces are prone to shifting and loosening during processing, resulting in substandard thread quality. Furthermore, the current thread rolling equipment's feeding method involves pushing new workpieces into the machine while simultaneously pushing pre-processed workpieces out. If the pre-processed workpiece shifts position, it can easily become jammed during ejection, causing collisions and damaging both the workpieces and the equipment, leading to safety issues. Utility Model Content

[0004] This utility model provides an automated thread rolling device for rearview mirror brackets, which can solve the problems of existing thread rolling devices lacking a guiding and positioning device for the workpiece during thread processing, making it easy for the workpiece to shift and loosen during processing, resulting in a decrease in thread processing quality; and the problem that during the workpiece loading and unloading process, the position of the already processed workpiece is easily shifted and loosened, causing jamming and preventing it from exiting the processing area of ​​the thread rolling machine in time, resulting in the collision between the new workpiece and the already processed workpiece during loading, causing workpiece wear and equipment safety hazards.

[0005] This application provides the following technical solution: an automated thread rolling device for a rearview mirror bracket, comprising a frame and thread rolling wheels, a feeding section, a discharging section, and a guide support assembly mounted on the frame; the thread rolling wheels include stationary wheels and moving wheels; the feeding section is used to feed the workpiece into the guide support assembly; The guide support assembly is located between the thread rolling wheel and the feeding part. The guide support assembly includes a support plate fixed on the frame and a positioning sleeve rotatably connected to the support plate. The positioning sleeve is provided with a guide hole, which is a stepped hole. The guide hole is directly opposite the stationary wheel and the moving wheel of the thread rolling wheel. The positioning sleeve is used to position and support the workpiece during thread rolling, and the guide hole is used to guide the workpiece when it enters or exits the positioning sleeve.

[0006] Beneficial effects: 1. Precise positioning ensures machining accuracy and solves thread quality defects caused by workpiece misalignment. Existing thread rolling equipment lacks a dedicated guiding and positioning device, leading to workpiece misalignment and loosening during machining, resulting in degraded thread quality. This equipment achieves guiding and positioning functions through a guide support assembly. The positioning sleeve is fixed to the support plate, and its internal stepped guide hole aligns with the stationary and moving wheels of the thread rolling wheel. When the workpiece passes through the positioning sleeve during machining, it directly limits the radial misalignment of the workpiece, preventing workpiece wobbling caused by the radial force generated when the thread rolling wheel squeezes the workpiece. Furthermore, the stepped guide hole provides axial restraint at the step of the workpiece, preventing it from passing through the positioning sleeve and ensuring the accuracy and quality of thread machining. 2. Stable guidance avoids collisions during loading and unloading, eliminating workpiece wear and equipment safety risks. Addressing the issue of existing equipment causing pre-processed workpieces to shift and loosen during loading and unloading, leading to collisions between new and pre-processed workpieces, this equipment's guide support assembly guides and constrains the workpiece loading and unloading process. The guide holes within the positioning sleeve guide the workpiece's rod during loading and unloading, ensuring smooth exit of pre-processed workpieces without jamming. This further prevents collisions between new and pre-processed workpieces, effectively improving safety. During loading, the positioning holes also guide the workpiece smoothly into the positioning sleeve, ensuring precise alignment with the thread rolling wheel and improving processing quality. Furthermore, the unloading section includes an unloading assembly, a conveyor belt, and an unloading plate, all sequentially fixed to the frame along a straight line; the unloading assembly is located in the direction of the thread rolling wheel; the unloading assembly includes a bracket fixed to the frame, an unloading cylinder fixed to the bracket, an unloading rod slidably connected to the bracket, and a connecting rod fixedly connected between the piston rod of the unloading cylinder and the unloading rod; the end of the unloading rod away from the connecting rod is directly opposite the positioning hole of the positioning sleeve, and the diameter of the unloading rod is smaller than the diameter of the positioning hole; the unloading rod is used to push the pre-processed workpiece inside the positioning sleeve onto the conveyor belt; the positioning sleeve is located between the thread rolling wheel and the transmission belt.

[0007] Beneficial effects: Existing technologies often employ a through-type feeding conveyor located beneath the thread rolling machine, requiring disassembly of the outer casing, protective plates, and even core components for maintenance, resulting in cumbersome operations. This new equipment adopts a separate, external layout for the feeding section, consisting of the discharge assembly, conveyor belt, and feeding plate. The support for the discharge assembly, the conveyor belt, and the feeding plate are all independently fixed to the frame surface, with the positioning sleeve located between the thread rolling wheel and the conveyor belt. No structure penetrates the interior of the thread rolling machine. When maintenance is required, operators can directly access the discharge assembly and conveyor belt components without disassembling the thread rolling machine itself, completely avoiding the problem of insufficient maintenance space caused by obstructed components and significantly reducing the difficulty of maintenance operations.

[0008] Furthermore, the feeding section includes a feeding assembly and a receiving assembly disposed next to the feeding assembly. The feeding assembly is used to feed the workpiece onto the receiving assembly, and the receiving assembly is used to feed the workpiece into the support assembly.

[0009] Beneficial effects: The feeding component can focus on the orderly conveying of batch workpieces, such as feeding materials from the hopper to the receiving component; the receiving component, as an intermediate transition link, can accurately receive the workpieces sent by the feeding component, and perform secondary calibration according to the position of the guide hole of the positioning sleeve of the support component to ensure that the workpieces are smoothly fed into the guide support component in the correct posture. By realizing automated feeding, processing efficiency is improved.

[0010] Furthermore, the feeding assembly includes a material platform, a drive unit, an inclined platform, and a stop unit fixed on the frame. The drive unit is located between the material platform and the inclined platform. The drive unit includes a drive cylinder fixed on the frame and a top block fixed to the end of the piston rod of the drive cylinder. The top surfaces of the top block, the inclined platform, and the material platform are all inclined surfaces with the same slope. The top block is used to feed the workpiece on the material platform onto the inclined platform under the drive of the drive cylinder.

[0011] Beneficial effects: The top surfaces of the material platform, top block, and inclined table have the same inclination, so when the drive cylinder drives the top block to push the workpiece, the top block can send the workpiece on the material platform to the inclined table under the drive of the drive cylinder, thereby realizing automated feeding. The workpiece can slide smoothly along the continuous inclined surface, improving the stability and efficiency of feeding.

[0012] Furthermore, the stop part includes drive rods pivotally connected to both sides of the top block, drive plates pivotally connected to the ends of the drive rods, uprights fixed to both sides of the inclined platform, a rotating shaft rotatably connected between the uprights, and a baffle fixed to the shaft. The end of the drive plate away from the drive rod is fixed to the end of the rotating shaft. The baffle is used to limit the workpiece sliding down the inclined platform.

[0013] Beneficial effects: When the drive cylinder pushes the top block upwards to push the workpiece, the drive rods on both sides of the top block simultaneously lift one end of the drive plate, thereby driving the rotating shaft between the uprights to rotate. This causes the upright baffle to automatically swing down, preventing the workpiece fed onto the inclined platform from sliding down the platform. When the drive cylinder returns to its original position, the top block drives the drive rods back, and the rotating shaft rotates in the opposite direction under mechanical linkage. The baffle no longer limits the workpiece, and the workpiece can roll along the inclined platform into the receiving assembly. Compared with existing technologies, the baffle does not require an additional power source to control the blocking action. This automated blocking mechanism linked to the feeding and pushing process ensures that only one workpiece is fed at a time, avoiding feeding jams caused by multiple stacks. It also eliminates the need for a separate blocking drive component, simplifying the structure and reducing the risk of failure. Furthermore, it adapts to the rhythm of inclined conveying, ensuring the rearview mirror bracket workpiece has a stable posture and orderly conveying during the feeding process, improving feeding accuracy and efficiency.

[0014] Furthermore, the receiving assembly includes a vertical plate fixed on the frame, a receiving cylinder fixed on the vertical plate, a receiving arm fixed to the end of the piston rod of the receiving cylinder, a receiving block fixed on the receiving arm, and a pushing cylinder fixed to the end of the receiving block. The receiving block is provided with a V-shaped groove above it and is located above the conveyor belt. The inclined platform is set close to the receiving block.

[0015] Beneficial effects: The receiving cylinder can drive the receiving arm to flexibly adjust the position of the receiving block, enabling it to accurately receive workpieces conveyed by the inclined platform; the V-groove of the receiving block can adapt to the shaft structure of the rearview mirror bracket, providing stable positioning for the workpiece and preventing it from rolling away due to inertia during transfer, ensuring that the workpiece always maintains the correct posture. Simultaneously, the layout of the receiving block above the conveyor belt avoids spatial interference with the unloading section and reserves a reasonable path for subsequently sending the workpiece into the guide support assembly. The overall structure is compact and flexible, improving the stability and accuracy of the loading connection, ensuring the smoothness of the automated loading process, and achieving precise connection between the loading and receiving components.

[0020] Figure 5 for Figure 4 A schematic diagram of the middle block resetting. Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method: The markings in the accompanying drawings include: frame 1, thread rolling machine 2, connecting rod 3, discharge rod 31, bracket 4, discharge cylinder 5, thread rolling wheel 6, support plate 7, positioning sleeve 8, upright plate 9, receiving cylinder 10, receiving block 11, receiving arm 111, mounting block 12, pushing cylinder 13, conveyor belt 14, unloading plate 15, unloading box 16, material platform 17, inclined platform 18, baffle 19, upright 20, rotating shaft 21, drive plate 22, drive rod 23, top block 24, drive cylinder 25, workpiece 26.

[0022] Example 1 like Figures 1 to 5As shown, an automated thread rolling device for a rearview mirror bracket 4 includes a frame 1 and thread rolling wheels 6, a feeding section, a discharging section, and a guide support assembly mounted on the frame 1. The thread rolling wheels 6 are mounted on a thread rolling machine 2 and include a stationary wheel and a moving wheel. Both the thread rolling machine 2 and the thread rolling wheels 6 are existing technologies, and their structures will not be described in detail here.

[0023] like Figure 1 and Figure 2 As shown, the unloading section includes an unloading assembly, a conveyor belt 14, and an unloading plate 15, which are fixed sequentially on the frame 1 along the same straight line. The tail end of the unloading plate 15 is provided with an unloading box 16 for collecting the processed workpieces 26. The unloading assembly is located in the direction of the thread rolling wheel 6. The unloading assembly includes a bracket 4 fixed on the frame 1, an unloading cylinder 5 fixed on the bracket 4, an unloading rod 31 slidably connected on the bracket 4, and a connecting rod 3 fixedly connected between the piston rod of the unloading cylinder 5 and the unloading rod 31. The piston rod of the unloading cylinder 5 moves to drive the connecting rod 3, thereby driving the unloading rod 31 to slide axially on the bracket 4.

[0024] The guide support assembly is located between the thread rolling wheel 6 and the feeding section. The guide support assembly includes a support plate 7 fixed to the frame 1 and a positioning sleeve 8 rotatably connected to the support plate 7. The positioning sleeve 8 is located between the thread rolling wheel 6 and the transmission belt. The positioning sleeve 8 has a guide hole, which is a stepped hole. When the workpiece 26 is inserted into the positioning sleeve 8, the stepped hole corresponds to the stepped structure on the workpiece 26, preventing the workpiece 26 from passing through the positioning sleeve 8. The guide hole is directly opposite the stationary and moving wheels of the thread rolling wheel 6. A bearing is installed on the support plate 7, and the positioning sleeve 8 is fixed to the inner ring of the bearing. This allows the positioning sleeve 8 to rotate with the workpiece 26 when it is inserted into the positioning sleeve 8 and rotates under the pressure of the thread rolling wheel 6, thereby reducing friction between the inner wall of the positioning hole and the workpiece 26. The end of the discharge rod 31 away from the connecting rod 3 is directly opposite the positioning hole of the positioning sleeve 8, and the diameter of the discharge rod 31 is smaller than the diameter of the positioning hole, so that the discharge rod 31 can extend into the positioning hole a certain distance, thereby pushing the workpiece 26 that has been processed in the positioning sleeve 8 onto the conveyor belt 14 through the axial sliding of the discharge rod 31.

[0025] like Figures 3 to 4 As shown, the feeding part includes a feeding component and a receiving component disposed next to the feeding component. The feeding component is used to feed the workpiece 26 onto the receiving component, and the receiving component is used to feed the workpiece 26 into the positioning sleeve 8 of the support component.

[0026] like Figures 2 to 4As shown, the receiving assembly includes a vertical plate 9 fixed on the frame 1, a receiving cylinder 10 fixed on the vertical plate 9, a receiving arm 111 fixed to the end of the piston rod of the receiving cylinder 10, a receiving block 11 fixed on the receiving arm 111, and a pushing cylinder 13 fixed to the end of the receiving block 11. A V-shaped groove is provided above the receiving block 11, and the receiving block 11 is located above the conveyor belt 14. like Figures 3 to 5 As shown, the feeding assembly includes a material platform 17 fixed on the frame 1, a drive unit, an inclined platform 18, and a stop unit, with the drive unit located between the material platform 17 and the inclined platform 18; Figure 4 As shown, the drive unit includes a drive cylinder 25 fixed to the frame 1 and a top block 24 fixed to the piston rod end of the drive cylinder 25. The top surfaces of the top block 24, the inclined platform 18, and the material table 17 are all inclined surfaces with the same slope. The top block 24 is used to feed the workpiece 26 on the top of the material table 17 into the inclined surface of the inclined platform 18 under the drive of the drive cylinder 25. The inclined platform 18 is located close to the receiving block 11, which helps the workpiece 26 to roll into the V-groove on the receiving block 11. The blocking unit includes drive rods 23 pivotally connected to both sides of the top block 24, a drive plate 22 pivotally connected to the end of the drive rods 23, uprights 20 fixed to both sides of the inclined platform 18, a rotating shaft 21 rotatably connected between the uprights 20, and a baffle 19 fixed to the rod of the rotating shaft 21. The end of the drive plate 22 away from the drive rod 23 is fixed to the end of the rotating shaft 21. The usage method of this device is as follows: When using this equipment, the workpieces 26 to be processed are first placed in batches onto the inclined surface of the material platform 17 of the feeding assembly. Figure 4 As shown, the drive cylinder 25 drives the top block 24 to push a workpiece 26 upward. After reaching the highest point, the workpiece 26 rolls down onto the inclined platform 18. When the top block 24 pushes upward, the drive rods 23 on both sides of the top block 24 simultaneously push the drive plate 22. The rotation of the drive plate 22 drives the rotating shaft 21 between the uprights 20 to rotate, causing the baffle 19 to swing down, thereby limiting the workpiece 26 on the inclined platform 18. Then, the top block 24 moves down to reset. Figure 5 In the state shown, the baffle 19 swings upward, and the single workpiece 26 on the inclined platform 18 slides down the inclined platform 18 into the V-groove of the receiving block 11 of the receiving assembly; after the top block 24 is reset, the next workpiece 26 will roll down the inclined surface of the platform 17 onto the inclined surface at the top of the top block 24 to be ready for the next lifting and conveying.

[0027] like Figure 3 As shown, the workpiece 26 entering the receiving block 11 falls into the V-groove. The receiving cylinder 10 moves downward, causing the receiving block 11 to move downward, aligning the workpiece 26 in the V-groove with the positioning hole of the positioning sleeve 8, and then... Figure 2Driven by the piston rod of the pusher cylinder 13, the workpiece 26 enters the positioning hole of the positioning sleeve 8 from the receiving block 11, so that the part of the workpiece 26 to be processed extends between the stationary wheel and the moving wheel of the thread rolling wheel 6. Then the thread rolling machine 2 starts, the moving wheel moves closer to the stationary wheel and squeezes the workpiece 26. The workpiece 26 rotates under the action of the thread rolling wheel 6, and the positioning sleeve 8 rotates synchronously with the workpiece 26 to reduce friction and realize thread processing. At the same time, the receiving cylinder 10 moves upward to drive the receiving block 11 back to its original position to pick up the next workpiece 26 rolling off the inclined table 18, so as to realize continuous processing.

[0028] After the thread rolling wheel 6 finishes machining the threads of the workpiece 26, the discharge cylinder 5 of the discharge assembly drives the connecting rod 3 and the discharge rod 31 to slide. The discharge rod 31 extends into the guide hole of the positioning sleeve 8, pushing the machined workpiece 26 out and onto the conveyor belt 14. At this time, the receiving block 11, which has moved upwards, is far away from the upper surface of the conveyor belt 14, thus preventing interference between the workpiece 26 and the receiving block 11 when it falls onto the conveyor belt 14. The conveyor belt 14 continues to transport the workpiece 26 to the unloading plate 15. Finally, the workpiece 26 slides into the unloading box 16 for collection, thus completing a single processing cycle. The equipment can repeat the above steps to achieve automated batch processing.

[0029] The above are merely embodiments of this utility model, and the utility model is not limited to the field covered by this embodiment. Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
