Description

Technical Field

[0001] This invention relates to the field of thread rolling equipment technology, specifically a thread rolling machine with an automatic feeding and positioning mechanism. Background Technology

[0002] Thread rolling machines are specialized equipment used for thread processing of round bar workpieces, and are widely used in fasteners, mechanical parts, hardware processing and other industries. Currently, the feeding structure of conventional thread rolling machines on the market is relatively simple, and most rely on manual feeding and alignment. A few semi-automatic thread rolling machines can only achieve simple single feeding and cannot achieve automatic material storage and continuous layer feeding.

[0003] The existing thread rolling process has several drawbacks: First, manual feeding is labor-intensive, has uneven feeding speed, and low production efficiency, making it unsuitable for large-scale assembly line production. Second, manual feeding has poor positioning accuracy, and materials are prone to misalignment when entering the thread rolling assembly, resulting in insufficient thread machining accuracy, poor product consistency, and a high scrap rate. Third, traditional equipment lacks dedicated material inlet and outlet positioning structures, making materials prone to movement and misalignment during processing, further affecting thread rolling quality. Summary of the Invention

[0004] The purpose of this invention is to provide a thread rolling machine with an automatic feeding and positioning mechanism, which solves the problems of low efficiency of manual feeding, poor material positioning accuracy, poor consistency of thread rolling, and unstable equipment operation in the prior art, and realizes automated material feeding and precise feeding and positioning, thereby improving the accuracy and production efficiency of thread rolling.

[0005] A thread rolling machine with an automatic feeding and positioning mechanism includes a main unit and a feeding device for conveying materials to the main unit. The feeding device includes a storage tank, a feed trough, and a feeding mechanism that feeds materials from the feed trough into the main unit. The storage tank is equipped with a loading mechanism that lifts the materials to the feed trough, realizing automatic storage and layer-by-layer feeding and conveying of materials. The main unit consists of a thread rolling worktable and a thread rolling assembly set on the thread rolling worktable. A material inlet sleeve connecting the feed trough and one side of the thread rolling assembly is mounted on the thread rolling worktable. A material outlet sleeve is set on the other side of the thread rolling assembly on the thread rolling worktable. The double sleeve structure realizes the full-process guidance and positioning of material feeding and discharging. After the material is fed into the thread rolling assembly through the material inlet sleeve and completed thread rolling, it is discharged through the material outlet sleeve, realizing automated continuous processing.

[0006] Furthermore, the feeding mechanism includes a screw mechanism arranged along the feeding groove and a pusher slide that is driven by the screw mechanism to move along the feeding groove. The pusher slide has a feeding pusher block fixed in the feeding groove. Through precise transmission by the screw, the feeding pusher block is driven to push the material at a uniform speed, ensuring feeding accuracy and stability.

[0007] Furthermore, the feeding mechanism includes at least one fixed plate and a lifting plate. The fixed plate and the lifting plate are inclined and staggered in the storage trough. The lifting plate conveys the material layer by layer upward through lifting action. When the material is conveyed to the top of the fixed plate at the top layer, it rolls into the feeding trough. The staggered and inclined structure can realize the orderly layered conveying of materials and avoid material stacking and jamming.

[0008] Furthermore, a guide ramp is provided between the top of the fixed plate and the feeding chute to connect the two. The tops of both the fixed plate and the lifting plate are inclined surfaces. The inclined structure can use the material's own weight to achieve automatic sliding, ensuring smooth feeding without jamming.

[0009] Furthermore, the feeding mechanism also includes a lifting cylinder fixedly installed at the bottom of the storage tank and a lifting bracket fixedly connected to the telescopic rod of the lifting cylinder. The lifting plate is fixed on the lifting bracket, and the lifting plate is automatically raised and lowered by the cylinder drive, with stable power and strong controllability.

[0010] Furthermore, the thread rolling assembly includes a fixed thread rolling seat fixed on the thread rolling worktable and a movable thread rolling seat slidably disposed on the thread rolling worktable. Thread rolling heads are rotatably connected to the fixed thread rolling seat and the movable thread rolling seat respectively. The main unit is also provided with a drive mechanism for driving the thread rolling heads to rotate. The drive mechanism is provided with two output shafts, and universal telescopic shafts are correspondingly connected between the two output shafts and the two thread rolling heads, which can be adapted to the position adjustment of the movable thread rolling seat to ensure that the transmission is always stable.

[0011] Furthermore, the universal telescopic shaft consists of a telescopic connecting shaft in the middle section and universal joints connecting both ends of the telescopic connecting shaft. The telescopic connecting shaft is connected to the output shaft and the thread rolling head respectively through the universal joints. The telescopic connecting shaft includes a spline shaft and a spline sleeve. The spline shaft is slidably set in the spline sleeve, which can adaptively extend and retract, and finely adjust the angle, eliminating the problem of transmission jamming.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention sets up independent storage tanks, feeding tanks, and integrated feeding and feeding mechanisms, which can realize batch storage of materials, automatic layer-by-layer feeding, and precise push feeding, without the need for manual intervention throughout the process, greatly reducing the intensity of manual labor, significantly improving the automation level and production efficiency of thread rolling, and is suitable for batch production lines; This invention forms a full-process guiding and positioning structure through material inlet sleeves and material outlet sleeves, limiting and guiding the material feeding, processing, and discharging throughout the process, completely solving the problems of material deviation and movement in traditional equipment, greatly improving the accuracy of thread rolling and product consistency, and reducing the scrap rate.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] Please see Figures 1-4A thread rolling machine with an automatic feeding and positioning mechanism includes a main unit 1 and a feeding device 2 for conveying materials to the main unit 1. The feeding device 2 includes a storage tank 21, a feed trough 22, and a feeding mechanism 23 for feeding materials from the feed trough 22 into the main unit 1. The storage tank 21 is provided with a loading mechanism 3 for lifting materials to the feed trough 22, realizing automatic storage and layer-by-layer feeding and conveying of materials. The main unit 1 consists of a thread rolling worktable 11 and a thread rolling assembly 12 set on the thread rolling worktable 11. A material inlet sleeve 4 is mounted on the thread rolling worktable 11 to connect the feed trough 22 and one side of the thread rolling assembly 12. A material outlet sleeve 5 is provided on the other side of the thread rolling assembly 12 on the thread rolling worktable 11. The double sleeve structure realizes the full-process guidance and positioning of material feeding and discharging. After the material is fed into the thread rolling assembly 12 through the material inlet sleeve 4 and completed thread rolling, it is discharged through the material outlet sleeve 5, realizing automated continuous processing.

[0021] Furthermore, the feeding mechanism 23 includes a screw mechanism 231 arranged along the feeding groove 22 and a pusher block 232 driven by the screw mechanism 231 to translate along the feeding groove 22. The pusher block 232 is fixed with a feeding pusher block 2321 arranged in the feeding groove 22. Through precise transmission by the screw, the feeding pusher block 2321 is driven to push the material at a uniform speed, ensuring feeding accuracy and stability.

[0022] Furthermore, the feeding mechanism 3 includes at least one fixed plate 31 and a lifting plate 32. The fixed plate 31 and the lifting plate 32 are inclined and staggered in the storage tank 21. The lifting plate 32 conveys the material layer by layer upward through the lifting action. When the material is conveyed to the top of the top fixed plate 31, it rolls into the feeding tank 22. The staggered inclined structure can realize the orderly layered conveying of materials and avoid material stacking and jamming.

[0023] Furthermore, a guide ramp 221 is provided between the top of the top fixing plate 31 and the feeding trough 22 to connect the two. The tops of both the fixing plate 31 and the lifting plate 32 are inclined surfaces. The inclined structure can use the weight of the material to achieve automatic sliding, ensuring smooth feeding without jamming.

[0024] Furthermore, the feeding mechanism 3 also includes a lifting cylinder 33 fixedly installed at the bottom of the storage tank 21 and a lifting bracket 34 fixedly connected to the telescopic rod of the lifting cylinder 33. The lifting plate 32 is fixed on the lifting bracket 34, and the lifting plate 32 is automatically raised and lowered by the cylinder drive, with stable power and strong controllability.

[0025] Furthermore, the thread rolling assembly 12 includes a fixed thread rolling seat 121 fixed on the thread rolling worktable 11 and a movable thread rolling seat 122 slidably disposed on the thread rolling worktable 11. Thread rolling heads 12a are rotatably connected to the fixed thread rolling seat 121 and the movable thread rolling seat 122, respectively. The main unit 1 is also provided with a drive mechanism 13 for driving the thread rolling heads 12a to rotate. The drive mechanism 13 is provided with two output shafts 131. Universal telescopic shafts 14 are correspondingly connected between the two output shafts 131 and the two thread rolling heads 12a, which can be adapted to the position adjustment of the movable thread rolling seat 122 to ensure that the transmission is always stable.

[0026] Furthermore, the universal telescopic shaft 14 consists of a telescopic connecting shaft 141 in the middle section and universal joints 142 connected to both ends of the telescopic connecting shaft 141. The telescopic connecting shaft 141 is connected to the output shaft and the thread rolling head 12a respectively through the universal joints 142. The telescopic connecting shaft 141 includes a spline shaft and a spline sleeve. The spline shaft is slidably disposed in the spline sleeve and can adaptively extend and retract. With the angle compensation of the universal joint, it always ensures that the transmission between the drive mechanism 13 and the thread rolling head 12a is accurate and stable, avoids transmission jamming, and eliminates transmission jamming problems.

[0027] The working principle of this invention is as follows: (1) The staff stacks a batch of round rod-shaped materials in the storage tank 21. The lifting cylinder 33 reciprocates, driving the lifting plate 32 to continuously rise and fall. During the rising process, the lifting plate 32 lifts the bottom layer of materials upward. The material is then conveyed layer by layer by the staggered tilting structure. After the material is conveyed to the top of the top fixed plate 31, it slides down into the feeding tank 22 by its own weight through the guide ramp 221, completing the automatic feeding process. (2) After the feeding is completed, the screw mechanism 231 is started, driving the pusher slider 232 to move at a constant speed, which in turn drives the feed pusher block 2321 to push the material in the feed trough 22 and accurately push the material into the material guide sleeve 4 of the host 1. (3) After the material is pushed to the material inlet sleeve 4 by the feeding mechanism 23, it accurately enters the processing station between the two thread rolling heads 12a under the limiting and guiding action of the sleeve. The driving mechanism 13 drives the thread rolling heads 12a to rotate synchronously to complete the thread rolling of the outer wall of the workpiece. After the workpiece is processed, it smoothly passes through the thread rolling assembly 12 under the pushing action of the subsequent material, and is automatically discharged from the material outlet sleeve 5 on the other side, completing a single processing cycle and running continuously and automatically throughout the process.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
