[0002] This equipment is designed for efficient and precise thread rolling of parking screws. Its core innovation lies in the unique anti-deflection guide column structure, which works closely with the other components of the equipment to ensure the stability and high precision of the entire process, from material feeding to thread rolling, and effectively solves many problems existing in traditional thread rolling equipment.

[0003] Traditional parked screw thread rolling equipment mostly relies on manual unloading, which requires workers to keep a close eye on the equipment and frequently repeat the material picking and unloading actions. Manual operation not only consumes a lot of manpower and is labor-intensive, but is also easily prone to factors such as worker fatigue and distraction, resulting in the unloading speed being fast or slow, causing the guide column to tilt. This unstable unloading speed will seriously interfere with the normal operation of the thread rolling equipment, making the thread rolling process intermittent and greatly reducing production efficiency. In view of this, we propose a parked screw thread rolling equipment with an anti-deflection guide column structure. Summary of the Invention

[0024] like Figure 1 and Figure 3-4 As shown, the present invention relates to a parking screw thread rolling device with an anti-deflection guide column structure, comprising a machine tool 1, a thread rolling mechanism 2 arranged on the top of the machine tool 1, a feeding assembly 3 and an extrusion unit 4.

[0025] A support frame 11 is arranged on the top of the machine tool 1. A protective frame 12 is fixedly connected to one side of the top of the machine tool 1. Two tripods 13 are fixedly connected to one side of the top of the machine tool 1 near the protective frame 12 in a symmetrical structure.

[0026] The thread rolling mechanism 2 includes a first motor 21, which is fixedly connected to the right side of the machine tool 1. A transmission wheel 22 is movably connected to one side of the support frame 11 through an insert rod. The first motor 21 and the transmission wheel 22 are connected by a belt 23. A first bevel gear 24 is fixedly sleeved on the surface of the insert rod on the transmission wheel 22. A second bevel gear 25 is provided on the top side of the support frame 11 through an insert rod, and the first bevel gear 24 is meshed with the second bevel gear 25. The second bevel gear 25 is movably connected to a transmission rod 26 through a pin on the side away from the transmission wheel 22. A push rod 27 is slidably connected to the top of one of the tripods 13, and the push rod 27 is hinged to the transmission rod 26. A thread rolling plate 28 is fixedly connected to one side of the push rod 27.

[0027] Specifically, the second bevel gear 25 rotates, causing the thread rolling plate 28 to move back and forth through the transmission rod 26, thereby achieving a thread rolling effect.

[0028] like Figure 2-7 As shown, in the embodiment of the present invention, the feeding assembly 3 includes a feeding rack 31, the feeding rack 31 is fixedly connected to the top of the machine tool 1, the end of the insertion rod on the second bevel gear 25 is fixedly connected to the roller 32, and the roller 32 is arranged with an inclined annular surface 321 on the side away from the second bevel gear 25, and a movable rod 33 is hinged on one side of the support frame 11, and one end of the movable rod 33 is movably connected to the pulley 331, and the pulley 331 is in rolling contact with the inclined annular surface 321. One side of the two tripods 13 is slidably connected to a sliding rod 34, and the sliding rod 34 is hinged to the movable rod 33, and a first spring 35 is movably sleeved on the surface of the sliding rod 34, and the first spring 35 is fixedly connected to one of the tripods 13, and the sliding rod 34 is fixedly connected to a transmission block 36 at one end away from the first spring 35, and a material discharge plate 37 is fixedly connected to the output end of the feeding rack 31, and a blanking plate 38 is fixedly connected in the hole on the protective frame 12.

[0029] Specifically, the movable rod 33 slides on the surface of the inclined annular surface 321 through the pulley 331, causing the movable rod 33 to rotate axially, pushing the sliding rod 34 to move, causing the discharge plate 37 to reciprocate and translate, thereby achieving an automatic discharge effect.

[0030] When in use, the material is first placed inside the feeding rack 31, and then the first motor 21 drives the transmission wheel 22 to rotate through the belt 23 through the external circuit mechanism, and passes through the first bevel gear 24, meshing and driving the second bevel gear 25, causing one end of the transmission rod 26 to make a circular motion, driving the push rod 27 to make a reciprocating translation, causing the thread rolling plate 28 to move back and forth, realizing the thread rolling process. During the unloading process, the pulley 331 slides on the surface of the inclined annular surface 321, causing the movable rod 33 to move axially, pushing the slide rod 34 to move horizontally, causing the transmission block 36 and the discharge plate 37 to move at the same time, and the material moves downward from the feeding rack 31, and moves from the opening of the discharge plate 37 to the side of the thread rolling plate 28, realizing the material thread rolling.

[0031] The feeding assembly 3 of the present invention innovatively utilizes the rolling contact between the inclined annular surface 321 on the roller 32 and the pulley 331 when the second bevel gear 25 rotates, cleverly converting the circular motion into the axial rotation of the movable rod 33, thereby pushing the slide rod 34 and the translation discharge plate 37; the entire process does not require frequent manual intervention, realizing automatic feeding, and the feeding speed and position are precisely controllable; the stable feeding rhythm effectively avoids the thread rolling quality problems caused by unstable manual feeding, ensures the consistency of product quality, and reduces labor costs.

[0032] like Figure 2-3As shown, in an embodiment of the present invention, in an embodiment of the present invention, the extrusion unit 4 includes a second spring 41, the second spring 41 is fixedly connected to the inner wall of one side of the feed rack 31, and the inner wall of one side of the feed rack 31 is fixedly connected with a telescopic rod 42, and the telescopic rod 42 is movably sleeved inside the second spring 41, and the output end of the telescopic rod 42 is fixedly connected with an extrusion block 43, and the extrusion block 43 is slidably connected to the inside of the feed rack 31 and fixedly connected to the second spring 41, and the inner walls on both sides of the feed rack 31 are respectively arranged with a number of support plates 44 in a linear array, and the tops of two adjacent support plates 44 are movably connected with a hinge plate 45, and a hole 46 is opened on one side of the extrusion block 43, and a number of support plates 44 pass through the hole 46.

[0033] Specifically, during the discharge process, the extrusion block 43 slides inside the feed rack 31, causing several guide columns to maintain close contact during thread rolling to avoid tipping, which affects the movement of materials in the feed rack 31. During the discharge of materials, several support sheets 44 pass through the holes 46 to improve the orderly discharge function and prevent tipping.

[0034] When in use, during the unloading process, the second spring 41 applies a force to the extrusion block 43, causing the extrusion block 43 to move, and the telescopic rod 42 can be limited to move, and the material is continuously reduced, causing the support piece 44 to pass through the hole 46, which can prevent the material from dumping and move in an orderly manner, thereby improving the orderliness during unloading and preventing shaking and other conditions.

[0035] The present invention continuously applies force to the extrusion block 43 through the second spring 41, so that it slides stably in the feeding rack 31, and cooperates with the limiting function of the telescopic rod 42 to ensure that the guide column and the material always maintain close contact during the feeding and thread rolling process, effectively avoiding problems such as material dumping and deflection; the support pieces 44 and the hinge pieces 45 on the inner walls of both sides of the feeding rack 31 work together. When the material is reduced, the support pieces 44 pass through the holes 46 of the extrusion block 43, further ensuring the orderly movement of the material, greatly improving the orderliness of the material discharge, providing a stable material state for precise thread rolling, and significantly improving the product qualification rate.

[0036] Working principle: This embodiment provides a parking screw thread rolling device with an anti-deflection guide column structure. When in use, the material is first placed inside the feeding rack 31, and then the first motor 21 is operated through the external circuit mechanism. The output shaft of the first motor 21 rotates to drive the pulley to rotate, and the pulley drives the transmission wheel 22 to rotate through the belt 23, and passes through the first bevel gear 24, meshing and driving the second bevel gear 25, causing one end of the transmission rod 26 to make a circular motion, driving the push rod 27 to make a reciprocating translation, causing the thread rolling plate 28 to move back and forth, realizing the thread rolling process. During the material unloading process, the pulley 331 is on the inclined annular surface The surface 321 slides, causing the movable rod 33 to move axially, pushing the slide rod 34 to move horizontally, causing the transmission block 36 and the discharge plate 37 to move at the same time, and the material moves downward from the feed rack 31, and moves from the opening of the discharge plate 37 to the side of the thread rolling plate 28 to realize material thread rolling. In the process of unloading, the second spring 41 applies a force to the extrusion block 43, causing the extrusion block 43 to move, and it can be limited and moved by the telescopic rod 42. As the material is continuously reduced, the support piece 44 passes through the hole 46, which can prevent the material from dumping and move in an orderly manner, thereby improving the orderliness during unloading and preventing shaking and other conditions.
