Description

Technical Field

[0001] The present invention relates to the technical field of screw thread rolling equipment for parking screws, and more specifically, to a parking screw thread rolling equipment with an anti-deviation guide post structure. Background Art

[0002] This equipment is designed specifically for the efficient and precise thread rolling processing of parking screws. Its core innovation lies in the unique anti-deviation guide post structure, which closely cooperates with other components of the equipment. Throughout the process from material feeding to thread rolling, it ensures the stability and high precision of the processing, effectively solving many problems existing in traditional thread rolling equipment.

[0003] Traditional parking screw thread rolling equipment mostly relies on manual feeding, which requires workers to closely monitor the equipment at all times and frequently repeat the actions of taking and placing materials. Manual operation not only consumes a large amount of labor and has a high labor intensity, but also is extremely likely to cause the feeding speed to be erratic due to factors such as worker fatigue and distraction, resulting in the inclination of the guide post. This unstable feeding speed will seriously interfere with the normal operation of the thread rolling equipment, making the thread rolling process intermittent and greatly reducing the production efficiency. In view of this, we propose a parking screw thread rolling equipment with an anti-deviation guide post structure. Summary of the Invention

Adjacent two of the support pieces are movably connected with hinge pieces at the top. A hole is formed on one side of the extrusion block, and a plurality of support pieces pass through the hole; the distance between two opposite support pieces is adapted to the diameter of the guide post, which can prevent the guide post from tilting during feeding. Through ingenious design, the present invention achieves effects such as efficient feeding and prevention of guide post tilting; the thread rolling mechanism uses the transmission of helical gears and transmission rods to convert rotational motion into reciprocating linear motion of the thread rolling plate, improving the thread rolling efficiency, and realizes orderly feeding by passing a plurality of support pieces through the holes on the extrusion block, and can prevent the guide post from tilting by adapting the distance between adjacent two support pieces to the guide post.

[0008] Preferably, the thread rolling mechanism further includes a transmission rod hinged to one side of the second helical gear and a push rod hinged to one end of the transmission rod. The thread rolling plate is fixedly connected to one side of the push rod. The rotation of the second helical gear drives one end of the transmission rod to make a circular motion, causing the push rod to make a reciprocating motion.

[0009] Preferably, the feeding assembly further includes a roller fixedly connected to the end of the plug rod on the second helical gear. An inclined annular surface is arranged on one side of the roller away from the second helical gear.

[0010] Preferably, one side of the support frame is hinged with a movable rod.

[0017] As Figure 1 And Figure 3-4 Shown, a parking screw thread rolling device with an anti-deviation guide post structure involved in the present invention includes a machine tool 1, a thread rolling mechanism 2 arranged on the top of the machine tool 1, a feeding component 3 and an extrusion unit 4.

[0018] 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, and two tripods 13 are symmetrically fixedly connected to the top of the machine tool 1 near the protective frame 12.

[0019] The thread rolling mechanism 2 includes a first motor 21, the first motor 21 is fixedly connected to the right side of the machine tool 1, one side of the support frame 11 is movably connected with a transmission wheel 22 through a plug rod, the first motor 21 and the transmission wheel 22 are in transmission connection through a belt 23, a first helical gear 24 is fixedly sleeved on the surface of the plug rod on the transmission wheel 22, a second helical gear 25 is arranged on one side of the top of the support frame 11 through a plug rod, and the first helical gear 24 is meshed with the second helical gear 25. A transmission rod 26 is movably connected to the side of the second helical gear 25 away from the transmission wheel 22 through a pin. 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.

[0020] Specifically, when the second helical gear 25 rotates, through the transmission rod 26, the thread rolling plate 28 reciprocates to achieve the thread rolling effect.

[0021] 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 a roller 32, and the roller 32 is arranged with an inclined annular surface 321 on the side away from the second bevel gear 25, a movable rod 33 is hinged on one side of the support frame 11, and a pulley 331 is movably connected to one end of the movable rod 33, and the pulley 331 is in rolling contact with the inclined annular surface 321, and a sliding rod 34 is slidably connected to one side of the two tripods 13, 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 one end of the first spring 35. A transmission block 36 is fixedly connected to one end of the sliding rod 34 away from the first spring 35, and a discharge plate 37 is fixedly connected to one side of the transmission block 36, and the discharge plate 37 is slidably connected to the output end of the feeding rack 31, and a discharge plate 38 is fixedly connected in the hole on the protective frame 12.

[0022] 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.

[0023] 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 material 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.

[0025] like Figure 2-3As shown, in the 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 on one side of the feeding frame 31. A telescopic rod 42 is fixedly connected to the inner wall on one side of the feeding frame 31, and the telescopic rod 42 is movably sleeved inside the second spring 41. The output end of the telescopic rod 42 is fixedly connected to an extrusion block 43, and the extrusion block 43 is slidably connected inside the feeding frame 31 and fixedly connected to the second spring 41. A plurality of support pieces 44 are linearly arranged on the inner walls on both sides of the feeding frame 31 respectively. Hinge pieces 45 are movably connected to the tops of adjacent two support pieces 44. A hole 46 is formed on one side of the extrusion block 43, and a plurality of support pieces 44 pass through the hole 46.

[0026] Specifically, during the feeding process, as the extrusion block 43 slides inside the feeding frame 31, a plurality of guide columns keep in close contact during thread rolling, avoiding tipping and affecting the movement of materials inside the feeding frame 31. During the feeding of materials, a plurality of support pieces 44 pass through the hole 46, improving the orderly function of feeding and preventing tipping.

[0027] When in use, during the feeding 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 limit the movement. As the materials continuously decrease, the support pieces 44 pass through the hole 46, which can prevent the materials from tipping and move orderly, improving the orderliness during feeding and preventing conditions such as shaking.

[0028] In the present invention, the second spring 41 continuously applies a force to the extrusion block 43, enabling it to slide stably inside the feeding frame 31. With the limiting effect of the telescopic rod 42, it is ensured that the guide columns and the materials always keep in close contact during feeding and thread rolling, effectively avoiding problems such as material tipping and skewing. The support pieces 44 on the inner walls on both sides of the feeding frame 31 and the hinge pieces 45 work together. When the materials decrease, the support pieces 44 pass through the hole 46 of the extrusion block 43, further ensuring the orderly movement of the materials, greatly improving the orderliness of feeding, providing a stable material state for accurate thread rolling, and significantly improving the product qualification rate.

[0029] Working principle: This embodiment provides a parking screw thread rolling device with an anti-deviation guide post structure. When in use, first place the material inside the feeding rack 31, and then make the first motor 21 work through an external circuit mechanism. The output shaft of the first motor 21 rotates to drive the pulley to rotate. The pulley drives the transmission wheel 22 to rotate through the belt 23, and passes through the first helical gear 24 to meshingly drive the second helical gear 25, causing one end of the transmission rod 26 to perform a circular motion, driving the push rod 27 to perform a reciprocating translation, causing the thread rolling plate 28 to move reciprocally, and realizing the thread rolling process. During the feeding 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 translate, causing the transmission block 36 and the feeding plate 37 to move simultaneously. The material moves downward from the inside of the feeding rack 31 and moves to one side of the thread rolling plate 28 from the opening of the feeding plate 37, realizing the thread rolling of the material. And during the feeding 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 limit the movement. And as the material is continuously decreasing, the support piece 44 passes through the hole 46, which can prevent the material from tipping over and move orderly, improving the orderliness during feeding and preventing conditions such as shaking.
