Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, and in particular to a thread rolling machine for shaft machining with a rotating structure. Background Technology

[0002] A thread rolling machine is a specialized machine for machining threads on shaft-type workpieces (such as bolts, screws, and shaft parts). Its core function is to apply pressure to the shaft workpiece using thread rolling plates, causing plastic deformation of the metal material and thus forming threads on the workpiece surface. The thread rolling machine uses two threaded plates, driven by a drive unit, to roll the shaft workpiece. When the thread rolling plates contact the workpiece surface, the pressure causes the metal material to flow plastically, gradually filling the thread grooves and forming a complete thread. Thread rolling machines are widely used in machinery manufacturing, automobile manufacturing, aerospace, and electronics industries. In these fields, threaded connections are a common type of connection, so thread rolling machines play an important role in the production process.

[0003] In existing technologies, thread rolling machines generally use a method where one thread rolling plate is fixed and another thread rolling plate moves linearly back and forth to perform thread rolling. This means that during the thread rolling operation, the thread rolling plate responsible for reciprocating movement must complete a full set of linear reciprocating movements before it can complete the thread rolling of a shaft-like workpiece. This reduces the thread rolling efficiency for shaft-like workpieces and lowers production efficiency. Therefore, it is necessary to improve the thread rolling machine for shaft processing by incorporating a rotating structure to solve the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 - Figure 7 This utility model provides an embodiment of a shaft machining thread rolling machine with a rotating structure, including a frame 1, a door frame 4 rotatably connected to the frame 1 via a rotating component, a rotating frame 21 rotatably connected inside the frame 1, a reduction gear assembly disposed inside the frame 1, a thread rolling disc 22 disposed on top of the rotating frame 21, a shaped block 23 disposed on top of the thread rolling disc 22, a fixed frame 26 disposed on top of the frame 1, a thread rolling bracket 28 disposed on top of the frame 1, a feed guide rail 213 fixedly connected to one side of the fixed frame 26, an L-shaped bracket 214 fixedly connected to the top of the frame 1, a sliding frame 215 slidably connected inside the L-shaped bracket 214, a reinforcing spring 217 fixedly connected between the sliding frame 215 and the L-shaped bracket 214, a baffle 216 fixedly connected to the end of the sliding frame 215 away from the reinforcing spring 217, a smooth rod 218 fixedly connected to the top of the sliding frame 215, and a rotating support rotatably connected inside the frame 1. The machine consists of a frame 211, a contact bearing 212 rotatably connected to the rotating support 211, and a feeding frame 219 fixedly connected to the top of the frame 1. The contact bearing 212 is in contact with the shaped block 23. The guide rod 218 is rotatably connected inside the rotating support 211. The rotation speed of the rotating frame 21 is reduced by a reduction assembly. When the tooth rolling disc 22 rotates counterclockwise, the outer surface of the contact bearing 212 contacts the outer surface of the shaped block 23, so that the shaft-type workpieces inside the feeding guide 213 are fed sequentially. The tooth rolling disc 22 and the tooth rolling frame 28 cooperate to perform tooth rolling operations on multiple sets of shaft-type workpieces at the same time, improving the tooth rolling efficiency of shaft-type workpieces, increasing production efficiency, and thus improving the practicality of the device. The reduction assembly rotates through the pinion 36 with the pressure plate 29, which in turn drives the rotating frame 21 to rotate, thereby improving the tooth rolling stability of shaft-type workpieces and improving the tooth rolling accuracy.

[0026] Please see Figure 1 - Figure 5In this embodiment, the L-shaped bracket 214 has a corresponding groove at the corresponding position of the sliding frame 215. The sliding frame 215 slides in the groove of the L-shaped bracket 214, limiting the baffle 216 so that it can only move in a straight line, thereby improving the stability of feeding. The inside of the toothed disc 22 is provided with mounting bolts 24, which are located inside the irregular block 23. The mounting bolts 24 are threadedly connected to the inside of the rotating frame 21. A washer 25 is provided between the mounting bolts 24 and the irregular block 23. A threaded rod 27 is fixedly connected to the top of the fixed frame 26. A pressure plate 29 is provided on the threaded rod 27. A mounting nut 210 is threadedly connected to the outside of the threaded rod 27. When the toothed disc 22 rotates counterclockwise, the outer surface of the contact bearing 212 contacts the outer surface of the irregular block 23, causing the feed guide rail 216 to move counterclockwise. The spindle-shaped workpieces inside the 13 are fed sequentially. Through the cooperation of the thread rolling disc 22 and the thread rolling frame 28, multiple sets of spindle-shaped workpieces can be thread rolled simultaneously, improving the thread rolling efficiency of spindle-shaped workpieces, reducing production efficiency, and thus improving the practicality of the device. The shaped block 23 and the thread rolling disc 22 have matching through holes at corresponding positions of the mounting bolts 24. The mounting bolts 24 are located inside the through holes of the thread rolling disc 22 and the shaped block 23, facilitating the installation and disassembly of the thread rolling disc 22 and the shaped block 23, thereby improving the thread rolling efficiency for different thread profiles. Two sets of thread rods 27, pressure plates 29, and mounting nuts 210 are provided, and these two sets are sequentially distributed on the top of the fixed frame 26, improving the installation stability of the thread rolling frame 28, and thus improving the thread rolling efficiency for different thread profiles.

[0027] Please see Figure 6 - Figure 7In this embodiment, the reduction assembly includes a support plate 31 fixedly connected inside the frame 1, a motor 32 fixedly connected to one side of the support plate 31, a reduction gearbox housing 33 fixedly connected to the side of the support plate 31 near the motor 32, a first bearing 35 disposed inside the reduction gearbox housing 33, an input shaft 34 disposed inside the first bearing 35, a pinion 36 fixedly connected to the input shaft 34, a second bearing 37 disposed inside the reduction gearbox housing 33, an output shaft 38 disposed inside the second bearing 37, a large gear 39 fixedly connected to the output shaft 38, and the input shaft 34 fixedly connected to the output end of the motor 32. The rotating frame 2... 1. Fixedly connected to the top of the output shaft 38, the pinion 36 meshes with the outside of the large gear 39. The pinion 36 drives the pressure plate 29 to rotate, which in turn drives the rotating frame 21 to rotate, thereby improving the stability of thread rolling on shaft-type workpieces and improving the thread rolling accuracy. Two sets of first bearings 35 are provided, and the two sets of first bearings 35 are symmetrically distributed on the gearbox housing 33, thereby improving the rotational stability of the input shaft 34 and improving the practicality of the device. Two sets of second bearings 37 are provided, and the two sets of second bearings 37 are symmetrically distributed on the gearbox housing 33, thereby improving the rotational stability of the output shaft 38 and improving the practicality of the device.

[0028] During operation, the tooth rolling disc 22 and the irregularly shaped block 23 are placed sequentially on top of the rotating frame 21. The mounting bolts 24, with washers 25 fitted on top, are then aligned and inserted into the through holes of the tooth rolling disc 22 and the irregularly shaped block 23. The mounting bolts 24 are threaded into the rotating frame 21, thus mounting the tooth rolling disc 22 and the irregularly shaped block 23 on top of the rotating frame 21. This facilitates the replacement of tooth rolling discs 22 with different tooth rolling specifications. The tooth rolling frame 28 is placed against the inner side of the fixed frame 26 and threaded into the threaded rod 27 using mounting nuts 210. The mounting nuts 210 on both sides press and fix the tooth rolling frame 28 against the pressure plates 29 on both sides. It facilitates the replacement of the tooth-rolling frame 28 with the same tooth-rolling specifications as the tooth-rolling disc 22. After installation, the motor 32 is started to drive the input shaft 34 to rotate. The input shaft 34 is housed inside the two sets of first bearings 35 on the gearbox housing 33, which improves the rotational stability of the input shaft 34. The small gear 36 meshes with the outside of the large gear 39, which drives the output shaft 38 to rotate. The two sets of second bearings 37 on the gearbox housing 33 further improve the rotational stability of the output shaft 38, thereby driving the rotating frame 21 to rotate inside the frame 1, which in turn drives the tooth-rolling disc 22 to rotate counterclockwise. The external storage is fed through the feed guide rail 213. The shaft-type workpieces in the material frame are conveyed sequentially. When the contact bearing 212, which is rotatably connected to the rotating bracket 211, contacts the protruding part of the irregular block 23, it causes the rotating bracket 211 to rotate inside the frame 1 away from the corresponding position of the thread rolling plate 22. The guide rod 218 is rotatably connected to the inside of the rotating bracket 211, causing the sliding frame 215 to slide inside the L-shaped bracket 214, compressing the reinforcing spring 217 and moving the baffle 216 away from the feed guide rail 213, making it easier to convey the shaft-type workpieces in the feed guide rail 213 sequentially. When the contact bearing 212 is in the recessed part of the irregular block 23, the pressure... The sliding frame 215, driven by the reinforcing spring 217, is reset, causing the baffle 216 to block the feed guide rail 213, preventing the feeding of shaft-like workpieces inside the feed guide rail 213. It is rotatably connected to the inside of the rotating bracket 211 through the smooth rod 218. The reinforcing spring 217 ensures that the outer surface of the contact bearing 212 is always in contact with the outer surface of the shaped block 23. The shaft-like workpieces entering between the tooth rolling plate 22 and the tooth rolling frame 28 are engaged with the tooth rolling frame 28 by the rotation of the tooth rolling plate 22, and then the teeth are rolled. After the teeth are rolled, the shaft-like workpieces are collected by the unloading frame 219 by the centrifugal force of the tooth rolling plate 22.

[0029] Through the above steps, when the thread rolling plate 22 rotates counterclockwise, the outer surface of the contact bearing 212 contacts the outer surface of the shaped block 23, so that the shaft-type workpieces inside the feed guide 213 are loaded sequentially. Through the cooperation of the thread rolling plate 22 and the thread rolling frame 28, multiple sets of shaft-type workpieces can be thread rolled at the same time, which improves the thread rolling efficiency of shaft-type workpieces. This solves the problem that when the thread rolling plate responsible for linear reciprocating movement has to complete a complete set of linear reciprocating movement before it can complete the thread rolling of a shaft-type workpiece, thus reducing the thread rolling production efficiency of shaft-type workpieces.
