Description

Technical Field

[0001] This application relates to the field of thread rolling devices, and more particularly to a thread rolling device for machining mechanical parts. Background Technology

[0002] Threaded rods are made by rolling threads onto the surface of a cylindrical workpiece using a thread rolling machine. The manufacturing of threaded rods is a traditional industry with low requirements. Therefore, some small factories with limited funds can produce threaded rods by purchasing low-cost small thread rolling machines. However, small thread rolling machines usually require manual placement of the workpiece between two thread rolling wheels for thread rolling, followed by manual removal after completion. They can generally only operate on one threaded rod at a time, making them impractical. Furthermore, the completely manual handling of workpieces carries a high risk factor. Utility Model Content

[0003] To address the problems of small thread rolling machines, which typically involve manually placing the workpiece between two thread rolling wheels for thread rolling and then manually removing it after completion, and which generally can only operate on one threaded rod, resulting in low practicality and a high risk factor due to the entirely manual handling of workpieces, this application provides a thread rolling device for machining mechanical parts.

[0004] The thread rolling device for machining mechanical parts provided in this application adopts the following technical solution:

[0005] A thread rolling device for machining mechanical parts includes a housing with a discharge port through one side wall. Support plates are provided at both ends of the top surface of the housing. A drive assembly is provided on the top surface of each support plate, and the two drive assemblies are symmetrically distributed. Each drive assembly includes a connecting plate. Two connecting plates are provided, each located on the top surface of the support plate. A first threaded rod is provided between the two connecting plates. A movable block is fitted onto the outer wall of the first threaded rod. A top plate is provided on the top surface of the movable block. Rectangular plates are provided at both ends of the top surface of the top plate. A third threaded rod and a guide rod are provided between the two rectangular plates. A fixing block is fitted onto the outer wall of the third threaded rod and the guide rod. A shaft is transversely inserted through the fixing block. A circular plate is connected to the free end of the shaft, and a clamping assembly is provided on the circular plate.

[0006] Preferably, the clamping assembly includes positioning plates, four of which are circumferentially and equidistantly distributed on the outer wall of a circular plate. Each positioning plate is provided with a fourth threaded rod, one end of which is connected to a rotating plate, and the other end of which is connected to an arc-shaped clamping plate via a bearing.

[0007] Preferably, the top surface of the support plate has a sliding opening, the inside of the sliding opening has a slider, the slider is connected to the moving block, the output end of the first threaded rod passes through the connecting plate and extends outward to connect to the output end of the first motor, and one end of the third threaded rod passes through the rectangular plate and extends outward to connect to the output end of the second motor.

[0008] Preferably, a thread rolling assembly is provided between the two sets of drive components. The thread rolling assembly includes two crossbars, which are arranged parallel to each other on the top surface of the chassis. A slot is provided on the opposite side wall of each of the two crossbars. A second threaded rod and a round rod are respectively provided inside the two slots. One end of the second threaded rod passes through the crossbar and extends outward to be connected to a rotating handle.

[0009] Preferably, the outer walls of the round rod and the second threaded rod are fitted with L-shaped rods, the opposite sides of the two L-shaped rods are provided with second baffles, the top surfaces of the two cross rods are provided with first baffles, and thread rolling wheels are provided between the two first baffles and between the two second baffles.

The rotation of the first threaded rod drives the moving block and the slider to move along the horizontal direction of the sliding mouth towards the thread rolling assembly. Then, the output end of the second motor drives the third threaded rod to rotate. The rotation of the third threaded rod drives the fixed block to move along the horizontal direction of the guide rod towards the second baffle. Through the two sets of drive components, two pipe fittings can be rolled simultaneously, which greatly improves the working efficiency of the device.

[0012] 2. By rotating the rotating plate, the rotation of the rotating plate drives the fourth threaded rod to move, and the movement of the fourth threaded rod drives the arc-shaped clamping plate to move, thereby clamping and fixing pipes of different diameters, which greatly improves the thread rolling accuracy of the device.

The two ends of the third threaded rod 23 are respectively rotated with the two rectangular plates 27. The guide rod 22 is fixedly connected to two rectangular plates 27 at both ends. One end of the third threaded rod 23 passes through the rectangular plate 27 and extends outward to connect to the output end of the second motor 11. The outer walls of the third threaded rod 23 and the guide rod 22 are fitted with a fixing block 24. One end of the fixing block 24 is threadedly connected to the third threaded rod 23, and the other end is slidably connected to the guide rod 22. A shaft is fixedly inserted through the fixing block 24 laterally. A circular plate 25 is fixedly connected to the free end of the shaft. A clamping assembly is provided on the circular plate 25. The output end of the first motor 7 drives the first threaded rod 8 to rotate. The rotation of the first threaded rod 8 drives the moving block 12 and the slider 9 to move along the horizontal direction of the sliding opening 10 towards the thread rolling assembly 2. Then, the output end of the second motor 11 drives the third threaded rod 23 to rotate. The rotation of the third threaded rod 23 drives the fixing block 24 to move along the horizontal direction of the guide rod 22 towards the second baffle 161. The two sets of drive assemblies 4 can simultaneously perform thread rolling operations on two pipe fittings, greatly improving the working efficiency of the device.

[0020] Reference Figure 4 The clamping assembly includes four positioning plates 131, which are circumferentially and equidistantly distributed on the outer wall of the circular plate 25.

One end of the fourth threaded rod 28 is fixedly connected to a rotating plate 26, and the other end of the fourth threaded rod 28 is fixedly connected to an arc-shaped clamping plate 29 through a bearing. By rotating the rotating plate 26, the rotation of the rotating plate 26 drives the fourth threaded rod 28 to move, and the movement of the fourth threaded rod 28 drives the arc-shaped clamping plate 29 to move, thereby clamping and fixing pipes of different diameters, which greatly improves the thread rolling accuracy of the device.

One end of the thread rolling wheel 14 passes through the baffle and extends outward to connect to the output end of the third motor 15. By rotating the handle 21, the rotation of the handle 21 drives the second threaded rod 19 to rotate. The rotation of the second threaded rod 19 drives the L-shaped rod 18, the second baffle 161, the thread rolling wheel 14 and another L-shaped rod 18 on it to move along the horizontal direction of the round rod towards the first baffle 16. The output ends of the two third motors 15 respectively drive the thread rolling wheels 14 on them to rotate in the same direction, thereby realizing the thread rolling process of the pipe fitting.

[0022] The implementation principle of the thread rolling device for machining mechanical parts according to this application embodiment is as follows: In use, by rotating the rotating plate 26, the rotation of the rotating plate 26 drives the fourth threaded rod 28 to move, and the movement of the fourth threaded rod 28 drives the arc-shaped clamping plate 29 to move, clamping and fixing the pipe fitting. Then, the output end of the first motor 7 drives the first threaded rod 8 to rotate, and the rotation of the first threaded rod 8 drives the moving block 12 and the slider 9 to move along the horizontal direction of the sliding mouth 10 towards the thread rolling assembly 2.
