The tubular connector has a stepped shaft structure, and one end of the tubular connector is provided with a plurality of tooth grooves extending along its axial direction.

[0037] The embodiment of this application discloses a highly efficient automatic thread rolling machine. Please refer to Figure 1 and Figure 2 , the highly efficient automatic thread rolling machine includes a frame 1, and a feeding mechanism 2, a clamping mechanism, and a threading mechanism 4 arranged on the frame 1. Among them, a slideway 11 matching the workpiece as shown in Figure 3 is arranged on the frame 1, and the workpiece can move in the slideway 11; the feeding mechanism 2 includes a vibrating bowl 21 and a conveying channel 22, and the vibrating bowl 21 can convey the workpiece along the conveying channel 22 to the starting end of the slideway 11; the clamping mechanism includes a clamping assembly 3, and the clamping assembly 3 includes a first linear driving member 31 and a telescopic assembly 32. The first linear driving member 31 is arranged on one side of the end of the slideway 11, and the first linear driving member 31 can drive the workpiece to move along the slideway 11. The telescopic assembly 32 is arranged on the other side of the end of the slideway 11, and the telescopic end of the telescopic assembly 32 is always in contact with the side of the workpiece facing away from the first linear driving member 31; the threading mechanism 4 includes a second linear driving member 41 and a forming tool 42. The forming tool 42 is clamped on the moving end of the second linear driving member 41, and the workpiece can be inserted into the forming tool 42 to form a tooth groove extending along the axial direction of the workpiece on the surface of the workpiece. In this embodiment, the first linear driving member 31 uses a cylinder, the second linear driving member 41 uses a hydraulic cylinder, and the clamping mechanism can clamp the large end of the workpiece and move in the slideway 11.

[0038] Thus, the workpiece can be selected by the vibrating bowl 21 and conveyed to the slideway 11 in the same posture. At this time, the machining end of the workpiece faces the threading mechanism 4, and the moving end of the first linear driving member 31 abuts against one side surface of the workpiece, and the telescopic assembly 32 abuts against the other side surface of the workpiece. When the first linear driving member 31 drives the workpiece to move, it can cooperate with the telescopic assembly 32 and clamp the workpiece to convey it to the end of the slideway 11. Then, the second linear driving member 41 drives the forming tool 42 to move and sleeved on the machining end of the workpiece, so as to form a tooth groove on the surface of the workpiece. Compared with the traditional thread rolling machine, the equipment provided by the present application is not affected by the rotation speed of the rocker arm mechanism during the machining of the workpiece, and by adjusting the stroke speed or working frequency of the first linear driving member 31 and the second linear driving member 41, the machining speed of the workpiece can be increased, greatly improving the machining efficiency. At the same time, this equipment does not need to adopt a rocker arm mechanism, and only relatively quiet components such as cylinders or hydraulic cylinders are needed to complete the machining, with low noise, small vibration, and small volume and floor area of the equipment, which can further adapt to the production environment of modern floor factories.

[0039] Preferably, in the present invention, the workpiece is a tubular connector having a stepped shaft structure as Figure 3 shown, the forming tool 42 is a hollow tube body, and a plurality of tool heads adapted to the tooth grooves are arranged on the inner side surface of the tube body. When the machining end of the workpiece is inserted into the forming tool 42, the plurality of tool heads cut the workpiece to form tooth grooves.

[0040] Specifically, please refer to Figure 1 and Figure 2, the telescopic component 32 includes a moving rod 321, a first fixing block 322, a second fixing block 323, an elastic member 324, a limiting block 325, and a plurality of connecting rods 326. Among them, the first fixing block 322 is fixedly arranged on the side surface of the frame 1; the second fixing block 323 is arranged on the side of the first fixing block 322 away from the frame 1, and the second fixing block 323 is connected to the first fixing block 322 through a plurality of connecting rods 326. In this embodiment, two connecting rods 326 are provided in total. Of course, in other embodiments, the number of connecting rods 326 can also be three, four or more; the moving rod 321 is slidably inserted into the slideway 11, and one end of the moving rod 321 away from the starting end of the slideway 11 can sequentially pass through the first fixing block 322 and the second fixing block 323 and extend to the side of the second fixing block 323 away from the frame 1. The moving rod 321 is slidably matched with the first fixing block 322 and the second fixing block 323 respectively, so that the moving rod can pass through the first fixing block 322 and slide and extend into the slideway 11; the limiting block 325 is fixedly arranged on the moving rod 321, that is, the limiting block 325 can move with the moving rod 321. The limiting block 325 can abut against the side surface of the first fixing block 322 facing the second fixing block 323, and when the limiting block 325 abuts against the first fixing block 322, the end of the moving rod 321 abutting against the workpiece is located on the side of the conveying channel 22 away from the first linear driving member 31. The limiting block 325 is used to limit the stroke of the moving rod 321; the elastic member 324 is sleeved on the moving rod 321, the elastic member 324 is located between the second fixing block 323 and the limiting block 325, and both ends of the elastic member 324 abut against the second fixing block 323 and the limiting block 325 respectively. The elastic member 324 generates a pulling force to always pull the moving rod 321 in the direction close to the starting end of the slideway 11.

[0041] Thus, the end of the moving rod 321 close to the first linear driving member 31 can always abut tightly against the workpiece and cooperate with the first linear driving member 31 to clamp the workpiece.

[0042] Preferably, please refer to Figure 1 and Figure 2, an adjusting block 5 is further provided on the frame 1. The connecting rod 326 is provided with threads. The connecting rod 326 sequentially passes through the first fixing block 322 and the adjusting block 5. First locking members 6 are provided on both sides of the first fixing block 322, and second locking members 7 are provided on both sides of the adjusting block 5. The first locking member 6 is in threaded connection with the connecting rod 326 and is used to fix the connecting rod 326, and the second locking member 7 is in threaded connection with the connecting rod 326 and is used to fix the adjusting block 5. In addition, a concave surface matching the workpiece is provided on the side of the adjusting block 5 close to the starting end of the slideway 11. When the cylinder drives the workpiece to move to the end of the slideway 11, the side of the workpiece facing away from the cylinder is located in the concave surface, thereby clamping the workpiece at the end of the slideway 11, which is convenient for the forming tool 42 to process the workpiece. Thus, the user can also adjust the position of the adjusting block 5 according to the change of the diameter size of the workpiece, so that the concave surface of the adjusting block 5 adapts to the processing of workpieces of different sizes, improving the practicability of the equipment.

[0043] Preferably, please continue to refer to Figure 1 and Figure 2 , the conveying channel 22 includes an arc segment 221 connected to the vibrating disk 21 and a vertical segment 222 connected to the arc segment 221. The end of the vertical segment 222 extends into the slideway 11. A second sensor 10 is provided on the vertical segment 222. The second sensor 10 is electrically connected to the first linear driving member 31 and the second linear driving member 41 respectively. The second sensor 10 is used to sense the workpiece in the conveying channel 22. When the second sensor 10 does not sense the workpiece, both the first linear driving member 31 and the second linear driving member 41 are powered off with a time delay, and the thread rolling machine stops working.

[0044] In addition, a baffle 9 is fixedly provided at the end of the vertical segment 222. The baffle 9 extends a certain distance along the length direction of the slideway 11 to seal a part of the notch of the slideway 11, so that it is difficult for the workpiece to shift during processing, reducing the clamping error of the clamping assembly 3, and thus enhancing the clamping accuracy of the clamping assembly 3.

[0045] Preferably, please refer to Figure 1 and Figure 2 , in the present invention, a plurality of slideways 11, clamping assemblies 3 and forming tools 42 can be provided. The plurality of forming tools 42 are arranged at the piston rod of the hydraulic cylinder, and each forming tool 42 corresponds to a slideway 11. The vibrating disk 21 can convey the workpiece to the starting end of each slideway 11, and each clamping assembly 3 is used to clamp the workpiece in the corresponding slideway 11. Thus, the equipment provided by the present application can realize the simultaneous processing of multiple workpieces by setting a plurality of forming tools 42 and slideways 11, etc., effectively improving the processing efficiency.

[0046] Specifically, please continue to refer to Figure 1 and Figure 2, the threading mechanism 4 further includes a tool mounting plate 43 which is fixedly arranged on the driving end of the second linear driving member 41, and a plurality of forming tools 42 are all mounted on the tool mounting plate 43. In addition, a plurality of guide rods 12 are arranged on the frame 1, and the threading mechanism 4 further includes a sliding plate 44 slidably sleeved on the guide rods 12. The second linear driving member 41 can drive the sliding plate 44 to make a reciprocating linear motion along the guide rods 12, and the tool mounting plate 43 is detachably arranged on the side of the sliding plate 44 facing the clamping mechanism. Thus, the second linear driving member 41, i.e., the hydraulic cylinder, can drive the plurality of forming tools 42 to move, and then process a plurality of workpieces simultaneously, effectively improving the processing efficiency of the workpieces.

[0047] Preferably, please refer to Figure 1 and Figure 2 , in the present invention, a blanking mechanism for discharging materials is further arranged on the frame 1. The blanking mechanism can be designed into a structure of ejecting by a thimble, that is, a corresponding thimble ejecting mechanism is arranged on the frame 1. When the forming tool 42 withdraws and returns to its position, the thimble ejecting mechanism acts, the piston rod of the air cylinder starts to retract, the thimble ejects the workpiece, and the workpiece falls off, realizing automatic blanking. In addition, the thimble ejecting mechanism can also be arranged on the tool mounting plate 43. And when the piston rod of the air cylinder retracts and disengages from the surface of the workpiece, the piston rod of the hydraulic cylinder retracts and drives the workpiece to disengage from the slideway 11. At this time, the workpiece is still located in the forming tool, and the thimble of the thimble ejecting mechanism is located in the forming tool 42. When the thimble ejects, the workpiece can be ejected to realize automatic blanking.

[0048] Furthermore, please refer to Figure 1 and Figure 2 , a first sensor 8 and a pneumatic chip blowing device are arranged on the frame 1. The first sensor 8 is arranged on one side of the guide rod 12, and the first sensor 8 is used for sensing the sliding plate 44. The air outlet end of the pneumatic chip blowing device can blow air towards the slideway 11. The first sensor 8 is electrically connected to the pneumatic chip blowing device to control the opening and closing of the pneumatic chip blowing device. And when the first sensor 8 senses the sliding plate 44 twice, that is, when the piston rod of the hydraulic cylinder retracts, the first sensor 8 transmits an electric signal to the pneumatic chip blowing device, and the pneumatic chip blowing device starts to blow air to blow off the iron chips in the slideway 11.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly.
