[0028] Example:

[0029] A steel bar threading machine comprises a cabinet 1, a workbench 11 is arranged above the cabinet 1; the workbench 11 is provided with a clamping device 2, a threading device 3 and a driving device 4; the threading device 3 is arranged on the driving device 4, and the driving device 4 can drive the threading device 3 to move back and forth in a straight line; the clamping device 2 is used to clamp the steel bar; the threading device 3 is used to peel and thread the steel bar.

[0030] In this embodiment, the threading device 3 includes a peeling mechanism, a threading mechanism, a peeling length adjustment mechanism, a motor 32 and a reducer 31; the output shaft of the motor 32 is connected to the input shaft of the reducer 31, and the reducer 31 reduces the rotation speed and increases the torque; the output shaft of the reducer 31 is connected to the threading mechanism, and the threading mechanism is used to thread the steel bar; the threading machine is connected to the peeling mechanism to drive the peeling mechanism to rotate. The peeling mechanism, the threading mechanism, the reducer 31 and the motor 32 are coaxially arranged.

A guide rod 43 is also arranged on the workbench 11; a guide hole matching the guide rod 43 is arranged on the driving seat 42. The reducer 31 is arranged on the driving seat 42. Preferably, a handle 412 is arranged on the driving rod 41, and the driving rod 41 is driven to rotate by rotating the handle 412, and the gear on the driving rod 41 drives the tooth plate to move, thereby driving the reducer 31 and the electrode, threading mechanism, and peeling mechanism connected to the reduction base to move forward and backward. Preferably, two groups of guide rods 43 are arranged on the workbench 11, and the two groups of guide rods 43 are respectively located on both sides of the threading device 3, and the threading device 3 can be moved forward and backward along the axis through the guide rods 43.

[0032] In this embodiment, the peeling mechanism includes a cutter head 332 and a chuck 331; the chuck 331 is sleeved on the cutter head 332; the chuck 331 is extended or retracted to put the cutter head 332 in a working or non-working state. When the chuck 331 is extended, the limiting mechanism on the chuck 331 causes the cutter head 332 to move toward the central axis, and when the peeling mechanism moves toward the clamping device 2, the steel bar passes through the cutter head 332 to achieve cutting of the steel bar. When the chuck 331 is in a retracted state, the cutter head 332 is away from the central axis and no longer cuts the steel bar. The matching relationship between the chuck 331 and the cutter head 332 belongs to the conventional technical solution in this field, and will not be repeated here. Preferably, the drive seat 42 is connected to the second push rod, and the forward and backward movement of the drive seat 42 is completed by the second push rod.

[0033] In this embodiment, a stripping length adjustment mechanism is also included, and the stripping length adjustment mechanism includes a limiting component 34, a length adjustment component and a driving beam 344; the limiting component 34 is arranged on the length adjustment component; a limiting wheel 341 is arranged on the limiting component 34; the limiting wheel 341 is used to retract the chuck 331; the driving beam 344 is used to extend or retract the limiting wheel 341; the length adjustment component is used to adjust the position of the limiting wheel 341. The driving beam 344 is fixed on the driving seat 42.

[0034] In this embodiment, the limiting component 34 includes a limiting seat 342 and a limiting wheel 341 assembly; the limiting wheel 341 assembly includes a limiting wheel 341 shaft and a limiting wheel 341; the limiting wheel 341 is arranged on the limiting shaft 343; the limiting shaft 343 is arranged on the limiting seat 342; the limiting shaft 343 is also provided with a beam hole 3432; the driving beam 344 includes a narrow portion 3441 and a wide portion 3442; the narrow portion 3441 and the wide portion 3442 are transitioned through a smooth portion 3443; the narrow portion 3441 of the driving beam 344 is arranged at one end away from the driving seat 42, and the wide portion 3442 is arranged at one end close to the driving seat 42. The driving beam 344 passes through the beam hole 3432; after the beam hole 3432 moves from the narrow part 3441 to the wide part 3442, the limiting wheel 341 retracts; the limiting wheel 341 assembly also includes a reset mechanism; when the beam hole 3432 moves from the wide part 3442 to the narrow part 3441; the reset mechanism is used to extend the limiting wheel 341. The reset mechanism includes a reset cavity 3421 arranged on the limiting seat 342, and a reset plate 3431 arranged on the limiting shaft 343; it also includes a reset spring 3433, and the two ends of the reset spring 3433 are respectively connected to the reset plate 3431 and the limiting seat 342; when the limiting wheel 341 retracts, the reset spring 3433 is in an extruded state. When in use, the reset spring 3433 is in a non-compressed state, and the drive shaft extends out; when the chuck 331 on the stripping mechanism moves to the limiting wheel 341, due to the obstruction of the limiting wheel 341, the chuck 331 retracts, the cutter head 332 moves away from the central axis, and the steel bar stripping is terminated; at this time, since the threading is not completed, the threading device 3 still needs to move forward. In order to prevent the limiting wheel 341 from blocking the advancement of the threading device 3, the limiting wheel 341 needs to be retracted. The driving beam 344 moves along the axial direction following the driving seat 42; the limiting seat 342 is fixed in position, and the driving beam 344 moves in the beam hole 3432. When the beam hole 3432 passes through the smooth part 3443, that is, when the narrow part 3441 moves to the wide part 3442, the limiting shaft 343 moves perpendicular to the moving direction, driving the limiting wheel 341 to retract. On the contrary, the limiting wheel 341 extends out. The limiting wheel 341 can rotate on the limiting shaft 343 . When the rotating chuck 331 contacts the limiting wheel 341 , the limiting wheel 341 can be driven to rotate, thereby reducing the friction between the two and preventing damage to the limiting wheel 341 .

[0035] In this embodiment, the length adjustment component includes an adjustment seat 345; the adjustment seat 345 is arranged on the workbench 11; an adjustment rod 346 is arranged on the adjustment seat 345; an adjustment hole 3422 adapted to the adjustment rod 346 is arranged on the limit seat 342; the adjustment seat 345 can slide on the adjustment rod 346; a fixing screw is also arranged on the adjustment seat 345; the fixing screw extends into the adjustment hole 3422 and cooperates with the adjustment rod 346 to fix the adjustment seat 345. By adjusting the position of the limit seat 342 on the adjustment rod 346, the distance between the smooth part 3443 and the beam hole 3432 before processing can be changed. The longer the distance between the smooth part 3443 and the beam hole 3432 is, the longer the steel bar is peeled. On the contrary, the steel bar is peeled shorter. Preferably, a slot hole is arranged on the driving beam 344, and a screw hole is arranged on the driving seat 42; the driving beam 344 is fixed to the driving seat 42 through the slot hole 3444 and the screw hole. By changing the positional relationship between the screw hole and the slotted hole, the distance between the smooth portion 3443 and the drive shaft can be adjusted, thereby adjusting the length of the steel bar to be peeled. Preferably, a scale is provided on the adjustment rod 346. The scale can be used to better set the peeling length.

[0036] In this embodiment, a reset wheel is provided on the adjusting seat 345; the reset wheel is used to extend the chuck 331; the reset wheel is connected to the adjusting seat 345 via a reset shaft. After the threading is completed, the threading device 3 moves backward, and when the chuck 331 passes through the reset wheel, it is blocked by the reset wheel, the chuck 331 extends, and the cutter head 332 is close to the central axis to prepare for the next processing.

[0037] In this embodiment, the clamping device 2 includes a clamping mechanism and a driving mechanism; the clamping mechanism includes a bench vise; a clamping assembly is arranged on the bench vise; the clamping assembly includes a tooth seat 23 and a plurality of tooth parts 24; the plurality of tooth parts 24 are arranged on the tooth seat 23 at intervals; the tooth part 24 includes a plurality of teeth 241; an arc-shaped notch is arranged on the teeth 241; the teeth 241 are arranged vertically; the bench vise includes a first bench vise 21 and a second bench vise 22; the first bench vise 21 and the second bench vise 22 are arranged opposite to each other; the teeth 241 on the first bench vise 21 and the second bench vise 22 are staggered relative to each other; the first bench vise 21 and the second bench vise 22 can be close to or away from each other; the first bench vise 21 and the second bench vise 22 are driven to be close to or away from each other by the driving mechanism.

[0038] The first bench clamp 21 and the second bench clamp 22 are staggered. When viewed along the axis of the steel bar, the midpoint of the arc-shaped notch line is on the same axis, and the axis coincides with the axis of the threading device 3. When the first bench clamp 21 and the second bench clamp 22 are close to each other, the arc-shaped notches of the teeth 241 on the first bench clamp 21 and the second bench clamp 22 are close to each other, and the center parts are getting closer and closer, which can adapt to steel bars of different diameters. In addition, since the teeth 241 are vertically arranged, when the steel bar is placed between the teeth 241, during the process of the first bench clamp 21 and the second bench clamp 22 approaching each other, the steel bar can slide along the teeth 241 toward the center position, and finally the axis of the steel bar is in the center position of the arc groove. Through the above scheme, no matter what diameter of steel bar is clamped, the automatic centering of the steel bar can be achieved to avoid the deviation of the axis of the steel bar from the axis of the threading device 3.

The mounting groove and the tooth seat 23 are detachably connected, so that the tooth 241 can be replaced easily after the tooth 241 is damaged.

[0040] In this embodiment, the clamping mechanism further includes a first clamping seat 251 and a second clamping seat 252; the first clamping seat 251 and the second clamping seat 252 are connected by a guide rod 254 and a screw rod 253; the screw rod 253 is provided with a first thread segment and a second thread segment; the thread directions of the first thread segment and the second thread segment are opposite; the first bench vise 21 and the second bench vise 22 are respectively provided with bench vise holes matching the first thread segment and the second thread segment; the first bench vise 21 and the second bench vise 22 are also provided with guide holes matching the guide rod 254. The thread directions of the first thread segment and the second thread segment are opposite, and when the screw rod 253 rotates, the first bench vise 21 and the second bench vise 22 respectively arranged thereon move in opposite directions, so that the clamping or releasing effect can be achieved. The guide rod 254 can prevent the bench vise from rotating along the axis of the screw rod 253, so as to achieve its function of moving on the screw rod 253.

[0041] In this embodiment, the guide rod 254 includes a first guide rod 254 and a second guide rod 254; the first guide rod 254 and the second guide rod 254 are respectively arranged at two ends of the screw rod 253.

[0043] In this embodiment, the clamping device 2 further includes a toothed plate support assembly; the toothed plate support assembly includes a toothed plate support seat 263 and a toothed plate support roller 264 disposed on the toothed plate support seat 263; the toothed plate support roller 264 is disposed on the back of the first toothed plate 261; the first toothed plate 261 is in contact with the toothed plate support roller 264. The toothed plate support assembly can make the toothed plate and the gear mesh closely with each other to prevent the toothed plate and the gear from separating during the movement. Optionally, the first push rod 26 is one of an electric push rod, a pneumatic push rod and a hydraulic push rod.

[0044] In this embodiment, a chip receiving groove is provided on the cabinet 1; the chip receiving groove includes a bottom plate; the bottom plate is inclined; the bottom plate includes a high part and a low part; a chip outlet is also provided at one end of the chip receiving groove near the low part; a liquid leakage hole is provided on the bottom plate; a liquid receiving groove is provided below the chip receiving groove; a liquid baffle plate is provided on the chip outlet; and the liquid baffle plate is hinged to the chip receiving groove.

In this solution, the chip receiving groove is mounted on the upper edge, and the chip receiving groove does not protrude from the workbench 11 surface, making the surface neater.

[0046] Method of use: Adjust the position of the limiting wheel 341 according to the length of the threading and stripping, so that it is at a suitable distance from the smooth part 3443.

Start the motor 32, and the stripping mechanism and the threading mechanism rotate. Use the handle 412 to control the drive seat 42 to move toward the clamping device 2. The steel bar first contacts the stripping device; when the chuck 331 contacts the limiting wheel 341, the chuck 331 retracts; when the smooth part 3443 on the driving beam 344 contacts the limiting groove, it transitions to the wide part 3442, and the limiting shaft 343 is retracted; the threading mechanism continues to move forward, and the steel bar enters the threading mechanism to complete the threading; after the threading is completed, the motor 32 reverses, the handle 412 reverses, and retracts; the chuck 331 contacts the reset wheel and extends; the beam hole 3432 returns to the narrow part 3441, and the limiting shaft 343 extends.

[0047] Advantages of this solution: A leakage hole is provided on the bottom plate of the chip receiving trough, through which the cutting fluid can enter the liquid receiving trough at the lower end, thereby realizing the recovery of the cutting fluid. The bottom plate is in an inclined state, and after the iron chips are generated, they will move downward along the bottom plate and be discharged from the chip receiving trough. When the cutting fluid mixed with iron chips moves downward to the liquid baffle plate, it is blocked by the liquid baffle plate to prevent the cutting fluid from flowing out of the chip outlet and entering the liquid receiving trough below. When the iron chips accumulated at the liquid baffle plate are sufficient, the iron chips can be scraped off by flipping the liquid baffle plate. The above scheme makes it more convenient to discharge the iron chips.
