[0021] Reference Figure 1 to Figure 8, which is an embodiment of the present invention, provides a tapping machine for bolt processing, which is used for processing bolt external threads, including: a workbench 1 having a discharge channel 101; a tapping die 12 is arranged on the workbench 1; a receiving tube 3 is rotatably arranged on the workbench 1 and is located on one side of the tapping die 12, the receiving tube 3 is coaxially arranged with the tapping die 12, the side wall of the receiving tube 3 has a discharge port 304, and a rotary track groove 301 is opened on the top of the receiving tube 3; a push piece 4 is arranged on the workbench 1, and the push piece 4 is located on the side of the receiving tube 3 away from the tapping die 12, and the push piece 4 is used to push the bolt into the receiving tube 3; a driven rod 13 is slidably arranged on the workbench 1, and the driven rod 13 is arranged on the push piece 4, the driven rod 13 has a sliding end 1301, and the sliding end 1301 is slidably arranged in the rotary track groove 301, and after the driven rod 13 moves along the rotary track groove 301, the discharge port 304 is connected with or disconnected from the discharge channel 101.

[0022] In the above scheme, the workbench 1 is a rectangular plate, and the workbench 1 is provided with a discharge channel 101, which provides an output path for the processed bolts. A conveyor belt or a receiving basket can be installed on the other side of the discharge channel 101 to facilitate the collection of processed bolts. The tapping die 12 is placed on the workbench 1 for processing the external thread of the bolt. The accommodating cylinder 3 is rotatably arranged on the workbench 1, and is located on one side of the tapping die 12, and is coaxially arranged with the tapping die 12. The side wall thereof is provided with a discharge port 304, and the discharge port 304 is connected to the discharge channel 101, which is used for discharging the processed bolts. A rotary track groove 301 is opened on the top of the accommodating cylinder 3. When the push rod 402 moves along the rotary track groove 301, it can push the accommodating cylinder 3 to rotate when the curved portion 303 of the rotary track groove 301 moves, and at this time, the discharge port 304 can be connected to the discharge channel 101. The push piece 4 is arranged on the workbench 1 and is located on the side of the receiving tube 3 away from the tapping die 12, and its function is to push the bolt into the receiving tube 3 to prepare for subsequent processing. The driven rod 13 is slidably arranged on the workbench 1 and on the push piece 4, and its sliding end 1301 is slidably arranged in the rotary track groove 301, and controls the connection or cancellation of the connection state between the discharge port 304 of the receiving tube 3 and the discharge channel 101 by moving along the rotary track groove 301.

[0023] Working process: First, place the bolt to be processed at the position of the feed port of the receiving tube 3, and wait for the push piece 4 to work. Then the push piece 4 starts, pushes the bolt into the receiving tube 3 and continues to push the bolt close to one end of the tapping die 12, so that the part of the bolt to be processed extends out of the receiving tube 3. At this time, the end cap of the bolt is located in the receiving tube 3, and the cylindrical part of the bolt completely extends out of the receiving tube 3. Then the tapping die 12 starts to rotate and approaches the bolt at the same time to process the external thread of the bolt. After the processing is completed, the push piece 4 pulls the bolt back. In this process, the driven rod 13 moves with the push piece 4, and its sliding end 1301 moves along the rotary track groove 301 again. When the curved portion 303 of the rotary track groove 301 slides, it drives the receiving tube 3 to rotate, so that the discharge port 304 of the receiving tube 3 is connected with the discharge channel 101, and finally the processed bolt is discharged through the discharge channel 101.

[0024] The present invention changes the previous manual method of taking and placing the bolts to be processed and processed, realizes a certain degree of automated operation, saves manpower, improves work efficiency, and also reduces the risks brought by manual operation.

[0025] Furthermore, it also includes: the driver 7 is arranged on the workbench 1, the mounting seat 8 is arranged on the driver 7, and the tapping die 12 is detachably arranged in the mounting seat 8; there are a plurality of locking rods 9, and the plurality of locking rods 9 are arranged at intervals on the mounting seat 8, and the locking rods 9 are used to lock the tapping die 12.

[0026] In the above scheme, the driver 7 is arranged on the workbench 1 to provide a power source for the operation of the entire equipment. The mounting seat 8 is arranged on the output end of the driver 7. It should be noted that the mounting seat 8 can have a rod body with a telescopic structure, such as an electric push rod or a hydraulic rod, so as to drive the tapping die 12 close to or away from the bolt. It is also possible to install a linear slide rail under the driver 7, and drive the entire mounting seat 8 and the tapping die 12 close to or away from the bolt by means of an electric push rod, a hydraulic rod or a screw nut. The tapping die 12 is detachably mounted in the mounting seat 8, which is convenient for the replacement and maintenance of the tapping die 12. There are several locking rods 9 arranged at intervals on the mounting seat 8. The locking rods 9 can be fastening bolts or pins, etc. Their function is to firmly lock the tapping die 12 to ensure that the position of the tapping die 12 is stable during the processing, and there will be no loosening or other situations that affect the processing accuracy. Secondly, during processing, it is also necessary to spray coolant.

[0027] Working process: When the tapping die 12 needs to be replaced, first loosen the locking rod 9, take the original tapping die 12 out of the mounting seat 8, then put the new tapping die 12 into the mounting seat 8, and then fix it tightly with the locking rod 9. During the processing, the driver 7 starts, driving the mounting seat 8 and the tapping die 12 fixed on the mounting seat 8 to rotate, and then approaches the bolt to perform the external thread processing operation on the bolt. This device not only facilitates the replacement of the tapping die 12, but also can quickly replace the appropriate tapping die 12 according to different bolt processing requirements, thereby improving the versatility of the equipment; at the same time, the locking rod 9 ensures the stability of the tapping die 12, which helps to improve the processing accuracy and ensure the processing quality.

[0028] Furthermore, the tapping die 12 has a plurality of chip removal grooves 1201 .

[0029] In the above scheme, the tapping die 12 itself has a plurality of chip grooves 1201, which are directly arranged on the side of the tapping part, and the chips can be directly discharged through the chip grooves 1201. Moreover, the chip grooves 1201 also allow coolant to pass through to accelerate cooling and lubrication.

[0030] Working process: When the tapping die 12 processes the external thread of the bolt, a large amount of metal debris will be generated as the tap and other components cut the bolt. These debris will be discharged along the chip groove 1201 on the tapping die 12 to prevent the debris from accumulating in the processing area and affecting the processing accuracy and causing damage to the tapping die 12 and other components. The chip groove 1201 can timely and effectively discharge the debris generated by the processing, ensure the smooth processing process, improve the processing accuracy, extend the service life of the tapping die 12, and reduce equipment failures caused by debris accumulation.

[0031] Furthermore, it also includes: the guide rail seat 10 is arranged on the workbench 1, and the pushing member 4 and the accommodating tube 3 are both arranged on the workbench 1 through the guide rail seat 10.

[0032] In the above scheme, the guide rail seat 10 is set on the workbench 1, and the push member 4 and the accommodating tube 3 are installed on the workbench 1 through the guide rail seat 10. The guide rail seat 10 provides a stable installation foundation and precise sliding guide for the push member 4 and the accommodating tube 3, ensuring that they can move accurately along the set trajectory.

[0033] Working process: During the entire bolt processing process, the push piece 4 moves forward and backward along the guide rail seat 10 to realize the pushing and pulling operations on the bolt, ensuring the stability and accuracy of the movement of each component, so that the entire processing process proceeds in an orderly manner.

[0034] Furthermore, the pushing member 4 includes: a telescopic rod 401 is arranged on one side of the guide rail seat 10; a slider 403 is slidably arranged on the guide rail seat 10, and one end face of the slider 403 is arranged on the piston end of the telescopic rod 401; a push rod 402 is arranged at one end of the slider 403 away from the telescopic rod 401, and the push rod 402 is coaxially arranged with the accommodating tube 3, and the push rod 402 has a friction surface 4021, and the friction surface 4021 is used to abut the bolt.

[0035] In the above scheme, the push member 4 is composed of three parts. The telescopic rod 401 is arranged on one side of the guide rail seat 10. As a power output component, the telescopic rod 401 can be an electric push rod or a hydraulic rod, which can achieve reciprocating linear telescopic motion. The slider 403 is slidably arranged on the guide rail seat 10, and one end face of the slider 403 is connected to the piston end of the telescopic rod 401. The outer wall of the slider 403 has a groove, and the groove is adapted to the raised guide strip of the guide rail seat 10, which can ensure that the slider 403 slides smoothly along the guide rail seat 10 under the drive of the telescopic rod 401. The push rod 402 is arranged at one end of the slider 403 away from the telescopic rod 401, and is coaxially arranged with the accommodating tube 3. The push rod 402 has a friction surface 4021, such as a rubber pad or a plane with friction protrusions. The friction surface 4021 can be tightly abutted with the bolt to facilitate pushing the bolt to move. At the same time, the friction surface 4021 can also ensure that the bolt itself will not rotate during processing.

[0036] Working process: When the equipment is started to process, the telescopic rod 401 extends, pushing the slider 403 to slide along the guide rail seat 10 toward the receiving tube 3, and the slider 403 drives the push rod 402 to move synchronously. The friction surface 4021 of the push rod 402 abuts against the bolt and pushes it into the receiving tube 3 near the end of the tapping die 12. After the processing is completed, the telescopic rod 401 contracts, driving the slider 403 and the push rod 402 to pull back, completing the corresponding operation steps. Through the cooperation of the telescopic rod 401, the slider 403 and the push rod 402, the pushing and pulling back operations of the bolts can be achieved more accurately and stably, and the friction surface 4021 can ensure good contact and pushing effect with the bolts, which is conducive to the smooth progress of the entire processing flow.

[0037] Furthermore, the guide rail seat 10 has a slide groove 1001, and further includes: a connecting rod 11 is slidably disposed in the slide groove 1001, one end of the connecting rod 11 is disposed on the side wall of the slider 403; a driven rod 13 is disposed in the slide groove 1001, and one end of the driven rod 13 away from the sliding end 1301 is disposed on the other end of the connecting rod 11. The guide rail seat 10 also has a discharge channel 101, which is connected to the discharge channel 101 of the workbench 1.

[0038] In the above scheme, the guide rail seat 10 is provided with a slide groove 1001, and the slide groove 1001 is located at the top of the guide rail seat 10. The connecting rod 11 is slidably set in the slide groove 1001, and one end of it is connected to the side wall of the slider 403. The driven rod 13 is also set in the slide groove 1001, and the end of the driven rod 13 away from its sliding end 1301 (the end that cooperates with the rotating track groove 301) is set on the other end of the connecting rod 11. In this way, the slider 403, the connecting rod 11 and the driven rod 13 are connected into an associated motion mechanism to realize the transmission and coordination of actions, and the connecting rod 11 moves together with the slide rail.

[0039] Working process: When the slider 403 of the push member 4 moves along the guide rail seat 10, it will drive the connecting rod 11 connected thereto to slide in the slide groove 1001, and the connecting rod 11 will further drive the driven rod 13 to move, and the sliding end 1301 of the driven rod 13 will slide accordingly in the rotary track groove 301 of the accommodating cylinder 3, thereby driving the accommodating cylinder 3 to rotate, thereby realizing the switching of the discharge port 304 and the discharge channel 101 to be connected or cancel the connection state.

[0040] Furthermore, the rotary track groove 301 is U-shaped, and the curved portion 303 of the rotary track groove 301 is located on the side of the accommodating tube 3 away from the slider 403 .

[0041] In the above scheme, the sliding end 1301 of the driven rod 13 slides in the U-shaped rotating track groove 301. When the slider 403 moves toward the accommodating tube 3, the driven rod 13 will first enter the straight section of the rotating track groove 301. When the slider 403 abuts against the accommodating tube 3, the slider 403 stops moving. At this time, the push rod 402 is located in the middle position of the curved portion 303 of the rotating track groove 301. When the slider 403 returns, the driven rod 13 moves from the middle of the curved portion 303 of the track groove to another straight line. At this time, the accommodating tube 3 has completed its rotation, and the discharge port 304 is also connected to the discharge channel 101 at this time, completing the discharge of the processed bolts or preparing to receive the next state of the bolt to be processed.

[0042] Furthermore, after the telescopic rod 401 is retracted, a gap 1002 is formed between the top rod 402 and the accommodating tube 3, and also includes: a blanking plate 5 is obliquely arranged on one side of the workbench 1, the blanking plate 5 is opposite to the gap 1002, and the blanking plate 5 is used to accommodate the bolts to be processed; one end of the blocking rod 6 is arranged on the slider 403, and the other end of the blocking rod 6 is slidably penetrated on the blanking plate 5, and the blocking rod 6 is used to block the bolts to be processed.

[0043] In the above scheme, after the telescopic rod 401 is retracted, a gap 1002 is formed between the top rod 402 and the accommodating tube 3, and the blanking plate 5 is tilted and arranged on one side of the workbench 1 and facing the gap 1002, which is used to accommodate the bolts to be processed and facilitate the bolts to enter the appropriate processing starting position. One end of the blocking rod 6 is arranged on the slider 403, and the other end is slidably penetrated and arranged on the blanking plate 5, which plays the role of blocking the bolts to be processed and preventing the bolts from entering by mistake when they are not needed. A conveyor belt will be installed above the baffle plate, and there will only be one bolt to be processed in the baffle plate at a time. When the baffle plate is not blocked by the baffle rod 6, the bolt to be processed in the baffle plate will enter the gap 1002.

[0044] Working process: In the initial state, the blocking rod 6 blocks the bolts to be processed on the blanking plate 5. When the slider 403 moves under the drive of the telescopic rod 401, the blocking rod 6 moves synchronously with the slider 403 to release the blocking of the bolts, and the bolts can enter the end of the accommodating tube 3 through the gap 1002 between the top rod 402 and the accommodating tube 3 to wait for processing. During the processing, the blocking rod 6 can be restored to the blocking position driven by the slider 403 to prepare for the next round of processing operations. The orderly entry of the bolts to be processed into the processing position is controlled, the disorder of the processing process caused by the random entry of the bolts is avoided, and the automation control level and processing efficiency of the entire bolt processing are improved.

[0045] Furthermore, it also includes: a tapered cylinder 302 , the end surface of the tapered cylinder 302 with a smaller diameter faces the tapping die 12 , and the tapered cylinder 302 is used to adjust the coaxial center of the bolt and the tapping die 12 .

[0046] In the above scheme, the conical cylinder 302 is set at the corresponding position, and its end face with a smaller diameter faces the tapping die 12. The conical structure can guide the bolt so that the bolt can be better coaxial with the tapping die 12 to ensure the accuracy of the tapping process.

[0047] Working process: When the pusher 4 pushes the bolt toward the tapping die 12, the bolt will first contact the tapered cylinder 302, gradually move along the tapered inner surface of the tapered cylinder 302 to a position coaxial with the tapping die 12, and then enter the tapping die 12 for external thread processing, ensuring that the axis of the bolt and the axis of the tapping die 12 are basically coincident during the processing, thereby improving the processing quality. Effectively adjusting the coaxial state of the bolt and the tapping die 12 reduces the processing error caused by the axis deviation, improves the accuracy of the bolt external thread processing, and ensures product quality.

[0048] A processing method of a tapping machine for bolt processing, the specific steps are as follows: Step 1: The bolt enters the gap 1002 formed between the push rod 402 and the accommodating tube 3, and the bolt to be processed is in an initial position ready to enter the accommodating tube 3.

[0049] Step 2: The push rod 402 of the push member 4 is driven by the telescopic rod 401 to push the bolt into the accommodating tube 3 close to one end of the tapping die 12, and the part of the bolt to be processed extends out of the accommodating tube 3, so as to prepare for the tapping process.

[0050] Step 3: The tapping die 12 is driven by the driver 7 to rotate and approach the bolt, and the external thread is processed on the bolt portion extending out of the accommodating tube 3 . The debris generated during the processing is discharged through the chip removal groove 1201 of the tapping die 12 .

[0051] Step 4: After the processing is completed, the top rod 402 pulls back the bolt under the drive of the telescopic rod 401, and the driven rod 13 moves along the slider 403. The driven rod 13 moves along the rotary track groove 301 and drives the accommodating cylinder 3 to rotate, so that the discharge port 304 of the accommodating cylinder 3 is connected with the discharge channel 101. Step 5: The connected discharge channel 101 allows the processed bolts to be discharged smoothly, completing the entire bolt external thread processing process, and then the equipment can repeat the next round of bolt processing operations.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
