[0003] The existing numerical control machine tool usually adopts a pre-programmed mode to formulate the motion track of the tool, so as to accurately cut the clamped pipe, but in the actual debugging process, the operator may cause the tool to collide with the pipe during actual processing due to improper programming data input, thereby causing the tool to be damaged, therefore, in order to reduce such accidents, the device needs to be improved to ensure that the device can be debugged more safely.

[0007] Further, the shear component comprises: The lower surface of the straight push slide plate is connected with the outer surface of the connecting guide rail through a sliding groove, and the inner cavity of the side control plate is connected with the inner cavity of the straight push slide plate through a connecting wire, so that the side control plate controls the bottom pulley of the straight push slide plate to move along the connecting guide rail to further approach the processing rod; The bottom of the cutter clamping plate is fixedly connected with the upper surface of the straight push slide plate away from the side control plate; The outer surface of the cutting tool is connected with the inner cavity of the cutter clamping plate, and the cutter clamping plate clamps the cutting tool through the bolts on the top.

[0008] Further, the correction component comprises: The outer surface of the vertical guide rail is fixedly connected with the back of the inner wall of the container shell; The number of the control air pumps is two, and the control air pumps are symmetrically arranged on the upper and lower sides of the inner wall of the vertical guide rail.

[0009] Further, the correction component further comprises: The outer surface of the straight push cylinder is connected with the inner wall of the vertical guide rail, and hollow rubber tubes are symmetrically arranged on the upper and lower sides of the outer surface of the straight push cylinder, and the ends of the hollow rubber tubes away from the straight push cylinder are connected with the inner cavities of the control air pumps. The middle part of the outer surface of the detection disc is connected with the inner wall of the straight pushing cylinder through a connecting rod, and the axis of the detection disc is opposite to the axis of the machining rod after position adjustment, and the observation picture is perpendicular to the section of the machining rod, so that the distance between the cutting tool and the section of the machining rod can be observed.

[0010] Further, the auxiliary component comprises: The upper surface of the transverse guide shell is fixedly connected with the upper part of the inner wall of the container shell, and a guide sliding groove is formed in the middle part of the transverse guide shell. Both ends of the inner cavity of the bidirectional control plate are rotatably connected with torque rotating rods, and the upper surface of the bidirectional control plate is fixedly connected with the upper part of the inner wall of the transverse guide shell. The inner cavity of the friction rotating disc is inserted with the bottom end of the torque rotating rod.

[0011] Further, the auxiliary component further comprises: The upper surface of the sliding rotating drum is slidably connected with the inner wall of the transverse guide shell through the guide sliding groove. The outer surface of the transmission belt is rotatably connected with the inner cavity of the transverse guide shell through the cutting groove, the inner wall of the transmission belt is rollingly connected with the upper part of the outer surface of the sliding rotating drum, and the outer surface of the friction rotating disc is rollingly connected with the inner wall of the transmission belt. The inner wall of the control sleeve is rotatably connected with a control connecting rod, and the bottom end of the control connecting rod is inserted with a spraying mesh plate, which can spray downward from top to bottom after the air above is pressurized, and the control sleeve can make the spraying mesh plate below hover at a position outside the machining rod and keep a distance from the tool head by twisting the control connecting rod and the advancing control connecting rod.

The top end of the pressure spring belt is inserted with the inner cavity of the sensing element, and the bottom end of the pressure spring belt is inserted with the top of the lubricating sleeve. Although the contact roller is arranged at the bottom of the spraying mesh plate, it will slide to the inside of the spraying mesh plate along the sliding groove at the bottom of the spraying mesh plate when it is subjected to pressure from bottom to top, so as to pressurize the sensing element through the pressure spring belt.

[0013] The beneficial effects of the present application are as follows: 1. The device can thread the clamped machining rod through the shear component and tapping component, and perform related numerical control cutting work, when debugging the cutting tool, the cutting tool can be accurately controlled through the feedback picture of the detection disc, so that when actual cutting is performed, the cutting tool will not be damaged due to excessive tool lowering amount, and production accidents can be avoided.

[0014] 2. When the machining rod is cut, the rod body part of the machining rod will be cut by the cutting tool, resulting in a decrease in the diameter of the rod body. However, the detection disc is always facing the machining rod, and the diameter of the machining rod body inside the clamping component remains unchanged, so the diameter of the projection circle observed by the detection disc also remains unchanged. After each cutting, the cutting tool can be reset to the position of the outer diameter of the machining rod, so that when the cutting tool cuts the longer outer diameter part of the machining rod, it will not move directly from the cut part to the maximum outer diameter part of the machining rod, resulting in excessive tool lowering amount and tool damage.

[0015] 3. When the cutting tool cuts the machining rod, the debris separated from the machining rod will be randomly splashed into the inside of the container shell due to the centrifugal force generated by the high-speed rotation of the machining rod, resulting in a dirty inside of the container shell. The randomly splashed debris is also difficult to recover and clean, and the debris may be retained outside the guide rail, causing the shear component and tapping component to slip and be blocked. Therefore, when the machining rod is cut, the top of the spraying mesh plate will guide the debris straight into the slot in the middle of the guide rail through vertical blowing, thereby greatly reducing the splashing of debris inside the container shell and avoiding the above problems.

[0016] 4. The spraying mesh plate needs to hover at a height close enough to the machining rod to maintain a strong guiding effect. However, the spraying mesh plate is close to the machining rod, which may hinder the cutting work of the cutting tool. Therefore, a pressure sensing component is arranged inside the spraying mesh plate. The maximum advancing distance of the spraying mesh plate is determined by contacting the cutting tool, and then the spraying mesh plate is gradually pulled back until the sensing element is no longer triggered, and the best point of the spraying mesh plate is found, so that the spraying mesh plate can effectively guide the debris without hindering the normal work of the cutting tool.

[0023] The shear component 4 comprises: The straight push slide plate 43 is slidably connected with the outer surface of the connecting guide rail 44 through a sliding groove at the lower surface of the straight push slide plate 43, the inner cavity of the side control plate 41 is inserted with the inner cavity of the straight push slide plate 43 through a connecting wire, and the bottom pulley of the straight push slide plate 43 is controlled to move along the connecting guide rail 44 after the side control plate 41 is powered, so as to further approach the machining rod 15; The cutter clamping plate 45 is fixedly connected with the upper surface of the straight push slide plate 43 away from the side control plate 41 at the bottom of the cutter clamping plate 45; The cutting tool 46 is clamped with the inner cavity of the cutter clamping plate 45 at the outer surface of the cutting tool 46, and the cutter clamping plate 45 clamps the cutting tool 46 through the bolts at the top.

[0024] The correction component 5 comprises: vertical guide rail 51, the outer surface of the vertical guide rail 51 is fixedly connected with the back of the inner wall of the container shell 11; control air pump 52, the number of control air pump 52 is two, and the control air pump 52 is symmetrically arranged on the upper and lower sides of the inner wall of the vertical guide rail 51.

[0025] The correction part 5 further comprises: The straight pushing cylinder 54 is in sliding connection with the inner wall of the vertical guide rail 51, and the upper and lower sides of the outer surface of the straight pushing cylinder 54 are symmetrically provided with hollow rubber tubes 53, one end of the hollow rubber tube 53 away from the straight pushing cylinder 54 is inserted into the inner cavity of the control air pump 52, and the control air pumps 52 on the upper and lower sides change the actual length of the hollow rubber tube 53 by pressurizing the inside of the hollow rubber tube 53, so as to realize the effect of pushing the straight pushing cylinder 54; The detection disc 55 is in sliding connection with the inner wall of the straight pushing cylinder 54 through a connecting rod at the middle part of the outer surface of the detection disc 55, and the axis of the detection disc 55 is opposite to the axis of the machining rod 15 after position adjustment, and the observation picture is perpendicular to the cross section of the machining rod. Since the cutting tool 46 is pushed, the distance between the cutting tool 46 and the cross section of the machining rod 15 can be observed.

[0026] Before using the device to work, first pull open the two sides of the sliding cover 2, insert the rod body to be machined into the axis part of the clamping part 14 and fix it by screwing the clamping part 14, then close the sliding cover 2, and adjust the internal machining equipment through the internal console 17.

[0027] The internal console 17 drives the cutting part 4 and the tapping part 16 to slide to the position close to the machining rod 15. Since the cutting part 4 works first, the tapping part 16 stops after moving a distance, and the cutting part 4 continues to approach the machining rod 15. When the cutting part 4 passes through the horizontal position where the correction part 5 is located, it starts to decelerate, and then the correction part 5 starts. The control air pumps 52 on the upper and lower sides push the straight pushing cylinder 54 through the hollow rubber tube 53, so that the detection disc 55 vertically slides down until the axis position of the detection disc 55 is aligned with the axis position of the machining rod 15. At this time, the picture observed by the detection disc 55 is exactly perpendicular to the front end cross section position of the machining rod 15, which is a circular structure.

[0028] When the cutting tool 46 is about to approach the machining rod 15, the straight push sliding plate 43 will be horizontally pushed to the position close to the machining rod 15 under the control of the side control plate 41 along the connecting guide rail 44, at this time, the cutting tool 46 gradually approaches the machining rod 15, and the shadow of the cutting tool 46 gradually inserts into the cross section of the machining rod 15 from the observation of the detection disc 55, and the cutting amount of the cutting tool 46 can be quickly measured according to the pushing distance of the cutting tool 46, so that the cutting amount of the cutting tool 46 is ensured not to exceed the cutting range of the cutting tool 46, thereby avoiding the accident of hitting the tool.

[0029] After the cutting amount of the cutting tool 46 is controlled, the straight push sliding plate 43 stops moving, at this time, the clamping component 14 twists the machining rod 15 at high speed, and then the main sliding plate 42 continues to move to the position close to the machining rod 15 along the guide sliding rail 13, at this time, the cutting tool 46 contacts the machining rod 15, and the thread is cut on the outer surface of the machining rod 15, and the metal scraps cut off are dropped into the groove in the middle of the guide sliding rail 13, waiting for subsequent recycling work, after the thread machining of the machining rod 15 is completed, the detection disc 55 is first pulled upward, if drilling and tapping work is needed, the tapping component 16 is pushed to the position close to the machining rod 15 and the equipment is started to process, if the tapping work is not needed, the cutting component 4 is pulled away, the cutting component 4 is moved to the right along the guide sliding rail 13 and reset, and then the sliding cover 2 is opened to take out the machining rod 15 in the inside.

[0030] Embodiment 2, please refer to Figures 1-7 The application provides a technical scheme: on the basis of embodiment 1, the auxiliary component 6 comprises: The transverse guide shell 61 is fixedly connected with the upper portion of the inner wall of the container shell 11, and the guide sliding groove is arranged in the middle portion of the transverse guide shell 61. The two ends of the inner cavity of the bidirectional control plate 62 are rotatably connected with the torque rotating rods 63, and the upper surface of the bidirectional control plate 62 is fixedly connected with the upper portion of the inner wall of the transverse guide shell 61. The inner cavity of the friction rotating disc 64 is inserted with the bottom end of the torque rotating rod 63.

[0031] The auxiliary component 6 further comprises: The upper surface of the sliding rotating drum is slidably connected with the inner wall of the transverse guide shell 61 through the guide sliding groove. The outer surface of the transmission belt 65 is rotatably connected with the inner cavity of the transverse guide shell 61 through the cutting groove, the inner wall of the transmission belt 65 is rollingly connected with the upper portion of the outer surface of the sliding rotating drum, and the outer surface of the friction rotating disc 64 is rollingly connected with the inner wall of the transmission belt 65. The control sleeve 66 is rotationally connected to the control connecting rod at the center of the inner wall of the control sleeve 66, and the bottom end of the control connecting rod is inserted with the injection screen plate 67. The injection screen plate 67 can pass the air above through pressurization and spray from top to bottom. The control sleeve 66 can control the connecting rod and the advancing control connecting rod to make the lower injection screen plate 67 hover at the position outside the machining rod 15 and keep a distance from the tool head. The pressure sensing component 68 is symmetrically arranged on both sides of the inner cavity of the injection screen plate 67.

[0032] The pressure sensing component 68 includes: The sensing element 681 is fixedly connected to the inner cavity of the injection screen plate 67, and the top of the sensing element 681 is inserted with the control sleeve 66 through the connecting wire. The contact roller 684 is rollingly connected to the bottom of the inner cavity of the injection screen plate 67, and the upper part of the outer surface of the contact roller 684 is rotationally connected with the lubricating sleeve 683. The pressure spring belt 682 is inserted into the inner cavity of the sensing element 681 at the top end, and the bottom end is inserted into the top of the lubricating sleeve 683. Although the contact roller 684 is arranged at the bottom of the injection screen plate 67, it will slide to the inside of the injection screen plate 67 along the sliding groove at the bottom of the injection screen plate 67 when it is subjected to pressure from below, so as to pressurize the sensing element 681 through the pressure spring belt 682.

[0033] Before the machining rod 15 is subjected to thread cutting or tapping work, the auxiliary component 6 located at the upper part will first move the bottom injection screen plate 67 to the position directly above the position where the machining rod 15 needs to be processed, and then the control sleeve 66 pushes the injection screen plate 67 downward to make the injection screen plate 67 hover at the position directly above the outer surface of the machining rod 15, keeping a certain distance from the machining rod 15. When the machining rod 15 is processed, the injection screen plate 67 will vertically blow air to the rod body from top to bottom, guiding the debris separated from the machining rod 15 to fall vertically into the groove in the middle of the guide rail 13, so as to avoid the problem of random flying of debris inside the container shell 11 as much as possible.

[0034] When moving the injection screen plate 67, the bottom of the injection screen plate 67 will first contact the outer surface of the cutting tool 46, that is, after the contact roller 684 is in contact with and extruded by the cutting tool 46, the contact roller 684 is retracted into the inside of the injection screen plate 67. In the process of upward sliding, the contact roller 684 triggers the sensing element 681 by pressing the pressure spring belt 682. At this time, the injection screen plate 67 needs to be adjusted upward until the sensing element 681 is no longer subjected to pressure, so that the injection screen plate 67 is kept at a height close enough to the machining rod 15 and does not hinder the normal work of the cutting tool 46, so that the injection screen plate 67 has an effective guiding effect.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the protection scope of the present application.
